The technical scheme of the utility model is that: a self priming pump, including motor, pump cover, pump case, impeller, the pump bonnet is established in pump case one end and both locking connection and is formed the pump chamber, its characterized in that: at least one group of prying assemblies for prying the pump cover and the pump shell are arranged in the pump cover, and each prying assembly comprises a hinge seat, a prying plate and a push rod; the hinge seat is fixed on the inner wall of the pump cover, and the center of the pry plate is hinged on the hinge seat; an axial threaded hole is formed in the end face of the pump cover, the push rod is screwed in the axial threaded hole, and the inner end of the push rod extends into the pump cover and is in pushing contact with one end of the prying plate; the outer edge of the joint surface of the pump cover and the pump shell is also provided with a first prying port, the pump shell is correspondingly provided with a second prying port, and the other end of the prying plate extends outwards and is inserted between the first prying port and the second prying port.
By the structure, the utility model discloses an add the sled subassembly and realize that the quick sled between pump cover and the pump case is from dismantling, and not fragile part. In the dismounting process, the ejector rod is screwed inwards to extend to push one end of the prying plate, the prying plate rotates by taking the central hinge point as a fulcrum to drive the other end inserted between the first prying port and the second prying port to move reversely, so that the combining surface of the pump cover and the pump shell is pried away gradually, the dismounting process is convenient and simple without the help of other tools, and the operation is easy.
Further, self priming pump in, all fill up in first sled mouth, the second sled mouth and be equipped with rubber packing pad, two rubber packing pads press from both sides tightly respectively in sled board tip both sides, can seal first sled mouth, second sled mouth position department when self priming pump normal use.
Further, self priming pump in, all be connected with reset spring between the both ends of sled board and the pump cover inner wall, when the ejector pin is outward backed out and not with sled board top push away the contact, keep sled board return to balanced state through reset spring.
Further, in the self-priming pump of the present invention, the hinge seat and the pump cover are integrally formed.
Further, self priming pump in, the subassembly is moved to the sled is two sets of, and sets up about pump cover central symmetry, but both sides are applyed simultaneously and are moved the effort, realize both separation more evenly fast.
The utility model has the advantages that:
the utility model discloses effectively solved pump cover and pump case faying face too inseparable technical problem, can realize the quickly separating of pump cover and pump case, the flexible dismantlement of being convenient for has improved the dismantlement efficiency of pump cover, has avoided dismantling the in-process simultaneously because of the operation damage to pump cover, pump cover improperly etc..

Detailed Description
The present invention will now be further described with reference to the accompanying drawings:
referring to fig. 1 to 3, the self-priming pump of the present embodiment includes a motor, a pump cover 2, a pump casing 1, and an impeller, wherein the pump cover 2 is covered at one end of the pump casing 1, and the pump casing and the pump cover are connected in a locking manner to form a pump cavity. Be equipped with in the pump cover 2 and be used for prizing a set of prying subassembly that is used for prizing from pump cover 2 and pump case 1 at least, prying the subassembly and being two sets of, and set up about pump cover 2 centrosymmetric. The prying assembly comprises a hinge base 3, a prying plate 4 and a push rod 5.
The hinge base 3 is fixed on the inner wall of the pump cover 2, and the hinge base 3 and the pump cover 2 are integrally formed. The center of the prying plate 4 is hinged on the hinge base 3; and return springs 10 are connected between the two ends of the pry plate 4 and the inner wall of the pump cover 2. An axial threaded hole 6 is formed in the end face of the pump cover 2, the ejector rod 5 is arranged in the axial threaded hole 6 in a threaded mode, and the inner end of the ejector rod extends into the pump cover 2 and is in ejection contact with one end of the prying plate 4; the pump cover 2 is provided with a first prying port 8 on the outer edge of the joint surface of the pump shell 1, the pump shell 1 is provided with a second prying port 7 correspondingly, and the other end of the prying plate 4 extends outwards and is inserted between the first prying port 8 and the second prying port 7. All fill up in first sled mouth 8, the second sled mouth 7 and be equipped with rubber seal pad 9, two rubber seal pads 9 press from both sides tightly respectively in 4 tip both sides of sled board.
The working principle of the structure is as follows: when dismantling, remove the locking connection back between pump cover 2 and the pump case 1, this embodiment can inwards screw in ejector pin 5 and make its one end that constantly pushes away sled board 4 along the inside top of axial, because sled board 4 center is the pin joint, the sled board 4 other end that is located between first sled mouth 8, second sled mouth 7 can reverse the upset and give pump cover 2 an effort of keeping away from pump case 1 to prize pump cover 2 from pump case 1.
