Description

Technical Field

[0001] This utility model relates to the field of conference table technology, and more specifically to an expandable conference table. Background Technology

[0002] A conference table is a piece of furniture specifically designed for meetings and events, typically placed in meeting rooms and similar venues. It generally features a large, relatively flat tabletop, facilitating seating for participants. Meeting documents, materials, laptops, water glasses, and other items can be placed on the table to meet the needs of communication, note-taking, and presentations during the meeting. Conference tables come in various shapes, commonly including rectangular, round, oval, square, and polygonal, and are made from a variety of materials such as solid wood, engineered wood, and metal. Different shapes and materials can suit meeting rooms of different styles, sizes, and functions.

[0003] Under current technological conditions, most extendable conference tables expand their tabletop area by splicing panels. Specifically, when there's a need to extend the tabletop, a common practice is to install metal connectors such as hinges and latches under the tabletop, then sequentially splice multiple square tabletops along their edges to form a large rectangular or other shaped conference table. Alternatively, some conference tables have pre-installed interfaces along the edges of the main table; when expansion is needed, the additional tabletop panels are moved over, aligned with the interfaces, and then spliced ​​and secured. Modular conference table systems often utilize this method. However, these existing... Some expansion methods have limitations. They often only focus on expanding the tabletop itself, while the supporting structure of the conference table remains unchanged. This leads to a decrease in overall stability. Furthermore, each time an expansion or contraction operation is required, the operator needs to spend considerable effort to precisely align the various tabletop panels, install connectors, or insert the panels into interfaces. Especially when facing large-scale assembly tasks, the entire process is not only cumbersome but also time-consuming. As a result, if there is an urgent need to use the expanded conference table, the excessive time spent on assembly may delay the start of the meeting. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an expandable conference table to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an expandable conference table, comprising four table legs, crossbars fixedly connected to the sides of the table legs, and a tabletop fixedly connected to the top of the table legs. An aluminum alloy sealing tube is fixedly connected to the side of the crossbar. An aluminum alloy fixing column is slidably connected inside the aluminum alloy sealing tube. A sealing box is fixedly connected to the top of the aluminum alloy sealing tube. A support column is slidably connected inside the sealing box. An exhaust hole is provided on the upper surface of the sealing box. An extension plate is fixedly connected to the end of the support column away from the sealing box. A movable component is installed inside the table legs.

[0006] Furthermore, the movable component includes a fixed bearing fixedly installed inside the table leg, a rotating rod fixedly connected to the inner ring of the fixed bearing, a driving bevel gear fixedly connected to the end face of the rotating rod, a driven bevel gear meshing with the surface of the driving bevel gear, a threaded rod fixedly connected to the inner center of the driven bevel gear, a positioning bearing fixedly installed on the outer surface of the threaded rod, a sliding plate slidably connected longitudinally inside the table leg, a roller rotatably connected inside the sliding plate, a limit rod inserted inside the sliding plate, and the threaded rod rotatably threadedly connected to the inner center of the sliding plate on its outer surface.

[0007] Furthermore, there are two crossbars and two desktops. One of them has grooves on both sides of the crossbar and the side of the extension plate, and the other desktop has protrusions fixedly connected to both sides of the extension plate. The opposite sides of the two desktops match the two sides of the extension plate.

[0008] Furthermore, the length of the aluminum alloy fixing post near the aluminum alloy sealing tube is greater than the length of the other end, and a sealing ring is fixedly installed on the outer surface of the aluminum alloy fixing post. The inner end of the aluminum alloy sealing tube near the aluminum alloy fixing post is connected to the interior of the sealing box. A vent hole is opened on the surface of the aluminum alloy sealing tube away from the aluminum alloy fixing post. The sliding length of the aluminum alloy fixing post is equal to the length of the extension plate.

