[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an easily expandable plastic frame, comprising:
[0031] Multiple main plastic frame panels 1 are provided with an extension mechanism. It should be noted that when the plastic frame needs to be extended, the size of the arc-shaped storage groove 5 extended by the plastic extension plate 4 can be adjusted as needed to facilitate the extension.
[0032] The extension mechanism includes a rotating shaft 3, a plastic extension plate 4, an intermediate shaft 6, a main gear 7, an auxiliary gear 8, a sleeve 9, and a connecting rod 10;
[0033] The rotating shaft 3 is rotatably mounted on multiple main plastic frame plates 1, the plastic extension plate 4 is fixedly mounted on the rotating shaft 3, the intermediate shaft 6 is rotatably mounted on the bottom of the main plastic frame plate 1 located in the middle position, the main gear 7 is fixedly sleeved on the outside of the intermediate shaft 6, the auxiliary gear 8 is fixedly sleeved on the outside of the rotating shaft 3, the main gear 7 and the auxiliary gear 8 mesh with each other. It should be noted that when the main gear 7 rotates, multiple auxiliary gears 8 can rotate synchronously.
[0034] The bottom of the sleeve 9 is fixedly connected to the abutment rod 10, and the abutment rod 10 is snapped into a plastic extension plate 4.
[0035] With the aforementioned expansion mechanism, when the plastic frame needs to be expanded, the intermediate shaft 6 is rotated, the main gear 7 drives the auxiliary gear 8 to rotate, the auxiliary gear 8 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives multiple plastic expansion plates 4 to rotate. The size of the plastic expansion plates 4 moving out of the arc-shaped storage groove 5 is adjusted according to actual needs, and then the sleeve 9 is pushed down so that the abutment rod 10 is inserted into an abutment groove 11. This can limit the plastic expansion plates 4. When expansion is not needed, the plastic expansion plates 4 can be moved into the arc-shaped storage groove 5 for storage, which is quite convenient to use.
[0036] Specifically, the expansion mechanism also includes a plastic connecting plate 2 and a threaded cylinder 12. The plastic connecting plate 2 is fixedly installed between two adjacent main plastic frame plates 1. The sleeve 9 is slidably sleeved on the outside of a plastic connecting plate 2. The threaded cylinder 12 is threadedly installed on the outside of a plastic connecting plate 2. The bottom of the threaded cylinder 12 abuts against the sleeve 9.
[0037] Through the aforementioned extension mechanism, rotating the threaded cylinder 12 can tighten the sleeve 9, ensuring stable positioning of the plastic extension plate 4.
[0038] Specifically, the plastic extension board 4 has a fan-shaped structure, and multiple arc-shaped storage slots 5 are opened on the outer side of the main plastic frame board 1. The plastic extension board 4 is located in the arc-shaped storage slots 5. It should be noted that when expansion is not needed, the plastic extension board 4 can be easily stored.
[0039] Specifically, a plastic extension board 4 has multiple abutment grooves 11 on its top, and the abutment rod 10 is engaged with the abutment grooves 11. It should be noted that this facilitates the limiting treatment of the plastic extension board 4.
[0040] Specifically, a rotating head 13 is fixedly installed at the bottom of the intermediate shaft 6. It should be noted that the intermediate shaft 6 is rotated by the rotating head 13.
[0041] Specifically, there are multiple plastic extension plates 4, which are arranged in a ring with equal spacing. There are also multiple auxiliary gears 8, which are arranged in a ring with equal spacing. It should be noted that the positions of the plastic extension plates 4 and the auxiliary gears 8 are limited.
[0042] Working principle:
[0043] S1: When it is necessary to expand the plastic frame, rotate the middle shaft 6. The middle shaft 6 drives the main gear 7 to rotate, the main gear 7 drives the auxiliary gear 8 to rotate, the auxiliary gear 8 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives multiple plastic expansion plates 4 to rotate. Adjust the size of the plastic expansion plates 4 moving out of the arc-shaped storage slot 5 according to actual needs.
[0044] S2: Push the sleeve 9 downwards so that the abutment rod 10 engages in an abutment groove 11. Rotating the threaded cylinder 12 can tighten the sleeve 9, thus limiting the position of the plastic extension plate 4. Figure 1 and Figure 2 As shown, this is the state where the plastic extension plate 4 extends to its maximum area, which is the state of maximum extension and can increase the overall usable space of the plastic frame.
[0045] S3: When expansion is not required, rotating the intermediate shaft 6 can move the plastic expansion board 4 into the arc-shaped storage slot 5 for storage, making switching convenient.
[0046] The above provides a detailed description of an easily expandable plastic frame provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
