Specific embodiment
Below in conjunction with accompanying drawing, this utility model is described further:
The present embodiment includes casing 1 and chamber door 2, and chamber door 2 is hinged on casing 1, and chamber door 2 is provided with anti-theft locking dress
Put.
Anti-theft locking mechanism includes special spanner, intermediate transmission frame, lock core 12 and ring gear 9.Special spanner and middle biography
Moving frame is the core place that this utility model realizes anti-theft feature, after locking chamber door 2 takes off special spanner and intermediate transmission frame
Take away.
Be provided with cylindrical grooves 7 on described chamber door 2, Anti-theft locking mechanism is arranged in cylindrical grooves 7 so that
Survey tool is difficult to put to good use, thus preventing of preventing that stealer from passing through to survey and draw replicates special spanner and intermediate transmission frame.
Described ring gear 9 is arranged on the bottom land of cylindrical grooves 7 by jump ring 8, and the bottom land of cylindrical grooves 7 is machined with
Cambered way, the back side of ring gear 9 is provided with lock 10, and lock 10 passes through cambered way and is fixedly connected on ring gear 9, arc
Being disposed to of shape slideway provides activity space to lock 10, when lock 10 follows ring gear 9 rotation, slides in described arc
Slide in road.
The central authorities of the bottom land of cylindrical grooves 7 are machined with circular hole, and one end of described lock core 12 passes through ring gear 9 and above-mentioned
Circular hole after be arranged on the bottom land of cylindrical grooves 7 by jump ring 8, the other end of lock core 12 is provided with as spanner bare terminal end
Six prisms 16, the middle part of lock core 12 is machined with external toothing 13, and described special spanner includes handle 3, rotary shaft 5 and positioning disk 6,
Handle 3 is fixedly mounted on one end of rotary shaft 5, in the other end of rotary shaft 5 is provided with and is matched with six above-mentioned prisms 16
