Problems solved by technology

[0003] In view of the above problems, the present invention provides a ground hook lock anti-sliding door structure. In the locked state, when the controller cannot accurately judge the state of the ground hook lock due to misoperation by the operator, the motor drives the door body to move upward. In the event that the ground hook lock pulls the rolling door or is buried underground, it can improve the safety of the rolling door during use

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings.

[0022] Such as Figure 1 to Figure 3 As shown, the anti-zipper hook lock includes a lock housing 1 , a horizontal pull piece 2 , a locking piece 3 , a limiting piece 4 and a lock tongue 5 . The horizontal pull piece 2 can move relative to the lock housing 1, the locking piece 3, the limit piece 4 and the lock tongue 5 are rotatably connected to the lock casing 1, and the horizontal pull piece 2 is provided with a first driving part 21 and a second driving part 22. Move the horizontal pull member 2 so that the first driving part 21 and the second driving part 22 are in contact with the locking part 3 and the limiting part 4 respectively, so that the locking part 3 and the limiting part 4 are in the open position ( figure 2 shown) and the locked position ( figure 1 shown) to rotate between. The locking part 3 is provided with a first protruding par...

Abstract

The invention provides an anti-pulling door structure of a ground hook lock. The structure comprises a lock shell, a transverse pulling piece, a locking piece, a limiting piece and a spring bolt. Thetransverse pulling piece can move relative to the lock shell; the locking piece, the limiting piece and the spring bolt are connected to the lock shell in a rotating mode. A first driving part matchedwith the locking piece , and a second driving part matched with the limiting piece are arranged on the transverse pulling piece; a first protruding part is arranged on the locking piece, a second protruding part is arranged on the limiting piece, the structure further comprises a driving piece for driving the limiting piece to rotate towards one side of the first protruding part, and the ground hook lock can prevent force generated by a motor from damaging a roller shutter door body and the ground.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a ground hook lock anti-sliding door structure. Background technique [0002] by figure 1 Take the structure of the middle part as an example. The lock casing of the existing ground hook lock is provided with a locking piece, a limit piece and a dead bolt. After the position parts are separated, the locking part still limits the dead bolt. At this time, the movement of the dead bolt will trigger the micro switch to realize the alarm, and at the same time, avoid damage to the structure of the parts in the lock body. When the key is unlocked, the slats in the lock housing drive the separation of the locking part, the limiting part and the deadbolt. When the key is closed, the slats are gradually separated from the locking part and the limiting part, and the locking part and the limiting part are reset to lock. Position, and cooperate with the lock tongue to achieve locking. In rea...
