[0026] Please refer to Figures 1-7The utility model provides an angle adjustable footrest, install on wheelchair, including footrest connecting pipe 1, footrest body 2, locking pipe 3, adjusting column 4 and support plate 5, the end of footrest body 2 rotatablely install on footrest connecting pipe 1, locking pipe 3 fixedly connected on footrest connecting pipe 1 and located the below of footrest body 2, locking pipe 3 includes the adjusting section 31 and locking section 32 of interconnection, adjusting column 4 installs in locking pipe 3 and movable relative to locking pipe 3, locking section 32 inside along the circumferential even multiple limit slot 321 is provided with, the end of adjusting column 4 cooperation limit slot 321 is provided with multiple limit teeth 41, the adjusting section 31 is provided with the avoidance slot 311, the one side of support plate 5 passes through the avoidance slot 311 and is fixedly connected with adjusting column 4, the other side of support plate 5 and the lower surface of footrest body 2 are opposite and hold, after sliding adjusting column 4 makes limit tooth 41 with limit slot 321 separate, adjusting column 4 can rotate relative to locking pipe 3, and then drive support plate 5 relative avoidance slot 311 rotate.

[0027] The angle adjustable footrest of the utility model, adjusting column 4 is inserted in locking pipe 3, and limit tooth 41 and limit slot 321 are mutually matched, at this moment, under the cooperation of limit tooth 41 and limit slot 321, adjusting column 4 cannot rotate relative to locking pipe 3, thereby making adjusting column 4 and locking pipe 3 relatively fixed, therefore, the position of support plate 5 is fixed in the specific position, at this moment, rotating footrest body 2, footrest body 2 is supported on support plate 5 under the action of gravity, and support plate 5 plays the supporting role to footrest body 2.

[0028] When needing to adjust the angle of footrest body 2, the limit tooth 41 on the adjusting column 4 is separated from the limit slot 321 of the locking section 32 by pulling the adjusting column 4 outward, and at the same time, the support plate 5 moves in the avoidance slot 311 along the axial direction of the locking pipe 3. When the limit tooth 41 is separated from the limit slot 321, the limit tooth 41 is located in the adjusting section 31 and can move in the adjusting section 31. At this time, the user rotates the adjusting column 4, thereby driving the support plate 5 to rotate in the avoidance slot 311. When the angle of the support plate 5 is adjusted to the right position, the adjusting column 4 is pushed inward, so that the limit tooth 41 is inserted into the limit slot 31 again, thereby locking the adjusting column 4 on the locking pipe 3, and thereby realizing the fixing effect of the support plate 5. At this time, when the footrest body 2 is supported on one side of the support plate 5, the inclination angle of the footrest body 2 can be adjusted.

[0029] Please refer to Figure 1 The footrest connecting pipe 1 is fixedly connected with the wheelchair frame of the wheelchair, thereby fixing the footrest of the utility model on the wheelchair. The footrest connecting pipe 1 is substantially in the shape of an inverted U, including a horizontal pipe and vertical pipes connected to both ends of the horizontal pipe. The footrest body 2 is substantially in the shape of a rectangular flat plate. The opposite ends of one side of the footrest body 2 protrude connection ears 21. The connection ears 21 and the vertical pipes of the footrest connecting pipe 1 are rotatably connected through a pin shaft 11.

[0030] Please refer to Figure 2 The locking tube 3 is fixedly connected to the lower end of the longitudinal tube of the foot pedal connecting tube 1, and has a substantially tubular structure with both ends penetrating through. An adjusting section 31 and a locking section 32 are coaxially arranged. The outer diameter of the adjusting section 31 is the same as that of the locking section 32, and the wall thickness of the adjusting section 31 is smaller than that of the locking section 32. Therefore, a stepped surface 322 is formed on the side of the locking section 32 close to the adjusting section 31, and a limiting groove 321 is recessed from the stepped surface 322 along the axial direction of the locking section 32.

