Detailed Description

The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.

As shown in fig. 1 and 2, the keeper for the one-way door comprises a rotating member 2, a V-shaped buckle 3, a keeper 4 and a rotating shaft 7, wherein the V-shaped buckle 3 is fixed on a door shaft 6 by welding through a rivet 1, the rotating member 2 and the V-shaped buckle 3 are connected through the rotating shaft 7, the rotating shaft 7 is fixed on the V-shaped buckle 3, the rotating member 2 is rotatably connected with the rotating shaft 7, and the rotating member 2 can rotate around the rotating shaft 7.

One end of the door bolt 4 is welded on the door frame 5, and the other end of the door bolt passes through a hole formed by the intersection of the U-shaped groove 8 of the rotating member 2 and the V-shaped groove of the V-shaped buckle 3. The door bolt 4 is of a deformed Z-shaped structure, and the angle of the bending part is larger than 90 degrees, as shown in fig. 3.

When the one-way door is in a closed state, the U-shaped groove 8 of the rotating member 2 and the V-shaped groove of the V-shaped buckle 3 jointly act to clamp the door bolt 4; assuming that the side of the one-way door where the door bolt is installed is the inner side, the one-way door can only be opened from the inner side. When the door needs to be opened, the rotating member 2 is firstly pulled upwards by hands to break a closed hole formed between the U-shaped groove 8 and the V-shaped groove of the V-shaped buckle 3, the door bolt 4 has a tendency of withdrawing from the U-shaped groove 8 of the rotating member 2, then the door is pulled inwards, the door frame 5 rotates inwards along the anticlockwise direction (the overlooking angle), a channel is opened, the door bolt 4 also rotates anticlockwise along with the door bolt, the rotating member 2 is extruded to continue to rotate upwards, and the door bolt 4 is always clamped in the V-shaped groove of the V-shaped buckle 3 and gradually moves towards the V-shaped intersection point of the V-shaped groove. When the door is opened, the rotating member 2 rotates around the rotating shaft 7 as shown in fig. 5. After the door is opened, the door frame 5 is loosened, the door bolt 4 rotates clockwise along with the door frame 5, the door bolt moves towards the opening direction of the V-shaped groove gradually, the rotating member 2 rotates downwards under the action of self gravity, the U-shaped groove 8 of the rotating member 2 clamps the door bolt 4 again, and the one-way door is closed completely.

In the outside of one-way door, because unable operation rotating member 2, keeper 4 blocks all the time in the hole that the U type groove 8 of rotating member 2 and the V-arrangement groove of V-arrangement knot 3 formed, no matter push away or pull door frame 5, can't open the door to realize the one-way current purpose of passageway.

The bolt of the one-way door in this embodiment further includes a locking device, as shown in fig. 1 and 4, the locking device is disposed on the lower side of the door frame 5, and includes L-shaped members 11, a U-shaped buckle 10 and a semicircular buckle 12, the U-shaped buckle 10 and the semicircular buckle 12 are both fixed on the door frame 5, the semicircular buckle 12 is located at the lower left of the U-shaped buckle 10, wherein the U-shaped opening of the U-shaped buckle 10 faces outwards, i.e., in a direction away from the door frame, and the semicircular opening of the semicircular buckle 12 faces inwards, i.e., in a direction towards the door frame, so that a closed loop is formed between the semicircular buckle 12 and the door frame.

When the one-way door is normally used, namely people normally pass through, the vertical edge of the L-shaped component 11 is inserted into the closed ring of the semicircular buckle 12 and the door frame 5, and the horizontal edge is clamped into the U-shaped clamping groove of the U-shaped buckle 10. when a passage needs to be closed, such as a supermarket, a park and the like, and the one-way door is in a closed state, the horizontal edge of the L-shaped component 11 is screwed out of the U-shaped buckle 10, the L-shaped component 11 is moved downwards, so that the lower end of the L-shaped component 11 is inserted into the positioning round hole arranged on the bottom surface, the door locking effect is realized, and when the passage needs to be closed, the L-shaped component 11 is lifted upwards and rotated, and the horizontal edge of the L-shaped component 11 is clamped into the U-shaped clamping groove of.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
