The limiting column limits the rotation angle of the sector gear, so that an unlocking person can know whether the lock bolt is completely extended or retracted.

Furthermore, a display mechanism is further arranged in the lock body and comprises a swing rod, a torsional spring, a first fixing rod, a display window, a second fixing rod, a third fixing rod, a driving rod and an indication board, the display window is arranged on the side wall of the lock body, the driving rod is arranged on the sector gear, the first fixing rod, the second fixing rod and the third fixing rod are arranged on the inner wall of the lock body, the swing rod is rotatably arranged on the first fixing rod, the indication board is connected with the swing rod, the torsional spring is sleeved on the first fixing rod, and two ends of the torsional spring are respectively in lap joint with the second fixing rod and the swing rod; the sign is written with the word "open", "close".

The spring action of torsional spring to the pendulum rod for when the spring bolt withdraws, the sign shows as "opening" on showing the window. The staff can confirm responsible person fast according to the responsible unit that the lock core corresponds. The third fixing rod is used for limiting the swing angle of the swing rod.

Compared with the prior art, the utility model has the advantages that: the method has the characteristics of convenience in operation, low manufacturing cost and visual display, is used in the closed area managed by multiple units together, effectively solves the problem of responsibility tracing, and is very suitable for the closed area managed by multiple units together.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1 to 4. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.

The utility model provides a technical scheme: a multi-core single-bolt mechanical lock comprises a lock body, wherein 4 lock cylinders 14 are symmetrically arranged in the lock body from top to bottom, and the 4 lock cylinders 14 are unlocked by different keys. Each lock cylinder 14 is connected with a set of driving mechanisms; a plurality of lock cylinders 14 can drive the lock bolts 2 through a driving mechanism to realize unlocking and unlocking.

The driving mechanism comprises a sector gear 4 and a limiting column 12, wherein the sector gear 4 is connected with the lock cylinder 14, and the sector gear 4 is driven to synchronously rotate when the lock cylinder 14 is inserted with a key and rotates. The sector gear 4 is provided with an arc through groove 401 concentric with the body thereof, the limiting column 12 is fixedly arranged on the inner wall of the lock body 5, and part of the limiting column 12 is inserted into the arc through groove 401; the upper side and the lower side of the lock tongue 2 are both provided with racks 3, and the sector gear 4 is meshed with the racks 3.

Still be provided with display mechanism in the lock body 5, display mechanism includes pendulum rod 10, torsional spring 15, first dead lever 8, display window 7, second dead lever 9, third dead lever 11, actuating lever 13, sign 6, display window 7 sets up on the 5 lateral walls of lock body, actuating lever 13 sets up on the sector gear 4, first dead lever 8, second dead lever 9 and third dead lever 11 set up 5 inner walls of lock body. The third fixing rod 11 limits the swing angle of the swing rod 10. The swing rod 10 is rotatably arranged on the first fixing rod 8, the indicating plate 6 is connected with the swing rod 10, the torsion spring 15 is sleeved on the first fixing rod 8, and two ends of the torsion spring are respectively lapped with the second fixing rod 9 and the swing rod 10; the indication board 6 is written with the characters of 'on' and 'off'.

The utility model discloses a theory of operation does: when 4 lock cylinders 14 are all rotated to the closed state, the bolt 2 is inserted into the door frame. The sector gear 4 is disengaged from the rack 3 on the bolt 2, at this time, any lock cylinder 14 is rotated to unlock, and the sector gears 4 on the other lock cylinders 14 do not obstruct the movement of the bolt 2. When one of the lock cylinders 14 opens the lock, the driving rod 13 loses the limitation on the swing rod 10, and the swing rod 10 swings under the action of the elastic force of the torsion spring 15 until the indicator 6 is displayed as 'on' in the display window 7. When the staff forgets to lock the door by mistake, the responsible person can be determined according to the corresponding display window 7.
