[0002] The octagonal lamp socket box with a different edge in the precast composite slab is an innovative accessory for electrical installation, mainly designed for embedded installation in precast concrete composite slabs to facilitate subsequent electrical connections. The octagonal lamp socket box is named after its unique octagonal design, which can provide a larger space, making wire connections more convenient and providing better protection for the lamps.

[0003] In the current field of octagonal lamp socket boxes, most of them connect and fix the cover plate and the box body through bolts and nuts. This design method requires the use of specific tools for disassembly and assembly when placing and retrieving the lamp socket, which not only increases the complexity of construction, but also may reduce the construction efficiency due to the inconvenience of carrying and using tools, thus affecting the project progress. Summary of the Invention

[0004] To make up for the above deficiencies, the present invention provides an octagonal lamp socket box with a different edge that can be fixed in a precast composite slab, aiming to improve the problem that the disassembly and assembly between the cover plate and the box body are inconvenient, thus affecting the project progress.

[0005] To achieve the above object, the present invention provides the following technical solution: An octagonal lamp socket box with a different edge that can be fixed in a precast composite slab, including a box body, a cover plate is arranged at the bottom of the box body, a fixing plate is fixedly connected to the upper surface of the cover plate, two symmetrically arranged fixing blocks are fixedly connected to the upper surface of the cover plate, a clamping block is rotatably connected between the two symmetrically arranged fixing blocks, a telescopic rod is fixedly connected to the outer wall of the clamping block, one end of the telescopic rod is fixedly connected to the outer wall of the fixing plate, a first spring is sleeved on the outer wall of the telescopic rod, one end of the first spring is fixedly connected to the outer wall of the clamping block, and the other end of the first spring is fixedly connected to the outer wall of the fixing plate. The outer wall of the fixing plate is slidably connected to the inside of the box body, and a positioning component is arranged on the upper surface of the cover plate.

[0006] Further, the positioning component includes a limiting block, and the lower surface of the limiting block is fixedly connected to the upper surface of the cover plate.

[0007] Further, the outer wall of the limiting block is slidably connected to the outer wall of the box body, and the outer wall of the fixing plate is slidably connected to the inside of the box body.

[0013] Beneficial effects

[0014] The present invention has the following beneficial effects:

[0015] 1. In the present invention, first, by inserting the limit block into the preset groove of the box body, the positioning effect is achieved, enabling the clamping block to rotate between the two fixed blocks, and at the same time, the spring contracts. When the cover plate is attached to the box body, the spring rebounds and the clamping block is snapped into the inside of the box body to achieve the closing effect.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Refer to Figures 1-3 , an embodiment provided by the present invention: an octagonal lamp holder box with a different edge that can be fixed in a precast laminated slab, including a box body 1, a cover plate 5 is arranged at the bottom of the box body 1, a fixed plate 7 is fixedly connected to the upper surface of the cover plate 5, two symmetrically arranged fixed blocks 8 are fixedly connected to the upper surface of the cover plate 5, a clamping block 9 is rotatably connected between the two symmetrically arranged fixed blocks 8, a telescopic rod 10 is fixedly connected to the outer wall of the clamping block 9, one end of the telescopic rod 10 is fixedly connected to the outer wall of the fixed plate 7, a first spring 11 is sleeved on the outer wall of the telescopic rod 10, one end of the first spring 11 is fixedly connected to the outer wall of the clamping block 9, and the other end of the first spring 11 is fixedly connected to the outer wall of the fixed plate 7. The outer wall of the fixed plate 7 is slidably connected to the inside of the box body 1, and a positioning component is arranged on the upper surface of the cover plate 5;

[0025] Specifically, the clamping block 9 is squeezed by the box body 1, so that the clamping block 9 rotates between the two fixed blocks 8. In this process, the first spring 11 plays a key role. It contracts between the fixed plate 7 and the clamping block 9. To ensure the smooth progress of the contraction process, the telescopic rod 10 guides the contraction of the first spring 11. When the upper surface of the cover plate 5 is completely attached to the lower surface of the box body 1, the first spring 11 is no longer subjected to external force, so it starts to rebound. This process drives the clamping block 9 to move forward, making it snap into the inside of the box body 1. In this way, the box body 1 is tightly closed, ensuring the safety of the contents. The reason why this design is so efficient is the cooperation between the various components. The clamping block 9, the fixed block 8, the first spring 11, the fixed plate 7, the telescopic rod 10 and the cover plate 5 jointly complete a complete closing process. This design not only realizes the tight closing of the box body 1, but can also be applied to various similar occasions, such as packaging, containers, etc.

