DETAILED DESCRIPTION
[0027] 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.
[0028] 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 back of the refrigeration equipment is the back, the direction toward the ground is the bottom, and conversely, the direction away from the ground is the top. Other descriptions indicating directions are defined based on "upper" and "lower".
[0029] 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.
[0030] The utility model provides a refrigeration device, such as Figures 1 to 6 As shown, the refrigeration device includes a box body 10, a door body 20 covering the box body 10, and a lock hook assembly 30 arranged between the box body 10 and the door body 20, so as to lock the refrigeration device and prevent the door body 20 from being opened, so as to ensure the safety of the items in the refrigeration device. In the utility model, the thickness direction of the refrigeration device is the front-to-back direction, and the transverse direction of the refrigeration device is the left-to-right direction.
[0031] The box body 10 includes an outer shell and an inner container located in the outer shell, wherein the inner container forms a storage compartment.
[0032] The door 20 is pivotally connected to one side of the box 10 to open or close the storage compartment. Figure 4 and Figure 5 As shown, the door body 20 includes a door main body 21 and a door seal 22 fixed on the door main body 21 and extending toward one side of the box body 10. When the door body 20 closes the box body 10, the door seal 22 is used to seal between the box body 10 and the door body 20 to prevent the cold air in the storage room from leaking from the gap between the box body 10 and the door body 20, thereby avoiding energy waste.
[0033] The transverse end edge of the door seal 22 is located on the inner side of the door body 21 , that is, when the door body 20 closes the box body 10 , the door body 21 is at a certain distance from the box body 10 , so that a limiting space 23 is formed between the box body 10 , the door seal 22 and the door body 21 .
[0034] like Figure 1 and Figure 3 As shown, when the locking hook assembly 30 is provided with one, the refrigeration equipment also includes a locking structure 50 for connecting the box body 10 and the door body 20, and the locking hook assembly 30 and the locking structure 50 are respectively arranged at the upper part and the lower part of the box body 10 or the door body 20, that is, the locking hook assembly 30 and the locking structure 50 are respectively located on both sides of the center of the height direction of the refrigeration equipment. When the refrigeration equipment is relatively high, the locking hook assembly 30 and the locking structure 50 respectively lock the upper part and the lower part of the door body 20, increase the fixing points for locking the door body 20 and the box body 10, and can lock the door body 20 tightly to prevent the door body 20 from being opened by external force.
[0035] When two or more locking hook assemblies 30 are provided, the locking hook assemblies 30 are spaced between the box body 10 and the door body 20 along the height direction of the refrigeration equipment, so that multiple locking fixing points are provided between the door body 20 and the box body 10, which can lock the door body 20 tightly to prevent the door body 20 from being opened by external force.
[0036] The following is a detailed description taking the locking hook assembly 30 being located at the upper part of the refrigeration equipment as an example.
[0037] like Figures 1 to 4 As shown, the lock hook assembly 30 includes a lock hook 31, a lock hole 32 provided on the lock hook 31, a first fixing structure 33 provided on the box body 10 or the door body 21, and a second fixing structure 34 provided on the door body 21 or the box body 10. The lock hook 31 has a lock hook body 311, a first end 312 and a second end 314 at both ends of the lock hook body 311, the first end 312 is pivotally connected to the first fixing structure 33, and the second end 314 is movably engaged with the second fixing structure 34; the box body 10 and the door body 20 are in a closed state. When the lock hook 31 moves along the thickness direction of the refrigeration equipment, the second end 314 is engaged with the second fixed structure 34 to limit the lock hook 31 from moving toward the first fixed structure 33. At this time, the projection of the lock hole 32 along the horizontal direction of the refrigeration equipment is located in the limit space 23. When the lock ring 41 of the external lock 40 is locked at the lock hole 32, the lock ring 41 protrudes into the limit space 23. The lock ring 41 is limited in the limit space 23 along the front and rear direction to prevent the lock hook 31 from moving toward the first fixed structure 33, so as to achieve the purpose of locking the door body 20 and the box body 10 together.
[0038] The first fixing structure 33 is provided on the door body 21, and the second fixing structure 34 is provided on the box body 10. After the lock hook 31 moves backward, the second end 314 is engaged with the second fixing structure 34 to prevent the lock hook 31 from continuing to move toward the second fixing structure 34. Of course, the first fixing structure 33 is provided on the box body 10, and the second fixing structure 34 is provided on the door body 20. The design of the lock hook 31 and the cooperation between the lock hook 31 and the first fixing structure 33 and the second fixing structure 34 are the same, and are also within the protection scope of the present application.
[0039] Furthermore, the width of the first end 312 is greater than the width in the middle of the lock hook body 311, and the lock hook 31 also includes a pivot slot 315 provided at the first end 312, and the first fixed structure 33 is pivotally connected to the pivot slot 315. When the lock hook 31 is moved, the pivot slot 315 moves relative to the first fixed structure 33 toward the second fixed structure 34. When the door body 20 is not locked on the box body 10, the first fixed structure 33 is used to fix the lock hook 31 to prevent the lock hook 31 from being lost when locking the door.
[0040] Preferably, the front-to-back length of the pivot slot 315 is not less than the length of the limiting space 23 , so as to avoid limiting the moving range of the locking hook 31 when the locking hook 31 is moved.
