Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a hand activity instrument bracket device. Background Art
[0002] Currently, hand rehabilitation training for patients with upper limb motor loss typically involves massage or acupuncture to stimulate the patient's hands, or using assistive devices to pull the patient's fingers to assist in hand movement, thereby stimulating the nervous system and muscles to restore motor function. However, massage and acupuncture require specialized therapists, resulting in high labor costs. To reduce the workload of rehabilitation therapists, improve rehabilitation efficiency, and lower patient costs, there is an urgent need to introduce more advanced technologies into the rehabilitation field.
[0003] The application of rehabilitation therapy equipment in rehabilitation medicine solves the above problems. However, when existing auxiliary equipment is used for hand rehabilitation, the patient's arm is usually placed on the table. For patients with weak arms, their upper limb posture cannot be fixed comfortably, and the experience of the entire rehabilitation process is poor. Patent document 1 discloses a technical solution that can adjust the position of the hand activity instrument through three brackets, but the brackets cannot adjust the angle of the hand bones, which still does not meet the user's usage needs.

[0028] In order to better understand the technical content of the present invention, specific embodiments are given and described below in conjunction with the accompanying drawings.
[0029] like Figure 1 As shown, the hand activity instrument support device 100 shown in the present invention is used to limit the hand activity instrument 200. The user's affected limb can be placed on the hand activity instrument 200 and supported by the hand activity instrument support device 100 to complete rehabilitation training. Among them, the hand activity instrument support device 100 is intended to provide users with more optional support angles to enable users to have a better user experience.
[0030] Combine Figure 2As shown, the first aspect of the present invention provides a hand activity instrument support device, comprising a mounting base 10, a hand support structure 20 and a limiting component. The hand support structure 20 comprises a lower half 21 and an upper half 22, and the lower half 21 and the upper half 22 are detachably connected.
[0031] It can be understood that the lower part 21 mainly supports and connects the mounting base 10 , and the upper part 22 mainly limits the hand activity instrument 200 .
[0032] Furthermore, the mounting base 10 is provided with a limiting groove 11 along the first direction, such as Figure 2 As shown, the first direction is the length direction of the lower part 21, which is also the length direction of the hand activity instrument 200, that is, the extension direction of the user's palm. In this direction, the user's hand can change the angle relative to the forearm to adjust to a suitable angle.
[0033] In an optional embodiment, if Figure 2 As shown, the hand support structure 20 is arranged in the limiting groove 11 and can rotate relative to the mounting base 10 in a second direction perpendicular to the first direction, so that the hand support structure 20 can switch its position relative to the mounting base 10 between the first position, the second position or the third position.
[0034] Furthermore, the hand activity device installed on the hand support structure 20 is arranged along the first direction. When the hand support structure 20 is in the second position, the hand activity device maintains a horizontal posture. When the hand support structure 20 is in the first position, the hand activity device tilts forward. When the hand support structure 20 is in the third position, the hand activity device tilts backward.
[0035] In this way, the palm rest structure 20 can be adjusted to a horizontal position, a forward tilted position, or a backward tilted position to meet the user's adjustment needs.
[0036] Furthermore, the limiting component is configured to maintain the hand support structure 20 in the first position, the second position, or the third position. In this way, after the angle of the hand support structure 20 is adjusted, the limiting component can maintain the hand support structure 20 in this position to ensure the stability of the support.
[0037] Combine Figure 3 As shown, a shaft sleeve structure 211 is provided below the hand support structure 20 , a rotating shaft 121 is provided in the limiting groove 11 , and the shaft sleeve structure 211 is connected to the rotating shaft 121 so that the hand support structure 20 is driven around the axis of the rotating shaft 121 .
[0038] Specifically, the lower part 21 is constructed to have a planar structure, and a sleeve structure 211 is arranged below the planar structure. A sleeve body 12 for accommodating the rotating shaft 121 is provided in the limiting groove 11, so that the rotating shaft 121 is fixed relative to the limiting groove 11. The sleeve structure 211 is sleeved on the outer wall of the rotating shaft 121, so that the sleeve structure 211 and the rotating shaft 121 can rotate freely relative to each other, thereby changing the angle of the hand support structure 20.
[0039] Furthermore, a torsion spring 122 is provided on the surface of the rotating shaft 121 , and both ends of the torsion spring 122 are respectively connected to the rotating shaft 121 and the shaft sleeve structure 211 . The torsion spring 122 is configured to keep the palm support structure 20 restored to the second position.
