Description

Technical Field

[0001] This utility model relates to the field of elevator installation and maintenance technology, specifically to an elevator lock that is easy to install. Background Technology

[0002] An elevator's structure consists of an elevator car on one side and a counterweight on the other. The elevator machine uses steel cables to move the car and counterweight vertically along the elevator guide rails. As elevators age, some wear parts need replacement (such as steel cables, car return pulleys, and bearings). Repairing or replacing these parts requires lifting the car and supporting the counterweight in the pit, suspending the steel cables in the air for replacement. Because the hook is located in the elevator machine room, lifting the car is limited to the highest floor. The counterweight is supported by steel pipes in the pit, but due to the length, weight, and transportation inconvenience of the pipes, the counterweight is limited to the lowest floor. Currently, the biggest problem in elevator maintenance is the inability to stop the car and counterweight at arbitrary positions, preventing operators from standing above the car to perform work. Therefore, an auxiliary tool capable of reliably stopping the elevator is needed.

[0003] For example, an elevator guide rail lock disclosed in announcement number "CN219823328U" can effectively and quickly achieve reliable stopping and locking of the elevator for maintenance. It has a simple overall structure, is easy and quick to install and use, and has low manufacturing cost.

[0004] However, during use, before connecting the housing to the anti-slip plate, the clamp handle needs to be placed in the adjustment slot of the housing. During installation, the clamp handle cannot be restricted, which means that after the clamp handle is placed, when connecting the housing to the anti-slip plate, the clamp handle may fall off, which has certain drawbacks. In addition, after a period of use, the clamp handle is prone to slight wear. If the staff does not replace it in time, it may easily lead to the inability to play an effective locking function, thus causing danger. Therefore, we propose an elevator lock that is easy to install. Utility Model Content

[0005] The purpose of this invention is to provide an elevator lock that is easy to install, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elevator lock that is easy to install, comprising a stop plate, a housing, a clamp handle, and a T-shaped guide rail, wherein the housing and the clamp handle are provided with an auxiliary assembly structure and abutment device for initially restricting the clamp handle;

[0007] The abutment device includes:

[0008] The contact arc plate is used to apply a force to the clamp handle to move towards the T-shaped guide rail through the contact triangle block, so that the clamp handle and the T-shaped guide rail are always in contact.

[0009] The movable plate is used to push the opposing arc plate to swing via a push rod.

[0010] Preferably, the housing has a through groove and a through hole on the side near the anti-slip plate, and the housing has a cavity inside.

[0011] Preferably, the abutting arc plate is rotatably mounted on the inner wall of the cavity, the movable plate passes through the through groove and is slidably connected to the through groove, a support spring is fixed at the bottom of the movable plate, the end of the support spring away from the movable plate is fixed to the inner side of the through groove, a push rod is fixed at the bottom of the movable plate, and the triangular block is fixed on the side of the pliers handle near the housing. When the pliers handle is pulled downward, the pliers handle first abuts against the movable plate, pushing the movable plate downward. The movable plate can then push the abutting arc plate through the push rod, causing the abutting arc plate to rotate at the position connected to the cavity. The abutting arc plate abuts against the triangular block, pushing the pliers handle to the side closer to the T-shaped guide rail, so that the pliers handle and the T-shaped guide rail are firmly in contact. This ensures that the pliers handle abuts against the T-shaped guide rail more tightly as it moves downward, avoiding the pliers handle from failing to lock effectively and causing danger when it is slightly worn after long-term use.

[0012] Preferably, the auxiliary assembly structure includes a slot, which is located on the side of the housing near the T-shaped guide rail. A plug is fixed on the side of the pliers near the housing, and the plug is inserted into the slot. When assembling the device as a whole, the plug on the pliers is inserted into the slot on the housing to initially limit the pliers, which can effectively prevent the pliers from falling off when connecting the housing and the anti-slip plate.

[0013] Preferably, the bottom of the clamp handle is provided with a lifting ring for connecting to the hooks at the four corners of the elevator.

