Description

Technical Field

[0001] This utility model relates to the technical field of household heating appliances, specifically to a table top-out structure and a liftable heating table having the structure. Background Technology

[0002] Existing height-adjustable heating tables use lifting nuts to push out casters. For example, a height-adjustable electric heating table disclosed in Chinese Patent No. ZL202320533374.4 includes a panel, a lifting column assembly, a fixed column, and a foot box. The panel is fixedly connected to the upper end of the lifting column assembly, and the foot box is fixedly connected to the lower part of the fixed column. The lifting column assembly is slidably disposed in the fixed column and drives the panel to rise and fall. The lifting column assembly is provided with a lifting internal thread hole and a screw threadedly connected to it. The foot box is provided with a motor, a transmission rod, and a gearbox. The screw is connected to the gearbox for transmission. A telescopic frame is movably disposed below the lifting column assembly. Guide holes are provided on the lower periphery of the screw and the periphery of the gearbox. The telescopic frame is slidably disposed in the guide holes. The telescopic frame is provided with a caster device, which is slidably disposed in the lower part of the fixed column or the bottom of the foot box. When in use, the table is placed stably on the ground. As the four lifting nuts descend, pressing down on the four downward-pressing positions and pulling down the four telescopic frames, the four telescopic frames drive the four caster mechanisms to extend downwards from the bottom of the fixed column or the base box. The lifting nuts move axially and press down on the casters when the screw rotates, triggering the caster mechanisms to extend downwards beyond the heated table, resulting in low transmission efficiency. Furthermore, a return spring is required to lift the telescopic frames upwards, allowing the telescopic frames and caster mechanisms to retract upwards into the fixed column or base box. Utility Model Content

[0003] This utility model proposes a table ejection structure and its lifting heating table. Its transmission structure is simple. Due to the nut sleeve fixing, the screw rotates and moves up and down axially at the same time, triggering the ejection component at the bottom of the heating table to extend and retract. It has high transmission efficiency, simple structure and short transmission stroke.

[0004] A table ejection structure designed for this purpose includes a screw installed in a support assembly and a drive device for moving the screw up and down.

[0005] The upper part of the support component is provided with a desktop component, and the lower part of the support component is provided with a push-out component;

[0006] During the up-and-down movement of the screw, the ejected component extends downwards into the support component or retracts upwards into the support component.

[0007] The ejected component is a set of movable wheels, which extends downwards to support the component, allowing the entire table to move via the movable wheels.

[0008] The movable wheel assembly includes a wheel frame, on which a first guide member is provided. The wheel frame extends downward into the support assembly or retracts upward into the support assembly via the first guide member.

[0009] The bottom of the wheel frame is equipped with rotating rollers.

[0010] The ejected component is a support leg. The support leg extends downwards from the support component, and the table as a whole is relatively raised to adjust the distance between the lower part of the table's support component and the ground.

[0011] The desktop component has a base underneath, which is connected to the support component. The component that is pushed out serves as a support leg, and the support leg extends downwards from the support component to raise the base relative to the ground.

[0012] The support leg is provided with a second guide. During the movement of the screw, the support leg extends downward into the support assembly or retracts upward into the support assembly through the second guide.

[0013] The bottom of the support leg is equipped with a soft cushioning pad.

[0014] The drive device is disposed between the desktop component and the support component;

[0015] Alternatively, a base connected to a support component is provided below the desktop component, and the drive device is disposed within the base.

[0016] The drive device includes a nut sleeve that mates with the screw, and a power assembly that is connected to the screw drive.

[0017] The nut is fixed inside the support assembly. After the power assembly is started, the screw moves up and down.

[0018] The support assembly includes a fixed rod, a nut sleeve located inside the fixed rod and fixedly connected to the fixed rod, a screw inserted into the nut sleeve, and a fixed rod located outside the screw.

[0019] The drive device also includes a synchronizing rod and a gearbox. Support components are provided at the four corners of the table. The end of the screw is inserted into the corresponding gearbox and is connected to the corresponding gearbox in a transmission manner. The end of the synchronizing rod is inserted into the corresponding gearbox and is connected to the corresponding gearbox in a transmission manner. The screws of each support component are connected to the gearbox in a synchronous transmission manner through the synchronizing rod.

[0020] The support assembly includes a column, a movable seat at the top of the column, a guide opening for inserting the movable seat, a fixing rod inside the column, and at least a portion of the movable seat is inserted into the column along the guide opening.

[0021] The gearbox is fixedly mounted on the movable seat. When the screw moves up and down, the gearbox and the movable seat move up and down with the screw.

[0022] The column is fixed on the base, and the base is provided with a connecting plate that is fixedly connected to the fixing rod; the ejected component is provided with a guide structure, and the connecting plate is provided with a guide hole that cooperates with the guide structure. The ejected component moves up and down in the lower part of the support component through the guide hole and the guide structure.

[0023] A height-adjustable heating table includes a heating table body with the aforementioned table top-out structure. The support assembly includes a column with a mounting cavity for installing a heating element and a heating vent on the outer surface of the column that connects the mounting cavity to the outside air.

[0024] The beneficial technical effects of this utility model are as follows:

[0025] With the above technical features, the transmission structure of the heating table is simple. Because the nut sleeve is fixed, the screw rotates and moves up and down axially at the same time, triggering the pushed-out component at the bottom of the heating table to extend and retract. The transmission efficiency is high, the structure is simple, and the transmission stroke is short.

[0026] Setting the ejected component as a moving wheel assembly or supporting high feet has the following technical effects:

[0027] When the table needs to be moved, the casters extend downwards into the support assembly. When the table does not need to be moved, the casters retract upwards into the support assembly, effectively preventing the table from moving unnecessarily when it is not in use.

[0028] The support legs extend downwards to raise the base relative to the ground. Once the base is raised, it is easier for a robot vacuum cleaner or cleaning tools (such as a broom and mop) to enter between the base 13 and the ground to clean the bottom surface beneath the base.
