Description

Technical Field

[0001] The utility model relates to the technical field of protective sleeves, in particular to a wire-drawing protective sleeve. Background Art

[0002] The wire-drawing protective sleeve is a protective sleeve for the steel strand wire-drawing of an electric pole, which is divided into a telecommunication and a power diagonal wire-drawing protective sleeve, and can also be called a passage warning tube; the wire-drawing protective sleeve is made of brightly colored plastic or is painted with a distinct color on the outside, playing an obvious warning role. Especially in a traffic or industrial environment, it can remind people to pay attention to safety and avoid accidental collisions or damages.

[0003] Nowadays, there are two ways to fix the wire-drawing protective sleeve on the wire. The first is to fix two semi-cylinders together through a plurality of bolts. However, the use of a plurality of bolts makes the installation and subsequent disassembly processes cumbersome. And when one or more bolts are worn or rusted, etc., it is also very inconvenient to disassemble later, and the disassembly process is time-consuming and laborious. The second is to fix two semi-cylinders through a clamping structure. However, in order to fix the two semi-cylinders tightly on the wire, the clamping structure needs to be clamped very firmly to avoid the subsequent separation of the clamping structure due to external force collisions, etc. But after the clamping structure is clamped very firmly, it is also inconvenient for the staff to disassemble the two semi-cylinders later, and the clamping structure is very likely to be damaged during the disassembly process. At the same time, most of the wire-drawing protective sleeves are made of rigid plastic materials and have no protective structure, and are prone to cracking when frequently impacted later. Content of the Utility Model

[0004] The utility model discloses a wire-drawing protective sleeve, which solves the problems that fixing two semi-cylinders together through a plurality of bolts leads to cumbersome installation and disassembly processes; fixing two semi-cylinders through a clamping structure is likely to cause damage to the clamping structure during the disassembly process; and the wire-drawing protective sleeve is prone to cracking when frequently impacted.

[0005] To solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0006] A wire-drawing protective sleeve includes an upper half tube and a lower half tube. L-shaped connecting blocks are fixed at both cross-section positions of the upper half tube, and L-shaped slots for inserting the connecting blocks are opened at both cross-section positions of the lower half tube. An elastic cloth is fixed at the bottom of the lower half tube, and a fixing ring away from the lower half tube is fixed on the elastic cloth; a U-shaped connecting plate is fixed at the top of the upper half tube, and a hook adapted to the fixing ring is fixed on the top surface inside the connecting plate.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] After the cross-section of the upper half pipe and the cross-section of the lower half pipe are in contact, the guy wire is located between the upper half pipe and the lower half pipe. The connecting block is inserted into the slotted opening through the slotted opening. At this time, the ends of the upper half pipe and the lower half pipe are not aligned. Then, the upper half pipe is moved so that the connecting block extends deep into the slotted opening, and the slotted opening can restrict the connecting block, preventing the upper half pipe from being directly pulled apart from the lower half pipe, thus completing the fixation of the upper half pipe and the lower half pipe. Then, use the elastic cloth to pass through the inner side of the connecting plate to wrap the upper half pipe and the lower half pipe. After that, make the movable end of the elastic cloth bypass the top of the connecting plate and tighten the elastic cloth, so that the end of the hook away from the connecting plate enters the fixing ring, completing the connection between the hook and the fixing ring, fixing the elastic cloth. After the protective cloth wraps the upper half pipe and the lower half pipe, it can also play a role in fixing the upper half pipe and the lower half pipe, further preventing the upper half pipe and the lower half pipe from separating. When it is necessary to disassemble the upper half pipe and the lower half pipe subsequently, only need to separate the fixing ring and the hook, then move the upper half pipe to one side so that the connecting block corresponds to the slotted opening, and then move the upper half pipe in the direction away from the lower half pipe so that the connecting block moves outside the slotted opening. The utility model quickly fixes the upper half pipe and the lower half pipe on the guy wire and covers the guy wire. At the same time, the upper half pipe and the lower half pipe can be fixed together tightly and firmly. The subsequent disassembly is also simple and fast. There is no need for the staff to forcefully separate the upper half pipe and the lower half pipe, which will not cause damage to the upper half pipe or the lower half pipe. And the elastic cloth can effectively protect the upper half pipe and the lower half pipe, avoiding hard objects directly hitting the upper half pipe or the lower half pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will specifically describe the content of the present utility model in conjunction with the accompanying drawings and embodiments.

[0016] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model provides a wire-pulling protection sleeve, which includes an upper half tube 1 and a lower half tube 2. At both cross-section positions of the upper half tube 1, L-shaped connecting blocks 4 are fixed. At both cross-section positions of the lower half tube 2, L-shaped slots 5 for inserting the connecting blocks 4 are provided. A stretchable cloth 6 is fixed at the bottom of the lower half tube 2, and a fixing ring 61 far from the lower half tube 2 is fixed on the stretchable cloth 6. At the top of the upper half tube 1, a U-shaped connecting plate 7 is fixed, and a hook 71 adapted to the fixing ring 61 is fixed on the top surface inside the connecting plate 7.

