DETAILED DESCRIPTION

[0035] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as the limitation of the utility model.

[0036] Embodiment one

[0037] As Figures 1-6As shown, a water pump shell and washing machine mounting panel mounting structure, including water pump shell 1 and mounting panel 2 with mounting slot 3, mounting slot 3 is a hole structure through the mounting panel 2, the mounting slot 3 is a whole circular structure, the end of the tubular structure of the water pump shell 1 is inserted, the end face of the water pump shell 1 and the mounting panel 2 are provided with screw holes 4, the end of the water pump shell 1 towards the mounting panel 2 is provided with a pump shell end face 5 and a limiting structure, the screw hole 4 on the water pump shell 1 is located on the pump shell end face 5, the limiting structure is inserted into the mounting slot 3, the limiting structure and the pump shell end face 5 form an axial limiting groove 6 containing the mounting panel 2, so that the water pump shell 1 and the mounting panel 2 are axially limited, the side surface of the limiting structure is provided with a circumferential positioning surface 7 abutting the inner peripheral surface of the mounting slot 3, when the water pump shell 1 and the mounting panel 2 are axially and circumferentially limited to each other, the screw hole 4 of the water pump shell 1 is opposite to the screw hole 4 of the mounting panel 2.

[0038] The design of the axial limiting groove 6 clamps the mounting panel 2 between the limiting structure and the pump shell end face 5, so that the axial position of the drain pump 17 is stable, and the cooperation of the circumferential positioning surface 7 and the mounting slot 3 can determine the circumferential position of the water pump shell 1, and when the screw is installed, as long as the circumferential positioning surface 7 abuts the inner surface of the mounting slot 3, the screw hole 4 can be corresponded, compared with the traditional way which completely relies on manual holding alignment, the mounting structure of the utility model is more time-saving and labor-saving.

[0039] The limiting structure can be a deformable structure, which can limit or release the water pump shell 1 and the mounting panel 2 by deforming itself.

[0040] The limiting structure in the embodiment is achieved by position switching to limit or release the water pump shell 1 and the mounting panel 2. Compared with structural deformation, the position switching method can avoid simplifying the design and working form of the limiting structure and improve the service life of the limiting structure. The specific structure is that the limiting structure includes a mounting buckle 8, the mounting buckle 8 and the pump shell end face 5 form an axial limiting groove 6, and the circumferential positioning surface 7 is located on the side edge of the mounting buckle 8. The mounting slot 3 has a starting installation position 1001 for inserting the mounting buckle 8 into the mounting slot 3 and an end installation position 1002 for axially clamping the mounting buckle 8, and the mounting buckle 8 can switch between the starting installation position 1001 and the end installation position 1002. When the mounting buckle 8 is in the end installation position 1002, the mounting panel 2 is clamped in the axial limiting groove 6, and the side edge of the mounting buckle 8 abuts against the circumferential end face of the end installation position 1002.

[0041] The mounting buckle 8 is a fixed structure, the mounting panel 2 at the starting installation position 1001 is located outside the axial limiting groove 6 and does not have an axial limiting effect, and the mounting panel 2 at the ending installation position 1002 is located in the axial limiting groove 6 and has an axial limiting effect, so that when the mounting buckle 8 reaches the ending installation position 1002, the positioning of the water pump shell 1 and the mounting panel 2 is completed. The above effect can be achieved in the following manner: the radial dimension of the mounting groove 3 at the starting installation position 1001 is greater than the outer diameter of the mounting buckle 8, and the radial dimension of the mounting groove 3 at the ending installation position 1002 is less than the outer diameter of the mounting buckle 8. That is, the axial limiting and the release of the limiting are achieved by changing the radial dimension of the mounting groove 3 at different circumferential positions.

