DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solutions in the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the utility model.

[0027] It should be noted that the terms "upper" and "lower" indicate directions or positional relationships based on the directions or positional relationships shown in the auxiliary figures, and are only for the purpose of simplifying the description of the present invention, rather than indicating or implying that the device referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention. Specifically, in the present invention, the user's operating surface is the front, the direction toward the ground is the bottom, and conversely, the direction away from the ground is the upper, and other descriptions indicating directions are defined based on "upper" and "lower".

[0028] In various drawings of the present invention, for the convenience of illustration, some dimensions of structures or parts are exaggerated relative to other structural parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present invention.

[0029] The utility model provides a locking mechanism 100 and a refrigeration device having the locking mechanism 100, such as Figures 1 to 6 As shown, the refrigeration device includes a first body 200 and a second body 300 , and the locking mechanism 100 is used to lock the first body 200 and the second body 300 .

[0030] like Figures 1 to 3 As shown, the locking mechanism 100 includes a fixing device 10 and a connecting device 20. The fixing device 10 is used to be fixed on the first body 200, and the connecting device 20 is used to be fixed on the second body 300 and cooperate with the fixing device 10 to lock the first body 200 and the second body 300.

[0031] like Figure 2 and Figure 3 As shown, the fixing device 10 includes a base 11 and an elastic structure 12 movably connected to the base 11. In the arrangement direction of the base 11 and the elastic structure 12, when the elastic structure 12 is subjected to the pressure of the connecting device 20, the elastic structure 12 moves relative to the base 11. In the present utility model, the elastic structure 12 is subjected to the pressure of the connecting device 20.

[0032] Specifically, the base 11 includes a base plate 111 and a pair of movable grooves 112 provided at both ends of the base plate 111 along its length, and the movable grooves 112 are used to cooperate with the elastic structure 12 so that the elastic structure 12 can move relative to the base 11. The base plate 111 is used to be fixedly connected to the first body 200 by bolts.

[0033] Preferably, part of the substrate 111 is recessed in a direction away from the connecting device 20 to form a receiving groove 113 for accommodating the elastic structure 12, and the movable groove 112 is arranged at both ends of the bottom wall of the receiving groove 113. When the elastic structure 12 is squeezed, the elastic structure 12 will be deformed or displaced in the receiving groove 113 along the arrangement direction of the base 11 and the elastic structure 12, and will not be displaced in a direction perpendicular to the arrangement direction of the base 11 and the elastic structure 12, that is, the elastic structure 12 is confined in the receiving groove 113.

[0034] In the present invention, the arrangement direction of the elastic structure 12 and the base 11 is defined as the up-down direction, that is, the elastic structure 12 is located above the base 11, and the extension direction of the base 11 is the lateral direction.

[0035] like Figure 2 and Figure 3 As shown, the elastic structure 12 includes a top plate 121 and a pair of elastic arms 123 fixed to the top plate 121 on the side facing the base 11, the top plate 121 is located above the substrate 111 and extends in the same direction as the substrate 111, the elastic arm 123 extends to the base 11 at one end away from the top plate 121, and the elastic arm 123 has at least a free state and a compressed state squeezed by the connecting device 20. Preferably, the elastic arm 123 extends to the bottom wall of the receiving groove 113 at one end away from the top plate 121, and when the elastic structure 12 is squeezed, the elastic structure 12 is confined in the receiving groove 113 to prevent the elastic structure 12 from being displaced in the lateral direction, thereby ensuring the close fit between the connecting device 20 and the fixing device 10, so as to achieve the purpose of locking the first body 200 and the second body 300 with each other and improving the sealing.

[0036] In this embodiment, Figure 1 and Figure 3 As shown, the elastic arm 123 extends obliquely from the top plate 121 toward the base 11, and the elastic arm 123 and the top plate 121 form a stable triangular relationship, and the elastic arm 123 can decompose the pressure into the lateral and vertical directions, so that the elastic structure 12 can withstand greater pressure and improve the service life of the fixing device 200. It can be understood that the elastic arm 123 can be extended obliquely outward in the direction of the base 11, or can be extended obliquely inward in the direction of the base 11, and both can achieve support for the top plate 121.

