Abstract
Description
Technical Field
[0001] This utility model relates to the field of elbow joint fixation braces, and more specifically, it relates to an elbow joint fixation brace with a stable support effect. Background Technology
[0002] An elbow brace is a medical device used to restrict elbow joint movement, provide stability and protection. It is usually made of a combination of rigid or semi-rigid materials (such as plastic, metal, carbon fiber, etc.) and soft padding, and is fixed to the arm by straps, Velcro or hinge structure.
[0003] Elbow joint fixation braces that provide stable support need to balance rigidity, fit, comfort, and functionality. They generally use aluminum alloy, carbon fiber, or polymer plastics (such as PVC) as the main structure to provide bending and torsional support. Some elbow joint fixation braces are equipped with adjustable metal hinges to allow control of the joint's range of motion (such as limiting flexion and extension angles) while maintaining stability. Existing elbow joint fixation braces generally extend to the forearm and upper arm, using multi-point fixation (such as Velcro, straps) to distribute pressure and avoid local compression or displacement.
[0004] Existing elbow joint fixation braces with stable support generally use universal braces (such as S / M / L sizes), which cannot adapt to special body types (such as obesity, muscularity, children or adolescents). When the brace is too tight, it can compress nerves and blood vessels, causing numbness, swelling or pressure sores. When the brace is too loose, it can cause the brace to slip or shift, lose its fixation function, and increase the risk of secondary injury. As a result, universal braces cannot adapt to individual differences, leading to poor flexibility, high health risks and poor customer experience.
[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes an elbow joint fixation brace with stable support effect. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an elbow joint fixation brace with stable support effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an elbow joint fixation brace with stable support effect, comprising a forearm fixation support and an upper arm fixation support;
[0008] The forearm fixing support and the upper arm fixing support are connected by two telescopic components with adjustable distances.
[0009] Both sides of the forearm fixing support and the upper arm fixing support are provided with clamping components to fix the forearm and upper arm of different users, and both sides of the forearm fixing support and the upper arm fixing support are provided with adjusting components to adjust the position of the clamping components.
[0010] The telescopic component is provided with a moving component for controlling the movement of the telescopic component, and one of the adjusting components is provided with a control component for controlling the movement of the moving component;
[0011] Each of the aforementioned adjustment and control components is provided with a limit component for fixing it.
[0012] Preferably, both telescopic components include support rods and connecting rods. One end of the upper arm fixing bracket is connected to two support rods, and one end of the lower arm fixing bracket is connected to two connecting rods. The ends of the two connecting rods away from the lower arm fixing bracket slide within the two support rods, which facilitates the adjustment of the distance between the lower arm fixing bracket and the upper arm fixing bracket.
[0013] Preferably, each clamping assembly includes a clamping plate, a protective pad, a support block, and a bearing sleeve. Clamping plates are slidably installed on both sides of the forearm fixing bracket and the upper arm fixing bracket. A protective pad is connected to one side of each clamping plate, and a support block is connected to the side of each clamping plate away from the protective pad. A bearing sleeve is connected to the side of each support block away from the clamping plate. Each support block can reciprocate on its respective forearm fixing bracket and upper arm fixing bracket, which facilitates clamping and fixing of the user's forearm and upper arm.
[0014] Preferably, each of the adjustment components includes a support arm, a screw, a baffle, and a handle. Support arms are connected to the corresponding sides of the forearm fixing bracket and the upper arm fixing bracket. A rotating shaft is rotatably connected to the position of the support block on each support arm. The end of each rotating shaft near the support block is rotatably connected to a nearby bearing sleeve. A baffle is installed at the end of each rotating shaft away from the support block. A handle is connected to each baffle to facilitate the control of the movement of the clamp.
[0015] Preferably, the moving assembly includes a stabilizing plate and a rack, wherein a stabilizing plate is connected to one side of one of the support rods, a rack is installed at the lower end of the stabilizing plate, and the stabilizing plate extends to the middle of the support arm on the forearm fixing bracket, facilitating the transmission of the support rod.
