Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable protection technology, and relates to industrial electrical cables, specifically an industrial electrical cable protection device. Background Technology
[0002] Cables are a general term for items such as optical cables and electrical cables. When installing cables, they are usually sheathed. The sheath protects the internal cables and enhances their corrosion resistance and flame retardancy.
[0003] A Chinese patent discloses an industrial electrical cable protection device (CN217769347U), which includes a protective shell, a connecting block, a fixing lug, and an adjustment mechanism, capable of accommodating multiple cables and facilitating the installation of multiple cables.
[0004] However, some shortcomings still exist in practical applications. First, the cable installation method is limited to threading; second, the installation process is restrictive, as cables cannot be installed inside the device once the beginning and end of the cable are laid; third, the threading process is cumbersome and requires auxiliary equipment. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a cable protection device for industrial electrical applications. It employs a handle-linked rotating cover structure, creating an open entrance at the top of the device. This simplifies the cumbersome process of inserting cables one by one through narrow wire holes, a common practice in traditional devices. It is also more suitable for scenarios involving the batch installation of multiple cables. A flexible clamping mechanism is achieved between the U-shaped base plate and the U-shaped top plate, allowing for flexible clamping of cables of different specifications and enabling "contact-type fixing." This effectively prevents damage to the cable sheath caused by friction or slippage.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial electrical cable protection device, comprising a rectangular protection frame, wherein the rectangular protection frame comprises a U-shaped base plate, a U-shaped top plate, and a connecting flexible plate; the two sides of the U-shaped base plate and the U-shaped top plate are respectively connected by the connecting flexible plate;
[0007] The U-shaped top plate includes L-shaped support plates on both sides and a rotating cover in the middle; an adjustment mechanism is provided between the L-shaped support plates on both sides and the two sides of the U-shaped bottom plate; one side of the rotating cover serves as a rotating end and is rotatably connected to the L-shaped support plate on one side; the other side of the rotating cover serves as an opening and closing end and forms a stop fit with the L-shaped support plate on the other side; the opening and closing end of the rotating cover is provided with one or more locking switches.
[0008] As a preferred embodiment, the adjustment mechanism includes telescopic limiting rods located at the four corners and threaded adjusting sleeves located in the middle of both sides, restricting the U-shaped top plate to only move up and down relative to each other; the fixed end of the telescopic limiting rod is located on the U-shaped bottom plate, and the moving end of the telescopic limiting rod is fixedly connected to the L-shaped support plate; a threaded adjusting rod is inserted into the threaded adjusting sleeve, the threaded adjusting sleeve is fixed to the U-shaped bottom plate, and the upper end of the threaded adjusting rod passes through the reserved step hole of the L-shaped support plate.
[0009] As a preferred embodiment, the top surface of the threaded adjusting rod has an internal hexagonal groove. Inserting an internal hexagonal wrench into the groove can rotate the threaded adjusting rod to adjust its height, thereby moving the L-shaped support plate and adjusting the distance between the U-shaped base plate and the U-shaped top plate.
[0010] As a preferred embodiment, the bottom surface of the U-shaped base plate is provided with fixing edges on both sides, and a number of fixing through holes are provided on the fixing edges.
[0011] As a preferred embodiment, a handle is fixedly connected to the upper surface of the rotating cover, and the handle is located between two locking switches.
[0012] As a preferred embodiment, the opening and closing end of the rotating cover is provided with an upper overlapping protrusion, and the L-shaped support plate is provided with a corresponding lower overlapping protrusion, the lower overlapping protrusion and the upper overlapping protrusion forming a stop fit.
[0013] As a preferred embodiment, the locking switch includes a return spring located within a limiting groove at the opening / closing end of the rotating cover. One end of the return spring is fixed within the limiting groove, and the other end is fixedly connected to a limiting pin, providing thrust to the limiting pin. A limiting pin hole is provided on the side end face of the L-shaped support plate on the other side, and the limiting pin passes through the opening / closing end of the rotating cover and is inserted into the limiting pin hole. The combination of the rotating cover and the locking switch allows cables to be placed through the opening into the device, simplifying the cable threading process.
[0014] As a preferred embodiment, a displacement lever is fixedly connected to the limiting pin.
[0015] As a preferred embodiment, the connecting flexible plate is a corrugated rubber plate that can be bent and folded, making the distance between the U-shaped bottom plate and the U-shaped top plate adjustable, thereby adjusting the overall space inside the device.
[0016] As a preferred embodiment, the rotating end of the rotating cover is connected to an L-shaped support plate located on one side via a hinge.
[0017] Working principle and usage process of this utility model:
[0018] When in use, the device needs to be fixed in a suitable position by passing bolts through the fixing through holes. Then, pull the displacement block to move the limit pin out of the limit pin hole, and the locking switch will open, thus releasing the restriction on the rotating cover.
[0019] At this point, gripping the handle will rotate the cover, opening the entire device. Place the cable through the opening into the device, and after installation, close the cover. Use an Allen wrench to rotate the threaded adjusting rod, which moves the U-shaped top plate downwards, reducing the gap between the top and bottom plates. This compresses and secures the cable within the rectangular protective frame, effectively preventing cable slippage and subsequent sheath wear.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] First, the convenient opening design: Utilizing a handle-linked rotating cover structure, the top of the device forms an open entrance, eliminating the cumbersome process of inserting cables one by one through narrow wiring holes, as is common in traditional devices. This is particularly suitable for scenarios involving multiple cables installed in batches (such as distribution cabinet wiring, equipment wiring harness organization, etc.), effectively reducing the time spent on cable pulling.
