[0050] The hanging and fixing method of the existing hanging fire extinguisher is to directly fix the whole fire extinguisher on the ceiling through a fixing bracket. The supporting stability of the fixing bracket for the fire extinguisher is not good, and the fixing firmness of the fixing bracket for the whole fire extinguisher still needs to be improved.

[0051] Based on the above problems, the following embodiments are proposed.

[0052] Embodiment 1:

[0053] As Figure 1 and Figure 2 shown, a concealed installation component is used to fix a hanging device 16 on a suspended ceiling frame. There is a ceiling on the suspended ceiling frame, and a ceiling hole is formed in the ceiling. The concealed installation component includes:

[0054] A first seat body 1, which is used to be arranged at the top of the ceiling hole and the first seat body 1 is used to connect with the suspended ceiling frame; the first seat body 1 includes an upper end face 3 and a lower end face 4 arranged opposite to each other up and down, and the first seat body 1 is formed with a through hole 2 communicating the upper end face 3 and the lower end face 4;

[0055] A second seat body 17, which is arranged on the upper end face 3 and the second seat body 17 is formed with a limiting cavity 18, and the limiting cavity 18 communicates with the through hole 2; the limiting cavity 18 is used to accommodate at least a part of the hanging device 16 and can limit the hanging device 16;

[0056] A panel 11, which is used to be arranged at the ceiling hole and the panel 11 is located at the bottom of the lower end face 4, and the bottom surface of the panel 11 is flush with the bottom surface of the ceiling;

[0057] When the hanging device 16 is in a state of being limited by the limiting cavity 18, a part of the hanging device 16 can pass through the through hole 2 and be located below the first seat body 1.

[0058] The first base body 1 supports the suspension device 16 in the vertical direction. The shape of the limiting cavity 18 is designed to fit the shape of the part of the suspension device 16 located inside it. The setting of the limiting cavity 18 plays a role in limiting the suspension device 16. Thus, the first base body 1 and the second base body 17 together play a stable and firm supporting and limiting role for the suspension device 16. By fixedly connecting the recessed installation component to the ceiling frame, the suspension device 16 can be fixed on the ceiling frame. The panel is arranged at the ceiling hole and the bottom surface of the panel is flush with the bottom surface of the ceiling, achieving the recessed installation effect.

[0059] Preferably, a jack 21 is fixedly connected to the second base body 17, and a plug 22 is correspondingly inserted into the jack 21. The plug 22 is fixed in the jack 21 by using screws, so that the plug 22 fixes the suspension device 16 in the limiting cavity 18.

[0060] Optionally, in one implementation of this embodiment, as Figure 2 shown,

[0061] the second base body 17 includes a limiting plate and a plurality of limiting ribs 15;

[0062] The limiting cavity 18 is formed by enclosing with the limiting plate, and the limiting cavity 18 plays a role in limiting the suspension device 16 in the horizontal direction;

[0063] A plurality of limiting ribs 15 are arranged at intervals along the peripheral side wall of the limiting cavity in the limiting cavity 18, and the plurality of limiting ribs 15 play a role in limiting the suspension device 16 in the vertical direction.

[0064] In this embodiment, the limiting cavity 18 can be formed by enclosing with one limiting plate, or can be formed by enclosing with multiple limiting plates, as long as the shape of the limiting cavity 18 fits the shape of the suspension device 16 located inside it. The cooperative design between the limiting cavity 18 and the limiting ribs 15 enables the second base body 17 to form effective horizontal and vertical limits for the suspension device 16, further increasing the stability and firmness of the suspension device 16 on the second base body 17.

[0065] Preferably, the limiting ribs 15 are connected between the limiting plate and the first base body 1, which can not only play a role in limiting the suspension device 16, but also increase the strength of the first base body 1 and the second base body 17 itself, thereby enhancing the overall strength of the recessed installation component.

