Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically to a cable outer protective shell that prevents ultraviolet aging. Background Technology

[0002] A cable is a flexible power transmission unit composed of several insulated conductors, their shields, sheaths, and reinforcements, used to safely and efficiently transmit electrical energy or signals. It consists of copper or aluminum conductors wrapped with insulating materials, then combined with metal shielding, filling, and an outer sheath. It can be laid underground, in conduits, overhead, or underwater, and is widely used in power systems, rail transportation, building power distribution, communication networks, and other fields.

[0003] Cables exposed to outdoor ultraviolet radiation for a long time are prone to cracking and pulverization of the sheath material, resulting in decreased insulation performance and reduced mechanical strength, which in turn leads to safety hazards such as leakage and short circuit. However, existing sheaths are mostly one-time coverings or glued fixation, which are difficult to disassemble after installation. Maintenance or replacement requires breaking the shell to disassemble. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable outer protective shell for preventing ultraviolet aging, including a lower protective shell. The top of the lower protective shell is fixedly connected to an internally threaded sleeve, which is fixedly connected to an upper protective shell by screws. The left end of the upper protective shell is fixedly connected to an upper fixing platform, and the left end of the lower protective shell is fixedly connected to a lower fixing platform. An internally threaded sleeve is fixedly installed inside the upper fixing platform. A threaded rod is threadedly connected to the inside of the internally threaded sleeve. A handle is fixedly connected to the top of the threaded rod, and a connecting plate is fixedly connected to the bottom of the handle. An arc-shaped pressing plate is sleeved on the surface of the connecting plate.

[0005] Through the above technical solution, by setting several internal threaded sleeves on the top of the lower protective shell, the upper protective shell is fixed to it with screws to form a detachable covering structure. The upper fixed platform and the lower fixed platform are then pressed together again by internal threaded sleeves, threaded rods, throttles and arc-shaped pressing plates.

[0006] As a further improvement to the above scheme, the number of the internal threaded sleeves is set to several, and the several internal threaded sleeves are evenly distributed symmetrically on the surface of the top of the protective shell below, and the threaded rod passes through the upper fixed platform.

[0007] By employing the above technical solution, the number and symmetrical arrangement of the internal thread sleeves ensure that the upper and lower shells are subjected to uniform stress, thus avoiding localized stress concentration.

[0008] As a further improvement to the above solution, the lower protective shell is fixedly connected to an external threaded sleeve one at the end away from the lower fixed platform, and the upper protective shell is fixedly connected to an external threaded sleeve two at the end away from the upper fixed platform.

[0009] Through the above technical solution, the setting of external thread sleeve one and external thread sleeve two enables the end of the housing to have a standard threaded interface, which can be directly connected to the extension tube to achieve the extension of the protection length.

[0010] As a further improvement to the above scheme, the external thread sleeve one and the external thread sleeve two have the same radius, and the top of the external thread sleeve one is in contact with the bottom of the external thread sleeve two.

[0011] As a further improvement to the above solution, a locking strip is fixedly connected to the top of the upper fixed platform, and a locking hole is opened at the left end of the locking strip. A locking groove is opened at the top of the lower fixed platform, and a locking plate is inserted into the locking hole. A fixing plate is fixedly connected to the surface of the locking plate, a spring is fixedly connected to the left end of the fixing plate, a pull rod is fixedly connected to the left end of the locking plate, and a mounting platform is slidably connected to the surface of the locking plate.

[0012] Through the above technical solution, the setting of external thread sleeve one and external thread sleeve two enables the end of the housing to have a standard threaded interface, which can be directly connected to the extension tube to achieve stepless expansion of the protection length and facilitate quick fixing during installation.

[0013] As a further improvement to the above solution, the number of the card strips is set to two, and the two card holes are symmetrically distributed at the bottom center of the fixing platform. The end of the spring away from the fixing plate is in contact with the inner wall of the mounting platform, and the end of the mounting platform away from the pull rod is fixedly connected to the surface of the lower fixing platform.

[0014] As a further improvement to the above solution, a slider is fixedly connected to the bottom of the fixing plate, and a groove is provided on the bottom of the inner wall of the mounting platform.

[0015] Through the above technical solution, the guide structure of the slider and the groove ensures that the plate moves in a straight line under the action of the spring, preventing jamming.

[0016] As a further improvement to the above solution, the slider is slidably connected inside the groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting up a lower protective shell, an upper protective shell, an inner threaded sleeve one, a screw, an upper fixing platform, a lower fixing platform, an inner threaded sleeve two, a threaded rod, a throttle, and an arc-shaped pressing plate, allows the cable to be placed between the lower and upper protective shells during operation. The screw passes through the inner threaded sleeve one to achieve quick locking of the upper and lower shells. Then, by rotating the throttle, the threaded rod moves up and down in the inner threaded sleeve two, causing the arc-shaped pressing plate to press down on the cable surface. This achieves both UV aging protection and adjustable, detachable radial positioning of the cable, preventing axial slippage of the shell or excessive adhesion to the cable surface, which would make subsequent disassembly inconvenient.

[0018] This utility model includes an external threaded sleeve I, an external threaded sleeve II, a locking strip, a locking hole, a locking groove, a locking plate, a fixing plate, a spring, a pull rod, and a mounting platform. During operation, the external threaded sleeve I and external threaded sleeve II merge into a complete external threaded interface after the upper and lower shells are closed, which can be directly connected to an external extension pipe thread to achieve rapid expansion of the protection length. At the same time, by pulling the locking plate with the pull rod, the locking plate is disengaged from the locking groove, and the locking strip can be inserted into the locking groove. After releasing the pull rod, the spring returns to its original position, and the locking plate is inserted into the locking hole to complete the locking, thus locking the upper and lower fixing platforms of the whole.

