Description

Technical Field

[0001] The present application relates to the field of furniture and manufacturing technology, and in particular to a cabinet. Background Art

[0002] Traditional custom cabinets are usually divided into upper and lower cabinets when making super-high cabinets (cabinet height exceeds 2400 mm). When users look for things, they have to search through the cabinet doors one by one, which is troublesome. The design of super-high cabinets mostly uses vertical lines, which visually increases the height and makes the space feel more spacious and transparent. Therefore, super-high cabinets are the current mainstream design trend.

[0003] However, the problem with super-tall cabinets is that they are inconvenient to install. Currently, super-tall cabinets are usually assembled by installing the cabinet body in a side-lying manner and then standing it up. The cabinet body as a whole is relatively heavy, which is very inconvenient to stand up. In addition, a certain amount of space needs to be reserved between the ceiling and the top surface of the cabinet body when standing it up. Therefore, the current super-tall cabinets are usually designed as two sets of upper and lower cabinets, with only the door panels being integrated to the top. The traces of splicing can be clearly seen on the side of the cabinet body, and the appearance of the side of the cabinet body is limited.

[0004] In addition, the problem with current cabinets is that the back panel is usually snapped into grooves on the side panels, top panel and bottom panel, and there is no fixed connection between the back panel and these panels, which does not contribute to the overall strength of the cabinet.

[0044] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0045] See also Figure 1 , Figure 3 , Figure 4 As shown, the embodiment of the present application provides a cabinet 100, which includes a side panel 1, a back panel 2, a first connecting member and a second connecting member, wherein the side panel 1 is an integral structure, the back panel 2 includes an upper back panel 21 and a lower back panel 22 that are spliced ​​together, the left and right sides of the upper back panel 21 are detachably and fixedly connected to the side panel 1 through the first connecting member, the upper end surface of the lower back panel 22 is provided with a first connecting hole 221, the rear surface of the lower back panel 22 is provided with a first locking hole 221 connected to the first connecting hole 221 thereof, and the lower end surface of the upper back panel 21 is correspondingly provided with a second connecting hole 211 , and the rear surface of the upper back plate 21 is provided with a second locking hole 212 connected to the second connecting hole 211, the second connecting member includes a first double-headed connecting rod 61 and two first eccentric wheels 62, one end (lower end) of the first double-headed connecting rod 61 is arranged in the first connecting hole 221, a first eccentric wheel 62 is arranged in the first locking hole 221 and locks the lower end of the first double-headed connecting rod 61, the other end (upper end) of the first double-headed connecting rod 61 is arranged in the second connecting hole 211, and is locked by the first eccentric wheel 62 arranged in the second locking hole 212.

[0046] The side panels 1 mentioned above can be two and spaced apart, and the back panel 2 is disposed between the two side panels 1; in other optional embodiments, the side panel 1 can be one, and the other side can be replaced by an existing fixed surface such as a wall or other cabinet panels. In the following description, the solution of sandwiching the back panel 2 between two side panels 1 is taken as an example for explanation.

[0047] When installing the cabinet 100, especially when the cabinet 100 is an extra-high cabinet, it is not necessary to pre-assemble the back panel 2 and the side panel 1 in a side-lying position. Instead, the side panel 1 of the integral structure can be directly placed upright, and the upper back panel 21 can be placed between the two side panels 1. The left and right sides of the upper back panel 21 are fixed to the side panels 1 by a first connecting piece. At this time, the upper back panel 21 and the two side panels 1 generally form a semi-enclosed fixed structure. Then, one end of the first double-headed connecting rod 61 is installed in the first connecting hole 221 on the upper end face of the lower back panel 22, and the lower back panel 22 is tilted at a certain angle. The installer is located in front of the back panel 2 and inserts the other end of the first double-headed connecting rod 61 upward into the second connecting hole 211 on the lower end face of the upper back panel 21. At this time, the lower back panel 22 is tilted relative to the upper back panel 21 (see Fig. 9 As shown), push the lower back plate 22 from front to back ( Fig. 9 The lower back plate 22 is rotated until it is in a vertical state (see Figure 2 and Fig. 9 Then, the two first eccentric wheels 62 are respectively placed in the first locking hole 221 and the second locking hole 212, and both ends of the first double-headed connecting rod 61 are locked to achieve vertical splicing of the upper back plate 21 and the lower back plate 22.

[0048] During the above assembly process, first, the cabinet body 100 as a whole does not need to be assembled on its side first, which saves the flipping process, saves time and effort, and in this way, the side panel 1 can be made into a single board from top to bottom without any splicing; second, no space needs to be reserved between the ceiling and the cabinet body 100, and a seamless installation with the ceiling can be achieved; third, the upper back panel 21 and the side panel 1 are fixedly connected by a first connecting piece, which can enhance the overall assembly strength of the cabinet body 100; fourth, at least no grooves are required on the side panel 1, which reduces the processing steps of the side panel 1 and reduces the production cost. Only holes need to be reserved on the side panel 1 (holes for installing the first connecting piece, which will be described in detail below), which also ensures the strength of the side panel 1; fifth, the first connecting piece and the second connecting piece are both existing connection structures, which will not increase the material design cost.

