[0001] This utility model relates to the field of gas leak prevention technology, and in particular to a rare gas leak prevention alarm structure. Background Technology
[0002] Rare gases are widely used in fields such as electronics manufacturing, aerospace, medical equipment, and precision instruments due to their stable chemical properties. They are usually stored in special containers (such as special steel cylinders and sealed pipeline systems) under high pressure or high purity.
[0003] Currently, one type of rare gas leak detection alarm structure may have some errors due to external wind force when the sensor detects a gas leak, resulting in poor practicality. Furthermore, this type of rare gas leak detection alarm structure lacks a mechanism to protect the display, which may be damaged by impact during transportation or outdoor use, thus having significant limitations and poor practicality. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the existing technology where sensors may produce certain errors due to external wind force when detecting gas leaks, and there is no mechanism to protect the display. The display may be damaged by collisions during transportation or outdoor use. Therefore, a rare gas leak prevention alarm structure is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rare gas leak-proof alarm structure, comprising an alarm body, a display installed at the front end of the alarm body, a sensor installed at the bottom end of the alarm body, a cable outlet installed at the side end of the alarm body, a buzzer alarm light installed at the side end of the alarm body, an indicator light installed at the top end of the alarm body, a connecting sleeve fixed at the bottom end of the alarm body outside the sensor, a plurality of first springs fixed on the inner wall of the connecting sleeve, a protective sleeve fixed at one end of each first spring, the end of the protective sleeve away from the first spring penetrating the connecting sleeve and located on the outside of the connecting sleeve, a transparent protective cover provided at the front end of the alarm body outside the display, and four limiting blocks fixed at the front end of the alarm body outside the transparent protective cover, one of the limiting blocks having a buckle structure for locking and limiting the transparent protective cover.
[0006] Preferably, the buckle structure includes an inner cavity formed at one end of the limiting block, a second spring fixed on the inner wall of the inner cavity, a locking post fixed at one end of the second spring, and the end of the locking post away from the second spring passing through the limiting block and movably inserted into the transparent protective cover.
[0007] Preferably, a push plate is fixed to the top of the locking post, and the end of the push plate away from the locking post passes through the limiting block and is located outside the limiting block. One end of the limiting block is provided with a moving groove that matches the push plate.
[0008] Preferably, a second limiting block is fixed at both ends of the outer wall of the locking post, and a second limiting groove matching the second limiting block is opened at both ends of the inner wall of the inner cavity of the limiting block.
[0009] Preferably, the inner wall of the protective sleeve is fixed with a first limiting block at both ends, and the inner wall of the connecting sleeve is provided with a first limiting groove that matches the first limiting block at both ends.
[0010] Preferably, a rubber ring is fixed at one end of the protective sleeve outside the connecting sleeve.
[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a connecting sleeve and a protective sleeve, when the sensor is connected to the pipe, the protective sleeve will move towards the pipe under the action of the first spring, thereby covering the connection point between the pipe and the sensor. This directly prevents external wind from entering from the connection point between the sensor and the pipe and causing an impact, resulting in stronger stability. In addition, the device can directly protect the display by setting up a transparent protective cover, protecting it from impacts and greatly increasing the service life of the device, making it more practical.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0015] 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.
[0016] Example 1, as Figure 1-4 As shown, this utility model provides a rare gas leak prevention alarm structure, including an alarm body 1, a display 2 installed at the front end of the alarm body 1, a sensor 3 installed at the bottom end of the alarm body 1, a cable outlet 4 installed at the side end of the alarm body 1, a buzzer alarm light 5 installed at the side end of the alarm body 1, an indicator light 6 installed at the top end of the alarm body 1, a connecting sleeve 7 fixed at the bottom end of the alarm body 1 outside the sensor 3, a plurality of first springs 8 fixed on the inner wall of the connecting sleeve 7, a protective sleeve 9 fixed at one end of the first spring 8, the end of the protective sleeve 9 away from the first spring 8 passing through the connecting sleeve 7 and located on the outside of the connecting sleeve 7, a transparent protective cover 13 is provided at the front end of the alarm body 1 outside the display 2, and four limiting blocks 14 are fixed at the front end of the alarm body 1 outside the transparent protective cover 13, one of the limiting blocks 14 is provided with a buckle structure 15 for locking and limiting the transparent protective cover 13.
