Description

A kind of automatic door

Technical field

The utility model relates to a kind of automatic door.

Background technology

Existing automatic door comprises doorframe, sliding door, driving mechanism and controller, wherein driving mechanism is by motor, gear reduction and tooth bar are formed, tooth bar and sliding door interfix, motor is moved by gear reduction band carry-over bar and is opened or closed by sliding door, all the time engage between the output gear of wherein rack and pinion reducing gear, if when not having electricity or not knowing well using method, user firmly stirs sliding door, then sliding door is with carry-over bar by force, gear reduction action, thus easily cause skidding between tooth bar and output gear and damage, shorten the application life of automatic door.

Summary of the invention

The purpose of this utility model is to solve life-span of existing in existing automatic door short problem, and the automatic door providing a kind of life-span long.

The purpose of this utility model is achieved in that a kind of automatic door, comprise the motor of doorframe, sliding door, controller and band gear reduction, its middle controller and motor are fixed in doorframe, the sliding door be arranged in doorframe can horizontally slip, the upper rack posts of described doorframe is provided with slider bar, and the tooth bar on this slider bar engages with the output gear of described motor; Described slider bar is provided with magnet, described sliding door is fixed with match with described magnet by moving magnet, when controller controls motor action, output gear is moved by the magnet on the rack drives slider bar on slider bar, magnet is by magnetic force and driven sliding door to move by moving magnet magnetic coupling, thus controls opening or closing of sliding door.

Described sliding door hangs on described upper rack posts by suspension member, and described sliding door is positioned at below this suspension member.

Owing to have employed technical scheme described in the utility model, be connected with magnetic between sliding door and the slider bar of movement, during normal operating, motor can realize opening the door or closing the door by the magnetic force between two blocks of magnet, can firmly not overcome the magnetic force between two blocks of magnet during electricity and realize manually, because the suction between two magnet is not limit, even if so the gear reduction in motor also can not be damaged by force with hand propelled sliding door, so can extend the life-span of automatic door.

Detailed description of the invention

See Fig. 1, the doorframe of this automatic door is made up of upper rack posts 91, lower fulcrum bar 92, left branching rod 93, right pole 94 and middle pole 95, and each strut ends welds with the contact position of the corresponding pole contacted or is riveted together; Sliding door is made up of slide door plate 97 and two suspension members 51 and 52, two suspension member 51 and 52 lower ends are fixed with the top of slide door plate 97 respectively, wherein suspension member 51 internal fixtion is by moving magnet, and the roller in two suspension members pushes down upper rack posts makes sliding door can horizontally slip on upper rack posts; Controller 99 is fixed in right pole 94, and the motor 4 of band gear reduction is fixed in middle pole 95 by motor cabinet 40.

Composition graphs 3,4,5,6, slider bar in Fig. 3 is provided with tooth bar 11 and engages (see Fig. 6) with the output gear of the band gear reduction in Fig. 1, magnet on slider bar in Fig. 4 12 with matched by moving magnet 510, wherein by the fixing suspension member 51 in Figure 5 of moving magnet 510.

See Fig. 2, during use, after clicking the wireless launcher 98 on sliding door, wireless launcher sends control signal to controller 99, controller is controlled motor and rotates thus moved by the output gear on gear reduction and the rack drives slider bar on slider bar, magnet on slider bar drives sliding door to move by the magnetic force between the two of being selected by moving magnet in suspension member, thus realizes opening the door or closing the door; The magnetic force that only need firmly overcome between two magnet during electricity is not wherein had equally with common door to realize opening the door or closing the door.
