[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figures 1 to 6 As shown, the upper arm support with a protective structure of the present invention includes a connecting component 10, on which an arm support component 20 is arranged, on which a rotating component 30 is arranged, on which a locking component 40 is arranged, and the locking component 40 is used to lock the rotating component 30 to prevent the rotating component 30 from rotating at will.

[0033] like Figure 1 and Figure 2 As shown, the connecting assembly 10 includes an inner ring 11 and an outer ring 12, and the inner ring 11 and the outer ring 12 are rotatably connected so that the inner ring 11 can rotate. In this embodiment, the shape of the outer ring 12 is circular. In other embodiments, the shape of the outer ring 12 can be square or triangular, etc.

[0034] In one embodiment, the outer surface of the inner ring 11 has a rotating portion 111, and the inner surface of the outer ring 12 has a third groove 121. The outer ring 12 can be divided into an upper and lower part, which are spliced ​​together by bolts or snaps to facilitate the installation of the inner ring 11, so that the rotating portion 111 on the outer surface of the inner ring 11 is snapped into the third groove 121 on the outer ring 12. The shape of the third groove 121 is circular. The above structure can realize the rotation of the inner ring 11 in the outer ring 12.

[0035] like Figure 1 As shown, the arm support assembly 20 includes a mounting frame 21 , a protrusion 22 , a screw rod 23 , a first connecting rod 24 , a second connecting rod 25 , an arm support body 26 , a protective portion 27 and a fixing member 28 .

[0036] Specifically, the bottom of the mounting frame 21 has two protrusions 22, the two protrusions 22 are symmetrically arranged, and a screw rod 23 is movably connected in the middle of the two protrusions 22, and a first connecting rod 24 is movably connected to the outer surface of the screw rod 23, the first connecting rod 24 can rotate on the screw rod 23, and a second connecting rod 25 is movably connected to the outer surface of the first connecting rod 24, and threaded holes are provided on the outer surfaces of the first connecting rod 24 and the second connecting rod 25, so that the fixing member 28 can be installed in the threaded holes on the first connecting rod 24 and the second connecting rod 25. Specifically, the fixing member 28 is a bolt, and the second connecting rod 25 is installed on the first connecting rod 24 by the bolt. Through the above structure, the disassembly of the second connecting rod 25 is convenient, and the second connecting rod 25 can be swung by the rotational connection between the first connecting rod 24 and the screw rod 23.

[0037] An arm support body 26 is provided at the bottom end of the second connecting rod 25. Protective parts 27 are provided on both sides of the arm support body 26. The protective parts 27 are arc-shaped and are used to fit with human arms. The protective parts 27 have through holes for installing straps, through which the human arm can be fixed to the arm support body 26.

[0038] like Figure 1 and Figure 3 As shown, the rotating assembly 30 includes a mounting frame 31 connected to the outer surface of the outer ring 12 by bolts, and the mounting frame 31 has a slot 311, a rotating rod 312 is fixedly connected in the slot 311, and a gear 313 is fixedly connected to the outer surface of the rotating rod 312. In addition, a rotating member 314 is fixedly connected to the top of the rotating rod 312, and a rotating disk 315 is movably connected to the outer surface of the rotating member 314. The bottom of the rotating disk 315 also has a mounting portion 3151, so that the rotating member 314 and the rotating disk 315 can rotate relative to each other.

[0039] like Figures 3 to 5As shown, the locking assembly 40 includes a first mounting member 41 and a second mounting member 42 fixed on the mounting portion 3151. The second mounting member 42 is movably arranged inside the first mounting member 41 and is flush with the top of the first mounting member 41. Specifically, the second mounting member 42 is installed in the first mounting member 41 by bolts to facilitate disassembly between the first mounting member 41 and the second mounting member 42.

[0040] The locking assembly 40 also includes a fixed block 43 fixed at the bottom of the second mounting member 42, and one side of the fixed block 43 has a long rod 431, the long rod 431 is cylindrical in shape, and an elastic member 432 is arranged on the outer surface of the long rod 431, and a moving member 433 is also slidably connected to the outer surface of the long rod 431, and one side of the moving member 433 is fixedly connected to a connecting plate 434, one side of the connecting plate 434 has a first groove 4341, one side of the connecting plate 434 has teeth 4342 extending outward, and the teeth 4342 can be meshed with the gear 213, and the lower surface of the connecting plate 434 is also fixedly connected to a mounting plate 435, one side of the mounting plate 435 has a slide 4351, and the shape of the slide 4351 is arc-shaped.

[0041] In addition, a screw 47 is threadedly connected to the lower surface of the second mounting member 42, and the screw 47 is located in the first groove 4341. A blocking rod 44 is rotatably connected to the outer surface of the screw 47. The blocking rod 44 has a contact portion 441 on the side close to the mounting plate 435, and the contact portion 441 is slidably connected to the slide 4351. When the blocking rod 44 is rotated clockwise, the contact portion 441 of the blocking rod 44 will abut against the slide 4351 and push the slide 4351 to move, so that the teeth 4342 on the connecting plate 434 engage with the gear 213, limit the gear 213, and prevent the gear 213 from rotating, thereby locking the rotating rod 212 to prevent the rotating rod 212 from rotating, thereby avoiding the problem that the rotation angle of some patients may cause damage to the patient's arm.

[0042] like Figures 3 to 6 As shown, the first mounting member 41 is provided with a moving hole for moving the blocking rod 44, so that the blocking rod 44 can move along the moving hole, and a receiving groove 442 is provided on the lower surface of the blocking rod 44, and a mounting tube 46 is fixedly connected to the inner bottom wall of the first mounting member 41, and the mounting tube 46 is located directly below the receiving groove 442. The top of the mounting tube 46 has a second groove 461, and the inner wall of the second groove 461 is provided with an elastic part 462, and the top of the elastic part 462 is fixedly connected with a limiting member 463, and the limiting member 463 is semi-spherical. The elastic force of the elastic part 462 on the limiting member 463 upward causes the limiting member 463 to enter the receiving groove 442, thereby limiting the blocking rod 44. It should be noted that when the limiting member 463 enters the receiving groove 442, the teeth 4342 on the connecting plate 434 and the gear 213 are in a meshing state, that is, a locked state.

[0043] Working principle: when unlocking is required, the blocking rod 44 is rotated counterclockwise, and the blocking rod 44 will drive the limiting part 463 to move downward into the groove. At this time, the blocking rod 44 is released, and the spring will push the moving part 433 away from the gear 213. At this time, the teeth 4342 on the connecting plate 434 are away from the gear 213, unlocking the gear 213, and then the rotating rod 212 can be controlled to rotate to adjust the angle of the arm support body 26.

[0044] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
