Description

Technical Field

[0001] The invention relates to a cabinet, in particular to a household storage cabinet. Background Art

[0002] Existing household cabinets are generally double-door cabinets. Due to the influence of the hinge structure, the double doors of existing double-door cabinets cannot be fully opened, that is, the opening angle is less than 180°; therefore, when the double doors are applied to the cabinet door, the entire cabinet body cannot be exposed, resulting in insufficient space for users to conveniently organize items in the cabinet. Moreover, after the existing door structure is unfolded, it also needs to occupy a large space, which not only limits the application scenarios of the door structure (or cabinet body), but also is not conducive to user operation, resulting in the user often being interfered by the cabinet door when organizing items in the cabinet, affecting efficiency.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0035] like Figure 1-3 As shown, a storage cabinet comprises a bottom plate 8, a top plate 7, a rear panel and a pair of side panels 9 which are assembled and fixed to each other, the storage cabinet further comprises a front panel, the front panel is movably arranged between the pair of side panels 9 and symmetrically arranged with the rear panel, the edges of the top plate 7 and the bottom plate 8 are respectively provided with rails 71, and the front panel slides on the rails 71;

[0036] The side panel 9 includes an inner panel 749 and an outer panel 759, a gap is provided between the inner panel 749 and the outer panel 759, and the front panel slides on the track 71 and is folded and placed in the gap. When the storage cabinet is in an open state, the front panel (cabinet door, which is hinged by the first door panel, the second door panel and the third door panel) is in a folded state and slides along the track 71 to the position of the side panel 9, parallel to the side panel 9, so that the cabinet door has the largest opening and does not occupy additional space, and the user will not be interfered by the cabinet door during the sorting process, which is more convenient to use.

[0037] When the storage cabinet is in a closed state, the front panel is in an open state, and forms a closed cabinet body along the track 71 with the side panels 9, the bottom panel 8, the top panel 7 and the rear panel.

[0038] The track 71 is respectively fixed on the top plate 7 and the bottom plate 8 and placed between the outer plate 759 and the inner plate 749. The top and bottom of the front panel are provided with pulley sets, which are engaged on the track 71 and drive the front panel to slide along the track 71.

[0039] The pulley group includes a first pulley 72 and a second pulley 73, and the first pulley 72 and the second pulley 73 are connected by a steering assembly. When the first pulley 72 rolls to the corner of the track 71, the steering assembly drives the second pulley 73 to turn along the track 71 to roll in a direction perpendicular to the rolling direction of the first pulley 72.

[0040] The front panel comprises a first door panel, a second door panel and a third door panel, the second door panel is located between the first door panel and the third door panel, and the first door panel and the second door panel as well as the third door panel and the second door panel are movably connected via hinges;

[0041] The hinge drives the first door panel and the third door panel to rotate relative to the second door panel and move closer to each other, or the hinge drives the first door panel and the third door panel to rotate relative to the second door panel and move away from each other, and makes the first door panel, the second door panel, and the third door panel coplanar.

[0042] When the first door panel, the second door panel, and the third door panel are coplanar, the storage cabinet forms a closed cabinet body, and when the first door panel and the third door panel are rotated relative to the second door panel and approach each other, the first door panel, the second door panel, and the third door panel are folded and placed in the gap, the width of the first door panel is greater than the width of the second door panel and is equal to the width of the third door panel, and the width of the first door panel, the third door panel, and the side panel 9 are equal.

[0043] like Figure 4 It is a schematic diagram of a hinge structure, comprising a fixed seat 1, a left rotating seat 2, and a right rotating seat 3.

[0044] The fixing seat 1 is provided with a receiving groove 11, and the fixing seat 1 is provided with a first hinge column 12 and a second hinge column 13. The first hinge column 12 and the second hinge column 13 are both located in the receiving groove 11, and the first hinge column 12 and the second hinge column 13 are parallel to each other and spaced a certain distance apart. It can be understood that the first side of the left rotating seat 2 is located in the receiving groove 11, and the first side of the right rotating seat 3 is located in the receiving groove 11, which can make the hinge structure more compact and reduce the space occupied by the hinge as a whole. In addition, the receiving groove 11 can also protect the connection between the first side of the left rotating seat 2 and the first hinge column 12; similarly, the receiving groove 11 can also protect the connection between the first side of the right rotating seat 3 and the second hinge column 13.

