Description

Technical Field

[0001] The utility model belongs to the technical field of lamp poles, and in particular relates to a waterproof protective wire coil and a multifunctional lamp pole. Background Art

[0002] Smart street lights are a new type of public infrastructure for smart city construction. They are also called smart poles, smart light poles, multifunctional street light poles, etc. They are a general term for poles, towers and other facilities that carry a variety of equipment and sensors and have intelligent capabilities. Smart street lights combine information and communication technology with traditional urban public infrastructure to achieve precise management of various fields in the city and intensive use of urban resources. On the other hand, in order to actively promote the multi-pole integration project, road poles are integrated to effectively save urban space and land resources and reduce construction costs. If the smart light pole uses a main pole threading hole without any waterproof wire protection structure, it is subject to the deformation of the flange connecting the pole and the lamp head or the cantilever arm, or the uneven surface of the connection, such as zinc slag, etc., which can easily cause rainwater to flow along the cable into the inner cavity of the main pole, causing moisture inside the pole and affecting its performance.

[0004] Although the above application enables the protective coil to be installed on the wire threading holes of multifunctional lamp poles of different thicknesses and shapes, greatly improving the scope of application, the wire needs to be threaded through the waterproof inclined hole, which makes it difficult to replace the protective coil after it is aged and damaged. Even if it needs to be replaced, the cable must be taken out of the waterproof inclined hole before the protective coil can be removed from the wire threading hole as a whole, which makes replacement very inconvenient. Therefore, a waterproof protective coil and a multifunctional lamp pole are needed. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with embodiments.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Example

[0023] Although the above application enables the protective coil to be installed on the threading holes 21 of multi-functional lamp poles with different thicknesses and shapes, greatly improving the scope of application, it requires threading through the waterproof inclined holes 12, resulting in difficulty in disassembling and replacing the protective coil after it ages and is damaged. Even when replacement is needed, the cable has to be taken out from the waterproof inclined holes 12 before the entire protective coil can be removed from the threading hole 21, making the replacement extremely inconvenient.

[0024] Therefore, please refer to Figures 1-3 , the present utility model provides a waterproof protective coil, including: a protective coil body, the protective coil body includes two symmetrically arranged waterproof structures, and the protective coil body is formed by the docking of the two waterproof structures;

[0025] The setting of the two waterproof structures can achieve the purpose of facilitating disassembly and replacement without disassembling the cable after the protective coil body has aged after long-term use.

[0026] Furthermore, as shown in Figures 1-3 , specifically, each waterproof structure includes a top cover 1, a hole plug 11 is fixedly connected to one end face of the top cover 1, a waterproof inclined hole 12 for facilitating the cable to pass through is opened on the docking surface of each hole plug 11, and a plurality of equally spaced annular buckles 13 are fixedly connected to the outside of the hole plug 11, and the axial section shape of the annular buckle 13 is wedge-shaped.

[0027] Among them, the structure formed by the docking of the two waterproof structures in this application is the coil main body structure mentioned in a waterproof protective coil and multi-functional lamp pole with the authorization announcement number of CN 220793079U3, and the protective coil body is made of an insulating elastic material.

[0028] The multi-functional lamp pole of the present utility model includes a lamp pole 2, a plurality of threading holes 21 are provided on the lamp pole 2, the waterproof protective coil as shown in is arranged in the threading holes 21, and sealing and pressing structures 3 are provided around the outer wall of the lamp pole 2, and the sealing and pressing structures 3 are connected to the protective coil body.

[0029] Furthermore, as shown in Figures 1-3As shown, it is worth specifically explaining that the sealing and pressing structure 3 includes an upper insertion channel 31 and a lower insertion channel 32 respectively opened on the front end faces of the two top covers 1. A sealing insert a 33 with a convex cross-section is movably inserted into the two aligned upper insertion channels 31, and a sealing insert b 34 with a convex cross-section is movably inserted into the two aligned lower insertion channels 32. On the side walls of the sealing insert a 33 and the sealing insert b 34 facing the lamp post 2, there are fixedly connected sliders 35 with a convex cross-section. Both sliders 35 are slidably connected to the sliding grooves provided on the outer wall of the lamp post 2. A same hand-tightening screw 36 is threadedly penetrated through the sealing insert a 33 and the slider 35, and a same hand-tightening screw 36 is also threadedly penetrated through the sealing insert b 34 and the slider 35. One end of the two tightened hand-tightening screws 36 abuts against the inner wall of the corresponding sliding groove.

[0030] Among them, the cross-section of the two aligned upper insertion channels 31 is of a convex structure, and the same is true for the two aligned lower insertion channels 32. The length of the sealing insert a 33 is greater than the length of the sealing insert b 34, and the opposite ends of the sealing insert a 33 and the sealing insert b 34 are of a concave arc structure.

[0031] In summary: The waterproof protection coil can be assembled in a butted manner, so that when disassembling and replacing in the follow-up, it is not necessary to take out the cable from the waterproof inclined hole 12 to carry out the overall disassembly, greatly improving the convenience of disassembly and replacement. Secondly, under the action of the sealing and pressing structure 3, on the one hand, it can seal the butting gap of the two top covers 1, effectively preventing moisture from entering the threading hole 21 from the gap and reaching the inside of the lamp post 2. On the other hand, it can press and fix the two top covers 1 on the outer wall of the lamp post 2, avoiding the phenomenon that the two plugging plugs 11 come out of the threading hole 21 when the cable is pulled in the threading hole 21, effectively ensuring the stability after installation. When disassembling the protection coil body from the threading hole 21, the two hand-tightening screws 36 can be loosened, and the sealing insert a 33 and the sealing insert b 34 can be moved away from each other respectively, so that they are respectively disengaged from the two upper insertion channels 31 and the two lower insertion channels 32, and then the protection coil body can be easily disassembled and replaced without removing the cable in the threading hole 21, greatly improving the use convenience.
