Correcting device with decoration slots

Abstract

The invention provides a correcting device with decoration slots. The correcting device is installed at the bottom of a trackless retractable door. The correcting device with the decoration slots comprises a first guide track section and a second guide track section which are mutually embedded and guide wheel groups of a track mechanism connected between the first guide track section and the second guide track section in a sliding mode. Each guide wheel group is of a recessed rotating body structure, the guide wheel groups are arranged in the first guide track section in pair, and the first guide track section and the second guide track section further comprise the slots for inserting decoration pieces. The correcting device achieves mechanical correcting of the trackless retractable door in the moving direction by means of retractable movement of the first guide track section and the second guide track section. The decoration pieces can be conveniently installed on the correcting device, and a beautifying effect is achieved.

Description

technical field [0001] The invention relates to a trackless automatic telescopic door, in particular to a guiding device capable of maintaining a straight line movement of the trackless telescopic door during the unfolding or contracting process. Background technique [0002] Automatic telescopic doors are generally divided into two types: tracked and trackless. Among them, railed telescopic doors need to lay tracks on the ground to achieve linear motion, which increases the trouble of installation and brings inconvenience to passing vehicles and pedestrians. Although the existing trackless telescopic door does not need to lay two special tracks, it also needs to lay a guide rail on the ground, and set rollers at the bottom of the telescopic door. The rollers slide along the two sides of the guide rail, and the telescopic door realizes linear movement through the guide rail and the guide wheel. , but it is not off track in essence, nor is it truly trackless. Therefore, a ki...

AI Technical Summary

Problems solved by technology

Although this solution solves the problem of straight-line alignment, the misalignment of the alignment rod in the alignment groove is easy to swing, and the structure is not stable. However, if the fit is too tight, the friction force will be too large, which will affect the normal movement of the automatic telescopic door. Therefore, It is still necessary to propose a guiding structure for trackless automatic retractable doors
