Detailed Description

The following detailed description is provided to further explain the technical features and advantages of the present invention by referring to the accompanying drawings in combination with the embodiments.

As shown in fig. 1-3, the utility model discloses a door lock structure without having need of hand contact, including door frame 3 and door plant 1, the door plant passes through the pivot and rotationally installs in the door frame, door frame and door plant on be equipped with the part of repelling mutually relatively, this part can be magnet, also can be spare parts such as compression spring or hydraulic buffer, the concrete function is that let door plant and door frame atress respectively make the two separate each other, draw-in groove 2 has been seted up to the door frame bottom, install on the door plant with draw-in groove matched with lock body, the lock body include set bar 7, set bar one end runs through guide way 6, the door plant lateral part is located to the guide way, the articulated connecting rod 5 of set bar other end, the button 10 is rotationally connected to the connecting rod, the button is telescopically installed in the cavity of door plant, set.

Further, the guide groove is arranged on the door panel, the guide groove corresponds to the clamping groove in position, the lock bolt is inserted into the clamping groove or is far away from the clamping groove along the guide groove, specifically, rotating shafts are respectively processed on the grooves of the lock bolt and the button, through holes matched with the rotating shafts are respectively processed at two ends of the connecting rod, the button moves back and forth to drive the connecting rod to rotate in a small range, and the lock bolt can only move forward or backward along the guide groove due to the limitation of the guide groove, so that the lock bolt can be inserted into the clamping groove or is far away from the clamping groove, and the door panel can be.

Further, the groove of the button is perpendicular to the cross-sectional circle of the button, and the groove limits the rotation range of the connecting rod. The door comprises a door plate, a button, a first magnet and a second magnet, wherein the button is placed in an opening cavity of the door plate, one end of the button faces to an opening of the door plate, the other end of the button is fixed with the second magnet 9, the second magnet and the first magnet 8 are oppositely arranged in the same pole direction, and the first magnet is installed in the opening cavity of the door plate. The second magnet and the first magnet repelling in the same direction are both permanent magnets, so that the service life is long, the repelling force is stable, and other parts with equivalent effects such as springs can be used for replacement.

Furthermore, the door frame is provided with a third magnet 4, the door panel is fixed with a fourth magnet which is arranged opposite to the third magnet in the homopolar direction, the third magnet and the fourth magnet which repel in the same direction are permanent magnets, the service life is long, the repelling force is stable, and other parts with the same effect, such as springs, can be used for replacement.

Furthermore, the top of the lock bolt is provided with a lock bolt which penetrates through the guide groove and is arranged opposite to the clamping groove. The cross section of the lock tongue is in a quarter arc shape, and the lock tongue at the front part of the lock bolt can also be a round angle with a certain curvature, so that the door plate and the door frame can be conveniently locked. The button is the cylinder of reducing cross-section, and is specific, and the part circle cross-sectional dimension that the button stretches out the door plant is less than the part circle cross-section that can not directly observe in lieing in the door plant, and the button is spacing by the trompil on the door plant promptly, and the button receives external action force and inside repulsion force effect, can make reciprocating motion in the door plant, and then, the set bar can make reciprocating motion in the guide way.

The working principle of the device is as follows: under natural state, the door plant is in the open mode under the mutual repulsion of third magnet and fourth magnet, and the state of lock body this moment is, and the button stretches out to the outermost of door plant under the mutual repulsion of first magnet and second magnet, and two magnet intervals are the longest, and the set bar stretches out the longest along the guide way. When the people impels the door plant to close to the door frame, generally play the door plant with the foot, the button then moves to door plant inside, the cambered surface of the spring bolt of set bar is to nearly door frame, simultaneously along with the repulsion force continuation motion between two magnet is overcome to the button, the connecting rod small amplitude rotates, drive the set bar and retreat in the guide way to the lock body, simultaneously until the door plant gets into in the door frame completely, after the power that promotes to close the door disappears, the button is at the door plant outward movement under the mutual repulsion effect of first magnet and second magnet, the button removes the small amplitude rotation of drive connecting rod, and then drive the set bar along the draw-in groove direction motion of guide way to the door frame, at last get into the draw-in groove. On the contrary, when the door needs to be opened, the button is pressed down by feet, the lock bolt withdraws from the clamping groove, after the feet are loosened, the door plate is opened under the mutual repulsion action of the third magnet and the fourth magnet before the lock bolt returns to the clamping groove.

The utility model discloses the purpose of device, through the reciprocating motion of button, the advance and retreat of control set bar, and then realize unblanking and close the lock, the unclean hand contact lock when having avoided opening the door to close the door prevents that the pollutant on hand from passing through the lock propagation, does not increase the complexity of opening the door and closing the door in addition.
