Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of door hooks of a drum washing machine door lock device, and in particular relates to a door hook of a drum washing machine. Background Art
[0002] With the improvement of people's living standards, washing machines have become essential clothing processing equipment for families. Among them, drum washing machines have been widely popular in recent years due to their advantages such as flexible installation space, clean washing, and energy consumption. For drum washing machines with side doors, a metal door hook is usually set on the door body, so that the door hook is locked with the body or unlocked and separated from the body, thereby realizing the opening or closing of the door body. The metal door hook has the disadvantages of high cost and large total equipment weight. In view of this, the present invention is specially proposed. Summary of the invention
[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an integrally formed injection-molded drum washing machine door hook. In order to solve the technical problem, the basic concept of the technical solution adopted by the present invention is: a drum washing machine door hook is composed of a hook part, a root part, and a fixed base. The end of the hook part is pressed with an anti-wear protective sleeve, and the protective sleeve can be stamped from a metal sheet or made of hard plastic. In order to increase the wear resistance and extend the service life of the door hook; the root part is thickened and gradually transitions to the thickness of the hook part to increase the strength, and four pairs of blind grooves are symmetrically arranged to prevent the injection molded parts from shrinking. In addition, the blind groove can also be opened on the fixed base, and the opposite side of the root part can also have the same effect. The edge of the fixed base has a baffle and a screw hole fixed to the drum washing machine door. The utility model has the advantages of low cost and light weight. BRIEF DESCRIPTION OF THE DRAWINGS
[0004] The accompanying drawings are part of the present invention and are used to provide a further understanding of the present invention.

DETAILED DESCRIPTION
[0010] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0011] The first implementation method: Figure 1 , Figure 2 The door hook of a drum washing machine shown in the figure is composed of a hook part, a root part, and a fixed base. The end of the hook part is pressed with an anti-wear protective cover, which can be stamped from a metal sheet or made of hard plastic. This increases the wear resistance and prolongs the service life of the door hook; the root part is thickened and gradually transitions to the thickness of the hook part to increase the strength, and four pairs of first blind grooves are symmetrically arranged to prevent the injection molded parts from shrinking. The fixed base is provided with a baffle and screw holes for fixing.
[0012] The second implementation method: Figure 3 , Figure 4 The door hook of a drum washing machine shown in the figure is composed of a hook part, a root part, and a fixed base. The end of the hook part is pressed with an anti-wear protective cover, which can be stamped from a metal sheet or made of hard plastic. This increases the wear resistance and prolongs the service life of the door hook; the root part is thickened and gradually transitions to the thickness of the hook part to increase the strength, and a second blind groove is opened on the fixed base at the position opposite to the root part to prevent the injection molded part from shrinking, and the fixed base is provided with a baffle and screw holes for fixing.