[0045] The first side of the left rotating seat 2 is pivotally connected to the first hinge column 12, and the second side of the left rotating seat 2 is arranged opposite to the first side of the left rotating seat 2, and the second side of the left rotating seat 2 is located outside the receiving groove 11. It can be understood that by arranging the second side of the left rotating seat 2 outside the receiving groove 11, it is ensured that the second side of the left rotating seat 2 is normally connected to the door structure.

[0046] The first side of the right rotating seat 3 is pivotally connected to the second hinge column 13, and the second side of the right rotating seat 3 is arranged opposite to the first side of the right rotating seat 3, and the second side of the right rotating seat 3 is located outside the receiving groove 11. It can be understood that by arranging the second side of the right rotating seat 3 outside the receiving groove 11, it is ensured that the second side of the right rotating seat 3 is normally connected to the door structure.

[0047] Since the second side of the left rotating seat 2 can rotate in an arc around the first side of the left rotating seat 2 (or the first hinge column 12), the second side of the right rotating seat 3 can rotate in an arc around the first side of the right rotating seat 3 (or the second hinge column 13). Therefore, the second side of the left rotating seat 2 and the second side of the right rotating seat 3 can move closer to each other or away from each other.

[0048] The hinge further includes a linkage assembly, which includes a first rotating rod 41 , a second rotating rod 42 , and a third rotating rod 43 .

[0049] The first end of the first rotating rod 41 is pivotally connected to the fixed seat 1, and the second end of the first rotating rod 41 is pivotally connected to the second rotating rod 42. The first end of the second rotating rod 42 is pivotally connected to the left rotating seat 2, the first end of the third rotating rod 43 is pivotally connected to the right rotating seat 3, and the second end of the second rotating rod 42 is pivotally connected to the second end of the third rotating rod 43. Among them, the pivot position of the first rotating rod 41 and the second rotating rod 42 can be located at any position of the second rotating rod 42, and in this embodiment, the pivot position of the first rotating rod 41 and the second rotating rod 42 is located between the first end of the second rotating rod 42 and the second end of the second rotating rod 42, and the distance between the first rotating rod 41 and the first end of the second rotating rod 42 is smaller than the distance between the first rotating rod 41 and the second end of the second rotating rod 42. Such a setting is conducive to a better linkage effect among the first rotating rod 41, the second rotating rod 42, and the third rotating rod 43.

[0050] It should be noted here that the pivot connection method in this embodiment can be connected through a pin shaft; it can also be connected through a bolt and a nut (that is, not completely locked); it can also be that one of the components itself forms a cylinder and is movably connected to the hole of the other component; since the pivot connection methods are too numerous to enumerate, they will not be described in detail in this embodiment.

[0051] like Figure 4-7 , the left rotating seat 2, the fixed seat 1, the right rotating seat 3 and the three door panels are fixedly connected respectively, when the second side of the left rotating seat 2 and the second side of the right rotating seat 3 can be moved closer to each other or away from each other, the door panel fixed to the left rotating seat 2 and the door panel fixed to the right rotating seat 3 can be moved closer to each other or away from each other. When the two door panels are close to each other, they are in a folded state, that is, the cabinet door of the storage cabinet is in a fully open state, which is very convenient for the user to organize the items in the cabinet. Moreover, after the three door panels are folded and merged into one door panel and stored in the gap of the side panel 9, the cabinet door is equivalent to a fully open state, which is very convenient for the user to organize the items in the cabinet; it also makes the window door and cabinet door installed with the hinge suitable for use in more narrow spaces, with little interference to the user's range of activities, and more convenient to use.

[0052] Obviously, to sum up, the hinge of the present invention is pivotally connected to the first hinge column 12 through the first side of the left rotating seat 2, and the first side of the right rotating seat 3 is pivotally connected to the second hinge column 13, so that the second side of the left rotating seat 2 can make a circular rotation around the first side of the left rotating seat 2, and the second side of the right rotating seat 3 can make a circular rotation around the first side of the right rotating seat 3; thereby achieving the second side of the left rotating seat 2 and the second side of the right rotating seat 3 can move closer to or away from each other. When the left rotating seat 2, the fixed seat 1, and the right rotating seat 3 are fixedly connected to the three door panels respectively, the door panels fixed to the left rotating seat 2 and the door panels fixed to the right rotating seat 3 can be moved closer to or away from each other; and further, when the door panels fixed to the left rotating seat 2 and the door panels fixed to the right rotating seat 3 are close to each other, the three door panels moving closer to each other is equivalent to occupying the space of only one door panel, so that the entire door structure occupies a small space, and the three door panels can be folded and merged into one door panel and then stored in the gap between the side panels 9, and the cabinet door is equivalent to a fully open state, which is very convenient for the user to organize the items in the cabinet; it also makes the window doors and cabinet doors installed with the hinge suitable for use in more narrow spaces, with little interference with the user's range of activities, and more convenient to use.

