Description

Electric reel

The utility model relates to a kind of spool, particularly a kind of electric reel.

Electric reel is widely used in various rolling door, roller shutter window, curtain and transmits on the conveying arrangement, used electric reel mostly is axostylus axostyle, end at axostylus axostyle is equipped with reduction box and motor, because motor and reduction box are to be located at shaft end, thereby installation institute takes up space bigger, neither attractive in appearance also dangerous, on high-grade curtain, it is contemplated that on the window of luxurious hotel, high-end residential, villa, office premises office motor and reduction box are housed, will be very inharmonious to indoor overall decoration.How the electric reel of outside no motor of a kind of axostylus axostyle and reduction box is provided, has become a big problem in this field.

The purpose of this utility model promptly is to provide the electric reel of outside no motor of a kind of spool and reduction box.

Above-mentioned purpose of the present utility model is realized by following technical scheme.

A kind of electric reel comprises an axostylus axostyle and is connected in the spindle nose at axostylus axostyle two ends, it is characterized in that: this axostylus axostyle is made up of a hollow central siphon and the end cap that is fixedly arranged on the central siphon two ends, and the center of two end cap is provided with centre bore; The shell of one this motor of motor and central siphon Joint, the output shaft of motor is affixed by a deceleration device and a spindle nose, and this spindle nose is overhanging by the centre bore of an end end cap; Set firmly a stopping means that limit switch is housed in another end cap of axostylus axostyle, another spindle nose be housed in the centre bore of this another end cap, also be provided with conducting ring on this spindle nose, this conducting ring external power supply switch, in connect limit switch and motor.

Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:

This deceleration device is the planetary gear deceleration device, or the microwave mechanical reduction gear.

This stopping means is made up of screw mandrel, slide block, two limited blocks, two slide bars and the limit switch that is installed on the limited block, wherein limited block and central siphon Joint, and pass through two slide bars and engage with above-mentioned another end cap, the slide block spiral shell is located on the screw mandrel, and be slidedly arranged on above-mentioned two slide bars this screw mandrel and above-mentioned another spindle nose Joint by slide opening.

Advantage of the present utility model is: all motors, deceleration device and stopping means all are installed in the axostylus axostyle, therefore do not occupy other space, reach purpose of safety attractive in appearance, be particularly suitable for installing and using on the door and window of luxurious hotel, high-end residential, villa, office premises office.

Enumerate a specific embodiment below and engage accompanying drawing the structure that connects of the present utility model is described further:

Description of drawings:

Fig. 1 is a generalized section of the present utility model, does not wherein dissect from the center for this part of the position of the switch in the demonstration limit pseudo-device, only central siphon is cutd open.

Fig. 2 is the A-A sectional view of Fig. 1 of the present utility model.

Fig. 3 is a circuit connection diagram of the present utility model.

As shown in Figure 1, 2, a kind of electric reel of the present utility model comprises axostylus axostyle 1 and is located at the

spindle nose

2,3 at axostylus axostyle 1 two ends.This axostylus axostyle 1 is made up of a hollow

central siphon

4 and 5,6 of end caps being fixedly arranged on the central siphon two ends.The center of two

end cap

5,6 is provided with centre bore.One motor 7, the shell of this motor 7 and central siphon 4 Joints; The output shaft of motor 7 is affixed by a deceleration device 8 and a spindle nose 2, and this spindle nose 2 is overhanging by the centre bore of an end cap 5; Set firmly a stopping means 10 that limit switch 11 is housed in another end cap 6 of axostylus axostyle 1; Another spindle nose 3 is housed in the centre bore of this another end cap 6; Also be provided with conducting ring 9 on this spindle nose 3; These conducting ring 9 external power supply K switch 1, in connect limit switch K2, K3 and motor 7.

This stopping means 10 is made up of screw mandrel 12, slide block 13, two

limited blocks

14,15, two slide bars 16 and the limit switch 11 that is installed on the limited block 14,15.Wherein

limited block

14,15 and central siphon 4 Joints, and by two slide bars 16 and engage with above-mentioned another end cap 6.Slide block 13 spiral shells are located on the screw mandrel 12, and are slidedly arranged on above-mentioned two slide bars 16 by slide opening, slide on slide bar 16 and can be driven by screw mandrel 12.This screw mandrel 12 and above-mentioned another spindle nose 3 Joints.

The

spindle nose

2,3 at above-mentioned two ends is set up in the support (figure does not show) during use, and is held with as shown in Figure 2 square-section and not change.When motor 7 energising rotations, the central siphon 4 that drives with its Joint is rotated.Be installed in the stopping means 10 in the axostylus axostyle other end, screw mandrel 12 wherein is and spindle nose 3 Joints, can not rotate, the

limited block

14,15 and the slide block 13 that engage with end cap 6 by slide bar 16 then rotate synchronously with axostylus axostyle 1, because slide block 13 is screwed together on the screw mandrel, along the screw mandrel axially-movable,, and make motor outage stall with the rotation of axostylus axostyle 1 up to the touching limit switch.

In the present embodiment, this deceleration device 8 is mechanical reduction gears, comprising, planetary gear deceleration device or microwave mechanical reduction gear.

Figure 3 shows that circuit diagram of the present utility model.Wherein motor is a direct current generator, and power supply is a dc source.Can carry out rotating control to motor by a reversing switch K, connect again on the circuit of motor and also be connected in series two travel switches, make that the row slide block touches Cheng KaiguanK 1 (or K2) and cuts off electric motor loop after spool forwards certain revolution to, make the motor stall.During counter-rotating, be touched other diode D2 (or D3) the formation motor path of Cheng KaiguanK 1 (or K2), make the motor reverse rotation and Cheng KaiguanK 1 (or K2) is connected by being attempted by.
