Detailed ways

First of all, please refer to Figure 1 and Figure 2, the utility model mainly includes a positioning seat 1, a support frame 2, a tent frame 3 and a pivot unit 4, wherein:

The positioning seat 1 is provided with a first fixing part 11 and a second fixing part 12, and a fixing screw 13 is screwed between the first fixing part 11 and the second fixing part 12, so as to lock a positioning piece 14 to force Tighten the first fixing part 11, the first fixing part 11 can be matched and fixed on the wheelchair frame, and the second fixing part 12 is screwed with another fixing screw 15.

Support frame 2, it is fixed on the second fixing part 12 of positioning seat 1, and this support frame 2 one end is provided with joint part 21 (as shown in Figure 3), and this joint part 21 side periphery upper ring is provided with several circles The card slot 22 is provided with a boss 23 on the same side of the joint part 21, and a through hole 24 is provided on the boss 23, and a groove 25 is provided on the other side of the joint part 21, and runs through to the through hole 24.

The tent frame 3 is pivotally connected to the joint part 21 of the support frame 2. The tent frame 3 includes a plurality of sheet-shaped main struts 31 and side struts 32, wherein the main struts 31 and the side struts 32 are One end of each is provided with a joint part 33, and the joint parts 33 are penetrated with a through hole 34, and one side of the joint part 33 of the main struts 31 and the side struts 32 is equidistantly provided with four protrusions. grain 35, and the other side periphery of the joint part 33 of these main struts 31 is provided with a plurality of circular slots 36, and the other end of the main struts 31 and side struts 32 is covered with tarpaulin37.

The pivot unit 4 is set in the through holes 24 and 34 of the joint part 21 of the support frame 2 and the joint part 33 of the tent frame 3. The pivot unit 4 is provided with a screw hole 41, and the screw hole 41 is screwed into a The fixing pin 42 is further provided with an elastic component 43 on the fixing pin 42, and the elastic component 43 is a spring.

When assembling, as shown in Figure 3 and Figure 4, it utilizes the fixing screw 13 of pressing positioning seat 1 to lock a positioning piece 14 to fix the first fixing part 11 on the wheelchair frame A by pressing. A fixing screw 15 tightly fixes the support frame 2 on the second fixing part 12 of the positioning seat 1, and then sequentially fits the through holes 34 on the joint parts 33 of the main struts 31 and side struts 32 to the support on the boss 23 of the joint part 21 of the frame 2, and make the protrusion 35 on one side of each main pole 31 snap into the slot 36 on the other side of the adjacent main pole 31, and the outermost main pole 31 The protruding grain 35 is then snapped into the draw-in groove 22 of the joint portion 21 of the support frame 2, and the protruding grain 35 of the joint portion 33 of the side strut 32 can be snapped into the draw-in slot 36 of the other outermost main strut 31 ( As shown in Figure 5), the pivot unit 4 is inserted into the through hole 24 of the joint part 21 of the support frame 2 and the through hole 34 of the joint part 33 of the main struts 31 and the side struts 32, and then the After the elastic component 43 is placed in the groove 25 of the joint part 21 of the support frame 2, the fixing pin 42 is screwed into the screw hole 41 of the pivot unit 4 to fix it.
