[0026] See Figures 1 to 3 As shown, a lamp fixture with a limiting and fastening lampshade includes a lamp body 2 and a lampshade 1, wherein the lampshade is a light-transmitting plastic lampshade or other conventional lampshade.

[0027] Furthermore, the lamp body includes a base 21, a hollow lamp post 22 fixed on the base, and a lamp holder 23 fixed at the top of the hollow lamp post. A light source board 24 is fixed on the top surface of the lamp holder. A power supply 11 and a control circuit board 12 connected to the light source board are provided inside the base. In this embodiment, the power supply is a rechargeable battery or a power plug, etc., and the control circuit board has a conventional structure in the prior art, mainly used to realize the switching control of the light source board. The wires of the control circuit board and the light source board are run through the hollow lamp post.

[0028] Furthermore, in this embodiment, the top edge of the lamp holder is integrally formed with several protrusions 3 on the same circular ring. These protrusions are located at the edge of the light source plate, and a snap-fit ​​groove 4 is provided on the side of the protrusion away from the light source plate. The height of the protrusions can be customized as needed, and the bottom edge of the snap-fit ​​groove is flush with the top edge of the lamp holder. Simultaneously, the inner wall of the mounting end of the lampshade is fixed with a mounting ring 6 by several support rods 5. The inner edge of the mounting ring is provided with a number of clearance grooves 7 matching the number of protrusions. The mounting ring can be a sheet-like metal structure or a sheet-like plastic structure, and the number of support rods can be two, three, four, or five. The support rods and mounting rings can be fixed by snaps, screws, or welding, while the support rods and lampshade can be fixed by screws, threads, or snaps.

[0029] In the assembling process, the mounting ring is arranged on the outer side of the protrusion, the protrusion passes through the avoiding slot to make the mounting ring in the same position as the buckle groove, and the mounting ring is rotated to be buckled into the buckle groove, and the supporting rod is limited on the end surface of the protrusion.

[0030] In the embodiment, the buckle groove is an inclined groove with a large opening at one end and a small opening at the other end, and the bottom wall of the buckle groove is flush with the top surface of the lamp holder. Therefore, in the mounting process, the mounting ring is closely attached to the top surface of the lamp holder, and the thickness of the mounting ring is greater than the width of the small opening of the buckle groove and less than the width of the large opening of the buckle groove. The mounting ring is rotated from the large opening of the buckle groove to the small opening of the buckle groove. Through the above structure, when the mounting ring is buckled, the small opening of the buckle groove can be limited by friction resistance, the mounting ring can be tightly limited, and the mounting ring can be prevented from falling off. The supporting rod is limited on the end surface of the protrusion to prevent excessive rotation, and the mounting position of the mounting ring is stable and reliable.

[0031] In the embodiment, the side surface of the base is provided with a charging interface 8 connected with the control circuit board, and the top surface of the base is provided with a switch button 9 connected with the control circuit board. The lampshade is a hollow cylindrical lampshade or a hollow circular truncated cone lampshade. The charging interface is a USB interface or a direct current DC interface, and the switch button can be a conventional press switch or a touch switch.

[0032] The utility model has the positive effect: the utility model discloses the structure is reasonable, and the protrusion on the top surface of the lamp holder is in the same ring, and the end surface of the protrusion has the buckle groove, and the inner wall of the mounting end of the lampshade is connected with the mounting ring through the supporting rod, and the inner edge of the mounting ring has the avoiding slot, and when the lampshade and the lamp holder are combined, the protrusion is inserted from the avoiding slot and rotated to make the inner edge of the mounting ring buckled into the buckle groove, and when buckling, the supporting rod is limited on the end surface of the protrusion, the convenience of dismounting is improved, and the utility model is not easy to loosen or damage, and the reliability of the connection of the two can be guaranteed.

[0033] And the buckle groove is an inclined groove with a large opening at one end and a small opening at the other end, and the mounting ring is buckled into the buckle groove from the large opening end and is limited by the friction resistance of the small opening of the inclined groove to prevent loosening or falling off, and the accuracy and reliability of the mounting position are guaranteed.

[0034] Embodiment 2

When the mounting ring is rotated, it can be limited by the stop block to prevent excessive rotation, ensure the accuracy of the installation position, and when limited, it can be limited by the friction resistance of the inner wall of the buckle groove to prevent falling. Moreover, the stop block can also be provided at the small opening end of the buckle groove, so that the installation position of the mounting ring can be limited by the stop block, and the double limiting can be realized by cooperating with the support rod abutting against the end surface of the protrusion. In this embodiment, the support rod can also not abut against the end surface of the protrusion, but can be limited by the stop block, so as to ensure the effectiveness of the limiting and improve the installation reliability.

[0036] The standard parts used in the embodiment can be directly purchased from the market, and the non-standard structural parts according to the description in the specification can also be directly processed without doubt according to the existing technical knowledge, and the connection mode of each part adopts the mature conventional means in the existing technology, and the machinery, parts and equipment adopt the conventional models in the existing technology, so the specific description is not made here.
