Abstract
The utility model discloses a kind of stopping means that is applied on the door lifter, it is characterized in that this device comprise the screw mandrel that connects with gear train shaft, be installed in the sliding nut on the screw mandrel and be positioned at screw mandrel two ends and can be by two microswitches of sliding nut control, sliding nut is provided with the detent mechanism that prevents that himself from rotating; The utility model is simple in structure, and is easy to use, and these stopping means flexible movements, can guarantee the normal operation of rolling door mechanism; The utility model is widely used on the door lifter of door locks such as rolling-gate, sliding door, garage door.
Description
Technical field
The utility model relates to a kind of stopping means, particularly a kind of stopping means that is applied on the door lifters such as rolling-gate, sliding door.
Background technology
Present employed electric rolling gate door, sliding door etc. are to rotate by the motor drives scrolling mechanism, thereby drive the motion of door lock by scrolling mechanism.Automatically stopping means has been set up in stop motion usually on scrolling mechanism when making a lock reach the precalculated position, and when a lock moved to the precalculated position, the stopping means output signal stopped motor by executing agency automatically like this.Currently used position-limit mechanism generally is slide block groove type, cam-type structure, and the stopping means complex structure of these structures uses inconvenience, and the action underaction makes stopping means be in failure state easily.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of door lifter stopping means of simple in structure, easy to use, flexible operation.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of stopping means that is applied on the door lifter, it is characterized in that this device comprise the screw mandrel that connects with gear train shaft, be installed in the sliding nut on the screw mandrel and be positioned at screw mandrel two ends and can be by two microswitches of sliding nut control, sliding nut is provided with the detent mechanism that prevents that himself from rotating.
Preferred embodiment a kind of as the utility model, described detent mechanism comprises the locating slot that is arranged on the sliding nut external peripheral surface and is installed in the interior backstay of locating slot.
Above-mentioned transmission mechanism can adopt comprise driving gear, with the driven gear of driving gear engagement and with the gear drive of the output gear of driven gear engagement.
The beneficial effects of the utility model are: two microswitches that the two ends that stopping means of the present utility model adopts the screw mandrel that connects with gear train shaft, be installed in the sliding nut on the screw mandrel and be positioned at screw mandrel also can be controlled by sliding nut, and detent mechanism adopts and is arranged on the locating slot of sliding nut external peripheral surface and is installed in the interior backstay of locating slot, thereby it is simple in structure, easy to use, and these stopping means flexible movements, thereby the normal operation of assurance rolling door mechanism.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the perspective exploded view that the utility model and door lifter are installed;
Fig. 2 is the structural representation of backstay and sliding nut among Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, the stopping means that is applied on the door lifter of the present utility model, comprise the screw mandrel 1 that connects with gear train shaft, screw mandrel 1 can rotate under the drive of transmission mechanism, sliding nut 2 is installed on screw mandrel 1, sliding nut 2 is provided with the detent mechanism that prevents that himself from rotating, thereby limit slippage nut 2 can only be along doing axially-movable on the screw mandrel 1.Be provided with two microswitches 3,3 ' at the two ends of screw mandrel 1 one sides, microswitch 3,3 ' and the motor control system of door lifter electrically connect.When starting door lifter, transmission mechanism drives the motion of door lock, sliding nut 2 is done axially-movable on screw mandrel 1 simultaneously, when the door lock moves to the qualification position, sliding nut 2 moves to an end of screw mandrel 1 simultaneously, and touches the control knob on the microswitch 3 or 3 ', microswitch output signal, motor cuts out, thereby make a lock rest on the precalculated position.This stopping means is simple in structure, and is easy to use, and these stopping means flexible movements, thereby guarantees the normal operation of rolling door mechanism.
As shown in Figure 2, detent mechanism can adopt the locating slot 4 that is arranged on sliding nut 2 external peripheral surfaces and be installed in backstay 5 in the locating slot 4, can reach the purpose that prevents that sliding nut self from rotating.Certainly detent mechanism can also adopt other normal structure of doing, and is not described further at this.
Transmission mechanism can adopt gear drive as shown in Figure 1, this gear drive comprise driving gear 6, with the driven gear 7 of driving gear 6 engagement and with the output gear 8 of driven gear 7 engagements.
Certainly, stopping means of the present utility model not only adapts to by gear-driven door lifter, also be adapted to simultaneously the door lifter by other transmission mechanism transmissions such as chain gear transmission, when the door lifter that applies to as the chain wheel driving mechanism transmission, the technique effect that it reached is identical.
