Abstract
The utility model discloses an anti-shear device of a padlock. The anti-shear device is arranged in a latch hook of the padlock and comprises a clamp cover and a fastener. An arc groove is formed in the outer side edge of the clamp cover and used for being embedded into the inner wall of the latch hook, racks are arranged on opposite faces of columns on the two sides of the clamp cover respectively, and toothed threads matched with the racks are arranged on the two sides of the fastener. The clamp cover and the fastener are arranged on the inner wall of the latch hook, the purpose of adjusting the effective closure area of the latch hook is achieved through rack meshing of the fastener and the clamp cover, the anti-shear device can adapt to different items to be locked, and the gap between the latch hook and an item to be locked is reduced. Thus, locks can be prevented from being damaged through hydraulic tongs. In addition, the anti-shear device has the effects of preventing the locks from waggling and lowering noise.
Description
Technical field
The utility model relates to lock technology field, relates in particular to the anti-device of cutting of a kind of padlock.
Background technology
At present, the padlock of selling on the market, include the lock body of rectangular build and be located at the U-shape lock hook on lock body, although constantly the diameter of overstriking latch hook obtains better anti-theft effect, but the padlock overall weight of bringing thus increases, carry inconvenience, and the raising of cost, be that a lot of manufacturers and customer are difficult to accept.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of padlock is anti-cuts device, thereby take the padlock that solves prior art causes as improving the anti-ability of cutting the problem that inconvenience and cost improve of carrying.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the anti-device of cutting of a kind of padlock, it is located in the latch hook of padlock, comprise chuck and fastener, the lateral border of described chuck is provided with arc groove in order to be embedded in latch hook inwall, on the forward surface of described chuck both sides cylinder, be respectively equipped with tooth bar, described fastener both sides are provided with the groove matching with described tooth bar.
Adopt above structure compared with prior art, the utlity model has following advantage: the utility model by arranging chuck and fastener on latch hook inwall, fastener and chuck mesh to reach by tooth bar the object that regulates the effective sealed area of latch hook, thereby the adaptive different closure for the treatment of, reduce latch hook and treat the gap between closure, therefore can prevent from being destroyed lockset by hydraulic tongs, also there is in addition the lockset of preventing and rock, reduce the effect of noise.
As preferably, it is U-shaped that described latch hook and chuck are all, and described chuck is flexible element.Flexible element can make chuck can have certain crooking ability, is breaking into two with one's hands after chuck laterally, and adjustable fastener is engaged on the tooth bar of diverse location.
As preferably, described chuck comprises left chuck and right chuck, described left chuck and right chuck are hinged by hinge in upper end, and described left chuck and right chuck are also provided with extension spring between two link surfaces of upper end, and described extension spring struts left chuck and right chuck moves laterally.Chuck is taken out, and the active force of extension spring makes left chuck and right chuck separate to both sides, and adjustable fastener is engaged on the tooth bar of diverse location.
As preferably, a side bottom of described chuck is provided with to be sheathed on the collar of latch hook movable end.The collar is sheathed on latch hook, prevents that chuck from being taken out easily.
As preferably, the medium position of described fastener upper and lower end face is provided with the finger pressure groove connecting on front and rear wall.The convenient finger of finger pressure groove is mediated on fastener, conveniently uses hand operation.
As preferably, described fastener is provided with the baffle plate extending to both sides length direction, agree with mutually the to lead motion of described fastener of the sidewall of described baffle plate and tooth bar.Baffle plate the kinetic stability that has increased fastener is set, prevent that fastener from dropping out chuck when regulating.
