Description
Technical field
The present invention relates to the doors of rotary type.
Background technology
When in open state, when having big wind, door can be blown and be closed door.Family has child or old
People, when they enter house or go out room, child, which has a lively disposition, to be liked against doorframe, and since body is weaker, walking when needs old man
Doorframe is helped to walk.When encountering strong wind and blowing, if old man or child at this time with hand steered doorframe, if do not paid attention to
Door closes suddenly, and the reaction of old man and child are not grown up acumen, cannot timely fast retractile hand, often send out
The case where raw door crushes hand.
Invention content
The invention is intended to provide a kind of door with automatic pinch resistant functionality, it is easy in big wind with solving door in the prior art
The problem of people being crushed under dynamic.
The door with automatic pinch resistant functionality in this programme, including doorframe and door leaf, door leaf is hinged with doorframe, is set on doorframe
There are arc-shaped the first magnetic block and the second magnetic block, form channel between the first magnetic block and the second magnetic block, first is magnetic
Block be mutually parallel with the second magnetic block and it is heteropolar be oppositely arranged, the rotation in the center of circle and door leaf of the first magnetic block and the second magnetic block
Axis collinear, conducting rod is installed on door leaf, and conducting rod passes through channel；Side of the door leaf far from pivot center is equipped with groove, recessed
It is equipped with air bag in slot, is equipped on door leaf to the air pump of airbag aeration, power supply and slide rheostat, air are installed on door leaf
Pump, slide rheostat and power supply are sequentially connected in series, and slide rheostat includes metallic rod and slide plate, and slide plate is equipped with magnet piece, slide plate
Side be equipped with spring, spring is fixedly mounted in metallic rod, and the other side of slide plate is equipped with electromagnet corresponding with magnet piece, electricity
Magnet is fixedly connected with door leaf, and electromagnet is connected with conducting rod.
First magnetic block and the second magnetic block are set, for generating magnetic field.Channel is set, is moved in the channel for conducting rod
Dynamic and cutting magnetic induction line.First magnetic block and the second magnetic block are designed as arc, and the first magnetic block and the second magnetic block
The center of circle it is conllinear with the pivot center of door leaf, when door leaf being made to rotate, the linear velocity of conducting rod is equal to conducting rod cutting magnetic induction line
Movement speed.Air bag is set, and after airbag aeration expansion, the volume of air bag increases, to stop that door leaf is closed.Air pump is set,
For giving airbag aeration.Slide rheostat is set, it is big to change electric current for changing the resistance sizes of circuit where air pump
It is small.Spring is set, is resetted for slide plate.Magnet piece and electromagnet are set, the magneticaction between electromagnet and magnet piece is passed through
And slide plate is driven to move.Conducting rod is set, for cutting magnetic induction line to generate induced current, and then electricity is provided for electromagnet
Stream.
Operation principle：The slide plate of slide rheostat is in close to the position of electromagnet under the action of the spring, is slided at this time
Rheostatic resistance value is maximum, and air pump obtains the electric current of very little and is in standby；When wind blows door leaf from open state
When to closed state, the velocity of rotation of door leaf is to be getting faster.Door leaf band moving conductive rod accelerates, to make conduction
Bar does the movement for accelerating cutting magnetic induction line in the magnetic field in channel, will produce induced current, and induced current in conducting rod
Size it is directly proportional to the movement velocity of conducting rod, so, when conducting rod accelerates, the electric current that is generated in conducting rod
Gradually increase.Since electromagnet is connected with conducting rod, so the electric current that electromagnet obtains also gradually increases, thus electromagnet generates
Magnetic force also gradually increase, and then the repulsive force between electromagnet and magnet piece is made to increase, to make slide plate move, compressed simultaneously
Spring.When slide plate moves, the resistance of slide rheostat is gradually reduced, and to which the electric current for making air pump obtain gradually increases, makes sky
Air pump accelerates to inflate into air bag, makes air bag rapid expanding.When door leaf is closed soon, the air bag after expansion offsets with doorframe, from
And prevent door leaf from closing.
Compared with prior art, it is the advantages of this programme：1, by the way that air bag is arranged, when wind blows door leaf rotation, profit
The closing of door leaf is hindered with the air bag of gas expansion, people is crushed so as to avoid door leaf.2, door leaf is blown using wind to lead to drive
Electric pole accelerates, and to realize the aeration speed of control air pump, and then realizes the promptness and automaticity of inflation.
3, since air bag has elasticity, when door leaf rotates, air bag has cushioning effect when hindering door leaf to close, and avoids door
Enormous impact force when fan rotation is directly passed to doorframe, to avoid causing the damage of doorframe.4, usually normally at closing time,
Door leaf is closed using smaller speed, keeps the electric current that conducting rod generates smaller, air pump is insufficient to allow largely to be inflated into air bag,
To make air bag not expand and hinder the normal switching-off of door leaf faster.
Further, the conducting rod is made of copper material.The resistance of copper is smaller, can reduce conducting rod itself to electric current
Consumption.
Further, the power supply is accumulator.Power supply facilitates the installation of power supply by the way of accumulator, while
The function of causing door to lose anti-pinch without worrying power failure.
Further, the air pump is vortex air pump.It is by the rotation of blade when spiral vortex type air pump work come real
Existing, the rotation of blade is not likely to produce vibration, to which noise is smaller.
Further, the opening direction of the groove and the angle of door leaf plate face are 135 °.Air bag is facilitated to be expanded from groove
After can be with skewed horizontal load between door leaf and doorframe.
Further, the air bag is in circular ring shape.It is circular ring shape by airbag design, less gas can be used just to make air bag
Expansion, to which there are one larger outer profiles for tool, compared with spherical envelope, under identical outer profile, needed for annular air-pocket
Gas is less, so as to select the air pump compared with small dimension, to save cost.
