Specific embodiment
With reference to the accompanying drawing, the embodiment of the present invention is discussed in detail.
Refering to fig. 1 to Fig. 4, the present invention provides a kind of twin-lock hook safety lock comprising the latch hook group being mounted in lock frame 1 Part and for drive hook locking component to act and complete locking with unlock driving assembly;
Below to hook locking component and driving assembly are described in detail respectively;
Driving assembly includes slide plate 4, driving motor 7, microswitch 9 and wiring board 11, and driving motor 7 and microswitch divide It is not electrically connected with wiring board 11, slide fit is equipped with bias in lock frame 1 to slide plate 4 on the output shaft of driving motor in the horizontal direction Wheel 8, which can stir slide plate and move right, specifically, opened up in slide plate upper end or lower end it is fluted, on the right side of the groove Side is equipped with the shifting block perpendicular to driver blade, and in actual production, which is formed by 90 degree of recess sidewall bending or weld assembly, Eccentric wheel is located in groove, and when stirring, eccentric wheel side wall is contacted with shifting block surface, to improve job stability and reliability;Make Used time, when eccentric wheel in a state of nature when, do not contacted with slide plate, microswitch is mounted on the motion path of slide plate, slide plate It moves to limit on the left position and triggers the microswitch;Specifically, a feeler lever is equipped on slide plate, when skateboarding to limit on the left position When, feeler lever triggers microswitch, and microswitch gives wiring board one signal, and wiring board makes driving motor stop operating.
Hook locking component is at least two groups, is two groups in the present embodiment, and be located at the groove two sides of slide plate;The hook locking component packet Latch hook ontology 2 and driver blade 3 are included, latch hook ontology 2 and driver blade 3 are rotatably mounted in lock frame 1, the angle of rotation of latch hook ontology Degree is more than or equal to 36 degree and less than or equal to 42 degree, in the unlocked state when latch hook ontology is clockwise to limes superiors position;When When latch hook ontology is rotated counterclockwise to limit inferior position, it is in locked state;The lock that can hook lock tongue 12 is offered on latch hook ontology 2 Slot, driver blade 3 connect with latch hook ontology 2 and can stir the rotation of latch hook ontology 2, meanwhile, latch hook ontology can also stir driver blade and turn Dynamic, connection structure includes a sliding slot and the pin shaft in the sliding slot, while being equipped with elastomeric element 5, this implementation in lock frame 1 Elastomeric element in example is tension spring, which connect with latch hook ontology 2, which have latch hook ontology to revolve clockwise The movement tendency turned, while torsional spring 6 being installed in lock frame 1, the head (right end) of torsional spring is connect with lock frame 1, the tail portion of torsional spring (left end) forms the grab that can catch on driver blade to side bending, and the end of grab is inserted in the strip groove to slide plate, this The length direction of shape slot is parallel to the glide direction of slide plate, when slide plate moves right, stretchy grab (i.e. torsional spring left end) to It moves right, to make grab and driver blade be detached from, while the torsional spring makes slide plate have the movement tendency slided to the left;Specifically, The side wall of driver blade offers the first groove 21 and second groove 22 that can catch on torsional spring, first groove and the second groove it Between by arcwall face connect, when driver blade is in limes superiors position (locking state), torsional spring is stuck in first groove;Work as driver blade When in limit inferior position, torsional spring is stuck in second groove;In order to can smoothly unlock in the power-off state, further include in the present embodiment One emergent unlocking device, the emergent unlocking device include the core of emergency lock 13 being fixed on lock frame 1 and connect with core of emergency lock Emergency lock plectrum 10, core of emergency lock can drive emergency lock plectrum rotation, meanwhile, emergency lock plectrum connect with driver blade and can stir The slide plate slides;The limiting device for limiting slide plate left and right stroke (limit), limit dress are equipped on slide plate or lock frame It is set to limiting slot and/or retention bead.
The working principle of twin-lock hook safety lock of the present invention is illustrated below;
At closing time, lock tongue 12 presses down with moveable lock hook ontology 2 and rotates counterclockwise it, while latch hook ontology drives transmission Piece rotates counterclockwise, when latch hook ontology rotate counterclockwise to (under) limit position when, torsional spring clasps driver blade and makes 2 nothing of latch hook ontology Method is rotated further by, and completes to lock a door;
When electric open-door, by button on door or remote-transmitter opening signal to wiring board 11, wiring board 11 is to driving Motor signal, driving motor band movable eccentric wheel rotate, and eccentric wheel turns dynamic and slide plate is driven to slide to the right, while driving torsional spring (left end grab) moves right, and is detached from the groove on the grab and driver blade on torsional spring, at this time work of the latch hook ontology in tension spring Be clockwise under (on) limit position, it completes to unlock;And work as eccentric wheel and return to origin, it (is eccentric under usual situation origin The maximum distance of wheel surface and slide plate shifting block) when, i.e., it is contactless between eccentric wheel and slide plate, under the action of the torsion spring, slide plate It moves downward to limit on the left position, until triggering microswitch, which, which switchs, gives wiring board one signal, stops driving motor Rotation.
When opening Door by Hand, when emergency key, which rotates, drives emergency lock plectrum, driving slide plate is slided to the right, drives torsional spring (left end grab) moves right, and is detached from the groove on the grab and driver blade on torsional spring, latch hook ontology is under the action of tension spring Be clockwise to (on) limit position, it realizes and unlocks.
Twin-lock hook safety lock twin-lock hook of the present invention, improves a lot for safety.Can latch lock automatically at closing time Firmly door, motor automatic door opening, emergency key open Door by Hand.
Twin-lock hook safety lock of the present invention, simple and compact for structure, manufacturing cost is low, and using double shackle designs, safety coefficient is high, It can complete to latch automatically at closing time;It is opened the door using electronic with emergency key, stability is good.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications Also it should be regarded as protection scope of the present invention.
