Description

Anti-collision door handle

Technical field

The present invention relates to a kind of catch, especially anti-collision door handle.

Background technique

Currently, catch not only protrudes from the front and back door-plate of dodge gate, and catch is more sharp, be easy to damage in The children that dodge gate is played, it is a kind of that catch is avoided to damage the anti-collision door handle of children, it has also become catch is avoided to damage children Needs.

Summary of the invention

The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of anti-collision door handle, catch is avoided to damage Children.

The technical scheme adopted by the invention is that：Anti-collision door handle include bolt apparatus, concealed installation handle apparatus and Lock core device, bolt apparatus are connect with concealed installation handle apparatus and lock core device；Bolt apparatus include keeper, bolt set, spring, Trussed shore, outer rack gear, inner rack and lock tongue, keeper and the dynamic mating connection of bolt set, spring are located in bolt set, and spring pocket is being drawn Outside column, keeper is connect with trussed shore, and trussed shore is connect with outer rack gear and inner rack, and lock tongue is connect with trussed shore；Concealed installation knob Device includes that outer knob, outer notch board, interior knob and interior notch board, outer notch board and interior notch board are fixedly connected with dodge gate；Outside Knob is equipped with external gear and outer shaft, and outer knob is hinged by outer shaft and outer notch board, and external gear is coaxially connected with outer shaft, External gear is engaged with the outer rack gear of bolt apparatus；It is interior knob be equipped with internal gear and interior shaft, it is interior knob by interior shaft with it is interior Notch board is hinged, and internal gear and interior shaft are coaxially connected, and internal gear is engaged with the inner rack of bolt apparatus；It is living when dodge gate is closed Dynamic door and doorframe are in closed state, and the keeper of bolt apparatus is inserted into the locking bolt hole of doorframe under the effect of spring force；It opens When dodge gate, drive keeper mobile by external gear using outer knob, alternatively, driving keeper to move by internal gear using interior knob It is dynamic, so that keeper is exited the locking bolt hole of doorframe, opens dodge gate；Lock core device includes lock core, sliding chute seat and sliding jam plate, is slided Groove seat is fixedly connected with dodge gate, and the locked groove for sliding jam plate is located at the lower section of lock tongue, and lock tongue is against locked groove；Use key rotation lock core When locking, sliding jam plate rises, and the locked groove for sliding jam plate snaps onto the position of lock tongue, keeps keeper immovable；At the beginning of bolt apparatus Beginning state is：Keeper is stretching state, and keeper stretches out in the bolt hole of bolt set under the effect of spring force, and spring is compression bullet Spring；In order to avoid outer knob and interior knob injure human body, concealed installation handle apparatus original state is：Bullet of the outer rack gear by spring Power traction, outer knob are drawn by outer rack gear, are inserted into the outer knob edge of outer knob in the external groove of outer notch board, keep human body difficult To collide the outer outer knob edge shaken hands；Elastic traction of the inner rack by spring, interior knob are drawn by inner rack, make interior drawing The interior knob edge of hand is inserted into the inner groovy of interior notch board, and human body is made to be difficult to collide the interior knob edge of interior knob.

The application method of anti-collision door handle is：When dodge gate by opening outdoors, hand grabs outer knob, and outer knob is drawn to swing, The outer shaft and external gear of outer knob follow the swing of outer knob and rotate, and external gear drives the outer rack gear of bolt apparatus to move Dynamic, outer rack gear draws keeper movement by trussed shore, and keeper is made to exit the locking bolt hole of doorframe, opens dodge gate；By closing outdoors When dodge gate, hand grabs outer knob and draws dodge gate to be swung to doorframe, and when the locking bolt orifice plate of keeper and doorframe contacts, doorframe overcomes gram The elastic force pressure gate bolt for taking spring is mobile, and when dodge gate is closed, keeper is directed at the locking bolt hole of doorframe, and hand loosens outer knob, keeper Enter the locking bolt hole of doorframe in the elastic force effect underthrust of spring, dodge gate is closed；When dodge gate in door by opening, hand grabs interior knob, Knob is swung in drawing, and for the interior shaft of interior knob with internal gear follows the swing of interior knob and rotates, internal gear drives bolt apparatus Inner rack it is mobile, it is mobile that inner rack by trussed shore draws keeper, so that keeper is exited the locking bolt hole of doorframe, opens dodge gate； When by closing dodge gate in door, hand is grabbed interior knob traction dodge gate and is swung to doorframe, when the locking bolt orifice plate of keeper and doorframe contacts, Doorframe overcomes the elastic force pressure gate bolt of spring mobile, and when dodge gate is closed, keeper is directed at the locking bolt hole of doorframe, and hand loosens interior Knob, keeper enter the locking bolt hole of doorframe in the elastic force effect underthrust of spring, and dodge gate is closed；When dodge gate is locked, key is utilized Lock core is rotated, lock core drives sliding jam plate to rise, and the locked groove for sliding jam plate snaps onto the position of lock tongue, keeps keeper immovable； When dodge gate is unlocked, using key rotation lock core, lock core drives sliding jam plate decline, and the locked groove for sliding jam plate exits the position of lock tongue It sets, keeper is enable to move.

The beneficial effects of the invention are as follows：Anti-collision door handle includes bolt apparatus, concealed installation handle apparatus and lock core dress It sets, bolt apparatus is connect with concealed installation handle apparatus and lock core device；Bolt apparatus include outer rack gear, inner rack, spring with And keeper, concealed installation handle apparatus include outer knob, outer notch board, interior knob and interior notch board, outer knob includes external gear, interior Knob includes internal gear；In use, pulling outer knob or interior knob when opening dodge gate, passing through external gear and external tooth Item or internal gear and inner rack traction keeper overcome the elastic force of spring mobile, and keeper is made to exit the locking bolt hole of doorframe；It closes When dodge gate, hand decontrols outer knob or interior knob, and keeper reset movement under the effect of spring force makes keeper be inserted into doorframe Locking bolt hole；Outer knob edge is embedded in outer notch board, and outer knob corner is arc, and interior knob edge is embedded in interior notch board, interior drawing Angle is arc on hand, and outer knob and interior knob is avoided to injure human body, especially children.
