DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A sitting forward flexion tester, comprising:

[0026] The main body comprises a bottom plate 1, a vertical plate 11 is fixedly connected to the surface of the bottom plate 1, a measuring track 12 is fixedly connected to the surface of the vertical plate 11, a first slider 13 is slidably connected to the surface of the measuring track 12, and a push plate 14 is fixedly connected to the surface of the first slider 13;

[0027] The observation mechanism includes a guide rod 2, which is fixedly connected to the lower surface of the first slider 13, a spring 21 is fixedly connected to the lower surface of the guide rod 2, a movable rod 22 is fixedly connected to the bottom of the spring 21, a foot pedal 23 is fixedly connected to the bottom of the movable rod 22, a vertical rod 24 is fixedly connected to the surface of the base plate 1, an observation guide rail 25 is fixedly connected to the top of the vertical rod 24, a second slider 26 is fixedly connected to the surface of the observation guide rail 25, and a limiting rod 27 is fixedly connected to the surface of the second slider 26. The observation mechanism can observe the tester's results at a higher position without the need for the tester to bend down to check, thereby reducing the test burden of the tester.

[0028] Furthermore, a protective mechanism is provided on the surface of the vertical board 11, and the protective mechanism includes a through hole 3, which is opened on the surface of the vertical board 11. The surface of the vertical board 11 is perforated with a limit rope 31, and the surface of the limit rope 31 is fixedly connected with a protective cloth 32. During the sit-and-reach test, different testing methods will be adopted. Some testing processes require the tester to take off shoes, while some tests do not require the tester to take off shoes. In order to avoid dirtying the vertical board 11 during the test without taking off shoes, the protective mechanism provided on the vertical board 11 can facilitate the cleaning of the surface of the vertical board 11, thereby improving the practicability of the equipment.

[0029] Furthermore, a guide groove is provided at the bottom of the guide rod 2, and a spring 21 is fixedly connected to the guide groove of the guide rod 2. The movable rod 22 slides on the guide groove of the guide rod 2, and the movable rod 22 drives the foot pedal 23 to slide at the bottom of the guide rod 2. The tester can step on the foot pedal 23 so that the foot pedal 23 is abutted against the surface of the base plate 1. At this time, the position of the foot pedal 23 is limited by the tester's foot. The foot pedal 23 limits the position of the first slider 13 through the movable rod 22 and the guide rod 2, so that the first slider 13 cannot slide on the measuring track 12. When the measuring personnel releases his foot, the elastic force of the spring 21 will pull the movable rod 22 and the foot pedal 23 back to their original position.

[0030] Furthermore, the limit rod 27 slides on the surface of the observation guide rail 25 through the second slider 26. The horizontal height of the observation guide rail 25 is higher than the horizontal height of the measuring track 12. The observation guide rail 25 and the measuring track 12 are parallel to each other. The observation guide rail 25 is in an area that the observer can observe without bending over.

[0031] Furthermore, the bottom of the limit rod 27 and the push plate 14 are on the same horizontal plane, and the limit rod 27 can slide on the observation guide rail 25 until it is abutted against the surface of the push plate 14. The foot pedal 23 can limit the position of the first slider 13, thereby limiting the position of the push plate 14. At this time, the limit rod 27 can no longer move toward the push plate 14, and the reading value of the second slider 26 on the observation guide rail 25 is the same as the reading value of the first slider 13 on the measurement track 12, which avoids the measurement personnel from bending over to view the value on the measurement track 12.

[0032] Furthermore, four groups of through holes 3 are provided, and the limiting ropes 31 are connected to the surface of the vertical plate 11 through the through holes 3. The limiting ropes 31 limit the position of the protective cloth 32 on the vertical plate 11, thereby facilitating the position of the protective cloth 32.

[0033] Furthermore, four groups of limiting ropes 31 are provided, and the limiting ropes 31 correspond to the through holes 3. The protective cloth 32 is attached to the surface of the vertical board 11, and the four groups of limiting ropes 31 are knotted in pairs, so that the protective cloth 32 covers one side of the vertical board 11 on the surface of the vertical board 11.

[0034] Working principle: When the tester pushes the push plate 14 to complete the test, the tester steps on the foot pedal 23, so that the foot pedal 23 is connected to the surface of the base plate 1. The foot pedal 23 is restricted on the surface of the base plate 1 by the tester's foot. The foot pedal 23 limits the position of the first slider 13 and the push plate 14 on the measuring track 12 through the guide rod 2 and the movable rod 22. At this time, the second slider 26 is slid on the surface of the observation guide rail 25, so that the second slider 26 drives the limit rod 27 to be connected to the surface of the push plate 14. At this time, the position of the first slider 13 on the measuring track 12 can be known through the position of the observation guide rail 25 where the second slider 26 is located, thereby obtaining the sliding distance of the push plate 14 on the measuring track 12. The tester does not need to bend down to view the data, which reduces the burden on the tester.

[0035] The vertical plate 11 is connected through the through hole 3 and the four groups of limiting ropes 31, and the protective cloth 32 is attached to the surface of the base plate 1. The four groups of limiting ropes 31 are then knotted and fixed on the side of the vertical plate 11 away from the protective cloth 32, so that the protective cloth 32 is firmly installed on the surface of the vertical plate 11, preventing the vertical plate 11 from being dirty by the testers, facilitating the cleaning of the equipment, and improving the practicability of the equipment.
