Description
Technical field
The utility model relates to a kind of parts of pump, particularly a kind of Peristaltic pump head.
Background technique
Peristaltic pump is the one belonging to displacement pump, is mainly used in the distribution conveying of fluid.During Peristaltic pump head work, rotated by roller, extruding elastic hose, carries fluid by elastic hose.Existing Peristaltic pump head all adopts single briquetting to extrude single flexible pipe to carry out conveying fluid, in course of conveying, due to the impact of briquetting, causes fluid conveying in flexible pipe unbalanced, even at a stage mass flow discrepancy, makes the Fluid Volume error of last conveying large.
Summary of the invention
The utility model technical issues that need to address are by roll wheel assembly cycle extrusion flexible pipe, utilize elastic hose to carry fluid, improve the stability of fluid conveying; A kind of Peristaltic pump head is provided.
For solving above-mentioned technical problem, structure of the present utility model comprises micro motor, speed reducer, pump head pedestal, roll wheel assembly and pump head upper cover, described micro motor is connected with speed reducer, the upper surface of described pump head pedestal is provided with cavity volume, described roll wheel assembly is movably connected in cavity volume, described speed reducer is connected with roll wheel assembly through pump head pedestal, the pump head pedestal of described cavity volume both sides also offers down tube seat, described pump head covers be provided with corresponding under go out tube seat corresponding matching on go out tube seat, go out under described tube seat with on go out tube seat and be connected with cavity volume.
Further: described roll wheel assembly comprises two flange plates, rotating shaft and group of rollers, two described flange plates are sleeved in rotating shaft, described group of rollers is connected between two flange plates, and one end of described rotating shaft is connected with speed reducer, and the other end of described rotating shaft is flexibly connected with pump head upper cover.
Further again: described group of rollers is made up of three rollers, three described rollers are that triangular is connected between adjacent two flange plates.
After adopting said structure, the utility model, by roll wheel assembly cycle extrusion flexible pipe, utilizes elastic hose to carry fluid, improves the stability of fluid conveying; And the design also has the advantage that structure is simple, be easy to manufacture and practicality and high efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural blast schematic diagram of the present utility model.
Embodiment
A kind of Peristaltic pump head as depicted in figs. 1 and 2, comprise micro motor 1, speed reducer 2, pump head pedestal 3, roll wheel assembly and pump head upper cover 5, described micro motor 1 is connected with speed reducer 2, the upper surface of described pump head pedestal 3 is provided with cavity volume 6, described roll wheel assembly is movably connected in cavity volume 6, described speed reducer 2 is connected with roll wheel assembly through pump head pedestal 3, the pump head pedestal 3 of described cavity volume 6 both sides also offers down tube seat 7, described pump head upper cover 5 is provided with corresponding under go out tube seat 7 corresponding matching on go out tube seat 8, go out under described tube seat 7 with on go out tube seat 8 and be connected with cavity volume 6.When needs carry out fluid conveying, first elastic hose is installed in cavity volume 6, elastic hose body is contacted with roll wheel assembly, the two ends of elastic hose respectively from two go out tube seat 8 and under go out between tube seat 7 to stretch out, then starting micro motor 1 makes it be rotated with roll wheel assembly by speed reducer 2, utilize roll wheel assembly to extrude elastic hose, carry out fluid conveying by elastic hose, improve the stability of fluid conveying; And the design also has the advantage that structure is simple, be easy to manufacture and practicality and high efficiency.
Roll wheel assembly as shown in Figure 2 comprises two flange plates 9, rotating shaft and group of rollers, two described flange plates 9 are sleeved in rotating shaft, described group of rollers is connected between two flange plates 9, and one end of described rotating shaft is connected with speed reducer 2, and the other end of described rotating shaft is flexibly connected with pump head upper cover 5; Described group of rollers is made up of three rollers 10, and described three rollers 10 are connected between adjacent two flange plates 9 in triangular.Starting micro motor 1 during work makes it be rotated with rotating shaft by speed reducer 2, utilizes rotating shaft together to rotate with two flange plates 9 and group of rollers, utilizes three rollers, 10 pairs of elastic hoses to carry out friction and Extrusion, thus carry out fluid conveying by elastic hose; The design extrudes elastic hose successively by three rollers 10 and carries out fluid conveying, thus ensure that the stability of fluid water outlet.
