Description

Technical Field

[0001] The utility model relates to the field of elevator operation panels, in particular to a quick replacement structure for elevator operation panels. Background Art

[0002] An elevator operation panel, also known as a "control box" or "control panel", is an important component used to control the operation of an elevator in an elevator system. It is usually installed inside the elevator car or in the waiting hall for passengers or operators to use, so as to realize functions such as floor selection, door opening and closing, and emergency call of the elevator.

[0003] With the continuous development of elevator technology, quick disassembly and installation have become an important trend in modern elevator design. An operation panel that cannot be quickly disassembled may mean that the elevator design lags behind the development of industry technology to a certain extent. The inability to quickly disassemble the operation panel may also limit the flexibility of elevator use in different scenarios. For example, in some places where the elevator configuration needs to be frequently changed (such as exhibitions, temporary buildings, etc.), an operation panel that cannot be quickly disassembled will increase the difficulty and cost of changing the configuration. In order to improve the safety, reliability and use efficiency of elevators, it is recommended that elevator manufacturers and designers fully consider the quick disassembly of operation panels in future product designs.

[0023] Please refer to Figures 1 to 4, in this embodiment, a quick replacement structure for an elevator operation panel is provided, including an elevator operation panel 2 and a car body 1. Limiting card slots 4 are opened on both the left and right sides of the elevator operation panel 2, and fixing slots 5 corresponding to and engaging with the elevator operation panel 2 are opened on the car body 1. An encapsulation slot 6 is opened on the car body 1, and the encapsulation slot 6 is spaced and opened below the fixing slot 5. The bottom wall of the encapsulation slot 6 is rotatably installed with a cover 3 through a hinge. A rotary lock is installed on the cover 3, and the cover 3 is locked and cooperated with the car body 1 through the rotary lock, so that the cover 3 can encapsulate the encapsulation slot 6 to protect the limiting mechanism 8 from being affected by external factors and provide a limiting ability for the elevator operation panel 2. In the middle of the top wall of the encapsulation slot 6, a limiting slot 7 is opened. The limiting slot 7 is opened below the fixing slot 5, and the fixing slot 5 and the limiting slot 7 are spaced and opened on the car body 1. A limiting mechanism 8 is arranged in the limiting slot 7. A plurality of cylindrical long slots 9 are opened on the left and right side walls of the limiting slot 7. Limiting sliding slots 11 are opened on the left and right side walls of the fixing slot 5. The two limiting sliding slots 11 are symmetrically arranged left and right. A U-shaped slot 10 is opened between the long slots 9 on the left and right sides of the limiting slot 7 and the fixing slot 5 on the same side as the long slots 9. The diameter of the U-shaped slot 10 is larger than the diameter of the long slots 9. A plurality of accommodating slots 12 are opened at the bottom of each of the two limiting sliding slots 11. A return spring 13 is arranged in each accommodating slot 12, and the return spring 13 is fixed at the bottom of the accommodating slot 12;

[0024] The limiting mechanism 8 includes a threaded rod 81, a rotary knob 82, a triangular top sleeve 83, a limiting slide rod 84, a ball 85 and a limiting strip 86. The threaded rod 81 is rotatably arranged between the middle of the lower groove wall of the encapsulation groove 6 and the middle of the top groove bottom of the limiting groove 7. The bottom of the threaded rod 81 is fixedly installed with the rotary knob 82, and the rotary knob 82 is arranged in the encapsulation groove 6, so that the rotary knob 82 can be manually rotated by a person in the encapsulation groove 6 by opening the cover 3. A number of triangular top sleeves 83 are equidistantly sleeved on the threaded rod 81, and the triangular top sleeves 83 slide directionally in the limiting groove 7. The triangular top sleeves 83 will be engaged with the threaded rod 81, so that the triangular top sleeves 83 can lift the height in the limiting groove 7. A slidable limiting slide rod 84 is arranged in the long groove 9. One end of the limiting slide rod 84 is fixedly installed with a limiting block, and the limiting block is arranged in the U-shaped groove 10. By sliding the limiting block in the U-shaped groove 10 and limiting the sliding distance to the connection between the U-shaped groove 10 and the long groove 9, the whole limiting slide rod 84 is prevented from disengaging from the cavity of the long groove 9. Two limiting slide rods 84 at the same horizontal height on the left and right sides of the limiting groove 7 are set as a group, and the two limiting slide rods 84 in each group are in contact with the side inclined surfaces of the triangular top sleeve 83. When the triangular top sleeve 83 lifts the height in the limiting groove 7, the limiting slide rod 84 can be pushed from the long groove 9 into the U-shaped groove 10 by the inclined surfaces on both sides of the triangular top sleeve 83. A number of balls 85 are placed in the U-shaped groove 10. Two slidable limiting strips 86 are arranged in the two limiting chutes 11. The two limiting strips 86 are symmetrically arranged left and right, and the two limiting strips 86 are respectively subjected to the pulling force brought by the elastic deformation of the return springs 13 in a plurality of accommodating grooves 12 communicated with the limiting chutes 11 where they are located. The limiting strips 86 are correspondingly engaged with the limiting card slots 4.

[0025] The working principle of the present utility model is:

[0026] When the utility model is in use, maintenance personnel use a key to unlock the turn lock on the cover 3, so that the turning knob 82 in the encapsulation groove 6 is presented within the view of the maintenance personnel. The maintenance personnel manually rotate the turning knob 82, and the turning knob 82 drives the threaded rod 81 to rotate. The triangular top sleeve 83 meshes with the threaded rod 81, so that the triangular top sleeve 83 slides downward in the limiting groove 7 in a fixed direction, releasing the pressure on the limiting slide rod 84. At this time, the return spring 13 will contract, pulling the limiting strip 86 to press the ball 85 in the U-shaped groove 10, so that the ball 85 rolls in the U-shaped groove 10, transmitting the pressure to the limiting slide rod 84, so that the limiting slide rod 84 slides in the long groove 9 following the sliding distance of the triangular top sleeve 83 in the limiting groove 7. Furthermore, the limiting strip 86 will release the engagement with the limiting card slot 4, and the elevator operation panel 2 on the car body 1 is removed. After replacing the new elevator operation panel 2, the turning knob 82 is reversed, so that the threaded rod 81 and the triangular top sleeve 83 are reversely meshed, and the triangular top sleeve 83 slides upward in the limiting groove 7 in a fixed direction, thus pressing the limiting slide rod 84 to slide in the long groove 9, so that the ball 85 rolls in the U-shaped groove 10. Furthermore, the ball 85 presses and pushes the limiting strip 86 to slide toward the new elevator operation panel 2 in the limiting sliding groove 11, and the limiting strip 86 is correspondingly engaged with the limiting card slot 4, completing the quick replacement task of the elevator operation panel 2, reducing the cumbersome disassembly and assembly procedures of twisting screws for the traditional operation panel, and enabling the elevator operation panel 2 to be modularly assembled, simplifying the connection between the elevator operation panel 2 and the car body 1, and accelerating the maintenance work of the elevator operation panel 2.

[0027] The above is only the preferred specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the present utility model, making non-substantive changes to the present utility model using this concept, shall fall within the scope of infringement of the protection scope of the present utility model.
