detailed description

The invention will now be further described with reference to the accompanying drawings.

1-7, a seat weight adjustment display device includes a weight adjustment screw 1, a display body 2, a display dial 3, an eccentric bushing 4, an adjustment handle 5, a handle pin 6, a disc spring 7, a bearing 8, Flat pad 9 and seat cover 10.

The display main body 2 is composed of a display cover 21, a display internal gear 22 and a pointer 23. The display cover 21 is a cylindrical body, and a center of the center of the cover is provided with a cover through hole 211 for mounting the weight adjustment screw 1. The display internal gear 22 is mounted on the display cover 21, and the pointer 23 is disposed on the circumferential surface of the internal gear 22 of the display.

The display dial 3 is composed of a display dial external gear 31 and a display dial cover 32, and the display dial cover 32 is engraved with a scale line on the circumference of the disk surface. The outer surface of the display dial outer gear 31 is provided with a display dial outer gear through hole 311 for mounting the weight adjusting screw 1. The display dial cover 32 is a cylindrical body, and a dial cover through hole 321 is opened at the center of the circle. The display dial external gear 31 meshes with the display internal gear 22, and the display dial cover 32 is mounted on the display dial external gear 31.

The weight adjusting screw 1 is provided with a threaded section 11 , and the end of the weight adjusting screw 1 away from the threaded section 11 is a handle connecting section 12 , and the handle connecting section 12 is provided with a screw pin hole 121 , and the handle connecting section 12 is square on both sides The thickness of the handle connecting section 12 is smaller than the diameter of the weight adjusting screw 1, and the thickness of the end of the handle connecting section 12 is the smallest. The weight adjustment screw 1 is integrally formed.

The eccentric bushing 4 is composed of a small end ring and a big end ring.

The flat pad 9 and the bearing 8 are fixed to the seat damper mechanism, and the end portion 11 of the weight adjusting screw 1 is sequentially passed through the seat cover 10, the bearing 8 and the flat pad 9, and then assembled with the seat damper mechanism. The flat pad 9 has one end adjacent to the bearing 8 and the other end abutting the threaded section 11. The other end of the bearing 8 is connected to the seat cover 10.
