Description

Technical Field

[0001] This invention relates to the field of doors, and provides a door assembly and a storage cabinet. Background Technology

[0002] In related technologies, the hinge structure between the door and the cabinet of a storage cabinet mostly adopts the form of hinged to a door pivot. Taking refrigerators as an example, the hinge structure between the door and the door pivot is mostly quite complex, with low reliability, and the actual process of disassembling and assembling the door is cumbersome. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the related art. To this end, the present invention proposes a door assembly that simplifies the hinge structure between the door assembly and the door hinge, while ensuring the stability of the hinge connection between the door body and the door hinge.

[0004] The present invention also proposes a storage cabinet.

[0005] A first aspect of the present invention provides a gate assembly, comprising:

[0006] Door body;

[0007] A rotating component is rotatably mounted on the door body and adapted to switch between a rotating state and a reset state, and a first limiting portion is formed on the rotating component;

[0008] A locking member is rotatably mounted on the door body, and a second limiting portion is formed on the locking member;

[0009] In the reset state, the first limiting part is adapted to abut against the second limiting part, so that the door body is hinged to the door hinge by the locking member;

[0010] From the reset state to the rotation state, the first limiting part is adapted to disengage from the second limiting part to unlock the locking member.

[0011] According to the door assembly provided in the first aspect of the present invention, a rotating member that can switch between a rotating state and a reset state is provided on the door body, and a first limiting part is provided on the rotating member. Correspondingly, a locking member that cooperates with the rotating member is provided on the door body, and a second limiting part that cooperates with the first limiting part is provided on the locking member. When the rotating member is in the reset state, the first limiting part can abut against the second limiting part, thereby locking the rotation state of the locking member. At this time, the door body can be hinged to the door body through the locking member. When the rotating member switches from the reset state to the rotating state, the first limiting part on the reset member can disengage from the second limiting part on the locking member, thereby unlocking the locking member. At this time, the locking member is in a rotatable state. As the user opens the door body, the locking state of the locking member relative to the door hinge is unlocked, and the locking member can disengage from the door hinge as the door body moves, allowing the user to open the door body. When the user closes the door, the locking element, under the action of the door hinge, contacts and rotates relative to the hinge. During this process, the second limiting part on the locking element abuts against the first limiting part on the rotating element, and the first limiting part again limits the second limiting part. At this point, the rotation of the locking element is locked, thus achieving the purpose of hinged connection between the door and the cabinet. This design not only achieves the purpose of installing the door in the cabinet but also simplifies the hinge structure between the door and the cabinet, improving the reliability of the hinge connection. Furthermore, when it is necessary to change the door's opening direction, only the corresponding structure needs to be installed at the corresponding position on the door, and the opening direction can be adjusted by operating the corresponding structure on that side of the door. This also enables quick adjustment of the door's opening direction, avoiding the need to remove the door and reinstall the hinges in related technologies, thus expanding the door's applicability.

[0012] According to one embodiment of the present invention, the first limiting portion is formed on the end face of the rotating member facing the inner side of the door body;

[0013] The locking element includes:

[0014] A snap-fit ​​section, wherein a snap-fit ​​section is formed with a groove suitable for engaging with the door hinge;

[0015] A limiting segment is formed on the limiting segment, and a protrusion is formed on the limiting segment facing the rotating member. The end face of the protrusion facing the outside of the door body constitutes the second limiting part.

[0016] In the reset state, the end face of the protrusion facing the outer side of the door body is adapted to abut against the end face of the rotating member facing the inner side of the door body.

[0017] According to one embodiment of the present invention, the door assembly further includes an elastic member, the two ends of which abut against the door body and the side of the rotating member facing the locking member, respectively. When the slot is engaged with the door hinge, the elastic member is adapted to drive the rotating member to switch from the rotating state to the reset state.

[0018] According to one embodiment of the present invention, the door assembly further includes a handle plate hinged to the door body, the handle plate being adapted to switch between a first state and a second state, from the first state to the second state, and the handle plate being adapted to drive the rotating member to switch from the reset state to the rotating state.

