Description

Technical Field

[0001] The utility model relates to the technical field of gas detectors, in particular to a universal gas alarm detector base. Background Art

[0002] Gas detector technology is a device used to detect and monitor the concentration of specific gases in the environment. This technology usually includes one or more sensors that can detect the presence of harmful or flammable gases such as carbon monoxide, hydrogen sulfide, methane, etc. When the detected gas concentration exceeds the preset safety threshold, the device will sound an alarm to protect people's lives.

[0003] After searching, the patent document with Chinese patent announcement number CN218334462U discloses a waterproof detector base. When the waterproof function is needed, the protective cover can be installed on the ceiling through the connecting through hole, and then the protective cover and the base are detachably connected. At this time, the fourth waterproof fence fits tightly with the ceiling to play a waterproof role. The covering part covers the incoming line through hole, and the water on the ceiling will not directly drip into the incoming line through hole. A gap is left between the first waterproof fence and the covering part for the communication line to pass through, and a gap is also left between the second waterproof fence and the bottom of the accommodating chamber for the communication line to pass through. When the communication line passes from the incoming line slot to the incoming line through hole and out, the first waterproof fence and the second waterproof fence squeeze the communication line to make it twisted in an S shape. When water flows down along the communication line, it will not enter the incoming line through hole, but will drip onto the base at the S-shaped bend of the communication line, and then be discharged along the drainage through hole. The utility model has a simple structure, obvious waterproof effect, and the waterproof level can reach IPX3.

[0004] The beneficial effects in the above patent specification mention that "the utility model has a simple structure and beautiful appearance. When there is water on the ceiling, the water will not enter the interior of the detector from the line inlet hole along the communication line, and the waterproof effect is obvious." Although the above patent has an obvious waterproof effect, it cannot effectively protect the device during specific use. This causes the internal detector to be damaged when the device suffers an unexpected external impact, reducing the service life of the device. For this reason, a gas alarm universal detector base is proposed to solve the above problem. Utility Model Content

[0033] Reference Figure 1 , Figure 3 and Figure 4The other end of the support rod 9 is fixedly connected to an outer column 10, and the inner wall of the outer column 10 is slidably connected to an inner column 11. A spring 12 is arranged inside the outer column 10, and the spring 12 here is used to provide a reaction force so that it can offset the impact force from the outside. One end of the spring 12 is fixedly connected to one side of a limit block 13, and the other end of the spring 12 is fixedly connected to one side of the inner wall of the outer column 10. The limit block 13 here is mixed with the outer column 10 to support and fix the spring 12. The inner wall of the inner column 11 is fixedly connected to the limit block 13, and the outside of the limit block 13 is slidably connected to the inner wall of the outer column 10. The limit block 13 here is used to In order to prevent the inner column 11 from escaping from the sliding range of the outer column 10, the other end of the inner column 11 is rotatably connected to a slider 14, and the outer side walls of the two sliders 14 are slidably connected to an outer plate 15, and the outer side wall of the outer plate 15 is fixedly connected to the inner wall of the outer shell 2. One side of the inner plate 8 is fixedly connected to two springs 2 16. When the outer shell 2 is accidentally hit by the outside, the force is transmitted to the outer plate 15, and then continues to be transmitted inward, so that the support rod 9 rotates and drives the slider 14 to slide on the outer plate 15, and at the same time, the spring 1 12 and the spring 2 16 begin to contract, providing a reaction force, thereby offsetting the impact force from the outside, thereby protecting the device body 7.

[0034] The other ends of the two springs 16 are fixedly connected to the inner wall of the outer plate 15, and the inner wall of the mounting assembly is slidably connected with a fixing assembly. Compared with the traditional fixing method, the fixing assembly here is more stable, not easy to fall off and has a longer service life. The fixing assembly includes a nail shell 17, the outer part of the nail shell 17 is slidably connected to the inner wall of the side plate 5, and the inner wall of the nail shell 17 is threadedly connected with a screw 18. The nail shell 17 here supports and fixes the screw 18, and the top of the screw 18 is fixedly connected with a screw 19, and the bottom end of the screw 19 contacts the top of the nail shell 17. The outer top of the nail shell 17 is fixedly connected with a limiting ring 20. The limiting ring 20 here plays a limiting role, and the bottom end of the limiting ring 20 contacts the top of the side plate 5. The outer part of the screw 18 A sliding ring 21 is threadedly connected, and side rods 1 22 are rotatably connected on both sides of the sliding ring 21. The outside of the side rod 1 22 is slidably connected to the inner wall of the nail shell 17, and the other end of the side rod 1 22 is rotatably connected to the side rod 23. The screw 19 is turned here to drive the screw column 18 to rotate, thereby driving the sliding ring 21 to slide down, so that the side rods 1 22 and the side rods 23 are rotated and expanded outward until they are tightly pressed against the inner wall of the wall, so as to achieve the purpose of stabilizing this device. The outside of the side rod 23 is slidably connected to the inner wall of the nail shell 17, and the bottom end of the screw column 18 is fixedly connected to the cone bottom 24, and the top end of the cone bottom 24 contacts the bottom end of the nail shell 17. The cone bottom 24 here makes it easier for the staff to use this fixing component to break the wall, saving installation time.

[0035] Working principle: When the staff is installing this gas alarm universal detector base, they can first press the base 1 and the side panel 5 against the wall to be installed, and then insert multiple nail shells 17 into the inner wall of the side panel 5. At this time, they can first use a hammer to use the cone tip of the cone bottom 24 to hammer the nail shell 17 into the wall until the limit ring 20 is close to the top of the side panel 5, and then use a screwdriver to tighten the screw 19. At this time, the screw 19 will drive the screw column 18 to rotate, so that the screw column 18 drives the sliding ring 21 to rotate, so that the sliding ring 21 will drive the side rod 1 22 and the side rod 2 23 to bend and expand outward, and squeeze more tightly against the inside of the wall to prevent accidental falling off, thereby enhancing the stability of the device.

[0036] When impacted by the outside, the outer shell 2 and the outer plate 15 here are first subjected to force, and then the force is transmitted to the spring 2 16, causing it to contract, and at the same time causing the support rod 9 on the inner plate 8 to start to rotate, and will rotate with the outer column 10 and the inner column 11, and at the same time causing the slider 14 to slide to both sides. At this time, the inner column 11 will squeeze the limit block 13, causing the spring 12 to start to contract, and at the same time, with the cooperation of the spring 2 16, it will emit a reaction force outward, thereby offsetting the impact force from the outside, thereby protecting the device body 7 inside the outer shell 2, to ensure that the device body 7 can operate normally, and to alarm when it detects high-risk gas.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
