Description

Technical Field

[0001] The utility model belongs to the technical field related to elevator hall doors, and in particular relates to a safety protection structure for elevator hall doors. Background Art

[0002] Elevator hall doors refer to the doors at the entrance and exit of the elevator. They isolate the elevator car from the space outside the elevator, ensuring the safety and normal operation of the elevator during operation. Elevator hall doors are usually automatic doors. When opening the door, they can sense the presence of people through sensors and open automatically. When people enter or leave the elevator, the elevator door will automatically open and close to improve the convenience and safety of the elevator.

[0003] However, when the existing elevator hall door is opening and closing, the sliding door cannot detect in time that a person or object is trapped, which increases the risk of being trapped. The user may be accidentally trapped by the sliding door, causing physical injury. Utility Model Content

[0004] The purpose of the utility model is to provide a safety protection structure for elevator hall doors, so as to solve the problem in the above-mentioned background technology that in the process of opening and closing the existing elevator hall doors, the sliding doors cannot detect in time that people or objects are clamped, which increases the risk of clamping injuries. Users may be accidentally clamped by the sliding doors, causing physical injuries.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator hall door safety protection structure, comprising a control chamber;

[0006] A synchronous belt is arranged inside the control cavity, synchronous wheels are arranged on the left and right sides of the synchronous belt, a guide pulley is arranged outside the synchronous belt, a motor is arranged on the right side of the synchronous belt, and an elevator hall door is arranged below the control cavity, and the elevator hall door is powered by a power cord;

[0007] A sliding door is arranged at the inner side of the elevator hall door, an anti-pinch mechanism is arranged at the inner side of the sliding door, and a fixing rod is arranged at the right side of the anti-pinch mechanism.

[0008] Preferably, fixed blocks are respectively provided on the upper and lower sides of the fixed rod, the fixed blocks are fixedly connected to the sliding door, a limit block is provided in the internal array of the fixed rod, a sleeve is provided at the position above the limit block, a buffer spring is provided at the position above the sleeve, the sleeve is slidably connected to the fixed rod, and a bracket is provided at the outer side of the sleeve.

[0009] Preferably, an anti-pinch rod is provided at an inner position of the fixing rod, rollers are provided in an array at an inner position of the anti-pinch rod, and the anti-pinch rod and the sleeve are rotatably connected to the bracket.

[0010] Preferably, a pressure sensor is provided at the top of the buffer spring, and the pressure sensor is fixedly connected to the fixing block.

[0011] Preferably, a door frame mechanism is provided at the bottom of the elevator hall door, a slide groove is opened at an internal position of the door frame mechanism, a support frame is provided in an array inside the door frame mechanism, a right-angle frame is provided at an outer position of the support frame, and the support frame and the right-angle frame are fixedly connected to the sliding door.

[0012] Preferably, a sliding block is provided at the bottom of the support frame, and connecting blocks are respectively provided on the left and right sides of the sliding block, the connecting blocks are nested and connected to the support frame, and the sliding block is slidably connected to the slide groove.

[0013] Preferably, the door frame mechanism, support frame and right-angle frame are made of steel material, and the sliding door moves via guide rails and pulleys.

[0014] Compared with the prior art, the utility model provides an elevator hall door safety protection structure, which has the following beneficial effects:

[0015] 1. Through the arrangement of the fixing rod, the fixing block, the limit block, the sleeve, the buffer spring, the bracket, the anti-pinch rod, the roller and the pressure sensor, when the sliding door encounters an object or a human body during its movement, the anti-pinch rod inside the sliding door can quickly sense it and realize elastic deformation through contact with the object, and then push the sleeve upward through the bracket to fully release the buffer spring. During the release process, the elasticity generated by the anti-pinch rod can be transmitted to the top pressure sensor through the mechanical transmission path. In this way, when the sliding door encounters an obstacle, the pressure sensor can immediately sense it and send a signal to the upper control chamber to urge the sliding door to reopen, so as to achieve the purpose of safety anti-pinch and protect the pedestrians. The safety of people or objects is improved, and accidental injuries caused by obstructions during the movement of the sliding door are reduced. When clothes are caught and the pressure sensor cannot be touched, the user can directly pull the caught clothes. The internal roller will rotate due to the user's pull, driving the clothes to be released quickly, thereby avoiding the trouble of clothes being stuck and unable to be released. Users do not need to wait for the elevator door to open again, but can directly solve the problem by pulling the clothes, saving time. This not only facilitates the user's operation, but also improves the efficiency and user experience of the elevator. At the same time, this design can also reduce the inconvenience or accidents caused by the clothes being clamped, and improve the safety and convenience of the elevator.

[0016] 2. Through the door frame mechanism, slide slot, support frame, right-angle frame and slider, the internal slider mainly plays the role of reducing the load of the top motor and protecting the motor. When the top motor drives the sliding door to move, the slider will slide in the slide slot, which reduces the motor load and wear. In addition, the internal slider can also protect the stability of the elevator door mechanical structure and reduce the noise and vibration of the motor, thereby achieving a more stable and smooth elevator experience. The fixed connection between the support frame and the right-angle frame and the sliding door can effectively prevent the sliding door from shaking and deflecting during the sliding process. The angle design of the right-angle frame enables it to provide additional support and stability to prevent the sliding door from being deformed or shaken by external forces.

[0031] In this embodiment, the specific implementation steps of the elevator hall door safety protection structure are as follows: first, the motor in the top control chamber 1 drives the synchronous wheel 3 and the synchronous belt 2 to rotate, and then the guide pulley 4 on the synchronous belt 2 drives the bottom sliding door 7 to move. When there is an object or a human body in the middle of the sliding door 7, the anti-pinch rod 13 inside the sliding door first touches the object, and then the anti-pinch rod 13 moves backward, and the bracket pushes the sleeve 19 upward in the fixed rod 11, and then the sleeve 19 pushes the buffer spring 15 upward, and the top pressure sensor 17 sends a signal to the upper control chamber 1 after reaching the critical value, and the sliding door 7 is reopened to prevent further injuries.

[0032] like Figure 1 and Figure 2As shown, fixed blocks 16 are respectively provided on the upper and lower sides of the fixed rod 11, and the fixed block 16 is fixedly connected to the sliding door 7. A limit block 20 is arranged in an array inside the fixed rod 11, a sleeve 19 is arranged at a position above the limit block 20, and a buffer spring 15 is arranged at a position above the sleeve 19.
