Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to an upward-opening door structure and a cabinet body. Background Art

[0002] A swing door is a door that rotates around a horizontal axis to achieve opening and closing, also known as a rocking door. When closed, the door leaf is in a vertical state. When opened, the vertical door leaf is rotated to a horizontal position or other positions through rotation. When the swing door is opened, the space inside the cabinet can be fully displayed. The rotation structure of the swing door is similar to that of an opening door. The door panel is mostly fixed on the top plate or the bottom plate and is flipped downward or upward along the horizontal axis to open. Its connection with the cabinet body can use ordinary hinges or special swing door hinges. Swing doors can be divided into upward-opening doors and downward-opening doors according to their installation positions and opening and closing directions. The upward-opening door opens by flipping upward from the bottom; the downward-opening door rotates downward from the upper end and generally can be opened to the horizontal position.

[0003] The existing swing door structure has deficiencies in terms of operation convenience, safety, and aesthetics. For example, when the existing door panel is flipped downward, a position for the handle needs to be reserved above the handle. And when the cabinet body is placed at a too high position, the operation of manually translating the door panel out from a high place is not convenient, and both hands need to be in a raised state all the time. When the door panel is flipped downward, the handle needs to be held all the time. If the hand is released, it will hit the door stop below and produce a loud noise, and there is also a risk of pinching the hand when flipping downward. Summary of the Utility Model

[0004] Aiming at the defects existing in the above prior art, one of the purposes of the present utility model is to provide an upward-opening door structure to solve the problems that when the existing door panel is flipped downward, a handle position needs to be reserved on the door panel, and when the door panel is at a too high position, the door panel needs to be manually translated out from a high place and the door panel needs to be supported by hand throughout the process.

[0005] One of the purposes of the present utility model is realized by adopting the following technical solutions:

[0006] An upward-opening door structure includes a door panel, two side plates, a top plate, a bottom plate, and a bumper. The top plate, the bottom plate, and the two side plates enclose an accommodation space. The door panel is arranged at the open end of the accommodation space. Slide grooves are respectively arranged on the opposite side surfaces of the two side plates. The slide grooves extend along the width direction of the side plates. Rotating members are respectively arranged on the opposite sides of the top of the door panel. The rotating members are rotatably connected with the slide grooves and can reciprocally slide along the slide grooves. The door panel has a storage state, an intermediate state, and a closed state. The bumper is arranged on the side surface opposite to the door panel. The bumper is used to provide a force that causes the door panel to switch from the storage state to the intermediate state when the door panel is acted on by an external force. After the door panel pops out a preset distance, the door panel switches from the intermediate state to the closed state under its own gravity.

[0007] Further, auxiliary rolling members are respectively provided on the opposite side surfaces of the two side plates. The chute includes a limiting end portion which is open and arranged close to the accommodating space. The auxiliary rolling members are arranged close to the limiting end portion. The auxiliary rolling members are used for rolling contact with the door panel and can provide a fulcrum to the door panel to assist the door panel to turn downward.

[0008] Further, the auxiliary rolling members are silent auxiliary rollers.

[0009] Further, a damper is provided at the bottom of the top plate. The damper is used for elastically contacting the top end portion of the door panel when the door panel switches from the intermediate state to the closed state.

[0010] Further, a silent door stopper is provided on the side plate. The silent door stopper is used for contacting the door panel when the door panel switches to the closed state to limit the door panel in the closed state.

[0011] Further, when the door panel is in the closed state, the door panel is arranged to incline outward and downward from the top to the bottom.

[0012] Further, a J-shaped handle is provided at the bottom of the door panel.

[0032] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repetitive description will be omitted.

[0033] The words expressing positions and directions described in this utility model are illustrative with reference to the accompanying drawings, but can be changed according to needs, and all changes made are included in the protection scope of this utility model.

