Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] combine Figure 1-Figure 7 As shown, the automatic take-up car safety tensioning device mainly includes a handle, a coil spring shaft 17, a take-up reel, a take-up device, a stop pawl assembly, a knob 15, a ribbon 26, etc., wherein:

[0022] The handle includes left and right side plates 2 with the same structure, and the two side plates 2 are connected into one body through several connecting shafts 4 . The rear part of the handle is covered with a casing to facilitate holding and increase hand comfort. The casing is combined with an upper cover 11 and a lower cover 10 and then connected into one body through screws 12 and rivets 13 types of connectors, and the top of the upper cover 11 is also provided with an opening 111, so that Button 8 is exposed outside. In addition, a hook-like hook 3 is connected between the tails of the lef...

Abstract

Provided is a safety tension device of an automatic belt rollback vehicle. A coil spring shaft is installed on the handle of the device. A belt rollback reel with ratchet wheels on both ends is arranged on the coil spring shaft and a belt rollback device realizing the woven belt rollback through coil spring, wherein the two ratchet wheels on the belt rollback reel are connected into one body through a coiling block with an axial opening. One end of the woven belt is connected with the coil spring shaft, and the other end of the woven belt is led out downward through the axial opening of the coiling block and then passes through a limiting device arranged at the front end of the handle; a stop pawl and a spring cooperating with the two ratchet wheels are further arranged on the handle, and a button is installed on the stop pawl, the stop pawl and the two ratchet wheels can be arranged in a disengaged state by pushing the button. The device is simple, convenient and practical, and the traditional initiative pawl cooperating with the ratchet wheel is abandoned. The device is simple in structure, quick and convenient to operate.

Description

technical field [0001] The invention relates to an automobile safety tensioning device, which is used on various automobiles, trailers and motorcycles, can conveniently bind and fix goods, and can also be used as a tool for hand-carrying light goods in daily life. Background technique [0002] Conventional automobile safety tensioning devices are usually composed of a main unit including a handle and a base, long straps and short straps, etc., wherein the main unit adopts the anti-reverse ratchet mechanism principle, that is, the main unit is equipped with active pawls, and the base is equipped with stoppers. The active pawl is directly driven by 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. The stop ratchet prevents the ratchet from reversing, so that a certain tension can be maintained on the strap, and the goods are bundled and fixed. When releasing, pull out the...