[0016] Preferably, the control component includes a rotating shaft, a handle, and a gear. The rotating shaft is rotatably connected through the support arm near the stabilizing plate on the forearm fixed support. A gear is connected to one end of the rotating shaft near the stabilizing plate. The gear meshes with a rack. A handle is connected to the other end of the rotating shaft away from the gear, which facilitates the control of the movement of the moving component.
[0017] Preferably, both limiting components include a limiting rod, a spring, and a limiting hole. A limiting rod is slidably connected through each baffle and a handle. Each limiting rod is connected to its corresponding baffle or handle by a spring. Each support arm has multiple circumferentially formed limiting holes corresponding to each baffle or handle. Each limiting rod can reciprocate within any one of the corresponding limiting holes, facilitating the limiting of each adjusting component and control component.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. In this utility model, multiple clamping components, adjusting components, and limiting components are set on the forearm fixing bracket and the upper arm fixing bracket. By gripping the limiting rod on one of the baffles and pulling it outwards, the limiting rod stretches the connected spring until it disengages from its limiting hole. Then, by gripping and rotating the handle, the baffle rotates, causing the screw to rotate. The screw then rotates on the support arm and moves back and forth. Simultaneously, the screw rotates within the bearing sleeve. When moving back and forth on the support arm, the bearing sleeve moves the clamps and protective pads on the clamps toward the user's arm. Then, other clamps are moved in sequence in the same way, and the user's forearm and upper arm are stably clamped by the corresponding clamps. Finally, the user releases the holding limit rod, and the spring rebounds to re-insert the limit rod into the corresponding limit hole, thereby fixing the screw. This solves the problem in the background technology that general-purpose braces cannot adapt to individual differences, resulting in poor flexibility, high health risks, and poor user experience.
[0020] 2. In this utility model, a movable component mounted on the telescopic assembly, a control component mounted on one of the support plates, and a limiting component mounted on the control component are used to place the user's forearm and upper arm in the forearm fixing bracket and upper arm fixing bracket, respectively. Then, by rotating one set of control components, the user first grasps the limiting rod on the handle and pulls it outward. Pulling the limiting rod stretches the connected spring until the limiting rod disengages from its limiting groove. Then, the user grasps the handle and rotates it. When the handle rotates, it causes the shaft to rotate, which in turn causes the gear to rotate. The mechanism causes the meshing racks to move, which in turn moves the stabilizing plate. This movement, in turn, moves the connected support rods on the connecting rods. When the two support rods move on their respective connecting rods, they move the connected upper arm support until the upper arm support is in the correct position. Then, the limiting rod is released, and the spring, through its rebound, re-inserts the limiting rod into the corresponding limiting hole. This fixes the distance between the forearm support and the upper arm support, effectively and precisely matching the arm length requirements of different users while ensuring the support position is highly compatible with the biomechanical characteristics of the human skeleton.

[0028] like Figure 1-5 As shown, this utility model provides an elbow joint fixation brace with a stable support effect, including a forearm fixation support 1 and an upper arm fixation support 2, which are used to support the user's forearm and upper arm.
[0029] The forearm fixing support 1 and the upper arm fixing support 2 are connected by two telescopic components 3 with adjustable distances. These components are used to allow the support rod 301 to slide on the connecting rod 302, thereby controlling the distance between the forearm fixing support 1 and the upper arm fixing support 2. They also serve to connect the forearm fixing support 1 and the upper arm fixing support 2.
[0030] Both telescopic components 3 include support rods 301 and connecting rods 302. One end of the upper arm fixed support 2 is connected to two support rods 301, and one end of the lower arm fixed support 1 is connected to two connecting rods 302. The ends of the two connecting rods 302 away from the lower arm fixed support 1 slide within the two support rods 301 respectively.
