[0025] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0026] As Figures 1 to 6 shown in the figure, in Embodiment 1, a pressure transmitter that is convenient for installation and adjustment includes a pressure transmitter body 1, a mounting base 2, a height adjustment mechanism 3, a mounting plate 4, and a fixing mechanism 5; the pressure transmitter body 1 is arranged at the lifting end of the height adjustment mechanism 3 through the mounting base 2, and the fixed end of the height adjustment mechanism 3 is arranged on the upper end surface of the mounting plate 4, and the fixing mechanism 5 is connected to the lower end surface of the mounting plate 4.

[0027] The installation height of the pressure transmitter body 1 can be adjusted through the height adjustment mechanism 3, which is suitable for different installation environments, such as environments with narrow space and inconsistent thickness of pipeline insulation layers, and has strong practicability; the fixing mechanism 5 at the bottom of the device facilitates the installation of the pressure transmitter body 1 and can quickly fix the device on the test pipe fitting, which is more efficient and convenient.

[0028] Embodiment 2 is a further improvement based on Embodiment 1, and the specific details are as follows:

[0029] The height adjustment mechanism 3 includes an outer housing 31, a lifting plate 32, and a screw 33; the screw 33 is rotatably arranged on the mounting plate 4, the outer housing 31 is arranged on the upper end surface of the mounting plate 4 and sleeved outside the screw 33, a screw hole 321 matching the screw 33 is penetrated through the lifting plate 32, and the lifting plate 32 is threadedly connected with the screw hole 321; the mounting base 2 is connected to the lifting plate 32 through a support rod 6.

[0030] By adjusting the rotation of the screw 33, the lifting or lowering of the lifting plate 32 is driven to realize the height adjustment of the pressure transmitter, with a simple structure and convenient adjustment.

[0031] Embodiment 3 is a further improvement based on Embodiment 2, and the specific details are as follows:

[0032] The height adjustment mechanism 3 further includes a rotating rod 34. A first bevel gear 35 is fixedly sleeved on the screw rod 33. A second bevel gear 36 is provided at one end of the rotating rod 34. The first bevel gear 35 matches the second bevel gear 36. The other end of the rotating rod 34 extends out of the outer housing 31 and is connected to the knob 37.

[0033] Rotate the rotating rod 34. The rotating rod 34 drives the second bevel gear 36 to rotate. The second bevel gear 36 drives the first bevel gear 35 to rotate. The first bevel gear 35 can drive the screw rod 33 to rotate, thereby driving the lifting plate 32 to rise or fall, and further driving the pressure transmitter body 1 to rise or fall, realizing the height adjustment of the pressure transmitter body 1.

[0034] In specific implementation, a rotating seat 42 is provided on the mounting plate 4. The rotating rod 34 is supported at two points through the rotating seat 42 and the outer housing 31, enabling better cooperation between the first bevel gear 35 and the second bevel gear 36. In addition, a spring can be sleeved on the rotating rod 34. The spring is arranged between the knob 37 and the outer housing 31. When height adjustment is required, push in the rotating rod 34 to engage the second bevel gear 36 with the first bevel gear 35. When adjustment is not needed, the spring pushes the rotating rod 34 outwards to disengage the second bevel gear 36 from the first bevel gear 35, thereby avoiding height adjustment caused by accidental touch.

[0035] Example 4. This example is a further improvement based on Example 2, and the details are as follows:

[0036] A rotating ball 38 is connected to the bottom of the screw rod 33. A spherical groove 41 is provided in the mounting plate 4. The rotating ball 38 rotates in the spherical groove 41. The arrangement of the rotating ball 38 and the spherical groove 41 makes the screw rod 33 more stable during rotation and reduces friction. In specific implementation, the bottom of the screw rod 33 can also be connected to the mounting plate 4 through a bearing. The screw rod 33 is fixedly connected to the inner ring of the bearing, and the outer ring of the bearing is connected to the mounting plate 4.

[0037] Example 5. This example is a further improvement based on Example 4, and the details are as follows:

[0038] Two symmetrically arranged limit blocks 381 are provided on the outer surface of the rotating ball 38. A sliding groove 411 is provided on the spherical surface of the spherical groove 41. The limit blocks 381 slide in the sliding groove 411. The arrangement of the limit blocks 381 and the sliding groove 411 can limit the rotating ball 38 and enhance the stability of the lifting screw rod 33 during rotation.

[0039] Example 6. This example is a further improvement based on Example 2, and the details are as follows:

[0040] The outer housing 31 is cylindrical, the cross-section of the lifting plate 32 is circular, and two sliding blocks 322 are symmetrically arranged on the peripheral wall of the lifting plate 32. A slideway 311 matching the cross-section of the sliding block 322 is arranged on the inner peripheral wall of the outer housing 31 along its height direction, and the sliding block 322 is slidably arranged in the slideway 311.

[0041] Embodiment 7 is a further improvement based on any one of Embodiments 2 to 6, and the specific content is as follows:

[0042] A limiting piece 39 is connected to the top of the screw rod 33, and the diameter of the limiting piece 39 is larger than the diameter of the screw hole 321. This can prevent the lifting plate 32 from detaching from the screw rod 33.

[0043] Embodiment 8 is a further improvement based on Embodiment 1, and the specific content is as follows:

[0044] The fixing mechanism 5 includes two arc-shaped clamping plates 51 and a bolt 52. One end of each of the two clamping plates 51 is rotatably connected to the bottom of the mounting plate 4, and fixing strips 53 are respectively connected to the other ends of the two clamping plates 51. The bolt 52 threadedly penetrates through the two fixing strips 53.

[0045] Embodiment 9 is a further improvement based on Embodiment 8, and the specific content is as follows:

[0046] The fixing mechanism 5 further includes a connecting housing 54. The connecting housing 54 is sleeved on the two fixing strips 53, and the bolt 52 threadedly penetrates through the connecting housing 54 and the two fixing strips 53.

[0047] Embodiment 10 is a further improvement based on any one of Embodiments 8 or 9, and the specific content is as follows:

[0048] An anti-slip layer 55 is provided on the inner wall of the clamping plate 51. In specific implementation, the anti-slip layer 55 can be made of a frosted material or a rubber material. Preferably, a rubber material is used, which can enhance the stability when the clamping plate 51 is installed.

[0049] Working principle: When in use, when the installation space of the pressure transmitter body 1 is relatively narrow, rotate the rotating rod 34. The rotation of the rotating rod 34 drives the rotation of the second bevel gear 36. The rotation of the second bevel gear 36 drives the rotation of the first bevel gear 35. The rotation of the first bevel gear 35 can drive the rotation of the screw rod 33, and then can drive the lifting plate 32 to descend. When the lifting plate 32 descends, it can drive the pressure transmitter body 1 to descend, and then can adjust the height of the pressure transmitter body 1. Clamp the two clamping plates 51 on the test pipe fitting, place the fixing strip 53 inside the connecting housing 54, and rotate the bolt 52 to fix the fixing strip 53 and the connecting housing 54, and then can fix the two clamping plates 51, which is convenient for installing the pressure transmitter body 1. This device can make the pressure transmitter body 1 adapt to installation in different environments, has strong practicability, and can meet the installation requirements in different environments.
