In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0026] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For the ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances. In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict between them.
[0027] As Figures 1 to 3The utility model discloses a self-rolling sleeve, including first weaving department 1, second weaving department 2 and third weaving department 3 who are connected with the both ends of first weaving department 1 respectively. First weaving department 1, second weaving department 2 and third weaving department 3 are integrally woven into shape, that is, first weaving department 1, second weaving department 2 and third weaving department 3 cooperate to form a cloth-like material made of weaving process, and the plane of the cloth-like material is rectangular. The cloth-like material can be self-rolled, specifically, the second weaving department 2 is curled towards the third weaving department 3, and the third weaving department 3 is curled towards the second weaving department 2. Finally, the second weaving department 2 and the third weaving department 3 overlap each other, and first weaving department 1, second weaving department 2 and third weaving department 3 cooperate with each other to form a tube. The utility model is different from the prior art in that the sum of the thickness of the second weaving department 2 and the thickness of the third weaving department 3 is equal to the thickness of the first weaving department 1, and the inner wall and the outer wall of the self-rolling sleeve of the utility model are both smooth curved surfaces. Therefore, when the self-rolling sleeve of the utility model is self-rolled, the second weaving department 2 and the third weaving department 3 overlap each other, the thickness of each part of the formed self-rolling sleeve is the same, and there is no step surface formed at the overlapping position on the inner wall and the outer wall of the self-rolling sleeve, so that the inner wall and the outer wall of the self-rolling sleeve of the utility model are relatively flat, and there is basically no gap between the inner wall of the self-rolling sleeve and the automobile wire harness after the automobile wire harness enters the self-rolling sleeve of the utility model, so that the automobile wire harness is tightly wrapped and is not easy to be separated.
[0028] As Figure 3 shown, since the self-rolling sleeve of the utility model forms a tube with a cross section in the form of a ring with a relatively gentle curvature after being self-rolled, the outer wall of the self-rolling sleeve has no obvious protrusions, and the self-rolling sleeve is convenient to arrange in the automobile. At the same time, since the thickness of each part of the self-rolling sleeve of the utility model is the same, the wear resistance of each part of the self-rolling sleeve is relatively balanced, and there is no relatively weak position, so that the self-rolling sleeve has good wear protection effect.
[0029] At the same time, the self-rolling sleeve of the utility model is provided with a first connecting part on the second weaving department 2 and a second connecting part matched with the first connecting part on the third weaving department 3. In the use process of the self-rolling sleeve of the utility model, the first connecting part and the second connecting part are first separated, and then the second weaving department 2 and the third weaving department 3 are separated. After the automobile wire harness is inserted into the self-rolling tube through the gap between the self-rolling sleeve, the second weaving department 2 and the third weaving department 3 are overlapped, and the first connecting part and the second connecting part are matched. Through the arrangement of the first connecting part and the second connecting part, the second weaving department 2 and the third weaving department 3 can be closely attached and quickly separated, and the automobile wire harness is not easy to be separated from the self-rolling sleeve.
[0030] The self-winding sleeve has many ways to realize the same wall thickness of each part, and the first connecting part and the second connecting part can also have many connecting ways.
[0031] In the embodiment, as shown in Figure 3 The thickness of the second weaving part 2 is equal to the thickness of the third weaving part 3. The self-winding sleeve of the utility model is manufactured by using the same material for the second weaving part 2 and the third weaving part 3, so that the manufacturing cost of the second weaving part 2 and the third weaving part 3 is reduced. In other embodiments, in order to facilitate the rapid overlap of the second weaving part 2 and the third weaving part 3, prevent the overlap position of the second weaving part 2 and the third weaving part 3 from being reversed, and cause the connection between the overlapping part of the second weaving part 2 and the third weaving part 3 and the first weaving part 1 to form a stepped surface, the thickness of the second weaving part 2 is greater than the thickness of the third weaving part 3, which is a foolproof design during use of the self-winding sleeve.
