Description

Technical Field

[0001] The utility model relates to the technical field of fire alarm equipment, in particular to a fire alarm equipment. Background Art

[0002] A fire sound and light alarm is a sound and light alarm device installed on site. When a fire occurs and is confirmed on site, the fire sound and light alarm installed on site can be activated by the fire alarm controller of the fire control center, and emits a strong sound and light alarm signal to alert on-site personnel. The sound and light alarm is set in public places. When an accident or special situation occurs, it will sound an alarm and emit a flashing light to alert people. General sound and light alarms are more commonly used in fire protection systems.

[0003] Fire alarms are mounted directly on the wall or suspended from the ceiling using long-rod bolts. The fire alarm and base are integrated into the design. If the internal electrical components of the fire alarm malfunction or become damaged, tools are required to remove the suspension bolts during disassembly due to the high altitude. This makes disassembly and installation quite cumbersome. Therefore, a fire alarm device is needed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A fire alarm device includes a fire sound and light alarm, which is hoisted under a plate group through a clamping assembly. A cover group is buckled on the bottom end of the fire sound and light alarm. The cover group includes a protective cover, which is buckled on the bottom surface of the fire sound and light alarm. A locking bolt is inserted through a through hole on the top side of the protective cover, and the axial end of the locking bolt is inserted into the interior of the fire sound and light alarm through a threaded hole.

[0007] Preferably, a rubber clip is connected around the inner wall of the protective cover, and a rubber constraint strip is connected to the outer side of the bottom end of the fire sound and light alarm at a position opposite to the rubber clip. The rubber constraint strip and the rubber clip are snap-fitted together, and the protective cover is pre-fixed by interlocking the rubber clip and the rubber constraint strip to ensure the convenience of installation of the protective cover.

[0008] Preferably, the vertical cross-section of the rubber clip is L-shaped, and the vertical cross-section of the rubber constraint strip is U-shaped. The L-shaped horizontal plate end of the rubber clip can be embedded in the U-shaped opening of the rubber constraint strip, so that the rubber clip and the rubber constraint strip can be complementary and docked.

[0009] Preferably, the plate group includes a hanging plate, a long rod bolt is inserted through a through hole on the side of the hanging plate, and a wire hole is opened at the center of the hanging plate. The wire hole design of the hanging plate can facilitate the insertion operation of the line.

[0010] Preferably, wire grooves are provided on both sides of the wire hole at the top of the hanging plate, and restraint rings are installed in the wire grooves. Through the wire groove design of the hanging plate, the extended wire harness can be stored, and the restraint ring can restrain the wire harness.

[0011] Preferably, a ring groove is provided at the bottom end of the hanging plate, and a rubber arc strip is embedded in the ring groove. The bottom end of the rubber arc strip is connected and fixed to the top of the fire sound and light alarm. The rubber arc strip can contact the inner wall of the ring groove of the hanging plate, thereby increasing the friction force of the fire sound and light alarm against the bottom end of the hanging plate, thereby preventing the fire sound and light alarm from rotating easily.

[0012] Preferably, the clamping assembly includes a slider, which is embedded in the inside of the hanging plate through a guide groove, a support spring is connected to the outside of the slider, and the end of the support spring is fixed to the inner wall of the hanger plate guide groove, the bottom end of the slider is connected to a clamping block, and the clamping block is embedded in the side of the fire sound and light alarm through an annular clamping groove, and the fire sound and light alarm is rotated, and then the clamping block is moved and clamped in the annular clamping groove of the fire sound and light alarm, thereby ensuring the stability of the suspended installation of the fire sound and light alarm.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. By setting up a card assembly, the fire sound and light alarm can be easily disassembled and assembled. Compared with the traditional structure, this device rotates the fire sound and light alarm so that the rotating groove of the fire sound and light alarm moves on the surface of the card block, so that the opening of the fire sound and light alarm is adapted to the card block. At this time, the card block can be pulled out of the ring groove of the fire sound and light alarm, and the fire sound and light alarm can be pulled down to remove it, and then the wiring can be inspected and maintained, ensuring the portability of the fire sound and light alarm.

[0015] 2. By setting up the cover group, the pre-fixed installation of the protective cover can be achieved. This device is removed by rotating the locking bolt. After completion, the protective cover can be pulled down and the protective cover can be separated from the bottom of the fire sound and light alarm. Then, the components inside the fire sound and light alarm can be inspected and repaired. When the protective cover is installed, the protective cover is buckled on the bottom of the fire sound and light alarm, and the rubber clip and the rubber restraint strip are reversely buckled and docked, which can facilitate the pre-installation operation of the protective cover and avoid the staff from lifting the protective cover from a high altitude, ensuring the convenience of inspection below the fire sound and light alarm.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-4 A fire alarm device includes a fire sound and light alarm 1, which is hoisted under a plate group 4 through a clamping assembly 3. A cover group 2 is buckled on the bottom end of the fire sound and light alarm 1. The cover group 2 includes a protective cover 21, which is buckled on the bottom surface of the fire sound and light alarm 1. A locking bolt 24 is inserted through a through hole on the top side of the protective cover 21, and the shaft end of the locking bolt 24 is inserted into the inside of the fire sound and light alarm 1 through a threaded hole.