[0034] Embodiment 1

[0035] As Figure 1-8 shown, an upward-opening door structure provided by this utility model includes a door panel 1, two side plates 2, a top plate 3, a bottom plate 4 and a rebounder 5. The top plate 3, the bottom plate 4 and the two side plates 2 enclose a receiving space, and the door panel 1 is disposed at the open end of the receiving space. Chutes 6 are respectively provided on the opposite side surfaces of the two side plates 2, and the chutes 6 extend along the width direction of the side plates 2. Rotating members 7 are respectively provided on the opposite sides of the top of the door panel 1, and the rotating members 7 are rotatably connected to the chutes 6 and the rotating members 7 can reciprocally slide along the chutes 6. The door panel 1 has a storage state, an intermediate state and a closed state. The rebounder 5 is disposed on the side surface opposite to the door panel 1, and the rebounder 5 is used to provide a force for promoting the door panel 1 to switch from the storage state to the intermediate state when the door panel 1 is subjected to an external force. After the door panel 1 pops out a preset distance, the door panel 1 switches from the intermediate state to the closed state under its own gravity.

[0036] In this embodiment, when the door panel 1 is in the storage state, the door panel 1 is located below the top plate 3 and parallel to the top plate 3. At this time, the opening of the accommodating space is unobstructed. When the door panel 1 is in the closed state, the door panel 1 closes the opening of the accommodating space. When the door panel 1 is in the storage state, pressing the door panel 1 causes the door panel 1 to automatically slide outwards under the action of the rebounder 5. After the door panel 1 pops out a preset distance, the door panel 1 automatically switches from the intermediate state to the closed state under its own gravity. Thus, the entire process from when the door panel 1 pops out to when it descends does not require manual operation. Therefore, to switch the door panel 1 from the storage state to the closed state, only one pressing action is needed to complete the closing of the door panel 1, greatly improving the operation convenience. Additionally, by providing the rebounder 5, there is no need to leave a handle position on the door panel 1, improving the aesthetic appearance of the door panel 1. Therefore, the up - turning door structure of the present utility model solves the problems that in the prior art, when the door panel 1 is turned downwards, a handle position needs to be reserved on the door panel 1, and when the door panel 1 is at a too high position, it is necessary to manually translate the door panel 1 out from a high place and hold the door panel 1 with hands throughout the process.

[0037] As a preferred embodiment, auxiliary rolling members 8 are respectively provided on the opposite side surfaces of the two side plates 2. The chute 6 includes a limiting end portion disposed close to the opening of the accommodating space. The auxiliary rolling members 8 are disposed close to the limiting end portion. The auxiliary rolling members 8 are used for rolling contact with the door panel 1 and can provide a fulcrum to the door panel 1 to assist the door panel 1 in turning downwards.

[0038] In this embodiment, referring to Figure 4-8 , under the action of the rebounder 5, the door panel 1 slides outwards along the chute 6, and the auxiliary rolling members 8 assist the door panel 1 to slide out, making the sliding - out effect smoother. When the door panel 1 slides out completely, under the limitation of the chute 6 and the self - gravity of the door panel 1, the door panel 1 takes the auxiliary rolling members 8 as a fulcrum, the top end of the door panel 1 tilts upwards, and the bottom end of the door panel 1 descends, causing the door panel 1 to switch from the intermediate state to the closed state. Therefore, by providing the auxiliary rolling members 8, the sliding of the door panel 1 can be assisted and the door panel 1 can be supported during flipping.

[0039] As a preferred embodiment, the auxiliary rolling member 8 is a silent auxiliary roller. In this way, the door panel 1 can play a silent role during sliding, further enhancing the experience.

[0040] As a preferred embodiment, a damper 9 is provided at the bottom of the top plate 3. The damper 9 is used for elastically contacting the top end portion of the door panel 1 when the door panel 1 switches from the intermediate state to the closed state.

[0041] In this embodiment, when the door panel 1 needs to be closed, press the door panel 1. The door panel 1 pops outwards under the action of the rebounder 5. After the door panel 1 slides out completely, under the action of its own gravity and the auxiliary rolling member 8, the bottom end of the door panel 1 drops, and at the same time the end of the door panel 1 gradually rises and contacts the damper 9 installed on the top plate 3, causing the door panel 1 to slowly descend and finally switch to the closed state. By setting the damper 9, after releasing the hand, the door panel 1 has a damping effect and will not produce a large sound. Since the door panel 1 descends slowly, it prevents something from suddenly reaching in from below and being pinched, making the operation more convenient and safe, and solving the problems that the traditional door panel 1 lacks a damping function when flipping down and is prone to generating noise and impacts.

