Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a locking device for a push-type fireproof lock. Background Technology

[0002] A push-type fireproof lock is a type of lock specifically designed to improve the fire safety of buildings. Its main feature is that it locks and unlocks through a push-type mechanism. Unlike traditional rotary or pull locks, push-type fireproof locks are simpler and more effective to operate, allowing for quick opening in emergencies. However, traditional push-type fireproof locks often have a problem: the push-unlock mechanism is relatively flexible to facilitate rapid unlocking. This can easily lead to accidental opening of the lock. Furthermore, to prevent accidental opening, push-type fireproof locks are usually deadbolted. However, deadbolted locks are difficult to open, and unlocking requires first de-locking, which is cumbersome and prevents automatic locking after use, thus reducing their effectiveness.

[0003] Therefore, it is necessary to develop a locking device for a push-type fireproof lock. Utility Model Content

[0004] The purpose of this utility model is to provide a locking device for a push-type fireproof lock to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a locking device for a push-type fireproof lock, comprising a push-type fireproof lock, wherein a guide groove is provided on one side of the surface of the push-type fireproof lock, and a T-shaped post is provided on one side of the top of the push-type fireproof lock;

[0006] A locking seat is installed at the top center of the push-to-lock fireproof lock.

[0007] Preferably, a push-type fireproof lock is installed on the other side of the top of the push-type fireproof lock, and a lock tongue is installed on one outer wall of the push-type fireproof lock.

[0008] Preferably, a deadbolt is provided on the other side of the top of the push-type fireproof lock, and the deadbolt is located on the left side of the push-type base.

[0009] Preferably, a collar is rotatably connected to the center of the outer wall of the T-shaped column, and a connecting rope is provided on the outer wall of the collar, with a limit ring at one end of the connecting rope.

[0010] Preferably, a guide block is provided below the inner wall of the locking seat, the outer wall of the guide block is slidably connected to the inner wall of the guide groove, and a fixing plate is provided on one side of the inner top of the locking seat.

[0011] Preferably, a positioning seat is installed on one outer wall of the fixing plate, and a guide post is installed on the other outer wall of the fixing plate, with a guide plate slidably connected to one side of the outer wall of the guide post.

[0012] Preferably, the bottom of the guide plate is fixedly connected to the top of the push-to-open fireproof lock, and a limit plate is installed at one end of the guide column.

[0013] Preferably, a spring is provided on the other side of the outer wall of the guide post, a push-pull plate is installed on the top of the locking seat, and a limit post is provided on one side of the outer wall of the push-pull plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By sliding the locking seat within the guide groove of the push-type fireproof lock via a guide block, and installing a positioning seat on one side of the fixing plate of the locking seat, the locking seat can be moved horizontally to the left or right, simultaneously moving the positioning seat. By sliding the guide post on the fixing plate into the guide plate of the push-type fireproof lock, and installing a spring on the outer wall of the guide post, the spring's elastic reaction force pushes the positioning seat below the push-type fireproof lock, thus achieving a limited locking mechanism for the push-type fireproof lock. This minimizes the risk of the push-type fireproof lock being too flexible and easily pushed in or unlocked accidentally. Simultaneously, when the push-to-unlock fireproof lock needs to be unlocked, simply push the push-pull plate outward until the positioning seat moves away from the push-to-unlock seat, then push the push-to-unlock seat to achieve the effect of unlocking the fireproof lock. The operation is simple; one pull and one push is all it takes to unlock the fireproof lock. After the locking seat is pulled and released, the spring can reset the positioning seat, thus achieving a second locking and limiting effect on the push-to-unlock seat. This achieves a self-locking effect for the push-to-unlock fireproof lock, eliminating the need for a deadbolt. This avoids the situation where the fireproof lock in a deadbolt state needs to be unlocked before each unlocking, effectively improving the usability of the push-to-unlock fireproof lock.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides the following technical solution: a locking device for a push-type fireproof lock, please refer to [link / reference]. Figures 1-4 The fireproof lock includes a push-type fireproof lock 1. A guide groove 101 is provided on one side of the surface of the push-type fireproof lock 1. A push-type seat 102 is installed on the other side of the top of the push-type fireproof lock 1. A lock tongue 103 is installed on one side of the outer wall of the push-type fireproof lock 1. A deadbolt 104 is provided on the other side of the top of the push-type fireproof lock 1. The deadbolt 104 is located to the left of the push-type seat 102. A T-shaped post 2 is provided on one side of the top of the push-type fireproof lock 1. A collar 201 is rotatably connected to the center of the outer wall of the T-shaped post 2. A connecting rope 202 is provided on the outer wall of the collar 201. A limit ring 203 is provided at one end of the connecting rope 202.

