[0002] As people's daily necessities increase in life, if they are not sorted and placed in a unified place, our living environment will become messy and daily necessities will take up a lot of space. Therefore, people often use storage containers to store items in a unified manner and classify and store daily necessities or garbage.

[0003] The importance of storage is particularly reflected in the kitchen. Pull-out baskets are often used in kitchen cabinets to store dishes and cooking utensils, or hidden trash cans are installed in the cabinets in a push-pull installation manner. In the existing cabinet push-pull structure, the metal connectors connecting the door panel structure and the frame structure are the main force-bearing and reinforcing accessories. The door panel connector structure is generally used at the corner between the door panel and the frame. This is a metal connector similar to a reinforcing rib, which is connected between the horizontal cabinet metal frame and the vertical cabinet door panel. In actual installation, due to installation errors, the relative positions of the two still need to be fine-tuned after assembly. In addition, the existing cabinet pull-out connection structure is usually fixed on the inner walls on both sides of the cabinet. When carrying bucket-type tools such as trash cans or storage bins, a connecting plate needs to be set at the rear end of the pull-out structure on both sides. The pull-out structures on both sides and the connecting plates are combined to form a frame for placing bucket-type tools. In the actual installation process, due to the different specifications and sizes of the cabinets, the pull-out structure of the cabinet can be installed on the inner walls on both sides of the cabinet, and the door panel connecting structure can also be directly installed on the door panel, but the connecting plate needs to be cut according to the width of the cabinet on both sides before installation, which is more troublesome.

The first adjustment plate 25 is embedded and fixed in the first connecting part 2. The outer edge of the first connecting part 2 corresponding to the first adjustment plate 25 is provided with a block to prevent it from falling. Similarly, the second connecting part 3 and the leaf connector 10 are fixed by screwing a screw along the back of the leaf connector 10 through the fixing hole 103 and the second adjustment plate 35; the outer edge of the second connecting part 3 corresponding to the second adjustment plate 35 is provided with a block to prevent it from falling.

[0036] A cabinet pull-out connection structure includes a sliding structure 6, a front end of the sliding structure 6 is provided with a reinforcement member 7 for connecting to a cabinet door, and a rear end of the sliding structure 6 is provided with a leaf connector 10; The sliding structures 6 are arranged in pairs on both sides of the cabinet, and the first connecting parts 2 and the second connecting parts 3 at both ends of the connecting plate body 1 are screwed and fixed to the leaf connector 10 by screws respectively.

[0037] Furthermore, in the above scheme, the leaf connector 10 is provided with a back sheet 101 that is in contact with the back of the first connecting part 2 and the second connecting part 3, and a top sheet 102 that supports the first connecting part and the second connecting part, and the back sheet 101 is provided with a plurality of fixing through holes 103.

[0038] The sliding structures 6 are arranged in pairs on both sides of the cabinet. The first connecting parts 2 and the second connecting parts 3 at both ends of the connecting plate body 1 are respectively screwed and fixed to the leaf connector 10 by screws. The reinforcing member 7 includes a bottom plate 71 and an adjustment plate 72. The bottom plate 71 and the adjustment plate 72 are connected as a whole through the assembly holes 9 provided on the bottom plate 71 and the adjustment plate 72 and the fastening adjustment member 8 connected to the assembly hole 9. Furthermore, in the above scheme, the adjustment plate 72 includes a vertically arranged fixed end and a horizontally arranged adjustment end, and the shaft connecting hole 91, the fixing screw hole 92 and the height adjustment slot hole 93 are horizontally arranged at the same height on the adjustment end. The shaft connecting hole 91 is arranged on the side of the adjustment plate 72 close to the fixed end, and the fixing screw hole 92 and the height adjustment hole are arranged on the other side of the adjustment plate 72 away from the shaft connecting hole 91.

