Abstract

The utility model provides a folding door, which has the advantages of large processing amplitude of length and width, strong fastness, convenient operation and automatic rise and fall. The utility model is mainly composed of a plurality of guard plates formed by the connection of door locks, control switches, door frames, connection pieces and folding mechanisms, a guard plate storage groove, a speed reduction mechanism, a motor and an electric appliance box, wherein racks are processed on both ends of the guard plate, and the racks and gears installed on both ends of a gear shaft are meshed. After the motor is started, the gears drive the guard plates to move along grooved rails on both sides in a reciprocating way; when the guard plates cause the storage groove to rise and fall, one side rises along the grooved rail, and the other end is naturally stored on the bottom of the storage groove under the action of the folding mechanism.

Description

The automatic lifting folding door

The utility model relates to that a kind of simple in structure, fastness is strong, the backplate wide cut is unrestricted, but the protective door of automatic lifting.

At present, at applied protective doors in place such as bank, school, garage, hangar, car and boat mostly is with timber or metal manually-operated single page backplate or metal rolling door, telescopic paling form door, these exist take up room big, fastness is poor, efficient is low, the length and width amplitude of backplate is restricted and shortcoming that can not automatic lifting.

The purpose of this utility model is to provide that a kind of to be processed into the length and width amplitude big, and fastness is strong, and is easy to operate, but the protection folding door of automatic lifting.

The purpose of this utility model is to realize like this, it is by door lock (1), gauge tap (2), doorframe (3), plate (5) and amount to a plurality of backplates (4) that mechanism (8) is linked together, backplate accumulator tank (11), reducing gear (12), motor (13), electric appliance box (14) is formed, tooth bar (6) is processed at the two ends of backplate (4), tooth bar (6) and gear (9) engagement that is installed in gear shaft (10) two ends, gear (9) is stirred tooth bar (6), driving backplate (4) moves back and forth along both sides grooved rail (7), the axle (15) that protrudes backplate 4 edges is housed on the both sides backplate (4) of plate (5), the other end of axle (15) is equipped with axillare (16), bearing (17) is fixed on the axillare (15), between backplate (4) and axillare (16), spring (18) is housed, one end of spring (18) is fixed on the axillare (16), and the other end is spacing to it by pin (19).

The utility model compared with prior art has the following advantages:

It is big to be processed into the length and width amplitude, and fastness is strong, easy and simple to handle, efficient height, but the folding door of automatic lifting.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a lateral view of the present utility model;

Fig. 3 amounts to the sectional view of mechanism for the utility model;

Fig. 4 amounts to the vertical view of mechanism for the utility model.

In the accompanying drawing: 1 door lock, 2 gauge taps, 3 doorframes, 4 backplates, 5 plates, 6 tooth bars, 7 grooved rails, 8 are amounted to mechanism, 9 gears, 10 gear shafts, 11 accumulator tanks, 12 reducing gears, 13 motors, 14 electric appliance boxes, 15,16 axillares, 17 bearings, 18 springs, 19 pins

When needs start folding door, press gauge tap, starter motor rotates by reducing gear driven gear axle.The tooth bar engagement at the gear at gear shaft two ends and backplate two ends drives the grooved rail reciprocating motion of backplate along both sides, and when backplate rose to accumulator tank, an edge grooved rail rose, and the other end is stored in the bottom of accumulator tank naturally under the effect of amounting to mechanism.

Claims

1, a kind of automatic lifting folding door, mainly by door lock (1), gauge tap (2), doorframe (3), plate (5) and amount to a plurality of backplates (4) that mechanism (8) is linked together, backplate accumulator tank (11), reducing gear (12), motor (13), electric appliance box (14) is formed, it is characterized in that: tooth bar (6) is processed at the two ends of backplate (4), tooth bar (6) and gear (9) engagement that is installed in gear shaft (10) two ends, the axle (15) that protrudes backplate (4) edge is housed on the both sides backplate (4) of plate (5), the other end of axle (15) is equipped with axillare (16), bearing (17) is fixed on the axillare (15), between backplate (4) and axillare (16), spring (18) is housed, one end of spring (18) is fixed on axillare (16), and the other end is spacing to it by pin (19).
