Description
Technical field
The utility model relates to the mechanical transmissioning technology field, particularly a kind of linkage mechanism.
Background technique
Linkage mechanism is the motion of using always, and itself and drive unit (for example reducing motor, hydraulic electric motor etc.) are used, and have wide range of applications, and may be used in all kinds of machinery such as power door operation, transmission device.In the daily life, may move the occasion that impacts to drive unit at some, need be with drive unit and control unit isolation or sealing; Also have some products that decorative appearance is had relatively high expectations, also need drive unit and each connecting rod are isolated with casing.But existing linkage mechanism, its range of movement is bigger, with isolation of casing linkage or sealing the time, need offer bigger space or emptiness avoiding hole on casing, causes comparatively difficulty of isolation or sealing, and isolation or sealing effect are relatively poor.With reference to shown in Figure 1, during owing to linkage mechanism A motion, drive connecting rod 71 does not have fixing point of intersection with follower link 72, need very wide swing, when utilizing casing B linkage A isolation or sealing, need offer macropore C on casing B, isolation or sealing be difficulty relatively.
The model utility content
Main purpose of the present utility model provides a kind of linkage mechanism, is intended to reduce the hunting range of connecting rod, makes casing can isolate or seal linkage mechanism better, improves and isolates or sealing effect.
The utility model linkage mechanism comprises fixing rod, driving lever, follower lever and take-off lever, described fixing rod and drive unit are fixed, the head end of described driving lever and the head end of fixing rod articulate, and the tail end of driving lever and the head end of described take-off lever articulate, the driving lever middle part is provided with first arc section, and the center of circle is the center that driving lever is connected with fixing rod; The head end of described follower lever and fixing rod tail end articulate, and the tail end of follower lever and the tail end of described take-off lever articulate, the follower lever middle part is provided with second arc section, and the center of circle is the center that follower lever is connected with fixing rod, and the projection of described first arc section and second arc section is intersected.
Preferably, said fixing bar, driving lever, follower lever and take-off lever articulate by rotating shaft.
Preferably, also comprise at least a with in the lower levelling plate: metal sliding shim, oil-containing pad or plastic cement pad are positioned at and respectively articulate the position.
Driving lever in the utility model linkage mechanism and follower lever are provided with cross one another first arc section and second arc end, and two arc section projections are intersected.During connecting rod mechanism movement; driving lever is along rotating with the pivot joint center of fixing rod; follower lever is along rotating with the pivot joint center of fixing rod; its movement locus is all by the projection intersection point; during with the box sealing linkage mechanism; can be better to fixing rod and driving mechanism sealing or isolation, the protection power mechanism is isolated the noise that power mechanism produces.

Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 2, the utility model linkage mechanism A comprises fixing rod 10, driving lever 20, follower lever 30 and take-off lever 40, fixing rod 10 is fixed with drive unit, the head end of the head end of driving lever 20 and fixing rod 10 articulates, and the head end of the tail end of driving lever 20 and described take-off lever 40 articulates, driving lever 20 middle parts are provided with first arc section 21, and the center of circle is the center that driving lever 20 and fixing rod 10 articulate; The head end of follower lever 30 and fixing rod 10 tail ends articulate, and the pivot joint of the tail end of the tail end of follower lever 30 and take-off lever 40, and follower lever 30 middle parts are provided with second arc section 31, and the center of circle is the center that follower lever 30 and fixing rod 10 articulate; The projection of first arc section 21 and second arc section 31 is intersected, and intersection point is K.In one embodiment, the plane parallel at the plane at driving lever 20 places and follower lever 30 places, the projection of first arc section 21 and second arc section 31 intersects at the K point.
With reference to Fig. 3, first arc section 21 in the driving lever 20 intersects at the K point with second arc section 31 in the follower lever 30, when drive unit drive connecting rod mechanism when the direction of arrow is rotated, first arc section 21 is all the time by the K point, and second arc section 31 is also all the time by the K point.When utilizing casing A that drive unit is isolated or sealing, only need on the corresponding position of casing, to offer an emptiness avoiding hole C who is a bit larger tham intersection and get final product.Even after the assembling, also this emptiness avoiding hole can be used the seal ring shutoff, with the raising sealability, thereby protect drive unit, linkage mechanism A and electric elements better.In addition, but the noise that sent of isolation drive device, linkage mechanism A also.Another benefit of the utility model linkage mechanism A is: in the occasion that outward appearance is had relatively high expectations, movement parts can be hidden into a box house better, thereby improve the total quality of product.
With reference to Fig. 5, aforementioned link mechanism also can be provided with rotating shaft 55, be positioned at the pivot joint position of said fixing bar 10, driving lever 20, follower lever 30 and take-off lever 40, the pivot joint position of driving lever 20 and take-off lever 40 for example, the pivot joint position of fixing rod 10 and driving lever 20, the pivot joint position of fixing rod 10 and follower lever 30, the pivot joint position of follower lever 30 and take-off lever 40 etc., each connecting rod is around this rotating shaft 55 rotations.
Aforementioned link mechanism also can be provided with pad, this pad can be at least a with in the lower levelling plate: metal sliding shim, oil-containing pad or plastic cement pad, be positioned at and respectively articulate the position, the pivot joint position of driving lever 20 and take-off lever 40 for example, the pivot joint position of fixing rod 10 and follower lever 30 etc.Above-mentioned pad has self-lubricating property, with the friction process of other parts in, can separate out lubricator, for example graphite, lubricant oil or plastic cement particle etc.
Take-off lever 40 be driven object and fixedly connected, it can produce the curvilinear motion track under the drive of driving lever 20 and follower lever 30, drive to be driven object up-down.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
