Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1-5, a quick-release seat structure for an electric wheelchair comprises a seat 1 and a wheelchair frame 2, wherein a fixed sleeve 3 is fixedly arranged on the front side of the lower end surface of the seat 1, two fixed seats 4 are also fixedly arranged on the lower end surface of the seat 1, clamping rods 5 are fixedly arranged on the fixed seats 4, the fixed seats 4 are U-shaped structures, and the clamping rods 5 are fixedly arranged in openings of the fixed seats 4. Fixed joint seat 6 that is equipped with on the wheelchair frame 2, joint seat 6 and fixing base 4 one-to-one are equipped with a joint groove 7 that sets up towards seat 1 front side on the joint seat 6, joint seat 6 is including the supporting shoe 8 of horizontal setting, and 8 fixed trips 9 that are buckled towards supporting shoe 8 front side that are equipped with in supporting shoe 8 up end rear side, and the space between trip 9 and the supporting shoe 8 is as joint groove 7. The front end of the supporting block 8 is fixedly provided with a limiting bulge 10, and a gap is reserved between the clamping hook 9 and the limiting bulge 10. The clamping rods 5 are embedded into the clamping grooves 7 on the corresponding clamping seats 6.

The wheelchair is characterized in that the wheelchair frame 2 is provided with a connecting rod 11, the front end of the connecting rod 11 is provided with a screw hole 12, the front end of the connecting rod 11 is sleeved with the fixing sleeve 3, one side of the fixing sleeve 3 back to the connecting rod 11 is provided with a knob 13, and the knob 13 is fixedly provided with a screw 14 connected with the screw hole 12 in a threaded manner. One end of the connecting rod 11, which is back to the fixed sleeve 3, is hinged with the wheelchair frame 2 through a rotating shaft 15, and when the clamping rod 5 is embedded into the clamping groove 7, the clamping rod 5 and the rotating shaft 15 are positioned on the same straight line; be equipped with electric putter 16 between connecting rod 11 and the wheelchair frame 2, the fixed articulated seat 17 that is equipped with on the connecting rod 11, electric putter 16's cylinder body is articulated with articulated seat 17, and electric putter 16's piston rod is articulated with wheelchair frame 2.
