It is simple, reasonable, new style, and could save space and improve efficiency. It could be used in kinds of workbench device. And the invention has very bright prospect.

Description

Attached frame type combined shear-fork streatching-lifting mechanism

The combination that the present invention relates to a kind of scissors mechanism improves.Especially attached frame type combined shear-fork streatching-lifting mechanism.

In the prior art, quite general as being applied in daily production and the life of supporting of telescopic lifting with scissors mechanism, modal is to cut fork application arranged side by side by the single-row fork or two of cutting to multiple row.Resemble the scissors fork elevating scaffold car series of products of the usefulness of ascending a height now, they mostly cut fork row form elevate a turnable ladder arranged side by side with two, but exist the heavy poor stability of structure to raise and more defective such as rock.New disclosed Chinese patent invention " supporting, expanding and lifting mechanism for combined shear fork " 200410099095.3 designed a kind of overlapper of novelty, to cut the fork row to become the changeable combination of angle form, stability and efficient that the shearing fork telescopic lifting is supported will be brought revolutionary change.Yet certain space is always occupied in new supporting, expanding and lifting mechanism for combined shear fork bottom after contraction, and greater room improves applicability again and application surface requires not reach as yet desirable and satisfactory from saving.

The objective of the invention is to provide a kind of renewal combination shearing fork telescopic lifting mechanism, it forms the unique texture pattern with the attached fork row of cutting of attached frame group, and it is extensive to make mechanism hold the properer convenience of carrier aircraft part, makes flexible more flexible stability and high efficiency.

The object of the present invention is achieved like this: attached frame type combined shear-fork streatching-lifting mechanism is invested by several stacked attached frame dresses and cuts in the stacked row of fork, attachment point is set as locating point or sliding point pattern, attached frame outer rim can be added annexes such as slide rail or housing, facilitate attached frame telescopic lifting drive to change the scissors rod angle, the combined scissors fork expanding and lifting mechanism that formation can changeable pattern.The attached frame of attached frame type combined shear-fork streatching-lifting mechanism is an in-line that connects and composes to a plurality of linear portions or the many types of formula plane framework of limit shape arbitrarily, can be fit to the chute that the sliding point displacement is slided with holding in the two sides of attached frame linear portion framework or central authorities' folder are empty; Attachment point is set as locating point or sliding point pattern, cuts the attachment point of fork row and is located at scissors rod end or the two scissors rod point of crossings of cutting fork.Attached frame type combined shear-fork streatching-lifting mechanism can close border condition demand according to real field and change combination form arbitrarily, one attached frame can be adorned the attached extremely a plurality of stacked row of fork of cutting that connect for stacked group, and many attached frames can be adorned successively to invest each lamination of cutting in the stacked row of fork or adorn at interval and invest the part lamination; The outer rim of attached frame can be added the annexes such as housing of slide rail or various types.Attached frame type combined shear-fork streatching-lifting mechanism can enclose inside and outside at the frame of attached frame or dressing all kinds of parts in top are finished the telescopic lifting function, can use various drive forms and drive change scissors rod angle, drive dressing was born and realized to attached frame various forms type shape parts and load telescopic lifting.

Changeable, easy to manufacture widely applicable, the load of pattern novel structure that has attached frame type combined shear-fork streatching-lifting mechanism firmly support powerful, flexible steady lifting reliable, save the space and advantage such as raise the efficiency.It can be widely used in implements such as various companion ladder important actor cars, can serve construction work such as building decoration, lifting promotes the mechanical equipment that transports, the fields such as king-post board frame that lifting moving changes comprehensively.Its ingenious remarkable Application and Development is had boundless prospects.

Below in conjunction with the accompanying drawing signal this patent design-calculated structural principle and typical exemplifying embodiment thereof are described further:

(1) attached frame in the legend, (2) cut fork, (3) slide rail, (4) housing, (5) locating point, (6) sliding point.

Accompanying drawing 1, Fig. 2 illustrate the telescopic lifting groundwork of attached frame type combined shear-fork streatching-lifting mechanism, the two sides of attached frame (1) body are provided with dovetail type chute (it can be other all kinds of chutes in the enforcement) among the figure, locating point (5) is fixed in certain position of attached frame (1), and sliding point during telescopic variation (6) is corresponding slippage in chute.With this principle is basic model, and attached frame type combined shear-fork streatching-lifting mechanism can change as required and various forms of combinations are organized out in assembly.Fig. 3 is the yi word pattern attached frame type combined shear-fork streatching-lifting mechanism diagrammatic sketch that has added two slide rails (3); Fig. 4 cuts the example of adorning attached frame (1) in fork (2) the lamination row at interval when low load requires; Fig. 5 and Fig. 6 cut two kinds of examples that the stacked row of fork (2) change attached multi-form attached frame (1); The slide rail (3) of the flexible direction of standard can be selected various types and quantity for use in the enforcement.With the attached frame of same mechanism yi word pattern (1) numerous attached variations can be arranged also, and by several linear portions be connected to form the attached frame of any limit shape (1) just can have countless versions combination to change to come corresponding various actual demands: Fig. 7 be the V-shape combination for example; Fig. 8 is that a kind of three limit type combinations are given an example; Fig. 9 illustrated embodiment of round housing (4) that has been attached frame (1) outer rim attaching; Figure 10, Figure 11, Figure 12 exemplify three kind of four attached frame of flange (1) and invest the example that varying number is cut fork (2) row with multi-form dress; Figure 13 is that another kind is cut the attached frame type combined shear-fork streatching-lifting mechanism example that fork (2) row are not parallel to attached frame (1) limit.When implementing, attached frame (1) and housing (4) can change as required makes various types and moulding, can also be made as wide cut as the attached frame (1) in Figure 10 and Figure 13 example and block the screen formula, makes mechanism cut fork (2) when telescopic lifting and is shielded by attached frame (1) entirely.

The preceence of attached frame type combined shear-fork streatching-lifting mechanism is that attached frame (1) typing successor cuts the variation of fork (2) bar cramp angle and mechanism's flush type shape is stablized constant, application scenario condition demand many different it all can from the array configuration to parts, dispose moulding and change, can enclose inside and outside at the frame of attached frame (1) or dressing all kinds of parts in top are finished the telescopic lifting function, can conveniently use various drive forms and drive to change and cut fork (2) bar cramp angle and drive various forms type shape parts and the load telescopic lifting that dressing was born and realized to attached frame (1).It will open up the New Times that combined scissors fork is used.
