Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid level gauge technology, specifically a novel gas-conducting liquid level gauge. Background Technology
[0002] The core principle of a gas-conducting level gauge is based on the direct proportionality between liquid static pressure and liquid level. When the liquid level changes, the static pressure generated by the liquid column also changes accordingly. The gas-conducting level gauge transmits the liquid pressure to the sensor through a gas-conducting tube. The sensor converts the pressure signal into an electrical signal, thereby measuring the liquid level.
[0003] In existing equipment, a venting tube is used to contact the liquid surface. The front end of the venting tube is usually a probe or a balance cover. It transmits the liquid pressure into the venting tube and then conducts it to the sensor. The pressure sensed by the sensor is proportional to the liquid level. The pressure signal is converted into a standard electrical signal by a conversion circuit, thereby realizing the measurement of the liquid level.
[0004] However, in actual use, although the above-mentioned equipment can measure the liquid level through the air guide tube and the balance cover, when the liquid level gauge is stored or moved, its probe and air guide tube will become tangled and knotted due to excessive length when piled up. In view of this, we propose a new type of air-guided liquid level gauge. Utility Model Content
[0005] The purpose of this invention is to provide a novel gas-conducting level gauge to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel gas-guided level gauge, comprising a sensitive device assembly, a gas-guided pipe provided on the outer wall of the sensitive device assembly, a balance cover provided at the end of the gas-guided pipe, a fixing assembly provided on the outer wall of the sensitive device assembly, the fixing assembly comprising a fixing sleeve fixedly connected to the outer wall of the sensitive device assembly, a handle fixedly connected to the outer wall of the balance cover, a turntable rotatably mounted on the outer wall of the fixing sleeve, an elastic telescopic plate fixedly connected to the outer wall of the turntable, and a connecting plate fixedly connected to the end of the elastic telescopic plate;
[0007] A fixed head is fixedly connected to the outer wall of the connecting plate. A bidirectional threaded rotating rod is rotatably installed on the inner wall of the fixed sleeve. A threaded slider is threadedly connected to the outer wall of the bidirectional threaded rotating rod. An L-shaped plate is fixedly connected to the outer wall of the threaded slider. An extrusion rubber block is fixedly connected to the outer wall of the L-shaped plate. A limit groove is opened at the end of the bidirectional threaded rotating rod.
[0008] Preferably, the outer wall of the fixing head is adapted to the inner wall of the limiting groove, so that the fixing head can be smoothly inserted into the limiting groove.
[0009] Preferably, the center line of the elastic telescopic plate and the center line of the turntable are on the same straight line, so that the elastic telescopic plate can rotate smoothly.
[0010] Preferably, the number of extrusion blocks is several, and the several extrusion blocks are arranged in a linear array on the outer wall of the L-shaped plate.
[0011] Preferably, the outer wall of the fixing sleeve is provided with a storage component, the storage component includes a pressing groove, the pressing groove is formed on the outer wall of the fixing sleeve, and a protruding rubber block is fixedly connected to the inner wall of the pressing groove.
[0012] Preferably, the number of the raised rubber blocks is several, and the several raised rubber blocks are arranged in a linear array on the inner wall of the pressing groove.
[0013] Preferably, the outer wall of the grip is adapted to the inner wall of the pressing groove, so that the grip can be inserted into the pressing groove when pressed.
[0014] Compared with the prior art, this utility model provides a novel gas-conducting liquid level gauge, which has the following beneficial effects:
[0015] 1. This new type of air-guided level gauge, when rotated by a bidirectional threaded rod, causes the limited threaded slider to move the L-shaped plate and the extrusion block, thus allowing the handle to be stably fixed when the L-shaped plate and the extrusion block move to both sides. After the threaded slider moves to its maximum limit, the connecting plate can be pulled to extend the elastic telescopic plate. Then, after the fixed head is aligned with the limit groove, the elastic telescopic plate can be released, allowing the fixed head to be stably inserted into the limit groove. This ensures that the balance cover can be stably stored when not in use, preventing the balance cover from getting tangled or knotted through the air-guided tube.
