[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-6 As shown, a pressure gauge with a protective structure includes a dial 1. The outside of the dial 1 is provided with a front shell 2 and a rear shell 3. The side wall of the front shell 2 is provided with a transparent protective shell 4. Here, the glass lens of the pressure gauge can be protected by the transparent protective shell 4, thereby making the pressure gauge more stable when in use.

[0024] Two mounting grooves 5 are fixedly connected to the outer surfaces of the front shell 2 and the rear shell 3 , and a clamping mechanism 6 is disposed inside the mounting groove 5 .

[0025] The clamping mechanism 6 includes a groove 601, the inner wall of which is provided with teeth 602 distributed at equal distances, the outer surface of the groove 601 is fixedly connected with an arc-shaped sliding rod 603, the outer surface of the arc-shaped sliding rod 603 is slidably connected to the side wall of one of the mounting grooves 5, and under the action of the arc-shaped sliding rod 603, support for the groove 601 is achieved, and the groove 601 can also be moved inside the mounting groove 5.

[0026] The outer surface of the arc-shaped sliding rod 603 at one end inside the mounting groove 5 is sleeved with a spring 604, and the spring 604 is fixedly connected to the outer surface of the groove 601, and the end of the spring 604 away from the groove 601 is fixedly connected to the inner wall of the mounting groove 5. The spring 604 is arranged here, and when the groove 601 moves, the spring 604 can generate elastic force, and then under the action of the elastic force, the groove 601 is more convenient to reset.

[0027] The clamping mechanism 6 also includes two L-shaped tooth plates 605 adapted to the teeth 602, the outer surface of the L-shaped tooth plate 605 is fixedly connected to a vertical rod 606, the outer surface of the vertical rod 606 is fixedly connected to a nail rod 607, and the outer surface of the nail rod 607 is slidably connected to the side wall of one of the mounting grooves 5. Here, when the teeth 602 are meshed with the L-shaped tooth plate 605, the spring 1 604 is in an elastic state. At the same time, when the nail rod 607 is pressed, the nail rod 607 and the vertical rod 606 can be moved, thereby separating the L-shaped tooth plate 605 and the teeth 602.

[0028] The two L-shaped tooth plates 605 are fixedly connected to the sides close to each other with a telescopic rod 608, and the ends of the two telescopic rods 608 away from the L-shaped tooth plates 605 are fixedly connected with a pad 609. The telescopic rods 608 are used to support the two L-shaped tooth plates 605, thereby making the L-shaped tooth plates 605 more stable when in use.

[0029] The outer surface of each telescopic rod 608 is sleeved with a spring 2 610, one end of which is fixedly connected to the outer surface of the L-shaped tooth plate 605, and the end of the spring 2 610 away from the L-shaped tooth plate 605 is fixedly connected to the outer surface of the pad 609. Here, when the L-shaped tooth plate 605 moves, the spring 2 610 can generate an elastic force, and under the action of the elastic force, the L-shaped tooth plate 605 is more convenient to reset, and the L-shaped tooth plate 605 is also more firmly engaged with the teeth 602.

[0030] It should be noted that in actual use of the device, the front shell 2 and the rear shell 3 are first assembled together, and then moved through the arc-shaped slider and the groove 601. When the groove 601 moves, it can engage with the L-shaped tooth plate 605, and the pressure gauge can be protected at this time. Conversely, when the pressure gauge needs to be taken out, the nail rod 607 is pressed, and the nail rod 607 can drive the vertical rod 606 to move, and further drive the L-shaped tooth plate 605 to move. At this time, the L-shaped tooth plate 605 can be separated from the teeth 602, and then the groove 601 can be reset under the action of the spring 1 604, so that the front shell 2 and the rear shell 3 can be separated.