[0022] Second, the adaptive cable fixing mechanism: a threaded adjustment rod is used for vertical adjustment, and a flexible connecting plate between the U-shaped base plate and the U-shaped top plate provides elastic clamping, allowing for the adaptation of cables of different specifications during use. When the threaded adjustment rod is rotated, the U-shaped base plate is gradually pressed down, ensuring a tight fit between the inner surface of the device and the cable, achieving "contact fixing" and effectively preventing damage to the cable sheath due to friction or slippage.

[0030] 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.
[0031] Example: Reference Figure 1-5 The cable protection device for industrial electrical applications shown includes a rectangular protection frame, which includes a U-shaped base plate 1, a U-shaped top plate 2, and a connecting flexible plate 3. The two sides of the U-shaped base plate 1 and the U-shaped top plate 2 are connected by the connecting flexible plate 3.
[0032] In this embodiment, a rectangular protective frame is formed by a U-shaped base plate 1, a U-shaped top plate 2, and a connecting flexible plate 3. The U-shaped top plate 2 includes L-shaped support plates 21 on both sides and a rotating cover 22 in the middle. Adjustment mechanisms are provided between the L-shaped support plates 21 on both sides and the sides of the U-shaped base plate 1. One side of the rotating cover 22 serves as a rotating end and is rotatably connected to the L-shaped support plate 21 on one side via a hinge. The other side of the rotating cover 22 serves as an opening and closing end and forms a stop fit with the L-shaped support plate 21 on the other side. Two locking switches 4 are provided on the opening and closing end of the rotating cover 22. The rotating cover 22 can be rotated open to form an opening at the top of the device, allowing cables to be placed into the device through the opening, enabling cable installation without the need for threading.
[0033] Meanwhile, the connecting flexible plate 3 between the U-shaped base plate 1 and the U-shaped top plate 2 is made of corrugated rubber sheet, which can be bent and folded together according to the distance between the U-shaped base plate 1 and the U-shaped top plate 2, thereby making the volume inside the rectangular protective frame adjustable. This allows the device to be optimized and adjusted according to the number of cables and the space occupied, so that the cables are stacked together as much as possible, avoiding the cables shaking and rubbing inside the device, and effectively preventing damage to the cable sheath.
[0034] Among them, such as Figure 3As shown, to achieve the purpose of adjusting the distance between the U-shaped base plate 1 and the U-shaped top plate 2, this device adopts the following technical solution: an adjustment mechanism is arranged between the U-shaped base plate 1 and the L-shaped support plate 21. The adjustment mechanism includes telescopic limiting rods 13 located at the four corners and threaded adjusting sleeves 11 located in the middle of both sides, restricting the L-shaped support plate 21 to only move up and down relative to each other. The fixed end of the telescopic limiting rod 13 is located on the U-shaped base plate 1, and the moving end of the telescopic limiting rod 13 is fixedly connected to the L-shaped support plate 21; a threaded adjusting rod 211 is inserted into the threaded adjusting sleeve 11, the threaded adjusting sleeve 11 is fixed on the U-shaped base plate 1, and the upper end of the threaded adjusting rod 211 passes through the reserved step hole of the L-shaped support plate 21.
[0035] Furthermore, such as Figure 4 As shown, the upper end of the threaded adjusting rod 211 has an internal hexagonal groove 2111. An internal hexagonal wrench can be used to rotate the threaded adjusting rod 211. The threaded adjusting rod 211 passes through the threaded adjusting sleeve 11. Rotating the threaded adjusting rod 211 can adjust its own height, thereby moving the L-shaped support plate 21 and adjusting the distance between the U-shaped base plate 1 and the U-shaped top plate 2.
[0036] like Figure 1 As shown, in order to fix the device, the U-shaped base plate 1 has fixing edges 12 on both sides of the bottom surface. Several fixing through holes 121 are opened on the fixing edges 12. The device can be fixed in the required position by using bolts through the fixing through holes 121.
[0037] In addition, such as Figure 1 As shown, in order to realize the opening and closing of the rotating cover 22 on the U-shaped top plate 2, the device adopts the following technical solution: the opening and closing end of the rotating cover 22 is provided with an upper overlapping protrusion 221, and the L-shaped support plate 21 is provided with a lower overlapping protrusion 212. The lower overlapping protrusion 212 and the upper overlapping protrusion 221 form a stop fit.
[0038] A handle 5 is fixedly connected to the upper surface of the rotating cover 22, and the handle 5 is located between two locking switches 4. The locking switch 4 includes a return spring 41, which is located in the limiting groove 222 at the opening and closing end of the rotating cover 22. One end of the return spring 41 is fixed in the limiting groove 222, and the other end is fixedly connected to the limiting pin 42. A limiting pin hole 213 is opened on the side end face of the L-shaped support plate 21 on the other side. The limiting pin 42 passes through the opening and closing end of the rotating cover 22 and is inserted into the limiting pin hole 213. A displacement block 43 is fixedly connected to the limiting pin 42.
[0039] refer to Figure 1-5 The working principle and usage procedure of an industrial electrical cable protection device are as follows:
[0040] When in use, the device needs to be fixed in a suitable position by passing a bolt through the fixing through hole 121. Then, pull the displacement lever 43 to move the limit pin 42 out of the limit pin hole 213, and the locking switch 4 will open, thus releasing the restriction on the rotating cover 22.
[0041] At this point, holding handle 5 will rotate the rotating cover 22, opening an opening in the entire device. After placing the cable through the opening into the device, install and lay the cable, then reset and close the rotating cover 22. Using an Allen wrench to rotate the threaded adjusting rod 211, the threaded adjusting rod 211 moves the U-shaped top plate 2 downward, reducing the gap between the U-shaped top plate 2 and the U-shaped bottom plate 1, thus squeezing and fixing the cable within the rectangular protective frame. This effectively prevents the cable from sliding inside the device and causing wear on the outer sheath.
[0042] 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.
