Description

Technical Field

[0001] The utility model relates to a drainage pump, in particular to a combination of a lower pump body and a bent pipe of the drainage pump. Background Art

[0002] The Chinese patent publication CN 205078505U discloses a drainage pump and its lower pump body. The key technology is that one of the pipe of the lower pump body and the first end of the elbow is provided with a groove to hold glue, and the other is provided with a convex portion to be inserted into the groove and fixed by bonding. The purpose of this case is to solve the problem that glue is not airtight enough after bonding, or has large tolerance and poor quality.

[0003] After the elbow in the aforementioned case is assembled, the elbow can be used to change the water outlet direction of the lower pump body from the horizontal direction of the connecting pipe to the upward direction of the elbow. However, the result of such assembly is that the elbow can only be upward, with no other choice. Sometimes, it limits the assembly angle. If more flexible angles can be provided for users to choose, greater assembly convenience can be provided. Utility Model Content

[0004] The main purpose of the utility model is to provide a combination of a lower pump body and an elbow of a drainage pump, which can provide multiple options for the assembly angle of the elbow, so that the drainage direction can be adjusted according to user needs before assembly, providing more flexible assembly convenience.

[0005] The edge is, according to a combination of a lower pump body and a bent pipe of a drainage pump proposed by the utility model, comprising: a lower pump body, having a drainage pipe protruding outwardly laterally by a predetermined length; and a bent pipe, having two ends respectively defined as a connecting end and a discharge end, the connecting end and the axial direction of the discharge end are not parallel, the bent pipe is sleeved on the drainage pipe with the connecting end, and the connecting end of the bent pipe is bonded and fixed to the drainage pipe by a colloid; wherein the drainage pipe has a protrusion protruding radially outward from its pipe wall; in addition, the connecting end of the bent pipe has a plurality of grooves, the plurality of grooves are fan-shapedly distributed along the edge of the connecting end of the bent pipe, each of the grooves can accommodate the protrusion separately, and one of the plurality of grooves accommodates the protrusion.

[0006] Thus, the utility model can provide multiple options for the assembly angle of the elbow, so that the drainage direction can be adjusted according to the needs of the user before assembly, providing more flexible assembly convenience.

[0029] In order to explain the technical features of the present invention in detail, the following preferred embodiments are given and illustrated with reference to the accompanying drawings, wherein:

[0030] like Figures 1 to 5As shown, the utility model uses a preferred embodiment to illustrate a combination 10 of a lower pump body and an elbow of a drainage pump, which is mainly composed of a lower pump body 11 and an elbow 21, wherein:

[0031] The lower pump body 11 has a drainage pipe 12 that protrudes outward laterally to a predetermined length.

[0032] The curved pipe 21 has two ends, which are respectively defined as a connection end 22 and a discharge end 24. The axis of the connection end 22 and the discharge end 24 are not parallel. The curved pipe 21 is sleeved on the drain pipe 12 by the connection end 22, and the connection end 22 of the curved pipe 21 is bonded and fixed to the drain pipe 12 by a colloid 31. In this embodiment, the angle between the connection end 22 and the discharge end 24 is substantially 90 degrees. In addition, since the volume of the colloid 31 is very small, it is difficult to express. Figure 4 and Figure 5 The portion of the gap between the drain pipe 12 and the connecting end 22 is indicated in black.

[0033] The technical focus of this embodiment is:

[0034] The drain pipe 12 has a protrusion 121 protruding radially outward from the wall of the drain pipe 12 .

[0035] The connection end 22 of the curved pipe 21 has a plurality of grooves 221 , which are distributed in a fan shape along the end edge of the connection end 22 of the curved pipe 21 . Each of the grooves 221 can accommodate the protrusion 121 individually, and one of the grooves 221 accommodates the protrusion 121 .

[0036] In this embodiment, the distances between the two adjacent grooves 221 may be different, but in this embodiment, the distances are the same as an example. In addition, the protrusion 121 may protrude outward in any direction, but in this embodiment, it is taken as an example that it protrudes upward.

[0037] The structure of this embodiment is described above. Next, the combination state of this embodiment and the effects that can be achieved are described.

[0038] like Figure 2 As shown, before assembly, the outer wall surface of the drain pipe 12 is coated with the colloid 31 (shown in FIG. Figure 4 and Figure 5 ), and then the connecting end 22 of the elbow 21 is sleeved on the drain pipe 12, and the protrusion 121 is embedded in the groove 221 to form a positioning, and the assembly is completed after the colloid 31 is cured, and the structure is as follows Figure 1 status.

[0039] like Figure 6As shown, the remaining structures of the drainage pump are assembled on the lower pump body 11 to obtain a usable finished product.

[0040] For example Figure 7 As shown, if the discharge end 24 of the curved pipe 21 is facing one side before assembly, the assembly can also be completed in the above manner, and the protrusion 121 is embedded in the other groove 221 to form a positioning.

[0041] It is worth adding that the aforementioned plurality of grooves 221 are described by taking the pipe wall of the connecting end 22 of the curved pipe 21 as an example, but other structural changes are also possible, for example, Figure 8 As shown, the plurality of grooves 221' may also be arranged along the inner wall of the connecting end 22' of the curved pipe 21', but not penetrate the wall of the connecting end 22' of the curved pipe 21', so that the plurality of grooves 221' cannot be visually seen from the side of the connecting end 22'.

[0042] As can be seen from the above, the utility model can provide multiple options for the assembly angle of the elbow 21, so that the direction of the drainage end 24 of the elbow 21 can be adjusted according to user needs before assembly, and the discharge end 24 of the elbow 21 can be used to connect a hose for outward drainage. Therefore, the utility model provides more flexible assembly convenience.

[0043] The above is merely the content of the present invention described through the embodiments, and it cannot be used to limit the patent scope of the present invention. All simple changes or equivalent implementations made according to the patent scope of the present invention and the contents of the patent specification should be covered by the patent scope of the present invention.

[0044] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims of the present invention.