[0040] In this way, through the design of the torsion spring 122, the hand support structure 20 can be kept stable near the second position, which is beneficial for the hand support structure 20 to be in a stable state when it is in a non-fixed position (first, second or third position), especially when installing the hand activity instrument 200 and the lower half 21 and upper half 22 of the hand support structure 20.
[0041] In an optional embodiment, the limiting component includes at least one positioning shaft 40, a first positioning hole 13 is provided on the mounting seat 10, and a second positioning hole is provided on the sleeve structure 211. When the hand support structure 20 is in the second position, the first positioning hole 13 and the second positioning hole are aligned, and the positioning shaft 40 can be inserted into the first positioning hole 13 and the second positioning hole to keep the hand support structure 20 in the second position.
[0042] Among them, such as Figure 3 As shown, the positioning shaft 40 can be set as a pair, respectively located on the left and right sides of the mounting base 10. When the hand support structure 20 is in the second position, after the first positioning hole 13 and the second positioning hole are aligned, the positioning shaft 40 is inserted into the second positioning hole along the first positioning hole 13. The relative positions of the hand support structure 20 and the mounting base 10 are locked, so that the hand support structure 20 remains in the second position.
[0043] Combine Figure 2 and Figure 4 As shown, the upper end face of the mounting base 10 is provided with a first end face and a second end face, and the first end face and the second end face form a relative angle. When the lower end face of the hand support structure 20 is in contact with the first end face, the hand support structure 20 is in a first position, and when the lower end face of the hand support structure 20 is in contact with the second end face, the hand support structure 20 is in a third position.
[0044] like Figure 4-6 As shown, the inner wall of the limiting groove 11 is provided with two pairs of third limiting holes 14 , the limiting component includes a limiting structure 30 , and the limiting structure 30 includes a pair of retractable limiting rods 35 , which can extend into the third limiting holes 14 .
[0045] Since the limiting of the first position and the third position is similar to that of the second position, both are achieved through the cooperation of the shaft and the hole. Therefore, when the hand support structure 20 tilts forward to be aligned with the first end face, it is in a cross-stable state, which is convenient for fixing it to the first position through the limiting structure 30. When the hand support structure 20 tilts backward to be aligned with the second end face, it is in a cross-stable state, which is convenient for fixing it to the third position through the limiting structure 30.
[0046] Furthermore, when the palm rest structure 20 is in the first position or the third position, the axis of the limiting rod 35 and the axis of the third limiting hole 14 coincide with each other.
[0047] In an alternative embodiment, in combination with Figure 5-6 As shown, the limiting structure 30 also includes an extension button 31 and a retraction button 34. The limiting rod 35 is configured to be controlled by the extension button 31 or the retraction button 34 to move to the extension position and the retraction position. The extension button 31 is provided with a pair of wedge surfaces. When the extension button 31 is pressed, the limiting rod 35 slides on the surface of the wedge surface and moves from the retraction position to the extension position. The bottom of the extension button 31 is also provided with a spring piece 32, which contacts the retraction button 34. The spring piece 32 is configured to drive the extension button 31 to reset after the retraction button 34 is pressed.
[0048] Furthermore, the limiting rod 35 and the hand support structure 20 are elastically connected via a spring 33 , so that the limiting rod 35 has a tendency to move from the extended position to the retracted position.
[0049] In this way, when it is necessary to limit the position, press the extension button 31. When the extension button 31 is pressed, the limit rod 35 slides on the surface of the wedge surface and moves from the retracted position to the extended position, that is, the limit rod 35 extends into the third limit hole 14 to achieve the limitation of the position. When it is necessary to release the limitation, press the retraction button 34. When the retraction button 34 is pressed, it compresses the spring piece 32. After the spring piece 32 is deformed by pressure, it applies pressure to the extension button 31 in the reset direction to reset it. At the same time, the spring 33 applies elastic force to the limit rod 35, so that the limit rod 35 moves from the extended position to the retracted position, releasing the limitation at this position.
[0050] In combination with the above embodiments, the bracket device proposed in this application provides support for the palm rest structure and posture adjustment within a certain angle range, especially it can adjust the forward and backward posture, so that the user can choose between the horizontal position, forward position and backward position. The palm rest structure can be kept in a predetermined position through the limiting component to provide stable support to meet the user's usage needs.
[0051] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
