Description

Technical Field

[0001] This utility model relates to the field of lampshade technology, and in particular to a PC lampshade that is easy to change colors. Background Technology

[0002] PC lampshades are lamp covers made of polycarbonate material, commonly used in household lamps, commercial lighting, and other scenarios. They are resistant to high and low temperatures, adaptable to different environments, and can be customized in color. They are available in transparent, frosted, and other styles to match different decoration styles.

[0003] When changing the color of existing PC lampshades, most lampshades are designed to fit the structure of the lamp fixture, using clips, screws, or rotating snap-fit ​​designs. The clips are often hidden in the edge gaps, requiring precise location of the force point to pry them open. Improper force can easily cause breakage, leading to troublesome disassembly and reassembly. In addition, since PC material itself is not suitable for color change through simple dyeing or painting, the entire lampshade needs to be replaced. Although the unit price of a new lampshade is not high, the costs of transportation and labor, coupled with frequent replacements over a long period, will accumulate. Moreover, most old lampshades are simply discarded. Although PC material is recyclable, ordinary users find it difficult to sort and recycle it, resulting in resource waste and environmental pressure. Utility Model Content

[0004] The purpose of this invention is to provide a PC lampshade that allows for easy color changes, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A PC lampshade that facilitates color changes includes a lampshade, with first baffles fixedly installed on both sides inside the lampshade. A deformation guide groove is provided on the top inside the lampshade. A colored sheet is movably connected between the lampshade and the two first baffles. A limiting protrusion is movably connected inside the colored sheet, and the limiting protrusion is located near one end of the colored sheet.

[0007] As a further preferred embodiment of this utility model, both sides of the lampshade are fixedly connected with bent portions. The bent portions on both sides of the lampshade allow the lampshade to be quickly inserted or snapped into the mounting groove inside the lamp fixture.

[0008] As a further preferred embodiment of this utility model, the lampshades located on both sides of the deformation guide groove are provided with limiting grooves. The limiting grooves can work with the limiting protrusions to limit the color film between the lampshade and the two first baffles, thereby realizing the positioning and installation of the color film.

[0009] As a further preferred embodiment of this utility model, two second baffles are fixedly installed on the side of the top of the lampshade away from the limiting groove, and the two second baffles are respectively located on one side of the deformation guide groove. One end of each of the two second baffles is fixedly connected to the corresponding first baffle, so that after the colored film is inserted between the lampshade and the two first baffles, one end of the colored film is inserted into the two second baffles to limit the pushing process of the colored film.

[0010] As a further preferred embodiment of this utility model, spokes are fixedly installed on the slopes on both sides of the lampshade. When the lampshade is disassembled and assembled by snap-fit, the two spokes can provide an operating position for the hand, thereby cooperating with the deformation guide groove so that the lampshade can bend around the deformation guide groove as the midpoint, so that the bent parts on both sides of the lampshade can be disengaged from the mounting groove on the inner side of the lamp housing.

[0011] As a further preferred embodiment of this utility model, the colored film has a perforated groove. When the colored film is inserted into the lampshade, the top of the colored film fits into the top of the lampshade, and the perforated groove and the two limiting grooves are in the same vertical line position.

[0012] As a further preferred embodiment of this utility model, connecting pieces are fixedly connected to both sides of the limiting groove and both sides of the punch groove, and the upper surface of the limiting protrusion protrudes above the colored film. A pull piece is fixedly connected to the bottom of the limiting protrusion. When the colored film is inserted into the lampshade, the top of the limiting protrusion will be engaged in the two limiting grooves, thereby cooperating with the two first baffles and the second baffle to achieve quick positioning and installation of the colored film.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this utility model, the color film can be quickly replaced through two sets of first and second baffles inside the lampshade, thereby changing the light transmission color at a lower cost without replacing the lampshade. At the same time, a deformation guide groove is set at the top of the lampshade, and together with two spokes on the outside of the lampshade, the lampshade can be quickly disassembled and assembled, reducing the difficulty of replacing the color film.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-6 As shown, the present invention provides a PC lampshade that is easy to change colors, including a lampshade 1, with first baffles 2 fixedly installed on both sides inside the lampshade 1, and a deformation guide groove 3 opened on the top inside the lampshade 1. A colored sheet 4 is movably connected between the lampshade 1 and the two first baffles 2, and a limiting protrusion 5 is movably connected inside the colored sheet 4, with the limiting protrusion 5 close to one end of the colored sheet 4.

