Description

Technical Field

[0001] This utility model relates to the field of gas leak detection technology, specifically a gas leak detector. Background Technology

[0002] Currently, most handheld gas leak detectors on the market have exposed detection heads. When workers are not using the handheld gas leak detector, they usually put it directly into their tool bag. When workers move around with their tool bags, the handheld gas leak detector is prone to colliding with other tools in the bag, which can damage the detection head. In order to address the above situation, we will innovate the technology based on the existing gas leak detectors. Utility Model Content

[0003] The purpose of this invention is to provide a gas leak detector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gas leak detector, comprising:

[0005] The gas leak detector body has a gas leak detection head electrically connected to its upper part, wherein:

[0006] The bottom of the gas leak detection head is provided with a mounting base, and a set of mounting grooves are provided on both the left and right sides of the mounting base. A spring is provided in the mounting groove, and a set of round-headed pins is provided on the opposite sides of the two sets of springs.

[0007] The sleeve has a set of protective plates on both its left and right sides. A first connecting seat is provided at the bottom of the protective plate. A through hole is provided on the front side of the first connecting seat. A rotating shaft is provided in the through hole. A torsion spring is provided between the rotating shaft and the through hole. A set of second connecting seats is provided on both the front and rear sides of the rotating shaft. The second connecting seats are provided on the outer wall of the sleeve.

[0008] Preferably, the sleeve is slidably fitted onto the outside of the mounting base and the gas leak detection head, with the gas leak detection head located between the two sets of protective plates.

[0009] Preferably, a first locking hole and a second locking hole are provided on both the left and right sides of the sleeve, with the second locking hole located above the first locking hole.

[0010] Preferably, the end of the round-headed pin furthest from the spring is inserted into the second locking hole, and the spring corresponds to the first locking hole.

[0011] Preferably, a flexible probe is provided at the bottom of the mounting base, and the main body of the gas leak detector is located at the bottom of the flexible probe.

[0012] Preferably, an elastic bracket is provided on the rear side of the main body of the gas leak detector, and the elastic bracket corresponds to the flexible probe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, when the gas leak detection head is idle, the round-headed pin is pressed to separate it from the second locking hole, and then the sleeve is slid upward. When the round-headed pin is aligned with the first locking hole, the spring drives the round-headed pin to insert into the first locking hole. At this time, the top of the sleeve is flush with the top of the gas leak detection head. At the same time, the torsion spring drives the protective plate to flip inward through the first connecting seat to seal the top of the sleeve and the gas leak detection head, thereby protecting the gas leak detection head and effectively improving its service life.

[0015] When the device is not in use, the flexible probe is bent and snapped into the elastic bracket, which reduces the size of the device and improves its convenience. 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 Figures 1-3A gas leak detector includes a main body 1 and a sleeve 2. A gas leak detection head 13 is electrically connected to the top of the main body 1. The main body 1 controls the operation of the gas leak detection head 13 to detect gas leaks in gas pipelines. The gas leak detection head 13 has a mounting base 4 fixedly installed at its bottom. Each side of the mounting base 4 has a set of mounting grooves, and springs 211 are fixedly installed in the mounting grooves. A set of round-headed pins 21 are fixedly installed on the opposite sides of the two sets of springs 211. Each side of the sleeve 2 has a set of protective plates 22, and a first connecting seat 221 is fixedly installed at the bottom of the protective plates 22. A through hole is provided on the front side of the first connecting seat 221. A rotating shaft 24 is rotatably installed inside the through hole. A torsion spring 25 is fixedly installed between the rotating shaft 24 and the through hole. A set of second connecting seats 23 are fixedly installed on both the front and rear sides of the rotating shaft 24. The second connecting seats 23 are fixedly installed on the outer wall of the sleeve 2. The sleeve 2 is slidably sleeved on the outside of the mounting seat 4 and the gas leak detection head 13. The gas leak detection head 13 is located between the two sets of protective plates 22. When the gas leak detection head 13 is in an idle state, the round head pin 21 is pressed to separate it from the second locking hole 31. Then the sleeve 2 is slid upward. When the round head pin 21 is aligned with the first locking hole 3, the spring 211 drives the round head pin 21 to insert into the first locking hole 3. At this time, The top of the sleeve 2 is flush with the top of the gas leak detection head 13. Simultaneously, the torsion spring 25, through the first connecting seat 221, causes the protective plate 22 to flip inward, sealing the tops of the sleeve 2 and the gas leak detection head 13, thus protecting the gas leak detection head 13. When the gas leak detection head 13 needs to be used, press the round-headed pin 21 to separate it from the first locking hole 3. Then, the sleeve 2 can be moved downwards first. When the sleeve 2 moves downwards, the gas leak detection head 13 will push open the two sets of protective plates 22. When the round-headed pin 21 aligns with the second locking hole 31, the spring 211 drives the round-headed pin 21 to insert into the second locking hole 31, thus completing the fixing of the sleeve 2, and allowing the gas leak detection head to be used normally. 13. A set of first locking holes 3 and a set of second locking holes 31 are provided on both the left and right sides of the sleeve 2. The second locking holes 31 are located above the first locking holes 3. The end of the round-headed pin 21 away from the spring 211 is inserted into the second locking hole 31. The spring 211 corresponds to the first locking hole 3. A flexible probe 12 is fixedly provided at the bottom of the mounting base 4. The gas leak detector body 1 is located at the bottom of the flexible probe 12. An elastic bracket 11 is fixedly provided on the rear side of the gas leak detector body 1. The elastic bracket 11 corresponds to the flexible probe 12. When the device is idle, the flexible probe 12 is bent and clipped onto the elastic bracket 11, which can reduce the size of the device and improve its convenience.

[0022] Working principle: The gas leak detector body 1 controls the gas leak detection head 13 to work, detecting gas leaks in the gas pipeline. When the gas leak detection head 13 is idle, the round-headed pin 21 is pressed to separate it from the second locking hole 31. Then, the sleeve 2 is slid upwards. When the round-headed pin 21 is aligned with the first locking hole 3, the spring 211 drives the round-headed pin 21 to insert into the first locking hole 3. At this time, the top of the sleeve 2 is flush with the top of the gas leak detection head 13. Simultaneously, the torsion spring 25 drives the protective plate 22 to flip inward through the first connecting seat 221, sealing the top of the sleeve 2 and the gas leak detection head 13. This device protects the gas leak detection head 13. When the gas leak detection head 13 needs to be used, press the round head pin 21 to separate it from the first locking hole 3. Then, the sleeve 2 can be moved down first. When the sleeve 2 moves down first, the gas leak detection head 13 will push open the two sets of protective plates 22. When the round head pin 21 is aligned with the second locking hole 31, the spring 211 drives the round head pin 21 to insert into the second locking hole 31, thus completing the fixing of the sleeve 2. Then the gas leak detection head 13 can be used normally. When the device is not in use, the flexible probe 12 can be bent and clipped onto the elastic seat 11, thus reducing the size of the device and improving its convenience.
