Abstract
Description
Technical Field
[0001] This utility model relates to the field of rear flange positioning mechanisms, and more particularly to a rear flange positioning mechanism for the inner drum of a washing machine. Background Technology
[0002] The inner drum of a washing machine is one of its core components. It comes into direct contact with clothes, is responsible for loading clothes, and provides the necessary mechanical movement during washing and spin-drying. The design of the inner drum usually takes into account the protection of clothes, and its surface is designed with many small holes. These holes allow water and detergent to flow freely during the washing process, while ensuring that water can be effectively drained during spin-drying.
[0003] Utility model CN217394162U discloses a positioning mechanism for the rear flange of a washing machine inner drum. This mechanism includes an assembly plate, a positioning plate, and a clamping assembly. The upper surface of the positioning plate has a receiving groove adapted to the rear flange. The clamping assembly includes a support and a cylinder and a pressure rod disposed on one side of the support. The upper surface of the support is stepped. The cylinder body is hinged to the support, and the piston rod of the cylinder is connected to one end of the pressure rod. The middle part of the pressure rod is hinged to the support. This utility model can stably clamp and position the rear flange in the inner drum rear flange assembly, providing a working environment for product pre-assembly and automated welding operations. However, this positioning mechanism has certain drawbacks. Because the positions of the assembly plate and the support are relatively fixed, the size of the rear flange clamped when clamping the washing machine inner drum rear flange is relatively limited, thus restricting its use.
[0004] Therefore, it is necessary to provide a new positioning mechanism for the rear flange of the inner drum of a washing machine to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figures 1-4 ,in, Figure 1 A schematic diagram of the structure of the washing machine inner drum rear flange positioning mechanism provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the bottom of the control panel. Figure 3 for Figure 1 A partial structural diagram of the structure shown; Figure 4 for Figure 1 The diagram shows a cross-sectional view of the structure.
[0022] In the specific implementation process, such as Figures 1-4 As shown, the assembly includes an assembly plate 1, an operating platform 2 mounted on the assembly plate 1, a drive device mounted on the inner side of the operating platform 2, and multiple movable plates 3 mounted on the drive device. The multiple movable plates 3 can move towards the center of the operating platform 2 under the action of the drive device. Two mounting platforms 4 are mounted on the movable plates 3, and a clamping plate 5 is mounted between the two mounting platforms 4. The clamping plate 5 can rotate. Two rows of pressure rings 6 are mounted on the side wall of the clamping plate 5. A slot 9 is opened in the middle of the two rows of pressure rings 6. A pressing block 7 is movably arranged in the slot 9. A spring 8 is also fixedly installed in the block. The end of the spring 8 is fixedly connected to the pressing block 7. The pressing block 7 can be completely moved into the slot 9. When the multiple pressure rings 6 press the rear flange, the pressing block 7 presses the rear flange under the action of the compressed spring 8, which improves the stability during pressing.
[0023] The drive unit includes a drive component, a driven bevel gear 11, a threaded rod 12, and two upright plates 13. The two upright plates 13 are fixedly installed on the inner wall of the operating platform 2.

The first motor 15 is fixedly connected, and the output end of the first motor 15 is fixedly connected to the driving bevel gear 16. The driving bevel gear 16 meshes with the driven bevel gear 11. The first motor 15 drives the driving bevel gear 16 to rotate. Since the driving bevel gear 16 meshes with the driven bevel gear 11, multiple driven bevel gears 11 rotate together. The driven bevel gears 11 drive the threaded rod 12 to rotate, thereby causing the movable plate 3 on the threaded rod 12 to move, realizing the position adjustment of the movable plate 3. This makes it convenient to adjust the position of multiple movable plates 3 according to the size of the rear flange.
