Description

Technical Field

[0001] The invention relates to the field of home furnishings, and in particular to a rotating cabinet track guide rotating structure and a rotating cabinet thereof. Background Art

[0002] In customized home products, there is often a demand for rotating cabinets. The existing technology is to make an inscribed circular cabinet in a right-angle cabinet. The circular cabinet can be rotated to facilitate the storage of items. The implementation method is to install turntables on the top and bottom of the cabinet so that the cabinet can rotate around the top and bottom axes. At the same time, four universal wheels are installed under the bottom plate to support the weight of the cabinet, so that the circular cabinet can rotate smoothly in the right-angle cabinet. However, there are the following problems: the inscribed circular cabinet in the right-angle cabinet has low space utilization; the processing of the circular cabinet requires a CNC milling machine and a special-shaped edge banding machine, and the processing efficiency is low.

[0003] The invention disclosure document with application number CN202311247396.5 discloses a double-track rectangular rotating cabinet. Although it also describes the placement of limiters and rotating tracks, it can ensure that the movable cabinet moves according to the established rotating track to store items. The cabinet can be automatically reset along the track through the spring, and the damping can make the movement stroke more gentle and noiseless, and will not cause the items in the cabinet to shake and fall due to instantaneous changes in speed. Although the public document can effectively solve the above problems, the design scheme contains multiple components, such as sliders, tracks, rotating components, positioning columns, etc., which increase the complexity of the overall structure. In the production and assembly process, higher precision and more process steps may be required, thereby increasing the manufacturing cost and assembly difficulty. And because the design includes multiple sliding and rotating components, especially the contact surfaces of the slider and the linear track, rotating track, etc., the friction between these components may cause wear problems in long-term use. With the accumulation of wear, the smoothness and stability of the cabinet may be affected, reducing the service life. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a rotating cabinet track-guided rotating structure with excellent stability and durability, and to provide a rotating cabinet equipped with a rotating cabinet track-guided rotating structure, so as to have smooth rotation control, strong load capacity and efficient space utilization.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] The swivel seat is provided with a plurality of rollers, the plurality of rollers are provided with rollers that are arranged on the rollers inner side of the rollers and ...

[0007] Preferably, both sides of the groove inside the linear track are convex, and the periphery of the rolling pulley is concave inward.

[0008] Preferably, the two dampers are symmetrically arranged to facilitate assembly with the two claws.

[0009] Preferably, the number of rolling pulleys installed on each support block is three, and the position of the rolling pulley in the middle is offset inward by half a body position.

[0010] Preferably, a circular arc-shaped rotation guide groove is welded on the plate surface of the movable plate facing the fixed plate, and a shaft head mounting hole for assembling with the shaft head is also opened at the center point of the movable plate 1;

[0011] Furthermore, both ends of the rotary guide groove extend to the diagonal positions of the movable plate respectively, which can expand the guide stroke of the rotary guide groove.

[0012] Preferably, a positioning guide column is fixedly mounted on a corner of the fixed plate facing the movable plate by screws, and a ball bearing is arranged at the end of the positioning guide column.

[0013] Furthermore, the operation steps of the rotating cabinet track guide rotating structure are:

[0014] Step 1: The movable plate and the fixed plate are in a relatively static position, and the rotating seat is installed in the track on the fixed plate. Ensure that all components are correctly aligned and that point A of the rotating guide groove abuts against the positioning guide column;

[0015] Step 2: The user applies an external force or manually pushes the movable plate to make it start to rotate clockwise. At this time, point A of the rotating guide groove is separated from the positioning guide column. The rotating seat body slides toward the positioning guide column on two linear tracks through rolling pulleys to bring the movable plate part out of the fixed plate. At the same time, the claw moves with the rotating seat body to pull the damper. When the rotating seat body is extremely close to the positioning guide column, point B of the rotating guide groove coincides with the positioning guide column.

[0016] Step 3: The movable plate rotates clockwise with the shaft head as the axis, and the inertial force of the rotation is used. At this time, point B of the rotating guide groove still coincides with the positioning guide column. After the movable plate completes the clockwise rotation with the shaft head, the damper pulls the claw to retract the rotating seat body for reset, and point B of the rotating guide groove moves away from the positioning guide column. After the damper pulls the claw to retract the rotating seat body to complete the reset, point C of the rotating guide groove coincides with the positioning guide column to complete the entire rotation stroke. At this time, point A of the rotating guide groove and point B of the rotating guide groove are swapped, and point C of the rotating guide groove is located on the other side of the rotating seat body;

[0017] Step 4: The user applies an external force or manually pushes the movable plate to make it start to rotate counterclockwise. At this time, point C of the rotating guide groove is separated from the positioning guide column. The rotating seat body slides toward the positioning guide column on two linear tracks through rolling pulleys to bring the movable plate part out of the fixed plate. At the same time, the claw moves with the rotating seat body to pull the damper. When the rotating seat body is extremely close to the positioning guide column, point B of the rotating guide groove coincides with the positioning guide column.