[0037] Preferably, the elastic structure 12 also includes a support arm 124 located at the end of the elastic arm 123, and the support arm 124 is supported on the substrate 111 along the extension direction of the substrate 111, which can increase the contact area between the elastic structure 12 and the substrate 111. In this embodiment, the support arm 124 extends outward from the end of the elastic arm 123, so that the extension direction of the support arm 124 is the same as the lateral component direction of the elastic arm 123, which is beneficial to the support arm 124 to support the elastic arm 123.

[0038] like Figures 1 to 3 As shown, the elastic structure 12 also includes guide plates 125 located at both ends of the top plate 121 and extending into the movable groove 112, and a limiting portion 126 provided at the end of the guide plate 125 to prevent the guide plate 125 from falling off from the movable groove 112. The guide plates 125 are preferably provided in pair, and a pair of the elastic arms 123 are located between the pair of the guide plates 125. The elastic structure 12 cooperates with the base 11 through the pair of the guide plates 125.

[0039] like Figure 3 As shown, the guide plate 125 includes a first section 1251 connected to the top plate 121, and a second section 1252 connected to the first section 1251 and the limiting portion 126, the width of the first section 1251 is greater than the width of the second section 1252, and the maximum dimension of the outer diameter of the first section 1251 and the limiting portion 126 is not less than the inner diameter dimension of the movable groove 112, so as to limit the movable range of the guide plate 125 relative to the base plate 111.

[0040] The straight-line distance from the elastic arm 123 along the top plate 121 to the bottom wall of the receiving groove 113 is not greater than the length of the guide plate 125 , so that the elastic arm 123 is located in the space between the top plate 121 and the bottom wall of the receiving groove 113 .

[0041] In order to enhance the overall strength of the elastic structure 12 , the elastic structure 12 further includes a reinforcing plate 127 connected to the top plate 121 and the guide plate 125 , and the reinforcing plate 127 is connected to the side of the top plate 121 along the lateral direction.

[0042] As another preferred embodiment of the present invention, Figure 3 As shown, the fixing device 10 also includes a support seat 13 arranged between the base 11 and the elastic structure 12. When the elastic structure 12 is squeezed by the connecting device 20, the support seat 13 is used to support the top plate 121 and limit the distance that the top plate 121 moves toward the base plate 111. After the top plate 121 contacts the support seat 13, the support seat 13 applies a reaction force toward the connecting device 20 to the top plate 121, thereby locking the locking mechanism 100 and improving the sealing between the first body 200 and the second body 300.

[0043] Specifically, the support seat 13 includes a support plate 131 extending in the same direction as the base plate 111, an avoidance space 132 provided on the support plate 131 for the guide plate 125 and the elastic arm 123 to pass through, and a support beam 133 for dividing the avoidance space 132 into two parts. In this embodiment, the reinforcing plate 127 is provided with an avoidance groove 128 for avoiding the support beam 133.

[0044] Furthermore, the support seat 13 also includes a fixing plate 134 for fixing to the first main body 200, the fixing plate 134 is fixed to the side of the support plate 131, and the fixing plate 134 and the base plate 111 are fixed by bolts. When the locking mechanism 100 is installed, the fixing plate 134 and the base plate 111 are fixed to the first main body 200 at the same time by bolts, so as to improve the strength of the combination of the locking mechanism 100 and the first main body 200.

[0045] The support seat 13 further includes a plurality of claws (not shown) disposed on the support plate 131. In this embodiment, the base plate 111 is provided with a plurality of slots 114 that snap fit with the claws to achieve fixed fit between the support seat 13 and the base 11. The claws are spaced apart along the length direction of the support plate 131 to balance the force between the support plate 131 and the base plate 111.

[0046] The width of the support plate 131 is greater than the width of the substrate 111, so that the support plate 131 exceeds the edge of the substrate 111 at a portion of its width. The support seat 13 also includes a handle 135 connected to the side of the support plate 131 away from the fixing plate. The handle 135 and the fixing plate 134 are respectively fixed on both sides of the support plate 131. When the fixing device 20 is fixed on the first body 200, the first body 200 can be operated by the handle 135.

[0047] The connecting device 20 includes a connecting plate 21 for fixing on the second body 300 . The connecting plate 21 extends in the same direction as the base plate 111 . When the connecting device 20 cooperates with the fixing device 10 , the connecting plate 21 is located above the top plate 121 .

