Description

Technical Field

[0001] The utility model relates to the technical field of cabinets, and particularly relates to a sliding door. Background Art

[0002] Sliding doors are widely used in products such as cabinets because of their convenient use and small space occupation.

[0003] Generally, sliding parts are respectively arranged at the top and bottom of the sliding door, and slide rails are correspondingly arranged on the top frame and bottom frame of the cabinet opening. The sliding parts are embedded in the sliding grooves of the slide rails and are in sliding fit with the sliding grooves, so as to realize the push-pull sliding of the sliding door relative to the cabinet opening, and further realize the opening or closing of the sliding door.

[0004] To reduce friction and improve sliding smoothness, in some sliding doors, at least the sliding parts at the top or bottom are rollers. The rollers are rotatably installed on the sliding door through a rotating shaft, and the number of the rollers is multiple. The multiple rollers are arranged at intervals along the push-pull direction of the sliding door.

[0005] Taking the sliding parts at the bottom of the sliding door as an example, due to problems such as the installation accuracy of the rollers themselves, the processing accuracy of the sliding door itself, or a slight slope of the ground, there may be a situation where the installation heights of multiple rollers are inconsistent, so that the lowest points of the multiple rollers are not at the same height position. Furthermore, after the sliding door is installed on the cabinet opening, there is an inclination problem, so that the width of the gap (abbreviation: closing gap) between the vertical side of the closing side of the sliding door and the corresponding side plate of the cabinet opening in the closed state is inconsistent in the up-down direction. For example, the width of the closing gap gradually increases or gradually decreases from bottom to top, thus affecting the closing tightness of the sliding door.

To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or reference letters in different examples.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0055] In some embodiments of the present application, a sliding door is proposed, which is used for sliding installation on the cabinet opening of a cabinet. Slide rails are respectively installed on the top plate and the bottom plate of the cabinet opening, and the slide rails are slidably matched with the top and bottom of the sliding door.

[0056] Generally, multiple sliding doors are arranged front and back. Multiple slide rails are correspondingly arranged on the top plate and the bottom plate of the cabinet opening. The multiple sliding doors are lap-mounted on the cabinet opening. By pushing and pulling the sliding doors, the cabinet can be opened or closed.

[0057] In some embodiments of the present application, referring to Figures 1 to 10 , the sliding door includes a door panel 100, a top sliding member 210, and a plurality of rollers 300.

[0058] The outer contour of the door panel 100 is rectangular, and its circumferential side surfaces include a door panel top surface 110, a door panel bottom surface 120, a door panel left side surface, and a door panel right side surface.

[0059] The top sliding member 210 is provided at the top of the door panel 100, and in the installed state of the sliding door, the top sliding member 210 protrudes upward from the door panel top surface 110 so as to be embedded in the slide rail on the top plate of the cabinet opening and slidably cooperate with the slide rail.

[0060] As Figure 1 and Figure 2 shown, the top sliding member 210 can be multiple plate-shaped members or block-shaped members arranged at intervals in the width direction of the door panel 100, and of course, it can also be a roller or the like, and specific limitations are not required here.

[0061] As Figures 1 to 5 shown, multiple rollers 300 are arranged at intervals in the width direction of the door panel 100 at the bottom of the door panel 100. The rollers 300 include roller bodies 310 and mounting components. The mounting components include fixing components 320 and adjustable components 330. The fixing components 320 are fixed on the door panel 100, and the roller bodies 310 are rotatably mounted on the adjustable components 330 and protrude downward from the door panel bottom surface 120 so as to be embedded in the slide rail on the bottom plate of the cabinet opening and slidably cooperate with the slide rail.

[0062] The adjustable component 330 is mounted on the fixing component 320, and the adjustable component 330 is configured to be adjustable in position relative to the fixing component 320 so as to drive the roller body 310 to perform position adjustment, specifically to realize the height adjustment of the roller body 310.

