Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator turnover beams, in particular to a turnover beam with a self-locking function. Background Art
[0002] Most refrigerator flip beams today do not have a self-locking function. When closing the door, the flip beam and the refrigerator door body change from a vertical state to a parallel state. When opening the door, the flip beam and the refrigerator door body change from a parallel state to a vertical state. However, the flip beam does not have a self-locking function. During and after the refrigerator door is opened, the flip beam may be parallel to the refrigerator door body due to accidental contact. When closing the door, the flip beam and the refrigerator door body are parallel, and the flip beam will interfere with the closing of the door body. Closing the door with too much force may cause damage to the flip beam. Utility Model Content

DETAILED DESCRIPTION
[0025] The utility model is further described below in conjunction with the accompanying drawings.
[0026] The orientations mentioned in this specification are based on the orientations of the flip beam with a self-locking function of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative position relationships, not absolute position relationships.
[0027] like Figures 1 to 6As shown, a flip beam with a self-locking function includes a flip beam body 1, an upper rotating seat 2 and a limiting column 3. The flip beam body 1 includes a rear cover 10, a front cover 11, a cover plate 12, a heating wire 13 and a self-locking component 4. The self-locking component 4 is installed in the area where the rear cover 10 and the front cover 11 are buckled, the limiting column 3 is arranged at the upper end of the rear cover 10, the heating wire 13 is arranged in the area where the cover plate 12 and the front cover 11 are buckled, and the upper rotating seat 2 is installed on the refrigerator door body 14. The self-locking component 4 includes a self-locking support 5, a slider 6, a reset block 7 and a push rod 8.
[0028] The flip beam body 1 is provided with a self-locking support 5, and the self-locking support 5 is provided with a slider 6 that can move left and right, a reset block 7 that can move up and down, and a push rod 8 that can move up and down; the lower end of the reset block 7 is provided with a self-locking protrusion 70, and the upper end of the upper rotating seat 2 is provided with a self-locking groove 20 that matches the self-locking protrusion 70. Preferably, the self-locking groove 20 is arranged in an arc shape, and there are four self-locking grooves 20 evenly distributed along the circumference and the four self-locking grooves 20 are connected end to end, and there are two self-locking protrusions 70 evenly distributed along the circumference. When the slider 6 is not clamped into the upper end of the reset block 7, when the flip beam rotates, the reset block 7 can move upward, so that the self-locking protrusion 70 leaves the self-locking groove 20. After the slider 6 is clamped into the upper end of the reset block 7, the reset block 7 cannot move upward, the self-locking protrusion 70 is clamped in the self-locking groove 20, and the flip beam cannot rotate.
[0029] The upper end of the push rod 8 abuts against the lower end of the limiting column 3, and preferably the upper end of the push rod 8 is connected to the lower end of the limiting column 3. The self-locking support 5 is provided with a first elastic mechanism for driving the push rod 8 to move upward. When the push rod 8 moves upward, it drives the slider 6 to move against the upper end of the reset block 7, so that the self-locking protrusion 70 and the self-locking groove 20 are engaged.
[0030] As a conventional structure of the flip beam, the limit post 3 extends out of the upper end of the flip beam body 1 and can move up and down.

A limit seat 16 is provided on the refrigerator body 15, and a limit groove 17 is provided on the limit seat 16. When the refrigerator door 14 is closed, the limit post 3 moves along the limit groove 17, so that the flip beam rotates from a state perpendicular to the door body to a state parallel to the door body. When the refrigerator door 14 is closed, the portion where the limit post 3 first enters the limit groove 17 is provided with an inclined guide slope 30. When the refrigerator door 14 is closed, the limit post 3 gradually moves downward under the action of the guide slope 30 and the limit groove 17.
[0031] When the door is closed, the limit column 3 is pressed down by the limit groove 17, and the push rod 8 is at the bottom. The push rod 8 drives the sliding block 6 to be located at the rightmost side of the self-locking support 5. At this time, there is no interference of the sliding block 6 on the reset block 7, and the flip beam can rotate freely; when the limit column 3 is about to leave the limit groove 17 during the door opening process, the first elastic mechanism drives the push rod 8 to move upward, and the push rod 8 drives the sliding block 6 to move to the left, and the sliding block 6 rests on the upper end of the reset block 7. There is no movable space between the upper rotating seat 2 and the reset block 7, the self-locking protrusion 70 and the self-locking groove 20 are engaged, and the flip beam cannot rotate.
[0032] The utility model can realize that the flip beam is self-locked in a vertical state with the refrigerator door body 14 when the door is opened, and will not interfere with the closing of the door body and damage the flip beam. The self-locking component 4 in the utility model is an independent module, which can be installed on the flip beam body 1 as needed, and the installation is simple.
