Abstract
The invention discloses a rotary self-lock pull head, which comprises a pull head body, a cap and a hook; the hook resists into the cap and moves upward and downward in an opening arranged on the pull head body according to a spring sleeved outside the hook; and the cap is fixedly arranged on the pull head body in a rotation manner. The action of the pull head body is realized by pulling the cap. The pull head is a novel self-lock pull head via the rotation in a threading way to realize the self-lock and the unlocking. By the utilization of the principle of working in the threading way, according to the rotation of the cap, the pull head is enabled to move upward and downward in the rotation manner, an upright hook arranged in the cap in an elasticity way is enabled to move upward and downward, and the unlocking and the self-lock are realized. The cap can be used as a pull sheet, and the number of combining parts is reduced. According to the self-lock pull head, the self-lock and unlocking of the pull head can not be realized unless removing the locking of a fixing piece, thus the self-lock pull head can be applied in clothing, a case and a tent which are self-locked or without a lock in a long term, and the self-lock pull head is provided with a certain anti-theft function.
Description
Technical field
The present invention relates to a kind of slide fastener, refer to especially the zipper head of a kind of rotary self-locking and release.
Background technology
At present, using widely, the self-locking zipper head is comprised of slider of zipper fastener body, a horse hook, a cap and a pulling-on piece.Can consult Chinese patent literature in CN201160563 number " a kind of slider of zipper fastener " (patent No.: CN200720058045.X) of invention disclosed patent on December 10th, 2008.The pull head of this patent is Split type structure, combines with the nut upper and lower pull head that is tightened.Though this pull head can prevent others easily opening slide fastener, just can not realize auto-lock function, use very inconvenience.Slide fastener with antitheft and auto-lock function also has, but mostly adopt outlet structure, can consult Chinese patent literature in CN202425725U number " a kind of anti-theft zipper lock buckle device " (patent No.: CN201120483776.5) of on 09 12nd, 2012 disclosed Chinese invention patents, its external locker, directly be buckled in zipper head on the locker with the left-hand thread tongue, not disguised, security is not high.And at present disguised antitheft slider of zipper fastener also has, and can consult Chinese patent literature in CN101843390A number " a kind of anti-pickpocket zipper puller " (patent No.: CN200910106185.3) of on 09 29th, 2010 disclosed Chinese invention patents.This pull head is to use a push button switch to realize release by the monodirectional locking shell fragment that a draught line is built in pull head inside, has concealed anti-theft feature, but its structure very complex, the draught line of employing rapid wear, security protection is unstable.
Summary of the invention
Problem for prior art exists the invention provides a kind of rotary self-locking pull head simple in structure.This pull head can not be subjected to the impact of external force, and unfixing rotation is to realize self-locking and release, can be used in to be in for a long time on self-locking or long-term dress ornament, case and bag and the tent without lock, possesses simultaneously certain anti-theft feature.
For achieving the above object, technical solution of the present invention is:
Rotary self-locking pull head, this pull head comprise a pull head body, a cap and a horse hook; The horse hook is resisted against in the cap, and by being sheathed on its outer spring, knee-action in the perforate that the pull head body is provided with; The cap rotation is fixed on the pull head body.
Further, convex with threaded column on the pull head body, the cap threaded column that is spirally connected is fixed on the pull head body.
Further, the be spirally connected threaded column of upper cap forms the die that restriction cap is deviate from its top.
Further, comprise that also one is a tight fit in the fixture on the threaded column, this fixture locking cap is on threaded column.
Further, move described pull head body by the pulling cap.
Pull head of the present invention is a kind of Novel self-lock pull head that uses screw thread rotation to realize self-locking and release.It uses the screw thread operation principle, makes its up or down spinning movement by the rotation cap, and the upright horse hook that elasticity is arranged in the cap is mobile up and down, realizes release and self-locking.Cap is wider thicker than the cap of prior art, is suitable for the handgrip pulling, and the function that can be used as pulling-on piece is used, and reduces the combiner of pull head.The present invention adopts fixture to make cap not deviate from easily the pull head body, the locking of not removing fixture is to realize the self-locking of pull head and release, can be used on dress ornament, case and bag and the tent that is in for a long time self-locking or long-term nothing lock, possess simultaneously certain anti-theft feature.

The explanation of accompanying drawing main mark:
Slider of zipper fastener body 1, cap 2, upright horse hook 3, spring 4, bolt (rivet) 5.
The specific embodiment
The present invention now is described in conjunction with the accompanying drawings and embodiments.
Rotary self-locking pull head shown in Fig. 1-7, this pull head comprise a pull head body 1, a cap 2 and the hook 3 of always pulling up a horse.Compared with prior art, cap 2 of the present invention is wider thicker, and after being suitable for handgrip and living, move described pull head body by pulling cap 2, cap 2 can be used as the function of pulling-on piece and uses, and has reduced the building block of pull head.
Convex with threaded column 12 on the pull head body 1 of the present invention, cap 2 of the present invention is secured on the pull head body 1 by being screwed onto this threaded column 12.
During assembling, spring 4 at first is positioned in the perforate 11 of pull head body 1; Then upright horse hook 2 is put into spring 4, rotates cap 2 on the threaded column 12 of pull head body 1 again, and thread-rolling screw post 12 upper ends make cap 2 can not screw out pull head body 1, realize the assembling of this self-locked draught part.
In order to make cap 2 not deviate from easily pull head body 1, the present invention locks the fixed form of cap 2 on pull head body 1 to be had:
One, dispose a fixture that is a tight fit on the threaded column 12, this fixture locking cap 2 makes cap 2 not deviate from easily pull head body 1 on threaded column 12.
Embodiment one, and fixture as Figure 1-3 is a bolt 5, and its through hole that passes on the cap 2 directly is screwed onto on the threaded column 12.The step surface that the bolt head of abduction is withheld on cap 2 through holes can not screw out the rotation cap, to lock cap 2 on pull head body 1.
Embodiment two, and as shown in Figure 7, described fixture also can be a rivet 5, and its through hole that passes on the cap 2 is directly rabbeted in threaded column 12.The step surface that the manufactured head of abduction is withheld on cap 2 through holes can not screw out the rotation cap, to lock cap 2 on pull head body 1.
Two, the mode that adopts threaded column directly to fix:
Embodiment three, shown in Fig. 4-6, the present invention also can be on being spirally connected the top of the threaded column 12 of cap 2, directly form the die 121 that restriction cap 2 is deviate from.The step surface that the manufactured head of abduction is withheld on cap 2 through holes makes the rotation cap can not screw out to lock cap 2 on pull head body 1.
Because there is active force upwards in spring 4 all the time by upright horse hook 3 extruding, in conjunction with the screw thread operation principle, rotation cap 2 rotates up or down and can make upright horse hook 3 mobile up and down, realizes release and self-locking.
Above-mentioned only is the specific embodiment of the present invention, but design concept of the present invention is not limited to this, allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
