[0039] The embodiment of the present utility model provides a door body, which is generally used as the door body of a refrigeration device. The refrigeration device includes a box body and this door body. Thus, the present utility model also provides a refrigeration device provided with the aforementioned door body.

[0040] As Figure 3 、 4 shown, the aforementioned door body includes a door body 1, a vertical beam 2 connected to the door body 1, a connecting member 3 connecting the door body 1 and the vertical beam 2, and a spring piece 4 with both ends respectively fixed to the vertical beam 2 and the connecting member 3. The vertical beam 2 rotates around an axis, and the spring piece 4 extends or contracts as the vertical beam 2 rotates.

[0041] The vertical beam 2 of the door body provided by the present utility model is connected to the door body 1 through the connecting member 3, and at the same time, a spring piece 4 with both ends respectively fixed to the vertical beam 2 and the connecting member 3 is also provided. When the vertical beam 2 rotates around the axis, the end of the spring piece 4 fixed to the vertical beam 2 rotates around the end of the spring piece 4 fixed to the connecting member 3. During the rotation of the vertical beam 2, the spring piece 4 will extend or contract, thereby driving and restricting the rotation of the vertical beam 2.

[0042] A guide groove is provided on the box body of the refrigeration equipment, which is used to guide and limit the movement of the vertical beam 2 when closing the door. When the door body is closed, one end of the vertical beam 2 gradually enters the guide groove from the opening of the guide groove, and the spring 4 rotates under the drive of the vertical beam 2, and is stretched or contracted by force; when the door body is opened, the vertical beam 2 gradually withdraws from the guide groove. When the vertical beam 2 loses the limiting effect of the guide groove, the spring 4 loses its force and restores its original shape, driving the vertical beam 2 to rotate to a set angle relative to the door body 1, so that the vertical beam 2 cannot rotate at will when the door body is open. If the vertical beam 2 rotates to the relative position of the vertical beam 2 and the door body 1 when the door body is closed, it will cause the door body to be unable to close. The aforementioned vertical beam 2 rotates to a set angle relative to the door body 1, and the set angle can be set by adjusting the original shape of the spring 4 and the position of the two ends of the spring 4.

[0043] In some embodiments, the vertical beam 2 is provided with a clearance cavity 21, one of the top and bottom of the clearance cavity 21 is provided with a fixing groove 213, and the other is provided with a fixing notch 214, and the fixing notch 214 is open toward the fixing groove 213 and toward the horizontal direction; the connecting member 3 includes a rotating shaft 31 connected to the vertical beam 2, and the top and bottom ends of the rotating shaft 31 are arranged in the fixing groove 213 or the fixing notch 214.

[0044] The opening of the clearance cavity 21 is set as follows: when the door body closes the box body, the opening of the clearance cavity 21 opens toward the door body 1 and the box body, so as to make way when the vertical beam 2 and the connecting member 3 rotate relative to each other. Figure 9 In the figure, the clearance cavity 21 includes a first clearance cavity 211 and a second clearance cavity 212. The first clearance cavity 211 is used to accommodate the upper half of the rotating shaft 31, and the second accommodation cavity accommodates the middle part of the rotating shaft 31, the first fixing part 32 and the spring 4 mentioned below. The top of the first clearance cavity 211 is provided with a fixing groove 213 with an opening facing downward, and the bottom of the second clearance cavity 212 is provided with a fixing notch 214, which opens upward and horizontally. When the connecting member 3 is connected to the vertical beam 2, the top end of the rotating shaft 31 is tilted and extended into the fixing groove 213, and then the bottom end of the rotating shaft 31 is pushed into the fixing notch 214 from the horizontal opening of the fixing notch 214 to realize the connection between the connecting member 3 and the vertical beam 2. The axis of rotation of the vertical beam 2 is the central axis of the rotating shaft 31.

[0045] Of course, a fixing groove 213 with an upward opening may be provided at the bottom of the clearance cavity 21, and a fixing notch 214 may be provided at the top of the clearance cavity 21, and the fixing notch 214 may open downward and horizontally. In this case, when the connecting member 3 needs to be connected to the vertical beam 2, the bottom end of the rotating shaft 31 is tilted and extended into the fixing groove 213, and then the top end of the rotating shaft 31 is pushed into the fixing notch 214 from the horizontal opening of the fixing notch 214, so as to realize the connection between the connecting member 3 and the vertical beam 2.

[0046] In some embodiments, the connecting member 3 further includes a first fixing portion 32 connected to the rotating shaft 31 , the spring sheet 4 is arc-shaped, and the rotating shaft 31 and the first fixing portion 32 are arranged on a curved side of the spring sheet 4 .

[0047] like Figure 3 , 4 In the front-to-back direction of the refrigeration equipment, the first fixing portion 32 is located at the rear side relative to the rotating shaft 31; in the left-to-right direction, the first fixing portion 32 is located at the side of the rotating shaft 31 away from the vertical beam 2 relative to the rotating shaft 31. The spring piece 4 surrounds the rotating shaft 31 and is arranged between the rotating shaft 31 and the inner wall of the clearance cavity 21. When the door body and the vertical beam 2 are both regarded as planes, when the door body closes the box body, the vertical beam 2 and the door body are arranged relatively parallel, and the spring piece 4 is stretched by force; when the door body opens the box body, the spring piece 4 loses the force and shrinks to restore its original shape, and drives the vertical beam 2 to rotate to be roughly perpendicular to the door body. Among them, in the aforementioned front-to-back direction, the side where the door body is located is the front, the side where the box body is located is the back, and the left-to-right direction is a horizontal direction perpendicular to the front-to-back direction.

