This two folding door have open and close efficient, stability good, advantages such as long service life are applicable to places such as bureau of fire protection.
Description
Technical field
The utility model relates to a kind of door and window, specifically refers to a kind of improvement two folding door being mainly used in the places such as garage.
Background technology
At present, warehouse, garage and other public place start to adopt folding door to replace traditional vertical hinged door gradually.Due to folding door have easy for installation, open and close take up room little, cost is low and the advantage such as attractive in appearance.Such as, but general folding door keying speed is comparatively slow, stability is not fine, cannot adapt to the needs in Some features place: fire department and large-scale garage etc.
Utility model content
The purpose of this utility model is that good stability, improvement two folding door of long service life, this improvement two folding door is mainly applicable to Fire Department and police station in order to provide a kind of keying speed fast.Such as: Fire Department, be seize every minute and second when needs go out car, therefore, speed and the stability of the unlatching of its gate, fire house are just particularly important.If gate opening speed is too slow, or regularly to break down, so citizen's property and life will lose guarantee.
In order to achieve the above object, the utility model provides following scheme: a kind of improvement two folding doors, comprise upper folding door described in folding door, lower folding door, support column and be provided with slide-bar I, described lower folding door is provided with slide-bar II, the upper end of described support column is provided with driving shaft, the inner side of described support column is provided with door track and connecting portion I, and the inside of described support column is provided with motor rail, and the rear side of described support column is provided with counter weight device and variable-frequency motor;
The two ends of described slide-bar I and slide-bar II are all installed in door track;
Be provided with gear train, conveyer belt in described motor rail, described conveyer belt is provided with auxiliary cam device and truckle, and described gear train is connected with variable-frequency motor;
Described counter weight device comprise be installed on support column top assembly pulley, be installed on balance weight body below assembly pulley and counterweight pulley;
On rear side of described upper folding door, position on the upper side is provided with connecting portion II, and described connecting portion I and connecting portion II is flexibly connected by chain band.
Further optimization, the bottom of described upper folding door and the top of lower folding door are connected through the hinge.
Further optimization, be also provided with the guide rod of parallel distribution inside described support column.
The beneficial effects of the utility model: because upper folding door and lower folding door are all provided with slide-bar, make the keying speed of two folding doors faster, also more stable; The setting of counter weight device simultaneously further increases the stability that two folding doors open and close, thus reduces the probability of two folding door faults, is delayed the application life of two folding doors.
