Chemical instrument with quick dismounting structure

Abstract

This utility model relates to the field of chemical instrumentation technology and discloses a chemical instrument with a quick-assembly and disassembly structure, including a mounting plate and an instrument body. Mounting seats are fixedly connected to the left and right sides of the top of the mounting plate, and mounting blocks are fixedly connected to the left and right sides of the bottom of the instrument body. An mounting groove is formed on the inner side of the top of the mounting seat. This chemical instrument with a quick-assembly and disassembly structure allows for quick installation of the instrument body by the return spring extending inwards after losing its force, which in turn moves a guide rod inwards. The guide rod moves a movable plate inwards, causing the inner side of the limiting block to engage with the limiting groove, thus enabling quick installation. Pulling a pull plate outwards causes the limit block to move outwards via the guide rod and movable plate, removing the inner side of the limit block from the limiting groove. Moving the instrument body upwards further removes the bottom of the mounting block from the mounting groove, enabling quick disassembly of the instrument body.

Description

Technical Field

[0001] This utility model relates to the field of chemical instrumentation technology, specifically a chemical instrument with a quick-assembly and disassembly structure. Background Technology

[0002] Chemical instrumentation plays a crucial role in the chemical industry. These instruments are indispensable tools, not merely simple measuring devices, but key factors ensuring smooth chemical production processes, improving efficiency, and enhancing product quality. Firstly, chemical instrumentation monitors and controls various critical parameters such as temperature, pressure, flow rate, and liquid level. These parameters directly impact the rate of chemical reactions, conversion rates, and the quality of the final product. By monitoring these parameters in real time, chemical instrumentation ensures optimal production conditions, preventing accidents and quality issues caused by parameter fluctuations. Secondly, chemical instrumentation requires high precision and stability. In chemical production, even minute parameter changes can significantly affect results. Therefore, chemical instrumentation must possess high-precision measurement capabilities and stable performance to ensure data accuracy and reliability. This is essential for decision-making and control in chemical production.

[0003] Existing chemical instruments are mostly fixed with fastening screws during installation. If the tightening force is too tight, the instrument may be damaged due to excessive pressure; if the tightening force is insufficient, the instrument may loosen under vibration or impact, affecting the accuracy and reliability of the measurement. At the same time, because chemical production environments are usually corrosive, high-temperature, and high-pressure, fastening screws are susceptible to corrosion and wear, resulting in weak connections and affecting the stability and service life of the instrument. In addition, installing and removing fastening screws requires a lot of time and effort, especially in some space-constrained or hard-to-access locations, which increases the difficulty of instrument installation and maintenance.

[0004] To address the aforementioned issues, we have made improvements by proposing a chemical instrument with a quick-assembly and disassembly structure. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a chemical instrument with a quick-assembly and disassembly structure, including a mounting plate and an instrument body. Mounting seats are fixedly connected to the left and right sides of the top of the mounting plate, and mounting blocks are fixedly connected to the left and right sides of the bottom of the instrument body. An mounting groove is formed on the inner side of the top of the mounting seat, and the bottom of the mounting block is engaged in the inner cavity of the mounting groove. A placement cavity is formed on the outer side of the inner surface of the mounting seat. Guide grooves are formed on the left and right sides of the mounting seat, and a guide rod is passed through the inner cavity of the guide groove. A return spring is sleeved on the surface of the guide rod. A movable plate is fixedly connected to the inner side of the guide rod, and a limiting block is fixedly connected to the inner side of the movable plate. A limiting groove is formed on the bottom of the outer side of the mounting block, and the inner side of the limiting block is engaged in the inner cavity of the limiting groove.

[0006] Preferably, the inner surface of the mounting base is provided with a sliding groove on both the front and back sides of the placement cavity, and a slider is fixedly connected to both the front and back sides of the movable plate, with the outer side of the slider slidably connected to the inner cavity of the sliding groove.

[0007] Preferably, a pull plate is fixedly connected to the outer side of the guide rod, and a locking block is fixedly connected to the front and back sides of the inner side of the pull plate. The mounting base has a locking groove on both the left and right sides, and on the front and back sides of the guide groove. The locking block is engaged in the inner cavity of the locking groove.

[0008] Preferably, the outer side of the return spring is fixedly connected to the outer side of the inner wall of the placement cavity, and the inner side of the return spring is fixedly connected to the surface of the guide rod.

[0009] Preferably, a connecting pipe is provided through the middle of the inner surface of the mounting plate, and an instrument pipe is connected to the bottom of the instrument body, with the instrument pipe being snapped into the inner cavity of the connecting pipe.

[0010] Preferably, a sealing ring is bonded to the outer surface of the instrument tube, and the outer side of the sealing ring is in contact with the inner wall of the connecting tube.

[0011] Compared with the prior art, this utility model provides a chemical instrument with a quick-assembly and disassembly structure, which has the following beneficial effects:

[0012] 1. This chemical instrument with a quick-release structure uses a mounting block whose bottom engages with the inner cavity of the mounting groove to initially limit the instrument body. The return spring, having lost its force, extends inwards to restore its deformation and moves the guide rod inwards. The guide rod then moves the movable plate inwards, causing the inner side of the limiting block to engage with the limiting groove, thus enabling quick installation of the instrument body. By pulling the pull plate outwards, the pull plate, through the guide rod and movable plate, moves the limiting block outwards, causing the inner side of the limiting block to no longer engage with the limiting groove. Further upward movement of the instrument body removes the bottom of the mounting block from the mounting groove, allowing for quick disassembly of the instrument body.

