The specific embodiment
At Fig. 1, among Fig. 2 and Fig. 3, the utility model is a kind of theftproof lock, it comprises casing, side at casing is a lock panel, a side that is positioned at lock panel in casing is provided with locking bolt and oblique tongue, also be provided with control panel in the casing, control panel is connected with motor, be provided with position detecting switch with the motor adjacent, between the output shaft of motor and locking bolt, be provided with transmission device, on transmission device, be provided with the clutch switching device shifter, transmission device is set to travelling gear, travelling gear is meshed with output shaft and tooth bar respectively between the tooth bar of the output shaft of motor and clutch switching device shifter, described clutch switching device shifter comprises tooth bar and clamp, clamp is provided with the stroke groove, the stroke groove is an inverted T-shaped, in the stroke groove, be installed with trundle, trundle is connected with tooth bar, on clamp, be provided with spring, clamp presses trundle by spring, when manually unblanking by the key tooth, clamp can overcome spring with clamp under the stirring of key tooth separates with trundle, on locking bolt, also be connected with oblique tongue striking gear, tiltedly the tongue striking gear is that one-directional rotation is connected with locking bolt, tiltedly be provided with the transmission push rod between tongue striking gear and the oblique tongue, the oblique tongue plate that is connected on transmission push rod and the oblique tongue connects, the transmission push rod can drive oblique tongue plate and move, on oblique tongue plate, be provided with bayonet lock and oblique tongue grab, bayonet lock can move along with oblique tongue plate, tiltedly the tongue grab by oblique tongue pillar and oblique tongue plate for being rotationally connected, bayonet lock can be when unblanking moves with oblique tongue plate to be crossed prominent hook and stretches into coupler body inside, connect and be drive state, be provided with uvula between described locking bolt and the oblique tongue, uvula is connected with grab by connecting rod, on connecting rod, be provided with back-moving spring, back-moving spring is at uvula and tiltedly between the tongue striking gear, locking bolt is connected with universe rod by the universe rod trundle, and the universe rod trundle can move along with locking bolt moves the promotion universe rod.
Using method of the present utility model is: first kind of switching lock mode, the electric opening and closing lock mode that promptly adopts generally speaking, after control panel receives blocking order, can detect the position of oblique tongue and uvula, tiltedly tongue should be in extended position, uvula should be in retracted position, and tiltedly the tongue grab is in vertical position under action of reset spring.Motor rotation this moment, through gear train, tooth bar, the tooth bar trundle, and the clamp that tightly suppresses the tooth bar trundle under spring action drives the locking bolt lateral movement of turning left, and makes the universe rod interlock strut by the universe rod trundle simultaneously, thereby reach the purpose of locking, after control panel receives unlock instruction, can detect the position of oblique tongue and uvula, tiltedly tongue should be in extended position, uvula should be in retracted position, motor reverse rotation this moment, through gear train, tooth bar, the tooth bar trundle, and the clamp that tightly suppresses the tooth bar trundle under spring action drives the locking bolt motion of turning right, and makes universe rod interlock contraction by the universe rod trundle simultaneously, thereby reaches the purpose of unblanking.In locking bolt moved to right process, the oblique tongue shifting block that is installed on the locking bolt can be stirred oblique tongue push rod, promoted oblique tongue plate again and moved to right, and when oblique tongue bayonet lock is crossed the tip location of oblique tongue grab, tiltedly tongue will be locked in retracted position.And this moment, oblique tongue push rod was got back to initial upright position under action of reset spring.Uvula 9 stretches out in spring action bottom, and push door leaf open gently on the limit.When uvula stretches out fully, can drive oblique tongue grab 5 and clockwise rotate around oblique tongue pillar, discharge oblique tongue bayonet lock, tiltedly tongue will stretch out.
Second kind of switching lock mode, promptly the key that in emergency circumstances adopts manually opens and closes the lock mode: when using the key manual block, the lock core shifting block counterclockwise rotates, at first overcoming action of reset spring power up passes clamp, separate with the tooth bar trundle until clamp, the key moving tooth on the shooting the lock-bolt of taking advantage of a situation then moves to left thereby promote locking bolt, make the universe rod interlock strut by the universe rod trundle simultaneously, thereby reach the purpose of locking; When using key manually to unblank, the rotation of lock core shifting block clockwise direction, at first overcoming action of reset spring power up passes clamp, separate with the tooth bar trundle until clamp, take advantage of a situation then key moving tooth on the shooting the lock-bolt, move to right thereby promote locking bolt, make the universe rod interlock strut by the universe rod trundle simultaneously, thereby reach the purpose of locking.In locking bolt moved to right process, the oblique tongue shifting block that is installed on the locking bolt can be stirred oblique tongue push rod, promoted oblique tongue plate again and moved to right, and when oblique tongue bayonet lock is crossed the tip location of oblique tongue grab, tiltedly tongue will be locked in retracted position.And this moment, oblique tongue push rod was got back to initial upright position under action of reset spring.Uvula stretches out in spring action bottom, and push door leaf open gently on the limit.When uvula stretches out fully, can drive oblique tongue grab and clockwise rotate around oblique tongue pillar, discharge oblique tongue bayonet lock, tiltedly tongue will stretch out.
Also can rotate oblique tongue shifting block indoor, thereby oblique gyrus lingulais is contracted by the handle that is installed on the door leaf.
