Description

Technical Field

[0001] The invention relates to the field of electric power technology, and in particular to a cable threading pipe sealing device. Background Art

[0002] During on-site electrical construction, cable laying through the wall is constructed by pre-buried threading pipes and other methods to protect the cables. During the pre-buried electrical threading pipe, a water stop plate is welded in the middle and buried in the wall. After the cable is laid, it is sealed with fireproof mud or cement. This method has the disadvantage of unsatisfactory waterproof effect: first, fireproof mud sealing can only prevent small animals from entering, and has no waterproof effect at all; second, although cement sealing can achieve waterproof effect, it is easy to leak if the cement grouting is not tight, and the cable is sealed and fixed by cement grouting, which is not conducive to cable maintenance; finally, there are many human factors in the welding of the water stop plate, which is prone to water seepage caused by loose welding.

[0003] Aiming at the above-mentioned problem that the cable threading pipe is not tightly sealed and leaks, a cable threading pipe sealing device is needed. Summary of the invention

[0004] Aiming at the problem that the existing cable threading pipe is not tightly sealed and leaks, the present invention proposes a cable threading pipe sealing device.

[0005] The present invention proposes a cable threading tube sealing device, comprising a clamping block clamped on the threading tube, a screw rod inserted on the clamping block, one end of the screw rod is located inside the threading tube and is inserted with a sealing block, a fastening nut is provided at one end of the clamping block away from the sealing block, the fastening nut is threadedly connected to the screw rod, when in use, the fastening nut is rotated to drive the screw rod to move outward, the sealing block is pulled to move by the screw rod, and the sealing block is squeezed, so that the sealing block is axially compressed and vertically expanded, the gap between the cable and the threading tube is blocked, the threading tube is sealed, the threading tube can be effectively prevented from leaking, and the overall use effect is good.

[0006] Furthermore, the card block is in an F shape.

[0007] Furthermore, one end of the screw rod located inside the threading tube is in a T shape.

[0008] Furthermore, one end of the screw rod in a T shape abuts against the blocking block.

[0009] Furthermore, a butterfly cap is fixed on one end of the screw rod away from the threading tube.

[0010] Furthermore, the blocking block is in an arc shape.

[0011] Furthermore, at least two blocking blocks are provided.

[0012] Furthermore, the plurality of blocking blocks are arranged symmetrically or evenly spaced in a ring shape.

[0013] The beneficial effects of the present invention are: The device blocks the threading pipe by a blocking block, which can effectively increase the sealing performance of the threading pipe opening and avoid water ingress into the pipe. The overall use effect is good and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0018] like Figure 1 As shown, in this embodiment, the present invention proposes a cable threading tube plugging device, including a card block 2 connected to the threading tube 1, the card block 2 is in an F shape, a screw rod 3 is plugged into the card block 2, one end of the screw rod 3 is located inside the threading tube 1, and a plugging block 6 is plugged in, the end of the screw rod 3 located inside the threading tube 1 is in a T shape, the T-shaped end of the screw rod 3 abuts against the plugging block 6, the end of the screw rod 3 away from the threading tube 1 is fixed with a butterfly cap 4, the plugging block 6 is in an arc shape, at least two plugging blocks 6 are provided, and the plurality of plugging blocks 6 are spaced apart from each other. The blocks 2 are symmetrically arranged or evenly spaced in a ring shape. A fastening nut 5 is provided at one end of the block 2 away from the sealing block 6. The fastening nut 5 is threadedly connected to the screw rod 3. When in use, the fastening nut 5 is rotated to drive the screw rod 3 to move outward, and the sealing block 6 is pulled to move by the screw rod 3, and the sealing block 6 is squeezed to make the sealing block 6 axially compressed and vertically expanded, so as to block the gap between the cable and the threading tube, realize sealing of the threading tube, effectively avoid water leakage of the threading tube, and have a good overall use effect.
