A complete garage door usually consists of three parts: door panel, accessories and door opener. The neat accessories are also called garage door hardware accessories, mainly including balance system (wire rope + rope wheel + conduit + jacket + torsion spring), hinge (also called hinge), guide bracket (track pulley), etc.
Also known as hinge, it can be divided into middle hinge and end hinge (side hinge) according to the installation position. The middle hinge is connected with two adjacent door panels, so that it can rotate outward, and also has the function of supporting roller on the track.
According to different door panel structure, through the hinge is usually divided into: ordinary hinge and anti clamping hand hinge. Common leaves are divided into 1-12 kinds of shapes. The quality mainly affects the operation of the door: operation noise, operation resistance, service life and appearance.
To judge the level of general hinge and the method to prevent the height of the grip hinge: the hinge (hinge) is like a human's joint, with a certain degree of tightness and sensitivity. The larger the hinge hole, the tighter it can be, the smaller it can be hairpin.
It can be analyzed from the aspects of plate thickness, uniformity of zinc coating, standard anti-corrosion treatment, no obvious defects in appearance, hinge elasticity, hinge joint gap size, hairpin, looseness, etc. If galvanized sheet has no holes. Cracking and scum. The coating is too thick. Start from scratch. Chromic acid pollution. White rust and other defects.
2. Jinan garage door balance system
The spring force is used to balance the gravity of the door, so as to reduce the resistance and operation of the door and improve the reliability and safety of the system. The torsion spring is the most important part of the balance system. The torsion spring on the door is like the human heart, second only to the motor. A good set of springs is essential for the whole garage door.
An ideal condition for a well balanced garage door. After disassembling the door machine clutch, hold the door body by hand. After applying the force gently, the door body can move in the direction of the force. During the whole process of the door body operation, release the back door body to move up and down. The main factors affecting the balance effect are: first, the quality of spring; second, whether the selection of spring parameters is reasonable. The third is related hardware structure and manufacturing precision.
3. Guidance support framework
Guide support frame: refers to the combination of structural parts that guide the running track of the door leaf and support the weight of the door leaf, which is composed of guide rail, roller and various supports of guide rail. The key is tracking. The tracking thickness is 1.5mm, 2.0mm, 1.8mm, 2.5mm and even 1.2mm. Although the price is reduced, there is a safety risk in thin, which will greatly reduce the service life of the door. It is recommended not to use.
