In this way, when the user does not drive the limiting member 42 to open the second door 20 through the rotation shaft 30, that is, manually open the second door 20, the air outlet shaft 60 can also be enabled to outlet air to form an air curtain on the front side of the accommodating cavity 101, so as to reduce the leakage amount of cold air in the accommodating cavity 101 when the second door 20 is opened.

Specifically, the connecting piece 41 may be a gear or a clamping block, and the connection position between the limiting piece 42 and the connecting piece 41 may also be adaptively changed according to the structural form of the connecting piece 41, which can be understood that the specific structural forms of the connecting piece 41 and the connecting end between the limiting piece 42 and the connecting piece 41 are not unique.

It will be appreciated that the specific configuration of the clutch mechanism 40 is not exclusive and that any specific configuration that allows for a controlled connection or disconnection of the clutch mechanism 40 to the rotatable shaft 30 is one of the alternative embodiments of the present application.

Optionally, the limiting piece 42 is provided with a shifting portion 421, and the shifting portion 421 is extended along the direction of the first door body 10 toward the second door body 20; wherein, the second door body 20 is provided with an opening, the opening is arranged corresponding to the shift portion 421, and a portion of the shift portion 421 passes through the opening to be exposed to the second door body 20, so that the limiting member 42 moves between the first position and the second position through the movable shift portion 421.

By adopting the embodiment of the disclosure, the gear shifting portion 421 is arranged on the limiting piece 42, the gear shifting portion 421 can be exposed out of the second door body 20 through the opening on the second door body 20, and a user can manually control the position of the gear shifting portion 421 and then control the position of the limiting piece 42, so that the user can freely select the second door body 20 to be opened according to the use requirement of the user.

Wherein, the stopper 44 has an initial position and a compressed position and is movable between the initial position and the compressed position, when the stopper 44 is at the initial position, the stopper 44 abuts against the shift portion 421 to define the position of the shift portion 421; when the stopper 44 is in the compressed position, the shift portion 421 can move relative to the stopper 44.

By adopting the embodiment of the disclosure, by arranging the fixing seat 43 and the limiting block 44, the limiting block 44 can be abutted with the shifting part 421 to fix the position of the shifting part 421, so as to fix the position of the limiting piece 42, and the limiting piece 42 is stably located at the first position or the second position. The shift portion 421 can move relative to the stopper 44, that is, the shift portion 421 is not in contact with the stopper 44, the stopper 44 cannot define the position of the shift portion 421, and the shift portion 421 can freely fall under the action of gravity or move upward under the action of external force.

For example, as shown in fig. 6, the stopper 44 may move in the up-down direction relative to the connector 41, and since the shift portion 421 is provided at the stopper 44, the first position and the second position of the shift portion 421 are the uppermost and the lowermost positions where the shift portion 421 can move, respectively, wherein the position where the shift portion 421 is at the uppermost end is defined as the first position, and the position where the shift portion 421 is at the lowermost end is defined as the second position.

When the stopper 44 is located at the compression position, the stopper 44 is not in contact with the shift portion 421, the stopper 44 cannot define the position of the shift portion 421, and the shift portion 421 can freely fall to the second position under the action of external force or move upward to the first position under the action of external force.

When the limiting member 42 is not subjected to an external force or the external force is insufficient to elastically deform the elastic member 45, the limiting member 42 is at the initial position. In this way, the limiting block 44 can automatically rebound to the initial position, so that the situation that the limiting block 42 falls back to the second position under the action of gravity due to the fact that the limiting block 44 cannot timely move to the initial position when the limiting block 42 moves from the second position to the first position is avoided. The situation that the limiting piece 42 moves from the first position to the second position when the shifting portion 421 is touched by mistake can be avoided, and then the limiting effect of the limiting piece 42 by the limiting piece 44 can be guaranteed.

Specifically, the elastic member 45 may be a spring or a rubber member, and it is understood that the specific form of the elastic member 45 is not unique.

Thus, the position control structure is not required to be arranged on the limiting piece 42 alone, and the size of the acting force applied to the shifting part 421 is changed, so that when the acting force transmitted to the limiting piece 44 by the shifting part 421 is larger than the threshold value of elastic deformation of the elastic piece 45, the limiting piece 44 can be moved from the initial position to the compression position, and the user can conveniently adjust the position of the shifting part 421 and simultaneously reduce the structural complexity and cost of a door body assembly of the refrigeration equipment.

Specifically, as shown in fig. 6, the shift portion 421 is provided obliquely toward both ends of the end of the stopper 44, and both ends of the end surface of the stopper 44 toward the shift portion 421 are provided as inclined surfaces that are adapted to the inclined surfaces of the shift portion 421. In this way, when the stopper 42 is in the first position, the guide structure 441 of the stopper 44 abuts against the guide portion 4211 of the shift portion 421, the stopper 44 can provide sufficient supporting force to the shift portion 421, and by being provided in the form of a slope, the movement resistance of the shift portion 421 can be effectively reduced.

For example, as shown in fig. 6, the upper and lower ends of the limiting block 44 are both provided with guiding structures 441 toward the end of the shift portion 421, and similarly, the upper and lower ends of the shift portion 421 are also provided with guiding portions 4211 adapted to the guiding structures 441.

In this way, the stopper 44 can be facilitated to define the position of the shift portion 421, and the shift portion 421 can be facilitated to move relative to the stopper 44.

It should be noted that the guide structure 441 and the guide portion 4211 may also be configured in an arc shape, and specific structural forms of the guide structure 441 and the guide portion 4211 include, but are not limited to, those shown in the drawings.
