Description
Technical Field
[0001] This utility model relates to the field of furniture accessories technology, specifically to a support column for a corner cabinet turntable basket. Background Technology
[0002] In existing technologies, corner cabinets are typically equipped with turntable baskets to make full use of corner space, and the uprights, as the supporting structure for the turntable baskets, are crucial in terms of stability and ease of installation. In traditional upright structures, the connection between the top mount and the telescopic sleeve is mostly achieved through an insertion connection, with the length of the telescopic sleeve fixed by a locking mechanism.
[0003] However, in actual use, the frequent rotation and load of the turntable basket will generate continuous radial and axial forces on the column. This dynamic load can easily cause the insertion connection between the top seat and the telescopic sleeve and the locking mechanism to loosen. The insertion connection between the top seat and the telescopic sleeve lacks an effective axial anti-disengagement structure. The two rely only on friction to limit the movement. There is a risk that the telescopic sleeve may accidentally come out of the top seat, which may cause the entire turntable basket to overturn, posing a safety hazard. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a column for a corner cabinet turntable basket, which makes the top seat and the telescopic sleeve locked together by locking blocks and locking grooves, effectively preventing axial separation between the top seat and the telescopic sleeve and avoiding the risk of the turntable basket tipping over.
[0005] This utility model provides a support column for a corner cabinet turntable basket, including a telescopic sleeve with a locking mechanism, a base installed at the bottom end of the telescopic sleeve, and a top seat installed at the top end of the telescopic sleeve. The top end of the telescopic sleeve is provided with a locking groove. A first cylinder is provided on the top seat, and a locking block is protruding from the inner wall of the first cylinder. The top end of the telescopic sleeve is inserted into the first cylinder, and the locking block is engaged in the locking groove.
[0006] Specifically, the locking groove is an L-shaped groove, which includes a vertical groove and a horizontal groove connected as one piece. The vertical groove extends from the top end of the telescopic sleeve to the bottom end of the telescopic sleeve, and the horizontal groove extends along the circumference of the telescopic sleeve. When the locking block is engaged in the locking groove, the locking block first engages in the vertical groove, and then engages in the horizontal groove; When the locking block disengages from the locking groove, the locking block first moves out of the horizontal groove, and then moves out of the vertical groove.
[0007] Specifically, the locking block has a cuboid structure, a cube structure, or a cylindrical structure.
[0008] Specifically, the top seat also includes a first disc, which is integrally formed with the first cylinder. The first disc and the first cylinder are coaxial, and the first disc is provided with at least three first countersunk holes, which are distributed at equal intervals around the first cylinder.
[0009] Specifically, at least two first reinforcing ribs are protruding from the first disc, and the at least two first reinforcing ribs are distributed at equal intervals around the first cylinder, with one end of any one of the first reinforcing ribs connected to the circumferential surface of the first cylinder.
[0010] Specifically, the telescopic sleeve includes an outer sleeve and a telescopic tube. The bottom end of the outer sleeve is fixedly connected to the base, and the top end of the outer sleeve is provided with the locking mechanism. The bottom end of the telescopic tube passes through the locking mechanism and is inserted into the outer sleeve. The top end of the telescopic tube is provided with the locking groove, and the top end of the telescopic tube is inserted into the first cylinder.
[0011] Specifically, the locking mechanism consists of an inner locking sleeve and an outer locking adjusting sleeve. The inner locking sleeve includes, from bottom to top, a snap-fit cylinder, a snap-fit ring, and a snap-fit claw portion connected as a single unit. The snap-fit claw portion includes multiple claw petals arranged in a circumferential array. The outer circumferential surface of the lower section of the snap-fit claw portion is provided with a first thread. The outer diameter of the upper section of the snap-fit claw portion gradually decreases from bottom to top. The outer locking adjustment sleeve includes a constraint inner sleeve and a gripping outer sleeve connected as one piece. The lower section of the constraint inner sleeve is wrapped inside the gripping outer sleeve, and the upper section of the constraint inner sleeve protrudes outside the gripping outer sleeve. The inner circumferential surface of the lower section of the constraint inner sleeve is provided with a second thread, and the inner diameter of the upper section of the constraint inner sleeve gradually decreases from bottom to top. The snap-fit sleeve is snapped into the outer sleeve, the top end of the outer sleeve is embedded in the snap-fit ring, the constraint inner sleeve is fitted on the snap-fit claw, the first thread and the second thread are engaged, and the gripping outer sleeve covers the snap-fit ring; The telescopic tube passes through the claw portion, the locking ring, and the locking cylinder, and the claw flap is squeezed and locked by the upper section of the constraint inner sleeve to secure the telescopic tube.
