Description
Technical field
The utility model relates to lock technology field, is specifically related to a kind of mechanical lock with function of anti-prizing.
Background technology
At present, the mechanical cage knob of known electrical anti-error lock has pellet cage knob and the large class of yi word pattern cage knob two.Pellet cage knob comprises single row or multiple rows pellet, and then is evolved into the forms such as atomic lock and Plum blossom type lock.Flexibly, anti-theft grade is high for inner each pellet motion of this type of lockset, and lockset and key precision-fit are high to the requirement on machining accuracy of lockset and key.But the joining of power industry, power transmission station are mostly in area remote or that environment is more severe, especially out of doors, corrosion and dust are normal to be corroded to cage knob, and pellet is often subjected to displacement and volumetric change, cause lockset generation bite and the phenomenon of not opening, and then cause emergent accident to process and incur loss through delay.
The lockset of yi word pattern cage knob coordinates the form of pull-preventing pin, and principle is simple, easy to process, even when cage knob exists a small amount of corrosion and dust, also can open lockset by external force.As shown in Figures 1 and 2, the lockset of current yi word pattern cage knob comprises lock body 1, locking bar 2, dead bolt 3, cage knob 4, latch bolt spring 5, unblank spring 6 and pull-preventing pin 7.Dead bolt 3 is located in the lock tongue slot of lock body 1 movably, and its downside outer rim is provided with groove 31, and right-hand member is provided with Breech block 32.Cage knob 4 upper ends are departed from its axis of rotation heart and are established a shifting block 41, and lower end is provided with interlock boss 42.Locking bar 2 is arranged in the locking bar groove of lock body 1, and the Breech block 32 by dead bolt 3 right-hand members is stuck in its breach 21 and realizes locking.Cage knob 4 is located in the unlock hole on lock body 1 rotationally, and its shifting block 41 inserts the groove 31 of dead bolt 3.Latch bolt spring 5 is located at the left side of lock tongue slot, supports the left part of dead bolt 3.The spring 6 of unblanking is located at the downside of locking bar groove, supports the bottom of locking bar 2.Pull-preventing pin 7 is located at the lower end of unlock hole.The end of key 8 is provided with the interlock groove 81 mating with interlock boss 42.
During release, the unlock hole that key 8 inserts on lock body 1, interlock groove 81 and 42 interlocks of interlock boss, screw key 8, the shifting block 41 of cage knob 4 upper ends drives dead bolt 3 to left movement, thereby makes the breach 21 of the Breech block 32 disengaging locking bars 2 of dead bolt 3 right-hand members, under the effect of the spring 6 of unblanking, realizes release.During locking, key 8 rotates backward and drives cage knob 4 to reset, and dead bolt 3 makes dead bolt 3 move right under the effect of latch bolt spring 5, and the Breech block 32 of right-hand member is stuck in the breach 21 of locking bar 2 and realizes locking.
Because the current cross section of the interlock boss 42 of cage knob 4 lower ends mostly is the symmetric figures such as in-line, rectangle or hexagon, longitudinal section is rectangle, and boss is directly connected with cage knob main body, utilizes common tool that it is prized or is stirred, be easy to open lockset, make electrical anti-error disabler.
Utility model content
The utility model object is to provide a kind of and prevents from utilizing common tool it to be prized or is stirred the mechanical lock with function of anti-prizing with illegal release.
Above-mentioned purpose is achieved through the following technical solutions:
A mechanical lock with function of anti-prizing, comprises cage knob, and described cage knob lower end is provided with interlock boss, it is characterized in that: the cross section of described interlock boss is asymmetric polygon.
As concrete technical scheme, the cross section of described interlock boss is equilateral triangle or regular pentagon.
As further technical scheme, the longitudinal section of described interlock boss is inverted trapezoidal wide at the top and narrow at the bottom.
As further technical scheme, described interlock boss is connected with cage knob main body by a neck, and the radial dimension of described neck is less than the radial dimension of described interlock boss upper end.
As further technical scheme, the intersection of the adjacent side of described interlock boss is provided with chamfering.
As concrete technical scheme, described chamfering is fillet.
The beneficial effect of the mechanical lock with function of anti-prizing that the utility model provides is: because the cross section of interlock boss is asymmetric polygon, rotate to carry out illegal release after being difficult to utilize common tool to its clamping.In addition, the longitudinal section of interlock boss is inverted trapezoidal wide at the top and narrow at the bottom, interlock boss is connected with cage knob main body by a neck and the intersection of the adjacent side of interlock boss is provided with chamfering, has further increased and has utilized common tool it to be prized or is stirred the difficulty with illegal release.