[0042] As a preferred embodiment, the side plate 2 is provided with a silent door stopper 10, and the silent door stopper 10 is used to contact the door panel 1 when the door panel 1 switches to the closed state to limit the door panel 1 in the closed state.

[0043] In this embodiment, by setting the silent door stopper 10, on the one hand, it plays a silent role when the door panel 1 and the silent door stopper 10 come into contact when the door panel 1 flips down, and on the other hand, it limits the flipping angle of the door panel 1.

[0044] As a preferred embodiment, when the door panel 1 is in the closed state, the door panel 1 is inclined outward and downward from the top to the bottom, and a J-shaped handle 12 is provided at the bottom of the door panel 1.

[0045] In this embodiment, by increasing the J-shaped handle 12 and the inclination angle of the door panel 1, wherein the inclination angle can be designed according to the height of the door panel 1 to produce a better visual effect, so that books, newspapers or magazines can be placed in front of the door panel 1, improving the storage function and the overall decorative effect, and solving the defect that there is no storage function in front of the door panel 1 after the existing door panel 1 flips down.

[0046] In summary, referring to Figure 4-8 , the working principle of the upward-opening door structure is as follows: After pressing the J-shaped handle 12, the rebounder 5 is triggered, and the rebounder 5 slides the door panel 1 outwards. The rotating member 7 on the door panel 1 slides in the chute 6 to ensure that the door panel 1 does not shake. At the same time, the auxiliary rolling member 8 assists the door panel 1 to slide out, making the sliding-out effect smoother. After the door panel 1 slides out completely, under the limiting function of the chute 6 and the auxiliary rolling member 8 and the action of the self-gravity of the door panel 1, the handle end of the door panel 1 drops, and the rear end of the door panel 1 rises to contact the damper 9 installed on the top plate 3, causing the door panel 1 to slowly descend until it contacts the silent door stopper 10 for limiting.

[0047] As a preferred embodiment, a light strip 13 is provided at the bottom of the top plate 3 corresponding to the position of the J-shaped handle 12, and an embedding groove for installing the light strip 13 is provided at the bottom of the top plate 3.

[0048] In this embodiment, an embedded light bar 13 is added to the top plate 3. Through the illumination of the light, the books, newspapers or magazines placed in front of the door panel 1 have a more decorative atmosphere effect. The setting of the embedding groove can, on the one hand, achieve the effect of convenient installation of the light bar 13, and on the other hand, facilitate the hidden installation of the light bar 13 to avoid interfering with the sliding process of the door panel 1.

[0049] As a preferred embodiment, the rotating member 7 is a silent pulley, and the silent pulley is detachably connected to the door panel 1. In this embodiment, the rotating member 7 of the silent pulley is rotatably connected to the sliding groove 6. In this way, the rotating member 7 can play a silent role when sliding in the sliding groove 6, and at the same time, the sliding is smooth, improving the experience; in addition, the silent pulley is detachably connected to the door panel 1, which can achieve the effect of quick disassembly and maintenance.

[0050] As a preferred embodiment, it further includes a limit reinforcement plate 11. The limit reinforcement plate 11 is located below the top plate 3 and is vertically connected to the top plate 3. An embedding hole for installing the rebounder 5 is provided in the middle of the limit reinforcement plate 11.

[0051] In this embodiment, by arranging the limit reinforcement plate 11 below the top plate 3 and installing the rebounder 5 on the limit reinforcement plate 11, on the one hand, the rebounder 5 can be well hidden, and on the other hand, an embedding hole is opened on the limit reinforcement plate 11, and the rebounder 5 is fixed on the limit reinforcement plate 11 by an embedding method, which is convenient for installation and does not occupy the storage space. The rebounder 5 in this embodiment is preferably a rubber head rebounder 5, so that the door panel 1 makes a silent effect when pushed in. Of course, in other embodiments, the rebounder 5 can also be a magnetic head rebounder 5.
