The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
9 structural representation as can be seen from accompanying drawing 1 to accompanying drawing, the invention provides the lock that has device for limiting, it comprises housing, the locking bar 10 that is positioned at the curved of housing and can moves along this arc place circumference, the lock core that is positioned at housing and locking bar 10 can be locked, being provided with in the housing that an end is fixed on the housing that the other end is connected with an end of locking bar 10 and locking bar 10 applied has to the back-moving spring 20 of the power of unlocked position movement tendency locking bar 10, offer the arc stopper slot 31 identical with locking bar 20 centers of circle on the housing, offer on the stopper slot 31 and limit groove 311, this restriction groove 311 is opened in the end on a long limit of stopper slot 31, have the connecting rod 13 that passes stopper slot 31 on the locking bar 10, be connected with the device for limiting that is positioned at outside the housing on the locking bar 10.
Device for limiting comprises body 14, button 15 and catch 16.
Have the connecting rod 13 that passes stopper slot 31 on the locking bar 10, body 14 is provided with the jack 144 that matches with connecting rod 13, and body 14 namely plugs with connecting rod 13 by this jack 144.
When device for limiting during at finite-state, pin 161 is positioned at and limits groove 311, this hour locking lever, when device for limiting during in release conditions, button 15 rotates, projection 151 promotes catch 16 and moves, pin 161 with limit groove 311 and be separated.
When back-moving spring 20 pulling locking bars 10 move from latched position to unlocked position, because the restoring force of back-moving spring 20 is bigger, the pin 161 on the locking bar 10 can cause very big impact to the end of stopper slot 31, in the course of time, can produce wearing and tearing, these wearing and tearing can influence the use of lock.In the present embodiment, the end of 161 pairs of stopper slots 31 of pin all can impact with the restriction groove 311 that is positioned at this end and make it wearing and tearing, and these wearing and tearing can influence the movement of pin 161, thereby causes the stuck or inefficacy of device for limiting.
Be set with block 41 on the housing, one end of locking bar 10 has depressed part 11, this depressed part 11 have one from its bottom surface upwardly extending retaining wall 111, when locking bar 10 during at unlocked position, block 41 offsets with retaining wall 111, pin 161 an end of stopper slot 31 and and this end between have the space.
In the present embodiment, housing comprises upper shell 30 and the lower house 40 that is installed together mutually, and stopper slot 31 is arranged on the upper shell 30, and block 41 is arranged on the lower house 40.
Has the locked groove 12 with the clamping separatably of lock core phase on the locking bar 10.
By being increased in block 41 and the retaining wall 111 that offsets when locking bar 10 is positioned at unlocked position, 161 pairs of stopper slots of pin 31 and the impact that limits groove 311 on the locking bar 10 have been avoided, effectively reduce the damage of stopper slot 31 and restriction groove 311, prolonged the application life of lock.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
