Description

Technical Field

[0001] This utility model relates to the technical field of flexibility testing devices, specifically a convenient adjustment base for a seated forward flexion testing terminal. Background Technology

[0002] The sit-and-reach test is a physical fitness test item for primary, secondary, and tertiary schools. Its purpose is to measure the range of motion that the trunk, waist, hip, and other joints can achieve in a static state. It mainly reflects the extensibility and elasticity of the joints, ligaments, and muscles in these areas, as well as the development level of the body's flexibility.

[0003] The "A Base Plate Splicing Type Seated Forward Bending Device" disclosed in application number "CN201921875947.1" "includes a base plate, on which a test platform is provided. The test platform includes a support plate perpendicular to the base plate for the subject's feet to rest against, and a measuring guide rail parallel to the base plate and mounted on the support plate. A hand-push device that can move along the length of the measuring guide rail is provided on the measuring guide rail. The base includes a seat plate and a support plate. A splicing block is provided between the seat plate and the support plate. The seat plate and the support plate are detachably spliced ​​together by the splicing block." In this utility model, when not in use, the seat plate and the support plate can be separated, and the support plate can be folded and placed on the seat plate, reducing the horizontal footprint of the base plate and improving the vertical space utilization. It is convenient to store in a corner of the room, and the splicing detachable connection method makes it easy to disassemble and assemble. When needed, it can be reassembled.

[0004] However, the above method still has the following drawbacks: by using splicing blocks to splice the seat and support plate separately, the splicing blocks are always locked together with the seat and support plate. Due to different usage requirements, they need to be moved multiple times. During the movement, the three are prone to separation. This means that the splicing blocks need to be used to splice the seat and support plate multiple times, which may require additional operations. Utility Model Content

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This convenient adjustable base for the sit-and-reach test terminal, through a fixing block in the plug-in assembly, and a movable plug-in rod, in conjunction with a support plate and spring, allows the plug-in rod and protrusion to retract along the plug-in hole into the moving groove, making the rotation of the second base unrestricted. Combined with the rotatably connected support block and the second base, it facilitates folding and adjustment of the second base. With the help of a magnet and iron plate, the two are magnetically fixed together, reducing space occupation and improving space utilization. The extension and retraction of the plug-in rod and protrusion serve to limit, fix, and separate the second base, facilitating movement or folding adjustment between the first and second bases. This prevents separation of the first and second bases during movement and reduces the need for additional operations to fold and limit the use of the first and second bases at the bottom of the sit-and-reach test platform.

[0016] 2. The convenient adjustable base for the sit-and-reach test terminal uses a U-shaped pull rod in the fixed assembly to move two plug-in long rods, which in turn moves the rotating seat and the top plate on the surface. The mutual abutment between the top plate and the groove facilitates the limiting operation of the plug-in long rods, thereby enabling the second base to be folded without requiring the tester to stretch the U-shaped pull rod for a long time, saving time and effort and making it more convenient to use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a convenient adjustable base for a seated forward flexion test terminal, including a first base 1. The top of the first base 1 is provided with a forward flexion test platform 5, which facilitates forward flexion testing. A rectangular groove 2 is provided on one side of the first base 1, and a support block 3 is rotatably connected inside the rectangular groove 2. A second base 4 is provided on one side of the support block 3. The first base 1 and the second base 4 are rotatably connected, which facilitates the folding and use of the second base 4, reduces the space occupied, facilitates the adjustment of the second base 4, and facilitates the overall movement of the first base 1, the second base 4, and the forward flexion test platform 5, making it more convenient to use. Movable grooves 6 are provided on both sides of the first base 1, and plug-in components 7 are provided inside the movable grooves 6. The plug-in components 7 provide a limiting function for the rotatably connected second base 4. A fixing component 8 is provided on the other side of the first base 1, which provides a limiting function for the plug-in long rod 702.

[0025] The plug-in assembly 7 includes a support block 701, which is fixedly installed inside the movable groove 6. A plug-in rod 702 is slidably connected inside the support block 701. One end of the plug-in rod 702 is provided with a protrusion 703. The second base 4 has a plug-in hole that matches the plug-in rod 702. By placing the first base 1 and the second base 4 on a horizontal plane, the plug-in rod 702 and the protrusion 703 cooperate with the plug-in hole to limit the rotation of the second base 4, making it easier to move the first base 1 and the second base 4 as a whole, and reducing the need for additional operations to move the first base 1 and the second base 4.

[0026] The other end of the plug-in long rod 702 passes through the first base 1 and is fixedly connected to both ends of the U-shaped pull rod 801. The first base 1 has a through hole that matches the plug-in long rod 702, which makes it easier to move the two plug-in long rods 702 inside the moving slot 6 by the U-shaped pull rod 801. This makes it more convenient to use. The through hole in the first base 1 allows the plug-in long rod 702 to be moved without any restriction, making it easy to move.