[0031] Both sides of the forearm fixing support 1 and the upper arm fixing support 2 are equipped with clamping components 4 for fixing the forearm and upper arm of different users. Both sides of the forearm fixing support 1 and the upper arm fixing support 2 are also equipped with adjusting components 5 for adjusting the position of the clamping components 4. These adjusting components 5 are used to grasp the limiting rod 801 on one of the baffles 503 and pull the limiting rod 801 outwards. When the limiting rod 801 is pulled, it stretches the connected spring 802 until the limiting rod 801 is pulled out of its limiting hole 803. Then, the grip 504 is grasped and rotated. The rotation of the grip 504 will cause the baffle 503 to rotate, which in turn will cause the screw 502 to rotate. At this time, the screw 502 will support the arm... The screw 502 rotates and moves back and forth on the support arm 501, while the screw 502 rotates within the bearing sleeve 404. When the screw 502 moves back and forth on the support arm 501, it moves the clamping plate 401 and the protective pad 402 on the clamping plate 401 towards the user's arm through the bearing sleeve 404. Then, other clamping plates 401 are moved in sequence in the same way, and the user's forearm and upper arm are stably clamped by the corresponding clamping plates 401. Finally, the holding limit rod 801 is released. At this time, the spring 802 will re-insert the limit rod 801 into the corresponding limit hole 803 through its elasticity, thereby fixing the screw 502. This can effectively adapt to the size of different users' upper arm and forearm, thereby improving the flexibility of use.
[0032] Each clamping assembly 4 includes a clamping plate 401, a protective pad 402, a support block 403, and a bearing sleeve 404. The clamping plates 401 are slidably installed on the corresponding sides of the forearm fixing support 1 and the upper arm fixing support 2, which are used to clamp and stabilize the user's forearm or upper arm. One side of each clamping plate 401 is connected to a protective pad 402, which is used to protect the user's forearm or upper arm. The side of each clamping plate 401 away from the protective pad 402 is connected to a support block 403, which is used to transmit power to the clamping plate 401. The side of each support block 403 away from the clamping plate 401 is connected to a bearing sleeve 404, which is used to allow the screw 502 to rotate within the bearing sleeve 404 without rotating the support block 403. Each support block 403 can reciprocate on its respective forearm fixing support 1 and upper arm fixing support 2.
[0033] Each adjustment component 5 includes a support arm 501, a screw 502, a baffle 503, and a handle 504. Support arms 501 are connected to the corresponding sides of the forearm fixing support 1 and the upper arm fixing support 2. A rotating shaft 701 is rotatably connected to the position of the support block 403 on each support arm 501, which is used to control the movement of the clamping plate 401. The end of each rotating shaft 701 near the support block 403 is rotatably connected to the adjacent bearing sleeve 404, and a baffle 503 is installed on the end of each rotating shaft 701 away from the support block 403, which is used to prevent the screw 502 from entering the entire interior of the support arm 501. A handle 504 is connected to each baffle 503, which is used to facilitate the user's handhold.
[0034] The telescopic assembly 3 is equipped with a moving component 6 for controlling its movement. One of the adjusting components 5 is equipped with a control component 7 for controlling the movement of the moving component 6. This control component 7 is used to place the user's forearm and upper arm in the forearm support 1 and upper arm support 2 respectively. Then, by rotating one set of control components 7, the user first grasps the limiting rod 801 on the handle 702 and pulls it outward. Pulling the limiting rod 801 stretches the connected spring 802 until the limiting rod 801 disengages from its limiting groove. Then, the user grasps the handle 702 and rotates it. When the handle 702 rotates, it drives the rotating shaft 701 to rotate. When the rotating shaft 701 rotates, it drives the gear 703 to rotate. When rotated, the meshing racks 602 move. The movement of the racks 602 moves the stabilizing plate 601. The movement of the stabilizing plate 601 moves the connected support rods 301 on the connecting rods 302. When the two support rods 301 move on their respective connecting rods 302, they move the connected upper arm fixing bracket 2 until the upper arm fixing bracket 2 is moved to the appropriate position. Then the limiting rod 801 is released. At this time, the spring 802 will re-insert the limiting rod 801 into the corresponding limiting hole 803 through its elasticity. This fixes the distance between the forearm fixing bracket 1 and the upper arm fixing bracket 2, which can effectively and accurately match the needs of different users' arm lengths, while ensuring that the position of the fixing bracket is highly adapted to the biomechanical characteristics of the human skeleton.
