Description

A kind of translation door

Technical field

The present invention relates to the door of opening or closing, particularly a kind of translation door with integral form.

Background technology

Door is the important component part of building, and common door comprises the retractable door of opening or closing by stretch mode, the door of opening by rotation mode, and the translation door that opens and closes of the mode by translation.

The general form that adopts plug-in tooth bar or built-in chain of the transmission mechanism of existing translation door, wheel and rack or sprocket wheel and chain are owing to self drive mechanism and manufacturing tolerance, and the operation noise is big, and it is not attractive in appearance to get rusty easily, and cost is also higher relatively simultaneously.

Summary of the invention

The object of the present invention is to provide a kind of translation door, it is by the friction-driven of driving wheel with door body slide rail, and driven pulley and directive wheel be respectively at the four sides inwall formation friction pair of slide rail, thereby moves smooth-goingly, and noise is little, and cost is low.

The technical scheme that realizes the object of the invention is: a kind of translation door, comprise a body, the track and the driving box that are connected with the door body, driving box has driving wheel and driven pulley, it is characterized in that: driving wheel and track constitute friction pair, power source through worm and wormwheel to the driving wheel transmitting torque.

And described driving wheel is connected with worm gear, and the worm screw that cooperates with worm gear is 2～6 worm screws, and lead angle is got 6 °～20 °.

And having 1～4 pair of driven pulley parallel on the described driving box with driving wheel, and 1～4 pair of directive wheel vertical with driving wheel, driven pulley and directive wheel constitute friction pair with the four sides inwall of track respectively.

And has arrangement of clutch between motor and the worm screw, this arrangement of clutch comprises the clutch casing, seat is stirred in the clutch that is connected on the clutch casing, and be arranged on clutch shaft in the clutch casing, have clutch yoke one end and clutch to stir seat and be connected the other end and cooperate with clutch shaft, clutch shaft one end and worm screw be castellated to be connected the other end and to be with elastic part and to be connected with power source.

And all be coated with rubber on described driving wheel, driven pulley and the directive wheel.

And driving box, arrangement of clutch and power source constitute driver, have one with the rear cabinet of driver horizontal arrangement, this rear cabinet comprises a body and is arranged on 1～4 pair of perpendicular driven pulley and directive wheel on the body, driven pulley and directive wheel constitute friction pair with the four sides inwall of track respectively, driver and rear cabinet are by a pair of bulb seat supports, and the middle part is fixed by nut-screw.

And described power source is the electromagnetic brake motor, and the output shaft of electromagnetic brake motor is connected with clutch shaft.

Advantage of the present invention is: 1. by the friction-driven of driving wheel and track, move smooth-goingly, noise is little.2. because wheel reaches reliable support less, can dwindle wheelspan, reduce the space that the door body takies door opening and Men Tihou.3. driving box and clutch casing are supported on the ground by adjustable for height bracing or strutting arrangement, carcase work requirement and installation requirement have been reduced, also can avoid simultaneously traditional mechanism because flatness error causes two groups of torsion between drive, increase wheel and track wearing and tearing.

The specific embodiment

The present invention will be further described below with reference to embodiment referring to Fig. 1～3.

The present invention relates to the door of opening or closing with integral form, particularly a kind of translation door, comprise a body, the track 19 and the driving box 1 that are connected with the door body, driving box 1 has driving wheel 2 and driven pulley 3, it is characterized in that: driving wheel 2 constitutes friction pairs with track 19, power source 16 through worm screw 6 worm gears 5 to driving wheel 2 transmitting torques.

The door body drives by driving wheel 2 friction with track 19, move smooth-goingly, and noise is little, and the moment of torsion of power source 16 passes through motor output shaft 8, clutch shaft 7, worm screw 6, worm gear 5 and is passed to driving wheel 2.

And described driving wheel 2 is connected with worm gear 5, and the worm screw 6 that cooperates with worm gear 5 is 2～6 worm screws, and lead angle is got 6 °～20 °.

Worm screw 6 is got 6 °-20 ° lead angle, and worm gear 5 and worm screw 6 not self-lockings so when clutch shaft 7 is thrown off with worm screw 6, can manually promote a body, can't the folding translation door when preventing to have a power failure.

Further technical scheme can be to have 1～4 pair of driven pulley parallel with driving wheel 3 on the described driving box, and 1～4 pair of directive wheel 4 vertical with driving wheel 2, driven pulley 3 and directive wheel 4 respectively with the four sides inwall formation friction pair of track 19.

Driven pulley 3 is used for supporting a door body, and the directive wheel 4 vertical with driving wheel 2 can prevent body double swerve when sliding, and avoided track 19 scraping driving wheels 2 and driven pulleys 3, prolonged its application life.

Driven pulley and the combination of the different numbers of directive wheel are not limited only to several modes in Fig. 4～7.

And described arrangement of clutch comprises clutch casing 9, seat 10 is stirred in the clutch that is connected on the clutch casing 9, and be arranged on clutch shaft 7 in the clutch casing 9, have clutch yoke 11 1 ends and clutch to stir seat 10 and be connected the other end and cooperate with clutch shaft 7, clutch shaft 7 one ends and worm screw 6 be castellated to be connected the other end and to be with elastic part 17 and to be connected with power source 16.

Stir clutch yoke 11, clutch yoke 11 drives clutch shaft 7 and throws off with worm screw 6; When clutch yoke 11 resetted, clutch shaft 7 was because the active force of elastic part 17 is connected with worm screw 6 once more, and the moment of torsion of power source 16 just can conduct to worm screw 6.

Further technical scheme also can be all to be coated with rubber on described driving wheel 2, driven pulley 3 and the directive wheel 4.

Rubber-coated on driving wheel 2, driven pulley 3 and directive wheel 4, can damping and silencing, can eliminate the strong collision with track 19 again, improve the durability of track 19 greatly.

And driving box 1, arrangement of clutch and power source 16 constitute driver 18, have one with the rear cabinet 21 of driver 18 horizontal arrangement, this rear cabinet 21 comprises a body 20 and is arranged on 1～4 pair of perpendicular driven pulley 3 and directive wheel 4 on the body 20, driven pulley 3 and directive wheel 4 constitute friction pair with the four sides inwall of track 19 respectively, driver 18 and rear cabinet 21 are supported by a pair of bulb bearing 15, and the driver driving wheel is by the frictional force of nut 13 screw rods 12 adjustings with slide rail.

Driver 18 and rear cabinet are supported on the ground by adjustable for height bracing or strutting arrangement, carcase work requirement and installation requirement have been reduced, also can avoid simultaneously traditional mechanism because flatness error causes two groups of torsion between drive, increase wheel and track 19 wearing and tearing.

Further technical scheme can also be that described power source 16 is electromagnetic brake motors, and the output shaft 8 of electromagnetic brake motor is connected with clutch shaft 7.

The electromagnetic brake motor is automatically locked when not working, and has strengthened the steadiness of door body.

The present invention on the same day with regard to same subject application utility model patent.
