In the various illustrations of the invention, some dimensions of structures or portions may be exaggerated relative to other structural portions for convenience of illustration, and thus serve only to illustrate the basic structure of the inventive subject matter.

The invention provides refrigeration equipment, as shown in fig. 1 to 16, which comprises a box body 200 defining a storage space, a cabinet opening 201 at an opening of the box body 200, and a door body 100 covering the cabinet opening 201, wherein the door body 100 comprises an upper door body 101 and a lower door body 102 which are arranged up and down, the cabinet opening 201 is provided with a guide step 202 for supporting the upper door body 101 and the lower door body 102 respectively, the guide step 202 comprises an upper guide step 2021 and a lower guide step 2022 which are arranged up and down, the upper door body 101 and the lower door body 102 relatively slide on the guide step 202, namely, the upper door body 101 transversely slides on the upper guide step 2021, and the lower door body 102 transversely slides on the lower guide step 2022, so that the upper door body 201 and the lower door body 102 comprise an open state and an overlapped state.

In general, when the upper door body 101 and the lower door body 102 are in an overlapped state, the distance between the upper door body 101 and the lower door body 102 is reduced, so that a safety hazard of a grip may occur. In the refrigeration equipment of the invention, the stop mechanism 7 is arranged between the upper door body 101 and the lower door body 102, and as shown in fig. 2 to 7, in the overlapped state, the stop mechanism 7 enables the distance between the same side edges of the upper door body 101 and the lower door body 102 to be not smaller than the preset distance, that is, the stop mechanism 7 can limit the upper door body 101 or the lower door body 102 to move towards each other, so that the distance between the same side edges of the upper door body 101 and the lower door body 102 is the safe distance for preventing the hand from being clamped, and the condition that the hand is clamped by a user is avoided.

Further, the refrigeration apparatus further includes a handle 5 fixed to the lower door body 102, the handle 5 being located at a side of the lower door body 102 away from the upper door body 101, and the preset distance is a distance from the handle 5 to the upper door body 101 in the overlapped state, that is, a hand of a user is not clamped to the hand by the upper door body 101 when holding the handle 5 on the lower door body 102.

Specifically, the upper door body 101 and the lower door body 102 each include a door panel, a side frame 2 surrounding the side edge of the door panel and extending along a direction perpendicular to the sliding direction, and a transverse frame 1 arranged at the side edge of the door panel 10 and connected with the same ends of the two side frames 2, and the handle 5 of the lower door body 102 is arranged on the side frame 2 of the lower door body 102 far away from the upper door body 101. Correspondingly, the side frames 2 of the upper door body 101 are also provided with handles 5, and the handles 5 of the upper door body 101 and the handles 5 of the lower door body 102 are respectively arranged on the two opposite side frames 2 of the door body 100, so that the door body 100 is convenient to use.

It will be appreciated that the preset distance may be the distance from the handle 5 of the upper door body 101 to the side frame 2 of the lower door body, and the stop mechanism 7 may also prevent the user from being pinched by the side frame 2 of the lower door body 102 when the user's hand is on the handle 5 of the upper door body 101.

As another preferred embodiment of the present invention, as shown in fig. 2 to 7, the stopping mechanism 7 includes a stopping arm 71 and a stopping seat 72 that are matched with each other, where the stopping arm 71 and the stopping seat 72 are respectively disposed on the corresponding side frames 2 of the lower door body 102 and the upper door body 101, that is, the stopping seat 72 has a stopping limiting function on the stopping arm 71, or the stopping arm 71 has a stopping limiting function on the stopping seat 72, which depends on the sliding direction of the door body 100. Of course, the stop arm 71 and the stop seat 72 may be disposed at other positions of the door body 100, so long as the purpose of stopping and limiting is achieved.

