Description
Technical field
The utility model relates to a kind of parts of pump, relates in particular to a kind of peristaltic pump pump head.
Background technique
Peristaltic pump is belong to displacement pump a kind of, and the distribution that is mainly used in fluid is carried.During the work of peristaltic pump pump head, by the roller rotation, the extruding elastic hose is by the elastic hose conveyance fluid.Existing peristaltic pump pump head all adopts single briquetting to push single flexible pipe to carry out conveyance fluid, in course of conveying, because the influence of briquetting, causes in the flexible pipe FLUID TRANSPORTATION unbalanced, and is even at a stage mass flow discrepancy, makes that last Fluid Volume error of carrying is big.
Summary of the invention
The purpose of this utility model is to provide a kind of conveying even, the peristaltic pump pump head that error is little.
In order to achieve the above object, the technical solution of the utility model is: a kind of peristaltic pump pump head, comprise the pump housing and the pump cover of fixedlying connected with the pump housing, and be rotatablely equipped with rotary roller in the pump housing, a side of described pump cover is hinged with first pressing plate; The opposite side of pump cover also is hinged with second pressing plate of tackling mutually with first pressing plate, and an end of first pressing plate has the arc section pressure surface and the face that baroclines; One end of second pressing plate also has the arc section pressure surface and the face that baroclines.
The other end of described first pressing plate links to each other by first bolt with pump cover; The other end of second pressing plate links to each other by second bolt with pump cover, and has first spring between first pressing plate and the pump cover; Also has second spring between second pressing plate and the pump cover.
Described pump cover both sides are rotatably connected to first rotating shaft and second rotating shaft respectively, and first pressing plate is hinged by first rotating shaft and pump cover; Second pressing plate is hinged by second rotating shaft and pump cover.
The two ends of described first rotating shaft all have first buckle, and the two ends of second rotating shaft also all have second buckle; The both sides of the pump housing all have first draw-in groove and second draw-in groove that is complementary with first buckle and second buckle.
Described first buckle and second buckle are semicircle buckle; First draw-in groove that is complementary with it and second draw-in groove are the circular arc draw-in groove.
Also be connected with turning handle in described first rotating shaft and second rotating shaft.
After adopting said structure, the pressing plate that has two corresponding layouts on the pump cover can push two flexible pipes simultaneously by two block pressur plates, and corresponding extruding forms complementation, makes conveyance fluid even, and error is little.
Description of drawings
Fig. 1 is a structure exploded perspective view of the present utility model;
Fig. 2 is the structure exploded perspective view of the utility model pump cover.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, 2, a kind of peristaltic pump pump head of the present utility model comprises the pump housing 1 and the pump cover 2 of fixedlying connected with the pump housing 1, is rotatablely equipped with rotary roller 3 in the pump housing 1, and a side of described pump cover 2 is hinged with first pressing plate 4; The opposite side of pump cover 2 also is hinged with second pressing plate 5 of tackling mutually with first pressing plate 4, and an end of first pressing plate 4 has arc section pressure surface 4-1 and the face 4-2 that baroclines; One end of second pressing plate 5 also has arc section pressure surface 5-1 and the face 5-2 that baroclines.
As shown in Figure 2, the other end of described first pressing plate 4 links to each other by first bolt 6 with pump cover 2; The other end of second pressing plate 5 links to each other by second bolt 7 with pump cover 2, and has first spring 8 between first pressing plate 4 and the pump cover 2; Also has second spring 9 between second pressing plate 5 and the pump cover 2.Can regulate first pressing plate 4 and second pressing plate 5 like this with the distance between the pump cover 2, simultaneously because the effect of first spring 8 and second spring 9 can prevent to damage by pressure flexible pipe so that first pressing plate 4 and second pressing plate 5 have the elasticity of trace when squeezing tube.
As shown in Figure 1, described pump cover 2 both sides are rotatably connected to first rotating shaft 10 respectively and second rotating shaft, 11, the first pressing plates 4 are hinged with pump cover 2 by first rotating shaft 10; Second pressing plate 5 is hinged with pump cover 2 by second rotating shaft 11.Easy to connect, use and install simple.
As shown in Figure 1, the two ends of described first rotating shaft 10 all have the first buckle 10-1, and the two ends of second rotating shaft 11 also all have the second buckle 11-1; The both sides of the pump housing 1 all have the first draw-in groove 1-1 and the second draw-in groove 1-2 that is complementary with the first buckle 10-1 and the second buckle 11-1.When like this pump cover 2 being connected with the pump housing 1, only need to rotate first rotating shaft 10 and second rotating shaft 11, the first buckle 10-1 is snapped in the first draw-in groove 1-1, and the second buckle 11-1 snaps in the second draw-in groove 1-2, be connected firmly, otherwise dismounting is also only to need rotation first rotating shaft 10 and second rotating shaft 11 to get final product.
As shown in Figure 1, the described first buckle 10-1 and the second buckle 11-1 are semicircle buckle; The first draw-in groove 1-1 and the second draw-in groove 1-2 that are complementary with it are the circular arc draw-in groove.Simple to operate, easy to make.
As shown in Figure 1, 2, also be connected with turning handle 12 in described first rotating shaft 10 and second rotating shaft 11.Simple to operate.
As shown in Figure 1, 2, when the utility model uses, only need with difference correspondence between the rotary roller 3 two flexible pipes to be installed at first pressing plate 4 and second pressing plate 5, the two ends of two flexible pipes are connected to a total delivery line by threeway respectively, when pushing, can push two flexible pipes simultaneously by two block pressur plates like this, two block pressur plates push two flexible pipes simultaneously, corresponding extruding forms complementation, makes that last total conveyance fluid is even, and error is little.
