[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 The utility model provides a technical solution: a portable combustible gas detection alarm, including a protective box body 1, an alarm body 12 is arranged inside the protective box body 1, a detection probe 14 is installed on the alarm body 12 through a conductive line 13, a box cover 2 is installed at one end of the protective box body 1 through a hinge 7, and a lock 3 is installed at the other end of the protective box body 1 and the box cover 2.

[0025] Furthermore, the outer side of the conductive line 13 is formed by a universal hose, which allows the conductive line 13 to be freely turned while maintaining a stable state, thereby ensuring a stable use state of the detection probe 14.

[0026] A limiting component for fixing the position of the alarm body 12 is provided in the protection box body 1 , and the alarm body 12 is hidden in the protection box body 1 through the limiting component.

[0027] Furthermore, the limiting assembly includes a clip 10 and a spring 11. The clip 10 is fixed in the protective box body 1 by the spring 11. The displacement of the clip 10 is controlled by the spring 11, and the clip 10 and the spring 11 are symmetrically arranged in the protective box body 1. The clip 10 is clamped and connected to both sides of the alarm body 12 by the spring 11 to ensure that the alarm body 12 is stable and safe in the protective box body 1.

[0028] Furthermore, the upper end of the clip 10 is configured to be convex, and the convex structure at the upper end of the clip 10 can clamp the alarm body 12 to prevent the alarm body 12 from moving, and the lower end of the clip 10 is in contact with the protective box body 1 to facilitate the free movement of the clip 10. It is noted here that the bending of the spring 11 itself must have a certain strength to prevent the clip 10 from moving upward, so as to ensure that the clip 10 can stably clamp the alarm body 12.

[0029] A clamping assembly for fixing the conductive wire 13 is provided in the box cover 2 , and the conductive wire 13 is arranged in a coiled shape in the box cover 2 through the clamping assembly.

[0030] Furthermore, the snap-on assembly includes a snap 6, which is fixedly arranged on the inner side of the box cover 2 and is located at the inner edge of the box cover 2. The conductive wire 13 can be fixed to the edge of the box cover 2, making rational use of space and avoiding compression contact between the conductive wire 13 and the alarm body 12 in the protective box body 1.

[0031] Furthermore, an open circular through groove is provided on the buckle 6 , and the inner diameter of the circular through groove on the buckle 6 is equal to the outer diameter of the conductive wire 13 , so as to facilitate the disassembly, assembly and fixation of the conductive wire 13 .

[0032] A pressing assembly for squeezing and fixing the alarm body 12 is provided in both the protective box body 1 and the box cover 2. The pressing assembly and the limiting assembly are staggered.

[0033] Furthermore, the clamping assembly includes a first spring piece 5 and a second spring piece 9. The first spring piece 5 is installed in the box cover 2 through the first clamping seat 4, and the first clamping seat 4 is fixedly connected to the box cover 2, which is convenient for disassembly and assembly of the first spring piece 5. The second spring piece 9 is installed in the protective box body 1 through the second clamping seat 8, and the second clamping seat 8 is fixedly connected to the protective box body 1, which is convenient for disassembly and assembly of the second spring piece 9.

[0034] Furthermore, the first spring piece 5 and the second spring piece 9 are both arc-shaped metal sheets, and the first spring piece 5 and the second spring piece 9 are in contact connection with the alarm body 12, ensuring a stable squeezing state of the alarm body 12 and improving the safety of the alarm body 12 in the protective box body 1 and the box cover 2.

[0035] Specifically, when using the portable combustible gas detection alarm, the alarm body 12 is first installed in the protective box body 1. The clip 10 in the protective box body 1 clamps the alarm body 12 under the action of the spring 11. At the same time, the bottom of the alarm body 12 contacts the second elastic piece 9, but the second elastic piece 9 does not squeeze the alarm body 12, but only plays a simple supporting role.

[0036] Then, the conductive wire 13 on the alarm body 12 is clipped onto the buckle 6 inside the box cover 2. At the same time, a certain length of the conductive wire 13 should be reserved at the front end of the alarm body 12 so that the conductive wire 13 will not be affected when the box cover 2 is flipped open and closed on the protective box body 1. Under the action of the buckle 6, the conductive wire 13 can be coiled inside the box cover 2, which also ensures the stability of the detection probe 14.

[0037] After the box cover 2 is closed, the first elastic piece 5 on the box cover 2 will press down the alarm body 12, and the second elastic piece 9 below the alarm body 12 will also squeeze the alarm body 12 to ensure that the alarm body 12 is stable and safe. Finally, the box cover 2 is closed. The box cover 2 and the protective box body 1 are fixed by the lock buckle 3, so that the alarm is box-shaped as a whole, which is convenient for carrying and using. When the box cover 2 is closed, the position of the detection probe 14 should be adjusted so that it is located in the neutral position and will not be squeezed and damaged when the box cover 2 is closed. At the same time, the buckle 6 can fix the conductive wire 13 to move. When the conductive wire 13 connected to the detection probe 14 is fixed on the buckle 6, the state of the detection probe 14 can also be maintained stable.

[0038] When the alarm is used, after the box cover 2 is opened, the first spring piece 5 releases the pressure on the alarm body 12, and the second spring piece 9 also restores the supporting effect on the alarm body 12, and does not apply an upward force to the alarm body 12, thereby ensuring that the alarm body 12 is stably clamped by the clamping piece 10 when the box cover 2 is opened;

[0039] After that, remove the conductive wire 13 and the detection probe 14 on the box cover 2, and then you can cooperate with the alarm body 12 to perform combustible gas detection work, or you can directly take out the alarm body 12 for use;

[0040] The above is the usage process of the alarm, and the contents not described in detail in this manual, such as the alarm body 12, the conductive wire 13, and the detection probe 14, are all existing technologies well known to professional and technical personnel in this field.

[0041] 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 scope of protection of the present invention.
