Description

Technical Field

[0001] This utility model belongs to the field of alarm button technology, specifically relating to manual fire alarm buttons. Background Technology

[0002] Manual fire alarm buttons are installed in prominent locations in public places. When personnel confirm that a fire has occurred, they can activate the button to send an alarm signal to the controller in the control room. The controller can then display the location of the alarm button and trigger audible and visual alarms to issue fire warnings and remind personnel to evacuate quickly.

[0003] However, existing manual fire alarm buttons have many parts, making assembly complex and inconvenient. Furthermore, existing manual fire alarm buttons only use tactile switches as triggers, with the active end of the tactile switch exposed to the air. However, dust, moisture, and salt in the environment can negatively affect the tactile switch, especially in humid southern cities. This is mainly because the positive and negative metal contacts of the tactile switch are close together. When the air contains high levels of moisture and salt, air discharge can easily occur between the two contacts. Over time, the tactile switch will corrode and be damaged, causing the manual fire alarm button to malfunction.

[0004] Therefore, in order to address the above shortcomings, it is still necessary to improve the existing manual fire alarm buttons. Utility Model Content

[0005] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a manual fire alarm button.

[0006] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A manual fire alarm button includes a base with L-shaped mounting seats on its four sides. A central plate is installed inside the base, and mounting slots are provided on the four sides of the central plate at corresponding mounting seats. The top of the mounting seats is located within the mounting slots. A circuit board is installed on the inner top of the central plate, and a tactile switch, a vertical push switch, and a photoelectric switch are installed on the circuit board. A light shield is also installed on the top of the central plate, positioned above the photoelectric switch. A rotary groove is provided on the other side of the top of the central plate, and a spring arm is movably connected to the central plate through the rotary groove. An operation panel is installed on the other side of the spring arm, positioned above the circuit board. A tactile pressure plate is provided at the bottom of the operation panel at the corresponding tactile switch, and a silicone protective sleeve is installed at the bottom of the operation panel at the corresponding vertical push switch, covering the outside of the vertical push switch. An indicator light is also provided on the operation panel at the corresponding photoelectric switch. An upper shell is provided on the outside of the operation panel, installed inside the base, and a through-hole groove is provided on the upper shell at the corresponding operation panel.

[0008] Furthermore, the base has several evenly arranged mounting slots on its inner bottom side, and spring clips are installed in these slots by screws. This structural design facilitates fixed connection with external telephone lines and bus lines.

[0009] Furthermore, the upper shell has limiting grooves on all four sides, and the inner top of the base has limiting buckles at the corresponding limiting grooves. This structural design facilitates a secure fastening connection between the upper shell and the base.

[0010] Furthermore, the upper shell is equipped with several ribs, the bottom of which presses against the outer side of the middle plate. This structural design, after installation, uses the pressing of the ribs to limit the position of the middle plate, improving the fixing effect and preventing it from shaking.

[0011] Furthermore, the bottom of the silicone protective sleeve is installed on the circuit board in a sealed state. This structural design achieves a sealed installation effect, protects the vertical push switch, and extends its service life.

[0012] The beneficial effects of this utility model are as follows: When in use, this utility model can simultaneously realize three switching methods: tactile switch, vertical push switch and photoelectric switch, preventing the switch from being corroded and damaged, causing the manual fire alarm button to malfunction. In addition, this utility model has fewer parts and lower cost. The parts are basically stacked in a pyramid-like manner, and the assembly is mostly done by pressing from top to bottom, which requires less force and is simple and easy to assemble.

Detailed Implementation

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1, such as Figure 1 , Figure 2 and Figure 3As shown, the manual fire alarm button has an L-shaped mounting base 2 installed on the four sides of the base 1. A middle plate 3 is installed inside the base 1. The four sides of the middle plate 3 have mounting grooves 4 corresponding to the mounting base 2. The top of the mounting base 2 is located within the mounting grooves 4. A circuit board 5 is installed on the inner top of the middle plate 3. A tactile switch 6, a vertical push switch 7, and a photoelectric switch 8 are installed on the circuit board 5. A light shield 9 is also installed on the top of the middle plate 3, positioned above the photoelectric switch 8. A rotary latch groove 10 is also provided on the other side of the top of the middle plate 3, through which the middle plate 3 is movably connected to... A spring arm 11 is provided, and an operation panel 12 is installed on the other side of the spring arm 11. The operation panel 12 is located on the upper side of the circuit board 5. A tactile pressure plate 13 is provided at the bottom of the operation panel 12 corresponding to the tactile switch 6. A silicone protective sleeve 14 is installed at the bottom of the operation panel 12 corresponding to the vertical push switch 7. The silicone protective sleeve 14 is fitted on the outside of the vertical push switch 7. An indicator light 15 is also provided at the corresponding photoelectric switch 8 of the operation panel 12. An upper shell 16 is provided on the outside of the operation panel 12. The upper shell 16 is installed in the base 1. A through hole groove 161 is provided on the upper shell 16 corresponding to the operation panel 12.

