[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 As shown, a telescopic conference table includes a support frame 1. A tabletop 2 is slidably connected to both sides of the top of the support frame 1. Folding table panels 3 are rotatably connected to both sides of the top of the tabletop 2. The folding table panels 3 are hinged to the tabletop 2 via hidden hinges. This design ensures that the hinges do not protrude when the folding table panels 3 are unfolded on the tabletop 2. Both tabletops 2 are of the same size, and the folding table panels 3 on top of both tabletops 2 are also of the same size. By ensuring that the tabletops 2 and folding table panels 3 are of the same size, the tabletops 2 are symmetrical after extension and retraction, thus ensuring that the folding table panels 3 can be flipped up smoothly. The table surface is flat. Both sides of the bottom of the tabletop 2 are equipped with a fixing structure 4 to support the folded tabletop 3 after it is flipped. The fixing structure 4 includes fixing blocks 41 fixed to both sides of the bottom of the tabletop 2. The inner side of the fixing block 41 is provided with a sliding groove 43. The inner side of the sliding groove 43 is slidably connected to the fixing frame 42. Through the setting of the fixing structure 4, the fixing frame 42 can be pulled to slide in the sliding groove 43 on the inner side of the fixing block 41, thereby supporting the folded tabletop 3. The inner side of the support frame 1 is equipped with a telescopic structure 6, and the inner side of the support frame 1 is provided with a lubrication structure 5 that works in conjunction with the telescopic structure 6.

[0026] The lubrication structure 5 includes a support plate 51 fixedly connected inside the support frame 1. An oil tank 55 is fixedly connected to the top of the support plate 51, and a piston assembly 52 is installed inside the oil tank 55. A one-way valve 53 is installed on one side of the oil tank 55, and the one-way valve 53 is made of a composite sealing material such as PTFE + metal. An oil pipe 54 is connected to the other side of the one-way valve 53. Through the lubrication structure 5, the gear 2 62 can be lubricated during the extension and retraction of the tabletop 2, so that the gear plate 1 63 and gear plate 2 64 can be lubricated at the same time during the rotation. This effectively reduces the jamming phenomenon during the extension and retraction process and improves the smoothness of the tabletop 2 pushing and pulling.

[0027] The piston assembly 52 includes a piston plate 521 movably connected inside the oil tank 55. A sealing strip 522 is fixedly connected to the surface of the piston plate 521. A piston rod 523 is fixedly connected to the top of the piston plate 521. A rotating block 524 is rotatably connected to the top of the piston rod 523. A swing rod 525 is rotatably connected to the other end of the rotating block 524. A gear 526 is rotatably connected to the other end of the swing rod 525. Through the setting of the piston assembly 52, during the extension and retraction of the tabletop 2, the gear 526 is driven to rotate. The swing rod 525 and the piston rod 523 drive the piston plate 521 to move inside the oil tank 55, thereby dripping lubricating oil onto the surface of the gear 62 through the one-way valve 53 and the oil pipe 54. This can achieve automatic lubrication of the gear 62.

[0028] The telescopic structure 6 includes a horizontal plate 66 fixedly connected to the bottom inner side of the support frame 1. A transmission rod 61 is rotatably connected inside the horizontal plate 66. A gear 65 is fixedly connected to the middle of the transmission rod 61. Gears 62 are fixedly connected to both ends of the transmission rod 61. A rack plate 63 and a rack plate 64 are respectively meshed on the surfaces of the two gears 62. The top of the rack plate 63 is fixedly connected to the bottom of the right tabletop 2, and the top of the rack plate 64 is fixedly connected to the bottom of the left tabletop 2. Through the setting of the telescopic structure 6, the synchronous extension and retraction of the two tabletops 2 can be realized, ensuring the stability and consistency of the extension and retraction of the two tabletops 2. At the same time, the length of the tabletop 2 can be flexibly adjusted according to the number of participants.

[0029] It is worth noting that the technical features such as the one-way valve 53 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0030] Working Principle: When using the telescopic conference table, if the length of the conference table needs to be adjusted, first pull one side of the tabletop 2. This causes the tabletop 2 to move along with either rack plate 1 63 or rack plate 2 64. Since both rack plate 1 63 and rack plate 2 64 are engaged with gear 2 62, the movement of rack plate 1 63 or rack plate 2 64 will cause gear 2 62 to rotate, which in turn drives rack plate 1 63 or rack plate 2 64 on the other side to move. This causes both sides of the tabletop 2 to move synchronously in opposite directions, thus achieving the extension and retraction of the tabletop 2's length. During the movement of the tabletop 2, gear 2 62 drives the transmission rod 61 to rotate, which in turn drives gear 3 65 in the middle of the transmission rod 61 to rotate synchronously. This causes gear 3 65 to drive gear 1 526 to rotate, which in turn drives the swing arm 525 to move. The periodic oscillation causes the swing rod 525 to drive the piston rod 523 to move up and down via the rotating block 524. This causes the piston rod 523 to drive the piston plate 521 to reciprocate within the oil tank 55, thereby forcing the lubricating oil in the oil tank 55 into the oil pipe 54 through the one-way valve 53. Subsequently, the lubricating oil drips from one end of the oil pipe 54 onto the surface of the gear 62. The gear 62 then meshes with the rack plate 63 and the rack plate 64, thus achieving automatic lubrication while pulling the tabletop 2. When the tabletop 2 is pulled to the appropriate position, the folding table 3 is unfolded to a horizontal position via the hidden hinge. Then, the fixing bracket 42 is pulled outward, causing the fixing bracket 42 to slide in the groove 43 inside the fixing block 41, thus supporting the folding tabletop 2 and completing the fixing of the folding tabletop 3.