[0012] Specifically, the outer sleeve has several mounting holes for rotating arm components on its circumferential surface.
[0013] Specifically, the base includes a second disc and a second cylinder formed on the second disc. The second disc and the second cylinder are coaxial. The second disc is provided with at least three second countersunk holes, which are distributed at equal intervals around the second cylinder. The second cylinder is embedded in the bottom end of the telescopic sleeve, and the bottom end of the telescopic sleeve is connected to the second disc.
[0014] Specifically, at least two second reinforcing ribs are protruding from the second disc, and the at least two second reinforcing ribs are distributed at equal intervals around the second cylinder, with one end of any second reinforcing rib connected to the circumferential surface of the second cylinder; The bottom end of the telescopic sleeve is provided with at least two latches, which are engaged with the at least two second reinforcing ribs one by one.
[0015] Compared with the prior art, the beneficial effects of this utility model are: In the corner cabinet turntable basket support column of this utility model, the top end of the telescopic sleeve is inserted into the first cylinder of the top seat, and the top seat and the telescopic sleeve are engaged by locking blocks and locking grooves. The locking blocks and locking grooves form a mechanical interlocking structure, which forms a rigid block in the axial direction, fundamentally eliminating the possibility of the top end of the telescopic sleeve coming out of the first cylinder, that is, effectively preventing the axial separation between the top seat and the telescopic sleeve, and avoiding the risk of the turntable basket overturning.

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides a support column for a corner cabinet turntable basket. Figure 1 The diagram shows a three-dimensional structural schematic of the corner cabinet turntable basket support column in an embodiment of the present invention. The corner cabinet turntable basket support column includes a telescopic sleeve 200 with a locking mechanism 100, a base 300 installed at the bottom end of the telescopic sleeve 200, and a top seat 400 installed at the top end of the telescopic sleeve 200. Figure 2 The diagram shows an exploded cross-sectional view of the top end and the top seat of the telescopic sleeve in an embodiment of the present invention. The top end of the telescopic sleeve 200 is provided with a locking groove 210; the top seat 400 is provided with a first cylinder 410, and a locking block 411 is protruding from the inner wall of the first cylinder 410. Figure 3 The diagram shows an overall cross-sectional view of the top end and the top seat of the telescopic sleeve in an embodiment of the present invention. The top end of the telescopic sleeve 200 is inserted into the first cylinder 410, and the locking block 411 is engaged in the locking groove 210.
[0021] The installation process of the uprights for the corner cabinet turntable basket of this utility model is as follows: First, fix the base 300 to the preset installation position on the corner cabinet bottom plate; then, install the top seat 400 onto the top of the telescopic sleeve 200, so that the locking block 411 is engaged in the locking groove 210; next, install the telescopic sleeve 200 onto the base 300, and adjust the telescopic length of the telescopic sleeve 200 so that the top seat 400 at the top contacts the corner cabinet top plate; then, fix the current length of the telescopic sleeve 200 by the locking mechanism 100, and fix the top seat 400 onto the corner cabinet top plate; finally, install the rotating arm assembly of the turntable basket onto the telescopic sleeve 200, and install the turntable basket body onto the rotating arm assembly, and the installation is complete.
[0022] In the corner cabinet turntable basket support column of this utility model, the top end of the telescopic sleeve 200 is inserted into the first cylinder 410 of the top seat 400, and the top seat 400 and the telescopic sleeve 200 are engaged by the locking block 411 and the locking groove 210. The locking block 411 and the locking groove 210 form a mechanical interlocking structure, which forms a rigid block in the axial direction, fundamentally eliminating the possibility of the top end of the telescopic sleeve 200 coming out of the first cylinder 410, that is, effectively preventing the axial separation between the top seat 400 and the telescopic sleeve 200, and avoiding the risk of the turntable basket overturning.
[0023] Moreover, no matter how the turntable basket rotates or shakes, as long as the structure of the first cylinder 410, the locking block 411 and the locking groove 210 is intact, the connection point will not loosen due to vibration or impact, and its stability is far superior to that of threaded connections that rely on preload.
