[0002] Lenses are widely used in home environments for lighting, lighting, landscaping and other purposes. They can also be used to adjust the color, brightness, and illumination direction of the light source in industrial scenarios. In common home lighting equipment, the lens is generally designed to be suitable for the outline of the ceiling lamp. The shape is a plate structure and is installed at the bottom of the ceiling lamp or grille lamp to diffuse light and adjust the color temperature.

[0003] China Patent Publication No. CN217899765U, published on November 25, 2022, discloses a lens that can be easily replaced. This technical solution has a separate mounting plate and lens assembly, and the lens assembly can be easily inserted or removed from the mounting plate. However, it still has some shortcomings:

[0004] After installation, the lens is only fixed by fitting the edge of the mounting hole and the outer wall of the lens's mounting column. The installation may be slightly insufficiently secure. Although it will not accidentally fall out during normal lifting, it is easy to fall out due to vibration during transportation, material distribution, manual handling or lens installation, which can easily cause damage and scratches to the lens.

[0005] Moreover, when the lens needs to be removed, the mounting post needs to be pressed out of the mounting hole by fingers or a slender tool. This may cause scratches and fingerprints on the mounting post at the top of the lens, which may affect the lighting effect. Therefore, further improvement is needed. Utility Model Content

[0006] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a technical solution that can make the lens more secure during installation, avoid accidental dislocation during transportation, etc., and avoid removing the lens without touching the lens itself.

[0007] In order to achieve the above object, the present invention provides the following solutions:

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 5 The illustrated embodiment of the present invention preferably provides a lens assembly for convenient lens replacement, comprising a mounting plate 1 having a rectangular profile and a plurality of lens sheets 12 mounted on the mounting plate 1. The mounting plate 1 is provided with a plurality of mounting holes 2. The lens sheets 12 are provided with connecting posts 3 that can be inserted into the mounting holes 2. A soft plastic member 4 is disposed within the mounting plate 1 to reinforce the securing of the connecting posts 3 or facilitate their removal. The mounting plate 1 is also provided with a plurality of mounting assemblies 5 for securing the soft plastic members 4. The mounting plate is connected to the device via snaps or screws. When the lens sheets are mounted on the mounting plate, the connecting posts are inserted into the mounting holes. Once inserted into the holes, the connecting posts are clamped by the soft plastic member, enhancing the stability of the lens assembly and preventing them from being dislodged due to vibration during transportation, material distribution, manual handling, or lens installation. To remove the lens sheets, the connecting posts can be squeezed by pinching the two sides of the soft plastic member, forcing the connecting posts outward from within the soft plastic member, allowing the lens sheets to be removed without contacting the connecting posts or the lens sheets themselves. The mounting assembly secures the soft plastic component to the mounting plate. To prevent the soft plastic component's placement from affecting the lighting effect, a relatively transparent material is used. The easy installation and removal of the lens allows for convenient replacement of lenses of varying shapes, effects, and models.

[0025] The mounting holes 2 of the present invention are evenly spaced on the mounting plate 1. The location of the mounting holes affects the lens pieces, and the mounting holes are evenly and equally spaced so that the lens pieces can be densely arranged.

[0026] The outer edge of the soft plastic part 4 of the present invention is oval. The oval outer edge of the soft plastic part allows the soft plastic part to be fixed with the longer two sides, and the shorter two sides are used for people to pinch together, so that the soft plastic part can be pulled out of the connecting column when pinched together.

[0027] The soft plastic member 4 in this utility model includes a through-hole 41 extending through its upper and lower ends. The top of the soft plastic member 4 features a curved surface 42 that converges toward the inside of the through-hole 41. Positioning support holes 43 are located at the bottom of the longer sides of the soft plastic member 4. These two longer sides of the soft plastic member 4 are connected to extensions 44 that can be fixed to the mounting plate 1. The through-holes are designed to fit over the connecting column, further securing it and increasing the stability of the lens after installation. The curved surface makes the soft plastic member more comfortable to grasp and provides a light-dispersing effect. The positioning support holes and extensions are used to connect to the mounting plate via a mounting assembly.

[0028] The connecting column 3 described in the present invention is inserted into the mounting hole 2, and a protruding portion 31 is left. The protruding portion 31 is inserted into the through-hole 41, and the protruding portion 31 is separated from the through-hole 41 by pinching the soft rubber part 4. Existing lens sheets all have connecting columns for installation and connection with the mounting plate. The length of the connecting column is set to a longer non-standard version, which allows the connecting column to be inserted deeper into the through-hole and the connection to be tighter, but it cannot be higher than the maximum height of the soft rubber part. The protruding portion is the part of the connecting column that is exposed from the mounting hole after the insertion of the connecting column. After the exposed part is inserted into the through-hole, it will be clamped and fixed by the soft rubber part. When removing it, by pinching and squeezing the two ends of the soft rubber part, the top of the connecting column in the through-hole receives the pushing force from both sides. During this process, due to the deformation of the soft rubber part, the lower part of the through-hole of the soft rubber part will open appropriately, so that the connecting column is gradually separated from the mounting hole and removed.

[0029] The extension portion 44 described in the present invention can be fixed to the mounting plate 1 by screwing. The extension portion can be provided with a hole, and the mounting plate can also be provided with screw holes on both sides of the mounting hole, and then the bolts can be passed through the hole and screwed into the screw holes to achieve the installation and fixation of the extension portion.

[0030] The inner diameter of the through hole 41 in the present invention is smaller than the inner diameter of the mounting hole 2. The purpose of such a setting is to make the clamping force of the soft glue through hole on the connecting column stronger and make the installed lens piece more stable.

[0031] The mounting assembly 5 of the present invention includes a plurality of positioning recesses 51 corresponding to each mounting hole 2 and provided on the top wall of the mounting plate 1. The shape of the positioning recesses 51 matches the outer edge of the soft plastic component 4 and accommodates the installation of the soft plastic component 4. Positioning posts 52 are provided on the longer sides of the positioning recesses 51, which are inserted into the positioning support holes 43. The positioning recesses are also elliptical in shape, and are used to accommodate the soft plastic component, so that the through-holes of the soft plastic component and the mounting holes are concentric. The positioning posts on both sides of the interior insert into the positioning support holes of the soft plastic component to ensure stable installation of the soft plastic component, preventing displacement during lens connection.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
