Description

Technical Field

[0001] This utility model relates to the field of arm rehabilitation, and in particular to an arm rehabilitation exercise device. Background Technology

[0002] An existing patent (publication number: CN212817904U) discloses an arm rehabilitation exercise device. It includes a chair panel, with a backrest fixedly connected to one side of the top outer wall of the chair panel. First fixing buckles are fixedly connected to the outer walls of the opposite sides of the backrest near the middle. Two second fixing buckles are fixedly connected to the outer wall of one side of the backrest near the bottom. A tension band is inserted into the inner walls of the first and second fixing buckles. Grip rings are fixedly connected to both ends of the tension band near the first fixing buckles. A locking hole is opened at one end of the tension band near the second fixing buckles, and a hook is engaged on the inner wall of the locking hole. A weight is fixedly connected to the bottom outer wall of the hook. A stretching exercise mechanism is fixedly connected to the top outer wall of the backrest. However, this device, where "a weight is fixedly connected to the bottom outer wall of the hook," relies on the weight at the rear of the top panel for arm rehabilitation training. Since the weight is a fixed weight, it may not be possible to adjust the weight of the guide wheel platform 22 according to the actual needs of the rehabilitation user, which has certain limitations. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing an arm rehabilitation exercise device that allows users to perform arm exercises by pulling a wristband on the front of the guide wheel frame. When the exercise load needs to be adjusted, the counterweight is released by rotating the counterweight nut on the upper part of the screw and pulling the handle groove on the upper part of the counterweight, allowing the counterweight inside the counterweight platform to be detached from the device. This enables the device to adjust the number of counterweights according to the actual load requirements of the rehabilitation user, thereby increasing the adaptability of the device.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An arm rehabilitation exercise device includes a base, a lifting cylinder, a guide cylinder, a lead screw, a front guide wheel frame, a guide wheel shaft, and a steel wire rope.

Beneficial effects

[0009] 1. During the use of this utility model arm rehabilitation exercise device, the arm exerciser can perform arm exercises by pulling the hand ring at the front of the front guide wheel frame. If it is necessary to adjust the exercise load, the counterweight lock can be released by rotating the counterweight nut at the top of the screw and pulling the handle groove at the top of the counterweight, so that the counterweight inside the counterweight platform can be detached from the device. This allows the device to adjust the number of counterweights according to the actual load requirements of the rehabilitation personnel, thereby increasing the adaptability of the device.

[0010] 2. During the use of this utility model arm rehabilitation exercise device, the arm exerciser is trained by pulling the hand ring at the front of the front guide wheel frame. At the same time, the two sets of synchronous gears on the side of the counterweight platform mesh and rotate inside the rack, and guide the counterweight platform with the guide cylinder, so that the two sides of the counterweight platform rise and fall synchronously, avoiding the equipment from jamming when one side is subjected to force, thereby increasing the stability of the equipment.

[0011] 3. During the use of this utility model arm rehabilitation exercise device, the seat on the upper part of the equipment base supports the rehabilitation personnel. If it is necessary to adjust the height of the seat, the locking of the lifting column can be released by disassembling the seat bolts on the side of the lifting cylinder. This allows the equipment to adjust the height of the seat according to the actual height of the rehabilitation personnel, thereby further increasing the adaptability of the equipment.
