Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the utility model provides a dampproofing protection device of cable incision, including shrinkage pillar 10, stay tube 20 and incision sheath 30, shrinkage pillar 10 cladding in stay tube 20 is outside, just the length of stay tube 20 is greater than the length of shrinkage pillar 10, shrinkage pillar 10 is formed by connecting silicon rubber elasticity pipe 11 and external screw thread pipe 12, the inner wall of incision sheath 30 is provided with the first internal thread 31 with shrinkage pillar 10 looks interlock, just the one end of stay tube 20 stretches out external screw thread pipe 12 is connected with incision sheath 30 detachable.
The embodiment of the utility model provides a design principle is based on the crust that the elastic retraction power of silicon rubber elasticity pipe 11 compressed the cable conductor in the shrinkage pillar 10, realizes the notched sealed protection of cable, compares in traditional sticky tape parcel, and the leakproofness is stronger, and difficult wearing and tearing can effectively avoid in the moisture gets into the cable incision.
Be different from traditional cold shrink pipe and be through taking a percentage its inside plastics helical strip of pull in order to realize the back of contracting of silica gel elasticity pipe, the utility model discloses cold shrink pillar 10's of embodiment theory of operation does:
firstly, the support tube 20 is arranged in the cold-shrink protective tube 10, the silicone rubber elastic tube 11 in the cold-shrink protective tube 10 is pre-expanded through the support tube 20, then the cut end of the cable is extended inwards along the support tube 20, and because one end of the support tube 20 is connected with the cut sheath 30, the support tube 20 can be simultaneously driven to be pulled out from the cold-shrink protective tube 10 through the process that the cut sheath 30 is unscrewed outwards along the cold-shrink protective tube 10, and the sheath of the cable is pressed by the elastic retraction force of the silicone rubber elastic tube 11.
At the moment, only the tight fit between the silicon rubber elastic tube 11 and the cable sheath is realized, and the cut of the cable is still exposed outside, so that after the support tube 20 is completely drawn out from the cold-shrink protective tube 10, the support tube 20 and the cut sheath 30 are disassembled, the cut sheath 30 is rotatably installed on the cold-shrink protective tube 10 to cover the cut of the cable, the sealing protection of the cut of the cable is realized, the problem that the traditional plastic spiral strip is not easy to draw out is also solved, meanwhile, the detachable connection between the cut sheath 30 and the cold-shrink protective tube 10 can observe the internal condition of the cable joint at any time, and the cut sheath 30 can be reused.
In the above operation process, the detachable connection manner of the incision sheath 30 and the support tube 20 is that a cylindrical groove 32 is formed in the incision sheath 30, a second internal thread 33 is formed on the inner wall of the cylindrical groove 32, the rotation direction of the second internal thread 33 is opposite to that of the first internal thread 31, and the end of the support tube 20 is screwed through the threaded joint 22 and the cylindrical groove 32.
In a further preferred embodiment, a handle 34 is connected to an end surface of the incision sheath 30 to facilitate the rotational force of the incision sheath.
Simultaneously, in order to guarantee the laminating degree of silicon rubber elastic tube 11 and cable sheath, further avoid moisture to get into inside the cable, can silicon rubber elastic tube 11 keeps away from the one end inner wall subsides of incision sheath 30 are equipped with round water-swelling adhesive tape 111, and after the gap department of silicon rubber elastic tube 11 and cable sheath had the moisture infiltration, water-swelling adhesive tape 111 took place to expand to guarantee inside the unable cable that gets into of moisture.
In addition, in the present embodiment, the support tube 20 may be a hollow cylinder, or may also be a structure of a conventional plastic helical strip, specifically, the support tube 20 is helical, and each turn of the support tube 20 is adhered to each other, and a tap 21 is disposed at an end of the support tube 20 away from the external threaded tube 12.
When the conventional plastic spiral strip structure is adopted, the support tube 20 can be drawn out by using the tap in the use process of the cold-shrink protection tube 10, and once the drawing is not smooth or the spiral strip is broken, the support tube is driven to be drawn out by adopting the rotation mode of the incision sheath 30.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
