Description

Technical Field

[0001] This utility model relates to the field of cabinet flip-up door technology, and in particular to a hidden flip-up door pneumatic support hinge structure. Background Technology

[0002] The importance and wide range of applications of lift-up doors in modern furniture design, such as cabinets, wardrobes, and display cases, highlight the growing demand from consumers for both aesthetics and practicality in their homes. Traditional hinges are finding it increasingly difficult to meet market needs, particularly in terms of space utilization, aesthetic appeal, and durability.

[0003] Currently, in some furniture cabinets, the cabinet doors need to be opened by flipping up and closed by flipping down. Traditional surface-mounted hinges can connect and fix the cabinet doors to the cabinet body after installation, allowing them to be opened by flipping up and closed by flipping down. However, the exposed parts will detract from the overall aesthetics of the furniture. This defect is particularly noticeable for furniture that pursues a minimalist style and modern design. In addition, the clamped cabinet doors still need to be opened and closed manually, which is quite troublesome. Therefore, a hidden pneumatic support hinge structure for flip-up doors is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that, in the existing technology, the exposed part of the traditional surface-mounted hinges will destroy the overall aesthetics of the furniture after installation, especially for furniture that pursues a minimalist style and modern design. This defect is particularly obvious. In addition, the cabinet door with clamps still needs to be opened and closed manually, which is quite troublesome. Therefore, a hidden pneumatic support hinge structure for the upward-opening door is proposed.

A hinge mounting plate is fixedly connected to the top end of the hinge connector, and a hinge support shaft is provided at the bottom of the hinge connector. A top mounting plate is provided at the top of the pneumatic telescopic rod, and a bottom mounting plate is provided at the bottom of the pneumatic telescopic rod.

[0007] Preferably, the hinge mounting plate has symmetrically formed first holes, an L-shaped hinge upper connecting plate is provided on one side of the hinge mounting plate, a second hole coaxially arranged with the first hole is symmetrically formed on the side of the hinge upper connecting plate near the hinge mounting plate, and a third hole is symmetrically formed on the top of the hinge upper connecting plate.

[0008] Preferably, a fixing tube is connected to the bottom end of the hinge connector, the hinge support shaft is inserted into the fixing tube, and a lower hinge connecting plate is fixedly connected to the outer wall of the fixing tube on both sides of the fixing tube. A fourth hole is provided on the lower hinge connecting plate.

[0009] Preferably, a top connecting block is fixedly connected to the top of the pneumatic telescopic rod, a connecting shaft is fixedly connected to the top connecting block, a top connecting rod is fixedly connected to the bottom of the top mounting plate, the connecting shaft is rotatably connected to the top connecting rod, and a fifth hole is symmetrically opened on the top of the top mounting plate.

[0010] Preferably, a bottom connecting block is fixedly connected to one bottom end of the pneumatic telescopic rod, and a bottom connecting rod is fixedly connected to one side of the bottom mounting plate, with the bottom connecting rod rotatably connected to the bottom connecting block.

[0011] Preferably, the bottom connecting rod has a T-shaped cross-section, and the bottom mounting plate has multiple sixth holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When using this device, install one end of the hinge connector inside the cabinet and connect the other end of the hinge connector to the cabinet door. This concealed hinge connector design greatly enhances the overall aesthetics and sophistication of the furniture by hiding the hinge connector inside the furniture cabinet.

[0014] 2. When using this equipment, install one end of the pneumatic telescopic rod inside the cabinet, and then connect the other end of the pneumatic telescopic rod to the cabinet door. By controlling the extension and retraction of the pneumatic telescopic rod, you can control the cabinet door to open upwards and close downwards, eliminating the need to manually open or close the cabinet door, which is more convenient.
