Abstract
The utility model discloses a special-shaped rectangular tube which comprises a tube body. Four corners at butt joint heads of two ends of the tube body are R-shaped corners, and the end face of the butt joint head at one end of the tube body is bigger than that of the butt joint head at the other end of the tube body. The special-shaped rectangular tube has the advantages that tube body connection is firm, and the special-shaped rectangular tube is convenient to assemble and disassemble.
Description
Technical field
The utility model relates to metal tube processing technique application, particularly a kind of special-shaped square quarter bend.
Background technique
The mode of production of special-shaped square quarter bend adopts traditional high-frequency welding manner always, yet the square tube that this mode is processed docking needs electric welding, dock not tight, easy cracking, and join strength is poor, docking mode is loaded down with trivial details.
Summary of the invention
The purpose of this utility model is in order to address the above problem, to have designed a kind of special-shaped square quarter bend.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of special-shaped square quarter bend comprises body, and four angles of butt joint place at body two ends all are R shape angle, and the end face of an end butt joint is greater than the end face of the other end butt joint.
Described R shape angle is to be connected and composed by an end of left semicircle and recessed arc-shaped edges to the right.
Described body is made by hot-strip or galvanized steel.
Utilize the special-shaped square quarter bend of the technical solution of the utility model making, in butt joint place of body, adopt the design of R shape angle, docking intensity is large, be not easy to occur to become flexible, and docking mode is simple, uses very convenient.
Description of drawings
Fig. 1 is the structural representation of special-shaped square quarter bend described in the utility model;
Fig. 2 is the structural representation of butt joint described in the utility model;
Fig. 3 is the connection diagram of special-shaped square quarter bend described in the utility model;
Among the figure, 1, body; 2, butt joint; 3, left semicircle; 4, arc-shaped edges.
Embodiment
Below in conjunction with accompanying drawing the utility model is specifically described, the structural representation of special-shaped square quarter bend described in the utility model such as Fig. 1, Fig. 2 is the structural representation of butt joint described in the utility model, as shown in the figure, a kind of special-shaped square quarter bend, comprise body 1, four angles at butt joint 2 places at body two ends all are R shape angle, and the end face of an end butt joint is greater than the end face of the other end butt joint.Wherein, described R shape angle is to be connected and composed by an end of left semicircle 3 and recessed to the right arc-shaped edges 4; Described body is made by hot-strip or galvanized steel.
The characteristics of the technical program are by the modification to injection mould, and R shape angle is processed at four angles of the butt joint of body, and the intensity of butt joint has obtained reinforcement.In use, to connecting, after being under pressure, the R shape corner structure of butt joint place can be born pressure with the butt joint between the body, ensures the stability of docking structure, and removes also very easy.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; some changes that those skilled in the art may make some part have wherein all embodied principle of the present utility model, belong within the protection domain of the present utility model.
