Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to a screwless door lock. Background Technology

[0002] When installing a washing machine door lock, fasteners are generally used to connect it to the machine, so that the door hook hole on the door lock can be matched with the door hook on the door panel.

[0003] With technological advancements, screwless door locks have emerged, such as the screwless door lock disclosed in Chinese patent document CN214655829U. During insertion, there is no need to manually move the locking slider. The door panel is pressed against the deformable part of the locking slider, causing it to elastically deform. Then, the door panel enters the receiving channel, and the slider spring drives the lock head to exit the receiving groove, ultimately locking the door lock in place.

[0004] However, using the above method requires considerable force from both hands to operate during installation and disassembly, making the operation quite strenuous. Utility Model Content

[0005] In view of this, the present invention provides a screwless door lock to solve the problem of laborious door lock disassembly and assembly.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figure 1 , Figure 2 As shown, this embodiment provides a specific implementation of a screwless door lock, including: a lock housing 1, the lock housing 1 having an outwardly protruding hook hole body 101, the hook hole body 101 having a hook hole formed inside, the hook hole body 101 having a first side and a second side parallel to each other; during installation, the hook hole body 101 is inserted into the door panel hole of the door panel 3, wherein the first side and the second side respectively abut against the two sides of the door panel hole.

[0025] like Figure 3 , Figure 4 As shown, a sliding block 2 is slidably disposed on the lock housing 1, and the sliding direction of the sliding block 2 is perpendicular to the first side; the first side has a notch, and the sliding block 2 has a fitting part 203 for fitting into the notch, and the fitting part 203 has a first locking edge 201 extending in a direction away from the door hook hole, and the sliding block 2 has a locking position in which the fitting part 203 is fitted into the notch and the first locking edge 201 protrudes out of the first side.

[0026] like Figure 5 , Figure 6 As shown, the sliding block 2 also has an unlocking position that separates the fitting part 203 from the notch and makes the first card edge 201 parallel to the first side; like Figure 7 As shown, when the sliding block 2 is in the unlocked position, the door lock moves in a misaligned manner within the door panel hole of the door panel 3, thereby allowing the door lock to be removed from the door panel hole.

[0027] like Figure 1 As shown, the first side has a second locking edge 102 extending in a direction away from the door hook hole. When the sliding block 2 is in the locked position, the door panel 3 is engaged by the cooperation of the first locking edge 201 and the second locking edge 102.

[0028] The screwless door lock provided in this embodiment allows for unlocking and locking operations simply by moving the position of the sliding block 2 during the installation and removal of the lock housing 1. This method eliminates the need for elastic deformation of the sliding block 2, thus reducing the force required for installation and removal and making the door lock easier to assemble and disassemble.

[0029] Specifically, during installation, simply move the door lock relative to the door panel 3 in a staggered manner, and then use the door panel 3 to push the sliding block 2 to the unlock position, thus locking the door lock into the hole in the door panel. During disassembly, push the sliding block 2 from one side of the door hook hole to move it to the unlock position, and then the door lock can be disassembled. like Figure 6 As shown, in some embodiments, it further includes an elastic element connected to the sliding block 2, the elastic element having an elastic force that drives the sliding block 2 to move toward the locked position. By providing the elastic element, the sliding block 2 is held in the locked position, thereby achieving stable installation of the door lock.

[0030] Of course, the above description is not limiting. In some alternative embodiments, the elastic element can be omitted, and other structures can be used to keep the sliding block 2 in the locked position, such as magnetic elements.

[0031] like Figure 6 As shown, in some embodiments, the lock housing 1 has a sliding space 104 for accommodating the sliding block 2, and the elastic element is disposed within the sliding space 104 of the lock housing 1. This arrangement allows the elastic element to be concealed while maintaining its operational stability.

[0032] like Figure 3 As shown, when the sliding block 2 is in the unlocked position, under the action of the elastic element, the sliding block 2 will move away from the door hook hole until it reaches the locked position. At this time, the sliding block 2 abuts against the inner wall of the sliding space 104, thus preventing it from moving further away from the door hook hole. This setting ensures the stability of the elastic element on the lock housing 1 when the door lock is not installed.

[0033] like Figure 6 As shown, in some embodiments, the inner side of the first locking edge 201 has a first guide surface 103, which is inclined in a direction away from the door hook hole. The first guide surface 103 facilitates the insertion of the door hook into the lock hole.

[0034] like Figure 6 As shown, in some embodiments, the inner side of the second locking edge 102 has a second guide surface 204. The second guide surface 204 is inclined in a direction away from the door hook hole, and the inclination angle of the second guide surface 204 is greater than the inclination angle of the first guide surface 103. The second guide surface 204 is provided to facilitate the insertion of the door hook into the lock hole. Setting the inclination angle of the second guide surface 204 to be larger allows the door hook to contact the second guide surface 204 first, thereby ensuring the stability of the sliding block 2.

[0035] like Figure 6 , Figure 8As shown, in some embodiments, the outer side of the first locking edge 201 has a third guide surface 205, which is inclined toward the direction of the door hook hole. The third guide surface 205 is provided to facilitate the insertion of the lock housing 1 into the door panel hole of the door panel 3.

[0036] like Figure 6 , Figure 8 As shown, in some embodiments, the first locking edge 201 is located inside the lock housing 1 relative to the second locking edge 102, and a groove 202 suitable for embedding into the door panel 3 is formed at the root of the first locking edge 201. The groove 202 is provided to allow the door panel 3 to be inserted into the groove 202, thereby improving the stability of the door lock installed on the door panel 3.

[0037] like Figure 4 As shown, in some embodiments, there is one first card edge 201. Of course, the above description is not limiting; in some alternative embodiments, there may be two symmetrical first card edges 201, or multiple first card edges spaced apart.

[0038] Working principle: During installation, first align the door hook hole body 101 of the lock case 1 with the door panel hole of the door panel 3, and insert the first side of the door hook hole body 101 into the door hook hole.

[0039] Then, the door lock is moved in a staggered manner relative to the door panel 3. During this process, the door panel 3 will push the sliding block 2 to the unlock position.

[0040] Then, continue pushing the door lock so that the second side of the door hook hole body 101 is inserted into the door panel hole.

[0041] Finally, move the door lock lever in the opposite direction relative to the door panel 3, causing the sliding block 2 to move toward the locking position. At this point, the door panel 3 is engaged by the cooperation of the first locking edge 201 and the second locking edge 102, completing the door lock installation.

[0042] During the disassembly process, first move the door lock relative to the door panel 3 in a staggered manner. During this process, the door panel 3 will push the sliding block 2 to the unlock position.

[0043] Then, remove the second side of the door lock from the door panel hole.

[0044] Finally, by removing the first side of the door lock from the door panel hole, the door lock can be removed from the door panel hole.

[0045] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
