Description

Technical Field

[0001] This utility model relates to the field of electric table technology, and in particular to a folding electric small table. Background Technology

[0002] Small studio apartments have relatively limited dining space, so it's necessary to reserve 3 square meters for a dining table to accommodate 2-4 people. At the same time, the distance between the dining table and the wall or furniture needs to be more than 1 meter to facilitate entry and exit during meals. If the dining area is small but the dining table is relatively large, people usually choose a foldable dining table to save space. However, existing foldable electric tables generally have the problem of taking up a lot of space on the tabletop.

[0003] For example, Chinese utility model patent CN209003069U discloses an electric folding table. Although this solution has the advantages of convenient use and easy operation, the swing arm is connected to the support arm through a connecting rod, and the swing arm is driven to rotate by a driver. During the rotation, the support arm is extended or retracted through the connecting rod to change the support state of the support arm on the tabletop. However, this type of electric folding table mainly reduces the space occupied by folding the table legs. However, the fixed part of the tabletop remains unchanged. When the number of people sitting around the table increases, the tabletop cannot be effectively accommodated. When the number of people sitting around the table is small and a large tabletop area is not required, the tabletop of this table has the problem of occupying a lot of space.

[0004] In view of this, a folding electric small table is proposed that can solve the above problems. Utility Model Content

[0005] To address the technical problem of large tabletop space occupied by electric folding tables, this utility model provides a folding electric small table.

[0006] This utility model is achieved using the following technical solution: a folding electric small table, including a table frame, a load-bearing beam fixedly connected to the upper side of the table frame, a driven gear rotatably connected to the upper side of the load-bearing beam, a plurality of sliding rods slidably connected to the driven gear, a central tabletop fixedly connected to the upper ends of the plurality of sliding rods, sleeves fixedly connected to the upper two sides of the table frame, a sliding plate slidably connected to the inner sides of both ends of each sleeve, an extended tabletop fixedly connected to one end of the two sliding plates on each side, the two extended tabletops cooperating with the central tabletop, a tabletop lifting mechanism for moving the central tabletop up and down provided on the upper side of the driven gear, and a tabletop folding mechanism for moving the two extended tabletops closer to or further apart provided on the upper side of the load-bearing beam.

[0007] As a further improvement to the above solution, the desktop lifting mechanism includes an outer limiting cylinder fixedly connected to the upper side of the load-bearing beam. The outer side of the outer limiting cylinder is rotatably connected to the inner side of the driven gear. An inner limiting cylinder is fixedly connected to the inner side of the outer limiting cylinder. A pointer lifting mechanism is provided on both the outer limiting cylinder and the inner limiting cylinder.

[0008] As a further improvement to the above solution, the pointer raising and lowering mechanism includes an outer annular groove opened inside the outer limiting cylinder, an outer pointer rod slidably connected to the inner side of the outer annular groove, an inner annular groove opened inside the inner limiting cylinder, an inner pointer rod slidably connected to the inner side of the inner annular groove, the upper ends of the outer pointer rod and the inner pointer rod are fixedly connected to the lower side of the central table, and a gear drive mechanism for rotating the driven gear is provided on the lower side of the load-bearing beam.

[0009] As a further improvement to the above solution, the gear drive mechanism includes a drive gear rotatably connected to the upper side of the load-bearing beam, the drive gear meshing with the driven gear, and a servo motor mounted on the lower side of the load-bearing beam, the output end of the servo motor being connected to the lower side of the drive gear.

[0010] As a further improvement to the above solution, the desktop folding mechanism includes limiting plates that are fixedly connected to both sides of the load-bearing beam. Each limiting plate has a toothed plate slidably connected to the side of the driven gear. Each toothed plate meshes with one side of the driven gear. The end of each toothed plate away from the driven gear is fixedly connected to the underside of the extended desktop on the same side.

[0011] As a further improvement to the above solution, a switch panel is installed on the lower side of the central desktop, and the switch panel is electrically connected to the servo motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses an active gear to drive a driven gear to rotate. When the outer pointer rod and the inner pointer rod on the lower side of the central tabletop are respectively located on the concave track section of the outer annular groove and the inner annular groove, the central tabletop descends and is joined together with the extended tabletops on both sides to form a complete new tabletop. When the outer pointer rod and the inner pointer rod are respectively located on the high track section of the outer annular groove and the inner annular groove, the outer pointer rod and the inner pointer rod lift the central tabletop upward, while the extended tabletops on both sides are pulled back to the lower side of the central tabletop, thereby realizing the function of adjusting the length of the tabletop according to specific circumstances.

[0014] 2. This utility model uses the rotation of the driven gear to push the toothed plates on both sides to slide, thereby pulling the extended tabletops on both sides back inward to below the central tabletop, thus reducing the space occupied by the electric tabletop and freeing up more usable space in the restaurant.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figures 1-3 This embodiment of a folding electric small table includes a table frame 1. Please refer to... Figure 3 As shown, in this utility model, the upper side of the table frame 1 is a square frame structure, and the lower side is equipped with 4 support legs;

[0026] Please combine Figure 3 As shown, a load-bearing beam 7 is fixedly connected to the upper side of the table frame 1, and a driven gear 11 is rotatably connected to the upper side of the load-bearing beam 7. In this embodiment, two sliding rods 9 are slidably connected to the driven gear 11. During the process of the central tabletop 3 rising and falling, the sliding rods 9 can slide up and down along the driven gear 11.