[0063] In the sliding door according to the embodiment of the present invention, on the one hand, by adjusting the position of the adjustable component 330, the height of the roller body 310 can be adjusted, that is, the distance h (as Figure 3 shown) that the lowest point of the roller body 310 protrudes downward from the door panel bottom surface 120, and then the sliding door can be adjusted to solve the problem of the inclination of the sliding door, so that the closing gap of the sliding door in the closed state can have the same width up and down, and the closing tightness of the sliding door is improved.

[0064] On the other hand, by adjusting the position of the adjustable component 330, the height of the roller body 310 can be adjusted, and multiple roller bodies 310 can also be effectively contacted with the slide rail on the bottom plate of the cabinet opening, so that the sliding door can be reliably supported and the deformation of the sliding door is reduced.

[0065] In some embodiments of the present application, as Figures 1 to 5 shown, the number of rollers 300 is two, which are respectively close to the left and right ends at the bottom of the door panel 100, and the support for the door panel 100 is reliable and the adjustment is convenient.

[0066] Of course, the number of rollers 300 can also be adjusted according to the sizes of different door panels 100, and no specific limitation is provided herein.

[0067] In some embodiments of the present application, the adjustable component 330 is rotatably arranged on the fixed component 320, and the rotation axis of the adjustable component 330 is not coaxial with the rotation axis of the roller body 310. Then, the roller body 310 can not only rotate itself, but also rotate around the rotation axis of the rotatable component along with the rotation of the adjustable component 330. Furthermore, the position of the roller body 310 can be adjusted, that is, the height position of the roller body 310 can be adjusted, that is, the height of its protrusion downward relative to the top surface 110 of the door panel can be adjusted, so that the sliding door can be adjusted.

[0068] A positioning member 340 is also connected between the adjustable component 330 and the fixed component 320, which is used to position the adjustable component 330 after the adjustable component 330 rotates in place, and further position the roller body 310 at the adjusted position.

[0069] In some embodiments of the present application, the adjustable component 330 is rotatably connected to the fixed component 320 through a rotating shaft. That is, the rotating shaft serves as both the rotating connection member between the adjustable component 330 and the fixed component 320 and the rotation axis of the adjustable component 330.

[0070] The position of the rotating shaft of the adjustable component 330 is located in the upper region of the roller body 310. An arc-shaped hole 331 is also formed on the adjustable component 330, and the arc-shaped hole 331 can protrude upward. A threaded round hole 321 is correspondingly formed on the fixed component 320. The positioning member 340 is a threaded fastener, such as a bolt, which passes through the arc-shaped hole 331 and is threadedly engaged with the threaded round hole 321.

[0071] In the normal installation state, the positioning member 340 is in a tightened state to ensure that the adjustable component 330 and the roller body 310 are stably installed on the fixed component 320.

[0072] When it is necessary to adjust the height of the roller body 310, that is, to adjust the distance that the lowest point of the roller body 310 protrudes downward from the bottom surface 120 of the door panel, only need to loosen the positioning member 340, and then push the adjustable component 330 to make it rotate. The arc-shaped hole 331 provides an avoidance space for the rotation of the adjustable component 330. After the roller body 310 is adjusted in place, tighten the positioning member 340 to fasten the adjustable component 330.

[0073] Such as Figure 3 、 Figures 6 to 10As shown, in some embodiments of the present application, two arc-shaped holes 331 are arranged at intervals along the rotation direction of the adjustable component 330, and the arc-shaped holes 331 are located above the rotation axis of the adjustable component 330 and the roller body 310. The arc-shaped holes 331 protrude upward, and the internally threaded round holes 321 are arranged in one-to-one correspondence with the arc-shaped holes 331.

[0074] Similarly, in some embodiments of the present application, the positioning member 340 is a threaded fastener, such as a bolt, which is arranged in one-to-one correspondence with the internally threaded round holes 321. The positioning member 340 passes through the arc-shaped holes 331 and is threadedly engaged with the internally threaded round holes 321.

