Technical Field
[0001] The utility model relates to the technical field of furniture, in particular to a drawer connection structure and a cabinet. Background Art
[0002] At present, kitchen islands are often provided. The island can provide a working surface for operation, facilitating the placement of items on it. Further, the height of the island is relatively high, occupying a large three-dimensional space, and it only has the function of providing a working surface, so the space utilization rate of the island is relatively low. To increase the functions of the island, it is usually transformed into a cabinet. Specifically, two-way drawers are installed on the island to facilitate access to items from both sides of the island. And a transparent plate is provided above the drawers, enabling users to observe the items stored in the drawers through the transparent plate above the island for convenient use. However, since the entire drawer can be seen from above, it is also very easy to see mechanical components such as guide rails provided on the side of the drawer, reducing the visual effect of the island, thereby reducing the user experience. Further, for convenience, such two-way drawers generally do not have a locking structure. Therefore, it is difficult for users to push them to the exact middle every time they are used, and the drawers are prone to protruding to one side. This not only further reduces the visual effect of the island but also continuously exposes the items in the drawers, thus contaminating the items and ultimately resulting in a poor user experience.

[0024] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.
[0025] Such as Figures 1 to 4As shown, a drawer connection structure 22 of the present utility model includes a bottom assembly 221, a sliding frame 222 and an intermediate buffer damper 225. The bottom assembly 221 includes a bottom plate 2211 and guide rails 2212. The guide rails 2212 are arranged along the front-back direction on the top surface of the bottom plate 2211. The sliding frame 222 is slidably connected to the guide rails 2212 along the front-back direction. The intermediate buffer damper 225 includes a fixed block 2251 and a damper block 2253. The fixed block 2251 is arranged on the top surface of the bottom plate 2211. The damper block is fixedly connected to the sliding frame. A slot is provided on the side surface of the damper block 2253 opposite to the fixed block 2251. The slot is located in the middle of the sliding frame 222 along the front-back direction. The damper block 2253 is made of a soft material. When the sliding frame 222 moves along the front-back direction, the fixed block 2251 and the damper block 2253 are mutually extruded, so that the fixed block 2251 slides into the slot and disengages from the slot.
[0026] The drawer connection structure 22 in the above technical solution includes a bottom assembly 221 fixed to the cabinet body 1 and a slidable sliding frame 222 connected to the drawer body 21. Among them, the bottom plate 2211 is slidably connected to the sliding frame 222 along the front-back direction by arranging guide rails 2212 extending along the front-back direction, so that the sliding frame 222 can move along the front-back direction, and further realizes the function that the drawer fixedly connected to the sliding frame 222 can be pulled out along the front-back direction. And because the bottom assembly 221 and the sliding frame 222 are arranged from bottom to top, the components of the drawer connection structure 22 are all hidden below the drawer, so that the user cannot observe the specific structure of the drawer connection structure 22 from above, which can improve the visual experience of the product; further, the damper block 2253 and the fixed block 2251 of the intermediate buffer are respectively arranged on the sliding frame 222 and the bottom plate 2211 and are arranged corresponding to each other. When the user pushes the drawer towards the middle, the sliding frame 222 moves along the front-back direction, the damper block 2253 moves towards the position of the fixed block 2251, the fixed block 2251 and the damper block 2253 are mutually extruded, the damper block 2253 deforms and provides a certain damping, so that the user knows that the drawer is about to be pushed to the middle. When the fixed block 2251 slides into the slot, the drawer is located in the middle of the cabinet body 1, and the slot walls on both sides of the slot block the fixed block 2251, so that the sliding frame 222 cannot easily move along the front-back direction, preventing the situation that the drawer protrudes randomly to one side, so that the island platform can maintain a good visual effect, and can prevent the items in the drawer from being continuously exposed. At this time, the user can pull the drawer to make the fixed block 2251 and the damper block 2253 mutually extruded, the damper block 2253 deforms, and then the fixed block 2251 disengages from the slot, realizing the effect of pulling the drawer to one side; In summary, the drawer connection structure 22 of the present utility model can enable the user to have a good use experience.
[0027] Further, the intermediate buffer damper 225 further includes a moving block 2252. The moving block 2252 is fixedly arranged on the sliding frame 222.

A guiding chamfer is provided from the front of the damping block 2253 to the notch of the card slot and from the back of the damping block 2253 to the notch of the card slot. Among them, the damping block 2253 is fixedly arranged in the receiving groove of the moving block 2252 to be more stably connected to the sliding frame. Further, the guiding chamfer can enable the user to push the drawer in more smoothly, further improving the user experience.
[0028] Further, the bottom assembly 221 further includes two one-way buffer dampers 2213. The two one-way buffer dampers 2213 are respectively arranged on the top surface of the bottom plate 2211 facing forward and backward. The sliding frame 222 can move forward until the one-way buffer damper 2213 facing backward abuts against the sliding frame 222, and the sliding frame 222 can move backward until the one-way buffer damper 2213 facing forward abuts against the sliding frame 222. When the sliding frame 222 moves forward or backward to a certain stroke, the corresponding one-way buffer damper 2213 abuts against the sliding frame 222. Since the one-way buffer damper 2213 has a buffering function, it can gradually and slowly prevent the sliding frame 222 from continuing to move, preventing the sliding frame 222 from undergoing a rigid impact, and further reducing the risk of damage to components.
[0029] Further, the one-way buffer damper 2213 includes a cylinder body 22131, a buffer rod 22132, and a buffer spring.

The cylinder body 22131 of the one-way buffer damper 2213 facing forward is located in front of the cylinder body 22131 of the one-way buffer damper 2213 facing backward, so as to avoid the mutual influence of the two one-way buffer dampers and shorten the buffering stroke.
[0031] Further, the bottom assembly 221 further includes two limiting blocks 2214. The two limiting blocks 2214 are arranged on the top surface of the bottom plate 2211 at intervals in the front-rear direction. The limiting blocks 2214 and the one-way buffer damper 2213 are in one-to-one correspondence. The front of one limiting block 2214 is located between the front of the corresponding cylinder body 22131 and the front of the buffer rod 22132 in the front-rear direction, and the rear of the other limiting block 2214 is located between the rear of the corresponding cylinder body 22131 and the rear of the buffer rod 22132 in the front-rear direction.
[0032] Further, it further includes two extension parts 223 and a plurality of rollers 224. The two extension parts 223 are respectively arranged on two opposite side surfaces of the sliding frame 222 in the left-right direction.
