[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0032] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Embodiment 1: Refer to Figures 1-6 , the present invention provides a technical solution: A sit-and-reach test device for physical fitness measurement, including a bottom plate 1, a protective shell 2 is fixedly connected to the right side of the top of the bottom plate 1, a measuring block 3 is fixedly connected to the middle end of the top of the protective shell 2, a sliding block 4 is arranged inside the measuring block 3, the bottom of the sliding block 4 is slidably connected to the inner wall of the measuring block 3, an arc plate 5 is fixedly connected to the right side of the inner wall of the protective shell 2, two groups of germicidal lamps 6 are arranged on the arc plate 5, and both the front and back sides of the two groups of germicidal lamps 6 are fixedly connected to the arc plate 5. It also includes:

[0034] Rotating mechanism 7, the rotating mechanism 7 includes two groups of contact plates 701. By setting two groups of contact plates 701, they can be used alternately when disinfecting the plate surfaces of the contact plates 701. The advantage at this time is that it will not delay the time of the testers, so that the testers can conduct tests quickly and orderly. The outer periphery of the contact plate 701 on the left side is in contact with the protective shell 2. On the sides where the two groups of contact plates 701 are close to each other, connecting rods 702 are respectively fixedly connected. At the top of the connecting rod 702, there is a slide bar 709. By setting the slide bar 709, the sliding ring 707 can slide on the slide bar 709 without hindrance. In this way, when the sliding ring 707 slides, the contact plate 701 can be turned over better. On the outer wall of the slide bar 709, there are fixed blocks 704. The bottom of the fixed block 704 is rotatably connected to a rotating plate 705 through a rotating shaft. The bottom of the rotating plate 705 is rotatably connected to a rotating rod 703 through a rotating shaft. The side of the rotating rod 703 away from the rotating plate 705 is fixedly connected to the top of the connecting rod 702. On one side of the fixed block 704 close to the arc-shaped plate 5, there are two groups of hook plates 706. By setting the hook plates 706, they can be in contact with the pull ring 804, so as to judge whether the sliding ring 707 will be pulled by whether the hook plates 706 are in contact with the pull ring 804. The two groups of hook plates 706 are respectively fixedly connected to the front and back sides of the fixed block 704. On one side of the fixed block 704 close to the arc-shaped plate 5, a sliding ring 707 is fixedly connected. On the front and back sides of the outer wall of the sliding ring 707, push rods 708 are fixedly connected.

[0035] The working principle of this embodiment is as follows: When a tester needs to conduct a test, first take off shoes and sit on the bottom plate 1 with legs facing the protective shell 2, and place both hands on the sliding block 4 and push it into the measuring block 3. When the tester pushes the sliding block 4, the sole of the foot will generate a forward thrust on the contact plate 701, and the contact plate 701 moves into the protective shell 2. During the movement, the contact plate 701 pushes the connecting rod 702 to move synchronously. The connecting rod 702 drives the top rotating plate 705 to move through the rotating rod 703. The rotating plate 705 pushes the fixed block 704. When the fixed block 704 moves, it pushes the sliding ring 707. The sliding ring 707 pushes the push rod 708 to move and slide on the slide bar 709. Under the thrust of the tester, the contact plate 701 will deflect by a small angle through the rotating rod 703, and thus the relevant test work is completed.

[0036] Embodiment Two: Please refer to Figures 7-8, on the basis of the first embodiment, the present invention provides a technical solution: further including a pulling mechanism 8, the pulling mechanism 8 includes a fixed ring 801, and a fixed ring 801 is fixedly connected to the side of the arc plate 5 close to the contact plate 701. On both the front and back sides of the fixed ring 801, there are fixedly connected baffles 802, and the two groups of baffles 802 are fixedly connected to the side close to the arc plate 5. On the side of the two groups of baffles 802 away from the arc plate 5, there are fixedly connected first springs 803. By setting the first springs 803, the pull ring 804 can be pulled, thereby driving the hook plate 706 to move. This will cause the contact plate 701 to move quickly, and thus it will flip due to the centrifugal force. On the side of the two groups of first springs 803 away from the arc plate 5, there are fixedly connected pull rings 804, and the inner walls of the two groups of pull rings 804 are in contact with the hook plate 706. On the outer wall of the side of the fixed ring 801 away from the baffle 802, there are fixedly connected two groups of ejector rods 805. On the side of the two groups of ejector rods 805 away from the baffle 802, there is a protective shell 806. The inner walls of the two groups of protective shells 806 are slidably connected to the outer walls of the ejector rods 805. On the side of the two groups of ejector rods 805 close to the protective shell 806, there are fixedly connected second springs 807. By setting the second springs 807, the moved moving block 809 can be reset, so that the moving block 809 will drive the bent rod 808 to contact the ejector rod 805 again. On the side of the two groups of second springs 807 away from the ejector rod 805, there are fixedly connected moving blocks 809. On both the front and back sides of the two groups of moving blocks 809, there are rotatably connected bent rods 808 through rotating shafts. On the side of the four groups of bent rods 808 close to the ejector rod 805, they are in contact with the inner wall of the ejector rod 805.

