Description
Technical field
The present invention relates to the KFC doors that KFC gate technique field more particularly to a kind of children can easily open.
Background technology
KFC door, industry slang are primarily adapted for use in hotel, market, office building, bank, coffee shop, showroom and fast food
The places such as shop, inside door, external door can be installed and used, and KFC door solves door during traditional aluminium alloy door and glass door use
Fan is easy the problem of sagging deflections or transposition, and the service life is longer, and long aluminium alloy extrusions uses special upset Widening Design, finished product
It assembles and is all fastened using stainless steel support, using the connection of aluminum alloy groove-shaped corner brace is thickeied, junction is adopted in door leaf corner
It is welded with high frequency argon arc aluminium, keeps more secured structure connection, the succinct smoothness of shock resistance KFC doors lines, modelling fashion graceful, be
The update of modern Commercial door is preferred.
Traditional KFC door is mainly made of doorframe, door leaf, door body glass, big knob, big hinge, door closer etc., but
It is when opening the door, to need certain strength, can be relatively difficult when child or old old man need to open KFC door, together
When, KFC door there are problems that pressing from both sides people when closing.
Invention content
The purpose of the present invention is to provide the KFC doors that a kind of children can easily open, to solve the above technical problems.
The present invention using following technical scheme in order to solve the above technical problems, realized：What a kind of children can easily open
KFC door, including door leaf, it is characterised in that：
By being hingedly connected on doorframe greatly, two corner of upper end of the door leaf is fixed by apical axis for the door leaf side
On doorframe, two corner of lower end of door leaf is installed on the ground by the earth's axis, and the door leaf includes left-hand door fan and right door leaf, institute
It states and opening aid is installed on the inside of the upper right side of left-hand door fan, opening aid is installed on the outside of the upper left side of the offside door, it is described to help out
Device includes pedestal, and the pedestal is fixedly mounted on doorframe, and rotating bar, the rotating bar are connected with by shaft on the pedestal
On telescopic putter is installed, the telescopic putter is provided with rubber perpendicular to rotating bar and doorframe, the free end of the telescopic putter
Rubber cushion is equipped with door closer, the centre position level peace of the left-hand door fan and right door leaf between the upper end and doorframe of the door leaf
Equipped with knob, the control switch of opening aid is provided with below the knob.It is the opening for the ease of door leaf that opening aid, which is arranged,
When children start control switch, shaft drives rotating bar rotation so that telescopic putter just contradicts on door leaf, then stretches
Push rod extends, and door leaf will be opened, and after door leaf is closed, rotating bar will rotate 180 degree, not influence door leaf in normal condition
Under either on or off, it then follows the principle on " right side go out into a left side ", so opening aid is equipped on the outside of the upper left side of offside door, in left-hand door
Opening aid is installed on the inside of the upper right side of fan.
Preferably, control switch is apart from 80 centimetres of ground.This height is suitble to the height that children can touch.
Preferably, the doorframe is spliced using high-strength aluminum alloy section, surface electrophoretic process.Improve KFC
The service life of door.
Preferably, the door closer includes head rod and the second connecting rod, and the head rod and second connect
Extension bar is connected by bull stick, and the side of the head rod is equipped with cylindrical sleeves, and positioning column, institute are provided in cylindrical sleeves
It states positioning column and is mounted on cylindrical sleeves inner bottom surface by incuding spring, second connecting rod is close to the side of head rod
It is arranged fluted, anti-pinch induction strip is vertically installed between left-hand door fan and right door leaf.It is to work as that anti-pinch induction strip, which is arranged,
When left-hand door is fanned and right door leaf clips to people, signal can be passed to induction spring, induction spring will bounce, will be in cylindrical sleeves
Positioning column bounces, and positioning column will be clipped between head rod and the second connecting rod, prevents the contraction of door closer, the setting of groove
Positioning column is pressed from both sides tighter, to prevent the closing of left-hand door fan and right door leaf.
Preferably, the positioning column can be sleeved on inside cylindrical sleeves completely, the cylindrical sleeves and head rod
Upper surface flush.Ensure that cylindrical sleeves and positioning column do not interfere with the work of door closer under normal circumstances.
Preferably, sand-proof hairbrush is installed, sand-proof hairbrush is fixed on rubber strip, the door below the door leaf
The lower end of fan is provided with the slot coordinated with rubber strip.Sand-proof hairbrush is directly anchored on rubber strip, ensure that door body is close
The setting of sealing property, slot makes rubber strip install and change conveniently.
The beneficial effects of the invention are as follows：
The setting that the present invention passes through opening aid so that children need to only press control switch, and door leaf will easily be opened,
When someone is accidentally clamped by door leaf, by the way that positioning column is arranged in the connecting rod of door closer, solves door leaf folder well
The event hurted sb.'s feelings occurs, the installation and removal of adhesive tape and sand-proof hairbrush entirety, ensures door body sealing performance, entire door body structure
Simply, practicability is high.
