Abstract
The utility model relates to a rolling shutter door scroll for places, such as a household garbage, a commerce store, a warehouse, etc. The utility model comprises a main shaft 4, end covers 1, 14 and rolling curtain wheels 7, 9. Both ends of the main shaft 4 are fixed on a wall by the end covers, and the main shaft has free rotation, the rolling wheels are fixedly installed at both end parts of the main shaft 4. The utility model is characterized in that the main shaft 4 is provided with tension springs 5, 12, one end of the tension springs is fixedly installed on the end covers, the other end is fixedly installed on the rolling curtain wheels, the tension springs can rotate as the rolling curtain wheels to obtain upward torque force, and a door curtain can be rolled up automatically under the condition of no external force. Thus, the utility model can roll up or release down the door curtain conveniently in a manual time.
Description
The utility model relate to a kind of be used for field boundarys such as family garage, commercial shops, warehouse rolling door, be specifically related to a kind of rolling door spool, belong to the daily living article technical field.
Rolling door has electrodynamic type rolling door, manual rolling door or electric and hand formula rolling door convenient to both etc.Electric rolling door or electric and hand formula rolling door generally all do not have tension spring on the spool.Roll or put down by door curtain opener control door curtain when electronic, but be out of order and adopt when manual when running into power failure or opener, lean on hoist that door curtain is sling, it is very inconvenient to operate, and it is time-consuming again to require great effort.Though on simple manual its spool of rolling door shell fragment is housed, extremely complexity is installed, easy break-down.
The purpose of this utility model is to provide a kind of novel rolling door spool that can easily door curtain be rolled or put down again when simple in structure, manual.
The utility model is achieved in that a kind of rolling door spool, comprise main shaft, end cap and roller shutter wheel, the main shaft two ends are fixed on the wall by end cap, main shaft is free to rotate, and the roller shutter wheel is installed in the main shaft both ends, is characterized in that device has two tension springs on the main shaft, one end of this tension spring is fixed on the end cap, the other end is packed on the roller shutter wheel, and can rotate with the roller shutter wheel, makes main shaft obtain a torsion upwards.
Compare with existing rolling door spool, the utility model is owing to installed two tension springs on former main shaft, and two ends that make spring are installed in respectively on end cap and the roller shutter wheel, when door curtain moves down, spring one end rotates with the roller shutter wheel, and obtains torque upwards, and door curtain can be rolled freely under the situation of no external force, therefore the utility model assembling simple in structure, easy, working stability can be rolled door curtain or put down easily when needs are manual.
Fig. 1 is a general structure schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model being done one describes in detail:
As shown in Figure 1, the utility model is mainly taken turns 7,9, is formed by main shaft 4, two end cap 1,14, two tension springs 5,12, two roller shutters.Main shaft 4 two ends are fixed on the wall by end cap 1,14, and main shaft 4 is free to rotate.Two roller shutters wheel, 7,9 usefulness roller shutters wheel fixed mount 8,10 is packed on the main shaft 4.Two tension springs 5,12 place 1,14 of roller shutter wheel 7,9 and end caps, and the one end is packed on the end cap 1,14 by spring anchorage bracket 15,13, and the other end is packed on the roller shutter wheel fixed mount 8,10 with spring anchorage bracket 6,11, and take turns 7,9 rotations with roller shutter.Make main shaft that one torsion that makes progress be arranged.The rolling door door curtain is fixed on the roller shutter wheel 7,9, and door curtain is rolled freely under the situation of no external force.When electronic on main shaft 4 device one sprocket wheel 3, can send the power of motor to main shaft 4 by sprocket wheel 3, thereby the roller shutter wheel is rotated, can make rolling door roll or put down.
