Description

Technical Field

[0001] This utility model relates to the field of pressure sensor installation technology, and more specifically to a pressure sensor installation structure. Background Technology

[0002] A pressure sensor is a device that can measure and monitor the pressure or pressure changes acting on an object. Its principle is based on a series of physical effects and techniques, converting physical pressure changes into electrical signals to achieve measurement and monitoring functions.

[0003] A search revealed an existing patent (publication number: CN212779723U) that discloses a mounting structure specifically for pressure sensors. In use, a mounting mechanism is installed on the outside of the pressure sensor, and a sliding shell is fixed to the right end of a fixed shell. The fixed shell and sliding shell simultaneously enclose and protect the pressure sensor. The pressure sensor can be inspected through through holes in the top of the fixed shell and sliding shell. Silicone sheets on the inner sides of the fixed shell and sliding shell protect the outer side of the pressure sensor from friction damage, achieving a more stable and secure installation of the pressure sensor, providing stable protection, reducing the use of bolts, and preventing inconvenience in later disassembly. However, the inventors discovered the following problem with the existing technology during the development of this utility model: Although the aforementioned mounting structure for pressure sensors achieves the purpose of covering and protecting the pressure sensor through the shell structure, the sensing end of the pressure sensor is subject to wear when measuring external pressure and impact forces, thus reducing the service life of the pressure sensor and affecting the normal use of the equipment.

[0004] In view of this, the present invention proposes an installation structure for a pressure sensor. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pressure sensor mounting structure to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a pressure sensor mounting structure, including a mounting plate and a pressure sensor body disposed on the mounting plate, wherein a positioning component and a limiting component are respectively disposed on the upper surface of the mounting plate corresponding to the pressure sensor body;

[0007] The positioning assembly includes a fixed cover fixedly mounted on the upper surface of the mounting plate and a movable cover movably mounted on the upper surface of the mounting plate. The pressure sensor body is placed between the inner cavities of the fixed cover and the movable cover. The top of the fixed cover and the movable cover has a window reserved corresponding to the top sensing end of the pressure sensor body. A quick-release mounting assembly is provided between the fixed cover and the movable cover.

[0008] The limiting component includes a connecting plate movably mounted above the mounting plate. A wear-resistant column is detachably mounted on the surface of the connecting plate. The bottom end of the wear-resistant column contacts the sensing end of the pressure sensor body through a pre-drilled light hole on the surface of the connecting plate. A limiting slide rod is fixedly mounted on the bottom end of the connecting plate. A limiting cylinder is fixedly mounted on the surface of the mounting plate. The limiting slide rod is slidably connected to the top of the limiting cylinder.

[0009] Furthermore, the surface of the mounting plate is provided with four positioning grooves, which are arranged in a rectangular array at the four corners of the mounting plate.

[0010] As a further description of the above technical solution: by setting a positioning groove, the mounting plate can be installed and fixed.

[0011] Furthermore, a conduit is embedded on the back of the fixing cover, and a wire is provided on the surface of the pressure sensor body, with the wire passing through the inside of the conduit.

[0012] As a further description of the above technical solution: by setting up conduits, it is convenient to lay the conductors and connect them to the external power system.

[0013] Furthermore, the quick-release mounting assembly includes connecting plates symmetrically fixed between the fixed cover and the movable cover. Each of the two connecting plates has a transverse groove on its opposite side. A U-shaped clip is fitted onto the surface of the transverse groove. The U-shaped clip clamps and limits the fixed cover and the movable cover. The U-shaped clip is made of iron. A magnetic block is embedded in the inner wall of the transverse groove. The end of the U-shaped clip is magnetically attracted to the surface of the magnetic block.

[0014] As a further description of the above technical solution: by setting up a quick-release installation component, the U-shaped bracket is inserted into the transverse groove, and the magnetic block is used for magnetic adsorption and positioning, thereby achieving the effect of clamping and positioning the fixed cover and the movable cover. When it is necessary to disassemble and repair the pressure sensor body, the U-shaped bracket can be quickly removed, and then the movable cover can be directly taken out, thus facilitating the repair of the pressure sensor body.

[0015] Furthermore, a limiting ring is fixedly installed on the surface of the wear-resistant column. The limiting ring rests on the upper surface of the connecting plate, and the surface of the connecting plate is fixedly installed with clamps for clamping the limiting ring by bolts.

[0016] As a further description of the above technical solution: For the wear-resistant column, the clamping claws can be used to clamp the limiting ring, which can limit and fix the wear-resistant column. When the wear-resistant column is damaged, the clamping claws can be disassembled to remove the wear-resistant column for quick replacement, making maintenance convenient.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. Compared with the prior art, the installation structure of this pressure sensor places the pressure sensor body on the surface of the mounting plate and uses a fixed cover and a movable cover for protection, which improves the safety of the fixed end of the pressure sensor body. For the movable end of the pressure sensor body, a limiting slide rod and a limiting cylinder are used to restrict the movement path of the connecting plate. Then, a wear-resistant column is installed on the surface of the connecting plate. The wear-resistant column contacts the external object and transmits the pressure to the sensing end of the pressure sensor body through the wear-resistant column, thereby achieving the effect of protecting the sensing end of the pressure sensor body and ensuring that the pressure sensor body can be used for a long time.

