Description

Technical Field

[0001] The utility model relates to the field of connecting columns, in particular to a connecting column convenient for assembly. Background Art

[0002] A connecting column, also known as a joint column, is a structural component widely used in many fields, used to connect different components or parts to improve the stability of the overall structure.

[0003] The existing connecting column is usually composed of a smooth fixing rod. The inside of the fixing rod is a hollow structure. A number of screw holes for installing and fitting fasteners such as screws are provided on the outer surface of the fixing rod. During use, a screw is directly driven into the fixing rod by using a tool such as a screwdriver for fixing and connecting. The smooth surface of the connecting column will significantly reduce the friction force with other connecting components (such as nuts, bolts, sockets, etc.). In mechanical connections, friction force is one of the key factors to maintain connection stability. The surface of the connecting column is smooth. When subjected to external loads or vibrations, the connecting components are prone to relative sliding, resulting in connection loosening or failure. The smooth surface of the connecting column and poor fit will also cause vibrations during the operation of mechanical components, resulting in unstable connection of the connecting components. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art solutions, the utility model provides a connecting column convenient for assembly, which can effectively solve the technical problem of unstable connection of the existing connecting column during connection.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a connecting column convenient for assembly, including a threaded head and a fixing rod. The threaded head and the fixing rod are integrally formed. A through groove extending along the axial direction of the fixing rod is arranged inside the fixing rod. A hollow rod is arranged inside the fixing rod. A number of engaging grooves extending along the axial direction of the hollow rod are arranged on the surface of the hollow rod.

[0006] Further, a number of threads are arranged on the inner wall of the threaded head, and the number of threads extends along the axial direction of the threaded head.

[0007] Further, a fixing ring is sleeved on the surface of the fixing rod, and a number of anti-slip lines are arranged on the surface of the fixing ring.

[0008] Further, the cross-sections of the threaded head and the fixing rod are both circular.

[0009] Further, the outer surface of the threaded head is a rough surface.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: For a connection column that is convenient for assembly in the present utility model, by providing multiple engaging grooves on the surface of the hollow rod, while increasing the connection points, the biting force between the connection column and other components is also enhanced, greatly improving the stability during connection, and enabling the connection column to be more conveniently assembled with other components.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Such as Figures 1 - 4As shown in the figure, a connecting column facilitating assembly includes a threaded head 2 and a fixing rod 1. The threaded head 2 and the fixing rod 1 are integrally formed. A through groove 6 extending along the axial direction of the fixing rod 1 is provided inside the fixing rod 1. A hollow rod 5 is provided inside the fixing rod 1. Multiple engaging grooves 7 extending along the axial direction of the hollow rod 5 are provided on the surface of the hollow rod 5. The multiple engaging grooves 7 on the surface of the hollow rod 5 enhance the biting force between the connecting column and other components while increasing the connection points, greatly improving the stability during connection and enabling the connecting column to be more conveniently assembled with other components. The inner wall of the threaded head 2 is provided with several threads 8, and the several threads 8 extend along the axial direction of the threaded head 2. A fixing ring 3 is sleeved on the surface of the fixing rod 1, and several anti-slip lines 4 are provided on the surface of the fixing ring 3, enhancing the gripping feeling and stability of the user or the assembly worker during the operation process, preventing sliding and falling off. The cross-sections of the threaded head 2 and the fixing rod 1 are both circular. The outer surface of the threaded head 2 is a rough surface. The smooth outer surface is not easy to accumulate dust and be contaminated with dirt, facilitating cleaning and maintenance and keeping the appearance of the connecting column clean and tidy.

[0019] When the connecting column facilitating assembly in this embodiment is in use, by providing the through groove 6 and the hollow rod 5, when the connecting column is assembled with other components, it can be assembled by directly engaging the engaging grooves 7 with other components. One end of the connecting column is connected by direct engagement, and the other end of the connecting column is connected with other components by screwing, with simple assembly and fast installation speed.

[0020] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
