Self-locking carrier

Abstract

This utility model belongs to the field of material handling technology, specifically relating to a self-locking transport vehicle that can automatically clamp stones of different thicknesses. The stone is placed vertically on a supporting mechanism, positioned between the clamping plates of two clamping units. Through the action of a vertical guide mechanism and the weight of the stone itself, the supporting mechanism moves downwards. Under the action of the first, second, and third hinges, the distance between the clamping plates of the two clamping units decreases, causing one clamping plate to contact one side of the stone, and the other clamping plate to contact the other side. This allows for automatic clamping of stones of different thicknesses and effectively improves the stability of stone clamping. It has advantages such as ease of use and high reliability.

Description

Technical Field

[0001] This utility model belongs to the field of material handling technology, specifically relating to a self-locking transport vehicle. Background Technology

[0002] Patent document CN215055475U discloses a stone handling tool, which includes a first fixed arm and a protective spring. A connecting block is provided on the lower outer side of one end of the first fixed arm, and a protective handle is provided on the outer side of the other end of the connecting block. A pivot is provided on the inner wall of the middle end of the first fixed arm. The tool also includes a second fixed arm, which is bolted to a clamping arm to form a detachable structure, allowing for reusability. Users can replace different types of clamping arms as needed to handle stones of various shapes. The clamping arm can slide via a slider on a slide rail on the inner wall of the lower end of the second fixed arm to adjust the length of the clamping end. After adjustment, it is fixed and limited by bolts. A rubber clamp on the outer side of the other end of the clamping arm effectively protects the stone surface from scratches and increases friction to prevent slippage during transport. However, in actual use, different clamping arms need to be replaced according to the size of the stone, which is inconvenient. Furthermore, when the stone is large or heavy, the clamping stability of the clamping arm is low. Utility Model Content