[0019] According to one embodiment of the present invention, the handle plate includes:

[0020] A handle, which is hinged to the door body;

[0021] An extension is connected to the handle and extends toward the inside of the door body, and the side of the extension toward the handle is adapted to abut against the rotating member.

[0022] According to one embodiment of the present invention, a groove is formed at the bottom of the door body, and the handle plate is rotatably connected to the side wall of the groove.

[0023] According to one embodiment of the present invention, an avoidance groove is formed on the door body at a position corresponding to the door hinge.

[0024] According to one embodiment of the present invention, there are two rotating members and two locking members, which are respectively arranged along the height direction of the door body, and a connecting rod is provided between the two rotating members.

[0025] According to one embodiment of the present invention, the door assembly further includes a pulley rotatably mounted on the door body.

[0026] A second aspect of the present invention provides a locker including the door assembly described above.

[0027] According to the second aspect of the present invention, the storage cabinet provided by setting the above-mentioned door assembly not only improves the installation efficiency between the door and the cabinet and simplifies the installation structure, but also enables the adjustment of the door opening direction without disassembling the door, thereby improving the versatility of the storage cabinet.

[0028] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0029] According to the door assembly provided in the first aspect of the present invention, a rotating member that can switch between a rotating state and a reset state is provided on the door body, and a first limiting part is provided on the rotating member. Correspondingly, a locking member that cooperates with the rotating member is provided on the door body, and a second limiting part that cooperates with the first limiting part is provided on the locking member. When the rotating member is in the reset state, the first limiting part can abut against the second limiting part, thereby locking the rotation state of the locking member. At this time, the door body can be hinged to the door body through the locking member. When the rotating member switches from the reset state to the rotating state, the first limiting part on the reset member can disengage from the second limiting part on the locking member, thereby unlocking the locking member. At this time, the locking member is in a rotatable state. As the user opens the door body, the locking state of the locking member relative to the door hinge is unlocked, and the locking member can disengage from the door hinge as the door body moves, allowing the user to open the door body. When the user closes the door, the locking element, under the action of the door hinge, contacts and rotates relative to the hinge. During this process, the second limiting part on the locking element abuts against the first limiting part on the rotating element, and the first limiting part again limits the second limiting part. At this point, the rotation of the locking element is locked, thus achieving the purpose of hinged connection between the door and the cabinet. This design not only achieves the purpose of installing the door in the cabinet but also simplifies the hinge structure between the door and the cabinet, improving the reliability of the hinge connection. Furthermore, when it is necessary to change the door's opening direction, only the corresponding structure needs to be installed at the corresponding position on the door, and the opening direction can be adjusted by operating the corresponding structure on that side of the door. This also enables quick adjustment of the door's opening direction, avoiding the need to remove the door and reinstall the hinges in related technologies, thus expanding the door's applicability.

[0030] Furthermore, according to the second aspect of the present invention, the storage cabinet provided by setting the above-mentioned door assembly not only improves the installation efficiency between the door and the cabinet and simplifies the installation structure, but also enables the adjustment of the door opening direction without disassembling the door, thereby improving the versatility of the storage cabinet.

[0043] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0044] like Figures 1 to 8As shown, a first aspect embodiment of the present invention provides a door assembly including a door body 100, a rotating member 102, and a locking member 106; the rotating member 102 is rotatably mounted on the door body 100 and adapted to switch between a rotating state and a reset state, and a first limiting portion 104 is formed on the rotating member 102; the locking member 106 is rotatably mounted on the door body 100 and a second limiting portion 108 is formed on the locking member 106; in the reset state, the first limiting portion 104 is adapted to abut against the second limiting portion 108 so that the door body 100 is hinged to the door hinge 110 via the locking member 106; from the reset state to the rotating state, the first limiting portion 104 is adapted to disengage from the second limiting portion 108 so that the locking member 106 is unlocked.

