Description

Technical Field

[0001] The utility model specifically relates to a wrist joint and elbow joint training device. Background Technique

[0002] An elbow joint trainer is a device specifically designed to help restore and enhance elbow function. It is used among athletes, patients undergoing rehabilitation treatment, fitness enthusiasts and other people who need to perform high-intensity upper limb activities, aiming to enhance muscle strength, improve joint flexibility, and enhance elbow stability.

[0003] The existing elbow joint trainers can only train the elbow joint. When the wrist joint adjacent to the elbow joint needs to be trained, another device needs to be replaced, which costs more for the device, has a relatively single use, is not convenient for training both well, and it is also a waste of time to train the wrist joint separately, and it is not convenient to train both at the same time. For this reason, we propose a wrist joint and elbow joint training device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wrist joint and elbow joint training device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A wrist joint and elbow joint training device, comprising:

[0006] A base;

[0007] A bracket, fixed to one end of the upper surface of the base, and a support pad for placing the arm is arranged on the bracket;

[0008] A connecting arm, rotatably installed at the upper end of one side wall of the bracket, and a damper connected to the bracket is arranged on the lower surface of the connecting arm to train the elbow joint;

[0009] A rotating shaft, rotatably installed at one end of the connecting arm;

[0010] A torsion assembly, fixed to the lower end inside the rotating shaft, and a grip assembly is arranged at the top of the torsion assembly.

[0011] Preferably, the torsion assembly includes a rotating rod, a sleeve, a torsion spring and a sealed bearing. The sleeve is fixed to the inside of the rotating shaft, and the rotating rod is rotatably connected to the inside of the sleeve through the sealed bearing. A torsion spring is sleeved on the outer surface of the rotating rod, and both ends of the torsion spring are respectively matched with the rotating rod and the sleeve.

[0012] Preferably, the lower surface of the sleeve is connected with an adjusting bolt through a threaded part. A plurality of grooves are formed in the circumferential direction of the lower surface of the rotating rod, and the adjusting bolt is matched with the grooves.

[0013] Preferably, the handle assembly includes a connecting plate and a handle rod. The connecting plate is fixed to the upper end of the torsion assembly, and two handle rods are arranged side by side on the upper surface of the connecting plate.

[0014] Preferably, the handle rod is "L"-shaped, and a soft pad is sleeved on the outer surface of the handle rod.

[0015] Preferably, a telescopic rod is fixed to the other end of the upper surface of the base, and a seat cushion is arranged at the top of the telescopic rod.

[0016] Preferably, shock-absorbing foot pads are arranged on the lower surface of the base.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a rotating rod, a sleeve and a torsion spring, it is avoided that only single elbow joint training can be carried out during training. When performing additional wrist joint training, it is necessary to replace the equipment separately, which is rather troublesome. This device can realize the simultaneous training of the elbow joint and the wrist joint on one device, improving the diversity of the device. At the same time, the simultaneous training also improves the training efficiency, saving the time for the user to perform additional wrist joint training. The device has a simple structure, is easy for the user to use, and increases the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a wrist joint and elbow joint training device, comprising:

[0026] Base 1;

[0027] Bracket 7, fixed to one end of the upper surface of the base 1, and a support pad 4 for placing the arm is provided on the bracket 7;

[0028] Connecting arm 5, rotatably installed at the upper end of one side wall of the bracket 7, and a damper 6 connected to the bracket 7 is provided on the lower surface of the connecting arm 5 to train the elbow joint, facilitating the training of the elbow joint through resistance;

[0029] Rotating shaft 9, rotatably installed at one end of the connecting arm 5, facilitating the bending of the elbow joint towards the user during training;

[0030] Torque assembly 10, fixed to the lower end inside the rotating shaft 9, and a handle assembly 11 is provided at the top of the torque assembly 10, facilitating the training of the user's wrist by overcoming the torque.

[0031] In this embodiment, preferably, the torque assembly 10 includes a rotating rod 101, a sleeve 102, a torsion spring 103 and a sealed bearing 105. The sleeve 102 is fixed to the inside of the rotating shaft 9, and the rotating rod 101 is rotatably connected to the inside of the sleeve 102 through the sealed bearing 105. A torsion spring 103 is sleeved on the outer surface of the rotating rod 101, and the two ends of the torsion spring 103 are respectively matched with the rotating rod 101 and the sleeve 102, facilitating the rotation of the rotating rod 101 by the wrist joint to overcome the elastic torque of the torsion spring 103 and complete the training of the wrist joint.

[0032] In this embodiment, preferably, the lower surface of the sleeve 102 is connected with an adjusting bolt 104 through a threaded portion. A plurality of grooves are formed on the lower surface of the rotating rod 101 along its circumference, and the adjusting bolt 104 is matched with the grooves, facilitating the adjustment of the rotation state of the rotating rod 101.

[0033] In this embodiment, preferably, the handle assembly 11 includes a connecting plate 111 and a handle rod 112. The connecting plate 111 is fixed to the upper end of the torque assembly 10, and two handle rods 112 are arranged side by side on the upper surface of the connecting plate 111, facilitating the holding of both palms to train both elbow joints simultaneously.

[0034] In this embodiment, preferably, the handle rod 112 is in an "L" shape, and a soft pad is sleeved on the outer surface of the handle rod 112 to facilitate the softness of holding.

[0035] In this embodiment, preferably, a telescopic rod 2 is fixed to the other end of the upper surface of the base 1, and a seat cushion 3 is arranged at the top of the telescopic rod 2.

[0036] In this embodiment, preferably, shock-absorbing foot pads 8 are arranged on the lower surface of the base 1.

[0037] The working principle and usage process of the present utility model: When in use, the user can adjust the height of the seat cushion 3 through the telescopic rod 2, then sit on the seat cushion 3, place the arms on the support pads 4, and then hold the two handle rods 112 with both hands. Bend the elbows towards the user's side to lift one end of the connecting arm 5 upward. At this time, through the resistance of the damper 6, the elbows can be trained. Further, when it is necessary to exercise the wrist joints, the adjusting bolt 104 can be screwed out from the inner side of the groove. At this time, the user holds the handle rod 112 and rotates the rotating rod 101 towards the user's side through the wrist joints. At this time, the torsion spring 103 is distorted, and the elastic resistance of the torsion spring 103 is used to train the user's wrist joints, improving the diversity of the device. Further, the user can also train the elbows and wrist joints simultaneously to improve the training efficiency.
