Detailed description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.
Referring to FIGS. 1 to 3 , in the embodiment of the present invention, the noise-suppressing automobile seat belt retractor includes a mounting seat 1 , a plurality of mounting holes 11 are provided on the mounting seat 1 , and a retractor is installed at the front end of the mounting seat 1 2. A side cover 21 is installed on the left end wall of the winder 2, a cover 3 is installed on the left end of the side cover 21, the right end of the winder 2 is pressed against the left and right casings 4, and an outlet frame 5 is installed at the front of the top of the winder 2. A cavity 51 is provided, the left and right end walls of the cavity 51 are provided with a plurality of movable cavities 52, the connecting plates 53 are installed in the plurality of movable cavities 52, and the springs 54 are installed on the outer end walls of the plurality of connecting plates 53, and Slide rollers 55 are installed on the inner sides of the plurality of connecting plates 53 , and a safety belt 6 is provided between the plurality of slide rollers 55 .
Wherein, the winder 2 is fixedly connected with the mounting seat 1, and the mounting seat 1 is mounted on the automobile through the cooperation of a plurality of mounting holes 11 and bolts.
