Description

Technical Field

[0001] The present invention relates to the technical field of limiting structures, and particularly relates to a limiting structure and an installation and use method thereof. Background Art

[0002] More and more users prefer personalized refrigerators. For the same model of refrigerator, some like glass doors, some like color plate doors, and some like plastic doors; for the same type of door, different users often have widely different favorite patterns. This requires that in the case of not replacing the door body of the existing refrigerator, the panel can be replaced, so as to meet the needs of users for various patterns of glass doors, color plate doors and plastic doors.

[0003] For the existing door body, magnets are often pasted on the door panel, and the door panel is adhered to the door body through the adsorption force of the magnets. If some lighter door panels, relying solely on magnets can meet the needs of users, but for some glass panels or metal color plate panels, due to the relatively large self-weight of the panel, in order to overcome the self-weight of the panel, it is often necessary to greatly increase the number of magnets, which significantly increases the cost in this case. If screws or other methods are added, the effect of quickly disassembling and assembling the door panel cannot be achieved. Such problems trouble the manufacturers. Summary of the Invention

[0004] The purpose of the present invention is to provide a limiting structure and an installation and use method thereof, and solve the following technical problems:

[0005] How to quickly disassemble and assemble the relatively heavy refrigerator door panel.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A limiting structure is applied to the field of refrigerator door assembly, and includes a door body. A closing-connected lining board is arranged at the edge of the outer surface of the door body. A panel is detachably arranged inside the lining board. A connecting member is connected to one side edge of the panel close to the door body. The connecting member is L-shaped, and a slot is opened on the board of the connecting member away from the panel. A plurality of groups of limiting mechanisms corresponding to the connecting members one by one are arranged on the inner side of the lining board. The limiting mechanism includes a cylinder body with both ends being open. One end of the cylinder body is fixedly connected to the lining board, and the other end is provided with a wavy notch with a smooth transition between wave crests and wave troughs, and a groove is arranged on each wave crest. The number of wave crests and wave troughs of the wavy notch is even, and the wavy notch as a whole is a symmetrical structure;

[0008] Inside the cylinder body, an inner plate ring is connected. An insertion post is slidably inserted through the inner plate ring. One end of the insertion post away from the wavy notch is connected to a button, and the button is slidably inserted through the lining plate. The diameter of the button is larger than that of the insertion post and smaller than the inner diameter of the cylinder body. A spring sleeved on the insertion post is arranged between the button and the inner plate ring. A pin is vertically inserted through a column body of the insertion post near the wavy notch.

[0009] In a further scheme: The diameter of one end of the insertion post away from the button is smaller than the inner diameter of the slot on the connecting piece, and a chamfer is arranged at the edge of one end of the insertion post away from the button.

[0010] In a further scheme: The distances between the two ends of the pin and the wall surface of the insertion post are the same, and the diameter of the insertion post is smaller than the sizes of the grooves on the trough and the crest in the wavy notch.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-2As shown in the figure, the present invention is a limiting structure applied to the field of refrigerator door assembly, including a door body 100. A closing-connected lining plate 101 is arranged at the edge of the outer surface of the door body 100. The lining plate 101 is composed of four plates, and each plate is respectively arranged at the upper, lower, left, and right edges of the outer surface of the door body 100, and two adjacent plates are vertically connected, so that the lining plate 101 as a whole forms a square frame plate. A panel 200 is detachably arranged inside the lining plate 101. A connecting member 300 is connected to one side edge of the panel 200 close to the door body 100. The connecting member 300 is composed of two vertically connected plates, and the connecting member 300 is in an L shape. One of the plates in the connecting member 300 is connected to the panel 200, and a slot is opened on the other plate.

[0032] Please refer to Figure 3-7 As shown in the figure, a plurality of limiting mechanisms 400 corresponding to the connecting member 300 one by one are arranged inside the lining plate 101. The limiting mechanism 400 includes a cylinder body 401. A through hole is opened in the center of the cylinder body 401, and both ends are open. One end of the cylinder body 401 is fixedly connected to the lining plate 101, and a through hole is also opened at the connection between the lining plate 101 and the cylinder body 401, and this through hole is correspondingly communicated with the through hole of the cylinder body 401. The other end is provided with a wavy notch with a smooth transition between the wave crests and wave troughs, and a groove is arranged on each wave crest. The number of wave crests and wave troughs of the wavy notch is even, and the wavy notch as a whole is a symmetrical structure.

