DETAILED DESCRIPTION

[0016] The embodiments of the utility model are described in detail below with reference to the drawings. EMBODIMENT

[0017] As shown in Figure 1 and 2 The utility model provides a kind of automatic lock tongue multidirectional adjustment lock, specifically including lock body 1, first telescopic block 2, guide plate 3, sliding pipe 5, lock tongue 6, spring 7, positioning block 8 and protruding block 9;

[0018] Among them, the first telescopic block 2 is slidably arranged on the right side of the lock body 1, and the right side of the first telescopic block 2 is arc-shaped, for pushing the lock tongue 6 out to lock the lock;

[0019] Among them, the arc-shaped guide plate 3 is fixedly arranged at a certain distance from the right side of the lock body 1, the middle part of the guide plate 3 penetrates a long strip-shaped guide groove 4, for guiding the lock tongue 6;

[0020] Among them, a sliding tube 5 is slidably provided in the guide groove 4, and a locking tongue 6 is slidably provided in the sliding tube 5. The left arc surface of the locking tongue 6 contacts the right arc surface of the first telescopic block 2. A spring 7 is connected between the locking tongue 6 and the lock body 1 to achieve the purpose of adjusting the angle of the locking tongue.

[0021] The upper and lower guide plates 3 of the sliding tube 5 are provided with positioning blocks 8 fixed to the outside by screws, and the upper and lower guide plates 3 of the sliding tube 5 are provided with protrusions 9 fixed inside, with screws connected to the protrusions 9 for fixing the position of the locking tongue 6.

[0022] In this invention, when the door frame and door body are not flush, although the door can be closed, the bolt 6 of a common lock is difficult to insert into the lock hole. In this case, the worker can loosen the screws on the positioning block 8, causing it to move. Since the sliding tube 5 can slide on the guide plate 3 through the guide groove 4, and the guide plate 3 is arc-shaped, sliding the sliding tube 5 changes its angle, thus changing the direction of the bolt 6 within it. The worker can then adjust the position of the sliding tube 5 on the guide plate 3 to allow the bolt 6 to enter the lock hole. This prevents the bolt 6 from failing to enter the lock hole when the door frame or door body deforms or sinks. Tighten the screws on the positioning block 8 to fix the sliding tube 5, thus fixing the direction of the latch 6. In addition, by setting the lock body 1 to the locked state, the first telescopic block 2 extends. Since the latch 6 can slide inside the sliding tube 5 and one end is in contact with the first telescopic block 2, and since the contact surfaces of the first telescopic block 2 and the latch 6 are both arc-shaped, even if the angle between the first telescopic block 2 and the latch 6 changes, i.e., the angle between the latch 6 and the lock body 1 changes, the latch 6 can still extend. When the lock body 1 is set to the unlocked state, the first telescopic block 2 retracts, and the latch 6 is pulled back by the spring 7 connecting the lock body 1 and the latch 6, moving the latch 6 away from the keyhole, thus allowing the latch 6 to be used normally. Example

[0023] like Figure 2 As shown, based on embodiment 1, it further includes a screw 10 and a second telescopic block 11. The screw 10 is rotatably provided on the inner side of the front end of the locking tongue 6, and the outer side of the screw 10 has a groove for controlling rotation. The second telescopic block 11 is slidably provided on the front end of the locking tongue 6, and the second telescopic block 11 has a through hole in the middle that cooperates with the screw 10.

[0024] The worker adjusts the length of the lock tongue 6 by rotating the screw rod 10, and the second telescopic block 11 rotates along the inner side wall of the front end of the lock tongue 6, and the second telescopic block 11 is extended as the extension of the lock tongue 6 by the forward rotation of the screw rod 10, and the second telescopic block 11 is retracted as the contraction of the lock tongue 6 by the reverse rotation of the screw rod 10, so that the length of the lock tongue 6 can be controlled, and the stability and durability of the door lock are affected by the too long or too short lock tongue 6, so the length of the lock tongue 6 should be adjusted by the screw rod 10 after the angle of the lock tongue 6 is adjusted.

[0025] As shown in Figure 2 , on the basis of example 1, it further comprises a pad 12 fixed between the positioning block 8 and the guide plate 3.

[0026] The pad 12 provides greater friction, and the positioning block 8 can provide better positioning effect, preventing the lock tongue 6 from shifting during daily use.

[0027] As shown in Figure 1 and Figure 2 , on the basis of example 1, it further comprises a lubricating groove 13 opened on the upper and lower sides of the lock tongue 6.

[0028] By setting the lubricant in the lubricating groove 13, the friction of the lock tongue 6 in the sliding pipe 5 can be reduced, and the sliding of the lock tongue 6 is more smooth.

[0029] As shown in Figure 1 and Figure 2 , on the basis of example 1, it further comprises a plug cover 14, and the second telescopic block 11 is provided with a through hole on the front side and the plug cover 14 is arranged outside the through hole.

[0030] The plug cover 14 can protect the connection between the screw rod 10 and the second telescopic block from entering impurities.

[0031] The above is only an embodiment of the present application and is not used to limit the present application. Any equivalent replacement within the principles of the present application should be included in the protection scope of the present application. The contents not described in detail in the present application belong to the existing technology known to the technical personnel in the field.