[0045] According to the door assembly provided in the first aspect of the present invention, a rotating member 102 that can switch between a rotating state and a reset state is provided on the door body 100, and a first limiting part 104 is provided on the rotating member 102. Correspondingly, a locking member 106 that cooperates with the rotating member 102 is provided on the door body 100, and a second limiting part 108 that cooperates with the first limiting part 104 is provided on the locking member 106. When the rotating member 102 is in the reset state, the first limiting part 104 can abut against the second limiting part 108, so that the rotation state of the locking member 106 is locked. At this time, the door body 100 can be hinged to the door body 100 through the locking member 106. When the rotating member 102 switches from the reset state to the rotating state, the first limiting part 104 on the reset member can disengage from the second limiting part 108 on the locking member 106, thereby unlocking the locking member 106. At this time, the locking member 106 is in a rotatable state. As the user opens the door 100, the locking state of the locking member 106 relative to the door hinge 110 is unlocked. Then, the locking member 106 can disengage from the door hinge 110 as the door 100 moves, and the user can open the door 100. When the user closes the door 100, the locking member 106, under the action of the door hinge 110, contacts the door hinge 110 and rotates relative to it. During this process, the second limiting part 108 on the locking member 106 abuts against the first limiting part 104 on the rotating member 102 again. The first limiting part 104 then limits the second limiting part 108, locking the rotation of the locking member 106. This achieves the purpose of hingedly connecting the door 100 to the cabinet. This arrangement not only achieves the purpose of installing the door 100 to the cabinet but also simplifies the hinge structure between the door 100 and the cabinet, improving the reliability of the hinge connection. Meanwhile, when it is necessary to change the opening direction of the door 100, it is only necessary to set the corresponding structure at the corresponding position on the door 100, and adjust the opening direction by operating the corresponding structure on the door 100 on that side. This also realizes the quick adjustment of the opening side direction of the door 100, avoiding the step of disassembling the door 100 and reinstalling the hinges in related technologies, thus improving the applicability of the door 100.

[0046] Please continue reading Figures 1 to 8 The rotating component 102 is installed on the door body 100. In this embodiment of the invention, the rotating component 102 can be installed at the edge of the door body 100, for example, at a corner of the door body 100, which facilitates user operation. The rotating component 102 can switch between a rotating state and a reset state. It can be understood that when the rotating component 102 is rotatable, it is in a rotating state, and when the rotating component 102 returns to its initial position, it is in a reset state.

[0047] In this embodiment of the invention, the rotating member 102 is generally rectangular, and its middle portion is rotatably connected to the door body 100. A first limiting portion 104 for cooperating with the locking member 106 is formed on the rotating member 102. By providing the first limiting portion 104 on the rotating member 102, the state of the locking member 106 can be limited by the limiting effect of the first limiting portion 104, thereby ensuring that the locking member 106 can be hinged to the door hinge 110 so that the door body 100 is stably in a closed state. Alternatively, the locking member 106 can be unlocked so that it is in a rotatable state. When the user opens the door body 100, the locking member 106 can separate from the door hinge 110, at which point the door body 100 can be opened. Of course, in other embodiments, the first limiting portion 104 described above can also be formed by other structures.

[0048] See Figure 7 and Figure 8 In this embodiment of the invention, the first limiting portion 104 is formed on the end face of the rotating member 102 facing the inner side of the door body 100. For example... Figure 7 As shown, the first limiting part 104 can be formed directly from the end face of the rotating member 102 facing the inside of the door body 100.