[0027] Please combine Figure 2 and Figure 3 As shown, the upper ends of the two sliding rods 9 are fixedly connected to the central desktop 3. The upper sides of the table frame 1 are respectively fixedly connected to the sleeves 13. The sleeves 13 are hollow structures. The inner sides of both ends of each sleeve 13 are slidably connected to the slide plates 5. The slide plates 5 have strong shear resistance and are used to support the extended desktops 2 on both sides.

[0028] Please combine Figure 3 As shown, one end of each of the two slide plates 5 is fixedly connected to an extended tabletop 2. The two extended tabletops 2 are configured to cooperate with the central tabletop 3. A tabletop lifting mechanism that moves the central tabletop 3 up and down is provided on the upper side of the driven gear 11. A tabletop folding mechanism that moves the two extended tabletops 2 closer to or further away from each other is provided on the upper side of the load-bearing beam 7.

[0029] Please combine Figure 5 As shown, the tabletop lifting mechanism includes an outer limiting cylinder 17 fixedly connected to the upper side of the load-bearing beam 7. The outer side of the outer limiting cylinder 17 is rotatably connected to the inner side of the driven gear 11. An inner limiting cylinder 16 is fixedly connected to the inner side of the outer limiting cylinder 17. Both the outer limiting cylinder 17 and the inner limiting cylinder 16 are equipped with pointer lifting mechanisms.

[0030] Please combine Figure 6 As shown, the pointer lifting and lowering mechanism includes an outer annular groove 19 opened inside the outer limiting cylinder 17, an outer pointer rod 18 is slidably connected to the inner side of the outer annular groove 19, and an inner annular groove 15 is opened inside the inner limiting cylinder 16. It should be noted that both the outer annular groove 19 and the inner annular groove 15 are provided with a grooved track section with peaks and valleys and a horizontal high-position track section.

[0031] Please combine Figure 6 As shown, an inner pointer rod 14 is slidably connected to the inner side of the inner annular groove 15, and the upper ends of the outer pointer rod 18 and the inner pointer rod 14 are fixedly connected to the lower side of the central tabletop 3. A gear drive mechanism for rotating the driven gear 11 is provided on the lower side of the load-bearing beam 7.

[0032] The outer pointer rod 18 and the inner pointer rod 14 are set on a straight line, and each side can be rotated 180 degrees. After each side is rotated 180 degrees, the outer pointer rod 18 and the inner pointer rod 14 are simultaneously in the groove track section or simultaneously in the high track section.

[0033] When the outer pointer rod 18 and the inner pointer rod 14 are simultaneously located in the groove track section, the height of the central tabletop 3 decreases to match that of the two sides, and the state is the extended state.

[0034] When the outer pointer rod 18 and the inner pointer rod 14 are both in the high-position track section, the height of the central tabletop 3 rises, and the central tabletop 3 is located above the two extended tabletops 2, in a folded and retracted state.

[0035] Please combine Figure 2 and Figure 3 As shown, the gear drive mechanism includes a drive gear 10 rotatably connected to the upper side of the load-bearing beam 7. The drive gear 10 meshes with the driven gear 11. A servo motor 8 is mounted on the lower side of the load-bearing beam 7. The output end of the servo motor 8 is connected to the lower side of the drive gear 10.

[0036] Please combine Figure 3 As shown, the desktop folding mechanism includes limiting plates 12 that are fixedly connected to both sides of the load-bearing beam 7. Each limiting plate 12 has a toothed plate 6 slidably connected to the side of the driven gear 11. Each toothed plate 6 meshes with one side of the driven gear 11. The end of each toothed plate 6 away from the driven gear 11 is fixedly connected to the lower side of the extended desktop 2 on the same side.

[0037] Please combine Figure 2 As shown, a switch panel 4 is installed on the lower side of the central desktop 3. The switch panel 4 is electrically connected to the servo motor 8, and buttons are provided on the switch panel 4.

[0038] The implementation principle of a folding electric small table in this application embodiment is as follows: when the number of people sitting around increases and it is necessary to expand the extension distance of the electric table, the servo motor 8 is started through the switch panel 4, which drives the active gear 10 to rotate and pushes the driven gear 11 to rotate. The driven gear 11 drives the central tabletop 3 to rotate through two slide rods 9. At the same time, the driven gear 11 pushes the toothed plates 6 on both sides to slide outward along the limiting plate 12, and drives the sliding plates 5 on both sides to slide outward along the inner side of the sleeve 13, thereby pushing the extended tabletop 2 on both sides to extend outward.

[0039] When the central tabletop 3 rotates, the outer pointer rod 18 and the inner pointer rod 14, which are fixedly connected below the central tabletop 3, rotate from the high-position track of the outer annular groove 19 and the inner annular groove 15 to the concave bottom track section. The change in the pointer height of the outer pointer rod 18 and the inner pointer rod 14 directly pushes the central tabletop 3 to descend, so that the extended central tabletop 3 is consistent with the extended tabletops 2 on both sides.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
