[0014] As a further solution of the present invention: the bottom end of the sliding rod is connected with a linkage ring.

[0015] As a further solution of the present invention: both sides of the fixing seat shell are respectively threadedly connected with limiting screws, one end of the limiting screw is inserted into the corresponding first strip sliding opening and cooperates with the screw connecting cylinder.

[0016] As a further solution of the present invention: the weight of the lower half of the movable spherical shell is greater than the weight of the upper half thereof.

[0017] Beneficial effects of the present invention:

[0018] 1. When the fixing base housing of the present invention is ceiling-mounted or wall-mounted, the movable spherical housing for connecting the fire lamp body can be self-adjusted relative to the fixing base housing under the action of gravity, that is, when it is ceiling-mounted, it directly droops so that the fire lamp body faces downward, which meets the requirements of ceiling lighting. When it is wall-mounted, it relies on gravity to deflect to an inclined downward position, which meets the requirements of wall-mounted lighting. No manual adjustment is required, and there is no need to replace different mounting bases for connection. When fixing the fixing base housing with screws, the screws are sequentially passed through the screw docking ring on the movable spherical housing and the screw connecting tube on the fixing base housing, and then connected to the wall, so that the movable spherical housing and the fixing base housing are fixed synchronously. There is no need to separately fix the adjustable movable spherical housing before installing the fire lamp body. In this way, the fire lamp body is fixed.

[0019] 2. When the present invention fixes the housing of the fixing seat by means of screws, in the case of ceiling installation, the screw docking ring on the movable spherical housing can be placed in a horizontal position, with its central axis coinciding with or being parallel to the central axis of the screw connecting tube. In the case of wall installation, the screw docking ring can droop under the action of gravity because one end is rotatably connected to the connecting ring. In this case, the central axis of the screw docking ring and the central axis of the screw connecting tube coincide with or are parallel to each other, and then the screw can be inserted. When the screw is inserted into the screw connecting tube, if it is not aligned, the end of the screw can be pressed against the conical guide sleeve, and the screw connecting tube can be slid and adjusted in position by means of the pressing, and finally aligned, so that the screw can pass through easily and be vertically inserted into the wall, which is convenient for stable docking and avoids the screw from tilting during the installation process and affecting the fixing effect.

[0020] 3. The fire lamp body of the present invention relies on the lamp holder to dock with the movable spherical shell. During docking, the elastic latch on the lamp holder can be squeezed and engaged with the limit block of the movable spherical shell to achieve fixed docking. There is no need to replace the docking parts of the lamp body according to different installations, and the elastic latch can slide relative to the lamp holder to facilitate disassembly of the lamp holder.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] like Figure 8 As shown, this is an existing fire lighting lamp installation structure, where Figure a is a ceiling-mounted installation, which is connected to the ceiling position of the building through a ceiling-mounted mounting base 22, and the fire emergency light 24 is installed at the bottom of the ceiling-mounted mounting base 22. Figure b is a wall-mounted installation, which is connected to the wall of the building through a wall-mounted mounting base 23, and the fire emergency light 24 is installed on one side of the wall-mounted mounting base 23. In order to facilitate the lighting of the fire emergency light 24, one end of the wall-mounted mounting base 23 connected to the fire emergency light 24 is tilted downward. Bolt holes are provided on the ceiling mounting base 22 and the wall-mounted mounting base 23, and their respective bolt holes are in contact with the ceiling or wall during installation, which facilitates the bolts to be vertically connected to the ceiling or wall for fixation. From the above, it can be seen that the existing fire lighting lamp installation structure requires the use of mounting bases of different structures in different installation situations; and when the fire emergency light 24 is docked with the corresponding mounting base, it is also necessary to dock with the connecting parts designed according to the mounting base.

