Description

Technical Field

[0001] The invention belongs to the technical field of refrigerators, and in particular relates to a self-locking structure of a refrigerator drawer. Background Art

[0002] Existing refrigerators are generally equipped with drawers. In general, the drawers are placed on rails for use, and the entire drawer is usually in a free state. When the drawer in the refrigerator is used as a vacuum preservation space, since the drawer is in a free state, under normal conditions, the user may not close the drawer properly when placing food or other loads; or because the refrigerator is not placed horizontally, after the drawer is pushed back into place, it slides in the opposite direction and the drawer is not closed properly; the above situations will cause the drawer to fail to vacuum due to the drawer not being closed properly when the drawer is vacuumed. Summary of the invention

[0003] The purpose of the present invention is to provide a self-locking structure for a refrigerator drawer, which solves the existing problems by installing a self-locking mechanism on the refrigerator drawer and locking the drawer after the refrigerator drawer is fully closed.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention is a refrigerator drawer self-locking structure, comprising a drawer body,

[0006] A pull rod handle is provided on the front side of the drawer body; two upper pulleys, two lower pulleys and a self-locking hook are provided on both sides of the drawer body; and limit blocks are provided on the inner walls of the refrigerator opposite to each other on both sides of the drawer body;

[0007] Pull rods are arranged on both sides of the pull rod handle; the pull rod is slidably arranged between the upper pulley and the lower pulley; a limited position rotating shaft is arranged on the pull rod;

[0008] The self-locking hook includes a self-locking hook shaft and a self-locking hook head; the self-locking hook is rotatably arranged on the drawer body through the self-locking hook shaft; two parallel limit rods are arranged on the lock hook shaft; the self-locking hook head cooperates with the limit block; the limit shaft is slidably fitted between the two limit rods.

[0009] Furthermore, a limit stopper is provided at one end of the pull rod; the limit stopper forms a limit fit with the upper row of pulleys.

[0010] Furthermore, the pull rod handle performs linear motion through the cooperation between the pull rod and the upper pulley and the lower pulley; the limit rotating shaft on the pull rod handle drives the self-locking hook to perform circular motion.

[0011] The present invention has the following beneficial effects:

[0012] The present invention installs self-locking structures on both sides of the refrigerator drawer. When the drawer is pulled out by using the pull rod handle, the limit rotating shaft on the pull rod handle drives the self-locking hook to make a circular motion, so that the self-locking hook head and the limit block cooperate with each other, and the drawer is locked after the refrigerator drawer is closed in place to prevent the drawer from sliding.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-2 As shown, the present invention is a refrigerator drawer self-locking structure, comprising a drawer body 1;

[0021] A pull rod handle 2 is provided on the front side of the drawer body 1; two upper pulleys 3, two lower pulleys 31 and self-locking hooks 5 are provided on both sides of the drawer body 1; and limit blocks 6 are provided on the inner walls of the refrigerator opposite to the two sides of the drawer body 1;

[0022] A pull rod 21 is provided on both sides of the pull rod handle 2; the pull rod 21 is slidably arranged between the upper pulley 3 and the lower pulley 31; a limited position rotating shaft 4 is provided on the pull rod 21;

[0023] The self-locking hook 5 includes a self-locking hook shaft 51 and a self-locking hook head 52; the self-locking hook 5 is rotatably arranged on the drawer body 1 through the self-locking hook shaft 51; two parallel limit rods 53 are arranged on the lock hook shaft 51; the self-locking hook head 52 cooperates with the limit block 6; the limit shaft 4 is slidably fitted between the two limit rods 53.

[0024] Among them, a limit stopper 22 is arranged at one end of the pull rod 21; the limit stopper 22 forms a limit fit with the upper pulley 3 to prevent the pull rod 21 from being pulled out.

[0025] The pull rod handle 2 performs linear motion through the cooperation between the pull rod 21 and the upper pulley 3 and the lower pulley 31 ; the limit rotating shaft 4 on the pull rod handle 2 drives the self-locking hook 5 to perform circular motion.

[0026] A specific application of this embodiment is:

[0027] like Figure 1 As shown, when the refrigerator drawer is in the open state, the refrigerator drawer 1 is reset. After the refrigerator drawer 1 is reset, the pull rod handle 2 is pushed to make a linear motion to the right between the upper pulley 3 and the lower pulley 31. The pull rod handle 2 is equipped with a rotating shaft 4, which drives the self-locking hook 5 to make a clockwise circular motion along the self-locking hook rotating shaft 51 on the self-locking hook, and overlaps with the limited blocks 6 arranged on the opposite sides of the drawer to achieve a self-locking effect.

[0028] like Figure 2 As shown, when the refrigerator drawer is opened from a closed state, the pull rod handle 2 is pulled to the left, and moves linearly to the left between the upper pulley 3 and the lower pulley 31. A rotating shaft 4 is installed on the pull rod handle 2, which drives the self-locking hook 5 to move in a counterclockwise circular motion, and after the limit blocks 6 are set opposite to the two sides of the drawer to realize unhooking and unlocking, the refrigerator drawer can be pulled out.
