The specific embodiment
For the defect existing in prior art, the purpose of this utility model is to provide a kind of emulsion pumps, simple in structure, easy to assembly, reduce productive costs, between each accessory, can assemble in advance, improved productivity effect, wherein head can screw sealing with locking closure in obsolete situation, guarantees that liquid can not flow out external contamination environment.Below in conjunction with Figure of description, the utility model is described in detail.
As depicted in figs. 1 and 2, the emulsion pumps that the utility model provides, comprise head 1, locking closure 2, thread enclosing cover 3, the pump housing 4 and pipette 10, the pump housing 4 upper ends are provided with annular lip, internal step scalariform hollow, thread enclosing cover 3 is sleeved on the pump housing 4 upper ends from top to bottom along the longitudinal axis of the pump housing 4, locking closure 2 snap fasteners are combined in the pump housing 4 upper ends and thread enclosing cover 3 are rotated between spacing and locking closure 2 and annular lip, annular lip has pad 11, pad 11 is inserted in pump housing upper end from bottom to top along the longitudinal axis of the pump housing 4, and pad 11 can play the effect of excellent sealing.
The pump housing 4 upper ends are provided with head 1, in the pump housing 4, be provided with cylinder assembly, cylinder assembly is comprised of principal post 5, piston 6 and subpost 7, principal post 5 inner hollow, the lower end outer wall of principal post 5 is provided with annular overhead gage, the outer rim of annular overhead gage is protruded formation extension downwards, between the lateral wall of extension and principal post 5, form chute, subpost 7 is installed on principal post 5 lower ends from bottom to top, subpost 7 inner hollow and sealing bottom surface, sidewall is provided with circular hole, and subpost 7 both sides, lower end are provided with expansion mouth, and the lower end of subpost 7 is provided with annular lower baffle plate.Piston 6 comprises piston main body cylindraceous and is arranged on the arc flange on the lateral surface of piston main body, piston main body is slidably arranged on subpost 7, and and chute between form gap, the upper end wall thickness of piston main body is less than the width of chute, and the height of piston main body is less than the distance between annular overhead gage and annular lower baffle plate.In the process of the whole emulsion pumps of assembling, cylinder assembly can assemble in advance, and the cylinder assembly assembling packs the pump housing 4 inside into along the pump housing 4 longitudinal axis upper ends, easy to assembly, can greatly enhance productivity.
