Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a lifting component for a height-adjustable coffee table. Background Technology

[0002] With the diversification of modern home environments, coffee tables, as the core furniture of the living room, are no longer limited to traditional storage. More and more users hope that coffee tables can have height adjustment functions to adapt to the usage needs of different scenarios such as office, dining or leisure.

[0003] However, existing height-adjustable coffee tables still have some structural shortcomings. The main issue is the traditional height adjustment locking mechanism, which often requires users to bend over and use a handle or knob to unlock and lock, a cumbersome and strenuous operation, especially unfriendly to the elderly or those with mobility issues. Furthermore, most existing height-adjustable components use a single-column sliding support method. To ensure smooth sliding, a certain clearance must be allowed between the components. This results in reduced rigidity between the mounting base and the main body when the coffee table is raised to its highest position, causing the tabletop to wobble easily, severely impacting the user experience and the safety of placed items.

[0004] Therefore, this utility model proposes a lifting component for a height-adjustable coffee table to address the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lifting component for a height-adjustable coffee table, aiming to improve the problems of existing height-adjustable coffee tables, such as cumbersome unlocking and adjustment operations, the need to bend over to operate manually resulting in low ease of use, and tabletop wobbling and poor overall stability due to gaps in the fit after lifting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lifting component for a height-adjustable coffee table, comprising: a housing and a mounting base slidably disposed inside the housing; and an adjustment component;

[0007] The adjustment assembly has a precise mechanical transmission and locking structure. The adjustment assembly includes a fixed base, a foot pedal rotatably disposed inside the fixed base, a sliding inner column slidably disposed inside the outer shell, and an inclined block disposed inside the outer shell.

[0008] Furthermore, the foot pedal, the rotating plate, and the sliding block are combined via a cam-linkage mechanical connection. Specifically, the foot pedal is connected to the rotating plate, a sliding block is slidably positioned within the fixed base, the sliding block engages with the outer wall of the rotating plate and is connected to a rising column, the rising column is connected to the sliding inner column; the mounting base has a slot, the inclined block has an inclined surface structure and is adapted to be inserted into the slot; the sliding inner column has a groove, and when the sliding inner column slides upward, the groove slides along the inclined surface of the inclined block to drive the inclined block to compress into the outer shell and disengage from the slot.

[0009] Preferably, a damper is provided inside the outer casing, and the damper is connected to the inclined block. This damper provides a restoring force to the inclined block when the sliding inner column resets, causing it to slide back into the slot. The damper ensures the automatic reset capability of the locking mechanism and prevents jamming.

[0010] Preferably, when the foot pedal rotates, it causes the rotating plate to swing upward, and the sliding block, limited by the fixed seat, converts the upward swing of the rotating plate into upward motion. This structure efficiently converts rotational motion into linear motion, realizing the conversion of force direction.

[0011] Preferably, the outer wall of the rising column is slidably fitted inside the outer casing, and the rising column slides downwards to reset as the foot pedal and the sliding inner column reset. The rising column not only serves a transmission function but also acts as a bridge connecting the internal and external structures.

[0012] Preferably, the lifting assembly of the height-adjustable coffee table further includes a support assembly, which is disposed on the outer side of the housing to provide auxiliary support. The support assembly includes an outer wall ring fixed to the outer wall of the housing and a sliding column fixed to the bottom end of the mounting base, the sliding column being slidably connected inside the outer wall ring.

[0013] Preferably, a friction block is slidably connected inside the outer wall ring, and a support column is screwed onto the outer wall ring. The support column is used to tighten or loosen the friction block by rotation. The clamping function is achieved through the cooperation of the friction block and the sliding column.

[0014] Preferably, the support column and the outer wall ring are threaded together. When the support column is rotated inward, the friction block is pressed tightly against the outer wall of the sliding column to fix and limit its position. When the support column is rotated outward, the limiting effect on the friction block is released. This threaded drive method is simple to operate and has a large locking force.

[0015] Preferably, after the foot pedal is released, the sliding inner column slides downward and resets under gravity, and the inclined block resets under the rebound of the damper and slides through the slot into the groove. The system automatically returns to its original position using gravity and elasticity, requiring no manual intervention.

[0016] Preferably, the foot pedal, along with the resetting of the sliding inner column, causes the rising column to reset, thereby resetting the foot pedal to its highest position. This ensures that the foot pedal is in a ready state for the next operation.

