[0008] The locking member is rotatably arranged on the first side wall, and the locking member has a locking head. When the locking member rotates, the locking head can be driven to extend into or withdraw from the root of the extension portion of the first side wall.

[0009] Optionally, when the locking member rotates, the lock head only cooperates with a local area between the root of the extension portion of the first side wall and the door panel.

[0010] Optionally, the lock head has at least two card points arranged at intervals, and the thickness of the card points is greater than the average thickness of the lock head; when the locking member drives the lock head to extend into the root of the extension portion of the first side wall, the card points are suitable for cooperating with the mounting hole of the door panel to card the lock hole body.

[0011] Optionally, a portion of the lock head between two adjacent locking points is set as a vacant structure.

[0012] Optionally, the clamping points are columnar structures arranged at both ends of the lock head, and the clamping points protrude from the front and back sides of the lock head along the thickness direction of the lock head.

[0013] Optionally, one end of the locking member away from the lock head has a pressing portion protruding outward, and part of the pressing portion is an arc-shaped recessed structure, and the arc-shaped recessed structure is recessed toward the rotation direction of the locking member when unlocking.

[0014] Optionally, the locking piece has a rotating shaft protruding inward on one side of the locking hole body, and the rotating shaft has an annular flange protruding circumferentially; the locking hole body has a slot hole for accommodating the rotating shaft, and the slot hole has a limiting cavity for accommodating the annular flange.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] This embodiment provides a quick-install door lock, such as Figure 1 As shown, it includes: a lock hole body 1, the lock hole body 1 has a first side wall 2 and a second side wall 3 arranged opposite to each other, and the first side wall 2 and the second side wall 3 are used to insert the door lock into the installation hole of the door panel 6. Specifically, the top ends of the first side wall 2 and the second side wall 3 respectively have an extension part 4 extending outward, and the extension part 4 is used to insert into the inside of the installation hole of the door panel 6, so as to install the door lock on the door panel 6. It should be noted that: the top ends of the first side wall 2 and the second side wall 3. Refers to: Figure 2 As shown, the lock hole body 1 faces the end of the door panel 6 when installed.

[0037] When installing, first Figure 1 The extension portion 4 of the first side wall 2 shown is extended into the mounting hole of the door panel 6, and the mounting hole of the door panel 6 is pressed against the root of the extension portion 4 of the first side wall 2. At this time, the other end of the mounting hole allows the extension portion 4 of the second side wall 3 of the lock hole body 1 to be inserted; then the extension portion 4 of the second side wall 3 is extended into the mounting hole of the door panel 6, and then the lock hole body 1 is moved upward to make the mounting hole of the door panel 6 break away from the contact with the first side wall 2, so that the door panel 6 above the mounting hole is inserted into the root of the extension portion 4 of the second side wall 3; finally, the locking piece 5 is inserted into the root of the extension portion 4 of the first side wall 2, so that the door lock is clamped in the mounting hole of the door panel 6.

[0038] like Figure 2 As shown, after the door lock is installed in the installation hole of the door panel 6, the extensions 4 of the first side wall 2 and the second side wall 3 of the lock hole body 1 are respectively supported on the installation hole, thereby forming a snap connection with the lock hole body 1.

[0039] like Figure 3 As shown, the locking member 5 is rotatably arranged on the first side wall 2, and the locking member 5 has a lock head 7. When the locking member 5 rotates, it can drive the lock head 7 to extend into or withdraw from the root of the extension portion 4. In addition, when the mounting hole of the door panel is clamped by the lock head of the locking member, the lock head only extends into a local area at the root of the extension portion of the first side wall, thereby reducing the coordination between the lock head and the door panel, avoiding the blocking of the locking member by the mounting hole, so that the lock head of the locking member can smoothly rotate to the root of the extension portion of the first side wall, and clamp and lock the mounting hole of the door panel; specifically, as shown in FIG. Figure 4 As shown, the lock head 7 of the locking member 5 has two clamping points 8 arranged at intervals, and the thickness of the clamping points 8 is greater than the average thickness of the lock head 7; when the locking member 5 drives the lock head 7 to extend into the root of the extension portion 4, the clamping points 8 cooperate with the mounting hole of the door panel 6 to clamp the lock hole body 1. In this embodiment, the clamping points 8 on the lock head 7 are columnar structures arranged at both ends of the lock head 7. In addition, as an alternative embodiment, the clamping points 8 can also be set to be more spaced, and their shapes are not limited to columnar, and can also be conventional structures such as spherical protrusions.

[0040] like Figure 4 As shown, the portion of the lock head 7 between two adjacent card points 8 is set as a vacant structure 9, which can reduce the interference between the lock head 7 and the mounting hole of the door panel 6 during the rotation of the locking member 5, and can also reduce materials.

[0041] like Figure 4As shown, the end of the locking member 5 away from the lock head 7 has a pressing portion 10 protruding outward, and the pressing portion 10 is a curved recessed structure 11, which is recessed toward the rotation direction of the locking member 5 when unlocking. Therefore, when performing the unlocking operation, the unlocking can be smoothly performed by pressing the curved recessed structure 11, thereby improving the convenience of the operator when performing the operation.

[0042] like Figure 5 As shown, the clamping point 8 protrudes from the front and back sides of the lock head 7 along the thickness direction of the lock head 7 ( Figure 5 The upper and lower surfaces shown in the figure) ensure that the lock head 7 slides smoothly with the lock hole body 1 and the door panel 6 respectively.

[0043] like Figure 5 As shown, the locking member 5 has a rotating shaft 12 protruding inwardly on one side of the lock hole body 1, and the rotating shaft 12 has an annular flange 13 protruding in the circumferential direction; the rotating shaft 12 is used to facilitate the rotation of the locking member 5, and the annular flange 13 on the rotating shaft 12 is used to clamp the locking member 5 on the lock hole body 1 to prevent the locking member 5 from falling. In addition, in order to improve the operability, an elastic member such as a torsion spring can be provided on the rotating shaft 12, and the torsion spring provides an elastic force to move the lock head 7 of the locking member 5 toward the root of the extension part 4 extending into the lock hole body 1, so that the locking member 5 can be automatically reset and locked during installation.

[0044] like Figure 6 As shown, the lock hole body 1 has a slot 15 for accommodating the rotating shaft 12, and the slot 15 has a limiting cavity 16 for accommodating the annular flange 13, and the width of the limiting cavity 16 is greater than the diameter of the slot 15, so that the annular flange 13 on the rotating shaft 12 of the locking member 5 can be clamped through the limiting cavity 16. In addition, the slot 15 is composed of two parts, so that the rotating shaft 12 of the locking member 5 is conveniently clamped in the slot 15.

[0045] like Figure 5 As shown, the side of the locking member 5 facing the lock hole body 1 has a limiting column 14 protruding inwardly; the limiting column 14 is used to extend into the lock hole body 1 and limit the rotation path of the locking member 5 by cooperating with the lock hole body 1.

[0046] like Figure 6 As shown, the lock hole body 1 has a track groove 17 for accommodating the limiting column 14 ; when the locking member 5 rotates, the limiting column 14 moves in the track groove 17 , thereby limiting the rotation path of the locking member 5 .

[0047] In addition, this embodiment also provides a washing machine using the above-mentioned door lock, and the door lock can be quickly disassembled and assembled on the door panel 6 of the washing machine through snap connection.

[0048] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present invention.
