Description

Technical Field

[0001] The utility model relates to the field of frequency display instruments, and more specifically, to a frequency display instrument for an electric power system. Background Art

[0002] The frequency display instrument is a test instrument widely used in power systems. It is used to detect the frequency of relevant data in the power system, so as to facilitate technicians to inspect and test whether the relevant data in the power system is normal.

[0003] The frequency display instrument should be used in an environment that avoids corrosive gases, dust, unstable vibration and impact forces, etc. The unstable vibration and impact forces from the outside world are difficult to be completely isolated, especially in some special areas outside. The structure of the traditional frequency display instrument is relatively simple. When used in some scenes such as mountains and roads in open-air environments, the inclination of the road surface and vibration conduction are difficult to isolate in advance. These unstable external vibration forces are prone to tipping over when encountering an inclined support surface. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a frequency display instrument for an electric power system, which can realize the movement of the threaded shaft up and down in the threaded groove by rotating the corresponding threaded shaft, thereby compensating for the height difference of a corner of the instrument on the uneven supporting surface and improving the stability of the instrument. At the same time, the electromagnet located in the threaded shaft can also be started, so that the electromagnet generates a magnetic attraction to the magnetic block, attracting the magnetic block to approach the electromagnet. During this process, the magnetic block will pull the lifting block to move synchronously and squeeze the spring to cause compression deformation. The lifting block will press down the four connecting blocks, and the four connecting blocks will push the four arc-shaped support blocks to expand outward, ultimately expanding the support area between one end of the threaded shaft and the supporting surface, thereby further improving the stability of the instrument during use. At the same time, the setting of the spring will also enhance the shock-absorbing effect at the arc-shaped support block. After use, you only need to turn off the electromagnet. Under the elastic force of the spring, the arc-shaped support block, the connecting block and the lifting block are reset for easy storage.

[0006] 2. Technical solution

By setting the four support assemblies 5, it can be achieved that the lifting block 9 is not moved in some open-air environments. When the instrument is used on a flat support surface, first, rotate the corresponding threaded shaft 6 so that the threaded shaft 6 moves up and down in the threaded groove, thereby compensating for the height difference of a corner of the instrument on the uneven support surface and improving the stability of the instrument. At the same time, the electromagnet 12 located in the threaded shaft 6 can also be started, so that the electromagnet 12 generates a magnetic attraction to the magnetic block 14, attracting the magnetic block 14 to approach the electromagnet 12. During this process, the magnetic block 14 will pull the lifting block 9 to move synchronously and squeeze the spring 13 to cause compression deformation. The lifting block 9 will press down the four connecting blocks 8, and the four connecting blocks 8 will push the four arc-shaped support blocks 7 to expand outward, ultimately achieving the expansion of the support area between one end of the threaded shaft 6 and the support surface, thereby further improving the stability of the instrument during use. At the same time, the setting of the spring 13 will also enhance the shock-absorbing effect at the arc-shaped support block 7. After use, you only need to turn off the electromagnet 12. Under the elastic force of the spring 13, the arc-shaped support block 7, the connecting block 8 and the lifting block 9 are reset for easy storage.

[0028] A stopper 10 is fixedly connected to one end of the lifting block 9 opposite to the threaded shaft 6, and a rubber ring 11 is sleeved and fixed on the arc-shaped outer wall of the stopper 10. The arc-shaped outer wall of the rubber ring 11 is fit-connected with the inner walls of the four arc-shaped support blocks 7. By setting the stopper 10 and the rubber ring 11, the gaps between the four arc-shaped support blocks 7 can be closed to prevent foreign matter or water from entering the support assembly 5 and causing damage to parts.

[0029] The four arc-shaped support blocks 7 are arranged on one side opposite to the threaded shaft 6 as an inclined surface, and the inclined surface is fixedly connected with an anti-skid pad 15. By setting one end of the arc-shaped support block 7 as an inclined surface, the stability between the arc-shaped support block 7 and the supporting surface can be improved after the arc-shaped support block 7 is deflected. At the same time, the setting of the anti-skid pad 15 can also enhance the shock-absorbing and anti-skid effect at the arc-shaped support block 7.

[0030] The eight corners of the instrument body 1 are all embedded with anti-collision covers 4, and the anti-collision covers 4 are made of highly wear-resistant elastic material. By embedding the anti-collision covers 4 made of elastic material on the eight corners of the instrument body 1, the effect of preventing sharp edges from accidentally injuring people or causing damage to the instrument due to collision during the movement and transportation of the instrument can be achieved.

[0031] A winding rack 3 is fixedly connected to one side of the instrument body 1, and a slot for clamping the power cord is opened on one side of the winding rack 3. Through the setting of the winding rack 3, it is convenient for technicians to wind the power cord on the winding rack 3, and finally clamp the power cord at the power cord plug into the slot, thereby achieving the effect of storing and fixing the wound power cord, which is convenient for technicians to move and store.

[0033] Working principle: When the device is in use, first, rotate the corresponding threaded shaft 6 so that the threaded shaft 6 moves up and down in the threaded groove, thereby compensating for the height difference of a corner of the instrument on the uneven supporting surface and improving the stability of the instrument. At the same time, the electromagnet 12 located in the threaded shaft 6 can also be started, so that the electromagnet 12 generates a magnetic attraction to the magnetic block 14, attracting the magnetic block 14 to approach the electromagnet 12. In this process, the magnetic block 14 will pull the lifting block 9 to move synchronously and squeeze the spring 13 to cause compression deformation. The lifting block 9 will press down the four connecting blocks 8, and the four connecting blocks 8 will push the four arc-shaped support blocks 7 to expand outward, and finally expand the support area between one end of the threaded shaft 6 and the supporting surface, thereby further improving the stability of the instrument when in use. At the same time, the setting of the spring 13 will also enhance the shock-absorbing effect of the arc-shaped support block 7. After use, you only need to turn off the electromagnet 12. Under the elastic force of the spring 13, the arc-shaped support block 7, the connecting block 8 and the lifting block 9 are reset for easy storage.

[0034] It is worth noting that by setting one end of the arc-shaped support block 7 as an inclined surface, the stability between the arc-shaped support block 7 and the support surface can be improved after the arc-shaped support block 7 is deflected. At the same time, the setting of the anti-slip pad 15 can also enhance the shock-absorbing and anti-slip effect at the arc-shaped support block 7.