[0016] 2. In this new type of air-guided level gauge, when the L-shaped plate and the extrusion block are displaced to both sides, the set pressing groove allows the handle to be positioned more stably. At the same time, under the pressure of the extrusion block, the handle will further conform to the pressing groove and the protruding block, thereby further limiting the handle and improving the overall practicality.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a novel gas-guided level gauge, including a sensitive device assembly 1, a gas guide tube 2 provided on the outer wall of the sensitive device assembly 1, a balance cover 3 provided at the end of the gas guide tube 2, a fixing assembly 4 provided on the outer wall of the sensitive device assembly 1, the fixing assembly 4 including a fixing sleeve 402, the fixing sleeve 402 being fixedly connected to the outer wall of the sensitive device assembly 1, a handle 401 being fixedly connected to the outer wall of the balance cover 3, a turntable 403 being rotatably mounted on the outer wall of the fixing sleeve 402, an elastic telescopic plate 404 being fixedly connected to the outer wall of the turntable 403, and a connecting plate 405 being fixedly connected to the end of the elastic telescopic plate 404.
[0024] Furthermore, the fixing head 406 is fixedly connected to the outer wall of the connecting plate 405, and the inner wall of the fixing sleeve 402 is rotatably mounted with a bidirectional threaded rotating rod 407. The outer wall of the bidirectional threaded rotating rod 407 is threadedly connected with a threaded slider 408. The outer wall of the threaded slider 408 is fixedly connected with an L-shaped plate 409. The outer wall of the L-shaped plate 409 is fixedly connected with an extrusion rubber block 410. A limit groove 411 is opened at the end of the bidirectional threaded rotating rod 407.
[0025] In this embodiment of the utility model, the outer wall of the fixing head 406 is adapted to the inner wall of the limiting groove 411, so that the fixing head 406 can be smoothly inserted into the limiting groove 411. The center line of the elastic telescopic plate 404 and the center line of the turntable 403 are on the same straight line, so that the elastic telescopic plate 404 can rotate smoothly. The number of extrusion rubber blocks 410 is several, and the several extrusion rubber blocks 410 are arranged in a linear array on the outer wall of the L-shaped plate 409.
[0026] Furthermore, the outer wall of the fixed sleeve 402 is provided with a storage and insertion component 5, which includes a pressing groove 501. The pressing groove 501 is formed on the outer wall of the fixed sleeve 402. The inner wall of the pressing groove 501 is fixedly connected with a protruding rubber block 502. The number of protruding rubber blocks 502 is several, and the several protruding rubber blocks 502 are arranged in a linear array on the inner wall of the pressing groove 501. The outer wall of the handle 401 is adapted to the inner wall of the pressing groove 501, so that the handle 401 can be inserted into the pressing groove 501 when it is pressed.
[0027] In this utility model, during daily storage, the handle 401 can be placed on the outer wall of the fixing sleeve 402, while the L-shaped plate 409 can pass smoothly through the middle of the handle 401. Then, the bidirectional threaded rod 407 can be rotated, causing the threaded slider 408, which is limited, to move the L-shaped plate 409 and the extrusion block 410. This allows the handle 401 to be stably fixed when the L-shaped plate 409 and the extrusion block 410 move to both sides. After the threaded slider 408 moves to its maximum limit, the connecting plate 405 can be pulled to extend the elastic telescopic plate 404. Then, after the fixing head 406 is aligned with the limiting groove 411, the elastic telescopic plate 404 can be released, allowing the fixing head 406 to be smoothly inserted into the limiting groove 411. This ensures that the balance cover 3 can be stably stored when not in use, preventing the balance cover 3 from getting tangled and knotted through the air guide tube 2.
[0028] When the L-shaped plate 409 and the extrusion block 410 are moved to both sides, the pressing groove 501 allows the handle 401 to be positioned more stably. At the same time, under the pressure of the extrusion block 410, the handle 401 will further conform to the pressing groove 501 and the protruding block 502, thereby further limiting the handle 401 and further improving the overall practicality.
[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