[0042] The end of the water pump shell 1 usually has a circular tube 11, and the cover 18 of the drain pump 17 is blocked in the circular tube 11. When the drain pump 17 is installed with the mounting panel 2, the circular tube 11 extends into the mounting groove 3 and plays a simple positioning role. Therefore, the inner circumferential surface of the mounting groove 3 usually also has a circular arc segment 9 matched with the circular tube 11. The outer circumferential surface of the circular tube 11 is preferably provided with a plurality of reinforcing ribs 14, and the reinforcing ribs 14 are in contact with the circular arc segment 9. In the utility model, the mounting groove 3 also includes a mounting segment 10, and the starting installation position 1001 and the ending installation position 1002 are located at two ends of the mounting segment 10. The radial dimension of the circular arc segment 9 is less than the maximum radial dimension of the mounting segment 10, and the connecting surface of the circular arc segment 9 and the mounting segment 10 forms a limiting surface 12 matched with the circumferential positioning surface 7. As shown in the figure, in the mounting segment 10, the radial dimension of the slot at the starting installation position 1001 is greater than the radial dimension of the slot at the ending installation position 1002. The inner circumferential surface of the mounting groove 3 at the starting installation position 1001 is a circular arc surface, and the inner circumferential surface of the mounting groove 3 at the ending installation position 1002 is a plane. The radial dimension of the slot of the mounting segment 10 is greater than the radial dimension of the slot of the circular arc segment 9. The two ends of the mounting segment 10 are inwardly contracted and connected with the circular arc segment 9. The contraction position forms the limiting surface 12. The mounting buckle 8 moves in the mounting segment 10. As shown in the figure, when the mounting buckle 8 reaches the ending installation position 1002, the left limiting surface 12 of the upper mounting segment 10 is in abutment with the circumferential positioning surface 7 on the mounting buckle 8. Figure 6 Figure 1

[0043] The position switching of the mounting buckle 8 between the starting installation position 1001 and the ending installation position 1002 can be achieved by different movement tracks, such as an arc-shaped movement track, a straight-line movement track or other irregular movement rules. In the embodiment, the drain pump 17 is preferably rotated with the center axis unchanged under the preliminary positioning of the circular tube 11 and the circular arc segment 9 of the mounting groove 3. The mounting buckle 8 also rotates with the drain pump 17. The starting installation position 1001 and the ending installation position 1002 are continuously arranged along the circumference. When the water pump shell 1 is rotated, the mounting buckle 8 can be switched between the starting installation position 1001 and the ending installation position 1002. ​​

[0044] When the installation buckle 8 enters the initial installation position 1001, the pump shell end surface 5 will abut against the outer end surface of the installation panel 2, then the water pump shell 1 is rotated, the installation buckle 8 is moved from the initial installation position 1001 to the terminal installation position 1002, during the rotation, the installation groove 3 cooperates with the circular tube 11 to ensure the center stability, the installation panel 2 is gradually clamped into the axial limiting groove 6 until the circumferential positioning surface 7 of the installation buckle 8 abuts against the limiting surface 12 on one side of the terminal installation position 1002.

[0045] The installation buckle 8 is arranged in one-to-one correspondence with the installation section 10, in order to ensure the stable limiting, the installation buckle 8 is arranged with two or more than two, in the embodiment, the installation buckle 8 is symmetrically arranged with two, the installation section 10 is also arranged with two in correspondence, the adjacent installation sections 10 are connected through the circular arc section 9.

[0046] When the installation panel 2 is located in the axial limiting groove 6, the installation panel 2 and the water pump shell 1 are preferably in interference fit in the axial direction, after the interference fit, the two can be kept relatively fixed in position without large external force, therefore, the accurate positioning can be realized through the axial interference fit and the unilateral circumferential limiting, and the screw installation can be completed without hand holding. The specific structure design requirement is that the axial thickness H2 of the installation panel 2 and the axial height H3 of the axial limiting groove 6 meet the following requirements: 0.5mm<H3<H2. For example, Figure 6 and Figure 7 As shown in the front view and the top view of the washing machine shell where the installation panel 2 is located, the installation panel 2 is a thin plate structure at the end, which can be inserted into the axial limiting groove 6, in the embodiment, the axial thickness H2 of the installation panel 2 is 0.7mm, and the axial height H3 of the axial limiting groove 6 is 0.6mm.

[0047] Embodiment two

[0048] On the basis of the above embodiment, in order to make the installation panel 2 more easily rotate into the axial limiting groove 6 and avoid the interference and jamming of the installation panel 2 and the lateral surface of the installation buckle 8, a chamfer 13 is arranged between the end surface of the installation buckle 8 facing the axial limiting groove 6 and the lateral surface of the installation buckle 8, the chamfer 13 gradually expands outward from the end surface of the installation buckle 8 to the lateral surface of the installation buckle 8. As shown in the figure, Figure 2 After the drainage pump 17 is loaded into the initial installation position 1001, the drainage pump 17 is counterclockwise rotated, through the guidance of the chamfer 13 on the installation buckle 8 as shown in the figure, Figure 5 the drainage pump 17 can be easily rotated into the inside of the installation groove 3 of the installation panel 2.

