Description

Technical Field

[0001] This utility model belongs to the technical field of pipe elbow equipment, and in particular relates to an adjustable angle elbow. Background Technology

[0002] During pipeline construction, the elbows currently used are non-adjustable elbows, which require on-site surveying and repeated modifications, resulting in low efficiency. Furthermore, the angle cannot be adjusted arbitrarily, and the usage location is highly demanding. When connecting pipelines, the angle is finely adjusted by the curvature of the straight pipe, which makes the connection location prone to leakage. The installation is also unsightly and affects the standardization of the site. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable-angle elbow, which solves the problems of existing elbows that cannot be adjusted at will, are prone to leakage at the connection position, and are not aesthetically pleasing during installation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable-angle elbow includes a male component and a female component, both of which are arc-shaped pipes. The male component has an annular groove at its top periphery to prevent detachment, and a sealing ring of a corresponding size is fitted onto the groove. The female component has anti-detachment locking points on its inner periphery. The bottom end of the male component enters the pipe of the female component and fits with it. The female component slides within the groove of the male component.

[0006] Preferably, the curvature of the male connector is 35-75 degrees, and the curvature of the female connector is 35-75 degrees.

[0007] Preferably, a limiting ring is provided at the top of the male connector.

[0008] Preferably, a limiting ring is provided at the bottom end of the female head component.

[0009] The beneficial effects achieved by this utility model are as follows:

[0010] (1) By fitting the male and female parts together, the angle can be flexibly adjusted while ensuring the sealing performance through the slot and sealing ring. There will be no leakage, and there is no need for repeated measurement and modification, thus improving efficiency.

[0011] (2) The maximum and minimum angles are controlled by a limit ring;

[0012] (3) The elbow is easy to install and use, aesthetically pleasing, and has high structural reliability. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-3 As shown, an adjustable-angle elbow includes a male connector 1 and a female connector 2, both of which are arc-shaped pipes. The top of the male connector 1 is provided with a limiting ring 13, and the top of the outer periphery of the male connector 1 is provided with an annular groove 11. A sealing ring 12 of a corresponding size is fitted on the groove 11. The inner periphery of the female connector 2 has anti-detachment locking points 21. The male connector 1 inserts into the pipe of the female connector 2 and fits with the female connector 2. The female connector 2 slides within the groove 11 of the male connector 1. The bottom of the female connector 2 is provided with a limiting ring 22. The groove, locking points, and sealing rings combine to allow the female connector to slide within a fixed range without separating. When the desired angle is reached, the sealing ring locks the groove, achieving flexible angle adjustment. The limiting rings ensure the stability of the adjusted angle.

[0020] like Figure 4 As shown, the top of the female connector slides to the limiting ring of the male connector pipe, while the bottom of the male connector slides to the limiting ring of the female connector, reaching the minimum adjustable angle of 72 degrees. The top of the female connector slides to a certain point on the male connector, reaching its limit and being unable to move further. The sealing ring then locks the groove, reaching the maximum adjustable angle of 108 degrees.