[0009] Furthermore, the top of the inner part of the sealed box is connected to the outside of the sealed box through an exhaust hole, the bottom width of the support column is greater than the top width, and a sealing ring is fixedly installed on the outer surface of the support column.

[0010] Furthermore, the end of the rotating rod away from the driving bevel gear extends to the outside of the table leg, the bottom of the roller extends to the lower surface of the sliding plate, a threaded hole matching the threaded rod is opened at the center of the sliding plate, a limiting hole matching the limiting rod is opened inside the sliding plate, a limiting groove matching the sliding plate is opened inside the table leg, and the bottom of the limiting groove extends to the lower surface of the table leg.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, by pulling the crossbar, can drive the aluminum alloy fixed column to slide and pressurize the inside of the sealed box. The support column drives the extension plate to slide automatically upward. When the aluminum alloy fixed column is pulled to its limit length, the gap between the two tabletops is exactly matched with the extension plate. At the same time, the two sides of the extension plate are in contact with the opposite surfaces of the two tabletops. At this time, the tabletops and extension plates are spliced ​​together, and the conference table is extended. Furthermore, the interlocking between the grooves and protrusions improves the stability of the conference table after extension. By expanding or contracting, it can be well adapted to different scenarios, improving the space utilization efficiency of the conference room and its adaptability to various meeting formats.

[0013] 2. This utility model, by setting up movable components, allows the rollers of the four movable components to be adjusted to contact the ground, which facilitates the overall movement of the conference table. By adjusting the rollers of the two movable components on one side to contact the ground, the friction between the table legs and the ground can be reduced when the crossbar is dragged during the expansion of the conference table, thus protecting the office floor and making the expansion and adjustment of the conference table more effortless.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] Specifically, an expandable conference table includes four table legs 1, crossbars 2 fixedly connected to the sides of the table legs 1, and a tabletop 3 fixedly connected to the top of the table legs 1. An aluminum alloy sealing tube 4 is fixedly connected to the side of the crossbar 2. An aluminum alloy fixing column 5 is slidably connected inside the aluminum alloy sealing tube 4. A sealing box 6 is fixedly connected to the top of the aluminum alloy sealing tube 4. A support column 7 is slidably connected inside the sealing box 6. An exhaust hole 8 is opened on the upper surface of the sealing box 6. An extension plate 9 is fixedly connected to the end of the support column 7 away from the sealing box 6. A movable component 12 is installed inside the table legs 1.

[0023] In this implementation scheme, by pulling the crossbar 2, the aluminum alloy fixing column 5 can be slid and the internal pressure of the sealed box 6 can be increased. The support column 7 drives the extension plate 9 to slide automatically upward. When the aluminum alloy fixing column 5 is pulled to its limit length, the gap between the two tabletops 3 is exactly matched with the extension plate 9. At the same time, the two sides of the extension plate 9 are in contact with the opposite surfaces of the two tabletops 3. At this time, the tabletops 3 and the extension plate 9 are spliced ​​together, and the conference table is extended. By expanding or contracting, it can be well adapted to the corresponding scenario, improving the space utilization efficiency of the conference room and its adaptability to various conference formats.

[0024] Specifically, the moving component 12 includes a fixed bearing 121 fixedly installed inside the table leg 1. A rotating rod 122 is fixedly connected to the inner ring of the fixed bearing 121. A driving bevel gear 123 is fixedly connected to the end face of the rotating rod 122. A driven bevel gear 124 is meshed with the surface of the driving bevel gear 123. A threaded rod 125 is fixedly connected to the inner center of the driven bevel gear 124. A positioning bearing 126 is fixedly installed on the outer surface of the threaded rod 125. A sliding plate 127 is longitudinally slidably connected inside the table leg 1. A roller 128 is rotatably connected inside the sliding plate 127. A limit rod 129 is inserted inside the sliding plate 127. The outer surface of the threaded rod 125 is rotatably threadedly connected to the inner center of the sliding plate 127.

