Description

Technical Field

[0001] The utility model belongs to the technical field of protective covers, and specifically relates to a zippered telescopic protective cover. Background Art

[0002] There are wire harness assemblies distributed inside the body of an automobile. The wire harness assembly contains multiple signal lines and power lines. Usually, cable ties are used to bundle multiple wires together to avoid mess and facilitate layout. However, the cable ties are relatively thin and cannot protect the wire harness while bundling, preventing the wire harness from touching and rubbing against body components. Tight bundling with cable ties will cause local compression on the wire harness and affect signal transmission, lacking appropriate pre-tightening force. To solve this problem, a zippered telescopic protective cover is provided. Summary of the Utility Model

[0003] In view of this, the technical problem to be solved by the utility model is to provide a zippered telescopic protective cover, which solves the problems that cable ties in the prior art cannot protect the wire harness and lack pre-tightening force.

[0004] To solve the above technical problem, the utility model discloses a zippered telescopic protective cover, including: a protective cover body and a zipper sliding member; the protective cover body is in a sheet shape, and its opposite edges are respectively provided with a card slot and a card protrusion. The card slot and the card protrusion are matched by the zipper sliding member to make the protective cover body in a tubular shape. The protective cover body is provided with wave pleats, and limit grooves are respectively formed with the ridges extending from the back of the card slot and the card protrusion. The zipper sliding member is matched with the limit grooves.

[0005] Further, at least two wave-peak-shaped wave pleats are provided on the wave pleats.

[0006] Further, the wave pleats have a first wave pleat and a second wave pleat. The first wave pleat respectively forms limit grooves with the ridges extending from the back of the card slot and the card protrusion. The inner gap of the first wave pleat is smaller than the inner gap of the second wave pleat.

[0007] Further, the cross-section of the limit groove is in the shape of a small opening and a wide inner cavity.

[0008] Further, barb portions are provided on the upper and lower sides of the card protrusion.

[0009] Further, barb portions are provided on the inner walls on both sides of the card slot.

[0010] Compared with the prior art, the present application can obtain the following technical effects:

[0011] The utility model can form a tube sleeve shape through the cooperation of the card slot and the card convexity, which plays the role of bundling and protecting multiple wire harnesses. The wavy pleats play a telescopic role. After being expanded, the diameter of the tube sleeve becomes larger and more wire harnesses can be bundled. The pre-tightening force on the bundled wire harnesses can avoid local compression and also play the role of tight wrapping. The limiting groove on the tube sleeve can clamp the wire harness outside the tube sleeve, and can also clamp the fixed bracket to facilitate the positioning of the tube sleeve on the vehicle body.

[0012] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The drawings described herein are used to provide a further understanding of the present application and constitute a part of the present application. The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute an improper limitation on the present application. In the drawings:

[0017] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figure 1 , Figure 1 It is a cross-sectional schematic diagram of a protective cover according to one embodiment of the utility model.

[0019] A zipper-type retractable protective cover comprises: a protective cover body 1 and a zipper slider; the protective cover body 1 is in the shape of a sheet, and its opposite edges are respectively provided with a card slot 2 and a card protrusion 3, the card slot 2 and the card protrusion 3 are matched by the zipper slider so that the protective cover body 1 is in the shape of a tube sleeve, a wavy pleat portion is provided on the protective cover body 1, and a limiting groove 5 is formed with a convex strip 4 extending from the back of the card slot 2 and the card protrusion 3 respectively, the zipper slider cooperates with the limiting groove 5, the cooperation between the card slot 2 and the card protrusion 3 is like the strip teeth on both sides of the zipper, the zipper slider cooperates with the limiting groove 5 on the back of the card slot 2 and the card protrusion 3, and the zipper slider is moved to press the card protrusion 3 into the card slot 2.

[0020] The wavy pleat part has two wave-peak-shaped wavy pleats, namely the first wavy pleat 6 and the second wavy pleat 7. The first wavy pleat 6 respectively forms a limiting groove 5 with the clamping groove 2 and the rib 4 extending from the back of the clamping protrusion 3. The inner gap of the first wavy pleat 6 is smaller than the inner gap of the second wavy pleat 7; the cross-section of the limiting groove 5 is in the shape of a small opening and a wide inner cavity; barb parts are provided on the upper and lower sides of the clamping protrusion 3, and barb parts are provided on the inner walls on both sides of the clamping groove 2.

[0021] In summary, the utility model can form a tube sleeve shape through the cooperation of the clamping groove 2 and the clamping protrusion 3, playing a role in bundling and protecting multiple wire harnesses. The wavy pleat part plays a role in expansion and contraction. After being expanded, the diameter of the tube sleeve becomes larger, enabling it to bundle more wire harnesses. It has a pre-tightening force on the bundled wire harnesses, which can not only avoid local compression but also play a role in tightly wrapping. The limiting groove 5 on the tube sleeve can clamp the wire harness outside the tube sleeve or can be clamped to a fixed bracket to facilitate the positioning of the tube sleeve on the vehicle body.

[0022] The above description shows and describes several preferred embodiments of the utility model. However, as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the inventive concept described herein through the above teachings or the technology or knowledge in related fields. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the utility model shall fall within the protection scope of the appended claims of the utility model.