[0049] In this embodiment of the invention, the locking member 106 is used to hinge the door 100 to the cabinet or to unlock the door 100 from the cabinet. Thus, the locking member 106 is rotatably mounted on the door 100. Correspondingly, to cooperate with the rotating member 102, a second limiting part 108 is formed on the locking member 106 to cooperate with the first limiting part 104. When the rotating member 102 is in the reset state, the first limiting part 104 and the second limiting part 108 abut against each other, locking the rotation of the locking member 106. That is, in this case, the door 100 can be hinged to the door hinge 110 on the cabinet via the locking member 106. When the rotating member 102 switches from the reset state to the rotating state, the first limiting part 104 and the second limiting part 108 disengage from each other. At this time, the rotating state of the locking member 106 is unlocked. When the user opens the door 100, the locking member 106 rotates synchronously with the movement of the door 100, and the locking member 106 can disengage from the door hinge 110 of the cabinet. That is, in this case, the locking state between the door 100 and the cabinet is unlocked, and the user can open the door. When the user closes the door 100, the locking member 106 rotates under the action of the door hinge 110. When the door 100 is completely closed, the locking member 106 returns to its initial position, and at the same time, the first limiting part 104 and the second limiting part 108 abut against each other again, thereby achieving the purpose of closing the door 100.

[0050] According to one embodiment of the present invention, a clearance groove 130 is formed on the door body 100 at a position corresponding to the door hinge 110. This arrangement prevents interference between the door hinge 110 and the door body 100. Simultaneously, when the locking member 106 is in its initial position, that is, when the first limiting part 104 and the second limiting part 108 are pressed together, a stable hinged connection can be achieved with the door hinge 110 through the combined limiting effect of the groove sidewall of the clearance groove 130 and the locking member 106, thereby ensuring the hinge stability between the door body 100 and the door hinge 110.

[0051] According to one embodiment of the present invention, the door assembly further includes a pulley 134, which is rotatably mounted on the door body 100. This arrangement reduces the friction between the door body 100 and other door bodies 100 during opening and closing, thereby improving the smoothness of the user opening or closing the door body 100.

[0052] See Figure 4 In this embodiment of the invention, the locking member 106 includes a snap-fit ​​section 112 and a limiting section 116; wherein, the snap-fit ​​section 112 is formed with a snap groove 114 adapted to cooperate with the door hinge 110; the limiting section 116 is formed with a protrusion facing the rotating member 102, and the end face of the protrusion facing the outside of the door body 100 constitutes a second limiting part 108; in the reset state, the end face of the protrusion facing the outside of the door body 100 is adapted to abut against the end face of the rotating member 102 facing the inside of the door body 100.

[0053] like Figure 4 As shown, the locking member 106 is rotatably mounted on the door body 100 at its middle position. The snap-fit ​​section 112 on the locking member 106 is used to snap onto the door hinge 110, and the limiting section 116 on the locking member 106 is used to limit the movement of the rotating member 102.

[0054] Therefore, in order to achieve the cooperation between the locking section 112 and the door hinge 110, an open slot 114 is formed on the locking section 112. When the locking member 106 is locked in its rotational state, the slot 114 can engage with the door hinge 110 to lock the door 100. When the locking member 106 is unlocked in its rotational state, as the user opens the door 100, the slot 114 can disengage from the door hinge 110 to open the door 100.

[0055] A protrusion is formed on one end of the limiting section 116 facing the rotating member 102, protruding towards the rotating member 102. The end face of this protrusion facing the outer side of the door body 100 forms the second limiting part 108 on the locking member 106. The end face of this protrusion facing the inner side of the door body 100 is an arc-shaped surface. With this configuration, when the first limiting part 104 and the second limiting part 108 disengage from each other, the arc-shaped surface on the second limiting part 108 can smoothly transition with the rotating member 102, reducing the friction between them.

[0056] like Figure 8 As shown, when the first limiting part 104 and the second limiting part 108 are pressed together, the locking member 106 cannot move along the path shown. Figure 8 The counterclockwise rotation shown means that the locking member 106 is fixed in position relative to the door body 100 and will not rotate relative to the door body 100. The door body 100 can be hinged to the door hinge 110 on the cabinet through the locking member 106. When the first limiting part 104 and the second limiting part 108 disengage from each other, the locking member 106 can rotate along the counterclockwise direction as shown. Figure 8 The lock 106 rotates counterclockwise as shown, meaning that it can rotate relative to the door 100. As the door 100 opens, the lock 106 disengages from the door hinge 110. When the user closes the door 100, the slot 114 on the lock 106 engages with the door hinge 110. As the door 100 closes, the door hinge 110 drives the lock 106 to rotate counterclockwise as shown. Figure 8 When the door 100 is fully closed by rotating clockwise as shown, the locking member 106 returns to its initial position under the action of the door hinge 110. At this time, the first limiting part 104 and the second limiting part 108 abut against each other again, thereby stably hinged the door 100 to the cabinet.

