Abstract
The utility model relates to an end cover which comprises a cover body, wherein the cover body is designed to be disc-shaped; a groove is formed in the middle of the cover body; six mounting holes are annularly arrayed at the periphery of the groove of the cover body; the mounting holes are designed as countersunk threaded holes. According to the end cover, the mounting holes used for mounting and fixing the end cover are the countersunk threaded holes and are annularly arrayed at the periphery of the groove of the cover body, so that the end cover can be screwed into the countersunk threaded holes by screws when in use, the top of each screw is in close contact with the end part of a rotary shaft, the end part of each screw is propped against a step of each countersunk threaded hole, an action point for fixing the part between the end cover and the rotary shaft is dispersed, and a tightening action force between the end cover and the rotary shaft is further increased; meanwhile, the end parts of the used screws are positioned in the countersunk threaded holes, so that the external environment influence is effectively avoided and the effect of fixing the part between the end cover and the rotary shaft is guaranteed.
Description
Technical field
The utility model relates to a kind of end cap, is specifically related to a kind of end cap be applied in rotating shaft.
Background technique
End cap is a kind of outer end that is fixed on component, with the component that play a protective role; Wherein, to being applied in the end cap in rotating shaft, structure used in the prior art is generally at the middle part of end cap and offers mounting hole, matches with the hole of roller end in the process of using, and is screwed, to play the protective action of countershaft end; The end cap of this structure is in the process of using, and the fixation point between end cap and rotating shaft is single, forms not ideal enough to the fastening effect power effect between end cap and rotating shaft; It is installed and fixes with screw simultaneously, and the end of the screw used is positioned at the outside of end cap, is vulnerable to the impact of external environment condition, thereby has reduced further the fastening effect between end cap and rotating shaft.
The model utility content
The utility model purpose is that a kind of end cap be applied in rotating 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 end cap, comprise lid, and described lid is arranged to discoid, and has in the middle groove; Described lid is shown some mounting holes at the surrounding circular array of groove, and described mounting hole is arranged to the countersunk head tapped hole.
Further, described lid is provided with rounding in the end of groove.
Further, described lid is shown 6 mounting holes at the surrounding circular array of groove.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
End cap described in the utility model, it is the countersunk head tapped hole for the fixedly mounting hole of end cap is installed, and annular array is in the surrounding of lid groove, this makes end cap in the process of using, can be screwed into respectively in the countersunk head tapped hole with screw, make the top of screw and the end close contact of rotating shaft, and the end of screw is kept out on the step of countersunk head tapped hole, this has not only disperseed for the fixing point of action between end cap and rotating shaft, and has further improved the fastening effect power between end cap and rotating shaft; The end of the screw used is positioned at the countersunk head tapped hole, has effectively avoided being subject to the impact of external environment condition, and then has guaranteed the fixation between end cap and rotating shaft simultaneously.
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 end cap described in the utility model;
The plan view that accompanying drawing 2 is end cap described in the utility model;
Wherein: 1, lid; 2, groove; 3, mounting hole; 4, rounding.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1,2 is a kind of end cap described in the utility model, comprises lid 1, and described lid 1 is arranged to discoid, and has in the middle groove 2; Described lid 1 is shown some mounting holes 3 at the surrounding circular array of groove 2, and described mounting hole is arranged to the countersunk head tapped hole.
Wherein said lid 1 is provided with rounding 4 in the end of groove 2.
End cap described in the utility model, it is the countersunk head tapped hole for the fixedly mounting hole 3 of end cap is installed, and annular array is in the surrounding of lid 1 groove 2, this makes end cap in the process of using, can be screwed into respectively in the countersunk head tapped hole with screw, make the top of screw and the end close contact of rotating shaft, and the end of screw is kept out on the step of countersunk head tapped hole, this has not only disperseed for the fixing point of action between end cap and rotating shaft, and has further improved the fastening effect power between end cap and rotating shaft; The end of the screw used is positioned at the countersunk head tapped hole, has effectively avoided being subject to the impact of external environment condition, and then has guaranteed the fixation between end cap and rotating shaft simultaneously.
End cap described in the utility model in the process of using, when its lid 1 is shown 6 mounting holes 3 at the surrounding circular array of groove 2, using effect the best.
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)
