TECHNICAL FIELD
[0001] The utility model relates to a kind of laundry washing machine half-concealed door lock pull ring structure, which belongs to laundry washing machine and other laundry processing equipment technical field. BACKGROUND
[0002] Nowadays, laundry processing equipment such as the most common washing machine on the market mostly adopts automatic door lock, i.e., it will be automatically locked during the operation of the washing machine. In order to avoid the washing machine from being unable to normally open the door due to failure or power failure, the user can pull the door lock pull ring in an emergency to manually unlock the washing machine door. Currently, most drum washing machines directly install the door lock pull ring at the drain box, and the user can easily pull the door lock pull ring by hand, which poses a safety hazard and does not meet the requirements of the new national standard.
[0003] Therefore, it is necessary to improve the prior art to solve the problems of the prior art. INVENTION CONTENTS
[0004] The utility model provides a kind of laundry washing machine half-concealed door lock pull ring structure to solve the problems of the prior art, which semi-conceals the door lock pull ring in the drain box. The user can only pull the door lock pull ring with the aid of tools, which improves safety performance.
[0005] The utility model adopts the following technical scheme: a kind of laundry washing machine half-concealed door lock pull ring structure is installed in the drain box. The drain box includes a mounting portion for mounting the door lock pull ring. The mounting portion includes a first support portion adjacent to the surface of one side of the door lock pull ring and a second support portion adjacent to the surface of the other side of the door lock pull ring. The first support portion and the second support portion are spaced apart. The door lock pull ring is installed in the mounting portion and located between the first support portion and the second support portion. An automatic door lock is externally connected to the door lock pull ring. A notch portion is formed at the end of the second support portion away from the automatic door lock.
[0006] Further, the second support portion includes two spaced-apart portions.
[0007] Further, a first protrusion is formed on the surface of the first support portion facing the door lock pull ring.
[0008] Further, a second protrusion is formed on the surface of each of the two second support portions facing the door lock pull ring.
[0009] Further, the notch portion is formed on the second support portion away from the automatic door lock, and the notch portion is located on one side of the second protrusion.
[0010] Further, after the door lock pull ring is installed in the mounting portion, the end thereof away from the automatic door lock extends to the position of the notch portion.
[0011] The utility model has the advantages of the following: the utility model discloses a door lock pull ring half-concealed in the drainage box, so that the user can only pull the door lock pull ring with the aid of a tool, and the door lock pull ring cannot be pulled manually without the tool, thereby improving the safety performance of the washing machine.