[0026] Refer to Figure 2 , the positioning component includes a limit block 6, and the lower surface of the limit block 6 is fixedly connected to the upper surface of the cover plate 5;

[0027] Specifically, the box body 1 is preset with a groove to achieve precise docking with the limit block 6, achieving a positioning effect.

[0028] Referring to Figure 4 , the outer wall of the limit block 6 is slidably connected to the outer wall of the box body 1, the outer wall of the fixing plate 7 is slidably connected to the inside of the box body 1, the inside of the box body 1 is threadedly connected with a threaded rod 12, one end of the threaded rod 12 is fixedly connected with a handle 13, the other end of the threaded rod 12 is rotatably connected with a rotating shaft 14, the outer wall of the rotating shaft 14 is fixedly connected with a pushing block 15, the outer wall of the pushing block 15 is slidably connected to the inside of the box body 1, and the upper side inside the box body 1 is fixedly connected with a plurality of wire conduits 2;

[0029] Specifically, during disassembly, the user only needs to operate using the handle 13. The handle 13 is designed just right, with a comfortable grip, making it convenient for the user to hold. By rotating the handle 13, the user can easily drive the threaded rod 12 to rotate inside the box body 1. This design greatly improves the convenience of the disassembly process. The other end of the threaded rod 12 is connected to the rotating shaft 14. When the handle 13 rotates, the threaded rod 12 rotates inside the box body 1, and at the same time, the rotating shaft 14 will also rotate accordingly. This design enables the user to more easily push the pushing block 15 to rotate inside the box body 1 when operating the handle 13. The pushing block 15 is also very cleverly designed. Its surface is specially treated and has good friction, which can ensure stability and not easy to slide during the pushing process. When the pushing block 15 rotates, it will exert pressure on the clamping block 9. This design makes it extremely easy to disassemble the cover plate 5. The cover plate 5 and the box body 1 adopt a snap - type design. Once subjected to the pressure of the pushing block 15, the cover plate 5 can be easily removed from the box body 1. In this way, the user can successfully complete the disassembly and assembly work of the product, greatly improving the work efficiency.

[0030] Referring to Figure 1 , a wire inlet groove 3 is opened at the top of the box body 1, and a different edge 4 is fixedly connected to the lower side of the outer wall of the box body 1. The different edge 4 is made of PVC material;

[0031] Specifically, the height of the different edge 4 should be located at the middle position of the thickness of the precast composite slab. If the thickness of the composite slab is 70 mm, then the center of gravity height of the different edge 4 is 35 mm, and the width of the different edge 4 is 10 mm. When embedding the octagonal lamp socket box in the original way and pouring concrete, attention should be paid to the displacement of the box body 1 and the dense pouring of the concrete under the different edge 4, which can make the state of the lamp socket box fixed on the precast slab more firm, avoiding the loosening phenomenon caused by transportation and extrusion, and the operation is simple without adding more complex construction processes.

[0032] Working principle: When it is necessary to use an octagonal lamp socket box with a special edge that can be fixed in a precast composite slab, a lamp socket is placed inside the box body 1. After placement, the limiting block 6 is aligned with the preset groove of the box body 1 and inserted to achieve the positioning effect. At this time, the clamping block 9 rotates between the two fixing blocks 8 under the extrusion of the box body 1, and at the same time, the first spring 11 contracts between the fixing plate 7 and the clamping block 9. The telescopic rod 10 guides the contraction of the first spring 11. When the upper surface of the cover plate 5 fits with the lower surface of the box body 1, the first spring 11 no longer receives force and rebounds, thereby driving the clamping block 9 to snap into the inside of the box body 1, and then closing the box body 1. During disassembly, only need to rotate the handle 13, thereby driving the threaded rod 12 to rotate inside the box body 1 through the handle 13. Then, one end of the threaded rod 12 rotates inside the rotating shaft 14, pushing the push block 15 to rotate inside the box body 1, thereby pressing the clamping block 9 through the push block 15, so that the cover plate 5 can be removed, achieving the effect of disassembly and assembly.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
