Description

Technical Field

[0001] The utility model relates to the technical field of elevator safety doors, in particular to a locking structure for an elevator safety door. Background Art

[0002] During the construction process, a safety door is usually installed in the elevator shaft of the building to prevent accidents. In order to prevent the safety door from opening accidentally during the operation of the elevator, a locking structure is usually installed on the elevator safety door to lock the elevator safety door. The existing locking structure usually consists of a lock hook and a lock seat.

[0003] For example, the utility model application number CN202122088414.2 discloses an elevator door that is easy to observe. Specifically, it includes a first elevator door and a second elevator door. The first elevator door is provided with a door nose, which is provided with multiple sockets. A fixed lock block and a movable lock block are provided inside the sockets, and a spring is provided between the two. Each fixed lock block is positioned differently relative to the sockets. The second elevator door is provided with a door latch, and the door latch is cross-cut with sliding grooves, and a plug is slidably connected to the sliding groove. Through the cooperation between the plug and the different sockets, the function of locking elevator doors with different height differences can be achieved. At the same time, elevator doors with gaps can also be locked, effectively preventing safety hazards caused by elevator door failures.

[0004] However, with regard to the current traditional locking structure, after the staff leaves the safety door, they usually need to manually insert the lock hook into the lock seat to lock the elevator safety door. The operation is rather cumbersome and if the staff forgets to insert the lock hook into the lock seat due to carelessness, the elevator safety door may be accidentally opened, which is dangerous and inconvenient to use. Utility Model Content

[0005] In view of this, the utility model provides an elevator safety door locking structure, which has a connecting rod and a locking block that can automatically lock the elevator safety door when the elevator safety door is closed. During the closing process of the safety door body, as the safety door body closes, the control slide will be pushed to move along the guide slide groove and squeeze the fixed spring. As the control slide slides, the connecting rod will be driven to move, and as the connecting rod moves, it will be disengaged from the connecting socket. After the connecting rod is completely disengaged from the connecting socket, the connecting rod will fall and be inserted into the locking slot under the action of its own gravity, automatically locking the safety door body.

[0006] The utility model provides an elevator safety door locking structure, which specifically includes: a mounting frame; two safety door bodies are symmetrically hinged in the mounting frame; a fixing frame is centrally provided on the upper part of the mounting frame; the two safety door bodies are aligned with the positions of the fixing frame; two groups of guide slides are symmetrically provided in the fixing frame; two mounting slides are symmetrically fixedly connected to the outside of the fixing frame; the two mounting slides are both slidably connected in the mounting frame; the rear part of the fixing frame is symmetrically fixedly connected to two fixing seats; the rear parts of the two safety door bodies are fixedly connected to a locking block; the two locking blocks are aligned with the positions of the fixing frame.

[0007] Optionally, two limit rods are symmetrically slidably connected to the upper part of the mounting rack; the rear parts of the two limit rods are fixedly connected to a connecting spring; the ends of the two connecting springs are fixedly connected to the mounting rack; the front parts of the two limit rods are respectively inserted into the two mounting slides.

[0008] Optionally, a control slide is slidably connected in each of the two groups of guide grooves; a group of fixed springs are fixedly connected to the front of the two control slides; the ends of the two groups of fixed springs are fixedly connected in the fixed frame; the rear end faces of the two control slides are in contact with the front end faces of the two safety door bodies.

[0009] Optionally, the rear parts of the two control slides are fixedly connected to a connecting rod; a locking rod is slidably connected to the two fixing seats; a connecting hole is provided on the outside of the two locking rods; the two connecting rods are respectively inserted into the two connecting holes; a locking slot is provided on the top surface of the two locking blocks; and the two locking slots are respectively aligned with the positions of the two locking rods.

[0010] Optionally, the top surfaces of the two locking rods are fixedly connected to a control rope; the two control ropes are slidably connected in the fixing frame; and the ends of the two control ropes are fixedly connected to a control handle.

[0011] Optionally, the inner sides of the two control handles are fixedly connected to a mounting base; the two mounting bases are fixedly connected to an auxiliary magnet; and the magnetic poles of the two auxiliary magnets are opposite.

[0012] Beneficial effects

[0013] The utility model discloses that when the safety door body is closed, the control slide plate is pushed as the safety door body is closed, and then the connecting rod is disengaged from the connecting socket through a series of transmissions. At this time, the connecting rod falls down and is inserted into the locking slot under the action of its own gravity, and the safety door body is automatically locked, which reduces the waiting time of passengers and goods, improves the running efficiency of the elevator, is simpler and faster to operate, effectively improves the convenience of the locking mechanism, and is more convenient to use.

