Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically a refrigerator for high-speed rail. Background Technology

[0002] High-speed rail refrigerators refer to ultra-small refrigeration devices that comply with railway regulations. They are compact and portable refrigeration equipment mainly used for outdoor camping, travel, and office use, but can also be used in homes. When used on high-speed trains, they need to be stored in designated locations to avoid blocking passageways. However, if the storage area has large gaps, the refrigerator may slide and collide during the train's acceleration or deceleration, affecting the items stored inside. Furthermore, when repairing the internal refrigeration system control module, it is usually necessary to disassemble the back cover, which typically requires a specific type of screwdriver, making the process rather cumbersome.

[0003] Based on this, a refrigerator for high-speed rail is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0004] The purpose of this invention is to provide a refrigerator for high-speed trains to solve the problems in the background art.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] In one embodiment, such as Figures 1-4 As shown, a refrigerator for high-speed rail includes a refrigerator body 1. A door 11 is rotatably connected to the side wall of the refrigerator body 1. A T-shaped groove is provided on the refrigerator body 1. Fixing blocks 12 are evenly fixedly connected to the four corners of the bottom of the refrigerator body 1. A rubber buffer pad 13 is provided at the bottom of the fixing block 12. An internal thread hole is provided on the rubber buffer pad 13, and a fixing bolt 14 is internally threaded into the internal thread hole. The top of the fixing bolt 14 is threadedly connected to the inner wall of the fixing block 12. A wire mesh cover 15 is provided on the side wall of the refrigerator body 1. A quick-release component 2 is provided on the side wall of the wire mesh cover 15. An anti-slip component 3 is provided at the bottom of the refrigerator body 1.

[0021] In one embodiment, the anti-slip component 3 supports the refrigerator body 1, thereby improving the stability of the refrigerator body 1 and effectively suppressing the displacement risk under the acceleration and deceleration conditions of high-speed trains. When it is necessary to inspect the refrigeration system control module inside the refrigerator body 1, the wire mesh cover 15 can be removed by canceling the restriction of the quick-release component 2 on the wire mesh cover 15, and the refrigeration system control module inside the refrigerator body 1 can be inspected.

[0022] In an optional embodiment, such as Figure 3 As shown, the quick-release assembly 2 includes a pull ring 21 and a connecting block 23. A pull rod 22 is rotatably connected to the top of the pull ring 21. The pull rod 22 is slidably connected to a groove on the wire mesh cover 15. A guide groove is provided on the pull rod 22. The connecting block 23 is fixedly connected to the side wall of the wire mesh cover 15. A rectangular groove is provided on the connecting block 23, and guide blocks are symmetrically fixedly connected in the rectangular groove. The guide blocks slide in cooperation with the guide groove on the pull rod 22. When the pull ring 21 is pulled, the pull rod 22 moves synchronously. During the movement of the pull rod 22, the guide blocks slide in the guide groove on the pull rod 22 to limit and guide the pull rod 22, so that the pull rod 22 will not deviate or fall off when it moves.

[0023] In an optional embodiment, such as Figure 3 As shown, elastic plates 24 are symmetrically fixedly connected to the side wall of the connecting block 23. The connecting block 23 and the elastic plate 24 are slidably connected to the narrow diameter section of the T-shaped groove opened on the refrigerator body 1. A locking block 25 is fixedly connected to the side wall of the elastic plate 24. The locking block 25 is engaged with the wide diameter section of the T-shaped groove opened on the refrigerator body 1. The end of the pull rod 22 near the elastic plate 24 is rotatably connected to the movable rod 26. The end of the movable rod 26 away from the pull rod 22 is rotatably connected to the side wall of the elastic plate 24. When the pull rod 22 moves, it pulls the movable rod 26 to move, causing the movable rod 26 to pull the elastic plate 24 to deform, so that the locking block 25 is no longer engaged with the T-shaped groove. Then the wire mesh cover 15 can be pulled to make the connecting block 23 and the elastic plate 24 no longer contact the T-shaped groove. In this way, the wire mesh cover 15 can be removed to inspect the refrigeration system control module inside the refrigerator body 1.

