Description

Technical Field

[0001] The utility model relates to the technical field of water pump shakers, in particular to an integrated injection-molded shaker of a split-type water pump. Background Art

[0002] A split-piece water pump is a water pump design that separates the pump body from the drive unit (usually an electric motor). This design facilitates installation, maintenance, and overhaul, and is widely used in agricultural irrigation, urban water supply, industrial water treatment, and drainage. In some split-piece water pumps, the shaker is a key component, converting the motor's rotational motion into reciprocating motion of the pump body, driving the piston or plunger to draw in and out liquid. The shaker design not only improves the pump's efficiency and stability, but also enables it to operate at lower speeds, enhancing its reliability and durability. Overall, split-piece water pumps and their shakers play a vital role in modern water systems.

[0003] At present, the shaker generally includes a base and a bearing. The base is formed by metal aluminum die-casting, and then a bearing cavity that matches the bearing is machined on the base. The bearing is then pressed into the bearing cavity by a press. Some shakers with upper covers also need to rivet the upper cover to the base. However, this split shaker has some disadvantages. For example, the metal aluminum die-casting method is expensive, and there are more processing links, which increases the production cycle and complexity. Secondly, the riveting and machining processes are prone to assembly tolerance problems, which affect the overall accuracy and performance of the shaker. In addition, metal aluminum is easily corroded during the use of the pump, which limits its service life. In addition, the heavy weight of the metal increases the load on the motor.

[0028] For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] Regarding the drawings of this application, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, this embodiment provides an integrated injection-molded shaker for a split-type water pump, including an integrated shaker, wherein the integrated shaker includes a plastic seat portion 1 and a bearing portion 2, and the two are injection-molded as one, which has lower production costs and a simplified production process. The integrated design improves assembly accuracy, reduces potential failure points, and at the same time reduces the overall weight, reduces the load on the motor, and improves energy efficiency. Among them, the bearing portion 2 is to use a bearing as an insert in the mold and is integrally injection-molded with the plastic seat portion 1 to form an integrated shaker. In this way, the plastic seat portion 1 is fixed to the outer ring of the bearing as a whole, and the inner ring can rotate freely. The integrated shaker has better integrity and strength.

[0032] In the disclosed embodiment, the bearing portion 2 includes an outer ring and an inner ring, and the circumferential outer side wall of the outer ring is provided with a tooth portion 200. In order to improve the bonding strength of the plastic seat portion 1 and the bearing portion 2 after integral injection molding, the bearing portion 2 adopts a bearing with an annular tooth on the outer ring. Preferably, the tooth portion 200 is a continuous convex tooth.

[0033] In the embodiment of the present disclosure, the plastic seat portion 1 includes a middle ring portion 10 and a plurality of connecting ears 11 evenly distributed along the outer circumference of the middle ring portion 10. In this embodiment, five connecting ears 11 are provided, and the middle ring portion 10 is provided with a mounting cavity 100. The connecting ears 11 are provided with a first connecting hole 110, and are usually connected to the water pump through the first connecting hole 110. Through this arrangement, the overall stiffness and strength of the shaker are enhanced, and it can better withstand the mechanical load during operation. At the same time, the uniform distribution of the connecting ears 11 improves the support stability.

[0034] In the embodiment of the present disclosure, a sinking groove 111 is provided at the front end of the connecting ear 11. The design of the sinking groove 111 can effectively reduce the weight of the connecting ear 11. The first connecting hole 110 is arranged in the sinking groove 111 and is eccentric to it, which is conducive to forming a stable assembly with the split water pump.

[0035] Optionally, a hollowed-out groove 112 is provided at the rear end of the connecting ear 11, and a connecting column 113 is formed corresponding to the first connecting hole 110. A reinforcing rib 114 is provided in a straight line between the outer wall of the connecting column 113 and the inner wall of the hollowed-out groove 112. The design of the hollowed-out groove 112 reduces the amount of material used and reduces the weight. In order to form the first connecting hole 110, the corresponding connecting column 113 is formed when the hollowing is required. The provision of the reinforcing rib 114 effectively enhances the structural strength of the connecting ear 11 and prevents deformation. Among them, the straight-line reinforcing rib 114 is more convenient to process. In addition, the longer first connecting hole 110 is also conducive to the assembly of the integrated shaker and the water pump.

[0036] In the embodiment of the present disclosure, the front end of the connecting ear 11 protrudes forward relative to the front end of the middle ring portion 10, and the rear end of the middle ring portion 10 protrudes backward relative to the rear end of the connecting ear 11. A cavity 13 is provided between adjacent connecting ears 11, which helps to reduce the overall weight and provide a certain degree of elasticity.

[0037] Secondly, the front outer edge of the connecting ear 11 is provided with an arc surface 115. The front end of the integrated shaker is generally in contact with the water pump housing or the engine cover. At the same time, a sealing gasket is provided at the contact position. The arc surface 115 can reduce damage to the sealing gasket.

[0038] In addition, the rear end of the mounting cavity 100 protrudes inward with a first annular step 1000, and the inner diameter of the first annular step 1000 is smaller than the outer diameter of the bearing part 2. Due to the one-piece injection molding, the bearing is also at risk of falling off during long-term use. Through the above arrangement, after the integrated shaker is assembled with the water pump housing or the machine cover, the bearing is further positioned, which further improves the stability of the bearing when the water pump is working.

[0039] Example 2:

[0040] like Figures 5 to 7 As shown, this embodiment provides another one-piece injection-molded shaker of a split-type water pump, including an one-piece shaker, the one-piece shaker including a plastic seat portion 1 and a bearing portion 2, and the two are integrally injection-molded. Compared with the first embodiment, the difference is that the plastic seat portion 1 includes a first annular seat 3 and a second annular seat 4, and the outer periphery of the first annular seat 3 is evenly provided with a plurality of first lugs 30. In this embodiment, three first lugs 30 are evenly provided, and the first lug 30 is provided with a second connecting hole 300. The second annular seat 4 is provided with a plurality of first lugs 30. A second lug 40 is provided on the outer periphery of the seat 4 corresponding to the first lug 30, and a through hole 400 is provided on the second lug 40 coaxially with the second connecting hole 300. A positioning protrusion 301 coaxial with the second connecting hole 300 is provided on the end surface of the first lug 30 facing the second lug 40, and a positioning groove 401 is provided on the second lug 40 for the positioning protrusion 301 to be embedded in. The design of the positioning protrusion 301 and the positioning groove 401 makes the positioning of the first annular seat 3 and the second annular seat 4 more accurate and the connection more firm and reliable during assembly.

[0041] In the embodiment of the present disclosure, a first guide portion 302 is provided at one end of the positioning protrusion 301 close to the second lug 40, and a second guide portion 402 is provided at one end of the positioning groove 401 close to the first lug 30, which is adapted to the first guide portion 302. The first guide portion 302 and the second guide portion 402 are adapted annular inclined surfaces to ensure that the positioning protrusion 301 is quickly embedded in the positioning groove 401.

[0042] Secondly, the first annular seat 3 includes a first cavity 31, and the second annular seat 4 includes a second cavity 41. The first cavity 31 and the second cavity 41 form a bearing cavity 5 adapted to the bearing. The rear end of the bearing cavity 5 protrudes inward with a second annular step 50. The inner diameter of the second annular step 50 is smaller than the outer diameter of the bearing part 2, and the inner diameter of the second cavity 41 is smaller than the outer diameter of the bearing part 2. Due to the one-piece injection molding, the bearing also has the risk of falling off during long-term use. Through the above arrangement, the stability of the bearing during water pump operation is improved, thereby improving the working performance of the water pump.