[0017] As Figure 1 and Figure 4 shown, a U-shaped fixing strip 8 is fixed on the outer wall of the lower half tube 2. A screw rod 11 is fixed at the top of the upper half tube 1. A U-shaped moving strip 9 is placed on the outer wall of the upper half tube 1. The side of the moving strip 9 far from the connecting plate 7 is in contact with the side of the fixing strip 8 close to the connecting plate 7. A through hole for the screw rod 11 to pass through is provided at the top of the moving strip 9. A threaded cylinder 12 is sleeved on the screw rod 11 in a threaded connection, and the bottom of the threaded cylinder 12 is in contact with the top of the moving strip 9. When the cross-sections of the upper half tube 1 and the lower half tube 2 are in contact to form a circular tube to cover the wire, the moving strip 9 can be placed on the upper half tube 1, so that the screw rod 11 passes through the through hole on the moving strip 9. The part of the lower half tube 2 covered by the moving strip 9 and the side of this part far from the connecting plate 7 are in contact with the side of the fixing strip 8 close to the connecting plate 7. Then, the threaded cylinder 12 is threadedly connected to the screw rod 11, and the threaded cylinder 12 presses against the moving strip 9 to complete the fixation of the moving strip 9, preventing the upper half tube 1 from moving to the left (in the orientation shown in Figure 1 ). The cooperation of the moving strip 9 and the fixing strip 8 with the connecting block 4 and the slot 5 can effectively fix the upper half tube 1 and the lower half tube 2 together, avoiding the separation or loosening of the upper half tube 1 and the lower half tube 2.

[0018] As Figure 1 and Figure 4 shown, the threaded cylinder 12 includes a head and a barrel. The head is fixed at the top end of the barrel, and the diameter of the head is larger than that of the barrel. A vertical cylinder 91 covering the barrel is fixed at the top of the moving strip 9, and the top of the vertical cylinder 91 is in contact with the bottom surface of the head. The vertical cylinder 91 can cover the barrel of the threaded cylinder 12 and, in cooperation with the head of the threaded cylinder 12, can effectively seal and protect the screw rod 11 and the barrel of the threaded cylinder 12, preventing rainwater from entering the threaded cylinder 12 and causing rust on the screw rod 11, ensuring that the threaded cylinder 12 can rotate smoothly subsequently.

[0019] As Figure 5As shown, rubber pads 3 are fixed on the inner walls of the upper half tube 1 and the lower half tube 2. The rubber pads 3 can increase the friction between the upper half tube 1 and the lower half tube 2 and the wire, and can effectively protect and isolate the wire. At the same time, the rubber pads 3 can also play an insulating role.

[0020] As Figure 1 shown, a rubber ring 62 is fixed inside the fixing ring 61. The rubber ring 62 can increase the friction between the fixing ring 61 and the hook 71, and prevent the fixing ring 61 and the hook 71 from separating due to non-human factors; and a set of fixing rings 61 and hooks 71 are respectively provided.

[0021] As Figure 1 shown, a fluorescent strip 63 is fixed on the surface of the elastic cloth 6. The fluorescent strip 63 can effectively remind passing pedestrians to pay attention to the wire at night, and prevent pedestrians from hitting the upper half tube 1 and the lower half tube 2.

[0022] During use, make the cross-section of the upper half tube 1 contact the cross-section of the lower half tube 2 to cover the wire, and make the left end of the upper half tube 1 be on the left side of the lower half tube 2 (in the Figure 1 orientation shown), so that the upper half tube 1 and the lower half tube 2 are staggered; at this time, the connecting block 4 is inserted into the slot 5, and the distance from the left inner wall to the right inner wall at the opening of the slot 5 is the same as the distance from the left side to the right side of the connecting block 4 (in the Figure 1(in the orientation shown), then move the upper half tube 1 towards the right so that the ends of the upper half tube 1 and the lower half tube 2 correspond to each other. After the connecting block 4 moves with the upper half tube 1, the end of the connecting block 4 away from the upper half tube 1 is inserted into the interior of the slot 5 to complete the fixation of the upper half tube 1 and the lower half tube 2, making it impossible to pull the upper half tube 1 and the lower half tube 2 apart. Moreover, a number of connecting blocks 4 and slots 5 are provided to facilitate better fixation of the upper half tube 1 and the lower half tube 2 together; then pass the movable end of the elastic cloth 6 through the inner side of the connecting plate 7 (the movable end of the elastic cloth 6 first passes through the back of the lower half tube 2 and the upper half tube 1), wrap the upper half tube 1 and the lower half tube 2, and tighten the elastic cloth 6. The elastic cloth 6 can be wound around the upper half tube 1 and the lower half tube 2 for several more turns to facilitate better wrapping of the upper half tube 1 and the lower half tube 2; then make the elastic cloth 6 bypass the top of the connecting plate 7, and insert the movable end of the elastic cloth 6 into the inner side of the connecting plate 7 to connect the hook 71 and the fixing ring 61, completing the fixation of the movable end of the elastic cloth 6, preventing the elastic cloth 6 from spreading. Moreover, the hook 71 can press against the part of the elastic cloth 6 located inside the connecting plate 7 to further increase the stability of the elastic cloth 6 and prevent the elastic cloth 6 from spreading, completing the fixation of the upper half tube 1 and the lower half tube 2 and preventing the upper half tube 1 and the lower half tube 2 from separating; when it is necessary to separate the upper half tube 1 and the lower half tube 2 subsequently, first separate the fixing ring 61 and the hook 71, restore the elastic cloth 6 so that the elastic cloth 6 no longer wraps the upper half tube 1 and the lower half tube 2, then push the upper half tube 1 to the left. After the connecting block 4 corresponds to the opening of the slot 5, the upper half tube 1 and the lower half tube 2 can be separated.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
