Description

Technical Field

[0001] This utility model relates to the field of moisture-proof protective sleeve technology, and in particular to a corrugated telescopic busbar moisture-proof protective sleeve. Background Technology

[0002] Busbar trunking refers to the frame commonly used in power engineering to protect cables and wires. Corrugated telescopic moisture-proof sheaths are sheaths that are used in conjunction with busbar trunking and have a corrugated appearance. Because their length can be extended or retracted, they are more suitable for protecting cables and wires.

[0003] In practical applications, the existing corrugated telescopic moisture-proof cover has a relatively complete structure and function, which can meet basic usage requirements, but the following problems still exist:

[0004] In actual use, cables or wires are very prone to shaking inside the moisture-proof sheath, which causes the two ends of the cables or wires to retract into the moisture-proof sheath, thus affecting the use of cable and wire joints. At the same time, the cables or wires frequently slide inside the moisture-proof sheath. Since the moisture-proof sheath has a telescopic structure, it is very easy for the cable and wire joints to detach, which is very inconvenient.

[0005] Therefore, this utility model provides a corrugated telescopic busbar moisture-proof protective sleeve. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a corrugated telescopic busbar moisture-proof cover.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a corrugated telescopic busbar trunking moisture-proof sleeve, comprising a sleeve body, wherein a plurality of fixing rings are fixedly connected to the outer surface of the sleeve body, the fixing rings being arranged at equal intervals along the outer surface of the sleeve body; anti-slip connection structures are provided on both sides of the fixing rings, the anti-slip connection structures comprising annular plates, wherein a first annular plate is fixedly connected to the outer side of the annular plate, and a second annular plate is fixedly connected to the inner side of the annular plate, the second annular plate being located inside the first annular plate; and a plurality of auxiliary anti-slip structures are provided on the inner wall of the fixing rings, the plurality of auxiliary anti-slip structures being arranged at equal intervals along the inner wall of the fixing rings.

[0008] In a preferred embodiment, a plurality of first rectangular protrusions are fixedly connected to the inner surface of the first ring plate, and the plurality of first rectangular protrusions are arranged at equal intervals along the circumference of the first ring plate. A plurality of second rectangular protrusions are fixedly connected to the outer surface of the second ring plate, and the plurality of second rectangular protrusions are arranged at equal intervals along the circumference of the second ring plate. A fastening ring plate is fixedly connected to the other side of the ring plate. The fastening ring plate is made of rubber, and a plurality of third rectangular protrusions are fixedly connected to the inner surface of the fastening ring plate, and the plurality of third rectangular protrusions are arranged at equal intervals along the circumference of the fastening ring plate.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the first ring plate and the second ring plate, the two ends of the sleeve can be connected and limited by the first rectangular protrusion and the second rectangular protrusion. Under the action of the fastening ring plate and the third rectangular protrusion, the cable or wire passing through the sleeve can be limited.

[0010] In a preferred embodiment, a threaded extrusion rod is threadedly connected to the inner wall of the first ring plate. One end of the threaded extrusion rod is fixedly connected to an operating block, and the other end of the threaded extrusion rod is fixedly connected to a rubber round block.

[0011] The technical effect of adopting the above-mentioned further solution is that the operating block can drive the threaded extrusion rod to rotate, which in turn can drive the rubber block to move, which in turn can drive the rubber block to extrude and fix the sleeve, so that the annular plate and other structures can be limited and fixed with the sleeve.

[0012] In a preferred embodiment, the auxiliary anti-slip structure includes a plurality of auxiliary ring plates, the auxiliary ring plates being made of rubber, the plurality of auxiliary ring plates being arranged at equal intervals along the inner surface of the sleeve, and a plurality of circular protrusions being fixedly connected to the inner surface of the auxiliary ring plates, the circular protrusions being made of rubber, the plurality of circular protrusions being arranged at equal intervals along the inner wall of the auxiliary ring plates.

