Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a novel electrical engineering cable protection device. Background Technology

[0002] In the field of electrical engineering, cables serve as crucial carriers for power transmission and signal transmission, and their safety protection directly impacts the stable operation of the entire electrical system. A new type of electrical engineering cable protection device can provide physical protection for cables, preventing damage from external impacts, friction, corrosion, or environmental factors. It is an important piece of equipment for ensuring the quality of electrical engineering construction and the safety of subsequent operation and maintenance. With the increasing scale and complexity of electrical engineering projects, the demand for cable protection devices that offer ease of installation, flexible connection, and adaptability is becoming increasingly prominent.

[0003] Existing electrical engineering cable protection devices mostly employ a split-shell structure, typically consisting of two symmetrical half-shells, which are assembled and fixed using bolts, clips, and other connectors. The technical principle involves placing the cable inside the half-shell, then tightening the bolts to ensure a tight fit between the two halves, or utilizing the elastic deformation of the clips to secure them, forming a closed cavity to protect the cable. Some devices incorporate flanges or grooves on the outer side of the shell, allowing for the splicing of multiple protection devices using additional connectors.

[0004] However, existing technologies have shortcomings, such as the cumbersome assembly and connection of protection devices. When assembling and fixing, each bolt hole must be aligned or the clip position adjusted, which is time-consuming. Connecting multiple devices often requires additional tools or complex splicing structures, resulting in numerous steps and unstable connections, severely impacting installation and connection efficiency and failing to meet the demands of rapid electrical engineering construction. Therefore, a novel electrical engineering cable protection device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of electrical engineering cable protection device, which aims to improve the problem of cumbersome operation of existing protection device combinations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel electrical engineering cable protection device includes a protective shell one and a protective shell two. The protective shell one has a fixing plate one fixedly connected to both the left and right sides of its outer wall, and the protective shell two has a fixing plate two fixedly connected to both the left and right sides of its outer wall. A plurality of connecting components are arranged between the fixing plate one and the fixing plate two. The connecting components are arranged in an array and are used to connect the protective shell one and the protective shell two.

[0008] The connecting assembly includes a fixed column, the upper outer wall of which is fixedly connected to the interior of a fixed plate. A movable column is slidably connected to the center of the fixed column. A reset assembly is provided at the bottom of the movable column, which is used to push the movable column back to its original position. A receiving groove is provided at the bottom of the outer wall of the movable column. Multiple ball bearings are provided at the lower interior of the fixed column. The ball bearings are distributed in a circumferential shape and their outer walls are slidably connected to the interior of the fixed column.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a reset spring, one end of which is fixedly connected inside the fixed column, and the other end of which is fixedly connected to the bottom of the movable column.

[0011] As a further description of the above technical solution:

[0012] The second fixing plate has multiple locking holes inside, the positions of which correspond to the connecting components, and the lower outer wall of the fixing column is slidably connected to the inside of the locking holes.

[0013] As a further description of the above technical solution:

[0014] Both the first and second protective shells have connecting blocks fixedly connected to their side walls, and the connecting blocks are used to connect the two protective devices.

[0015] As a further description of the above technical solution:

[0016] Both the first and second protective shells have connecting grooves on their other side walls, and the shape of the connecting grooves is the same as that of the connecting block.

[0017] As a further description of the above technical solution:

[0018] Multiple limiting grooves are provided on both sides of the inner wall of the connecting groove, and the limiting grooves on both sides are distributed in a symmetrical array.

[0019] As a further description of the above technical solution:

[0020] Multiple symmetrical limiting balls are provided on both sides of the inside of the connecting block. The limiting balls are arranged in an array. Each of the side walls of the multiple limiting balls is fixedly connected to a limiting plate. The outer wall of the limiting plate is slidably connected inside the connecting block.

[0022] A limiting spring is provided between the two limiting plates. The limiting spring is located inside the connecting block, and its two ends are fixedly connected to the side walls of the two limiting plates, respectively.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the cable is placed between two protective shells and aligned with the two side fixing plates. The fixing post is inserted into the locking hole. After it is fully inserted, the movable post is released, and the spring returns to its original position, allowing the ball to extend and engage with the groove, thus completing the fixing to protect the cable. This achieves the effect of quick assembly of the protection device, solves the problem of cumbersome operation in the traditional protection device combination method, and improves the installation efficiency of the protection device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4 This utility model provides an embodiment of a novel electrical engineering cable protection device, comprising a protective shell 1 and a protective shell 2. The protective shell 1 and the protective shell 2 are the main structures protecting the cable, both made of high-strength polyvinyl chloride material through injection molding, possessing good insulation, corrosion resistance, and impact resistance. When closed, they enclose the cable, providing dustproof, waterproof, and mechanical damage protection. The left and right sides of the outer wall of the protective shell 1 are integrally molded with fixing plates 3 using an injection molding process. Similarly, the left and right sides of the outer wall of the protective shell 2 are integrally molded with fixing plates 4. Both fixing plates 3 and 4 are made of PVC and are used to install connecting components. The connection and fixation of the protective shell 1 and the protective shell 2 are achieved through the cooperation of these connecting components. Multiple connecting components arranged in an array between the fixing plates 3 and 4 form the core structure for achieving the connection between the two.

