Description
Technical field
The present invention relates to lock technology field, especially relate to a kind of automatic locking with rotation tapered end.
Background technology
At present, automatic locking has been widely used in security door to improve the anti-theft capability of security door.Conventionally, this automatic locking comprises housing, is articulated with lock core, the slip that can rotate and is provided with the slide plate that can slide up and down in this housing, and the upper end of this slide plate is fixed with dead bolt.That is, user drives this lock core rotation by turning the modes such as key, and this lock core drives this slide plate slides, and this dead bolt protrudes upward or retracts downwards then, realizes locking or opening of this automatic locking.Obviously, this dead bolt matches with the lockhole being positioned on doorframe.But, when there being lawless person crowbar to be stretched after the application of force between door core and doorframe, between this doorframe and door core, there will be gap, finally this security door is pried open., common automatic locking also exists pick-proof defect.
Summary of the invention
The object of this invention is to provide a kind of automatic locking with rotation tapered end, it has the feature of higher pick-proof ability.
The technical solution adopted in the present invention is: the automatic locking with rotation tapered end, comprise housing, in this housing, be articulated with the lock core that can rotate, slip is provided with the slide plate that can slide up and down, the upper end of this slide plate is fixed with dead bolt, described dead bolt has hollow cavity, in this hollow cavity, be penetrated with rotatable rotating handle, this rotating handle upper end is fixed with the jam plate perpendicular to this rotating handle, see from the top down, the width of this jam plate in warp-wise and broadwise is not identical, simultaneously, the lower end of this rotating handle is coaxially fixed with driven gear, and on this slide plate, slide and be provided with the horizontal tooth bar of left and right trend, this horizontal tooth bar links in this lock core.
Described horizontal tooth bar is provided with a movable block, and meanwhile, this housing is provided with a chute, and this chute has the vertical portion and the superposed rake that are positioned at bottom, and the end of this movable block is stuck in this chute.
On described lock core, be fixed with driving gear, limit, left side or the right edge of this slide plate are provided with vertical tooth bar, and this driving gear and this vertical tooth bar engagement.
The advantage that the present invention has is: have higher pick-proof ability.Of the present invention have rotation tapered end automatic locking in use, by the keyhole that can coordinate with jam plate is set on doorframe, this jam plate can enter in this keyhole, once and after this jam plate rotation, especially after 90 ° of rotations, this jam plate cannot from this keyhole out, even if crowbar is stretched between door core and doorframe, also be difficult to make prized gap between doorframe and door core, further increased the pick-proof ability of this security door.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that the automatic locking with rotation tapered end of embodiments of the invention is looked phantom drawing the master of locking state;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is that the automatic locking with rotation tapered end of embodiments of the invention is looked phantom drawing the master of open mode;
Fig. 4 is the top view of Fig. 3.
Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 to Fig. 4: have the automatic locking of rotation tapered end, comprise housing 10.In this housing 10, be articulated with lock core 20, the slip that can rotate and be provided with the slide plate 30 that can slide up and down, the upper end of this slide plate 30 is fixed with dead bolt 31.Further say, this dead bolt 31 has hollow cavity, is penetrated with rotatable rotating handle 40 in this hollow cavity.These rotating handle 40 upper ends are fixed with the jam plate 41 perpendicular to this rotating handle 40.See from the top down, the width of this jam plate 41 in warp-wise and broadwise is not identical., this jam plate 41 ovalizes or rectangle.Meanwhile, the lower end of this rotating handle 40 is coaxially fixed with driven gear 42, and slides and be provided with the horizontal tooth bar 50 of left and right trend on this slide plate 30, and this horizontal tooth bar 50 links in this lock core 20.Obviously, in use, the keyhole that doorframe is provided with and this jam plate 41 matches, this keyhole equally width in warp-wise and broadwise is not identical, thereby after stretching out, this jam plate 41 can enter in this keyhole, once and rotation, cannot from this keyhole out, thereby even if crowbar is stretched between door core and doorframe, be also difficult to make prized gap between doorframe and door core.Like this, after these lock core 20 rotations, drive this slide plate 20 to move and make this dead bolt 31 and this jam plate 41 stretch out or retract.Meanwhile, this lock core 20 drives these horizontal tooth bars 50 this driven gear 42 of rear drive that horizontally slips to rotate, and then makes this jam plate 41 produce rotation, reaches this jam plate 41 to be entered in the keyhole on doorframe or cannot be from effect out in this keyhole.
Aforementioned lateral tooth bar 50 links and can take the multiple common modes such as electric linkage in the mode of this lock core 20.Preferably, on this horizontal tooth bar 50, be provided with a movable block 60 by modes such as welding, such as, the bearing of trend of this movable block 60 is perpendicular to this slide plate 30.Meanwhile, this housing 10 is provided with a chute, and this chute has the vertical portion 71 and the superposed rake 72 that are positioned at bottom, and the end of this movable block 60 is stuck in this chute., this movable block 60 can slide in this chute.Like this, after this slide plate 30 slides up and down, this movable block 60 upper and lower translation simultaneously, then or be positioned at this vertical portion 71, or be positioned at this rake 72, and then make this horizontal tooth bar 50 produce the displacement on left and right directions simultaneously, finally this horizontal tooth bar 50 is stirred this driven gear 42.Such structure is very reliable and simple, and is easy to make this jam plate 41 to carry out accurately 90 ° of rotations.
Continue to optimize, on this lock core 20, be fixed with driving gear 21, the limit, left side of this slide plate 30 or right edge are provided with vertical tooth bar 32, and this driving gear 21 engages with this vertical tooth bar 32., this lock core 20 is driven by the parts such as key and after rotation, this driving gear 21 rotates, and then drives this slide plate 30 to slide up and down.Obviously, gear-driven mode is comparatively reliable.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
