Detailed Description

The embodiment provides a technical scheme:

as shown in fig. 1 to 4, a wrist tension trainer comprises a bottom fixing seat 1 and a tension trainer, wherein the tension trainer comprises an arc-shaped slide rail 31, a sliding wheel 33, a separation preventing piece for preventing the sliding wheel 33 from separating from the arc-shaped slide rail 31, a U-shaped connecting rod 37 and a handle 39; the inner end of the arc-shaped slide rail 31 is provided with a first sliding tooth portion 32, correspondingly, the side end of the slide wheel 33 is provided with a second sliding tooth portion adapted to the first sliding tooth portion 32, one end of the U-shaped connecting rod 37 is rotatably connected with the center position of the slide wheel 33, and the other end is fixed with the handle 39.

When the patient uses the wrist tension trainer by oneself, the bottom fixing seat 1 can be placed on a table top. Meanwhile, the handle is held by the palm, and force is exerted on the handle in the vertical direction. At this time, the sliding wheel 33 can move along the inner side of the arc-shaped slide rail 31. Due to the function of the anti-dropping piece, the sliding wheel 33 and the arc-shaped sliding rail 31 cannot be accidentally dropped, and the normal use of a patient can be ensured. This wrist portion tension training ware is small not only, and the patient can judge out tensile size of self wrist department according to the distance that movable along arc slide rail 31 of movable pulley 33 moreover, is favorable to observing the tensile training effect of wrist department at any time.

As shown in fig. 2, the anti-dropping element includes a driven wheel 40 and two connecting elements disposed on two sides of the driven wheel 40, and the connecting elements include a first L-shaped connecting rod 34, a first elastic element 35 and a second L-shaped connecting rod 36. One side of the arc-shaped sliding rail 31, which is back to the sliding wheel 33, is provided with a guide rail groove which is matched with the sliding of the driven wheel 40. One end of the first L-shaped link 34 is fixed to the center of the driven wheel 40, the other end is fixed to the first elastic member 35, one end of the second L-shaped link 36 is fixed to the end of the U-shaped link 37 facing away from the handle 39, and the other end is fixed to the first elastic member 35. In this embodiment, the first resilient member 35 may be selected to be of a harder texture to withstand the mass of the driven wheel 40. When the pulley 33 rotates, the driven pulley 40 also rotates together. Because the driven wheel 40 is tightly contacted with the guide rail groove, the sliding wheel 33 will not move by itself if the patient is restrained by the driven wheel 40 under the condition of applying force. To exercise the pulling force at the elbow of the patient, the patient pulls on the handle 39, which deforms the first elastic member 35, thereby serving the purpose of exercising for the patient.

As shown in fig. 2, a bearing 38 is provided in the middle of the sliding wheel 33, and a U-shaped connecting rod 37 is fixed to the inside of the bearing 38.

In this embodiment, a weight member 5 is further included, and a groove adapted to be inserted into the first L-shaped connecting rod 34 is formed in the middle of the weight member 5. After the patient has a good rehabilitation degree, a weight member can be added on the first L-shaped connecting rod 34, so that the training strength of the up-and-down pulling force at the wrist of the patient is added.

This embodiment still includes layer board 2 and the fastener 21 that is used for supporting fixed patient's arm, and end fixing base 1 one end dorsad arc slide rail 31 is equipped with fixed flange 11, and the one end of layer board 2 is articulated with fixed flange 11, and just locks fixedly through fastener 21. The setting of layer board 2 can make things convenient for the patient to place the arm more, and the patient can be according to the actual need of self simultaneously, adjusts layer board 2's angle at any time to make the training process more comfortable.

In the present embodiment, the handle 39 is provided with five arcuate protrusions 390, and a gap adapted to the gap between two fingers is formed between two adjacent arcuate protrusions 390.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
