Description

Technical Field

[0001] This utility model relates to the field of sound and light alarm technology, specifically an explosion-proof sound and light alarm. Background Technology

[0002] An alarm device is a device that issues alarm signals. It is used to issue warning, alarm, and all-clear signals. Among them, the explosion-proof audible and visual alarm device is an audible and visual alarm device installed on site. When an accident or fire occurs at the production site and an audible and visual alarm is required, the explosion-proof audible and visual alarm device is activated by a control signal. The device can then issue sound and light alarm signals to achieve the purpose of alarm notification.

[0003] The prior art, disclosed in CN222233092U, provides an explosion-proof audible and visual alarm, including a mounting base, an explosion-proof audible and visual alarm body, and a push button. A limiting straight slide groove is formed in the middle of the lower end face of the mounting base. A slide rod is fixedly connected to the bottom surface behind the limiting straight slide groove. A slider is sleeved on the outer curved surface of the front end of the slide rod, and a main spring is sleeved on the outer curved surface of the rear end of the slide rod. An installation slide groove is formed on the side of the middle of the front end face of the mounting base. A square pin hole is formed on the side wall of the installation slide groove. A square pin block is inserted into the inner wall of the square pin hole. A secondary spring is fixedly connected to the side of the square pin block away from the limiting straight slide groove. Four installation opening slots are formed at the four corners of the lower end face of the mounting base, symmetrically distributed around the four corners. This utility model facilitates both disassembly and reinstallation of the explosion-proof audible and visual alarm body.

[0004] The aforementioned patent primarily utilizes the cooperation of a secondary spring and a main spring to facilitate the disassembly of the explosion-proof audible and visual alarm. However, this method of disassembling the alarm relies on the spring's rebound force. This can lead to a significant rebound force being released the moment the main spring loses its compressive force, causing the alarm to move outwards. If the user fails to catch the alarm, it may fall, eventually damaging its outer surface and reducing its practicality. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an explosion-proof audible and visual alarm, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof audible and visual alarm, comprising an installation assembly, a connecting assembly fixedly mounted at the center of the installation assembly, and an explosion-proof audible and visual alarm body detachably mounted at the end of the connecting assembly away from the installation assembly. The connecting assembly includes a fixing plate fixedly mounted on the explosion-proof audible and visual alarm body, and a T-shaped plate fixedly mounted at the center of the end of the fixing plate away from the explosion-proof audible and visual alarm body. The installation assembly includes an installation plate, and a locking assembly fixedly mounted at the end of the installation plate near the explosion-proof audible and visual alarm body.

A movable groove for the movement of the top horizontal plate of the T-shaped plate is opened on the side of the trapezoidal ring shaft near the top plate. A through groove is opened through the center of the trapezoidal ring shaft, which is adapted to the horizontal plate of the T-shaped plate. A fixing groove is opened on the side of the trapezoidal ring shaft away from the top plate on the movable groove. The fixing groove is adapted to the horizontal plate of the T-shaped plate and is used for the fixed installation of the T-shaped plate.

[0008] Furthermore, an elastic component is fixedly installed at one end of the top plate near the body of the explosion-proof audible and visual alarm, the elastic component being used to elastically fix the T-shaped plate in the fixing groove.

[0009] Furthermore, the elastic component includes an adhesive plate fixedly mounted on the top plate. A spring is fixedly mounted on the end of the adhesive plate away from the top plate. A telescopic shaft is fixedly mounted at the center of the end of the adhesive plate away from the top plate, and the telescopic shaft is located inside the spring. A push plate is fixedly mounted on the end of the telescopic shaft away from the adhesive plate, and the spring is fixedly mounted on the push plate. The spring's fixed mounting on the push plate makes the internal structure of the explosion-proof audible and visual alarm more robust and reliable, improving the operational stability of the explosion-proof audible and visual alarm.

[0010] Furthermore, the mounting plate has fixing holes at its four corners, allowing it to be securely installed to the wall. This installation method enhances the ease of installation for the explosion-proof audible and visual alarm.

[0011] Furthermore, curved plates are fixedly installed on both sides of the fixed plate away from the T-shaped plate. Bolts are movably installed on the curved plates, and the curved plates are fixedly installed to the explosion-proof audible and visual alarm body by bolts. The fixed installation of the curved plates to the explosion-proof audible and visual alarm body by bolts makes the internal structure of the explosion-proof audible and visual alarm more robust and reliable, and improves the safety of the explosion-proof audible and visual alarm operation.

[0012] Furthermore, the connection between the penetrating groove and the fixing groove forms a cross. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention fixes the explosion-proof audible and visual alarm body onto the connecting assembly. When the explosion-proof audible and visual alarm body, together with the connecting assembly, needs to be installed onto the mounting assembly, the user needs to insert the T-shaped plate into the penetration groove, allowing the T-shaped plate to rotate within the movable groove. When the T-shaped plate rotates to the fixed groove position, the user no longer applies force, and the spring pulls the T-shaped plate into the fixed groove for installation. This requires the user to continuously drag the explosion-proof audible and visual alarm body during installation, preventing it from falling off during loading and unloading, thus improving the practicality of the explosion-proof audible and visual alarm.

