Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

The utility model provides a hold between fingers pushing-type safety lock, as shown in fig. 1-3, include: a lock base 1 and a lock catch 2; the lock catch 2 comprises a shell 3 and a buckle plate 4 which is arranged in the shell 3 and can be clamped with the lock seat 1; the shell 3 is provided with a pressing part 5; the shell 3 is provided with a sliding chute 6 for the pressing part 5 to move; the pinch plate 4 is provided with a first elastic piece 7 which is abutted with the inner bottom wall of the shell 3; when the pressing portion 5 is pressed and slides along the sliding groove 6, the latch 2 is separated from the lock holder 1. When unblanking, need press down earlier and press portion 5, then promote to press portion 5 to remove to keeping away from lock seat 1 direction along spout 6, make buckle 4 and lock seat 1 break away from the joint, just can accomplish and unblank.

Optionally, the pressing portion 5 includes a first key 8 and a second key (not visible and not shown) symmetrically disposed on two sides of the housing 3; a second elastic member 9; one end of the second elastic element 9 is fixed on the first key 8, and the other end is fixed on the second key; a first key hole 10 for the first key 8 to slide and a second key hole 21 for the second key to slide are respectively arranged on two sides of the shell 3; a third elastic piece 11 and a baffle 12 are arranged in the shell 3; one end of the third elastic member 11 is connected to the middle of the second elastic member 9, and the other end is connected to the baffle 12. When the lock is unlocked, the first key 8 and the second key which are positioned at two sides of the shell 3 are pressed simultaneously, so that the second elastic part 9 is compressed, then the first key 8 and the second key are pushed simultaneously to slide in the first key hole 10 and the second key hole 21 respectively, at the moment, the second elastic part 9 extrudes the third elastic part 11, and the fastener on the buckle plate 4 is separated from the lock seat 1 in a clamping manner, so that the lock can be unlocked; after the hand is loosened, the second elastic element 9 and the third elastic element 11 return to deform, so that the first key 8 and the second key return to the initial positions.

Optionally, a mounting groove 13 is formed in the housing 3, a mounting plate 14 is slidably disposed in the mounting groove 13, the lower ends of the first key 8 and the second key are provided with limit blocks 15, a limit groove 16 corresponding to the limit block 15 is formed in the sliding groove 6, and a first mounting hole 17 through which the first key 8 can penetrate and a second mounting hole 22 through which the second key can penetrate are formed in the mounting plate 14. When the lock is unlocked, due to the limitation of the limiting block 15 and the limiting groove 16, the first key 8 and the second key need to be pressed first, so that the first key 8 and the second key can be pushed only after the limiting blocks 15 on the first key 8 and the second key are separated from the limiting groove 16, and the unlocking difficulty is improved; wherein the mounting plate 14 can improve the stability of the first key 8 and the second key when pressed.

Optionally, the two sides of the upper end of the buckle plate 4 are both provided with protrusions 18, and the protrusions 18 are trapezoidal; after the pressing part 5 is pressed and slides along the sliding groove 6 to the side far away from the lock seat 1, the pressing part 5 extrudes the bevel edge of the bulge 18 to enable the buckle plate 4 to move downwards, and then the lock catch 2 can be separated from the buckle plate 4. When the lock is unlocked, the first key 8 and the second key are pressed simultaneously, the first key 8 and the second key slide along the first key hole 10 and the second key hole 21 respectively, at the moment, the two bulges 18 on the two sides of the buckle plate 4 are in contact with the first key 8 and the second key respectively, and under the action of the inclined edge, the first key 8 and the second key can generate downward acting force on the buckle plate 4 to enable the buckle plate 4 to move downwards, so that the fastener on the buckle plate 4 is separated from the lock seat 1.

Optionally, the first elastic piece 7 includes a first elastic piece 19 located below the second elastic piece 9, and two second elastic pieces 20 symmetrically disposed on two sides of the first elastic piece 19 and opposite to the extending direction of the first elastic piece 19; one end of each of the first elastic sheet 19 and the second elastic sheet 20 is fixed at the bottom of the buckle 4, and the other end of each of the first elastic sheet and the second elastic sheet is abutted against the inner bottom wall of the shell 3; the pinch plate 4 is provided with three abdicating grooves respectively corresponding to the first elastic sheet 19 and the two second elastic sheets 20. When the lock is unlocked, the pinch plate 4 moves downwards, and the first elastic sheet 19 and the two second elastic sheets 20 are extruded to deform; after the first key 8 and the second key are released, the pinch plate 4 is restored to the original position under the action of the first elastic sheet 19 and the two second elastic sheets 20; when the locking, can be directly impel hasp 2 to lock seat 1, the fastener on buckle 4 receives the effort and extrudees two second shell fragments 20 and produces deformation, and the fastener on the buckle board 4 gets into lock seat 1 back completely, and the second shell fragment loses the effort and replies deformation, makes buckle 4 reset to make buckle 4 and lock seat 1 joint.

Optionally, the bottoms of the first elastic sheet 19 and the second elastic sheet 20 are both provided with hemispherical bumps, and the bumps are abutted against the inner bottom wall of the outer shell 3. When first shell fragment 19 and second shell fragment 20 take place deformation, the lug receives the extrusion and slides on the inner bottom wall of shell 3, and reducible unblanking or locking in-process, the wearing and tearing between the inner bottom wall of first shell fragment 19 and second shell fragment 20 and shell 3 prolong the practical life of first shell fragment 19 and second shell fragment 20.

Optionally, the inner bottom wall of the housing 3 is provided with a plurality of positioning columns, and the buckle plate 4 is provided with a plurality of positioning holes corresponding to the plurality of positioning columns. In the embodiment, the number of the positioning holes is 4, the positioning holes are respectively positioned on the periphery of the buckle plate 4, when the lock is locked or unlocked, the buckle plate 4 always keeps straight-up and straight-down movement under the action of the positioning columns and the positioning holes, and the stability when the lock is locked or unlocked is ensured.

Optionally, for the convenience of installing the safety lock, the bottom surfaces of the lock catch 2 and the lock base 1 in this embodiment are provided with adhesive layers, and one side of the adhesive layers departing from the lock catch 2 and the lock base 1 is provided with a release film.

In the specific implementation in-process, when unblanking, press the first button 8 and the second button of 3 both sides of shell simultaneously earlier, treat that stopper 15 breaks away from spacing groove 16 after, promote first button 8 and second button and remove to protruding 18 directions along spout 6, the outer wall of first button 8 and second button contacts with the hypotenuse of protruding 18 and produces the extrusion, thereby produce decurrent power to buckle 4, buckle 4 moves down, thereby make the fastener on buckle 4 break away from with the joint of lock seat 1, can unblank.

The utility model discloses a hold between fingers pushing-type safety lock, the step of unblanking is comparatively complicated, and needs the operation of continuous coordination to effectively avoid the infant to unblank.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
