Description

Z-shaped air bus duct

Technical Field

The utility model relates to a bus duct technical field, concretely relates to Z type air bus duct.

Background

The bus duct is a closed metal device, generally consists of a copper bus post and an aluminum bus post, is used for distributing larger power for each element in a dispersion system, gradually replaces wires and cables, and is widely applied; the Z-shaped bus duct is bent in shape, and if the integrally formed Z-shaped bus duct is used, the assembling process is difficult, so that the end shell is fixed on the middle shell by screws in the Z-shaped bus duct in the prior art to form a Z-shaped structure.

For example, a zigzag bus duct disclosed in chinese patent application No. CN202122788211.4 includes a middle housing and two end housings. The middle section shell is provided with a first inclined plane at two ends, and one end of the end part shell is provided with a second inclined plane; although this patent passes through the screw with middle section casing, the tip casing is fixed together, has simple structure and easy advantage of equipment, but this patent need aim at the inclined plane of middle section casing, tip casing, then utilizes screw nut spare to hug closely two connecting plates connection fixed together closely together to accomplish the equipment, in actual assembly process, do not aim at the inclined plane of middle section casing and tip casing easily, influenced the equipment convenience of Z type busway.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a simple structure, the Z type air bus duct of the convenient equipment.

In order to solve the technical problem, the technical scheme of the utility model is that: a Z-shaped air bus duct comprises a middle section shell and end part shells fixed at two ends of the middle section shell by screws, wherein the middle section shell and the two end part shells are connected to form a Z-shaped structure; openings are formed in two ends of the middle section shell, and the middle section shell is provided with a through hole which is located in the side wall of the opening and is communicated with the opening; one end of the end shell facing the middle shell is provided with an insertion part, and the insertion part is provided with a threaded hole corresponding to the position of the through hole; and the end shell is arranged on the middle shell by passing a screw through the through hole and being in threaded connection with the threaded hole.

Preferably, a plurality of first heat dissipation strips which are arranged at equal intervals are arranged on two outer walls of the middle section shell respectively facing the two end part shells; the outer surface area of the middle section shell is increased through the first heat dissipation strips, and the heat dissipation capacity of the middle section shell is improved.

Preferably, a plurality of second heat dissipation strips are arranged on the outer walls of the top and the bottom of the end part shell; the outer surface area of the end part shell is increased through the second heat dissipation strips, and the heat dissipation capacity of the middle shell is improved.

Preferably, a buffer layer is arranged on the outer wall of the insertion part of the end shell; the buffer layer can play a role in buffering between the outer wall of the insertion part and the inner wall of the opening, and sealing capacity of the end part shell fixed behind the middle section shell through screws is improved.

Further, the buffer layer is a rubber buffer layer.

The utility model discloses technical effect mainly embodies: through inserting the opening to the portion of inserting, the rethread screw passes the through-hole to carry out threaded connection with the screw hole, just can install the tip casing to the middle section casing on, have simple structure and the advantage of the equipment of being convenient for.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so as to make the technical solutions of the present invention easier to understand and grasp.

In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.

A Z-shaped air bus duct is shown in figures 1-3 and comprises a middle section shell 1 and end part shells 2 fixed to two ends of the middle section shell 1 through screws, wherein the middle section shell 1 and the two end part shells 2 are connected to form a Z-shaped structure. The both ends of middle section casing 1 are provided with opening 11, middle section casing 1 be provided with be located opening 11's lateral wall and with the through-hole 12 of opening 11 intercommunication, the first heat dissipation strip 13 of a plurality of that is provided with the equidistance range respectively on two outer walls of two tip casings 12 of middle section casing 1. The external surface area of the middle section shell 1 is increased through the first heat dissipation strips 13, and the heat dissipation capacity of the middle section shell 1 is improved.

The end of the end housing 2 facing the middle housing 1 is provided with an insertion portion 21, and the insertion portion 11 is provided with a threaded hole 22 corresponding to the position of the through hole 12. The end shell 2 is mounted to the middle shell 1 by screws 3 passing through the through holes 12 and being screwed into the threaded holes 22. And a plurality of second heat dissipation strips 23 are arranged on the outer walls of the top and the bottom of the end shell 2.