[0049] The size of the chamfer 13 needs to consider the size of the mounting buckle 8, the guiding effect, and the stability after installation and other factors. In the case of a certain size of the mounting buckle 8, if the length of the chamfer 13 is too long, the interference fit surface area on the mounting buckle 8 will be reduced, the interference fit effect will be reduced, and the mounting panel 2 is easy to separate from the axial limiting groove 6. The inclination angle of the chamfer 13 is too small or too large, which will cause the guiding effect to be reduced. Therefore, in this embodiment, the inclination angle C of the chamfer 13 relative to the end face of the mounting buckle 8 is 30°-45°, and the projection length H1 of the chamfer 13 on the end face of the mounting buckle 8 is 1mm-1.5mm.

[0050] Embodiment three

[0051] On the basis of the above-mentioned embodiments, the limiting structure further comprises an elastic buckle 15 mounted on the pump shell end face 5. When the mounting buckle 8 is in the initial installation position 1001, the elastic buckle 15 is extruded by the outer surface of the mounting panel 2. When the mounting buckle 8 is in the terminal installation position 1002, the elastic buckle 15 enters the initial installation position 1001, and the mounting buckle 8 and the elastic buckle 15 are respectively located on the circumferential end face of the initial installation position 1001 and the terminal installation position 1002.

[0052] The difference between this embodiment and embodiments one and two is that the water pump shell 1 and the mounting panel 2 are improved from single-side circumferential limiting to double-side circumferential limiting. As shown in Figure 3 , the circumferential positioning surface 7 is arranged on the mounting buckle 8 and the elastic buckle 15. When the mounting buckle 8 is located at the terminal installation position 1002, the circumferential positioning surface 7 on the mounting buckle 8 can inhibit the counter-clockwise rotation of the drainage pump 17, and the circumferential positioning surface 7 on the elastic buckle 15 can inhibit the clockwise rotation of the drainage pump 17 (as shown in Figure 1 ).

[0053] The elastic buckle 15 refers to a buckle that can elastically stretch and contract, specifically referring to a buckle that can stretch and contract along the axial direction of the water pump shell 1. When the elastic buckle 15 is extruded by the outer surface of the mounting panel 2, the elastic buckle 15 contracts inwardly to the pump shell end face 5. At this time, the elastic buckle 15 does not protrude out of the pump shell end face 5. When the elastic buckle 15 enters the initial installation position 1001, the elastic buckle 15 is reset to protrude out of the pump shell end face 5. At this time, the circumferential positioning surface 7 of the elastic buckle 15 is located on the limiting surface 12 on the side where the initial installation position 1001 is located. When it is necessary to release the circumferential limiting, press the elastic buckle 15 and rotate the drainage pump 17 clockwise to make the mounting buckle 8 return to the initial installation position 1001 again.

[0054] The circumferential positioning surface 7 on the water pump shell 1 is preferably closely attached to the limiting surface 12 on the mounting panel 2, that is, the distance H4 between the circumferential positioning surface 7 on the mounting buckle 8 and the limiting surface 12 on one side of the terminal mounting position 1002 is 0, and the distance H5 between the circumferential positioning surface 7 on the elastic buckle 15 and the limiting surface 12 on one side of the starting mounting position 1001 is 0, so that the drainage pump 17 cannot rotate and move clockwise or counterclockwise, at this time, the four screw holes 4 of the water pump shell 1 are coincided with the four screw holes 4 of the mounting panel 2, so that the four screws can be accurately screwed in turn without hand holding, time and labor are saved, and accurate positioning can be achieved.

[0055] In a further arrangement, the side end surface of the elastic buckle 15 opposite to the circumferential positioning surface 7 is a slope surface 16 (as shown in the figure). Figure 3 The slope surface 16 can not only reduce the friction between the elastic buckle 15 and the outer end surface of the mounting panel 2, but also increase the surface area of the elastic buckle 15, so that the elastic buckle 15 is convenient to press.

[0056] Embodiment four

[0057] A washing machine comprises a drainage pump 17 and a mounting panel 2, and the drainage pump 17 and the mounting panel 2 are fixedly assembled through the water pump shell and the mounting structure of the washing machine mounting panel described above.
