[0029] An embodiment of the utility model provides a door body, which is generally used in a refrigeration device. The refrigeration device includes a box body and the door body described below. Therefore, the utility model also provides a refrigeration device.

[0030] like Figures 1 to 5 As shown, the aforementioned door body includes a door shell 1 and decorative strips 2 arranged at the top and bottom of the door shell 1, the decorative strips 2 are provided with a snap-in groove 21 opening toward the door shell 1, the top and bottom of the door shell 1 are arranged in the snap-in groove 21, the snap-in groove 21 includes a bottom wall 213, a first side wall 211 and a second side wall 212, and in the thickness direction of the door body, the distance between the end of the first side wall 211 away from the bottom wall 213 and the end of the second side wall 212 away from the bottom wall 213 is less than the thickness of the door shell 1.

[0031] The door shell 1 is directly connected to the decorative strip 2 by being inserted into the snap-in groove 21, and the distance between the end of the first side wall 211 away from the bottom wall 213 and the end of the second side wall 212 away from the bottom wall 213 is less than the thickness of the door shell 1, so that when the door shell 1 is inserted into the snap-in groove 21, the first side wall 211 and the second side wall 212 of the snap-in groove 21 are interference fit with the door shell 1, and there is no need to use snaps or screws for fixing, thus avoiding the problem of complicated processing of the decorative strip 2. In addition, due to the interference fit, there is no need to perform sealing operation when the door body is foamed.

[0032] Specifically, Figure 3 , 4 In the embodiment, taking the bottom of the door body as an example, a protrusion 2111 is provided on the side of the first side wall 211 away from the end of the bottom wall 213 and close to the second side wall 212. In the thickness direction of the door body, the distance between the protrusion 2111 and the second side wall 212 is less than the thickness of the door shell 1. The protrusion 2111 is provided at the end of the first side wall 211, so that the distance between the protrusion 2111 and the second side wall 212 is less than the distance of the door shell 1. When the door shell 1 is inserted into the clamping groove 21, one side of the first side wall 211 only contacts the door shell 1 through the protrusion 2111, and the contact area is small. The force generated by the interference fit is all concentrated on the top of the protrusion 2111, so that the door shell 1 and the first side wall 211 are more tightly connected.

[0033] Of course, a protrusion 2111 may be provided on the second side wall 212, or other methods may be used to make the distance between the end of the first side wall 211 away from the bottom wall 213 and the end of the second side wall 212 away from the bottom wall 213 smaller than the thickness of the door shell 1. For example, in the direction from the bottom wall 213 to the opening of the snap-in groove 21, the distance between the first side wall 211 and the second side wall 212 gradually decreases until the distance between the end portions (away from the end of the bottom wall 213) is smaller than the thickness of the door shell 1.

[0034] Furthermore, the first side wall 211 is arranged on the inner side of the door shell 1, and the second side wall 212 is arranged on the outer side of the door shell 1, that is, one side of the door shell 1 and the protrusion 2111 are abutted on the inner side of the door shell 1. Due to the existence of the protrusion 2111, when the door shell 1 is inserted into the clamping groove 21, the first side wall 211 presses the protrusion 2111 against the inner side of the door shell 1 under the action of elasticity. The contact area between the protrusion 2111 and the inner side of the door shell 1 is small, and the abutting force is large, which can better prevent the foaming material from overflowing.

[0035] Preferably, in a direction from the opening of the clamping groove 21 to the bottom wall 213 , the protrusion 2111 is inclined from an end away from the first side wall 211 to an end close to the first side wall 211 .

[0036] like Figure 4 In the figure, the protrusion 2111 is inclinedly extended from one end away from the first side wall 211 to one end close to the first side wall 211, and the protrusion 2111 is inclinedly extended on both the side close to the bottom wall 213 and the side away from the bottom wall 213. When the door shell 1 is plugged in, the inclined surface formed by the inclined extension has a guiding effect on the door shell 1, and the end portion (including the top and the bottom end) of the door shell 1 abuts against the inclined surface and enters the snap-in groove 21 along the inclined surface.

