Abstract
The invention discloses a structure for preventing a circlip for a shaft from loosening and reducing the abrasion of the circlip for the shaft. The structure comprises the assembly shaft, the circlip for the shaft, an elastic pin and an assembly housing, wherein the circlip for the shaft, which is mounted in a groove of the assembly shaft, can limit hole direction movement of the assembly shaft, but allows the assembly shaft to rotate; the elastic pin is mounted on the assembly housing; an opening is formed on the circlip for the shaft; and two ears used for controlling the size of the opening are respectively formed on the two sides of the opening; and the elastic pin can be placed in any position on the circumference of the assembly housing, can be in contact with the ears at the opening of the circlip for the shaft, but cannot be contact with the side of the outermost ring of the circlip for the shaft. In the structure, as the circlip for the shaft is not in close fit with the assembly shaft, the degree of friction and abrasion between the circlip for the shaft and the assembly shaft can be greatly reduced, and the circlip for the shaft is prevented from loosening and falling off the groove of the assembly shaft, thereby prolonging the service life of a tool to a great degree.
Description
Technical field
The present invention relates to a kind of structure that prevents that circlip for shaft is loosening and reduce its wearing and tearing, belong to the tools structure field that ratchet wrench etc. need to use circlip for shaft.
Background technique
In prior art, circlip for shaft is a kind of being installed on fluted shaft, is used for fixing component hole to the standard piece of motion, and the internal diameter of this class back-up ring is slightly less than the assembling diameter of axle.Palpus Circlip tongs during installation, inserts jaw in the pincers hole of back-up ring, and expansion back-up ring, just can put on pre-processed axial trough.
In actual using process, owing between circlip for shaft and assembled shaft, relative movement can inevitably occurring, produce wearing and tearing, both relative movement simultaneously easily make circlip for shaft that loosening distortion occurs, and even come off, so the instrument that affects uses.
In use, for preventing circlip for shaft and assembled shaft groove wear excessively and the phenomenon of circlip for shaft generation loose or dislocation.Now adopt a kind of new structure to make improvements, the use of this structure can effectively reduce circlip for shaft and assembled shaft groove wear degree, and prevents that the phenomenon of loose or dislocation from appearring in circlip for shaft.
Summary of the invention
It is a kind of structure that prevents that circlip for shaft is loosening and reduce its wearing and tearing that the object of the invention is to provide, to solve in prior art circlip for shaft and assembled shaft groove wear excessively and the problem of circlip for shaft generation loose or dislocation.
The present invention is achieved by the following technical solutions:
Prevent that circlip for shaft from becoming flexible and reducing the structure of its wearing and tearing, comprise assembled shaft, circlip for shaft, resilient key, assembling shell, described circlip for shaft is arranged in the groove of assembled shaft, the hole of restriction assembled shaft is to motion, but allow assembled shaft to rotate, described resilient key is arranged on assembling shell, described circlip for shaft is provided with an opening, these opening both sides are respectively equipped with an ear of controlling openings of sizes, the position of described resilient key on assembling shell circumferencial direction can be placed arbitrarily, described resilient key can touch the ear of circlip for shaft opening, but can not touch the limit of circlip for shaft outmost turns.
Further, the groove footpath of described assembled shaft is slightly less than or equals the internal diameter of circlip for shaft.
Working principle of the present invention: no matter assembled shaft forward is still reversed, the ear of circlip for shaft opening always touches the resilient key being arranged on assembling shell, interaction between the two will make circlip for shaft opening inwardly shrink, thereby circlip for shaft is in the groove of assembled shaft all the time, guarantees that it loose or dislocation can not occur; Compared with the prior art, the large I in assembled shaft groove groove footpath is slightly less than or equals the internal diameter of circlip for shaft simultaneously.The present invention is applicable to limit assembled shaft axial motion with circlip for shaft, but must prevent that assembled shaft circlip for shaft in rotation process from the tools structure of wearing and tearing and loose or dislocation occurring.
Beneficial effect: the present invention prevents that circlip for shaft from becoming flexible and reducing the structure of its wearing and tearing, due to drive fit not between circlip for shaft and assembled shaft, so frictionalwear degree between the two can reduce greatly, prevent circlip for shaft loose or dislocation from assembled shaft groove, thereby extended largely the working life of instrument.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of one embodiment of the invention.
Fig. 2 is the blast structural representation of one embodiment of the invention.
Fig. 3 is assembled shaft forward structural representation in the present invention.
Fig. 4 is assembled shaft inversion structures schematic diagram in the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated: the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed mode of execution and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
Embodiment:
As depicted in figs. 1 and 2, figure comprises circlip for shaft 1, assembled shaft 2, resilient key 3, assembling shell 4, and circlip for shaft 1 is arranged in the groove of assembled shaft 2, the axial motion of restriction assembled shaft 2, but allow assembled shaft 2 to rotate.
The present invention, when the groove footpath of processing and assembling axle 2, should make the groove footpath of assembled shaft 2 be slightly less than or equal the internal diameter of circlip for shaft 1, and object is the wearing and tearing that reduce between assembled shaft 2 and circlip for shaft 1, extends the working life of instrument.
As shown in Figure 3, during assembled shaft 2 forward, the ear 11 of circlip for shaft 1 opening contacts with resilient key 3, and ear 11 contacts with resilient key 3 to occur to push circlip for shaft 1 opening is inwardly shunk, abut against in the groove of assembled shaft 2, and loose or dislocation phenomenon can not occur.
As shown in Figure 4, during assembled shaft 2 reversion, the ear 12 of circlip for shaft 1 opening contacts with resilient key 3, and ear 12 contacts same generation extruding and makes circlip for shaft 1 opening inwardly shrink and abut against in the groove of assembled shaft 2 with resilient key 3, also loose or dislocation phenomenon can not occur.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
