Description
Technical field
The utility model relates to green house of vegetables facility technology field, relates in particular to a kind of curtain rolling-up machine for vegetable green house special-purpose inverted instrument.
Background technique
The type of existing curtain rolling-up machine for vegetable green house mainly contains two kinds, and the one, gear driven type, the 2nd, scroll drive type.The check of gear driven type shutter is ratchet mechanism, and major part is ratchet, ratchet and friction plate, utilizes the associating of friction plate and ratchet mechanism non-return.Subject matter is non-return unreliable, poor stability, and must be often the spring on renewal of facing renewal and the ratchet more, otherwise, non-return inefficacy.Because non-return unreliable, or untimely more renewal of facing renewal and spring, roll under the straw screen or mat roller of rolling, cause the accident, or even the major accident of personal injury.The check of scroll drive type shutter is by worm geared latching characteristics, and is non-return reliable, safe, but cost is high, efficient is low, uses not as good as the gear transmission formula and popularizes.
Summary of the invention
The utility model is exactly problem unreliable for the gear driven type shutter converse stopping mechanism that solves the prior art existence, that need frequent maintenance; A kind of curtain rolling-up machine for vegetable green house special-purpose inverted instrument is provided; Have the advantages such as Maintenance free between simple in structure, non-return reliable, spreadable life, life-span be long, realized the Bidirectional stop inverse function.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of curtain rolling-up machine for vegetable green house special-purpose inverted instrument, comprise driving shaft, driven shaft, housing, one end of driving shaft is cylinder, one end of driven shaft is cylinder, cylinder and cylindrical fit, cylinder end and cylindrical end are respectively equipped with the elongated slot of perforation, be provided with the long strip tongue piece of cooperation in the elongated slot, the external cylindrical surface of driven shaft end is provided with four inclined-planes, four inclined-planes are symmetrical in twos with horizontal plane and vertical surface by axis centre, separate by elongate body respectively between per two inclined-planes with the vertical surface symmetry, it is large that the interior internal surface of hole of inclined-plane and housing forms the space near elongate body, away from little space, elongate body space, be respectively equipped with roller in the space, the driven shaft cylindrical is connected by bearing fit with the housing endoporus, and the driving shaft cylindrical is connected by bearing fit with the housing endoporus.
Described elongate body is provided with through hole, is provided with spring in the through hole, spring and roller-contact.
Working principle of the present utility model: an end of driving shaft of the present utility model is cylinder, one end of driven shaft is cylinder, cylinder and cylindrical fit, cylinder end and cylindrical end are respectively equipped with the elongated slot of perforation, be provided with the long strip tongue piece of cooperation in the elongated slot, the external cylindrical surface of the end of driven shaft is provided with four inclined-planes, four inclined-planes are symmetrical in twos with horizontal plane and vertical surface by axis centre, separate by elongate body respectively between per two inclined-planes with the vertical surface symmetry, it is large that the interior internal surface of hole of inclined-plane and housing forms the space near elongate body, away from little space, elongate body space, be respectively equipped with roller in the space, driven shaft cylindrical and housing endoporus are connected by the bearing II, and driving shaft cylindrical and housing endoporus are connected by the bearing I.Housing in this non-return device is to maintain static, long strip tongue piece couples together driven shaft and driving shaft, when driving shaft rotates, drives driven shaft by the tongue piece and rotates, motion on the driving shaft and transmission of power to driven shaft, motion from the driving shaft to the driven shaft and the transmission of power have been realized.When driving shaft drove the driven shaft rotation, four rollers all were brought to large place, space, and roller does not contact with the internal surface of housing endoporus, is to rotate with driving shaft and driven shaft, did not play a part to stop and rotated.Four little inclined-planes are arranged on the cylndrical surface of the end of driven shaft, per two have an elongate body to separate, the interior internal surface of hole of inclined-plane and housing forms the space of a close elongate body greatly away from little space, elongate body space, when driven shaft when initiatively clockwise rotating, one of left side place that is pressed against large space in the space, place separately in one of the right and following two rollers in two rollers in top, because the space is large, roller does not contact with the interior internal surface of hole of housing, do not play stopping function, but in two rollers in top in one of the left side and following two rollers one of the right driven by frictional force and roll to the little space segment in space, place separately, because the effect of frictional force, driven shaft rotates, these two rollers just roll in little place, more past space, these two rollers just tightly are crowded together driven shaft and housing like this, because housing is to maintain static, so that driven shaft also just turns is motionless, realized the return-stopping function when driven shaft clockwise rotates.In like manner, when driven shaft when initiatively rotating counterclockwise, in two rollers in top in one of the right and following two rollers one of the left side driven by frictional force and roll to the little space segment in space, place separately, because the effect of frictional force, driven shaft rotates, these two rollers just roll in little place, more past space, these two rollers just tightly are crowded together driven shaft and housing like this, because housing is to maintain static, so it is motionless that driven shaft also just turns, the Bidirectional stop inverse function that return-stopping function when so just having realized that driven shaft rotates counterclockwise, this patent have just had.Elongate body is provided with through hole, is provided with spring in the through hole, spring and roller-contact, because the effect of spring force, roller more tightly is crowded together driven shaft and housing, has increased the check effect.
The beneficial effects of the utility model:
1. the utility model non-return structure is reliable, can prevent the generation of the malfunctioning generation that causes the accident, particularly human casualty accident of stop;
2. durable, the Maintenance free of the utility model non-return structure is easy to use.