[0033] An inner plate ring 402 is connected inside the cylinder body 401. A plug post 403 is slidably penetrated inside the inner plate ring 402. One end of the plug post 403 away from the wavy notch is connected with a button 404. The button 404 is slidably penetrated through the through hole communicated with the lining plate 101 and the inner plate ring 402. The diameter of the button 404 is larger than the diameter of the plug post 403 and smaller than the inner diameter of the cylinder body 401. A spring 405 sleeved on the plug post 403 is arranged between the button 404 and the inner plate ring 402. A pin 407 is vertically penetrated through a column body of the plug post 403 close to the wavy notch, and the pin 407 is located in two opposite wave troughs or in the grooves on two opposite wave crests.

[0034] Specifically, the button 404 can extend to the outside of the lining plate 101 through the through hole on the lining plate 101 that communicates with the cylinder body 401, and the staff can press and rotate the button 404 here; when the panel 200 is not installed in the lining plate 101, the limiting mechanism 400 is in the unlocked state. At this time, the pin 407 lies horizontally in two opposite wave troughs, and the length of the spring 405 is the distance between the button 404 and the inner plate ring 402. The upper end of the button 404 extends to the outside of the lining plate 101, and the end of the plug post 403 away from the button 404, that is, the end does not exceed the end of the cylinder body 401 provided with the wavy notch; at this time, if the button 404 is pressed inward from the outside of the lining plate 101, the button 404 drives the plug post 403 to move accordingly, so that the end of the plug post 403 exceeds the end of the cylinder body 401 provided with the wavy notch. At this time, the pin 407 disengages from the two wave troughs, and then the button 404 is rotated to drive the plug post 403 to rotate. The plug post 403 drives the pin 407 to rotate, so that the pin 407 rotates into the groove on two opposite wave peaks. Release the button 404, and the position of the plug post 403 is locked.

[0035] Further, the diameter of the end of the plug post 403 away from the button 404 is smaller than the inner diameter of the slot on the connecting member 300, and a chamfer is provided at the edge of the end of the plug post 403 away from the button 404.

[0036] When assembling the panel 200 on the door body 100, first set the limiting mechanism 400 to the unlocked state, then install the panel 200 inside the lining plate 101, so that the plate on the connecting member 300 provided with the slot just corresponds to the limiting mechanism 400. At this time, the plug post 403 is aligned with the slot, and then the end of the plug post 403 is adjusted out through the above operation. Since the diameter of the end of the plug post 403 is smaller than the inner diameter of the slot, the end of the plug post 403 will enter the slot, thereby limiting the connecting member 300, and thus fixing the panel 200 on the door body 100.

[0037] Further, the distance between the two ends of the two pins 407 and the wall surface of the plug post 403 is the same, and the diameter of the plug post 403 is smaller than the size of the wave trough and the groove on the wave peak in the wavy notch; the length of the pin 407 is greater than the overall outer diameter of the wavy notch, which can ensure that the pin 407 can be stably arranged in the wave trough and the wave peak.

[0038] Further, a connection groove 406 is provided on the side of the button 404 away from the plug post 403, and a handle is installed in the connection groove 406; controlling the button 404 through the handle is more time-saving and labor-saving, and convenient and fast.

[0039] Further, the compression amount of the spring 405 is greater than the length of the wavy notch, which can ensure that the pin 407 can be transferred from the wave trough position to the wave peak position.

[0040] An installation and use method of the limit structure as described above, comprising the following steps:

[0041] S1: Fix a plurality of connectors 300 on the inner edge of the panel 200. One plate of the connector 300 is attached to the inner side of the panel 200, and the edge of the other plate is parallel to the edge of the panel 200;

[0042] S2: Install the limit mechanism 400 on the inner side of the lining plate 101, and the installation positions of the cylinders 401 correspond to the positions of the plurality of connectors 300 one by one. In the initial state, both ends of the pin 407 are located in the troughs of the wavy notches;

[0043] S3: Install the side of the panel 200 with the connectors 300 into the inner side of the lining plate 101, so that each connector 300 is aligned with the corresponding limit mechanism 400 respectively,

[0044] S4: Push the button 404 into the cylinder 401 through the handle. The button 404 drives the plug post 403 to move accordingly, and the plug post 403 drives the pin 407 to move accordingly until the lower end of the plug post 403 moves into the slot of the connector 300. At this time, the spring 405 disengages from the trough. Rotate the handle to drive the button 404 to rotate, and the button 404 drives the plug post 403 to rotate accordingly, so that the plug post 403 drives the pin 407 to move into the groove on the wave crest. At this time, the end of the plug post 403 is locked into the slot of the connector 300, that is, the panel 200 is fixed on the door body 100.
