It is responsible for ensuring that the elevator car can move smoothly and accurately along the guide rail during vertical movement, providing passengers with a safe and comfortable riding experience. The car guide shoe is usually composed of a guide shoe head, a guide shoe body, a guide shoe seat and other parts. Among them, the guide shoe head is the part that is in direct contact with the guide rail, and its wear resistance is directly related to the service life of the guide shoe and the smooth operation of the elevator.

[0040] The above scheme is adopted: by placing the first roller 503 and two groups of second rollers 507 on the surface of the guide rail, the first roller 503 and the second roller 507 are in contact with the guide rail, and then the friction coefficient is reduced by the rotation of the first roller 503 and the second roller 507, the energy loss is reduced, and the operation efficiency of the elevator is improved, and the first support spring 504 and the second support spring 508 squeeze the first connecting rod 502 and the second connecting rod 506, so that the first roller 503 and the second roller 507 can be close to the guide rail, preventing children from moving vigorously inside the car and causing the entire car to vibrate, and the restoring force of the first support spring 504 and the second support spring 508 can reduce the wear caused by vibration and impact, making the car more stable during the overall walking process, so as to achieve the user's convenience and no easy shaking when using the device.
