The specific embodiment
Below in conjunction with the drawings and specific embodiments technology contents of the present utility model is elaborated.
Sound insulating door lock as depicted in figs. 1 and 2 comprises lock box 1 and keeper 6, is provided with turbine dead bolt 2 in the lock box 1, is provided with the groove that cooperates with turbine dead bolt 2 in the keeper 6.The centre of turbine dead bolt 2 be provided with can be held into square key 7 polygonal hole 13(referring to Fig. 3), handle 3 is connected with polygonal hole by square key 7 and is connected with turbine dead bolt 2, and 2 rotations of drive turbine dead bolt.
In conjunction with Fig. 2, Fig. 3 and Fig. 4 as can be known, turbine dead bolt 2 has dead bolt mesh regional 4 and self-locking zone 5.Dead bolt mesh regional 4 has the low-angle inclined-plane in vertical direction with certain angle of inclination, and the grooves in the keeper 6 have the surface of action identical with the angle of inclination on the low-angle inclined-plane of dead bolt mesh regional 4.The scope at this angle of inclination take less than 10 ° as good, more preferably, can between 5 °～8 °, select.Self-locking zone 5 has the vertical field of conjugate action.By the engagement of dead bolt mesh regional 4, self-locking zone 5 and keeper 6 inner groovies, realize the soundproof effect of sound insulating door lock.
As shown in Figure 2, in lock box 1, the below of turbine dead bolt 2 is provided with dead bolt locking device 8, dead bolt locking device 8 has the lockhole that inserts rotation for key, and the hook portion that moves with key turns, this hook portion is used for and the groove fit that is arranged on the turbine dead bolt 2, the position of locking turbine dead bolt 2.Prescribe a time limit when turbine dead bolt 2 arrives under the self-locking position, the groove of turbine dead bolt 2 contacts with the hook portion of dead bolt locking device 8, and dead bolt locking device 8 can move, thereby, prevent that the external world from carrying out faulty operation by handle 3.
With reference to Fig. 5 and Fig. 6, keeper 6 is installed on left-hand door fan (the perhaps doorframe) 9, lock box 1 is installed on the right door leaf 12, and (that is, the outside in the door leaf) is separately installed with handle 3 in lock box 1 both sides.Between two door leafs or door leaf and doorframe, be provided with sealing joint strip.When door leaf cut out, it was closed to drive door leaf by handle 3.When the mesh inclined plane of dead bolt mesh regional 4 during near keeper 6, rotate counterclockwise handle 3, make dead bolt mesh regional 4 and keeper 6 engagements, this moment, door leaf touched sealing joint strip, keeper 6 and 2 engagements of turbine dead bolt.When dead bolt mesh regional 4 and keeper 6 are engaged to down in limited time, turbine dead bolt 2 and keeper 6 self-lockings, door leaf is compressed to the position shown in 10 with sealing joint strip position of 11 from Fig. 6, plays sealing effectiveness, and the interference of stopping the external world enters indoor.At this moment, the groove fit on the hook portion of dead bolt locking device 8 and the turbine dead bolt 2, locking turbine dead bolt 2 prevents that the external world from carrying out faulty operation by handle 3.Outside door leaf, can make bolt lock decide device 8 actions by key, then can make 8 actions of dead bolt locking device by knob in the door leaf inboard, remove the locking action of 8 pairs of turbine dead bolts 2 of dead bolt locking device.
When door leaf was opened, door leaf is outer to make 8 actions of dead bolt locking device by key, first the dead bolt locking device 8 of turbine dead bolt 2 is opened.For handled easily, the outside is equipped with handle 3 in the door leaf, and pulling handle 3 drive turbine dead bolts 2 clockwise rotate door leaf is separated with doorframe, then, relies on the deadweight of turbine dead bolt 2 to make handle 3 be rotated counterclockwise 90 degree, recovers the position.At this moment, sealing joint strip restores to the original state, and door leaf is opened.
The sound insulating door lock that the utility model provides is installed on the soundproof door, by the mesh inclined plane of turbine dead bolt in the lock box, compress gradually with the groove that is arranged in the keeper, so that be arranged between the door leaf or frame fan between sealing joint strip enough distortion are arranged, guarantee sealing, reach soundproof effect.This sound insulating door lock is simple in structure, be easy to processing and manufacturing, and cost is low, and is easy and simple to handle, and this sound insulating door lock has the function passed through of blocking-up sound, in the service depot, the places such as conference room, cinema install, but the Effective Raise soundproof effect is applicable to be widely used in the higher place of sound isolation requirement.
The above has been described in detail sound insulating door lock provided by the utility model.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from the utility model connotation it being done all will consist of the utility model infringement of patent right, will bear corresponding legal liabilities.
