Abstract
The utility model discloses an improved retainer designed for electric-doors. The utility model mainly comprises a driving shaft, two or more than two driven shafts and two or more than two gear sets composed of a big base gear and a small base gear arranged by a certain interval. The gear set is connected to the driving shaft and the driven shaft by bell and spigot joint; the gears on the neighboring driving shafts mate each other, the big base gear mates with the small base gear; two final-stage driven shafts are connected to the mechanism of a touch limit-switch, and the driving shaft is permanently connected to an adjusting gear. The utility model improves lead-screw driving in the existing art into staggered driving of a tower-type gear set; the gear set can cause extension driving in transversal direction or vertical direction; multi-stage retaining function of a large-span curtain can be achieved by occupying a space as small as possible, and the retaining accuracy is very high; the utility model is small in size and not restricted by installation conditions.
Description
Technical field
The utility model relates to a kind of stopping means, relates in particular to a kind of gear stop that applies to roller shutter.
Background technology
Apply to the stop in the electric door at present, as shown in Figure 5: mainly comprise screw mandrel 1 ', two nuts 2 ' and two limit switches 3 ' compositions of cooperating with wire rod thread, rotation drive nut 2 ' by screw mandrel 1 ' moves, and then touches the action that limit switch 3 ' limits electric door.For satisfying the size requirements of the electric door that applies to different occasions, existing stop is to realize by the distance that changes between two nuts 2 ', according to present technical level, the rolling door of large span just needs the length of lengthening screw mandrel 1 ' to realize, so, caused the bulky of whole stop, and the screw mandrel after the amount of deflection increasing is yielding, spacing inaccurate to making.
Summary of the invention
At the weak point of above existence, the utility model provides a kind of large span electric door that realizes multistage spacing and locate accurate stop, and described stop volume is small and exquisite, is convenient to install.
For achieving the above object, technical solutions of the utility model are:
A kind of improved electric door stop, it is characterized in that: described stop mainly comprises an initiative drive shaft, the driven power transmission shaft that two bars or two bars are above, two or more big basic circle gears, little basic circle gear are provided with the gear train that forms at interval, described gear train is socketed on above-mentioned initiative drive shaft, the driven power transmission shaft, gear on the adjacent power transmission shaft is engaged with each other, the mode that is engaged with each other is the little basic circle gear of big basic circle gears engaged, and the driven transmission shaft end interlock one of two final stages touches the mechanism of limit switch.
The mechanism of described shake-up limit switch one is fixed on the cam mechanism of the driven transmission shaft end of two final stages.
The mechanism of described shake-up limit switch is fixed on the friction pad of the driven transmission shaft end of two final stages and the T type clutch friction plate that a group is placed through the electromagnet centre bore, one spring housing is located on the T type clutch friction plate, electromagnet is not under the "on" position, described friction pad connects with the friction of T type clutch friction plate, and T type clutch friction plate end outer rim cooperates the bound bit switch to establish a projection.
The usefulness of technique scheme is:
The utility model is improved to cluster gear group staggered transmission with screw mandrel transmission of the prior art, and gear train can take as far as possible little space and just can realize the multistage spacing of large span rolling door laterally or vertically extending transmission, and spacing accurate; Volume is little, is not subjected to the qualification of mounting condition.In addition, this new structure has designed manually or has controlled automatically stopping means.

The specific embodiment
The utility model now is described in conjunction with the accompanying drawings and embodiments.
As shown in Figure 1 and Figure 2: a kind of improved electric door stop, mainly comprise an initiative drive shaft 1, the driven power transmission shaft 2,3 of two bars, identical cluster gear 11,12 and the pinion 13 identical of order socket two on the initiative drive shaft 1 with the little basic circle gear of cluster gear 11,12, two driven power transmission shaft 2,3 same sequence socket gears, order be a gear wheel 21,31 identical with the big basic circle gear of cluster gear 11,12 on the initiative drive shaft and and initiative drive shaft 1 on the identical cluster gear 22,23,32,33 of cluster gear 11,12.Be subjected to power to order about the gear train of initiative drive shaft 1 interlock on it, at first the pinion on the initiative drive shaft 13 meshes the big basic circle gear of the cluster gear 23,33 on the driven power transmission shaft simultaneously, link the simultaneously big basic circle gear of the cluster gear 12 on the initiative drive shaft 1 of its little basic circle gear rotates, the staggered engagement of so big or small basic circle shown in Fig. 3,4 is until the final stage transmission: 21,31 on the driven power transmission shaft of little basic circle gears engaged of the cluster gear 11 on the initiative drive shaft 1.As shown in Figure 3: this full mold stop cam mechanism 5 that is fixedly connected on the appropriate location of two driven power transmission shaft ends, the cam mechanism 5 interlocks protruding place on it touches limit switch 6 work, realizes the multistage spacing of large span electric door, precisely the location.In addition, as shown in Figure 4: the utility model also can connect firmly two friction pads 51 and one group of T type clutch friction plate 53 that is placed through electromagnet 52 centre bores in the appropriate location of two driven power transmission shaft ends, one spring 54 is sheathed on the T type clutch friction plate 53, electromagnet 52 is not under the "on" position, under the effect of spring restoring force, described friction pad connects with the friction of T type clutch friction plate, T type clutch friction plate 53 end outer rims cooperate bound bit switch 6 to establish a projection 531, when electromagnet 52 logical powering on, T type clutch friction plate 53 overcomes the restoring force of spring, leave the contact of limit switch, so control the spacing purpose of electric door upstream and downstream with electronic mode of operation.The spacing technology of new structure like this, the visual rolling door of manufacturer stride end size increase or reduce the bar number of driven power transmission shaft, also can be by increasing or reduce the spacing requirement that number that power transmission shaft cogs satisfy the different spans rolling door, thus, saved the shared space of stopper member, the volume of stop significantly diminishes, remedied all the time, the installation of Large Electric door sticks to the restriction that occasion is installed, and fully satisfies the demand of consumption market.
