Description

Technical Field

[0001] This utility model relates to the field of municipal lighting facility installation technology, and in particular to a prefabricated distribution box base for municipal lighting that can be installed quickly. Background Technology

[0002] Distribution boxes for municipal lighting systems (such as streetlights and landscape lights) are core equipment for ensuring power distribution and control, and their installation stability directly affects the safe operation of the lighting system. Traditionally, distribution box bases are constructed by pouring concrete on-site, a method that has a long construction period.

[0003] To shorten the construction period, existing technologies currently use prefabricated distribution box bases. However, these bases often employ complex bolted connections for fixing, which results in slow installation, low installation efficiency, and significant inconvenience for subsequent disassembly. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated distribution box base for rapid installation of municipal lighting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A prefabricated distribution box base for rapid installation of municipal lighting includes a groove at the center of the top of the mounting base and a locking structure on the mounting base. The distribution box is placed in the groove, and the interior of the mounting base is a hollow structure. The locking structure includes a self-locking control component, a bidirectional screw rod that is connected to the inner wall of one side of the mounting base through a sealed bearing, two locking blocks that are symmetrically screwed to the two opposite threaded ends of the bidirectional screw rod, and two pins that are symmetrically welded to the outer wall of the adjacent side of the two locking blocks.

[0006] As a further description of the above technical solution, a linear guide rail is fixedly connected to the bottom inner wall of the mounting base, and the lower parts of the two locking blocks are slidably connected to the linear guide rail.

[0007] As a further description of the above technical solution, the self-locking control assembly includes a sealing cover fixedly connected to the side wall of the mounting base, a control shaft that is connected through a sealing bearing to the interior of the rear of the sealing cover, a worm gear fixedly mounted on the control shaft, and a worm wheel fixedly mounted on one end of a bidirectional screw.

[0008] As a further description of the above technical solution, the worm and worm wheel mesh with each other and are both located inside the sealing cover, and an anti-slip rotating cap is fixedly connected to the outer wall of one end of the control shaft.

[0009] As a further description of the above technical solution, through holes are provided on both sides of the inner wall of the groove, and sealing elements are fixedly installed in both through holes, and two pins are movably inserted into the two sealing elements respectively.

[0010] As a further description of the above technical solution, locking holes are provided on the lower parts of both sides of the distribution box, and the opposite ends of the two pins are respectively inserted into the two locking holes.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model features a locking structure on the mounting base. During installation, simply rotating the outer anti-slip cap in the forward direction allows the two pins to come together and insert into the corresponding locking holes for precise locking. This enables quick installation of the distribution box and improves installation efficiency. Furthermore, during disassembly, simply rotating the outer anti-slip cap in the reverse direction allows the two pins to move away from each other and return to their original positions, enabling quick disassembly of the distribution box and facilitating subsequent disassembly, thus improving disassembly efficiency. 2. The self-locking control component of this utility model not only facilitates manual operation of the internal bidirectional screw rotation, but also, through the self-locking performance of the worm gear and worm wheel meshing, can prevent the bidirectional screw from unexpectedly reversing due to external force, thereby ensuring the stability of the two locking blocks after locking, and thus ensuring the firmness of the distribution box installation.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-6 This embodiment discloses a prefabricated distribution box base for rapid installation of municipal lighting, which includes a groove 2 opened at the center of the top of the mounting base 1 and a locking structure provided on the mounting base 1. The distribution box body 3 is placed in the groove 2, and the interior of the mounting base 1 is a hollow structure. Specifically, the locking structure includes a self-locking control component, a bidirectional screw 4 that is connected through a sealed bearing to the inner wall of one side of the mounting base 1, two locking blocks 5 that are symmetrically screwed to the two opposite threaded ends of the bidirectional screw 4, and two pins 6 that are symmetrically welded to the outer wall of the adjacent side of the two locking blocks 5; furthermore, a linear guide rail 7 is fixedly connected to the bottom inner wall of the mounting base 1, and the lower parts of the two locking blocks 5 are slidably connected to the linear guide rail 7. The linear guide rail 7 can guide and limit the two locking blocks 5 to ensure the linear movement of the two locking blocks 5. More specifically, the self-locking control assembly includes a sealing cover 8 fixedly connected to the side wall of the mounting base 1, a control shaft 9 that is connected to the rear interior of the sealing cover 8 through a sealing bearing, a worm gear 10 fixedly mounted on the control shaft 9, and a worm wheel 11 fixedly mounted on one end of the bidirectional screw 4. Furthermore, the worm gear 10 and the worm wheel 11 mesh with each other and are both located inside the sealing cover 8. An anti-slip rotating cap 12 is fixedly connected to the outer wall of one end of the control shaft 9. Through the self-locking performance of the worm gear 10 and the worm wheel 11 after meshing, the bidirectional screw 4 can be prevented from being accidentally reversed by external force, thereby ensuring the stability of the two locking blocks 5 after locking, thus ensuring the firmness of the installation of the distribution box 3. Furthermore, through holes are provided on both inner walls of the groove 2, and sealing elements 13 are fixedly installed in both through holes. Two pins 6 are movably inserted into the two sealing elements 13 respectively. Locking holes 14 are provided on both lower sides of the distribution box 3. The opposite ends of the two pins 6 are inserted into the two locking holes 14 respectively. In this way, the two locking blocks 5 can drive the two pins 6 to move closer to each other and insert into the corresponding two locking holes 14 to achieve a precise locking effect. Moreover, the sealing effect of the two sealing elements 13 can prevent external water from seeping into the mounting base 1 from the groove 2.

[0016] Working principle: During installation, the distribution box 3 is placed in the corresponding groove 2. Then, the external anti-slip rotating cap 12 drives the worm gear 10 on the control shaft 9 to rotate forward. Subsequently, the worm wheel 11, which meshes with the worm gear 10, drives the bidirectional screw 4 to rotate forward. Guided by the linear guide rail 7, the two locking blocks 5, which are threaded to the bidirectional screw 4, drive the two pins 6 to move closer together and insert into the corresponding two locking holes 14 to achieve a precise locking effect. This allows for quick installation of the distribution box 3 and improves installation efficiency. Secondly, during disassembly, the worm gear 10 on the control shaft 9 is driven to rotate in the opposite direction by the external anti-slip rotating cap 12. Subsequently, the worm wheel 11 meshing with the worm gear 10 will drive the bidirectional screw 4 to rotate in the opposite direction. Under the guidance of the linear guide rail 7, the two locking blocks 5 threadedly connected to the bidirectional screw 4 will drive the two pins 6 to move away from each other and return to their original positions. At this time, the two pins 6 are completely separated from the two locking holes 14, and the distribution box 3 can be quickly removed from the groove 2. In this way, the distribution box 3 can be quickly disassembled, which improves the disassembly efficiency.