[0019] 2. Compared with existing technologies, the installation structure of this pressure sensor features a positioning groove for fixing the mounting plate; a conduit for easy wiring; and a quick-release mounting assembly that uses a U-shaped clip to engage with the transverse groove and magnetically attaches to the fixed and movable covers for clamping. When disassembling and repairing the pressure sensor body, the U-shaped clip can be quickly removed, allowing direct removal of the movable cover for easy maintenance. For the wear-resistant column, a clamping jaw grips the limiting ring for secure positioning. If the wear-resistant column is damaged, the jaws can be removed for quick replacement, making maintenance convenient. Attached Figure Description

The surface of the mounting plate 1 is provided with four positioning grooves 9, which are distributed in a rectangular array at the four corners of the mounting plate 1.

[0027] The mounting plate 1 can be installed and fixed by setting the positioning groove 9.

[0028] The upper surface of the mounting plate 1 is provided with a positioning component and a limiting component respectively corresponding to the pressure sensor body 2.

[0029] The positioning assembly includes a fixed cover 3 fixedly mounted on the upper surface of the mounting plate 1 and a movable cover 4 movably mounted on the upper surface of the mounting plate 1. The pressure sensor body 2 is disposed between the inner cavities of the fixed cover 3 and the movable cover 4.

[0030] A conduit 10 is embedded on the back of the fixed cover 3, and a wire 11 is provided on the surface of the pressure sensor body 2. The wire 11 passes through the inside of the conduit 10.

[0031] By setting up conduit 10, it is convenient to lay and install wires 11, so as to achieve the purpose of installing pressure sensor body 2.

[0032] The top of the fixed cover 3 and the movable cover 4 have windows reserved on the top side sensing end of the pressure sensor body 2, and a quick-release mounting assembly is provided between the fixed cover 3 and the movable cover 4.

[0033] The quick-release installation assembly includes connecting plates 12 that are symmetrically fixed between the fixed cover 3 and the movable cover 4. Each of the two connecting plates 12 has a transverse groove on the side that is far apart from each other. A U-shaped bracket 13 is fitted onto the surface of the transverse groove, and the U-shaped bracket 13 clamps and limits the fixed cover 3 and the movable cover 4.

[0034] The U-shaped card holder 13 is made of iron. Magnetic blocks 14 are embedded in the inner wall of the horizontal groove, and the ends of the U-shaped card holder 13 are magnetically attached to the surface of the magnetic blocks 14.

[0035] It is worth noting that by setting up a quick-release installation component, the U-shaped bracket 13 is inserted into the transverse groove, and the magnetic block 14 is used for magnetic adsorption and positioning, thereby achieving the effect of clamping and positioning the fixed cover 3 and the movable cover 4. When it is necessary to disassemble and repair the pressure sensor body 2, the U-shaped bracket 13 can be quickly removed, and then the movable cover 4 can be taken out directly, thus facilitating the repair of the pressure sensor body 2.

[0036] It is worth noting that the installation structure of this pressure sensor places the pressure sensor body 2 on the surface of the mounting plate 1, and then uses the fixed cover 3 and the movable cover 4 for coverage and protection, thereby improving the safety of the fixed end of the pressure sensor body 2 during use.

[0037] The limiting assembly includes a connecting plate 5 movably mounted above the mounting plate 1. A wear-resistant column 6 is detachably mounted on the surface of the connecting plate 5.

The limiting slide rod 7 is slidably connected to the top of the limiting cylinder 8.

[0038] It is worth noting that, for the movable end of the pressure sensor body 2, the movement path of the connecting plate 5 is restricted by the limiting slide rod 7 and the limiting cylinder 8. Then, the wear-resistant column 6 is installed on the surface of the connecting plate 5. The wear-resistant column 6 contacts the external object and transmits the pressure to the sensing end of the pressure sensor body 2 through the wear-resistant column 6, thereby achieving the effect of protecting the sensing end of the pressure sensor body 2 and ensuring that the pressure sensor body 2 can be used for a long time.

[0039] It is worth noting that a zeroing operation should be performed before using the pressure sensor body 2 to eliminate the self-weight of the wear-resistant column 6 and other structures, and to ensure the accuracy of the pressure sensor body 2 during detection.

[0040] A limiting ring 15 is fixedly installed on the surface of the wear-resistant column 6, and the limiting ring 15 is placed on the upper surface of the connecting plate 5.
