Description

Technical Field

[0001] This utility model relates to the field of lampshade technology, and in particular to a snap-on replacement structure for a lampshade. Background Technology

[0002] Reference Figure 7 As shown, the existing lampshade structure uses a snap-fit ​​mechanism to achieve quick assembly and disassembly of the lampshade and lamp body. While convenient and efficient, this method presents significant assembly risks. Since the snap-fit ​​components are mostly made of plastic, their toughness is limited. Improper force, angular deviations, or hasty handling during assembly can easily lead to breakage. Once a snap-fit ​​breaks, the lampshade must be scrapped, resulting in high production costs. Utility Model Content

[0003] To reduce the possibility of scrapping due to snap breakage during assembly, this application provides a snap replacement structure for a lampshade.

[0004] The snap-fit ​​replacement structure for a lampshade provided in this application adopts the following technical solution: A snap-fit ​​replacement structure for a lampshade includes a lampshade body and a snap-fit ​​replacement component. The snap-fit ​​replacement component includes a snap-fit ​​ring, a plug-in portion, and a limiting portion. The plug-in portion and the limiting portion are both fixedly connected to the snap-fit ​​ring. The limiting portion has a limiting groove. The lampshade body has a plug-in groove that can be plugged into the plug-in portion. The inner surface of the lampshade body has a limiting block that can be mated with the limiting groove. When the snap-fit ​​replacement component is installed on the lampshade body, the plug-in portion is plugged into the plug-in groove, and the limiting groove is mated with the limiting block.

[0005] By adopting the above technical solution, the retaining ring replacement part is connected to the lamp cover body's insertion groove and limiting block through the retaining ring, insertion part and limiting part, so as to achieve a detachable connection. As an independent component, the retaining ring replacement part can replace the damaged part separately, avoiding the need to replace the entire lamp cover, reducing maintenance costs. The retaining ring fits tightly with the lamp cover body, and the cooperation between the limiting block and the limiting groove prevents the retaining ring from loosening or falling off during use, ensuring connection reliability and reducing the possibility of buckle breakage and scrapping during assembly.

[0006] Preferably, it also includes a reinforcing rib, the two ends of which are fixedly connected to the snap ring and the plug-in part, respectively.

[0007] By adopting the above technical solution, the stress at the connection between the plug and the snap ring is dispersed by the reinforcing ribs, avoiding breakage caused by frequent plugging and unplugging or long-term stress. The reinforcing ribs can reduce the elastic deformation of the plug during installation, ensuring the accuracy and stability of the plug fit.

[0008] Preferably, the limiting block is arranged in a gradually expanding shape from the side near the locking ring to the side away from the locking ring.

[0009] By adopting the above technical solution, the gradually expanding shape forms a guide slope, making it easier for the limiting block to slide into the limiting groove, reducing the alignment difficulty during installation, reducing operation time, and the gradually expanding structure restricts the limiting block from falling out in the opposite direction, ensuring a firm connection after installation and avoiding detachment due to accidental contact.

[0010] Preferably, the side of the limiting part away from the limiting groove is movably positioned.

[0011] By adopting the above technical solution, the movable end allows the limiting part to undergo elastic deformation during installation, which facilitates the sliding of the limiting block into the limiting groove. At the same time, it provides pre-tightening force to maintain the connection. By deforming the movable end with external force, the limiting can be easily released, which facilitates quick separation of the retaining ring and the lamp cover during maintenance.

[0012] Preferably, the end of the limiting part away from the snap ring is provided with a force-applying part. When the limiting groove and the limiting block cooperate, the distance between the end of the force-applying part near the snap ring and the end away from the snap ring and the inner wall of the lampshade body gradually increases.

[0013] By adopting the above technical solution, the wedge-shaped structure of the force-applying part provides a lever effect. Users can press the force-applying part with tools or fingers to achieve elastic deformation of the limiting part with less force, reducing the difficulty of disassembly and reducing the possibility of damaging the lamp cover body due to violent disassembly.

[0014] Preferably, the snap ring has a reinforcing part on the side near the insertion part, and the reinforcing part is gradually widened from the side near the snap ring to the side away from the snap ring. When the snap ring is installed on the lampshade body, the end of the reinforcing part away from the snap ring abuts against the lampshade body.

[0015] By adopting the above technical solution, the gradually expanding reinforcing part increases the contact area between the snap ring and the lamp cover body, disperses radial pressure, improves the resistance to deformation, and reduces the possibility of the snap ring deforming and bending during installation.

[0016] Preferably, the end of the plug-in portion away from the snap ring is provided with a guide portion, and the guide portion is gradually tapered from the side near the plug-in portion to the side away from the plug-in portion.

[0017] By adopting the above technical solution, a tapered guide head is formed by a tapered shape, which guides the plug part to be smoothly inserted into the plug slot, reducing alignment time and improving installation efficiency.

