Description

Technical Field

[0001] This utility model relates to the field of protective gear technology, and in particular to adjustable protective gear. Background Technology

[0002] The wrist joint is a complex and important joint. With the development of joint surgery techniques, people have increasingly higher requirements for joint rehabilitation techniques. Traditionally, plaster cast immobilization is a common method for fixing fracture patients. The advantages of plaster cast immobilization are its rigidity and resistance to deformation and loosening. However, because the plaster cast is rigid and fits tightly to the limb, it is difficult to adapt to the reactive swelling of the limb after trauma, which can easily compress the limb and cause many complications. In addition, inappropriate immobilization can create an unfavorable biomechanical environment that leads to rotational dysfunction, easily causing compartment syndrome, nonunion of fractures, and may even lead to redislocation.

[0003] Therefore, wrist braces are often used to protect the wrist joint. However, the inventor found in his daily work that each user's wrist joint is of different size, and most of the standard braces are difficult to adapt to different users according to their needs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable protective gear.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable protective gear, including a wrist support frame, a back-of-hand support frame rotatably mounted on one side of the wrist support frame, and two cross-arranged pull ropes, the two ends of which are respectively connected to the wrist support frame and the back-of-hand support frame. The surface of the pull ropes is fitted with a tightening sleeve, wherein the pull rope connected to the wrist support frame extends into the interior of the wrist support frame, and an adjusting component is also included, wherein the adjusting component can adjust the length of the pull ropes.

[0006] Preferably, one side of the wrist support frame has an assembly groove, and one side of the back of the hand support frame is fixedly connected to a connecting block, which is rotatably assembled in the assembly groove.

[0007] Preferably, the wrist support and the user contact area are provided with a sponge pad, and the back of the hand support and the user contact area are provided with a sponge pad.

[0008] Preferably, the wrist support frame is equipped with fabric straps on both sides near the port, and the free ports of the two fabric straps are provided with corresponding Velcro straps.

[0009] Preferably, the adjusting component includes an assembly groove formed on the upper end of the wrist support frame, wherein a mounting post is fixedly mounted inside the assembly groove, and a ratchet is also included, wherein the ratchet rotates inside the assembly groove by means of the mounting post, and a pawl is slidably provided on the surface of the wrist support frame, wherein the pawl can slide into the assembly groove and be engaged on the surface of the ratchet, wherein one end of the pull rope extends into the assembly groove and tightens as the ratchet rotates.

[0010] Preferably, a rotating disk is provided at the port of the assembly groove, wherein the lower part of the rotating disk and the upper end of the ratchet are connected to a protruding assembly, and a mounting cap is also included, wherein the mounting cap mounts the rotating disk on the surface of the mounting post.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the wrist support is placed on the arm near the wrist, ensuring the back of the hand support is above the back of the hand. The tightening sleeve is located at the wrist. Two cloth straps are wrapped around the user's arm and secured with Velcro. When adjustment is needed, the rotating disc is turned, which drives the ratchet to rotate on the mounting post. During the rotation of the ratchet, the pull rope connected to it rotates, thus drawing more of the pull rope into the mounting groove. The shortened pull rope tightens the tightening sleeve, making it suitable for different user hand shapes. Finally, the pawl locks onto the ratchet surface to prevent the ratchet from reversing and releasing the pull rope. Attached Figure Description

[0017] Example 1, such as Figure 1-3As shown, the adjustable protective gear includes a wrist support frame 1, with a hand back support frame 3 rotatably mounted on one side of the wrist support frame 1. It also includes two cross-arranged pull ropes 5, with their ends connected to the wrist support frame 1 and the hand back support frame 3 respectively. A pad 9 is provided at the bottom of both the wrist support frame 1 and the hand back support frame 3, with a hole 10 on the side of the pad 9 near the hand back support frame 3. During use, a finger passes through the hole 10 and connects to the hand back support frame 3. A tightening sleeve 6 is fitted on the surface of the pull ropes 5, and the pull rope 5 connected to the wrist support frame 1 extends into the interior of the wrist support frame 1. It also includes an adjustment component 7, which can adjust the length of the pull ropes 5. A mounting groove 2 is provided on one side of the wrist support frame 1, and a connecting block 4 is fixedly connected to one side of the hand back support frame 3. The connecting block 4 is rotatably mounted in the mounting groove 2. A sponge pad is provided at the contact area between the wrist support frame 1 and the user. The support frame 3 and the user contact area are provided with a sponge pad. The wrist support frame 1 has cloth straps installed on both sides near the port. The free ends of the two cloth straps are provided with corresponding Velcro. The adjustment component 7 includes a mounting groove 71 opened at the upper end of the wrist support frame 1. The mounting groove 71 is fixedly mounted with a mounting post 72. It also includes a ratchet 73. The ratchet 73 rotates inside the mounting groove 71 with the help of the mounting post 72. A pawl 77 is slidably provided on the surface of the wrist support frame 1. The pawl 77 can slide into the mounting groove 71 and get stuck on the surface of the ratchet 73. One end of the pull rope 5 extends into the mounting groove 71 and tightens as the ratchet 73 rotates. A rotating disk 74 is provided at the port of the mounting groove 71. The lower part of the rotating disk 74 is connected to the upper end of the ratchet 73 with a protrusion 76. It also includes a mounting cap 75. The mounting cap 75 mounts the rotating disk 74 on the surface of the mounting post 72.

[0018] Working principle: When in use, place the wrist support 1 on the arm near the wrist, ensuring that the back of the hand support 3 is above the back of the hand. At this time, the tightening sleeve 6 is located at the wrist. Wrap the two cloth straps around the user's arm and fix them with Velcro. When adjustment is needed, rotate the rotating disk 74. The rotating disk 74 drives the ratchet 73 to rotate on the mounting post 72. During the rotation of the ratchet 73, the pull rope 5 connected to it rotates with it, thereby pulling more of the pull rope 5 into the mounting groove 71. Thus, the tightening sleeve 6 is tightened by the shortened pull rope 5, which can adapt to different user hand sizes. Finally, the pawl 77 is locked on the surface of the ratchet 73 to prevent the ratchet 73 from reversing and releasing the pull rope 5.
