Of course, the stop arm 71 and the stop seat 72 may be disposed at other positions of the door body 100, and the purpose of stopping and limiting is within the scope of the present invention.

Further, the stop seat 72 is arranged on the side frame 2 of the upper door body 101 and extends downwards, the stop arm 71 is arranged on the side frame 2 of the lower door body 102 and extends towards the upper door body, because the end of the stop arm 71 exceeds the side frame of the lower door body 102, when the stop arm 71 is limited by the stop seat 72, a distance exists between the side frame 2 of the lower door body 101 and the stop seat 72, that is, the length of the stop arm 71, and correspondingly, the distance between the handle arranged on the side frame 2 of the lower door body 102 far away from the stop arm 71 and the frame of the upper door body 102 also increases the length of the stop arm, so that a sufficient safety space is provided for the periphery of the handle.

Specifically, the stopping seat 72 has a stopping surface matched with the stopping arm 71, and an included angle between the stopping surface and the plane where the side frame 2 is located is greater than 90 °, so that the stopping seat 72 not only limits the lower door body 101 in the sliding direction, but also limits the lower door body in the up-down direction due to the inclined arrangement of the stopping surface, so as to ensure the sliding safety of the lower door body 102. Preferably, said stop surface is perpendicular to the lower surface of said side frame 2.

In this embodiment, the stop seat 72 includes a pair of side plates extending from two ends of the stop surface in a direction away from the door panel, so that the stop surface and the side plates form a right triangle shape and are fixed on the side frame 4 to improve the stability of the stop seat 72.

Further, one side of the stop arm 71 facing away from the side frame 2 has an abutting surface, and when the lower door body 101 and the upper door body 102 are in an overlapped state, the abutting surface abuts against the stop surface to limit the continuous sliding of the lower door body 102.

Further, the stop arm 71 has a fixing surface fixed to the side frame 2, the area of the fixing surface is larger than that of the abutting surface, and as the fixing surface for connecting and fixing the stop arm to the side frame 2, the larger area can increase the contact between the stop arm 71 and the side frame 2, so that the stability of the stop arm 71 is improved in the process of stopping and limiting the lower door body 102.

It can be understood that, the stopping mechanism 7 may be provided in a group or in multiple groups at intervals between the upper door body 101 and the lower door body 102, which is within the protection scope of the present invention.

To sum up, the utility model discloses a refrigeration plant is through last door body 101 and be equipped with sealed muscle 21 and sealing strip 822 down between the door body 102 for door body 100 is when the open mode, and the leakproofness is better, can not lead to revealing of refrigeration plant air conditioning, reduces refrigeration plant's loss, reaches energy saving and emission reduction's purpose.

It should be understood that although the specification describes embodiments, not every embodiment includes only a single embodiment, and such description is for clarity purposes only, and it will be understood by those skilled in the art that the specification as a whole and the embodiments may be combined as appropriate to form other embodiments as would be understood by those skilled in the art.

The above detailed description of a series of embodiments is only for the purpose of illustration, and is not intended to limit the scope of the invention, which is intended to include all equivalent embodiments or modifications that do not depart from the spirit of the invention.
