Abstract

The utility model relates to a lock, in particular to a lock for locking a gun trigger, which comprises a lock body and a buckle plate. The gun trigger lock is characterized in that the lock body mainly comprises a metal shell, a metal protective plate, a lock rod and a lock core, wherein the lock core is enclosed in the metal shell and the metal protective plate, the metal protective plate is provided with a semi-open lock cylinder protruding outwards, the lock rod with the shape matched with the shape of the lock cylinder is arranged in the lock cylinder, the lock core drives the lock rod to rotate, one side of the lock rod is provided with stepped buckle teeth; the buckle plate is provided with a lock hole matched with the lock rod, a lock plate matched with the buckle teeth of the lock rod is arranged in the lock hole, and the lock cylinder of the lock body is inserted in the lock hole of the buckle plate, so that buckle teeth on the lock rod in the lock cylinder can clamp the lock plate in the lock hole, thereby locking a gun trigger. The utility model has the advantages of simple structure, low processing difficulty and humanistic design. Moreover, the utility model has good anti-sawing performance and good anti-pulling performance, thereby achieving good preventive effect.

Description

A kind of gun trigger lock

Technical field

The utility model belongs to a kind of lockset, refers to a kind of lockset of the gun trigger that is used to lock especially.

Background technology

Commercially available gun trigger lock mostly is lock body and buckle is formed, a kind of trigger lock is disclosed as Chinese patent literature CN 2615627, form by lock body and buckle, this lock body is equiped with a core and locking plate in a lock core, and lock core is coated on the inside with a metal shell and metal casing, wholely again coat a watertight composition in the injection molding mode; This buckle sets firmly two locking bars on a metal base plate, this metal base plate is outer to coat a watertight composition with injection molding; Two locking bars of buckle are inserted two jacks of lock body, and the locking plate in this lock body just is snapped in locking bar, pins with the trigger with gun.

But above-mentioned similar trigger lock structure is still comparatively complicated, and the process and assemble difficulty is bigger, and lock body and buckle adopt the mode of part assembling after-baking more, and bulk strength haves much room for improvement.

Summary of the invention

The utility model provides the trigger lock of a kind of lock body and buckle die cast at above the deficiencies in the prior art.

The technical solution of the utility model is:

A kind of gun trigger lock comprises lock body and buckle, it is characterized in that:

This lock body mainly is made up of metal shell, metal casing, locking bar and lock core, in metal shell and metal casing are coated on lock core, establish the semi open model lock of evagination on the metal casing, establish the locking bar that shape and lock adapt in the lock, lock core drives locking bar and rotates, and a side of locking bar is provided with step-like buckle teeth;

This buckle is provided with the lockhole that matches with locking bar, establishes the locking plate that adapts with the locking bar buckle teeth in the lockhole;

The lock of aforementioned lock body inserts the lockhole of buckle, makes buckle teeth on the locking bar in the lock engage with locking plate in the lockhole and the trigger of gun is locked.

Optimally, the lock bottom has stopper slot, and the locking bar bottom is provided with a flange with the lock corresponding position, and lock peripheral metal backplate is provided with some shock structures.

A nearlyer step ground, the inboard sheathed rubber cushion of lock body and buckle is established the projection that some limit trigger move on the rubber cushion.

The metal shell of lock body described in the utility model and buckle are the die cast metal moulding, again outsourcing one watertight composition.

Wherein, the utility model adopts to be established corresponding buckle teeth on the step-like buckle teeth of locking bar and the locking plate and engages the structure that locks, has the good stability of a system, for further strengthening the stability of a system, also offer stopper slot and install flange, improved the anti-performance of pulling out of lockset in locking bar bottom corresponding positions in the lock bottom;

Lock body and buckle adopt the integral die-cast moulding, have improved the bulk strength of lockset, have strengthened anti-saw performance, and adopt the design of outer packaging waterproof layer, avoid the lockset internal wetted and cause situation about can't normally open after locking;

Consider that the whole main component of lockset is a metal, may cause the mutual wearing and tearing with the gun trigger after the use, thus between lock body and buckle, set up rubber cushion, and, more help fixing of trigger by the convex design on the rubber cushion;

The utility model structure is comparatively simple, has reduced difficulty of processing, designs humanizedly, has also simultaneously that good anti-saw is anti-to pull out performance, has reached good strick precaution effect.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the gun trigger lock comprises lock body 10 and buckle 20, this lock body 10 mainly is made up of metal shell 11, metal casing 12, locking bar 13 and lock core, in metal shell 11 and metal casing 12 are coated on lock core, establish the semi open model lock 14 of evagination on the metal casing 12, establish the locking bar 13 that shape and lock 14 adapt in the lock 14, lock core drives locking bar 13 and rotates, and a side of locking bar 13 is provided with step-like buckle teeth 15;

This buckle 20 is provided with the lockhole 21 that matches with locking bar 13, establishes the locking plate 22 that adapts with the locking bar buckle teeth in the lockhole 21, and locking plate 22 is provided with reverse step-like buckle teeth 23; Lock 13 inserts the lockhole 21 of buckles 20, makes buckle teeth 15 on the locking bar 13 in the lock 14 engage with locking plate 22 in the lockhole 21 and the trigger of gun is locked; Lock 14 bottoms have stopper slot 16, and locking bar 13 bottoms and lock 14 corresponding positions are provided with a flange 17, and lock 13 peripheral metal backplates 12 are provided with some shock structures 18; Lock body 10 and buckle 20 inboard sheathed rubber cushion 30a, rubber cushion 30b establish the projection 31 that some limit trigger move on the rubber cushion.

The replacement that should be pointed out that any simple concept all should be considered as simple deformation of the present utility model, belongs to protection domain of the present utility model.
