Description

Technical Field

[0001] The utility model relates to the technical field of PVC sleeves, and specifically relates to a PVC sleeve convenient for threading. Background Technique

[0002] Based on the good insulation performance, flexibility, oil and acid resistance of PVC sleeves, they are widely used in the insulation of lead wires of electrical appliances, motors, and transformers, the insulation sleeve protection of wire harnesses and electronic components, gas and liquid flow pipes, etc. to play a protective role. When laying wires in buildings, it is usually necessary to pre-embed PVC sleeves at the positions of the walls or buried underground where the wires need to be laid. After pre-embedding, it can prevent rainwater, sundries or insects from entering the threading pipe and causing a short circuit in the circuit. And after the wires are threaded through the pipe, the pipe orifice should be sealed. In order to improve the efficiency of wire laying, a PVC sleeve is needed. However, the existing PVC sleeves still have the following deficiencies:

[0003] For example, the utility model with the application number 202120891033.5 discloses a PVC composite sleeve. In this utility model, the threaded ring is screwed counterclockwise to the right, and the ring is pushed to the right. When the ring moves to the right, it can drive the thin block to move to the right. The thin block will no longer abut against the bottom of the front and back sides of the arc shell, and the bottom of the square block will no longer be blocked, so the square block can move downward, and the top of the square block will move out of the first square opening. The movable arc shell will no longer be limited. After moving the movable arc shell to its original position to the left, the spliced pipe body can be disassembled, and the later disassembly is relatively convenient to solve the problem that the existing PVC composite sleeve is not easy to disassemble. However, for the comparative documents similar to the above application, when the existing PVC sleeves are used, since most PVC sleeves use tape winding to seal the pipe orifice, this makes the tape easy to stick to the wires, and at the same time affects the subsequent pulling and use of the wires, resulting in the problems of reduced practicability and use efficiency of the PVC sleeves.
