Abstract
The utility model discloses a kind of reversible two-way transmission mechanisms, it includes structural support, structural support inner hub location is equipped with central drive gear, a driving rack is respectively provided on two madial wall of structural support, central drive gear is intermeshed with driving rack, more axis I are distributed in structural support inner homogeneous, and the both ends of axis I are arranged with limit scroll wheel, and central drive gear top is provided with rotation control wheel by axis II.Using the above structure, coordinated by the transmission between central drive gear and the driving rack of its both sides, the driving rack can be driven to roll slipping along limit, and then control the telescopic moving of driving rack.
Description
Technical field
The utility model is related to a kind of instrument power transmission fields, and in particular to a kind of reversible two-way transmission mechanism.
Background technology
There are many mechanical apparatus to need actuating unit or mobile device now, but these are all heavy mostly, are not easy
The large-scale drive mechanism or mechanism of operation, it is therefore desirable to design a kind of reversible two-way transmission mechanism.
Utility model content
Technical problem to be solved in the utility model is in view of the above shortcomings of the prior art, and to provide a kind of reversible
Two-way transmission mechanism.
In order to solve the above-mentioned technical problem, the utility model proposes following technical schemes：A kind of reversible Bidirectional driving machine
Structure, it is characterised in that：It includes structural support, and structural support inner hub location is equipped with central drive gear, structure branch
A driving rack is respectively provided on two madial walls of support body, central drive gear is intermeshed with driving rack, structural support
More axis I are distributed in inner homogeneous, and the both ends of axis I are arranged with limit scroll wheel, are set by axis II above central drive gear
It is equipped with rotation control wheel.
The driving rack upper and lower surface is connect by being equipped with limiting slot with limit scroll wheel.
The structural support is the rectangle groove body of a side opening, and lower surface is arranged with 4 fixing sucking disks and connects with ground
It connects.
The utility model has the advantages that：
Using the above structure, coordinated by the transmission between central drive gear and the driving rack of its both sides, it being capable of band
It moves the driving rack and rolls slipping along limit, and then control the telescopic moving of driving rack.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
In figure：Structural support 1, central drive gear 2, driving rack 3, axis I 4, limit scroll wheel 5, axis II 6, rotation
Control wheel 7.
Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of reversible two-way transmission mechanism, it is characterised in that：It includes structural support 1, structure branch
1 inner hub location of support body is equipped with central drive gear 2, and 1 inside two side of structural support is respectively provided with a driving rack 3,
Central drive gear 2 is intermeshed with driving rack 3, and more axis I 4, the both ends of axis I 4 are distributed in 1 inner homogeneous of structural support
It is arranged with limit scroll wheel 5,2 top of central drive gear is provided with rotation control wheel 7 by axis II 6.By using above-mentioned
Deflecting two-way transmission mechanism, in the course of work, by manually rotating rotation control wheel 7, by rotating control wheel 7 with moving axis
II 6, central drive gear 2 is driven by axis II 6, is intermeshed by central drive gear 2 and the driving rack 3 of its both sides,
It drives driving rack 3 to stretch by rack pinion, finally realizes its Bidirectional driving.
Further, 3 upper and lower surface of the driving rack is connect by being equipped with limiting slot with limit scroll wheel 5.Pass through institute
Cooperation between the limiting slot stated and limit scroll wheel 5, can ensure that driving rack 3 normally extends and retracts.
Further, the structural support 1 is the rectangle groove body of a side opening, removes upper surface portion, lower surface
Outside is arranged with 4 fixing sucking disks and is connect with ground.Structural support 1 can be fixed by fixing sucking disk.
The course of work and operation principle of the utility model：
In the course of work, axis is passed through by rotating control wheel 7 with moving axis II 6 by manually rotary motion control wheel 7
II 6 drive driving rack 3, are slided along limit scroll wheel 5 by driving rack 3, and then effectively control stretching for driving rack 3
Go out, achievees the purpose that Bidirectional driving.
Through the above description, those skilled in the art completely can be without departing from this item utility model technological thought
In the range of, it carries out various changes and amendments and is within the protection scope of the utility model.The utility model is not use up
Matters belong to the common knowledge of those skilled in the art.
