The utility model further sets: the inner core of the lock tongue is in the shape of a cylinder, and is adapted to the cavity of the lock tongue outer casing.

The utility model further provides that: the abutment part is in a circular shape, and the diameter of the abutment part is the same as the outer diameter of the lock tongue outer casing, so that the abutment part is flush with the lock tongue outer casing.

The utility model further provides that: the other end of the inner core of the deadbolt is provided with a connection part, and the installation frame is provided with a connection hole, and the connection part is riveted to the installation frame through the connection hole.

The utility model is further provided with: four deadbolts are installed side by side on the installation frame.

The utility model provides another solution: a lock body, including a lock case, the lock case contains an anti-saw lock bolt structure, the lock bolt is slidably arranged on the lock case through the mounting frame, and the push in the lock case The plate pushes the mounting bracket so that the deadbolt protrudes from the lock housing.

The utility model has beneficial effects: the lock tongue includes a lock tongue inner core and a cylinder-shaped lock tongue jacket; the lock tongue jacket is sleeved on the lock tongue inner core, and the lock tongue inner core is wrapped in the cavity of the lock tongue jacket Inside the body, the inner core of the deadbolt is protected in the outer casing of the deadbolt; when the person outside the door pulls the saw back and forth to cut off the deadbolt through the saw, the outer casing of the deadbolt will rotate relative to the inner core of the deadbolt, so that the saw teeth There will be slippage on the outer wall of the deadbolt jacket, so that the outside personnel cannot saw through the deadbolt jacket to further saw off the inner core of the deadbolt, which better protects the structure of the deadbolt and the door lock; it is very good To the anti-saw effect of the lock tongue, improve the safety performance of the door lock.

detailed description

Referring to accompanying drawings 1 to 6, the anti-saw lock tongue structure and lock body of the present invention will be further described in detail.

Embodiment 1: An anti-saw lock tongue structure, including a lock tongue 1 and a mounting bracket 2 for installing the lock tongue 1; the lock tongue 1 includes a cylinder-shaped lock tongue inner core 11 and a cylinder-shaped lock The tongue outer cover 12, the dead bolt inner core 11 of the dead bolt 1 is adapted to the cavity 121 of the dead bolt outer cover 12; In the cavity 121 of the tongue cover 12, the lock tongue inner core 11 is protected in the lock tongue cover 12, and the lock tongue cover 12 can rotate relative to the lock tongue inner core 11; one end of the lock tongue inner core 11 is provided with The abutting portion 111 , the abutting portion 111 abuts against the lock tongue outer shell 12 .

When people outside the door pull the saw back and forth to saw the deadbolt 1 through the saw, the deadbolt cover 12 will rotate relative to the deadbolt inner core 11, so that the serrations of the saw will slip on the outer wall of the deadbolt cover 12 Therefore, the personnel outside the door cannot further cut off the deadbolt inner core 11 by sawing through the deadbolt outer cover 12, which better protects the deadbolt 1 and the structure of the door lock; Function, improve the safety performance of the door lock.

In order to make the deadbolt cover 12 better protect the deadbolt inner core 11, the abutting portion 111 is in a circular shape, and the diameter of the abutting portion 111 is the same as the outer diameter of the deadbolt cover 12; The other end of the core 11 is provided with a connecting portion 112, and the mounting frame 2 is provided with a connecting hole 21, and the connecting portion 112 is riveted on the mounting frame 2 through the connecting hole 21; part is close to the mounting frame 2, and the other end is close to the abutting part 111, and the abutting part 111 is flush with the bolt cover 12; Dead bolt 1 is better matched with the lock hole on the buckle box.

In order to better lock the door leaf on the door frame, four dead bolts 1 are installed side by side on the mounting frame 2, and the four dead bolts 1 lock the door leaf firmly on the door frame.

The following describes Embodiment 2 in which the anti-sawing bolt structure of Embodiment 1 is applied to the lock body: a lock body includes a lock housing 3, and the lock housing 3 includes the above-mentioned anti-sawing bolt structure, The lock tongue 1 is slidably arranged on the lock case 3 through the installation frame 2, and the push plate 31 in the lock case 3 pushes the installation frame 2 to make the lock tongue 1 protrude from the lock case 3, thereby improving the safety performance of the door lock ; When the four dead bolts 1 were retracted into the lock housing 3, the outer sidewalls of the abutting portions 111 of the four dead bolts 1 were flush with the side plates of the lock housing 3, so as to prevent the dead bolt 1 from colliding with the door frame when closing the door. Better protection of the lock bolt 1; at the same time, the lock bolt cover 12 of the lock bolt 1 is completely stored in the lock shell 3, so as to avoid external force from destroying the shape of the lock bolt cover 12, so that the lock bolt cover 12 can be smoothly rotated and set in the lock bolt On the core 11, it can continue to play the role of anti-saw; at the same time, it makes the appearance of the door lock more beautiful.

The above descriptions are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present utility model all belong to the protection scope of the present utility model. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