[0066] Optionally, in one implementation of this embodiment, as Figure 1 and Figure 3 shown,

[0067] The first body 1 and the second body 17 are integrally formed or detachably connected; preferably, the first body 1 and the second body 17 are integrally formed.

[0068] The concealed installation component further includes:

[0069] A fixing bracket 6, which is detachably connected to the first body 1 and can support the first body 1; the fixing bracket 6 is used to fix the first body 1 on the ceiling frame.

[0070] In this embodiment, the connection method between the first body 1 and the second body 17 is not specifically limited. While the fixing bracket 6 supports the first body 1, it also serves as a component for connecting to the ceiling frame, making it convenient for the concealed installation component as a whole to be connected to the ceiling frame.

[0071] Optionally, in one implementation manner of this embodiment, as Figure 1 and Figure 3 shown,

[0072] A connection groove 7 is formed on the lower end surface 4 outside the through hole 2;

[0073] The fixing bracket 6 includes a first bracket section 601 and a second bracket section 602;

[0074] The first bracket section 601 is used to connect to the ceiling frame, and the second bracket section 602 is located at the connection groove 7 and is connected to the first body 1.

[0075] In the state where the suspended device 16 is fixed by the concealed installation component,

[0076] The first bracket section 601 is connected to the ceiling frame, and the connection method between the two can be screw connection.

[0077] In this embodiment, when using this concealed installation component to fix the suspended device 16, first, the suspended device 16 is arranged in the limiting cavity 18, then the first bracket section 601 is connected and fixed to the ceiling frame, and then the first body 1, the second body 17 and the suspended device 16 thereon are displaced together to the upper side of the fixing bracket 6, so that the position of the connection groove 7 corresponds to the relative second bracket section 602 and the connection groove 7 is fixedly connected to the corresponding second bracket section 602. Thus, the first body 1, the second body 17 and the suspended device 16 thereon are fixed on the fixing bracket 6. At this time, the device body 9 of the suspended device 16 is located at the top of the ceiling frame and is hidden above the panel, realizing concealed installation.

[0078] When using this concealed installation component to fix the suspended device 16, during the process of placing the first base body 1 on the fixing bracket 6 and fixedly connecting it to the fixing bracket 6, the setting of the connecting groove 7 can pre-fix the first base body 1, facilitating the subsequent use of screws to further fixedly connect the fixing bracket 6 and the first base body 1.

[0079] Optionally, in an implementation manner of this embodiment, as Figure 1 , 3 shown,

[0080] A convex frame 8 is formed on the lower end surface 4, and the convex frame 8 surrounds the outside of the through hole 2. The outside of the convex frame 8 and the lower end surface 4 enclose a connecting groove 7;

[0081] There are two first bracket segments 601, and the second bracket segment 602 is connected between the two first bracket segments 601. The second bracket segment 602 is U-shaped;

[0082] When the second bracket segment 602 is located at the connecting groove 7, the convex frame 8 and the second bracket segment 602 are in contact, and the first base body 1 is clamped inside the second bracket segment 602.

[0083] Specifically, the convex frame 8 is a non-closed frame body, and the non-closed end of the convex frame 8 faces the through hole 2.

[0084] While the convex frame 8 and the lower end surface 4 jointly form the connecting groove 7, it also plays a role in strengthening the first base body 1. The non-closed end of the convex frame 8 faces the through hole 2, which can strengthen the part of the first base body 1 around the through hole 2, thereby further increasing the bearing strength of the first base body 1.

[0085] The second bracket segment 602 is U-shaped, and the U-shaped design makes the second bracket segment 602 adapt to the thickness part of the first base body 1, facilitating the first bracket segment 601 to directly contact the ceiling frame and connect with the ceiling frame;

[0086] The structural design of the fixing bracket 6 makes it have a higher degree of fit with the first base body 1 and the connecting groove 7, making the overall fixing of the concealed installation component more firm.