[0017] The overall effect of Embodiment 1 is that, through the setting of the connecting sleeve 7 and the protective sleeve 9, when the sensor 3 is connected to the pipe, the protective sleeve 9 will move towards the pipe under the action of the first spring 8, thereby covering the connection point between the pipe and the sensor 3, directly preventing external wind from entering from the connection point between the sensor 3 and the pipe and causing an impact, thus enhancing stability. In addition, through the setting of the transparent protective cover 13, the device can directly protect the display 2, protecting it from impacts, greatly increasing the service life of the device and enhancing its practicality. Through the setting of the snap-fit structure 15, the transparent protective cover 13 can be quickly installed and removed, avoiding the cumbersome, time-consuming, and labor-intensive problem of bolt installation and removal, further enhancing its practicality.
[0018] Example 2, as Figure 1-4As shown, the snap-fit structure 15 includes an inner cavity 1501 formed at one end of the limiting block 14. A second spring 1502 is fixed to the inner wall of the inner cavity 1501. A snap-fit post 1503 is fixed to one end of the second spring 1502. The end of the snap-fit post 1503 away from the second spring 1502 passes through the limiting block 14 and is movably inserted into the transparent protective cover 13. A push plate 18 is fixed to the top of the snap-fit post 1503. The end of the push plate 18 away from the snap-fit post 1503 passes through the limiting block 14 and is located outside the limiting block 14. One end of the 14 is provided with a moving groove 19 that matches the push plate 18. The outer walls of the locking post 1503 are fixed with second limiting blocks 16 at both ends. The inner walls of the limiting block 14 located in the inner cavity 1501 are provided with second limiting grooves 17 that match the second limiting blocks 16 at both ends. The inner walls of the protective sleeve 9 are fixed with first limiting blocks 11 at both ends. The inner walls of the connecting sleeve 7 are provided with first limiting grooves 12 that match the first limiting blocks 11 at both ends. The end of the protective sleeve 9 located outside the connecting sleeve 7 is fixed with a rubber ring 10.
[0019] The effect achieved by the entire embodiment 2 is that when it is necessary to disassemble the transparent protective cover 13, the user only needs to pull the two push plates 18 to drive the two locking posts 1503 to disengage from the transparent protective cover 13. At this time, the user can directly remove the transparent protective cover 13 and replace it. During installation, the locking posts 1503 only need to be pushed into the transparent protective cover 13 by the reset force of the second spring 1502, and then the transparent protective cover 13 is installed by the limiting of the four limiting blocks 14. By setting the first limiting block 11 and the first limiting groove 12, the distance of movement of the protective sleeve 9 can be limited to prevent it from accidentally moving out of the connecting sleeve 7. By setting the rubber ring 10, because the overall length of the rubber ring 10 is relatively long, it can deform to a certain extent according to the shape of the pipe. The alarm body 1, display 2, sensor 3, outlet 4, buzzer alarm light 5 and indicator light 6 of this device are all existing known structures, and no changes have been made to the internal electronic components of the body.
[0020] Working Principle: When in use, the device, through the connection sleeve 7 and protective sleeve 9, moves towards the pipe under the force of the first spring 8 when the sensor 3 is connected to the pipe, thus covering the connection point between the pipe and the sensor 3. This directly prevents external wind from entering through the connection point and causing damage, resulting in greater stability. Furthermore, the transparent protective cover 13 directly protects the display 2 from impacts, significantly increasing its lifespan and practicality. To remove the transparent protective cover 13, the user simply pulls the two push plates 18, causing the two... The locking post 1503 detaches from the transparent protective cover 13, at which point the user can directly remove the transparent protective cover 13 for replacement. During installation, the locking post 1503 is simply pushed into the transparent protective cover 13 by the reset force of the second spring 1502, and then the transparent protective cover 13 is installed by the limiting of the four limiting blocks 14. The first limiting block 11 and the first limiting groove 12 limit the distance of movement of the protective sleeve 9, preventing it from accidentally moving out of the connecting sleeve 7. The rubber ring 10 is relatively long and can deform to a certain extent according to the shape of the pipe.
[0021] The wiring diagrams for the alarm body 1, display 2, sensor 3, cable outlet 4, buzzer alarm light 5, and indicator light 6 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the alarm body 1, display 2, sensor 3, cable outlet 4, buzzer alarm light 5, and indicator light 6 will not be explained in detail.
[0022] 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.