[0049] Here, the directional words used in the above description and the following description are explained: In this application, six directions, namely "up", "down", "left", "right", "front", and "back", are defined. These directions are all defined based on the user's direction when the user is using and facing the cabinet 100. For example, "left" corresponds to the user's left hand side, and the others are similar. Please refer to the detailed description. Figures 1 to 9As shown. The "top", "bottom", "back" and "front" used below correspond to "upper", "lower", "back" and "front" respectively. In addition, the "inside" and "outside" used in the following description are based on the space enclosed by the side panel 1 and the back panel 2.

[0050] Typically, the cabinet 100 further includes a top plate 3 and / or a bottom plate 4, wherein the top plate 3 is mounted between the top ends of the two side plates 1, and the bottom plate 4 is mounted between the bottom ends of the two side plates 1. Of course, a door plate (not shown) connected to the front end of the side plates 1 may also be included.

[0051] The cabinet 100 may be a wardrobe, a shoe cabinet, a cupboard, a storage cabinet, or a combination cabinet having multiple functions, etc., without any particular limitation.

[0052] There is no specific limitation on the height of the upper back plate 21 and the lower back plate 22. The height of the upper back plate 21 may be greater than the height of the lower back plate 22, or equal to the height of the lower back plate 22, or less than the height of the lower back plate 22.

[0053] In one embodiment, the height of the lower back plate 22 is greater than that of the upper back plate 21. The purpose of this design is that the bottom end of the lower back plate 22 can be supported on the ground or the bottom plate 4, and the upper back plate 21 will be supported and fixed by the lower back plate 22 and the side plate 1. On this basis, the lower height of the upper back plate 21 will help reduce its force on the side plate 1, thereby ensuring the installation stability of the upper back plate 21.

[0054] It should be noted that in the prior art, the side panel 1 is usually an 18 mm standard panel, and its strength can be designed to be ultra-high, that is, the side panel 1 of the integral structure can be more than 2.4 meters, and the overall height of the cabinet 100 can be more than 2.4 meters.

[0055] In this embodiment, in order to open the above-mentioned first connection hole 221 and the second connection hole 211 on the end surfaces of the upper back plate 21 and the lower back plate 22 that are spliced ​​to each other, the upper back plate 21 and the lower back plate 22 need to have sufficient thickness. The back plate in the prior art is usually a 9 mm thin plate, which can only be designed to be 2.4 meters at most. For the cabinet 100 with an ultra-high height, the 9 mm thin plate cannot meet its performance requirements. Therefore, in this embodiment, the thickness of the upper back plate 21 and the lower back plate 22 is greater than 9 mm. In an optional embodiment, the upper back plate 21 and the lower back plate 22 are 18 mm standard plates.

[0056] The 18 mm standard board can be designed as an extra-high board, for example, the height of the lower back board 22 is greater than 2.4 meters.

[0057] In this way, by using an upper back panel 21 and a lower back panel 22 with a thickness greater than 9 mm, the design requirements of the first connecting hole 221 and the second connecting hole 211 can be met, and the overall strength of the back panel 2 and the cabinet 100 is also improved; in addition, when the back panel 2 and the side panel 1 are of the same model, the back panel 2 and the side panel 1 can also be ensured to be the same color, thereby reducing the color difference between different parts of the cabinet 100 and ensuring consistency in appearance.

[0058] In order to ensure the connection strength between the upper back plate 21 and the lower back plate 22, in one embodiment, the number of the second connecting members is multiple and they are spaced apart along the length direction of the seam between the upper back plate 21 and the lower back plate 22 (i.e., the left-right direction). Figure 3 shown.

[0059] The number of the second connectors is not limited and can be determined according to the width (left-right dimension) of the upper back plate 21 and the lower back plate 22. For example, the distance between two adjacent second connectors can be 10 cm to 30 cm, or the distance between two adjacent second connectors can be in other ranges, which is not particularly limited here.

[0060] See also Figure 3 and Figure 5 As shown, in one embodiment, the cabinet 100 further includes an angle bracket 7, which is planar, with an upper end connected to the upper back plate 21 and a lower end connected to the lower back plate 22. The angle bracket 7 can further enhance the connection strength between the upper back plate 21 and the lower back plate 22, thereby ensuring the strength of the upper back plate 21, the lower back plate 22 and the cabinet 100.

[0061] The installation of the angle code 7 can be implemented after the first eccentric wheel 62 is locked.

[0062] The corner code 7 can be arranged on the back of the upper back plate 21 and the lower back plate 22, that is, when the user faces the cabinet 100, the corner code 7 is not visible. In this way, the appearance consistency of the cabinet 100 can be further achieved.