[0075] At this time, the connection between the adjustable component 330 and the fixed component 320 can be directly achieved through the cooperation of the two positioning members 340 and the internally threaded round holes 321, without additionally setting a rotating shaft. Since the position of the fixed component 320 remains unchanged, the center positions of the two internally threaded round holes 321 remain unchanged, and the rotation center of the adjustable component 330 is the center O of the same circle where the centers a and b of the two internally threaded round holes 321 are located. As Figure 8 shown, the roller mounting hole 332 on the adjustable component 330 deviates from the center O, that is, the rotation axis of the roller body 310 is not coaxial with the rotation axis of the adjustable component 330.

[0076] In the normal installation state, the positioning members 340 are in a tightened state to ensure that the adjustable component 330 and the roller body 310 are stably installed on the fixed component 320.

[0077] When it is necessary to adjust the height of the roller body 310, that is, to adjust the distance that the lowest point of the roller body 310 protrudes downward from the bottom surface 120 of the door panel, only need to loosen the two positioning members 340, and then push the adjustable component 330 to make it rotate. The two arc-shaped holes 331 provide an avoidance space for the rotation of the adjustable component 330; after the roller body 310 is adjusted in place, tighten the two positioning members 340 to fasten the adjustable component 330.

[0078] As Figure 3 、 Figures 6 to 8 shown in the installation perspective, rotating the adjustable component 330 clockwise can increase the distance that the roller 300 body protrudes downward from the bottom surface 120 of the door panel, that is, make the position of the rotation axis of the roller 300 body closer to the bottom surface 120 of the door panel; while rotating the adjustable component 330 counterclockwise can decrease the distance that the roller 300 body protrudes downward from the bottom surface 120 of the door panel, that is, make the position of the rotation axis of the roller 300 body away from the bottom surface 120 of the door panel. Corresponding adjustment marks 333 (such as taking the rotation direction of the adjustable direction as the mark) can be set on the adjustable component 330 to improve the adjustment convenience.

[0079] In some embodiments of the present application, as Figures 6 to 10As shown, the adjustable component 330 and the fixed component 320 are provided with a coarse positioning structure 350 that cooperate with each other. The coarse positioning structure 350 is located between two arc-shaped holes 331.

[0080] The coarse positioning structure 350 includes a round hole formed on the adjustable component 330 and a corresponding round hole formed on the fixed component 320. When the adjustable component 330 is installed on the fixed component 320, the round hole on the adjustable component 330 can be aligned with the round hole on the fixed component 320 first to coarsely position the position of the adjustable component 330, and then the positioning member 340 is installed to improve the assembly efficiency. After the positioning member 340 is installed, the position of the roller body 310 is adjusted by operating the positioning member 340.

[0081] Of course, the coarse positioning structure 350 can also be other structures, such as mutually cooperating positioning marks, etc., and specific limitations are not required here.

[0082] In some embodiments of the present application, the roller 300 is located on the back side of the door panel 100, that is, the fixed component 320, the adjustable component 330, and the roller body 310 are located on the back side of the door panel 100, so as to realize the hidden installation of the roller 300 as much as possible and improve the overall aesthetics of the sliding door.

[0083] The fixed component 320 is formed with a first protruding portion 322 that bends and protrudes away from the door panel 100, so that an installation avoidance gap 323 is formed between the first protruding portion 322 and the back surface of the door panel 100. The adjustable component 330 is installed on the first protruding portion 322, and the first protruding portion 322 is located between the installation avoidance gap 323 and the adjustable component 330, that is, the installation avoidance gap 323 and the adjustable component 330 are respectively located on the front and back sides of the first protruding portion 322.

[0084] The installation avoidance gap 323 provides an avoidance space for the installation and fastening of the connecting member between the adjustable component 330 and the fixed component 320, such as the positioning member 340. The positioning member 340 passes through the arc-shaped hole 331 from the side where the adjustable component 330 is located and is threadedly fastened and cooperated with the internal thread round hole 321. The end of the positioning member 340 can extend into the installation avoidance gap 323.

