Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training auxiliary devices, and further relates to a universal locking device and a lower limb rehabilitation training device. Background Art

[0002] In lower limb stepping rehabilitation training equipment, in order to adapt to the different training positions of the patient's feet, the pedal device often needs to provide universal adjustment and locking functions. Existing mechanisms mostly use a clamping ball head structure. The ball head is clamped by a pair of splints in the longitudinal direction. The rear ends of the two splints are fixedly connected. The ball head is located in the middle of the two splints, and the locking knob is located at the front end of the two splints. By turning the locking knob at the front end of the two splints, the two splints are clamped together. However, this clamping ball head structure lacks pre-tightening, and the lever clamping force of this clamping ball head structure is unevenly distributed, which has the risk of loss of force after frequent use. At the same time, this structure uses the rigid deformation of the two splints to provide the required locking force for the extrusion force. In addition, the spacing between the two pedals using this structure is mostly fixed. The lower limb stepping rehabilitation training equipment cannot adjust the leg spacing according to patients with different knee widths, which reduces functional adaptability and comfort.

It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be considered as the scope of protection of the present utility model.

[0042] refer to Figure 1 and Figure 2 The utility model provides a universal locking device 1, including a base 11, a splint 12 and a ball head 13. A first ball socket 111 and a plurality of first locking holes 112 are provided on one side of the base 11; the splint 12 is arranged at intervals on one side of the base 11, and a second ball socket 121 matching the first ball socket 111 and a second locking hole 122 matching the first locking hole 112 are provided on the splint 12, and a plurality of second locking holes 122 are arranged at the four corners of the splint 12, and the first locking hole 112 and the second locking hole 122 are suitable for being locked and connected by a first locking member; one end of the ball head 13 is movably arranged in the first ball socket 111 and the second ball socket 121, and the damping of the ball head 13 is adjusted by the locking force of the first locking member.

[0043] In this embodiment, the clamping plate 12 and the base 11 clamp the ball head 13 front and back, and the first locking members located at the four corners of the clamping plate 12 are used to adjust the clamping force of the clamping plate 12 to ensure that the ball head 13 has a suitable and uniform clamping force, which is safe, labor-saving and more adaptable.

[0044] Specifically, the clamping plate 12 and the base 11 are spaced apart. A first locking member is fixedly connected to the first locking hole 112 and the second locking hole 122, and clamps the ball head 13 between the first ball socket 111 and the second ball socket 121. One end of the ball head 13 is movably disposed between the first ball socket 111 and the second ball socket 121, and the other end is fixedly connected to the pedal 21. The pedal 21 is universally movable and locked through the ball head 13, the clamping plate 12, and the base 11. By adjusting the locking force of the first locking member, the spacing between the clamping plate 12 and the base 11 can be adjusted, thereby adjusting the damping of the ball head 13, so that the ball head 13 is universally rotatable between the first ball socket 111 and the second ball socket 121. The second locking holes 122 are located at the four corners of the splint 12, and the first locking piece locks the four corners of the splint 12 and the base 11, so that the clamping force of the splint 12 and the base 11 on the ball head 13 is more uniform, and the connection method between the splint 12 and the base 11 can also play a partial pre-tightening role, to avoid the ball head 13 from being separated from the first ball socket 111 and the second ball socket 121 when the damping of the ball head 13 is reduced, and the safety of the ball head 13 is better.

[0045] Furthermore, it also includes a driving member 14 and a bracket 15. The bracket 15 is arranged on one side of the splint 12. The bracket 15 is provided with a first clamping hole 151. The driving member 14 is arranged in the first clamping hole 151. After rotating the driving member 14, the driving member 14 is suitable for driving the splint 12 close to the base 11 and clamping the ball head 13.

[0046] In this embodiment, there is a certain distance between the base 11 and the splint 12, so that the ball head 13 is suitable for rotating between the base 11 and the splint 12 and has damping, thereby realizing universal adjustment and pre-tightening of the ball head 13. The driving member 14 is suitable for driving the splint 12 close to the base 11, and the ball head 13 is realized by the driving member 14 to rotate and stop immediately. The bracket 15 can also strengthen the connection strength between the base 11 and the splint 12 to prevent the pedal 21 from falling suddenly after being unlocked, thereby ensuring safety.