[0057] According to one embodiment of the present invention, the door assembly further includes an elastic member 120, the two ends of which abut against the door body 100 and the side of the rotating member 102 facing the locking member 106, respectively. When the slot 114 is engaged with the door hinge 110, the elastic member 120 is adapted to drive the rotating member 102 to switch from a rotating state to a reset state.

[0058] See Figure 7 To achieve the reset of the rotating component 102, an elastic element 120 is also provided between the rotating component 102 and the door body 100. The elastic element 120 mentioned here can be a spring. As mentioned earlier, when the rotating component 102 switches from the reset state to the rotating state, that is, when the rotating component 102 moves along the spring... Figure 7 When rotated clockwise as shown, the elastic element 120 is compressed; when the locking element 106 returns to its initial position, the rotating element 102 can move along the direction shown by the elastic restoring force of the elastic element 120. Figure 7 When the rotating member 102 rotates counterclockwise, the first limiting part 104 and the second limiting part 108 on the rotating member 102 abut against each other, and the rotating member 102 reaches the reset state and stops rotating.

[0059] According to one embodiment of the present invention, the door assembly further includes a handle plate 122, which is hinged to the door body 100. The handle plate 122 is adapted to switch between a first state and a second state, from the first state to the second state. The handle plate 122 is also adapted to drive the rotating member 102 to switch from a reset state to a rotating state.

[0060] See Figure 1 and Figure 5 To facilitate user operation of the rotating component 102, a handle plate 122 is also provided on the door body 100. The handle plate 122 can be located at the bottom edge of the door body 100. To ensure a smooth visual effect on the outer surface of the door body 100, a groove 128 is formed at the bottom of the door body 100, and the two ends of the handle plate 122 are rotatably mounted on the side wall of the groove 128.

[0061] The handle plate 122 can switch between a first state and a second state. When the user does not hold the handle plate 122, the handle plate 122 is in the first state. When the user holds the handle plate 122, the handle is in the second state. That is, when the user applies force to the handle plate 122 to drive it to rotate, the handle plate 122 can switch from the first state to the second state. At the same time, the handle plate 122 can also synchronously drive the rotating component 102 to switch from the reset state to the rotating state.

[0062] According to one embodiment of the present invention, the handle plate 122 includes a handle portion 124 and an extension portion 126; the handle portion 124 is hinged to the door body 100; the extension portion 126 is connected to the handle portion 124 and extends toward the inside of the door body 100, and the side of the extension portion 126 toward the handle portion 124 is adapted to abut against the rotating member 102.

[0063] See Figure 4 The handle 124 is formed on the door handle 124 for easy gripping by the user. An extension 126 is connected to the handle 124 and extends towards the inside of the door body 100. The extension 126 is generally an arc-shaped groove structure. The inner wall of this arc-shaped groove abuts against the end of the rotating member 102 facing the inside of the door body 100. With this arrangement, when the user grips the handle 124, the handle 124 can be rotated. Simultaneously, the handle 124 drives the extension 126 to rotate. As the extension 126 rotates, it can drive the rotating member 102 along... Figure 7 Rotate clockwise as shown.

[0064] As mentioned earlier, when the user releases the handle 124, the elastic element 120 can drive the rotating element 102 to switch from the rotating state to the reset state. At the same time, since the rotating element 102 and the handle plate 122 are in contact with each other, the handle plate 122 can be synchronously driven to return to the first state as the rotating element 102 resets.