[0024] In an optional embodiment, such as Figure 4 As shown, the anti-slip component 3 includes a right-angle plate 31. A positioning block 32 is fixedly connected to the side wall of the right-angle plate 31. The positioning block 32 is inserted into a positioning hole opened on the fixed block 12. A sliding rod 33 is fixedly connected to the side wall of the right-angle plate 31. The sliding rod 33 is rotatably connected to the inner wall of the fixed block 12. A rotating rod 35 is sleeved on the outer wall of the sliding rod 33. A spring 34 is fixedly connected to the side wall of the sliding rod 33. The spring 34 is fixedly connected to a sliding groove opened on the rotating rod 35. A support block 36 is fixedly connected to the outer wall of the rotating rod 35. Pulling the right-angle plate 31 causes the positioning block 32 to no longer be inserted into the positioning hole. At the same time, the right-angle plate 31 drives the sliding rod 33 to move synchronously, causing the spring 34 to stretch. Then, the right-angle plate 31 is rotated ninety degrees, causing the right-angle plate 31 to drive the sliding rod 33 to rotate synchronously. The sliding rod 33 drives the rotating rod 35 to rotate synchronously. The rotating rod 35 drives the support block 36 to rotate synchronously, thereby making the side wall of the support block 36 with anti-slip ridges contact the tabletop.

[0025] In an optional embodiment, such as Figure 4 As shown, the slide bar 33 is composed of a cylindrical section and a rectangular section connected coaxially. The cross-sectional dimension of the rectangular section is larger than that of the cylindrical section. The groove opened on the rotating rod 35 is adapted to the rectangular section. When the right angle plate 31 drives the slide bar 33 to rotate, the rotating rod 35 is driven to rotate synchronously under the action of the torque force of the rectangular section.

[0026] In an optional embodiment, such as Figure 4 As shown, the bottom end of the support block 36 is evenly provided with anti-slip ridges. The anti-slip ridges at the bottom end of the support block 36 contact the table, increasing the contact area between the refrigerator body 1 and the table, making it more stable and preventing slippage.

[0027] The above embodiment discloses a refrigerator for high-speed rail. When the refrigerator body 1 is placed on the high-speed rail table, pulling the right-angle plate 31 disengages the positioning block 32 from the positioning hole. Simultaneously, the right-angle plate 31 moves the sliding rod 33, stretching the spring 34. Then, rotating the right-angle plate 31 ninety degrees causes the sliding rod 33 to rotate synchronously, which in turn rotates the rotating rod 35. The rotating rod 35 then rotates the support block 36, causing the sidewall of the support block 36 with anti-slip textures to contact the table, thus increasing the contact area between the refrigerator body 1 and the table and preventing significant slippage of the refrigerator body 1 during high-speed rail acceleration or deceleration. Subsequently, when inspection or maintenance of the refrigeration system control module inside the refrigerator body 1 is required, the wire mesh cover 15 is removed, and the pull ring 21 is pulled, causing the pull rod 22 to move synchronously. 2. Moving the movable rod 26 causes the elastic plate 24 to deform, which in turn causes the locking block 25 to move synchronously, so that the locking block 25 is no longer engaged with the T-slot. Then, the wire mesh cover 15 can be pulled, causing the connecting block 23 and the elastic plate 24 to move synchronously, so that the connecting block 23 and the elastic plate 24 are no longer engaged with the T-slot. In this way, the wire mesh cover 15 can be removed, and the refrigeration system control module inside the refrigerator body 1 can be inspected or repaired. In summary, the anti-slip component 3 supports the refrigerator body 1, improving the stability of the refrigerator body 1 and effectively suppressing the displacement risk under the acceleration and deceleration conditions of high-speed trains. When it is necessary to repair the refrigeration system control module inside the refrigerator body 1, the wire mesh cover 15 can be removed by removing the restriction of the quick-release component 2 on the wire mesh cover 15, and the refrigeration system control module inside the refrigerator body 1 can be repaired.

[0028] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
