Be described in further detail below in conjunction with the oblique tongue assembly of accompanying drawing theftproof lock of the present utility model:
Fig. 1 is bowing to schematic diagram of theftproof lock, for the ease of watching, has removed the loam cake of theftproof lock;
Fig. 2 is the side schematic view of the annexation between thumb wheel and the connecting axle in the oblique tongue assembly, for the ease of watching, has removed part;
Fig. 3 is bowing to enlarged diagram of following plectrum.
The specific embodiment:
As depicted in figs. 1 and 2, the oblique tongue assembly of a kind of theftproof lock of the present utility model comprises: oblique tongue 1, oblique tongue back-moving spring 3, connecting axle 2, location-plate 4, baffle plate 6, commutation back-moving spring 7, catch 8, thumb wheel 12, last plectrum 5, following plectrum 11 and thumb wheel back-moving spring 13, tiltedly tongue 1 is fixed on the front end of connecting axle 2, the postmedian of connecting axle 2 passes location-plate 4 and baffle plate 6 successively, location-plate 4 is fixed on the theftproof lock, baffle plate 6 is fixed on the connecting axle 2 and on theftproof lock and slides, catch 8 is equipped with at the rear portion of connecting axle 2, commutation back-moving spring 7 is housed between baffle plate 6 and catch 8, plectrum 5 and following plectrum 11 are housed between location-plate 4 and baffle plate 6, thumb wheel 12 is contained on the theftproof lock, last plectrum 5 and following plectrum 11 are contained in the above and below of thumb wheel 12 respectively, between last plectrum 5 and following plectrum 11, thumb wheel back-moving spring 13 is housed, on the thumb wheel 12 between last plectrum 5 and the thumb wheel back-moving spring 13, pad 22 is housed also, tiltedly on the connecting axle 2 between tongue 1 and the location-plate 4 oblique tongue back-moving spring 3 is being housed.Two projections 9 are arranged on the connecting axle 2 of catch 8 rear ends, and this projection 9 axially is symmetrically distributed with respect to connecting axle 2, and this projection 9 is after catch 8 is installed, and makes on connecting axle 2, with fixing catch 8.There is a screwdriver slot 10 connecting axle 2 rear ends, and a side of theftproof lock has a locking shell hole 17.When tiltedly tongue 1 needs commutation,, rotate 180 ° and get final product as long as screwdriver is inserted into the screwdriver slot 10 from locking shell hole 17.
As shown in Figure 3, there is a left block 21 in the left side of following plectrum 11, there is a right block 20 on the right side, the two ends of thumb wheel back-moving spring 13 are stuck on left block 21 and the right block 20, and in the right projection 19 in the upper end of right block 20, there is a mating holes 18 centre of following plectrum 11, this mating holes 18 is square hole or hexagonal hole, be sleeved on it on the thumb wheel 12, make down plectrum 11 and thumb wheel 12 when rotating, be not easy to throw off, promptly descend plectrum 11 forever along with thumb wheel 12 rotates.Cylinder fixing on projection 19 and the theftproof lock cooperates, to limit the angle that thumb wheel 12 rotates.Following plectrum 11 is a punching structure, thumb wheel 12 is smart casting stainless steel, both closely connect, when mounted, to descend plectrum 11, thumb wheel 12 and thumb wheel back-moving spring 13 to install earlier, then above-mentioned three parts are packed between location-plate 4 and the baffle plate 6, will go up plectrum 5 again and pad 22 is packed into, can easily the thumb wheel assembly be installed on the theftproof lock like this.
Operating principle:
When last plectrum 5 under the promotion that driver blade makes progress, drive thumb wheel 12 and following plectrum 11 and clockwise rotate together, go up plectrum 5 promotion baffle plates 6 simultaneously, it is slided backward along theftproof lock, connecting axle 2 and oblique tongue 1 and then baffle plate 6 slide backward together, oblique tongue 1 retraction theftproof lock, and security door is opened; After resetting under the driver blade effect of spring thereon, following plectrum 11 rotates counterclockwise under the effect of thumb wheel back-moving spring 13 and resets, thumb wheel 12 and last plectrum 5 also rotate counterclockwise under its drive and reset, baffle plate 6 is under the effect of oblique tongue back-moving spring 3 and commutation back-moving spring 7, move forward along theftproof lock, tiltedly tongue 1 stretches out outside the theftproof lock again.
Because the difference of the opening direction of security door, generally be divided into and open inwards and outwards open, therefore when needs change the direction of oblique tongue, then can in the locking shell hole 17 corresponding, insert screwdriver with the connecting axle 2 of oblique tongue 1, push hard oblique tongue 1 by the time Rotate 180 degree when tiltedly tongue 1 goes out lock body fully, oblique tongue 1 can be resetted by oblique tongue back-moving spring 3 and commutation back-moving spring 7 then, so just reached oblique tongue 1 commutate purpose.
Do not breaking away under the prerequisite of the present utility model; various modification and improvement that engineers and technicians in this area make the technical solution of the utility model all should fall into protection domain of the present utility model, and the technology contents that the utility model is asked for protection will be as the criterion all to be documented in right.
