Description

Technical Field

[0001] This utility model relates to the technical field of Young's modulus measuring instruments, specifically a multifunctional testing bracket for Young's modulus measuring instruments. Background Technology

[0002] A Young's modulus measuring instrument is an experimental device used to determine the Young's modulus (elastic modulus) of a material. Young's modulus is the ratio of stress to strain in a material during its elastic deformation phase, reflecting the material's resistance to elastic deformation. The measuring instrument calculates the Young's modulus by applying a controlled force or deformation and accurately measuring the corresponding deformation or force value. The components of the Young's modulus measuring instrument are supported by a corresponding support frame.

[0003] The existing technology has the following shortcomings: When adjusting the level of the current Young's modulus measuring instrument bracket, it is generally done by turning the leveling screw. During the adjustment process, the leveling screw needs to be turned frequently in different directions as needed. The adjustment process of the bracket is complicated and time-consuming. At the same time, the optical lever mounting platform is fixed to the bracket by tightening screws. Adjusting the position of the optical lever mounting platform requires repeatedly turning the tightening screws. Moreover, the tightening screws will wear and strip over time, affecting the stability of the optical lever mounting platform. Utility Model Content

[0013] Compared with the prior art, this utility model provides a multifunctional testing bracket for Young's modulus measuring instrument, which has the following beneficial effects:

[0014] 1. This multifunctional testing bracket for Young's modulus measuring instrument comprises a base, a rotating connector, a mounting plate, an electric telescopic rod, an integrated control device, a ball joint connector, and a rotating groove. The integrated control device controls the extension or retraction of the electric telescopic rod, causing the mounting plate to tilt towards the retracted electric telescopic rod. This controls the horizontal angle of the mounting plate relative to the base. The rotating connector ensures the flexibility and stability of the mounting plate adjustment process, preventing the mounting plate from shifting off the base. This achieves the effect of adjusting the overall bracket's horizontal angle. The operation is convenient, eliminating the need for frequent screw tightening and reducing the time spent on horizontal adjustment.

The limiting component and the limiting groove can form a limiting effect, fixing the position of the mounting platform on the vertical rods. The same applies to the fixing plate. By fixing the position of the mounting platform and the fixing plate through the limiting structure, premature wear can be avoided, ensuring the stability of the mounting platform and the fixing plate.

[0025] The stability of the connection between the placement platform 9 and the arc-shaped component 901 can be ensured by the magnet 903.

[0026] In this embodiment, the rotating connector 2 is specifically embedded in the rotating groove 14. The rotating connector 2 is adapted to the rotating groove 14. The mounting plate 3 is fixedly installed on the top of the rotating connector 2. There are six sets of electric telescopic rods 4 arranged in a ring at the bottom of the mounting plate 3. Each set of electric telescopic rods 4 has a set of ball head connectors 13 fixed at the output end and the bottom end. The bottom of the mounting plate 3 and the top of the base 1 are provided with circular grooves adapted to the ball head connectors 13. The ball head connectors 13 at the output end of the electric telescopic rod 4 are embedded in the bottom of the mounting plate 3, and the ball head connectors 13 at the bottom end of the electric telescopic rod 4 are embedded in the top of the base 1. The electric telescopic rod 4 is inclined.

[0027] Specifically, the horizontal angle of the mounting plate 3 relative to the base 1 can be flexibly controlled by the electric telescopic rod 4, and the ball joint connector 13 can ensure the flexibility of the connection between the electric telescopic rod 4 and the mounting plate 3 and the base 1.

[0028] In this embodiment, the integrated control device 5 is specifically composed of six independent control switches. The six independent control switches in the integrated control device 5 are electrically connected to the six sets of electric telescopic rods 4. The integrated control device 5 is electrically connected to an external power source. There are two sets of vertical rods 6. The mounting platform 9 and the fixing plate 8 are both mounted between the two sets of vertical rods 6. The arc-shaped part 901 is hinged to the mounting platform 9. A circular hole adapted to the vertical rod 6 is formed between the arc-shaped part 901 and the mounting platform 9. The limiting part 902 is specifically arc-shaped and fixedly installed in the arc-shaped part 901. The limiting part 902 is adapted to the limiting groove 15.

[0029] Specifically, the limiting member 902 can form a limiting effect with the limiting groove 15, ensuring the connection stability between the placement platform 9 and the fixing plate 8. The six independent control switches in the integrated control device 5 are the switches used in traditional small electric push rods.

[0030] In this embodiment, the side of the placement platform 9 is provided with a square groove that is compatible with the magnet 903. The placement platform 9 is made of iron. The two sides of the fixing plate 8 are provided with the same arc-shaped parts 901 as those on the placement platform 9 and have the same structure. The optical lever 10 is fixedly installed on the placement platform 9. The pressure sensor 11 is fixedly installed between the placement platform 9 and the fixing plate 8. One end of the steel wire 12 is fixedly connected to the bottom of the top plate 7, and the other end of the steel wire 12 passes through the placement platform 9 and is connected to the pressure sensor 11.

[0031] Specifically, the mounting plate 8 provides the installation conditions for the pressure sensor 11, and the mounting platform 9 facilitates the installation of the optical lever 10.

[0032] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the overall horizontal angle of the bracket during actual use, the electric telescopic rod 4 can be extended or retracted directly through the integrated control device 5. The mounting plate 3 will tilt towards the retracted electric telescopic rod 4, thereby controlling the horizontal angle of the mounting plate 3 relative to the base 1. During the process, rotating the connecting piece 2 can ensure the flexibility and stability of the mounting plate 3 adjustment process, preventing the mounting plate 3 from shifting off the base 1, thus achieving the effect of adjusting the overall horizontal angle of the bracket. The operation is convenient, does not require frequent tightening of screws, and reduces the time spent on the horizontal adjustment process of the bracket. When fixing the mounting platform 9 or the fixing plate 8, the following steps are taken: Taking the placement platform 9 as an example, the placement platform 9 is placed between the two sets of vertical rods 6, and the flipped arc-shaped part 901 is flipped so that the magnet 903 enters the corresponding square groove on the side of the placement platform 9 and forms a magnetic attraction between it and the placement platform 9. At this time, the limiting part 902 is in the limiting groove 15, which can limit the position of the placement platform 9 on the vertical rod 6, thereby achieving the effect of fixing the placement platform 9. Conversely, the position of the placement platform 9 can be adjusted at will by flipping the arc-shaped part 901. The position of the placement platform 9 is fixed by the limiting effect between the limiting part 902 and the limiting groove 15, which can prevent excessive wear and ensure the stability of the placement platform 9. The installation structure of the fixing plate 8 is the same as that of the placement platform 9.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