[0033] like Figure 1-Figure 7As shown, the fire lighting installation structure includes a fixed base shell 1, a wire threading hole for passing the wire is opened at the center of the fixed base shell 1, the fixed base shell 1 is used to fit the installation position such as the wall or ceiling, and a screw connecting tube 3 is provided in pairs on the top of the fixed base shell 1. The screw connecting tube 3 is used to pass the screw part, which is convenient for the screw part to be connected to the wall to fix the fixed base shell 1. The top of the fixed base shell 1 is provided with a first strip sliding opening 2 in pairs, and a strip sliding groove 6 is provided on the inner wall of the first strip sliding opening 2. The screw connecting tube 3 is connected to the first strip sliding opening 2 through the strip sliding groove 6. The sliding connection is that the screw connecting cylinder 3 can slide laterally in the first strip sliding opening 2. The end of the screw connecting cylinder 3 close to the inner side of the fixing seat housing 1 is connected to a tapered guide sleeve 4. When the screw is inserted into the screw connecting cylinder 3 from the side where the tapered guide sleeve 4 is located, if the screw and the screw connecting cylinder 3 are not completely aligned, as long as the screw enters the range where the tapered guide sleeve 4 is located, the end of the screw can be squeezed onto the inner inclined wall of the tapered guide sleeve 4, and then the screw connecting cylinder 3 is squeezed to slide along the first strip sliding opening 2, and finally the screw connecting cylinder 3 can be aligned with the screw, which facilitates the insertion of the screw.

[0034] The two sides of the fixed seat housing 1 are respectively threadedly connected with a limit screw 5, one end of the limit screw 5 is inserted into the corresponding first strip sliding opening 2 and cooperates with the screw connecting cylinder 3. The first limit screw 5 is used to limit the sliding position of the screw connecting cylinder 3 in the first strip sliding opening 2;

[0035] The bottom of the fixed base shell 1 is fixedly connected to a fixed spherical shell 7, and the upper and lower ends of the fixed spherical shell 7 are open, that is, the fixed spherical shell 7 is an incomplete spherical body, and a movable spherical shell 8 is provided in the fixed spherical shell 7, and the movable spherical shell 8 is rotatably connected to the fixed spherical shell 7 by a rotating shaft, that is, the movable spherical shell 8 can rotate at a certain angle in the fixed spherical shell 7; the weight of the lower half of the movable spherical shell 8 is greater than the weight of its upper half, so when the fixed base shell 1 is installed in a ceiling-mounted manner, the movable spherical shell 8 is vertically downward under the action of gravity, and when the fixed base shell 1 is installed in a wall-mounted manner, the movable spherical shell 8 is deflected relative to the fixed spherical shell 7 under the action of gravity, and one end thereof is deflected to a tilted downward position, meeting the requirements for wall-mounted installation of fire lamps;

[0036] The top of the movable spherical shell 8 is connected to two sides of the connecting ring 10, and a screw docking ring 9 corresponding to the screw connecting tube 3 is provided in the connecting ring 10, and one end of the screw docking ring 9 is rotatably connected to the connecting ring 10 through a rotating shaft;

[0037] When the fixing seat shell 1 is ceiling-mounted, the side of the fixing seat shell 1 provided with the screw connecting tube 3 is horizontally fitted to the corresponding position of the building ceiling. At this time, the movable spherical shell 8 is vertically downward under the action of gravity, and there is no need to adjust the swing. Since one end of the screw docking ring 9 is rotatably connected to the connecting ring 10 by a rotating shaft, the other end of the screw docking ring 9 is drooped under the action of gravity. When fixing, it is only necessary to rotate the screw docking ring 9 to a horizontal position, and then the screw member passes through the screw docking ring 9 from bottom to top. Then, when the end of the screw member hits the corresponding screw connecting tube 3 position, it can squeeze the tapered guide sleeve 4, so that the screw connecting tube 3 moves laterally due to the squeezing, and finally the screw connecting tube 3 is aligned with the screw docking ring 9, which facilitates the screw member to pass through, thereby realizing that the screw member is vertically drilled into the ceiling, and the fixing seat shell 1 is connected to the ceiling. Then, the movable spherical shell 8 remains fixed relative to the fixing seat shell 1 during this process, thereby facilitating the fixed installation of the fire lamp. The above-mentioned screw member can be drilled into the ceiling with the help of a drilling rig or other tool;

