Technical Field

The invention relates to the technical field of household fence doors, in particular to a door fence convenient to open and close.

Technical Field

the children like to know fresh things in the development period, but because the children are in unknown stages for dangerous behaviors or the cognition of dangerous things, the children are easy to run at home to cause unnecessary injury to the children, and at present, parents are busy or even rest at home and need to be busy for housework, so that the children cannot be cared for at any moment, the household fence can well limit the activity area of the children, and the children are separated from the dangerous area.

Most of the related domestic doorfences in the market are mainly safe, and the convenience of door lock operation is sacrificed on the premise of ensuring safety in many times.

Disclosure of Invention

the invention aims to solve the problems and provides a door sill which is provided with a novel door lock opening and closing mode, so that the design of a door lock on the basis of safety is more in line with human engineering, the operation is more comfortable, and the opening and closing are more rapid and convenient.

The utility model provides a convenient door sill opens and shuts, include the door leaf and with door leaf looks articulated door frame still includes:

the upper door lock part consists of an upper door lock positioned at one end of the upper part of the door leaf and an upper lock seat positioned on the door frame and corresponding to the upper door lock, and the upper door lock is locked with the upper lock seat through an upper lock tongue and realizes the locking and unlocking of the upper lock tongue and the upper lock seat through a pressing and holding transmission structure;

The lower door lock part consists of a lower door lock positioned at one end of the lower part of the door leaf and a lower lock seat positioned on the door frame and corresponding to the lower door lock, wherein a lower lock tongue is arranged on the lower door lock, and the lower lock tongue realizes locking and unlocking through relative up-and-down movement between the lower lock tongue and the lower lock seat;

The hinge part consists of a door leaf hinge positioned on one side of the door leaf and a door frame hinge positioned on the door frame and corresponding to the door leaf hinge, and the door leaf hinge is hinged with the door frame hinge.

preferably, the pressing and holding transmission structure comprises a pressing piece positioned at the upper part of the upper door lock, a holding piece positioned at the lower part of the upper door lock, a first linkage piece for linking the pressing piece and the holding piece, and a second linkage piece for linking the holding piece and the upper lock tongue;

The first linkage piece is hinged in the upper door lock through a hinge shaft in the middle of the first linkage piece, one end of the first linkage piece is a pressing end and rotates around the hinge shaft as the center of a circle along with the pressing of the pressing piece, the other end of the first linkage piece is a holding piece limiting end, the first linkage piece limits the vertical displacement of the first linkage piece through abutting against the holding piece, the holding piece limiting end rotates around the hinge shaft as the center of a circle under the driving of the pressing end, and when the pressing piece presses downwards, the rotating motion of the holding piece limiting end enables the holding piece limiting end to be separated from the abutting position of the holding piece, so that the limiting effect on the holding piece is relieved;

one end of the second linkage piece is fixedly connected with the holding piece, the other end of the second linkage piece is provided with a lock tongue guide pillar, a guide pillar access channel for the lock tongue guide pillar to access is arranged in the upper lock tongue, a guide pillar clamping portion is arranged at one end of the guide pillar access channel, and when the lock tongue guide pillar moves upwards in the guide pillar access channel, the upper lock tongue extends out and retracts through contact with the guide pillar clamping portion.

Through adopting above-mentioned technical scheme, hold when the press key is in original state and carry the piece because can not carry out vertical displacement by the restriction of contradicting, consequently unblank and need two steps of unblocks, reduced the possibility that children unblanked, but the adult only needs one hand to hold just can realize unblanking.

Preferably, the bolt guide post is obliquely arranged, and the horizontal distance between the lower end of the bolt guide post and the holding piece is smaller than the horizontal distance between the upper end of the bolt guide post and the holding piece. Thereby realizing the vertical movement and the transverse movement.

preferably, the lower part of the pressing piece, the upper part of the holding piece and one end of the upper lock tongue extending into the upper door lock are both provided with a resetting piece, and the resetting piece enables the three parts to return to the original positions when being free from external force. The automatic reset is realized, and special manual operation is not needed to reset, so that the automatic reset is convenient and fast.

Preferably, a lower lock tongue limiting groove extending in the vertical direction is formed in the lower lock base, and an opening for the lower lock tongue to be clamped into is formed in the upper end of the lower lock tongue limiting groove. The fixing device is used for limiting the position of the lower end of the door leaf and has a fixing effect.

Preferably, a buffer piece is arranged at one end of the lower lock tongue extending into the lower door lock, and the buffer piece enables the lower lock tongue to stretch out and draw back when colliding with the lower lock seat; when the lower lock tongue reaches the position of the lower lock tongue limiting groove, the elastic potential energy of the lower lock tongue is released, and the lower lock tongue is popped out to enter the lower lock tongue limiting groove to complete locking.

Through adopting above-mentioned technical scheme, make down the spring bolt with produce elastic collision when the lock seat collision down, lower spring bolt is through collision and resilience automatic entering lower lock, and the action that need carry when removing the door from and closing the door makes the operation more convenient. Preferably, the lower door lock is located at the lower end of the door leaf and is in plug-in connection through a rod piece, and the lower door lock and the rod piece are fixed through a nut screw. Due to the double fixing mode, the lower door lock is more firmly fixed.

Preferably, the lower lock base is fixed to the lower end of the door frame by screws and nuts.

Preferably, the hinge is located at an upper end of the door sill.

Preferably, a lifting allowance space is arranged between the door leaf hinge and the door frame hinge and used for accommodating the door leaf hinge lifted upwards. The lifting allowance space enables the lower lock tongue to be lifted out of the lower lock base more easily.

The invention has the following advantages: the design of going up the lock more accords with human engineering, and the adult is more comfortable when the operation, only needs to hold and carry two actions and can accomplish the unblock, and the design of lock also satisfies the prerequisite of safety, and is also comparatively convenient when opening and shutting.
