DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 As shown, this embodiment provides a pressure transmitter that is easy to install, including a pipeline 1 and a transmitter body 2, the outer wall of the transmitter body 2 is fixedly connected with a mounting plate 3, the outer wall of the pipeline 1 is fixedly connected with a fixing plate 4, the mounting plate 3 is fixedly connected with a clamping mechanism 5 for fixing the mounting plate 3 and the fixing plate 4, the inside of the clamping mechanism 5 is fixedly connected with a limiting mechanism 6 for fixing the clamping mechanism 5, and the outer wall of the clamping mechanism 5 is fixedly connected with an auxiliary mechanism 7 for assisting the limiting mechanism 6 to fix the transmitter body 2.

[0020] The improvement of this embodiment is that:

[0021] When installing and connecting the existing pressure transmitter with the detected equipment, screws are mostly used to install the pressure transmitter. Installation by screws requires the use of external tools. However, some pressure transmitters may be installed in a small space. When the operator uses a wrench to install the screws, there may be problems with the installation. If the operator manually tightens the screws for installation, it is not only time-consuming and labor-intensive, but also impossible to tighten the screws, thereby failing to ensure the stability of the pressure transmitter after installation, reducing the use effect of the device. Therefore, by setting the clamping mechanism 5 and the limiting mechanism 6, when the transmitter body 2 is installed in a small space, the transmitter body 2 can be installed without the use of external tools, and the auxiliary mechanism 7 is cooperated to ensure the stability of the transmitter body 2 after installation, thereby improving the use effect of the device.

[0022] Considering the installation between the transmitter body 2 and the pipeline 1, the structure of the clamping mechanism 5 is further disclosed, such as Figure 3As shown, the clamping mechanism 5 includes a hollow column 51 fixedly connected above the mounting plate 3, and the bottom of the hollow column 51 passes through the mounting plate 3, the bottom of the hollow column 51 is inserted into the fixed plate 4, and a moving rod 52 is slidably connected inside the hollow column 51, and the top of the moving rod 52 passes through the hollow column 51. Pressing the moving rod 52 can drive the moving rod 52 to slide inside the hollow column 51, and the inner wall of the hollow column 51 above the mounting plate 3 is fixedly connected to a No. 1 return spring 53, and the side of the No. 1 return spring 53 away from the hollow column 51 is fixedly connected to the outer wall of the moving rod 52, and the No. 1 return spring 53 is set to drive the moving rod 52 to reset and move.

[0023] Considering the need to limit the position of the clamping mechanism 5, the structure of the limiting mechanism 6 is further disclosed, such as Figure 3 As shown, the limiting mechanism 6 includes a connecting rod 61 fixedly connected to the bottom of the moving rod 52. When the moving rod 52 moves up and down, the connecting rod 61 is driven to move up and down. The bottom of the connecting rod 61 is fixedly connected to the limiting rod 62. The connecting rod 61 moves up and down, driving the limiting rod 62 to move up and down. The inner wall of the hollow column 51 is symmetrically provided with through grooves, and the limiting balls 63 are slidably connected in the through grooves. The inner wall of the fixed plate 4 is symmetrically provided with limiting grooves, and the outer wall of the limiting ball 63 is snap-fitted with the inside of the limiting groove. When the hollow column 51 is inserted into the inside of the fixed plate 4, the pillar 8 is manually released. Under the force generated by the No. 1 reset spring 53 to restore the deformation, the moving rod 52, the connecting rod 61 and the limiting rod 62 are driven to reset and move, so that the limiting rod 62 resets and moves to squeeze the limiting ball 63, and the limiting ball 63 is squeezed into the limiting groove provided on the fixed plate 4, so as to realize the rapid installation of the transmitter body 2.

[0024] Considering the stability of the transmitter body 2 after installation, the structure of the auxiliary mechanism 7 is further disclosed, such as Figure 4 As shown, the auxiliary mechanism 7 includes an extrusion block 72 fixedly connected to the outer wall of the movable rod 52, and a rectangular groove 71 is symmetrically opened on the upper surface of the fixed plate 4, and a groove is opened on the side of the rectangular groove 71 close to the transmitter body 2, and a movable rod 73 is slidably connected in the groove. When the hollow column 51 is inserted into the fixed plate 4, the extrusion block 72 is driven to squeeze the movable rod 73, so that the other side of the movable rod 73 away from the extrusion block 72 abuts against the transmitter body 2, further improving the stability of the transmitter body 2 after installation, an annular plate 74 is fixedly connected in the groove, and the movable rod 73 is arranged through the annular plate 74, and a No. 2 reset spring 75 is fixedly connected to the side of the annular plate 74 away from the transmitter body 2, and the No. 2 reset spring 75 is fixedly connected to the outer wall of the movable rod 73 away from the side of the annular plate 74, and a No. 2 reset spring 75 is arranged, so that after the transmitter body 2 is disassembled, the movable rod 73 can be driven to reset and move under the force of the No. 2 reset spring 75 to restore the deformation.

[0025] Considering the convenience and stability of the installation between the transmitter body 2 and the pipeline 1, Figure 1 and Figure 2 The clamping mechanism 5, the limiting mechanism 6 and the auxiliary mechanism 7 are each provided with two groups, and are symmetrically arranged relative to the transmitter body 2. Two groups of clamping mechanisms 5, the limiting mechanism 6 and the auxiliary mechanism 7 are provided, so that the transmitter body 2 is more stable after installation. The tops of the two moving rods 52 are commonly fixedly connected with a support 8. The support 8 is provided so that by pressing the support 8 downward, the moving rods 52 in the two clamping mechanisms 5 can be driven to move, thereby improving the convenience during installation.

[0026] When the pressure transmitter of the utility model is easy to install, when it is used in practice, when it is necessary to install the transmitter body 2 between the pipeline 1, the support 8 is manually pressed downward to drive the moving rod 52 in the clamping mechanism 5 on both sides to move downward. At this time, the No. 1 return spring 53 is deformed by the force contraction, thereby driving the connecting rod 61 to move downward, and then driving the limiting rod 62 to move downward. At this time, the limiting rod 62 does not limit the limiting ball 63. Then the transmitter body 2 is inserted into the pipe mouth of the pipeline 1, and the hollow column 51 is also inserted into the inside of the fixing plate 4. When the lower surface of the mounting plate 3 is in contact with the upper surface of the fixing plate 4, the support 8 is manually released, and the No. 1 return spring 53 restores the force generated by the deformation, driving the moving rod 52 to reset and move, thereby driving the connecting rod 61 and the limiting rod 62 to reset and move. The limiting rod 62 resets and moves to squeeze the limiting ball 63, so that the limiting ball 63 can be clamped into the limiting groove provided in the fixing plate 4, so as to realize the rapid installation of the transmitter body 2.

[0027] When the hollow column 51 is inserted into the fixing plate 4, the squeezing block 72 is driven to squeeze the movable rod 73, so that the other side of the movable rod 73 away from the squeezing block 72 abuts against the transmitter body 2, further improving the stability of the transmitter body 2 after installation.

[0028] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
