As shown in fig. 1 to 6, the present embodiment provides a refrigerator door lock, including:

the plug block 1 is provided with at least two plug parts 11;

a pair of refrigerator cover plates 2 for being assembled on a refrigerator door 3 or a refrigerator body 4 of a refrigerator; each refrigerator cover plate 2 is provided with at least one insertion hole 21, and the insertion part 11 is in insertion fit with the insertion holes 21 on the pair of refrigerator cover plates 2 so as to lock the refrigerator door 3.

Therefore, the refrigerator door lock is different from the structure for locking the refrigerator door 3 in the prior art, is only formed by the mutually matched insertion block 1 and the pair of refrigerator cover plates 2, and is simple in structure and very convenient to use. The refrigerator cover 2 is a separate component that can be mounted on the door 3 or the cabinet 4 of the refrigerator, which is the use state. In addition, the single component can be detached relative to the refrigerator door 3 or the refrigerator body 4 of the refrigerator, and does not influence the basic structure of the refrigerator, namely, the refrigerator is in an unused state.

Because the use and the nonuse of the refrigerator door lock can not influence the basic structure of the refrigerator, the refrigerator door lock can be adapted to various types of refrigerators, such as a single-door refrigerator, a double-door refrigerator or a multi-door refrigerator, the refrigerator door lock can install the pair of refrigerator cover plates 2 on the matching positions of the refrigerator according to requirements when in use, and then the refrigerator is switched into a locking state or an unlocking state by utilizing the matching between the insert block 1 and the pair of refrigerator cover plates 2.

Referring to fig. 17 in combination, for example, when the refrigerator door lock is assembled in a single-door refrigerator, a pair of the refrigerator cover plates 2 may be respectively assembled on the refrigerator body 4 and the refrigerator door 3, and when the insertion portion 11 of the insertion block 1 is simultaneously inserted into the insertion hole 21 of the pair of refrigerator cover plates 2, the insertion block 1 may lock the pair of refrigerator cover plates 2, and thus indirectly lock the refrigerator door 3 on the refrigerator body 4, which is a locked state of the refrigerator.

When the locked state of the refrigerator needs to be switched to the unlocked state, the insert block 1 can be separated relative to the pair of refrigerator cover plates 2, and the inserted state between the insert block 1 and the pair of refrigerator cover plates 2 is released, so that the refrigerator body 4 and the refrigerator door 3 of the refrigerator cannot be locked by the refrigerator door lock, namely the unlocked state of the refrigerator.

Similarly, when the refrigerator door lock is assembled on a double-door refrigerator, the pair of refrigerator cover plates 2 can be respectively assembled on the pair of refrigerator doors 3, and the inserting portion 11 of the inserting block 1 is simultaneously inserted into the inserting hole 21 of the pair of refrigerator cover plates 2, at this time, the inserting block 1 can lock the pair of refrigerator cover plates 2, so as to indirectly lock the pair of refrigerator doors 3, which is a locking state of the refrigerator.

When the locked state of the refrigerator needs to be switched to the unlocked state, the insert block 1 can be separated relative to the pair of refrigerator cover plates 2, and the inserted state between the insert block 1 and the pair of refrigerator cover plates 2 is released, so that the pair of refrigerator doors 3 of the refrigerator cannot be locked by the refrigerator door lock, namely the unlocked state of the refrigerator.

In addition, the refrigerator door lock can be matched with a multi-door refrigerator, at the moment, a single refrigerator door lock or a plurality of refrigerator door locks can be assembled with the multi-door refrigerator according to the use principle of the refrigerator door lock in the single-door refrigerator or the double-door refrigerator, and any refrigerator door 3 of the multi-door refrigerator can be switched to be in a locking state or an unlocking state independently or simultaneously, so that the multi-door refrigerator can be locked or unlocked.

Referring to fig. 18 in combination, for example, a plurality of refrigerator door locks may be configured on a multi-door refrigerator for simultaneous use, for example, in the structure of the refrigerator door lock and a single-door refrigerator, a refrigerator door lock may be disposed between each of the refrigerator doors 3 and the refrigerator body 4, so that a single refrigerator door lock is matched with the refrigerator door 3 of a single refrigerator and the refrigerator body 4 of the refrigerator, and the refrigerator door 3 corresponding to the refrigerator is independently or individually switched to a locked state or an unlocked state, and the use principle at this time is the same as that of the refrigerator door lock used on the single-door refrigerator, which is not described herein again.

Or, like the structure of the refrigerator door lock and the double-door refrigerator, the size of the insert block 1 in the refrigerator door lock can be increased, at the moment, each refrigerator door 3 can be provided with the refrigerator cover plate 2, and the insert block 1 can cover a plurality of refrigerator cover plates 2 of a plurality of refrigerator doors 3 after the size is increased, so that the insert block and the refrigerator cover plates 2 form an inserted locking state and an unlocking state simultaneously. Therefore, the refrigerator door lock after being increased in size can lock a plurality of doors 3 of a multi-door refrigerator simultaneously through the single insert block 1, and the operation efficiency is improved. The technical personnel in the field can set according to the needs, and do not limit here.