[0024] In some specific embodiments, please refer to Figure 2 The locking groove 210 is an L-shaped groove, which includes a vertical groove 211 and a horizontal groove 212 connected as one piece. The vertical groove 211 extends from the top end of the telescopic sleeve 200 to the bottom end of the telescopic sleeve 200, and the horizontal groove 212 extends along the circumference of the telescopic sleeve 200. When the locking block 411 is engaged in the locking groove 210, the locking block 411 first engages in the vertical groove 211 and then engages in the horizontal groove 212. When the locking block 411 is disengaged from the locking groove 210, the locking block 411 first moves out of the horizontal groove 212 and then moves out of the vertical groove 211.
[0025] After the locking block 411 enters the transverse groove 212, it forms a purely mechanical lock. As long as it is not actively rotated to unlock, the telescopic sleeve 200 cannot be dislodged from the top seat 400 under any circumstances (such as vibration, upward / downward lifting, load impact), completely solving the safety hazard of axial dislodgement and ensuring extremely high reliability in preventing dislodgement. Moreover, the locking block 411 is easy and quick to engage and disengage without the need for any tools.
[0026] Specifically, the locking block 411 is a cuboid, cube, or cylinder structure. The cuboid / cube structure has sharp edges and corners, forming surface contact with the wall of the L-shaped groove 212. This results in a large contact area, uniform force distribution, reduced wobbling, and excellent connection rigidity and stability. The cylindrical structure has a smooth curved surface without sharp corners, forming line contact with the groove wall of the L-shaped groove. This minimizes friction and ensures smooth operation during insertion. Preferably, the locking block 411 is a cuboid or cube structure, providing excellent stability.
[0027] Figure 4 The diagram shows a three-dimensional structural schematic of the top seat in an embodiment of the present invention. The top seat 400 further includes a first disk 420, which is integrally formed with the first cylinder 410. The first disk 420 and the first cylinder 410 are coaxial. The first disk 420 is provided with at least three first countersunk holes 421, which are distributed at equal intervals around the first cylinder 410.
[0028] The first disc 420 and the first cylinder 410 are integrally formed, eliminating gaps and assembly errors between parts. This makes the entire top base 400 a robust whole, with uniform stress distribution when subjected to complex loads (such as lateral forces and torsional forces) from the turntable basket, making it less prone to deformation or breakage. Its structural strength is far superior to a split design. Furthermore, the coaxial design of the first disc 420 and the first cylinder 410 ensures that the center of force coincides with the center of support, allowing forces to be perfectly transferred along the axial direction of the column to the top plate of the cabinet. This avoids additional bending moments caused by eccentric loads, making the column more stable. Moreover, the use of at least three equally spaced mounting points (first countersunk holes 421) perfectly adapts to the plane of the top plate of the cabinet, ensuring that the first disc 420 remains firmly attached to the top plate without warping or wobbling under any circumstances, forming the most stable support foundation. In addition, the first countersunk hole 421 allows the screw head to be completely embedded in the hole without protruding from the surface of the first disc 420, resulting in a neat appearance after installation and preventing the screw head from scratching items inside the cabinet; the conical surface of the first countersunk hole 421 can fit tightly with the screw head, transmitting the tightening force more evenly to the first disc 420, reducing local stress and preventing crushing.
[0029] For details, please refer to Figure 4The first disk 420 has at least two protruding reinforcing ribs 430, which are evenly distributed around the first cylinder 410. One end of any of the first reinforcing ribs 430 is connected to the circumferential surface of the first cylinder 410. The first reinforcing ribs 430 can significantly enhance the bending and deformation resistance of the first disk 420, and can also prevent stress concentration at the connection between the first cylinder 410 and the first disk 420, thereby greatly reducing the risk of cracking in this area due to stress concentration.
[0030] Figure 5 This diagram shows an exploded view of the uprights for the corner cabinet turntable basket in an embodiment of the present invention. The telescopic sleeve 200 includes an outer sleeve 220 and a telescopic tube 230. Please refer to [link / reference]. Figure 1 The bottom end of the outer tube 220 is fixedly connected to the base 300, and the top end of the outer tube 220 is provided with the locking mechanism 100. The bottom end of the telescopic tube 230 passes through the locking mechanism 100 and is inserted into the outer tube 220; please refer to Figure 3 The top end of the telescopic tube 230 is provided with the locking groove 210, and the top end of the telescopic tube 230 is inserted into the first cylinder 410. The outer tube 220 provides the main support function, and the telescopic tube 230 and the locking mechanism 100 cooperate to provide the height adjustment function.
