Locking to tamper baffle plate 4.
Specifically, the tamper swing rod 5 is V-shaped, including the first arm 51 and the second arm 52 set in angle, the rotating shaft
53 are arranged on the point of intersection of the arm 52 of the first arm 51 and second, and first arm 51 props up the top of the tapered end 2, and described
Two arms 52 prop up the tamper baffle plate 4, and this tamper swing rod structure is simply easily installed.
Specifically, the latch-up structure is additionally included in automatic lock and completed the relatively described lock of the tamper swing rod 5 before installing
The locking of shell 1 makes the tamper baffle plate 4 be maintained at the non-locked component for propping up position, is put the tamper by locked component
Bar 5 is fixed on the top of the tapered end 2, and tamper swing rod 5 is locked, and can prevent before tapered end 2 is not installed, and tamper swing rod 5 exists
Rotated in the presence of torsion spring, disturb the installation of other structures, and by locking piece from lock box side after lockset installation
It can be achieved to make dead bolt locked function after tapered end is removed or is destroyed after dismounting.
Specifically, the locked component includes the through hole for being molded on the tamper swing rod 5, is molded over the lock housing 1
Screwed hole on bottom plate or cover plate, and the screw 8 being threadedly coupled is realized through the through hole, the screwed hole, using screw
It is threadedly coupled easy disassembly.
Specifically, the tamper baffle plate 4 includes bottom plate 43, and is vertically set on the biside plate at the both ends of bottom plate 43,
The first side plate 41 in two side plates the tamper baffle plate 4 be moved to it is described prop up position when, prop up the spring bolt mechanism
3, the biasing member is acted on the second side plate 42 in two side plates, and the biasing member can drive second side plate
42 vertically move, so that vertically movement makes first side plate 41 prop up the lock to first side plate 41
Tongue mechanism 3, plays anti-theft function.
Specifically, the length of first side plate 41 is more than the length of second side plate 42, can make first side
Plate 41 props up the spring bolt mechanism in time, dead bolt retraction is opened door lock by stirring unlock piece after preventing tapered end destroyed.
Specifically, the biasing member is torsion spring 6, and the torsion spring 6 is set in the rotating shaft 53, the of the torsion spring 53
One torsion spring pin 61 is fixedly connected with the lock housing 1, and the pin of the second torsion spring pin 62 props up the tamper baffle plate 4 and set, 6 sets of the torsion spring
It is located in the rotating shaft 53, when tamper swing rod 5 rotates torsion spring 6 can be driven to rotate, it is compact-sized, it is easy for installation.
Specifically, in order to ensure tamper baffle plate 4 in the presence of torsion spring 6, accurately it can prop up position and non-prop up
Moved between position, in addition to the guide frame that the movement to the tamper baffle plate 4 is oriented to.
Specifically, the guide frame includes at least one groove 7 being molded on the bottom plate or cover plate of the lock housing 1,
And be arranged on the tamper baffle plate 4 be suitably inserted into the groove 7 at least one raised 44, and the groove 7
Length props up the distance between position not less than the non-position that props up to described, and the groove 7 can limit the tamper baffle plate
Movement in the horizontal direction, and make the tamper baffle plate along with the dead bolt lock out or direction that retracted orientation is vertical is moved
It is dynamic.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