[0041] In this embodiment, the ends of the pivot slot 315 along the front-to-back direction are both arc-shaped, and when the first fixing structure 33 moves to the end of the pivot slot 315 , it just matches the shape of the first fixing structure 33 .
[0042] Furthermore, the locking hook 31 further includes a limiting structure 313 disposed at the second end 314 of the locking hook body 311 , and the limiting structure 313 is engaged with the second fixing structure 34 .
[0043] like Figure 2 and Figure 4 As shown, the limiting structure 313 includes a clamping arm 3131 connected to the locking hook body 311, and a limiting arm 3132 connected to the clamping arm 3131 and extending toward the second end 314. The clamping arm 3131, the limiting arm 3132 and the locking hook body 311 form a limiting groove 3133 that is clamped with the second fixing structure 34. When the locking hook 31 cooperates with the second fixing structure 34, the second fixing structure 34 is located in the limiting groove 3133.
[0044] It is understandable that the limiting structure 313 can be fixed to the upper side of the lock hook body 311, or to the lower side of the lock hook body 311, and the cooperation between the second fixing structure 34 and the limiting groove 3133 will not be affected. In this embodiment, the limiting structure 313 is preferably fixed to the lower side of the lock hook body 311, and when the second fixing structure 34 and the limiting structure 313 cooperate with each other, the lock hook body 311 is supported on the second fixing structure 34, and the second fixing structure 34 will not fall off from the edge of the lock hook body 311, thereby improving the overall structural strength of the lock hook assembly 30.
[0045] When installing the locking hook 31, the first end 312 of the locking hook 31 is rotated relative to the first fixed structure 33 until the second end 314 bypasses the second fixed structure 34, so that the second fixed structure 34 is located at the opening of the limiting groove 3133, and then the locking hook 31 is moved backward so that the second fixed structure 34 is engaged with the limiting groove 3133. In order for the second fixed structure 34 to smoothly enter the limiting groove 3133, the end of the limiting arm 3132 has an arc-shaped guide surface.
[0046] Preferably, the length of the limiting groove 3133 along the front-to-back direction is not less than the length of the limiting space 23, that is, the length of the limiting groove 3133 is greater than or equal to the length of the limiting space 23. In the process of the external lock 40 driving the lock hook 31 to move along the front-to-back direction, the lock hook 31 will not fall off relative to the second fixed structure 34, that is, the lock hook 31 is limited in the range between the second fixed structure 34 and the limiting space 23 along the front-to-back direction. Under the premise that the external lock 40 locks the lock hook 31, the door body 20 will not be opened.
[0047] Preferably, the limiting groove 3133 and the pivot groove 315 extend in the same direction and on the same horizontal line, so that the locking hook 31 is horizontally arranged for easy operation, and the locking hook 31 will not be unevenly stressed due to tilting, thereby preventing the second fixing structure 34 from detaching from the limiting groove 3133.
[0048] Furthermore, if Figure 4 As shown, the first fixing structure 33 and the second fixing structure 34 both include a fixing column 331 fixed to the box body 10 or the door body 21, and a stop portion 332 located at the end of the fixing column 331, the radius of the stop portion 332 is greater than the radius of the fixing column 331, the fixing column 331 is located in the limiting groove 3133 or the pivot groove 315, the radius of the stop portion 332 is greater than the width of the limiting groove 3133 or the pivot groove 315, so as to prevent the fixing column 331 from falling off from the limiting groove 3133 or the pivot groove 315.
[0049] Furthermore, the length of the fixing column 331 is consistent with the thickness of the locking hook body 311, so that the locking hook 311 is tightly attached to the side walls of the box body 10 and the door body 21, and the locking hook 31 and the box body 10, the door body 21 and the door seal 22 form a closed limiting space 23 that limits the locking ring 41 to lock the door body 20 on the box body 10.
[0050] Preferably, the first fixing structure 33 and the second fixing structure 34 are at the same height to facilitate the operation of the locking hook 31. At the same time, the locking hook 31 is horizontal along the front-to-back direction, and the locking hook 31 will not be subjected to uneven force due to tilting, thereby preventing the second fixing structure 34 from detaching from the limiting groove 3133.
[0051] Of course, in the embodiment where the pivot slot 315 and the limiting slot 3133 are not at the same horizontal position, the relative height of the first fixing structure 33 and the second fixing structure 34 can be adaptively adjusted, which is also within the protection scope of this embodiment.
[0052] To summarize, the refrigeration equipment of the present invention is provided with a lock hook assembly 30. When the second end 314 of the lock hook 31 and the second fixed structure 34 are in a mutually engaged state, the lock hole 32 is just located in the limiting space 23 between the cabinet 10 and the door body 20. The user uses the lock ring 41 of the external lock 40 to lock the lock hole 32, and the lock ring 41 protrudes into the limiting space 23. At this time, the lock hook 31 is limited between the first fixed structure 33 and the limiting space 23 and will not fall off, thereby locking the cabinet 10 and the door body 20 to prevent the door body 20 from being directly opened.
[0053] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative method 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 embodiment may also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0054] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the utility model and are not intended to limit the protection scope of the utility model. Any equivalent embodiments 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.
