[0039] Please see Figures 1 to 6 An adjustable desktop structure includes a table frame 1, a front tabletop 2, and a rear tabletop 3. When using the desktop structure, the user is generally positioned in front of it, while the opposite side of the desktop structure is considered the rear. Therefore, the front end of the table frame 1, front tabletop 2, and rear tabletop 3 refers to the end closer to the user, and the rear end refers to the end further away from the user. The rear tabletop 3 is slidably mounted on the table frame 1, meaning it can move back and forth relative to the table frame 1; moving forward brings it closer to the user, and moving backward moves it further away. The front tabletop 2 is slidably mounted on the front end of the table frame 1, and its rear end is hinged to the front end of the rear tabletop 3. In normal use, the front tabletop 2 and rear tabletop 3 are connected front to back and are horizontally aligned to form a single tabletop. Specifically, hinge structures are installed on the lower surfaces of the front tabletop 2 and rear tabletop 3. Figure 6 As shown (unspecified), one side of the hinge structure is connected to the lower end face of the front table panel 2, and the other side is connected to the lower end face of the rear table panel 3. The front table panel 2 and the rear table panel 3 are connected, therefore the front table panel 2 and the rear table panel 3 slide synchronously back and forth. The back-and-forth movement of the rear table panel 3 can drive the front table panel 2 to move back and forth, or vice versa. The force driving the back-and-forth movement of the front table panel 2 and the rear table panel 3 can be a force applied by the user or a force applied by a power mechanism. The horizontal height of the front end of the table frame 1 is lower than the upper end face of the table frame 1, therefore the front table panel 2 will tilt downwards at a certain angle when moving forward. Figure 1 and Figure 2 The first state of the height-adjustable desk shown is the state where the front tabletop 2 and the rear tabletop 3 are positioned rearwards during normal use. Figure 3 and Figure 4 The second state of the height-adjustable table shown is the state after the front tabletop 2 and the rear tabletop 3 have moved forward, through... Figure 3 It can be seen that at this time, the front table 2 not only moves forward, but also tilts downward at a certain angle. The downward tilt angle of the front table 2 is between 5° and 15°, which ensures that the items on the front table 2 do not slip off while ensuring that the front table 2 is tilted downward, thus preventing items from being placed on the front table 2.

[0040] The present technical scheme is characterized in that the front table plate 2 and the rear table plate 3 are hingedly connected together, and the horizontal height of the front end of the table frame 1 is lower than the upper end surface of the table frame 1, so that when the front table plate 2 and the rear table plate 3 move forward, the front table plate 2 can be inclined downward at the same time. Therefore, the user can use the table top structure more conveniently, the front table plate 2 is slightly inclined downward, and the user can use it more comfortably and conveniently touch the area of the rear table plate 3. In addition, the overall structure of the table top structure is more simple, and the inclination of the front table plate 2 can be realized only by driving the front table plate 2 and the rear table plate 3 to move forward, thereby eliminating the need to additionally set a structure for driving the front table plate 2 to incline, greatly reducing the manufacturing cost and manufacturing difficulty. Even if the front table plate 2 is inclined downward, the front table plate 2 always forms a whole table plate together with the rear table plate 3, and the user can use it more conveniently.

[0041] Please refer to Figure 7 and Figure 8 , the table frame 1 comprises a vertical rod 11, and the length direction of the vertical rod 11 is the direction in which the front table plate 2 and the rear table plate 3 move forward and backward. The horizontal height of the front end of the vertical rod 11 is lower than the upper end surface of the vertical rod 11, the rear table plate 3 is slidably installed on the vertical rod 11, and the front table plate 2 is slidably installed on the rear end of the vertical rod 11. The table frame 1 further comprises a horizontal rod 12, both ends of the horizontal rod 12 are provided with the vertical rod 11, so that two vertical rods 11 are provided, and the two vertical rods 11 are respectively located on both sides of the lower end of the front table plate 2 and the rear table plate 3. The rear table plate 3 is slidably installed on the two vertical rods 11 at the same time, and the front table plate 2 is slidably installed on the front end of the two vertical rods 11 at the same time. The horizontal rod 12 and the vertical rod 11 are perpendicular to each other, and the two vertical rods 11 are parallel to each other. The table frame 1 has a simple structure, and the shape of the vertical rod 11 can realize the inclination of the front table plate 2 when the front table plate 2 moves forward.

