Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please refer to the following: Figures 1 to 2 ,in, Figure 1 A schematic diagram of a preferred embodiment of the manual fire alarm button provided by this utility model; Figure 2 for Figure 1 The second perspective view of the structural schematic diagram shown. Figure 3 for Figure 1 The structural diagram shows part A, a cross-sectional view of the structure. It includes: base 1 and a symmetrical clamping mechanism.

[0016] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a base 1 is provided, and a housing 7 is placed on the base 1. One side of the housing 7 is attached to the inner wall of the base 1. An installation cavity 13 is provided inside the housing 7. An alarm 14 is fixedly installed in the installation cavity 13. A sliding groove 8 is provided on the surface of the base 1. A motor 9 is fixedly installed on one side of the groove wall inside the sliding groove 8. A bidirectional screw 10 is fixedly connected to the output shaft of the motor 9. One end of the bidirectional screw 10 is rotatably installed on the groove wall of the other side of the sliding groove 8. Clamping mechanisms are threaded on both sides of the bidirectional screw 10. The clamping mechanisms are used to clamp and fix the housing 7. The base 1 is L-shaped.

[0017] It should be noted that the motor 9 is preferably a servo motor. After the motor 9 is started, it can drive the bidirectional screw 10 to rotate and control the clamping mechanism on both sides of the bidirectional screw 10 to move towards each other and clamp and fix the housing 7, so that alarms 14 of different sizes can be quickly fixed and adapted.

[0018] refer to Figure 1 and Figure 2 As shown, protrusions 2 are fixedly installed on both sides of the base 1. A first threaded hole 3 is opened through the center of the protrusion 2. The base 1 is fixed to the wall by a fixing bolt 4 that is threadedly installed in the first threaded hole 3.

[0019] refer to Figure 1 and Figure 2 As shown, a smoke detector 5 is fixedly installed on the front of the base 1 near the top, and an alarm light 6 is fixedly installed on the top of the base 1. The smoke detector 5 and the alarm light 6 are electrically connected by wires.

[0020] It should be noted that when a fire occurs, the smoke detector 5 can sense the generated fire smoke and control the alarm light 6 to activate. The alarm light 6 will emit a bright colored light and a sharp alarm sound to remind people present of the location of the button.

[0021] refer to Figure 1 and Figure 2 As shown, the clamping mechanism includes symmetrical clamping blocks 11, which are slidably installed in the slide groove 8. A pad 12 is fixedly installed on the inner side wall of the symmetrical clamping blocks 11, and the pad 12 is made of rubber.

[0022] It should be noted that the rubber material is flexible and has good friction properties, which can greatly increase the friction between the rubber material and the contact surface of the housing 7, enhance the clamping stability, and at the same time avoid friction damage to the surface of the housing 7.

[0023] refer to Figure 1 and Figure 2As shown, slide rails 15 are fixedly installed on the top inner wall and bottom inner wall of the mounting cavity 13 near the front of the housing 7. A sliding mounting groove is opened through the side wall of the mounting cavity 13 adjacent to the bottom slide rail 15. A sliding baffle 16 is slidably installed in the sliding mounting groove, and the sliding baffle 16 is slidably installed between the two slide rails 15. A handle 17 is fixedly installed on the side wall of the sliding baffle 16.

[0024] It should be noted that pulling the handle 17 can control the sliding of the sliding baffle 16. When the button is not in use, the sliding baffle 16 can close the housing 7 to prevent external water and impurities from damaging the alarm 14.

[0025] refer to Figure 1 and Figure 3 As shown, a symmetrical mounting bracket 18 is fixedly installed on the top of the housing 7. A limiting screw 19 is threaded through and installed at the center of the top of the symmetrical mounting bracket 18. A second threaded hole 20 is opened through the slide rail 15 on the surface of the housing 7 below the limiting screw 19 and the top inner wall of the mounting cavity 13. The second threaded hole 20 communicates with the mounting cavity 13, and the limiting screw 19 is threadedly matched with the second threaded hole 20.

[0026] It should be noted that when the sliding baffle 16 closes the housing 7, the rotating limit screw 19 can drive the limit screw 19 downward through the second threaded hole 20 and tightly abut against the sliding baffle 16, further enhancing the sealing performance.

[0027] The working principle of the manual fire alarm button provided by this utility model is as follows: First, attach the base 1 to the wall and thread the two fixing bolts 4 through the first threaded holes 3 on both sides to the wall. After fixing, place the housing 7 to be used on the base 1, and make the side wall of the housing 7 fit against the inner wall of the base 1. At this time, start the motor 9 to control the rotation of the bidirectional screw 10, so that the clamping blocks 11 threaded on both sides of the bidirectional screw 10 move towards each other until the housing 7 is clamped and fixed. When the alarm is needed after fixing, turn the two limit bolts 19 to loosen the fixing of the sliding baffle 16, pull the handle 17 to pull out the sliding baffle 16, and then press the button on the alarm 14.

[0028] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model.
