Beneficial effect: master slider and being synchronized with the movement by gear transmission between slide block in the utility model, but to carrying out locked from slide block, can be prevented it from moving axially, thus reaching pick-proof effect by limit for length's elastic rod and resigning hole and groove structure.And master slider is sealed hiding.The utility model reasonable in design, controls master slider and moves synchronously to drive and move from slide block, simultaneously can to carrying out locked from slide block, effective, is very beneficial to promotion and implementation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the another kind of using state schematic diagram of Fig. 1.
In figure, label 1 is door-plate, and 2 is lock housing, and 3 is doorframe, and 4 is main chute, 5 is master slider, and 6 is from chute, and 7 is from slide block, and 8 is lock core and driven wheel, and 9 is limit for length's elastic rod, 10 is shallow slot to make way, and 11 is dark slot to make way, and 12 is holddown groove, and 13 is loose slot, and 14 is sliding sleeve, 15 is fixed cover, and 16 is spring, and 17 is gear platform, and 18 is block edge, 19 is rosette for lock, and 20 is main tooth bar, and 21 is from tooth bar, and 22 for driving tooth bar, 23 is master gear, and 24 is from gear, and 25 is guide peg, and 26 is thrust spring.
detailed description of the invention
Embodiment 1: a kind of electricity meter box anti-picking device, see Fig. 1, is vertically provided with main chute 4 and from chute 6 respectively in the arranged on left and right sides of lock housing 2, and is respectively installed with master slider 5 and from slide block 7.Main chute 4 and be greater than master slider 5 respectively and from slide block 7 length from the length of chute 6, thus master slider 5 can be made and have mobile surplus respectively from slide block 7.From the upper end of slide block 7 and be provided with compression spring 26 between chute 6 inwall, lock housing upper end is provided with pilot hole, is connected with guide peg 25 from slide block 7 upper end, and this guide peg 25 inserts in pilot hole, and compression spring 26 is sleeved on outside guide peg 25.The rosette for lock 19 arranged from slide block 7 lower end and doorframe 3 locks.
Master slider 5 and be respectively arranged with main tooth bar 20 from slide block 7 medial surface upper end and from tooth bar 21.Master slider 5 and from being respectively arranged with the master gear 23 that is arranged on lock case sidewalls between slide block 7 upper end and from gear 24.Main tooth bar 20 engages with master gear 23, and master gear 23 engages with from gear 24, engages from gear 24 with from tooth bar 21.
The dorsal part of master slider 5 is provided with and drives tooth bar 22, and is provided with the lock core and driven wheel 8, driven wheel and lock pin coaxial that are arranged on lock case sidewalls.Driven wheel engages with driving tooth bar 22.
Be provided with fixed cover 15 at master slider 5 with from the lock case sidewalls between slide block 7, in fixed cover 15, be set with sliding sleeve 14, in sliding sleeve 14, be set with limit for length's elastic rod 9.This limit for length's elastic rod 9 comprises left section and right section, and being connected with between two sections is the spring 16 that both stretch.
Left section of described limit for length's elastic rod 9 and right section is respectively arranged with gear platform 17, and the two ends mouth of pipe of sliding sleeve 14 is respectively arranged with block edge 18, and two terminal block platforms are positioned at inside the block edge of two ends.The effect of limit for length's elastic rod 9 is, has certain telescopic resilience, but minimum length and maximum length are defined.
The lower end inside limit of master slider 5 is disposed with shallow slot to make way 10 and dark slot to make way 11, is disposed with holddown groove 12 and the leg-of-mutton loose slot 13 of rectangle from the lower end inside of slide block 7.See Fig. 2, when master slider 5 with synchronously move down from slide block 7 after, the two ends of limit for length's elastic rod 9 fall into dark slot to make way and leg-of-mutton loose slot 13 respectively, limit for length's elastic rod 9 can not infinitely can only be compressed by relatively compressing, and now can keep having from slide block moving surplus (fit clearance transmittance process can meet this and move surplus) by a small margin.See Fig. 1, after master slider 5 and continuing from slide block 7 synchronously moves down, the two ends of limit for length's elastic rod 9 fall into the holddown groove 12 of shallow slot to make way 10 and rectangle respectively, and limit for length's elastic rod 9 can not be compressed again, thus locked by movable slider.
Embodiment 2: another kind of electricity meter box anti-picking device, accompanying drawing is not drawn, and content is substantially the same manner as Example 1, something in common does not repeat, unlike: by described master gear or be set to combined wheels from gear, namely comprise gear and pinch roller, both elastic compressions frictional fit.
