Abstract
The utility model discloses a single-stage pump, include: the pump body is provided with a plurality of screw holes, the pump cover is provided with a plurality of light holes, and the bolt penetrates through the light holes on the pump cover and is screwed into the screw holes on the pump body to connect the pump body with the pump cover; the utility model provides a do benefit to single-stage pump of other work piece installations and operations.
Description
Technical Field
The utility model belongs to the technical field of mechanical technique and specifically relates to a single-stage pump is related to.
Background
When the screw hole of the pump body is machined, machining depths are different, so that screw-in lengths of the studs are different, and after the studs are assembled, the lengths of threads exposed outside the nuts are different.
The Chinese patent with the publication number of CN203570568U discloses a pump body and pump cover connection structure, which comprises a pump body and a pump cover and is characterized in that the pump body and pump cover are provided with connecting studs, positioning nuts and fastening nuts, at least three connecting lug plates are uniformly distributed at the center of the periphery of the pump body, connecting through holes are formed in the connecting lug plates, at least three widened connecting plates are uniformly distributed at the periphery of the pump cover and fixedly connected with the pump cover through reinforcing ribs, so that the integral rigidity of the pump cover is improved, connecting threaded holes are formed in the outer ends of the widened connecting plates, the connecting studs penetrate through the connecting threaded holes and are fixedly connected with the pump cover through the positioning nuts, and the other ends of the connecting studs penetrate through the connecting through holes and are fixedly connected with the pump body through the positioning nuts.
The existing design structure integrates the pump body and the pump cover through the screw bolts and the nuts, and machining depth is different when the screw holes of the pump body are machined, so that screw bolts are different in screwing length, threaded length exposed outside the nuts is different after assembly, attractiveness of products is affected, and installation and operation of other workpieces are not facilitated.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a do benefit to single-stage pump of other work piece installations and operations, include: the pump comprises a pump body, a pump cover and bolts, wherein a plurality of screw holes are formed in the pump body, a plurality of light holes are formed in the pump cover, and the bolts penetrate through the light holes in the pump cover and are screwed into the screw holes in the pump body to connect the pump body with the pump cover.
Preferably, the screw holes have different depths.
Preferably, the bolt is a hexagon head bolt.
Preferably, the bolt is 3-10cm in length; further preferably, the bolt length is 5 cm.
The utility model discloses technical scheme is for prior art's beneficial effect: the utility model provides a do benefit to single-stage pump of other work piece installations and operations.
Drawings
Fig. 1 is a schematic structural view of a single-stage pump according to an embodiment of the present invention;
in the drawings: 1. pump body, 2, pump cover, 3, bolt.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Referring to fig. 1, a single-stage pump is shown, which includes a pump body 1, a pump cover 2, and bolts 3; the pump body 1 is provided with a plurality of screw holes, the pump cover 2 is provided with a plurality of light holes, and the bolt 3 passes through the light hole on the pump cover 2 and is screwed into the screw hole on the pump body 1, and connects the pump body 1 with the pump cover 2.
In the present embodiment, the bolt 3 is a hexagon head bolt.
In the present embodiment, the bolt 3 is 5cm in length.
To sum up, the utility model discloses a connect the pump body with the pump cover with specific bolt integratively, avoided because pump body screw depth of processing differs, cause the post-assembly product pleasing to the eye to do benefit to other workpiece setting and operation.
The above is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, and it should be appreciated by those skilled in the art that various equivalent substitutions and obvious changes made in the specification and drawings should be included within the scope of the present invention.