[0065] Therefore, in order to achieve the cooperation between the rotating member 102 and the handle plate 122, an abutment end 140 suitable for abutting and cooperating with the extension 126 is also provided at one end of the rotating member 102 facing the extension 126. It can be understood that the part of the rotating member 102 that is hinged to the door body 100 can be the rotating body 138 on the rotating member 102, and the part of the rotating member 102 that cooperates with the handle plate 122 is the abutment end 140.

[0066] In one embodiment of the present invention, in order to ensure the hinge stability between the door 100 and the cabinet, the rotating member 102 and the locking member 106 mentioned above can be arranged at the upper and lower ends of the door 100 along the height direction of the door 100.

[0067] like Figure 5 As shown, two rotating parts 102 and two locking parts 106 can be provided respectively, with the two rotating parts 102 and the two locking parts 106 respectively positioned along the height direction of the door body 100 at its edge. Simultaneously, to achieve synchronous movement of the two rotating parts 102, a connecting rod 132 is provided between them. With this arrangement, when the rotating part 102 located below the door body 100 rotates, the connecting rod 132 causes both rotating parts 102 to rotate synchronously. Meanwhile, the locking part 106 located above the door body 100 operates in the same way as the locking part 106 located below the door body 100, which will not be elaborated here. It is understood that this arrangement improves the hinge stability between the door body 100 and the cabinet.

[0068] The connecting rod 132 can be made of a rigid material to ensure the synchronicity between the two rotating parts 102. For example, a square hole can be made in the rotating part 102, and square shaft sections that fit into the square holes can be provided at both ends of the connecting rod 132. By inserting the square shaft sections into the square holes in the rotating part 102, the synchronous rotation of the rotating part 102 and the connecting rod 132 can be achieved.

[0069] In another embodiment of the present invention, in order to achieve the purpose of opening the door 100 to both the left and right without disassembling the door body 100, a rotating member 102 and a locking member 106 can be respectively arranged on the left and right sides of the door body 100 along the width direction of the door body 100. A connecting member 136 is connected between the two rotating members 102. With this arrangement, when the rotating member 102 on the left side switches from the reset state to the rotating state, the connecting member 136 can be used to tighten the rotating member 102 on the right side. That is, as shown in the figure... Figure 7 As shown, when located as Figure 7 When the rotating member 102 on the left side is rotated clockwise, one end of the bottom of the rotating member 102 faces as shown. Figure 7The leftward movement shown is achieved through the tensioning action of connector 136, positioning it as... Figure 6 The rotating member 102 on the right side shown cannot move along the path shown. Figure 8 As shown, the rotation is counterclockwise. Simultaneously, the first limiting part 104 on the right-side rotating member 102 and the second limiting part 108 on the right-side locking member 106 abut against each other, causing the parts located as shown... Figure 8 The rotating part 102 on the right side shown can be stably held in the reset state. Therefore, the user can open the door 100 from the left side, while the right side of the door 100 can be stably hinged to the cabinet.

[0070] Similarly, when the user opens the door 100 with the right side, the rotating part 102 on the right side can also keep the rotating part 102 on the left side in the reset state by the pulling action of the connecting part 136.

[0071] In this embodiment of the invention, by providing the aforementioned connector 136 on the door body 100, the door body 100 will not shift horizontally when the user opens it from different sides. This is because when the locking member 106 is in its initial position, it can achieve a stable hinged connection with the door hinge 110 due to the combined limiting effect of the side wall of the clearance groove 130 and the locking member 106. This ensures the hinged stability between the door body 100 and the door hinge 110, so the door body 100 will not shift horizontally when the user opens it.

[0072] A second aspect of the present invention provides a locker including the door assembly described above.

[0073] According to the second aspect of the present invention, the locker provided by setting the above-mentioned door assembly not only improves the installation efficiency between the door 100 and the cabinet body and simplifies the installation structure, but also enables the adjustment of the opening direction of the door 100 without disassembling the door 100, thereby improving the versatility of the locker.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
