Although this method has a simple structure, in actual use, when the voltmeter is hit, it will cause impact on the electronic devices inside the voltmeter, and then damage the electronic devices inside the voltmeter, resulting in poor protection effect. Therefore, it is necessary to design and modify the voltmeter for power detection to effectively prevent the phenomenon of poor protection effect. Utility Model Content

[0019] 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.

[0020] like Figures 1 to 4 As shown, a voltmeter for electric power detection comprises a base plate 1, a cylinder 3 is fixedly connected to the top of the base plate 1 on all sides, a piston rod 4 is movably connected to the inside of the cylinder 3, a support plate 5 is fixedly connected to the top of the piston rod 4, a square tube 2 is fixedly connected to the surface of the base plate 1, a frame 6 is fixedly connected to the top of the support plate 5, a buffer pad 7 is fixedly connected to the inner wall of the frame 6 on all sides, a voltmeter body 8 is movably connected to the top of the support plate 5, the voltmeter body 8 is movably connected to the buffer pad 7, a cover plate 17 is hinged on the top of the square tube 2, a fixing rod 9 is fixedly connected to both sides of the bottom of the support plate 5, a pulley 12 is fixedly connected to both sides of the top of the base plate 1 through a supporting column, a tension spring 10 is fixedly connected to both sides of the inner wall of the square tube 2, a disc 11 is fixedly connected to the surface of the tension spring 10, a pull rope 13 is fixedly connected to the surface of the fixing rod 9, the pull rope 13 is movably connected to the pulley 12, and the pull rope 13 is fixedly connected to the disc 11.

[0021] refer to Figure 1 and Figure 2 Lifting plates 16 are fixedly connected to both sides of the square tube 2.

[0022] As a technical optimization solution of the present invention, by providing the lifting plate 16, it is convenient for the operator to lift the device through the lifting plate 16, thereby improving the portability of the device.

[0023] refer to Figure 2 and Figure 3 The top of the bottom plate 1 is fixedly connected with copper tubes 14 all around, and the bottom plate 1 of the support plate 5 is fixedly connected with magnetic balls 15 all around through connecting rods, and the magnetic balls 15 are movably connected with the copper tubes 14.

[0024] As a technical optimization scheme of the utility model, through the arrangement of the copper tube 14 and the magnetic ball 15, when the magnetic ball 15 moves in the copper tube 14, countless closed loops can be seen in the copper tube 14. In the closed loop, if the number of magnetic flux lines passing through it changes, an induced current will be generated in the closed loop, and an opposite force will be generated between the induced current and the magnet, so that the induced current hinders the falling of the magnetic ball 15. Similarly, when the ball moves up in the copper tube 14, the copper tube 14 will also hinder the upward movement of the ball, thereby playing a damping role, avoiding the high-frequency up and down reciprocating motion of the support plate 5 due to the use of the tension spring 10 in the device, thereby achieving the purpose of shock absorption.

[0025] refer to Figure 2 and Figure 4 , the buffer pad 7 is made of silicone material.

[0026] As a technical optimization solution of the present invention, the buffer pad 7 made of silicone material has the advantages of high elasticity and corrosion resistance.

[0027] refer to Figure 1 and Figure 2 The cover plate 17 and the square tube 2 are movably connected via buckles.

[0028] As a technical optimization solution of the utility model, by movably connecting the cover plate 17 and the square tube 2 through a buckle, it is convenient for an operator to quickly open or close the cover plate 17, thereby making it convenient for the operator to use the voltmeter body 8.

[0029] refer to Figure 2 , the pull rope 13 is cut from a steel wire rope.

[0030] As a technical optimization solution of the utility model, the draw rope 13 cut from the steel wire rope has the advantages of high hardness and tensile resistance.

[0031] The working principle and use process of the utility model are as follows: during use, when the operator does not use the voltmeter body 8, the operator closes the cover 17, and the cover 17 and the square tube 2 can protect the voltmeter body 8 to prevent the voltmeter body 8 from being directly hit. When the square tube 2 is hit, the voltmeter body 8 will be shaken. When the voltmeter body 8 shakes in the vertical direction, it will drive the support plate 5 to move up and down. For example, when the support plate 5 moves down, it will drive the fixing rod 9 to move down, thereby pulling the pull rope 13. Under the guidance of the pulley 12, the pull rope 13 pulls the disc 11, thereby stretching the tension spring 10. According to the relationship between the action force and the reaction force, the tension spring 10 indirectly has an upward force on the support plate 5, thereby indirectly buffering the voltmeter body 8. At the same time, the downward movement of the support plate 5 will drive the piston rod 4 to move down, thereby compressing the gas in the cylinder 3, so that the air pressure in the cylinder 3 increases. At this time, the gas in the cylinder 3 indirectly has an upward force on the voltmeter body 8, thereby buffering the voltmeter body 8;

[0032] When the voltmeter body 8 shakes in the horizontal direction, it will be buffered by the buffer pad 7.
