Problems solved by technology

[0003] The door structure of the current telescopic door has the following disadvantages: 1), because there are many chutes, the running resistance is relatively large; 2), the existing telescopic door will be broken and deformed when the chute is not smooth etc., the structure is unreasonable; 3), because it is a parallelogram hinged structure, the stability is poor; 4), after so many years of market precipitation, consumers have experienced market aesthetic fatigue for telescopic doors with parallelogram hinged structure

Abstract

The invention relates to an extension door, in particular to an extension door with good stability, small running resistance, environmental protection and energy saving. The extension door comprises a door body, a principal axis among door body and a lantern ring arranged on the principal axis and capable of up and down slipping, wherein, the principal axis is nested equipped with a six points balance device used for balancing the stress effect among neighboring door bodies, both front and rear ends symmetry axis of the lantern ring are equipped with a balance supporting bar used for connecting neighboring door bodies, the balance supporting bar is axially connected with the beam midpoint of the door body, the balance supporting bar is capable of rotating along up and down directions around the beam of the door body, balance link devices are symmetrically arranged on the left and right sides along the extension door moving direction of the lantern ring, the balance link devices are respectively connected with the two neighboring door bodies and the balance link devices can rotate around the fixed point of the door body along left and right direction and up and down direction. The beneficial effects of the extension door are of strong intensity, firm, small resistance, small required power, environmental protection and energy saving, no friction transmission, more reasonable structure, electric motor required small power and lowering cost.

Description

technical field [0001] The invention relates to a telescopic door, in particular to a telescopic door with good stability, low running resistance, environmental protection and energy saving. Background technique [0002] Existing telescopic door is mainly made of door body, driver, control system. The door body is made of high-quality stainless steel and aluminum alloy special profiles, and is hinged by the principle of parallelogram, flexible and flexible. The driver is driven by a special motor, the worm gear is decelerated, and there is no manual clutch. It can be opened and closed manually when the power is off. The control system has a control panel and a button switch. The telescopic door is a telescopic shed lattice type, which has the characteristics of stable opening and closing, see-through door body, and small space occupation after opening. The telescopic door is suitable for the courtyard wall doors of industrial and mining enterprises, government institutions...