[0042] Please refer to Figure 9 , the vertical rod 11 comprises a horizontal section 111 and an inclined section 112, the rear end of the inclined section 112 is connected with the front end of the horizontal section 111, and the inclined section 112 is inclined from top to bottom from rear to front, so that the horizontal height of the front end of the vertical rod 11 is lower than the upper end surface of the vertical rod 11. Please refer to Figure 7 , a sliding piece 13 is installed on the front end of the inclined section 112, and the sliding piece 13 can rotate in the forward and backward direction relative to the inclined section 112. Please refer to Figure 6 , Figure 7 and Figure 10 , the lower end surface of the front table plate 2 is installed with a sliding sleeve 4, the sliding sleeve 4 is provided with a sliding groove 41, the length direction of the sliding groove 41 is consistent with the forward and backward movement direction of the front table plate 2, and the sliding piece 13 is slidably embedded in the sliding groove 41. The vertical rod 11 is composed of the horizontal section 111 and the inclined section 112, which has a simple structure and is convenient for production and manufacturing. The setting of the sliding piece 13 and the sliding sleeve 4 can improve the smoothness of the forward and backward movement of the front table plate 2, avoid the deviation of the front table plate 2 during the forward and backward movement, and improve the structural stability,

[0043] Please refer to Figure 10 The sliding sleeve 4 is hollow inside and has a sliding groove 41 formed in the lower end face. The height of the sliding sleeve 4 gradually decreases from front to back. Please refer to Figure 12 The sliding member 13 comprises a main body 131 and a sliding block 132. The main body 131 is rotatably installed at the front end of the inclined section 112, and the sliding block 132 is detachably installed on the main body 131 and located inside the sliding sleeve 4. During assembly, the main body 131 is first installed at the front end of the inclined section 112 of the vertical rod 11, then the sliding block 132 is placed inside the sliding sleeve 4, then the main body 131 is inserted into the sliding sleeve 4 from outside the sliding sleeve 4 through the sliding groove 41, and then the sliding sleeve 4 and the main body 131 are connected together; finally, the sliding sleeve 4 is installed at the lower end face of the table board. The sliding member 13 has a simple structure and can ensure smooth movement of the front table board 2, and the overall structure is more convenient to assemble. In addition, the structure of the sliding sleeve 4 can ensure that the sliding block 132 is always embedded in the sliding sleeve 4 under the premise of ensuring the forward movement of the front table board 2, thereby ensuring the stability of the structure.

[0044] Please refer to Figure 8 and Figure 11 The inclined sleeve 14 is installed on the inclined section 112, and the sliding member 13 is installed at the front end of the inclined sleeve 14. The horizontal section 111 and the inclined section 112 are of an integrated structure and constitute the vertical rod 11; and in order to ensure the structural strength, the vertical rod 11 is generally made of metal material. If the sliding member 13 is directly installed at the front end of the inclined section 112, the structure of the vertical rod 11 will be more complex and the manufacturing cost will be higher. In the embodiment, the inclined sleeve 14 is installed on the inclined section 112, and the sliding member 13 is installed at the front end of the inclined sleeve 14, which is more convenient for subsequent maintenance and replacement of the structure at this position, without the need to maintain and replace the entire vertical rod 11, thereby reducing the subsequent maintenance cost.

[0045] Please refer to Figure 11 The front end of the inclined sleeve 14 is provided with a mounting portion 15, which is hollow inside and has first shaft holes 16 formed at both sides. Please refer to Figure 12 The lower end of the sliding member 13 is provided with a second shaft hole 133, and the lower end of the sliding member 13 is located in the hollow area of the mounting portion 15, at this time the two first shaft holes 16 and the second shaft hole 133 are in communication; a pin shaft (not shown in the figure) passes through the first shaft hole 16 and the second shaft hole 133 to rotatably install the sliding member 13 on the mounting portion 15. In this way, the sliding member 13 can be conveniently assembled and disassembled, and the structure is simple and convenient to assemble.

[0046] Please refer to Figure 6The adjustable table top structure further comprises a driving mechanism 5, which can be installed on the table frame 1 or other positions of the table, and can ensure that the driving mechanism 5 drives the front table plate 2 and the rear table plate 3 to move forward and backward synchronously. For example, the output end of the driving mechanism 5 is connected with the rear table plate 3, and drives the rear table plate 3 to move forward and backward, thereby synchronously driving the front table plate 2 to move forward and backward. Of course, the output end of the driving mechanism 5 can also be connected with the front table plate 2, and drives the front table plate 2 to move forward and backward, thereby synchronously driving the rear table plate 3 to move forward and backward. By arranging the driving mechanism 5, the forward and backward movement of the front table plate 2 and the rear table plate 3 can be automatically controlled; and a single driving mechanism 5 can realize the functions of translation of the front table plate 2 and the rear table plate 3 and tilting of the front table plate 2.

