Description

Technical Field

[0001] This utility model relates to the field of pressure sensor technology, specifically a novel glass micro-fusion pressure sensor. Background Technology

[0002] The glass micro-fusion pressure sensor is a sensor that uses glass micro-fusion technology to achieve miniature size and high-precision pressure measurement. Based on MEMS technology, it employs a silicon strain gauge, which is sintered at high temperature and bonded to a stainless steel diaphragm. The four equivalent resistors of the silicon strain gauge form a Wheatstone bridge. When there is pressure from the medium on the other side of the stainless steel diaphragm, the diaphragm undergoes a slight deformation, causing a change in the bridge and generating a voltage signal proportional to the pressure change, thus achieving accurate measurement of the pressure.

[0003] When installing a glass micro-fusion pressure sensor, it is necessary to ensure that the sensor mounting hole corresponds precisely to the installation position on the measured equipment or pipeline. Some glass micro-fusion pressure sensors have requirements for the installation direction, and it takes time to determine the correct direction during installation. Furthermore, directional deviations may affect the measurement accuracy.

[0004] Therefore, this invention provides a novel glass micro-melting pressure sensor to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a novel glass micro-melting pressure sensor that solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel glass micro-melting pressure sensor, comprising an assembly cylinder, wherein a positioning and mounting assembly is provided inside the assembly cylinder; the positioning and mounting assembly comprises a ring, wherein a glass micro-melting pressure sensor body is rotatably connected to the inner wall of the ring, a protrusion is fixedly connected to the outer wall of the ring, a concave block is fixedly connected to the bottom of the glass micro-melting pressure sensor body, a first cross hole is provided at the bottom of the concave block, an auxiliary plate is fixedly connected between the inner walls of the assembly cylinder, a rotating ring block is rotatably connected inside the auxiliary plate, and a second cross hole is provided inside the rotating ring block.

[0007] Furthermore, a limiting groove is formed inside the side wall of the assembly cylinder, and the protrusion is slidably connected to the inner wall of the limiting groove.

[0008] The above technical solution is used to restrict bumps and rings.

[0009] Furthermore, a screw is rotatably connected between the inner walls of the assembly cylinder, and the screw is connected to the internal thread of one of the protrusions.

[0010] The above technical solution is used to make the bump and the ring move in a straight line.

[0011] Furthermore, an anti-slip block is fixedly connected to one end of the screw.

[0012] The above technical solution is used to rotate the screw.

[0013] Furthermore, a sleeve block is fixedly connected to the outer wall of the assembly cylinder, and the positioning and installation assembly also includes an equipment docking component, on one side of which an insertion rod is fixedly connected.

[0014] The above technical solution is used for docking and positioning.

[0015] Furthermore, the positioning and mounting assembly also includes bolts that are threadedly connected to the sleeve and the insert.

[0016] The above technical solution is used to fix the sleeve and the insertion rod.

[0017] Beneficial effects

[0018] This invention provides a novel glass micro-melting pressure sensor. Compared with the prior art, it has the following advantages:

[0019] 1. This novel glass micro-melting pressure sensor, by aligning the sleeve block with the insertion rod and inserting the insertion rod into the sleeve block, facilitates quick positioning and easy docking between the glass micro-melting pressure sensor body and the equipment docking parts, and then fixes it with bolts.

[0020] 2. This novel glass micro-fusion pressure sensor is installed by inserting a torsion rod with the same diameter as the first and second cross holes into them. By turning the anti-slip block, the screw rotates. The rotation of the screw, under the constraint of the limiting groove, causes the protrusion to move linearly along with the ring, thereby moving the glass micro-fusion pressure sensor body closer to the interface of the equipment docking part. This, combined with the anti-slip block, allows the torsion rod to rotate, causing the rotating ring block to rotate. This, in turn, causes the glass micro-fusion pressure sensor body to rotate through the concave block, thus screwing it onto the interface of the equipment docking part, completing the installation of the glass micro-fusion pressure sensor body. This installation position is more precise, easier to control, and easier to position. Attached Figure Description

