Description

Technical Field

[0001] The utility model relates to the technical field of pressure transmitters, in particular to a pressure transmitter protection cover. Background Art

[0002] A pressure transmitter is an electronic device used to measure, convert, and transmit pressure signals. It converts the physical pressure parameters of gases, liquids, etc. sensed by the pressure measuring element sensor into a standard electrical signal to be fed to secondary instruments such as indicator alarms, recorders, and regulators for measurement, indication, and process control.

[0003] Due to the limitations of the installation location in certain specific application scenarios, some pressure transmitters cannot be installed in indoor environments or dedicated protective boxes. This limitation makes these transmitters completely lack the necessary protection devices, and therefore they will inevitably be exposed to direct sunlight and rain. Under long-term exposure to sunlight and rain, the shell material of the pressure transmitter will accelerate aging due to ultraviolet radiation and humidity erosion. In this way, the stability and service life of the equipment will be seriously affected, and may even lead to premature scrapping of the equipment, causing unnecessary losses and safety hazards to production operations.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0021] Reference Figure 1 、 Figure 3 and Figure 5 As shown, the utility model provides a technical solution: a pressure transmitter protective cover, comprising a first protective shell 1, one end of the first protective shell 1 is rotatably connected to the second protective shell 2, a pressure transmitter body 3 is installed inside the first protective shell 1 and the second protective shell 2, one side of the second protective shell 2 is fixedly connected to a first connecting block 4, one side of the first protective shell 1 is fixedly connected to a second connecting block 5, a movable groove 6 is provided inside the second connecting block 5, a connecting rod 7 is slidably connected inside the movable groove 6, an end of the connecting rod 7 away from the first connecting block 4 is fixedly connected to a control block 8, an end of the connecting rod 7 close to the first connecting block 4 is fixedly connected to a movable block 9, an installation groove 10 is provided inside the movable block 9, a first spring 11 is fixedly connected inside the installation groove 10, the other side of the first spring 11 is fixedly connected to a fixed block 12, a fixed groove 13 is provided on one side of the first connecting block 4, and the surface of the movable block 9 is aligned with the first The internal sliding connection of the connecting block 4, the surface of the fixed block 12 and the internal sliding connection of the fixed groove 13, by closing the first protective shell 1 and the second protective shell 2, and then moving the connecting rod 7 so that the connecting rod 7 pushes the movable block 9 into the interior of the first connecting block 4, the elasticity of the first spring 11 will automatically push the fixed block 12 into the interior of the fixed groove 13, so that the first protective shell 1 and the second protective shell 2 are fixed. When the pressure transmitter body 3 needs to be removed from the interior of the first protective shell 1 and the second protective shell 2, it is only necessary to press the fixed block 12 to disengage the fixed block 12 from the interior of the fixed groove 13 to quickly release the installation. By arranging the first protective shell 1 and the second protective shell 2 on the surface of the pressure transmitter body 3, it can be ensured that when performing pressure testing outdoors, the object pressure transmitter body 3 is protected from direct sunlight and erosion by bad weather such as wind and rain, which can effectively improve the service life of the pressure transmitter body 3.

[0022] Reference Figure 4As shown, in this embodiment: a first sliding groove 14 is opened on both sides of the movable groove 6, and a first slider 15 is fixedly connected to both sides of the connecting rod 7. The surface of the first slider 15 is slidably connected to the inside of the first sliding groove 14. By moving the first slider 15 inside the first sliding groove 14, the moving trajectory of the connecting rod 7 can be limited, providing guidance for the movement of the connecting rod 7, so that the connecting rod 7 will not shake when moving.

[0023] Reference Figure 4 As shown, in this embodiment: the surface of the connecting rod 7 is slidably connected to the second spring 16, one end of the second spring 16 is fixedly connected to the second connecting block 5, and the other end of the second spring 16 is fixedly connected to the control block 8. By providing the second spring 16, the elasticity of the second spring 16 can automatically drive the connecting rod 7 to reset when the limit is released, without the need to manually move the connecting rod 7 out from the inside of the first connecting block 4.

