[0001] This utility model relates to the field of metal casting technology, and more specifically to a deformation-resistant water pump housing. Background technology:

[0002] The main casing of existing water pumps is generally manufactured by casting. It usually has an inlet and an outlet. Depending on the design requirements, some inlets need to be long enough to connect with external equipment. However, the long inlet makes it easy for it to deform after long-term use due to gravity, causing the middle part to sink downwards and affecting its use. Utility Model Content:

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a deformation-resistant water pump housing. It has two clamping blocks installed at the left extension connector to fix and support the left extension connector, making it less prone to deformation and ensuring normal use.

[0004] The solution of this utility model to the aforementioned technical problem is:

[0005] A deformation-resistant water pump housing includes a main water pump housing and a cover. A right connector extending to the right is formed in the middle of the right side wall of the right side plate of the main water pump housing. An inner sleeve is provided inside the main water pump housing. A left extension connector extending to the left is formed in the middle of the left side wall of the left side plate of the main water pump housing. The right end of the left extension connector extends into the main water pump housing and is formed on the side wall of the inner sleeve and communicates with the middle cavity of the inner sleeve.

[0006] The outer wall of the left extension connector is formed with multiple axially protruding positioning strips extending left and right. A sleeve composed of two clamping blocks with a semi-circular cross-section is fixedly fitted on the outer wall of the left extension connector. The inner wall of the sleeve is in close contact with the outer wall of the left extension connector.

[0007] The upper, lower, front and rear parts of the outer side wall of the left extension connector are all formed with an axial protruding positioning strip. The inner side wall of the clamping block is an arc-shaped wall surface, which is closely attached to the corresponding outer side wall of the left extension connector. The axial protruding positioning strips of the front and rear are inserted into the left and right extending axial grooves formed on the inner side wall of the corresponding clamping block.

[0008] The upper and lower parts of the inner sidewalls of the two clamping blocks are formed with axially extending edge grooves, and the axially protruding positioning strips of the upper or lower parts are nested in the corresponding upper edge grooves or the corresponding lower edge grooves.

[0009] The upper surfaces of the two clamping blocks, which are close to each other, are formed with upwardly extending upper strip-shaped connecting plates. The two upper strip-shaped connecting plates are close together and fixedly connected by bolts.

[0010] The bottom surfaces of the two clamping blocks at their lower parts are formed with downwardly extending connecting parts. The two connecting parts are close together and fixedly connected by bolts. The bottom surfaces of the two connecting parts are formed with bottom connecting plates, and the two bottom connecting plates are close together.

[0011] The right end of the left extension connector communicates with the through hole in the middle of the left side plate of the inner sleeve.

[0012] The outer wall of the inner sleeve is a conical wall, with the outer diameter of the top being smaller than the outer diameter of the bottom.

[0013] Multiple right reinforcing ribs are formed on the outer side wall of the right connector, and multiple vertical reinforcing columns are formed on the left side wall of the radially extending edge formed on the outer side wall of the right end of the right connector. The right end of the right reinforcing rib is formed on the side wall of the corresponding vertical reinforcing column.

[0014] The top surface of the main housing of the water pump has a downwardly extending inner cavity formed in the middle, and the bottom surface of the inner cavity has an upwardly extending inner sleeve.

[0015] The top surface of the pump main housing surrounding the top of the inner cavity is formed with an upwardly extending upper positioning protrusion ring, and the bottom edge of the cover is formed with a bottom annular groove. The upper positioning protrusion ring is nested in the bottom annular groove, and the top surface of the upper positioning protrusion ring presses against the top surface of the bottom annular groove. The top surface of the pump main housing surrounding the upper positioning protrusion ring is formed with an annular groove, and a sealing ring is nested in the annular groove. The sealing ring is sandwiched between the bottom edge of the cover and the top surface of the pump main housing.

[0016] The bottom surface of the cover has an upward-extending frustum-shaped recess at the center of the inner cavity. The inner diameter of the top end of the frustum-shaped recess is smaller than the inner diameter of the bottom end. The frustum-shaped recess communicates with a vertical connecting through hole formed at the center of the top surface of the cover.

[0023] For example, see below. Figures 1 to 4 As shown, a deformation-resistant water pump housing includes a main water pump housing 10 and a cover 30. A right connector 11 extending to the right is formed in the middle of the right side wall of the right side plate of the main water pump housing 10. An inner sleeve portion 12 is provided inside the main water pump housing 10. A left extension connector 13 extending to the left is formed in the middle of the left side wall of the left side plate of the main water pump housing 10. The right end of the left extension connector 13 extends into the main water pump housing 10 and is formed on the side wall of the inner sleeve portion 12 and communicates with the middle cavity of the inner sleeve portion 12.

