Abstract

The utility model discloses an aluminum alloy section and belongs to the technical filed of building materials, which comprises a hollow strip-shaped body formed by connecting a left side wall, a right side wall and an upper wall. The lower portion of the hollow strip-shaped body is in an opening shape. The middle of the upper wall is an outer circular arc-shaped portion, a clamping groove is arranged at one end of the upper wall close to the position of the left side wall, and the other end of the upper wall is connected with the right side wall through a groove. The lower end of the left side wall extends towards the inside of the body in vertical bending mode to form a blocking edge. A T-shaped clamping groove is arranged on the outer side of the lower end of the right side wall. By means of the clamping grooves arranged on the side walls and the upper wall of the body, the aluminum alloy section is conveniently used by being assembled with other aluminum alloy section structures. Simultaneously, the aluminum alloy section has simple structure, small manufacturing mould and low manufacturing cost.

Description

A kind of aluminium alloy extrusions

Technical field

The utility model relates to a kind of aluminium alloy extrusions, relates in particular to a kind of aluminium alloy extrusions that is used to make door and window, belongs to building material technical field.

Background technology

Aluminium alloy extrusions since have attractive in appearance, lightly reach advantages such as durable, already obtained being widely used at building decoration, especially on door and window, use more general.Yet the structure of existing aluminium alloy extrusions is often bigger, not only needs bigger casting die, and cost of manufacture is high, and between the section bar of different structure, can not be according to actual needs and flexible combination is used, therefore, use inconvenient.

The utility model content

The technical problem that the utility model will solve provides a kind of simple in structure, aluminium alloy extrusions of being convenient to assemble.

For solving the problems of the technologies described above, the utility model is taked following technical scheme:

The aluminium alloy extrusions that the utility model provides comprises hollow bar shaped body, and said body is connected to form by left side wall, right side wall and upper wall, and the bottom is opening-like; The middle part of said upper wall is the cylindrical arcus part, and an end of this upper wall is provided with draw-in groove near the left side wall place, and the other end is connected with right side wall through a groove; The vertical bending in body of said left side wall lower end extends to form a rib; Said right side wall lower outside is provided with T type draw-in groove.

According to a kind of preferred implementation of above-mentioned aluminium alloy extrusions, wherein, an end of the cylindrical arcus part of said upper wall stretches into body interior and forms a rib to extending below.

The aluminium alloy extrusions that the utility model provides is provided with draw-in groove through sidewall and lower wall at body, and convenient the assembling with other aluminium alloy extrusions structure used, and simultaneously, because the utility model is simple in structure, it is little to make mould, and cost of manufacture is low.

Description of drawings

In order to be illustrated more clearly in the utility model patent working example or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model patent, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of the utility model aluminium alloy extrusions.

The specific embodiment

The accompanying drawing that will combine the utility model below carries out clear, intactly description to the technical scheme of the utility model, and obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, the embodiment of the aluminium alloy extrusions that the utility model provides comprises hollow bar shaped body, and said body is connected to form by left side wall 11, right side wall 12 and upper wall, and the bottom is opening-like; The middle part of said upper wall is a cylindrical arcus part 14, and an end of this upper wall is provided with draw-in groove 15 near left side wall 11 places, is used for being connected with the aluminium alloys fastener 30 of coupling; The other end is connected with right side wall 12 through a groove 16; The vertical bending in body of said left side wall 11 lower ends extends to form a rib 17; Said right side wall 12 lower outside are provided with T type draw-in groove 18, are used for being connected with the aluminium alloy type equipment structure of coupling.

Wherein, an end of the cylindrical arcus part 14 of said upper wall stretches into body interior and forms a rib 20 to extending below.

The aluminium alloy extrusions that the utility model provides is provided with draw-in groove 15 through the upper wall 13 at body, and right side wall 12 lower ends are provided with T type draw-in groove 18; The convenient assembling with other aluminium alloy extrusions structure used, simultaneously, because the utility model is simple in structure; The making mould is little, and cost of manufacture is low.

The above; Be merely the specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion by said protection domain with claim.

Claims