[0013] The technical effect of adopting the above-mentioned further solution is that the auxiliary ring plate can cooperate with the circular protrusion to assist in limiting the cable or wire located inside the sleeve, thereby preventing the cable or wire from frequently swinging and shaking inside the sleeve, which could lead to the end detaching.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting an anti-slip connection structure, the annular plate and the sleeve can be connected. Under the action of the threaded extrusion rod, the rubber block can be moved, so that the annular plate can be firmly connected to the sleeve. This, together with the fastening annular plate and the third rectangular protrusion, can provide auxiliary restraint for both ends of the wires or cables inserted into the sleeve, thereby preventing the cables or wires from retracting into the sleeve and affecting use. By setting an auxiliary anti-slip structure, under the action of the auxiliary annular plate and the circular protrusion, the friction between the inner wall of the sleeve and the outer surface of the cable or wire can be increased, thus making the cable or wire more firmly inserted into the inner wall of the sleeve, preventing frequent shaking that could cause the sleeve to detach from the cable or wire.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4As shown, this embodiment provides a technical solution: a corrugated telescopic busbar trunking moisture-proof sleeve, including a sleeve body 1. A plurality of fixing rings 2 are fixedly connected to the outer surface of the sleeve body 1, and the fixing rings 2 are arranged at equal intervals along the outer surface of the sleeve body 1. Anti-slip connection structures 3 are provided on both sides of the fixing rings 2. The anti-slip connection structure 3 includes an annular plate 31. A first annular plate 32 is fixedly connected to the outer side of the annular plate 31, and a second annular plate 33 is fixedly connected to the inner side of the annular plate 31, with the second annular plate 33 located inside the first annular plate 32. A plurality of auxiliary anti-slip structures 4 are provided on the inner wall of the fixing rings 2, and the plurality of auxiliary anti-slip structures 4 are arranged at equal intervals along the inner wall of the fixing rings 2. By providing the anti-slip connection structures 3, the annular plate 3... 1. Connect to the sleeve 1, and under the action of the threaded extrusion rod 38, drive the rubber block 310 to move, so that the annular plate 31 can be firmly connected to the sleeve 1. Then, in conjunction with the fastening ring plate 36 and the third rectangular protrusion 37, the two ends of the wire or cable inserted inside the sleeve 1 can be auxiliaryly limited, so as to prevent the cable or wire from shrinking into the inside of the sleeve 1 and affecting the use. By setting the auxiliary anti-slip structure 4, under the action of the auxiliary ring plate 41 and the circular protrusion 42, the friction between the inner wall of the sleeve 1 and the outer surface of the cable or wire can be increased, so that the cable or wire can be more firmly inserted into the inner wall of the sleeve 1, and frequent shaking will prevent the sleeve 1 from detaching from the cable or wire.

[0026] Going a step further, such as Figures 2-3 As shown: A plurality of first rectangular protrusions 34 are fixedly connected to the inner surface of the first ring plate 32. The plurality of first rectangular protrusions 34 are arranged at equal intervals along the circumference of the first ring plate 32. A plurality of second rectangular protrusions 35 are fixedly connected to the outer side of the second ring plate 33. The plurality of second rectangular protrusions 35 are arranged at equal intervals along the circumference of the second ring plate 33. A fastening ring plate 36 is fixedly connected to the other side of the ring plate 31. The fastening ring plate 36 is made of rubber. A plurality of third rectangular protrusions 37 are fixedly connected to the inner surface of the fastening ring plate 36. The plurality of third rectangular protrusions 37 are arranged at equal intervals along the circumference of the fastening ring plate 36. Under the action of the first ring plate 32 and the second ring plate 33, the first rectangular protrusions 34 and the second rectangular protrusions 35 can be used to connect and limit the two ends of the sleeve 1. Under the action of the fastening ring plate 36 and the third rectangular protrusions 37, the cables or wires passing through the sleeve 1 can be limited.

[0027] The above solution also has the problem of unstable engagement between the first ring plate 32 and the second ring plate 33 and the inner wall of the sleeve 1, such as... Figure 2As shown: In this scheme, the inner wall of the first ring plate 32 is threadedly connected to a threaded extrusion rod 38. One end of the threaded extrusion rod 38 is fixedly connected to an operating block 39, and the other end of the threaded extrusion rod 38 is fixedly connected to a rubber block 310. The operating block 39 can drive the threaded extrusion rod 38 to rotate, which in turn can drive the rubber block 310 to move, which in turn can drive the rubber block 310 to extrude and fix the sleeve 1, so that the ring plate 31 and other structures can be limited and fixed with the sleeve 1.

[0028] The above solutions also have the problem that the cable or wire tends to move frequently within the inner wall of sleeve 1, leading to detachment at both ends. Figure 4 As shown, the auxiliary anti-slip structure 4 includes several auxiliary ring plates 41. The auxiliary ring plates 41 are made of rubber. The several auxiliary ring plates 41 are arranged at equal intervals along the inner surface of the sleeve 1. Several circular protrusions 42 are fixedly connected to the inner surface of the auxiliary ring plates 41. The circular protrusions 42 are made of rubber. The several circular protrusions 42 are arranged at equal intervals along the inner wall of the auxiliary ring plates 41. The auxiliary ring plates 41 can cooperate with the circular protrusions 42 to assist in limiting the cable or wire located inside the sleeve 1, thereby preventing the cable or wire from frequently swinging and shaking inside the sleeve 1, which could cause the end to detach.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] When in use: insert the sleeve 1 between the first ring plate 32 and the second ring plate 33, and then the sleeve 1 can be firmly locked by the action of the first rectangular protrusion 34 and the second rectangular protrusion 35. At this time, the threaded extrusion rod 38 can be rotated so that the threaded extrusion rod 38 can drive the rubber block 310 to move, thereby assisting in fixing the sleeve 1.

[0032] At this time, the cable or wire can be inserted into the fastening ring plate 36, and then the cable or wire can be assisted in being limited by the third rectangular protrusion 37.

[0033] At this time, the cable and wire are inside the sleeve 1, and under the action of the auxiliary ring plate 41 and the circular protrusion 42, the friction is increased and the fixation is made more stable.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
