Description

Technical Field

[0001] The present invention relates to the technical field of hinges, and in particular to a hinge with adjustable spacing between rotating parts. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. It can be composed of movable components or foldable materials, and is widely used in furniture such as doors, windows, cabinets, and wardrobes. For example, ordinary hinges are often used for doors and windows; cabinet doors and wardrobe doors often use spring hinges, hydraulic buffer hinges, etc., which are classified by function: including one-stage force hinges, two-stage force hinges, hydraulic buffer hinges (damping hinges), touch self-opening hinges, etc. For example, damping hinges can provide a buffering function when the cabinet door is closed, reducing collision noise.

[0003] In traditional hinges, double needles press the plastic parts at the hinge cup, and the oil cylinder is set in the hinge arm body, connected to the stacked sheets through connecting parts, and the other end of the stacked sheets is connected to the hinge cup. This structure is relatively complicated, with high processing costs and is not easy to install. There is a plastic sheet at the hinge position, which is hinged through four holes. The spring in the hinge arm has no stress point, which is not convenient for positioning and has poor stability. The hinge wing base is assembled from loose parts, not integrally formed, and the stress surface of the base is weak, and the stability is not good enough. Therefore, a hinge with adjustable rotating part spacing is proposed. Summary of the invention

[0004] The present invention provides a hinge with adjustable spacing between rotating parts to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A hinge with adjustable spacing between rotating parts comprises a hinge mechanism, wherein the hinge mechanism comprises a cup head, a spike and a U-shaped needle, wherein the U-shaped needle penetrates the surface of the cup head and is connected to the spike; a buffer mechanism, wherein the buffer mechanism comprises a slider, an oil cylinder and four holes, wherein the slider is arranged on the surface of the four holes, and a slider cover is connected to the surface of the slider.

[0007] A further improvement of the technical solution of the present invention is that one end of the four holes is rotatably connected to the surface of the cup head through a U-shaped needle, and one end of the spike away from the cup head is rotatably connected to a hinge arm.

[0008] A further improvement of the technical solution of the present invention is that one end of the four holes away from the cup head is rotatably connected to one end of the hinge arm, an integrally formed base is provided at one end of the hinge arm, and a second adjustment hole is provided on the surface of the integrally formed base.

[0009] A further improvement of the technical solution of the present invention is that a reinforcing bottom plate is provided at the bottom of the one-piece molded base, and an adjusting screw is threadedly connected to the surface of the reinforcing bottom plate.

[0010] A further improvement of the technical solution of the present invention is that: the buffer mechanism further includes a cylinder sleeve, and the surface of the cylinder sleeve is fixedly connected to the surface of the cup head.

[0011] A further improvement of the technical solution of the present invention is that a buffer cylinder is arranged inside the cylinder sleeve, and one end of the buffer cylinder overlaps the surface of the sliding block.

[0012] A further improvement of the technical solution of the present invention is that: a mounting hole is provided at the upper end of the reinforcing bottom plate, and a first adjustment hole is provided at the middle of the reinforcing bottom plate.

[0013] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0014] The present invention provides a hinge with adjustable rotating part spacing, in which two grooves on the surface of four holes bulge inwards, and the inner convex point presses against the spring to play a positioning role, which is convenient for installation and improves the stability of the cabinet door. At the same time, it is fixed with only a single U-shaped nail. Compared with the conventional two U-shaped nails, the structure is simpler and the processing cost is lower. There is no plastic sheet in the cup head, and the cylinder is arranged on the outside of the cup head, which changes the original cylinder connection method, optimizes the connection structure, and improves the hinge quality. In addition, a single cylinder buffer or two cylinder buffers can be freely selected according to actual needs, and the adaptability is stronger. At the same time, the one-piece molded base is beautiful and practical. A multi-directional adjustable elliptical groove is arranged in the one-piece molded base, which can adjust the gap between the cabinet door and the cabinet body. After the installation distance is adjusted, it is fixed by screws, so that the installation effect is better, the overall structure of the hinge is optimized, convenient and practical, and the production process is reduced and the production cost is saved.
