Description

Technical Field

[0001] This utility model relates to the field of gas detector technology, and in particular to an easy-to-maintain gas detector. Background Technology

[0002] A gas detector is an instrument for detecting gas concentration. It can continuously monitor the concentration of a gas in the air up to its lower explosive limit. Therefore, gas detectors are widely used in various industries where flammable or toxic gases are present, such as gas, petrochemical, metallurgy, steel, coking, and power, making them ideal monitoring instruments for ensuring the safety of property and personnel. However, some existing gas detectors are inconvenient to install and require maintenance after installation. They are mostly fixed with bolts, making disassembly cumbersome, and their exposure to the outside makes them susceptible to impacts, resulting in low maintenance efficiency. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: an easy-to-maintain gas detector, including a mounting base and a detector body. A sliding rod is fixedly installed inside the mounting base. A slider is slidably connected to the surface of the sliding rod. A spring is sleeved on the surface of the sliding rod. A lower connecting seat is fixedly installed on the surface of the slider. A connecting rod is rotatably connected inside the lower connecting seat. An upper connecting seat is rotatably connected to the other end of the connecting rod. A mounting plate is fixedly installed on the surface of the upper connecting seat. A fixing block is fixedly installed on the inner side of the slider. A pressure block is fixedly installed on the surface of the fixing block. A mating interface is opened on the surface of the mounting base. The side of the detector body is fixedly installed on a positioning edge.

[0005] Preferably, a first screw hole is formed on the surface of the pressure block, and a second screw hole is formed on the surface of the positioning edge. Both the first and second screw holes are internally threaded with hexagon socket head cap screws. The use of hexagon socket head cap screws here ensures a stable connection of the detector body and prevents the detector from falling off due to loosening. Furthermore, the use of hexagon socket head cap screws reduces exposed fasteners, making the overall device more aesthetically pleasing.

[0006] Preferably, the number of connecting rods is four sets, and the four sets of connecting rods are symmetrically distributed on the bottom surface of the mounting plate. Here, the four sets of connecting rods provide multi-point support, making the detector installation more stable, reducing shaking and uneven stress problems. At the same time, the symmetrical distribution design ensures uniform stress on the mounting plate and improves the service life of the equipment.

[0007] Preferably, a limiting groove is formed on the surface of the mounting plate, and a limiting strip is fixedly installed on the inner side of the mating interface. Here, the limiting strip and the limiting groove cooperate to prevent the mounting plate from detaching from the mating interface, so that the mounting plate can stably mate with the mounting base.

[0008] Preferably, there are two sets of pressure blocks and positioning edges, which are symmetrically distributed on both sides of the detector body. This ensures that the detector is subjected to uniform force during installation or disassembly, avoiding damage caused by force on one side.

[0009] Preferably, the mounting base has a housing that engages with its surface, a plug is fixedly mounted on the bottom of the housing, the mounting base has a slot, and the housing has a viewing window whose position corresponds to that of the detector body. This engagement connection facilitates easy assembly and disassembly without additional tools, greatly improving maintenance efficiency. Furthermore, the housing protects the detector body, preventing damage from exposure.

[0010] Preferably, a sponge strip is fixedly installed inside the housing, located at the edge of the viewing window and surrounding the surface of the detector body. Here, the sponge strip enhances the detector's protection and improves the overall airtightness of the device, preventing the influence of external environmental factors such as dust and moisture on the detector.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the internal hexagon screws in screw holes No. 1 and No. 2 are removed, and the detector body is pressed down. The detector body drives the mounting plate to press down. During the pressing process, the mounting plate will cause the connecting rod to rotate. At the same time, the connecting rod will drive the slider to move on the sliding rod. The slider will drive the fixed block to move. The fixed block will drive the pressure block to move. When the pressure block is away from the positioning edge, the detector body will separate from the mounting base. Personnel can easily remove the detector body from the mounting base so that personnel can quickly maintain and replace the detector body.

