Description

Technical Field

[0001] This utility model relates to the field of plastic frame technology, and more specifically, to a reinforcing structure for plastic frames. Background Technology

[0002] Plastic frames, as a lightweight, durable and easy-to-process material, are widely used in packaging, logistics, agriculture and other fields. With the development of the global economy and the improvement of people's living standards, the market demand for plastic frames continues to grow, especially in the packaging industry, where plastic frames have become an indispensable component.

[0003] There are many types of plastic frames on the market. Currently, most plastic frames have corresponding compressive strength reinforcement structures, giving them advantages such as high structural strength and resistance to deformation. Most plastic frames also have handles. However, since the handles are the components that bear stress, the handle parts of most plastic frames are integrally molded onto the frame, resulting in the drawback that the handles cannot be removed and replaced. When the handle is damaged, the entire plastic frame becomes unusable, leading to resource waste. Therefore, we propose a reinforcement structure for plastic frames. Utility Model Content

[0004] The purpose of this invention is to provide a reinforced structure for plastic frames to address the deficiencies mentioned in the background art.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model significantly improves the structural strength of the plastic frame by setting a top reinforcing frame and corner anti-compression beams, effectively enhancing its ability to bear heavy objects and resist external impacts. At the same time, the multiple vertical and horizontal beams set on each side plate further enhance the overall rigidity and stability of the frame, ensuring the durability of the plastic frame in various usage environments. The design of the anti-compression lid not only provides an extra protective layer for the plastic frame, but the longitudinal and transverse beams on it also enhance the anti-compression performance of the lid, making the entire plastic frame structure more robust and durable, achieving the effect of a solid and stable structure and improved anti-compression performance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 The present invention provides a technical solution: a reinforced structure for a plastic frame, including a plastic frame body 1, a top reinforcing frame 10 integrally formed at the top position of the plastic frame body 1, and two symmetrical hard threaded sleeves 101 fixedly installed in the left and right side plates of the top reinforcing frame 10. The hard threaded sleeves 101 are integrally formed in the top reinforcing frame 10, making the structure of the hard threaded sleeves 101 part more solid and stable.

[0029] Specifically, handles 31 are provided on both the left and right side plates of the top reinforcing frame 10. Handle brackets 3 are fixedly installed on the side of the handles 31. The handle brackets 3 have slots 30 that are connected to the outside at the bottom. The slots 30 are engaged with the top reinforcing frame 10. The handle brackets 3 and the hard threaded sleeve 101 are fixedly connected by fastening screws, which facilitates fixed installation and disassembly and replacement operations, so as to achieve the effect of replacing the damaged handles 31.

[0030] In this embodiment, the bottom of the plastic frame 1 is integrally formed with a bottom wear-resistant plate 11. The bottom wear-resistant plate 11 has good wear resistance, is not easily worn, and helps to extend its service life.

[0031] Specifically, corner anti-compression beams 12 are integrally formed at the four corners of the plastic frame 1. The cross-section of the corner anti-compression beams 12 is L-shaped, which enhances the compressive strength and structural stability of the corners of the plastic frame 1, effectively resists external impact and heavy object pressure, and extends the service life of the plastic frame.

[0032] Furthermore, each side panel of the plastic frame 1 is provided with multiple vertical beams 13 and multiple horizontal beams 14, which further enhances the overall strength and rigidity of the plastic frame 1, making the plastic frame 1 more stable when bearing heavy objects and less prone to deformation or damage.

[0033] In addition, a pressure-resistant cover 2 is provided at the top of the plastic frame 1. The pressure-resistant cover 2 is fitted onto the top reinforcing frame 10, providing an additional protective layer for the plastic frame 1 and enhancing the pressure resistance of the top of the plastic frame 1, making the plastic frame 1 safer and more reliable when stacking or placing heavy objects. Multiple longitudinal beams 20 and multiple transverse beams 21 are integrally formed on the top plate of the pressure-resistant cover 2, which enhances the strength and stability of the pressure-resistant cover 2, improves the overall pressure resistance of the plastic frame 1, and enables the plastic frame 1 to maintain structural integrity even under extreme conditions.

[0034] It is worth noting that a threaded drain hole 4 is provided on one side plate of the plastic frame 1. The threaded drain hole 4 is located near the bottom of the plastic frame 1, which facilitates the drainage of water accumulated inside the plastic frame 1 and improves the practicality and hygiene of the plastic frame 1. A threaded plug 40 is connected to the threaded drain hole 4 by a threaded thread. A pressure plate 41 is fixedly installed at the end of the threaded plug 40. A knob 42 is fixedly installed on the side of the pressure plate 41, which makes it more convenient to open and close the threaded drain hole 4. Users can easily open or close the threaded drain hole 4 by rotating the knob 42. At the same time, the design of the pressure plate 41 ensures the sealing of the threaded drain hole 4 when it is closed.

[0035] It is worth noting that a sealing ring 43 is fitted on the threaded plug 40, and the pressing plate 41 presses the sealing ring 43 against the outer surface of the plastic frame 1, which further enhances the sealing performance of the threaded drain hole 4, effectively prevents the leakage of water or other liquids, and improves the waterproof performance and durability of the plastic frame 1.

[0036] When the reinforced structure of the plastic frame of this utility model is in use, the items are placed inside the plastic frame 1, and the vertical beam 13, horizontal beam 14 and corner anti-compression beam 12 provide anti-compression support. After the anti-compression box cover 2 is closed, multiple plastic frames 1 can be stacked on top of each other.

[0037] When it is necessary to move or transport the plastic frame 1, the user can hold the handle 31 to perform the transfer operation. The handle 31 is fixedly connected to the plastic frame 1 by the fastening screw between the handle seat 3 and the hard threaded sleeve 101. If the handle 31 is damaged, the user can easily replace it by removing the fastening screw.

[0038] When water needs to be drained from inside the plastic frame 1, the user can easily open the threaded plug 40 by rotating the knob 42 on the threaded drain hole 4, allowing the water to drain smoothly. After the drainage is complete, rotate the knob 42 to close the threaded drain hole 4. At this time, the pressure plate 41 and the sealing ring 43 will ensure the sealing of the drain hole and prevent the leakage of water or other liquids.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
