Description

Technical Field

[0001] The utility model relates to the technical field of electric power pipes, in particular to a spliced ​​electric power pipe. Background Art

[0002] Power conduit, also known as cable protection conduit, is a pipe specifically designed for transmitting power signals. It is widely used in urban power grid construction and renovation, municipal renovation projects, civil aviation airport construction, and the development of industrial parks and residential communities. It primarily protects power cables from external environmental influences, such as compression, tension, and corrosion, while also preventing leakage and external interference.

[0003] During the use of power pipes, it is often necessary to splice multiple sections of power pipes to meet the requirements of cable routing. When connecting multiple sections of power pipes, the existing connection method is mostly to connect and fix them through clamps. In the process of installing the clamps, multiple bolts are also required, resulting in the need to install multiple bolts when connecting the power pipes. This installation method makes the installation of the power pipe not only laborious in operation, but also inefficient. In view of this, we propose a spliced ​​power pipe. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0027] This embodiment provides a technical solution:

[0028] See also Figure 1-Figure 5 As shown, a spliced ​​power pipe includes two symmetrical pipe bodies 1, the outer walls of the pipe bodies 1 are fixed with ear plates 10 at both ends, and one side wall of the ear plate 10 is provided with a limiting groove 100; a fixing ring 2 is provided at the connection between the two pipe bodies 1, and the outer wall of the fixing ring 2 is provided with two symmetrical fixing grooves 20, and the front and rear walls of the fixing ring 2 are fixed with an insert ring 21, which is inserted into the opening of the pipe body 1, and a connecting ring 22 is fixed to the outside of the insert ring 21, and the end of the pipe body 1 is inserted into the gap between the insert ring 21 and the connecting ring 22; a connecting component 3 is provided at the fixing groove 20, and the connecting component 3 includes a shell 30 plugged into the fixing groove 20, and a bottom center of the shell 30 is provided. The connecting cavity 300 has sliding cavities 301 on both the front and rear sides of the connecting cavity 300, and the top of the ear plate 10 is inserted into the corresponding sliding cavity 301; two symmetrical secondary bevel gears 32 are rotatably installed in the connecting cavity 300, and the main bevel gear 31 is engaged with the upper part between the two secondary bevel gears 32, and the secondary bevel gears 32 are coaxially keyed with threaded rods 33, and the threaded rods 33 are inserted into the sliding cavity 301; a slider 34 is slidably installed in the sliding cavity 301, and a threaded hole is provided on one end face of the slider 34 close to the threaded rod 33 to be threadedly connected to the threaded rod 33; two end faces of the two sliders 34 that are away from each other are fixed with two limit blocks 35, and the limit blocks 35 are plugged into the limit grooves 100.

[0029] In this embodiment, the fixing ring 2, insert ring 21, and connecting ring 22 are integrally molded and are all made of plastic. This integral molding provides enhanced connection strength and ensures the stability of the connection between the fixing ring 2, insert ring 21, and connecting ring 22. The plastic material is easy to process and corrosion-resistant, ensuring the service life of the fixing ring 2, insert ring 21, and connecting ring 22.

[0030] In this embodiment, the slider 34 is rectangular in shape, and the size of the slider 34 matches the size of the slide cavity 301. This design facilitates the slider 34 to slide smoothly and steadily in the slide cavity 301, and avoids the slider 34 from shaking.

[0031] In this embodiment, the slider 34 and the stopper 35 are integrally formed, and both are made of stainless steel. The integrally formed slider 34 and stopper 35 have better connection strength, thereby ensuring the stopper 35 has a good limiting effect on the lug 10.

[0032] In this embodiment, a connecting shaft 36 is coaxially keyed to the main bevel gear 31. The top end of the connecting shaft 36 passes through the housing 30. A rotating head 37 is coaxially keyed to the top end of the connecting shaft 36. The cross-sectional shape of the rotating head 37 is a regular hexagon. Rotating the rotating head 37 with a tool such as a wrench rotates the main bevel gear 31, thereby facilitating the disassembly and assembly of the connecting assembly 3.

[0033] In this embodiment, the dimensions of the housing 30 match those of the fixing groove 20, and the housing 30 is made of stainless steel. This matching size helps ensure the stable installation of the housing 30 within the fixing groove 20, while stainless steel offers the advantages of corrosion resistance and high structural strength, ensuring effective fixing of the two tubes 1.

[0034] In this embodiment, the size of the insert ring 21 matches the opening size of the tube body 1, and the size of the end of the tube body 1 matches the gap size between the insert ring 21 and the connecting ring 22. This design facilitates stable cooperation between the tube body 1, the insert ring 21, and the connecting ring 22, ensuring the stability of the docking of the tube body 1.

[0035] It can be understood that after the ear plate 10 in this embodiment is inserted into the sliding cavity 301, it is located at the end of the sliding cavity 301. When the limit block 35 is inserted into the limit groove 100, the ear plate 10 is stably restricted in the sliding cavity 301, thereby ensuring the connection stability between the two tube bodies 1.

[0036] During specific use, the user first places the fixing ring 2 between the two tube bodies 1, and inserts the two ends of the tube body 1 into the gap between the insert ring 21 and the connecting ring 22, then the user aligns the shell 30 with the fixing groove 20 and inserts the ear plate 10 into the sliding cavity 301 on both sides, and then the user uses a wrench to rotate the rotating head 37, and the rotating head 37 drives the connecting shaft 36 and the main bevel gear 31 to rotate. Because the main bevel gear 31 is engaged with the secondary bevel gear 32, the secondary bevel gear 32 drives the threaded rod 33 to rotate. At this time, the sliders 34 on both sides move synchronously relative to each other, and the sliders 34 simultaneously drive the limit blocks 35 to move to both sides. The limit blocks 35 are simultaneously inserted into the limit grooves 100, and the shell 30 is fixed to the ear plates 10 on both sides. Finally, the user repeats the above steps and installs another connecting component 3, and the two tube bodies 1 are connected.

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
