Anti-loosening hook for tensioning device and automobile safety tensioning device with anti-loosening hook

Abstract

The utility model relates to an anti-loose hook for a tensioning device and an automobile safety tensioning device with the anti-loose hook, the anti-loose hook comprises a hook body and a hook arranged on the hook body, and the anti-loose hook is characterized in that a shock absorption elastic body is arranged between the hook body and the hook or on the hook body and on the side opposite to the hook. The tensioning device comprises a main machine and is characterized in that a hook is installed on the main machine, and a hook body of the hook is connected to the main machine through a binding belt, or the hook body of the hook is directly connected to the main machine. The anti-loosening hook for the tensioning device has the advantages that the damping elastic body is arranged between the hook body and the hook or on the side, opposite to the hook, of the hook body, the damping, buffering and anti-loosening effects can be achieved, the anti-loosening hook is installed on a main machine of the automobile safety tensioning device, and when jolt and vibration happen, the impact force can be effectively absorbed, so that the safety risk caused by hook breakage or binding belt looseness is reduced.

Description

technical field

[0001] The invention relates to a tensioning device for fixing and fastening goods on automobiles, trailers, airplanes, ships and other means of transportation, in particular to an anti-loosening hook for the tensioning device and an automobile safety hook with the hook. Tension device. Background technique

[0002] The car safety tensioning device is generally composed of the tensioning device host, long straps, short straps, etc. Among them, the host part usually adopts the principle of anti-rotation ratchet mechanism, directly drives the active pawl with the handle, the active pawl pushes the ratchet, and the ratchet directly drives the main shaft, thereby tightening the strap wrapped around the main shaft, and the stop ratchet The pawl prevents the ratchet from reversing, so that a certain tension can be maintained on the strap, and the goods are bundled and fixed.
