Description

Two-way lock tongue synchronous pop-up locking device

technical field

The invention relates to a safety device for an anti-theft door lock, in particular to a two-way lock tongue synchronous pop-up locking device.

Background technique

At present, the anti-theft locks that the deadbolt automatically pops up when the door is closed are all in the pop-up state when the sliding tongue starts to advance. This structural relationship is easy to damage the deadbolt because the deadbolt is in the pop-up state when it is not aligned with the hole. And produce false lock phenomenon; Also have to increase deadbolt control device outside sliding tongue and deadbolt, will make the structure of lock complicated like this, also increased cost.

Contents of the invention

The object of the present invention is to provide a two-way lock tongue synchronous pop-up locking device which is simple in structure, safe and reliable in use, and only when the sliding tongue pops out, the dead bolt synchronously pops out in order to solve the above technical deficiencies.

In order to achieve the above object, a two-way deadbolt synchronous pop-up locking device designed by the present invention includes a sliding tongue control unit, a deadbolt and upper and lower deadbolt pull plates, and the sliding tongue control unit is provided with a deadbolt release bayonet , the upper and lower lock tongue pull plates are provided with clamping feet corresponding to the lock tongue release bayonet, the slide tongue control unit is linked with the slide plate shifting block, and the slide plate shift block is provided with a lock tongue pop-up bayonet, which is fixedly connected with the lock bolt The slide plate is provided with the slide plate clip corresponding to the ejection bayonet of dead bolt. The sliding tongue control unit may be mainly composed of a two-way movable sliding tongue and a sliding tongue connecting rod. One end of the sliding tongue connecting rod is connected with the bidirectional movable sliding tongue, and the other end penetrates into a fixed tailgate hole. The connecting rod overcoat has stage clip. The two-way movable sliding tongue can be a single-tongue structure or a double-tongue structure. The deadbolt release bayonet may be provided on the sliding bolt link in the sliding bolt control unit. It can also be located on the two-way movable sliding tongue. The upper and lower dead bolt pull plates can be provided with a pull plate push pin, and the slide plate fixedly connected with the dead bolt is provided with a pull plate push groove matched with the pull plate push pin.

A two-way deadbolt synchronous pop-up locking device obtained in the present invention, the lock body can open the door regardless of the left and right and the inward and outward opening, and can automatically enter the sliding tongue position when closing the door, and multiple groups (upper, lower and side) deadbolts can be synchronized automatically. It pops out into a locked state, which is safe and reliable when used, and will not produce false locks. In particular, it solves the problem in the prior art that when the sliding tongue is pressed into the locking tongue, it will spring outwards, resulting in a false lock where the locking tongue is not in place, making the safety lock unsafe.

Detailed ways

The present invention will be further described through the following embodiments in conjunction with the accompanying drawings, but the following embodiments do not limit the content of the present invention.

Example:

As shown in Figure 1, a kind of two-way deadbolt synchronous pop-up locking device described in this embodiment includes a sliding tongue control unit 17, a deadbolt 15 and upper and lower deadbolt pull plates 6, and the sliding tongue control unit 17 is provided with The deadbolt release bayonet 5, the upper and lower deadbolt pull plates 6 are provided with the locking feet 7 corresponding to the deadbolt release bayonet 5, the sliding tongue control unit 17 is linked with the slide plate shifting block 10, and the slide plate shifting block 10 is provided with There is a deadbolt ejection bayonet 11 , and a slide plate 16 fixedly connected with the deadbolt 15 is provided with a slide plate clip 12 corresponding to the deadbolt ejection bayonet 11 . As shown in Figure 1 and Figure 2, the sliding tongue control unit 17 is mainly composed of a two-way movable sliding tongue 1 and a sliding tongue connecting rod 4, one end of the sliding tongue connecting rod 4 is connected with the two-way movable sliding tongue 1, and the other end passes through Insert in the 9 holes of the fixed tailgate, and stage clip 8 is overcoated in sliding tongue connecting rod 4. The sliding tongue 1 can be a double-tongue structure as shown in Figure 2, or a single-tongue structure as shown in Figure 3, and the deadbolt release bayonet 5 can be located in the sliding tongue control unit 17 as shown in Figure 4. Tongue connecting rod 4 on. Also can be located on the two-way movable sliding tongue 1 as shown in Figure 1. In order to make the dead bolt 15 on the side come in and out synchronously with the upper and lower dead bolts, the upper and lower dead bolt pull plates 6 are provided with a pull plate pushing pin 13, and the sliding plate 16 which is fixedly connected with the dead bolt is provided with a pull plate pushing pin. 13 matching pull plate push groove 14.

When the door is closed, no matter whether the lock is located on the left or right of the door, or whether the door is opened inward or outward, as long as the movable sliding tongue 1 collides with the door frame, the movable sliding tongue 1 can be retracted into the lock. The working state is shown in Figure 4 As shown, the sliding tongue connecting rod 4 pushes the slide plate shifting block 10, and the lock tongue pops out of the bayonet 11 to release the slide plate clip 12 on the slide plate 16 fixedly connected to the lock tongue, but because the lock tongue on the slide tongue control unit 17 releases the bayonet 5 lock Lock the clamp feet 7 corresponding to the lock tongue release bayonet 5 on the upper and lower lock tongue pull plates 6, the lock tongue 15 cannot pop out, as shown in Figure 5, when the slide tongue 1 is inserted into the slide tongue hole, press Under the effect of spring 8, it pops up automatically. At this time, the dead bolt release bayonet 5 releases the clamping foot 7, and the dead bolt 15 pops up under the action of spring 18. The cooperation of the push groove 14 impels the upper and lower plates to move upward and downward, so that the three directions of the upper, lower and side sides are synchronously entered into the locked state.