[0027] A spring 704 is fitted on the surface of the insertion rod 702, and a support plate 705 is provided on the surface of the insertion rod 702. One end of the spring 704 is fixedly connected to one side of the support plate 705, and the other end of the spring 704 is fixedly connected to one side of the support block 701. By providing the spring 704 at the insertion rod 702 and between the corresponding support block 701 and the support plate 705, the insertion rod 702 can be limited and supported.

[0028] A magnetic plate 9 is embedded on one side of the bottom end of the first base 1, and an iron block 10 is embedded on one side of the bottom end of the second base 4. The magnetic plate 9 and the iron block 10 are magnetically connected. By setting the magnetic plate 9 and the iron block 10 at the first base 1 and the second base 4, it is easier for the two to be magnetically connected to each other during the folding process of the second base 4. The two are fixed and the transportation is more convenient.

[0029] The top of the forward flexion test platform 5 is provided with a handle 11, and the surface of the handle 11 is provided with an anti-slip sleeve. The surface of the rotating seat 802 is provided with a handle 805, which makes it easier to lift and move the forward flexion test platform 5, the first base 1 and the second base 4 through the handle 11, making it more convenient to use.

[0030] The fixing component 8 includes a U-shaped pull rod 801, which is located on the other side of the first base 1. A rotating seat 802 is rotatably connected to the surface of the U-shaped pull rod 801. A top plate 803 is provided on one side of the rotating seat 802. A groove 804 corresponding to the top plate 803 is opened inside the first base 1. The U-shaped pull rod 801 facilitates the simultaneous stretching and movement of the two plug-in long rods 702. Rotating the rotating seat 802 causes the top plate 803 on the surface of the rotating seat 802 to rotate, so that the top plate 803 is inserted into the groove 804. This facilitates the positional limitation of the top plate 803, the U-shaped pull rod 801, and the two plug-in long rods 702, making it convenient to rotate and adjust the second base 4 and freeing the hand from pulling the U-shaped pull rod 801.

[0031] The two corners of the surface of the forward flexion test platform 5 are provided with L-shaped mounting plates 12. The surface of the L-shaped mounting plates 12 is provided with two bolts 13. The surface of the first base 1 is provided with screw holes that match the bolts 13. By providing L-shaped mounting plates 12 and corresponding mounting holes at the diagonal corners of the surface of the forward flexion test platform 5, it is easy to disassemble the bolts 13, making it convenient to disassemble or inspect and maintain the forward flexion test platform 5.

[0032] The surface of the forward flexion test platform 5 is embedded with a support plate 16, which is made of rubber. By embedding the support plate 16 on the surface of the forward flexion test platform 5, it is convenient for the feet of the tester to be supported. At the same time, the material is rubber, which has good anti-slip and wear-resistant properties, making it convenient for forward flexion testing, and also convenient for protecting the paint surface of the forward flexion test platform 5.

[0033] A first rubber pad 14 is embedded on the surface of the first base 1, and a second rubber pad 15 is embedded on the surface of the second base 4. The first rubber pad 14 and the second rubber pad 15 provided at the first base 1 and the second base 4 can improve the comfort of the tester during the test and make it more convenient for the tester to use.

[0034] In use, the forward flexion test platform 5 is first placed at the test location. A seated forward flexion test is then performed using the forward flexion test platform 5, the first base 1, and the second base 4. After the test, when it is necessary to move the forward flexion test platform 5, the first base 1, and the second base 4, the provided connecting rods 702 can limit the movement of the first base 1 and the second base 4, allowing for direct movement of the forward flexion test platform 5, the first base 1, and the second base 4, reducing additional operations. When it is necessary to fold the second base 4, the handle 805 moves the rotating seat 802, which in turn moves the U-shaped pull rod 801, causing the two connecting rods 702 to move, thus allowing the connecting rods to fold. The long rod 702 retracts into the moving slot 6 and drives the top plate 803 at the rotating seat 802 to rotate, so that the top plate 803 and the groove 804 correspond to each other. Then, the handle 805 is released, so that the top plate 803 and the groove 804 abut and limit, thereby limiting the two plug-in long rods 702. At this time, the plug-in long rods 702 are separated from the plug-in holes. With the rotating support block 3, the second base 4 can be folded for use. With the magnetic plate 9 and the iron block 10, the two can be magnetically fixed together, reducing the space occupied and improving the space utilization. Finally, with the handle 11, the forward flexion test platform 5, the first base 1 and the second base 4 can be moved to the appropriate position.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
