As shown in fig. 1, an embodiment of the present invention provides a linkage mechanism, which includes a base 1, a driving plate 2, a first connecting rod 3, and a second connecting rod 4; the driving plate 2 is movably arranged on the base 1 and used for receiving unlocking acting force; the middle part of the first connecting rod 3 is hinged with the driving plate 2, and one end of the first connecting rod 3 is hinged with the middle part of the second connecting rod 4; at least one of one end of the first connecting rod 3 and two ends of the second connecting rod 4 is hinged with a stopper 5, and the stopper 5 is movably arranged on the base 1.
The embodiment of the utility model provides an among link gear and the tool to lock, link gear's fender piece can set up with the spring bolt separation of lock to the realization is when the drive plate receives the effort of unblanking, because the middle part of first connecting rod articulates in the drive plate, consequently, at the in-process that the drive plate removed, the articulated round pin axle of first connecting rod and drive plate also removes to the equidirectional direction, then, borrows the link gear that this first connecting rod and second connecting rod constitute again, can drive and keep off the piece and remove to the position of unblanking, simple structure, the cost is lower.
The linkage mechanism can be applied to a lockset, when a lock is arranged in the lockset, one end of the first connecting rod 3 and only one end of the two ends of the second connecting rod 4 are hinged with the blocking piece 5, specifically, when the lock is unlocked, the driving plate 2 receives unlocking acting force and moves towards the unlocking direction, and the middle part of the first connecting rod 3 is hinged to the driving plate 2, so that the first connecting rod 3 and the hinged pin shaft of the driving plate 2 also move towards the same direction in the moving process of the driving plate 2, and then the blocking piece 5 can be driven to move to the unlocking position of the lock by virtue of the connecting rod mechanism consisting of the first connecting rod 3 and the second connecting rod 4, so as to realize unlocking. At this time, the other two free ends of the first link 3 and the second link 4 may be provided with the stoppers 5, or may not be provided with the stoppers 5, and one of the two free ends needs to be fixed.
When there are two locks in this tool to lock, the one end of first connecting rod 3, and the both ends in the both ends of second connecting rod 4 are articulated respectively have and keep off piece 5, specifically, when these two locks are in the state of unblanking respectively, drive plate 2 accepts the power of unblanking and moves to the direction of unblanking, because the middle part of first connecting rod 3 articulates in drive plate 2, consequently, in the in-process that drive plate 2 moved, first connecting rod 3 also moves to the equidirectional removal with the articulated round pin axle of drive plate 2, then, can drive two by means of the link mechanism that this first connecting rod 3 and second connecting rod 4 constitute and keep off piece 5 and move to the position of unblanking of two locks respectively to realize unblanking. At this time, the stopper 5 may be provided at the other free end of the first link 3 and the second link 4, or the stopper 5 may not be provided, and the other free end may or may not be fixed. If the other free end adopts a non-fixed mode, two-opening-one can be realized.
In this embodiment, one end of the first connecting rod 3 and two ends of the second connecting rod 4 may be respectively hinged with the blocking piece 5, so that the linkage mechanism may be applied to a three-lock two-open lock, and when any one of the three blocking pieces 5 is fixed, namely, the lock corresponding to the blocking piece 5 is in a locked state, and the blocking piece 5 abuts against a lock tongue of the lock, the driving board 2 can drive the first connecting rod 3 and the second connecting rod 4 to drive the other two blocking pieces 5 to move under the action of an unlocking acting force until the two blocking pieces are respectively moved to unlocking positions of the two locks in the unlocked state, so as to achieve unlocking (specifically, refer to the unlocking process of the three-lock two-open lock set below).
One set of structure can be used for one lock, two locks and three locks, so that the practicability is high and the flexibility is high; the condition that a lock is damaged can be realized by adopting a two-opening one-opening or three-opening two-way mode, normal unlocking can be realized under the condition that the lock or lock tongue equipment of the lock is not damaged, and the cost is saved.
in some examples, the first link 3 has a first inflection point α, the first link 3 is hinged to the driving plate 2 by the first inflection point α, the second link 4 has a second inflection point β, the second link 4 is hinged to one end of the first link 3 by the second inflection point β, and the first inflection point may be near the middle of the second link 4 and be far from the end of the first link 3 so as to facilitate the counterclockwise movement of the same, in which case, since the first link 3 and the second link 4 may respectively grip three blocks under the condition of their own shapes, it is not necessary to separately design and extend part of the blocks, but to set the specifications of the blocks to be the same, and at this time, when any one or more blocks are damaged or worn and need to be replaced, only the same batch of standard parts may be applied, rather than separately designing the standard parts for the first block, the second block, and the third block.
In some examples, the moving directions of the driving plate 2 and the three stoppers 5 on the base 1 may be the same; one end of the first connecting rod 3 and two ends of the second connecting rod 4 are respectively provided with a first limiting hole 31; the three stoppers 5 are respectively hinged in the corresponding first limiting holes 31 through first pin shafts 51; the first limiting hole 31 is used for providing a movable space for the position change of the first pin shaft 51, the first connecting rod 3 is hinged to the driving plate 2 through the second pin shaft 32, and the first connecting rod 3 is hinged to the second connecting rod 4 through the third pin shaft 33. Due to the structural design, the linkage mechanism is conveniently applied to the lockset, and linkage unlocking from the driving end to the lock end is realized. In practice, the three first limiting holes 31 may be replaced by circular holes or long holes with larger diameters, respectively, except that when a circular hole with a larger diameter is used, the limiting effect is unstable, which easily causes deviation in limiting the free end of the connecting rod, and in some cases, a limiting error may also occur, for example, in order to provide a sufficient movement space in the length direction, the width direction of the circular hole with a larger diameter is required to be the same as the length in the length direction, but at this time, because the length in the width direction is larger than the necessary width, not only is the pin head diameter of the hinge pin shaft at the free end of the link mechanism required larger, but also when the link mechanism is in transmission, the driving plate 2 is required to provide larger driving displacement due to insufficient thrust at the edge of the limiting hole diameter. If the limiting hole is designed to be a long hole, when the hinge pin shaft at the free end of the connecting rod mechanism moves to the end point of the long hole, the contact area between the hinge pin shaft at the free end of the connecting rod mechanism and the edge of the long hole is small, and although the problem that the driving plate 2 needs to provide larger driving displacement cannot be caused, the transition of the hinge pin shaft at the end point of the long hole is not stable enough, and the use comfort of an operator is easily reduced. Therefore, in this embodiment, the three first limiting holes 31 are preferably oblong holes.
Based on the above embodiment, the linkage mechanism has three linkage situations. For the sake of description, with reference to fig. 1, the three flights 5 are designated in sequence as a first flight 5a, a second flight 5b and a third flight 5 c.