[0024] The outer wall of the left extension connector 13 is formed with multiple axially protruding positioning strips 131 extending left and right. The outer wall of the left extension connector 13 is fixedly fitted with a sleeve composed of two clamping blocks 20 with a semi-circular cross section. The inner wall of the sleeve is in close contact with the outer wall of the left extension connector 13.

[0025] The left extension connector 13 is supported and fixed by a sleeve composed of two clamping blocks 20, which makes it less prone to deformation and ensures normal use.

[0026] Furthermore, the upper, lower, front, and rear portions of the outer sidewall of the left extension connector 13 are each formed with an axially protruding positioning strip 131. The inner sidewall of the clamping block 20 is an arc-shaped wall surface, which is closely attached to the corresponding outer sidewall of the left extension connector 13. The axially protruding positioning strips 131 at the front and rear are inserted into the left and right extending axial grooves formed on the inner sidewall of the corresponding clamping block 20. The axially protruding positioning strips 131 position the clamping block 20, ensuring that its connection and fixing position is accurate.

[0027] The upper and lower parts of the inner sidewalls of the two clamping blocks 20 are formed with axially extending side grooves, and the axially protruding positioning strips 131 of the upper or lower parts are nested in the corresponding upper two side grooves or the corresponding lower two side grooves.

[0028] The upper surfaces of the two clamping blocks 20, which are close to each other, are formed with upwardly extending upper strip-shaped connecting plate portions 21. The two upper strip-shaped connecting plate portions 21 are close to each other and are fixedly connected by bolts.

[0029] The bottom surfaces of the two clamping blocks 20, near each other, are formed with downwardly extending connecting portions 22. The two connecting portions 22 are close together and fixedly connected by bolts. The bottom surfaces of the two connecting portions 22 are formed with bottom connecting plates 23, which are close together. The two bottom connecting plates 23 can be fixedly connected to the lower component by bolts, thereby supporting and fixing the left extension connector 13 between the two clamping blocks 20 and preventing deformation.

[0030] Furthermore, the right end of the left extension connector 13 communicates with the through hole in the middle of the left side plate of the inner sleeve 12.

[0031] The outer wall of the inner sleeve 12 is a conical wall, with the outer diameter of the top being smaller than the outer diameter of the bottom.

[0032] The outer wall of the right connector 11 is formed with a plurality of right reinforcing ribs 1, and the left side wall of the radially extending edge 111 formed on the outer wall of the right end of the right connector 11 is formed with a plurality of vertical reinforcing columns 2, the right ends of the right reinforcing ribs 2 being formed on the side wall of the corresponding vertical reinforcing columns 1. The right reinforcing ribs 2 and the vertical reinforcing columns 2 can improve the overall strength of the right connector 11 and prevent its deformation.

[0033] Furthermore, the top surface of the main housing 10 of the water pump has a downwardly extending inner cavity formed in the middle, and the bottom surface of the inner cavity has an upwardly extending inner sleeve portion 12 formed.

[0034] The top surface of the pump main housing 10 surrounding the top of the inner cavity is formed with an upwardly extending upper positioning protrusion ring 15, and the bottom edge of the cover 30 is formed with a bottom annular groove. The upper positioning protrusion ring 15 is nested in the bottom annular groove, and the top surface of the upper positioning protrusion ring 15 presses against the top surface of the bottom annular groove. The top surface of the pump main housing 10 surrounding the upper positioning protrusion ring 15 is formed with an annular groove, and a sealing ring is nested in the annular groove. The sealing ring is clamped between the bottom edge of the cover and the top surface of the pump main housing 10.

[0035] The bottom surface of the cover 30 has an upwardly extending frustum-shaped recess 31 formed at the center of the bottom surface facing the inner cavity. The inner diameter of the top end of the frustum-shaped recess 31 is smaller than the inner diameter of the bottom end. The frustum-shaped recess 31 communicates with a vertical connecting through hole formed at the center of the top surface of the cover 30. The frustum-shaped recess 31 communicates with the inner cavity of the inner sleeve 12 and the inner cavity of the pump main housing 10 on the outer side of the inner sleeve 12.

[0036] This embodiment can ensure the strength of the left extension connector 13 and the right connector 11, making them less prone to deformation and ensuring normal use.
