[0036] Example 1: See Figure 1-Figure 5 The present invention provides a technical solution: a pull-up combined body measurement device, comprising two groups of load-bearing blocks 1, the inner walls of the two groups of load-bearing blocks 1 are fixedly connected with vertical rods 2, the top outer walls of the two groups of vertical rods 2 are provided with cross bars 3, the cross bars 3 penetrate the two groups of vertical rods 2, and are fixedly connected with the two groups of vertical rods 2, and also includes:

[0037] The reset mechanism 4 comprises two groups of fixing rings 401, the inner walls of the two groups of fixing rings 401 are fixedly connected to the outer wall of the cross bar 3, the top inner walls of the two groups of fixing rings 401 are provided with sliding bars 403, the tops and bottoms of the two groups of sliding bars 403 are fixedly connected to the top inner walls of the fixing rings 401, the two groups of fixing rings 401 are fixedly connected with fixing blocks 402 on the sides away from each other, the tops of the two groups of fixing blocks 402 are fixedly connected with second rotating blocks 407, the tops of the two groups of second rotating blocks 407 are provided with moving blocks 408, the bottoms of the two groups of moving blocks 408 are in contact with the second rotating blocks 407, the tops of the two groups of moving blocks 408 are respectively provided with four groups of bolts 409, and the eight groups of bolts 409 all penetrate the moving blocks 408, and the position of the moving blocks 408 can be adjusted by setting the bolts 409, so that the magnetic blocks 411 on the moving blocks 408 and the magnetic blocks 411 on the first rotating blocks 404 will be moved closer to each other due to different positions. , the positions are different, so the repulsive forces are also different, thereby improving the flexibility of the two magnetic blocks 411, and fixedly connected with them, the bottoms of the eight groups of bolts 409 are fixedly connected to the bottom of the second rotating block 407, the middle ends of the tops of the two groups of moving blocks 408 are fixedly connected with the positioning shell 410, the bottoms of the inner walls of the two groups of positioning shells 410 are fixedly connected with the magnetic blocks 411, the sides of the two groups of second rotating blocks away from the fixed ring 401 are rotatably connected with the first rotating blocks 404 through bearings, and the sides of the two groups of first rotating blocks 404 close to the fixed ring 401 are fixedly connected with four groups of first springs 405, and the first springs 405 are provided to fix the bottom of the limiting shell 406, so that the magnetic block 411 in the limiting shell 406 will not fall off during rotation, and the sides of the eight groups of first springs 405 close to the fixed ring 401 are respectively fixedly connected to the limiting shell 406, and the reset mechanism 4 is set in two groups and is symmetrically arranged with the middle part of the cross bar 3 as the center.

[0038] The working principle of this embodiment is as follows: first, the vertical rod 2 is inserted into the load-bearing block 1. Then, the staff can insert the fixing pin into the insertion plate, the load-bearing block 1 and the inner wall at the bottom of the vertical rod 2 to achieve preliminary fixation. Subsequently, the four sets of fixing rings 401 are inserted into the cross bar 3. After the four sets of fixing rings 401 and the cross bar 3 are perfectly combined, the left and right ends of the cross bar 3 are firmly connected to the vertical rod 2. At this point, the equipment assembly is complete. When the equipment needs to be tested, the tester puts his palm in contact with the pull rod 506. At this time, the pull rod 506 will move downward due to the weight of the human body. During the downward movement of the pull rod 506, During the movement, the second spring 505 will be driven to move together. The second spring 505 will be displaced downward under the action of the pulling force. When it moves downward, it will drive the curved rod 504 to move toward the direction of the protective shell 501. The curved rod 504 will press the airbag 503 during the movement, so that the airbag 503 will move closer to the protective shell 501. In this way, the gas in the airbag 503 will flow into the inside of the protective shell 501. The gas will then push the magnesium powder in the protective shell 501 into the arc tube 507, and then be pushed out from the arc tube 507, so that the magnesium powder adheres to the hand of the tester, thereby achieving a good anti-slip effect.