[0031] The adjusting column 4 has a substantially cylindrical structure, and the outer diameter of the adjusting column 4 is the same as the inner diameter of the locking section 32. When the end of the adjusting column 4 is inserted into the locking section 32, the limiting teeth 41 are inserted into the limiting groove 321, thereby limiting the rotation of the adjusting column 4.

[0032] The limiting groove 321 has a substantially triangular structure, and a plurality of limiting grooves 321 are connected end to end.

[0033] As a preferred embodiment, the locking section 32 has two, and is respectively connected to the opposite ends of the adjusting section 31. The locking section 32 is fixedly connected to the foot pedal connecting tube 1. The limiting groove 321 arranged at one end of the locking tube 3 corresponds to the limiting groove 321 arranged at the other end of the locking tube 3. Correspondingly, the limiting teeth 41 are arranged at both ends of the adjusting column 4. In actual use, when the adjusting column 4 is moved along the axial direction of the locking tube 3, the limiting teeth 41 at both ends are simultaneously engaged with or separated from the corresponding limiting grooves 321. In this way, the two locking sections 32 are arranged to limit the opposite ends of the adjusting column 4, thereby improving the locking stability between the adjusting column 4 and the locking tube 3.

[0034] In addition, one end of the adjusting column 4 is outwardly protruded along the radial direction of the adjusting column 4 to form a limiting flange 42. The outer diameter of the limiting flange 42 is greater than the outer diameter of the locking tube 3. When the adjusting column 4 is installed in place, the limiting flange 42 abuts against the end surface of the locking tube 3, thereby limiting the adjusting column 4, and facilitating the user to quickly install the adjusting column 4 in place. Further, the limiting flange 42 has a circular plate structure, and a groove 421 is arranged on the outer circumferential surface of the limiting flange 42. When the user installs the adjusting column 4, the limiting flange 42 can be held to move the adjusting column 4. The arrangement of the groove 421 increases the friction between the limiting flange 421 and the palm, which is beneficial to the user to stably hold the limiting flange 42.

[0035] Furthermore, the length of the adjusting column 4 is less than the length of the locking tube 3. A bolt 43 is threadedly connected to the end of the adjusting column 4 away from the limiting flange 42. The tail of the bolt 43 is threaded to the adjusting column 4, and the head of the bolt 43 abuts against one end of the locking tube 3. After the adjusting column 4 is installed in place, the user can install the bolt 43 at one end of the adjusting column 4. Due to the length difference between the adjusting column 4 and the locking tube 3, during the tightening of the bolt 43, the head of the bolt 43 will abut against the end face of one end of the locking tube 3. In this way, the adjusting column 4 is fixed on the locking tube 3 and cannot easily move axially, preventing the adjusting column 4 from separating from the locking tube 3.

[0036] The clearance groove 311 is roughly rectangular in shape. The length of the clearance groove 311 is greater than the width of the support plate 5, and the width of the clearance groove 311 is greater than the thickness of the support plate 5, so as to ensure that the support plate 5 can move axially within the clearance groove 311 and rotate circumferentially within the clearance groove 311, so as to control the tilt angle of the support plate 5.

[0037] The side of the support plate 5 away from the foot pedal body 2 is set as an arc surface, and this arc surface fits into the outer peripheral surface of the adjustment column 4 to increase the connection area between the two and improve the connection stability. In addition, the support plate 5 and the adjustment column 4 can be fixedly connected by fasteners such as screws.

[0038] This utility model also provides a wheelchair, which includes the aforementioned angle-adjustable footrests. During installation, the footrest connecting tube 1 is fixedly connected to the wheelchair frame.

[0039] The adjustable foot pedal or wheelchair provided by this utility model allows users to move the support plate 5 by inserting, unplugging, and rotating the adjusting column 4, thereby adjusting the tilt angle of the support plate 5 and thus adjusting the angle of the foot pedal body 2. This meets the needs of different users, greatly improves the user experience, and the mutual cooperation between the limiting tooth 41 and the limiting groove 321 ensures a stable locking relationship between the two. The operation is simple and convenient, and it is suitable for widespread use.
