Description
Technical field
The utility model relates to a kind of transmission mechanism of compact shelving accessory, refers in particular to a kind of hand cranking device of transmission mechanism of compact shelving.
Background technique
Shaking the hand due to its complex structure of existing transmission mechanism of compact shelving, and driving mechanism noise when activity is larger, easily breaks off relations, and uses very inconveniently, is badly in need of technological improvement.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, and the hand cranking device of the transmission mechanism of compact shelving of the little difficult unhook of noise.
For addressing the above problem, the hand cranking device of a kind of transmission mechanism of compact shelving described in the utility model, it is characterized in that: described hand cranking device is by support, chain, output wheel, wheel for inputting and two auxiliary wheels form, described support is quadrilateral, and be arranged with output wheel and wheel for inputting at its two, on support between output wheel and wheel for inputting, be also provided with two auxiliary wheels, described chain is enclosed within on output wheel and wheel for inputting, and two auxiliary wheels divide and are located at chain two inner sides, described wheel for inputting, output wheel and two auxiliary wheels are to be all fixed on support by axle, and the top of wheel for inputting is also provided with and shakes the hand, described shakes the hand by the body of shaking the hand, the handle of shaking the hand forms with the lid of shaking the hand.Above-mentioned project organization is comparatively simple.
As preferably, described for the fixing axle of wheel for inputting and the body of shaking the hand, by three sections of cylinders not of uniform size, formed, the maximum cylinder in bottom is used for fixedly wheel for inputting, the cylinder of top minimum is connected with the body of shaking the hand, and between is also provided with a bearing, shake the hand body bottom is also connected with an interior eccentric wheel, and interior eccentric wheel is connected with intermediate cylindrical, is also equipped with steel ball between the two.Above-mentioned design is by steel ball in axle and the interior eccentric rotation that contacts to realize, and noise can be very little, and very flexible, and structure is also simple.
Compared with prior art, the utility model has the advantage of: structure is with respect to simply, and by steel ball in axle and the interior eccentric rotation that contacts to realize, noise can be very little, also very flexible, the body of shaking the hand rotates also can be very laborsaving, rotating also can be more smooth.
Accompanying drawing explanation
according to drawings and embodiments the present invention is described in further detail below.
Fig. 1 is the structural representation of the hand cranking device of a kind of transmission mechanism of compact shelving described in the utility model.
Fig. 2 is the assembling schematic diagram that the utility model is shaken the hand with axle.
As illustrated in figs. 1 and 2,1, support; 2, chain; 3, output wheel; 4, wheel for inputting; 5, auxiliary wheel; 6, the body of shaking the hand; 7, the handle of shaking the hand; 8, the lid of shaking the hand; 9, axle; 10, bearing; 11, interior eccentric wheel; 12, steel ball.
Embodiment
As shown in Figure 1, the hand cranking device of a kind of transmission mechanism of compact shelving described in the utility model is comprised of support 1, chain 2, output wheel 3, wheel for inputting 4 and two auxiliary wheels 5, support 1 is quadrilateral, and with axle, be fixed with output wheel 3 and wheel for inputting 4 respectively at two, on support 1 between output wheel 3 and wheel for inputting 4, with axle, be also fixed with two auxiliary wheels 5, chain 2 is enclosed within on output wheel 3 and wheel for inputting 4, two auxiliary wheels 5 minutes are located at 2 liang of inner sides of chain, the top of wheel for inputting 4 is also connected with and shakes the hand, and shakes the hand by the body 6 of shaking the hand, the handle 7 and shake the hand and cover 8 and form of shaking the hand.
As shown in Figure 2, being used for fixedly wheel for inputting 4 consists of three sections of cylinders not of uniform size with the axle 9 of the body 6 of shaking the hand, the maximum cylinder in bottom is used for fixedly wheel for inputting 4, the cylinder of top minimum is connected with the body 6 of shaking the hand, and between is also equipped with a bearing 10, body 6 bottoms of shaking the hand are also connected with an interior eccentric wheel 11, and interior eccentric wheel 11 is connected with intermediate cylindrical, is also equipped with steel ball 12 between the two.
Further illustrate, during use, only need rotate the handle of shaking the hand, drive the wheel for inputting of bottom to rotate, by chain, output wheel rotated, auxiliary wheel be make to transmit more stable, by steel ball in axle and the interior eccentric rotation that contacts to realize, noise can be very little, also very flexible, shake the hand between body and axle, be equipped with that bearing rotary moves up also can be very laborsaving, rotating also can be more smooth, and whole structure is also very simple.
The above is preferred forms of the present invention, not protection domain is limited, and designs under the prerequisite of spirit not departing from the present invention, all should fall in the definite protection domain of claims of the present invention.