[0037] Furthermore, in the length direction of the door body, the length of the first side wall 211 is greater than the length of the second side wall 212 . The longer length of the first side wall 211 makes it more convenient to connect the door shell 1 and the decorative strip 2 .

[0038] In some embodiments, a plurality of clamping ribs 2112 are provided on the first side wall 211 close to the second side wall 212 , and in the thickness direction of the door body, the distance between the clamping ribs 2112 and the second side wall 212 is equal to the thickness of the door shell 1 .

[0039] To facilitate the clamping of the door shell 1, the distance between the first side wall 211 and the second side wall 212 is usually set to be thicker than the thickness of the door shell 1, so as to prevent the door shell 1 from having difficulty entering the opening of the clamping groove 21. A clamping rib 2112 is set on the side of the first side wall 211 close to the second side wall 212, that is, inside the clamping groove 21, and the distance between the clamping rib 2112 and the second side wall 212 is equal to the thickness of the door shell 1, which can well clamp the door shell 1 in the clamping groove 21 and play a fixing role.

[0040] Furthermore, from the bottom wall 213 to the opening direction, the clamping rib 2112 is arranged to be inclined near one end of the opening and close to the first side wall 211. In other words, in the direction from the opening of the clamping groove 21 to the bottom wall 213, the end of the clamping rib 2112 near one end of the opening gradually extends obliquely toward the second side wall 212 until the distance between the clamping rib 2112 and the second side wall 212 is equal to the width of the door shell 1. The oblique extension of the clamping rib 2112 near one end of the opening plays a guiding role for the door shell 1, thereby preventing the problem that the door shell 1 cannot be inserted into the clamping groove 21 due to size error.

[0041] Preferably, a plurality of clamping ribs 2112 are spaced apart along the width direction of the door body. The spaced apart arrangement of the plurality of clamping ribs 2112 can prevent the door shell 1 from deflecting in the snap-in groove 21 on the one hand, and can also enhance the strength of the first snap-in groove 21 on the other hand.

[0042] When the clamping rib 2112 and the protrusion 2111 are provided at the same time, the end portion (including the top and bottom ends) of the door shell 1 deflects toward the first side wall 211, enters the clamping groove 21 under the guidance of the inclined surface formed by the protrusion 2111, and is then clamped between the clamping rib 2112 and the second side wall 212 under the guidance of the clamping rib 2112. The door shell 1 is connected to the decorative strip 2 under the dual action of the clamping rib 2112 and the protrusion 2111, and the decorative strip 2 has a simple structure and is tightly connected.

[0043] In some embodiments, the door shell 1 includes a shell body 11 and a first shell side wall 12 and a second shell side wall 13 connected to the shell body 11. The shell body 11 is formed as the outer wall of the door body, and the first shell side wall 12 and the second shell side wall 13 are respectively bent inward along both sides of the length of the shell body 11 to form two side walls of the door body. The decorative strip 2 is provided with snap-in grooves 21 at the top and bottom corresponding to the shell body 11, the first shell side wall 12 and the second shell side wall 13.

[0044] The door shell 1 only needs to be bent on two sides, which is simpler than the common four-side bending structure. After being bent, the door shell 1 forms three panels, namely, the shell body 11, the first shell side wall 12 and the second shell side wall 13. The three panels all need to be snapped with the decorative strip 2. Therefore, three snap-in grooves 21 are provided on the decorative strip 2. The shell body 11, the first shell side wall 12 and the second shell side wall 13 are all snapped with the snap-in grooves 21 of the decorative strip 2, so that the three surfaces of the door shell 1 are snapped with the snap-in grooves 21, and no other connection structure is required.

[0045] Since the door shell 1 is formed into three sections after being bent, wherein the first shell side wall 12 and the second shell side wall 13 are arranged opposite to each other, the door shell 1 needs to be installed with the aid of the inclined surface of the protrusion 2111 away from the bottom wall 213 as a guide.

[0046] Furthermore, the door body provided by the present invention also includes a door lining 3, the top and bottom of the door lining 3 are connected to the decorative strip 2, and the two sides are connected to the first shell side wall 12 and the second shell side wall 13 respectively.

[0047] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0048] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
