Description

Technical Field

[0001] This utility model relates to the field of seated forward flexion measurement technology, and more specifically, to a seated forward flexion measurement device. Background Technology

[0002] In existing sit-and-reach measurement devices, the measuring rod, as the core component, is usually fixedly installed on the top of the support structure to facilitate the measurement of the degree of forward flexion. This design does provide stability and accuracy during measurement, but it has obvious shortcomings in the transportation and storage of the device.

[0003] Because the measuring rod extends outside the support structure and often lacks effective protective measures, it is highly susceptible to impacts during handling, moving, or storage, leading to bending, deformation, or even breakage of the measuring rod, which affects the service life and measurement accuracy of the device. Therefore, we have made improvements to address this issue and proposed a sit-and-reach measurement device. Utility Model Content

[0025] As attached Figures 1-4 As shown, this utility model includes a base 105 and a support rod 1 located above the base 105. Two protective parts 3 are provided on the base 105, and the top of each of the two protective parts 3 is provided with a first receiving groove 301. The protective parts 3 are made of foam, which has a good protective effect and its internal porous structure can effectively disperse and absorb external forces.

[0026] The top of the support rod 1 is provided with a sliding groove 101. Two measuring rods 2 are placed on the top of the support rod 1. One measuring rod 2 has a threaded groove 202 at its end, and the other measuring rod 2 has a threaded rod 201 fixedly connected to its end. The threaded rod 201 and the threaded groove 202 are threaded together. The threaded connection between the threaded rod 201 and the threaded groove 202 enables the measuring rod 2 to be detachable. This connection method is simple and reliable. It can ensure that the two measuring rods 2 are connected when in use to form a complete measuring rod, and can also be easily separated when storage or transportation is required. Since the overall length is shortened after separation, it is easier to store and transport. The measuring rod 2 is provided with a scale.

[0027] Both measuring rods 2 have slots 205 at their bottoms. Slides 101 are connected to adjusting components. The adjusting components have two claws 103. The two claws 103 are inserted into the inner walls of the two slots 205 respectively. The measuring rods 2 can be fixed by inserting the claws 103 into the slots 205.

[0028] Furthermore, a slide block 203 is slidably connected between the outer surfaces of the two measuring rods 2, and a push plate 204 is fixedly connected to the slide block 203. The slide block 203 and the outer surface of the measuring rod 2 are slidably connected. This connection method has good smoothness and stability. The push plate 204 is fixed on the slide block 203. When the user pushes the push plate 204 with their finger, the force can be directly transmitted to the slide block 203, so that it slides smoothly along the measuring rod 2 for measurement.

[0029] Furthermore, the adjusting component includes a bidirectional screw 102 mounted in the slide groove 101 via a bearing, and two claws 103 are threadedly connected to the outer surface of the bidirectional screw 102. During rotation, the bidirectional screw 102 can drive the two claws 103 to move closer or further apart to achieve connection and separation between the claws 103 and the slot 205.

[0030] Furthermore, one end of the bidirectional screw 102 extends from the side of the support rod 1 to the outside of the support rod 1 and is fixedly connected to a handwheel, which facilitates the rotation of the bidirectional screw 102.

[0031] Furthermore, a support plate 104 is fixedly connected to the bottom of the support rod 1. The bottom of the support plate 104 is fixedly connected to the top of the base 105. The support plate 104 is used to cooperate with the base 105 to support the support rod 1.

[0032] Furthermore, a reinforcing plate 106 is fixedly connected to the side of the support plate 104, and the reinforcing plate 106 is fixedly connected to the top of the support plate 104. The reinforcing plate 106 can reinforce the connection between the support plate 104 and the base 105, thereby improving the stability of the structure.

[0033] Furthermore, a suspension groove 107 is provided on the support plate 104, and an auxiliary component is connected to the support plate 104 through the suspension groove 107.

[0034] Furthermore, the auxiliary component includes a foot pedal 4 disposed on the side of the support plate 104 away from the protective component 3. The side of the foot pedal 4 near the support plate 104 is provided with a hook 401, and the hook 401 is suspended on the side wall of the suspension groove 107. The side of the foot pedal 4 away from the support plate 104 is used for placing the sole of the foot of the person being tested during use. The foot pedal 4 is suspended by the hook 401 and the suspension groove 107, making it easy to remove for cleaning.

[0035] Furthermore, each of the two first receiving slots 301 is provided with a pick-up and put-down slot 302 on both sides. The pick-up and put-down slot 302 is used to assist in picking up and putting down the measuring rod 2. The pick-up and put-down slot 302 is designed to provide operating space for the fingers so as to facilitate picking up and putting down the measuring rod 2.

[0036] Furthermore, a second receiving groove 303 and a third receiving groove 304 are provided on the side wall of one of the first receiving grooves 301. The second receiving groove 303 is used to store the threaded rod 201, and the third receiving groove 304 is used to store the slide 203 and the push plate 204, so that the threaded rod 201, the slide 203 and the push plate 204 can also be protected.

[0037] When transshipment or storage is required, refer to Figure 1Rotating the handwheel causes the bidirectional screw 102 to rotate, so that the two pawls 103 move away from each other. Pulling the measuring rod 2 upwards removes the measuring rod 2 from the top of the support rod 1. Pushing the slide 203 onto the measuring rod 2 with the threaded rod 201, rotating either measuring rod 2 causes the threaded groove 202 to separate from the threaded rod 201. Then, the two measuring rods 2 are placed into the two first receiving slots 301, and the measuring rod 2 with the threaded rod 201 is placed into the first receiving slot 301 with the second receiving slot 303. The slide 203 and the push plate 204 are placed into the third receiving slot 304, as shown in Figure 5. At this time, the measuring rod 2 is protected by the protective part 3, and the support rod 1 can be used as a handle to facilitate lifting and moving the application, thereby improving the functionality of the support rod 1.

[0038] Refer to when needed. Figure 5 After removing the measuring rod 2, connect the threaded rod 201 to the threaded groove 202. Align the slot 205 with the jaw 103 and insert it. Rotate the handwheel to bring the two jaws 103 closer together and engage with the inner wall of the slot 205 to form a limit position. Figure 1 As shown.
