Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
Fig. 1 to Fig. 4 illustrates a kind of parking rope linkage coupling, including connecting rod 1, lower wedge shape tensioning block 2, upper wedge shape tensioning block 3, tensioning block back-moving spring 4, spring base 5, tensioning spring 6, draw ring 7 and link 8.Ratchet 11 in lower wedge shape tensioning block 2, upper wedge shape tensioning block 3, tensioning block back-moving spring 4 and connecting rod 1 forms wedge shape self-regulation device.
Connecting rod 1 one end is provided with connecting plate, connecting plate has two installing holes for being connected with parking backstay 10, and connecting rod 1 other end is provided with boss.Tensioning spring 6 is arranged in connecting rod 1 and is compressed between boss and spring base 5 to make the trend of the oriented side's motion of connecting rod 1, namely one end of tensioning spring 6 contacts with boss, the other end of tensioning spring 6 contacts with spring base 5, and spring base 5 is arranged in connecting rod 1 and is fixed on link 8.Lower wedge shape tensioning block 2 opposite side that be fastened on connecting rod 1 and be positioned at spring base 5 relative to upper wedge shape tensioning block 3, the inner chamber of lower wedge shape tensioning block 2 and upper wedge shape tensioning block 3 can hold connecting rod 1 bar footpath, and the intracavity sidewall processing of lower wedge shape tensioning block 2 and upper wedge shape tensioning block 3 to have ratchet structure, the profile of lower wedge shape tensioning block 2 and upper wedge shape tensioning block 3 be that wedge shape is to coordinate with link 8 inner chamber wedge-like portion.The bar path portion processing of connecting rod 1 up and down wedge shape tensioning block 2 and upper wedge shape tensioning block 3 correspondence has ratchet 11 with the ratchet structure cooperating with lower wedge shape tensioning block 2 and upper wedge shape tensioning block 3 intracavity sidewall, makes connecting rod 1 be held axially fixed clamping connecting rod 1.Being additionally provided with tensioning block back-moving spring 4 and draw ring 7 between upper and lower wedge shape tensioning block and spring base 5, draw ring 7 is stuck between upper and lower wedge shape tensioning block and spring base 5 and is positioned at tensioning block back-moving spring 4 periphery.Link 8 is the box-like structure of about one both ends open, and upper and lower wedge shape tensioning block, tensioning block back-moving spring 4 and spring base 5 are contained in box-like structure.What the two sides, front and back of link 8 was respectively symmetrically is provided with square hole structure, and the two ends of spring base 5 are fixed on link 8 by square hole structure.The top of link 8 has a square opening, and draw ring 7 is inserted between upper and lower wedge shape tensioning block and spring base 5 by this opening or extracts.Link 8 left end processing have cammed surface with upper and lower wedge shape tensioning block cooperating.Link 8 has upper and lower two parts to be fastened and connected to form to facilitate installation.Draw ring 7 is a rectangular block architecture, and the lower end of rectangular block architecture has U-shaped groove, and the top of rectangular block architecture is provided with Handheld Division.Handheld Division includes the elongated hole structure of groove structure or the rectangular block architecture upper vertical side being arranged on two sides, rectangular block architecture top, and the upper end processing of rectangular block architecture has chamfering structure.
Draw ring 7 is the switch of this device work.After pulling up, lower wedge shape tensioning block 2 and upper wedge shape tensioning block 3 axially allow displacement.Now, connecting rod 1 has the trend moved right under the effect of tensioning spring 6, drives lower wedge shape tensioning block 2 and the axially-movable of upper wedge shape tensioning block 3.In upper and lower wedge shape tensioning block motor process to the right, move along inclined-plane separated from one another, the size that in upper and lower wedge shape tensioning block, ratchet structure is sized larger than in connecting rod 1 outer ratchet 11.Now tensioning spring 6 discharges, and connecting rod 1 ejects and reaches the compression stress of design and drag-line 10 is carried out pretension.
When the moment that draw ring 7 is left behind, upper and lower wedge shape tensioning block moves right separated from one another.Upper and lower wedge shape tensioning block separates with the inside and outside ratchet of connecting rod 1, and connecting rod 1 moves right.Now under the active force of tensioning block return spring 4, upper and lower wedge tensioning block return, clamp again the ratchet 11 of connecting rod 1.Before parking drag-line power, tensioning block return spring power sum are more than tensioning spring power, upper and lower wedge shape tensioning block can circulate under the effect of tensioning spring 6 and be engaged with connecting rod 1 ratchet, unclamp, and does not stop circulation until both sides match.Hereafter, parking drag-line power, tensioning block return spring power sum are more than tensioning spring power, and upper and lower wedge shape tensioning block block is engaged with connecting rod 1 ratchet 11, will no longer produce relative displacement between the two, and knot constitutes rigidity.Extra, for ensureing reliability, it is possible to select again to snap in mechanism draw ring, higher reliability will be realized.
Above in conjunction with accompanying drawing, the present invention is carried out exemplary description; the realization of the obvious present invention is not subject to the restrictions described above; as long as have employed the various improvement that the design of the method for the present invention carries out with technical scheme; or the not improved design by the present invention and technical scheme directly apply to other occasion, all in protection scope of the present invention.
