[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model: an alarm protection component, including:

[0025] A positioning component 1, the positioning component 1 includes a positioning sleeve 11, the inside of the positioning sleeve 11 is threadedly connected with a first threaded rod 12 and a second threaded rod 13, one end of the first threaded rod 12 is fixedly connected with an extrusion plate 14, and one end of the second threaded rod 13 is fixedly connected with an abutting rod 15. Through the threaded connection of the first threaded rod 12 and the second threaded rod 13, the positions of the extrusion plate 14 and the abutting rod 15 can be adjusted. The upper edge or the lower edge of the protruding position on the outer wall of the flash lamp is squeezed and limited by the extrusion plate 14, and further the outer wall of the base of the flash lamp is squeezed and positioned by the abutting rod 15, so that the installation and positioning of the device can be realized, and the stability of its installation can be ensured. At the same time, the threaded adjustment can adapt to flash lamp bases with different diameters for installation;

[0026] An explosion-proof component 2, the explosion-proof component 2 includes a protective cover 21, a guide rod 22 and a third threaded rod 23 are inserted into the bottom end of the protective cover 21, and the guide rod 22 and the third threaded rod 23 are fixedly connected to the upper surface of the positioning sleeve 11. Through the up and down sliding of the protective cover 21, the flexible adjustment of its height can be realized, so that the device can effectively adapt to flash lamps with different heights for external covering protection.

[0027] Furthermore, three groups of threaded holes are evenly arranged on the circumference of the positioning sleeve 11, and there are two threaded holes in each group, one above the other. The first threaded rod 12 and the second threaded rod 13 are vertically distributed and connected to the threaded holes. Anti-slip rubber pads are provided at the ends of the pressing plate 14 and the abutting rod 15 away from the first threaded rod 12 and the second threaded rod 13. Anti-slip handles are provided at the other ends of the first threaded rod 12 and the second threaded rod 13. The setting of the anti-slip handles increases the friction force when contacting the hand, thereby improving the stability of its rotation. At the same time, the stability and smoothness of the rotation of the first threaded rod 12 or the second threaded rod 13 are improved.

[0028] Furthermore, guide holes are opened at the centers of the vertical ends at the bottom of the protective cover 21, and limiting rings are fixedly connected to the bottom edges of the guide holes. Limiting shafts are fixedly connected to the tops of the guide rod 22 and the third threaded rod 23, and the limiting shafts are in contact with and slide in the guide holes of the protective cover 21. The guide rod 22 is in contact with and slides on the limiting ring. Through the setting of this structure, the sliding of the protective cover 21 and the third threaded rod 23 plays a good guiding and limiting role.

[0029] Furthermore, the guide rod 22 and the third threaded rod 23 are both circumferentially distributed, and two guide rods 22 are arranged between adjacent third threaded rods 23. The diameter of the guide rod 22 is equal to the outer diameter of the third threaded rod 23. A nut 24 is externally threaded on the third threaded rod 23, and the nut 24 abuts against the lower surface of the protective cover 21. Through the threaded connection of the third threaded rod 23 and the nut 24, the connection height of the nut 24 can be adjusted, so that the nut 24 completes the auxiliary support for the protective cover 21, preventing it from falling, and enabling this structure to adapt to flashlights of different heights for covering and protection.

[0030] Working principle: The first threaded rod 12, the second threaded rod 13, and the nut 24 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all well-known prior arts to those skilled in the art, so they will not be elaborated here. When this utility model is in use, first, the height of the protective cover 21 is adjusted according to the height of the flashlight. Pull the protective cover 21 upward, and then, by rotating the nut 24, its position is adjusted to complete the auxiliary support for the protective cover 21, making it adapt to flashlights of different heights for adaptability adjustment. Then, the device is sleeved outside the flashlight. Further rotate the first threaded rod 12 so that the pressing plate 14 abuts against the upper and lower sides of the protruding edge of the flashlight. Further rotate the second threaded rod 13 so that the abutting rod 15 abuts against the outer wall of the flashlight base, and the installation and positioning of the protection component can be completed.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
