Description

Technical Field

[0001] This utility model relates to the field of cabinet pull-out basket drawer door tilting device, and in particular a drawer door tilting mechanism. Background Technology

[0002] Kitchen cabinet pull-out baskets are drawer-style storage baskets installed in kitchen cabinets for the categorized storage of tableware, cookware, condiments, and other items. Chopsticks and cutlery are frequently accessed from these baskets. To facilitate the storage and retrieval of these utensils, current methods primarily involve installing storage boxes on the inside of the cabinet door. To access these items, the cabinet door and basket are pulled out horizontally together. However, because the door and basket are fixed, pulling the door horizontally with the weight of the dishes and other tableware on the basket is quite strenuous, making it inconvenient for accessing smaller items like chopsticks and cutlery, resulting in a poor user experience. Utility Model Content

[0003] The purpose of this invention is to provide a drawer door tilting mechanism that facilitates the storage and retrieval of small items such as knives, forks, and chopsticks, thereby improving the user experience.

[0004] The drawer door tilting mechanism of this utility model includes a hinge that hinges the cabinet door to the cabinet bottom plate. A sliding groove is provided on the side plate of the cabinet, and a connecting rod that can move back and forth in the sliding groove is installed in the sliding groove. One end of the connecting rod is hinged to the cabinet door, and the top and bottom of the other end are provided with arc-shaped protrusions that can rotate concentrically along a circle when the cabinet door tilts, causing the connecting rod to tilt. An elastic element is installed on the side plate of the cabinet near the end of the arc-shaped protrusion. One end of the elastic element is connected to the connecting rod, and the other end is connected to the side plate of the cabinet. A locking platform is provided between the arc-shaped protrusion at the bottom of the connecting rod and the connecting rod. A buffer limiting element is installed on the side plate of the cabinet near the cabinet door section to abut against the locking platform when the cabinet door tilts and to abut against the cabinet door when the cabinet door is closed.

[0005] The drawer door tilting mechanism of this utility model, when the drawer door is opened, the arc-shaped protrusions at the top and bottom of the connecting rod slide on the slide groove while rotating around the center of the arc-shaped protrusions to compensate for the height position of the drawer door connection end caused by the tilting motion of the drawer door. At the same time, the elastic element is stretched. When the drawer door is almost open to the desired position, the locking plate of the connecting rod begins to contact the buffer limiter, helping the drawer door to decelerate and stop. At this time, the drawer door and the storage box fixed inside the drawer door tilt downwards at a certain angle, which makes it convenient to store and retrieve small items such as knives, forks and chopsticks without the need for horizontal movement. The pull-out basket design makes it more effortless and provides a better user experience. When closing the cabinet door, applying force at the upper edge of the door moves it towards the closed position. The door then comes into contact with the buffer limiter for deceleration. Even when the door is closed, the elastic element remains stretched, providing a closing force that ensures a tighter seal between the door and the basket. Furthermore, the buffer limiter not only restricts the movement of the linkage when the door is open but also cushions the door when it is closed, thus extending the lifespan of both the linkage and the door.

A locking platform 6 is provided between the arc-shaped boss at the bottom of the connecting rod and the connecting rod. A buffer limiting element 7 is installed on the side plate of the cabinet near the cabinet door section, which abuts against the locking platform when the cabinet door is tilted and abuts against the cabinet door when the cabinet door is closed.

[0027] The hinge is selected as the connecting component. One side of the hinge is fixed to the bottom of the cabinet door with screws, and the other side is fixed to the cabinet base plate with screws. The hinge facilitates the downward tilting of the cabinet door 13, further improving the convenience of accessing small items such as cutlery and chopsticks from the storage box 14 inside the cabinet door. Additionally, a connecting piece 10 is fixed to the cabinet door with screws. The connecting piece is vertically oriented, and a connecting lug is integrally formed at the top of the connecting piece, facing the connecting rod. A connecting hole, aligned with the hole on the connecting lug, is provided at the end of the connecting rod near the cabinet door. A pivot is inserted through the connecting hole and hinged to the connecting lug. By inserting a pivot through the connecting hole at the end of the connecting rod and hinged to the connecting lug, the flexibility of downward tilting and rotation is improved, further enhancing the convenience of accessing small items such as cutlery and chopsticks from the storage box inside the cabinet door.

[0028] The elastic element is a spring. A hook 8 is provided on the connecting rod for engaging the elastic element. The hook 8 is located in the middle between the two ends of the connecting rod and is integrally formed with the connecting rod, protruding to one side to form the hook. A fixing seat 9 for fixing the elastic element is provided on the cabinet side panel. The fixing seat is located in the middle between the two ends of the cabinet side panel and uses a connecting rod structure. The connecting rod is located on the slide rail. The top of the connecting rod is screwed to the cabinet side panel at the top of the slide rail, and the bottom of the connecting rod is screwed to the cabinet side panel at the bottom of the slide rail. One end of the spring is secured to the hook, and the other end is screwed to the middle position between the upper and lower ends of the connecting rod.

[0029] A sealing plug 11 is installed on the end of the cabinet side panel near the cabinet door. The buffer limiting component 7 includes an outer sleeve 71 fixed to the cabinet side panel. The outer sleeve 71 is connected to the sealing plug 11 and then fixed to the cabinet side panel by the locking feet and screws of the sealing plug. Figure 4 , Figure 6 and Figure 9 As shown, a cylinder 72 is installed inside the outer sleeve. The cylinder body 73 extends from the outer sleeve toward the cabinet door side as a cylinder body extension section. The piston rod 74 extends from the outer sleeve toward the mounting plate at the bottom of the connecting rod as a piston rod extension section. A connecting rod hole for the connecting rod extension and a cylinder body hole for the cylinder body extension section are pre-drilled in the sealing plug, and a buffer pad 12 is installed at the end of the cylinder body extension section. A soft rubber pad fixing seat 75 is installed on the piston rod. One end of the soft rubber pad fixing seat is fixedly installed on the piston rod section inside the outer sleeve, and the other end is installed on the piston rod extension section. A soft rubber pad 76 is installed on the soft rubber pad fixing seat at the piston rod extension section. A limiting block 77 is installed inside the outer sleeve to allow the cylinder housing to move toward the cabinet door side under the push of the piston rod. The inner side of the limiting block 77 can be fixed to the cabinet side plate on the inner wall of the slide groove with screws. The cylinder body and the cylinder housing are fixedly connected. In addition, the connecting rod is also equipped with an upper locking platform 15, which locks the cabinet door with the sealing plug when the cabinet door is almost open to stop it from tilting downwards.

[0030] The arc-shaped bosses at the top and bottom of the connecting rod slide on the slide groove while rotating around the center of the arc-shaped bosses to compensate for the height position of the cabinet door connection end caused by the tilting of the cabinet door. At the same time, the spring is stretched. When the cabinet door is almost open, the locking platform of the connecting rod begins to contact the soft rubber pad 76. The soft rubber pad 76 compresses the piston rod through the soft rubber pad fixing seat 75. The piston rod moves the cylinder housing and cylinder body towards the cabinet door side. When the cylinder housing is locked at the limit stop 77, the piston rod decelerates within the cylinder, helping to slow down the tilting of the cabinet door. Finally, the upper locking platform 15 of the connecting rod contacts the sealing plug and stops moving. When the cabinet door is closed, the hand applies force on the upper edge of the cabinet door, moving the cabinet door towards the closed position. When it is almost closed, the buffer rubber pad 12 at the end of the cylinder body extension helps to slow down the cabinet door.
