[0020] The present application discloses a size-adjustable storage support, such as Figure 1 As shown, it comprises an outer support 1, a storage unit 2, an ejection device, a guide rail 3 and a stopper 4. In combination with Figure 2 and Figure 3 As shown, the outer support 1 comprises a left side plate 101, a right side plate 102 and a connecting part 103 between the left side plate 101 and the right side plate 102, the rear sides of the left side plate 101, the right side plate 102 and the connecting part 103 are fixedly connected by four connecting plates 105 arranged from top to bottom in sequence, respectively, and the front ends of the top and bottom of the left side plate 101, the right side plate 102 and the connecting part 103 are fixedly connected by a cross beam 104. The left side plate 101 and the right side plate 102 each have three groups of circular ventilation holes, each group comprising two rows of ventilation holes. The connecting part 103 is in the shape of a cuboid with a cavity inside, and each face of the connecting part 103 has a plurality of uniformly arranged circular ventilation holes. The left side plate 101 and the connecting part 103 can form a left cavity inside the outer support 1, and the right side plate 102 and the connecting part 103 can form a right cavity inside the outer support 1. The left side plate 101 and the right side plate 102 each have a plurality of oblong holes on the upper and lower sides of the ventilation holes, and the connecting part 103 corresponding to the left side plate 101 and the right side plate 102 also has oblong holes. The connecting part 103 can facilitate the circulation of cold air in the left cavity and the right cavity, enhancing the refrigeration effect. The guide rail 3 comprises a sliding rail and a sliding channel, and the sliding rail is detachably fixedly connected with the storage unit 2. The sliding channel is detachably fixedly connected with the outer support 1 through the oblong holes, and the gap between the storage units 2 can be adjusted later to improve the aesthetic appearance of the product. The ejection device is fixedly connected to the inner wall of the rear side of the outer support 1, and the ejection device comprises a spring. The storage unit 2 and the stopper 4 cooperate to cause the ejection device to elastically deform.

[0021] The storage unit 2 is in the shape of a square box with the top and front open, and the front end of the left side wall, the right side wall and the bottom wall of each storage unit 2 has an inward bend. The storage unit 2 has a storage unit clamping part 201 in the shape of a same-direction double bend, and the two vertical ends of the storage unit clamping part 201 are fixedly connected with the lower bottom surface of the storage unit 2 in the front-rear direction. The storage unit 2 is fixedly connected in the left cavity and the right cavity through the guide rail 3.

[0022] As Figure 4As shown, the position limiter 4 comprises a top plate, a bottom plate, a rotating part 401 and a position limiter clamping part 402, the top plate and the bottom plate are clamped to form a containing cavity, the rotating part 401 and the position limiter clamping part 402 are located in the containing cavity. The position limiter 4 is fixed on the connecting plate 105 at the rear side of the left cavity and the right cavity respectively, and the front part of the top plate and the bottom plate of the position limiter 4 is provided with a U-shaped opening facing the front side. The rotating part 401 located in the left cavity position limiter 4 is located at the left side of the U-shaped opening, and the position limiter clamping part 402 is located at the left side of the rotating part 401; the rotating part 401 located in the right cavity position limiter 4 is located at the right side of the U-shaped opening, and the position limiter clamping part 402 is located at the right side of the rotating part 401. As shown in Figure 5 As shown, the rotating part 401 is movably connected with the top plate, and the rotating part 401 comprises four tooth bars which are bent in the same direction, each tooth bar has a clamping opening which is matched with the storage unit clamping part 201, and each tooth bar is located below the middle part of the U-shaped opening when the rotating part 401 rotates, and the clamping opening faces the front side.

[0023] The front right side edge of the rotating part 401 located in the left cavity has an arc-shaped notch which is matched with the rotating part 401, and the front left side of the position limiter clamping part 402 can be clamped with the end face of the tooth bar. The front left side edge of the rotating part 401 located in the right cavity has an arc-shaped notch which is matched with the rotating part 401, and the front right side of the position limiter clamping part 402 can be clamped with the end face of the tooth bar. The storage unit 2 is releasably fixedly connected with the outer support 1 through the cooperation of the storage unit clamping part 201, the tooth bar, the clamping opening and the position limiter clamping part 402.

[0024] The working principle of the present application is that when the storage unit 2 in the left cavity is closed, the left and right sides of each storage unit 2 are fixedly connected with slide rails, which move into the outer support 1 along the slide. When the storage unit clamping part 201 at the bottom of the storage unit 2 in the left cavity is pushed to the rear side of the left cavity, it is clamped into the clamping interface of the rotating part 401 through the U-shaped mouth of the top plate and the bottom plate, and the rack is pushed to make the rotating part 401 rotate clockwise. When the rotating part 401 rotates, the edge of the rack can pass through the arc-shaped gap of the limiter clamping part 402. When the rack of the rotating part 401 rotates counterclockwise, its end face can be clamped by the limiter clamping part 402, so that the rotating part 401 cannot rotate counterclockwise. When the storage unit clamping part 201 is pushed to the rear side of the U-shaped mouth, it will be clamped by the rack and the U-shaped mouth at the same time. When the storage unit 2 is pushed into the U-shaped mouth, the ejection device fixed to the rear side of the guide rail 3 is in contact with the connecting plate 105 and is elastically deformed. When the storage unit 2 in the left cavity is opened, the limiter clamping part 402 is controlled by electromagnetism, and the switch is pressed to make the storage unit clamping part 201 rotate left around its rear part as the axis, and at the same time, the elastic deformation of the ejection device is converted into elastic potential energy to push the storage unit clamping part 201 out of the U-shaped mouth of the limiter 4, and at this time the rack of the rotating part 401 can rotate counterclockwise until the storage unit 2 moves to the front side of the left cavity through the guide rail 3.

[0025] The specific structure and function involved in the closing and opening of the storage unit 2 in the right cavity are as described above, and the only difference is that the positions of the rotating part 401 and the storage unit clamping part 201 relative to the U-shaped mouth are different. It should be noted that the clamping interface of the rotating part 401 and the U-shaped mouth should face the front side. The positions of the rotating part 401 and the limiter clamping part 402 in the left and right cavities are different, and in order to facilitate the lead wire to be led out from the connecting part 103, the disorder of the lead wire is avoided to affect the appearance.

[0026] It should be noted that in the present application, unless otherwise specified and limited, the terms "installation", "connection", "fixation", "middle part" and the like should be understood broadly; the terms such as "front", "rear", "left", "right", "top" and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only a relationship word determined for the purpose of describing the structural relationship of the components of the present application, and cannot be understood as a limitation on the present application.

[0027] Of course, the above description is not a limitation on the present application, and the present application is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essential scope of the present application should also be within the protection scope of the present application.
