Abstract

The utility model discloses a door fence belonging to a device arranged in a doorway or a mouth of a staircase to protect children. An upper lock arranged on the door fence comprises a button, a press-button spring, a hasp, a hasp supporting frame, and a locking compression spring. A block is arranged on the hasp and the locking compression spring is arranged between the block and the hasp-supporting frame. One end of the hasp extends into a chase in an outer door and a hole is arranged in the middle of the hasp. A projection is arranged in the lower portion of the button of which the bottom is a bevel. Half of the bottom extends into the hole in the hasp. After the door is opened, an intrinsic articulation and an extrinsic articulation slide freely on the bevel to close the door due to dead weight. The extending portion of a nut sleeve arranged on the end of the adding extending portion leads the nut sleeve to adjust the length freely within the effective range, thereby the doorframe can be connected more firmly with achieving safety. A footplate on the bottom of the outer door can prevent people from being stumbled when people kick the door fence inattentively.

Description

The door hurdle

Technical field

The utility model relates to a kind of device that is used for doorway, stair mouth protection child safety, specifically a kind of hurdle.

Background technology

In order to protect child's safety, there is child's the family need be on the doorway or the door hurdle of a kind of safety effect of stair mouth device, to prevent forgetting that child causes danger at closing time.In the prior art, structure shown in Figure 5 is adopted in locking of door hurdle, and button drives by connecting rod and goes up the snap close activity, presses button and can open door.In the deadweight that can lean on door at closing time and the elastic force of spring door is retracted automatically, when shutting, last snap close and following snap close quilt be to pushing back at door, enter respectively at last in the groove of external door cross bar with following guide in, thereby reach the purpose of closing the door automatically.But, because the leverage of connecting rod is needing very big power just can push back snap close automatically at closing time, influence the effect of closing the door easily, even make it to lose efficacy.In addition, in order to adapt to the doorframe of different in width, door main body both sides, hurdle will install Yan Lan additional, add Yan Lan and install on the doorframe by the screw rod cover, but its ability of bearing external force is poor, gets loose easily, thereby have potential safety hazard.

Summary of the invention

It is time saving and energy saving that the technical problems to be solved in the utility model provides a kind of installation, door hurdle esy to use, safe and reliable.

The technical scheme that its technical problem that solves the utility model adopts is: a door hurdle external side of main body that is made of inside door and external door is provided with and adds Yan Lan, inside door is by in the top, the rotating shaft of extrinsic articulation and bottom is connected on the external door, the opposite side top with respect to rotating shaft of inside door is provided with locks, the bottom is provided with down lock, described locking by button, the button torsion spring, last snap close, the snap close support and the stage clip of locking constitute, lock to buckle and be provided with block, the stage clip of locking is arranged between block and the snap close support, last snap close one end stretches in the interior groove of external door, the portion of smashing of locking is provided with porose, the button bottom is provided with projection, the bottom of projection is the inclined-plane, and has in half hole of stretching into snap close.

Described inside and outside joint contacts by the inclined-plane, and intrinsic articulation links to each other by locating pin with extrinsic articulation, and the locating pin arranged outside has stage clip.

Described lock down is made up of following snap close and following lock tube, and following snap close lower end is stretched into down in the lock tube, and following snap close upper end is connected with steel wire, and the steel wire upper end is connected on the handle of locking.

Be provided with pipe close in the cross bar of the described Yan Lan of adding, pipe close links to each other by connecting rod.

The crossbar end of the described Yan Lan of adding is provided with the lengthening nut sleeve, and lengthening nut sleeve inboard is provided with the screw rod cover.

The bottom of described external door is provided with foot rest.

Door is opened,, used intrinsic articulation, extrinsic articulation to be free to slide, reach the purpose of closing the door on the inclined-plane by self gravitation.The elongated portion that adds the lengthening nut sleeve of Yan Lan end make nut sleeve can be in effective range its length of free adjustment, thereby more firm joining with doorframe reaches the purpose of safe handling.The foot rest of external door bottom can prevent that people from kicking on the hurdle because of carelessness and be tripped.
