Abstract
The utility model relates to a connection shaft which comprises a shaft bottom and a shaft body, wherein the shaft body is arranged in the middle of the shaft bottom; a circular through hole is formed in the shaft body and penetrates through the shaft bottom; a plurality of installation holes are formed in the annular array of the shaft bottom; notches are formed in the positions, where the installation holes are located, of the shaft bottom, and the side edges, close to the circular through hole, of the notches are in an arc shape. Due to the fact that the notches are formed in the positions, where the installation holes are located, of the shaft bottom of the connection shaft, when the connection shaft is installed and fixed, the lengths, located on the connection shaft, of screws are shortened, namely, the lengths, screwed into a part needing to be acted on, of the screws are increased, and then the connection intensity between the connection shaft and the acted part by the screws is enhanced; meanwhile, the side edges, close to the circular through hole, of the notches are in the arc shape, so that in the process of the specific action on the screws, spiral screwing on screw heads of the screws by an external tool is not affected.
Description
Technical field
The utility model relates to a kind of component of machine, is specifically related to a kind of coupling shaft.
Background technique
The effect that is connected and fixed between the component of coupling shaft and required effect, its mounting hole on passing at the bottom of the coupling shaft axle by screw, then enter in the component of required effect, this has just determined that the intensity be connected and fixed between coupling shaft and component is that the length that enters into component inside by screw decides, need to reach high-intensity connection, this requirement to screw is higher, has certain narrow limitation.
The model utility content
The utility model purpose is that a kind of coupling shaft is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of coupling shaft, and at the bottom of comprising axle and axle body, described axle body is arranged on the middle part at the bottom of axle; Be provided with manhole on described axle body, and described manhole is through at the bottom of axle; On at the bottom of described axle, annular array has several mounting holes; Be provided with breach in the position at mounting hole place at the bottom of described axle, and described breach is arranged at the side near manhole circular-arc.
Further, on described axle body, be provided with circular groove, and described circular groove is arranged near the side at the bottom of axle, and overlaps with the lower surface at the bottom of axle.
Further, at the bottom of described axle, be provided with equably 4 mounting holes.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Coupling shaft described in the utility model, owing at the bottom of the axle in coupling shaft, in the position at mounting hole place, breach being set, make in it is installed to fixing process, shorten screw and be positioned at the length on coupling shaft, the length that is the screw component that enter into required effect is elongated, and then strengthens screw to the join strength between coupling shaft and the component that act on; Simultaneously described breach is arranged to circular-arcly at the side near manhole, like this in the process of screw being carried out to concrete effect, does not affect external utensil the screw head of screw is screwed.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The stereogram that accompanying drawing 1 is coupling shaft described in the utility model;
The stereogram that accompanying drawing 2 is the another kind of visual angle of coupling shaft described in the utility model;
Wherein: 1, at the bottom of axle; 2, axle body; 3, manhole; 4, mounting hole; 5, breach; 6, circular groove.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
A kind of coupling shaft described in the utility model shown in accompanying drawing 1,2, comprise at the bottom of axle 1 and axle body 2, and described axle body 2 is arranged at the bottom of axle 1 middle part; Be provided with manhole 3 on described axle body 2, and described manhole 3 is through at the bottom of axle 1; At the bottom of described axle on 1 annular array 4 mounting holes 4 are arranged; At the bottom of described axle, 1 is provided with breach 5 in the position at mounting hole 4 places, and described breach 5 is arranged to circular-arc at the side near manhole 3.
Be provided with circular groove 6 on wherein said axle body 2, and described circular groove 6 is arranged near a side of 1 at the bottom of axle, and overlap with 1 lower surface at the bottom of axle, make coupling shaft in the concrete process of using, can be at the interior sealing such as the seal ring object that arranges of the circular groove 6 of axle body 2, to improve the sealing of coupling shaft.
Coupling shaft described in the utility model, owing at the bottom of the axle in coupling shaft, 1 in the position at mounting hole 4 places, breach 5 being set, make in it is installed to fixing process, shorten screw and be positioned at the length on coupling shaft, the length that is the screw component that enter into required effect is elongated, and then strengthens screw to the join strength between coupling shaft and the component that act on; Simultaneously described breach 5 is arranged to circular-arcly at the side near manhole 3, like this in the process of screw being carried out to concrete effect, does not affect external utensil the screw head of screw is screwed.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
Claims (3)