[0087] Optionally, in an implementation manner of this embodiment, as Figure 1 , 3 shown,

[0088] Both the connecting groove 7 and the fixing bracket 6 are provided with N, and N connecting grooves 7 and N fixing brackets 6 are both spaced apart and surround the outside of the through hole 2, and the N connecting grooves 7 and the N fixing brackets 6 are arranged in one-to-one correspondence;

[0089] Wherein, N is a positive integer, and N≥2.

[0090] In this embodiment, N = 2, and two fixing brackets 6 are symmetrically connected to the lower end face 4 with respect to the suspension device 16. Thus, the two fixing brackets 6 and the first seat body 1 form a composite concealed installation component for carrying and fixing the suspension device 16. The symmetric arrangement of the fixing brackets 6 forms a symmetric support and reinforcement for the first seat body 1, enabling the concealed installation component as a whole to have a more comprehensive supporting effect on the suspension device 16. Consequently, the load-bearing strength and load-bearing firmness of the concealed installation component as a whole are further increased. Compared with the existing single-frame load-bearing components, it has higher load-bearing strength and load-bearing firmness.

[0091] Optionally, in one implementation manner of this embodiment, as Figure 4 shown,

[0092] the suspension device 16 includes a device main body 9 and a functional member. The functional member is disposed at the bottom of the device main body 9 and is used to implement the functions of the suspension device 16;

[0093] The limiting cavity 18 is used to accommodate at least a part of the device main body 9 and can limit the device main body 9;

[0094] The panel 11 is formed with a panel hole;

[0095] When the device main body 9 is in a state limited by the limiting cavity 18, the functional member can pass through the through hole 2 and the panel hole and is located below the panel 11.

[0096] Furthermore, the functional member includes a first functional member 13, and the first functional member 13 has at least one function of sensing the ambient temperature and the smoke concentration;

[0097] The panel hole includes a first panel hole 12, and a connection ring 14 is disposed in the first panel hole 12;

[0098] When the suspension device 16 is in a state limited by the limiting cavity 18, the first functional member 13 passes through the connection ring 14 and is located below the panel 11, and the connection ring 14 is threadedly connected to the first functional member 13;

[0099] One end of the outer peripheral side of the connection ring 14 forms a limiting ring 5. When the connection ring 14 is disposed in the first panel hole 12, the limiting ring 5 plays a fixing role on the panel 11.

[0100] The functional member further includes a second functional member 19, and the second functional member 19 has a function of spraying a fire extinguisher; the panel hole further includes a second panel hole 20;

[0101] When the suspension device 16 is in a state limited by the limiting cavity 18, the second functional member 19 passes through the second panel hole 20 and is located below the panel 11.

[0102] In this embodiment, when the connecting ring 14 and the first functional component 13 are in a connected state, the limiting ring 5 is in close contact with the panel 11. The panel 11 is arranged at the ceiling hole, and the bottom surface of the panel 11 is flush with the bottom surface of the ceiling. The structure of the panel 11 is adapted to the structure of the ceiling hole. The setting of the panel 11 has a decorative effect on the overall concealed installation component, further meeting the requirements of concealed installation. The setting of the connecting ring 14 plays a role in strengthening and fixing the panel 11. By passing the connecting ring 14 through the first panel hole 12 and connecting it with the first functional component 13, the limiting ring 5 tightly presses the panel 11 upward, playing a role in strengthening and fixing the panel 11.

[0103] Specifically, the first functional component 13 is provided with a first thread, and the connecting ring 14 is provided with a second thread adapted to the first thread. The second thread is connected to the first thread, facilitating the installation and disassembly of the connecting ring 14.

[0104] The limiting ring 5 is an elastic ring body. The elastic ring body contacts the panel 11, which is a flexible contact, and can prevent the panel 11 from being damaged by the pressing force.