[0014] When it is necessary to open the safety door body, the staff only needs to pull the control handle on one side so that the control rope pulls the locking rod out of the locking slot. Only then can the safety door body on one side be opened. When it is necessary to open two safety door bodies at the same time, the staff only needs to move the two control handles close to each other. Under the action of the auxiliary magnet, the two control handles will be adsorbed together. At this time, pulling the control handle can release the lock of the two safety door bodies at the same time, effectively improving the versatility of the locking structure.

Unless otherwise specified, the terms used herein have the common meanings in the art. The same reference numerals in the drawings represent the same components.

[0026] Example 1:

[0027] This utility model proposes a locking structure for elevator safety doors. Please refer to Figures 1 to 5 , including: installing rack 1;

[0028] Two safety door bodies 101 are symmetrically hinged inside the mounting frame 1; a fixing frame 102 is centrally arranged on the upper part of the mounting frame 1; the two safety door bodies 101 are aligned with the positions of the fixing frame 102; two sets of guide slots 108 are symmetrically provided inside the fixing frame 102; two mounting slides 103 are symmetrically fixedly connected to the outside of the fixing frame 102; the two mounting slides 103 are both slidably connected to the mounting frame 1; the rear part of the fixing frame 102 is symmetrically fixedly connected to two fixing seats 111; the rear part of the two safety door bodies 101 is fixedly connected to a locking block 106; the two locking blocks 106 are aligned with the positions of the fixing frame 102.

[0029] The upper part of the mounting frame 1 is symmetrically and slidingly connected to two limiting rods 105; the rear parts of the two limiting rods 105 are fixedly connected to a connecting spring 104; the ends of the two connecting springs 104 are fixedly connected to the mounting frame 1; the front parts of the two limiting rods 105 are respectively inserted into the two mounting slides 103.

[0030] A control slide 109 is slidably connected in each of the two groups of guide grooves 108; a group of fixed springs 110 are fixedly connected to the front of the two control slides 109; the ends of the two groups of fixed springs 110 are fixedly connected in the fixed frame 102; the rear end faces of the two control slides 109 are in contact with the front end faces of the two safety door bodies 101.

[0031] A connecting rod 112 is fixedly connected to the rear of the two control slides 109; a locking rod 113 is slidably connected to the inside of the two fixing seats 111; a connecting hole 114 is penetrated through the outside of the two locking rods 113; the two connecting rods 112 are respectively inserted into the two connecting holes 114; a locking slot 107 is provided on the top surface of the two locking blocks 106; the two locking slots 107 are aligned with the positions of the two locking rods 113 respectively.

[0032] The top surfaces of the two locking rods 113 are fixedly connected to a control rope 115; the two control ropes 115 are slidably connected in the fixing frame 102; the ends of the two control ropes 115 are fixedly connected to a control handle 116.

[0033] The specific usage and function of this embodiment: When the locking structure is damaged, the staff only needs to press the limit rod 105 to make the limit rod 105 slide in the mounting frame 1 and squeeze the connecting spring 104. As the limit rod 105 moves, it will be detached from the mounting slide 103. At this time, the staff can remove the fixing frame 102 to replace the locking structure. In the process of closing the safety door body 101, as the safety door body 101 closes, the control slide 109 is pushed, so that the control slide 109 moves along the guide slot 108 and squeezes the fixing spring 110. As the control slide 109 slides, the connecting rod 112 is driven to move. The movement of the connecting rod 112 will cause it to disengage from the connecting hole 114. After the connecting rod 112 is completely disengaged from the connecting hole 114, the connecting rod 112 will fall and be inserted into the locking slot 107 under the action of its own gravity, automatically locking the safety door body 101. When the safety door body 101 needs to be opened, the staff only needs to pull the control handle 116 on one side, so that the control handle 116 drives the control rope 115 to move. During the movement of the control rope 115, the locking rod 113 will be pulled to slide in the fixing seat 111, so that the locking rod 113 will be disengaged from the locking slot 107. Only then can the safety door body 101 on one side be opened.

[0036] The specific usage and function of this embodiment: when it is necessary to open the two safety door bodies 101 at the same time, the staff only needs to move the two control handles 116 close to each other. At this time, the two control handles 116 will be adsorbed together due to the attraction of opposite poles of the auxiliary magnets 118. At this time, pulling the control handles 116 can simultaneously release the locks of the two safety door bodies 101.
