[0022] One end of the main rod 204 is hinged on the first sliding rod 201, and the hinged end can be detachably installed with a second screw 206.

[0028] When the device is not in use, firstly, the second support rod 303 on the device is taken out from the first slot 2041, and the second telescopic rod 301 is taken out from the second slot 2071, so that the hinge point between the crossbeam 207 and the main rod 204 can rotate, then the second screw 206 and the third screw 2061 are unscrewed to make the main rod 204 and the first telescopic rod 205 rotatable, and finally the first screw 102 is unscrewed to make the first sliding rod 201 and the second sliding rod 202 slide in the frame 1, and the first sliding rod 201 and the second sliding rod 202 are slid to the left side of the frame 1, so that the main rod 204 and the first telescopic rod 205 rotate clockwise and approach the frame 1, and the crossbeam 207 rotates counterclockwise and approaches the frame 1, and the folding of the device is completed.

[0029] In order to realize the function of the device being able to adjust different resistances, an aerobic testing device for exercise physiology is proposed, wherein the adjustment mechanism 4 includes: a mounting shell 401, a third telescopic rod 402, and a wedge block 407. The mounting shell 401 is fixedly connected to the outer surface of the wheel shell 302, and the fixed rod end of the third telescopic rod 402 is fixedly connected to the inner upper surface of the mounting shell 401. The third telescopic rod 402 adopts an electric telescopic rod, and the movable rod end of the third telescopic rod 402 is fixedly connected to the upper surface of the displacement block 403. The displacement block 403 is in the mounting shell 401, and the extension and retraction of the third telescopic rod 402 can drive the displacement block 403 to move up and down in the mounting shell 401.

[0030] One end of a push rod 404 is fixedly connected to both sides of the lower surface of the displacement block 403. There are two push rods 404. The other end of each push rod 404 extends into the runner housing 302 and is fixedly connected to a wedge block 407. One end of a first spring 405 is fixedly connected to the middle of the lower surface of the displacement block 403. The other end of the first spring 405 is fixedly connected to the outer surface of the runner housing 302. A fourth telescopic rod 406 is sleeved inside the first spring 405. One end of the fourth telescopic rod 406 is fixedly connected to the lower surface of the displacement block 403, and the other end is fixedly connected to the outer surface of the runner housing 302. The fourth telescopic rod 406 adopts an ordinary telescopic rod;

[0031] When the displacement block 403 moves upward in the mounting shell 401, the first spring 405 extends under the action of the pulling force of the displacement block 403, and the fourth telescopic rod 406 extends. On the contrary, when the displacement block 403 moves downward in the mounting shell 401, the first spring 405 is compressed under the action of the pulling force of the displacement block 403, and the fourth telescopic rod 406 is shortened. The displacement block 403 moves up and down in the mounting shell 401, driving the push rod 404 to move up and down, and the wedge block 407 fixedly connected to the push rod 404 moves up and down in the rotor shell 302.

[0032] The inclined surface of the wedge block 407 is in contact with the inclined surface of the extrusion block 408, the extrusion block 408 is in an inverted trapezoid, the other surface of the extrusion block 408 is fixedly connected to one end of the second spring 409, the other end of the second spring 409 is fixedly connected to the fixed rod 410, the second spring 409 is sleeved on the outer surface of the fifth telescopic rod 4091, one end of the fifth telescopic rod 4091 is fixedly connected to the extrusion block 408, and the other end is fixedly connected to the fixed rod 410, the fixed rod 410 is fixedly connected to the inner surface of the runner shell 302, a limit rod 4101 is arranged at the lower end of the fixed rod 410, the limit rod 4101 limits the moving distance of the extrusion block 408, and the fifth telescopic rod 4091 adopts an ordinary telescopic rod;

[0033] In the initial state, the second spring 409 is in a semi-compressed state. When the wedge block 407 moves downward, the wedge block 407 gradually moves to the lower end of the inclined surface of the extrusion block 408, the pressure on the extrusion block 408 is reduced, and the second spring 409 gradually extends. Under the thrust of the second spring 409, the fifth telescopic rod 4091 extends accordingly, and the extrusion block 408 moves toward the direction close to the wedge block 407, so that the inclined surface of the extrusion block 408 and the wedge block 407 remain in contact.

[0034] The lower end of the wedge block 407 is fixedly connected to the clamping block 411, which is located on both sides of the rotating wheel 304. The clamping block 411 is fixedly connected to the friction pad 412 close to the side surface of the rotating wheel 304, and the clamping block 411 is fixedly connected to the limit block 4111, which limits the moving distance of the wedge block 407.

[0035] When the squeezing block 408 moves toward the direction approaching the wedge block 407 , the clamping block 411 gradually moves toward the direction approaching the rotating wheel 304 , and gradually clamps the rotating wheel 304 , thereby increasing the friction force between the rotating wheel 304 and the friction pad 412 , thereby increasing the friction force.

[0036] Working principle:

[0037] When the device is not in use, firstly, the second support rod 303 on the device is taken out from the first slot 2041, and the second telescopic rod 301 is taken out from the second slot 2071, so that the hinge point between the crossbeam 207 and the main rod 204 can rotate, then the second screw 206 and the third screw 2061 are unscrewed to make the main rod 204 and the first telescopic rod 205 rotatable, and finally the first screw 102 is unscrewed to make the first sliding rod 201 and the second sliding rod 202 slide in the frame 1, and the first sliding rod 201 and the second sliding rod 202 are slid to the left side of the frame 1, so that the main rod 204 and the first telescopic rod 205 rotate clockwise and approach the frame 1, and the crossbeam 207 rotates counterclockwise and approaches the frame 1, and the folding of the device is completed.

[0038] On the contrary, when using the present device, first slide the first sliding rod 201 to the middle of the frame 1, slide the second sliding rod 202 to the right side of the frame 1, screw in the first screw 102, rotate the main rod 204 and the first telescopic rod 205 counterclockwise, and after the crossbeam 207 on the main rod 204 reaches a suitable height, screw in the second screw 206 and the third screw 2061, and when the crossbeam 207 is rotated to a horizontal state, insert the second support rod 303 into the first slot 2041, and insert the second telescopic rod 301 into the second slot 2071 to complete the support between the crossbeam 207 and the main rod 204, so that the crossbeam 207 remains horizontal and no longer rotates, and the installation of the present device is completed.

[0039] When it is necessary to adjust the resistance of the rotating wheel 304, when the third telescopic rod 402 is extended, the wedge block 407 moves downward, and the wedge block 407 gradually moves to the lower end of the inclined surface of the extrusion block 408, the pressure on the extrusion block 408 is reduced, and the second spring 409 gradually extends. Under the action of the thrust of the second spring 409, the fifth telescopic rod 4091 extends accordingly, and the extrusion block 408 moves toward the direction close to the wedge block 407. When the extrusion block 408 moves toward the direction close to the wedge block 407, the clamping block 411 gradually moves toward the direction close to the rotating wheel 304 and gradually clamps the rotating wheel 304, thereby increasing the friction between the rotating wheel 304 and the friction pad 412, and increasing the friction force.

[0040] On the contrary, the third telescopic rod 402 is shortened, the wedge block 407 moves upward, the second spring 409 is gradually compressed, the squeezing block 408 moves away from the wedge block 407, the clamping block 411 gradually moves away from the rotating wheel 304, the rotating wheel 304 is gradually loosened, and the friction between the rotating wheel 304 and the friction pad 412 is reduced.

[0041] The user wears the sample test device, holds the operating handle 6, and steps on the pedal 305 to perform the sample test.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
