Abstract
The invention discloses an end cover. The end cover comprises a cover body, wherein the cover body is set into a disc shape, and a groove is arranged at the middle part of the cover body; six installing holes are circularly arrayed on the cover body and at the periphery of the groove, and are arranged into countersunk-head thread holes. The end cover disclosed by the invention has the advantages that since the installing holes for installing and fixing the end cover are the countersunk-head thread holes and are circularly arrayed at the periphery of the groove of the cover body, in the use process of the end cover, screws can be respectively screwed into the countersunk-head thread holes, the tops of the screws are closely contacted with the end part of a shaft, and the end parts of the screws are blocked on steps of the countersunk-head thread holes, so that not only are action points between the end cover and the shaft dispersed, but also the fastening action force between the end cover and the shaft is further increased; and simultaneously, the end parts of the used screws are positioned in the countersunk-head thread holes, so that the influence of the external environment is effectively avoided and further the fixing action between the end cover and the shaft is guaranteed.
Description
Technical field
The present invention relates to a kind of end cap, be specifically related to a kind of end cap that is applied in the 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 the 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 the rotating shaft is single, forms not ideal enough to the fastening effect power effect between end cap and the rotating shaft; It is installed with screw and fixes simultaneously, and the end of employed screw 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 the rotating shaft.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of end cap that is applied in the rotating shaft.
Technical solution of the present invention is achieved in that a kind of end cap, comprises lid, and described lid is arranged to discoid, and has in the middle groove; Described lid circular array around groove is shown some mounting holes, 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 circular array around groove is shown 6 mounting holes.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
The described end cap of the present invention program, it is used for installing fixedly, and the mounting hole of end cap is the countersunk head tapped hole, and annular array is around the lid groove, this so that end cap in the process of using, can be screwed into respectively in the countersunk head tapped hole with screw, so that the end close contact of the top of screw and rotating shaft, and the end of screw is kept out on the step of countersunk head tapped hole, this has not only disperseed to be used for the fixedly point of action between the end cap and rotating shaft, and has further improved the fastening effect power between end cap and the rotating shaft; The end of employed screw is positioned at the countersunk head tapped hole simultaneously, has effectively avoided being subjected to the impact of external environment condition, and then has guaranteed the fixation between end cap and the rotating shaft.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of end cap of the present invention;
Accompanying drawing 2 is the plan view of end cap of the present invention;
Wherein: 1, lid; 2, groove; 3, mounting hole; 4, rounding.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2 is a kind of end cap of the present invention, comprises lid 1, and described lid 1 is arranged to discoid, and has in the middle groove 2; Described lid 1 circular array around groove 2 is shown some mounting holes 3, 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 of the present invention, it is used for installing fixedly, and the mounting hole 3 of end cap is the countersunk head tapped hole, and annular array is around lid 1 groove 2, this so that end cap in the process of using, can be screwed into respectively in the countersunk head tapped hole with screw, so that the end close contact of the top of screw and rotating shaft, and the end of screw is kept out on the step of countersunk head tapped hole, this has not only disperseed to be used for the fixedly point of action between the end cap and rotating shaft, and has further improved the fastening effect power between end cap and the rotating shaft; The end of employed screw is positioned at the countersunk head tapped hole simultaneously, has effectively avoided being subjected to the impact of external environment condition, and then has guaranteed the fixation between end cap and the rotating shaft.
End cap of the present invention is in the process of using, and its lid 1 is when circular array is shown 6 mounting holes 3 around groove 2, and using effect is best.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (3)
