Description
Technical field
The present invention relates to a kind of baby safety protection field more particularly to safety door guardrail, be for being installed on stairs port,
It drops on stair, causes danger when child being avoided to be at play.
Background technique
Preschool child is in study and ability to model strongest stage, so, the children curiosity in this stage and
Energy is also the most vigorous, especially in the child in the stage of learning to walk, due to just standing and walking in study, so walking always
Totteringly, be not able to maintain good center of gravity still, thus the furniture for being easy to bump against in family and it is injured, especially at stair
It falls, that consequence is really hardly imaginable.But we and child can not be looked at anywhere or anytime, so on the market just there are many specially
For the structure that child designs, such as go-cart, infanette, allow child that can be sitting in go-cart movable foot, or baby with
In bed, to avoid child runs about and causes danger, still, those structures can allow the space of children's activity very small, this is right
It, will soon be noisy because of feeling uneasy for the just vigorous child of energy.Based on the above background, there is safety door in the market
Guardrail is used to be mounted on doorframe or stairs port, keeps child movable in a restricted area, far from danger zone.Currently,
The class opening structure that relatively conventional safety door guardrail uses in the market, one end of guardrail is hinged, and the other end can buckle fixation；It is suitable
For rotating guardrail along its hinged end, opening and closing is realized.But above-mentioned safety door guardrail occupied space is larger, is had not using also more
Just.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of safety door guardrail, which is compared
In the safety door guardrail of existing class opening structure, the program, which has, to occupy little space, advantage easy to operate.
In order to achieve the above purpose, present invention employs technical solutions below:
A kind of safety door guardrail, including reels mechanism and drop in beam；The reels mechanism includes that spool and inner end are connected to spool
On guardrail cloth, and the rotation of the driving spool realizes the reset assembly of winding guardrail cloth, and the limitation spool rotation
The limit assembly turned；When the guardrail cloth is in unfolded state, outer end can be clamped with the drop in beam and connect；The limit group
Part includes limiting component, and limiting component can be axially moved with respect to spool, and the circumferential direction of limiting component is limited；The limiting component
Axial movement path in include the locking position circumferentially linked with spool, and the solution lock-bit being separated with the spool.
Preferably, the limit assembly includes first shell, the inside of first shell is equipped with and limiting component section phase
The axis hole of adaptation；The limiting component is in axis hole, and can be moved along the axial direction of axis hole, the limitation limit of axis hole side wall
