Compared with the prior art, the application has the beneficial effects that:

1. this door fence with triple door opening and closing function, big revolving door body passes through the articulated assembly at upper left corner and the lower pivot subassembly and the door frame swivelling joint of lower left corner, big revolving door lock body subassembly is installed to big revolving door body upper right corner, big revolving door body mid-section movable mounting has the well revolving door body, well revolving door body passes through well revolving door pivot subassembly and big revolving door body swivelling joint, well revolving door body below movable mounting has little revolving door body, little revolving door body passes through little revolving door pivot subassembly and well revolving door body swivelling joint, little revolving door body can supply small-size pet such as cat to pass through, after the pet passes through, little revolving door body can be closed by gravity effect voluntarily, well revolving door body can supply large-size pet such as large-scale dog to pass through, big revolving door body can be used to open the back and supply adult or child to pass through, therefore this door fence is applicable to more service scenarios, the practicality has been improved.

2. This door fence with triple switch door function, big swing door body and door frame pass through hinge assembly connection, through set up the semicircle groove at the top terminal surface of projection, oblique cambered surface, protruding cambered surface and plain end face, hinge spring is cup jointed in the spliced pole outside, and install the bearing between spliced pole and spliced portion, open big swing door body, big swing door body drives big swing door hinge rotation, the bearing in the big swing door hinge is from the semicircle groove of the department in proper order, roll to the plain end through oblique cambered surface and protruding cambered surface, because the height of protruding cambered surface is higher than the plain end face, protruding cambered surface can restrict its back roll, promptly when opening the angle is greater than 90 degrees, big swing door body can keep opening state because of being from the low side to the eminence, because of the action of gravity so there is certain damping effect, on the other hand, because big swing door hinge can upwards move, so splicing pole drives spring end cover upwards to compress hinge spring, there is the damping effect, two kinds of damping effect can guarantee that even can not open big door body easily under the unblock state, simultaneously, when opening the angle is greater than 90 degrees, and the thrust is only need to be when the bearing is high swing door body at the moment, the moment is required to be closed at the cambered surface, the moment is high enough, if the thrust is high enough, the thrust is realized, and the automatic swing door body can be closed, and the automatic door body is closed, and if the thrust is easy is because of the top is high enough to be rotated, the thrust at the top is high enough, and the thrust is high down.

3. This door fence with triple switch door function through setting up big spiral door lock body subassembly, can be firm with big spiral door body locking, prevent child from opening, simultaneously, through installing safety switch, safety switch is under the effort of third spring, make the locking piece of the upward perk that its right side middle part set up pass the slot and insert the locked groove in, only through pushing sliding switch can't unblock to the left this moment, only when upwards pressing safety switch, make the locking piece break away from in the locked groove, promote sliding switch and just can make big spiral door lock body subassembly unblock to the left side simultaneously, this kind of unblock mode can effectively avoid children to unlock big spiral door lock body subassembly easily, because children's hand is very little, hardly press safety switch and promote sliding switch simultaneously, improve the reliability of big spiral door body locking greatly, make it have high security.

4. This door grating with triple switch door function through setting up smooth circular arc chamfer at the plug tip, and hasp chamber outside symmetry is provided with the arcwall face, simultaneously, installs second spring and tapered end in the inside slip intracavity of lock core to make under the circumstances that keeps sliding switch motionless, direct inwards press the tapered end also can make its retract slip intracavity, when closing the big revolving door body, the plug of tapered end right-hand member contacts with the arcwall face in the hasp chamber outside, thereby forces the tapered end to retract slip intracavity, conveniently closes the big revolving door body.

5. This door fence with triple switch door function still installs big rotatory door shield on big rotatory door bottom tube right side, and big door shield symmetry installs in the both sides of pipe box, and accessible 90 degrees rotations are adjusted big door shield and are opened or are closed during the use, and two big door shields can only be opened one of them or two simultaneously to the direction that the control big rotatory door body was opened, restriction it can only inwards or outwards open, when two big door shields all close, also plays another layer of guarantee to the fastness that big rotatory door body was closed.