[0023] A locking seat 3 is installed at the top center of the push-type fireproof lock 1. A guide block 301 is provided on the lower inner wall of the locking seat 3. The outer wall of the guide block 301 is slidably connected to the inner wall of the guide groove 101. A fixing plate 302 is provided on one side of the top of the locking seat 3. A positioning seat 303 is installed on one side of the outer wall of the fixing plate 302. The locking seat 3 is slidably placed in the guide groove 101 on the push-type fireproof lock 1 by the guide block 301. The positioning seat 303 is provided on one side of the fixing plate 302 on the locking seat 3, so that it pushes the locking seat 3 to move horizontally to the left or right, and can simultaneously drive the positioning seat 303 to move. A guide post 304 is installed on the other side of the outer wall of the fixing plate 302. The outer wall of the guide post 304 slides... A guide plate 305 is connected, with its bottom fixedly connected to the top of the push-to-open fireproof lock 1. A limit plate 306 is installed at one end of the guide post 304, and a spring 307 is provided on the other side of the outer wall of the guide post 304. A push-pull plate 308 is installed on the top of the locking seat 3, and a limit post 309 is provided on one side of the outer wall of the push-pull plate 308. The guide post 304 on the fixing plate 302 is slidably connected to the guide plate 305 on the push-to-open fireproof lock 1, and the spring 307 is fitted on the outer wall of the guide post 304. Based on the elastic reaction force of the spring 307, the spring 307 pushes the positioning seat 303 to be below the push seat 102 on the push-to-open fireproof lock 1, thus preventing the push seat 102 from being pushed in. This system achieves a limiting and locking mechanism for the push-type fireproof lock 1, minimizing the possibility of the push seat 102 on the fireproof lock 1 being too flexible and easily pushed in and unlocked accidentally. When the fireproof lock 1 needs to be unlocked by pushing, simply push the push-pull plate 308 outwards until the positioning seat 303 moves away from the push seat 102, then push the push seat 102 in to unlock the fireproof lock 1. The operation is simple; a pull and a push are all it takes to unlock the fireproof lock 1. Furthermore, after the locking seat 3 is pulled and released, the spring 307 can reset the positioning seat 303, thus achieving a second locking and limiting mechanism for the push seat 102. This achieves a self-locking effect for the push-type fireproof lock, eliminating the need for reverse locking of the fireproof lock 1. To minimize the need to unlock the push-type fireproof lock 1 from its deadbolt state, one end of the connecting rope 202 is rotatably connected to the outer wall of the T-shaped post 2 on the push-type fireproof lock 1 via a collar 201. When the locking seat 3 is released, simply pull the locking seat 3 to a certain position, then pull the limiting ring 203 on the connecting rope 202, which is fitted onto the limiting post 309 on the push-pull plate 308, thus limiting the position of the locking seat 3. Similarly, when the push-type fireproof lock 1 needs to be locked, simply disengage the limiting ring 203 from the limiting post 309, and the spring 307 inside the locking seat 3 will reset and push the positioning seat 303 to move below the push-type seat 102.

[0024] Working principle: When using this utility model, the locking seat 3 is slidably set in the guide groove 101 on the push-type fireproof lock 1 by the guide block 301, and a positioning seat 303 is set on one side of the fixing plate 302 on the locking seat 3, so that it pushes the locking seat 3 to move horizontally to the left or right, which can simultaneously drive the positioning seat 303 to move. By sliding the guide post 304 on the fixing plate 302 into the guide plate 305 on the push-type fireproof lock 1, and a spring 307 is fitted on the outer wall of the guide post 304, the spring 307 has elasticity. The reaction force causes the spring 307 to push the positioning seat 303 below the push seat 102 on the push-to-open fireproof lock 1, thus preventing the push seat 102 from being pushed in. This achieves a limiting and locking effect on the push-to-open fireproof lock 1, minimizing the possibility of the push seat 102 being too flexible and easily pushed in and unlocked. Simultaneously, when the push-to-open fireproof lock 1 needs to be unlocked, simply push the push-pull plate 308 outwards until the positioning seat 303 moves away from the push seat 102, allowing the push seat 102 to be pushed in, achieving the unlocking effect of the push-to-open fireproof lock 1. The operation is simple; a pull and a push are all it takes to unlock the push-type fireproof lock 1. After the locking seat 3 is pulled and released, the spring 307 resets the positioning seat 303, thus achieving a second locking and limiting effect on the push seat 102. This achieves a self-locking effect for the push-type fireproof lock, eliminating the need for a reverse locking mechanism on the push-type fireproof lock 1. This avoids the situation where the push-type fireproof lock 1 needs to be unlocked before unlocking, as it is in a reverse-locked state. One end of the connecting rope 202 is rotatably connected to the push-type fireproof lock 1 via a collar 201. At the outer wall of the T-shaped column 2, when the locking seat 3 is released from its locking position, simply pull the locking seat 3 to a certain position, then pull the limiting ring 203 on the connecting rope 202, which is fitted onto the limiting post 309 on the push-pull plate 308. This will limit the position of the locking seat 3. Similarly, when the flat-push fireproof lock 1 needs to be locked, simply disengage the limiting ring 203 from the limiting post 309. The spring 307 inside the locking seat 3 will then reset and push the positioning seat 303 to move below the flat-push seat 102. This effectively improves the performance of the flat-push fireproof lock.
