Detailed description of the invention
Referring to accompanying drawing, provide the specific embodiment of the present invention, be used for being further described structure of the present invention.
Embodiment 1
The variable combination insurance lock body of the present embodiment is with reference to figure 1-11, its structure comprises: housing 1, sleeve 2, lock core body, sleeve lock jack panel 4 and pivoted arm 5, housing wherein has being fixed in fixing body and having the housing postive stop baffle 1-3 of key hole, and is axially connected to the lock core installing sleeve 1-2 of described housing postive stop baffle 1-3 side; Sleeve 2 is embedded at the inside of described lock core installing sleeve 1-2 and is anchored on described housing 1 inside by the sleeve lock jack panel 4 of side, and it has the inner chamber for accommodating lock core body; Lock core body inserts core retainer plate 3 by blade 7 and forms, and described core retainer plate 3 is provided with the slot for plugging described blade 7, and described blade 7 is made up of one group of single independently laminated structure; Sleeve lock jack panel 4 is tightened in the lock core installing sleeve 1-2 of described housing 1, and is locked in described enclosure interior by the sleeve 2 of its side; Pivoted arm 5 is fixed on the end of described core retainer plate 3, and produces with described core retainer plate 3 and link.Described single independently blade 7 is equipped with the keyhole 7-4 at middle part, the rolling pin that offers successively on blade excircle direction unblanks groove 7-1, rolling pin idle running face 7-2 and blade confined planes 7-3; Axial housing locating slot 1-1 is provided with in the lock core installing sleeve 1-2 of described housing 1, the periphery of described sleeve 2 is provided with the positioning boss 2-3 matched with described housing locating slot 1-1, described positioning boss 2-3 embeds described housing locating slot 1-1, thus described sleeve 2 is connected with described housing 1; The periphery of described core retainer plate 3 is provided with deep gouge 3-1 under axial rolling pin, the inner circumferential of described sleeve 2 is axially arranged with the rolling pin locating slot 2-1 matched with deep gouge 3-1 under described rolling pin, rolling pin 6 is installed under described rolling pin locating slot 2-1 and described rolling pin between deep gouge 3-1, with the inside making described core retainer plate 3 be embedded at described sleeve 2; The end of the nearly housing postive stop baffle 1-3 of described jacket casing 2 is provided with the anti-drilling sheet mounting table 2-2 for installing anti-drilling sheet 8; The end that described core retainer plate 3 is connected with described pivoted arm 5 is provided with screw, and described pivoted arm 5 is fixed on the end of described core retainer plate 3 by plain washer 10, elastic washer 11 and screw 12; The lock core installing sleeve 1-2 periphery of described housing 1 is provided with external screw thread, and whole lock body is by being rotatably connected in the big nut 9 of described lock core installing sleeve 1-2 periphery being fixed on fixing body.
Installation process of the present invention is as follows:
First, blade 7 is inserted on core retainer plate 3, then core retainer plate 3 to be loaded in sleeve 2 and by rolling pin 6, core retainer plate 3 to be connected with sleeve 2, first anti-drilling sheet 8 is loaded in the lock core installing sleeve 1-2 of housing 1, afterwards the sleeve 2 of built-in core retainer plate 3 is loaded in lock core installing sleeve 1-2, screwing in sleeve lock jack panel 4 is undertaken fastening by sleeve 2, after sleeve 2 and sleeve pin jack panel 4 are stretched out in the end of core retainer plate 3, by pivoted arm 5 by plain washer 10, elastic washer 11 and screw 12 tighten the end to core retainer plate 3, finally lock body is installed on cabinet or other fixing bodies, finally by the big nut 9 being rotatably connected in housing 1 periphery, location is installed.
Operating principle of the present invention is as follows:
1, during inserting error key, key inserts blade (7) along keyhole (7-4), when after different leaves composition vane group, rolling pin (6) and rolling pin face (7-2) of dallying contacts, rotate key, blade (7) is idle running in the lamina idle-run groove (3-2) of core retainer plate (3), and its scope of activities is controlled by blade confined planes (7-3);
When 2, inserting correct key, key inserts blade (7) along keyhole (7-4), and blade rolling pin is unblanked groove alignment, and rolling pin (6) falls into rolling pin and to unblank groove (7-1); Rotate key, blade (7) drives core retainer plate (3) to rotate by rolling pin (6), realizes unlocking function.
3, lock core becomes tartar function: pull down pivoted arm (5), plain washer (10), elastic washer (11) and screw (12), sleeve lock jack panel (4) is unloaded with special tool, take off core retainer plate (3), rolling pin (6), blade (7) is readjusted, then installs in order.
The present invention has following features:
1, lock core, partition adopt integrated design, reduce between blade and accumulate tolerance, improve assembly precision;
2, tapered end overall structure adopts summary design, and assembling is simple, is very easy to realize individual and repeatedly splits, assembles, do not destroy tapered end component;
3, blade adopts differential seat angle design, supports the use with variable combination encryption key pair, by changing leaf position, realizes lock core variable combination, safe and reliable, energy-saving material-saving.
