[0013] 1. When installing a pressure gauge, the operator first tightens the screw plate and the round rod to disengage the lead screw and the second nut. The clamp is then placed on the outer surface of the pipe. Simultaneously, the hollow lead screw and rubber gasket are aligned with the pipe hole. The lead screw is then aligned with the second nut and slowly tightened, causing the clamp to gradually grip the pipe. At this point, the rubber gasket will be tightly against the pipe hole.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figures 1-4 This utility model provides a digital electrical contact pressure gauge, which includes a pressure gauge housing 1, a round tube 2 fixedly connected to the bottom end of the pressure gauge housing 1, a slot 24 opened on the back of the pressure gauge housing 1, a retaining plate 16 slidably arranged inside the pressure gauge housing 1, a clamp 4 arranged on the outer surface of the round tube 2, a first blocking ring 7 and a second blocking ring 8 fixedly connected to the outer surface of the round tube 2, and a round rod 10 rotatably arranged inside the right end of the clamp 4.

[0025] Specifically: the design of the fixed connection of the round tube 2 on the outer surface of 1 and the slot 24 allows the clamping plate 16 to quickly detach from and insert into the interior of the pressure gauge housing 1. At the same time, the first blocking ring 7 and the second blocking ring 8 make the position of the clamp 4 more stable and prevent it from easily shaking.

[0026] A third blocking ring 11 is fixedly connected to the outer surface of the round rod 10, a locking rod 12 is fixedly connected to the inside of the round rod 10, and a screw plate 13 is fixedly connected to the top of the round rod 10.

[0027] Specifically: The design of the third blocking ring 11 and the locking rod 12 makes the position of the round rod 10 more stable during the tightening process and prevents it from sliding up and down easily. At the same time, the design of the tightening plate 13 makes the force-bearing area larger during the tightening process, making it easier to tighten.

[0028] A lead screw 14 is fixedly connected to the bottom end of the round rod 10. A second nut 9 is rotatably connected to the outer surface of the bottom end of the lead screw 14. The upper surface of the second nut 9 is fixedly connected to the lower surface of the clamp 4.

[0029] Specifically: through the rotational connection of clamp 14 and second nut 9, the round rod 10 can be tightened by pulling clamp 14 through second nut 9 when it is turned, thus achieving a rapid clamping effect.

[0030] A rotating shaft 15 is fixedly connected to the back of the card plate 16, a first fixing plate 18 is fixedly connected to the outer surface of the rotating shaft 15, and a second fixing plate 19 is fixedly connected to the back of the first fixing plate 18.

[0031] Specifically: the rotating shaft 15 fixedly connected to the back of the card plate 16 increases the stability of the second fixed plate 19 by the first fixed plate 18.

[0032] A torsion spring 17 is movably sleeved on the outer surface of the rotating shaft 15. One end of the torsion spring 17 is fixedly connected to the upper surface of the second fixed plate 19, and the other end of the torsion spring 17 is fixedly connected to a protrusion 20. A snap-fit ​​rod 21 is fixedly connected to the front of the protrusion 20.

[0033] Specifically: The two ends of the torsion spring 17, which is movably sleeved on the outer surface of the rotating shaft 15, are fixed to the second fixed plate 19 and the protrusion 20 respectively, so that the torsion spring 17 will not twist when it is elastically deformed, and the elastic deformation drives the locking rod 21 to move.

[0034] A hollow lead screw 3 is fixedly connected to the bottom end of the round tube 2. A first nut 5 is movably sleeved on the outer surface of the hollow lead screw 3. A rubber gasket 6 is provided at the bottom end of the first nut 5.

[0035] Specifically: the hollow screw 3 at the bottom of the round tube 2 causes the rubber gasket 6 to be pressed when the worker tightens the first nut 5.

[0036] A third fixing plate 22 is fixedly connected to the back of the pressure gauge housing 1. The upper surface of the third fixing plate 22 and the lower surface of the locking rod 21 are movably locked together.

[0037] Specifically: the movable engagement between the locking rod 21, which is fixedly connected to the back of the pressure gauge housing 1, and the third fixing plate 22 allows the operator to more quickly separate and lock the locking rod 21 from the pressure gauge housing 1.

[0038] A limiting plate 23 is fixedly connected to the back of the rotating shaft 15. The diameter of the limiting plate 23 is larger than the inner diameter of the torsion spring 17.

[0039] Specifically, the design of the limiting plate 23 ensures that the torsion spring 17 will not detach from the outer surface of the rotating shaft 15 during the torsion process.

[0040] Working principle: When installing a pressure gauge, the operator first tightens the screw plate 13 and the round rod 10, disengaging the lead screw 14 and the second nut 9. The clamp 4 is then placed on the outer surface of the pipe. Simultaneously, the hollow lead screw 3 and the rubber gasket 6 are aligned with the pipe hole. The lead screw 14 is then aligned with the second nut 9 and slowly tightened, causing the clamp 4 to gradually clamp the pipe. At this point, the rubber gasket 6 will be tightly pressed against the pipe hole. Then, the first nut 5 is tightened, further securing the rubber gasket 6 to the pipe. When the operator needs to maintain the pressure... When the gauge is inside, press down the outermost end of the locking rod 21. At this time, due to the downward pressure, one end of the torsion spring 17 is squeezed, causing the torsion spring 17 to elastically contract. At the same time, the inner end of the locking rod 21 is separated from the outer surface of the third fixing plate 22. At this time, pull the locking plate 16 outward, so that the locking plate 16 is separated from the outside of the pressure gauge housing 1. After the maintenance is completed, pinch the outermost end of the locking rod 21. When the locking plate 16 is completely inserted into the inside of the pressure gauge housing 1, release the outermost end of the locking rod 21 to lock the outer surface of the third fixing plate 22.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