[0028] It should be noted that in the description of the embodiments of this application, the terms "front," "rear," "left," "right," "up," "down," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 5This application provides a novel glass micro-melting pressure sensor, comprising an assembly cylinder 1, with a positioning and mounting assembly 2 disposed inside the assembly cylinder 1. The positioning and mounting assembly 2 includes a ring 22, with a glass micro-melting pressure sensor body 21 rotatably connected to the inner wall of the ring 22. A protrusion 23 is fixedly connected to the outer wall of the ring 22. A concave block 26 is fixedly connected to the bottom of the glass micro-melting pressure sensor body 21, with a first cross hole 27 at the bottom of the concave block 26. An auxiliary plate 28 is fixedly connected between the inner walls of the assembly cylinder 1, with a rotating ring block 29 rotatably connected inside the auxiliary plate 28, and a second cross hole 210 inside the rotating ring block 29. A limiting groove 211 is formed inside the side wall of the assembly cylinder 1, and the protrusion 23 is slidably connected to the inner wall of the limiting groove 211. A screw 24 is rotatably connected between the inner walls of the assembly cylinder 1, and the screw 24 is threadedly connected to the inside of one of the protrusions 23. An anti-slip block 25 is fixedly connected to one end of the screw 24.

[0031] In specific implementation: A torsion bar with the same diameter as the first cross hole 27 and the second cross hole 210 is inserted into the first cross hole 27 and the second cross hole 210. By turning the anti-slip block 25, the screw 24 is rotated. The rotation of the screw 24, under the restriction of the limiting groove 211, causes the protrusion 23 to drive the ring 22 to move linearly together, thereby moving the glass micro-melting pressure sensor body 21 closer to the interface of the equipment docking part 213. This, together with the anti-slip block 25, simultaneously turns the torsion bar to drive the rotating ring block 29 to rotate, and then drives the glass micro-melting pressure sensor body 21 to rotate through the concave block 26, so that it is screwed into the interface of the equipment docking part 213, thus completing the installation of the glass micro-melting pressure sensor body 21. This installation position is more precise, easier to control and easier to position.

[0032] Reference Figures 1 to 5 In one aspect of this embodiment, a sleeve block 212 is fixedly connected to the outer wall of the assembly cylinder 1, and the positioning and mounting assembly 2 further includes an equipment docking part 213, on one side of which an insertion rod 214 is fixedly connected. The positioning and mounting assembly 2 also includes a bolt 215, which is threadedly connected to the sleeve block 212 and the insertion rod 214.

[0033] In practice: by aligning the sleeve 212 with the insertion rod 214, the insertion rod 214 is inserted into the sleeve 212, which facilitates the quick positioning and docking of the glass micro-melting pressure sensor body 21 with the equipment docking part 213. Then, it is fixed with bolts 215.

[0034] All electrical devices in this plan are powered by an external power source.

[0035] Working principle: By aligning the sleeve 212 with the insertion rod 214, the insertion rod 214 is inserted into the sleeve 212, facilitating quick positioning and docking of the glass micro-melting pressure sensor body 21 with the equipment docking part 213. It is then fixed with bolts 215. A torsion bar with the same diameter as the first cross hole 27 and the second cross hole 210 is inserted into the first cross hole 27 and the second cross hole 210. Twisting the anti-slip block 25 rotates the screw 24, which in turn moves within the limiting groove 211. Under the control, the protrusion 23 causes the ring 22 to move linearly together, thereby moving the glass micro-melting pressure sensor body 21 closer to the interface of the equipment docking part 213. This, together with the anti-slip block 25, simultaneously turns the torsion bar to make the rotating ring block 29 rotate, and then through the concave block 26, makes the glass micro-melting pressure sensor body 21 rotate, so that it is screwed at the interface of the equipment docking part 213, thereby completing the installation of the glass micro-melting pressure sensor body 21. This installation position is more precise, easier to control and easier to position.
