Abstract
The invention belongs to the door lock field of buildings, and particularly relates to a rotary handle-free unlatched door lock, which comprises a lock body and a lock catch box, and is characterized in that: the lock body is provided with an asymmetric double-inclined-plane lock tongue, an oblique angle of an inclined plane of a tongue tip is 19 plus or minus 2 DEG, another oblique angle is 45 to 50 DEG, and the tongue tip of the double-inclined-plane lock tongue is deviated from the central plane; and the lock catch box is provided with a single-inclined-plane concave, and an oblique angle of the single inclined plane of the lock catch box is 20 plus or minus 2 DEG. Due to the adoption of the rotary handle-free unlatched door lock, the technical problems that the door can be opened or closed only by utilizing a push force or a pull force which is vertical to the door, and the indoor wind can be prevented from blowing away the door can be solved.
Description
Technical field:
The present invention is the door lock that belongs to building, especially about only can door be in the door lock of being left unlocked or unlatched of the handle without spin being left unlocked or unlatched and opening with a little slide force.
Background technology:
The improvement of living condition constantly enlarges floor space, and the door of cutting apart the room is also more and more many.The door lock in general indoor room only uses rotary handle or door knob dead bolt is stretched into or withdraws lock box, makes itself and keeper on the doorframe contact or take off and closes the door or open the door.What that is to say that indoor door lock often uses is to make door be in the function of the state of being left unlocked or unlatched, rather than with the real lock function of key.Though the door lock of indoor use often is in the state of being left unlocked or unlatched, also need rotate by hand after all handle or or door knob could realize being left unlocked or unlatched and closing and open of door.
Summary of the invention:
The object of the present invention is to provide a kind of door lock of being left unlocked or unlatched of handle without spin, solve and only use thrust vertical or pulling force to open the door or to close the door, and can prevent the technical problem that indoor wind-force blows door open with door.
The technical scheme that the present invention solves the problems of the technologies described above is:
Without spin handle be left unlocked or unlatched door lock, comprise lock body and keeper, it is characterized in that: this lock body is provided with asymmetric double inclined-plane dead bolt, the oblique angle on an inclined-plane of the tip of the tongue is 19 ± 2 °, another oblique angle is 45～55 °, the tip of the tongue of this double inclined plane dead bolt departs from central plane; This keeper is provided with monocline face depression, and the oblique angle of its monocline face is 20 ± 2 °.
Its inclined-plane of 45～55 ° of asymmetric double inclined-plane dead bolt mat of said structure of the present invention can be like a cork with dead bolt push-in door keeper.Deboost is bigger than the power of opening the door owing to 19 ° of inclined-planes with 20 ° cooperate, and does not feel effort again.This asymmetric double inclined-plane dead bolt length is greater than the double inclined plane dead bolt of symmetry simultaneously; Can reach more than 1.4 times of the latter; Even door and the bigger or fitful wind wind-force in doorframe gap are greater than the power of opening the door; But the time compole that continues of fitful wind is short, is not enough to dead bolt is released keeper fully, still can keep door to be in the state of being left unlocked or unlatched.
Beneficial effect of the present invention:
1. need not can door be left unlocked or unlatched or open with hand, can't operate when having avoided two hand held object and the awkward situation that can not enter the room.
2. save in the general door lock and the mechanism and the handle that use the key associated, simplified door latch structure greatly.Not only dwindle the volume of lock body, reduced material consumption, Production Time and carbon emission amount.
3. reduce the cutting workload of lock body installing hole, construction is convenient.
Description of drawings:
Fig. 1 is a three-dimensional appearance view of the present invention.
Fig. 2 is the perspective view that lock body unloads side cover.
Fig. 3 is the schematic cross section of dead bolt.
Fig. 4 is the keeper schematic cross section.
The specific embodiment:
The present invention is made up of lock body 1 and keeper 2 two parts (Fig. 1).Lock body 1 has the lock case 11 (Fig. 2) that embeds in the door; The panel 12 that is used for fixing lock case 11; Be connected the guide way 14 that in lock case 11, extends along lockhole on the panel 12 all around with panel 12 back sides; Be positioned at the limit journey piece 15 at dead bolt 13 rear portions, be fixed on limit journey pin 16 and spring supporting plate 17 on lock case 11 inwalls, be enclosed within the spring 19 on the expansion link 18 at dead bolt 13 rear portions, and with immersing oneself in the side cover 20 that plus screw 211 is connected with lock case 11.This dead bolt 13 is an asymmetric double inclined-plane dead bolt, and the oblique angle on an inclined-plane of the tip of the tongue is 19 ± 2 ° (Fig. 3), and another oblique angle is 45～55 °, and therefore the tip of the tongue departs from central plane X-X, and has enough length.This keeper 2 is provided with monocline face depression 21 (Fig. 4), and the oblique angle of its monocline face is 20 ± 2 °.
When dead bolt 13 and keeper 2 met, 45～55 ° inclined-plane on the dead bolt 13 just made easily and slips in the monocline face depression 21, shuts the door.If impose deboost or pulling force to door; On the dead bolt 13 in 19 ± 2 ° inclined-plane and the keeper 2 effect on 20 ± 2 ° of inclined-planes of monocline face depressions 21 can dead bolt 13 be skidded off this monocline face depression 21 door is opened; Just the power of opening the door is greater than door closing force, but can save the labor with hand operation.
Because non-title double inclined plane dead bolt 13 of the present invention has enough length, it skids off monocline face depression 21 needs the long period, so it can be resisted fitful wind door is blown open.
