[0002] A pressure calibrator is a high-precision measuring instrument that uses multiple CPUs for auxiliary processing to ensure the high precision and reliability of the results. A pressure gauge calibrator is an indispensable device for repairing and calibrating pressure gauges. It can be used for calibrating pressure measuring instruments, calibrating non-pressure measuring instruments with a certain functional relationship with pressure values, and can also be used for pressure-bearing experiments of pressure vessels.

[0003] Since there are many precision electronic components inside the pressure calibrator, the pressure calibrator is usually fixed inside the protective shell for protection, which makes it not easy to disassemble the pressure calibrator from the protective shell, reducing the efficiency of maintenance and repair. At the same time, the pressure calibrator is prone to falling due to unstable placement or accidental human touch during daily use, which reduces the service life of the pressure calibrator.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1-5 , the present utility model provides a technical solution: an installation structure of a pressure calibrator, including a protective shell 1, the side surface of the protective shell 1 is fixedly welded to the side surface of the protective plate 2, two symmetrical first buffer springs 3 are fixedly welded to the inner bottom surface of the protective shell 1, one end of the first buffer spring 3 is fixedly welded to the bottom surface of the pressing plate 4, several symmetrical second buffer springs 5 are fixedly welded to both sides of the protective shell 1, one end of the second buffer spring 5 is fixedly connected to the side surface of the side plate 6, two symmetrical first buffer blocks 7 are adhesively connected to the inside of the protective shell 1, symmetrical card slots 8 are opened on both sides of the protective shell 1, the card slots 8 are movably inserted with the buckles 14, the pressure calibrator 9 is movably inserted into the inside of the protective shell 1, the top of the protective shell 1 is movably clamped with the cover plate 10 through the card slots 8 and the buckles 14, two symmetrical sliding grooves 11 are opened on the top of the cover plate 10, the sliding grooves 11 are slidably connected with the pushing plate 15, both ends of two rotating shafts 12 are rotatably connected to the inside of the cover plate 10, the outside of the rotating shaft 12 is fixedly welded to the connecting plate 13, one end of the connecting plate 13 is fixedly welded to the top of the buckle 14, the other end of the connecting plate 13 is fixedly welded to the pushing plate 15, two symmetrical fixing springs 16 are fixedly connected to the inside of the cover plate 10, the fixing springs 16 are located between the cover plate 10 and the connecting plate 13, and two symmetrical second buffer blocks 17 are adhesively connected to the lower surface inside the cover plate 10.

[0023] The bottom of the protective shell 1 is provided with rounded corners. The outer diameter dimensions of the protective shell 1 and the protective plate 2 are the same. The shape of the protective plate 2 is U-shaped, and the protective plate 2 is provided with rounded corners. The pressure calibrator 9 is prevented from detaching from the side of the protective plate 2 while being movably inserted into the protective shell 1 through the settings of the protective shell 1 and the protective plate 2. The U-shaped setting of the protective plate 2 facilitates the operation of the buttons on the pressure calibrator 9 and also facilitates the viewing of the display screen on the pressure calibrator 9. The first buffer block 7 and the sliding groove 11 are both made of rubber material. The first buffer block 7 is provided with an arc groove. The first buffer block 7 is located on both sides of the bottom of the protective shell 1. The rubber material can buffer and absorb the impact force when the pressure calibrator 9 drops, avoiding damage to the internal components of the pressure calibrator 9. The shape of the card slot 8 is rectangular, and the inner diameter dimension of the card slot 8 is adapted to the outer diameter dimension of the buckle 14. The buckle 14 is movably clamped with the card slot 8. The buckle 14 has a certain elasticity, and the buckle 14 is provided with a chamfer. The clamping of the buckle 14 and the card slot 8 facilitates the disassembly of the cover plate 10 and the protective shell 1. At the same time, the chamfer provided on the buckle 14 facilitates the movement of the buckle 14 on the side of the protective shell 1 and also facilitates the clamping inside the buckle 14. The pressure calibrator 9 is provided with a display screen and several buttons. A connection socket is provided at the top of the pressure calibrator 9. A rectangular through groove is provided at the top of the cover plate 10. The connection socket at the top of the pressure calibrator 9 and the rectangular through groove at the top of the cover plate 10 have the same size and corresponding positions. The shapes of the sliding groove 11 and the push plate 15 are both rectangular. The inner diameter dimension of the sliding groove 11 is adapted to the outer diameter dimension of the push plate 15. The push plate 15 is slidably connected with the sliding groove 11. One end of the fixed spring 16 is fixedly connected to the upper part of the rotating shaft 12. The fixed spring 16 is located between the inner wall of the cover plate 10 and the side of the connecting plate 13. In this way, the elastic force of the fixed spring 16 can be used to squeeze the connecting plate 13 and fix the buckle 14 in the card slot 8, preventing the buckle 14 from detaching from the card slot 8.

[0024] Working principle: When in use, the operator inserts the instrument to be measured through a wire through the rectangular through-hole at the top of the cover plate 10 into the connection socket at the top of the pressure calibrator 9, and then performs detection through the buttons on the surface of the pressure calibrator 9 and views the results using the display screen on the pressure calibrator 9; when the pressure calibrator 9 accidentally falls, the pressure calibrator 9 will squeeze the pressing plate 4 at the bottom and squeeze the side plates 6 on both sides, further compressing the first buffer spring 3 and the second buffer spring 5 for buffering. At the same time, it cooperates with the first buffer block 7 at the bottom of the protective shell 1 and the two second buffer blocks 17 on the cover plate 10 to buffer and shock-absorb the pressure calibrator 9, effectively avoiding the situation where the internal components of the pressure calibrator 9 are damaged due to accidental falling; when it is necessary to disassemble and assemble the pressure calibrator 9, push the two push plates 15 to move outward in the sliding grooves 11 at the same time, and then the connecting plate 13 will rotate under the cooperation of the rotating shaft 12, further causing the buckle 14 to disengage from the card slot 8, and then move the push plate 15 upward. The pressure calibrator 9 will pop out under the elastic force of the first buffer spring 3 at the bottom of the protective shell 1, and the pressure calibrator 9 can be taken out. If it is necessary to place the pressure calibrator 9 inside the protective shell 1, insert the bottom of the pressure calibrator 9 between the protective shell 1 and the protective plate 2, and make the bottom of the pressure calibrator 9 squeeze the pressing plate 4 and the side of the pressure calibrator 9 squeeze the side plate 6. Then insert the buckles 14 on both sides of the cover plate 10 into the protective shell 1 and move them downward until the buckles 14 on both sides are inserted into the card slot 8 to fix the cover plate 10 and the protective shell 1. At the same time, use the second buffer block 17 to fix the pressure calibrator 9 inside the protective shell 1. At this time, under the elastic force of the fixing spring 16, the connecting plate 13 is squeezed to make the buckle 14 fixed in the card slot 8, preventing the cover plate 10 and the pressure calibrator 9 from popping out under the action of the first buffer spring 3.
