Detailed Description

Specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the seat cushion adjusting structure of the utility model comprises a shell 1, a worm wheel 2 and a worm 3 which are matched with each other are rotationally arranged in the shell 1, the worm wheel 2 is rotationally arranged in the shell 1 through a rotating shaft 4, one end of the worm 3 extends out of the shell 1, and one edge of the worm wheel 2 extends out of the shell 1 upwards and is provided with a fixing structure for fixing a seat cushion 5.

In actual production, the fixing structure may be the following structure: the fixing structure comprises a fixing block 6 which is arranged on the edge of the worm wheel 2 extending out of the shell and is approximately U-shaped, two ends of the fixing block 6 are respectively connected with a screw in a threaded mode, namely a first screw 7 and a second screw 8, and a fixing rod 9 on the seat cushion 5 is located between two ends of the fixing block 6 and is fixed through the first screw 7 and the second screw 8 at two ends of the fixing block 6.

As shown in fig. 2, in actual production, the fixing rod 9 on the seat cushion 5 is generally U-shaped, and the end of the first screw 7 extends from the U-shaped bottom of the fixing rod 9 and abuts against the U-shaped bottom of the fixing rod 9, that is, the end of the first screw 7 is embedded in the U-shaped bottom of the fixing rod 9. Two sleeves 10 are fixed on the fixed block 6, two ends of the fixed rod 9 extend into the sleeves 10 respectively, a fixed push rod 11 which is approximately U-shaped is connected to the second screw 8 in a rotating threaded mode, and two ends of the fixed push rod 11 extend into the sleeves 10 respectively and are propped against two ends of the fixed rod 9 respectively.

In order to facilitate the operation by one hand, the end of the worm 3 extending out of the shell 1 is fixed with a knob 12. It is of course also possible to produce the worm 3 without extending beyond the housing 1, the knob 12 being fixed to the worm 3, the knob 12 being the end of the worm 3 extending beyond the housing 1.

In order to further prevent the angle of the seat cushion 5 from changing due to the fact that the rider sits on the seat cushion 5 and forces the worm wheel 2 and the worm 3 to rotate, the knob 12 is connected with a movable sleeve 13 through a spline, namely the movable sleeve 13 and the knob 12 can move relatively in the axial direction, the movable sleeve 13 is connected with a base 14 through threads, and the base 14 is fixed on the shell 1. The threaded connection of the movable sleeve 13 and the base 14 is used for further preventing the worm 3 from rotating, namely achieving the purpose of self-locking.

The working process of the utility model is as follows: as shown in fig. 1, the seat cushion adjusting mechanism of the present utility model is fixed to the saddle pipe 15, that is, the housing 1 is fixed to the saddle pipe 15. When the front and rear positions of the seat cushion 5 are required to be adjusted, the seat cushion 5 is adjusted to the proper position by loosening the first screw 7 and the second screw 8 by a tool, the second screw 8 is rotated, and the fixing push rod 11 moves leftwards or rightwards under the action of the second screw 8 until abutting against the end part of the fixing rod 9 on the seat cushion 5, and simultaneously the first screw 7 is screwed, so that the seat cushion 5 is fixed at the required position in front and rear. Since the first screw 7 and the second screw 8 are horizontally arranged, the first screw 7 and the second screw 8 are not limited by the narrow operation space when operated, and the operation is convenient. When the angle of the seat cushion 5 needs to be adjusted, only the knob 12 needs to be rotated. The worm 3 rotates under the action of the knob 12, so that the worm wheel 2 rotates anticlockwise or clockwise, and the seat cushion 5 also rotates anticlockwise or clockwise due to the fact that the seat cushion 5 is fixed on the worm wheel 2, and therefore the adjustment of the angle of the seat cushion 5 is achieved very conveniently. The operation of the child and the adult can be carried out by one hand, which is very convenient. In addition, the worm wheel 2 and the worm 3 have certain self-locking function, so that the seat cushion 5 is not worried about the change in angle caused by the rotation of the worm 3 of the worm wheel 2 due to the weight of a rider and the like.
