A Noise Reduction Hardware Hinge Based on Graphite Lubrication

Abstract

The invention provides a graphite-lubricated noise-reducing hardware hinge, which relates to the technical field of hardware accessories. The graphite-lubricated noise-reducing hardware hinge includes a left-turning plate and a right-turning plate, a collar is fixedly installed between the left-turning plate and the right-turning plate, and a core rod runs through the interior of the collar, so The top of the core rod is fixedly installed with a material storage barrel, the bottom of the core rod is threadedly connected with a nut, the inside of the core rod is provided with a pipe, and a spacer is set between the outer rings of the core rod. Guide rail grooves are provided in the insides of the left turning plate and the right turning plate. The noise-reducing metal hinge based on graphite lubrication can effectively lubricate between the rotating plate and the core rod for a long time, reduce the wear of the collar and the core rod, and avoid the noise generated when the hinge rotates, and the rotating plate The fixed point of the hinge can be adjusted, which avoids drilling at unsuitable points on the threshold or door body, and improves the practicability of the hinge.

Description

technical field [0001] The invention relates to the technical field of hardware accessories, in particular to a noise-reducing hardware hinge based on graphite lubrication. Background technique [0002] Hinge, also known as hinge, officially called hinge, is a common accessory in hardware stores. It is usually a two-fold design, which is formed by rotating and connecting two folding plates. It is widely used in cabinets, doors, windows, etc. Installation, materials are iron, copper and stainless steel and so on. [0003] The left and right folded plates of the hinge are connected in series through the mandrel, and the folded plates and the mandrel are in contact with each other. Therefore, during the rotation of the folded plates, the folded plates and the mandrel will rub against each other. When the leaf is manufactured, lubricating oil will be applied to the periphery of the mandrel, but when the lubricating oil volatilizes or is exhausted, the wear of the folding plate ...

Problems solved by technology

[0003] The left and right folded plates of the hinge are connected in series through the mandrel, and the folded plates and the mandrel are in contact with each other. Therefore, during the rotation of the folded plates, the folded plates and the mandrel will rub against each other. When the leaf is manufactured, lubricating oil will be applied to the periphery of the mandrel, but when the lubricating oil volatilizes or is exhausted, the wear of the folding plate and the mandrel will be aggravated, and noise will be generated during the rotation process, and the traditional folding The installation counterbore of the page is fixed and cannot be adjusted, and it is impossible to avoid the threshold or the point on the door body that is not suitable for drilling, which reduces the practicability
