[0003] The existing electromechanical equipment is the core component of elevator operation, including the motor, controller, speed governor, safety brake, guide rails, car, and door system. These devices work together to ensure the safe and stable operation of the elevator. The motor is the power source of the elevator, driving the traction sheave to move the car up and down. The controller is responsible for controlling the elevator's speed, direction, and stopping floors. The speed governor and safety brake are important safety devices of the elevator. When the elevator overspeeds, the speed governor will trigger the safety brake, braking the car onto the guide rails to prevent the elevator from falling.

[0004] However, existing electromechanical equipment lacks protective devices during use, making it susceptible to impacts and damage from external objects, which may even lead to personnel injury. Furthermore, it exposes the equipment to the external environment, making it more vulnerable to corrosion from dust, moisture, and corrosive substances, thus affecting its performance and lifespan. Therefore, an electrical safety protection device is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an electrical safety protection device, comprising a base 1, a fixing plate 10 fixedly connected to the outer wall of the base 1, a fixing groove 11 formed inside the fixing plate 10, a fixing cover 2 fixedly connected to the upper surface of the base 1, a rotating cover 3 rotatably connected to the outer wall of the fixing cover 2, a locking post 9 slidably connected to the outer wall of the rotating cover 3, the locking post 9 slidably connected to the inner wall of the fixing groove 11, a locking block 8 fixedly connected to the outer wall of the locking post 9, a sliding column 5 slidably connected to the outer wall of the rotating cover 3, a limiting plate 7 fixedly connected to one end of the sliding column 5, a spring 6 sleeved on the outer wall of the sliding column 5, one end of the spring 6 fixedly connected to the outer wall of the limiting plate 7, the other end of the spring 6 fixedly connected to the outer wall of the rotating cover 3, and a switch assembly provided on the outer wall of the rotating cover 3, the switch assembly being used to rotate the rotating cover 3.

[0033] Specifically, pull the locking pin 9 to slide it out of the fixing groove 11. At the same time, the locking pin 9 drives the locking block 8 to rise and fall. Then, the locking block 8 pushes the limiting plate 7 to move. The limiting plate 7 then drives the sliding pin 5 to move and compresses the spring 6. When the locking block 8 moves to the top of the limiting plate 7, the spring 6 rebounds and drives the limiting plate 7 back to its original position, fixing the locking block 8. Then, the rotating cover 3 is opened to maintain the internal mechanism. After maintenance, the rotating cover 3 is closed, and the sliding pin 5 is pulled. The sliding pin 5 drives the limiting plate 7 to move. Gravity causes the locking pin 9 to fall back into the fixing groove 11 for fixation. In this way, the rotating cover 3 and the fixing 2 can protect the interior, effectively preventing dust, moisture and other pollutants from entering the equipment, reducing the possibility of equipment failure, reducing the impact of the external environment on the equipment, and extending the service life of the equipment. At the same time, it can be easily opened and closed, making it convenient for maintenance personnel to perform equipment maintenance and repair work.

[0034] Reference Figure 1 The switch assembly includes a handle 4, the outer wall of which is fixedly connected to the outer wall of the rotating cover 3.

[0035] Specifically, the handle 4 can drive the rotating cover 3 to rotate, allowing the user to easily grip and apply force, thereby driving the rotating cover 3 to rotate.

[0036] Reference Figure 1 , Figure 3 and Figure 4The rotating cover 3 has a wiring port 12 inside and a slot 13 inside. The base 1 has a fixed disc 25 fixedly connected to its outer wall. The fixed disc 25 has a limiting groove 22 inside. The fixed disc 25 has a turntable 14 rotatably connected to its outer wall. The turntable 14 has a connecting plate 20 fixedly connected to its inner wall. The connecting plate 20 has a slide rail 23 inside. The turntable 14 has an adjusting plate 21 inside. The adjusting plate 21 has a connecting column 24 fixedly connected to its outer wall. The connecting column 24 is slidably connected to the slide rail 23 inside. The connecting column 24 is slidably connected to the limiting groove 22 inside. The turntable 14 has a connecting shell 19 fixedly connected to its outer wall. The connecting shell 19 has a lifting column 15 slidably connected to its inner wall. The lifting column 15 has a fixed disc 18 fixedly connected to its outer wall. The lifting column 15 has a spring 17 sleeved on its outer wall. The upper surface of the spring 17 is fixedly connected to the connecting shell 19. The lower surface of the spring 17 has a retaining ball 16 fixedly connected to its lower surface. The retaining ball 16 is slidably connected to the slot 13 inside.

[0037] Specifically, rotating the turntable 14 causes the fixed connecting plate 20 to rotate. The connecting plate 20 then rotates the internally opened slide rail 23, which in turn moves the internal connecting column 24. The connecting column 24 then moves the bottom adjusting plate 21, causing the connecting column 24 at the bottom of the adjusting plate 21 to slide within the limiting groove 22, thereby closing the wiring port 12. Simultaneously, rotating the turntable 14 causes the connecting housing 19 to rotate, resulting in the outer wall of the base 1 exerting a pushing force on the retaining ball 16, which in turn raises the lifting column 15 and compresses the second spring 17. Once the desired position is reached, the second spring 17 rebounds, causing the retaining ball 16 to be engaged in the retaining groove 13. Internally, the turntable 14 is fixed to prevent it from rotating on its own. Closing unused wiring ports 12 can prevent accidental contact by personnel or entry of foreign objects, reduce the risk of electric shock and short circuit, prevent dust, moisture and other contaminants from entering unused wiring ports 12, reduce the possibility of equipment failure, reduce the impact of the external environment on unused wiring ports 12, extend the overall service life of the equipment, facilitate the identification and management of used and unused wiring ports 12, and facilitate maintenance personnel to carry out maintenance and repair work.

[0038] Working principle: Pulling the locking pin 9 causes it to slide out of the fixing groove 11. Simultaneously, the locking pin 9 drives the locking block 8 to rise and fall. The locking block 8 then pushes the limiting plate 7 to move. The limiting plate 7 then drives the sliding pin 5 to move, compressing the spring 6. When the locking block 8 reaches the top of the limiting plate 7, the spring 6 rebounds, causing the limiting plate 7 to return to its original position and fix the locking block 8. The rotating cover 3 can then be opened via the handle 4 for internal maintenance. After maintenance, the handle 4 is closed, and pulling the sliding pin 5 moves the limiting plate 7. Gravity causes the locking pin 9 to fall back into the fixing groove 11 for fixation. The rotating cover 3 and the fixing cover 2 protect the internal structure. When the wiring port 12 is not... In use, rotating the turntable 14 causes the fixed connecting plate 20 to rotate, which in turn causes the internal slide rail 23 to rotate. The slide rail 23 then causes the internal connecting column 24 to move, which in turn causes the bottom adjusting plate 21 to move. At the same time, the connecting column 24 at the bottom of the adjusting plate 21 slides inside the limiting groove 22, thereby closing the wiring port 12. Simultaneously, rotating the turntable 14 causes the connecting housing 19 to rotate, which causes the outer wall of the base 1 to push the locking ball 16, thereby causing the lifting column 15 to rise and compress the second spring 17. After reaching the appropriate position, the second spring 17 rebounds, causing the locking ball 16 to be locked inside the locking groove 13, thereby closing the wiring port 12.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