[0048] like Figures 1 to 3 As shown, one of the connecting device 20 and the elastic structure 12 has a limiting protrusion 22, and the other has a limiting groove 122 matched with the limiting protrusion 22, so as to lock the fixing device 10 and the connecting device 20 together.

[0049] As a preferred embodiment of the utility model, the limiting protrusion 22 is provided on the connecting device 20, and the limiting groove 122 is provided on the elastic structure 12. Specifically, the limiting protrusion 22 is provided on the connecting plate 21 and extends toward the top plate 121. Preferably, the top surface of the limiting protrusion 22 is a smooth guide surface.

[0050] In this embodiment, the limiting groove 122 is located on the top plate 121. When the connecting device 20 cooperates with the fixing device 10, the connecting device 20 applies pressure to the elastic structure 12 through the limiting protrusion 22. A pair of elastic arms 123 are respectively located on both sides of the limiting groove 122, which can share the pressure borne by the elastic structure 12.

[0051] In this embodiment, the projection positions of the limiting groove 122 and the support beam 133 on the substrate 111 are consistent. When the elastic structure 12 is subjected to pressure, the top plate 121 moves toward the support seat 13, and the position corresponding to the limiting groove 122 on the top plate 121 abuts against the support beam 133.

[0052] Of course, the limiting protrusion 22 is provided on the elastic structure 12 , and the limiting groove 122 is located on the connecting plate 21 , so as to realize the cooperation between the fixing device 10 and the connecting device 20 .

[0053] The utility model provides a refrigeration device, such as Figures 4 to 6 As shown, the refrigeration device includes a first body 200, a second body 300, and a locking mechanism 100 connecting the first body 200 and the second body 300, wherein one of the first body 200 and the second body 300 is a door body, and the other is a box body, that is, the locking mechanism 100 is used to lock the door body and the box body, and improve the sealing between the box body and the door body.

[0054] Preferably, the first body 200 is a door body, the second body 300 is a box body, the refrigeration device further comprises a hinge for rotatably connecting the box body and the door body, the hinge is located at the lower side of the door body, and the locking mechanism 100 is installed at the upper side of the door body. Of course, the first body 200 can also be a box body, and the second body 300 can be a door body.

[0055] It is understandable that the refrigeration device of the present invention can be used alone as a refrigeration appliance, or can be arranged in a large refrigeration appliance to be used as an ice house.

[0056] like Figure 6 As shown, the first main body 200 includes a door outer shell 201, an inner shell 202, and an insulation layer (not shown) between the door outer shell 201 and the door inner shell 202. The door outer shell 201 includes an outer shell 2011 and an outer shell frame 2012 fixed around the outer shell 2011. The base 11 can be fixed on the outer shell frame 2012, or it can be a part of the outer shell frame 2012 for installing the elastic structure 12.

[0057] The door inner shell 202 includes an inner shell 2021, an inner shell frame 2022 fixed around the inner shell 2021, and the fixing plate 134 is fixed on the inner shell 2021. The door inner shell 202 also includes an assembly plate 2023 arranged on the inner shell frame 2022, the assembly plate 2023 is spaced apart from the thermal insulation layer, the lateral dimension of the assembly plate 2023 is not greater than the distance between the two movable grooves 112, the base 11 is located at the upper part of the assembly plate 2023, the guide plate 125 extends to the lower part of the assembly plate 2023 through the movable groove 112, and when the top plate 121 moves relative to the base plate 111, the distance between the assembly plate 2023 and the thermal insulation layer provides space for the movement of the guide plate 125.

[0058] In this embodiment, the support plate 131 extends beyond the outer side of the housing 2011 , and the handle 135 is located on the outer side of the housing 2011 , so as to facilitate opening or closing the door.

[0059] Preferably, the elastic structure 12 is arranged higher than the door body to facilitate cooperation with the limiting protrusion 22 .

[0060] To sum up, the locking mechanism 100 of the utility model facilitates locking the first body 200 and the second body 300 through the cooperation of the fixing device 10 and the connecting device 20. At the same time, the elastic structure 12 in a squeezed state between the first body 200 and the second body 300 can improve the sealing of the first body 200 and the second body 300.
