Abstract
The utility model discloses a screw, include: screw cap, screw pole and screw lid, the screw cap is fixed on the screw pole, and screw cap upper surface to screw pole bottom is opened and is had the through -hole, screw cap cross section is orthohexagonal structure, and screw cap upper surface is opened and to be had the cross recess, the rotatable setting of screw lid is in on the screw cap, and the cross section of screw lid is the same with the cross section size of screw cap. In this way, the utility model discloses can directly maintain mechanical equipment, need not to unpack apart the part, simple structure, convenient to use.
Description
Technical field
The utility model relates to screw field, particularly relates to a kind of screw.
Background technique
Screw is the requisite component in machinery, can be good at playing the effect be fixedly connected with.Some machinery need to add oiling agent, with the linkage of motion parts in guarantee equipment, and maintain the various piece of equipment.But this needs to take some component apart and can complete, very inconvenience.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of screw, can directly maintain machinery, and without the need to taking part apart, structure is simple, easy to use.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of screw, comprising: screw cap, screw rod and screw cover; Described screw cap is fixed on described screw rod, and screw cap upper surface has through hole to screw rod bottom; Described screw cap cross section is regular hexagon structure, and screw cap upper surface has cross recess; Described screw cover is rotating to be arranged on described screw cap, and the cross section of screw cover is identical with the cross section size of screw cap.
Preferably, the upper surface place of keeping to the side of described screw cap is provided with fixing column, and the position of the corresponding fixing column of described screw cover is provided with circular hole, and circle hole sleeve is on fixing column.
The beneficial effects of the utility model are: the utility model can directly maintain machinery, and without the need to taking part apart, structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model a kind of screw one preferred embodiment screw cover when turning on;
Fig. 2 is the sectional structure schematic diagram of a kind of screw of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, screw cap; 2, screw rod; 3, through hole; 4, screw cover; 5, fixing column.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model is embodiment comprise:
A kind of screw, comprising: screw cap 1, screw rod 2 and screw cover 4; Described screw cap 1 is fixed on described screw rod 2, and screw cap 1 upper surface is provided with through hole 3 to screw rod 2 bottom, can instill oiling agent by through hole 3; Described screw cap 1 cross section is regular hexagon structure, and screw cap 1 upper surface has cross recess, can load onto screw by multiple method, easy to use; Described screw cover 4 is rotating to be arranged on described screw cap 1, and the cross section of screw cover 4 is identical with the cross section size of screw cap 1, dust can be prevented by through hole access arrangement, and the cross recess on screw cap 1 can be avoided to wear and tear in equipment use process.The upper surface place of keeping to the side of described screw cap 1 is provided with fixing column 5, and the position of the corresponding fixing column 5 of described screw cover 4 is provided with circular hole, and circle hole sleeve on fixing column 5, thus makes screw cover 4 can rotate around fixing column 5, realizes outwarding winding and closing of screw cover 4.
During use, can directly be screwed on by small wrench; Also first can to outward winding screw cover 4, then to be screwed on by word pincers or cross pincers, after installing, shut screw cover 4.When adding oiling agent, screw cover 4 of directly outwarding winding, adds oiling agent by through hole in equipment, is then shutting rotary cover 4.
The utility model can directly maintain machinery, and without the need to taking part apart, structure is simple, easy to use.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