[0018] Step 5: The movable plate rotates counterclockwise with the shaft head as the axis, and uses the inertial force of rotation. At this time, point B of the rotating guide groove still coincides with the positioning guide column. After the movable plate completes the counterclockwise rotation with the shaft head, the damper pulls the claw to retract the swivel body for reset. Point B of the rotating guide groove moves away from the positioning guide column. After the damper pulls the claw to retract the swivel body to complete the reset, point A of the rotating guide groove coincides with the positioning guide column to complete the entire rotation stroke. At this time, the initial state of the step is restored.

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0035] Example

[0036] A rotating cabinet track guide rotating structure, such as Figure 1-3 As shown, it includes a movable plate 1, a fixed plate 2 having the same area as the movable plate 1, and a rotating component 3 located between the movable plate 1 and the fixed plate 2 and assembled with the movable plate 1 and the fixed plate 2 respectively.

[0037] An arc-shaped rotation guide groove 11 is welded on the plate surface of the movable plate 1 facing the fixed plate 2, and a shaft head mounting hole 12 assembled with the shaft head 333 is also opened at the center point of the movable plate 1; the two ends of the rotation guide groove 11 extend to the diagonal points of the movable plate 1 respectively, which can expand the guide stroke of the rotation guide groove 11.

[0038] A positioning guide column 21 is fixedly installed at a corner of the fixed plate 2 facing the movable plate 1 by screws, and a ball 211 is provided at the end of the positioning guide column 21. Specifically, the end of the positioning guide column 21 is inserted into the rotating guide groove 11 and contacts with the rotating guide groove 11 through the ball 211. The ball 211 improves the smoothness of sliding, thereby avoiding jamming during the rotation of the movable plate 1.

[0039] like Figure 4-5 As shown, the rotating assembly 3 includes two linear rails 31 which are fixedly mounted on the fixed plate 2 in parallel and have grooves, a damper 32 which is arranged on the inner side of the two linear rails 31 and fixedly mounted on the fixed plate 2, and a rotating seat 33 which is movably assembled with the movable plate 1 at the upper end and movably assembled with the linear rails 31 and the damper 32 at the lower end. The rotating seat 33 includes a rotating seat body 331, a fixed bearing 332 which is embedded in the center of the rotating seat body 331, a shaft head 333 which is mounted in cooperation with the fixed bearing 332 and assembled with the movable plate 1, support blocks 334 which are fixedly mounted below the two ends of the rotating seat body 331 by screws, a plurality of rolling pulleys 335 which are mounted below the support block 334 by a fixed shaft and are installed in the internal groove of the linear rail 31, and two claws 336 which are symmetrically mounted on one side of the rotating seat body 331 by screws and abut against the hook of the damper 32.

[0040] The groove inside the linear track 31 has protrusions on both sides, and the outer periphery of the rolling pulley 335 is recessed inwardly. Specifically, the rolling pulley 335 with a recessed outer periphery can cooperate with the protruding part of the groove inside the linear track 31, which can prevent the rolling pulley 335 from sliding from the linear track 31, thereby affecting the linear sliding of the rotating seat 33.

[0041] The two dampers 32 are symmetrically arranged to facilitate assembly with the two claws 336. Specifically, the claws 336 move with the rotating seat body 331 to pull the dampers 32, or during the resetting process, the dampers 32 pull the claws 336 to retract the rotating seat body 331.

[0042] There are three rolling pulleys 335 installed on each support block 334, and the position of the rolling pulley 335 in the middle is offset inward by half a body length. Specifically, because the position of the rolling pulley 335 in the middle is offset inward by half a body length, the three rolling pulleys 335 are arranged in an arc shape, which can effectively reduce the gap between the rolling pulley 335 and the internal groove of the linear rail 31, so that the rotating seat 33 can move smoothly in a linear manner on the two linear rails 31.

