DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4In this embodiment, a detachable leg support for a wheelchair includes a connecting rod 1, an adjusting mechanism 2 is arranged in the connecting rod 1, the adjusting mechanism 2 includes a mounting box 3 fixedly mounted on the upper surface of the connecting rod 1, the mounting box 3 is fixedly connected with an adjusting block 4, a first spring 5 is fixedly connected in the adjusting block 4, an end of the first spring 5 away from the adjusting block 4 is fixedly connected with a movable block 6, a slide groove 7 is provided in the movable block 6, an adjusting rod 8 inserted into the slide groove 7 is slidably connected to the front surface of the mounting box 3, an end of the movable block 6 away from the first spring 5 is fixedly connected with a clamping plate 9, a sliding rod 10 is slidably connected in the adjusting block 4, and a leg support 11 is fixedly connected to the outer peripheral wall of the sliding rod 10.
[0022] In this embodiment, a screw rod 12 is fixedly connected to the upper surface of the connecting rod 1 . In order to enable the user to install the connecting rod 1 through the screw rod 12 when the user needs to install the connecting rod 1 , a clamping plate 13 is fixedly connected to the left surface of the connecting rod 1 .
[0023] In this embodiment, a second spring 14 is fixedly connected inside the clamping plate 13, and a clamping ring 15 is fixedly connected to one end of the second spring 14 away from the clamping plate 13. By setting the clamping plate, the second spring 14 and the clamping ring 15, the installation effect between the connecting rod 1 and the wheelchair can be assisted.
[0024] In this embodiment, the slide groove 7 is adapted to the adjustment rod 8. In order to enable the adjustment rod 8 to move in the slide groove 7, thereby driving the clamping plate 9 to adjust the position, the sliding rod 10 is limited by the clamping plate 9, and the upper surface of the installation box 3 is slidably connected to the leg support 11.
[0025] It should be noted that the slide 7 is composed of two straight slides and one arc-shaped groove.
