Description

A kind of driven member

Technical field

This utility model relates to mechanical field, particularly to a kind of driven member used with cam engagement。

Background technology

Cam mechanism is promoted driven member to make the mechanism that regulation moves back and forth or swings by gyration or the reciprocating motion of cam。Existing driven member is only the structural member of L-type, and structure is relatively simple, causes driven track in every day use process simple, cannot realize spacing in driving process；And the insufficient strength of this driven member, very easily rupture in transmission process, cause service life relatively low。

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is in that to provide the variation of a kind of transmission track, can realize spacing and that service life is longer driven member。

The technical solution of the utility model is achieved in that a kind of driven member, including L-shaped body, it is characterized in that: include articulated section, the both sides of this articulated section are respectively arranged with drive division and latch part, the middle part of this articulated section is provided with hinge hole, this drive division includes drive rod and is arranged at the limiting section of drive rod tip inside, this limiting section includes the groove caved in, the bottom surface of this groove is provided with two stopper slots, two stopper slots are respectively arranged at the two ends of groove floor, the two ends of this groove vertical direction and the junction of drive rod are respectively arranged with the first curved portions and the second curved portions, the radius of this first curved portions is more than the radius of the second curved portions, the width of drive rod is gradually reduced to drive rod direction by articulated section。

By adopting technique scheme, driven member is effectively played spacing effect by this limiting section in transmission process, and by the cooperation of two stopper slots, the transmission track making driven member is more diversified, and the width of drive division is gradually reduced, the connection reliability of drive division and articulated section it is effectively guaranteed while ensure that self-strength, not easy fracture in transmission process, extend the service life of driven member on the whole。

This utility model is further arranged to: this latch part includes curved base portion and is arranged at the snap close section of base portion end, and the medial surface of this snap close section is provided with lock buckling groove, and the lateral surface of snap close section is provided with breach, and the length of this breach is more than the length of lock buckling groove。

By adopting technique scheme, latch part improves the stability that driven member is connected when using with counterpart, on the top of lock buckling groove, breach is set, the end being effectively guaranteed base portion is narrower, ensure that this latch part can be moved in less space and realize snap close, topology layout is reasonable, it is simple to realize。

This utility model is further arranged to: the width of described base portion is successively decreased to both sides by middle part。

By adopting technique scheme, under ensure that the premise that materials are relatively economized, reasonably use the internal stress of base portion, reached the effect of proof strength, it is simple to realized。

This utility model is further arranged to: the end of described base portion bends downwards, and the end of this base portion is arc shape, and the part that the end of this base portion bends downwards is higher than the degree of depth of lock buckling groove。

By adopting technique scheme, the end of base portion is arc shape, it is simple to this end and driven member realize snap close, and the part that bends downwards of the end of base portion is higher than the degree of depth of lock buckling groove, ensure that and realize the stability of snap close with driven member, topology layout is reasonable, it is simple to realize。

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings。