[0085] In some embodiments of the present application, the fixed component 320 can be fixedly arranged on the back surface of the door panel 100 by welding or riveting.

[0086] In some embodiments of the present application, such as Figures 6 to 10As shown, a second protruding portion 334 that bends and protrudes toward the installation avoidance gap 323 is formed on the adjustable member 330. The roller body 310 is rotatably installed in the recessed space surrounded by the second protruding portion 334. An avoidance portion 324 is formed on the first protruding portion 322 to avoid the second protruding portion 334 being embedded in the installation avoidance gap 323.

[0087] With this structure, the entire roller 300 can have a more compact structure, with a smaller thickness in the front-back direction (i.e., the horizontal direction perpendicular to the direction of the door panel 100), minimizing the space occupied inside the cabinet.

[0088] In some embodiments of the present application, as Figure 1 、 Figure 2 and Figure 4 shown, a press-forming strengthening structure 130 is formed on the door panel 100 to enhance the overall structural strength of the sliding door. The door panel 100 can be made of cold-rolled steel plate, such as SPCC cold-rolled steel plate or other metal plates, and the press-forming strengthening structure 130 can specifically be formed by stretch forming.

[0089] As a specific implementation manner, the press-forming strengthening structure 130 can be formed by stretching from the back side to the front side of the door panel 100 to form a large-area rectangular protrusion, and then stretching from the front side to the front side of the large-area rectangular protrusion to form a plurality of small-area rectangular grooves. The multi-directional stretching further improves the structural strength of the sliding door.

[0090] In some embodiments of the present application, referring to Figures 11 to 13 , and combining with Figure 1 and Figure 2 , the top sliding member 210 of the sliding door is a thin plate member. Taking the two top sliding members 210 arranged at intervals along the width direction of the door panel 100 as shown in Figure 1 and Figure 2 as an example for illustration. The top of the top sliding member 210 protrudes upward above the top surface 110 of the door panel so as to be able to be inserted into the slide rail on the top plate of the cabinet opening.

[0091] In some embodiments of the present application, the top sliding member 210 is a metal plate member, and a rubber sleeve 240 is sleeved on its top end to play a role in lubrication and noise reduction.

[0092] In some embodiments of the present application, as Figure 3 、 Figures 11 to 13 shown, a first connecting plate 220 is connected to the top of the back surface of the door panel 100. A second connecting plate 230 is connected to the first connecting plate 220. A limiting sliding groove 231 that penetrates up and down is provided on the second connecting plate 230. The top sliding member 210 is inserted into the limiting sliding groove 231, and the overall top sliding assembly 200 is formed. The top sliding member 210 can slide upward in the limiting sliding groove 231 to the installation state and slide downward to the disassembly state.

[0093] The top slider 210 in the installed state protrudes upward from the top surface 110 of the door panel so as to be inserted into the slide rail on the top plate of the cabinet opening and slidably cooperate with the slide rail; for the top slider 210 in the disassembled state, the top slider 210 does not protrude from the top surface 110 of the door panel, that is, the top slider 210 retracts below the top surface 110 of the door panel or the top end of the top slider 210 is flush with the top surface 110 of the door panel.

[0094] By setting the top slider 210 to a structure that can slide up and down, quick installation and disassembly of the door panel 100 can be achieved, thereby facilitating the use of the cabinet.

[0095] When installing the sliding door, first fit the rollers 300 at the bottom of the door panel 100 into the slide rail on the bottom plate of the cabinet opening, and make the top slider 210 slide downward to the disassembled state. Then align the top slider 210 of the door panel 100 with the slide rail on the top plate of the cabinet opening, and slide the top slider 210 upward to the installed state, so that the top slider 210 extends into the slide rail on the top plate of the cabinet opening to complete the installation of the sliding door.