[0023] In this embodiment, during assembly, the middle plate 3 is first installed into the base 1, so that the mounting slots 4 on the four sides of the middle plate 3 are installed on the top of the mounting base 2 for positioning. Then, the circuit board 5 containing the tactile switch 6, the vertical push switch 7, and the photoelectric switch 8 is installed onto the middle plate 3. Next, the light shield 9 is installed onto the middle plate 3, positioned on top of the photoelectric switch 8. The middle plate 3 is connected to the spring arm 11 through the snap-lock slot 10, so that the spring arm 11 drives the operation panel 12 to be placed on the circuit board 5. Finally, the upper shell 16 is covered to complete the assembly.

[0024] When in use, three switching modes can be implemented simultaneously: tactile switch 6, vertical push switch 7, and photoelectric switch 8.

[0025] When using the tactile switch 6, simply touch the operation panel 12, and the tactile pressure plate 13 on the other side of the operation panel 12 will push the tactile switch 6 to open, thereby enabling operation;

[0026] When the vertical push switch 7 is used, the operation panel 12 is pressed through the through hole groove 161 of the upper shell 16, causing the operation panel 12 to drive the spring arm 11 to rotate on the snap groove 10, thereby causing the operation panel 12 to push the silicone protective cover 14, and the silicone protective cover 14 to push the vertical push switch 7 to open, thus enabling the operation.

[0027] The operation panel 12 can also achieve the reset spring force through the deformation of the spring arm 11, eliminating the need for a spring.

[0028] When using photoelectric switch 8, the two indicator lights 15 on the operation panel 12 achieve light transmission by locally thinning the wall thickness, eliminating the need for lamp posts and light guides. Furthermore, a light-blocking triggering method is adopted. Within the set detection range, the photoelectric switch 8 will only generate a switching signal when the amount of light reflected back by the object is sufficient. Background light exceeding this set range will not be recognized as a valid signal, thereby avoiding malfunctions.

[0029] Example 2, as Figure 2 and Figure 5 As shown, this embodiment adds the following structure to the embodiment 1: the bottom inner side of the base 1 is provided with several evenly arranged mounting grooves 17, and spring pieces 18 are installed in the mounting grooves 17 by screws.

[0030] In this embodiment, during the assembly process, the spring 18 is locked in the mounting slot 17 by screws, and at the same time, it presses the external telephone line and bus connected to the outside to prevent them from loosening and affecting use.

[0031] Example 3, as Figure 2 , Figure 3 and Figure 5 As shown, this embodiment adds the following structure to the embodiment 1: the upper shell 16 is provided with limiting grooves 19 on its four sides, and the inner top of the base 1 is provided with limiting buckles 20 at the corresponding limiting grooves 19.

[0032] In this embodiment, when installing the upper shell 16, the upper shell 16 is first inserted into the base 1, so that the limiting groove 19 on the outer side of the upper shell 16 is engaged into the limiting buckle 20, thereby positioning and connecting the upper shell 16 with the base 1.

[0033] In order to further increase the stability of the installation, after the upper shell 16 is connected to the limiting buckle 20 through the limiting groove 19, the lower buckle 22 is provided on the four sides inside the upper shell 16. When the upper shell 16 is installed into the base 1, the upper shell 16 will drive the lower buckle 22 to move downward, so that the lower buckle 22 passes through the middle plate 3 and is locked at the bottom of the middle plate 3, thereby cooperating with the connection between the external limiting groove 19 and the limiting buckle 20 to further improve the installation and fixation effect.

[0034] Example 4, as Figure 3 As shown, this embodiment adds the following structure based on embodiment 1: the upper shell 16 is provided with several bone beams 21, and the bottom of the bone beams 21 is pressed against the outside of the middle plate 3.

[0035] In this embodiment, during installation, the upper shell 16 is connected to the limiting buckle 20 through the limiting groove 19, and the lower buckle 22 is fixedly installed at the bottom of the middle plate 3. Furthermore, the bottom of the inner bone beam 21 is pressed against the top outer side of the middle plate 3, which further limits and fixes the middle plate 3 to prevent it from shaking.

[0036] Example 5, as Figure 2 As shown, this embodiment adds the following structure to the embodiment 1: the bottom of the silicone protective sleeve 14 is installed on the circuit board 5 in a sealed state.

[0037] In this embodiment, the silicone protective sleeve 14, which is installed in a sealed state, can protect the vertical push switch 7 during use, preventing moisture and salt from affecting the vertical push switch 7 and extending its service life.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
