Description

Technical Field

[0001] This utility model relates to the field of pull-out basket cover technology, specifically a novel three-sided pull-out basket cover. Background Technology

[0002] Pull-out baskets are used in cabinets to store bowls, plates, tableware, and other items. The bottom of the pull-out basket is equipped with a support plate and is connected to the slide rail via a sliding rail connector. The pull-out basket can be easily pulled out by sliding along the slide rail, and the connector is usually fixed with screws.

[0003] Existing three-sided pull-out baskets are typically installed by fixing the basket body to the slide rail with screws. To enhance structural stability, some pull-out baskets have metal covers installed on the bottom or sides of the body for auxiliary connection and protection. However, with the screws directly exposed on the upper surface of the metal cover, the following problems arise: 1. Not only does it damage the overall flatness and aesthetics, but it also easily accumulates dust and stains, making it difficult to clean; especially in an environment like the kitchen, where metal screws are easily corroded by moisture and oil.

[0004] 2. Since most traditional cover plates are flat, the screws lack buffer or elastic structure during the fixing process, which can easily cause loosening due to vibration, uneven force and other factors. This affects the connection stability between the pull-out basket and the slide rail. Moreover, the screws are raised and uneven, making it difficult to completely wipe away the dirt around the screws during daily cleaning.

[0005] For example, patent document number CN223232370U discloses a three-sided pull-out basket with a built-in sliding rail protective cover; this patent is the applicant's prior application, but its screws are still directly exposed on the upper surface of the cover plate, which has the above-mentioned technical problems. Therefore, the applicant has made improvements to it and proposed a new type of three-sided pull-out basket with a new cover plate. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of three-sided pull-out basket with a cover plate. By setting a rectangular groove and a structure with elastic oblique folded edge on the cover plate, the installation screws can be hidden in the groove. During the tightening process, the elastic deformation of the oblique folded edge plays a buffering and limiting role, thereby preventing the screws from loosening and improving the stability and reliability of the connection between the pull-out basket and the slide rail. This can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A novel three-sided pull-out basket with a cover plate, comprising a basket body, a cover plate, and a slide rail. Cover plates are respectively provided on the bottom of the left and right sides of the basket body. The cover plates are connected to the slide rail by mounting screws. A rectangular groove is provided on the upper surface of the cover plate, and downward-facing beveled edges are provided on both sides of the rectangular groove. The beveled edges have a certain degree of elasticity, so that loosening does not occur when the mounting screws are tightened to the slide rail. An adjustment gap is provided between the horizontal beveled edges. The lower end of the mounting screw passes through the adjustment gap and is fixedly connected to the slide rail. The threaded end of the mounting screw is located in the rectangular groove, so that the mounting screw does not leak. On the outside of the cover plate, a rectangular cover is provided to protect the mounting screws, reducing the impact of the external environment on the screws, such as the corrosive effect of water on the screws and preventing the accumulation of stains, and making the appearance more aesthetically pleasing. Compared with the mounting screws being exposed on the cover plate, the flat cover plate is also easier to wipe. The rectangular cover has inclined structures on both sides corresponding to the inclined sections of the slanted edges. One side of the rectangular cover has a limiting protrusion, and the other side of the limiting protrusion has a guide inclined protrusion. The limiting protrusion is locked into one side of the rectangular groove to prevent the rectangular cover from accidentally falling off and to ensure structural stability. The guide inclined protrusion facilitates the installation of the rectangular cover.

[0008] Furthermore, an arc-shaped groove is provided on the inner side of the rectangular cover. This arc-shaped groove is used to increase the space under the rectangular cover, leaving enough space for the screw caps to be installed. The rectangular groove is formed by punching with a punching machine.

[0009] Furthermore, the cover plate is made of stainless steel, while the rectangular cover is made of plastic.

[0010] Furthermore, a slide rail tail clip assembly is provided at the outer end of the cover plate. The slide rail tail clip assembly includes a tail clip cover, a baffle is provided on the front side of the tail clip cover, a slot is provided between the baffle and the tail clip cover, a top groove is provided on the top of the tail clip cover, a folded edge hook is provided on the cover plate, the folded edge hook is inserted into the slot, and a tail hook is provided on the upper rail of the slide rail, the tail hook is inserted into the top groove, and the width of the top groove is greater than the width of the tail hook.

[0011] Furthermore, a second slot is provided on the folded edge hook, a locking block is provided on the baffle, the locking block is located in the second slot, and a vertical thin protrusion is provided on the inner side of the baffle.

