Description

Technical Field

[0001] The utility model relates to the technical field of cables, and particularly relates to a port protection structure for cable pipeline laying. Background Art

[0002] A cable is a device for transmitting electrical energy or signals. It usually consists of several or several groups of wires and has the characteristics of internal power conduction and external insulation. Cables can be used to transmit electrical (magnetic) energy and information to achieve the conversion of electromagnetic energy;

[0003] When installing and laying cables, it is necessary to protect both ends of the cable to prevent foreign objects such as soil from coming into contact with the inside of both ends of the cable, which may affect subsequent cable connections. Currently, the protection method for both ends of the cable usually uses cloth strips to wrap or plastic sleeves of appropriate sizes. This method results in insufficient protection and also allows some impurities to come into contact with the inside of the cable, ultimately affecting subsequent cable connections.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Embodiment:

[0022] Refer toFigures 1-4 , a port protection structure for cable pipeline laying, including a sleeve 1. Handles 2 are installed at both ends of the outer wall of the sleeve 1, and a fixing structure 3 is provided at the center of one end of the sleeve 1. The handles 2 on the outer wall of the sleeve 1 are convenient for hand-held operation and can also be used as a base to support one end of the cable, making it easy to use;

[0023] The fixing structure 3 includes a sealing cavity 4 opened on the inner wall of one end of the sleeve 1, a spring groove 5 opened at the center of the top of the sleeve 1 where the sealing cavity 4 is located, a return spring 8 installed at one end of the inner wall of the spring groove 5, a sliding hole opened at the center of one end of the sleeve 1, a pull rod 6 slidably connected in the sliding hole, and a piston disc 7 installed on the outer wall of the other end of the pull rod 6. The pull rod 6 pulls the piston disc 7 to compress the return spring 8, and the piston disc 7 pushes the gas in the sealing cavity 4 into the airbag 11. After the return spring 8 returns the piston disc 7, the gas is drawn back, which is convenient for recycling.

[0024] The other end of the return spring 8 is installed on the outer wall of the piston disc 7, and the piston disc 7 is hermetically and slidably connected to the inner wall of the sealing cavity 4. Both the piston disc 7 and the pull rod 6 are hermetically and slidably connected in the sleeve 1, ensuring the reuse of the gas inside the sealing cavity 4 and facilitating the fixing of the sleeve 1.

[0025] An expansion slot 10 is opened on the inner wall of the other end of the sleeve 1, and an airbag 11 is placed in the expansion slot 10;

[0026] The sleeve 1 is provided with equally spaced air holes 9 at the position of the spring groove 5, and the other end of the air hole 9 is located at the expansion slot 10. The airbag 11 is communicated with the air hole 9. By pulling the locking rods 16 in opposite directions through the ring 14, the support rings 12 on the locking rods 16 compress the locking springs 13 so that one end of the locking rod 16 leaves the locking hole 15. At this time, the return spring 8 supports the piston disc 7 to return to its position.

[0027] Round holes are symmetrically opened at one end of the sleeve 1, and locking rods 16 are slidably connected in the round holes. A support ring 12 is welded to one end of the outer wall of the locking rod 16, and a locking spring 13 is welded to the outer wall of one side of the support ring 12.

[0028] The other end of the locking spring 13 contacts the inner side outer wall of the sleeve 1, and a ring 14 is welded to the other end of the locking rod 16. A locking hole 15 is opened at one end of the outer wall of the pull rod 6, and one end of the locking rod 16 is inserted into the locking hole 15. After the airbag 11 inside the sleeve 1 is inflated, it extends out of the expansion slot 10 to wrap one end of the cable. The sleeve 1 is thus fixed to one end of the cable, which is convenient for protecting one end of the cable, improving the protection ability, and preventing foreign objects from contacting both ends of the cable.

[0029] Working principle: When in use, the sleeve 1 is sleeved on one end of the cable. At this time, the piston disk 7 is pulled outwards by the pull rod 6. The piston disk 7 moves to compress the return spring 8 and conveys the gas inside the sealing cavity 4 to the inside of the airbag 11 through the air hole 9. After the airbag 11 is filled with gas, it expands and extends out from the telescopic groove 10. The airbag 11 wraps the cable at one end of the sleeve 1, and thus one end of the cable is wrapped inside the sleeve 1. At this time, the pull rod 6 is limited by the locking rod 16 inserted into the locking hole 15. When not in use, the locking rod 16 is pulled in the opposite direction through the ring 14. The support ring 12 on the locking rod 16 compresses the locking spring 13 so that one end of the locking rod 16 leaves the locking hole 15. At this time, the return spring 8 supports the piston disk 7 to return to its original position, and the gas in the airbag 11 is pumped back into the sealing cavity 4 through the air hole 9. After the airbag 11 shrinks, the sleeve 1 can be removed from one end of the cable.
