Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in the figure, a comprehensive limit plate includes a lock case (44), a lock cover (01), a comprehensive limit plate (34), a lock bolt assembly, an inner lock dial shaft (02), and a lock pin ( 03) and the locking plate (06), the feature is: the lock bolt assembly is provided with a guide post (222), and the lock case (44) is provided with a first guide post (461), a second guide post post (462), third guide post (463) and fourth guide post (464), the locking plate (06) is provided with a first guide hole (061), a second guide hole (062), the The first guide hole (061) and the second guide hole (062) are sleeved on the first guide post (461) and the second guide post (462) respectively and are slidably fitted with them. The plate (34) is erected above the locking plate (06) and the locking bolt assembly and linked with the locking bolt assembly, and the comprehensive limiting plate (34) is provided with pins (351), The first guide groove (341), the second guide groove (342), the upper and lower guide grooves (343), the first limit notch (344), the second limit notch (345), the limit protrusion ( 346), the guide groove (343) is further divided into: drive limit groove (3431), lock lock groove (3432) and groove (3433) according to the division of regional functions, the first comprehensive limit plate A guide groove (341) is sleeved on the second guide post (462) and is slidably matched with it, and the second guide groove (342) of the integrated limiting plate is sleeved on the third guide post (463) and slidingly fit with it, the guide groove (343) is sleeved on the guide post (222) and rolls fit with it, and the locking plate (06) is also provided with a groove ( 063) and drive groove (064), the groove (063) cooperates with the pin (351) to form a clutch mechanism, and the lock pin (03) includes two parts: pin end (031), The connection end (032), the pin end (031) is inserted into the corresponding socket of the lock case (44) and the lock cover (01), and the limit protrusion (346) is in the Below the lock bolt (03), the inner lock dial shaft (02) is set in the lock case (44) and rotates with it, and its head can form a lock with the first limiting notch (344) For the anti-locking function after the bolt is locked, its head can form the function of preventing the locking bolt from being triggered and locked with the second limiting notch (345).

The working process of the present utility model is as follows: in the state shown in Figure 1, the lock bolt assembly stretches out of the lock housing, and the guide post 222 inserted on the lock bolt assembly is in the guide groove 343 of the comprehensive limit plate 34 close to the groove 3433 At one end, the comprehensive limit plate 34 is subjected to gravity at this time, and the limit projection 346 on it falls on the lock bolt 03, that is, the integrated limit plate 34 is supported by the lock bolt 03, and the lock bolt is not restricted in the horizontal direction , can be unlocked normally; at this time, if the inner lock dial shaft 02 is turned counterclockwise to lock, the head of the inner lock dial shaft 02 will cut into the first limit gap 344 of the integrated limit plate 34, and push the integrated limit plate Moving up makes the groove 3433 abut against the guide post 222, the integrated limiting plate 34 is restricted from moving in the vertical direction, and the lock bolt assembly is restricted from moving in the horizontal direction, that is, the unlocking function is prevented.

When the lock bolt assembly is driven back into the lock housing by external force, the guide post 222 inserted on the lock bolt assembly moves to the right, and finally is located near the drive limit groove 3431 of the guide groove 343 of the comprehensive limit plate 34 At one end, at the same time, the driving groove 064 of the locking plate 06 is thrust, and the locking plate 06 moves to the right, until the groove 063 on it blocks the pin 351 on the comprehensive limiting plate 34, at this time, the comprehensive limiting The plate 34 is restricted in the vertical direction, and the driving limit groove 3431 restricts the guide post 222 on the lock bolt assembly, that is, the movement of the lock bolt assembly in the horizontal direction is restricted, and the final position is shown in FIG. 2 . At this time, if the inner lock dial shaft 02 is turned counterclockwise to lock, the head of the inner lock dial shaft 02 will cut into the second limit gap 345 of the integrated limit plate 34, and push the integrated limit plate to move to make the groove 3433 resists the guide post 222, the integrated limiting plate 34 is restricted from moving in the vertical direction, and the lock bolt assembly is restricted from moving in the horizontal direction, that is, the self-triggering locking function of the lock bolt is prevented.

In the locked state of the lock bolt shown in Figure 1, if the outdoor handle assembly is violently opened, since the connecting end 032 of the lock pin 03 is connected to the outside handle assembly, prying the outside handle assembly will drive the lock pin 03 The pin end 031 of the lock shell is separated from the pin hole 441 of the lock housing 44, and the lock pin 03 no longer plays a blocking role on the limit projection 346 of the integrated limit plate 34, and all the integrated limit plates 34 fall under the action of gravity, and the lock lock The draw-in groove 3432 is stuck on the guide post 222, causing the lockbolt assembly to be unable to move to the right, and the anti-theft lock can no longer be unlocked, that is, the anti-picking lock locking function has been realized.

The above is only a specific embodiment of the utility model, and does not make any formal restrictions on the utility model. For those skilled in the art, without departing from the technical solution of the utility model, the Several simple modifications, replacements and modifications all fall within the protection scope of the present utility model.
