Description

Technical Field

[0001] The utility model belongs to the field of elevator door accessory devices, and in particular relates to a wear-resistant elevator door anti-slip groove device. Background Art

[0002] The elevator door anti-slot device is a safety device used to prevent the elevator door from falling off the track or out of the slot during operation.

[0003] When the existing elevator door anti-slip groove device is in use, since the usual elevator sill is a guide groove with a concave cross-section on the upper surface of the sill, this sill is easily deformed due to the impact of the elevator door during use, and the door slider is easily disengaged from the guide groove when being lifted upward, thereby affecting the limiting and guiding effect of the sill on the elevator door, and the friction between the single limiting groove and the door slider is relatively large, so the service life of the limiting groove and the door slider is affected.

[0004] Therefore, in view of the problems that when the above-mentioned elevator door anti-slip groove device is in use, the friction between its single limiting structure and the sliding block structure is relatively large, which greatly affects its service life, and the limiting structure is easily deformed when impacted, and the effect of limiting and guiding the elevator door is not good, a wear-resistant elevator door anti-slip groove device is developed. By adding an external limiting structure, an internal limiting mechanism and a central limiting structure to the elevator door anti-slip groove device, the effect of the device in limiting and guiding the elevator door can be greatly improved, and the service life of the device can be improved.

[0012] Preferably, the second limiting assembly includes a second limiting block and a hollow groove. The second limiting block is fixedly connected to the center of the lower end of the supporting block. The second limiting block is in an inverted trapezoidal shape. The front and rear ends of the second limiting block are penetrated by a hollow groove. The second limiting block is adapted to the second limiting groove.
