Description
Technical field
The utility model relates to connecting component technical fields, more particularly, to a kind of axial restraint component.
Background technique
The shaft end fixation of Step Shaft is the general issues in Machine Design.In general, shaft end fixation can using nut,
The combination of shaft end ring, can also be using circlip, locking retaining ring, axial baffle etc..But use above-described fixation side
When formula, mount and dismount all very troublesome.Such as when using retaining ring, installation and removal require specific purpose tool, and need foot
Enough operating spaces, it is time-consuming and laborious.
Summary of the invention
The purpose of the utility model is to provide a kind of axial restraint components, it has, and assembly is simple, is not necessarily to installation tool, and
Lower feature is required assembly space.
The technical scheme adopted by the utility model is axial restraint component, including connecting shaft and connecting plate, the connecting plate
It is equipped with connecting hole, the diameter of the right part of the connecting shaft is equal to the internal diameter of the connecting hole, meanwhile, the right part edge of the connecting shaft
The connecting shaft circumferential surface be equipped with annular groove, between the left side wall of the groove and the bottom of the groove have angle α,
Between right side wall and the bottom of the groove have angle β, 60 °≤α≤90 °, 90 ° of β≤150 ° <, and, be arranged in the groove
There is " O " type rubber ring.
The left part edge of the connecting hole has horn mouth left large and right small.
The left part of the connecting shaft is equipped with step, and the spacing between the right side of the step and the left side wall of the groove is not small
In the thickness of the connecting plate.
The utility model is compared to the prior art advantageously: assembly is simple, is not necessarily to installation tool, and to assembly
Space requirement is lower.When in use, " O " type rubber ring acts as the work of connection card to the axial restraint component of the utility model
With, and during installation " O " type rubber ring be pressurized after convenient for connecting shaft from left to right pass through connecting hole, but dismantle when " O " type
Rubber ring can voluntarily fall off, and separate connecting shaft and connecting plate easily.In this way, even also can be complete in extremely narrow space
At assembly and disassembly, and do not need using any tool, it is extremely convenient.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:

Specific embodiment
Embodiment, as shown in Fig. 1 and Fig. 6: axial restraint component, including connecting shaft 10 and connecting plate 20, the connecting plate 20
It is equipped with connecting hole 21.In the present embodiment, the connecting hole 21 that passes through of the right part of the connecting shaft 10 from left to right is somebody's turn to do to realize
The connection of connecting shaft 10 and the connecting plate 20.
Further say:
The diameter of the right part of the connecting shaft 10 is equal to the internal diameter of the connecting hole 21.Meanwhile the right part edge of the connecting shaft 10
The connecting shaft 10 circumferential surface be equipped with annular groove 11.Have between the left side wall of the groove 11 and the bottom of the groove 11
Having has angle β, 60 °≤α≤90 °, 90 ° of β≤150 ° < between angle α, right side wall and the bottom of the groove 11.Preferable side
Formula is α=90 °, β=150 °.And " O " type rubber ring 30 is arranged in the groove 11.The section for being somebody's turn to do " O " type rubber ring 30 can
With semicircular in shape, and it is somebody's turn to do " O " type rubber ring 30 and can be intermittent hollow shape.That is, as shown in connection with fig. 7, along " O " the type rubber
The longitudinal direction of circle 30, every one section of spacing, being somebody's turn to do " O " type rubber ring 30 has a hollow cavity 31.
In conjunction with shown in Fig. 1 to Fig. 4, when needing to connect installation, first 30 sets of " O " the type rubber ring in the groove 11,
By the right part of the connecting shaft 10 from left to right pass through the connecting hole 21.Across when, should " O " type rubber ring 30 compressed, then
The right part that the connecting shaft 10 may be implemented passes through the connecting hole 21.After the completion of passing through, it is somebody's turn to do " O " type rubber ring 30 and restores former
Shape and ejecting card make the connecting shaft 10 and the connecting plate 20 realize connection on the right side of the connecting hole 21.As shown in connection with fig. 5, when
When needing to dismantle, pull the connecting shaft 10 to the left, due to the right side wall of the groove 11 be it is skewed, and 90 ° of β >, so drawing
In dynamic process, it should can deviate from out of this groove 11 after 30 vertical expansion of " O " type rubber ring, the connecting shaft 10 and the connecting plate 20
Smoothly disengage.In this way, easy for installation, reliable, particularly suitable installing and dismounting space is limited, and needs the work of frequent demolition and maintenance
Condition.Obviously, " O " the type rubber ring 30 with hollow cavity 31 is more suitable for and is compressed and smooth fallen off.Block piece as shown in the figure
100, it is relatively limited in order to illustrate the space of installation and removal.
Optimization:
The left part edge of the connecting hole 21 has horn mouth 211 left large and right small.In this way, convenient for should " O " type rubber ring 30
Gradually compressed.
The left part of the connecting shaft 10 be equipped with step 12, between the right side of the step 12 and the left side wall of the groove 11 between
Away from the thickness for being not less than the connecting plate 20.That is, the step 12 plays the role of limit.
It should be understood that
The utility model is only applicable to bear relatively small axial power or not by the shaft end fixation of the Step Shaft of axial force.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported
Used in other related technical areas, it is also included in the patent protection scope of the utility model.