[0096] When disassembling the sliding door, slide the top slider 210 downward so that the top slider 210 disengages from the slide rail on the top plate of the cabinet opening, thereby allowing the door panel 100 to be separated from the slide rail on the top plate of the cabinet opening; then tilt the door panel 100 outward and remove the sliding door from the slide rail on the bottom plate of the cabinet opening.

[0097] To facilitate the downward sliding operation of the top slider 210, a downward pulling operation member 260, such as a pull rope or a pull rod, is connected to the top slider 210. The downward pulling operation member 260 can extend downward to a height convenient for pulling, so that the user or installer can pull the top slider 210 downward by stretching. When the top slider 210 needs to be slid upward, the top slider 210 needs to be manually pushed upward.

[0098] In some embodiments of the present application, a horizontal bending portion 211 that bends away from the side where the door panel 100 is located is formed at the bottom end of the top slider 210, and the top end of the downward pulling operation member 260 is connected to the horizontal bending portion 211 of the top slider 210. On the one hand, the horizontal bending portion 211 can serve as a connecting portion for the downward pulling operation member 260, and on the other hand, it can serve as an upward pushing operation portion for the top slider 210 to facilitate the upward pushing and sliding operation of the top slider 210.

[0099] In some embodiments of the present application, the first connecting plate 220 is installed on the back surface of the door panel 100 by screws, and the second connecting plate 230 is connected to the first connecting plate 220 by bolts.

[0100] Two stoppers 232 are further provided on the second connecting plate 230, and the two stoppers 232 are respectively located on both sides of the limit sliding groove 231; the top sliding member 210 is in surface contact with both stoppers 232, and the two stoppers 232 play a role in limiting the top sliding member 210 to prevent the top sliding member 210 from falling off the limit sliding groove 231 in the front-rear direction.

[0101] A vertically extending limit sliding hole 233 is provided on the second connecting plate 230, and a limit post 250 is vertically provided on the top sliding member 210. The limit post 250 extends out of the limit sliding hole 233 and slides up and down along the limit sliding hole 233.

[0102] In some embodiments of the present application, the limit sliding hole 233 is in the shape of a barbell hole with larger diameters at both ends and a smaller diameter in the middle.

[0103] When the top sliding member 210 is in the installed state, the limit post 250 is stuck at the junction of the upper large-diameter hole and the middle small-diameter section hole of the limit sliding hole 233, as Figure 11 shown.

[0104] When the top sliding member 210 is in the disassembled state, the limit post 250 is supported on the lower large-diameter hole of the limit sliding hole 233.

[0105] When the top sliding member 210 slides from the installed state to the disassembled state, a downward force needs to be applied to the top sliding member 210 to cause its limit post 250 to extrude the middle small-diameter section hole of the limit sliding hole 233 to produce elastic deformation, and then enter the lower large-diameter hole of the limit sliding hole 233.

[0106] Then the limit sliding hole 233 plays a role in limiting and guiding the up and down sliding of the limit post 250, so as to play a role in limiting and guiding the up and down sliding of the top sliding member 210.

[0107] In some embodiments of the present application, a sliding door is proposed, which includes a door panel 100, a top sliding member 210 and rollers 300. The top sliding member 210 is provided at the top of the door panel 100, and in the installed state, the top sliding member 210 protrudes upward from the top surface 110 of the door panel so as to be embedded in the sliding rail on the top plate of the cabinet opening and slide in cooperation with the sliding rail; a plurality of rollers 300 are arranged at intervals along the width direction of the door panel 100 at the bottom of the door panel 100 and protrude downward from the bottom surface 120 of the door panel so as to be embedded in the sliding rail on the bottom plate of the cabinet opening and slide in cooperation with the sliding rail.

[0108] The roller 300 is configured to be height-adjustable, so that the distance h by which it protrudes downward from the bottom surface 120 of the door panel is adjustable.

[0109] In the description of the above embodiments, the specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0110] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