[0013] 2. This chemical instrument with a quick-assembly and disassembly structure can effectively improve the stability and smoothness of the moving plate during horizontal movement by setting a sliding groove and a slider. By setting a locking block and a locking groove, the pull plate can be limited, improving the stability of the guide rod during use, thereby improving the locking effect between the limiting block and the limiting groove. By setting a sealing ring, the stability of the connecting pipe and the instrument pipe during the connection process can be effectively improved. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A chemical instrument with a quick-assembly and disassembly structure includes a mounting plate 1 and an instrument body 2. Mounting seats 3 are fixedly connected to the left and right sides of the top of the mounting plate 1, and mounting blocks 4 are fixedly connected to the left and right sides of the bottom of the instrument body 2. A mounting groove 9 is opened on the inner side of the top of the mounting seat 3. The bottom of the mounting block 4 is engaged in the inner cavity of the mounting groove 9. A placement cavity 11 is opened on the outer side of the inner surface of the mounting seat 3. Guide grooves 12 are opened on the left and right sides of the mounting seat 3. A guide rod 13 is inserted through the inner cavity of the guide groove 12. A return spring 14 is sleeved on the surface of the guide rod 13. A movable plate 15 is fixedly connected to the inner side of the guide rod 13. A limit block 10 is fixedly connected to the inner side of the movable plate 15. A limit groove 16 is opened on the bottom of the outer side of the mounting block 4. The inner side of the limit block 10 is engaged in the inner cavity of the limit groove 16. The outer side of the return spring 14 is fixedly connected to the outer side of the inner wall of the placement cavity 11. The inner side of the return spring 14 is fixedly connected to the surface of the guide rod 13.

[0022] Through the above technical solution, after the bottom of the mounting block 4 is engaged with the inner cavity of the mounting groove 9 to initially limit the instrument body 2, the reset spring 14, due to the loss of force, recovers its deformation and extends inward, driving the guide rod 13 to move inward. The guide rod 13 drives the movable plate 15 to move inward, so that the inner side of the limiting block 10 is engaged in the limiting groove 16, thereby enabling the instrument body 2 to be quickly installed. By pulling the pull plate 5 outward, the pull plate 5 drives the limiting block 10 to move outward through the guide rod 13 and the movable plate 15, so that the inner side of the limiting block 10 is no longer engaged in the limiting groove 16. Then, the instrument body 2 is moved upward, so that the bottom of the mounting block 4 is no longer engaged in the mounting groove 9, enabling the instrument body 2 to be quickly disassembled.

[0023] Specifically, the inner surface of the mounting base 3 is provided with a sliding groove 17 on both the front and back sides of the placement cavity 11. The front and back sides of the movable plate 15 are fixedly connected with sliders 18. The outer side of the sliders 18 is slidably connected to the inner cavity of the sliding groove 17. The outer side of the guide rod 13 is fixedly connected with a pull plate 5. The front and back sides of the inner side of the pull plate 5 are fixedly connected with locking blocks 19. The left and right sides of the mounting base 3 are provided with locking grooves 20 on both the front and back sides of the guide groove 12. The locking blocks 19 are engaged in the inner cavity of the locking grooves 20. A connecting pipe 6 is provided through the middle of the inner surface of the mounting plate 1. The bottom of the instrument body 2 is connected to an instrument tube 7. The instrument tube 7 is engaged in the inner cavity of the connecting pipe 6. A sealing ring 8 is bonded to the outer surface of the instrument tube 7. The outer side of the sealing ring 8 is in contact with the inner wall of the connecting pipe 6.

[0024] Through the above technical solutions, by setting the sliding groove 17 and the slider 18, the stability and smoothness of the movable plate 15 during horizontal movement can be effectively improved. By setting the locking block 19 and the locking groove 20, the pull plate 5 can be limited, improving the stability of the guide rod 13 during use, thereby improving the locking effect between the limiting block 10 and the limiting groove 16. By setting the sealing ring 8, the stability of the connecting pipe 6 and the instrument pipe 7 during the connection process can be effectively improved.

[0025] In use, first pull the pull plate 5 outward. The pull plate 5 drives the guide rod 13 to move outward. The guide rod 13 drives the return spring 14 to deform and press outward. Then, move the instrument body 2 downward so that the bottom of the mounting block 4 is engaged in the mounting groove 9. At this time, the instrument tube 7 is inserted into the inner cavity of the connecting pipe 6. At the same time, the outer side of the sealing ring 8 is tightly fitted with the inner wall of the connecting pipe 6. Then, release the pull plate 5. At this time, the pull plate 5 recovers its deformation and extends inward due to the loss of force, and drives the guide rod 13 to move inward. The guide rod 13 drives the movable plate 15 to move inward, so that the inner side of the limit block 10 is engaged in the limit groove 16, and the instrument body 2 is quickly installed.

[0026] When it is necessary to disassemble the instrument body 2, first pull the pull plate 5 outward. The pull plate 5 drives the limiting block 10 to move outward through the guide rod 13 and the movable plate 15, so that the inner side of the limiting block 10 is no longer stuck in the limiting groove 16. Then move the instrument body 2 upward so that the bottom of the mounting block 4 is no longer stuck in the mounting groove 9, and quickly disassemble the instrument body 2.
