Hermetic protecting sleeve of vehicle pipeline bundle passing hole

Abstract

The invention relates to a hermetic protecting sleeve of a vehicle pipeline bundle passing hole, comprising a passing hole plate, a passing hole and a blocking plate, wherein the passing hole is located in the middle of the passing hole plate; a through hole coordinating with a pipeline bundle is arranged on the blocking plate; the blocking plate is provided with at least one through hole; a locking bar is mounted at the passing hole; the locking bar is a banded elastic element with the same sections on two ends; length of the locking bar is equal to circumference of an inner edge of the passing hole; a radial section of the locking bar is provided with a passing hole plate trough and a blocking plate trough which are opposite to each other; the passing hole plate trough and the blocking plate trough respectively have an U-shaped opening; width of the passing hole plate trough is corresponding to thickness of the passing hole plate; and width of the blocking plate trough is corresponding to thickness of the blocking plate. When a plurality of pipeline bundles or profiled pipeline bundles pass through the same one open hole, the pipeline bundles are hermetically protected and fixedly planned so as to avoid pipeline bundles movably swinging and contacting with each other at the passing hole, therefore, general utilization of products is significantly increased; amount and production cost of formed protecting sleeves are effectively reduced; structure is simple; and the protecting jacket is implemented easily.

Description

technical field [0001] The present invention relates to a sealing protective sleeve for the through hole of the vehicle pipeline bundle, which is especially suitable for one or a combination of the following situations: multiple wire harnesses and tube bundles pass through the same opening; the wiring harness or tube bundle through holes need to be sealed and fixed, such as It is not advisable to contact each other; special-shaped tube harnesses and components such as connectors or joints with large cross-sections at the front end or in the middle of the harness or tube bundles, resulting in the space for the through holes of the wire harness or tube bundles to be larger than the cross-section at the through hole after it is fixed. Background technique [0002] At present, with the development of the automobile industry, the application of wire harnesses and tube bundles in vehicles is more common, and the requirements for the protection and sealing of the through-holes of th...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects and deficiencies in the prior art that the through-hole sheath of the pipeline bundle does not have versatility, and cannot protect, fix and seal multiple pipeline bundles or multiple special-shaped pipeline bundles. A sealing sheath for the through-hole of a pipeline bundle of a vehicle, which is versatile and capable of planning and fixing the position of the through-hole for multiple pipeline bundles or multiple special-shaped pipeline bundles in the same through-hole and ensuring the sealing effect at the through-hole. In order to reduce the types and specifications of vehicle sheaths, reduce the number of vehicle through holes, avoid the contact between the pipeline bundles at the through holes, and realize the sealing and planning and fixing of the through holes