[0053] Furthermore, by pivoting the first end of the first rotating rod 41 to the fixed seat 1, the first end of the first rotating rod 41 serves as a supporting element and a travel limit element for supporting the left rotating seat 2 and the right rotating seat 3, thereby limiting the range of motion of the left rotating seat 2 and the right rotating seat 3. The second end of the first rotating rod 41 performs an arc rotation around the first end of the rotating rod, and cooperates with the first side of the left rotating seat 2 to pivotally connect to the first hinge column 12, and the first side of the right rotating seat 3 to pivotally connect to the second hinge column 13; so as to ensure that the left rotating seat 2 and the right rotating seat 3 can repeatedly move closer to or farther from each other.

[0054] Since the second end of the first rotating rod 41 is pivotally connected to the second rotating rod 42, the first end of the second rotating rod 42 is pivotally connected to the left rotating seat 2, the first end of the third rotating rod 43 is pivotally connected to the right rotating seat 3, and the second end of the second rotating rod 42 is pivotally connected to the second end of the third rotating rod 43. Therefore, the left rotating seat 2 and the right rotating seat 3 are in a synchronous motion state, that is, as long as the left rotating seat 2 is pulled, the right rotating seat 3 naturally performs a mirror motion under the linkage effect, which is very convenient to use.

[0055] Preferably, the hinge may further include a first torsion spring 51 and a second torsion spring 52, wherein the first torsion spring 51 is sleeved on the first hinge column 12, and the two ends of the first torsion spring 51 are respectively fixed to the fixed seat 1 and the left rotating seat 2. The second torsion spring 52 is sleeved on the second hinge column 13, and the two ends of the second torsion spring 52 are respectively fixed to the fixed seat 1 and the right rotating seat 3. It can be understood that the impact force is buffered by the first torsion spring 51 and the second torsion spring 52, so that the second side of the left rotating seat 2 and the second side of the right rotating seat 3 can be elastically buffered when they are close to each other, thereby preventing the left rotating seat 2 and the right rotating seat 3 from causing a strong rigid impact on the fixed seat 1, especially after being installed on the door structure, it can prevent the impact between the door panels. Moreover, the first torsion spring 51 and the second torsion spring 52 can also provide elastic force to make it easier for the second side of the left rotating seat 2 and the second side of the right rotating seat 3 to move away from each other, so that when the hinge is applied to the door structure, it is easier to pull the door panel and close the door panel.

[0056] Preferably, the fixing seat 1 is provided with a first hinge hole (not shown in the figure) and a second hinge hole (not shown in the figure), and the first hinge hole and the second hinge hole are respectively movably connected to the first hinge column 12 and the second hinge column 13; such a setting can make the first hinge column 12 and the second hinge column 13 rotate, thereby avoiding the first torsion spring 51 and the first hinge column 12 from getting stuck, or the second torsion spring 52 and the second hinge column 13 from getting stuck, which may cause the first torsion spring 51 or the second torsion spring 52 to be damaged. In addition, the first hinge column 12 and the second hinge column 13 can rotate after long-term use, and will not be excessively worn due to local long-term bearing of the main load. It should be noted here that, in addition to this setting, the first hinge column 12 and the second hinge column 13 can be fixed on the fixing seat 1, for example, by welding, bonding, riveting, bolting, etc.

[0057] More preferably, the bottom wall of the receiving groove 11 of the fixing seat 1 protrudes into the groove of the receiving groove 11 to form a rib plate 14, and the first hinge hole and the second hinge hole are both provided on the rib plate 14. It can be understood that there are two first hinge holes and two second hinge holes. The two ends of the first hinge column 12 are respectively inserted into the two first hinge holes, and the two ends of the second hinge column 13 are respectively inserted into the two second hinge holes. This arrangement avoids using the side wall of the receiving groove 11 to support the first hinge column 12 and the second hinge column 13, so that the receiving groove 11 has more space left to accommodate other components, so that the space occupied by the hinge is smaller; it also allows more components of the hinge to be accommodated in the receiving groove 11, so as to be protected by the side wall of the receiving groove 11 to avoid scratches and damage.

