Abstract
The utility model relates to a laminated padlock which comprises a lock body (1) formed by a plurality of laminated pieces through overlapping, a lock cylinder (2) arranged in the lock body (1) and a lock beam (3) connected to the lock body (1), and the locking and unlocking of the lock beam (3) is controlled by the lock cylinder (2). The bottom end of the lock cylinder (2) is provided with a drill-preventing plate (21), and the hardness of the drill-preventing plate (21) is higher than that of the lock cylinder (2). Due to the arrangement of the drill-preventing plate at the bottom end of the lock cylinder and the strength of drill-preventing plate is high, the laminated padlock is prevented from being drilled broken, and safety performance of the laminated padlock is improved.
Description
Technical field
The utility model relates to a kind of lockset, relates in particular to a kind of laminated padlock.
Background technology
Lockset is the ordinary articles in people's daily life, kind has varied, padlock is a kind of lockset of relatively commonly using, laminated padlock is a kind of more welcome a kind of lockset that in recent years occurs on the market, its lock body is formed by stacking by multilayered metal film, a kind of high-tensile strength laminated padlock is disclosed such as Chinese utility model patent manual CN202627730U, as shown in Figure 1, include interconnective lock body 1 and lock bridge 2, described lock body 1 forms by some sheet metal 11 stacks and with rivet 12 riveteds, but lock bridge 2 lockings, be connected to lock body 1 one ends with opening, be provided with lock core assembly 3 in the described lock body 1, lock core assembly 3 includes lock gall 31, steel ball 32, thumb wheel 33 and disc spring 34; Be provided with the steel ball chamber in the described lock body 1, just ball 32 is located in the steel ball chamber, and with the locking of laminated padlock be open in the steel ball chamber and roll, and part is stuck in the locking groove 21 of described lock bridge 2 or in the unlatching recess of thumb wheel 33.Consist of stepped the arranging of described sheet metal 11 rims of both sides, top, the steel ball chamber inwall of described lock body 1 inside, and have the contact point more than three between the described steel ball 32 at least.Like this, this laminated padlock can be by a plurality of contact point between the sheet metal in steel ball and the steel ball chamber, effectively pulling force is distributed on the sheet metal of corresponding contact point, the tension strength that can bear strengthens greatly, efficiently solve the problem that the traditional structure sheet metal is out of shape, breaks through by the pulling force punching easily, durable, reliable, theftproof performance is better.Yet the lock core 3 of this laminated padlock is generally made by the metal of easy processing owing to need to offer a plurality of hole slots, easy drilled destruction, and theftproof performance is not good.
The utility model content
Technical problem to be solved in the utility model provides the laminated padlock that a kind of lock core is unsuitable drilled, theftproof performance is good.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of laminated padlock, comprise lock body that multi-layer stacks stack forms, be located at the lock core in the lock body and be connected to the lock bridge of unblanking and shutting by this lock core control on this lock body, wherein, the bottom of described lock core is provided with anti-drilling board, offer the hole of passing for key in the middle of this anti-drilling board, the hardness of this anti-drilling board is higher than the hardness of lock core.
After adopting said structure, because the bottom of lock core is provided with anti-drilling board, and the intensity of this anti-drilling board is higher, play the drilled bad effect that prevents, improve the security performance of lock, and lock core adopts existing common metal to make, do not affect at the relevant hole slot of lock core processing.
As further improvement in the technical proposal, wherein, described lock body comprises the base plate that offers for the lockhole of key plug and rotation, and the radial dimension of this lockhole is less than the radial dimension of anti-drilling board.
As further improvement in the technical proposal, wherein, be provided with thrust spring between described base plate and the anti-drilling board, the elastic force of this thrust spring makes anti-drilling board be close to described lock core bottom face.Thrust spring is exerted all one's strength anti-drilling board toward lock core cover direction like this, can play anti-drilling function, and anti-drilling board can rotate in lamination.
As further improvement in the technical proposal, wherein, the lamination between described base plate and the anti-drilling board is provided with locating hole or the locating slot of the described thrust spring in location.
As further improvement in the technical proposal, wherein, described anti-drilling board can rotate in described lamination.
In order to make lock body end face better appearance, as a kind of improvement of technique scheme, described lock body comprises the top board that is positioned at the lock body top layer, offers lock beam hole flexible for described lock bridge and that rotate on this top board.
As further improvement in the technical proposal, wherein, described multi-layer stacks is integrally formed described lock body by rivet.
As further improvement in the technical proposal, wherein, described multi-layer stacks is made by metal material.
As further improvement in the technical proposal, wherein, described anti-drilling board profile is circle or rectangle.
As further improvement in the technical proposal, wherein, described anti-drilling board is fixed in the lock body.
Description of drawings
Fig. 1 is that the solid of a kind of laminated padlock of the prior art splits structural representation.
Fig. 2 is the sectional structure schematic diagram of a kind of laminated padlock of the utility model.
Fig. 3 is the structure for amplifying schematic diagram of A part among Fig. 2.
The specific embodiment
See also Fig. 2 and Fig. 3, a kind of laminated padlock of the utility model comprises lock body 1, is located at lock core 2, lock bridge 3 in the lock body 1.
The structure of above-mentioned lock body 1, lock core 2, lock bridge 3 and the annexation between them, except the following stated difference, other parts adopt prior art to get final product, and are not improvements of the present utility model, are not described in detail at this.
See also Fig. 2, the bottom of lock core 2 is provided with anti-drilling board 21, the centre of anti-drilling board 21 offers the hole 15 of passing through for key, the profile of anti-drilling board 21 can be circle, and the radial dimension of lockhole 10 is less than the radial dimension of anti-drilling board 21, especially less than the outside dimension of anti-drilling board 21 on the base plate 11, can improve like this security performance of lock, be not easy drilled badly, the hardness of anti-drilling board 21 is higher than the hardness of lock core 2, has further guaranteed the security performance of lock.Be provided with thrust spring 4 between base plate 11 and the anti-drilling board 21, the elastic force of this thrust spring 4 makes anti-drilling board 21 be close to described lock core 2 bottom faces, anti-drilling board 21 can rotate in the lamination of lock body 1 like this, lamination between base plate 11 and the anti-drilling board 21 is provided with locating hole or the locating slot of location thrust spring 4, thrust spring 4 can have two, be arranged at respectively the both sides in the hole 15 of anti-drilling board 21, so that anti-drilling board 21 is pressed close to the stressed even of lock core 2 bottom faces.