[0024] Reference Figure 5 As shown, in this embodiment: the surface of the fixed block 12 is fixedly connected to the limiting ring 17, and the surface of the limiting ring 17 is slidably connected to the inside of the mounting groove 10. By setting the limiting ring 17, the moving position of the fixed block 12 can be limited to ensure that the fixed block 12 is not dislodged from the inside of the mounting groove 10 due to the excessive elasticity of the first spring 11, thereby ensuring the stability of this structure.

[0025] Reference Figure 1 As shown, in this embodiment: a sealing gasket 18 is installed at the joint of the first protective shell 1 and the second protective shell 2, and a sealing gasket 18 is installed at the joint of the pressure transmitter body 3 and the first protective shell 1 and the second protective shell 2. By arranging the sealing gasket 18 at the joint of the first protective shell 1, the second protective shell 2 and the pressure transmitter body 3, the overall sealing performance of the equipment can be significantly improved. In this way, rainwater and other external liquids will not be able to easily penetrate into the internal structure of the equipment, thereby effectively preventing erosion and potential damage to the components of the pressure transmitter body 3.

[0026] Reference Figure 2 As shown, in this embodiment: a plurality of heat dissipation holes 19 are opened at one end of the second protective shell 2. By opening a plurality of heat dissipation holes 19 with downward slant openings at one end of the second protective shell 2, it is possible to effectively prevent the pressure transmitter body 3 from being overheated or having poor heat dissipation effect, which may cause abnormal equipment testing.

[0027] Reference Figure 5As shown, in this embodiment: the outer diameter of the fixing block 12 is adapted to the inner diameter of the fixing groove 13. By adapting the outer diameter of the fixing block 12 to the inner diameter of the fixing groove 13, the fixation between the first protective shell 1 and the second protective shell 2 can be made more stable. This precise matching can not only improve the structural stability of the overall equipment, but also effectively improve the accuracy and reliability of the equipment operation.

[0028] Working principle: By closing the first protective shell 1 and the second protective shell 2, and then moving the connecting rod 7 so that the connecting rod 7 pushes the movable block 9 into the interior of the first connecting block 4, the elasticity of the first spring 11 will automatically push the fixed block 12 into the interior of the fixed groove 13, so that the first protective shell 1 and the second protective shell 2 are fixed. When the pressure transmitter body 3 needs to be removed from the interior of the first protective shell 1 and the second protective shell 2, it is only necessary to press the fixed block 12 to disengage the fixed block 12 from the interior of the fixed groove 13 to release the limit. By arranging the first protective shell 1 and the second protective shell 2 on the surface of the pressure transmitter body 3, it can be ensured that when performing pressure testing outdoors, the object pressure transmitter body 3 is protected from direct sunlight and erosion by bad weather such as wind and rain, which can effectively improve the service life of the pressure transmitter body 3. By moving the first slider 15 inside the first slide groove 14, the moving trajectory of the connecting rod 7 can be limited, providing guidance for the movement of the connecting rod 7, so that the connecting rod 7 will not shake when moving. By arranging the second spring 16, the elasticity of the second spring 16 can make the fixed groove 13 and the fixed block 12 release the limit. When the first connecting block 4 is in the correct position, the connecting rod 7 is automatically driven to reset, and there is no need to manually remove the connecting rod 7 from the inside of the first connecting block 4. The limit ring 17 can limit the movement of the fixing block 12, ensuring that the fixing block 12 does not fall out of the inside of the mounting groove 10 due to the excessive elasticity of the first spring 11, thereby ensuring the stability of this structure. By providing a sealing gasket 18 at the joints between the first protective shell 1, the second protective shell 2 and the pressure transmitter body 3, the overall sealing performance of the device can be significantly improved. In this way, rainwater and other external liquids will not easily penetrate into the internal structure of the device, thereby effectively preventing erosion and potential damage to the components of the pressure transmitter body 3. By opening a number of downwardly inclined heat dissipation holes 19 at one end of the second protective shell 2, the pressure transmitter body 3 can effectively prevent abnormal testing of the device due to excessive heat or poor heat dissipation. By making the outer diameter of the fixing block 12 and the inner diameter of the fixing groove 13 compatible with each other, the fixation between the first protective shell 1 and the second protective shell 2 can be more firmly established. This precise fit not only improves the structural stability of the entire device, but also effectively improves the accuracy and reliability of the device operation.