[0018] The main technical effects of this utility model are reflected in the following aspects: 1. The snap ring replacement part of this utility model cooperates with the insertion groove and limiting block of the lamp cover body through snap ring, insertion part and limiting part to achieve detachable connection. As an independent component, the snap ring replacement part can replace the damaged part separately, avoiding the need to replace the entire lamp cover, reducing maintenance costs. The snap ring fits tightly with the lamp cover body, and the cooperation between the limiting block and the limiting groove prevents the snap ring from loosening or falling off during use, ensuring connection reliability and reducing the possibility of buckle breakage and scrapping during assembly. 2. The movable end of this utility model allows the limiting part to undergo elastic deformation during installation, which facilitates the sliding of the limiting block into the limiting groove. At the same time, it provides pre-tightening force to maintain the connection. By deforming the movable end by external force, the limiting can be easily released, which facilitates quick separation of the retaining ring and the lamp cover during maintenance. 3. The gradually expanding reinforcing part of this utility model increases the contact area between the snap ring and the lamp cover body, disperses radial pressure, improves the resistance to deformation, and reduces the possibility of the snap ring deforming and bending during installation.

[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0028] This application discloses a snap-on replacement structure for a lampshade.

[0029] Reference Figure 1 and Figure 3 This embodiment of a lampshade snap-fit ​​replacement structure includes a lampshade body 1 and a snap-ring replacement component 2. The snap-ring replacement component 2 includes a snap-fit ​​ring 3, a plug-in part 4, and a limiting part 5. The plug-in part 4 and the limiting part 5 are both fixedly connected to the snap-fit ​​ring 3. The limiting part 5 is provided with a limiting groove 6. The lampshade body 1 is provided with a plug-in groove 7 that can be plugged into and cooperate with the plug-in part 4. The inner surface of the lampshade body 1 is provided with a limiting block 8 that can cooperate with the limiting groove 6. When the snap-ring replacement component 2 is installed on the lampshade body 1, the plug-in part 4 is plugged into and cooperates with the plug-in groove 7, and the limiting groove 6 cooperates with the limiting block 8.

[0030] Reference Figure 2 The retaining ring replacement part 2 is connected to the lamp cover body 1 through the retaining ring 3, the insertion part 4 and the limiting part 5, and the insertion groove 7 and the limiting block 8 to achieve a detachable connection. As an independent component, the retaining ring replacement part 2 can replace the damaged parts separately, avoiding the need to replace the entire lamp cover and reducing maintenance costs. The retaining ring 3 fits tightly with the lamp cover body 1, and the cooperation between the limiting block 8 and the limiting groove 6 prevents the retaining ring from loosening or falling off during use, ensuring connection reliability and reducing the possibility of the buckle breaking and causing scrap during assembly.

[0031] Reference Figure 5 It also includes a reinforcing rib 9, with its two ends fixedly connected to the snap ring 3 and the insertion part 4, respectively. The reinforcing rib 9 disperses the stress at the connection between the insertion part 4 and the snap ring 3, preventing breakage due to frequent insertion and removal or long-term stress. The reinforcing rib 9 can also reduce the elastic deformation of the insertion part 4 during installation, ensuring the accuracy and stability of the insertion fit.

[0032] Referring to Figure 4, the limiting block 8 is gradually widened from the side near the snap ring 3 to the side away from the snap ring 3. The widened shape forms a guide slope, making it easier for the limiting block 8 to slide into the limiting groove 6, reducing the difficulty of alignment during installation and reducing operation time. In addition, the widened structure restricts the limiting block 8 from falling out in the opposite direction, ensuring a firm connection after installation and preventing it from falling off due to accidental contact.

[0033] Reference Figure 3 The side of the limiting part 5 away from the limiting groove 6 is movably positioned. The movable end allows the limiting part 5 to undergo elastic deformation during installation, which facilitates the sliding of the limiting block 8 into the limiting groove 6. At the same time, it provides a preload to maintain the connection. By deforming the movable end with external force, the limiting can be easily released, which facilitates quick separation of the retaining ring and the lamp cover during maintenance.

[0034] Reference Figure 6A force-applying part 10 is fixedly connected to the end of the limiting part 5 away from the snap ring 3, i.e., the movable end. When the limiting groove 6 and the limiting block 8 are engaged, the distance between the end of the force-applying part 10 near the snap ring 3 and the end away from the snap ring 3 and the inner wall of the lampshade body 1 gradually increases. The wedge-shaped structure of the force-applying part 10 provides a lever effect. Users can press the force-applying part 10 with tools or fingers to achieve elastic deformation of the limiting part 5 with a small force, reducing the difficulty of disassembly and reducing the possibility of damaging the lampshade body 1 due to violent disassembly.

[0035] Reference Figure 5 The snap-fit ​​ring 3 has a reinforcing part 11 on the side near the insertion part 4. The reinforcing part 11 is gradually widened from the side near the snap-fit ​​ring 3 to the side away from the snap-fit ​​ring 3. When the snap-fit ​​ring 3 is installed on the lamp cover body 1, the reinforcing part 11 allows one end of the snap-fit ​​ring 3 to abut against the lamp cover body 1. The gradually widening reinforcing part 11 increases the contact area between the snap-fit ​​ring 3 and the lamp cover body 1, disperses radial pressure, improves the resistance to deformation, and reduces the possibility of the snap-fit ​​ring 3 deforming and bending during installation.

[0036] Reference Figure 5 The end of the connector 4 away from the locking ring 3 is provided with a guide portion 12, which is tapered from the side near the connector 4 to the side away from the connector 4. The tapered shape forms a conical guide head, which guides the connector 4 to be smoothly inserted into the connector slot 7, reducing alignment time and improving installation efficiency.

[0037] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
