The technical scheme is as follows: the utility model provides an embedded door shelves stopper, base including coaxial setting, the magnetic sheet, the electromagnetism plunger, the top cap, the base space can hold magnetic sheet and electromagnetism plunger, the electromagnetism plunger passes through the telescopic link and is connected with the base, the magnetic sheet passes the telescopic link and fixes and establish in the base, be equipped with the electro-magnet in the electromagnetism plunger, the polarity of the electromagnetism plunger bottom of switch on is the same with the polarity of magnetic sheet or opposite, the electromagnetism plunger upwards pushes up into the top cap along the telescopic link under the magnetic field effect in, the base does not have the difference in height with ground, the top cap does not have the difference in height bottom the AND gate frame.
Further, the electromagnetic plunger is a hemispherical protrusion.
Further, the electromagnetic plunger is made of a soft material. In order to prevent that the friction between the electromagnetic plunger and the top cover is increased and the noise is reduced in the fixing and limiting process, the electromagnetic plunger is made of soft materials.
Furthermore, a spring is arranged in the telescopic rod.
Furthermore, the opening size of top cap is greater than the electromagnetism plunger size, and when the electromagnetism plunger pushed into the top cap, the top cap left the surplus space. In the top cap is gone into by the top cap to the electromagnetism plunger, the surplus space in the top cap can satisfy the user to the accurate judgement of the non-of fixed restriction point, even if the user can not accurately aim at the position of two parts from top to bottom, the electromagnetism plunger still can be pushed into in the top cap, realizes the fixed spacing of door shelves stopper.
Further, a power switch of the electromagnetic plunger is provided on the door handle.
A control method suitable for the embedded door stop limiter comprises the following steps:
step 1: the power switch of the electromagnetic plunger is arranged on the door handle, when the door reaches a locking position, the power switch is pressed to change the current direction of the electromagnetic plunger, a magnetic field opposite to that between the magnetic sheets is generated, and the electromagnetic plunger is jacked into the top cover;
step 2: and the power switch is pressed again, the current direction in the electromagnetic plunger is changed, attraction is generated between the electromagnetic plunger and the magnetic sheet, the electromagnetic plunger is sucked out from the top cover, and the electromagnetic plunger falls into the base.
Has the advantages that: compared with the prior art, the invention has the following remarkable advantages: after the door stop limiter is installed, no height difference exists between the embedded top cover and the bottom of the doorframe; the current direction in the electromagnetic plunger is changed, so that a magnetic field which is the same as or opposite to the magnetic sheet is generated, the electromagnetic plunger moves up and down along the telescopic rod, and the fixed limit of the door is accurately realized; when the electromagnetic plunger falls into the base, the height difference does not exist between the upper plane of the base and the ground, the door stop limiting function is met, meanwhile, daily household cleaning is facilitated, and the potential safety hazard of tripping cannot exist; the control method of the door stop stopper ensures that the embedded magnetic door stop anti-collision stopper is safe and quick.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention is further described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, an embedded door stop anti-collision limiter comprises a base 1, a magnetic sheet 2, an electromagnetic plunger 3 and a top cover 4.
Wherein, base 1, magnetic sheet 2, electromagnetism plunger 3, top cap 4 are coaxial setting, and the device can be divided into first half and lower half, and first half includes top cap 4, and the lower half includes base 1, magnetic sheet 2, electromagnetism plunger 3.
When the door stop limiter does not work, the magnetic sheet 2 and the electromagnetic plunger 3 at the lower half part are completely arranged in the base 1, the electromagnetic plunger 3 is connected with the base 1 through a telescopic rod, and the magnetic sheet 2 is fixedly arranged between the electromagnetic plunger 3 and the base 1; the top cover 4 of the upper half is larger in size than the electromagnetic plunger 3, and a space margin is left in the top cover 4 when the electromagnetic plunger 3 is pushed into the top cover 4.
When the base is installed, the embedded base 1 has no height difference with the ground, and the embedded top cover 4 has no height difference with the bottom of the doorframe.
An electromagnet is arranged in the electromagnetic plunger 3, and the polarity of the bottom of the electromagnetic plunger 3 which is connected with a power supply is the same as or opposite to that of the magnetic sheet 2; when the magnetic field polarity of the electromagnetic plunger 3 is opposite to that of the magnetic sheet 2, the electromagnetic plunger 3 is upwards jacked into the top cover 4 along the telescopic rod under the action of the magnetic field.
Wherein, electromagnetism plunger 3 is the bellied shape of hemisphere, and in electromagnetism plunger 3 was pushed up into top cap 4, the surplus space in top cap 4 can satisfy the user to the accurate judgement of the non-of fixed limit point, even if the user can not accurately aim at the position of two parts about, electromagnetism plunger 3 still can be pushed up into in top cap 4, realizes the fixed spacing of door stop stopper.
In order to prevent the friction between the electromagnetic plunger 3 and the top cover 4 from being increased and eliminate noise in the fixing and limiting process, the electromagnetic plunger 3 is made of soft materials.
In specific practice, a power switch of the electromagnetic plunger 3 is arranged on the door handle, and a user regulates and controls the magnetic field direction of the electromagnetic plunger 3 through the power switch on the door handle, so that the fixed limit and the release of the door are realized.
The invention also provides a corresponding control method of the door stop limiter, which comprises the following steps:
the switch of the limiter is connected with the door handle, the switch on the door handle is pressed to change the current direction of the electromagnetic plunger 3, the magnetic field polarity of the electromagnetic plunger 3 is controlled, and attraction force or repulsion force is generated between the electromagnetic plunger and the magnetic sheet 2 below the electromagnetic plunger.
When the door arrives the locking position, because have certain surplus between electromagnetism plunger 3 and the top cap 4, when user's manual location is accurate inadequately, press the switch on the door handle and also can give the suitable electric current direction of the inside coil of electromagnetism plunger 3, produce the repulsion between electromagnetism plunger 3 and the magnetic sheet 2, slowly push electromagnetism plunger 3 into interior embedded top cap 4 of door, can revise the position of door this moment, just later can be smoothly with the door location and fixed door plant.
When a user wants to close the door, the switch on the door handle is pressed down to supply the electromagnetic plunger 3 with the opposite current direction, attraction is generated between the electromagnetic plunger 3 and the magnetic sheet 2, the electromagnetic plunger 3 is sucked out from the inner embedded top cover 4 of the door, the upper part and the lower part are separated, and when the upper surface of the electromagnetic plunger 3 is superposed with the upper surface of the base 1, the door plate can move.