[0043] like Figure 6-8 As shown, the operation steps of the rotating cabinet track guide rotating structure are:

[0044] Step 1: The movable plate 1 and the fixed plate 2 are in a relatively static position, and the rotating seat 33 is installed in the track 31 on the fixed plate 2, ensuring that each component is correctly aligned, and point A of the rotating guide groove 11 abuts against the positioning guide column 21;

[0045] Step 2: The user applies an external force or manually pushes the movable plate 1 to make the movable plate 1 start to rotate clockwise. At this time, point A of the rotating guide groove 11 is separated from the positioning guide column 21. The rotating seat body 331 slides toward the positioning guide column 21 on the two linear rails 31 through the rolling pulley 335 to bring the movable plate 1 partially out of the fixed plate 2. At the same time, the claw 336 moves with the rotating seat body 331 to pull the damper 32. When the rotating seat body 331 is extremely close to the positioning guide column 21, point B of the rotating guide groove 11 coincides with the positioning guide column 21.

[0046] Step 3: The movable plate 1 rotates clockwise with the shaft head 333 as the axis, and the inertial force of the rotation is used. At this time, point B of the rotating guide groove 11 still coincides with the positioning guide column 21. After the movable plate 1 completes the clockwise rotation with the shaft head 333, the damper 32 pulls the claw 336 to retract the rotating seat body 331 for reset, and point B of the rotating guide groove 11 moves away from the positioning guide column 21. After the damper 32 pulls the claw 336 to retract the rotating seat body 331 to complete the reset, point C of the rotating guide groove 11 coincides with the positioning guide column 21 to complete the entire rotation stroke. At this time, point A of the rotating guide groove 11 and point B of the rotating guide groove 11 are swapped, and point C of the rotating guide groove 11 is located on the other side of the rotating seat body 331;

[0047] Step 4: The user applies an external force or manually pushes the movable plate 1 to make the movable plate 1 start to rotate counterclockwise. At this time, point C of the rotating guide groove 11 is separated from the positioning guide column 21. The rotating seat body 331 slides toward the positioning guide column 21 on the two linear rails 31 through the rolling pulley 335 to bring the movable plate 1 partially out of the fixed plate 2. At the same time, the claw 336 moves with the rotating seat body 331 to pull the damper 32. When the rotating seat body 331 is extremely close to the positioning guide column 21, point B of the rotating guide groove 11 coincides with the positioning guide column 21.

[0048] Step 5: The movable plate 1 rotates counterclockwise with the shaft head 333 as the axis, and uses the inertial force of rotation. At this time, point B of the rotating guide groove 11 still coincides with the positioning guide column 21. After the movable plate 1 completes the counterclockwise rotation with the shaft head 333, the damper 32 pulls the claw 336 to retract the swivel body 331 for reset, and point B of the rotating guide groove 11 moves away from the positioning guide column 21. After the damper 32 pulls the claw 336 to retract the swivel body 331 to complete the reset, point A of the rotating guide groove 11 coincides with the positioning guide column 21 to complete the entire rotation stroke, and the initial state of step 1 is restored.

[0049] The present invention also provides a rotating cabinet, comprising a rotating cabinet track guide rotating structure, such as Fig. 9 As shown, the rotating cabinet includes an outer fixed cabinet body 4, an inner movable cabinet body 5 located inside the outer fixed cabinet body 4, and a rotating cabinet track guide rotating structure is arranged at the upper and lower ends of the outer fixed cabinet body 4, and is fixedly installed with the outer fixed cabinet body 4 and the inner movable cabinet body 5.

[0050] A frame 41 is fixedly installed at the upper and lower ends of the external fixed cabinet body 4, and a cover plate 42 is fixed on the frame 41 by screws. Specifically, the rotating cabinet track guide rotating structure is installed inside the frame 41, and the fixed plate 2 and the cover plate 42 in the rotating cabinet track guide rotating structure are fixed by screws.

[0051] Rectangular cavities 51 are provided at the upper and lower ends of the inner movable cabinet body 5. Specifically, the rectangular cavity 51 is used for the movable plate 1 in the rotating structure of the rotating cabinet track guide, and is fixedly installed with the movable plate 1 by screws.

[0052] Therefore, combined with the running state diagram of the rotating cabinet track-guided rotating structure, the state change diagram of the combined door opening of the inner movable cabinet and the outer fixed cabinet in the rotating cabinet is as follows: Fig.10 shown.

[0053] Therefore, combined with the running state diagram of the rotating cabinet track-guided rotating structure, the state change diagram of the combined door opening of the inner movable cabinet and the outer fixed cabinet in the rotating cabinet is as follows: Fig.11 shown.

[0054] It should be further explained that the clockwise or counterclockwise rotation of the rotating cabinet track guide rotating structure during operation does not affect the combined opening and closing process of the rotating cabinet, which depends on the actual installation direction of the rotating cabinet track guide rotating structure.

[0055] The above embodiments of the present invention are not intended to limit the protection scope of the present invention, and the implementation modes of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structures of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in the art, without departing from the above basic technical ideas of the present invention, should fall within the protection scope of the present invention.
