The present embodiment provides a quick-install door lock, as shown in fig. 1, including: the lock hole comprises a lock hole body 1, wherein the lock hole body 1 is provided with a first side wall 2 and a second side wall 3 which are oppositely arranged, and a door lock is clamped into a mounting hole of a door plate 6 through the first side wall 2 and the second side wall 3. Specifically, the top ends of the first side wall 2 and the second side wall 3 are respectively provided with an extending portion 4 extending outwards, and the extending portions 4 are used for being clamped into the mounting holes of the door panel 6, so that the door lock is clamped and mounted 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. Means that: as shown in fig. 2, the key hole body 1 is mounted toward the end of the door panel 6.

When the lock hole is installed, firstly, the extension part 4 of the first side wall 2 shown in fig. 1 extends into the installation hole of the door panel 6, and the installation hole of the door panel 6 is abutted against the root part of the extension part 4 of the first side wall 2, and at the moment, the other end of the installation hole allows the extension part 4 of the second side wall 3 of the lock hole main body 1 to be inserted; then, extending the extension part 4 of the second side wall 3 into the mounting hole of the door panel 6, and then moving the lock hole main body 1 upwards to make the mounting hole of the door panel 6 be separated from the contact with the first side wall 2, so that the door panel 6 above the mounting hole is inserted into the root part of the extension part 4 of the second side wall 3; finally, the locking piece 5 is inserted into the root of the extension 4 of the first side wall 2, so that the door lock is clamped in the mounting hole of the door panel 6.

As shown in fig. 2, when the door lock is mounted in the mounting hole of the door panel 6, the extension parts 4 of the first and

second side walls

2 and 3 of the lock hole body 1 are respectively supported on the mounting hole, so as to form a snap fit with the lock hole body 1.

As shown in fig. 3, the locking member 5 is rotatably disposed on the first sidewall 2, the locking member 5 has a locking head 7, and when the locking member 5 is rotated, the locking head 7 can be driven to extend into or withdraw from the root of the extension portion 4. In addition, when the mounting hole of the door plate is clamped through the lock head of the locking piece, the lock head only extends into the local area of the root part of the extension part of the first side wall, so that the matching between the lock head and the door plate is reduced, the blocking of the locking piece by the mounting hole is avoided, the lock head of the locking piece can smoothly rotate to the root part of the extension part of the first side wall, and the mounting hole of the door plate is clamped and locked; specifically, as shown in fig. 4, the locking 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 locking head 7; when the locking piece 5 drives the lock head 7 to extend into the root of the extension part 4, the clamping point 8 is matched with the mounting hole of the door plate 6 to clamp the lock hole main body 1. In this embodiment, the locking points 8 on the locking head 7 are cylindrical structures arranged at two ends of the locking head 7, and in addition, as an alternative embodiment, the locking points 8 may be arranged at intervals, and the shapes thereof are not limited to the cylindrical structures, and may also be conventional structures such as spherical protrusions.

As shown in fig. 4, the portion of the locking head 7 between two adjacent locking points 8 is provided with a vacant structure 9, which can reduce the interference between the locking head 7 and the mounting hole of the door panel 6 during the rotation of the locking member 5, and can also reduce the material.

As shown in fig. 4, one end of the locking member 5 away from the locking head 7 is provided with a pressing portion 10 protruding outward, a portion of the pressing portion 10 is an arc-shaped recessed structure 11, and the arc-shaped recessed structure 11 is recessed toward a rotation direction when the locking member 5 is unlocked. Therefore, when the unlocking operation is performed, the unlocking operation can be smoothly performed by pressing the arc-shaped concave structure 11, so that the convenience of the operator in the operation is improved.

As shown in fig. 5, the locking point 8 protrudes from the front and back surfaces (the upper and lower surfaces shown in fig. 5) of the locking head 7 along the thickness direction of the locking head 7, so as to ensure the smooth sliding of the locking head 7 with the locking hole body 1 and the door panel 6.

As shown in fig. 5, the locking member 5 has a rotating shaft 12 protruding inward on a side facing the lock hole body 1, and the rotating shaft 12 has an annular flange 13 protruding in a circumferential direction; the rotating shaft 12 is used for facilitating the rotation of the locking piece 5, and the annular flange 13 on the rotating shaft 12 is used for clamping the locking piece 5 on the lock hole main body 1 so as to prevent the locking piece 5 from falling. In addition, in order to improve the operability, an elastic member such as a torsion spring may be provided on the rotating shaft 12, and the locking head 7 of the locking member 5 may be moved in a direction of being inserted into the root portion of the extending portion 4 of the keyhole body 1 by the elastic force provided by the torsion spring, so that the locking member 5 may be automatically returned and locked when being installed.

As shown in fig. 6, the keyhole main body 1 has a slot hole 15 for accommodating the rotation shaft 12, the slot hole 15 has a limiting cavity 16 for accommodating the annular flange 13 therein, and the width of the limiting cavity 16 is greater than the diameter of the slot hole 15, so that the annular flange 13 on the rotation shaft 12 of the locking member 5 can be clamped by the limiting cavity 16. In addition, the slot hole 15 is formed by assembling two parts, so that the rotating shaft 12 of the locking piece 5 is conveniently clamped in the slot hole 15.

As shown in fig. 5, the locking member 5 has a stopper post 14 protruding inward on the side facing the lock hole body 1; the limiting column 14 is used for extending into the lock hole main body 1 and limiting the rotation path of the locking piece 5 by matching with the lock hole main body 1.

As shown in fig. 6, the lock hole body 1 has a rail groove 17 for accommodating the position-limiting post 14; when the locking member 5 rotates, the position-limiting post 14 moves in the track groove 17, thereby limiting the rotation path of the locking member 5.

In addition, this embodiment still provides a washing machine who adopts above-mentioned lock, and the lock can realize quick assembly disassembly on washing machine's door plant 6 through the joint.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications may be made without departing from the scope of the present invention.
