Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an oil-free sliding guide shoe which is easy to disassemble and assemble. Background Art

[0002] The guide shoe is a sliding component installed between the elevator guide rail and the car. It can connect the car to the guide rail so that the car can only move up and down. At present, the shoe lining of the existing guide shoe is usually wrapped with rubber for shock absorption and pressure resistance, so that the impact of the collision between the guide shoe and the elevator guide rail on the operation of the car is minimized, providing a guarantee for the smooth operation of the elevator.

[0003] The existing patent publication number is CN210176261U, which discloses a sliding guide shoe that is easy to install and disassemble, including a die-cast base, a rubber shock-absorbing pad is provided on the outer surface of the lower end of the die-cast base, a shock-absorbing sleeve is provided on the inner surface of the middle part of the upper end of the die-cast base, and a shoe lining is provided on the outer surface of the middle part of the shock-absorbing sleeve. The utility model uses a die-cast base, and people can directly pinch the shock-absorbing sleeve or the shoe lining to disassemble and install it using a snap-in method, and can achieve the disassembly and assembly of the shock-absorbing sleeve and the shoe lining with one hand, which is convenient for people to operate. Through the shock-absorbing sleeve and the shoe lining, they can be directly installed by snapping in, which is convenient for people to install and replace. The wear condition can also be judged by observing the color difference between the shock-absorbing sleeve and the shoe lining. Through the rubber shock-absorbing pad, it can be used in conjunction with the shock-absorbing sleeve to improve the product's buffering and shock absorption capabilities, enhance the stability of the elevator operation, and facilitate people's use.
