[0029] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0030] As Figure 1 shown, a technical solution is proposed in the first aspect of the present utility model. A four-way adjustable hand activity instrument mounting bracket mainly includes a base 10, a hand support member, a spherical connection member, and a connection member 30; the hand support member is intended to connect the hand activity instrument, the connection member 30 is provided at the bottom of the hand support member, the spherical connection member is rotatably connected to the base 10, so that the hand support member can achieve activities within a certain angular range, and the quick-release design between the connection member 30 and the spherical connection member is conducive to the user conveniently disassembling the hand support member.

[0031] As Figure 1 and Figure 2As shown, the hand support component includes an upper part 22 of the hand support and a lower part 21 of the hand support. The lower part 21 of the hand support and the upper part 22 of the hand support are detachably connected. When the lower part 21 of the hand support and the upper part 22 of the hand support are disassembled, the hand activity instrument can be assembled onto the lower part 21 of the hand support. Connecting the upper part 22 of the hand support to the lower part 21 of the hand support can complete the installation and fixation of the hand activity instrument. After fixation, as Figure 8 shown.

[0032] As Figure 2 and Figure 3 shown, further, the base 10 includes a main body 11 and a bottom cover 12. The bottom cover 12 can be mutually covered with the main body 11, and a spherical cavity 11a is formed between the main body 11 and the bottom cover 12.

[0033] The main body 11 and the bottom cover 12 are two mutually detachable parts. The main body 11 is configured as a quasi-rectangular plate or block. A cavity is provided at the bottom of the main body 11, and the diameter of the cavity decreases upward to form a limiting hole. When the bottom cover 12 and the main body 11 are assembled together, a spherical cavity 11a that can accommodate the spherical structure in the spherical connection component is formed.

[0034] As Figure 2 and Figure 3 shown, further, the spherical connection component includes a first connection structure 41 and a second connection structure 42 that are connected to each other. The first connection structure 41 is configured as a sphere, and the second connection structure 42 is configured as a column. The first connection structure 41 is connected into the spherical cavity 11a, and the second connection structure 42 extends above the main body 11.

[0035] Among them, the first connection structure 41 and the second connection structure 42 are designed to be detachable. Specifically, a threaded groove is provided on the surface of the spherical structure, and a threaded post is provided at one end of the columnar structure. The threaded post is spirally installed into the threaded groove to form a ball-stick structure. Among them, the spherical structure is installed in the spherical cavity 11a, and the columnar structure is connected to the connection component 30.

[0036] Among them, the first connection structure 41 can rotate in the spherical cavity 11a, enabling the hand support component to tilt in four directions: left, right, front, and back. And the main body 11 forms a limiting hole around the second connection structure 42 to restrict the tilting angle of the second connection structure 42 relative to the main body 11.

[0037] In an alternative embodiment, the tilting range of the second connection structure 42 is ±10° in the front-back direction and ±14° in the left-right direction.

[0038] Among them, the tilting angle range of the columnar structure is jointly restricted by the limiting hole and the diameter of the columnar structure. When the aperture of the limiting hole is larger and the diameter of the columnar structure is smaller, the tilting range is larger. When the diameter of the columnar structure is smaller and the diameter of the columnar structure is larger, the tilting range is smaller.

[0039] It should be understood that free rotation is achieved through the spherical structure and the spherical cavity 11a. The resistance during rotation depends on the contact friction between the spherical structure and the spherical cavity 11a. To increase the damping force during rotation, preferably, a first damping structure layer is provided inside the spherical cavity 11a, and a second damping structure layer is provided on the outer wall of the first connecting structure 41. The first damping structure layer and the second damping structure layer are in contact with each other to provide a damping force when the first connecting structure 41 rotates relative to the spherical cavity.

[0040] Optionally, the damping structure layer can adopt wear-resistant elastic layers such as rubber structure layers, nylon structure layers or silicone structure layers.

[0041] As Figure 3 and Figure 7 shown, the first damping structure layer includes an upper outer rubber shell part 413 and a lower outer rubber shell part 414, and the second damping structure layer includes an upper inner rubber shell part 411 and a lower inner rubber shell part 412. The upper inner rubber shell part 411 and the lower inner rubber shell part 412 are fixed to the outer wall of the first connecting structure 41, and the upper outer rubber shell part 413 and the lower outer rubber shell part 414 are fixed to the inner wall of the spherical cavity 11a.