[0024] like Figures 1-3 As shown, both sides of the lampshade 1 are fixedly connected with bent portions. The bent portions on both sides of the lampshade 1 allow the lampshade 1 to be quickly inserted or snapped into the mounting slot inside the lamp fixture. The lampshade 1 located on both sides of the deformation guide groove 3 has a limiting groove 6. The limiting groove 6 can cooperate with the limiting protrusion 5 to limit the colored sheet 4 between the lampshade 1 and the two first baffles 2, realizing the positioning and installation of the colored sheet 4. Two second baffles 7 are fixedly installed on the top side of the lampshade 1 away from the limiting groove 6, and the two second baffles 7 are respectively located on one side of the deformation guide groove 3. One end of each of the two second baffles 7 is respectively The color sheet 4 is fixedly connected to the corresponding first baffle 2, so that after the color sheet 4 is inserted between the lampshade 1 and the two first baffles 2, one end of the color sheet 4 is inserted into the two second baffles 7 to limit the pushing process of the color sheet 4. Spokes 8 are fixedly installed on the slopes on both sides of the lampshade 1. When the lampshade 1 is disassembled and assembled by snap-fit, the two spokes 8 can provide an operating position for the hand, so that the lampshade 1 can be deformed and bent with the deformation guide groove 3 as the midpoint, so that the bent parts on both sides of the lampshade 1 can be disengaged from the mounting groove inside the lamp housing.

[0025] like Figures 2-5As shown, the colored sheet 4 has a perforated groove 9. When the colored sheet 4 is inserted into the lampshade 1, the top of the colored sheet 4 fits against the top of the lampshade 1. The perforated groove 9 and the two limiting grooves 6 are on the same vertical line. Connecting pieces 10 are fixedly connected to both sides of the limiting groove 6 and both sides of the perforated groove 9. The upper surface of the limiting protrusion 5 protrudes above the colored sheet 4. The bottom of the limiting protrusion 5 is fixedly connected to a pull piece 11. When the colored sheet 4 is inserted into the lampshade 1, the top of the limiting protrusion 5 will be inserted into the two limiting grooves 6, thereby cooperating with the two first baffles 2 and the second baffles 7 to achieve quick positioning and installation of the colored sheet 4.

[0026] It should be noted that this utility model is a PC lampshade that facilitates color replacement. When replacing the color film 4, the outer spokes 8 can be held by hand, and the lampshade 1 can be bent with the deformation guide groove 3 at the top as the weakest point. As a result, the bent parts on both sides of the lampshade 1 will disengage from the mounting groove of the lamp housing. Then, the pull tab 11 is pulled down, which will cause the pull tab 11 to move the limiting protrusion 5 down in the punch groove 9, and deform the connecting pieces 10 on both sides of the limiting protrusion 5, thereby causing the top of the limiting protrusion 5 to disengage from the two limiting grooves 6. Then, the colored sheet 4 can be pulled out from between the lampshade 1 and the two first baffles 2. Then, the new colored sheet 4 is inserted between the first baffles 2 inside the lampshade 1. When pushed to the end, one end will be stuck in the second baffle 7, restricting the position. At this time, the punch 9 on the colored sheet 4 will be aligned with the limiting groove 6 of the lampshade 1. The limiting protrusion 5 in the punch 9 will pop into the limiting groove 6, fixing the colored sheet. Finally, the lampshade 1 is kneaded and deformed in the same way as above, so that the bent parts on both sides of the lampshade 1 are respectively inserted into the mounting groove of the lamp housing.
