Abstract

The utility model relates to a door opening machine for a garage, which meshes with a worm shaft in a motor and a worm wheel sleeved on a hollow pipe shaft for power output; wherein, the hollow pipe shaft is cooperated with a driving shaft. A torsional spring shaft which is sleeved with a torsional spring is coaxially connected with the driving shaft through a hoop, and ropes which drive a door plate to move along a rail are arranged on winding wheels at the two ends of the torsional spring shaft. The driving shaft is axially and orderly provided with a fixed embedding sleeve, a clutch component, a replacement spring, a clutch fixing sleeve and a bull gear; wherein, a manual rope is fixed and connected with the end cover of a motor; moreover, the other end of an adjusting nut positioned in a limiting screw rod can cause the motor to pull a hinge pin with a replacement spring to axially move. The utility model has the advantages of no noise operation, saving space, perfect security and practicability as well as safety and reliability; besides, the door opening machine is useful by use of a battery, thereby being applicable to the low space with two beams and the environment frequently cut power.

Description

The garage door door lifter

Technical field the utility model relates to a kind of mechanical closure, especially a kind of garage door door lifter that uses in the garage that is applicable to.

The present widely used garage door door lifter of background technology adopts the kinds of drive such as chain, belt or leading screw, so there is the big problem of noise in the use; As the situation of outage occurs in the garage door switching process, then motor can not be with door body locking; Can not realize that simultaneously manual operation pins the door body at an arbitrary position.Also there is the problem that mounting condition is had relatively high expectations in addition.

The summary of the invention the purpose of this utility model provides a kind of garage door door lifter that drives guide rail that do not have.

For achieving the above object, the utility model garage door door lifter comprises motor, track, transmission device, be the turbine engagement on the scroll bar axle in the motor and the hollow tubular axis that is socketed in motor output, hollow tubular axis cooperates with driving shaft, the torsion axis that is socketed with torsion spring is connected by anchor ear and driving shaft are coaxial, and the rope that the drive door-plate moves along track is arranged on the reel at torsion axis two ends.

After adopting said structure, under the effect of scroll bar axle rotary power, the rotary torsion that turbine and hollow tubular axis rotate generation synchronously is passed to driving shaft in motor; Because torsion axis reaches torsion axis with the coaxial power that is connected of driving shaft through driving shaft, torsion axis clockwise or be rotated counterclockwise and promote or discharge rope on the reel drives door-plate along the track lifting, is implemented in switch garage door under the condition of not having the driving guide rail.

As further improvement of the utility model, axially be provided with fixedly embedding facing, clutch component, clutch fixed cover, gear wheel successively along driving shaft; Between described clutch component and clutch fixed cover, be socketed with return spring, and shipper rope and electric motor end cap are affixed; It is interior and parallel with driving shaft that the two ends of spacing screw rod are arranged on shell end cover, is positioned at the pinion and the gear wheel engagement of spacing screw rod one end, and the adjustment nut is positioned at the other end of spacing screw rod and the motor that has return spring is pulled pin and moves axially.Adopt this structure when closing garage door, to adjust the nut pushing motor and pull pin and make the motor afterbody sagging, push down a body external force can't be opened the door body, realize anti-theft feature.The motor afterbody lifts door-plate and rises along track when opening garage door.The operator running rope makes the clutch sliding sleeve break away from fixedly embedding facing, but hand switch garage door at this moment.

The utility model has the advantages that: compare guide rail type of drive such as the T-shape that omitted the top, garage or " C " type track with existing garage door door lifter; So noiselessness in using; Because power spreads out of through the turbine worm mechanism of motor, can realize the optional position self-locking, and is safe and reliable; Because the sagging body of pushing down of motor afterbody in the time of in off position uses external force the door body can't be lifted; Play the antitheft effect of machinery; As sudden power in lifting process, then can the door body be opened or be closed by manual clutch; Men Tike is pinned at an arbitrary position, and lower to the requirements of installation space of body top, practicality is stronger.

Fig. 3 is the transmission mechanism schematic diagram of the utility model garage door door lifter.

Fig. 4 is for to show the cross section view along A-A as Fig. 3.

Fig. 5 is the structural representation of the utility model garage door door lifter motor.

The specific embodiment as shown in Figure 1, 2, the utility model garage door door lifter has motor 1, steel track 18, transmission device, it is steel scroll bar axle in the motor 20 and steel turbine 2 engagements (showing as Fig. 5) that are socketed on the hollow tubular axis 19 of steel, and hollow tubular axis and turbine to pass through screw affixed.The hollow tubular axis and steel hollow drive shaft 3 interference fits of motor output, the torsion axis 21 that is socketed with torsion spring 13 is connected with driving shaft is coaxial by anchor ear 22.Drive on the aluminum reel 16 that steel rope 15 that door-plate 14 moves along track is arranged on torsion axis 21 two ends (showing) as Fig. 3.Along driving shaft 3 axially successively socket be combined with nylon fixedly embedding facing 4, clutch component 5, nylon clutch fixed cover 6, nylon gear wheel 7; Between described clutch component 5 and clutch fixed cover 6, be socketed with steel return spring 8, and steel shipper rope 9 is affixed with electric motor end cap; It is interior and parallel with driving shaft that the two ends of the spacing screw rod 10 of steel are arranged on shell end cover 17, be positioned at the nylon pinion 11 and gear wheel 7 engagements of spacing screw rod one end, adjust nut 23 and be positioned at the other end of spacing screw rod and the steel motor that has return spring is pulled pin and 12 move axially (showing) as Fig. 3,4 along driving shaft 3.

Behind the electric motor starting, power is passed to driving shaft through turbine worm, and the motor afterbody is risen gradually, to horizontal level (showing as Fig. 1) in actual the use; The drive door-plate rises, owing to gear wheel, pinion, until depressing the stall of upper limit motor.When needing the door body fallen, the starter motor driving shaft drives door-plate and falls, and simultaneously spacing screw rod rotates, treat that a body falls fully after, adjust nut and move pushing motor and pull pin, break away from motor the motor afterbody fallen gradually, to vertical state (showing) as Fig. 2; Depress the stall of lower limit motor.Can prevent from during this state by external force the door body to be opened, theftproof is better.As powering-off state occurring in lifting process, the pulling shipper rope makes sliding sleeve move axially with fixing embedding facing along driving shaft to separate, motor is lifted, at this moment can manually garage door be opened, be closed.After operation is finished, unclamp shipper rope, can realize self-locking and antitheft equally.

The utility model garage door door lifter is compared guide rail type of drive such as the T-shape that omitted the top, garage or " C " type track with existing garage door door lifter, so noiselessness in the use; Because power spreads out of through the turbine worm mechanism of motor, can realize that the optional position self locking safety is reliable; Because the sagging body of pushing down of motor afterbody in the time of in off position uses external force the door body can't be lifted; As sudden power in lifting process, then can the door body be opened or be closed by manual clutch; Men Tike is pinned at an arbitrary position; Requirements of installation space to the body top is lower, and practicality is stronger.
