Embodiment Construction

[0015] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, an embedded doorstop anti-collision limiter includes a base 1 , a magnetic sheet 2 , an electromagnetic plunger 3 , and a top cover 4 .

[0017] Among them, the base 1, the magnetic sheet 2, the electromagnetic plunger 3, and the top cover 4 are all arranged coaxially. The device can be divided into an upper half and a lower half. The upper half includes the top cover 4, and the lower half includes the base 1. , magnetic sheet 2, electromagnetic plunger 3.

[0018] When the door stopper is not working, the magnetic sheet 2 and the electromagnetic plunger 3 in the lower half are completely placed in the base 1, and the electromagnetic plunger 3 is connected with the base 1 through a telescopic rod, and the electromagnetic plunger 3 and the base 1 are connected between the electromagne...

Abstract

The invention relates to an embedded door stop limiter. The embedded door stop limiter comprises a base, a magnetic sheet, an electromagnetic plunger and a top cover which are coaxially arranged, the space of the base can contain the magnetic sheet and the electromagnetic plunger, the electromagnetic plunger is connected with the base through a telescopic rod, the magnetic sheet penetrates through the telescopic rod to be fixedly arranged in the base, an electromagnet is arranged in the electromagnetic plunger, the polarity of the bottom of the electromagnetic plunger connected with a power source is the same as or opposite to that of the magnetic sheet, the electromagnetic plunger is ejected upwards into the top cover along the telescopic rod under the action of a magnetic field, the base and the ground have no height difference, and the top cover and the bottom of a door frame have no height difference. Compared with a traditional door stop, the embedded magnetic door stop anti-collision limiter and the control method thereof have the advantages that potential safety hazards are avoided, and the embedded magnetic door stop anti-collision limiter is simpler and safer.

Description

technical field [0001] The invention relates to the field of door stops, in particular to an embedded door stop limiter and a control method thereof. Background technique [0002] The currently commonly used door stoppers are mainly divided into two categories: one is fixed, which is composed of two magnetic protrusions installed on the back of the door and on the floor. When the door is opened, the protrusions form an attractive collision To limit the position; the second type is the paddle type, which is composed of a magnetic plate installed behind the door and a paddle on the floor. When the door is opened, the paddle will be attracted by the magnetic plate to tilt up to limit the position. The traditional door stopper is installed on the floor surface, which will form a certain protrusion height on the ground, which is not conducive to daily home cleaning and the danger of tripping pedestrians. Therefore, the conventional door stopper has potential safety hazards and o...
