Embodiment 1

[0018] refer to Figure 1-2 , a lock that can prevent the door body from being closed by mistake, including a door body 1, a laterally arranged chute 2 is opened on the side of the door body 1, and a lock tongue 3 is slidably connected to the inside of the chute 2, and the lock tongue 3 is connected to the chute 2 The first spring 4 is fixedly connected between the inner walls, and a groove is provided in the middle of the deadbolt 3, and a block 4 is inserted in the groove, and a telescopic spring for use with the block 4 is correspondingly provided on the inner wall of the chute 2. The groove 5, the end of the clamp block 4 away from the groove is located inside the telescopic groove 5 and is fixedly connected with a first magnetic slider 6, and the first magnetic slider 6 is slidably connected with the inner wall of the telescopic groove 5, and the first magnetic slider 6 is away from the inner wall of the telescopic groove 5. A second spring 7 is fixedly connected between ...

Embodiment 2

[0022] refer to Figure 3-4 The difference between this embodiment and Embodiment 1 is that the trigger mechanism includes a pull cord 27 fixedly connected to the back of the first magnetic slider 6, and two turrets 19 are vertically fixed on the back of the door body 1, two The turret 19 is connected with a horizontally arranged second rotating shaft 20 through and rotating together, and a winding wheel 21 is fixedly sleeved on the second rotating shaft 20, and the end of the stay cord 27 away from the first magnetic slider 6 is supported by the spring 7 After passing through the center, it extends to the outside of the back of the door body 1 and is wound on the winding wheel 21. The two ends of the second rotating shaft 20 are also fixedly connected with the spring 22 and the first bevel gear 23 respectively. The back of the door body 1 is also vertical A connecting rod 24 is rotatably connected, and a second bevel gear 25 is fixedly sleeved on the connecting rod 24, and th...

Abstract

The invention discloses a lock capable of preventing a door body from being mistakenly closed. The lock capable of preventing the door body from being mistakenly closed comprises the door body, a transversely-arranged sliding groove is formed in the side edge of the door body, a spring bolt is connected into the sliding groove in a sliding mode, a first spring is fixedly connected between the spring bolt and the inner wall of the sliding groove, a groove is formed in the middle of the spring bolt, a clamping block is inserted into the groove, a telescopic groove used in cooperation with the clamping block is further correspondingly formed in the inner wall of the sliding groove, the end, away from the groove, of the clamping block is located in the telescopic groove and fixedly connected with a first magnetic sliding block, the first magnetic sliding block is in sliding connection with the inner wall of the telescopic groove, and a second spring is fixedly connected between the side wall of the side, away from the clamping block, of the first magnetic sliding block and the inner wall of the telescopic groove. Transmission is conducted through wind power generated when the door bodyis blown by strong wind to be closed, so that the spring bolt automatically stretches out to prevent the door body from being closed; and the situation that a house owner is locked outside the door can be effectively avoided, the collision strength of the door body can be reduced, and use is more convenient.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a lock that can prevent a door body from being closed by mistake. Background technique [0002] Although the existing door locks can fix the deadbolt inside the door body to prevent the door from closing suddenly, it often happens that the door is closed due to sudden wind in daily life, and the owner is locked out of the door. This situation not only easily affects daily life, but also the door body is easily damaged due to violent collision with the door frame, causing unnecessary economic losses. [0003] For this reason, we have proposed a kind of lockset that can prevent door body from closing by mistake. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the house door is often closed due to sudden wind in daily life in the prior art, and the house owner is locked outside the door, and proposes a lock that can prevent ...
