Abstract
The slip-off preventing zip structure that the present invention provides, including the zip head being arranged in tooth bar and the circlip blocking described zip head, described circlip is installed in the groove in described tooth bar, this slip-off preventing zip structure also includes the zip cap blocking described zip head, described zip cap is arranged in described tooth bar, coordinates with described tooth bar inside thread.The present invention can reduce back-up ring stress, even if external diameter can change after circlip resilience, does not also have the risk come off.
Description
Technical field
The present invention relates to a kind of slip-off preventing zip structure.
Background technology
The Zipper-type gearshift being frequently used at present, is connected to the tooth bar of drive mechanism by zip, drive its move into
Row gearshift.Present zip structure, as it is shown in figure 1, be matched in clearance between zip and tooth bar, is provided with circlip in tooth bar, its
It is arranged in the groove in tooth bar.Circlip can prevent zip from coming off in motor process.But due to tooth bar structure, add
Work technique and the existence of circlip manufacturing tolerance, when after circlip resilience, external diameter can change.And if groove dimensions
When all reaching upper dimension bound with tooth bar aperture size, its matching relationship will change.When after back-up ring resilience, external diameter is less than one
During definite value, when this hour rack carries out axially-movable, pulling force acts on circlip, and circlip can deviate from tooth bar groove, back-up ring
The risk that comes off i.e. is there is with zip.
Summary of the invention
The technical problem to be solved in the present invention is to provide and a kind of relatively reliable slip-off preventing that zip cannot come off is effectively ensured
Zip structure.
To achieve these goals, the technical scheme that the present invention takes is:
Described slip-off preventing zip structure, including the zip head being arranged in tooth bar and the bullet blocking described zip head
Property back-up ring, described circlip is installed in the groove in described tooth bar, this slip-off preventing zip structure also include blocking described in draw
The zip cap of lock head, described zip cap is arranged in described tooth bar, coordinates with described tooth bar inside thread.
Being provided with screw thread outside described zip cap, inside has the through hole passed for zip, with described zip head contact one
End is provided with the recess closed with described zip head matching form.
Described zip cap is provided with at least two and installs groove near circlip one end.
Using technique scheme, zip cap is threaded into tooth bar, when rack drives zip carries out axially-movable, draws
Power acts on one end of zip cap, and axial force is decomposed reduction back-up ring stress by screw thread, even if external diameter can be sent out after circlip resilience
Changing, does not haves the risk come off yet.Recess and zip head form fit, improve the stability of zip structure.Install
Zip cap is rotated during the convenient installation of groove, convenient for assembly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of zip cap in structure shown in Fig. 1；
Fig. 3 is the structural representation of zip structure in prior art.
Being labeled as in figure:
1-circlip, 2-zip cap, 3-recess, 4-tooth bar, 5-install groove.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the invention is made further details of theory
Bright, to help those skilled in the art that present inventive concept, technical scheme are had more complete, accurate and deep understanding.
As shown in Figure 1 to Figure 2, the invention provides a kind of slip-off preventing zip structure, including the zip being arranged in tooth bar 4
Head and the circlip 1 blocking this zip head.Described circlip 1 is installed in the groove in described tooth bar 4.
This slip-off preventing zip structure also includes the zip cap 2 blocking described zip head.Zip cap 2 is arranged on described tooth bar
In 4, coordinate with described tooth bar 4 inside thread.Being provided with screw thread outside zip cap 2, inside has the through hole passed for zip, with institute
State zip head contact one end and be provided with the recess 3 closed with zip head matching form.Zip cap 2 sets near circlip 1 one end
There is at least two that groove 5 is installed.
During assembling, first zip head is loaded in tooth bar 4, then zip cap 2 is enclosed within zip is screwed in tooth bar 4, make recessed
Mouth 3 and zip head contact, finally snap in the groove in tooth bar 4 by circlip 1.When zip carries out axially-movable, zip one
The pulling force of end acts on the recess 3 of zip cap 2.Zip cap 2 is fixed with tooth bar 4 by screw thread, can effectively prevent because of bullet
After property back-up ring 1 resilience, external diameter changes, and stops the risk that circlip 1 stress causes zip to come off.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way
Restriction, as long as have employed the inventive method design and the improvement of various unsubstantialities that technical scheme is carried out or the most improved
Present inventive concept and technical scheme are directly applied to other occasion, all within scope.