[0105] Optionally, in an implementation manner of this embodiment, as Figure 1 shown,

[0106] The concealed installation component further includes an adjusting plate 10. The adjusting plate 10 is used to be arranged between the fixed bracket 6 and the ceiling suspension frame. Through the adjusting plate 10, the vertical distance between the fixed bracket 6 and the ceiling suspension frame can be adjusted;

[0107] The height adjusting plate 10 is selectively used according to the sizes of the concealed installation component and the ceiling suspension frame. When the second bracket section 602 at the lowest side in the concealed installation component protrudes from the ceiling suspension frame, the height adjusting plate 10 is used to pad between the first bracket section 601 and the ceiling suspension frame, thereby increasing the height of the fixed bracket 6 from the ceiling suspension frame and keeping the second bracket section 602 from protruding from the ceiling suspension frame, realizing the concealed installation of the concealed installation component.

[0108] Embodiment Two

[0109] This embodiment provides a fire extinguishing device, as Figure 3 shown, including:

[0110] A suspension device 16 and the concealed installation component in Embodiment One;

[0111] The suspension device 16 is a suspended fire extinguisher;

[0112] The suspended fire extinguisher includes a device main body 9, a first functional component 13, and a second functional component 19. The device main body 9 is the main body of the fire extinguisher; the structure of the limiting cavity 18 is adapted to the structure of the part of the fire extinguisher main body located in the limiting cavity 18; both the first functional component 13 and the second functional component 19 are arranged at the bottom of the fire extinguisher main body;

[0113] The first functional component 13 is a temperature sensing mechanism for sensing the ambient temperature and triggering the fire extinguishing action of the suspended fire extinguisher according to the ambient temperature; the second functional component 19 is a nozzle assembly for ejecting the fire extinguishing agent in the main body of the fire extinguisher.

[0114] The panel holes include a first panel hole 12 and a second panel hole 20.

[0115] When the main body of the fire extinguisher is in the limited position by the limiting cavity 18, the first functional component 13 passes through the first panel hole 12 and is located below the panel 11, and the second functional component 19 passes through the second panel hole 20 and is located below the panel 11.

[0116] The suspended fire extinguisher with the concealed installation component can be firmly fixed on the ceiling frame in a suspended ceiling manner, with firm fixation and convenient installation.

[0117] In summary, the ingenious concept of the concealed installation component in this application lies in:

[0118] First, the first seat body plays a supporting role in the vertical direction for the suspended device, and the second seat body plays a limiting role for the suspended device. Thus, the first seat body and the second seat body jointly play a stable and firm supporting and limiting role for the suspended device. By fixedly connecting the concealed installation component with the ceiling frame, the suspended device can be fixed on the ceiling frame, the panel is arranged at the ceiling hole and the bottom surface of the panel is flush with the bottom surface of the ceiling, and is hidden above the panel to achieve the concealed installation effect.

[0119] Second, the matching design between the limiting cavity and the limiting rib enables the second seat body to form effective horizontal and vertical limits for the suspended device, further increasing the stability and firmness of the suspended device on the second seat body; the limiting rib can not only play a limiting role for the suspended device, but also increase the strength of the first seat body and the second seat body itself, thereby enhancing the overall strength of the concealed installation component.

[0120] Third, the fixing bracket and the first seat body form a composite component for carrying and fixing the suspended device. Compared with the existing single-frame carrying component, it has a higher carrying strength, and the fixing brackets are symmetrically arranged to form a symmetrical support and reinforcement for the first seat body, so that the overall component has a more comprehensive supporting effect on the suspended device, thereby further increasing the overall carrying strength and carrying firmness of the component.

[0121] Fourth, the setting of the connecting groove can pre-fix the first seat body, thus facilitating the subsequent use of screws to further fixedly connect the fixing bracket and the first seat body.

[0122] Fifth, the structural design of the fixing bracket enables it to have a higher degree of fit with the first seat body and the connecting groove, thereby making the fixation of the overall component more firm.

[0123] Sixth, by passing the connecting ring through the first panel hole and connecting it with the first functional component, the limiting ring tightly presses the panel upward, playing a role in strengthening the fixation of the panel.

[0124] It can be further understood that in the present disclosure, "a plurality of" means two or more, and other quantifiers are similar thereto.