[0038] When the fixing seat shell 1 is wall-mounted, the side of the fixing seat shell 1 provided with the screw connecting tube 3 is first vertically attached to the wall. At this time, the movable spherical shell 8 is deflected relative to the fixed spherical shell 7 under the action of gravity, and one end of the movable spherical shell 8 is deflected to a tilted downward position, meeting the fire lamp wall-mounted installation requirements. At the same time, due to the deflection of the movable spherical shell 8 under the action of gravity, the screw docking ring 9 connected to the movable spherical shell 8 through the connecting ring 10 is also deflected, and because one end of the screw docking ring 9 is rotatably connected to the connecting ring 10 through the rotating shaft, the other end of the screw docking ring 9 droops under the action of gravity, so that the central axis of the screw docking ring 9 is parallel to or coincides with the central axis of the screw connecting tube 3, thereby facilitating the screw member to pass through the screw docking ring 9 and the screw connecting tube 3 in sequence, and finally be vertically inserted into the wall, thereby realizing the connection between the fixing seat shell 1 and the wall, and the deflected movable spherical shell 8 is fixed relative to the fixing seat shell 1 during the process of completing the connection between the fixing seat shell 1 and the wall;

[0039] After the fixing base housing 1 is connected to the ceiling or wall by screws, the limiting screws 5 on both sides of the fixing base housing 1 can be rotated so that the ends of the limiting screws 5 abut against the corresponding screw connection tubes 3. This prevents relative sliding between the fixing base housing 1 and the screw connection tubes 3 and achieves fixation.

[0040] A lamp holder 12 is embedded in the bottom of the movable spherical shell 8, and the bottom of the lamp holder 12 is connected to the lamp body 11, and a threading hole for threading the wire is opened on the lamp holder 12, which is convenient for connecting the lamp body 11 with the corresponding wire to achieve power connection; a clamping mechanism is provided between the lamp holder 12 and the movable spherical shell 8, and the clamping mechanism includes an elastic clamping tooth 14 and a limit clamping block 13, there are two elastic clamping teeth 14, and they are respectively arranged on both sides of the top of the lamp holder 12, there are two limit clamping blocks 13, and they are respectively connected to the inner walls of both sides of the movable spherical shell 8, and the limit clamping block 13 cooperates with the elastic clamping tooth 14, and the elastic clamping tooth 14 It is a hook-shaped body, which is convenient for docking with the limit block 13. When the fixed base housing 1 is connected by the screw, the movable spherical housing 8 is also fixed relative to the fixed base housing 1. At this time, the lamp body 11 on the lamp holder 12 can be connected to the wire passing through the fixed base housing 1, and then the lamp holder 12 is embedded in the movable spherical housing 8. During the embedding process, the elastic teeth 14 on the lamp holder 12 are squeezed through the position of the limit block 13, and the elastic teeth 14 are buckled on the limit block 13 to achieve rapid fixed docking. Moreover, this connection method can be realized regardless of whether it is ceiling-mounted or wall-mounted, without the need to replace the connecting parts;

[0041] A second strip-shaped sliding slot 15 is provided on both sides of the top of the lamp holder 12, and the elastic latch 14 is slidably connected with the second strip-shaped sliding slot 15. A limit spring 16 is connected between the elastic latch 14 and the second strip-shaped sliding slot 15. The second strip-shaped sliding slot 15 facilitates the elastic latch 14 to slide out of the limit block 13, so as to facilitate the disassembly of the lamp holder 12; a sliding operation component is provided between the elastic latch 14 and the lamp holder 12, and the sliding operation component includes a pressure ball 17 and an extrusion hemisphere 18. There are two pressure balls 17, and they are respectively connected to one side of the bottom end of the corresponding elastic latch 14 through a rod body. A sliding cavity 21 is provided on the inner walls of both sides of the lamp holder 12. The top of the sliding cavity 21 is an opening, and a sliding rod 19 is slidably inserted into the sliding cavity 21. The bottom end of the sliding rod 19 passes through the sliding cavity 21 and is exposed from the bottom of the lamp holder 12 The extruded hemisphere 18 is connected to the top of the slide rod 19, and the extruded hemisphere 18 cooperates with the corresponding pressure ball 17. The bottom end of the slide rod 19 is connected with a linkage ring 20, which is connected to the slide rods 19 on both sides at the same time. When the lamp holder 12 that has been clamped needs to be removed, only the linkage ring 20 needs to be pushed up, and the linkage ring 20 drives the slide rods 19 on both sides to slide and rise. In this way, the slide rod 19 squeezes the corresponding pressure ball 17 through the extruded hemisphere 18. The pressure ball 17 and the extruded hemisphere 18 contact through the spherical surface and squeeze each other, so that the pressure ball 17 is subjected to a lateral force. In this way, the pressure ball 17 drives the corresponding elastic tooth 14 to slide along the second strip sliding mouth 15, thereby completing the separation from the limit card block 13, and finally facilitating the lamp holder 12 to be taken out of the movable spherical shell 8.