[0063] For further information, see Figure 5 As shown, corner code grooves 20 are formed on the back side of the upper back panel 21 and the back side of the lower back panel 22, and corner code 7 is arranged in the corner code groove 20. Optionally, the plane of corner code 7 is kept flush with the back side of the upper back panel 21 and the back side of the lower back panel 22 so as not to affect the situation where the back panel 2 needs to be placed against the wall.

[0064] Of course, it is understandable that in more embodiments, according to actual needs, the corner code 7 can also be connected to the front of the upper back plate 21 and the lower back plate 22, and the corner code groove 20 also forms the front of the upper back plate 21 and the lower back plate 22.

[0065] Please continue reading Figure 3As shown, in an optional embodiment, the number of angle codes 7 is multiple and they are spaced apart along the left-right direction.

[0066] The number of the corner codes 7 is not limited, and can be determined according to the width of the upper back plate 21 and the lower back plate 22, the number of the second connecting members, etc. For example, the distance between two adjacent corner codes 7 can be 10 cm to 30 cm, or the distance between two adjacent corner codes 7 can be in other ranges, which is not particularly limited here.

[0067] Optionally, when the number of the second connecting members and the number of the angle codes 7 are both plural, the angle codes 7 and the second connecting members may be distributed alternately.

[0068] Next, see Figure 6 As shown, the first connecting member includes a second double-headed connecting rod 91 and a second eccentric wheel 92, a third connecting hole 11 is provided on the inner surface of the side plate 1, fourth connecting holes 213 are provided on the left and right sides of the upper back plate 21, and a third locking hole 214 connected to the fourth connecting hole 213 is provided on the rear surface of the upper back plate 21, one end of the second double-headed connecting rod is fixedly installed in the third connecting hole 11, and the other end of the second double-headed connecting rod is provided in the fourth connecting hole 213 and is locked by the second eccentric wheel provided in the third locking hole 214.

[0069] One end of the second double-ended connecting rod 91 located inside the side plate 1 may be a threaded head.

[0070] Since there is no connection between the two side panels 1 when installing the upper back panel 21, the distance between the two side panels 1 can be adjusted. Therefore, the above-mentioned first connecting member can be replaced by other forms of connecting members. For example, the first connecting member is a wooden tip or a metal or plastic columnar structure similar to a wooden tip. At this time, a third connecting hole 11 is provided on the inner surface of the back panel 2, and a fourth connecting hole 213 is correspondingly provided on the left and right sides of the upper back panel 21. The two ends of the columnar structure can be respectively inserted into the third connecting hole 11 and the fourth connecting hole 213.

[0071] In more embodiments, the first connecting member can be replaced by more other forms, which are not listed one by one and are not specifically limited here.

[0072] See also Figure 2 , Figure 7 and Figure 8As shown, a third connecting member is also installed on the side panel 1 of the cabinet 100, and the third connecting member includes a fixing member 81, a locking member 82 and a snap member 83. One side of the fixing member 81 is fixed to the inner surface of the side panel 1, and the locking member 82 (such as a screw) passes through the fixing member 81 and hits the inside of the side panel 1, thereby fixing the fixing member 81 to the inner surface of the side panel 1; a mushroom-head-style protrusion 810 is provided on the fixing member 81, and a card slot 830 adapted to the shape of the protrusion 810 is provided at the lower end of the snap member 83, and corresponding installation slots (not shown) are formed on the left and right sides of the lower back panel 22, and the snap member 83 is installed in the installation slot. When according to Fig. 9 As shown, when the lower back plate 22 is rotated from front to back, the locking groove 830 of the locking member 83 in the installation groove passes over the protruding buckle 810 and then locks into the protruding buckle 810, so that the lower back plate 22 and the side plate 1 are fixedly connected.

[0073] On the side of the lower back plate 22 , one or more third connecting members may be provided according to the height of the lower back plate 22 , for example, multiple third connecting members may be spaced apart and distributed up and down.

[0074] See also Figure 1 and Figure 2 As shown, the cabinet 100 further includes a movable layer board 5, the left and right sides of which are mounted to the inner surface of the side board 1 through a layer support (not shown), and the movable layer board 5 can cover the joint gap between the upper back board 21 and the lower back board 22. In this way, the joint marks between the upper back board 21 and the lower back board 22 seen from the front can be further avoided, especially when the corner bracket 7 is located at the back, there can be no joint marks between the upper back board 21 and the lower back board 22.

[0075] The installation of the movable layer plate 5 can be performed after the first eccentric wheel 62 is locked, or after the third connecting member is locked.

[0076] The support piece can be fixed on the side panel 1 and is designed to protrude relative to the inner surface of the side panel 1. A slot is provided on the lower surface of the movable layer board 5. The movable layer board 5 is moved from top to bottom until the support piece is inserted into the slot (not shown), thereby limiting the downward movement of the movable layer board 5, so that the movable layer board 5 is stably supported at the required height and allows the movable layer board 5 to be detachable.

[0077] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
