[0022] A retractable Brownian frame lower limb traction frame, the traction frame 10 includes a first frame body 11 located at the front end and a second frame body 12 located at the rear end, the first frame body 11 and the second frame body 12 can be movably connected along a preset direction, and the preset direction is the length direction of the traction frame 10; so that the traction frame 10 has a telescopic function, and the first frame body 11 and the second frame body 12 are connected by a guide rail 112 and a guide groove 122, which is conducive to smooth movement.

[0023] Furthermore, a fixing member 20 is detachably installed between the first frame 11 and the second frame 12 so that the first frame 11 and the second frame 12 can be fixed to avoid the position change between the first frame 11 and the second frame 12 during use; and, a plurality of first grooves 111 are evenly distributed along a preset direction in the portion where the first frame 11 and the second frame 12 overlap; a plurality of second grooves 121 are evenly distributed along a preset direction in the portion where the second frame 12 and the first frame 11 overlap; and a fixing groove 13 is formed when the first groove 111 corresponds to the second groove 121.

[0024] Specifically, the fixing member 20 includes a pin 21, and the pin 21 can be inserted into the fixing groove 13. When the user needs to move the first frame 11 and the second frame 12, he only needs to pull out the pin 21, move it to the required position, and then insert the pin 21 into the fixing groove 13 to complete the position fixation between the first frame 11 and the second frame 12. Figure 1 and Figure 3 shown.

[0025] Furthermore, a support frame 14 is rotatably installed at the end of the first frame 11 away from the second frame 12, and an adjustment member 30 is provided between the support frame 14 and the first frame 11 for fixing the rotation angle of the support frame 14. At the same time, the support frame 14 is rotatably connected to the first frame 11 through an adapter frame 15, one end of the adapter frame 15 is rotatably connected to the first frame 11, and the other end is telescopically connected to the support frame 14. When the support frame 14 rotates, the support frame 14 and the adapter frame 15 will also be telescopically extended and retracted accordingly to adapt to the change in height when the support frame 14 rotates.

[0026] The adjusting member 30 mentioned in the above structure includes: a threaded rod 31, one end of the threaded rod 31 is rotatably connected to the support frame 14, and the other end extends into the first frame body 11; an adjusting nut 32 is rotatably mounted on the first frame body 11, and the adjusting nut 32 is threadably matched with the threaded rod 31, so that by rotating the adjusting nut 32, the adjusting nut 32 can extend the threaded rod 31 into or out of the first frame body 11, so that the threaded rod 31 moves forward and backward along the axial direction of the threaded rod 31, and the bottom of the support rod is pushed out or retracted through the forward and backward movement of the threaded rod 31, so that the support frame 14 and the first frame body 11 can rotate to adjust the angle. At the same time, an avoidance groove 141 is also provided at the bottom of the support frame 14. Since the threaded rod 31 will also rotate when the support frame 14 rotates, the avoidance groove 141 allows the threaded rod 31 to rotate without being blocked.

[0027] In addition, an annular positioning groove 131 is also provided in the fixing groove 13; the outer edge of the pin shaft 21 has an annular positioning protrusion 211 that fits with the annular positioning groove 131. When the pin shaft 21 is inserted into the fixing groove 13, the annular positioning protrusion 211 will be embedded in the annular positioning groove 131 to maintain the position of the pin shaft 21 and avoid the pin shaft 21 from detaching when unnecessary.

[0028] The material of the annular positioning protrusion 211 is a plastically deformable material, such as rubber, silicone, etc., so that when the pin shaft 21 is inserted or pulled out, the annular positioning protrusion 211 can adaptively shrink inward, and when it reaches the position of the annular positioning groove 131, it stretches and snaps into the annular positioning groove 131.

[0029] Furthermore, the end of the pin shaft 21 is also provided with a pulling piece 22 , so that the user can disengage the pin shaft 21 from the fixing groove 13 . The user can pull out the pin shaft 21 through the pulling piece 22 .

[0030] In addition, it should be noted that when the traction frame 10 is in use, it is necessary to wrap a bandage around the first frame 11 and the second frame 12, and then wrap a bandage around the support frame 14, so that the injured foot can be placed thereon. This is for reference in actual use of the product, and the specific method of use is common knowledge among those skilled in the art and will not be described in detail here.

[0031] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0032] Those skilled in the art should understand that the above embodiments are only for the purpose of clearly illustrating the present invention, and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present invention.
