Detailed Implementation

[0023] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0024] refer to Figures 1 to 4

[0025] A multi-angle adjustable connector structure includes a main connector 10, on the lower side of which is provided a rod connecting part 11 for connecting with a vertical rod. Both sides of the main connector are rotatably connected to side connectors 20 with adjustable and lockable rotation angles, so that they can be locked after being adjusted to the required angle. The free end of the side connector is provided with an end structure for inserting into a pipe.

[0026] In this embodiment, to better connect with the end of the vertical member, a lower protrusion is provided on the lower side of the main connector, and an upper recess 12 is provided on the lower end surface of the lower protrusion to form a member connection portion. A threaded hole 13 is vertically provided in the upper recess. The end of the vertical member is inserted into the upper recess, and the connection is achieved by the screw installed on the vertical member engaging with the threaded hole.

[0027] In this embodiment, the upper concave portion is hemispherical so that the end of the vertical rod can be better recessed into the upper concave portion.

[0028] In this embodiment, both sides of the main connector are provided with outwardly protruding first connecting portions 14. The two first connecting portions on the main connector are staggered, that is, the first connecting portion at one end is forward and the first connecting portion at the other end is backward, which helps to ensure that the side connectors are located on the same plane. The side connector is provided with a second connecting portion 21 that is attached to the first connecting portion and is provided with an anti-rotation structure. The locking bolt 22 passes longitudinally through the first connecting portion and the second connecting portion and is locked by the nut 23. Thus, the side connector is locked after the angle is adjusted.

[0029] In this embodiment, the anti-rotation structure includes convex teeth 24 spaced apart along the circumferential direction on the end faces of the first connecting part and the second connecting part that are in contact with each other. The convex teeth of the first connecting part and the convex teeth of the second connecting part mesh with each other, which helps to ensure that the main connecting part and the side connecting part are locked better.

[0030] In this embodiment, the first connecting part is provided with an internal hexagonal countersunk groove 15 for limiting the nut to prevent the nut from rotating; the second connecting part is provided with a countersunk hole 25 for locking the bolt end to be inserted, thereby improving the overall aesthetics.

[0031] In this embodiment, a first triangular portion 16 facing the second connecting portion is provided on the side of the main connector corresponding to the second connecting portion, and a second triangular portion 26 facing the first connecting portion is provided on the side of the side connector corresponding to the first connecting portion. By having the upper and lower sides of the first and second triangular portions as inclined planes, a larger angle adjustment can be achieved, making the included angle between the main connector and the side connector smaller, down to a minimum of 45 degrees.

[0032] In this embodiment, in order to better connect with the pipe fitting, the end structure includes a pipe portion 27 disposed on the free end of the side connector, and the upper side and / or lower side of the pipe portion are provided with positioning holes 28 for positioning and engagement with the pipe fitting.

[0033] In this embodiment, in order to better complete the positioning, an elastic element 30 is provided inside the tube, and a positioning protrusion 31 is provided on the elastic element through the positioning hole.

[0034] In this embodiment, the tube is provided with axially oriented protrusions 29 evenly distributed along the circumferential direction so that it can fit more tightly with the tube fitting.

[0035] If the terms "first" and "second" are used in the above description to define the components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of distinguishing the components in the description. Unless otherwise stated, the above terms have no special meaning.

[0036] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0037] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0038] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0039] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