[0042] When the screw is screwed in the hole 14, the screw thread is pulled out of the hole 14, and the screw thread is pulled out of the hole 14. When the screw is screwed in the hole 14, the screw thread is pulled out of the hole 14, and the screw thread is pulled out of the hole 14. When the screw is screwed in the hole 14, the screw thread is pulled out of the hole 14, and the screw thread is pulled out of the hole 14. When the screw is screwed in the hole 14, the screw thread is pulled out of the hole 14, and the screw thread is pulled out of the hole 14.

[0043] When wall mounting is performed, one side of the fixing seat shell 1 provided with the screw connecting tube 3 is vertically attached to the wall. At this time, the movable spherical shell 8 is deflected relative to the fixed spherical shell 7 under the action of gravity, and one end thereof is deflected to a tilted downward position, meeting the requirements for wall-mounted installation of the fire lamp. At the same time, due to the deflection of the movable spherical shell 8 under the action of gravity, the screw docking ring 9 connected to the movable spherical shell 8 through the connecting ring 10 is also deflected, and since one end of the screw docking ring 9 is rotatably connected to the connecting ring 10 through the rotating shaft, the other end of the screw docking ring 9 droops under the action of gravity, so that the central axis of the screw docking ring 9 is parallel to or coincides with the central axis of the screw connecting tube 3, thereby facilitating the screw member to pass through the screw docking ring 9 and the screw connecting tube 3 in sequence, and finally be vertically inserted into the wall, thereby realizing the connection between the fixing seat shell 1 and the wall, and the deflected movable spherical shell 8 is fixed relative to the fixing seat shell 1 during the process of completing the connection between the fixing seat shell 1 and the wall;

[0044] After the fixing base housing 1 is connected to the ceiling or wall by screws, the limiting screws 5 on both sides of the fixing base housing 1 can be rotated so that the ends of the limiting screws 5 abut against the corresponding screw connection tubes 3. This prevents relative sliding between the fixing base housing 1 and the screw connection tubes 3 and achieves fixation.

[0045] After the fixed base housing 1 is connected to the ceiling or mounted on the wall by screws, the movable spherical housing 8 is also fixed relative to the fixed base housing 1. At this time, the lamp body 11 on the lamp holder 12 can be connected to the wire passing through the fixed base housing 1, and then the lamp holder 12 is embedded in the movable spherical housing 8. During the embedding process, the elastic teeth 14 on the lamp holder 12 are squeezed through the position of the limit block 13, and the elastic teeth 14 are buckled on the limit block 13 to achieve rapid fixed docking. Moreover, this connection method can be realized regardless of whether it is ceiling mounted or wall mounted, without the need to replace the connecting parts.

[0046] When it is necessary to remove the already engaged lamp holder 12, it is only necessary to push the linkage ring 20, and the linkage ring 20 drives the slide bars 19 on both sides to slide and rise, so that the slide bars 19 squeeze the corresponding pressurized balls 17 through the squeezing hemispheres 18. The pressurized balls 17 and the squeezing hemispheres 18 contact with each other through the spherical surfaces and squeeze each other, so that the pressurized balls 17 are subjected to a lateral force component, so that the pressurized balls 17 drive the corresponding elastic teeth 14 to slide along the second strip-shaped sliding opening 15, thereby completing the separation from the limit block 13, and finally facilitating the removal of the lamp holder 12 from the movable spherical shell 8.

[0047] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
