Abstract

The utility model provides an anti-theft zipper head of convenient and low cost, which comprises a noumenon used to make the chain joggle or apart and a code lock arranged on the noumenon to lock or release the noumenon, wherein a self-locking spring is arranged on the noumenon to prevent the noumenon gliding and is provided with a melt axis that traverses through the mid-empty part between the upside and the downside of the self-locking spring. The utility model saves the zipper patch and working procedures and cost in production arts with the code lock arranged on the zipper head, only need to turn the code loop to right location to move the slide fastener conveniently in operation. The utility model mainly is used in cases of using slide fastener, such as bags, notebooks and gifts package.

Description

A kind of antitheft pull head

Technical field

The utility model relates to a kind of slide fastener, relates in particular to a kind of antitheft pull head.

Background technology

Existing slide fastener when it is applied to briefcase, notebook, case and bag and so on, is opened in order to prevent slide fastener, has plenty of the pulling-on piece of slide fastener is fixed in an end of slide fastener by padlock, just have only the key holder can open padlock and then pulling slide fastener like this; The case and bag that have for convenience, on slide fastener, be provided with two can move toward one another pull head, when two pull head move toward one another during to a certain position, the pulling-on piece of two pull heads is fixed on the coded lock jointly, does not know that like this people of password just can not open case and bag.The latter not only makes complex manufacturing because two pull heads are set, and cost increases, and especially for small-sized pull head, pulling-on piece is fixed in certain location is very difficult something on the coded lock.

Summary of the invention

The purpose of this utility model provides a kind of antitheft pull head easy to use, with low cost.

The technical solution of the utility model is such: a kind of antitheft pull head comprises the body that is used to that sprocket is meshing with each other or throws off and is located at the coded lock that is used to lock or discharge body on the body.

Above-mentioned antitheft pull head is provided with the self-locking reed that is used to prevent the ontological idea of freedom slip in the described body, described coded lock is provided with a bearing pin, and described bearing pin passes through the hollow space between self-locking reed upside and the downside.

The utility model like this on production technology is saved operation and cost by directly being located on the pull head and saving parts such as pulling-on piece to coded lock, during operation if the rotational password circle to the tram, can mobile easily slide fastener, use very convenient.

Description of drawings

Fig. 1 is applied to the schematic diagram of notebook for embodiment;

Fig. 2 is the stereogram of embodiment;

Fig. 3 is the three-dimensional exploded view of embodiment;

The specific embodiment

Design philosophy of the present utility model is: thus coded lock directly is located on the pull head of slide fastener by the moving of cipher control pull head, reduce the processing step and the parts of pull head on the one hand, reduce cost, simplify the operation and the use of pull head simultaneously.

With reference to figure 1, the front cover of notebook 1 and back cover are locked in together by slide fastener 2, and slide fastener 2 is provided with antitheft pull head 3.

With reference to figure 2, described antitheft pull head 3 comprises the body 4 that is used to that sprocket is meshing with each other or throws off and is located at the coded lock 5 that is used to lock or discharge body 4 on the body 4.

With reference to figure 3, be provided with self-locking reed 41 in the described body 4, described self-locking reed 41 comprises integrally formed last floor 411 and following floor 412, in use, following floor 412 is arranged in and prevents between the adjacent sprocket of chain that pull head 3 from moving voluntarily.Described coded lock 5 comprises support 51, be located at two password circles 52 on the support 51, spring 53, lock core 54, bearing pin 55, respectively and password circle 52 adaptive and be sheathed on cipher ring 56 between password circle 52 and the lock core 54.Whole coded lock 5 itself is as known technology, do simple the introduction at this: be provided with locating slot 511 on the described support 51, described body 4 is provided with the positioning boss 42 adaptive with described locating slot 511, described bearing pin 55 is arranged on the described locating slot 511, and described bearing pin 55 mid portions are arranged on the self-locking reed 41 between the floor 411 and following floor 412, described lock core 54 lower surfaces support is located at floor 411 tops, like this, when support 51 moves, bearing pin 55 and then moves, thereby makes self-locking reed 41 be subjected to a thrust that makes progress.

In use, push lock core 54 downwards by support 51 top hollow spaces and move down, rotate two password circle 52 setting codes, discharge lock core 54 then it is resetted.When the pulling pull head when 1 liang of front cover of notebook is in the close position, rotational password circle 52 is upset the password of setting,, this moment, lock core 54 propped up self-locking reed 41 tops, self-locking reed 41 can not move up, pull head 3 can not move on slide fastener.Otherwise, when rotating two password circles 52 to the password position set, the elastic force promotion cipher ring 56 that lock core 54 can overcome spring 53 moves up, bearing pin 55 laterally moves and can give 41 1 thrusts that make progress of self-locking reed like this, thereby drive down and move away sprocket on the floor 412, and then pull head 3 can move freely.

Claims

1, a kind of antitheft pull head is characterized in that comprising the body that is used to that sprocket is meshing with each other or throws off and is located at the coded lock that is used to lock or discharge body on the body.

2, antitheft pull head as claimed in claim 1 is characterized in that being provided with in the described body self-locking reed that is used to prevent the ontological idea of freedom slip, and described coded lock is provided with a bearing pin, and described bearing pin passes through the hollow space between self-locking reed upside and the downside.
