Description

A kind of full-automatic low pressure remote-controlled curtain machine

The utility model relates to a kind of full-automatic low pressure remote-controlled curtain machine, particularly relates to a kind of operating voltage below 24 volts, and automatic stopping during omnidistance the switching promptly can be used for the full-automatic low pressure remote-controlled curtain machine that curtain can be used for big curtain again.

Use the curtain of common manual, particularly high big cloth curtain more than 5 meters is easily stuck.For example: a new curtain rail uses and often deformed in 6-8 month, thereby stuck, can not normally open and close.This is owing to manually pull unbalance stress or track is unreasonable, is subjected to the rerouting curtain to hang down to stopping for a long time and causes diastrophic result.

At present, the way that addresses this problem is to install 220V additional on pelmet or track girder, linear electric motors, four shortcomings are arranged like this, the first, a rotor wire in tow moves back and forth at stator, long electric wire of time one is aging, and fire or electric shock casualty accident very easily appear in breakage.Second owing to be the 220V high-tension electricity, in case when the short circuit stall occurring, burn-down of electric motor, electric wire is on fire, abnormally dangerous, the 3rd, be again electrode because stator is track, its structure very easily is out of shape, and cause stuck phenomenon, the 4th, because the restriction of length and pulling force, linear electric motors are generally less than 5 meters, therefore can not be used for making the long curtain machine of growing up of 6-12 rice.

The utility model is in order to overcome and to address the above problem and design.Therefore:

The purpose of this utility model provides an operating voltage in the following power supply power supply of 24V, and curtain opens and closes the full-automatic low pressure remote-controlled curtain machine that cuts off the power supply automatically when putting in place.Easily stuck disadvantage when it can effectively solve cloth The curtain rises and close.

The purpose of this utility model is achieved in that the utility model mainly is made up of the curtain rail and the IR remote controller receiver of low-tension supply device, translator reductor.The output of the input of described infrared remote receiver and low-tension supply device is connected the infrared remote receiver output and is connected with reductor motor electrode on the curtain rail, infrared remote receiver receives after infrared transmitter transmits, directly drive the adhesive of relay, thereby drive the reductor motor rotation.Motor reducer is fixed on the rubber wheel of pegging graft on the end reductor driving wheel of curtain rail by guiding trestle, with connect by a spring with caprone cable between the driven pulley that rotates freely on the other end support, receive the signal of infrared transmitter when receiver after, directly drive relay, drive motors thereupon, rubber tire on its speed reducer output shaft opens and closes thereby drive curtain by constituting a reciprocating mechanism on guide bead between nylon rope and the driven pulley.Its major technique feature is:

The full isolating transformer of transformer adopting 12V10-20W in the described power supply device, the PTC of elementary serial connection at transformer automatically transships for greater safety, and overcurrent protector guarantees that transformer can not burnt, thereby reaches low-voltage safety, the purpose of duplicate protection.

The section of the beam of described curtain track is a rectangle, slide rail band reinforcement, and square on the face before the curtain track have an edge that can connect with decoration panel, and this structure is compared not yielding with other track structure, not crooked, thereby guarantees that curtain is not stuck.Because counter-bending, non-deformability is strong, this structure is applicable to big cloth curtain.

Described motor reducer is the few high displacement planetary gear of tooth difference reductor, and wherein speed reducing ratio is 1: 23, the tooth depth coefficient h _a ^*=0.65, radial clearance C ^*=0.35, eccentric shaft is 0.75, modification coefficient 1.2280.When direct current generator is connected power supply, motor shaft drives eccentric shaft, driving rotary arm bearing makes planetary gear self do reciprocal gyration when doing planetary motion, and by crosshead shoe will rotate reposefully output and obtain big moment of torsion, just because of there has been such reductor just to make the output shaft driving wheel obtain bigger moment of torsion.

Receiver of remote-control sytem described in the utility model is No. six receivers of remote-control sytem, and its integration module is LC2200.It promptly has auto-lock function, and interlock function is arranged again, so it is better than other remote controller, in order to realize the automatic stopping that puts in place, installs position limited inching switch in orbit additional, and you only need one press K gently ₁Or K ₂Key curtain or open or close automatically and finish.When need shutting down at an arbitrary position, you press K ₃Key is carried out interlocking and is stopped, in addition, and K ₄-K ₆Key also can be controlled other electrical equipment, as electric light, TV power supply switch etc.

The utility model compared with prior art its advantage is: 1, the track of rectangular cross section is formed beam formula structure with the slideway of band reinforcement, and is not crooked, indeformable, and the curtain motion can be not stuck, therefore applicable to big cloth curtain.2, because the form of transmission is to drive driven pulley by driving wheel friction nylon rope, even when curtain blocks because of other reason, therefore the idle running of speed reducer output shaft overcome friction, can not burn out motor, so the life-span of the present utility model is 10 years-20 years.3, because low-tension supplies etc. adopt PTC protection, therefore safe and reliable no any danger.4, on the track of the present utility model limit switch is housed, can automatic stopping after curtain puts in place.It is interlockable again that receiver of remote-control sytem gets final product self-locking, and can mate with other electrical equipment.Realize that household electrical appliance control automatically, therefore, the utility model is compared with existing 220V high pressure linear electric motors remote-controlled curtain machine, has the long-life, and zero is dangerous, full-automatic, and the multichannel remote control is suitable for characteristics such as face width.Therefore, low-voltage safety remote control curtain machine has more practicality and generalization.It is compared with the 220V window curtain driving mechanism, and it can not only draw curtain, and is applicable to speciality track and big curtain.