[0035] The connecting assembly is based on a fixed post 5, which is made of 304 stainless steel. Its upper outer wall is fixed to a pre-set mounting hole inside a fixed plate 3 via an interference fit, for insertion into the locking hole 10 of a fixed plate 4, providing support for the connection. A guide hole is machined at the center of the fixed post 5, slidably connecting to a movable post 6. The movable post 6 is made of stainless steel with a chrome-plated surface and can slide axially inside the fixed post 5, controlling the extension and retraction of the balls 8. A reset assembly at the bottom of the movable post 6 pushes it back to its original position when no external force is applied, ensuring connection stability. A receiving groove 7, annular in shape and with a width matching the diameter of the balls 8, is milled into the bottom of the outer wall of the movable post 6 to accommodate the balls 8 when the movable post 6 moves downward, allowing the balls 8 to retract into the fixed post 5. Multiple circumferentially distributed balls 8, made of bearing steel, are located at the lower part of the fixed post 5 and can slide radially inside the fixed post 5, engaging with the groove inside the locking hole 10 to achieve locking. The reset assembly includes a reset spring 9. The return spring 9 is made of spring steel. One end of the return spring 9 is welded to the spring seat preset inside the fixed column 5, and the other end is welded to the bottom of the movable column 6. It is used to provide an upward thrust for the movable column 6, ensuring that the movable column 6 is in the upper position when there is no external force, so that the ball 8 extends out of the fixed column 5. The fixed plate 2 4 has multiple locking holes 10 through drilling. The diameter of the locking holes 10 is adapted to the lower outer wall of the fixed column 5, and the position corresponds to the connecting components one by one. The internal annular groove is machined to accommodate the extended ball 8, so as to realize the fixed connection between the fixed plate 1 3 and the fixed plate 2 4.

[0036] Reference Figure 2 and Figure 5Both protective shell 1 and protective shell 2 have integrally molded connecting blocks 11 on their sidewalls using injection molding. The connecting blocks 11 are made of the same high-strength polyvinyl chloride material as the protective shells, with a rectangular cross-section for splicing between the two protective devices. They extend the coverage area of ​​the protective devices by cooperating with connecting grooves 15. The other sidewalls of both protective shells 1 and 2 have connecting grooves 15 milled into them. The shape and size of the connecting grooves 15 are identical to those of the connecting blocks 11, accommodating the connecting blocks 11 of adjacent protective devices to form a tightly fitting connection structure. Multiple symmetrically arranged limiting grooves 16 are drilled on both sides of the inner wall of the connecting grooves 15. These limiting grooves 16 cooperate with the limiting balls 14 inside the connecting blocks 11 to position and fix the connecting blocks 11 within the connecting grooves 15, preventing loosening of the connection. Multiple arrayed limiting balls 14, made of bearing steel, are arranged on both sides of the connecting block 11. They can slide radially inside the connecting block 11 and are used to lock into the limiting groove 16. Each limiting ball 14 is fixedly connected to a limiting plate 13 by welding. The limiting plate 13 is made of 304 stainless steel and is formed by stamping. Its outer wall forms a sliding fit with the guide groove inside the connecting block 11. It is used to synchronously drive the multiple limiting balls 14 to move and transmit the force of the limiting spring 12. The limiting spring 12, made of spring steel, is arranged between the two limiting plates 13. The limiting spring 12 is located at the center inside the connecting block 11 and its two ends are welded to the side walls of the two limiting plates 13 respectively. It is used to provide an outward pushing force for the limiting balls 14, so that the limiting balls 14 can automatically lock into the limiting groove 16 and realize a stable connection between the connecting block 11 and the connecting groove 15.

[0037] Working principle: When using this new type of electrical engineering cable protection device, the operator first places the cable between protective shell 1 and protective shell 2. Then, the fixing plates 3 on both sides of protective shell 1 are aligned with the fixing plates 4 on both sides of protective shell 2. The multiple fixing posts 5 inside the fixing plate 1 are inserted into the locking holes 10 inside the fixing plate 2. When inserting, the operator manually presses down the movable post 6 inside the fixing post 5. The downward displacement of the movable post 6 compresses the return spring 9 and causes the receiving groove 7 to move as well. The displacement of the receiving groove 7 causes the multiple balls 8 to retract into the fixing post 5. When the bottom of the fixing post 5 is fully inserted, the operator releases the movable post 6. The return spring 9 pushes the movable post 6 upward, and the receiving groove 7 also moves upward. At this time, the balls 8 will extend out of the fixing post 5 and get into the groove inside the locking hole 10, thus completing the fixation of protective shell 1 and protective shell 2, thereby achieving the effect of protecting the cable.

[0038] When multiple protection devices need to be connected, the operator aligns the sidewall of one protection device with the sidewall of another protection device, inserts the connecting block 11 of the sidewall of the first protection shell 1 into the connecting groove 15 of the sidewall of the other protection shell 1, and inserts the connecting block 11 of the sidewall of the second protection shell 2 into the connecting groove 15 of the sidewall of the other protection shell 2. At this time, the limiting balls 14 on both sides of the connecting block 11 are squeezed by the inner wall of the connecting groove 15, which in turn drives the limiting plate 13 to retract into the connecting block 11, and causes the limiting spring 12 to be compressed. When the connecting block 11 is fully inserted into the connecting groove 15, the limiting spring 12 pushes the limiting plate 13 back to its original position and pushes the limiting ball 14 into the limiting grooves 16 on both sides of the inner wall of the connecting groove 15, thus completing the connection between the protection devices and achieving the effect of quickly connecting multiple protection devices.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
