detailed description

In order to make the technical means, creative features, goals and functions achieved by the present invention clearer and easier to understand, the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments:

As shown in Fig. 1 to Fig. 4, the present invention proposes a kind of braces 1 adjustable spinal surgery lumbar exercise device, comprising: support board 2 and storage mechanism 6, storage mechanism 6 is installed on the support board 2, storage mechanism 6 uses For convolution or release strap 1.

In order to design a storage mechanism 6 with a simple structure, and to be able to locate the length of the strap 1 protruding from the moving seat 23, the storage mechanism 6 includes: a reel 61, a coil spring 62 and a rotation limiting assembly 63, the reel 61 is used to roll up the strap 1, The reel 61 can be rotatably installed in the support plate 2, the support plate 2 is equipped with a central post extending into the reel 61, a coil spring 62 is installed between the central post and the inner wall of the reel 61, and the elastic force of the coil spring 62 The back strap 1 can be kept in the support plate 2, and the limited rotation assembly 63 is installed at the connection between the support plate 2 and the coiling drum, and the limited rotation assembly 63 is used to limit the rotation of the reel 61.

In order to ensure that the support plate 2 can be closely attached to the human body after the back strap 1 is carried, thereby adjusting the distance between the moving seat 23 and the plate body 21, the support plate 2 includes: a plate body 21, a moving rod 22, a moving seat 23 and a positioning assembly. The plate body 21 is used to install the end of the braces 1 away from the reel 61, the plate body 21 is equipped with a movable moving rod 22, and a positioning assembly is installed at the connection between the moving rod 22 and the plate body 21, and the positioning assembly is used to limit the movement The rod 22 moves relative to the plate body 21 , the moving seat 23 is fixed on the moving rod 22 , and the storage mechanism 6 is installed in the moving seat 23 .

In order to adjust the strap 1 conveniently, the adjustment of the positioning assembly can be realized by adjusting the rotation limiting assembly 63, which is connected with the positioning assembly.

In order to design the rotation limiting assembly 63 with a simple structure, the rotation limiting assembly 63 includes: a toggle lever 631, an intermediate lever 632, a reset part 633, a first block 634 and a gear ring 635, and the toggle lever 631 is movably installed on the moving seat 23, the toggle lever 631 is connected with an intermediate rod 632 located in the movable seat 23 and the movable rod 22, the intermediate rod 632 is connected to the inner wall of the movable seat 23 through the reset part 633, the intermediate rod 632 is fixed to the first block 634, the first The block 634 can engage with the gear ring 635 , and the gear ring 635 is fixed to one end of the reel 61 . The reset part 633 is a fifth spring.

In order to design a positioning assembly with a simple structure, the positioning assembly includes: a second clamping block 241 and a second rack 532, the second rack 532 positioned at the side of the moving rod 22 is installed in the moving seat 23, the second rack 532 can be connected with The second locking block 241 is engaged, and the second locking block 241 is fixed to the middle rod 632 .

When it is necessary to adjust the pull-out length of the strap 1 and the position of the moving seat 23, squeeze the toggle lever 631 so that the first block 634 is separated from the gear ring 635, and the second block 241 is separated from the second rack 532. Pulling out the strap 1 or retracting the strap 1 can also move the distance between the moving seat 23 and the plate body 21 .

When the toggle lever 631 is released, under the elastic force of the reset part 633, the first clamping block 634 engages with the gear ring 635, and the second clamping block 241 engages with the second rack 532, thereby realizing the gap between the moving seat 23 and the plate body 21. The distance will not change easily, and the length that the strap 1 stretches out from the mobile seat 23 will not change easily.

The adjustable lumbar exercise device for spinal surgery with strap 1 also includes: strap 1, mounting base 3, anti-off mechanism 4 and trigger mechanism 5, an insert is fixed at the end of strap 1 away from reel 61, and the insert is inserted into mounting base 3 Inside, an anti-off mechanism 4 is installed at the mounting seat 3.
