Problems solved by technology

[0005] The object of the present invention is to provide a safety belt retractor, which solves the problem that when the existing safety belt retractor is in use, it is necessary to press one end of the buckle for a long time and overcome the elastic force of the torsion spring itself to make the buckle Only when the other end of the piece is tilted up can the seat belt be moved out of the retractor. Pressing the buckle for a long time will cause discomfort such as sore hands

[0028] see Figure 1 to Figure 3 ,in figure 1 It is a schematic diagram of the overall structure of the seat belt retractor according to the first embodiment of the present invention, figure 2 It is a schematic diagram of the connection between the winding roller and the tightening spring according to the first embodiment of the present invention, image 3 It is a schematic diagram of the connection between the bevel teeth and the fixing plate according to the first embodiment of the present invention. The present invention provides a seat belt retractor, which includes a casing 100, a winding roller 101, a winding assembly, a safety belt 102 and a fixing assembly. The winding assembly includes a box body 108, a tightening spring 109 and a box cover 110, and the fixing assembly includes a clamping shell 103, a rotating shaft 104, a fixing plate 105, a bevel tooth 106 and a pulling plate 107;

Embodiment approach

[0029] For this specific embodiment, the rewinding roller 101 is used to rewind the safety belt 102 inside the casing 100 , one end of the safety belt 102 is fixedly connected to the rewinding roller 101 , and the other end extends Out of the casing 100, the safety belt 102 is made of nylon material, the take-up roller 101 is rotatably installed inside the casing 100, the left end of the safety belt 102 is fixed with the take-up roll 101, the safety The right end of the belt 102 is located on the outer side of the outer shell 100, and the right end of the safety belt 102 is provided with a latch, which is convenient for connecting the human body to the seat and protecting the human body.

[0030] The clip shell 103 is slidably connected to the safety belt 102 and is located outside the safety belt 102 , and the rotating shaft 104 is fixedly connected to the clip shell 103 and is located at the position of the clip shell 103 close to the safety belt 102 . On one side, the fixin...

Abstract

The invention relates to the technical field of safety belts, in particular to a safety belt retractor and a safety belt assembly.The safety belt retractor comprises a shell, a winding roller, a winding assembly, a safety belt and a fixing assembly, the fixing assembly comprises a clamping shell, a rotating shaft, a fixing plate and conical teeth, and a human body on a seat is limited and protected by pulling the safety belt; after the safety belt is continuously pulled to move out by a certain distance, the clamping shell slides, the left end of the clamping shell makes contact with the right end of the shell, then the fixing plate is pushed to move, the conical teeth are made to be close to the safety belt, and finally the conical teeth are inserted into the safety belt, so that the clamping shell is fixed to the outer side of the safety belt, and the safety belt is loosened; at the moment, due to the fact that the tightening spring deforms to drive the winding roller to wind the safety belt, the clamping shell abuts against the outer shell, the mode that the safety belt is limited through a contracting fastener is replaced, the safety belt can be moved out without continuously pressing a locking fastener, force applied to the hand is reduced, and discomfort such as aching pain of the hand is avoided.

Description

technical field [0001] The invention relates to the technical field of seat belts, in particular to a seat belt retractor and a seat belt assembly. Background technique [0002] The retractor is the core component of the car seat belt. It is widely used in automobiles, airplanes and amusement facilities. It can connect people with the seat and avoid injury when people leave the seat in the event of an accident. The traditional seat belt retractor is used in the process. It is necessary to forcefully pull the seat belt out of the retractor, and after the seat belt is pulled out, it will be subject to the retracting force of the retractor, and part of the force acting on the human body will tighten the body. discomfort. [0003] An existing seat belt retractor presses one end of the locking member, and the other end of the locking member is lifted by a torsion spring, so that the locking member is separated from the slot on the seat belt, so that the installation belt can be ...
