At present, the roller shutter of electric roll-up door mechanism in use, deforms by the normal phenomenons such as derailing, card rail that occur under high wind condition, and reparation difficulty is large, cost is high, and impact is used.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of wind-proof device, after can making the roller shutter of door-rolling machine deform under high wind condition, still can not derail and not block rail along the smooth and easy slip of guide rail, and normal lifting, guarantees routine use.
For solving the problems of the technologies described above, the utility model is realized as follows: a kind of wind-proof device for door-rolling machine described in the utility model comprises guide rail, roller, roller support, castor and rolling slat.
Described guide rail is spill, in the guide wall of both sides, is equipped with insulating course, and two insulating courses are in same plane and the distance more bigger than roller shutter thickness of being separated by between the two, and rolling slat is connected between two insulating courses; Guide rail top closure, and on center line, have rectangle elongated slot.
Described roller support is semicircle by two one end, one end is that trapezoidal roller support plate forms, two roller support plates are separated by than the bigger distance of roller thickness and are fixed on guide rail inwall, between support plate, semicircle one end has through hole, roller shaft is fixedly connected with roller and with roller support through the through hole on roller support respectively, roller can freely rotate around roller shaft, is uniform-distribution with many group roller supports on the inwall of guide rail both sides, and every group is provided with two groups of roller supports side by side.
Described rolling slat two bottom sides has four through holes, and rolling slat two bottom sides has four through holes, and castor is connected in through hole, and can rotate along its axis; The both sides that are distributed in rolling slat of described castor symmetry; The middle part cylinder diameter of caster axle is greater than the cylinder at two ends, and caster axle, through the through hole of rolling slat, is connected with bearing on two terminal circle cylinder, and bearing outer ring is connected with castor, and castor can freely rotate around caster axle; Rolling slat both sides are inserted in the spill cavity of guide rail, and castor can be along the insulating course scroll-up/down in guide rail.
Good effect of the present utility model: a kind of wind-proof device for door-rolling machine described in the utility model is at rolling slat lifting process, if run into high wind, rolling slat bottom castor is stuck on guide rail insulating course all the time, can guarantee that rolling slat two ends do not deviate from from guide rail, and still can slide up and down along guide rail, there is not moderate finite deformation in the part rolling slat that the many groups roller on guide rail inwall can guarantee to insert in guide rail, rolling slat still can be free to slide along guide rail.

The specific embodiment
As shown in Figures 1 to 5, a kind of wind-proof device for door-rolling machine described in the utility model comprises guide rail (1), roller (3), roller support, castor (4) and rolling slat (2).
Described guide rail (1) is spill, in the guide wall of both sides, is equipped with insulating course, and two insulating courses are in same plane and be separated by between the two than the bigger distance of rolling slat (2) thickness, and rolling slat is connected between two insulating courses; Guide rail (1) top closure, and on center line, have rectangle elongated slot, can make rolling slat (2) when sliding up and down, pass guide rail (1) top.
Described roller support is semicircle by two one end, one end is that trapezoidal roller support plate (5) forms, two roller support plates (5) are separated by than the bigger distance of roller (3) thickness and are fixed on guide rail (1) inwall, between roller support plate (5), semicircle one end has through hole, roller shaft (6) is respectively through the through hole at the through hole on roller support and roller (3) center and be fixedly connected with roller support plate (5), roller (3) can freely rotate around roller shaft (6), roller shaft (6) is cylindrical, on the inwall of guide rail (1) both sides, be uniform-distribution with many group roller supports, every group is provided with two groups of roller supports side by side, can make rolling slat (2) both sides that moderate finite deformation does not occur still can freely slide up and down simultaneously.
Described rolling slat (2) two bottom sides has four through holes, and rolling slat (2) two bottom sides has four through holes, and castor (4) is connected in through hole, and can rotate along its axis; The both sides that are distributed in rolling slat (2) that described castor (4) is symmetrical.The middle part cylinder diameter of caster axle (8) is greater than the cylinder at two ends, caster axle (8) is through the through hole of rolling slat, on two terminal circle cylinder, be connected with bearing (7), bearing (7) outer ring is connected with castor (4) centre bore, and castor (4) can freely rotate around caster axle (8); Rolling slat (2) both sides are inserted in the spill cavity of guide rail (1), and castor (4) can be along the insulating course scroll-up/down in guide rail (1), and is stuck in guide rail (1) spill cavity, can under high wind effect, not derail.
The course of work of the present utility model:
A kind of wind-proof device for door-rolling machine described in the utility model, when door-rolling machine opens and closes operation, rolling slat slides up and down along guide rail, under high wind condition, Action of Wind pressure can make it deform on rolling slat, the roller that guide rail inwall distributes can make rolling slat two ends not deform, can guarantee that roller shutter slides normally, because the insulating course of guide rail is stuck in the concave shaped cavity of guide rail by castor, and castor still can slide along insulating course, can there is not derailing and the switching operation of still can easy on and off having slided in rolling slat.
Some principles of work and power of the relevant a kind of wind-proof device for door-rolling machine of the utility model that just explains through diagrams recited above; owing to being easy to carry out on this basis some modifications concerning the technician in constructed field; therefore shown in this manual does not really want a kind of wind-proof device for door-rolling machine described in the utility model to be confined to or in described concrete mechanism and the scope of application; therefore every corresponding modify that may be utilized and equivalent, all belong to the protection domain of the utility model patent.
