Description

A new type of lock body

【Technical field】

The utility model relates to a lock.

【Background technique】

The opening of the existing lock is usually that the lock body can be opened by rotating the lock head in one direction, so that the lock body is easy to be opened by being damaged in various ways, and the safety performance is relatively small. And when the lock body has a bolt tongue and a three-prong tongue or a square tongue, it is generally opened by turning the lock head with a key to open the bolt bolt and the three-prong tongue or square tongue. inconvenient. Later, some lock bodies also appeared on the market. When the oblique bolt retracts, the three-prong tongue or square tongue will automatically pop out, but these lock bodies are when the oblique bolt retracts slightly into the lock housing, the three-prong tongue or square tongue will pop out. pop up. Because the three-pronged tongue or square tongue is not aligned with the keyhole on the door at this time, when the door is closed, the three-pronged tongue or square tongue will scratch the panel on the door, so that the three-pronged tongue or square tongue and the panel will be scratched. The service life of the lock body is reduced, and the closing strength of the lock body is increased, which brings inconvenience to life.

Three-prong tongue 2 is provided with three-prong tongue guide groove 201 and can slide in three-prong tongue guide groove 201 and drives three-prong tongue 2 telescopic toggle block 29, is provided with between toggle block 29 and three-prong tongue 2 and can toggle block 29 reset toggle block reset torsion spring 202, lock housing 1 is hinged with trident tongue lock plate 24 that pushes trident tongue 2 tightly when trident tongue 2 retracts and can be driven by toggle block 29 to rotate and avoid trident tongue 2, A locking piece resetting torsion spring 203 for resetting the three-prong tongue locking piece 24 is provided between the three-prong tongue locking piece 24 and the lock housing 1 . Because the three-prong tongue lock piece 24 withstands the three-prong tongue 2, so the three-prong tongue 2 can not be pressed into the lock body by external force, the second must be by stirring the toggle block 29 to make the three-prong tongue lock piece 24 rotate to avoid the three-prong tongue 2, so that The three-prong tongue locking piece 24 cannot push against the three-prong tongue 2, so that the three-prong tongue 2 can continue to retract.

The pushing piece 44 is provided with a pushing piece chute 404 , and the trident tongue 2 is provided with a pushing piece guide post 205 inserted into the pushing piece chute 404 to guide the pushing piece 44 . When the trident tongue 2 is retracted into the lock housing 1 , it drives the push piece 44 to rotate, so that the lock head plectrum 61 can be pushed to the push piece 44 .

The action of the lock body is as follows:

The handle is unlocked, the handle is put into the rudder 4, the handle is turned to drive the rudder 4 to rotate, the rudder 4 drives the rudder paddle 45 to rotate, the rudder paddle 45 rotates to drive the oblique tongue puller 41 to rotate, The rudder paddle 45 drives the transmission paddle 42 to rotate, and the transmission paddle 42 drives the second paddle 22 of the trident tongue to rotate, and the rotation of the second paddle 22 of the trident tongue drives the toggle block 29 to move in the telescopic direction of the trident tongue 3, and the toggle block 29 drives the three-prong tongue lock piece 24 to rotate, so that the three-prong tongue lock piece 24 is far away from the three-prong tongue 2. When the three-prong tongue 2 is retracted, it will no longer touch the three-prong tongue lock piece 24. Move inside the shell 1, when the three-prong tongue 2 is retracted into the lock shell 1, the first block 71 is stuck on the first clamping step 27, and the three-prong tongue 2 cannot rebound and stretch out under the elastic force of the torsion spring; turn the rudder The rotation of the dial 45 drives the oblique tongue puller 41 to rotate at the same time, so that the oblique tongue puller 41 moves the oblique tongue 3 to retract, and drives the transmission dial 42 to rotate, and the rotation of the transmission dial 42 will rotate the unlocking bottom block 81, Make the unlocking slider 82 avoid the oblique tongue 3, and will not be driven to slide by the oblique tongue 3, the unlocking piece 84 will not be driven to rotate, the first clamping device 7 will not be unlocked, and the retraction of the oblique tongue 3 will make the linkage The sheet 95 no longer leans against the latch tongue 3, so that the second block 91 will rotate under the elastic recovery of the second block reset torsion spring 96, and be stuck on the second engaging step 28. The second block 91 Will drive linkage plate 95 to rotate. Trident tongue 2 and oblique tongue 3 are all opened like this. In this way, when the handle opens the latch tongue 3, the three-pronged tongue 2 will not automatically pop up, only when the latch tongue 3 is squeezed and retracted, the latch tongue 3 will drive the unlocking slider 82 to move, and the movement of the unlocking slider 82 will drive the unlocking piece 84 rotates, and the rotation of the unlocking piece 84 will drive the first block 71 to rotate away from the three-prong tongue 2, so that the first block 71 will no longer block the three-prong tongue 2, and the first clamping device 7 will be unlocked; When it stretches out under the elastic restoring force, it will drive the linkage piece 95 to rotate, and the rotation of the linkage piece 95 will drive the second block 91 to rotate away from the trident tongue 2, the second clamping device 9 is unlocked, and the trident tongue 2 will be in the elastic position of the torsion spring. Eject under restoring force.

To unlock the lock head, turn the lock paddle 61 counterclockwise to drive the first paddle 21 of the three-prong tongue to rotate, and the rotation of the first paddle 21 of the three-prong tongue drives the toggle block 29 to move in the direction in which the three-prong tongue 3 stretches, and the toggle block 29 drives The three-prong tongue lock piece 24 rotates so that the three-prong tongue lock piece 24 is far away from the three-prong tongue 2, and the three-prong tongue 2 is opened. At the same time, the first block 71 clamps the three-prong tongue 2, and the push piece 44 also rotates to the The position where the lock paddle 61 can be pushed; then turn the lock paddle 61 clockwise, the lock paddle 61 drives the reset block 68 to move, and at the same time pushes the push piece 44 to move, and the movement of the push piece 44 will push the oblique tongue pull piece 41 rotates, and the follow-up action is consistent with the process in which the oblique tongue pulling piece 41 opens the oblique tongue 3 in the handle unlocking. After the oblique tongue 3 is opened, the reset block 68 resets under the action of the torsion spring, which drives the locking end plectrum 61 to rotate, so that the locking end plectrum 61 can not push against the three-pronged tongue 2. The process that trident tongue 2 ejects automatically is consistent with the process in the handle unlocking.
