Description

Technical Field

[0001] The utility model relates to the technical field of tea tables, in particular to a lifting tea table. Background Art

[0002] A coffee table is a piece of furniture used to place tea sets, typically in square or rectangular shapes. It's smaller than a desk and about the same height as an armrest. Typically, it's placed between two chairs, used to hold cups, plates, and tea utensils, hence the name. With technological advancements, traditional coffee tables are no longer able to meet the growing demands of users, leading to the emergence of electronic coffee tables. These typically feature a lift function.

[0003] However, the current coffee table has a short travel range and cannot meet the needs of users when they need to lower it or raise it higher. It only has a single coffee table function and cannot meet customer needs. In addition, the height of traditional coffee tables is relatively high and does not meet the size requirements of today's urban homes. Due to its large size, the shipping and packaging costs are also higher. Utility Model Content

In addition, the height of traditional coffee tables is relatively high and does not meet the size requirements of current urban homes. Due to its large size, the shipping and packaging costs are also higher.

[0005] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0006] The lifting mechanism is a pair of fixedly mounted on two ends of the lifting link, and the fixing mechanism is a pair of fixedly mounted on two ends of the lifting link, and the fixing mechanism is a pair of fixedly mounted on two ends of the lifting link.

[0007] The outer column is used to support the coffee table and has a first slide groove. The first slide groove is used to accommodate the middle column and provide a channel for the middle column to slide. The lifting sleeve is used to install the lifting nut a so that the lifting screw a can move up and down inside. The lifting nut a is used to enable the lifting screw a to rotate inside. The middle column is used to support the coffee table and has a second slide groove. The second slide groove is used to accommodate the inner column and provide a channel for the inner column to slide. The sliding guide a is used to prevent the middle column from disengaging from the first slide groove. The inner column is used to support the coffee table. The sliding guide b is used to prevent the inner column from disengaging from the second slide groove. The lifting screw a is used to accommodate the lifting screw b and move linearly in the lifting sleeve. The second threaded sleeve is used to enable the lifting screw b to rotate inside. The drive assembly is used to drive the lifting screw b to rotate. The coffee table top is used as the main body of the coffee table.

[0008] As a preferred solution of a lifting coffee table described in the utility model, wherein: a limiting slide groove is opened inside the lifting screw a, a screw linkage key is installed at the bottom end of the lifting screw b, and the screw linkage key is vertically movably connected to the limiting slide groove; the limiting slide groove is used to provide a channel for the screw linkage key to slide, and the screw linkage key is used to move in a straight line vertically along the limiting slide groove to prevent the lifting screw b from rotating inside the lifting screw a.

[0009] As a preferred solution of a lifting coffee table described in the utility model, wherein: the driving assembly includes a driving motor, a transmission shaft, a first bevel gear and a second bevel gear, the transmission shaft is connected to the output end of the driving motor, the two first bevel gears are mirror-mounted at both ends of the transmission shaft, the top end of the second bevel gear is vertically movably connected to the bottom end of the first bevel gear, and the top end of the lifting screw b is connected to the bottom end of the second bevel gear; the driving motor is used to drive the transmission shaft to rotate, the transmission shaft is used to drive the first bevel gear to rotate, the first bevel gear is used to drive the second bevel gear to rotate, and the second bevel gear is used to drive the lifting screw b to rotate.

[0010] As a preferred solution of a lifting coffee table described in the utility model, a gear box is provided on the outside of the first bevel gear and the second bevel gear, and the four gear boxes are respectively installed at the four inner corners of the coffee table top; the gear box is used to accommodate and install the first bevel gear and the second bevel gear.

[0011] As a preferred solution of a liftable coffee table described in the utility model, heaters are installed on the four inner sides of the coffee table top, and a heat dissipation port is opened at the bottom end of the heater; the heater is used to provide heating function for the coffee table top, and the heat dissipation port is used to provide heat dissipation function.

[0012] As a preferred solution of a lifting coffee table described in the utility model, a ventilation hole is opened at the middle bottom end of the coffee table surface; the ventilation hole is used to allow air to flow inside and outside the coffee table surface to prevent the humidity inside the coffee table surface from being too high.

[0013] As a preferred solution of a lifting coffee table described in the utility model, wherein: two adjacent outer columns below the coffee table table top are connected by a connecting frame, and anti-slip pads are installed on both sides of the bottom end of the connecting frame; the connecting frame is used to connect the two outer columns on one side to increase the structural strength.

[0015] The beneficial effects of the utility model are as follows: when the height needs to be adjusted, the driving assembly drives the lifting screw b to rotate. Since the lifting screw b slides vertically in the lifting screw a, it can drive the lifting screw a to rotate. The lifting screw a rotates on the lifting nut a, so that the lifting screw a moves upward along the lifting sleeve, driving the middle column to move upward along the first sliding groove. When it moves to the extreme position, the sliding guide a blocks the further movement of the middle column, making it impossible for the lifting screw a to move further. The lifting screw b moves upward along the lifting screw a, driving the inner column to move upward along the second sliding groove.

[0016] The liftable coffee table has a two-stage lifting function and a larger lifting range. It can be used as a coffee table when lowered and as a dining table when raised. Therefore, it meets the needs of users very well. Moreover, the height is shorter when folded, which is more in line with the size requirements of urban residents for homes. At the same time, due to its smaller size, it can increase the transportation quantity, reduce freight, and save packaging costs. BRIEF DESCRIPTION OF THE DRAWINGS