It should be noted that, because the refrigerator door lock mainly prevents children from opening the refrigerator without permission, when the refrigerator cover plate 2 is assembled, no matter the refrigerator is a single-door refrigerator or a double-door refrigerator, the refrigerator cover plate 2 needs to be installed above the middle part of the refrigerator door 3 and has enough height to prevent children from touching, so as to prohibit children from opening the refrigerator without permission.

For example, the refrigerator cover plate 2 can be installed on the top end face of the refrigerator door 3, so that the refrigerator door can be operated by adults conveniently, and after the insertion block 1 is inserted and assembled on the refrigerator cover plate 2, the insertion block 1 can be stably positioned in the insertion hole 21 of the refrigerator cover plate 2 under the action of gravity, and the stability of the locking state is improved. In addition, the refrigerator cover plate 2 can be arranged on the side wall of the refrigerator door 3, and for a refrigerator with a higher overall height, a part of adults can not easily touch the top of the refrigerator, so that the refrigerator cover plate is arranged on the side wall of the refrigerator, and the operation of a user can be facilitated. At the moment, the inserting part 11 of the inserting block 1 is inserted into the inserting hole 21 of the refrigerator cover plate 2, the locking effect between the inserting part 11 and the inserting hole 21 is also enhanced under the action of gravity, and the stability of the locking state is further ensured.

In addition, for refrigerators of different models and specifications, the overall heights of the refrigerators may be different, so that for the refrigerators of different models and specifications, the installation height of the refrigerator door lock can be set in a targeted manner, and the refrigerator door lock is guaranteed to be higher than that of a common child. At this time, since the refrigerator door lock is a detachable or assembled part independent of the refrigerator, the refrigerator door lock does not occur to be unsuitable even for refrigerators of different models and specifications.

Of course, if the user uses other applications, the refrigerator cover plate 2 may be disposed at other positions of the refrigerator, and the refrigerator door lock may not only be suitable for preventing children from opening the refrigerator door, but also be used to improve the locking effect of the refrigerator door 3, for example, to prevent the refrigerator sealing layer from aging and the sealing from being untight, and therefore, a person skilled in the art may perform corresponding setting on the refrigerator door lock according to the actual use condition of the refrigerator, and the setting is not limited herein.

With continued reference to fig. 7 and 8, the inserting portion 11 is an inserting column, and the inserting hole 21 is a cylindrical groove. The inserting part 11 of the inserting column and the inserting hole 21 of the cylindrical groove can form a matched inserting structure, and when the refrigerator needs to be locked, the inserting part 11 of the inserting column can be inserted into the inserting hole 21 of the cylindrical groove. At the moment, the inserting process of the inserting block 1 is close to or far away from the pair of refrigerator cover plates 2, so the refrigerator cover plates 2 can be arranged at the top of the refrigerator, and therefore, a user only needs to take up or drop the inserting block 1 to insert, and the operation is very convenient. In addition, at least one refrigerator cover plate 2 is further provided with a placing hole 24, the inserting part 11 is matched with the placing hole 24 and the inserting hole 21 on the same refrigerator cover plate 2, and the inserting part 11 is matched with the placing hole 24 and the inserting hole 21 on the same refrigerator cover plate 2 in an inserting mode.

Therefore, the insert block 1 and the pair of refrigerator cover plates 2 can be assembled in two inserting and connecting states, the first state is that the inserting part 11 of the insert block 1 is inserted into the inserting hole 21 of the pair of refrigerator cover plates 2 simultaneously, so that the pair of refrigerator cover plates 2 are locked, and the refrigerator door 3 is locked at the moment. The second type is that the insertion part 11 of the insertion block 1 is simultaneously inserted with the insertion hole 21 and the placing hole 24 on the single refrigerator cover plate 2, and at the moment, the insertion block 1 is only inserted with the single refrigerator cover plate 2, so that the pair of refrigerator cover plates 2 cannot be locked, the unlocking state of the refrigerator is achieved, the insertion block 1 is inserted on the single refrigerator cover plate 2 and can be conveniently placed, and the refrigerator is convenient to use again.

The plugging column of the plugging portion 11 may be a prism, a cylinder, or the like, and in cooperation with this, the cylindrical groove of the plugging hole 21 may be a prism, a cylinder, or the like. When the inserting part 11 and the inserting hole 21 are the prism body and the prism groove which are matched with each other, the prism body is inserted into the prism groove, so that the inserting connection effect can be formed, the circumferential limiting effect can be formed, the inserting block 1 is prevented from rotating, and the locking stability is improved.

With continued reference to fig. 9 to 11, the insertion column is a cylinder, and the cylindrical groove is a cylindrical groove; the side wall of at least one cylinder is provided with a rotation stopping bulge 22, the inner wall of the cylindrical groove is provided with a rotation stopping groove 23, and the rotation stopping bulge 22 is in inserted fit with the rotation stopping groove 23.

At this time, although the insertion part 11 and the insertion hole 21 are a cylinder and a cylindrical groove which are mutually matched, the side wall of the cylinder and the inner wall of the cylindrical groove are respectively provided with a rotation stopping protrusion 22 and a rotation stopping groove 23 which are matched, when the rotation stopping protrusion 22 is in insertion fit with the rotation stopping groove 23, a circumferential limiting effect can be formed, the insertion block 1 is prevented from rotating, and the locking stability is improved.
