The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] like Figure 1-3As shown, a guard-type support bar comprises at least one gasket 1, a left guard bar 2, a right guard bar 3, an upper support bar 4 and a lower support bar 5 of the same thickness, the gasket 1 is laid on the left side wall and / or the right side wall of the bottom end of the upper support bar 4, the left guard bar 2 is arranged on the left side of the bottom end of the upper support bar 4, the right guard bar 3 is arranged on the right side of the bottom end of the upper support bar 4, and is parallel to the left guard bar 2, the top end of the left guard bar 2 and the top end of the right guard bar 3 clamp the bottom end of the upper support bar 4 and the gasket 1 therein, and are both fixedly connected to the bottom end of the upper support bar 4, a transfer shaft 6 is connected between the bottom end of the left guard bar 2 and the bottom end of the right guard bar 3, the top end of the lower support bar 5 can be rotatably sleeved on the transfer shaft 6, and when in use, the upper support bar 4 is fitted and installed on the user's wrist through other devices. At the leg, the lower support bar 5 is installed at the user's calf through other devices to adapt to the user's leg joint movement, and because the gasket 1 is installed between the bottom end of the upper support bar 4 and the left guard plate 2 and the right guard plate 3, the distance between the inner wall of the left guard plate 2 and the inner wall of the right guard plate 3 is equal to the sum of the thickness of the upper support bar 4 and the thickness of the gasket 1, and this value is greater than the thickness of the lower support bar 5. Therefore, it can effectively avoid the gap between the left guard plate 2 and the right guard plate 3 being too small, and prevent the lower support bar 5 from having difficulty in rotating, so as to ensure the smooth rotation of the lower support bar 5. It should be noted that the utility model can be applied not only to leg orthopedics, but also to arm orthopedics, such as upper arms and forearms, and the principle is the same as above.

[0026] In one embodiment, the left protective plate 2, the right protective plate 3 and the upper support bar 4 are all made of metal, and the three can be fixedly connected by welding (not shown in the drawings).

[0027] Furthermore, the thickness of the gasket 1 is 0.02 mm-0.1 mm. The ultra-thin gasket 1 can provide a smooth rotation gap for the lower support bar 5, and can also ensure the overall installation accuracy and transmission stability of the guard plate type support bar.

[0028] Furthermore, the bottom end of the upper support bar 4 , the gasket 1 , the top end of the left protective plate 2 and the top end of the right protective plate 3 are riveted together by means of rivets 7 .

[0029] Furthermore, two rivets 7 are provided and distributed along the length direction of the upper support bar 4 .

[0030] Furthermore, the bottom end of the left guard plate 2 is bent toward the rear side, the right guard plate 3 is symmetrical with the left guard plate 2, a first inclined surface 41 is provided on the bottom end wall of the upper support bar 4, a contact portion 51 is provided at the top end of the lower support bar 5, and a second inclined surface 52 is provided on the side of the contact portion 51 facing the upper support bar 4. When the lower support bar 5 swings around the transfer shaft 6 so that the distance between its bottom end and the top end of the upper support bar 4 reaches a maximum value, the second inclined surface 52 will abut against the first inclined surface 41 to limit the further swing of the lower support bar 5, so as to control the rotation of the lower support bar 5 within a reasonable range, adapt to the user's leg straightening state, and avoid over-swing.

[0031] Furthermore, a vertical surface 53 is provided on the outward side of the abutment portion 51, and a slidable drop ring 8 is commonly sleeved on the top of the left guard plate 2 and the top of the right guard plate 3. When the user's knee joint needs to be braked, the user can first straighten the leg to abut the second inclined surface 52 with the first inclined surface 41, and then slide the drop ring 8 down to abut the bending part of the left guard plate 2 and the bending part of the right guard plate 3, so that the inner wall of one side of the drop ring 8 is slidably connected with the vertical surface 53, thereby limiting the further swing of the lower support bar 5 through the first inclined surface 41, and limiting the reset swing of the lower support bar 5 by using the inner wall of one side of the drop ring 8, so that the lower support bar 5 and the upper support bar 4 are relatively fixed, so that the guard plate type support bar can maintain the maximum length of the straightened state to achieve a locking effect.

[0032] Furthermore, the adapter shaft 6 includes a nail nut 61 and a screw 62. The tip of the nail nut 61 passes through the right guard plate 3, the top of the lower support bar 5 and the left guard plate 2 in sequence from the outer side of the right guard plate 3. The top of the lower support bar 5 is rotatably connected to the nail nut 61. The head of the nail nut 61 abuts against the outer wall of the right guard plate 3. The screw 62 is screwed to the nail nut 61. The head of the screw 62 abuts against the outer wall of the left guard plate 2, so that the bottom end of the left guard plate 2, the top of the lower support bar 5 and the bottom end of the right guard plate 3 are connected by the screw 62 and the nail nut 61 being screwed toward each other, thereby reducing the difficulty of installing the lower support bar 5 and facilitating the disassembly and replacement of the lower support bar 5.

[0033] Furthermore, a receiving groove (not shown in the drawings) is provided on the outer wall of the right guard plate 3, and the head of the nail nut 61 is located in the receiving groove. Specifically, when in use, the right guard plate 3 is placed close to the human body, and the head of the nail nut 61 is stored in the receiving groove, which is beneficial for the outer wall of the right guard plate 3 to remain flush, so as to avoid irregular protrusions affecting the comfort when used close to the body.