[0014] Compared with the prior art, this utility model provides an elevator lock that is easy to install and has the following advantages:

[0015] 1. This easy-to-install elevator lock, through its designed abutment device, ensures that when the clamp handle is pulled downwards, it first abuts against the moving plate, pushing the moving plate downwards. The moving plate then pushes the abutment arc plate via a push rod, causing the abutment arc plate to rotate to the position connected to the cavity. The abutment arc plate then abuts against the triangular block, pushing the clamp handle towards the side closer to the T-shaped guide rail. This ensures that the clamp handle and the T-shaped guide rail are firmly in contact as the clamp handle moves downwards, resulting in a tighter contact. This prevents the clamp handle from becoming slightly worn after prolonged use and failing to provide effective locking, thus avoiding potential dangers.

[0016] 2. This easy-to-install elevator lock, through its auxiliary assembly structure, allows for initial positioning of the clamp handle by inserting the insert block on the clamp handle into the slot on the housing during the overall assembly of the device. This effectively prevents the clamp handle from falling off when connecting the housing to the anti-slip plate. Attached Figure Description

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: an elevator lock that is easy to install, including a stop plate 1, a housing 2, a clamp handle 5 and a T-shaped guide rail 6. The housing 2 and the clamp handle 5 are provided with an auxiliary assembly structure 3 and an abutment device 4 for initially restricting the clamp handle 5. The abutment device 4 includes: an abutment arc plate 41, a triangular block 42, a moving plate 43, a push rod 44 and a support spring 45.

[0024] The housing 2 has a through groove 7 and a through hole 8 on the side near the anti-slip plate 1. The housing 2 has a cavity 9 inside. The bottom of the clamp handle 5 is provided with a lifting ring 10 for connecting with the hooks at the four corners of the elevator.

[0025] The contact plate 41 is rotatably mounted on the inner wall of the cavity 9. The movable plate 43 passes through the through groove 7 and is slidably connected to the through groove 7. A support spring 45 is fixed to the bottom of the movable plate 43. The end of the support spring 45 away from the movable plate 43 is fixed to the inside of the through groove 7. A push rod 44 is fixed to the bottom of the movable plate 43. A triangular block 42 is fixed to the side of the clamp handle 5 near the housing 2. When the clamp handle 5 is pulled downward, the clamp handle 5 first contacts the movable plate 43, pushing the movable plate 43 downward. The movable plate 43 can push the abutting arc plate 41 through the push rod 44, so that the abutting arc plate 41 rotates to the position connected with the cavity 9. The abutting arc plate 41 abuts against the triangular block 42, pushing the clamp handle 5 to move closer to the T-shaped guide rail 6, so that the clamp handle 5 and the T-shaped guide rail 6 are firmly in contact. The more the clamp handle 5 moves downward, the tighter the contact between the clamp handle 5 and the T-shaped guide rail 6 becomes, avoiding the possibility that the clamp handle 5 will not be able to effectively lock when it is slightly worn after long-term use, thus preventing danger.

[0026] The auxiliary assembly structure 3 includes a slot 31, which is located on the side of the housing 2 near the T-shaped guide rail 6. A plug 32 is fixed on the side of the clamp handle 5 near the housing 2. The plug 32 is inserted into the slot 31. When assembling the whole device, the plug 32 on the clamp handle 5 is inserted into the slot 31 on the housing 2 to initially limit the clamp handle 5. This can effectively prevent the clamp handle 5 from falling off when the housing 2 is connected to the anti-slip plate 1.

[0027] In this utility model, when the elevator needs to be stopped during elevator maintenance, the insert block 32 on the clamp handle 5 is first inserted into the slot 31 on the housing 2 to initially limit the clamp handle 5. The anti-slip plate 1 is placed on the back of the T-shaped guide rail 6, and the housing 2 and the anti-slip plate 1 are spliced ​​together and fastened with bolts. The hooks connecting the four corners of the elevator are hung on the lifting ring 10. When the clamp handle 5 is pulled downward, the clamp handle 5 first abuts against the moving plate 43, pushing the moving plate 43 downward. The movable plate 43 can push the abutting arc plate 41 through the push rod 44, so that the abutting arc plate 41 rotates to the position connected with the cavity 9. The abutting arc plate 41 abuts against the triangular block 42, pushing the clamp handle 5 to move closer to the T-shaped guide rail 6, so that the clamp handle 5 and the T-shaped guide rail 6 are firmly in contact. The more the clamp handle 5 moves downward, the tighter the contact between the clamp handle 5 and the T-shaped guide rail 6 becomes. This avoids the clamp handle 5 from failing to lock effectively when it is slightly worn after long-term use, which could lead to danger.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