[0042] Among them, the upper outer rubber shell part 413 is bonded to the inner wall of the main body 11, and the lower outer rubber shell part 414 is bonded to the inner wall of the bottom cover 12. After the bottom cover 12 is installed on the main body 11, the upper outer rubber shell part 413 and the lower outer rubber shell part 414 are joined to form a spherical shape and wrap around the outer wall of the upper inner rubber shell part 411 and the lower inner rubber shell part 412. At this time, the inner surfaces of the upper outer rubber shell part 413 and the lower outer rubber shell part 414 are in contact with the outer surfaces of the upper inner rubber shell part 411 and the lower inner rubber shell part 412, and provide damping when rotating relative to each other.

[0043] In this way, this damping effect has a certain limiting effect on the movement of the handrest component, preventing the handrest component from being easily shaken during use.

[0044] As Figure 6 shown, further, a positioning slot 11b is provided at the bottom of the main body 11, and a protrusion is provided at the outer edge of the bottom cover 12. When the bottom cover 12 is closed with the main body 11, the protrusion is snapped into the positioning slot 11b, and then the bottom cover 12 is rotated to make the protrusion deviate from the positioning slot 11b. At this time, the bottom cover 12 and the main body 11 are locked in the thickness direction to form a limit and cannot be separated. Therefore, it can ensure that the spherical cavity 11a presses the first connecting structure 41.

[0045] In this way, after the bottom cover 12 is closed, the stability of the mutual fixation can be ensured, preventing the bottom cover 12 from falling off, and enabling the spherical cavity 11a to always maintain a pressing force on the first connecting structure 41.

[0046] Preferably, a rubber pad 13 is provided at the bottom of the main body 11. After the bottom cover 12 is engaged with the main body 11, the bottom of the bottom cover 12 is above the lower end surface of the rubber pad 13.

[0047] Furthermore, the connecting member 30 is connected to the bottom of the handrest member, and the connecting member 30 is detachably connected to the second connecting structure 42.

[0048] In this way, it is beneficial for the user to separate the handrest member and the base 10 from each other.

[0049] As Figure 4 shown, in an alternative embodiment, a first engaging structure 421 is provided at a predetermined height on the outer wall of the second connecting structure 42. The connecting member 30 is provided with a jack. The second connecting structure 42 can be inserted into the jack, and a second engaging structure is provided in the jack. The first engaging structure 421 and the second engaging structure are engaged with each other.

[0050] In an alternative embodiment, the second connecting structure 42 and the jack are inserted in a first direction, and the first engaging structure 421 and the second engaging structure are engaged and connected in a second direction. The first direction and the second direction are perpendicular.

[0051] Among them, the first engaging structure 421 and the second engaging structure adopt a way of engaging with a concave structure and a convex structure.

[0052] Taking the first engaging structure 421 as a tapered hole as an example.

[0053] Furthermore, the connecting member 30 includes a button 31, a clamping member 32 and a spring 33 which are linearly distributed. The clamping member 32 is arranged to be pressed to a first position by the button 31 and rebound to a second position by the spring 33. When the clamping member 32 is in the second position, the clamping member 32 can engage with the first engaging structure 421 in the jack. When the clamping member 32 is in the first position, the clamping member 32 is separated from the first engaging structure 421 in the jack.

[0054] Among them, a tapered protrusion is provided on one side of the clamping member 32 facing the first engaging structure 421. When the clamping member 32 is in the first position, the tapered protrusion is not in the jack, and the second connecting structure 42 can be freely inserted and removed in the jack. When the clamping member 32 is in the second position, the tapered protrusion can engage with the tapered hole inserted into the jack, so that the second connecting structure 42 cannot be pulled out.

[0055] In a specific embodiment, the connecting component 30 includes an upper half housing 30a and a lower half housing 30b. After the upper half housing 30a and the lower half housing 30b are assembled in an opposing manner, a cavity is formed inside. The clamping member 32 and the spring 33 are inside the cavity and can slide relative to the housing. Part of the button 31 is exposed outside the cavity and part is inside the cavity. When the button 31 is pressed, the clamping member 32 is in the first position. When the button 31 is released, the clamping member 32 is rebounded by the spring 33 and is in the second position.

[0056] In this way, users can conveniently disassemble and install the handrest component.

[0057] Combined with the above embodiments, the present utility model realizes that the handrest component can be adjusted in angle in four directions of left, right, front and back within a small range through the connection between the spherical structure and the base. Users can finely adjust the angle of the hand activity instrument. Especially during the rehabilitation training process, through this small range of angle adjustment, the hand can be in a comfortable angle. In addition, the handrest component can be quickly detached from the spherical connection component, so as to reduce the difficulty for users or rehabilitation therapists to install the hand activity instrument on the bracket and improve the user experience.

[0058] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to what is defined by the claims.
