[0002] A lamp is a common lighting and decorative structure, which generally includes a lamp body, a light source board and a lampshade. Most of the existing lampshades adopt a single - layer structure, and the lampshade is mostly connected to the lamp body by threads or can also be connected to the lamp body by a snap - fit method. Although it can meet the usage requirements in general cases, its single - lampshade structure is not conducive to the softness of the irradiated light and the uniformity of the irradiated light, and it is easy to have a dazzling situation, affecting the lighting effect. On this basis, a lamp structure with a double - layer lampshade has emerged in the market. However, the disassembly and assembly operations of conventional double - layer lampshade lamps are relatively inconvenient, which will reduce the disassembly and assembly efficiency, and at the same time, it will also affect the assembly stability, and the applicability and practicability are limited.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the 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 utility model.

[0026] Example 1

[0027] As shown Figures 1 to 3 in the figure, a snap - type double - layer lampshade structure is connected to the lamp base 1, including an inner lampshade 2 and an outer lampshade 3; in this embodiment, both the inner lampshade and the outer lampshade are made of conventional materials of the prior art, mainly for light transmission and illumination.

[0028] In the actual application process, a convex ring 4 is integrally formed at the top of the inner wall of the inner lampshade, and a buckling convex edge 5 is integrally formed at the top edge of the outer wall of the convex ring; during assembly, the convex ring is snapped into the inner cavity of the lamp base, and the buckling convex edge abuts against the inner wall of the inner cavity of the lamp base for positioning. It is mainly achieved by utilizing the certain deformation performance of the lampshade. The friction force at the connection with the lamp base can be increased through the buckling convex edge, thus ensuring the stability and reliability of the installation;

[0029] In the actual application process, a snap - convex edge 6 inclined towards the center is integrally formed at the top edge of the outer lampshade; during assembly, the inner lampshade is inside the outer lampshade, and the snap - convex edge of the outer lampshade is positioned on the outer wall of the convex ring for limiting; the convex ring of the inner lampshade abuts against the inner wall of the lamp base for positioning. In order to improve the connection effectiveness and reliability between the outer lampshade and the inner lampshade, the diameter of the top - surface opening of the outer lampshade is larger than the diameter of the top edge of the inner lampshade, and the diameter of the opening of the snap - convex edge matches the outer diameter of the convex ring. Through the above structure, during assembly, one end of the inner lampshade can be first inserted into the outer lampshade, and then under the action of an external force, the other end of the inner lampshade is slightly deformed and snapped into the outer lampshade to achieve snap - positioning of the two, which can ensure the stability of the assembly and is conducive to preventing loosening or falling off.

[0030] In the actual application process, the bottom surface of the bottom wall of the inner lampshade is attached to the top surface of the bottom wall of the outer lampshade. In this embodiment, the inner lampshade is circular; the shape of the outer lampshade matches the shape of the inner lampshade. An L - shaped screw - buckle groove 7 is provided on the outer wall of the convex ring. Through the circular shape and the L - shaped screw - buckle groove, a clamping point can be processed on the inner wall of the lamp base, and the snap - connection is achieved through the cooperation of the clamping point and the L - shaped screw - buckle groove, and the positioning is achieved by cooperating with the pressing action of the buckling convex edge, improving the convenience and effectiveness of the installation. In the actual application process, the horizontal angle of the inclination of the snap - convex edge towards the center is 30° - 45°. This angle is beneficial for the inner lampshade to be snapped into the outer lampshade.

[0031] The utility model has positive effects: The structure of the utility model is reasonably arranged. It is provided with an inner lamp shade and an outer lamp shade, and the top of the outer lamp shade has a buckle convex edge inclined towards the center. Thus, the outer lamp shade can be buckled on the outside of the inner lamp shade, and at the same time, the inner lamp shade can be buckled on the lamp base, improving the convenience of disassembly and assembly, facilitating inspection and maintenance operations, and also being beneficial to improving the lighting decoration effect, enhancing the assembly stability and effectiveness, with strong applicability and good practicability.

[0033] See Figures 4 to 5 As shown, this embodiment is basically the same as Embodiment 1, with the difference being that: the inner lamp shade is rectangular or oval; the shape of the outer lamp shade matches the shape of the inner lamp shade.

[0034] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification, they can also be directly processed without any doubt according to the existing common technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts, and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0035] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or variations derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
