Description

Technical Field

[0001] This utility model relates to the field of railway EMU maintenance, specifically to a EMU pull-lock door closing device. Background Technology

[0002] When a train malfunctions and the doors need to be opened manually, the onboard mechanic must close the doors individually. If the local door closing is not performed, the train cannot centrally control the door closing, and the safety and reliability of the train doors cannot be guaranteed. Therefore, the onboard mechanic needs to manually close the doors again after getting off the train. However, after getting off the train, the height of the carriage makes it difficult for the mechanic to operate. On the other hand, some mechanics get off the train and close the doors simultaneously in order to perform the local door closing, which poses a safety hazard of being squeezed or falling.

[0003] Therefore, in order to solve the above-mentioned problems, a locking door closing device for high-speed trains is proposed. Utility Model Content

[0004] This utility model addresses the problems mentioned above by designing a pull-lock door closing device for high-speed trains. This device can open quickly, extending its overall length. Operators can press the button on the door from below the train using a lever to close the door. It can also be folded when not in use for easy storage, making it convenient to use and carry.

[0005] To achieve the above objectives, this utility model provides a high-speed train pull-lock door closing device, comprising: a main body, an operating lever, a holding lever, and a spring mechanism. The spring mechanism is provided on one side of each end of the main body, and the operating lever and the holding lever are respectively connected to the two spring mechanisms. The operating lever and the holding lever rotate through the spring mechanism.

[0006] By using the above method, the grip lever and operating lever are opened through the elastic mechanism, extending the overall length and making it convenient to press the buttons at the door position from under the carriage.

[0007] Furthermore, the elastic mechanism includes: a clamping plate, a rotating shaft, and a torsion spring. The clamping plate is fixedly connected to the top and bottom of the main body. The rotating shaft is mounted on the clamping plate. The operating rod and the gripping rod are rotatably connected to the rotating shaft, and the side near the main body is an open structure. A torsion spring is provided on the rotating shaft, and the two ends of the torsion spring abut against the side wall of the main body and the inner wall of the operating rod and the gripping rod, respectively.

[0008] Furthermore, the elastic mechanism also includes a positioning pin and a positioning hole. The positioning hole is provided on the clamping plate, and the operating rod and the gripping rod are provided with holes corresponding to the positioning hole. The positioning pin is placed in the positioning hole to fix the gripping rod and the operating rod.

[0009] In this way, when the two rods are retracted, pressure is applied to the torsion spring, which is then secured by the locating pin. When needed, the locating pin is pulled out, and the two rods extend under the elastic force of the torsion spring. They are then re-secured by inserting the locating pin again, and the rods are ready for use.

[0010] Furthermore, it also includes an auxiliary device, which is disposed at the bottom of the main body.

[0011] Furthermore, the auxiliary device includes: a limiting frame, a positioning plate, a positioning notch, a positioning shaft, a connecting block, and a pull rod. The limiting frame is suspended from the top of the inner wall of the main body. A sliding groove is provided at the bottom of the main body. The positioning plate is fixedly connected to the bottom of the inner wall of the main body and located on both sides of the sliding groove. A plurality of positioning notches are evenly provided on the positioning plate. The positioning shaft is placed in the positioning notch. The upper end of the connecting block is connected to the positioning shaft, and the lower end passes through the sliding groove and is fixedly connected to the pull rod.

[0012] With the increased length of the device body and the greater distance between the mechanic and the operating button on the ground, making it difficult to press accurately and forcefully, a pull rod is added to the middle of the device to improve its operability. The pull rod lifts the device, providing auxiliary stability. When pressing is required, gripping the pull rod and applying downward force allows the pressing head to effectively press down on the button.

[0013] Furthermore, the auxiliary device also includes a baffle, which is fixedly connected to the end of the positioning plate and connected to the bottom of the limiting frame.

[0014] Furthermore, the auxiliary device also includes a positioning buckle, which is fixedly connected to the bottom of the main body, and the pull rod is engaged with the positioning buckle.

[0015] Furthermore, a handle is fixedly connected to the top of the main body.

[0016] Furthermore, the operating lever includes an extension column and a pressing head, with one end of the extension column connected to the end of the operating lever and the pressing head connected to the other end of the extension column.

[0017] In summary, this utility model has the following advantages and beneficial technical effects: 1. The present invention relates to a high-speed train pull-lock door closing device that can be opened quickly, extending the overall length, allowing the operator to press the button at the door from below the train by holding a lever, thereby closing the door; 2. The pull-lock door closing device of this utility model can be folded for easy carrying and storage when not in use; 3. The bottom of the pull-lock door closing device of this utility model is equipped with an auxiliary device, which makes the operation more convenient and improves the user experience of the mechanic.
