Although the hinge is small and inconspicuous, it is very important for interior doors and furniture and affects the use effect, so choose carefully when choosing. Spring hinges are mainly used in furniture installation. They can be closed automatically after opening, which is very convenient to use. However, it is inevitable that there will be problems during use, and new spring hinges need to be replaced. What are the types of spring hinges and how to install them? Let's take a look at them together.
Types of hinges
1. Ordinary hinge: used for cabinet doors, windows, doors, etc. The 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.
2. Pipe hinge: also called 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 adjusting screws, which can adjust the height and thickness of the board up and down, left and right. One of its features 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 degrees, 144 degrees, 165 degrees, etc. have corresponding hinges to match, so that various cabinet doors have corresponding extensions.
3. Door hinge: It is divided into ordinary type and bearing type. 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 they are beautiful in style, beautiful, affordable, and equipped with screws.
4. Bearing hinge (brass): Each hinge of the hinge is equipped with a one-way thrust ball bearing, the door switch is light and flexible, and is mostly used for heavy doors or special steel frame steel doors.
5. Inclined detachable hinge: This kind of hinge utilizes the inclined surface of the hinge and the weight of the door leaf to automatically close the door. Mainly suitable for lighter wooden doors or half doors such as toilets.
6. Cold storage door hinge: surface baking paint, large size made of steel plate, small size made of cast iron. Used on cold storage doors or heavy insulation doors.
The installation method of the spring hinge
Before installation, check whether the hinge matches the door and window frame and fan, check whether the hinge groove matches the height, width, and thickness of the hinge, and check whether the hinge and its connecting screws and fasteners are matched. When installing, ensure that the shafts of the hinges on the same leaf are on the same vertical line to prevent the doors and windows from springing up. Before installing the spring hinge, it is necessary to determine whether the door type is a flat door or a tongued door, the material, shape and installation direction of the door frame.
1. Insert a 4mm hexagonal key into the hole at one end, press firmly to the end, and open the hinge at the same time.
2. Install the hinges with screws into the hollowed grooves on the door leaf and door frame.
3. Close the door leaf, make the spring hinge in the closed state, insert the hexagonal key again, without pressing down, turn it clockwise, and hear the sound of the gear meshing four times, do not exceed four times ! If more than four times, because the spring has been twisted to the limit, the spring will be damaged and lose its elasticity when the door leaf is opened.
4. After the hinge is tightened, the opening angle cannot exceed 180 degrees.
5. If you want to loosen the hinge, just do the same as step 1.
Stainless steel hinge installation steps
1. First, choose the appropriate hinge types and specifications according to the door leaf, window leaf and frame to be installed. If the style does not match, the door and window cannot be installed properly. If you are not sure about the type and specifications, you can measure it according to the above introduction. The number of purchases is determined by the number of door or window sashes. Generally, two stainless steel hinges are required for a door and window.
2. Slot on the side of the door and window where the hinge needs to be installed. The depth of the groove should be the same as the thickness of the hinge. The corresponding position on the frame should also be grooved to keep the same depth.
3. Stand up the door panel or window sash and place it on the corresponding position on the frame, and then place the stainless steel hinge flat in the groove. The surface of the page board should be flush with the surface of the frame. Then fix it with screws. Do not tilt when installing the screw, otherwise it will be easily squeezed during use, which will shorten the service life.
4. After installing the screws, check the doors and windows and close them repeatedly to test whether they are smooth. If there is a sense of heaviness, adjust the hinge. Until the switch feels smooth.