[0048] In some embodiments, the vertical beam 2 is provided with a first notch 2151; the first fixing portion 32 is provided with a second notch 321; the spring sheet 4 includes a first end 41 and a second end 42, the first end 41 and the second end 42 are bent toward the bending direction of the spring sheet 4 and are respectively arranged in the first notch 2151 and the second notch 321.

[0049] The vertical beam 2 is provided with a fixing column 215, which is arranged in the clearance cavity 21 and is provided with the aforementioned first notch 2151. The fixing column 215 is located in the clearance cavity 21 at a position close to one end of the door body 1 and away from one end of the box body (relative to when the door body closes the box body). The first notch 2151 is arranged on the fixing column 215, and the second notch 321 is arranged at the end of the first fixing part 32 away from the rotating shaft 31. The spring 4 bends the first end 41 and the second end 42 in the bending direction of the spring 4, so that the two ends of the spring 4 form a hook shape, and the first end 41 and the second end 42 are respectively fixed to the first notch 2151 on the vertical beam 2 and the second notch 321 on the first fixing part 32, and the fixing is achieved by using the hook shape. When the resilience of the spring 4 is weak and needs to be replaced, it can be easily removed by simply taking out the second end 42 of the spring 4 from the second notch 321.

[0050] In some embodiments, the connector 3 includes a second fixing portion 33 connected to the door body 1, and the door body 1 is provided with a stopper 13 connected to the second fixing portion 33. By providing the stopper 13 on the door body 1 for connecting with the connector 3, the connector 3 and the door body 1 can be detachably connected, and the connector 3 can be disassembled and replaced when it is damaged and needs to be replaced. Of course, the connector 3 can also be directly fixed by gluing or integrally formed with the door body 1.

[0051] In some embodiments, the limiting member 13 includes a first limiting portion 131 connected to the second fixing portion 33 and a second limiting portion 132 connected to the first limiting portion 131; the door body 1 is provided with a relief hole 121 formed to cooperate with the first limiting portion 131, the first limiting portion 131 passes through the relief hole 121 from inside the door body 1, and the second limiting portion 132 is attached to the inner wall surface of the door body 1.

[0052] The door body 1 includes a housing 11 and a lining 12. The lining 12 forms a receiving cavity that opens toward the side of the box body and is used for placing a bottle holder, etc., such that the cross-sections of both ends of the lining 12 close to and far from the vertical beam 2 are U-shaped. The relief hole 121 is opened in the lining 12 and faces the vertical beam 2 (when the door closes the box body). The shape of the second limiting portion 132 matches the shape of the lining 12 at the relief hole 121. After the first limiting portion 131 passes through the relief hole 121 from inside the door body 1, the second limiting portion 132 is attached to the inner side of the lining 12 to prevent the foaming material from overflowing during the foaming of the door body. Herein, the inside of the door body 1 refers to the cavity formed by the housing 11 and the lining 12.

[0053] In some embodiments, the second fixing portion 33 is provided with a limiting groove 331 whose horizontal opening faces the first limiting portion 131, and the opening area of the limiting groove 331 is smaller than the area of the bottom wall at the end far from the opening; the shape of the first limiting portion 131 matches the shape of the limiting groove 331.

[0054] Specifically, in this text, the length direction of the second fixing portion 33 is the vertical direction, the width direction of the second fixing portion 33 is the front-back direction, and the thickness direction of the second fixing portion 33 is the left-right direction, which is also the depth direction of the limiting groove 331. When the two sides of the opening of the limiting groove 331 extend in the depth direction, they simultaneously extend obliquely in the width direction such that the area of the bottom wall of the limiting groove 331 is larger than the opening area. As shown in Figure 4 、 8 After the limiting member 13 is installed on the door body 1, after the first limiting portion 131 passes through the relief hole 121, the two ends of the first limiting portion 131 extend obliquely in the front-back direction, such that the area of the end of the first limiting portion 131 far from the relief hole 121 is larger than the area of the end close to the relief hole 121, so that the cross-section of the first limiting portion 131 matches the cross-sectional shape of the limiting groove 331.

[0055] When the connecting member 3 is connected to the limiting member 13, after the connecting member 3 aligns the limiting groove 331 with the first limiting portion 131 in the vertical direction, the connecting member 3 is moved in the vertical direction such that the first limiting portion 131 is located in the limiting groove 331 to achieve the connection.

[0056] In some embodiments, the top of the limiting groove 331 is closed and the bottom is open. Thus, when the connecting member 3 is connected to the limiting member 13, the bottom of the limiting groove 331 needs to be aligned with the first limiting portion 131, and then the connecting member 3 is moved downward. Since the top of the limiting groove 331 is closed, it can prevent the connecting member 3 from slipping downward. Of course, the top and bottom of the limiting groove 331 can also be both open, or the top of the limiting groove 331 is open and the bottom is closed. In these two cases, after the connecting member 3 is installed on the limiting member 13, additional fixing means need to be taken to prevent the first limiting portion 131 from completely passing through the limiting groove 331 and causing the connecting member 3 to fall off.

[0057] In some embodiments, the elastic piece 4 is provided with a telescopic hole 43 for increasing the elasticity of the elastic piece 4 and preventing the elastic piece 4 from being twisted and deformed in the stretched state.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
