[0017] refer to Figure 1 and 2 , detailing the implementation process of connecting and installing the pressure gauge:

[0018] A pressure gauge connection mechanism comprises a shell 11 and a connection frame 12 rotatably connected to the shell 11. The shell 11 is the shell of the pressure gauge. The connection frame 12 is used to install the shell 11. The shell 11 can be rotated to facilitate the pressure gauge to be viewed from any direction after the pressure gauge is installed. An upper plate 13 is threadedly connected to the connection frame 12. The installation depth of the connection frame 12 can be adjusted by rotating the upper plate 13, so that pressure can be measured at different installation depths. The connection frame 12 is detachably connected to an upper frame 22. The upper frame 22 is fixedly connected to a bent frame 21. The other end of the bent frame 21 is fixedly connected to a lower frame 23. A push rod 41 is threadedly connected to the lower frame 23, so that the shell 11 is correspondingly installed in a through hole to be measured. The push rod 41 is screwed, and the push rod 41 is fed axially under the guidance of the thread on the lower frame 23, so that the parts for installing the pressure gauge are fixed, thereby realizing the connection of the pressure gauge.

[0019] In combination with the above embodiments, the following functions can also be achieved:

[0020] refer to Figure 1 , 3 and 4, detailing the implementation process of fixing the connection frame 12:

[0021] The connecting frame 12 is threadedly connected with a lower plate 32, so that by adjusting the positions of the upper plate 13 and the lower plate 32 on the connecting frame 12, the installation depth of the connecting frame 12 is adjusted, and then the installation depth of the pressure gauge is adjusted. The lower end of the lower plate 32 is fixedly connected with a sealing gasket 31, so that when the parts for installing the pressure gauge are clamped under the rotation of the push rod 41, the sealing gasket 31 is pressed down by the upper frame 22 at the upper end to deform and seal the through hole for installing the pressure gauge, so as to prevent leakage of the fluid when measuring the pressure of the fluid, thereby affecting the pressure measurement effect.

[0022] In combination with the above embodiments, the following functions can also be achieved:

[0023] refer to Figure 4 , the implementation process of rotating the lower plate 32 without tools is described in detail:

[0024] The lower plate 32 is fixedly connected with a rotating handle II 33 , and the lower plate 32 can be easily rotated by holding the rotating handle II 33 , thereby making it easier to adjust the installation depth of the pressure gauge.

[0025] In combination with the above embodiments, the following functions can also be achieved:

[0026] refer to Figure 4 , the implementation process of rotating the upper plate 13 to protect the pressure gauge is described in detail:

[0027] The upper plate 13 is fixedly connected with a rotating handle Ⅰ14, so that the upper plate 13 can be easily rotated by holding the rotating handle Ⅰ14, so that the pressure gauge can be protected more stably and the relative movement between the housing 11 and the upper frame 22 can be prevented to cause damage to the pressure gauge.

[0028] In combination with the above embodiments, the following functions can also be achieved:

[0029] refer to Figure 2 , the implementation process of more firmly sealing the connection frame 12 and the connection is described in detail:

[0030] The lower end of the connecting frame 12 is conical, so that when the pressure gauge is installed, the connecting frame 12 can be sealed by deforming at the connection point through the cone, and the deformation of the sealing gasket 31 can ensure the sealing of the connection.

[0031] In combination with the above embodiments, the following functions can also be achieved:

[0032] refer to Figure 4 , the implementation process of ensuring that the sealing gasket 31 can deform to ensure sealing is described in detail:

[0033] The sealing pad 31 is made of rubber, so as to ensure that sealing can be achieved by deforming under the pressure applied by the upper frame 22 and the push rod 41 .

[0034] In combination with the above embodiments, the following functions can also be achieved:

[0035] refer to Figure 1 and 5 , the implementation process of preventing the ejector rod 41 from damaging the parts when clamping the parts for installing the pressure gauge is described in detail:

[0036] The push rod 41 is rotatably connected with a buffer pad 42, so that when the push rod 41 is clamped and installed, the push rod 41 and the parts for installing the pressure gauge can be buffered to prevent scratches. The buffer pad 42 can also be deformed to increase the stability of the installed pressure gauge and prevent the pressure gauge from shaking.

[0037] In combination with the above embodiments, the following functions can also be achieved:

[0038] refer to Figure 1 and 5 , the implementation process of facilitating the rotation of the handheld ejector rod 41 is described in detail:

[0039] The push rod 41 is fixedly connected with a flower handle 43, so that the push rod 41 can be rotated by holding the flower handle 43, thereby facilitating the installation and removal of the pressure gauge by hand.

[0040] In combination with the above embodiments, the following functions can also be achieved:

[0041] refer to Figure 1 , 3 and 5, detailing the implementation process of ensuring that the top rod 41 rotates steadily:

[0042] The lower end of the lower frame 23 is processed with a stabilizing tube 24 threadedly connected to the push rod 41, so as to ensure that the push rod 41 can rotate stably by extending the installation length of the push rod 41, thereby ensuring the stability of the pressure gauge during disassembly and assembly.

[0043] In combination with the above embodiments, the following functions can also be achieved:

[0044] refer to Figure 3 , the implementation process of the protective cushion 42 is described in detail:

[0045] The lower frame 23 is processed with a stepped groove for accommodating the buffer pad 42 , so that when the push rod 41 is not fixed, the buffer pad 42 is placed in the stepped groove for protection.