[0039] Example 2: Please refer to Figure 6-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: an anti-skid mechanism 5, the anti-skid mechanism 5 includes a protective shell 501, the bottom of the protective shell 501 is fixedly connected to the tops of the two sets of fixing rings 401, and two sets of opening and closing plates 502 are arranged on the top of the protective shell 501. The two sets of opening and closing plates 502 are hinged to the protective shell 501 on one side close to the protective shell 501, and a separation block 508 is fixedly connected to the middle end of the inner wall of the protective shell 501. By setting the separation block 508, the magnesium powder in the protective shell 501 can be separated, and the internal space of the protective shell 501 can be isolated, so that the magnesium powder can be better moved when pushed by the gas. The left and right sides of the inner wall of the protective shell 501 are connected with arc tubes 507, and the protective The left and right sides of the shell 501 are fixedly connected with air bags 503. By setting the air bags 503, the gas can be compressed by the air bags 503 so that the gas pushes the magnesium powder to move and spray out, so that it just contacts the tester, thereby achieving an anti-slip effect. The two groups of air bags 503 are fixedly connected with a curved rod 504 on the side away from the protective shell 501, and the two groups of curved rods 504 are slidingly connected to the sliding rod 403 on the side close to the protective shell 501. The two groups of curved rods 504 are fixedly connected with a second spring 505 on the side close to each other, and the two groups of second springs 505 are fixedly connected with a pulling rod 506 on the side close to each other. The anti-slip mechanism 5 is set to two groups and is symmetrically arranged with the middle of the cross bar 3 as the center.

[0040] The working principle of this embodiment is as follows: when the curved rod 504 moves, it drives the first rotating block 404 to move toward the direction of the protective shell 501, so that the first rotating block 404 continuously approaches and fits with the second rotating block 407. During this process, the first rotating block 404 in the limiting shell 406 drives the limiting shell 406 to fit with the positioning shell 410. At this time, the magnetic block 411 inside the limiting shell 406 and the magnetic block 411 inside the positioning shell 410 are close to each other and generate repulsive force. At the same time, the first spring 405 begins to shrink, effectively preventing the magnetic block 411 inside the limiting shell 406 from falling off, thereby ensuring that the magnetic block 411 can achieve the resetting function by mutual repulsion, thereby avoiding the failure to achieve this important function due to the falling of the magnetic block 411.

[0041] Example 3: Please refer to Figure 9-10 On the basis of the first and second embodiments, the present invention provides a technical solution: a clamping mechanism 6, the clamping mechanism 6 includes four groups of pressing blocks 601, the bottoms of the four groups of pressing blocks 601 are fixedly connected to the top of the moving block 408, the sides of the four groups of pressing blocks 601 close to each other are fixedly connected with contact blocks 602 through fixing pins, the sides of the two groups of contact blocks 602 away from the pressing blocks 601 are fixedly connected with clamping blocks 604, the inner walls of the two groups of clamping blocks 604 away from the contact blocks 602 are slidably connected with insertion blocks 605, the bottoms of the inner walls of the two groups of insertion blocks 605 are fixedly connected with two groups of third springs 606, and the push rod can be adjusted by setting the third springs 606. 607 is continuously pushed, so that the push rod 607 can always contact the inner wall of the block 604, thereby preventing the insertion block 605 from moving. The tops of the four groups of third springs 606 are respectively fixedly connected with the push rods 607. The two groups of push rods 607 are in contact with the inner wall of the block 604. By setting the push rods 607, the connection relationship between the block 604 and the insertion block 605 can be solved by the height value of the push rods 607. The side of the insertion block 605 away from the contact block 602 is fixedly connected with a push block 603. The push block 603 is in contact with the magnetic block 411. The clamping mechanism 6 is set to two groups and is symmetrically arranged with the middle of the cross bar 3 as the center.

[0042] The working principle of this embodiment is as follows: after the staff has placed the magnetic block 411 inside the positioning shell 410, the push rod 607 can be pressed downward. Once the push rod 607 is pressed down to a state where it is no longer in contact with the inner wall of the card block 604, the third spring 606 will shrink rapidly. Under this shrinkage, the insertion block 605 can move steadily in the direction of the magnetic block 411 and continue to move forward until it is in close contact with the side wall of the magnetic block 411. At this time, the staff stops pressing the push rod 607, and the third spring 606 immediately begins to rebound, forcefully pushing the push rod 607 to contact the inner wall of the card block 604 again, thereby successfully completing the fixing work. In this way, it can be ensured that the second rotating block 407 will not slip during the rotation process. Furthermore, the carefully arranged bolt 409 can more effectively enable the moving block 408 to perform a shifting operation. With the help of different position adjustments, the two magnetic blocks 411 can present different repulsion effects.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