[0022] Please combine Figure 1-5This embodiment of a cable outer protective shell for preventing UV aging includes a lower protective shell 1. The top of the lower protective shell 1 is fixedly connected to an internal threaded sleeve 2. The internal threaded sleeve 2 is fixedly connected to an upper protective shell 3 by screws 4. The left end of the upper protective shell 3 is fixedly connected to an upper fixing platform 5. The left end of the lower protective shell 1 is fixedly connected to a lower fixing platform 6. An internal threaded sleeve 7 is fixedly installed inside the upper fixing platform 5. The internal thread of the internal threaded sleeve 7 is connected to a threaded rod 8. The top of the threaded rod 8 is fixedly connected to a handle 9. The bottom of the handle 9 is fixedly connected to a connecting plate 10. An arc-shaped pressing plate 11 is sleeved on the surface of the connecting plate 10.

[0023] In use, the lower protective shell 1 and the upper protective shell 3 are fixed by screw 4, so that the lower protective shell 1 and the upper protective shell 3 are sleeved on the surface of the cable. At this time, the upper fixing platform 5 is locked on the top of the lower fixing platform 6. The threaded rod 8 is rotated by the throttle 9. The threaded rod 8 rotates inside the inner threaded sleeve 7, which synchronously drives the arc-shaped pressing plate 11 to move up and down and squeeze and fix the cable.

[0024] The number of internal threaded sleeves 1-2 is set to several, and the protective shell 1 below the internal threaded sleeves 1 is symmetrically and evenly distributed on the surface. The threaded rod 8 passes through the upper fixed platform 5.

[0025] The lower protective shell 1 is fixedly connected to an external threaded sleeve 12 at the end away from the lower fixed platform 6, and the upper protective shell 3 is fixedly connected to an external threaded sleeve 13 at the end away from the upper fixed platform 5.

[0026] The external threaded sleeve 12 and the external threaded sleeve 2 13 have the same radius, and the top of the external threaded sleeve 12 is in contact with the bottom of the external threaded sleeve 2 13.

[0027] A locking strip 14 is fixedly connected to the top of the upper fixed platform 5. A locking hole 15 is opened at the left end of the locking strip 14. A locking groove 16 is opened at the top of the lower fixed platform 6. A locking plate 17 is inserted into the inside of the locking hole 15. A fixing plate 18 is fixedly connected to the surface of the locking plate 17. A spring 19 is fixedly connected to the left end of the fixing plate 18. A pull rod 20 is fixedly connected to the left end of the locking plate 17. A mounting platform 21 is slidably connected to the surface of the locking plate 17.

[0028] During installation, the locking plate 17 is pulled by the pull rod 20, causing the locking plate 17 to disengage from the inside of the slot 16. At the same time, the fixing plate 18 compresses the spring 19. Then, the locking strip 14 is inserted into the inside of the slot 16. The pulling force applied to the pull rod 20 is released, and the locking plate 17 is inserted into the inside of the locking hole 15. The upper fixing platform 5 and the lower fixing platform 6 are then fixed.

[0029] There are two clips 14. The two clip holes 15 are symmetrically distributed at the bottom center of the upper fixing platform 5. The end of the spring 19 away from the fixing plate 18 is in contact with the inner wall of the mounting platform 21. The end of the mounting platform 21 away from the pull rod 20 is fixedly connected to the surface of the lower fixing platform 6.

[0030] A slider 22 is fixedly connected to the bottom of the fixed plate 18, and a groove 23 is provided on the bottom of the inner wall of the mounting platform 21.

[0031] The slider 22 is slidably connected inside the groove 23.

[0032] The implementation principle of the cable outer protective shell for UV aging protection in this embodiment is as follows: When protecting the cable outer layer, the lower protective shell 1 is first fitted onto the bottom of the cable, and the upper protective shell 3 is fitted onto the surface of the inner threaded sleeve 2. The lower protective shell 1 and the upper protective shell 3 are fixed by screws 4, so that the lower protective shell 1 and the upper protective shell 3 are fitted onto the surface of the cable. At this time, the upper fixing platform 5 is engaged with the top of the lower fixing platform 6. The threaded rod 8 is rotated by the handle 9. The threaded rod 8 rotates inside the inner threaded sleeve 7, which synchronously drives the arc-shaped pressing plate 11 to move up and down and squeeze and fix the cable, so as to prevent the lower protective shell 1 and the upper protective shell 3 from sliding on the surface of the cable or directly sticking to the surface of the cable, which would be inconvenient for subsequent removal and replacement.

[0033] When the lower protective shell 1 is connected to the upper protective shell 3, the external threaded sleeve 12 and the external threaded sleeve 2 are combined through the external threaded sleeve 12 and the external threaded sleeve 2, which facilitates the extension of the whole device through the external internal threaded tube.

[0034] When it is necessary to attach the upper fixed platform 5 to the top of the lower fixed platform 6, first pull the locking plate 17 by the pull rod 20 so that the locking plate 17 is disengaged from the inside of the locking slot 16. At the same time, the fixing plate 18 compresses the spring 19. Then, the locking strip 14 is inserted into the inside of the locking slot 16. Release the tension applied to the pull rod 20, and the locking plate 17 is inserted into the inside of the locking hole 15. The upper fixed platform 5 and the lower fixed platform 6 are then fixed.
