Abstract
The present invention relates to a door opening machine device with a sliding door, which comprises a body which is arranged at the lower side edge of a door body and is provided with a rotary wheel. The present invention is characterized in that a worm gear and worm driving mechanism is arranged in a driving device which is arranged on the body and is used for driving the rotary wheel to rotate, a gear is arranged on a rotary wheel body, and a rack which is engaged with the gear is arranged on the ground where the door body is closed to stop. The device has the obvious advantage of firm self locking when the door is closed to stop.
Description
Technical field
The present invention relates to a kind of door lifter device of vertical hinged door.
Background technology
Existing vertical hinged door door lifter adopts the switching of hydraulic pressure or spiral expansion link mechanism drive door body usually, the shortcoming of existence: the one, and rod member and door body are stressed greatly, and mechanism is fragile, the 2nd, transmission efficiency is low, and the 3rd, inconvenience is installed, the 4th, volume is big, structure is not compact, and influences outward appearance.In addition, the door body is closed when putting in place, all need realize the locking of a body usually by means of devices such as latch or bolts, so obvious operation inconvenience.
Summary of the invention
The door lifter device of the firm vertical hinged door of self-locking when the object of the present invention is to provide a kind of door-closing in-place.
The present invention constitutes like this, and it comprises the body with runner of the lower lip that is installed on a body, it is characterized in that: be provided with Worm and worm-wheel gearing in the transmission device in order to the running of driving runner that is provided with on (1) body; (2) web is provided with gear; (3) the door body is closed the ground that puts in place and is provided with the tooth bar that is meshed in order to gear.
During this device busy, drive runner by worm and gear and rotate, open and close thereby drive the door body.When the door body is closed when putting in place, if door will be promoted, because runner can not turn round by reverse drive worm and gear device, thereby runner is forced to stop operating, at this moment, owing to be arranged on the engagement of the rack-and-pinion on the web, prevented that the slip of runner by on the ground from driving a body and rotating, thereby realized the reliable self-locking of door body.
Than the door lifter device of existing vertical hinged door, the present invention not only self-locking is firm, and compact conformation, the transmission efficiency height, and it is convenient to manipulate.
Description of drawings
Fig. 1 is an embodiment of the invention organigram.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The present invention constitutes like this, and it comprises the body with runner 12 of the lower lip that is installed on a body, it is characterized in that: be provided with Worm and worm-wheel gearing 3 in the transmission device in order to the running of driving runner that is provided with on (1) body; (2) web is provided with gear 4; (3) the door body is closed the ground 5 that puts in place and is provided with tooth bar 6 in order to be meshed with gear.
Above-mentioned tooth bar is provided with one and turns 7, and the body of runner respective side portion is provided with a body and closes and can fasten the gib head 8 that turns head when putting in place.
Above-mentioned transmission device can by motor 9, Worm and worm-wheel gearing and be connected in worm wheel shaft 10 and runner rotating shaft 11 between sprocket wheel or gear drive 12 form.
During work, the running of motor-driven worm and gear, and by the rotation of chain wheel driving mechanism drive runner, thereby drive a door body switch.When door-closing in-place, if wanting reverse pushes door open, because runner can not turn round by reverse drive worm and gear device, thereby runner is forced to stop operating, at this moment, on the one hand owing to be arranged on the engagement of the rack-and-pinion on the web, prevented that the slip of runner by on the ground from driving a body and rotating, make the door body reversely not to be open, thereby realized the firm locking in the horizontal direction of door body; On the other hand, because a door body is closed when putting in place, the gib head that is arranged on the body of runner respective side portion has fastened the head that turns that is positioned at the tooth bar place, makes that a door body can not upwards be lifted, thereby has realized the firm locking in vertical direction of door body.
For fear of making worm and gear shut down because of having a power failure or breaking down, cause a body not move, in the conical cavity 13 of runner rotating shaft one end, be provided with a taper body 14, the wore long screwed hole at a bolt 15 and runner rotating shaft middle part in its duct, middle part of this taper body links, when the user unclamps bolt with the instrument of random arrangement, and a promotion door body is opened with runner, when closing, the axial thrust load that the runner conical cavity acts on the reaction force on the taper body will make the taper body break away from conical cavity, so, the taper body promptly is separated from conical cavity, make runner break away from the constraint of chain wheel driving mechanism, door can be opened or closed with hand propelled door body so that the user needs only.
Advance on broken terrain in order to help driving the door body, body with runner is installed in and is positioned on the location-plate of body lower lip 16, body is provided with the slide rail body 18 that can slide up and down in the chute 17 of location-plate, be provided with extension spring assembly 19 between slide rail body and the chute, the lower end of extension spring is connected on the following side of location-plate, and the upper end is connected on the upper lateral part of body.When the door body is run into ground protrusion in moving process, protrusion is for the reaction force meeting jack-up castor of castor, body is moved upward by the chute of its slide rail body along location-plate, so that clear the jumps, after clearing the jumps, body is replied under the effect of the recovery elastic force of extension spring again and is put in place, thereby can remain castor and advance smoothly on the ground.
In addition, above-mentioned extension spring upper end is adjusted bolt 20 through elastic force and is connected on the upper lateral part of body, and before the use, the user can adjust the pretension that bolt is set extension spring by rotation elastic force, thereby adjusts the pressure size of body to ground.
The present invention is not only novel, compact conformation, and transmission efficiency height, reliable operation, and its popularizing application prospect is very considerable.
