Axis arrangement and be mutually connected vertically with described drive shaft；
Described drive disk is provided centrally with a circular hole, and the edge of described drive disk is provided with a dividing plate；
Described disk is rotatablely connected with described circular hole, and described annular seal space is stretched into the end of described dividing plate
Sliding connection structure interior, that described dividing plate and the lower end composition of described annular seal space seal.
As preferred embodiments of the present invention, the sliding connection structure of described sealing includes being arranged on annular seal space
Lower end be provided with two it is close to being disposed with an arch to the circular groove of arrangement, in described circular groove
Block is sealed, described arch sealing block includes a circular arc sealing surface and a smooth seal face, described circular arc sealing surface
It is slidably connected with described circular groove, described smooth seal face is slidably connected with described dividing plate.
The present invention the pump with active clapboard the advantages of be：On-bladed designs, and structure is relatively simple, production
Cost is relatively low, and the poor active clapboard of intensity is used only as seal applications, and reliability is higher.

Embodiment
The preferred embodiments of the present invention are described in detail below, so that advantages and features of the invention can be more
It is easy to be readily appreciated by one skilled in the art, so as to make protection scope of the present invention on apparent clear and definite boundary
It is fixed.
The present invention the pump with active clapboard the advantages of be：On-bladed designs, and structure is relatively simple, production
Cost is relatively low, and the poor active clapboard of intensity is used only as seal applications, and reliability is higher.
As shown in Figure 1 and Figure 2, a kind of pump with active clapboard, including a feed tube 1, a drain pipe 2,
One pump housing 3 and a drive shaft 4, the drive shaft 4 are connected with the center rotating of the pump housing 3, should with activity every
The pump of plate also includes a drive disk 5 and an annular seal space 6；The annular seal space 6 is connected with the pump housing 3, the feed liquor
Pipe 1 and drain pipe 2 are arranged in the both sides of joint；
As shown in figure 3, the end set of the drive shaft 4 has a disk 41, the center of circle of the disk 41 is deviateed should
The axis of drive shaft 4 is arranged and is mutually connected vertically with the drive shaft 4；
As shown in figure 4, the drive disk 5 is provided centrally with a circular hole 51, the edge of the drive disk 5 is set
There is a dividing plate 52；
As shown in figure 1, the disk 41 is rotatablely connected with the circular hole 51, it is close that this is stretched into the end of the dividing plate 52
Seal in chamber 6, the dividing plate 52 and the sliding connection structure of the lower end composition sealing of the annular seal space 6.
Under the driving of the drive shaft 4, the drive disk 5 periodically can be put in the pump housing 3, so as to
The liquid that will periodically enter through feed tube 1, push the side of drain pipe 2 to, realize the function of pump.Can be with
It is clear to see that the structure of this pump with active clapboard is relatively simple, amount of parts is less, and zero
The regular shape of part, processing cost is higher, and quality dividing plate 52 the weakest is only used for separating feed tube 1
With drain pipe 2, it is not connected, therefore be easier to be fully sealed, reliability is higher.
As shown in Figure 1, Figure 2, Figure 5, the sliding connection structure of the sealing includes being arranged on the lower end of annular seal space 6
Two are provided with to the circular groove 61 of arrangement, being disposed with arch sealing in the circular groove 61
Block 7, the arch sealing block 7 include a circular arc sealing surface 71 and a smooth seal face 72, the circular arc sealing surface 71
It is slidably connected with the circular groove 61, the smooth seal face 72 is slidably connected with the dividing plate 52.
It is only the mentality of designing of some embodiments of the present invention above, in the case where system allows, this
Invention can expand to while external more functional modules, so as to extend its function to greatest extent.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited to
This, any change or replacement expected without creative work, should all cover in protection scope of the present invention
Within.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