[0047] Please refer to Figure 13 The driving mechanism 5 comprises a motor 51, a screw rod 52 and a nut movable seat 53. The motor 51 is installed on the vertical rod 11, the screw rod 52 is in transmission connection with the output end of the motor 51 and has the same length direction as the direction of the forward and backward movement of the rear table plate 3, and the nut movable seat 53 is in threaded transmission connection with the screw rod 52 and is connected with the lower end surface of the rear table plate 3. The motor 51 is a power output mechanism, and the user can control the start and stop of the motor 51 through a control panel or the like. When the motor 51 works, the output end thereof drives the screw rod 52 to rotate, and the screw rod 52 drives the nut movable seat 53 to slide along the length direction of the screw rod 52 when rotating, and the nut movable seat 53 drives the rear table plate 3 to move forward and backward synchronously when sliding. The driving mechanism 5 has a simple structure and can conveniently realize the power control of the forward and backward movement of the rear table plate 3.

[0048] Specifically, the screw rod 52 is located in the vertical rod 11, has the same length direction as the vertical rod 11, and can rotate around the axis of the vertical rod 11. The upper end surface of the vertical rod 11 is provided with a long slot 113, and the long slot 113 has the same length direction as the screw rod 52. The nut movable seat 53 is provided with a connecting block 54, the connecting block 54 passes through the long slot 113 and is connected with the rear table plate 3, and the connecting block 54 can freely slide in the long slot 113. By arranging the screw rod 52 in the vertical rod 11, the screw rod 52 and the nut movable seat 53 can be hidden, so as to avoid the influence of external factors on the rotation of the screw rod 52 and the movement of the nut movable seat 53, and also avoid the harm to the user caused by the rotation of the screw rod 52. By arranging the long slot 113 and the connecting block 54, the connection between the nut connecting block 54 and the rear table plate 3 can be realized, and the overall structure is simpler. On the other hand, by arranging the long slot 113, the range of the forward and backward movement of the connecting block 54 can be limited, so as to ensure that the forward and backward movement of the front table plate 2 and the rear table plate 3 is within a controllable range.

[0049] Please refer to Figure 6 and Figure 7The lower end surface of the rear table plate 3 is detachably provided with a connecting piece 6, and the connecting block 54 is connected with the connecting piece 6 through the long slot 113. The middle position of the connecting piece 6 is concave, and the lower concave position is provided with a hole position. The connecting block 54 is provided with a corresponding threaded hole. A screw is screwed into the threaded hole of the connecting block 54 through the hole position of the lower concave position of the connecting piece 6, so as to connect the connecting block 54 with the connecting piece 6. The two sides of the connecting piece 6 also have holes, and the connecting piece 6 can be installed on the lower end surface of the rear table plate 3 by screwing. Through the setting of the connecting piece 6, the rear table plate 3 and the connecting block 54 can be connected.

[0050] Please refer to Figure 13 and Figure 14 The driving mechanism 5 further comprises a transmission rod 55 and a rotating conversion head 56 located in the vertical rod 11. The rotating conversion head 56 comprises a first bevel gear 561 and a second bevel gear 562 which are engaged with each other. The motor 51 is located at the rear end position of the vertical rod 11, and the motor 51 is installed outside the vertical rod 11 through an L-shaped connecting plate (not shown in the figure). One end of the transmission rod 55 is in transmission connection with the output end of the motor 51. The vertical rod 11 is provided with a hole position on the side close to the motor 51. The other end of the transmission rod 55 extends into the vertical rod 11 through the hole position and is inserted into the rotating conversion head 56. The first bevel gear 561 in the rotating conversion head 56 is sleeved on the other end of the transmission rod 55. One end of the screw rod 52 is inserted into the rotating conversion head 56, and the second bevel gear 562 in the rotating conversion head 56 is sleeved on one end of the screw rod 52. The screw rod 52 is perpendicular to the transmission rod 55. When the motor 51 operates, the output end drives the transmission rod 55 to rotate, and the first bevel gear 561 rotates synchronously. The first bevel gear 561 and the second bevel gear 562 are engaged, so the second bevel gear 562 rotates with the first bevel gear 561, and the second bevel gear 562 drives the screw rod 52 to rotate synchronously. The rotation of the screw rod 52 can drive the nut movable seat 53 to move, and then drive the rear table plate 3 to move forward and backward. The motor 51 is arranged outside the vertical rod 11, which is convenient for connecting wires and control lines and convenient for maintenance. Through the setting of the transmission rod 55 and the rotating conversion head 56, the rotational motion transmission between the transmission rod 55 and the screw rod 52 can be realized, so that the power of the motor 51 outside the vertical rod 11 is stably transmitted to the screw rod 52 inside the vertical rod 11.

[0051] In this embodiment, two groups of driving mechanisms 5 are provided, and the two groups of driving mechanisms 5 are respectively arranged on the two vertical rods 11. The two groups of driving mechanisms 5 work synchronously to realize the smooth movement of the front table plate 2 and the rear table plate 3. Of course, in other embodiments, only one group of driving mechanisms 5 can be provided to realize electric control.