[0039] Furthermore, in the above scheme, the assembly hole 9 includes an axis connection hole 91, at least one fixing screw hole 92, and a height adjustment slot 93. The bottom plate 71 and the adjustment plate 72 are both provided with corresponding positions and numbers of axis connection holes 91 and fixing screw holes 92. The height adjustment slot 93 only exists on the adjustment plate 72. The bottom plate 71 is provided with a fixing screw hole 92 at the position corresponding to the height adjustment slot 93. The fastening adjustment member 8 includes a fixed thread pair 81 and an eccentric thread pair 82, the fixed thread pair 81 is fixed to the shaft connecting hole 91 and the fixing screw hole 92, the eccentric thread pair 82 is fixed to the height adjustment slot 93; The assembly hole 9 includes an axis connection hole 91, no less than one vertical bar-shaped fixing screw hole 92 and one height adjustment slot 93. The base plate 71 and the adjustment plate 72 are both provided with axis connection holes 91 and fixing screw holes 92 corresponding in position and number. The axis connection hole 91, as the name implies, serves as the rotation axis of the relative inclination state between the base plate 71 and the adjustment plate 72. In addition, when the fixing screw hole 92 exists on the base plate 71, its shape is preferably circular, and when the fixing screw hole 92 exists on the adjustment plate 72, its shape is preferably vertical bar. This makes it easier to assemble and connect the bottom plate 71 and the adjustment plate 72 in a stable manner according to the position of the height adjustment slots 93. The fixing thread pair 81 can always pass through the vertical fixing screw holes 92 of the adjustment plate 72 and connect to the circular fixing screw holes 92 on the bottom plate 71, avoiding the problem of improper assembly.

The fixed thread pair 81 is fixed in the shaft connecting hole 91 and the fixing screw hole 92, and the eccentric thread pair 82 is fixed in the height adjustment slot hole 93. Since the eccentric thread pair 82 has the characteristic of changing its height with different rotation angles, and the shaft connecting hole 91 serves as the adjustment center, by adjusting the position of the rotation center of the eccentric thread pair 82 relative to the height adjustment slot hole 93, the base plate 71 can be fine-tuned in the pitch angle at a certain angle around the shaft connecting hole 91 as the center of the circle. After determining the specific angle, tightening the fixed thread pair 81 in the shaft connecting hole 91 and the fixing screw hole 92 can complete the fine-tuning of the installation state. The adjustment plate 72 includes a vertically arranged fixed end and a horizontally arranged adjustment end, and the shaft connecting hole 91, the fixing screw hole 92 and the height adjustment slot hole 93 are horizontally arranged at the same height on the adjustment end. The shaft connecting hole 91 is arranged on the side of the adjustment plate 72 close to the fixed end, and the fixing screw hole 92 and the height adjustment slot hole 93 are arranged on the other side of the adjustment plate 72 away from the shaft connecting hole 91. The assembly holes 9 on the adjustment end are linearly arranged at the same horizontal height, which is conducive to using the shaft connecting hole 91 as the rotation axis for adjusting the relative angle between the base plate 71 and the adjustment plate 72, and using the eccentric thread pair 82 to change the relative angle between the two, and the fixing screw hole 92 can connect the base plate 71 and the adjustment plate 72 at any angle, thereby completing fast, accurate and stable installation and positioning between the two.

[0040] In the technical solution of the overall pull-out structure of the cabinet of the present invention, the reinforcement 7 is connected and fixed to the cabinet door, the sliding structure 6 is connected and fixed to the inner walls on both sides of the cabinet, and the connecting plate main body 1 is connected to the rear ends of the sliding mechanism of the inner walls on both sides of the cabinet, wherein the connection angle between the reinforcement 7 and the cabinet door is adjusted by the fastening adjustment member 8, which uses fewer fasteners, reduces the cost of production and installation, and optimizes the configuration position of the fasteners. The connecting plate main body 1 can be independently telescopically adjusted according to the size of the cabinet without on-site cutting, and the requirements for assembly are reduced. The reinforcement 7, the sliding structure 6 and the connecting plate main body 1 form a modular installation structure, which is set as a whole. Without reducing the original installation strength effect, the efficiency in actual cabinet installation is improved to a certain extent, and due to the reduced assembly requirements and the simplification of the assembly parts structure, the workload of the assembler is also reduced, which makes reasonable simplification and improvement to the existing scheme.

[0041] The above description is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