[0013] 2. In this utility model, a detachable housing is provided on the outside of the mounting base. The disassembly and assembly process of the housing is simplified by the snap-fit ​​connection and the cooperation of the plug slot, which significantly improves the maintenance efficiency. The viewing window on the surface of the housing makes it easy to observe the operating status of the detector, while the internally installed wrap-around sponge strip further enhances the protective capability of the equipment and improves the airtightness.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1

[0026] Please see Figure 1-6This utility model provides a technical solution: an easy-to-maintain gas detector, including a mounting base 1 and a detector body 16. A slide rod 2 is fixedly installed inside the mounting base 1, and a slider 3 is slidably connected to the surface of the slide rod 2. A spring 7 is sleeved on the surface of the slide rod 2. A lower connecting seat 4 is fixedly installed on the surface of the slider 3. A connecting rod 5 is rotatably connected inside the lower connecting seat 4, and an upper connecting seat 6 is rotatably connected to the other end of the connecting rod 5. A mounting plate 10 is fixedly installed on the surface of the upper connecting seat 6. There are four sets of connecting rods 5, symmetrically distributed on the bottom surface of the mounting plate 10. The four sets of connecting rods 5 provide multi-point support, making the detector installation more stable and reducing shaking and uneven force distribution. Simultaneously, the symmetrical distribution design ensures uniform force distribution on the mounting plate 10, improving the service life of the equipment. A fixing block 8 is fixedly installed inside the slider 3, and a pressure block 9 is fixedly installed on the surface of the fixing block 8. A screw hole 12 is formed on the surface of the pressure block 9, and the surface of the positioning edge 17... The device has a second screw hole 18. The internal threads of the first screw hole 12 and the second screw hole 18 are connected to hexagon socket screws 13. The use of hexagon socket screws 13 ensures the connection of the detector body 16 is stable and prevents the detector from falling off due to loosening. In addition, the hexagon socket screws 13 reduce the number of exposed fasteners, making the overall device more aesthetically pleasing. The surface of the mounting base 1 has a mating interface 14, and the surface of the mounting plate 10 has a limit groove 11. A limit strip 15 is fixedly installed on the inner side of the mating interface 14. The limit strip 15 and the limit groove 11 cooperate to prevent the mounting plate 10 from coming off the mating interface 14, so that the mounting plate 10 is stably mated with the mounting base 1. The side of the detector body 16 is fixedly installed on the positioning edge 17. There are two sets of pressure blocks 9 and positioning edges 17. The two sets of pressure blocks 9 and positioning edges 17 are symmetrically distributed on both sides of the detector body 16, so that the detector is subjected to force evenly during installation or disassembly, avoiding damage caused by force on one side.

[0027] Example 2

[0028] Please see Figure 1 and Figure 7 The mounting base 1 has a housing 20 that is snapped onto its surface. A plug 21 is fixedly installed at the bottom of the housing 20. The mounting base 1 has a slot 19. The housing 20 has a viewing window 22 on its surface. The position of the viewing window 22 corresponds to the position of the detector body 16. The snap-fit ​​connection makes it easy to install and remove without additional tools, which greatly improves maintenance efficiency. In addition, the housing 20 can protect the detector body 16 and prevent it from being exposed and damaged. A sponge strip 23 is fixedly installed inside the housing 20. The sponge strip 23 is located at the edge of the viewing window 22 and surrounds the surface of the detector body 16. The sponge strip 23 enhances the protection of the detector and improves the overall airtightness of the equipment, preventing the influence of external environment such as dust and moisture on the detector.

[0029] Working principle: When disassembling and maintaining the gas detector, the housing 20 must first be removed from the mounting base 1. The housing 20 protects the detector body 16, preventing it from being exposed and damaged. Then, remove the hexagonal socket screws 13 from screw holes 12 and 18. Press down on the detector body 16, causing the mounting plate 10 to press down. During this pressing process, the connecting rod 5 rotates, which in turn moves the slider 3 on the sliding rod 2. The slider 3 then moves the fixing block 8, which in turn moves the pressure block 9. During this process, the slider 3 compresses the spring 7. When the pressure block 9 moves away from the positioning edge 17, the detector body 16 separates from the mounting base 1. At this point, personnel can easily remove the detector body 16 from the mounting base 1 for quick maintenance and replacement.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
