The specific embodiment
Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 the utility model is done further description:
The described escape door release mechanism of the utility model comprises push rod 2, lock core 8, last retaining mechanism, following retaining mechanism, linkage, stopping means 11 and back-moving spring 10.
For conveniently using and operate, and consider that most of user's height, push rod 2 laterally are connected the middle part of escape door 1, realize the unlatching of release mechanism in the escape door 1 with the mode of upper and lower promotion.Wherein, push rod 2 one ends are provided with rocking arm 13, and rocking arm 13 is provided with bearing pin 14, and bearing pin 14 is directly had an effect with following retaining mechanism as the connector of retaining mechanism under promoting, and control escape door 1 in case of emergency can be opened fast.
Upper and lower retaining mechanism vertically is connected the inboard of emergency door release end; And through linkage realization connection transmission synchronously; The outer end of upper and lower retaining mechanism is locked on the doorframe with the top and the bottom of inserting mode with escape door 1, has guaranteed that escape door 1 closes closely.Wherein, last retaining mechanism comprises guide holder 16 and last locking bar 3, and last guide holder 16 is fixed on the position of emergency door release end inboard near the top, and after last locking bar 3 passed guide holder 16, the bottom of last locking bar 3 was connected with bindiny mechanism.Last guide holder 16 can effectively guarantee the direction that moves both vertically of locking bar 3, improves the accuracy of motion process.Stopping means 11 is fixed on the inside top of emergency door release end, and matches with the end of last locking bar 3, and the boom end that prevents to lock is opened incomplete phenomena.Back-moving spring 10 is enclosed within on the locking bar 3, and the top of back-moving spring 10 withstands on the located lateral pin of locking bar 3, and the bottom is fixed on the guide holder 16, and back-moving spring 10 is used to promote locking bar 3 and easily resets.Following retaining mechanism comprises guide holder, following locking bar 4, bottom plate 9 and mounting plate 15 down.Locking bar 4 moved under mounting plate 15 and bottom plate 9 were mainly used in and drive, thereby opened escape door 1.Mounting plate 15 is separately fixed at down on the bar wall of locking bar 4 with bottom plate 9; Lock core 8 is fixed on the escape door 1; The dead bolt 12 of lock core 8 is corresponding with mounting plate 15 bottoms; the bearing pin 14 on the rocking arm 13 is corresponding with the bottom of bottom plate 9, through dead bolt 12 or bearing pin 14 upper and lower to move, drive mounting plate 15, bottom plate 9 and down locking bar 4 in movement in vertical direction.Following guide holder is fixed on the position of emergency door release end inboard near the bottom, and after following locking bar 4 passed down guide holder, its top was connected with bindiny mechanism.
Linkage comprises supporting seat 5, and a synchronizing bar 7 and two connecting rods 6 of being positioned at supporting seat 5, and bindiny mechanism is responsible for last retaining mechanism and following retaining mechanism are connected, and guarantees that two mechanisms can be synchronized with the movement.Wherein, Supporting seat 5 is fixed on the inboard of emergency door release end; Synchronizing bar 7 is connected on the supporting seat 5 through axle, and two connecting rods 6 are connected to the two ends of synchronizing bar 7, and two connecting rods 6 can be done respectively upwards and are synchronized with the movement downwards along with the rotation of synchronizing bar 7; The outer end correspondence of two connecting rods 6 is connected the last locking bar 3 that passes supporting seat 5 and the end of following locking bar 4, and locking bar 3 and following locking bar 4 are synchronized with the movement in the drive.
When escape door 1 was closed, last locking bar 3 was plugged in the jack of doorframe with following locking bar 4 correspondences, guaranteed escape door 1 locking.When running into accident and need emergency opening, a kind of mode is: the people is for depressing push rod 2, through rocking arm 13 rotations of push rod 2 one ends; The bearing pin 14 that drive is fixed on the rocking arm 13 promotes bottom plate 9 risings, and guide holder lifts under locking bar 4 edges thereby make down, simultaneously; Rotation through connecting rod 6 transmissions and synchronizing bar 7; Locking bar 3 moves downward synchronously in the drive, and the masthead end of locking withdraws from from the doorframe jack, accomplishes the escape door emergency opening.Last locking bar 3 after the unlatching receives the effect of stopping means 11, and rod end is stuck in the stopping means 11, can not expose in the outside of escape door 1, has guaranteed that the switch of escape door 1 is smooth and easy.Recover elastic force and go up the back-moving spring 10 in the guide holder 16 owing to be compressed generation; Can produce a thrust that makes progress to last locking bar 3; But the influence of drawn stem rocking arm 13 and bearing pin 14 supporting roles, restoring force can not boost going up locking bar 3, so escape door 1 can rotate freely, open.When needs are closed escape door 1, upwards lift push rod 2 through manpower, eliminate the support force of rocking arm 13 and 14 pairs of bottom plates 9 of bearing pin; Upper and lower locking bar 3,4 is under the effect of back-moving spring 10 elastic force, along with the Synchronous Transmission of connecting rod 6 and synchronizing bar 7; Respectively with upper and lower locking bar 3; 4 upwards with downwards release, accomplish upper and lower to locking, escape door 1 is closed.Another kind of mode is: carry out escape door 1 with key and open; Its mode is basic similar with first kind of mode, just when opening, through dead bolt 12 rotation touching mounting plates 15 bottoms; Utilize the rotation of dead bolt 12 to move to drive mounting plate 15 and lift, thereby accomplish the process of opening escape door 1.Whole process, bearing pin 14 is positioned at the below of bottom plate 9 all the time, thus can not influence the opening process of dead bolt 12, thus the reliable use of two cover emergency opening modes guaranteed.
