The direction of the other end, it is difficult to it is corresponding with the connecting portion on pressurized tank, cause the metal hose other end to be connect with pressurized tank tired
It is difficult；The third method：Metal hose both ends are both configured to loose joint form, can be used when connecting five-way pipe joint, but be used for
When directly being connect with the pump housing, the link position of the pump housing and metal hose need to be arranged to one with externally threaded boss, to the pump housing
Processing brings prodigious difficulty.
Invention content
A kind of automatic type self priming pump is provided utility model aims to solve the above problem of the existing technology,
Change metal hose and pump housing connection type, that is, improve efficiency of assembling, is also convenient for metal hose and forms connection with the pressurized tank,
It does not need again and processes boss on the pump housing for connecting, reduce the difficulty of processing of the pump housing.
What the above-mentioned technical purpose of the utility model mainly solved by the following technical programs：Automatic type self priming pump, packet
Pressurized tank, the pump housing and metal hose are included, described metal hose one end connects the pressurized tank, and the other end connects the pump housing,
The pump housing is inserted into one end setting plug division and male part, the plug division for being characterized in that the connection by metal hose pump housing
Connector, and formed and sealed with the pump housing, the male part makes the metal hose be formed with the pump housing with unification casting die
Connection.Change metal hose and pump housing connection type, that is, improves efficiency of assembling, be also convenient for metal hose and formed with the pressurized tank
Connection, and do not need and process boss on the pump housing for connecting, reduce the difficulty of processing of the pump housing.When assembly, as long as having on the pump housing
Connector, plug division is inserted into, and forms sealing, by the cooperation of male part and casting die, metal hose is made to be formed reliably with the pump housing
Connection, it is simple in construction, easy to disassemble and assemble.
As further improving and supplementing to above-mentioned technical proposal, the utility model uses following technical measures：In order to
So that casting die is bonded pump housing outer wall, is on the one hand conducive to improve assembly reliability, is on the other hand also beneficial to operate, improve effect
Groove is arranged on the wall body of the connector for rate, and the male part accommodates in a groove, and the casting die is fixed on by connector
On the pump housing, the inner surface of casting die is made to be bonded pump housing outer wall.
In order to facilitate processing and assembling, seal groove is set on the outer wall of the plug division, sealing is set in the seal groove
Part, the sealing element make the inner wall of the plug division and connector form sealing.
In order to facilitate production and processing, the male part is bulge loop.
In order to facilitate production and processing, also for convenient for assembly, the casting die is pressing plate, and the pressing plate passes through connector and institute
It states the pump housing and forms detachable connection.
It is convenient for assembly in order to make plug division that there is enough wall thickness, intensity is also improved, the outer diameter of the plug division is less than described
The outer diameter of metal hose main body section, the internal diameter of the plug division are less than the internal diameter of the metal hose main body section.
Since bulge loop near sites have more stress concentration point, it is used for resistance to stress to improve intensity, it is described to insert
The inner wall of socket part extends to metal hose main body section direction, to be at least more than bulge loop position.
The utility model has the advantage that：Change metal hose and pump housing connection type, that is, improve efficiency of assembling,
Facilitate metal hose and the pressurized tank to be formed to connect, and do not need and process boss on the pump housing for connecting, reduces adding for the pump housing
Work difficulty.When assembly, as long as having connector on the pump housing, plug division is inserted into, and forms sealing, passes through matching for male part and casting die
It closes, so that metal hose is formed with the pump housing and be reliably connected, it is simple in construction, easy to disassemble and assemble.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the utility model.
Fig. 2 is the partial enlarged view of the utility model.
Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment：As depicted in figs. 1 and 2, automatic type self priming pump, including pressurized tank 1, the pump housing 2 and metal hose 3, it is described
3 one end of metal hose connects the pressurized tank 1, and the other end connects the pump housing 2.
It is particular in that, one end setting plug division 31 of the connection by metal hose pump housing and male part 32 are described to insert
