Description

Refrigerator with a refrigerator body Technical Field The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background The refrigerator is provided with a box body and a door body, and the box body and the door body are tightly closed by arranging a connecting structure such as a magnet, for example, the door body is provided with the magnet, and the magnet is adsorbed to the box body through the magnetic force of the magnet, so that the door body is kept in contact with the box body, and the door body is kept to be closed. However, the connecting structure simultaneously causes the door opening to be unchanged, and the related art adopts a power assisting mechanism to extend the ejector rod to prop against the box body, so that the power assisting door opening is realized. The power assisting mechanism can be arranged at the bottom of the door body or at the side surface of the door body. The helping hand mechanism sets up the benefit in the bottom of the door body, can not show in the surface of refrigerator, realizes hidden design, and the outward appearance uniformity is better. However, the door body has a small bottom operation space, and limits the structure of the booster mechanism, for example, the handle has no space to rotate downward, so that the door body is generally configured to extend outwards. In the related art, there is a refrigerator that can open and close a door body at either side (i.e., right-hand side and left-hand side). In this refrigerator structure, two cam mechanisms for engaging and disengaging the refrigerator body and the door body with and from each other are installed at both left and right sides of the door. Referring to fig. 19, if the booster mechanism is provided at the bottom of the door body of the above-mentioned refrigerator, the door body is rotated around the right side to open the left side position, and the left side position is required to be provided with the cam mechanism, and therefore, the booster mechanism is required to be provided at an offset position. In addition, in order to make the power-assisted mechanism more labor-saving, the ejector rod should be arranged at a position close to the left side, so that the distance between the ejector rod and the right side rotating shaft is increased. Accordingly, the handle is located at one side of the top rod facing the center line of the door body, and when the door is opened, the handle rotates from right to left, i.e. counterclockwise in the drawing, and when the door body at the left side is opened, the door body needs to be rotated left to right, i.e. clockwise in the drawing. The two rotation directions are different, so that a user needs to change the force direction when opening the door, and the use is inconvenient. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the refrigerator provided by the invention can realize hidden design and can also improve the convenience of use. The refrigerator comprises a refrigerator body, a door body, 4 hinges and an assisting mechanism, wherein the 4 corners of the door body are respectively connected to the refrigerator body through 1 hinge, the hinge allows any one of the left side and the right side of the door body to be meshed with and separated from the refrigerator body, the hinge comprises a fixed piece, a first rotating shaft and a movable piece, the fixed piece and the first rotating shaft are connected to the refrigerator body, the movable piece is connected to the door body, the movable piece is provided with a sliding groove, the fixed piece is provided with a through hole, the first rotating shaft penetrates through the through hole and can slide along the sliding groove, the opening of the sliding groove faces the refrigerator body, the sliding groove comprises a first sliding section and a second sliding section, the opening of the sliding groove is positioned on the first sliding section, when the door body is closed, the first rotating shaft on both sides is kept at the first rotating shaft and the second rotating shaft, the sliding section is positioned on the other side, and the sliding groove is in front of the sliding section, and the sliding groove is positioned on the other side, and the sliding groove is used for limiting the rolling wheel assembly to move along the first inclined surface, and the rolling wheel assembly is arranged on the other side, and the sliding section is opened; the power assisting mechanism is positioned at the bottom of the door body and comprises a handle, the door comprises a door body, a handle, a driving mechanism and a push rod, wherein the push rod is arranged on the door body in a sliding mode, the driving mechanism is used for amplifying power transmitted by the handle and continuously transmitting the power to the push rod, the roller assembly is located at the rear si
