[0027] Example: A cable lead protection tube that is easy to install, such as Figure 1-Figure 4 As shown, it includes a lower protective plate 3, a limit block 301, an upper protective plate 4 and a protrusion 401. One end of the two lower protective plates 3 is fixedly connected to the limit block 301. The ends of the two lower protective plates 3 away from the limit block 301 are provided with a slot 302 for inserting the limit block 301. The two lower protective plates 3 are connected by the limit block 301 and the slot 302. The top of the lower protective plate 3 is rotatably connected to the upper protective plate 4. The upper protective plate 4 is provided with protrusions 401 on opposite sides. and the card slots 402 that match them, the multiple upper protective plates 4 are limited and fixed by plugging together the protrusions 401 and the card slots 402. There are two upper protective plates 4 distributed on each lower protective plate 3, and the two lower protective plates 3 form a hollow cylindrical structure design when they are enclosed. After the upper protective plates 4 are flipped upward, each upper protective plate 4 is enclosed into a hollow cylindrical structure design, and the inner diameter and outer diameter of the hollow cylinder formed after the upper protective plates 4 are enclosed are the same as the hollow cylinder formed after the lower protective plates 3 are enclosed.

[0028] Among them, the cable lead-in wire is placed on the inner side of the lower protective plate 3, and the limit block 301 of the lower protective plate 3 is plugged into the slot 302 of the other lower protective plate 3 to realize the end-to-end connection of the two lower protective plates 3, so that the two lower protective plates 3 form a first protective sleeve to protect the cable lead-in wire. The cable lead-in wire is located in the first protective sleeve, which saves the process of finding the cable lead-in wire head and then inserting the head from one end of the integrally formed protective sleeve, simplifies the operation, saves installation time and improves installation efficiency; if the cable lead-in wire has other structures located outside the first protective sleeve If protection is needed, the upper protective plate 4 can be flipped over so that its protrusion 401 enters the slot 402 of the adjacent upper protective plate 4 to complete the enclosure and fixation, so that each upper protective plate 4 together forms a second protective sleeve for protecting the cable lead-in line, so that the cable lead-in line is located outside the first protective sleeve and the structure that needs to be protected is located inside the second protective sleeve. Compared with the process of fixing another one-piece sleeve by screw connection or welding on the basis of the original one-piece sleeve, the operation of this embodiment is simpler and the installation efficiency is higher, and it also achieves the purpose of providing reliable protection for the cable lead-in line.

[0029] like Figure 1-Figure 2 As shown, the bottoms of the two lower protective plates 3 are fixedly connected to a base 1, and the two bases 1 are enclosed to improve the stability of the lower protective plates 3. A connecting pipe 2 is fixedly connected to the base 1, and a threaded hole 201 is opened on the connecting pipe 2. The two bases 1 are connected through the threaded hole 201 and the fixing screws. The base 1 is rotatably connected to a limit rod 7, and the number of the limit rods 7 corresponds to the number of the upper protective plates 4. The design of the base 1 can lower the center of gravity of the lower protective plate 3, effectively improve the stability of the device, and ensure that the device can provide efficient protection for the cable lead-in line.

[0030] like Figure 1 As shown, a sealing sleeve 5 is movably provided at one end of the upper protective plate 4 away from the lower protective plate 3. The inner diameter of the sealing sleeve 5 is smaller than the inner diameter of the hollow cylinder formed after the upper protective plate 4 is enclosed. The sealing sleeve 5 can cover the opening above the upper protective plate 4 to prevent insects, rodents and other creatures from entering the device and damaging the cable lead-in line, thereby improving the comprehensiveness of the protection work.

[0031] like Figure 1 As shown, fastening rings 6 are provided on the upper protective plate 4 and the lower protective plate 3. The fastening rings 6 can further improve the tightness of the connection between the components in the device, prevent the components from falling off, and increase the service life of the device.

[0032] This device is used to protect the cable lead-in line. When in use, one end of the cable lead-in line is passed through the sealing sleeve 5. Then the worker takes out the upper protective plate 4 and the lower protective plate 3 connected thereto, and then places the cable lead-in line between the two lower protective plates 3. Then, the limiting block 301 of one of the lower protective plates 3 is inserted into the slot 302 of the other lower protective plate 3, so that the two lower protective plates 3 are connected through the limiting block 301 and the slot 302. Then, the limiting rod 7 is rotated to release the limiting effect of the limiting rod 7 on the upper protective plate 4. Then, the worker flips the upper protective plate 4 upwards so that the upper protective plate 4 moves above the lower protective plate 3 and is connected to the lower protective plate 3. The lower protective plate 3 is on the same straight line. During the flipping of the upper protective plate 4, the protrusion 401 on the upper protective plate 4 gradually moves into the card groove 402 of the adjacent upper protective plate 4 until the protrusion 401 on the upper protective plate 4 enters the card groove 402 of the adjacent upper protective plate 4, thereby realizing the enclosure and fixation of the upper protective plate 4. After completion, the sealing sleeve 5 is put on the end of the upper protective plate 4 to further fix the upper protective plate 4. Thereafter, the base 1 is installed on the ground and the two bases 1 are connected by fixing screws. At this point, the installation of the device is completed, and the protection of the cable lead-in is realized.

[0033] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
