DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example: See Figures 1 to 9 According to an embodiment of the utility model, a technical solution is provided: a safety lock for a commercial refrigerator, comprising a cabinet 1, a storage cavity 2 is defined inside the cabinet, an opening communicating with the storage cavity 2 is provided on the cabinet 1, and the opening is slidably covered by a cabinet door 3; an L-shaped locking portion 4 is fixed to the bottom of the cabinet door 3, a locking mechanism 5 is provided in the storage cavity 2, the locking mechanism 5 selectively fixes the locking portion 4 and the cabinet 1 relative to each other to limit or allow the locking portion 4 to move relative to the cabinet 1; and an unlocking mechanism 6, an unlocking groove 7 is provided on the peripheral side wall of the cabinet 1, the unlocking groove 7 is selectively covered by a cover 8, the unlocking mechanism 6 is provided in the unlocking groove 7, and the unlocking mechanism 6 is used to release the relative fixed state of the locking portion 4 and the cabinet 1.

[0030] The safety lock for commercial refrigerators using the above structure is used. When the user needs to open the cabinet door 3, he first opens the cover 8 on the cabinet body 1 to expose the unlocking mechanism 6. Then, the user uses the unlocking mechanism 6 to release the relative fixed state between the locking portion 4 and the cabinet body 1, so that the user can open the cabinet body 1. After the user has taken out the items in the storage cavity 2, the user slides the cabinet door 3 to cover the opening of the cabinet body 1. At this time, the locking mechanism 5 will fix the locking portion 4 and the cabinet body 1 in a relative fixed state to facilitate the fixation of the cabinet body 1. When the user does not need to open the cabinet body 1, the user uses the cover 8 to cover the unlocking slot 7 to shield the unlocking slot 7 and prevent the unlocking mechanism 6 from being discovered by children.

[0031] In this embodiment, the locking mechanism 5 includes a locking plate 9, a locking hook 10 and a torsion spring 11. The locking plate 9 is arranged in the storage cavity 2. A placement groove 13 is provided on the locking plate 9 along its length direction. The handle of the locking hook 10 is rotatably arranged in the placement groove 13 through a shaft column 14. A locking groove 15 is provided on the locking plate 9. The torsion spring 11 is arranged on the shaft column 14 to elastically abut the hook of the locking hook 10 into the locking groove 15. The locking groove 15 is suitable for the locking portion 4 to be inserted; the user can adjust the locking mechanism 5 in accordance with the embodiment of the present invention. When the cabinet body 1 and the cabinet door 3 are to be fixed relative to each other, the cabinet door 3 is directly slid to cover the opening on the cabinet body 1. At this time, the locking portion 4 will push the hook portion of the locking hook 10 outward to disengage the hook portion of the locking hook 10 from the locking groove 15, so as to facilitate the locking portion 4 to be inserted into the locking groove 15. When the locking portion 4 is completely inserted into the locking groove 15, the locking hook 10 will be elastically pressed into the locking groove 15 by the torsion spring 11 to limit the locking portion 4 from disengaging from the locking groove 15, and at the same time limit the movement of the cabinet door 3 relative to the cabinet body 1.

[0032] In this embodiment, the unlocking mechanism 6 includes an unlocking button 16, which is arranged in the unlocking groove 7. The shaft column 14 movably passes through the cabinet 1 and extends into the unlocking groove 7, and the unlocking button 16 is fixed to the shaft column 14; when the user needs to disengage the hook portion of the locking hook 10 from the locking groove 15, the user first opens the cover body 8 to expose the unlocking button 16, and then twists the unlocking button 16 to drive the shaft column 14 to rotate, thereby driving the locking hook 10 to rotate so that the hook portion of the locking hook 10 disengages from the locking groove 15, thereby facilitating the locking portion 4 to disengage from the locking groove 15.

[0033] In this embodiment, a guide rod 17 is fixed to the first end of the cover body 8, a guide hole 18 is provided in the cabinet body 1, a spring 12 is provided in the guide hole 18, the guide rod 17 is provided in the guide hole 18, and is elastically abutted by the spring 12; after the user moves the cover body 8 to expose the unlocking slot 7, the spring 12 will elastically abut the guide rod 17, so that the cover body 8 will automatically cover the unlocking slot 7 after the user uses the unlocking mechanism 6.

[0034] In this embodiment, a pull shaft 19 is disposed inside the cover body 8 ; when the user opens the cover body 8 , the pull shaft 19 provides the user with a fulcrum for opening the cover body 8 , so that the user can open the cover body 8 easily.

[0035] In this embodiment, a plurality of friction-increasing grooves 20 are spaced apart along the circumference of the unlocking button 16 ; when the user needs to twist the unlocking button 16 , the friction-increasing grooves 20 increase the friction between the user's fingers and the unlocking button 16 , making it easier for the user to twist the unlocking button 16 .

[0036] Working principle: when the user needs to open the cabinet door 3, he first opens the cover body 8 on the cabinet body 1 to expose the unlocking mechanism 6, and then opens the cover body 8 to expose the unlocking button 16, and then twists the unlocking button 16 to drive the shaft column 14 to rotate, so as to drive the locking hook 10 to rotate so that the hook portion of the locking hook 10 is disengaged from the locking groove 15, so that the locking portion 4 is disengaged from the locking groove 15, so that the user can open the cabinet body 1. After the user has taken out the items in the storage cavity 2, the user directly slides the cabinet door 3 to cover the opening on the cabinet body 1. At this time, the locking portion 4 will push the hook portion of the locking hook 10 outward to disengage the hook portion of the locking hook 10 from the locking groove 15, so that the locking portion 4 can be inserted into the locking groove 15. When the locking portion 4 is completely inserted into the locking groove 15, the locking hook 10 will be torsion spring 11 elastically abuts against the locking groove 15 to limit the locking portion 4 from disengaging from the locking groove 15, and at the same time limits the movement of the cabinet door 3 relative to the cabinet body 1. When the user does not need to open the cabinet body 1, the user uses the cover body 8 to cover the unlocking groove 7 to shield the unlocking groove 7 and prevent the unlocking mechanism 6 from being discovered by children; after the user moves the cover body 8 to expose the unlocking groove 7, the spring 12 elastically abuts against the guide rod 17, so that the cover body 8 automatically covers the unlocking groove 7 after the user uses the unlocking mechanism 6; when the user opens the cover body 8, the pull shaft 19 gives the user a fulcrum for opening the cover body 8, so that the user can open the cover body 8; when the user needs to twist the unlocking button 16, the friction increasing groove 20 increases the friction between the user's finger and the unlocking button 16, so that the user can twist the unlocking button 16.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