[0017] Preferably, the bottom of the outer casing is used for support on the ground, and the top of the mounting base is used for fixed connection to the coffee table. This is the basic installation configuration of the component.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by adjusting the coordination of the foot pedal, rotating plate, sliding block, rising column and sliding inner column in the components, utilizes the rotational motion of the foot pedal to convert it into the vertical linear motion of the internal structure, thereby driving the inclined block to move. This solves the problem that the height adjustment of existing height-adjusting coffee tables requires bending over to manually unlock and is inconvenient to operate. It achieves the technical effect of easily unlocking and adjusting by foot pedal operation, and automatically resetting and locking when released, thus improving the user's convenience.

[0020] 2. This utility model solves the problem of inaccurate or stuck reset of the mechanical locking structure after adjustment by setting an inclined drive engagement between the sliding inner column and the inclined block, and by cooperating with the rebound action of the damper. It achieves the technical effect of the inclined block being able to smoothly disengage from and cut into the mounting seat slot, thus realizing accurate and reliable height-level positioning.

[0021] 3. This utility model solves the problem of tabletop wobbling and poor stability caused by the fit gap after the traditional single-column lifting assembly is raised by setting a support assembly including an outer wall ring, a sliding column, a friction block and a support column, and using a threaded drive to drive the friction block to hold the sliding column. It achieves the technical effect of providing rigid auxiliary support, eliminating gaps and significantly improving the overall stability of the coffee table after the height is adjusted.

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-7 The present invention provides an embodiment of a lifting coffee table lifting component, comprising a housing 1 and a mounting base 2 slidably disposed inside the housing 1. The housing 1 serves as the support base for the entire component, with its bottom end used for stable placement on the ground or connection to a base. The mounting base 2 serves as a bearing platform, with its top end used for fixed connection to the coffee table surface. The outer wall of the mounting base 2 is in close contact with the inner wall of the housing 1 and slides vertically back and forth, thereby realizing the height adjustment of the coffee table. The housing 1 and the mounting base 2 are precisely slidably fitted together to form the main telescopic frame of the lifting component, providing a basic structural carrier for subsequent locking and auxiliary support.

[0033] It also includes an adjustment component 3, which is mainly located in the bottom area of ​​the outer casing 1. The adjustment component 3 includes a fixed base 302, a foot pedal 301, a rotating plate 303, a sliding block 305, a rising column 304, a sliding inner column 307, and an inclined block 308. The fixed base 302 is fixedly connected to the bottom outer wall or bottom structure of the outer casing 1. The middle or end of the foot pedal 301 is rotatably connected to the inside of the fixed base 302 via a pivot. One end of the foot pedal 301 extends to the outside of the fixed base 302 for the user to step on, and the other end extends into the fixed base 302 and is fixed. A rotating plate 303 is connected. The rotating plate 303 is elongated or other shapes suitable for plucking. It swings upward synchronously with the rotation of the foot pedal 301. The fixed base 302 has a groove or guide surface in the vertical direction. The sliding block 305 is limited to slide in the groove. The bottom surface of the sliding block 305 directly abuts or adheres to the outer wall surface of the rotating plate 303. When the rotating plate 303 swings upward, it can push the sliding block 305 to move upward in the vertical direction, thereby converting the rotational motion of the foot pedal 301 into the vertical linear motion of the sliding block 305.

[0034] Meanwhile, a rising column 304 is fixedly connected to the top of the sliding block 305. The rising column 304 extends vertically upward and passes through the side wall or bottom of the outer shell 1 to enter the interior of the outer shell 1. A sliding inner column 307 is fixedly connected to one end of the rising column 304 inside the outer shell 1. The sliding inner column 307 is slidably fitted into the inner cavity of the outer shell 1. An inclined block 308 is also installed inside the side wall of the outer shell 1. Multiple slots 306 are spaced vertically on the side wall of the mounting base 2. The end shape of the inclined block 308 is adapted to the slot 306 and is used to engage with the slot 306 to lock the installation. The height of the seat 2, the side wall of the sliding inner column 307 corresponding to the position of the inclined block 308 is provided with a slot for the inclined block 308 to pass through. The inclined block 308 has a force-bearing inclined surface. When the sliding inner column 307 slides upward with the rising column 304, the edge of the slot on the sliding inner column 307 will squeeze the force-bearing inclined surface of the inclined block 308. Using the inclined surface guiding principle, the inclined block 308 is forced to overcome the resistance and retract into the side wall of the outer shell 1, thereby disengaging from the slot 306 on the mounting seat 2 and realizing the unlocking function. This structure realizes the convenient operation of unlocking by stepping through a clever mechanical transmission chain.

