[0025] Embodiment

[0026] Please refer to Figures 1 to 9 , in this embodiment, a weak current engineering safety alarm device is provided, including a mounting plate 1 and an alarm body 3. Fixed holes are provided at the four corners of the mounting plate 1, and it can be fixedly installed on other objects through fasteners such as bolts to achieve position fixation. Then, a connecting seat 2 is provided at the front end of the mounting plate 1, and the connecting seat 2 is snap-connected to the alarm body 3. The snap-connection fixation method enables the alarm body 3 to be easily disassembled, facilitating its maintenance or other operations. Moreover, a shaft rod 31 is provided at the rear end of the alarm body 3, and a clamping plate 32 is provided at the rear side of the shaft rod 31. The shaft rod 31 is placed in the connecting seat 2 and the clamping plate 32 is snap-connected with the connecting seat 2 for limit. By providing the shaft rod 31 and the clamping plate 32 on the alarm body 3, it realizes snap-connection fixation with the internal structure of the connecting seat 2 and is also convenient to remove;

[0027] Among them, the specific structure of the connecting seat 2 is as follows: it includes a base 21, the rear side of the base 21 is fixedly connected to the mounting plate 1, an upper cover 22 is provided at its front end, a slot 23 is opened on the front side wall of the upper cover 22, the center of the slot 23 is a circular hole, and the left and right sides of the circular hole are long strip-shaped grooves. The structure of the slot 23 corresponds to the shaft rod 31 and the clamping plate 32, and the two can be adapted. Moreover, a placement cavity is provided between the front inner wall of the upper cover 22 and the base 21. The shaft rod 31 and the clamping plate 32 are both placed in the placement cavity. During installation, the clamping plate 32 first corresponds to the long strip-shaped grooves on both sides of the slot 23, and then the alarm body 3 is pressed backward, that is, into the placement cavity. The shaft rod 31 and the clamping plate 32 are both pressed into the placement cavity, and then rotated. Finally, the internal structure of the connecting seat 2 realizes the limit of the clamping plate 32;

[0028] Chutes 24 are provided on both the left and right sides inside the base 21. Sliders 25 are provided in the chutes 24 and can slide within the chutes 24. Moreover, the chutes 24 and the slots 23 are perpendicular to each other in the front view direction. A plurality of springs 26 are provided at the rear end of the slider 25, and both ends of the springs 26 are respectively connected to the slider 25 and the rear end wall of the chute 24 to exert a squeezing and pushing force on the slider 25:

[0029] Under the action of the spring 26, without external force, the slider 25 will move forward, and its front end extends out of the chute 24 and contacts the inner wall of the upper cover 22. Thus, the slider 25 can limit and hold the clamping plate 32 installed in the placement cavity. When the clamping plate 32 is installed, after it is inserted into the slot 23 and pressed backward, the clamping plate 32 can press the slider 25, and the slider 25 is squeezed into the chute 24 and compresses the spring 26. The thickness of the clamping plate 32 is the same as the cavity width of the placement cavity. Furthermore, the clamping plate 32 can be limited in the front and rear directions in the placement cavity. After pressing in place, rotate the alarm body 3, so that the clamping plate 32 moves together with it, and rotate it 90 degrees clockwise or counterclockwise, so that the clamping plate 32 is perpendicular to the horizontal slot 23, realizing the limit of the upper cover 22 on the clamping plate 32;

[0030] After the clamping plate 32 is vertical, the pressing force on the slider 25 will disappear. At this time, the slider 25 will move forward under the action of the spring 26 until it abuts against the upper cover 22. After the slider 25 moves, the two sliders 25 on the left and right sides will limit the clamping plate 32. The upper and lower ends of the two sliders 25 will contact the clamping plate 32 to clamp the clamping plate 32, thereby realizing the limit and fixation of the clamping plate 32, and also realizing the clamping fixation of the alarm body 3;

[0031] To facilitate the removal of the clamping plate 32 from the placement cavity, that is, to facilitate the disassembly of the alarm body 3, a through groove 29 is provided inside the base 21. The through groove 29 is in a "T" shape. The horizontal groove at its top communicates with the chutes 24 on both sides, and its lower longitudinal groove penetrates the base 21. The horizontal groove and the longitudinal groove combine to form the "T" - shaped through groove 29. At the same time, the edges and side walls of the through groove 29 are all smooth - treated and are all smooth surfaces to avoid damaging the pull rope 27 inside it. A pull rope 27 adapted to it is provided in the through groove 29. The upper part of the pull rope 27 is located in the horizontal groove and has two connecting heads, which are respectively connected and fixed to the two sliders 25. Its bottom is located in the longitudinal groove and extends out of the base 21. A pull ring 28 is connected to the bottom of the pull rope 27. After pulling the pull ring 28, it will act on the pull rope 27. After the pull rope 27 is pulled, it is gradually pulled out of the through groove 29 and moves downward. At this time, the movement of the pull rope 27 will pull the slider 25, causing the slider 25 to retract into the chute 24. At this time, the slider 25 will not affect the clamping plate 32. Rotate the clamping plate 32 again to make it flush with the slot 23, and then pull out the alarm body 3 to achieve its disassembly.

[0032] In the present utility model, a clamping plate 32 is arranged at the rear side of the alarm body 3, which interacts with the upper cover 22 and the slider 25 in the connecting seat 2. Under the combined action of the spring 26 and the pull rope 27, the alarm can be clamped and fixed by pressing and then rotating, and the alarm can be disassembled by pulling the pull ring 28. The operation is convenient and fast, which is beneficial to the maintenance or other operations of the alarm, and has good practicability.

[0033] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, shall be implemented according to the conventional means in the art.
