Description

Multichannel pencil fixed stay frame

Technical Field

The utility model belongs to aviation electrical installation field relates to a multichannel pencil fixed stay to two flange structure.

Background

When the wiring of the airplane is designed, the main wiring harness channel is laid through the frame edge of the airplane structure, and when the airplane structure is in a single-flanging mode, a conventional wiring harness fixing and supporting mode is adopted; when the aircraft structure is in a double-flanging form, the wire harness needs to be fixed on the structural web plate, the double flanging at the front end of the web plate forms a wire harness fixing obstacle, when the number of the wire harnesses is small, a specially-made or combined support and clamp can be used for fixing, and when the number of the wire harnesses is large and the diameters of the wire harnesses are not the same, the double-flanging structure forms a great obstacle for fixing the wire harness. Such as: a certain main wiring harness channel on the airplane penetrates through the double-flanging frame edge of the structure, a plurality of specially-made parts and hoops with different sizes are used, the form is complex, and inconvenience is brought to design.

Disclosure of Invention

The utility model provides a demand and the problem that prior art exists that aim at according to aircraft development and production provide a multichannel pencil fixed stay to two turn-ups structures.

The utility model provides a multichannel pencil fixed stay frame, contains support body and a plurality of ply-yarn drill, its characterized in that, the support body be a cell type structure, be the obstacle in the cell type and dodge the chamber, it has the auricle to extend on the cell wall of one side, has the connecting hole on the auricle, the outside of opposite side cell wall is fixed with a plurality of ply-yarn drills.

The lower part of the line clamp is flat, the line clamp is hollow, and the upper part of the line clamp is concave in a saddle shape.

The bottom of the line card is hinged to the outer side of the groove wall, so that the saddle-shaped direction of the line card is adjustable.

The saddle-shaped recess of the line card is matched with the diameter of the wire harness.

Two lugs extend from the wall of the groove at one side of the supporting body. Each lug is provided with two connecting holes.

The utility model provides a multichannel pencil fixed stay easily installs to can reach the purpose of fixed and isolation pencil according to actual line footpath adjustment support position.

The utility model has the advantages that: the utility model discloses a support body and aircraft structural connection and provide smooth installation ply-yarn drill, set up rotatable ply-yarn drill in a flexible way according to pencil actual conditions, its simple to operate, environmental suitability is good, and the pencil is reliable fixed, can also realize that the main entrance pencil keeps apart.

The present application is described in further detail below with reference to the accompanying drawings of embodiments.

Drawings

Fig. 1 is a structural schematic diagram of a multi-channel wire harness fixing support.

Fig. 2 is a schematic diagram of the use of a multi-channel harness mounting support.

The numbering in the figures illustrates: the structure comprises a support body 1, a wire clamp 2, an avoiding cavity 3, a lug 4, a connecting hole 5, a binding belt 6, a wire harness 7 and a double-flanging web plate 8.

Detailed Description

Referring to fig. 1, the multichannel pencil fixed stay of this application contains support body 1 and a plurality of ply-yarn drill 2, its characterized in that, support body 1 be a cell type structure, be the obstacle in the cell type and avoid chamber 3, it has auricle 4 to extend on the cell wall of one side, has connecting hole 5 on the auricle 4, the outside of the cell wall of opposite side is fixed with a plurality of ply-yarn drills 2. The lower part of the line clamp 2 is flat, the line clamp is hollow, and the upper part of the line clamp is concave in a saddle shape. The bottom of the line card 2 is hinged to the outer side of the groove wall of the support body 1, so that the saddle-shaped direction of the line card 2 is adjustable. The saddle-shaped recess of the line card 2 is matched with the diameter of the wiring harness 7.

In the embodiment, two lugs 4 extend from a side wall of the supporting body 1. Each tab 4 has two attachment holes 5.

The using state is as shown in figure 2, the diameter and the number of the wire harnesses are fixed according to needs, the wire clamps 2 corresponding to the diameter and the number of the wire harnesses are fixed on the supporting body 1 of the multi-channel wire harness fixing support frame, the supporting body is fixed on a double-flanging web structure 8 of the airplane through the lug plates 4 and the connecting holes 5, the edge of the double-flanging web structure 8 is wrapped in the avoiding cavity 3 of the supporting body 1, and the wire harnesses 7 are fixed through the inner cavity of the wire clamps 2 through the binding belt 6.