[0037] The working principle of this embodiment is as follows: When the push rod 708 continues to move forward and contacts the moving block 809, it will push the moving block 809 to move in a direction away from the contact plate 701. During the movement of the moving block 809, it will press the second spring 807, causing it to contract. At the same time, the movement of the moving block 809 will also cause the bent rod 808 to rotate in a direction away from the protective shell 806, gradually moving away from the ejector rod 805 until they no longer contact. At this time, the pull ring 804 is no longer restricted by the bent rod 808, and the resilience of the first spring 803 starts to pull the hook plate 706. Specifically, the first spring 803 first pulls the pull ring 804, and the pull ring 804 then pulls the hook plate 706, causing the sliding ring 707 to continue sliding on the sliding rod 709, and further causing the contact plate 701 to move again. Under the pull of the first spring 803, the contact plate 701 is subjected to a huge pulling force, thus completing the flip.

[0038] Embodiment Three: Please refer to Figure 9, on the basis of the first and second embodiments, the present invention provides a technical solution: further comprising a straightening mechanism 9, the straightening mechanism 9 includes a fitting block 901, the fitting block 901 is fixedly connected to the inner wall of the protective shell 2 on the reverse side, a groove 902 is opened on the side of the fitting block 901 close to the rotating mechanism 7, the right side of the groove 902 wall is rotatably connected to an inclined block 905 through a rotating shaft, by setting the inclined block 905, it will also start to slowly rotate towards the direction of the groove 902 under the push of the third spring 904, so as to give the effect of maintaining the original state when the contacted object is turned over. A third spring 904 is arranged on the inner wall of the inclined block 905. By setting the third spring 904, the arc-shaped block 906 can be pushed in the reverse direction, so that the arc-shaped block 906 can perform a reset movement under the push of the third spring 904, and the arc-shaped block 906 will always be in contact with the side wall of the contact plate 701, so that the contact plate 701 will be slowly straightened by the movement of the arc-shaped block 906. The right side of the third spring 904 is fixedly connected to the inclined block 905, and the left side of the third spring 904 is fixedly connected to the arc-shaped block 906. By setting the arc-shaped block 906, when the contact plate 701 is rotated, the support of the arc-shaped block 906 will not hinder the rotation angle, and through the support of the arc-shaped block 906, after the contact plate 701 is turned over, the arc-shaped block 906 will also give a forward thrust to the contact plate 701, thus ensuring the reset effect of the contact plate 701. One side of the arc-shaped block 906 close to the groove 902 is fixedly connected to a telescopic rod 903, and the side of the telescopic rod 903 away from the inclined block 905 is fixedly connected to the bottom of the groove 902 wall.

[0039] The working principle of this embodiment is as follows: When the contact plate 701 moves and flips and contacts the arc-shaped block 906, the arc-shaped block 906 is pushed by it to move towards the side close to the arc-shaped plate 5. Under the continuous push of the contact plate 701, the flipped panel can be irradiated and sterilized by the sterilization lamp 6. When the arc-shaped block 906 moves, it will press the third spring 904 to make it contract. After the contraction is completed, the third spring 904 rebounds to make the arc-shaped block 906 reset. The reset arc-shaped block 906 pushes the contact plate 701 to make the side of the contact plate 701 in contact with the arc-shaped block 906 return to the initial state. In this way, when the contact plate 701 rotates under the support of the corner of the arc-shaped block 906 after being turned over, there will be no angular deflection.
