Description

Technical Field

[0001] This utility model relates to the field of drum washing machine technology, and specifically discloses a top cover positioning structure for a drum washing machine. Background Technology

[0002] Currently, the installation and positioning structure of the top cover of a drum washing machine involves installing a mushroom-shaped nail on each of the left and right upper reinforcing plates on the cabinet. When the top cover is installed, the top cover clips are inserted into the mushroom-shaped nails to position the top cover and ensure the gap and step difference between the top plate and the cabinet. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a top cover positioning structure for a drum washing machine that can reduce the gap between the top cover and the cabinet and ensure that the top cover arches and deforms less.

[0004] According to the technical solution provided by this utility model, the top cover positioning structure of the drum washing machine includes a top cover and reinforcing plates fixed to the top left and right sides of the drum washing machine body, with the left and right sides of the top cover mounted on the corresponding reinforcing plates.

[0005] Hook bodies are fixed on the left and right sides of the lower surface of the top cover. The hook bodies are integrally connected to the top cover. A guide surface is provided at the upper front end of the hook body. The guide surface is an inclined surface with a lower front end and a higher rear end. A positioning surface is connected to the rear end of the guide surface. The plane of the positioning surface is parallel to the plane of the top cover. A stop surface is provided behind the positioning surface. The plane of the stop surface is perpendicular to the plane of the positioning surface. The upper end of the stop surface is above the positioning surface.

[0006] The reinforcing plate has hook mounting holes;

[0007] The hook body is installed in the hook mounting hole, the stop surface on the hook body is in contact with the front wall surface of the hook mounting hole, and the positioning surface on the hook body is in clearance fit with the lower surface of the reinforcing plate.

[0008] Preferably, the stop surface is positioned entirely above the positioning surface.

[0009] Preferably, the gap between the outer wall of the hook body and the outer wall of the corresponding hook mounting hole is smaller than the gap between the inner wall of the hook body and the inner wall of the corresponding hook mounting hole.

[0010] This invention can reduce the gap between the top cover and the casing and ensure that the top cover arches and deforms less. This invention uses a hook body instead of the mushroom nail in the prior art, which reduces the part cost of the drum washing machine and also reduces the production and installation cost.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A top cover positioning structure for a drum washing machine, such as Figure 1-8 As shown, it includes a top cover 1 and reinforcing plates 2 fixed to the top left and right sides of the drum washing machine body. The left and right sides of the top cover 1 are mounted on the corresponding reinforcing plates 2.

[0021] Hook bodies 1.1 are fixed on the left and right sides of the lower surface of the top cover 1. The hook bodies 1.1 are integrally connected to the top cover 1. The upper front end of the hook body 1.1 is provided with a guide surface 1.11, which is a sloping surface with a lower front end and a higher rear end. A positioning surface 1.12 is connected to the rear end of the guide surface 1.11. The plane of the positioning surface 1.12 is parallel to the plane of the top cover 1. A stop surface 1.13 is provided behind the positioning surface 1.12. The plane of the stop surface 1.13 is perpendicular to the plane of the positioning surface 1.12. The upper end of the stop surface 1.13 is above the positioning surface 1.12.

[0022] A hook mounting hole 2.1 is provided on the reinforcing plate 2;

[0023] The hook body 1.1 is installed in the hook mounting hole 2.1. The stop surface 1.13 on the hook body 1.1 is in contact with the front wall surface of the hook mounting hole 2.1, and the positioning surface 1.12 on the hook body 1.1 is in clearance fit with the lower surface of the reinforcing plate 2.

[0024] The stop surface 1.13 is located entirely above the positioning surface 1.12.

[0025] The gap between the outer wall of the hook body 1.1 and the outer wall of the corresponding hook mounting hole 2.1 is smaller than the gap between the inner wall of the hook body 1.1 and the inner wall of the corresponding hook mounting hole 2.1. Specifically, the gap between the left wall of the left-side hook body 1.1 and the left wall of the left-side hook mounting hole 2.1 is smaller than the gap between the right wall of the left-side hook body 1.1 and the right wall of the left-side hook mounting hole 2.1; and the gap between the right wall of the right-side hook body 1.1 and the right wall of the right-side hook mounting hole 2.1 is smaller than the gap between the left wall of the right-side hook body 1.1 and the left wall of the right-side hook mounting hole 2.1. This ensures that the top cover 1 can only move within a small range in the left-right direction, thus minimizing the step difference between the top cover 1 and the drum washing machine body.

[0026] During installation, the hook body 1.1 is inserted into the hook mounting hole 2.1 of the corresponding reinforcing plate 2 via its guide surface 1.11. When installed in the final position, the stop surface 1.13 on the hook body 1.1 fits against the front wall of the hook mounting hole 2.1, and the positioning surface 1.12 on the hook body 1.1 is in clearance fit with the lower surface of the reinforcing plate 2. This ensures that the upward arching of the top cover 1 cannot exceed the gap height between the positioning surface 1.12 on the hook body 1.1 and the lower surface of the reinforcing plate 2, thus ensuring that the top cover 1 will not have a large upward arching, thereby reducing the gap between the top cover 1 and the drum washing machine body and making the positioning of the top cover 1 more reliable.

[0027] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
