[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-8 The present invention provides the following technical solution.

[0037] Example 1: To address the problem in existing wheelchairs where the backrest and push handles are mostly welded to the wheel frame, making installation, disassembly, and assembly inconvenient, this example provides a detachable push handle wheelchair. The wheelchair includes a mounting bracket 1, rear wheels 2, handwheel rings 3, a connecting bracket 4, a backrest bracket 5, a first spring 6, a first movable pin 7, a fixing hole 8, a front wheel 15, a mounting cylinder 16, an armrest push rod 17, a second spring 18, a second movable pin 19, and a second concealing cap 20. Rear wheels 2 are mounted on both the front and rear sides of the mounting bracket 1. The handwheel rings 3 are fixedly connected to the outer sides of the rear wheels 2. The backrest bracket 5 is inserted into the upper end of the mounting bracket 1, and the lower end has telescopically connected first movable pins 7 on both the front and rear sides for limiting movement. The first movable pins 7 drive the backrest bracket 5 to move within the mounting bracket 1. The upper end forms a detachable structure, and a connecting bracket 4 is welded to the right end of the mounting bracket 1. A front wheel 15 is installed at the lower right end of the connecting bracket 4. A first spring 6 is installed inside the lower end of the backrest bracket 5, and a first movable pin 7 is fixedly connected to the movable end of the first spring 6. The first movable pin 7 is inserted into a fixing hole 8 for positioning, and the fixing hole 8 is located on the left side of the upper end of the mounting bracket 1. Mounting cylinders 16 are welded to the front and rear ends of the left side of the mounting bracket 1, and an armrest push rod 17 is inserted into the middle of the mounting cylinder 16. A second spring 18 is installed inside the lower end of the armrest push rod 17, and a second movable pin 19 is fixedly connected to the movable end of the second spring 18. The second movable pin 19 is inserted into the left side of the upper end of the mounting cylinder 16, and the second movable pin 19 extends and retracts at the lower end of the armrest push rod 17. A second concealer cap 20 is fitted at the connection between the mounting cylinder 16 and the armrest push rod 17. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, during wheelchair assembly, the first movable pin 7 is pressed, causing it to rotate at the lower end of the backrest bracket 5. This presses against the first spring 6, causing it to elastically deform. The backrest bracket 5 is then directly inserted into the mounting bracket 1. When the backrest bracket 5 moves the first movable pin 7 to the position of the fixing hole 8, the first spring 6 returns to its elastic deformation, pushing the first movable pin 7 to engage directly in the fixing hole 8. The fixing holes 8 are evenly spaced on the left side of the mounting bracket 1. The first movable pin 7 is inserted into the corresponding fixing hole 8, allowing for height adjustment of the backrest bracket 5 and enabling installation positioning between the backrest bracket 5 and the mounting bracket 1. The mounting cylinder 16 is provided with front and rear... The armrest push rod 17 can be inserted into either the front or rear mounting cylinder 16 according to actual needs and user habits. When inserting, first press the second movable pin 19, which compresses the second spring 18, causing the second spring 18 to elastically deform. The second spring 18 extends and retracts at the lower end of the mounting cylinder 16. Then, insert the lower end of the armrest push rod 17 into the mounting cylinder 16. The second spring 18 returns to its elastic deformation, pushing the second movable pin 19 to engage with the upper end of the mounting cylinder 16, thus facilitating the installation and positioning of the armrest push rod 17. The disassembly and assembly operations are relatively convenient. Then, pull the second concealer cap 20 so that the second concealer cap 20 is fitted onto the connection between the mounting cylinder 16 and the armrest push rod 17 to conceal imperfections.

[0038] Example 2: To address the problems existing in the prior art, this example provides a detachable push handle for a sports wheelchair, equipped with a first concealer cap 9 and an armrest bracket 10. The first concealer cap 9 is fitted at the connection between the backrest bracket 5 and the mounting bracket 1. The armrest bracket 10 is located at the right end of the backrest bracket 5, and the armrest bracket 10 is fixed to the backrest bracket 5 and the connecting bracket 4 by bolts. Figure 1 , Figure 2 and Figure 5 As shown, pulling down the first concealer cap 9, which is fitted onto the lower end of the backrest bracket 5, causes the first concealer cap 9 to move downward and fit onto the connection between the backrest bracket 5 and the mounting bracket 1, thus concealing imperfections and increasing aesthetics. Then, the lower end of the armrest bracket 10 is engaged with the connecting bracket 4, and the upper end of the armrest bracket 10 is engaged with the backrest bracket 5. Finally, bolts are used to tighten and limit the connection between the armrest bracket 10 and the backrest bracket 5, as well as between the armrest bracket 10 and the connecting bracket 4, thus fixing the armrest bracket 10. The armrest bracket 10 provides reinforcement and protection for the wheelchair.

[0039] Example 3: To address the problem in existing technologies where wheelchairs rest directly on the ground via their wheels, resulting in limited contact area and a lack of auxiliary support components, this example provides a detachable push handle for a wheelchair. The wheelchair includes a fixing mechanism 11, symmetrically positioned on the front and rear sides of the lower end of a mounting bracket 1. The fixing mechanism 11 comprises a support rod 12, plastic anti-slip foot covers 13, and fixing bolts 14. The support rod 12 is telescopically connected to the front and rear sides of the lower end of the mounting bracket 1, with the plastic anti-slip foot covers 13 engaging at the lower end of each support rod 12. The support rod 12 is positioned relative to the mounting bracket 1 by fixing bolts 14, which are threadedly connected to both the support rod 12 and the mounting bracket 1. Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, by pushing the armrest bracket 10, the wheelchair is moved via the rear wheels 2 and the front wheels 15. When it reaches the corresponding position, the wheelchair is stationary. The person pushing the wheelchair can pull down the support rod 12, which slides between the support rod 12 and the mounting bracket 1. The support rod 12 moves the plastic anti-slip foot covers 13 downwards and onto the ground. Then, by rotating the fixing bolt 14, the support rod 12 and the mounting bracket 1 are limited, which can provide auxiliary support for the wheelchair. In addition, the plastic anti-slip foot covers 13 provide a good anti-slip effect, increase the contact area between the wheelchair and the ground, and improve the stability of the wheelchair.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
