Type of hinge
• Ordinary hinges
For cabinet doors, windows, doors, etc. Materials are iron, copper, and stainless steel. The disadvantage of ordinary hinges is that they do not have the function of spring hinges. After the hinges are installed, various bumpers must be installed, otherwise, the wind will blow the door panels.
• Pipe hinges
Also called a spring hinge. Mainly used for the connection of furniture door panels, it generally requires a panel thickness of 16-20 mm. The materials are galvanized iron and zinc alloy. The spring hinge is equipped with an adjusting screw, which can adjust the height and thickness of the plate up and down, left and right. One of its characteristics is that it can match the opening angle of the cabinet door according to the space. In addition to the general 90-degree angle, 127-degree, 144-degree, 165-degree, etc. have corresponding hinges to match, so that various cabinet doors have corresponding extensions.
• Door hinges
It is divided into ordinary type and bearing type, and the ordinary type has been mentioned before. The bearing type can be divided into copper and stainless steel in terms of material. Judging from the current consumption situation, more copper-bearing hinges are used because of their beautiful and bright style, moderate price, and equipped with screws.
• Other hinges
There are glass hinges, countertop hinges, and flap hinges. The glass hinge is used to install the frameless glass cabinet door, and the thickness of the glass is required to be no more than 5-6mm.
Hinge Invention
Whether it is a magnificent star-rated hotel or a common residential building in modern architecture, it is difficult for people to see wooden "hushu". The doors and windows of modern buildings mostly use metal hinges. The door shaft hinge produced by modernization has replaced the ancient "hukou". The ancient invention of "hushu" still remains on some old doors and windows of some ancient buildings and rural residential buildings in Guanzhong.
Friends who have carefully observed the bronze chariots and horses of the Qinling Mausoleum may remember the hinges and hinges at the junction of the No. 2 bronze carriage door and the compartment, which are completely similar to modern building doors and window hinges in terms of shape and structure. It marks that our ancestors first invented and used hinges as early as 2200 years ago, and we also found that the scope of hinges used by Qin people is by no means limited to copper chariots and horses. Near the chariots in Pit No. 2 and Pit No. 1 of the Terracotta Warriors, archaeologists discovered an equally considerable number of bronze hinges. Facts have proved that the door shaft hinge is by no means an "imported product", but an "invention patent" belonging to the Qin people.
Installation points
The installation of hinges is very particular, and the 6 key points to pay attention to are:
(1) Before installation, check whether the hinges match the door and window frames and leaves.
(2) Check whether the hinge groove matches the height, width, and thickness of the hinge.
(3) It should be checked whether the hinges are compatible with the screws and fasteners connecting them.
(4) The connection method of the hinge should match the material of the frame and leaf. For example, the hinge used for the steel frame wooden door, the side connected to the steel frame is welded, and the side connected to the wooden door leaf is fixed with wood screws.
(5) When the two leaf plates of the hinge are asymmetrical, it should be identified which leaf plate should be connected to the fan, which leaf plate should be connected to the door and window frame, and the side connected to the three sections of the shaft should be connected to the frame. Fixed, the side connected to the two sections of the shaft should be fixed with the doors and windows.
(6) When installing, it should be ensured that the axes of the hinges on the same leaf are on the same vertical line, so as to prevent the door and window leaves from springing up.
