Description

Technical Field

[0001] The utility model relates to the technical field of gas alarms, in particular to a gas alarm for a gas pipeline. Background Technique

[0002] A gas alarm is a gas leakage detection and alarm instrument. When gas leaks in a gas pipeline and the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the gas alarm will send out an alarm signal to remind the staff to take safety measures. The Chinese authorized utility model patent (Publication No.: CN221304065U) discloses a gas leakage automatic alarm device. By movably clamping the alarm housing on the gas pipeline, while being convenient for disassembly and assembly, it can quickly detect and alarm gas leakage in the first time, effectively shortening the response time of gas leakage alarm.

[0003] However, the above device still has some deficiencies in use: specifically, the alarm housing in the device is fixedly connected to the limit block. During the use process, when the gas alarm needs to be replaced due to a fault, the whole device is often replaced together, and it is difficult to effectively reuse the relevant structures such as the limit block for clamping on the pipeline. In summary, there is a lack of a design in the prior art that can efficiently separate the alarm housing from the limit plate, making the structures such as the limit plate unable to be reused after the gas alarm is replaced. Therefore, in view of the above situation, a gas alarm for a gas pipeline is proposed. Content of the Utility Model

[0004] The gas alarm for a gas pipeline proposed by the utility model has the advantages that the disassembly of the gas alarm housing is simple, and the installation components can continue to be used after the gas alarm is replaced.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figures 1-4 , a gas alarm for a gas pipeline, including a gas alarm housing 1 and a gas pipeline 2. An installation component 3 is provided at the bottom of the gas alarm housing 1. The installation component 3 includes a base 4, an assembly block 6 and a clamping plate 8. An inner cavity 401 is opened at the bottom of the base 4, and a rectangular groove 402 is opened at the top of the base 4. The rectangular groove 402 communicates with the inner cavity 401, and the number of the rectangular grooves 402 is two.

[0028] Round holes are opened on the inner wall of the inner cavity 401, and a hollow hole is opened on one side of the outer wall of the base 4. The hollow hole communicates with the inner cavity 401.

[0029] A bidirectional screw 5 is rotatably fitted in the round hole. One end of the bidirectional screw 5 away from the round hole passes through the hollow hole, and a knob is fixedly connected to the passing end of the bidirectional screw 5.

[0030] The assembly block 6 is slidably fitted with the rectangular groove 402. The number of the assembly blocks 6 is two. Threaded holes with opposite thread directions are opened on the two assembly blocks 6. The two assembly blocks 6 are respectively threadedly fitted with the bidirectional screw 5 through the threaded holes. Clamping blocks 7 are fixedly connected to the bottoms of the two assembly blocks 6. The two clamping blocks 7 both pass through the inner cavity 401, and the passing ends of the two clamping blocks 7 are clamped and fitted with the gas pipeline 2.

[0031] Three columns of slots 601 are opened on the tops of the two assembly blocks 6, and the number of each column of slots 601 is two.

[0032] There are two clamping plates 8. Insertion rods 801 are provided at the bottoms of the two clamping plates 8. The number of the insertion rods 801 is two, and the two insertion rods 801 are inserted into one column of the slots 601.

[0033] The gas alarm housing 1 is placed on the top of the installation assembly 3, and the two clamping plates 8 are clamped and cooperated with the gas alarm housing 1.

[0034] In this embodiment, when in use, rotate the knob, so that the knob drives the bidirectional screw rod 5 to rotate. The rotation of the bidirectional screw rod 5 makes the two assembly blocks 6 move relatively synchronously, and then the two assembly blocks 6 approach, that is, the two clamping blocks 7 approach, to complete the clamping and fixing of the gas pipeline 2. At the same time, place the gas alarm housing 1 on the top of the base 4. As the two assembly blocks 6 approach, the two clamping plates 8 can approach to clamp and fix the gas alarm housing 1.

[0035] When in use, the clamping plate 8 can be lifted upward, and the insertion rod 801 is inserted into the corresponding two slots 601 to complete the installation of the clamping plate 8, so as to meet the clamping and fixing requirements of the gas alarm housing 1.

[0036] In this embodiment, as Figure 1 shown, a detection hole is provided on the outer wall of the gas alarm housing 1. A power cord and an alarm lamp are provided on the gas alarm housing 1. A display screen and a buzzer are provided on the side wall of the gas alarm housing 1. A detection mechanism is provided inside the gas alarm housing 1.

[0037] In this embodiment, the composition structure of the detection mechanism is a well-known technical means in existing gas alarms, and will not be elaborated here.

[0038] In this embodiment, as Figure 2 and Figure 3 shown, the clamping block 7 is a block with a rectangular shape. An arc-shaped groove is provided on the clamping block 7, and the arc-shaped groove cooperates with the gas pipeline 2.

[0039] In this embodiment, the arc-shaped groove can better fit the outer wall of the gas pipeline 2. An anti-slip rubber pad is provided on the arc-shaped groove, which can further increase the friction with the pipeline and improve the positioning effect.

[0040] In this embodiment, as Figure 2 and Figure 4 shown, a fixing plate is provided on one side wall of the base 4. There are two fixing plates, and positioning components 9 are provided on both of the two fixing plates.

[0041] In this embodiment, the positioning component 9 includes an internally threaded cylinder. A threaded rod is threadedly connected to the internally threaded cylinder. A suction cup is fixedly connected to the end of the threaded rod. The suction cup adsorbs on the wall to fix the base 4 and prevent the base 4 from shaking.

[0042] In the above embodiments, the positioning component 9 is arranged on one side of the outer wall of the base 4 and is far away from the wall. Since it is far away from the wall, it is more convenient to operate, avoiding the problem in the prior art that the gas pipeline 2 is too close to the wall, resulting in inconvenient operation of the threaded rod.

[0043] In this embodiment, as Figure 2 and Figure 3 shown, the clamping plate 8 is a plate body with a rectangular shape, and a silica gel pad is arranged on the clamping plate 8.

[0044] In this embodiment, the setting of the silica gel pad can play a protective role for the gas alarm housing 1 when clamping the gas alarm housing 1.

[0045] In the above embodiments, the clamping plate 8 and the detection hole are not in the same plane. In order to be applicable to different alarms, the clamping plate 8 can be designed in a "mouth" shape, or ventilation holes can be designed on the clamping plate 8 to ensure that the leaked gas can smoothly enter the detection hole, and then the detection process can be completed.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
