Detailed ways
As shown in the figure, the pressure regulating retractor disclosed by the present utility model includes a retractor body 1, and a webbing 3, one end of which is mounted on the retractor body 1, and the other end is fixed on the automobile through a fixing ring 2. The movable tab 4 on the webbing 3 is installed on the car 5 that matches the movable tab 4; the retractor body 1 is provided with a webbing elastic adjustment mechanism 6, and the webbing tension adjustment mechanism 6 is installed on the retractor body 1 A rack 7 is added on the rack 7, the rack 7 is equipped with a gear shaft, that is, a spline shaft 8, the rotating shaft 9 of the retractor body 1 for winding the webbing 3 is lengthened and equipped with a driving gear 10, and the spline shaft 8 of the rack 7 is mounted on the top. There is a driven gear 11 meshing with the driving gear 10; the frame 7 is also equipped with a gear shaft rotation angle controller 12 that controls the rotation angle of the spline shaft 8; the gear shaft rotation angle controller 12 is a device mounted on the frame 7. The casing 13 is equipped with a sliding shaft 14 that can slide in the axial direction. The sliding shaft 14 is fixedly equipped with an iron disc 15 and a rotation angle control rod 16 that can be magnetically attracted by an electromagnet. The blocking rod 17 for the rotation of the angle control rod 16; the first electromagnet 18 and the second electromagnet 19 for attracting the iron disc 15 are installed in the casing 13 in front of the two sides of the iron disc 15, and the first electromagnet 18 and the second electromagnet 19 are installed at a position 180° apart.

The working principle of the utility model is as follows: after people sit on the car seat, they wear the webbing on the chest as usual, and insert the movable tabs mounted on the webbing into the buckles mounted on the car. At this time, the webbing is close to people’s chest and abdomen. If the webbing is not close to people’s chest and abdomen, it is necessary to loosen the webbing and press the first electric button. At this time, the electromagnet is instantly energized to generate a magnetic suction iron. If the gear shaft is a spline shaft, the spline shaft will be automatically inserted into the spline groove of the sliding shaft; if the end of the gear shaft is a spline shaft The keyway, one end of the sliding shaft is a splined shaft, then the one end of the sliding shaft that has been slid over will be automatically inserted into the splined groove at the end of the gear shaft. At this time, the rotating shaft of the retractor body for winding the webbing is integrated with the extended driving gear, the driven gear meshing with the driving gear, the gear shaft of the driven gear mounted on the frame, and the sliding shaft installed in the casing, and the sliding The rotation angle control lever on the shaft rotates in the counterclockwise or clockwise direction and is blocked by the blocking rod installed longitudinally in the casing, so that the above-mentioned whole cannot make the retractor body rotate in the direction of tightening, so the tension is loose. The webbing will no longer be tightened by the retractor body; if the webbing is loose enough, the webbing can be loosened, but the length of the webbing can only be loosened by rotating the angle control lever clockwise or counterclockwise. One rotation of the retractor body rotates to release the length of the webbing. If the seat belt is tightened, press the second electric button, at this time the second electromagnet is instantly energized, attracting the iron disc, so that the sliding shaft of the iron disc slides and disengages from the inserted gear shaft, then the coil The body of the receiver returns to an independent working state; if you want to remove the seat belt, when you press the buckle, the third electric button installed in the buckle is turned on, and the second electromagnet is instantly energized, attracting the iron disc. , so that the sliding shaft of the iron-loading disc slides and is disengaged from the inserted gear shaft, and the retractor body also returns to an independent working state.
The utility model is simple in structure and reasonable in design. People wear it on the car without feeling of being bound, and the chest and abdomen will not feel oppressed, which is safe and comfortable; the tightness of the seat belt is automatically adjusted by buttons, and the operation is simple. It is convenient; and the tightness state will not change after adjustment, which is stable and reliable.
