Technical Field

[0001] The utility model relates to a drainage pump, in particular to a combination of a lower pump body and a curved pipe of a drainage pump with adjustable angles. 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 with adjustable angle, which can be assembled without using glue, and the discharge end direction of the elbow can be changed at any time as needed to facilitate subsequent installation.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a combination of a lower pump body and an elbow of a drainage pump with adjustable angle, comprising: a lower pump body, having a drainage pipe protruding outward laterally by a predetermined length, the outer tube wall of the drainage pipe having an outer ring groove and an inner ring groove arranged around it, the outer ring groove being closer to the end of the drainage pipe, and the outer ring groove and the inner ring groove being separated by a predetermined distance, a sealing ring being sleeved on the outer ring groove; an elbow having two ends respectively defined as a connecting end and a discharge end, the connecting end and the axial direction of the discharge end being not parallel, the elbow being sleeved on the drainage pipe by the connecting end, and the sealing ring being against the inner wall of the elbow A sealing effect is formed; wherein the bent pipe has a plurality of hollow parts, the plurality of hollow parts correspond to the inner ring groove, and the inner ring groove is connected with the external space through the plurality of hollow parts; the utility model further comprises an elastic buckle, which has two interference arms, and the two interference arms have an elastic restoring force to return to the original position after being stretched out, the elastic buckle is buckled with the bent pipe and the two interference arms enter the plurality of hollow parts and interfere with the inner ring groove, the elastic restoring force of the two interference arms causes the two interference arms to move toward each other and clamp the inner ring groove, and the bent pipe is sleeved on the drain pipe by the elastic buckle in a manner that it can rotate but cannot axially disengage.

[0006] Among them, the drainage pipe has a protrusion protruding radially outward from its pipe wall; the connecting end of the bent pipe has a plurality of grooves, which are distributed in a fan shape along the end edge of the connecting end of the bent pipe, each of the grooves can accommodate the protrusion individually, and one of the plurality of grooves accommodates the protrusion.

[0007] The plurality of grooves are arranged along the inner wall of the connecting end of the curved pipe, but do not penetrate the wall of the connecting end of the curved pipe, so the plurality of grooves cannot be visually seen from the side of the connecting end.

[0008] There are two hollowed-out parts, and the two hollowed-out parts are located at two opposite sides of the curved pipe.

[0009] In this way, the utility model can be assembled without using glue, and the direction of the discharge end of the elbow can be changed at any time as needed to facilitate subsequent installation.

[0042] 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:

[0043] like Figures 1 to 6 As shown, the utility model uses the first preferred embodiment to illustrate a combination 10 of a lower pump body and a curved pipe of a drainage pump with adjustable angle, which is mainly composed of a lower pump body 11, a curved pipe 21 and an elastic buckle 31, wherein:

[0044] The lower pump body 11 has a drain pipe 12 that protrudes outward laterally to a predetermined degree. The outer tube wall of the drain pipe 12 has an outer ring groove 121 and an inner ring groove 122 arranged around it. The outer ring groove 121 is closer to the end of the drain pipe 12, and the outer ring groove 121 and the inner ring groove 122 are separated by a predetermined distance. A sealing ring 14 is sleeved on the outer ring groove 121.

[0045] The elbow 21 has two ends respectively defined as a connection end 22 and a discharge end 24. The axial directions of the connection end 22 and the discharge end 24 are not parallel. The elbow 21 is sleeved on the drain pipe 12 by the connection end 22, and the sealing ring 14 abuts against the inner wall of the elbow 21 to form a sealing effect. In the first embodiment, the connection end 22 and the discharge end 24 are sandwiched at 90 degrees.

[0046] The key points of this first embodiment are:

[0047] The curved tube 21 has two hollow portions 26 located at two opposite sides of the curved tube 21 . The two hollow portions 26 correspond to the inner annular groove 122 . The inner annular groove 122 is connected to the external space through the hollow portions 26 .