[0012] Furthermore, a vertical soft rubber sleeve is fitted on the vertical section of the tail hook, and a horizontal soft rubber sleeve is fitted on the horizontal section of the tail hook. A horizontal protrusion is provided on the inner wall of the top groove, and the horizontal protrusion contacts the horizontal soft rubber sleeve.

[0013] Furthermore, ear plates are provided on the side of the cover plate, and positioning holes are provided on the upper surface of the cover plate. The lower end of the basket body is inserted into the positioning holes, and the vertical ribs of the basket body are welded and fixed to the ear plates.

[0014] Furthermore, the ear plate is stamped with a protrusion, which is welded and fixed to the transverse rib of the basket body.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. A rectangular recess and a structure with elastic beveled edges are provided on the cover plate so that the mounting screws can be hidden in the recess. During the tightening process, the elastic deformation of the beveled edges plays a buffering and limiting role, thereby preventing the screws from loosening and improving the stability and reliability of the connection between the pull basket and the slide rail.

[0016] 2. A rectangular cover is installed outside the screw installation location. This not only prevents the screw from being exposed and causing unsightly damage, but also effectively blocks external factors such as moisture and oil from corroding the screw, significantly extending the service life of the screw and the entire device. At the same time, the small cover is reliably fixed by limiting convex strips and guide convex strips to prevent accidental detachment.

[0017] 3. The cover plate features a flat surface design and utilizes a well-chosen combination of stainless steel and plastic materials. This ensures both the strength and corrosion resistance of the overall structure while enhancing the cleanliness and aesthetics of the appearance. The flat surface facilitates daily cleaning, reduces stain accumulation, and improves the user experience. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. Example

[0025] Please see Figure 1-10 This utility model provides a technical solution: a novel three-sided pull-out basket with a cover plate, comprising a basket body 1, a cover plate 4, and a slide rail 3. Cover plates 4 are respectively provided on the bottom of the left and right sides of the basket body 1. The cover plates 4 are connected to the slide rail 3 by mounting screws 5. A rectangular recess 16 is provided on the upper surface of the cover plate 4. The two sides of the rectangular recess 16 are provided with downward-facing inclined edges 23. The inclined edges 23 have a certain elasticity and will not loosen when the mounting screws 5 are tightened to the slide rail 3. An adjustment gap 24 is provided between the inclined edges 23 in the horizontal direction. The lower end of the mounting screw 5 passes through the adjustment gap 24 and is fixedly connected to the slide rail 3. The thread of the mounting screw 5 is located within the rectangular recess. In the groove 16, the mounting screw 5 is not exposed outside the cover plate 4; a rectangular cover 22 is provided on the cover plate 4, which protects the mounting screw 5, reduces the impact of the external environment on the mounting screw 5, improves the appearance, and the flat cover plate 4 is easy to wipe; the rectangular cover 22 has inclined structures on both sides corresponding to the inclined section of the inclined folded edge 23, a limiting protrusion 26 is provided on one side of the rectangular cover 22, and a guide inclined protrusion 25 is provided on one side of the limiting protrusion 26. The limiting protrusion 26 is stuck on one side of the rectangular groove 16 to prevent the rectangular cover 22 from falling off accidentally, and the guide inclined protrusion 25 facilitates the smooth installation of the small cover 22.

[0026] In another possible implementation, an arc-shaped groove 27 is provided on the inner side of the rectangular cover 22. The arc-shaped groove 27 is used to increase the space under the rectangular cover 22, leaving enough space for the screw cap 5 to be installed, and avoiding interference between the small cover 22 and the screw cap. At the same time, the rectangular groove 16 is stamped by a punching machine to ensure processing accuracy and consistency.

[0027] In another possible implementation, the cover plate 4 is made of stainless steel, which has excellent corrosion resistance and mechanical strength, and is suitable for long-term use in humid environments; the rectangular cover 22 is made of plastic, which is lightweight, easy to process, and can effectively cover and protect the screws 5.

[0028] The core principle of this three-sided pull-out basket is that a stable installation structure is formed by the rectangular recess 16 and the elastic beveled edge 23. During the tightening process, the mounting screw 5 achieves the anti-loosening function by adjusting the gap 24 and the elasticity of the beveled edge 23, and the screw head is stored inside the recess 16 to avoid exposure. The rectangular cover 22 achieves stable installation through the limiting protrusion 26 and the guide bevel 25. At the same time, the arc-shaped groove 27 provides extra space for the screw cap to ensure smooth installation. The overall structure not only ensures the fastening effect of the cover plate 4 and the slide rail 3, but also takes into account the flat appearance and ease of cleaning.