[0035] In a preferred embodiment, in order to achieve automatic reset and reliable locking of the inclined block 308, a damper 309 is provided inside the housing 1 or between the inclined block 308 and the inner wall of the housing 1. One end of the damper 309 is fixed to the housing 1, and the other end is connected to the inclined block 308. The damper 309 is in a compressed or stretched state and continuously applies a pushing force or elastic force in the direction of the mounting seat 2 to the inclined block 308. This ensures that after the sliding inner column 307 resets and releases the pressure on the inclined block 308, the inclined block 308 can quickly pop out and lock into the corresponding slot 306. At the same time, the damper 309 can also buffer the impact force when the inclined block 308 pops out, thus extending the service life of the component.

[0036] As another preferred embodiment, to further improve the stability of the mounting base 2 after lifting and lowering, and to prevent the coffee table surface from wobbling, please refer to... Figure 1 The lifting assembly also includes a support assembly 4, which includes an outer wall ring 401 fixedly connected to the outer wall of the housing 1 and a sliding column 403 fixedly connected to the bottom of the mounting base 2. The sliding column 403 is parallel to the lifting direction of the mounting base 2 and slides through the internal hole of the outer wall ring 401. A receiving cavity is provided inside the side wall of the outer wall ring 401, and a friction block 402 is slidably installed in the receiving cavity. The side of the friction block 402 near the sliding column 403 has an arc-shaped contact surface that matches the shape of the sliding column 403. A threaded hole is provided on the outer wall of the outer wall ring 401 and a support column 404 is screwed on it. The end of the support column 404 extends into the receiving cavity and is rotatably connected to or abuts against the friction block 402. By rotating the support column 404, the friction block 402 is driven to move inward and press against the outer wall of the sliding column 403 using the threaded propulsion principle. This grips and fixes the sliding column 403 by friction, providing an additional lateral support point for the mounting base 2 and effectively eliminating the wobbling hazard caused by the fit clearance.

[0037] Working principle: When the user needs to adjust the height of the coffee table, he first presses down on the foot pedal 301, causing the foot pedal 301 to rotate inside the fixed base 302. During the rotation of the foot pedal 301, it will drive the rotating plate 303 connected to it to swing upward together. As the rotating plate 303 swings upward, its outer wall pushes the sliding block 305 to slide vertically upward under the limiting and guiding action of the fixed base 302, thereby converting the arc swing of the rotating plate 303 into the vertical upward movement of the sliding block 305.

[0038] The upward movement of the sliding block 305 drives the rising column 304 to slide upward synchronously, thereby pulling the inner sliding column 307 to move upward inside the outer shell 1. During the upward movement of the inner sliding column 307, the edge of the slot opened on its side wall will contact and squeeze the inclined surface of the inclined block 308. Through the inclined plane transmission principle, the vertical force is converted into a horizontal component force, forcing the inclined block 308 to retract into the side wall of the outer shell 1 and compress the damper 309. At this time, the inclined block 308 completely disengages from the slot 306 on the mounting base 2, the mounting base 2 is unlocked, and the user can freely adjust the height of the mounting base 2 and the coffee table surface.

[0039] After the mounting base 2 is adjusted to the specified height, the user releases the foot pedal 301. Under the weight of the sliding inner column 307 and the rising column 304, the sliding inner column 307 slides down to reset. When the slot on the sliding inner column 307 is aligned with a slot 306 on the mounting base 2 again, the inclined block 308 loses the squeezing restriction of the slot edge and quickly resets and pops out under the rebound force of the damper 309. It passes through the slot of the sliding inner column 307 and slides into the slot 306 of the mounting base 2, thereby relocking the mounting base 2 at the new height position. At the same time, as the sliding inner column 307 slides down to reset, the rising column 304 drives the sliding block 305 to press down the rotating plate 303, which in turn drives the foot pedal 301 to rotate in the opposite direction and reset to the initial top position for the next operation.

[0040] To further enhance stability after adjustment, the support component 4 must be used before and after height adjustment. Before adjusting the height, rotate the support column 404 outward to release the clamping limit on the friction block 402 by using the threaded release, so that the friction block 402 is in a relaxed state in the receiving cavity of the outer wall ring 401, allowing the sliding column 403 to slide freely in the outer wall ring 401 and follow the rise and fall of the mounting seat 2. After the height adjustment is completed and the mounting seat 2 is locked by the inclined block 308, rotate the support column 404 inward to tighten it. The support column 404 pushes the friction block 402 to fit tightly against the outer wall of the sliding column 403, using friction to provide auxiliary support and fixation for the sliding column 403, and share the pressure on the mounting seat 2, thereby making the lifting component more stable and reliable.