[0032] In the embodiment, as shown in Figures 1 to 3 The second weaving part 2 is arranged to form the outer wall of the self-winding sleeve of the utility model in cooperation with the first weaving part 1, the third weaving part 3 is arranged to form the inner wall of the self-winding sleeve of the utility model in cooperation with the first weaving part 1, the first connecting part is the protruding part 4, and the second connecting part is the recessed part 5. The second weaving part 2 and the third weaving part 3 are quickly connected and separated through the arrangement of the protruding part 4 and the recessed part 5. In the manufacturing process of the self-winding sleeve of the utility model, after the self-winding sleeve is woven, the protruding part 4 can be pressed out on the second weaving part 2 through a heat setting process, so that the second weaving part 2 has the protruding part 4 on one side and a groove on the other side. After the self-winding sleeve is completed, the outer wall of the self-winding sleeve has a groove formed by the heat setting process. At the same time, on the third weaving part 3, the third weaving part 3 is placed on a flat plate, and the recessed part 5 is pressed out from top to bottom through a heat setting process. Because the flat plate blocks the bottom of the third weaving part 3, the third weaving part 3 has the recessed part 5 on one side and is still a plane on the other side. After the self-winding sleeve is completed, the inner wall of the self-winding sleeve is a smooth curved surface. In other embodiments, the first connecting part is a first magic tape, and the second connecting part is a second magic tape matched with the first magic tape. After the second weaving part 2 and the third weaving part 3 are woven, the first magic tape is fixed on the second weaving part 2, and the second magic tape is fixed on the third weaving part 3.
[0033] In the embodiment, as shown in Figure 1 and Figure 2As shown, the convex pieces 4 and the concave pieces 5 are both provided with a plurality of pieces, and each convex piece 4 and each concave piece 5 are arranged in turn staggered. The utility model through the staggered arrangement of the convex pieces 4 and the concave pieces 5, facilitate the close fit of the second weaving part 2 and the third weaving part 3. In other embodiments, each convex piece 4 and each concave piece 5 are also arranged along a straight line.
[0034] In the embodiment, as shown, Figure 4 The first weaving part 1, the second weaving part 2 and the third weaving part 3 are all formed by cross staggered weaving of the warp 7 and the weft 6, and the first weaving part 1, the second weaving part 2 and the third weaving part 3 are integrally formed by weaving. The diameter of the weft 6 in the first weaving part 1, the weft 6 in the second weaving part 2 and the weft 6 in the third weaving part 3 are all the same. The diameter of the warp 7 in the second weaving part 2 and the diameter of the warp 7 in the third weaving part 3 are the same, and the diameter of the warp 7 in the first weaving part 1 is twice the diameter of the warp 7 in the second weaving part 2. The utility model makes the thickness of the first weaving part 1 woven is twice the thickness of the second weaving part 2 by setting the diameter of the warp 7 in the first weaving part 1 is twice the diameter of the warp 7 in the second weaving part 2. In other embodiments, when the thickness of the second weaving part 2 and the third weaving part 3 is inconsistent, the diameter of the warp 7 in the third weaving part 3 can also be different from the diameter of the warp 7 in the second weaving part 2.
[0035] In the embodiment, as shown, Figure 3 The angle of the overlapping part of the second weaving part 2 and the third weaving part 3 is 55° to 75°. That is, the cross section of the overlapping part of the second weaving part 2 and the third weaving part 3 forms an arc with an arc of 55° to 75°.
[0036] In the embodiment, the weft 6 is a single wire, and the warp 7 is a multifilament. Specifically, the weft 6 is a PET single wire, and the diameter of the single wire is 0.18 to 0.32 millimeters, and the warp 7 is a PET multifilament.
[0037] In summary, by setting the second weaving part 2 and the third weaving part 3 overlap, and setting the thickness of the second weaving part 2 and the thickness of the third weaving part 3 equal to the thickness of the first weaving part 1, so that the wall thickness of each part of the self-winding sleeve is equal, after the automobile wiring harness is assembled into the self-winding sleeve of the utility model, there is basically no gap between the inner wall of the self-winding sleeve and the automobile wiring harness, and the automobile wiring harness is tightly wrapped and not easy to be separated. And through the setting of the first connecting part and the second connecting part, the second weaving part 2 and the third weaving part 3 can be tightly attached and quickly separated, and the automobile wiring harness is not easy to be separated from the self-winding sleeve. And by setting the thickness of the second weaving part 2 equal to the thickness of the third weaving part 3, the manufacturing cost of the second weaving part 2 and the third weaving part 3 is reduced. And through the setting of the convex part 4 and the concave part 5, the second weaving part 2 and the third weaving part 3 can be quickly connected and separated. And through the staggered arrangement of the convex part 4 and each concave part 5, the second weaving part 2 and the third weaving part 3 can be tightly attached. By setting the diameter of the warp 7 in the first weaving part 1 twice the diameter of the warp 7 in the second weaving part 2, the thickness of the first weaving part 1 woven is twice the thickness of the second weaving part 2.
[0038] It should be emphasized that: the above is only the preferred embodiment of the utility model, not any form of the utility model, any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the utility model still belongs to the scope of the technical scheme of the utility model.
