Detailed Description

The present application is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments or technical features described below may form a new embodiment.

In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate orientations and positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1, the application provides a detachable lamp shade, including diffuser plate 1, framework 2, the inside wall of framework 2 forms a cavity, diffuser plate 1 sets up in the cavity, the inside extension of the lower extreme of framework 2 forms first boss 21, first boss 21 forms continuous loop configuration, first boss is suitable for supporting diffuser plate 1, still be provided with second boss 22 and a plurality of stopper 3 on the inside wall of framework 2, the one end and the second boss 22 butt of stopper 3, the other end and the first boss 21 of stopper 3 define a space, diffuser plate 1 can insert in the space, and then the lower surface and the first boss 21 butt of diffuser plate 1, the upper surface and the one end butt of stopper 3 of diffuser plate 1, diffuser plate 1 tightly fixes on framework 2 through the top of stopper 3. Preferably, the stopper 3 is made of an elastic material, a space defined by the stopper 3 and the first boss 21 is smaller than the thickness of the diffusion plate 1, and after the diffusion plate 1 is inserted into the space, the diffusion plate 1 will press the stopper 3 to deform the stopper 3 to generate a downward acting force, so that the diffusion plate 1 is fixed on the first boss 21 by the acting force. During installation, the diffusion plate 1 is inserted between the first boss 21 and the limiting block 3 only before the detachable lampshade is installed on the lamp panel, and the diffusion plate 1 can be installed; when the lamp panel is detached, the detachable lampshade is detached from the lamp panel, the limiting block 3 is detached from the frame body, and the diffusion plate 1 can be detached from the cavity and replaced.

Stopper 3 includes main part 31, the both ends of main part 31 extend to same side and form butt portion 32 and fixed part 33 respectively, preferably, stopper 3 is integrated into one piece, that is, stopper 3 is by a monoblock elastic material stamping forming, butt portion 32's width is less than first boss 21, fixed part 33's width is less than second boss 22, butt portion 32 and fixed part 33's width is less than first boss 21 and second boss 22 and can avoid butt portion 32 and fixed 33 unnecessary part to extend to outside first boss 21 and the second boss 22, influence the illuminating effect.

In some embodiments, the inner side wall of the frame body 1 is further provided with a plurality of limiting grooves 23, the width of the limiting grooves 23 is consistent with the width of the main body 31 of the limiting block 3, and the main body 31 of the limiting block 3 can be embedded into the limiting grooves 23 to limit the sliding of the limiting block 3 in the horizontal direction, so as to prevent the diffusion plate 1 from being loosened due to the horizontal sliding of the limiting block 3 in the frame body. Preferably, the limiting groove 23 and the limiting block 3 are symmetrically arranged on the inner side wall of the frame body 2, so that the diffusion plate 1 can be uniformly stressed.

In other embodiments, as shown in fig. 6, only the lower ends of the two opposite sides of the frame body 2 extend inward to form the first bosses 21. Similarly, the second boss 22 and the limiting groove 23 are only disposed on the inner side walls of the two sides where the first boss 21 is disposed, the main body portion 31 of the limiting block 3 is embedded in the limiting groove 23, and the fixing portion 33 of the limiting block 3 is connected with the second boss 22 by a fixing method such as adhesion, so that the limiting block 3 does not fall off from the limiting groove 23. When the mounting structure is used, a user only needs to insert one end of the diffusion plate 1 into a space defined by the limiting block 3 and the first boss 21 after penetrating through the first boss 21 on one side, the diffusion plate 1 is abutted to the limiting block 3, and the limiting block 3 is compressed; the other end of the diffusion plate 1 penetrates through the first boss 22 on the other side and is inserted into a space between the limiting block 3 and the first boss 21; then loosen diffuser plate 1, stopper 3 deformation produces the effort and tightly pushes up diffuser plate 1 on first boss 21, realizes the fixed to diffuser plate 1.

When this kind of embodiment installation was dismantled, the lamp shade was dismantled from the lamp panel when need not to dismantle, only needed to upwards press one side of diffuser plate 1, with the opposite side roll-off in first boss 21 of diffuser plate 1, can take off diffuser plate 1, dismantles the maintenance degree of difficulty and hangs down, the quick overhaul of being convenient for.

Preferably, the limiting block 3 is made of aluminum alloy material which is low in density and not prone to rusting and corrosion. The metal limiting block 3 is firmer and more durable, the installation mode is simple, the construction time is shortened, and particularly, the construction efficiency can be greatly improved during a large number of operation constructions.

In some embodiments, the width of the first boss 21 is 3mm to 5mm, the width of the first boss 21 is affected by the overall size of the lampshade, when the overall size of the lampshade is larger, the size of the diffuser plate 1 is larger, the weight of the diffuser plate 1 is also larger, and therefore the first boss 21 needs a larger width to support the diffuser plate 1; when the entire size of the lamp housing is small, the size of the diffusion plate 3 is small, the weight of the diffusion plate 1 is light, and the first boss 21 needs only a small width to support the diffusion plate 3.

The application still provides a lamps and lanterns, including above-mentioned detachable lamp shade, luminescence unit and lamp panel, luminescence unit sets up on the lamp panel, and detachable lamp shade passes through connected modes such as buckle with the lamp panel and can dismantle the connection.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed. The scope of protection claimed by this application is defined by the following claims and their equivalents.
