Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation training technology, and in particular to an arm-raising rehabilitation training device. Background Technology
[0002] An arm-raising rehabilitation training device is a device used to assist patients with arm dysfunction in rehabilitation training. Existing devices are numerous and varied. In most existing devices, the arm-raising rehabilitation training device requires the patient to hold it with both hands for rehabilitation training; otherwise, due to the counterweights at both ends, it is difficult to maintain balance of the training bar during single-handed training. This makes it unsuitable for people who only need to train one arm or for people with disabilities who only have one arm. Furthermore, typical training devices can only accommodate one person at a time, failing to meet the needs of two people training simultaneously. Therefore, this arm-raising rehabilitation training device is proposed. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing arm-raising rehabilitation training devices, which require patients to hold the device with both hands for rehabilitation training. This makes it unsuitable for people who only need to train one arm or people with disabilities who only have one arm. Furthermore, general training devices cannot meet the needs of two people training at the same time. Therefore, this invention proposes an arm-raising rehabilitation training device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An arm-raising rehabilitation training device includes two training rods and a connecting rod. Multiple mounting holes are formed on the surface of each training rod. A locking component is installed in two of the mounting holes. Each locking component includes a pin rod that engages within the mounting hole. A pin cap is fixedly connected to the top of the pin rod. A pin sleeve is slidably connected to the outer circumference of the pin rod, abutting against the training rod. A return spring is fixedly connected to the inner bottom wall of the pin sleeve, sleeved around the circumference of the pin rod. The other end of the return spring is fixedly connected to the inner top wall of the pin rod. A pin sleeve is also sleeved around the circumference of the pin rod, with a return spring fixedly connected to the bottom of the pin sleeve. The return spring sleeve is also located around the circumference of the pin rod.
[0006] Limiting component, which is located at the bottom of the connecting rod and is used in conjunction with the training rod;
[0007] It also includes two connecting mechanisms, which are disposed on the surface of the training bar for connecting the training bar and the connecting rod.
[0008] In one possible design, the limiting component includes two vertical rods, which are fixed to the bottom of the connecting rod. The two vertical rods have multiple insertion holes around their circumferences, some of which are used to insert rods. The two vertical rods are fixedly connected to the same base.
[0009] In one possible design, protective covers are fixedly connected to both ends of the connecting rod, and two mounting rods are fixedly connected to the inner walls of both sides of the protective covers. A spiral spring is fixedly connected to the circumference of each of the two mounting rods, and an elastic rope is fixedly connected to one end of the spiral spring.
[0010] In one possible design, the connecting mechanism includes a mounting groove disposed on the surface of the training bar. A connecting rod is fixedly connected between the inner walls of both sides of the mounting groove. A connecting ring is provided on one side of the connecting rod. A connecting block is fixedly connected to one end of the connecting ring. One end of the connecting block is fixedly connected to the other end of the elastic rope. A buckle is rotatably connected to one side of the connecting block. One end of the buckle engages with the connecting ring. A torsion spring is provided between the buckle and the connecting ring.
[0011] In one possible design, the training bar is circumferentially fitted with multiple counterweight rings.
[0012] In one possible design, both ends of the training rod are threaded to connect with the counterweight ring.
[0013] In one possible design, the training bar is circumferentially fitted with two limiting rings, and a rubber protective sleeve is fixedly connected between the two limiting rings.
[0014] In this application, before use, different weights are installed according to the patient's required exercise level. For two-handed training, the weights can be tightened onto the threads at both ends of the training rod. For one-handed training, the connecting mechanism and locking component need to be removed, and then the weights are placed on the training rod (the weights can be placed on the training rod by rotating past the threaded section). Then, the locking component is tightened again to fix the weights, and the connecting mechanism is fastened onto the connecting rod to begin training. During training, the patient stands on one side of the device, holds the training rod, lifts it upwards, places it on the insertion rod, and then removes the training rod and places it on the upper insertion rod. This process is repeated to achieve the training purpose.
[0015] When the user wants to remove the locking component, simply pinch the pin cap, press it down while rotating it 90°. When pressed down, the spring contracts, causing the pin to move downwards and disengage from the inner wall of the mounting hole. Then, when the horizontal bar at the lower end of the pin aligns with the square hole at the top of the mounting hole, the locking component can be removed. To lock it, insert the pin into the mounting hole and rotate it. The spring will hold the pin in place to prevent it from loosening. To open the connecting mechanism, push the latch inwards. The torsion spring inside the latch will move accordingly. Then, rotate the connecting ring to disengage it from the connecting rod. Release your hand, and the latch will automatically close under the action of the torsion spring.
[0016] Beneficial effects: In this utility model, the arm raising rehabilitation training device allows the user to install the counterweights on both sides or near the middle, so as to facilitate the use of one or both hands during exercise. This solves the problem that some people who only need to train one arm or disabled people with only one arm cannot hold it steadily and are prone to dropping it during use.
[0017] In this utility model, the arm raising rehabilitation training device has a recessed area on the rod body, which makes it convenient for the patient to place the training rod on the rod and prevents the training rod from rolling down and accidentally injuring the patient.
[0018] In this invention, two sets of training rods and other components are symmetrically arranged at the front and back of the vertical rod, allowing two people to train simultaneously, saving costs and space. Attached Figure Description
