The working principle is as follows: if the combination of the mechanical lock 12 is 666, that is, the number 6 corresponds to the guiding hole 1228, the combination disks 1224 are sequentially shifted from left to right, so that the three numbers 6 on the three combination disks 1224 are all located at the central position, so that the three guiding holes 1228 are in a concentric hole state, the hand-turning wheel 1241 is rotated clockwise for three circles, so that the turning rod 1243 drives the driving bevel gear 1244 to rotate, so that the driven bevel gear 1231 drives the worm 1232 to rotate counterclockwise while being linked, so as to drive the worm wheel 1235 to rotate, the first turning shaft 1234 drives the first driving wheel 1236 to rotate while rotating with the worm wheel 1235, the first driving wheel 6 drives the first driven wheel 2351 to rotate through the driving belt 1233, the second turning shaft 1252 drives the first transmission gear 1253 to rotate while rotating with the first driven wheel 2351, the rotation direction of the first transmission gear 1253 is opposite to the rotation direction of the hand-turning wheel 1241, so that the first transmission gear 1253 rotates counterclockwise to drive the double-sided rack 1256 engaged therewith to move toward the guiding hole 1228, the combination of the guide ribs 1257 and the guide slide 1258 can keep the double-sided rack transmission plate 1256 moving horizontally all the time, meanwhile, the second transmission gear 1254 is driven to rotate clockwise as the movement in the direction opposite to the first transmission gear 1253, so that the second transmission gear 1254 drives the third transmission gear 1263 to rotate counterclockwise, the third rotating shaft 1262 rotates along with the third transmission gear 1263 and drives the second driving wheel 1261 to rotate at the same time, so that the second driven wheel 1266 is driven to rotate by the triangular transmission belt 1264, the second driven wheel 1266 drives the spool 1267 to rotate by the central shaft 1265, so that the spool 1267 rotates counterclockwise to rewind the pull rope 1275, thereby generating a pulling force on the positioning rod 1271, the inner spring 1272 is forced to be drawn and contracted from the original state, so that the positioning rod 1271 is separated from the positioning hole and contracted towards the fixed cylinder 1273, further, the first drawer 1103 and the second drawer 1105 can be pulled freely without being restricted by the jumper 1271.
Compared with the prior art, the invention has the technical progress that: the electronic installation cabinet device is provided with the single-lock double drawers, and the two drawers can be simultaneously locked or unlocked without adopting a motor through the combination of the installation box, the gear code mechanism, the worm gear mechanism, the main power mechanism, the gear rack transmission mechanism, the traction rope rolling and releasing mechanism, the telescopic positioning mechanism and other components, so that the electronic installation cabinet device is convenient, safe and stable in locking and unlocking and low in manufacturing cost.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