[0058] Preferably, the linkage assembly is located in the receiving groove 11, and the first rotating rod 41 is pivotally connected to the first side wall 111 of the receiving groove, so that the connection between the first rotating rod 41 and the fixed seat 1 is located in a hidden position, and the connection between the fixed seat 1 and the first rotating member has greater strength. Furthermore, two linkage assemblies are provided, and the two linkage assemblies are respectively located on the opposite sides of the left rotating seat 2. And the first hinge hole and the second hinge hole are both located between the two linkage assemblies. Such a configuration is conducive to strengthening the supporting strength of the fixed seat 1 to the left rotating seat 2 and the right rotating seat 3, and also makes the structure of the hinge more compact, making the space utilization of the receiving groove 11 more reasonable.

[0059] In order to make the left rotating seat 2 and the right rotating seat 3 fully unfolded (that is, when the left rotating seat 2 and the right rotating seat 3 are away from each other), the left rotating seat 2, the fixed seat 1, and the right rotating seat 3 all have an end surface located in the same plane to ensure that when the hinge is applied to the cabinet door, the door panels can be flush when closed. Preferably, one of the left rotating seat 2 and the second side wall 112 of the receiving groove is provided with a first clearance groove 1121, and the first clearance groove 1121 is used to accommodate the left rotating seat 2 or the second side wall 112 of the receiving groove; that is, when the first clearance groove 1121 is provided on the left rotating seat 2, the first clearance groove 1121 is used to accommodate the second side wall 112 of the receiving groove; when the first clearance groove 1121 is provided on the second side wall 112 of the receiving groove, the first clearance groove 1121 is used to accommodate the left rotating seat 2. One of the right rotating seat 3 and the third side wall 113 of the receiving groove is provided with a second clearance groove 1131, and the second clearance groove 1131 is used to accommodate the right rotating seat 3 or the third side wall 113 of the receiving groove. Obviously, the second side wall 112 of the receiving groove is arranged opposite to the third side wall 113 of the receiving groove. It should be further explained here that it can be understood that in addition to this setting method, the first clearance groove 1121 may not be set, and it is only necessary to bend the structure of the left rotating seat 2 and the right rotating seat 3 at a certain angle to prevent them from interfering with the second side wall 112 of the receiving groove and the third side wall 113 of the receiving groove. At this time, the left rotating seat 2, the fixed seat 1, and the right rotating seat 3 do not have an end face that is located in the same plane, so that the entire storage cabinet is in a closed state.

[0060] like Figure 4-7As shown, the first door panel 61, the second door panel 62, and the third door panel 63. The second door panel 62 is located between the first door panel 61 and the third door panel 63. The fixed seat 1 is fixedly connected to the second door panel 62, and the second side of the left rotating seat 2 and the second side of the right rotating seat 3 are respectively fixedly connected to the first door panel 61 and the third door panel 63. When the second side of the left rotating seat 2 and the second side of the right rotating seat 3 are close to each other, the first door panel 61 and the third door panel 63 are both rotated relative to the second door panel 62 and close to each other (that is, the first door panel 61 and the third door panel 63 are close to each other). When the second side of the left rotating seat 2 and the second side of the right rotating seat 3 are away from each other, the first door panel 61 and the third door panel 63 are both rotated relative to the second door panel 62 and away from each other (that is, the first door panel 61 and the third door panel 63 are away from each other), and the first door panel 61, the second door panel 62, and the third door panel 63 are coplanar. It can be understood that, at this time, the second door panel 62 is provided with a groove, a blind hole or a through hole for embedding the fixing seat 1; or, as long as the thickness of the first door panel 61 is equal to that of the third door panel 63, and its thickness is greater than that of the second door panel 62, the thickness of the fixing seat 1 is offset to ensure that the first door panel 61, the second door panel 62, and the third door panel 63 are coplanar. In addition, a handle (not shown in the figure) is connected to the outer side of the second door panel 62. More preferably, the width of the first door panel 61 is greater than the width of the second door panel 62, and is equal to the width of the third door panel 63.

[0061] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
