It is bad, influence the service life of water pump；And pump case be damaged after also compare and be difficult to safeguard or can only directly scrap.
Invention content
The problem of existing in actual use for existing water pump pump casing design, the purpose of this utility model is to provide one
Kind intensity height and water pump pump case easy to install, manufacturing process is simple, is connected and fixed whole use that is reliable and not interfering with water pump
Service life.
To reach the purpose of this utility model, the water pump pump case that a kind of intensity of the utility model is high and easy to install includes pump
Shell ontology, respectively along the outwardly extending upper flange of upper and lower plane and lower flange of pump case ontology, the upper flange and lower flange
It is circumferentially spaced about to be equably provided with multiple bolts U-shaped mouth is installed, the both sides of the U-shaped mouth of the lower surface of the upper flange and under
The both sides of the U-shaped mouth of the upper surface of flange are provided with the limit protrusion for preventing connection bolt displacement, and the thickness of the U-shaped mouth is big
In the thickness of upper flange and lower flange.
Preferably, the lower surface of the U-shaped mouth on the upper flange and the lower surface of upper flange are in same plane, U-shaped mouth
Upper surface protrude from the upper surface of upper flange；The upper surface of U-shaped mouth and the upper surface of lower flange on the lower flange exist
The lower surface of same plane, U-shaped mouth protrudes from the lower surface of upper flange.
Further preferably, the engaging lug of multiple protrusions is provided on the pump case ontology.
Further preferably, the thickness of the upper flange and lower flange is less than the thickness of shell of pump case.
The utility model has the beneficial effects that the water pump pump case extends outward to form the lower planes of pump case ontology
Flanged structure, on flanged structure setting be bolted U-shaped mouth and be provided with bolt anti-skid structure, flanged structure and be bolted
U-shaped mouth and pump case ontology integrally casting shaping, are not necessarily to the machining process of rear end, and processing cost is low and efficient；Pump case is easy to install,
Integral strength is high and service life is unaffected.

Structural schematic diagram.
Specific implementation mode
In conjunction with the structure feature and advantage of attached drawing the utility model, details are as follows.
It is combined together with reference to Fig. 3 and Fig. 4, the intensity height and water pump pump case easy to install of an embodiment of the utility model
100 include pump case ontology 20, respectively along the outwardly extending upper flange 21 of the upper and lower plane of pump case ontology 10 and lower flange 22, institute
The circumferentially spaced about of upper flange 21 and lower flange 22 is stated equably to be provided with multiple bolts U-shaped mouth 23 is installed, referring to Fig. 5 and Fig. 6,
The both sides of the U-shaped mouth 23 of the both sides of the U-shaped mouth 23 of the lower surface of the upper flange 21 and the upper surface of lower flange 22 are provided with
The limit protrusion 232 of connection bolt displacement, the thickness of the U-shaped mouth 23 is prevented to be more than the thickness of upper flange 21 and lower flange 22
Degree.In a preferred embodiment, the lower surface of the U-shaped mouth on the upper flange 21 and the lower surface of upper flange 21 are same
One plane, the upper surface of U-shaped mouth protrude from the upper surface of upper flange 21；The upper surface of U-shaped mouth on the lower flange 22 with
In same plane, the lower surface of U-shaped mouth protrudes from the lower surface of upper flange 22 for the upper surface of lower flange 22；It is described with reference to Fig. 3
The engaging lug 25 of multiple protrusions is provided on pump case ontology 20.In another preferred embodiment, the upper flange 21 is under
The thickness of flange 22 is less than the thickness of shell of pump case.
When mounted, it is only necessary to can pump case and other component be subjected to fastening installation using bolt, be not necessarily to auger shell wire hole；Spiral shell
Bolt installs the edge part that U-shaped mouth is located at pump case, is easily installed operation；U-shaped mouth is equipped with bolt anti-skid structure, ensures the reliable of connection
Property.Further accordance with pump case job stability or other fixed demands, the engaging lug knot of protrusion can be set on pump case ontology
Structure will not destroy the pump case pump housing, easy to connect.
The lower planes of pump case ontology are extended outward to form flanged structure by the water pump pump case of the utility model, in flange knot
Setting is bolted U-shaped mouth and is provided with bolt anti-skid structure on structure, flanged structure and is bolted U-shaped mouth and pump case ontology one
Body casting and forming, is not necessarily to the machining process of rear end, and process costs are low and efficient；In addition flanged structure not only increases pump case
Integral strength, moreover, because flange mechanism is not a core component of pump working cavity, even if during the work time, bolt
Vibrations occur for bearing, abrasion will not influence working cavity, safeguard also more convenient；The whole service life of pump case will not be by
To influence.
The utility model is not limited to the embodiment described, and those skilled in the art is not departing from the utility model
Spirit is that still may make some modifications or changes, therefore the rights protection scope of the utility model is with claims in the open scope