[0047] Specifically, the clamping plate 12 and base 11 are locked and spaced relative to each other by a first locking member, allowing the clamping plate 12 and base 11 to universally adjust and preload the ball head 13. The driver 14 then presses the clamping plate 12 toward the side closest to the base 11, reducing the distance between the clamping plate 12 and base 11 and clamping the ball head 13 therebetween with greater force, thereby increasing the damping of the ball head 13. Reversing the driver 14, moving it away from the clamping plate 12, increases the distance between the clamping plate 12 and base 11, reduces the damping of the ball head 13, and provides the ball head 13 with greater degrees of freedom. In other words, in this embodiment, the clamping plate 12 and base 11 act as a preload. Regardless of how the driver 14 is used, the ball head 13 will not be at risk of disengaging from the first and second ball sockets 111, 121, thereby preventing the pedal 21 from suddenly falling after unlocking and ensuring safety. The bracket 15 wraps around the splint 12 and is fixedly connected to the base 11, thereby enhancing the connection strength between the splint 12 and the base 11, preventing the splint 12 from accidentally detaching from the base 11, and reducing the risk of the ball head detaching. The splint 12 is controlled by the driving member to move closer to or away from the base 11, with a simple structure and low cost.

[0048] It is worth noting that the drive member 14 is an adjustable locking handle. The adjustable locking handle is secured to the bracket 15 via a threaded connection or clamping mechanism. By rotating the adjustable locking handle, friction is generated between the bracket 15 and the clamping plate 12, thereby adjusting and locking the position or angle of the clamping plate 12. The drive member 14 includes, but is not limited to, an adjustable locking drive member 14. A screw, telescopic rod, or the like may also be used, as long as it can drive the clamping plate 12 toward the side closer to the base 11. The drive member 14 can be driven manually or by a motor, both of which are variations of the present application.

[0049] Preferably, a mounting groove 152 is provided on the side of the bracket 15 close to the base 11, and the splint 12 is disposed in the mounting groove 152. A plurality of third locking holes 113 are further provided on one side of the base 11. The third locking holes 113 are disposed at the four corners of the base 11 and are relatively located outside the first locking holes 112. The bracket 15 is provided with fourth locking holes 153 that match the third locking holes 113. The fourth locking holes 153 are disposed at the four corners of the bracket 15. The fourth locking holes 153 and the third locking holes 113 are locked and connected by a second locking member. The bracket 15 is disposed on one side of the base 11 via the second locking member, and the splint 12 is relatively located inside the bracket 15 to prevent the splint 12 from being dislocated or falling. The bracket 15 wraps around the splint 12 and secures the splint 12 to the side of the base 11, further increasing the safety of the splint 12 and preventing it from falling.

[0050] Furthermore, the first pressing hole 151 is provided at the center of a side of the bracket 15 away from the base 11 and is relatively located at the center of the ball head 13 .

[0051] In this embodiment, the driving member 14 is directly opposite to the center of the ball head 13 and presses the clamping plate 12 to lock the position of the ball head 13. The locking force of the ball head 13 is more uniform and direct, and the safety is higher.

[0052] Specifically, a third locking hole 113 is provided on the side of the bracket 15 away from the base 11. The third locking hole 113 is relatively located at the center of the side of the bracket 15 away from the base 11, and is relatively located at the center of the splint 12 and the center of the ball head 13. When the driving member 14 squeezes the splint 12, the pressure of the splint 12 on the ball head 13 is more uniform. Preferably, a fixing groove 123 is also provided on the side of the splint 12 away from the base 11. A wear-resistant sheet 124 is provided in the fixing groove 123. The driving member 14 is suitable for abutting and pressing the wear-resistant sheet 124. In this embodiment, the wear-resistant sheet 124 increases the wear resistance of one side of the splint 12, thereby preventing the side wall of the splint 12 from being worn. Moreover, the wear-resistant sheet 124 can be detachably installed in the fixing groove 123 of the splint 12. The wear-resistant sheet 124 can be replaced to improve the durability and service life of the splint 12 and reduce costs.