As a preferred embodiment of the present invention, the stop seat 72 is disposed on the side frame 2 of the upper door body 101 and extends downward, the stop arm 71 is disposed on the side portion of the side frame 2 of the lower door body 102 and extends toward the upper door body 101, when the lower door body 102 carries the stop arm 71 to slide toward the upper door body 101 to an overlapping state, the stop arm 71 is limited by the stop seat 72, and further the lower door body 102 is limited to slide, because the end of the stop arm 71 exceeds the side frame 2 of the lower door body 102, when the stop arm 71 is limited by the stop seat 72, a distance between the side frame 2 of the lower door body 102 and the stop seat 72, that is, a length of the stop arm 71 is equal, and accordingly, a distance between the handle 5 disposed on the side frame 2 of the lower door body 102 far from the stop arm 71 and the side frame 2 of the upper door body is increased by a length of the stop arm 71, so as to provide a sufficient space for the periphery of the handle 5, so as to prevent the occurrence of a clamping condition.

In this embodiment, the stop seat 72 is preferably provided on one side near the outer edge of the side frame 2 to provide sufficient safety space for the handle 5.

Specifically, referring to fig. 6 and 7, the stop seat 72 has a stop surface 721 that cooperates with the stop arm 71, and an included angle between the stop surface 721 and a plane on which the side frame 1 is located is greater than 90 °, so that the stop seat 72 not only limits the lower door 102 in the sliding direction, but also limits the lower door 102 in the up-down direction, so as to ensure the sliding safety of the lower door 102.

Preferably, the stop surface 721 is disposed perpendicular to the lower surface of the side frame 2, so as to reduce the volume of the side frame 2 occupied by the stop seat 72,

in this embodiment, the stop seat 72 includes a pair of side plates 722 extending from two ends of the stop surface 721 in a direction away from the door panel, so that the stop surface 721 and the side plates 722 form a right triangle shape and are fixed on the side frame 2, so as to enhance the stability of the stop seat 72.

According to the side frame 2 disclosed by the invention, due to the fact that more injection materials are needed at the stop seat 72, the ejector pins of the grinding tool needed for injection molding are abutted against the preformed position of the stop seat 72, and due to the fact that the diameter of the ejector pins is smaller, the ejector pins are inevitably bent or inclined to deform, if the ejector pins are not replaced in time, the situation that the thickness of the area of the side frame 2 close to the stop seat 72 is uneven in the subsequent injection molding process of the side frame 2 can be caused, the quality of the side frame 2 is affected, even the situation that a die is scrapped can be caused, the production cost of the side frame 2 is increased, namely the service life of the die is prolonged, and the production cost of the side frame 2 is reduced.

In order to solve the above-mentioned problem, in the present embodiment, a positioning hole (not shown) is provided between the pair of side plates 722 of the side frame 2, and the mold ejector pin is inserted into the positioning hole, and the depth direction of the positioning hole is along the thickness direction of the side frame 2 to limit the ejector pin from deforming in the length direction thereof, so as to improve the product quality of the side frame 2.

In this embodiment, the positioning hole penetrates through the side frame 2, and in the door panel installation process, whether the filling condition of glue is qualified or not can be determined by positioning Kong Guancha.

Further, as shown in fig. 4 and 5, a side of the stop arm 71 facing away from the side frame 2 has a abutting surface 712, and when the lower door body 102 and the upper door body 101 are in an overlapped state, the abutting surface 711 abuts against the stop surface 721 to limit the relative movement of the door body 100.

Further, the stop arm 71 has a fixing surface 712 fixed to the side frame 2, the area of the fixing surface 712 is larger than the area of the abutting surface 711, and the larger area is used as the fixing surface 712 for connecting and fixing the stop arm 71 to the side frame 2, so that the contact between the stop arm 71 and the side frame 2 can be increased, and the stability of the stop arm 71 is improved in the process of stopping and limiting the lower door 102.

In this embodiment, the whole stop arm 71 is triangular and integrally formed in the length direction of the side frame 2, and the thickness of the stop arm 71 is consistent with the thickness of the side frame 2, so that the stop arm 71 does not increase the downward space of the lower door 102, and the storage space of the refrigeration device is not affected.
