[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0018] A quick connection and detection device for diaphragm pressure gauges, such as Figures 1-3 As shown, the device includes a pressure gauge 1, a connecting cylinder 2 fitted at the lower part of the pressure gauge 1, a fastening ring 3 threadedly connected to the lower part of the pressure gauge 1 to fix the connecting cylinder 2, an installation tube 4 snapped onto the lower part of the connecting cylinder 2, a positioning block on the installation tube 4, a threaded structure at the lower part of the installation tube 4 for easy connection with a pipeline, a sealing gasket 5 connected to the lower part of the connecting cylinder 2, a sealing ring 6 also connected to the lower part of the connecting cylinder 2, three fixing blocks 7 connected to the upper part of the connecting cylinder 2, each fixing block 7 rotatably connected to a rotating clamp 8, each rotating clamp 8 having an assisting block, a rotating ring 9 rotatably connected to the middle of the installation tube 4, three fastening bolts 10 threadedly connected to the middle of the installation tube 4, each fastening bolt 10 having an assisting component connected to the lower part of the fastening bolt 10, the fastening bolt 10 being able to lock adjacent rotating clamps 8, and an installation plate 11 connected to the pressure gauge 1, the installation plate 11 having four installation holes.

[0019] It should be noted that a diaphragm pressure gauge is a special type of pressure measuring device, mainly used to measure the pressure of corrosive, viscous, easily crystallizing, or solid-particle-containing media. When using a diaphragm pressure gauge to test the pressure of a fluid medium, firstly, the installation pipe 4 is connected to the pipeline through the lower threaded structure. Then, the connecting sleeve 2 is fitted onto the pressure gauge 1, and the fastening ring 3 is rotated to fix the connecting sleeve 2 to the lower part of the pressure gauge 1. Next, the connecting sleeve 2 is clamped onto the installation pipe 4 by the positioning block. The sealing gasket 5 and the sealing ring 6 ensure that a sealed space is formed between the installation pipe 4 and the inside of the connecting sleeve 2. Then, flip the rotating clip 8 downwards so that the rotating clip 8 contacts the rotating ring 9. Then rotate the rotating ring 9 so that the fastening bolt 10 is inside the adjacent rotating clip 8, thereby locking the rotating clip 8 with the fastening bolt 10. This connection method makes it more convenient to connect, disassemble, and replace the pressure gauge 1. At the same time, the fastening bolt 10 can be rotated to adjust the fastening bolt 10 to a suitable height to accommodate different locking degrees of the rotating clip 8. In addition, when other equipment needs to be installed on the pressure gauge 1, the equipment can be installed on the mounting plate 11, which gives the pressure gauge 1 an extension function.

[0020] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