[0029] This embodiment effectively solves the problems of loose screws, exposed screws affecting aesthetics, and easy corrosion in the installation of traditional pull-out basket covers; the combination of the recessed groove 16, the beveled edge 23, and the adjustable gap 24 improves the reliability of installation; the covering of the small cover 22 and the spatial design of the groove 27 enhance the protective performance and maintain a clean appearance; the reasonable selection of materials achieves a balance between structural strength and cost control; this invention is particularly suitable for humid and complex environments such as kitchens and bathrooms, with a longer service life and more convenient cleaning and maintenance.

[0030] The rectangular recess 16 can be designed with different depths or shapes according to different screw sizes; the elasticity of the beveled edge 23 can be adjusted by different thicknesses or angles; the width of the adjustable gap 24 can be appropriately enlarged to accommodate different models of slide rails 3; in addition to the snap-fit ​​structure, the rectangular cover 22 can also be fixed by sliding insertion or magnetic attraction, and the material can be metal, composite material or rubber in addition to plastic to improve the protective performance; the cover plate 4 can be replaced by aluminum alloy, galvanized steel plate or carbon steel to meet different usage scenarios or cost requirements; in addition to the punching process, the rectangular recess 16 can also be realized by laser cutting, CNC milling or mold forming methods.

[0031] A slide rail tail clamp assembly 2 is provided at the outer end of the cover plate 4. The slide rail tail clamp assembly 2 includes a tail clamp cover 12. A baffle 15 is provided on the front side of the tail clamp cover 12. A slot 14 is provided between the baffle 15 and the tail clamp cover 12. A top groove 20 is provided on the top of the tail clamp cover 12. A folded edge hook 9 is provided on the cover plate 4. The folded edge hook 9 is inserted into the slot 14. The folded edge hook 9 plays a role in bearing the force in the front and rear directions of the pull basket body 1 to prevent the pull basket body 1 from detaching from the slide rail 3. A tail hook 6 is provided on the upper rail of the slide rail 3. The slide rail 3 is generally composed of an upper rail and a lower rail. The rail is fixed to the wall panel, and the upper rail and the lower rail roll in contact. The tail hook 6 is inserted into the top groove 20. The width of the top groove 20 is greater than the width of the tail hook 6. The tail hook 6 can be adjusted left and right in the top groove 20, so that the tail of the slide rail 3 can be adjusted left and right. The baffle 15 and the tail hook 6 cooperate to block and ensure the safety of the structure. The tail cover 12 is connected through the tail hook 6 and the folded edge hook 9. The tail cover 12 also blocks the tail hook 6 and the folded edge hook 9 and makes the cover plate 4 reliably connected to the slide rail 3.

[0032] The folding hook 9 is provided with a second slot, and the baffle 15 is provided with a block 8. The block 8 is located in the second slot. This structure enhances the connection strength between the tail cover 12 and the cover plate 4, prevents the tail cover 12 from detaching, and has higher structural strength. The inner side of the baffle 15 is provided with a vertical thin protrusion 13, which increases the friction of the folding hook 9.

[0033] A vertical soft rubber sleeve 7 is fitted on the vertical section of the tail hook 6. The vertical soft rubber sleeve 7 can provide elastic deformation to keep the pull basket body 1 and the slide rail 3 in close contact. A horizontal soft rubber sleeve 10 is fitted on the horizontal section of the tail hook 6. A horizontal protrusion 11 is provided on the inner wall of the top groove 20. The horizontal protrusion 11 contacts the horizontal soft rubber sleeve 10. The horizontal protrusion 11 and the horizontal soft rubber sleeve 10 increase the friction and prevent slippage.

[0034] The cover plate 4 has an ear plate on its side and a positioning hole on its upper surface. The lower end of the basket body 1 is inserted into the positioning hole, which serves to position the basket and ensure that the position is correct. The basket body 1 is then connected by argon arc welding to increase its strength. The vertical ribs of the basket body 1 are welded and fixed to the ear plate.

[0035] The ear plate is stamped with a protrusion, which is welded and fixed to the horizontal rib of the basket body 1. The load-bearing capacity of the basket body 1 is increased by spot welding. Corner support ribs are added to the basket body 1 and connected by spot welding and argon arc welding to enhance the strength of the rear two corners. This part is a reinforcement structure and is a conventional technology, so it will not be described in detail here.

[0036] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this utility model as claimed.
