Description

Technical Field

[0001] The utility model relates to the field of pressure gauges, and in particular to a pressure gauge with a protective function. Background Art

[0002] A pressure gauge is an instrument for measuring the pressure of fluid or gas. It usually consists of a dial that can read the pressure value and a pressure sensor connected to the system being tested. Pressure gauges can be used in industries, laboratories, medical equipment and other fields. Existing pressure gauges still have some problems when in use.

[0003] The existing pressure gauge shell is made of thinner metal, and the outside of the dial is transparent glass. When in use, it is easy to be damaged after a collision, affecting the normal use of the pressure gauge. In addition, the existing pressure gauge is usually fixed on the surface of a pipe or an instrument. The staff needs to observe the water pressure. When the staff is located in different directions of the pressure gauge, the staff needs to turn to the front of the pressure gauge for observation, and the pipe may affect the movement of the staff. The staff may need to take a long detour to observe the front of the pressure gauge, resulting in unnecessary waste of time. Therefore, we make improvements on this and propose a pressure gauge with a protective function. Utility Model Content

[0031] like Figure 1 - Figure 6 As shown, this embodiment proposes a pressure gauge with a protective function, including a pressure gauge body 1, a protective shell 2 is arranged on the outside of the pressure gauge body 1, and a protective mechanism 3 is arranged between the pressure gauge body 1 and the protective shell 2, an air intake pipe 4 is fixedly installed on the lower surface of the pressure gauge body 1, and a connecting pipe 5 is arranged on the lower side of the air intake pipe 4, and a connecting mechanism 6 is arranged between the air intake pipe 4 and the connecting pipe 5.

[0032] As a preferred embodiment, on the basis of the above-mentioned method, further, the protection mechanism 3 includes a connecting plate 301, and four connecting plates 301 are provided, and the four connecting plates 301 are arranged around the pressure gauge body 1, the connecting plates 301 are arranged in an arc shape, and a rubber pad 302 is fixedly installed on the surface of the connecting plate 301, and the rubber pad 302 is in contact with the pressure gauge body 1. The arc-shaped connecting plate 301 can make the rubber pad 302 on the surface of the connecting plate 301 better fit with the pressure gauge body 1 and protect the pressure gauge body 1.

[0033] As a preferred embodiment, on the basis of the above method, further, two connecting tubes 303 are arranged between the connecting plate 301 and the protective shell 2, and a sliding rod 304 is arranged between the two connecting tubes 303, sliding plates 305 are fixedly installed on the surfaces of both ends of the sliding rod 304, and the two sliding plates 305 are slidingly connected in the connecting tubes 303 on both sides, and a first spring 306 is fixedly installed between the surface of the sliding plate 305 and the inner wall of the connecting tube 303, and the sliding rod 304 and the sliding plate 305 on the surface can be buffered by the first spring 306, so as to achieve the purpose of buffering the protective shell 2 and avoid damage to the pressure gauge body 1.

[0034] As a preferred embodiment, on the basis of the above method, further, the connecting mechanism 6 includes a connecting block 601 and a connecting cover 602, and the connecting block 601 is fixedly installed on the surface of the intake pipe 4, and the connecting cover 602 is fixedly installed on the upper surface of the connecting pipe 5, and the connecting block 601 is arranged inside the connecting cover 602, and the connecting block 601 can be rotated inside the connecting cover 602, so that the pressure gauge body 1 can be rotated, which is convenient for observation by the staff.

[0035] As a preferred embodiment, on the basis of the above-mentioned method, further, a plurality of first teeth 603 are evenly fixedly installed on the inner wall of the connecting cover 602, a plurality of notches 604 are opened on the surface of the connecting block 601, and the second teeth 605 are slidably connected inside the notches 604, and a second spring 606 is fixedly installed between the second teeth 605 and the notches 604, and the second teeth 605 are meshingly connected with the first teeth 603 on the inner wall of the connecting cover 602. In the absence of external force, the second teeth 605 can be supported by the elastic force of the second spring 606 itself, so that the second teeth 605 are stuck between two adjacent first teeth 603, and the connecting block 601 is limited and fixed, and the surfaces on both sides of the first teeth 603 and the second teeth 605 are inclined, so that the second teeth 605 can slide into the notches 604 when rotating.

[0036] As a preferred embodiment, on the basis of the above method, further, a connecting ring 607 is fixedly installed on the lower surface of the connecting block 601, and a groove 608 is opened inside the connecting cover 602, and a sealing gasket 609 is fixedly installed inside the groove 608, and the connection method between the connecting ring 607 and the groove 608 is a snap-fit ​​connection, which is convenient for the connecting ring 607 to be snapped into the groove 608 and squeeze the internal sealing gasket 609, thereby improving the sealing performance between the connecting block 601 and the connecting cover 602.

[0037] Specifically, the working principle of this solution is as follows: during use, when the pressure gauge body 1 is hit, it will first touch the protective shell 2 and drive the protective shell 2 to move. Since the rubber pad 302 on the surface of the connecting plate 301 is in contact with the pressure gauge body 1, when the protective shell 2 moves, it will drive the connecting tube 303 hingedly connected on the surface to move, so that the sliding plates 305 on the surfaces of both sides of the sliding rod 304 slide in the connecting tubes 303 on both sides, and drive the first spring 306 on the surface to deform, and the protective shell 2 can be buffered by the elastic force of the first spring 306 itself.

[0038] When the staff is located in different directions of the pressure gauge and needs to observe the pressure gauge, the protective shell 2 outside the pressure gauge body 1 can be directly rotated to drive the pressure gauge body 1 and the air inlet pipe 4 on the lower side to rotate, and then the connecting block 601 is driven to rotate in the connecting cover 602 through the air inlet pipe 4. At the same time, the first teeth 603 on the inner wall of the connecting cover 602 will drive the second teeth 605 on the surface of the connecting block 601 to slide in the groove 604, and at the same time, the second spring 606 is deformed. When it is rotated to a certain angle, the second spring 606 will push the second teeth 605 out through its own elastic force, so that the second teeth 605 are stuck between two adjacent first teeth 603. The connecting block 601, the air inlet pipe 4 and the pressure gauge body 1 can be fixed without external force, avoiding the staff from having to take a long detour to observe the front of the pressure gauge, causing unnecessary waste of time. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
