[0023] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0024] like Figures 1 to 6 As shown, an embodiment of the present invention provides a disassembly and assembly structure comprising a connecting base 1 and a mounting base 2; wherein the connecting base 1 has a connecting portion 3, and the mounting base 2 has a mounting groove 4 that cooperates with the connecting portion 3. An elastic clip is further provided in the mounting base 2, and a slot that cooperates with the elastic clip is provided on the connecting portion 3. When the connecting portion 3 moves in the mounting groove 4 to a position where the slot and the elastic clip are opposite, a portion of the elastic clip enters the slot, thereby achieving a fixed connection between the connecting base 1 and the mounting base 2.

[0025] A groove 5 for accommodating the elastic clip is provided in the mounting base 2, and the groove 5 is communicated with the mounting groove 4. A detachable limiting plate 6 is also provided on the mounting base 2. The limiting plate 6 is used to limit the elastic clip in the groove 5. Specifically, the limiting plate 6 is fixed to the mounting base 2 by bolts. After the elastic clip is installed, the limiting plate 6 is fixed to the mounting base 2, thereby limiting the elastic clip and preventing it from shaking up and down without affecting its normal operation.

[0026] Specifically, the elastic clamp of this embodiment includes a rod 7 and a spring 8. One end of the spring 8 is connected to the inner wall of the groove 5, and the other end is connected to the rod 7. The two ends of the rod 7 are respectively a release portion 9 and a fixing portion 10. The release portion 9 extends out of the mounting seat 2, and the fixing portion 10 extends into the mounting groove 4.

[0027] In addition, during the process of inserting the connecting portion 3 into the mounting groove 4, the end of the connecting portion 3 first contacts the fixing portion 10 of the elastic clamp and pushes the fixing portion 10 to compress the spring 8. To facilitate this operation, the contact surface between the connecting portion 3 and the elastic clamp in this embodiment is an inclined surface.

[0028] In some other embodiments, the contact surface between the fixing portion 10 and the connecting portion 3 is an inclined surface. Of course, both of them may be provided with an inclined surface.

[0029] In order to further improve the connection stability between the connecting base 1 and the mounting base 2, the connecting portion 3 of this embodiment is a dovetail block, and the outer diameter of the connecting portion 3 gradually tapers along its installation direction, and the mounting groove 4 matches the outer shape of the connecting portion 3. In this case, the installation direction of the connecting base 1 and the mounting base 2 is restricted, but the stability of the two is better achieved, avoiding adverse effects on training;

[0030] This embodiment also provides a multi-joint isokinetic training device, comprising a rotating portion, a joint training portion, and the aforementioned disassembly and assembly structure. The connecting seat 1 or the mounting seat 2 of the disassembly and assembly structure is connected to the rotating portion. When the mounting seat 2 is connected to the rotating portion, the connecting seat 1 is provided with a mounting hole 11 connected to the rotating arm of the joint training portion.

[0031] In addition, a bolt / screw groove 12 for cooperating with a fixing bolt / screw is provided on the mounting seat 2. The bolt / screw groove 12 is located on the groove surface of the mounting groove 4. Therefore, even if the bolt / screw becomes loose, it will be blocked by the connecting seat 1 and cannot fall off, thereby further improving the overall stability of the multi-joint isokinetic training device.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit and essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
