Abstract

The utility model relates to an opening-closing device of a door lock battery box cover, which comprises a pushbutton (1), a spring (2), a rear locking surface (3) and a battery box cover (4). The spring (2) is arranged between the pushbutton (1) and the rear locking surface (3); the battery box cover (4) is provided with a through hole which is sleeved on the pushbutton (1), forms a limit structure with the pushbutton (1) and is buckled with clamp slots 31 and 34 on the rear locking surface (3) as a whole through clamp points 41 and 44; the pushbutton (1) is arranged in a groove of the rear locking surface (3) and pressed in the groove of the rear locking surface (3) when the spring (2) is compacted under the external force; and the battery box cover (4) can move horizontally relatively to the rear locking surface (3) to open the battery box cover. When the external force exerted on the pushbutton (1) is removed, the pushbutton (1) bounces out of the groove of the rear locking surface (3) under the rebounding force of the spring (2), and extends into the through hole of the battery box cover (4) to limit the horizontal movement of the battery box cover (4) relatively to the rear locking surface (3). With the structure, the door lock battery can be conveniently replaced, thereby improving the safety performance.

Description

The opening/closing device of door lock battery case lid

Technical field

The utility model relates to a kind of parts of lock, particularly a kind of opening/closing device of door lock battery case lid.

Background technology

At present, the opening/closing device of door lock battery case lid, in existing technology, generally employing instrument on/off operation of assisting or simple sliding cover type ON/OFF not only influence attractive in appearancely, and are waiting to improve aspect convenient, security performance.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned defective, a kind of opening/closing device of changing convenient, the safe door lock battery case lid of battery to be provided.

In order to achieve the above object, the technical solution of the utility model is as follows:

The opening/closing device of door lock battery case lid, comprise button 1., spring 2., the back locking face 3., battery case lid 4.; Button 1. and the back locking face spring is housed 2. between 3., battery case lid has a borehole jack to be contained in button on 4. 1. to go up, 1. form position limiting structure with button, and by 3. draw-in

groove

31,34 spiral-locks formation one of

stuck point

41,44 and back locking face.

2. spring is not limited to this spring mode with the function that 1. button is realized.

1. button is contained in the locking face groove 3. of back, and 2. 1. button tighten spring by external force and be pressed in the back locking face groove 3., and battery case lid is 3. move left and right of back locking face relatively 4., and then opens battery case lid; When button external force was 1. cancelled, button ejected from back locking face groove 3., and puts in the battery case lid through hole 4. 1. under spring bounce-back 2., and the limit battery lid is back locking face move left and right 3. relatively 4..

Owing to adopted said structure, the replacing of door lock battery is very convenient, has improved security performance, and simple in structure, is easy to produce.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

groove

31,34 spiral-locks formation one of

stuck point

41,44 and back locking face.

By shown in Figure 1: the back locking face has

stuck point

31,34 on 3., and corresponding battery case lid draw-in

groove

41,44 4. respectively, and 4. spiral-lock is when 3. the back locking face is gone up when battery case lid, and 31

block

41,34 blocks 44, prevents that 3. 4. battery case lid upwards break away from the back locking face; Button has on 1. rib 13 and spring upper surface 21 2. to offset, 3. back locking face has rib 35 and spring lower surface 22 2. to offset, 1. button has left and right sides silhouette edge 11,12,3. back locking face has groove limit, the left and

right sides

32,33,4. battery case lid has through hole limit, the left and

right sides

42,43, and wherein 1. 4. locking face 3. left groove limit 32, corresponding respectively back, left profile limit 11 and battery case lid have left through hole limit 42 to button; 4. corresponding respectively locking face 3. right groove limit 33, back of the 1. right silhouette edge 12 of button and battery case lid have right through hole limit 43;

Press Fig. 2, shown in Figure 3: under the positive pressure of external force, 1. button tightens spring and withdraws from the through hole of battery case lid through hole limit, the left and

right sides

42,43 formation 4. fully, in the groove that locking face groove limit, the left and

right sides

32,33 3. forms after the indentation, button this moment left and right sides silhouette edge 11,12 and battery case lid through hole limit, the left and

right sides

42,43 4. 1. do not offset fully, battery case lid 4. can be fully with respect to button 1. with 3. move left and right of back locking face, i.e. 4. detachable of battery case lid.

As shown in Figure 2, when the external force effect of malleation is cancelled, button is 1. under spring bounce-back 2., from 3. left and right sides groove limit 32 of locking face, back, eject in 33 grooves that form, and put in 4. left and right sides through hole limit 42 of battery case lid, in 43 through holes that form, this moment button left profile limit 11 1. respectively with the 3. left groove of back locking face limit 32, battery case lid left through hole limit 42 4. offsets, button right silhouette edge 12 1. respectively with locking face 3. right groove limit, back 33, battery case lid right through hole limit 43 4. offsets, back locking face has stuck point 31 on 3., 34 respectively with battery case lid draw-in groove 41 4., 44 offset, and promptly 3. 1. 4. battery case lid can not move up and down with the back locking face by relative key.
