[0002] Walkers are suitable for people with limited mobility or the elderly. As the number of elderly people in China increases and people's economic conditions improve, walkers are widely promoted and used in the market, and the variety of walkers is also increasing. In existing technologies, to facilitate the use of walkers for people of different heights, the handles on the walkers are made into a shell-adjustable structure for height adjustment, while the seat cushions on the walkers are directly mounted on the front and rear brackets of the walker, making it impossible to adjust the seat cushion height. When using a walker of different heights, people need to choose a walker of correspondingly lower height, which reduces the scope of use. To this end, a walker with an adjustable seat cushion is proposed to adapt to people of different heights. Summary of the Invention

[0005] Preferably, an elastic member is installed in the roller bracket; and a limiting boss for adjusting and limiting the front frame and the rear frame is provided on the elastic member.

[0006] Preferably, the front frame and the rear frame are both provided with a plurality of adjustment holes adapted to the limiting bosses.

[0007] Preferably, an adjusting tube and a locking screw for locking the adjusting tube can be adjustably mounted on the front frame.

[0008] Preferably, the adjusting tube is provided with a plurality of adjusting through holes.

[0009] Preferably, a handle and a brake handle are also installed on the adjusting tube.

[0010] Preferably, a folding frame is installed between the front frame and the rear frame.

[0011] The beneficial effects of the utility model are as follows: the roller bracket can be adjusted and installed on the front frame and the rear frame, so that the height of the front frame and the rear frame can be adjusted, thereby facilitating the adjustment of the height of the seat cushions on the front frame and the rear frame, thereby expanding the scope of use and improving the convenience of use;

[0012] The rear frame can be movably mounted on the U-shaped block of the front frame, so that the rear frame and the front frame are in a parallel state when folded, thereby reducing the volume after folding. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following further describes the walker with adjustable seat height according to the present invention with reference to the accompanying drawings.

[0020] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0021] See attached Figure 1-5As shown, in this embodiment, a walker with an adjustable seat height comprises a frame 1, a seat 2 mounted on the frame 1, and rollers 3; the frame 1 comprises a front frame 101 and a rear frame 102, and a roller bracket 103 adjustable and mounted on the front frame 101 and the rear frame 102 to fix the rollers 3; a U-shaped block 4 is mounted on the front frame 101 and the rear frame 102 for movably connecting to reduce the folding volume of the front frame 101 and the rear frame 102; and the rollers 3 are mounted on the front frame 101 and the rear frame 102 to reduce the folding volume of the front frame 101 and the rear frame 102. The bracket 103 is adjustably mounted on the front frame 101 and the rear frame 102, and the height of the front frame 101 and the rear frame 102 is adjusted, thereby facilitating the adjustment of the height of the seat cushion 2 on the front frame 101 and the rear frame 102, thereby expanding the scope of use and improving the convenience of use; the rear frame 102 is movably mounted on the U-shaped block 4 of the front frame 101, so that the rear frame 102 and the front frame 101 are in a parallel state when folded, thereby reducing the volume after folding.

[0022] See attached Figure 1-4 As shown, an elastic member 104 is installed in the roller bracket 103; a limiting boss 105 for adjusting and limiting the front frame 101 and the rear frame 102 is provided on the elastic member 104; the front frame 101 and the rear frame 102 are both provided with a plurality of adjustment holes 106 adapted to the limiting boss 105; when the front frame 101 and the rear frame 102 are sleeved on the roller bracket 103, the limiting boss 105 on the elastic member 104 of the roller bracket 103 is squeezed by the inner walls of the front frame 101 and the rear frame 102 and moves inward until the adjusting holes on the front frame 101 and the rear frame 102 are engaged. When 106 moves to the limiting boss 105, the limiting boss 105 has no squeezing force and is restored by its own elasticity, so that the limiting boss 105 is installed in the adjustment hole 106 on the front frame 101 and the rear frame 102, thereby limiting the installation of the front frame 101 and the rear frame 102 and the roller bracket 103. The limiting boss 105 is installed in the adjustment holes 106 at different heights on the front frame 101 and the rear frame 102, so as to adjust the height of the front frame 101 and the rear frame 102, and then adjust the height of the seat cushion 2 on the front frame 101 and the rear frame 102 to adapt to different people.

[0023] See attached Figure 1 、 5 As shown, the front frame 101 can also be adjustably mounted with an adjusting tube 5 and a locking bolt 6 for locking the adjusting tube 5; the adjusting tube 5 is provided with a plurality of adjusting through holes 501; the adjusting tube 5 is also mounted with a handle 502 and a brake handle 503; a folding frame 7 is also mounted between the front frame 101 and the rear frame 102; the locking bolt 6 passes through the adjusting through holes 501 at different heights on the adjusting tube 5 and locks the adjusting tube 5, thereby facilitating adjustment of the height of the adjusting tube 5 to accommodate use by people of different heights.