[0031] Figure 6 An exploded view of the locking mechanism in an embodiment of the present invention is shown. The locking mechanism 100 is composed of an inner locking sleeve 110 and an outer locking adjusting sleeve 120. The inner locking sleeve 110 includes, from bottom to top, a snap-fit cylinder 111, a snap-fit ring 112, and a snap-fit claw portion 113 connected as a single unit. The snap-fit claw portion 113 includes a plurality of claw petals 1131 arranged in a circumferential array. The outer circumferential surface of the lower section of the snap-fit claw portion 113 is provided with a first thread 1132. The outer diameter of the upper section of the snap-fit claw portion 113 gradually decreases from bottom to top. Figure 7 A cross-sectional structural schematic diagram of the outer locking adjustment sleeve in an embodiment of the present invention is shown. The outer locking adjustment sleeve 120 includes a constraint inner sleeve 121 and a gripping outer sleeve 122 connected as one piece. The lower section of the constraint inner sleeve 121 is wrapped inside the gripping outer sleeve 122, and the upper section of the constraint inner sleeve 121 protrudes outside the gripping outer sleeve 122. The inner circumferential surface of the lower section of the constraint inner sleeve 121 is provided with a second thread 1211, and the inner diameter of the upper section of the constraint inner sleeve 121 gradually decreases from bottom to top. Figure 8The diagram shows a cross-sectional view of the locking mechanism on the telescopic sleeve in an embodiment of the present invention. The snap-fit cylinder 111 is snapped into the outer sleeve 220. The top end of the outer sleeve 220 is embedded in the snap-fit ring 112. The constraint inner sleeve 121 is sleeved on the claw portion 113. The first thread 1132 and the second thread 1211 are engaged. The gripping outer sleeve 122 covers the snap-fit ring 112. The telescopic tube 230 passes through the claw portion 113, the locking ring 112 and the locking cylinder 111, and the claw flap 1131 is squeezed and locked by the upper section of the constraint inner sleeve 121 to lock the telescopic tube 230.
[0032] The core of the locking mechanism 100 lies in using a conical surface and a thread to convert axial rotational motion into radial contraction motion.
[0033] The locking process of the locking mechanism 100 is as follows: Rotate the gripping sleeve 122 (outer locking adjustment sleeve 120) clockwise. Since the inner locking sleeve 110 is fixed, the outer locking adjustment sleeve 120 will rotate and move downwards under the guidance of the thread. As the outer locking adjustment sleeve 120 moves downwards, the inner surface (inner conical surface) of the upper section of the inner sleeve 121 (whose inner diameter gradually decreases from bottom to top) will begin to contact and squeeze the outer surface (outer conical surface) of the upper section of the claw part 113 (whose outer diameter gradually decreases from bottom to top), forcing all claw petals 1131 to contract inwards synchronously and evenly. The contracted claw petals 1131 are like a powerful "claw", firmly holding the telescopic tube 230 passing through it, locking it through huge static friction force, and preventing it from moving up and down.
[0034] The unlocking process of the locking mechanism 100 is as follows: Rotate the gripping sleeve 122 (outer locking adjustment sleeve 120) counterclockwise. Since the inner locking sleeve 110 is fixed, the outer locking adjustment sleeve 120 will rotate and move upward under the guidance of the thread. As the outer locking adjustment sleeve 120 moves upward, the inner surface (inner conical surface) of the upper section of the inner sleeve 121 (whose inner diameter gradually decreases from bottom to top) will gradually leave the outer surface (outer conical surface) of the upper section of the claw part 113 (whose outer diameter gradually decreases from bottom to top). That is, the inner conical surface will gradually leave the outer conical surface of the claw flap 1131. The radial pressure applied to the claw flap 1131 disappears. The elastic claw flap 1131 opens outward and returns to its original shape due to the elasticity of its own material, thereby releasing the clamping force on the telescopic tube 230. At this time, the telescopic tube 230 can freely extend and retract to adjust the height.
[0035] For details, please refer to Figure 1 or Figure 5The outer sleeve 220 has several rotating arm assembly mounting holes 221 on its circumferential surface. The outer sleeve 220 provides the main support function, responsible for supporting the core functional component—the rotating arm assembly, on which the pull basket is mounted.
