Description

Technical Field

[0001] This utility model relates to the field of pull-out baskets for tall cabinets, and in particular to a pull-out basket structure for tall cabinets. Background Technology

[0002] Pull-down baskets for tall cabinets are primarily used as part of kitchen wall cabinets. To maximize storage space in a limited kitchen, wall cabinets are typically installed. However, due to their height, storing utensils is inconvenient. Therefore, pull-down baskets are installed on these wall cabinets. A lift mechanism on one side of the basket moves the arm to raise and lower it, facilitating storage. Traditional pull-down baskets suffer from short lifespans because the front and rear arms are in direct surface contact with the connecting rods. This leads to wear and tear during the pull-down motion. Furthermore, the pull rods, which are directly screwed to the side panels of the basket, can loosen with frequent use, further contributing to their short lifespan. Utility Model Content

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In this utility model, it should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] A tall cabinet pull-down basket structure, such as Figure 1 - Figure 3 As shown, the device includes a front swing arm 1 and a rear swing arm 2 extending from one side of the elevator, a swing arm connecting rod 3 fixed on the basket, swing arm mounting holes 4 provided at the ends of the front and rear swing arms, connecting rod mounting holes 5 provided at both ends of the swing arm connecting rod, a pivot connector 6 passing through the swing arm mounting holes to hinge the front and rear swing arms to the connecting rod mounting holes at both ends of the swing arm connecting rod, and a pivot sleeve 7 installed on the pivot connector between the front and rear swing arms and the swing arm connecting rod to separate the front and rear swing arms from the swing arm connecting rod.

[0028] like Figures 6-7As shown, the side panels 12 on both sides of the pull-out basket 11 are respectively fixedly installed with lifting mechanisms 13 by screws or bolts. Synchronizing rods 14 are provided on both sides of the lifting mechanisms. One end of the synchronizing rod is fixedly installed on the left rear swing arm 2 by screws or bolts, and the other end is fixedly installed on the right rear swing arm 2 by screws or bolts. The swing arm connecting rod is fixedly installed on the side panel 12 by screws or bolts. One end of the front swing arm 1 and the rear swing arm 2 extends into the lifting mechanism and is hinged inside the lifting mechanism, while the other end is hinged to the swing arm connecting rod through the rotating shaft connector 6. When the front and rear swing arms rotate hinged to the swing arm connecting rod, the rotating shaft sleeve separates the front and rear swing arms from the swing arm connecting rod, thereby avoiding direct surface contact between the front and rear swing arms and the swing arm connecting rod, reducing wear, and thus improving the service life of the pull-out basket.

[0029] like Figures 2-3 As shown, the pivot connector 6 can be made of rivets. The rivet head 61 is located on one side of the swing arm mounting hole. The rivet shank 62 passes through the swing arm mounting hole and a pivot sleeve is fitted on the rivet shank. The rivet head 63 passes through the connecting rod mounting hole and is riveted to the rod wall of the swing arm connecting rod, thereby hinged one end of the front swing arm 1 and the rear swing arm 2 to the swing arm connecting rod. In addition, fitting a pivot sleeve on the rivet shank can effectively separate the front swing arm and the rear swing arm from the swing arm connecting rod.

[0030] In addition, such as Figure 5 As shown, a countersunk step 51 for riveting rivet heads is provided on the connecting rod mounting hole. When riveting, the rivet head can be embedded in the countersunk step, which not only improves the stability of the rivet, but also further enhances the aesthetics of the product.

[0031] In addition, such as Figure 4 As shown, the hinge sleeve is made of plastic, and one end of the hinge sleeve has a connecting part 71 that fits into the swing arm mounting hole. Because the hinge sleeve is made of plastic, friction between hard metal materials is avoided, thus improving the service life of the pull-down basket. The outer diameter of the connecting part is slightly smaller than the outer diameter of the hinge sleeve, fitting perfectly into the swing arm mounting hole, thereby effectively fixing the hinge sleeve, preventing misalignment and loosening, and extending its service life.

[0032] The pivot connector is a rivet. The rivet head is located on one side of the connecting rod mounting hole. The rivet shank passes through the connecting rod mounting hole and is fitted onto the pivot sleeve. The rivet head protrudes from the swing arm mounting hole and is riveted to the swing arm wall. Similarly, one end of the front swing arm 1 and the rear swing arm 2 can be hinged to the swing arm connecting rod. The swing arm mounting hole is provided with a countersunk step for riveting the rivet head. When riveting, the rivet head can be embedded in the countersunk step, which not only improves the stability of the rivet but also further enhances the aesthetics of the product. The pivot sleeve is made of plastic. One end of the pivot sleeve is provided with a connecting part that embeds into the connecting rod mounting hole, which can also avoid friction between hard metal materials, thereby improving the service life of the high cabinet pull-down basket.

[0033] like Figures 9-10 As shown, the pull-down basket structure of the tall cabinet also includes a pull rod 8 located at the bottom of the basket. Each end of the pull rod has a locking foot 81. The side panels on both sides of the basket, which engage with the locking feet, have locking holes 9 for inserting the locking feet. Both ends of the pull rod are fixed to the side panels 12 of the basket 11 with screws. After the locking feet 81 are inserted into the locking holes 9 at both ends of the pull rod, the screws are tightened. When the basket is pulled, the pull rod is less likely to rotate relative to the screws, thus further improving the service life of the tall cabinet pull-down basket. Furthermore, each end of the pull rod has two locking feet, and each side panel has two locking holes for inserting the two locking feet. The combination of the two locking feet and two locking holes provides better fixation of the pull rod, further improving the service life of the tall cabinet pull-down basket.

[0034] like Figure 9 As shown, the pull-down basket structure of the tall cabinet also includes slots 10 at the bottom of the front and rear panels of the basket for engaging the base plate 15. The top of the slot has corrugated portions 101, and the surface of the base plate engaging with these corrugated portions also has corrugated portions. After the base plate is inserted into the slot, the corrugated portions on its surface interlock with the corrugated portions 101, preventing the base plate from falling off and further improving the service life of the pull-down basket.

[0035] The above embodiments are only used to illustrate the detailed solution of this utility model. This utility model is not limited to the above detailed solution, that is, it does not mean that this utility model must rely on the above detailed solution to be implemented. Those skilled in the art should understand that any improvement to this utility model, equivalent substitution of the raw materials of this utility model product, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of this utility model.