[0048] The elastic buckle 31 has two interference arms 32, and the two interference arms 32 have an elastic restoring force to return to the original position after being stretched out. The elastic buckle 31 is buckled with the curved pipe 21 and the two interference arms 32 enter the multiple hollow parts 26 to interfere with the inner annular groove 122. The elastic restoring force of the two interference arms 32 causes the two interference arms 32 to move toward each other and clamp the inner annular groove 122, and remain located in the multiple hollow parts 26 to interfere with the curved pipe 21. The curved pipe 21 is rotatably sleeved on the drain pipe 12 but cannot be axially disengaged due to the interference limit of the elastic buckle 31.

[0049] The structure of the first embodiment has been described above, and the operation state of the first embodiment will be described next.

[0050] like Figure 6 As shown, after the assembly is completed, since the sealing ring 14 is sealed in the outer ring groove 121 to form a sealing effect, the water in the drain pipe 12 and the curved pipe 21 will not flow out from the position of the sealing ring 14 to the inner ring groove 122.

[0051] Furthermore, since the elastic buckle 31 is clamped on the inner annular groove 122 by the two interference arms 32 extending into the two hollow parts 26, the connection end 22 of the curved pipe 21 cannot move axially relative to the drain pipe 12, so there will be no problem of falling off. However, at this time, the curved pipe 21 can rotate relative to the drain pipe 12 under the action of external force. This is because the elastic buckle 31 only provides a clamping and interference effect to ensure that the curved pipe 21 cannot move axially relative to the drain pipe 12, but does not interfere in the rotation direction. Therefore, external force can be applied to rotate the curved pipe 21 relative to the drain pipe 12. The state after rotation is as follows: Figure 7 shown.

[0052] In the aforementioned structure, the user can rotate the curved pipe 21 to make its discharge end 24 face the desired direction, so as to facilitate the subsequent connection with an external pipe (not shown) or other objects for drainage.

[0053] like Figure 8 As shown, the remaining structures of the drainage pump are assembled on the lower pump body 11 to obtain a usable finished product.

[0054] As can be seen from the above, the first embodiment can be assembled without using glue, and the direction of the discharge end 24 of the curved pipe 21 can be changed at any time as needed to facilitate subsequent installation.

[0055] like Figures 9 to 11 As shown, the utility model uses the second preferred embodiment to illustrate a combination 10' of a lower pump body and a curved pipe of a drainage pump with adjustable angle, which is mainly similar to the first embodiment mentioned above, except that:

[0056] The drain pipe 12' has a protrusion 125' protruding radially outward from the pipe wall.

[0057] The connecting end 22' of the elbow 21' has a plurality of grooves 225', which are distributed in a fan shape along the end edge of the connecting end 22' of the elbow 21'. Each groove 225' can accommodate the protrusion 125' separately, and one of the plurality of grooves 225' accommodates the protrusion 125'.

[0058] Furthermore, in the second embodiment, the plurality of grooves 225' are arranged along the inner wall of the connecting end 22' of the curved tube 21', but do not penetrate the tube wall of the connecting end 22' of the curved tube 21', and the plurality of grooves 225' cannot be visually seen from the side of the connecting end 22'. This is only a choice of method. If the plurality of grooves 225' penetrate the tube wall of the connecting end 22' of the curved tube 21', it is also covered by the patent scope of this case. Since this structure can be directly understood, it is no longer shown in the figure.

[0059] In the second embodiment, the angle of the elbow 21' relative to the drain pipe 12' can be fixed by the structure that the protrusion 125' is embedded in one of the grooves 225'. When the angle needs to be changed, the elbow 21' can be moved away from the drain pipe 12' by removing the elastic buckle 31', so that the plurality of grooves 225' are separated from the protrusion 125'. At this time, the elbow 21' can be rotated to the desired angle, and then the elbow 21' can be assembled with the drain pipe 12', so that the protrusion 125' is embedded in one of the grooves 225' again, and the elastic buckle 31' is assembled again, and the action of changing the angle of the elbow 21' is completed.

[0060] The rest of the structure and the effects that can be achieved in the second embodiment are similar to those of the first embodiment, and will not be described in detail again.

[0061] 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.

[0062] 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.