[0035] The moving assembly 6 includes a stabilizing plate 601 and a rack 602. One side of a support rod 301 is connected to the stabilizing plate 601, and the rack 602 is installed at the lower end of the stabilizing plate 601. The stabilizing plate 601 extends to the middle of the forearm fixing support 1 and the support arm 501 on the forearm fixing support 1. It is used to enable the meshing rack 602 to move by rotating the gear 703, thereby moving the stabilizing plate 601.
[0036] The control component 7 includes a rotating shaft 701, a handle 702, and a gear 703. The rotating shaft 701 is rotatably connected through the support arm 501 on the forearm fixed support 1 near the stabilizing plate 601. It is used to control the rotation of the gear 703. The end of the rotating shaft 701 near the stabilizing plate 601 is connected to the gear 703, which is used to control the movement of the rack 602. The gear 703 and the rack 602 mesh with each other. The end of the rotating shaft 701 away from the gear 703 is connected to the handle 702, which is used to facilitate the user's handhold.
[0037] Each adjustment component 5 and control component 7 is provided with a limiting component 8 for fixing it. The limiting component 8 is used to achieve the limiting of each adjustment component 5 and control component 7 by inserting the limiting rod 801 into the corresponding limiting hole 803 and then fixing the limiting rod 801 by the spring 802.
[0038] Both limiting components 8 include a limiting rod 801, a spring 802, and a limiting hole 803. A limiting rod 801 is slidably connected through each baffle 503 and a handle 702. The limiting rod 801 is used to insert into the corresponding limiting groove to achieve a fixing function. Each limiting rod 801 is connected to the corresponding baffle 503 or handle 702 by a spring 802, which is used to make the limiting rod 801 elastic and fix the limiting rod 801 inserted into the limiting hole 803. Each support arm 501 has multiple circumferentially formed limiting holes 803 corresponding to each baffle 503 or handle 702 to facilitate the insertion of the limiting rod 801. Each limiting rod 801 can slide back and forth in any corresponding limiting hole 803.
[0039] Working principle: When it is necessary to fix the user's elbow joint, first place the user's forearm and upper arm in the forearm fixing bracket 1 and upper arm fixing bracket 2 respectively. Then, by rotating one of the control components 7, first grasp the limiting rod 801 on the handle 702 and pull the limiting rod 801 outward. When pulling the limiting rod 801, the connected spring 802 is stretched until the limiting rod 801 is disengaged from its limiting groove. Then grasp the handle 702 and rotate the handle 702. When the handle 702 rotates, it will drive the rotating shaft 701 to rotate. When the rotating shaft 701 rotates, it will drive the gear 703 to rotate. When 703 rotates, the meshing rack 602 moves. The movement of rack 602 moves stabilizer 601. The movement of stabilizer 601 moves support rod 301 on connecting rod 302. When the two support rods 301 move on their respective connecting rods 302, they move the connected upper arm fixing bracket 2 until the upper arm fixing bracket 2 is moved to the appropriate position. Then the limiting rod 801 is released. At this time, spring 802 will rebound to re-insert the limiting rod 801 into the corresponding limiting hole 803, thereby fixing the distance between the forearm fixing bracket 1 and the upper arm fixing bracket 2.
[0040] Next, grasp the limiting rod 801 on one of the baffles 503 and pull it outward. When the limiting rod 801 is pulled, it will stretch the connected spring 802 until the limiting rod 801 is stretched out of the limiting hole 803. Then, grasp and rotate the handle 504. The rotation of the handle 504 will cause the baffle 503 to rotate, and the rotation of the baffle 503 will cause the screw 502 to rotate. At this time, the screw 502 will rotate on the support arm 501 and move back and forth. At the same time, the screw 502 will be in the bearing sleeve. When the screw 502 rotates within 404 and moves back and forth on the support arm 501, it will move the clamp 401 and the protective pad 402 on the clamp 401 toward the user's arm through the bearing sleeve 404. Then, the other clamps 401 are moved in sequence in the same way, and the user's forearm and upper arm are stably clamped by the corresponding clamps 401. Finally, the holding limit rod 801 is released. At this time, the spring 802 will re-insert the limit rod 801 into the corresponding limit hole 803 through its elasticity, thereby fixing the screw 502.
