[0002] Wire tube, also known as wire duct, is a piping system used for laying and protecting wires and cables. It is widely used in electrical engineering to organize, protect and guide wires and cables, while providing physical support and isolation to ensure the safe and reliable operation of electrical systems.

[0003] However, most of the protective devices for wire tubes in weak current projects do not protect the wire tube heads during transportation. During transportation, the wire tubes are deformed due to external forces, resulting in excessive damage after transportation to the destination, which not only increases costs but also easily causes quality defects.

[0004] At the same time, most protective devices do not protect the inside of the wire tube. When multiple wire tubes are squeezed against each other during transportation, the wire tubes are easily deformed, and too much dust enters the inside, thus affecting the subsequent use by the staff.

[0023] See also Figure 1-5As shown, a protective device for a weak current engineering wire pipe comprises a protective sleeve 1, which can protect the weak current engineering wire pipe and effectively prevent the wire pipe from being deformed due to external force, thereby increasing the service life of the wire pipe. Connecting shells 2 are fixed on both sides of the protective sleeve 1, a fixing block 3 is fixed on the inner wall of the protective sleeve 1, a tightening belt 4 is fixed on the top of the fixing block 3, and the tightening belt 4 is located inside the protective sleeve 1. The fixing block 3 can make the tightening belt 4 always inside the protective sleeve 1, effectively preventing the tightening belt 4 from shifting during operation, thereby increasing the stability of the device. The number of the fixing block 3 and the tightening belt 4 are both two and they are symmetrically designed with the central axis of the protective sleeve 1, which can effectively increase the effect of the device on fixing the wire pipe. The use effect of the device is increased. A tightening mechanism 5 is installed inside the connecting shell 2. Under the action of the tightening mechanism 5, the tightening belt 4 can bundle several wire tubes, effectively preventing the wire tubes from shaking inside the protective sleeve 1, thereby reducing the deformation of the wire tubes and increasing the use effect of the device. A first threaded rod 7 is provided on one side of the protective sleeve 1. One end of the first threaded rod 7 penetrates into the interior of the protective sleeve 1 and is rotatably connected to the penetration point. One end of the first threaded rod 7 is threadedly connected to a moving disk 8. The surface of the moving disk 8 is hinged with an articulated rod 9. One end of the articulated rod 9 is hinged with a slider 12. The inner cavity of the protective sleeve 1 is slidably connected with a chuck 10. The surface of the chuck 10 is provided with a slide groove 11. The inner cavity of the slider 12 is threadedly connected with a second threaded rod 7. Rod 13, a sponge block 14 is fixed at one end of the second threaded rod 13, and the number of sponge blocks 14 is several. The sponge block 14 can effectively prevent dust from entering the inside of the wire tube, and can support the wire tube, effectively preventing multiple wire tubes from squeezing each other and causing deformation, increasing the stability of the device, thereby increasing the practical effect of the device. With the cooperation of the first threaded rod 7 and the movable plate 8, the hinged rod 9 can drive the slider 12 to simultaneously contract and open inside the slide groove 11, and at the same time, the slider 12 drives the sponge block 14 to move inside the protective cover 1 through the second threaded rod 13, so that the device can block wire tubes at different positions, which not only increases the practical effect of the device, but also effectively prevents dust from entering the inside of the wire tube. The situation, thereby increasing the use effect of the device. With the cooperation of the slider 12 and the second threaded rod 13, the sponge block 14 can be fixed inside the protective sleeve 1 and is regularly distributed, and it is convenient for the staff to replace the sponge block 14, so that the device can be used multiple times, thereby increasing the use effect of the device. The cross-sectional shape of the slider 12 is a cross and is slidably connected to the inner wall of the slide groove 11, which effectively prevents the slider 12 from escaping from the inside of the chuck 10 during operation, thereby increasing the stability of the device. The number of articulated rods 9 and the slide groove 11 are six respectively, and are designed in a ring array with the central axis of the protective sleeve 1. With the increase in quantity, the position of the chuck 10 can be effectively prevented from shifting during operation.This increases the stability of the device and enables the device to block several wire tubes at the same time, thereby increasing the practical effect of the device.

[0024] The tightening mechanism 5 includes a worm 51, one end of which passes through one side of the connecting shell 2 and is rotatably connected to the penetration point. A worm wheel 52 is meshed on the surface of the worm 51, and a tightening gear 53 is fixed to one side of the worm wheel 52. A clamping groove 54 is opened on the surface of the tightening belt 4. The number of the clamping grooves 54 is several. The surface of the tightening gear 53 meshes with the inner wall of the clamping groove 54 and cooperates with each other. Under the cooperation of the worm 51 and the worm wheel 52, the tightening gear 53 can drive the tightening belt 4 to be tightened inside the connecting shell 2 through the clamping groove 54, so that the device can fix several wire tubes, effectively preventing the wire tubes from shaking and reducing the deformation of the wire tubes due to external forces, thereby increasing the practical effect of the device. A bearing seat 6 is fixed on one end of the worm 51, and one side of the bearing seat 6 is fixedly connected to the inner cavity of the connecting shell 2, effectively preventing the worm 51 from positional displacement during operation, increasing the stability of the tightening mechanism 5, and thus increasing the stability of the device.

[0025] Working principle: First, the staff puts several wire tubes into the protective cover 1, so that the wire tubes correspond to the sponge blocks 14 one by one. When the wire tubes need to be fixed, the staff drives the worm wheel 52 to rotate through the worm 51, and the worm wheel 52 drives the tightening gear 53 to rotate, so that the tightening gear 53 rolls up the tightening belt 4 through the card slot 54, so that the tightening belt 4 fixes several wire tubes inside the protective cover 1. When it is necessary to block wire tubes of different widths, the staff replaces the sponge block 14 so that the diameter of the sponge block 14 Corresponding to the inner diameter of the wire tube, the staff then drives the movable plate 8 to move inside the protective sleeve 1 through the first threaded rod 7, so that the movable plate 8 drives the slider 12 to shrink and open simultaneously inside the slide groove 11 through the hinged rod 9, and the slider 12 drives the sponge block 14 to move through the second threaded rod 13, and under the action of the movement of the chuck 10, the sponge blocks 14 can enter the inside of the wire tube one by one, thereby preventing multiple wire tubes from squeezing each other and causing deformation. Then the staff can put the protected wire tube aside.