[0036] Figure 9 A three-dimensional structural schematic diagram of the base in an embodiment of the present invention is shown. The base 300 includes a second disk 310 and a second cylinder 320 formed on the second disk 310. The second disk 310 and the second cylinder 320 are coaxial. The second disk 310 is provided with at least three second countersunk holes 311, which are evenly distributed around the second cylinder 320. The second cylinder 320 is embedded in the bottom end of the telescopic sleeve 200, and the bottom end of the telescopic sleeve 200 is connected to the second disk 310.
[0037] The second disc 310 and the second cylinder 320 are also integrally molded, eliminating connection gaps and assembly errors between parts. This makes the entire base 300 a robust whole, with uniform stress distribution when subjected to complex loads from the turntable basket (such as pressure, lateral force, and torsion), making it less prone to deformation or breakage. Its structural strength is far superior to that of a split design. Moreover, the coaxial design of the second disc 310 and the second cylinder 320 ensures that the center of force coincides with the center of support. Force can be perfectly transferred to the cabinet base plate along the axial direction of the column, avoiding additional bending moments caused by eccentric loads and making the column more stable. Furthermore, the use of at least three equally spaced mounting points (second countersunk holes 311) can perfectly adapt to the plane of the cabinet base plate, ensuring that the second disc 310 fits the cabinet base plate tightly without warping or wobbling under any circumstances, forming the most stable support foundation. In addition, the second countersunk hole 311 allows the screw head to be completely embedded in the hole without protruding from the surface of the second disc 310, resulting in a neat appearance after installation and preventing the screw head from scratching items inside the cabinet. The conical surface of the second countersunk hole 311 can fit tightly with the screw head, transmitting the tightening force more evenly to the second disc 310, reducing local stress and preventing crushing.
[0038] For details, please refer to Figure 9 The second disk 310 has at least two protruding reinforcing ribs 330, which are evenly distributed around the second cylinder 320. One end of each reinforcing rib 330 is connected to the circumferential surface of the second cylinder 320. The reinforcing ribs 330 can significantly enhance the bending and deformation resistance of the second disk 310, and can also prevent stress concentration at the connection between the second cylinder 320 and the second disk 310, thereby greatly reducing the risk of cracking in this area due to stress concentration.
[0039] Figure 10 An exploded structural diagram of the bottom end of the telescopic sleeve and the base in an embodiment of this utility model is shown. The bottom end of the telescopic sleeve 200 is provided with at least two latches 222, which are engaged one-to-one with at least two second reinforcing ribs 330. The cooperation between the second reinforcing ribs 330 and the latches 222 is like installing a "key" and a "keyway" at the connection. During installation, simply align the latches 222 at the bottom of the telescopic sleeve 200 with the second reinforcing ribs 330 on the base 300 and insert it to complete the circumferential (rotational direction) positioning. Once engaged, the side of the second reinforcing rib 330 fits tightly against the side wall of the latch 222, forming a strong mechanical interlock that can effectively resist torque and ensure that the outer sleeve 220 of the telescopic sleeve 200 will not rotate relative to the base 300 under any usage state.
[0040] The corner cabinet turntable basket support column of this utility model has its top end of the telescopic sleeve 200 inserted into the first cylinder 410 of the top seat 400. The top seat 400 and the telescopic sleeve 200 are engaged by the locking block 411 and the locking groove 210. The locking block 411 and the locking groove 210 form a mechanical interlock structure, which forms a rigid block in the axial direction. This fundamentally eliminates the possibility of the top end of the telescopic sleeve 200 coming out of the first cylinder 410, thus effectively preventing the axial separation between the top seat 400 and the telescopic sleeve 200 and avoiding the risk of the turntable basket overturning.
[0041] Furthermore, the bottom end of its telescopic sleeve 200 is fitted over the second cylinder 320 of the base 300 (the second cylinder 320 is embedded in the bottom end of the telescopic sleeve 200), and the base 300 and the telescopic sleeve 200 are engaged by the second reinforcing rib 330 and the bayonet 222. The side of the second reinforcing rib 330 is tightly fitted with the side wall of the bayonet 222, forming a strong mechanical interlock that can effectively resist torque and ensure that the outer sleeve 220 of the telescopic sleeve 200 will not rotate relative to the base 300 under any usage state.
[0042] In essence, the top seat 400 and the base 300 have the same structure and can be used interchangeably without needing to distinguish between them, making them convenient and quick to use. Moreover, this means that the top seat 400 and the base 300 can be produced using the same injection mold, reducing the investment in injection molds and lowering production costs.
[0043] The above provides a detailed description of a corner cabinet turntable basket support column provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
