Multifunctional cabinet door hinge

Abstract

The invention discloses a multifunctional cabinet door hinge which comprises a main rotating pull rod, a main rotating connecting rod, a transmission connecting rod, a transmission pull rod, a tension spring, an inner frame base and an outer door base. An adjustable adjusting support is arranged on the inner frame base. The adjusting support is provided with a spring connecting hole. A first spring hook is arranged on the spring connecting hole. One end of the main rotating pull rod and one end of the main rotating connecting rod are connected with the adjusting support through shafts. The other end of the main rotating pull rod is connected with the transmission connecting rod, and the other end of the main rotating connecting rod is connected with the transmission pull rod. A first connecting hole is formed in the middle of the main rotating connecting rod. A second connecting hole is formed in the middle of the transmission connecting rod. The multifunctional cabinet door hinge is reasonable in structure, accurate, fast and easy to assemble, high in practicability and free of bad phenomena of noise, loosening, deformation, disengagement and the like during repeated starting.

Description

technical field [0001] The invention relates to the field of hardware components, in particular to an intelligent multifunctional cabinet door hinge. Background technique [0002] At present, the traditional hinge is composed of connecting rods, pull rods, "pipe" racks, inner bases, outer door hinge cup seats and tension springs. Due to unreasonable structure and improper combination, it directly affects the use function of the hinge, and it is easy to appear after long-term use. In the case of failure to operate normally, the main focus is on the following points: [0003] 1. Each component is easily damaged, the gap between the door gap is too large, the opening and closing swings, the offset sags, the service life is short, and it needs to be replaced frequently; [0004] 2. When installing, it is necessary to drill holes in the door in advance. The installation positioning is limited, and it cannot be installed at will. [0005] 3. When installing the full cover, half ...

Problems solved by technology

[0002] At present, the traditional hinge is composed of connecting rods, pull rods, "pipe" racks, inner bases, outer door hinge cup seats and tension springs. Due to unreasonable structure and improper combination, it directly affects the use function of the hinge, and it is easy to appear after long-term use. In the case of failure to operate normally, the main focus is on the following points:

[0003] 1. Each component is easily damaged, the gap between the door gap is too large, the opening and closing swings, the offset sags, the service life is short, and it needs to be replaced frequently;

[0004] 2. When installing, it is necessary to drill holes in the door in advance. The installation positioning is limited, and it cannot be installed at will.

[0005] 3. When installing the full cover, half cover, and inner cover, it needs three models of straight bending, medium bending, and large bending to complete. The assembly is not simple, fast, easy, and inaccurate. The structure is not ideal and the practicability is deviated;

[0006] 4. The "pipe" frame is long, its bearing capacity is low, the working distance of the connecting rod and tie rod is short, the opening angle is small, it is inconvenient to use, and there are bad phenomena such as noise, looseness, deformation, and falling off when opening and closing
