[0002] A lamp is a general term for lighting tools, including chandeliers, table lamps, wall lamps, floor lamps, and more. It refers to an appliance that transmits, distributes, and modifies the light distribution of a light source. Besides the light source, it includes all components required to secure and protect the light source, as well as the wiring accessories necessary for connecting to the power supply. One such lamp on the market is a tube lamp, which can be freely adjusted at different angles to create different lighting effects.

[0003] However, the mounting structure of the lamp tube is usually relatively simple, and is often used in a hinged manner, which has limited rotation and angle adjustment, and brings certain difficulties to the desired lighting effect. Summary of the Invention

When the hinged outer plate is hingedly rotated with the hinged inner plate through the hinge shaft until the lamp tube is vertically downward, the outer wall of the second baffle is abutted against the inner wall of the first inner plate.

[0008] The present invention is further configured such that a wire hole is provided at the bottom of the hinged notch, and the wire hole is located between the two hinged outer plates, and the bolts connecting the mounting base plate and the abutting plate are hollow bolts.

When the abutting plate rotates one circle, the side wall of the second limiting portion abuts against the side wall of the first limiting portion.

[0010] The present invention is further configured such that a plurality of heat dissipation holes are provided on the top of the lamp tube.

[0011] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0012] 1. The multi-directional rotation structure provided by the present invention utilizes the abutment plate to realize rotation on the lower end surface of the mounting base plate, and at the same time utilizes the rotation of the hinged outer plate and the hinged inner plate to provide more multi-directional rotation options for the lamp tube than the traditional structure, and at the same time has a wider range of applications for different lighting effects.

[0026] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1 — Figure 6 :

[0027] A multi-directional rotation structure for a lamp, comprising a mounting base 1, a connecting portion 2 and a lamp tube 3, wherein a mounting through hole 10 is provided on the mounting base 1, and the lower hole edge of the mounting through hole 10 extends downward and is formed with a mounting protrusion 11, the connecting portion 2 comprises an abutment plate 20 abutting the upper end of the mounting protrusion 11, and the abutment plate 20 is provided with a rotating hole 21 connected to the mounting through hole 10, the mounting base 1 is connected to the mounting through hole 10 and the rotating hole 21 by bolts, and the abutment plate 20 is rotated on the lower surface of the mounting protrusion 11 by bolts, and two parallel hinged inner plates 22 are provided at the lower end of the abutment plate 20, and two parallel hinged outer plates 30 are provided at the upper end of the lamp tube 3, and the hinged inner plate 22 and the hinged outer plate 30 are hinged and rotated by a hinge shaft.

[0028] During the implementation process, the connecting part is connected to the bottom of the mounting base plate by bolts, and the connecting part is allowed to rotate on the mounting ridge, and then the hinged outer plate at the upper end of the lamp tube is hingedly connected to the hinged inner plate. While achieving overall rotation, the angle can also be adjusted using the hinged position, which brings a variety of lighting effects as a whole and greatly improves the scope of application.

[0029] Preferably, a hinged notch 31 is provided at the top of the lamp tube 3, and the hinged outer panel 30 is formed by extending upward from the bottom of the hinged notch 31. The top of the hinged notch 31 extends upward and is formed with a first baffle 32. A second baffle 23 is formed on one side of the two hinged inner panels 22. When the hinged outer panel 30 is hingedly rotated to the hinged inner panel 22 through the hinge shaft until the lamp tube 3 is vertically downward, the outer wall of the second baffle 23 is against the inner wall of the first baffle 32.

[0030] In the above structure, in order to prevent the hinge from rotating too much, the first baffle 32 and the second baffle 23 that can resist each other are used, which can not only keep the lamp tube in a vertical state, but also effectively protect the hinge from excessive twisting.

[0031] Preferably, a wire hole 33 is opened at the bottom of the hinge notch 31, and the wire hole 33 is located between the two hinged outer plates 30, and the bolt connecting the mounting base plate 1 and the abutting plate 20 is a hollow bolt.

[0032] In the above structure, the bolt is a hollow bolt, which can realize the threading of the wire. At the same time, a nut is provided at the end of the bolt to prevent the lamp from falling off when the lamp tube is rotated.

[0033] Preferably, a first limiting portion 12 is provided at the end of the mounting protrusion 11, and a second limiting portion 24 is provided at the end of the abutment plate 20. When the abutment plate 20 rotates one circle, the side wall of the second limiting portion 24 abuts against the side wall of the first limiting portion 12.

[0034] To prevent the wire from being excessively rotated when the lamp is rotated, thereby preventing a circuit breaker, the first and second limiting parts are designed to allow the wire to rotate a maximum of one full rotation to avoid the above-mentioned problem.

[0035] Preferably, a plurality of heat dissipation holes 34 are provided on the top of the lamp tube 3, which can provide a certain heat dissipation effect for the lamp tube.

[0036] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
