[0021] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0022] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] like Figures 1 to 6 As shown, a vibration-proof display instrument comprises a protective shell 1 and an instrument body 2. The instrument body 2 is located inside the protective shell 1. The upper end of the instrument body 2 is clamped with a transparent cover plate 3. Plug holes 4 are provided at both ends of the transparent cover plate 3. The plug holes 4 are used in conjunction with a fixing structure 5. The fixing structure 5 is fixedly installed on both sides of the upper end of the protective shell 1 to facilitate the installation and disassembly of the transparent cover plate 3 and to inspect the inside of the instrument body 2. The fixing structure 5 comprises a fixing plate 15. A slidable plug rod 16 is installed inside the fixing plate 15. The plug rod 16 is located inside the fixing plate 15 and a pressure plate 18 is fixedly installed at one end thereof. A spring 17 is installed on the surface of the plug rod 16. When the plug rod 16 moves, the pressure plate 18 can compress the spring 17. One end of the plug rod 16 is plugged into the plug hole 4. Under the action of the spring 17, the plug rod 16 is inserted into the plug hole 4 to fix the transparent cover plate 3. A pull ring 19 is installed on the other end of the plug rod 16. The pull ring 19 is used to facilitate pulling the plug rod 16 so that the plug rod 16 is separated from the plug hole 4, thereby removing the transparent cover plate 3.

[0025] The two ends of the protective shell 1 are connected to the vibration reduction structure 6, which includes a vertical rod 9. A spring 10 is mounted on the surface of the vertical rod 9. The spring 10 is located in the middle of the vertical rod 9. Slide blocks 11 are fixedly installed at the upper and lower ends of the spring 10. The two slide blocks 11 are mounted on the surface of the vertical rod 9 and can slide. Damping springs 14 are installed at the other ends of the two slide blocks 11. When the slide blocks 11 slide on the surface of the vertical rod 9, the spring 10 is compressed or stretched. The damping spring 14 can slow down the vibration of the spring 10. The slider 11 is hingedly installed at one end close to the instrument body 2, and the other end of the connecting rod 12 is hingedly installed at the side plate 13. The upper end of the side plate 13 is a smooth inclined surface, which is convenient for placing the instrument body 2 in the protective shell 1. The two side plates 13 are in contact with the instrument body 2. When the instrument body 2 is hit and vibrates, the vibration is transmitted through the side plates 13, thereby driving the connecting rod 12 to rotate, and the other end of the connecting rod 12 drives the slider 11 to move, thereby driving the spring 10 to stretch or compress. The damping spring 14 can slow down the vibration of the spring 10 and protect the instrument body 2.

[0026] Positioning rods 7 are fixedly installed on both sides of the lower end of the instrument body 2, and positioning grooves 20 are fixedly installed on both sides of the bottom end of the protective shell 1. The positioning rods 7 are inserted into the positioning grooves 20 to fix the position of the instrument body 2. The lower end of the positioning rods 7 is threadedly connected to the bolts 8. The bolts 8 are located in the through grooves opened at the bottom of the protective shell 1 to fix the positioning rods 7. A sealing gasket 21 is inserted into the through groove. The sealing gasket 21 is in contact with the bottom of the bolts 8 to protect the bolts 8.

[0027] Connecting plates 22 are installed at both ends of the outside of the protective shell 1 , and threaded holes 23 are provided inside the connecting plates 22 . The protective shell 1 can be installed at the position where the instrument body 2 is needed through the connecting plates 22 and the threaded holes 23 .

[0028] During specific use, the instrument body 2 is placed into the protective shell 1, the positioning rod 7 is inserted into the positioning groove 20, the positioning rod 7 is fixed with the bolt 8, and the protective shell 1 is installed and fixed through the connecting plate 22 and the threaded hole 23. When the protective shell 1 is hit, the instrument body 2 transmits the vibration to the side plate 13, and the side plate 13 vibrates to drive the connecting rod 12 to rotate. The other end of the connecting rod 12 drives the slider 11 to move, thereby driving the spring 10 to stretch or compress. The damping spring 14 can slow down the vibration of the spring 10 and protect the instrument body 2.

[0029] When it is necessary to remove the transparent dial 3, pull the pull ring 19 to drive the insertion rod 16 out of the socket, and the pressure plate 18 compresses the spring 2 17, so that the transparent dial 3 can be removed and the instrument body 2 can be inspected. After the inspection is completed, pull the pull ring 19 again to insert the transparent dial 3 into the instrument body 2, release the pull ring 19, and the elastic potential energy of the spring 2 17 drives the pressure plate 18 to move, thereby driving the insertion rod 16 to insert into the socket 4 to fix the transparent dial 3.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
