Abstract
Description
Technical Field
[0001] This application relates to the field of cervical spine joint repair, and more particularly to a rehabilitation training device with adjustable resistance. Background Technology
[0002] Chinese invention patent CN2024100607520 discloses an resistance training device that allows for adjustment of the resistance training angle of the cervical spine within a range of 0-120° by rotating between a fixed plate and a backrest.
[0003] However, in practical use, the aforementioned resistance training device has the following drawbacks: the two ends of the torsion spring are connected to the fixed plate and the backrest respectively. The larger the angle between the fixed plate and the backrest, the greater the resistance. This requires the patient to rotate their cervical spine at a greater angle to increase the resistance training intensity. However, if the patient's cervical spine rotates too much, it is extremely easy to suffer secondary injury, which defeats the purpose of resistance training rehabilitation. Utility Model Content
[0004] This invention provides an adjustable resistance rehabilitation training device, which has the advantage of adjustable resistance to suit different patients.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] An adjustable resistance rehabilitation training device includes a main shell, a backrest that fits against the patient's cervical spine, and a resistance adjustment device.
[0007] The resistance adjustment device includes a rotating paddle, a push block, a torsion spring, and a rotating column; the push block and the rotating paddle are connected and fixed, one end of the torsion spring is inserted and fixed to the backing plate, and the other end is located within the rotation range of the push block; the rotating column is set inside the torsion spring and is fixedly installed on the main housing, and the backing plate is rotatably connected to the main housing through the rotating column.
[0008] Preferably, there are two resistance adjustment devices; wherein the torsion springs have different torques.
[0009] Preferably, one of the torsion springs has a torque of 1-2 kg and the other has a torque of 2-4 kg.
[0010] Preferably, the main housing is provided with an arc-shaped rotating groove, the push block is located inside the main housing, the rotating paddle is located outside the main housing, and the connection between the push block and the rotating paddle slides along the arc-shaped rotating groove.
[0011] Preferably, the main housing is rotatably mounted with a high support bracket and a low support bracket on the side facing away from the abutment plate. There are two high support brackets and two low support brackets, which are respectively installed at both ends of the main housing.
[0012] Preferably, a back support plate is rotatably mounted on the side of the main housing facing away from the backing plate, and a high support bracket and a low support bracket are located between the back support plate and the main housing.
[0013] Preferably, the upper part of the backrest is provided with a groove, and a soft silicone layer is laid in the groove.
[0014] Compared with the prior art, the advantages or beneficial effects of the technical solution of this application include:
[0015] 1. By rotating the lever to control the push block and the torsion spring, the two ends of the torsion spring are pressed against the backing plate and the push block respectively. When the patient's cervical spine applies pressure to the backing plate, the elasticity of the torsion spring can generate resistance to the cervical spine. Repeatedly, this achieves the purpose of rehabilitation training.
[0016] 2. This rehabilitation training device fits snugly against the user's cervical spine, and when the cervical spine applies force to the support board, the elasticity of the torsion spring provides feedback resistance to the cervical spine. To accommodate patients with different degrees of cervical spondylosis, torsion springs with varying torque can be replaced, thus achieving resistance training with different levels of strength.

[0023] The following detailed description of the embodiments of this application, in conjunction with the accompanying drawings, will provide a thorough understanding of how this application uses technical means to solve technical problems and achieve corresponding technical effects, enabling its implementation. The embodiments of this application and the various features within them can be combined with each other without conflict, and all resulting technical solutions are within the protection scope of this application.
[0024] It should be clearly stated that the embodiments described below are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. Example
[0025] like Figure 1-5 As shown, an adjustable resistance rehabilitation training device includes a main shell 3, a backrest 1 that fits against the patient's cervical spine, and a resistance adjustment device.
[0026] The resistance adjustment device includes a rotating paddle 2, a push block 9, a torsion spring 8, and a rotating column. The push block 9 and the rotating paddle 2 are connected and fixed. One end of the torsion spring 8 is inserted and fixed to the support plate 1, and the other end is located within the rotation range of the push block 9. The rotating column is located inside the torsion spring 8 and is fixedly installed on the main housing 3. The support plate 1 is rotatably connected to the main housing 3 through the rotating column. There are two resistance adjustment devices; the torsion springs 8 have different torques. One torsion spring 8 has a torque of 1-2 kg, and the other torsion spring 8 has a torque of 2-4 kg. The main housing 3 is provided with an arc-shaped rotating groove 11. The push block 9 is located inside the main housing 3, and the rotating paddle 2 is located outside the main housing 3. The connection between the push block 9 and the rotating paddle 2 slides along the arc-shaped rotating groove 11.
[0027] The internal components and working principle of the resistance regulating device are as follows:
[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the resistance is adjusted through the following steps:
[0029] Because the torsion springs on the left and right sides have different torques, when the user turns the lever 2, causing the push block 9 fixed to it to rotate, the push block 9 on that side contacts the lower end of the torsion spring. Figure 4 At this point, the torsion spring on that side serves as the source of power for resistance training.
[0030] Similarly, when it is necessary to change the resistance, the push block 9 described above can be rotated in the opposite direction so that it does not contact the lower end of the torsion spring. At the same time, by rotating the push block 9 to the lower end of another torsion spring with a different torque, it is possible to switch to a torsion spring with a different torque to provide resistance, thus adapting to different patients.
[0031] The left or right push block can be used alone to provide resistance, or they can be used simultaneously. A total of 3 different levels of resistance are generated.
[0032] If the user needs greater resistance, the rotating lever 2 can be rotated at the same time so that the push block 9 is in contact with the end of the torsion spring, so that the torsion spring can provide greater resistance when subjected to force.
[0033] The three different resistance levels mentioned above can be selected by the patient according to their actual situation, and can be adapted to patients with different injury procedures.
[0034] like Figure 2 As shown, a high support bracket 5 and a low support bracket 4 are rotatably installed on the side of the main housing 3 facing away from the backing plate 1. There are two of each of the high support bracket 5 and the low support bracket 4, which are respectively installed at both ends of the main housing 3.
[0035] Both the high-support bracket 5 and the low-support bracket 4 are used in close contact with the wall. When the patient's training habits require them to be closer to the wall, the low-support bracket 4 can be flipped to bring the main shell 3 closer to the wall. Conversely, the high-support bracket 5 can be flipped to move the main shell 3 further away from the wall.
[0036] like Figure 1 As shown, a back support plate 6 is rotatably mounted on the side of the main housing 3 facing away from the backrest plate 1. A high support bracket 5 and a low support bracket 4 are located between the back support plate 6 and the main housing 3. The back support plate 6 fits snugly against the user's back, allowing for more effective force application when the cervical spine is in close contact with the backrest plate 1.
[0037] like Figure 5 As shown, when the back support plate 6 is folded up, it cooperates with the main shell 3 to form a closed structure, making the storage box easy to carry around.
[0038] In this embodiment, a groove 12 is provided above the backrest 1, and a soft silicone layer is laid inside the groove 12. The soft silicone layer comes into contact with the skin, increasing the user's comfort.
