Background

At present, the sealing requirements of the entrance door are more and more strict, and the sealing is usually carried out by adopting adhesive tapes around, but the adhesive tapes have the characteristic of elastic retraction for a long time, gaps can be generated between the door leaves and the door frame, and the sealing performance of the entrance door is reduced.

The applicant applies for patent number 201920362084.1 in 2019 3 and 21 and the utility model name is mechanical attraction anti-theft lockset, and the application adopts self-suction lock tongue to be linked through a control mechanism in a lock box, so that under the condition of locking a door, the self-suction lock tongue is controlled to extend, the end face of the self-suction lock tongue is higher than other lock tongues, a door leaf and a door frame are compressed, and a gap between the door leaf and the door frame is reduced to realize attraction. However, the control mechanism in the structure is complex, and needs to be linked with the main lock tongue sliding block, so that the structure is complex, the control mechanism occupies the space of the lock box, and each part needs to be redesigned to avoid, so that the manufacturing cost is high.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a lever type self-priming structure of a lock tongue, which moves along with the lock tongue, not only occupies small space, but also has simple triggering structure and good self-priming effect.

In order to solve the problems, the specific technical scheme of the utility model is as follows: a lever type lock tongue self-priming structure is characterized in that a lock tongue sliding block is connected in a lock box in a sliding mode, and a lock tongue on the lock tongue sliding block stretches into or stretches out of a lock body panel of the lock box in a sliding mode; a locking lever is arranged between the surface of the lock tongue sliding block and the inner surface of the adjacent lock box, the outer end part of the locking lever is connected with a self-priming locking block, and the self-priming locking block is positioned in a groove at the corresponding position of the lock tongue; the locking lever is connected with the lock tongue sliding block through a lever elastic structure; the tail end of the locking lever is connected with a shifting plate through a rotating shaft, a shifting block is arranged on the lock box and is triggered by contact with the shifting plate, so that the self-priming lock block ejects out of the lock tongue.

The lever elastic structure is as follows: the lock tongue sliding block is provided with a supporting lug at a position close to the lock body panel, and the supporting lug is movably connected with the locking lever through a rotating shaft; a return spring is arranged in the middle of the locking lever; the self-priming locking piece swings with the rotating shaft of the supporting lug as the center.

The return spring is a coil spring, one end of the coil spring is positioned on the locking lever, and the other end of the coil spring is positioned on the lock tongue sliding block.

One end of the shifting plate is of a double-lug structure and is movably connected with the locking lever through a pin shaft, the other end of the shifting plate is of a flat plate surface, and when the lock tongue extends out of the lock box, the plate surface of the shifting plate is vertically clamped with the shifting block.

The lever type spring bolt self-priming structure of the application adopts the structure, and has the following advantages:

1. the locking lever, the deflector rod and the deflector block structure are adopted, and the deflector rod and the deflector block are driven to form a contact and non-contact structure through the sliding of the deflector rod and the deflector block, so that the fluctuation action of the self-priming deflector rod is realized;

2. because the shifting plate is connected by the rotating shaft, when the shifting plate contacts with the shifting block, the shifting plate is in a vertical state with the shifting block, and when the shifting plate is not contacted with the locking lever, the shifting plate and the locking lever are in a buckling state, so that the shifting plate is used as a triggering structure, the triggering structure is simple, and the space of other structures of the lockset is not occupied;

3. can be transformed in the existing lockset to realize the self-priming function of the lockset.

Detailed Description

In order to further explain the technical scheme of the application, the self-priming lock tongue is described by adopting the structure of the self-priming lock tongue in the main lock tongue, and of course, the self-priming lock tongue can also be applied to any lock point of the oblique lock tongue, the heaven-earth lock tongue and the like to finish the self-priming function of the door.

As shown in fig. 1 to 3, a lever type lock tongue self-priming structure is provided, a main lock tongue slide block 2 is slidably connected in a lock box 1, and a main lock tongue 3 on the main lock tongue slide block 2 is slidably extended into or out of a lock body panel 10 of the lock box 1; a locking lever 4 is arranged between the surface of the main lock tongue sliding block 2 and the inner surface of the adjacent lock box, the outer end part of the locking lever 4 is connected with a self-priming lock block 8, and the self-priming lock block 8 is positioned in a groove at the corresponding position of the main lock tongue 3; the self-priming locking block 8 and the locking lever 4 are manufactured into an integral structure in the normal case; the locking lever 4 is connected with the main lock tongue slide block 2 through a lever elastic structure; the tail end of the locking lever 4 is connected with a poking plate 7 through a rotating shaft, a poking block 9 is arranged on the lock box 1, and the poking block 9 is contacted with the poking plate 7.

The lever elastic structure is as follows: a supporting lug 5 is arranged at the position of the main lock tongue sliding block 2, which is close to the lock body panel 10, and the supporting lug 5 is movably connected with the locking lever 4 through a rotating shaft; a return spring 6 is arranged in the middle of the locking lever 4; the self-priming lock block 8 swings with the rotating shaft of the supporting lug 5 as the center. Wherein the return spring 6 is a coil spring, one end of which is positioned on the locking lever 4 and the other end of which is positioned on the main bolt slider 2.
