Background technology:
Current door opening machine of garage is on the market roughly divided into two kinds: draw high formula and roller shutter type.Drawing high formula door lifter is contained in after garage door by door lifter, the transmission device such as chain, belt of driven by engine on door lifter on it thus control the switch of garage door, but this door application has certain defect, the space taken as this door lifter and corresponding door thereof is larger, and component on it are more, easy break-down; The door lifter of roller shutter type is then be contained on door-hinge by door lifter, the rotation of the axle on door lifter thus drive garage door to roll up on door-hinge, the door-opening mode of this door lifter can reduce the height of door opening, and in addition, the mounting means of this door lifter makes its maintenance cumbersome.
Summary of the invention:
For above-mentioned deficiency, even if the object of the invention is that providing a kind of structure door that is simple, that be unlocked to install makes simple and do not have the door lifter that electricity still can open Door by Hand.
The present invention is achieved through the following technical solutions.
A kind of door opening machine of garage, comprise main frame and annex, described main frame is by motor, worm screw, worm gear, gear shaft and gear composition, described annex comprises pull bar, sliding sleeve and connecting rod, described worm screw is arranged on the output shaft of motor, described worm and worm wheel coordinate, a travelling gear described worm-wheel shaft is equipped with, two groups of gear shafts are equipped with in direction parallel with worm-wheel shaft on described main frame, a driven gear and a travelling gear described first group of gear shaft be equipped with, described second group of gear shaft is equipped with a driven gear, travelling gear on described worm-wheel shaft coordinates with the driven gear on first group of gear shaft, travelling gear on first group of gear shaft coordinates with the driven gear on second group of gear shaft, described worm-wheel shaft is equipped with arming mechanism, described second group of gear shaft is connected with position-limit mechanism, sliding sleeve one end is fixed on the other end on wall and is connected with pull bar, pull bar is connected with second group of gear shaft by connecting rod.
Preferred as this technical scheme, the diameter of the travelling gear on described worm-wheel shaft is less than the diameter of driven gear on first group of gear shaft.
Preferred as this technical scheme, the diameter of the travelling gear on described first group of gear shaft is less than the diameter of the driven gear on second group of gear shaft.
Beneficial effect: door lifter structure of the present invention is simple, easy to operate, is also convenient to maintenance process simulation simultaneously, and the installation of the door be unlocked makes also fairly simple, and cost is reduced; In addition, this door lifter is provided with kickoff mechanism, even if also can open Door by Hand when not having electric, and the installation of position-limit mechanism also facilitates the start or stop position of adjustment doors.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of main frame.
Fig. 2 is the front view of host housing.
Fig. 3 is schematic diagram when closing.
Fig. 4 be door half-open time schematic diagram.
Schematic diagram when Fig. 5 is standard-sized sheet.
Detailed description of the invention:
Below in conjunction with accompanying drawing and embodiment, the invention will be further described, but the protection domain of invention not limit by embodiment.
As shown in Fig. 1, Fig. 2, a kind of door opening machine of garage, comprises main frame and annex, and main frame is made up of motor 1, worm screw 3, worm gear 4, gear shaft and gear; Metal shell is equipped with main frame, in order to fixing and that protection is inner component; Motor 1 is fixed on the shell of main frame by hexagon socket head cap screw and hex nut, it is for whole mechanism provides power, the output shaft 2 of motor 1 is equipped with worm screw 3, a worm-wheel shaft 5 is equipped with in the direction vertical with worm screw 3, worm-wheel shaft 5 is provided with the travelling gear of the worm gear 4 and minor diameter engaged with worm screw 3; In addition, two groups of gear shafts direction parallel with worm-wheel shaft on main frame are equipped with, on first group of gear shaft 6, cover has a driven gear and a travelling gear, the diameter of driven gear is 2 times of travelling gear diameter, second group of gear shaft 7 connects a driven gear and axle sleeve 8 by keyway, axle sleeve 8 and driven gear screw, bearing pin are fixed, and the diameter of this driven gear is greater than the diameter of the driven gear on first group of gear shaft 6.The position relationship of motor 1, worm-wheel shaft 5, first group of gear shaft 6 and second group of gear shaft 7: the worm screw 3 on motor 1 engages with the worm gear 4 on worm-wheel shaft 5, travelling gear on worm-wheel shaft 5 coordinates with the driven gear on first group of gear shaft 6, and the travelling gear on first group of gear shaft 6 engages with the driven gear on second group of gear shaft 7.Axle sleeve 8 connects a limit switch 9, in order to the position of the switch of adjustment doors.Worm-wheel shaft 5 is provided with flat key in keyway, worm-wheel shaft 5 axially have screw hole, be provided with push rod 10 in screw hole, push rod 10 goes directly flat key, and the other end of flat key connects a spring, composition kickoff mechanism.
See Fig. 4, annex comprises pull bar 11, sliding sleeve 12 and connecting rod 13, and pull bar 11 is connected with second group of gear shaft 7 by connecting rod 13, and described sliding sleeve 12 one end is connected with pull bar 11, and the other end is fixing on the wall.
Door lifter is fixed on the back side of door, fixes more firm to make door lifter, and install leg at the two ends of connecting rod 13, leg is fixed on door; The both sides of door install a pull bar additional, and one end of pull bar is hinged on doorframe, and the other end is hinged on the side of door.
During work, motor 1 drives the worm screw 3 be arranged on motor output shaft 2 to rotate, worm screw 3 coordinates with worm gear 4 and drives worm-wheel shaft 5 to rotate, the rotation of worm-wheel shaft 5 drives the travelling gear on it to move, travelling gear coordinates with the driven gear on first group of gear shaft 6, thus drive the travelling gear on first group of gear shaft 6 and gear shaft to rotate, this travelling gear coordinates drive second group of gear shaft 7 to rotate with the driven gear on second group of gear shaft 7, like this by 3 grades of decelerations, make the rotating speed step-down of second group of gear shaft 7, moment increases, reach the condition that door can be driven to open.See Fig. 3, Fig. 4, Fig. 5, when door lifter half-twist, under the reaction of annex, a body is upwards drawn high door is opened, at this moment, limit switch contact encountered by the axle sleeve 8 that second group of gear shaft is installed, and plays spacing effect; Door lifter opposite spin 90 °, plays the object of closing the door.In time not having electric, promote the push rod 10 on arming mechanism, worm gear 4 and worm screw 3 are freed, can open Door by Hand.
