Description

Linkage mechanism module of sports rehabilitation equipment

The invention relates to a linkage mechanism module of sports rehabilitation equipment, especially for linking and linking a plurality of components in a sports rehabilitation equipment.

Press, as shown in CN101048204 and CN101791464 in mainland China, it is a kind of training device, wherein the lifting part is a kind of interlocking mechanism. However, the metal processing cost of the second gear and the second bevel gear in the rotation transmission part is high, and the above-mentioned components have to be aligned and connected one by one during assembly, which makes the indirect linkage between many components too complicated and the assembly is also more cumbersome; therefore, the cost of the linkage mechanism increases, which in turn increases the overall cost of the training device. Under the current bad economic environment and meager gross profit, it is really difficult to sell.

Therefore, how to develop and improve the problems of the high cost of the above-mentioned conventional training equipment, so as to truly reduce the overall cost of the conventional training equipment, and at the same time maintain the original use quality of the machine, so as to enhance the competitiveness of sales, is really the goal of research and development that the relevant industries need to work hard on.

In view of the high processing cost of the parts of the conventional training equipment, many components need to be checked and connected one by one during assembly, and the indirect linkage between the components is too complicated and the assembly is also relatively cumbersome, thereby increasing the overall cost of the training equipment, and it is difficult to sell under the request of the buyer to reduce the price.

The present invention provides a linkage mechanism module for sports rehabilitation equipment, including: a frame body, which is at least composed of an upper plate, a lower plate, an upper support frame, and a lower support frame. The upper plate has a perforation. The upper plate and the lower plate; a rotating shaft, which is arranged on the other side of the frame body, and is pivotally connected to the upper plate and the lower plate with two ends; They are respectively pivotally connected to the two fixing frames, and at least one pivot ear is provided on one side. The pivot ear is pivotally connected to one end of the connecting piece and connected to the other end of the cable. Corresponding to the two sides, and for each of the cables to be wound.

The effect of the present invention is: the present invention is mainly to directly link and pull the two cables when the fixed roller rotates, and the two cables pass through 2. After the guide roller is guided, it is directly connected to and linked to the crankshaft actuating part; thereby, the linkage between the rotating handle and the crankshaft actuating part is more direct, the number of connected components can be reduced, the assembly can be quickly and conveniently assembled, and the processing time and assembly cost of the mechanism module can be reduced, and the linkage effect can still be maintained.

In order to enable your examiner to have a further understanding and understanding of the purpose, features and effects of the present invention, please cooperate with the [simplified description of the drawings] to enumerate the embodiments and describe in detail As clear as later:

Please refer to Figures 1 to 8, the present invention provides a linkage mechanism module for sports rehabilitation equipment, including: a frame body 10, which is at least composed of an upper plate 101, a lower plate 102, an upper support frame 103, and a lower support frame 104. The upper plate 101 has a perforation 11. Two corresponding fixed mounts 105 are connected between the frame 103 and the lower support frame 104; a hollow guide tube 20 is open at two ends, and is arranged on one side of the frame body 10, and is vertically fixed on the upper plate 101 and the lower plate 102 with two ends; The corresponding two sides of the wheel 31 are respectively connected with one end of a cable 40; a rotating handle 50 is arranged on the bottom of the lower plate 102 and rotates in a horizontal direction, and is connected and linked to the rotation of the rotating shaft 30; 11. At the same time, one end of the connector 62 is pivotally connected to the other end of the cable 40. The other end of the connector 62 is pivotally connected to one end of the actuating rod 63, and the actuating rod 63 is upwardly passed through the perforation 11 of the upper plate 101. When the crankshaft 61 swings, the connecting member 62 pulls the actuating rod 63 to move up and down in the perforation 11; 3 and the lower support frame 104 are located on the corresponding two sides of the frame body 10, and each of the cables 40 is wound around.

Wherein, the fixed roller 31 is transversely formed with a through hole 33 , and the through hole 33 is penetrated with a fixing part 32 , and two ends of the fixing part 32 are respectively connected to one end of each of the cables 40 .

Wherein, a mandrel 612 is disposed inside the crankshaft 61 , and two ends of the mandrel 612 are respectively pivotally connected to the two fixing frames 105 .

Wherein, the other end of the actuating rod 63 is connected with a tension cable 80 .

Wherein, the hollow guide tube 20 is sleeved with a guide rod 90 .

Wherein, the fixed roller 31 and the guide roller 70 are injection-molded with a plastic mold and made of plastic material.

With the above-mentioned structure and composition design, the operation, use and linkage of the present invention are explained as follows:

Please refer to Figures 9-12 comprehensively. When the user holds the rotating handle 50 and rotates the rotating handle 50 horizontally clockwise or counterclockwise, the rotating shaft 30 and the fixed roller 31 will be rotated synchronously, and one of the cables 40 will be pulled at the same time, and then the crankshaft 61 will be pulled to swing, and the connecting piece 62 will be connected to pull the actuating rod 63 to move up and down in the through hole 11, and the actuating rod 63 will pull the puller. Heavy cable 80.

By the structure of the above-mentioned specific embodiment, the following benefits can be obtained:

(1), the second cable 40 of the present invention is pulled by the rotation of the fixed roller 31, and after passing through two guide rollers 70 respectively, it directly pulls the crankshaft actuating part 60 to move up and down; instead of the linkage mechanism of the conventional training equipment listed in the prior art, it needs to be indirectly linked through a chain, a plurality of spur gears and a plurality of bevel gears. Therefore, the present invention is in this rotary handle 50 and The linkage between the crankshaft actuating parts 60 is more direct.

(2), the hinge assembly among the fixed roller 31, the two cables 40, and the two guide rollers 70 of the present invention is quicker and more convenient. Instead of the linkage mechanism of the conventional training equipment as listed in the prior art, it is necessary to correct the engagement linkage between the chain, the plurality of spur gears and the plurality of bevel gears one by one.

(3), this fixed roller 31 of the present invention, two cables 40 and two guide rollers 70 belong to the general standard spare parts of sports equipment industry in practice, easy to buy and low cost, wherein, this fixed roller 31 and two guide rollers 70 are also injection-molded with plastic molds and are the best for plastic material. In practice, the spur gears and bevel gears of the conventional training equipment listed in the prior art need to be made of metal to have sufficient strength (because the components are small and the strength of the plastic is insufficient). Moreover, the metal spur gears and bevel gears are expensive both in lathe processing cost and material cost, thus resulting in a high cost of the whole training equipment, which is not competitive.

To sum up, the present invention can effectively solve the shortcomings of conventional creation, and can be understood and easily implemented by those of ordinary skill in the technical field. However, the above is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention; that is, all equivalent changes and modifications made according to the scope of the patent application for the present invention should still fall within the scope of the patent of the present invention.
