A handle shares the same shaft with the driving gearwheel , and at the same time is pivoted with a positioning rod with positioning rollers, and the handle drives the driving gearwheel to rotate. The driven gearwheel is provided in co-shaft with a front guiding wheel and a rotary wheel. The driven gearwheel, the front guiding wheel and the rotary wheel are provided with non-synchronous travel control mechanisms. The driven gearwheel is provided with a saliency; the rotary wheel is provided with two grooves that are matched with positioning rollers; the positioning rod is pressed on the rotary wheel by a spring; the rotary wheel is connected with the principal locking tongue by means of a pivoted connecting rod. A stop is controlled to move by a clipping sheet and a guiding sheet, and the clipping sheet and the guiding sheet are pivoted together; the clipping sheet is provided with a rear hook that is matched with the saliency of the driven gearwheel; the guiding sheet is provided with a slot that is matched with a lock head.

Description
Technical field
The utility model belongs to field of lockset, particularly relates to a kind of mechanical anti-theft lock.
Background technology
Theftproof lock is widely used in the daily life, generally can be divided into mechanical anti-theft lock and automatic locking, and the basic structure of mechanical lock all is similar, all is directly to promote dead bolt with tapered end.This theftproof lock in use, each switch lock all will use key, is not very convenient; Torque when turning key simultaneously is bigger, and the wearing and tearing of key and tapered end are more serious.
Summary of the invention
The technical problems to be solved in the utility model is to avoid using too much key, and a kind of mechanical anti-theft lock that can shut with handle is provided.
For this reason, the utility model has adopted following technical scheme: mechanical anti-theft lock, comprise housing, tapered end, handle, main dead bolt, block, tapered end and handle are installed on the housing, block can limit the motion of main dead bolt, it also comprises driving gear, driven gear, and driving gear drives driven gear and rotates, and drives main dead bolt motion indirectly; Handle is coaxial with driving gear, and is pivoted with the backstay of band positioning roller simultaneously, and handle drives the driving gear rotation; Coaxial front jocket wheel, the runner of being provided with of driven gear, driven gear, front jocket wheel, runner are provided with asynchronous range controlling mechanism, driven gear has projection, have two grooves that match with positioning roller on the runner, backstay is pressed on the runner with spring, and runner links to each other with main dead bolt by the connecting rod that articulates; Described block is controlled its motion with screens sheet and prerotation vane, and screens sheet and prerotation vane are articulated, and the screens sheet has the pintle that matches with the projection of driven gear, and prerotation vane has the groove that matches with tapered end.Described asynchronous range controlling mechanism is to be installed with a pin on the driven gear, and front jocket wheel and runner all have the groove of fan annular, and the fan-shaped angle of groove is less than the fan-shaped angle of groove on the runner on the front jocket wheel, and pin passes from two grooves.When driven gear rotated, the pin that sets firmly on it also rotated in two grooves, when forwarding certain angle to, drove front jocket wheel and rotated; Continue rotation, then drive runner and rotate, realize the asynchronous Stroke Control of driven gear, front jocket wheel, runner with this.
The utility model also can adopt following further technical scheme: have two side connecting rods on the described runner, respectively be pivoted one and stretch out the secondary dead bolt of housing; The shift fork of this oblique tongue motion of oblique tongue and control also is housed on the housing, has projection on the driving gear, described shift fork matches with this projection.
The utility model turns handle in use, and driving gear can drive driven gear, drives runner then and rotates, thereby spur main dead bolt motion, reaches the purpose of switch lock, need not use key and tapered end; In the time of need adding insurance, continue to turn handle, then the projection of driven gear spurs the pintle of screens sheet, and the screens sheet drives block and moves to certain position, can limit the rotation of driving gear, and handle can't be unblanked; Be provided with side connecting rod and secondary dead bolt on the runner, move, can play antitheft effect better with main dead bolt; Handle is controlled oblique tongue by shift fork, under the situation that does not need to lock a door, can play windbreak function easily.

The specific embodiment
Referring to accompanying drawing.The theftproof lock of present embodiment comprises housing 1, handle 2, and tapered end 3, handle 2 coaxial driving gear 5 and the backstays 9 of being pivoted with have projection 7 on the driving gear 5, have positioning roller 10 on the backstay 9, and handle 2 can drive driving gear 5 rotations; Driving gear 5 drives driven gear 6 and rotates, and projection 8 is arranged, coaxial front jocket wheel 11 and the runner 12 of being provided with of driven gear on the driven gear 6, have the groove 15 of fan annular on front jocket wheel and the runner, have pin 14 on the driven gear, pass from groove, the angle of groove is less than the angle of groove on the runner on the front jocket wheel; Have two grooves 13 on the runner 12, match with positioning roller 10; Backstay 9 is pressed on the runner 12 by spring; Runner 12 also is articulated with connecting rod 16, links to each other with main dead bolt 4, is articulated with two side connecting rods 23 simultaneously, links to each other with secondary dead bolt 24; The insurance division branch comprises prerotation vane 17 and screens sheet 18, is installed with pin 19 on the housing 1 simultaneously, but fixed guide sheet 17 and screens sheet 18; Prerotation vane 17 has the groove 20 that matches with tapered end 3, and screens sheet 18 has the pintle 21 that matches with the projection 8 of driven gear; Prerotation vane 17 and the screens sheet 18 common blocks 22 that drive move; Also be provided with shift fork 25 and oblique tongue 26 on the housing 1, shift fork 25 matches with the projection 7 of driving gear 5, can be driven by driving gear and rotate and drive oblique tongue 26 motions.
Present embodiment is when shutting, turn handle 2, driving gear 5 rotates, and drives driven gear 6, pin 14 moves in groove 15, after moving certain stroke, promote front jocket wheel 11, with the groove 13 in the positioning roller 10 release runners 12, pin 14 promotes runner 12 rotations simultaneously, by connecting rod 16 main dead bolt 4 is released housing, and by side connecting rod 23 secondary dead bolt 24 is released housing, this moment, the dead bolt of present embodiment all was in the state of stretching out.Continue to turn handle 2, driving gear 5 drives driven gear 6 and is rotated further, pintle 21 motions on the projection 8 pulling screens sheets 18 on the driven gear, make block 22 move to locked position, block driving gear 5, driving gear 5 can't be rotated, then whole theftproof lock is in the state of shutting.
When unblanking, with key turns tapered end 3, the groove 20 pulling prerotation vanes 17 of tapered end by matching with it are withdrawn into relaxation state with block 22, but all freely-movables of each parts this moment.Oppositely turn handle 2, driving gear 5 rotates, and driving driven gear 6, pin 14 moves in groove 15, after moving certain stroke, promote front jocket wheel 11, with the groove 13 in the positioning roller 10 release runners 12, pin 14 promotes runner 12 rotations simultaneously, by connecting rod 16 main dead bolt 4 is drawn in housing, and by side connecting rod 23 secondary dead bolt 24 is drawn in housing, continue to turn handle 2, projection 7 on the driving gear 5 is stirred fork 25, drives oblique tongue 26 withdrawal housings, and this moment, whole theftproof lock was in unlocking condition.
