Between it is very limited, and thrust or pulling force size to telescoping mechanism has certain requirement, also requires the motion in telescopic process
Track meets the requirements, although the above structure can realize stretching motion, generally existing transformation efficiency is low, this cause as
Fruit will realize the equipment that the pulling force or thrust of a certain particular value must select higher force performance, and the raising of mechanical property is most
Along with the increase of equipment volume, it is impossible to the need for meeting specific small space, a kind of small volume is needed in device fabrication, is turned
Change the accurate telescoping mechanism of efficiency high, movement locus.
Utility model content
The purpose of this utility model is to overcome technical problem present in above-mentioned motion telescoping mechanism, there is provided a kind of rigidity
Chain stretches skeleton structure.
To achieve these goals, the utility model provides following technical scheme：
A kind of rigid chain is stretched skeleton structure, including base plate and the guide chute plate that is arranged on base plate, and the guiding is slided
Frid both sides set up cant board, and bearing is provided between the cant board top, and drive gear, institute are connected with the bearing
State drive gear to be engaged with rigid chain rivet, driven holding wheel is provided between the drive gear and rigid chain rivet, it is described driven
Keep wheel to be arranged on driven holding wheel shaft, multiple rigid chain mainboards, the rigid chain mainboard are additionally provided with the cant board
Between be connected by rigid chain rivet, the rigid chain mainboard upper outer is provided with rigid chain connecting plate, the adjacent rigidity
Chain mainboard is connected by rigid chain connecting plate.
Preferably, the rigid chain mainboard is set between cant board and guide chute plate.
Preferably, the rigid chain mainboard is provided with two connecting holes, the rigid chain mainboard side is trapezoidal shape, its
Angle is 0 ° -90 °.
Preferably, the rigid chain mainboard forms rigid chain by rigid chain connecting plate.
The beneficial effects of the utility model are：The flexible skeleton structure of this rigid chain is nibbled by drive gear and rigid chain rivet
Stretch out and the indentation of conjunction promotion rigid chain, reduce the degree of difficulty and cost of processing, by setting the trapezoidal of rigid chain mainboard
Angle ensures the degree of crook of rigid chain, and so as to ensure that the precise degrees of stretching structure movement locus, rigid chain mainboard sets
Rounding is equipped with, its service life is extended.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only used to explain this
Utility model, is not used to limit the utility model.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of rigid chain stretches skeleton structure, including base plate 7 and is arranged on leading on base plate 7
To coulisse 8, the both sides of guide chute plate 8 set up cant board 3, and the cant board 3 is provided with bearing 1, institute between top
State and drive gear 2 is connected with bearing 1, the drive gear 2 is engaged with rigid chain rivet 10, the drive gear 2 and rigid chain
Driven holding wheel 5 is provided between axle 10, the driven holding wheel 5 is arranged on driven holding wheel shaft 4, in the cant board 3
Multiple rigid chain mainboards 9 are additionally provided with, are connected by rigid chain rivet 10 between the rigid chain mainboard 9, the rigid chain mainboard 9
Upper outer is provided with rigid chain connecting plate 6, and the adjacent rigid chain mainboard 9 is connected by rigid chain connecting plate 6.
The rigid chain mainboard 9 is arranged between cant board 3 and guide chute plate 8, and the rigid chain mainboard 9 is provided with two
Individual connecting hole 91, as described in Figure 2, one of connecting hole is used for installing rigid chain rivet 10, and another is used for connecting rigid chain
Connecting plate 6, the side of rigid chain mainboard 9 is trapezoidal shape, and its angle is 0 ° -90 °, and the rigid chain mainboard 9 passes through rigid chain
Connecting plate 6 forms rigid chain 11.
