Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment
Embodiment device is as a kind of innovative design of automatic door anti-jamming device, for some safety problems that automatic door in modern society brings, as the redesign of center deployment to automatic door structure, reach the object of the modernization design theme meeting the ergonomics such as safety, efficient, hommization.
This kind of automatic door anti-jamming device, comprise cylinder 1, connector 2, Buffer Unit, as Fig. 3, Fig. 9, cylinder 1 adopts solid or hollow cylindrical shape, and the external surface of cylinder 1 adopts shiny surface or frosting, and the two ends of cylinder 1 are respectively equipped with connector 2, connector 2 is equipped with the cylindrical protrusions 3 for being flexibly connected cylinder 1, the two ends of cylinder 1 are respectively equipped with circular groove 4, and protruding 3 are embedded in circular groove 4 respectively, and cylinder 1 rotates around the projection 3 at two ends.
Connector 2 adopts square, connector 2 is provided with through hole 5, Buffer Unit comprises fixed bar 6 and spring 7, the end of fixed bar 6 is fixed on door leaf 8 after the movable through hole 5 through connector 2, spring 7 successively, the sidepiece of door leaf 8 is provided with the walking trough 9 for cylinder 1 movement, cylinder 1 forms the opening and closing end face of door leaf 8, as Fig. 2.The two ends of walking trough 9 are respectively equipped with the walking track 10 holding connector 2 and Buffer Unit, and walking track 10 is located in door leaf 8, as Fig. 3, makes walking track 10 relatively airtight, avoids external impurities enter walking track 10 and stop the movement of connector 2.The inner surface of walking track 10 is smooth, and connector 2 can be slided on walking track 10.
Be provided with between walking track 10 and walking trough 9 and carry out spacing stopper slot 11 to protruding 3.Stopper slot 11 makes cylinder 1 in walking trough 9, and during spring 7 non-pressurized, cylinder 1 is in the most end of walking trough 9; When object is pressed from both sides, object promotes cylinder 1 and moves in walking trough 9, and connector 2 is slided in walking track 10, and spring 7 pressurized, provides certain buffering, as Fig. 3, Fig. 4.After object takes out, spring 7 rebounds connector 2, thus makes cylinder 1 be returned to the most end of walking trough 9.
Connector 2 arranges two through holes 5 side by side, respectively by there being fixed bar 6 in through hole 5, fixed bar 6 is each passed through spring 7, for connector 2 arranges two fixed bars 6 and spring 7, connector 2 is moved makes guiding more accurate, the motive force acted on connector 2 is more balanced, and connector 2 of being more convenient for moves.The length of fixed bar 6 is all greater than the length of stopper slot 11, and cylinder 1 is when in walking trough 9, any scope moves, and fixed bar 6 penetrates in the through hole 5 of connector 2, and fixed bar 6 is led for connector 2.
This automatic door anti-jamming device is located at the contact surface place of two door leafs 8 of clamshell doors respectively, as Fig. 1, when object is pressed from both sides by mistake, provides buffering by the anti-jamming device on two door leafs 8 simultaneously, more can avoid the impaired generation of object.
When this automatic door anti-jamming device clamps object in automatic door closing course, cylinder 1 moves Compress Spring 7 simultaneously to the opposite direction of object and cushions; Draw object that cylinder 1 is rotated outward, object is taken out.
This anti-jamming device makes automatic door be not easy in closed condition to clamp object, and reaches the target of anticipation on the basis considering financial cost benefit.The mode that this device adopts is exactly at the automatic door place of closing while arrange cylinder 1, and this cylinder 1 is connected to buffer.When object is clamped by automatic door, the cylinder 1 being equivalent to be connected to buffer clips object, and because cylinder 1 is rotatable, therefore object can be easy to be removed, thus reaches the target of anticipation.
The advantage of this device is not need to rely on electronic message unit with high costs, only needs simple structure to improve and just can reduce risk.The using method of this device and process are as Fig. 5, Fig. 6, Fig. 7 and Fig. 8, and when having clamped object in automatic door closing course, spring 7 device of its inside can play cushioning effect at once, as Fig. 6, infringement is dropped to minimum with this.Now, because the cylinder 1 clamping object is rotating, so nipped object can be easy to be removed, so, this device just serves the function of anti-pinch.
Compared with existing automatic door anti-jamming device, this Novel anti-pinch device can more effectively tackle some emergency situations, be compared to the optoelectronic induction class anti-jamming device extensively adopted in the market, the cost of this device is cheaper, and operating principle is simpler.
Cylinder 1 adopts elastomeric material to make or adopts photosensitive resin material to be printed by 3D and forms.The device of anti-jamming device and accessory can print according to the size three-dimensional printing technology of concrete automatic door and photosensitive resin material and create, and do not need die sinking to produce in batches.