[0024] A rubber clip 22 is connected around the inner wall of the protective cover 21 , and a rubber restraint strip 23 is connected to the outer side of the bottom end of the fire sound and light alarm 1 at a position opposite to the rubber clip 22 . The rubber restraint strip 23 is engaged with the rubber clip 22 .

[0025] The rubber clip strip 22 has an L-shaped vertical section, and the rubber restraint strip 23 has a U-shaped vertical section.

[0026] The plate group 4 includes a hanging plate 41 , a long rod bolt 42 is inserted through a through hole on the side of the hanging plate 41 , and a thread hole is opened at the center of the hanging plate 41 .

[0027] Wire grooves are provided on both sides of the wire hole at the top of the hanging plate 41 , and restraint rings 43 are installed in the wire grooves.

[0028] An annular groove is formed at the bottom end of the hanging plate 41 , and a rubber arc strip 44 is embedded in the annular groove. The bottom end of the rubber arc strip 44 is connected and fixed to the top end of the fire sound and light alarm 1 .

[0029] The clamping assembly 3 includes a slider 32, which is embedded in the inside of the hanging plate 41 through a guide groove. A support spring 33 is connected to the outside of the slider 32, and the end of the support spring 33 is fixed to the inner wall of the guide groove of the hanging plate 41. The bottom end of the slider 32 is connected to a clamping block 31, and the clamping block 31 is embedded in the side of the fire sound and light alarm 1 through an annular clamping groove.

[0030] When the protective cover 21 is buckled onto the bottom end of the fire sound and light alarm 1, the rubber clip 22 and the rubber restraint strip 23 can be buckled into each other, and then the protective cover 21 can be pre-fixed to ensure the convenience of installation of the protective cover 21. When the protective cover 21 is installed at the bottom end of the fire sound and light alarm 1, the L-shaped cross plate end of the rubber clip 22 can be embedded in the U-shaped opening of the rubber restraint strip 23, and then the rubber clip 22 and the rubber restraint strip 23 can be complementary and docked, which is convenient for pre-fixing the protective cover 21.

The wire groove design of the hanging plate 41 can store the extended wire harness. The restraint ring 43 can restrain the wire harness to prevent the wire harness from being loose and exposed.

[0031] When the fire sound and light alarm 1 is installed at the bottom end of the hanging plate 41, the rubber arc strip 44 can contact the inner wall of the annular groove of the hanging plate 41, increasing the friction force of the fire sound and light alarm 1 against the bottom end of the hanging plate 41, preventing the fire sound and light alarm 1 from rotating easily, and moving the card block 31 to the opening of the annular card groove of the fire sound and light alarm 1. When the fire sound and light alarm 1 is docked with the hanging plate 41, the elastic force of the support spring 33 pushes the slider 32, so that the slider 32 drives the card block 31 to be inserted into the opening of the annular card groove of the fire sound and light alarm 1. Through the rotation of the fire sound and light alarm 1, the card block 31 is moved and connected to the inside of the annular card groove of the fire sound and light alarm 1, ensuring the stability of the suspended installation of the fire sound and light alarm 1.

[0032] Working principle: According to the attached Figure 2 With attached Figure 3As shown, when installing the fire sound and light alarm 1, the protective cover 21 can be pre-fastened to the bottom end of the fire sound and light alarm 1 so that the rubber clip 22 and the rubber restraint strip 23 are interlocked and docked. At this time, the locking bolt 24 can be inserted through the side of the protective cover 21 and then inserted into the threaded hole of the fire sound and light alarm 1, thereby completing the installation of the fire sound and light alarm 1;

[0033] Secondly, according to the attached Figure 3 As shown, when the fire sound and light alarm 1 is installed under the hanging plate 41, the line end of the fire sound and light alarm 1 is inserted into the through hole at the center of the hanging plate 41, so that the rubber arc strip 44 contacts the annular groove of the hanging plate 41. After completion, the slider 32 can be pushed under the elastic force of the support spring 33, so that the slider 32 drives the card block 31 to move and is inserted into the opening position of the annular card groove on the side of the fire sound and light alarm 1. At this time, the fire sound and light alarm 1 can be rotated to make the card block 31 rotate and engage in the annular card groove of the fire sound and light alarm 1, thereby ensuring the stability of the fire sound and light alarm 1 suspended below the hanging plate 41.
