Description

Technical Field

[0001] This utility model relates to the field of electric heated table technology, specifically an electric heated adjustable table. Background Technology

[0002] An electric heated table is a combination of an electric heater and a table, also known as an electric heated table. It is a new type of heating appliance that integrates a table and a heater. Based on the traditional table appearance, electric heated tables add a safe, flameless heating function, using far-infrared radiation and convection heating. They are mainly divided into several types: electric ceramic stove heated tables, electric heated coffee tables, electric heated dining tables, electric heated desks, and electric heated mahjong tables.

[0003] Chinese patent CN219845504U discloses a height-adjustable electric heating table. The device uses a structure with two support legs that slide together and are connected to each other. The height of the support leg is adjusted by controlling the rise and fall of the support leg relative to the support leg one through an electric telescopic device. In addition, the device has a heat-conducting plate wrapped around the heating layer, which makes the heat transmitted from the heating layer more even and improves the safety of use.

[0004] Based on the above-disclosed technical solutions and existing technologies, the current device does not have a large lifting range when it is raised or lowered. After the extension and retraction are completed, there is still a certain height above the ground, and the extension and retraction effect is not ideal. In addition, its table legs are fixed, which takes up a lot of space when transporting or storing it. Utility Model Content

The inside of the hollow lead screw is sleeved on the outside of the lead screw. Limit blocks are fixedly installed on both sides of the hollow lead screw, and limit grooves are opened on both sides of the lead screw. The limit blocks are slidably connected to the inside of the limit grooves. A lifting tube C is slidably connected to the inside of lifting tube B, and the lifting tube C is threadedly connected to the hollow lead screw.

[0008] As a further improvement to the above solution, a heating layer is fixedly installed on the bottom of the tabletop, and the heating layer has the same function and structure as the heating layer disclosed in CN219845504U.

[0009] As a further improvement to the above solution, the support component includes a base plate, with mounting grooves at each of the four corners of the base plate, and a baffle B fixedly installed on the top of the inner wall of the mounting groove. A telescopic plate A is slidably connected inside the mounting groove, and a baffle A is fixedly installed on the top of the inner wall of the telescopic plate A.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] This utility model provides, for example Figure 1-6 The electric heating lifting table shown includes a tabletop 1, with lifting components fixedly connected to both sides of the bottom of the tabletop 1, and a support component fixedly connected to the bottom of the lifting components. A heating layer 2 is fixedly installed on the bottom of the tabletop 1, and the heating layer 2 has the same functional structure as the heating layer disclosed in CN219845504U.

[0027] The lifting assembly controlling the height of the electric heating table includes a connecting rod 11 and two mounting tubes 16. A bevel gear set 12 is fixedly connected to both sides of the connecting rod 11. The bevel gear set 12 is located inside the mounting tubes 16 and consists of three meshing gears. Two bevel gears in the bevel gear set 12 are fixedly connected to lead screws 13. A motor 15 is fixedly mounted on the outside of the mounting tubes 16, with its output end fixedly connected to the connecting rod 11. The motor 15 can rotate in both directions. A protective shell 3 is fixedly installed on one side of the mounting tube 16. The motor 15 is located inside the protective shell 3. Lifting tubes A8 are fixedly connected to both ends of the mounting tube 16. Lifting tube B9 is slidably connected to the inside of the lifting tube A8. A nut block 17 is fixedly installed at one end of the inside of the lifting tube B9. The nut block 17 consists of a cylindrical tube and a cylindrical ring. The cylindrical ring is fixedly sleeved on the outside of the cylindrical tube. The turntable 21 has a rotating groove inside that matches the cylindrical ring, so that the turntable 21 rotates along the nut block and moves upward along with the lifting tube B9.

[0028] Nut block 17 is threadedly connected to lead screw 13. A matching turntable 21 is connected to the outside of nut block 17. A hollow lead screw 14 is fixedly connected through the axis of turntable 21. The inner side of hollow lead screw 14 is sleeved on the outside of lead screw 13. Limiting blocks 5 are fixedly installed on both sides of hollow lead screw 14. Limiting grooves 18 are opened on both sides of lead screw 13. Limiting blocks 5 are slidably connected to the inner side of limiting grooves 18, so that lead screw 13 can drive hollow lead screw 14 to rotate. Lifting tube B9 is slidably connected to lifting tube C10. A threaded hole matching hollow lead screw 14 is opened at the axis of lifting tube C10. Lifting tube C10 is threadedly connected to hollow lead screw 14 through threaded hole. Vertical grooves are opened on the inner side of lifting tube A8 and lifting tube B9. Vertical blocks matching vertical grooves are fixedly installed on the outer side of lifting tube B9 and lifting tube C10. Vertical blocks are slidably connected to the inner side of vertical grooves.

[0029] The support assembly for the electric heating table includes a base plate 4. Mounting slots are provided at each of the four corners of the base plate 4. A baffle B19 is fixedly installed on the top of the inner wall of each mounting slot. A telescopic plate A6 is slidably connected inside the mounting slot. A baffle A20 is fixedly installed on the top of the inner wall of the telescopic plate A6. A telescopic plate B7 is slidably connected inside the telescopic plate A6. Limiting plates are fixedly installed on one side of the top of both the telescopic plates A6 and B7. Therefore, when operating the support assembly, there is no need to worry about pulling out the telescopic plates, as the limiting plates will restrict their movement.

[0030] The implementation principle of an electric heating lift table in this embodiment is as follows: After the electric heating lift table is placed using the support assembly, the motor 15 is started. The motor 15 drives the bevel gear set 12 to rotate through the connecting rod 11. The bevel gear set 12 drives the lead screw 13 and the hollow lead screw 14 to rotate. The lead screw 13 and the hollow lead screw 14 respectively drive the lifting tube B9 and the lifting tube C10, which are threaded to them, to slide upward. When the electric heating lift table rises to the specified height, the motor 15 is stopped. When it is necessary to adjust the electric heating lift table, the motor 15 is controlled to rotate in both directions to achieve the purpose of adjusting the height.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
