Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, and in particular relates to a plastic corner protector for preventing scratches on the shell. Background Technology

[0002] In the production process, the turnover of semi-finished products plays a crucial role, affecting multiple aspects such as production continuity, efficiency, cost, and quality. A good semi-finished product turnover system enables enterprises to cope with sudden changes in production demand or orders to a certain extent. The production process is usually carried out in stages, and the effective turnover of semi-finished products ensures a sufficient supply of raw materials for the next stage of production, avoiding production interruptions due to a lack of semi-finished products, and making the production process more efficient and orderly. Timely turnover of semi-finished products to the next production stage can reduce waiting time, shorten the production cycle, and improve overall production efficiency. At the same time, strict management and inspection of semi-finished products can promptly identify and correct problems that arise during production, ensuring stable and improved product quality. If quality defects are found in semi-finished products during turnover, they can be dealt with promptly to prevent them from flowing into subsequent processes and affecting the quality of the final product.

[0003] Chinese patent document CN214675397U discloses a stacking corner protector for television back panels, comprising a main body, a positioning post on one side of the main body, and a positioning groove on the other side of the main body. The positioning groove and the positioning post are located on the same axis, and a limiting groove is provided on one side of the main body. When two main bodies are stacked, the positioning post can be inserted into the positioning groove. During the stacking process of the back panels, the main body is first fixed on a tray and placed according to the four corners of the back panel. Then, the four corners of the back panel are inserted into the limiting groove to protect the corners of the back panel and prevent deformation or damage to the corners due to vibration and impact during transportation. At the same time, after the first back panel is placed, the positioning groove of the other main body is aligned with the positioning post of the previous main body and inserted into it, thereby completely covering the four corners of the first back panel to form a limiting space and preventing displacement during transportation.

[0004] In practical applications, within a reasonable height range, the more stacked layers there are, the higher the turnover efficiency. However, in actual use, it is often necessary to split a single stack of back panels into two or more stacks, such as distributing the single stack of back panels to two production lines and removing them one by one for subsequent processing. Reducing the number of stacked layers can provide convenience for subsequent production operations. The four corner protectors are distributed at the four corners of the back panel. Unsynchronized movement of the four corner protectors can cause the back panel to twist, tilt, or even be damaged, while the corner protectors bear the entire weight of the upper layer of products. In the patented solution mentioned above, the interlocking between adjacent corner protectors is tight with no gaps in between, making disassembly extremely inconvenient. Utility Model Content

[0005] To overcome the technical problem in existing technologies where corner protectors are stacked too tightly when splitting a single stack of products into two or more stacks, making it inconvenient to separate adjacent corner protectors, this invention aims to provide a plastic corner protector for preventing scratches on the casing. This is achieved by setting three uprights on the corner protector, located at the two ends of the right-angle panel and at the corner, with gaps between adjacent uprights. These gaps facilitate tool insertion and handling, allowing for easy separation of two adjacent corner protectors and facilitating the disassembly of stacked products.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a plastic corner protector for preventing scratches on the shell, comprising a base plate and a right-angled perimeter plate disposed on the upper outer perimeter of the base plate; a column is disposed on the upper end of the base plate at both ends of the right-angled perimeter plate and at the right-angled corner; a positioning post is longitudinally disposed on the upper end of the column; three positioning holes are disposed on the lower end of the base plate, each coaxially disposed with the three positioning posts; the outer diameter of the positioning post is equal to the inner diameter of the corresponding positioning hole; wherein, the height of the column is greater than the height of the right-angled perimeter plate; a gap is disposed between the column at the right-angled corner and the two adjacent columns.

[0007] Furthermore, the thickness of the uprights at both ends of the right-angled enclosure is greater than the thickness of the right-angled enclosure; the upright at the right-angled corner is fitted with the inner wall of the right-angled enclosure; and a receiving cavity is formed between the three uprights.

[0008] The accommodating cavity provides space for the corners of the shell placed on the corner protectors, effectively preventing the corners of the shell from being bumped or deformed.

[0009] Specifically, the two columns at the ends of the right-angled enclosure are provided with inclined plates that are narrower at the top and wider at the bottom; the inclined plates are perpendicular to the adjacent right-angled enclosure.

[0010] The two inclined plates and the right-angled enclosure form a rectangular reinforced structure, which makes the corner guards more stable under force and the structure stronger. At the same time, the inclined plates also provide guidance for the placement of the shell, which facilitates the placement of the shell and also makes the gap between the shell and the corner guards smaller, preventing the shell from shaking or moving during turnover.

[0011] Specifically, the upper end of the substrate is provided with three recessed cavities; one of the recessed cavities is located at the inner bottom of the receiving cavity, and the other two recessed cavities are located on the side of the inclined plate away from the adjacent column.

[0012] The recessed cavity reduces the contact area with the housing parts, preventing scratches and wear on the surface of the housing parts.

[0013] Optionally, a flexible pad may be detachably connected to the recessed cavity.

[0014] When applied to parts with high requirements for surface quality or fragile surfaces, such as glass products, flexible pads can be added to increase the product's protective capabilities.

[0015] Preferably, the sidewall of the column is a tapering surface that gradually decreases in size from bottom to top.

[0016] The contraction surface creates a noticeable protruding outer edge at the lower end of the upper corner protector between two adjacent corner protectors, facilitating the counting of the number of layers and making it easier to separate the upper and lower corner protectors.

[0017] Furthermore, the outer diameter of the columns at both ends of the right-angle panel is greater than the outer diameter of the column at the right-angle corner.

[0018] Furthermore, the substrate is rectangular in shape; a rectangular chamfer is provided at one corner of the substrate away from the right-angled enclosure.

[0019] Specifically, the thickness of the right-angled partition is greater than the thickness of the substrate.

[0020] Specifically, the lower end of the substrate is provided with a grid-shaped rib.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model provides support columns at both ends and corners of a right-angled panel, and gaps between adjacent columns to facilitate the insertion or handling of tools, allowing the upper and lower corner protectors to be easily separated, and facilitating the disassembly of stacked turnover items.

[0023] 2. By setting the shrinkable surface and the inclined plate, this utility model forms a stable structural support between the right-angled panel and the column, resulting in higher overall strength and stronger resistance to deformation. The shrinkable surface makes the upper layer of the upper and lower corner protectors have obvious lower eaves, which is convenient for counting the number of layers and for separating the upper and lower layers. The inclined plate not only facilitates the placement of turnover items such as shells, but also makes the gap between the placed turnover items and the corner protectors smaller, preventing shaking during turnover.

[0024] 3. This utility model can prevent the corners of the shell from being bumped by setting up a receiving cavity; the recessed cavity can prevent the shell surface from being worn; and the addition of a flexible pad can protect turnover products with high surface quality requirements or fragile items.
