Description

Technical Field

[0001] This utility model relates to the field of elevator control box technology, and in particular to an elevator control box. Background Technology

[0002] The elevator control box is a key component of an elevator system, primarily responsible for controlling the elevator's operation. It receives and processes various signals to control the elevator's start, run, and stop. When a passenger presses a floor button or internal call button, the control box responds quickly and determines the elevator's direction of travel and stopping floor based on a preset algorithm.

[0003] When installing existing elevator control boxes, the cables on the buttons need to be connected to the control panel. Due to the vibration generated by the elevator during long-term use, the wiring terminals may become loose, the plugs may have poor contact, or the cables may wear and short-circuit or break, which may lead to signal transmission interruption or errors. Therefore, a limit mechanism needs to be designed to fix the cables when they are connected. Utility Model Content

[0025] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an elevator control box includes a panel 1 and a control box 2. The control box 2 is installed on the rear side of the panel 1. A control panel 19 is installed on the front side of the panel 1 near the top. Two buttons 3 are installed on the front side of the panel 1. The two buttons 3 and the control panel 19 extend to the inner cavity of the control box 2. Cables 4 are plugged into the rear side of the two buttons 3. Two limiting mechanisms are provided on the rear side of the panel 1. The two limiting mechanisms are arranged symmetrically at the top and bottom.

[0026] The limiting mechanism includes a mounting plate 5, which is fixedly connected to the rear side of the panel 1 at its front. A sleeve plate 7 is fixedly connected to the bottom of the mounting plate 5 near the rear side. The inner cavity of the sleeve plate 7 has a threaded groove, which engages with a lead screw 12. A knob 6 is fixedly connected to the rear end of the lead screw 12. An insulating sleeve is provided on the outside of the knob 6. The mounting plate 5 is made of magnetic material. A limiting plate 8 is fixedly connected to the bottom of the limiting plate 8 near the rear side. A lifting plate 9 is slidably connected to the limiting plate 8. The lead screw 12 is located behind the lifting plate 9. Two hinge plates 18 are fixedly connected to the rear side of the lifting plate 9. The two hinge plates 18 are arranged symmetrically on the left and right sides. The hinge plate 18 on the left side is hinged to a second concave plate 14, and the hinge plate 18 on the right side is hinged to a first concave plate 13. The first concave plate 13 has a slot. The first concave plate 13 and the second concave plate 14 are connected to each other. Pressing blocks 15 are hinged to opposite sides of the two concave plates 14. Pressing balls are fixedly connected to the corresponding sides of the first concave plate 13 and the second concave plate 14. A pressure plate 10 is fixedly connected to the bottom of the mounting plate 5 near the rear side. A bearing plate 11 is fixedly connected to the bottom of the mounting plate 5 near the rear side. Several V-shaped grooves are opened on the bearing plate 11, and the several V-shaped grooves are arranged linearly from left to right. Several through holes are opened on the pressure plate 10, and the several through holes are arranged linearly from left to right. A lifting rod 17 is passed through the through holes. A spring 16 is sleeved on the outside of the lifting rod 17. The front end of the spring 16 is fixedly connected to the lifting rod 17, and the rear end of the spring 16 is fixedly connected to the pressure plate 10. A rectangular opening is opened at the bottom of the mounting plate 5 near the rear side. Several cables 4 pass through the adjacent V-shaped grooves and extend to the rectangular opening.

[0027] Working principle: First, the operator attaches the mounting plate 5 to the panel 1 and starts the knob 6 to rotate the lead screw 12. When the lead screw 12 rotates, it moves backward and presses the lifting plate 9 to move backward. When the lifting plate 9 moves backward, the movement trajectory can be limited by the limiting plate 8. When the lifting plate 9 moves, it can drive the first concave plate 13 and the second concave plate 14 to move backward synchronously. Since the first concave plate 13 and the second concave plate 14 are hinged with the pressing block 15, the impact force generated by the lifting rod 17 and the cable 4 can be reduced, and the outer surface of the cable 4 can be protected. When the cable 4 is fixed, it can prevent the vibration generated by the elevator operation from causing the cable 4 and the terminal to loosen, which would lead to signal transmission interruption or error.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