[0025] In this embodiment, by setting the movable components 12, the rollers 128 of the four movable components 12 can be adjusted to contact the ground, which facilitates the overall movement of the conference table. By adjusting the rollers 128 of the two movable components 12 on one side to contact the ground, the friction between the table legs 1 and the ground can be reduced when the conference table is extended, thus protecting the office floor and making the extension and adjustment of the conference table more effortless.

[0026] Specifically, there are two crossbars 2 and two desktops 3. One of the desktops 3 has a groove 10 on one side and the other side of the extension plate 9. The other desktop 3 has a protrusion 11 fixedly connected to the other side of the extension plate 9. The opposite sides of the two desktops 3 match the two sides of the extension plate 9.

[0027] In this embodiment, the interlocking between the grooves 10 and the protrusions 11 improves the stability between the extended tabletop 3 and the extension plate 9 after the conference table is extended.

[0028] Specifically, the length of the aluminum alloy fixing post 5 near the aluminum alloy sealing tube 4 is greater than the length of the other end, and a sealing ring is fixedly installed on the outer surface of the aluminum alloy fixing post 5. The inner end of the aluminum alloy sealing tube 4 near the aluminum alloy fixing post 5 is connected to the inside of the sealing box 6. A vent hole is opened on the surface of the aluminum alloy sealing tube 4 away from the aluminum alloy fixing post 5. The sliding length of the aluminum alloy fixing post 5 is equal to the length of the extension plate 9.

[0029] In this embodiment, by providing a vent hole, the aluminum alloy fixing column 5 can slide smoothly inside the aluminum alloy sealing tube 4.

[0030] Specifically, the top of the interior of the sealing box 6 is connected to the exterior of the sealing box 6 through the vent 8, the bottom width of the support column 7 is greater than the top width, and a sealing ring is fixedly installed on the outer surface of the support column 7.

[0031] In this embodiment, by providing an exhaust port 8, the air at the top of the sealed box 6 can be discharged when the support column 7 slides upward, allowing the support column 7 to slide smoothly.

[0032] Specifically, the end of the rotating rod 122 away from the drive bevel gear 123 extends to the outside of the table leg 1, the bottom of the roller 128 extends to the lower surface of the sliding plate 127, a threaded hole matching the threaded rod 125 is opened at the center of the sliding plate 127, a limiting hole matching the limiting rod 129 is opened inside the sliding plate 127, a limiting groove matching the sliding plate 127 is opened inside the table leg 1, and the bottom of the limiting groove extends to the lower surface of the table leg 1.

[0033] In this embodiment, the longitudinal sliding of the sliding plate 127 can be limited by setting the limiting rod 129.

[0034] The working principle and usage of this utility model are as follows: When the conference table needs to be extended, the rollers 128 in the two movable components 12 on one side are adjusted to contact the ground. During adjustment, the rotating rod 122 is rotated, which drives the driven bevel gear 124 to rotate via the driving bevel gear 123. The driven bevel gear 124 drives the threaded rod 125 to rotate. Through the engagement of the threaded rod 125 with the sliding plate 127, the sliding plate 127 is driven to slide downwards until the bottom of the rollers 128 touches the ground. At this time, by pulling the crossbar 2, the aluminum alloy fixed column 5 can be moved to slide. The mechanism moves and pressurizes the interior of the sealed box 6, causing the extension plate 9 to slide automatically upwards via the support column 7. When the aluminum alloy fixing column 5 is pulled to its maximum length, the gap between the two tabletops 3 matches the extension plate 9, and the two sides of the extension plate 9 fit against the opposite surfaces of the two tabletops 3. At this point, the tabletops 3 and the extension plate 9 are joined together, and the conference table is extended. The interlocking between the grooves 10 and the protrusions 11 improves the stability of the conference table after extension. By expanding or contracting, it can adapt well to different scenarios, improving the space utilization efficiency of the conference room and its adaptability to various meeting formats.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
