The case where.
And according to the assembly method of non-interference fit, then accordingly cause to have manufacturing procedure cumbersome and processing cost goes up
Disadvantage.
Utility model content
The purpose of this utility model is that providing a kind of application in order to overcome the deficiencies of the prior art has end cap fixed structure
Booster pump.
Using the booster pump for having end cap fixed structure, including being provided with the casing of opening and being connected to the end of the opening
Lid, the end cap match the joint portion for being open and being provided in central column, and the outer diameter at the joint portion is less than or equal to described open
The internal diameter of mouth, the joint portion is radially outwardly extending to be provided with several engagement rib, and the engagement rib is matched with the opening interference
It closes.
Further, the opening is rounded, and the joint portion is in annulus column.
Further, the engagement rib is provided at least 3.
Further, the engagement rib includes fixed block and bootstrap block interconnected, and the fixed block is located at close to institute
End cap side is stated, the side of the bootstrap block towards the opening inner wall is formed with the guidance junction for favouring joint portion, and institute
State guidance junction to the joint portion most short vertical range along the end cap side direction in increasing trend.
Further, the magnitude of interference range of the opening inside diameter of the engagement rib and the casing is 0.2~1.5mm.
The beneficial effects of the utility model are:
1, the end cap is improved while meeting end cap installation by the combination settings at joint portion and engagement rib
It is interference fitted the matching degree of installation, reduces the noise that generates by casing and end cap installation error, has that structure is simple, installation is high
The advantages of effect.
2, it is arranged by the guidance junction in the engagement rib, effectively guides corresponding end cap to be bonded to casing and complete interference
Cooperation.

Specific embodiment
In order to make the technical solution of the utility model, purpose and its advantage more clearly, below in conjunction with attached drawing and implementation
Example, is further explained explanation to the utility model.
As shown in Figures 1 to 4, a kind of application has the booster pump of end cap fixed structure, including pump head 1 and driving motor, institute
Stating driving motor includes: the casing 20 for being provided with upper opening and under shed, the upper end cover 21 for being connected to the upper opening and connection
In the lower cover 22 of the under shed, the upper opening is rounded, and the upper end cover 21 matches the upper opening and is provided with annulus
Columnar first joint portion 210, the outer diameter at first joint portion 210 are less than or equal to the internal diameter of the upper opening, and described first
210 lower edge of joint portion is radially outwardly extending to be provided with several first engagement rib 211, and first joint portion 210 passes through described
First engagement rib 211 is formed with the upper opening to be interference fitted.
It should be understood that in response to actual needs, the other shapes if upper opening is square etc., first joint portion 210
The central column for same shape can be matched, accordingly to meet the interference fit connection requirement of various forms of driving motors.
First engagement rib 211 is provided at least 3, and each first engagement rib 211 is outside first joint portion 210
Side is evenly arranged.
First engagement rib 211 includes fixed block interconnected and bootstrap block, and the fixed block is located at close to described
21 side of upper end cover, the side of the bootstrap block towards the upper opening inner wall, which is formed with, favours first joint portion 210
Guidance junction 3, and it is described guidance junction 3 to first joint portion 210 most short vertical range along the upper end cover 21 1
The direction of side is in increasing trend.
By being provided with inclined guidance junction 3 in 211 lower section of the first engagement rib, carried out when to the upper end cover 21
When pushing, which is able to guide first engagement rib 211 and smoothly accesses and generate deformation, to realize the upper end cover
It accesses in the upper opening of the casing 20 to 21 interference fits, meets the installation application demand of the upper end cover 21.
And in practical applications, first engagement rib 211 and the magnitude of interference range of the opening inside diameter of the casing 20 are
