As shown in fig. 1 and 2, the eccentric structure of the present embodiment includes: the eccentric block 10, the eccentric block 10 has a through hole 100, the through hole has a first central axis 1, the circumferential outer wall of the eccentric block 10 encloses a structure having a second central axis 2, and the second central axis 2 has a predetermined angle with the first central axis 1.
By applying the technical scheme of the embodiment, the central shaft drives the eccentric block 10 to rotate when rotating, the eccentric block 10 drives the driven structure 40 to move along the direction of the central axis of the central shaft, that is, the rotation of the central shaft is converted into the axial movement of the driven structure 40, and the central axis of the central shaft coincides with the first central axis 1, so that the eccentric block 10 converts the rotation of the central shaft into the movement of the driven structure 40 along the direction of the central axis of the central shaft. The speed of the central shaft in the rotating process is uniform, and the operation is stable, so that when the eccentric block is applied to the pump, the water flow and the pressure of the pump are stable. The technical scheme of this embodiment has solved the unstable problem of rivers and pressure of pump among the prior art in the use effectively.
As shown in fig. 2 to 8, in the solution of the present embodiment, the first end surface of the eccentric mass 10 is perpendicular to the second central axis 2. The eccentric block 10 having the above structure is easy to manufacture. Of course, as a person skilled in the art knows, in the present embodiment, the first end surface of the eccentric block 10 forms an obtuse angle with the first central axis 1, and it is also possible that the included angle between the first end surface of the eccentric block 10 and the first central axis 1 is larger than the obtuse angle. Of course, as one skilled in the art will appreciate, the uneven configuration of the first end surface of the eccentric mass 10 may also be implemented to convert the rotation of the eccentric mass 10 into the axial movement of the driven structure 40.
As shown in fig. 1 to 4, in the solution of the present embodiment, a first end of the eccentric mass 10 is provided with a first step structure, and a step surface 200 of the first step structure is perpendicular to the first central axis 1. The structure that the step surface 200 of the first step structure is perpendicular to the first central axis 1 enables the eccentric block 10 to be conveniently forced when being matched with other parts. Specifically, when the first central axis 1 is in a horizontal position, when the central axis is mounted on the eccentric block 10, and an external support is abutted against the step surface 200 of the first step structure, the eccentric block 10 is only subjected to a force in the direction along the first central axis 1, these forces cancel each other out and, if the central shaft is mounted on the eccentric mass 10, the external support is pressed against the first end of the eccentric mass 10, since one force is in the direction of the first central axis 1, the other force is in the direction of the second central axis 2, the first central axis 1 and the second central axis 2 are at an angle, which inevitably results in that the two forces cannot be completely counteracted, that forces in other directions are required, when forces in other directions are generated between the central shaft and the eccentric mass 10, it is inevitable that the central shaft and the eccentric mass 10 are not easily mounted, and even abrasion between the central shaft and the eccentric mass 10 is caused. Therefore, when the step surface 200 of the first step structure is perpendicular to the first central axis 1, the problems that the eccentric block 10 is easy to be installed in cooperation with other parts and is not easy to wear can be reduced.
As shown in fig. 2 to 15, in the technical solution of the present embodiment, the eccentric structure further includes a radial protruding ring 20, the radial protruding ring 20 is disposed on the circumferential outer wall of the eccentric block 10 and forms a second step structure with the eccentric block 10, and a step surface 300 of the second step structure is perpendicular to the second central axis 2. The second step structure formed by the radial protrusion ring 20 is such that the second step structure forms a stop for the bearing 60 when the bearing 60 is mounted on the eccentric mass 10, so that the bearing 60 is not easily released from the eccentric mass 10. The step surface 300 of the second step structure is perpendicular to the second central axis 2, so that when the bearing 60 is installed on the eccentric block 10, the inner ring of the bearing 60 is combined with the circumferential outer wall of the eccentric block 10, the end surface of one side of the bearing 60 is abutted against the step surface 300 of the second step structure of the eccentric block 10, the bearing 60 is better attached to the step surface 300 of the second step structure, and the bearing 60 is uniformly stressed.
As shown in fig. 2 to 15, in the solution of the present embodiment, the eccentric structure further includes an axial convex ring 30, the axial convex ring 30 is disposed at the second end of the eccentric block 10, and the inner diameter of the axial convex ring 30 is larger than the inner diameter of the through hole 100. The provision of the axial collar 30 facilitates the mounting of the second end of the eccentric mass 10.
As shown in fig. 2 to 15, in the solution of the present embodiment, the end surface of the axial convex ring 30 is perpendicular to the first central axis 1. The above-described structure makes it convenient when the second end of the eccentric mass 10 is acted upon with a force parallel to the first central axis 1, in particular, when the central shaft is mounted under an axial force parallel to the first central axis 1, the end surface of the axial protrusion ring 30 is pressed against at this time so that the forces parallel to the first central axis 1 cancel each other without generating other component forces. The structure facilitates the assembly of the eccentric block 10 with other parts.
As shown in fig. 2 to 15, in the solution of the present embodiment, the outer diameter of the axial convex ring 30 is smaller than the outer diameter of the radial convex ring 20 so as to form a third step structure between the axial convex ring 30 and the radial convex ring 20, the step surface 400 of the third step structure is perpendicular to the second central axis 2, and the end surface of the radial convex ring 20 protruding from the axial convex ring 30 is perpendicular to the first central axis 1. The structure enables the bearing baffle 50 to be easily installed on the eccentric block 10, specifically, when the bearing 60 is installed on the eccentric block 10, the bearing baffle 50 is installed at the second end of the eccentric block 10, the driven structure 40 is installed at the first end of the eccentric block 10, the bearing 60 is installed between the bearing baffle 50 and the driven structure 40, and the bearing baffle 50 and the driven structure 40 limit the bearing 60 together with the eccentric block 10. The structure is convenient to install and compact. The step surface 400 of the third step structure is perpendicular to the second central axis 2, so that when the bearing 60 is installed, an external force is vertically applied to the step surface 400 of the third step structure, and the external force can be counteracted with an axial force generated by the bearing 60 and the eccentric block 10 without generating component forces in other directions, and the structure facilitates the installation of the bearing 60. The structure that the end face of the radial convex ring 20 protruding from the axial convex ring 30 is perpendicular to the first central axis 1 facilitates the installation of parts such as the bearing baffle 50. In the technical solution of this embodiment, the driven structure 40 includes a diaphragm base, an eccentric wheel, a diaphragm pressing plate, a high-pressure valve plate, a low-pressure valve plate, and the like.

The eccentric structure is matched with the flat position of the eccentric block 10 through a central shaft with the flat position, the inner ring of the bearing 60 is driven by the circumferential motion of the eccentric block 10 to do eccentric motion, the outer ring of the bearing 60 is tightly matched with the eccentric block 10, and the eccentric block 10 is limited in the circumferential direction, so that the up-and-down reciprocating motion of the eccentric wheel meets the requirements of product functions. Of course, as one skilled in the art will appreciate, other means of mating the central shaft and eccentric mass 10 using splines or the like are also possible.