The connecting assembly 2 includes a fixing plate 23 fixedly mounted on the explosion-proof audible and visual alarm body 3. A T-shaped plate 24 is fixedly mounted at the center of the end of the fixing plate 23 away from the explosion-proof audible and visual alarm body 3. The mounting assembly 1 includes a mounting plate 13. A locking assembly 11 is fixedly mounted on the end of the mounting plate 13 near the explosion-proof audible and visual alarm body 3. The locking assembly 11 is used to cooperate with the T-shaped plate 24 to mount the explosion-proof audible and visual alarm body. 3. Mounting assembly 1 is used for the safe installation and removal of the explosion-proof audible and visual alarm body 3. The locking assembly 11 includes a trapezoidal ring shaft 111 fixedly mounted on the mounting plate 13. A top plate 116 is fixedly mounted on the side of the trapezoidal ring shaft 111 away from the explosion-proof audible and visual alarm body 3. The top plate 116 is flush with the side of the mounting plate 13 away from the explosion-proof audible and visual alarm body 3. A movable groove 114 for the movement of the top horizontal plate of the T-shaped plate 24 is opened on the side of the trapezoidal ring shaft 111 near the top plate 116. A through groove 113 is opened through the center of the trapezoidal ring shaft 111. The through groove 113 is adapted to the horizontal plate of the T-shaped plate 24. The trapezoidal ring shaft 111 moves in the direction of movement. A fixing groove 112 is provided on the side of the groove 114 away from the top plate 116. The fixing groove 112 is adapted to the cross plate of the T-shaped plate 24 and is used for the fixed installation of the T-shaped plate 24. An elastic component 115 is fixedly installed on the end of the top plate 116 near the explosion-proof sound and light alarm body 3. The elastic component 115 is used to elastically fix the T-shaped plate 24 in the fixing groove 112. The elastic component 115 includes an adhesive plate 1151 fixedly installed on the top plate 116. A spring 1154 is fixedly installed on the end of the adhesive plate 1151 away from the top plate 116. A telescopic component is fixedly installed at the center of the end of the adhesive plate 1151 away from the top plate 116. The telescopic shaft 1152 is located inside the spring 1154. A push plate 1153 is fixedly installed on the end of the telescopic shaft 1152 away from the adhesive plate 1151. The spring 1154 is fixedly installed on the push plate 1153. Fixing holes 12 are opened on the four corners of the mounting plate 13. The mounting plate 13 is fixedly installed to the wall through the fixing holes 12. Arc plates 21 are fixedly installed on both sides of the side of the fixing plate 23 away from the T-shaped plate 24. Bolts 22 are movably installed on the arc plates 21. The arc plates 21 are fixedly installed to the explosion-proof sound and light alarm body 3 through the bolts 22. The connection between the through groove 113 and the fixing groove 112 forms a cross.

[0018] Since the size of the horizontal plate of the T-shaped plate 24 is compatible with the through slot 113 and the fixing slot 112, the user can easily insert the T-shaped plate 24 into the through slot 113 and fix the explosion-proof sound and light alarm by moving the horizontal plate of the T-shaped plate 24 into the fixing slot 112.

[0019] Among them, the explosion-proof audible and visual alarm body 3 is model JDSG-2. The explosion-proof fire audible and visual alarm is a non-coded alarm, which is suitable for installation in explosive gas environments containing Class IIC T6 temperature group. Its working principle is as follows: when an accident or fire occurs at the production site, the control signal sent by the fire alarm controller activates the audible and visual alarm circuit, and emits sound and light alarm signals to achieve the alarm purpose. The alarm can also be used in conjunction with a manual alarm button to achieve a simple sound and light alarm purpose. The alarm can be used with fire alarm controllers from any manufacturer at home and abroad. The alarm uses ultra-bright LED light-emitting tubes, which are clearly visible from 360 degrees. Since the explosion-proof audible and visual alarm body 3 is a common existing device, this utility model has not been described in detail.

[0020] Among them, the outer shell of the explosion-proof sound and light alarm body 3 is made of ZL102 aluminum alloy die casting and the surface is high-pressure electrostatic powder coating.

[0021] Among them, the explosion-proof sound and light alarm body 3 is a tempered glass cover with exposed stainless steel fasteners, and the protective mesh cover is galvanized and then powder-coated for double corrosion protection.

[0022] Among them, the tempered glass cover of the explosion-proof sound and light alarm body 3 has strong impact resistance and is available in a variety of colors such as red, yellow, and blue.

[0023] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the explosion-proof audible and visual alarm are fixed by threads. To allow for a more intuitive observation of the technical features, the bolt connections are appropriately concealed in the figures. The mounting plate 13 inside the explosion-proof audible and visual alarm body 3 is bolted to the wall or ceiling. Since the elastic component 115 is fixedly installed on the top plate 116, when the T-shaped plate 24 needs to be installed, the user inserts the T-shaped plate 24 along the through groove 113 into the trapezoidal ring shaft 111. At this time, the elastic component 115 contracts, and the horizontal plate of the T-shaped plate 24 is located in the movable groove 114. The user rotates the T-shaped plate 24 so that the horizontal plate of the T-shaped plate 24 corresponds to the fixed groove 112. Afterwards, the user releases the force, freeing it from external pressure. The elastic component 115, along with the horizontal plate of the T-shaped plate 24, is inserted into the fixing slot 112 to secure the entire explosion-proof audible and visual alarm. When disassembling the explosion-proof audible and visual alarm body 3, the user needs to lift the entire body and move it upwards. At this time, the spring 1154 contracts. The user then rotates the body to make the horizontal plate of the T-shaped plate 24 leave the fixing slot 112 and align with the through slot 113. After that, the body can be removed by moving it downwards. Since the user needs to lift the body throughout the assembly and disassembly process, the body will not fall during assembly and disassembly, thus improving the practicality of the explosion-proof audible and visual alarm.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
