[0035] The following describes a study table leg 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0036] like Figures 1-6 As shown, the study table leg 1 according to an embodiment of the present invention includes a fixed leg 100 , a lifting leg 200 , a matching piece 130 and a driving device 300 .

[0037] The fixed leg 100 is used to be placed on the ground, the lifting leg 200 and the fixed leg 100 are sleeved and connected, and the lifting leg 200 can be raised and lowered relative to the fixed leg 100, the mating piece 130 is connected to the fixed leg 100, and the mating piece 130 is constructed with a threaded mating hole 132, the driving device 300 is connected to the lifting leg 200 and includes a driving assembly (not shown in the figure) and a transmission screw 320, the driving assembly is in transmission connection with the transmission screw 320, the transmission screw 320 is passed through the lifting leg 200 and cooperates with the threaded mating hole 132.

[0038] Among them, the lifting leg 200 and the fixed leg 100 are connected in a sleeve manner, which means that the lifting leg 200 can be sleeved on the outside of the fixed leg 100, or the fixed leg 100 can be sleeved on the outside of the lifting leg 200, so that the lifting leg 200 can be raised and lowered relative to the fixed leg 100. By adjusting the position of the lifting leg 200 relative to the fixed leg 100, the height of the study table leg 1 can be changed to meet the different needs of users.

[0039] In addition, the driving assembly may include a driving motor, gears and other structures.

[0040] Among them, the driving component can be connected to the upper end of the lifting leg 200 in the height direction, and the transmission screw 320 passes through the lifting leg 200 and cooperates with the threaded matching hole 132 on the matching part 130. In this way, not only can the lifting leg 200 be used to protect the transmission screw 320, but also after the transmission screw 320 cooperates with the threaded matching hole 132, the transmission screw 320 can be prevented from interfering with the fixed leg 100. For example, the transmission screw 320 can be prevented from interfering with the fixed leg tube 120 described below.

[0041] According to the study table leg 1 of the present invention, the mating member 130 is connected to the fixed leg 100, and a threaded mating hole 132 is provided on the mating member 130. The transmission screw 320 engages with the threaded mating hole 132. Thus, when the drive assembly drives the transmission screw 320, the transmission screw 320 can move in the vertical direction by engaging with the threaded mating hole 132, thereby causing the lifting leg 200 to move in the vertical direction relative to the fixed leg 100, thereby achieving height adjustment of the study table leg 1. Furthermore, compared to the related art method of providing an aluminum tube and a threaded mating screw, in this embodiment, the mating member 130 is directly fixed to the fixed leg 100 and the threaded mating hole 132 is provided on the mating member 130. This simplifies the transmission connection structure between the drive device 300 and the fixed leg 100, thereby simplifying the structure of the study table leg 300, facilitating assembly of the drive device 300 and the fixed leg 100, and improving the assembly efficiency of the study table leg 1.

[0042] In this way, the study table leg 1 according to the embodiment of the present invention can simplify the relative lifting structure of the lifting leg 200 and the fixed leg 100, and has the advantages of simple structure and easy assembly.

[0043] In some specific embodiments of the present invention, Figure 2 and Figure 3 As shown, the lifting leg 200 is sleeved on the fixed leg 100 , and the fitting 130 is adjacent to the upper end of the fixed leg 100 .

[0044] With this arrangement, the height of the fitting 130 can be higher, so that the distance between the fitting 130 and the transmission screw 320 can be smaller, and the length of the transmission screw 320 does not need to be set too long, so that the transmission screw 320 can be connected and matched with the threaded matching hole 132, the connection is more reliable, and the lifting and lowering of the study table leg 1 can be made more stable. Moreover, since the lifting leg 200 is arranged outside the fixed leg 100, that is, the lifting leg 200 does not need to be extended into the fixed leg 100, no matter whether the fitting 130 is arranged at the upper end or the lower end of the fixed leg 100, the fitting 130 will not block the lifting and lowering of the lifting leg 200, so that the study table leg 1 can be lifted and lowered normally.

[0045] In addition, in some embodiments, the fixed leg 100 is mounted on the outside of the lifting leg 200. At this time, the matching piece 130 can be arranged inside the fixed leg 100 and adjacent to the lower end of the fixed leg 100. In this way, the height of the matching piece 130 can be lower. When the lifting leg 200 descends relative to the fixed leg 100, even if the lifting leg 200 descends to a lower position, the height of the matching piece 130 is also lower, that is, the height of the matching piece 130 can always be lower than the height of the lowest end of the lifting leg 200, thereby avoiding positional interference between the lifting leg 200 and the matching piece 130 when descending, so that the study table leg 1 can be raised and lowered normally.

[0046] In some specific embodiments of the present invention, Figure 2 and Figure 6 As shown, the fixed leg 100 may include a base 110 and a fixed leg tube 120 .

[0047] The base 110 is suitable for being placed on the ground. The fixed leg tube 120 is connected to the base 110 . The fixed leg tube 120 is suitable for extending in an up-down direction. The fitting 130 is connected to the fixed leg tube 120 .

[0048] The fixed leg tube 120 and the base 110 can be separately processed and formed and then connected together, which is conducive to simplifying the processing steps of the fixed leg 100.

[0049] In addition, by setting the fixed leg tube 120 and the matching part 130 separately, this not only simplifies the processing of the fixed leg tube 120 and the matching part 130, but also allows the relative position of the matching part 130 and the fixed leg tube 120 to be adjusted according to the specific structure, and then the matching part 130 and the fixed leg tube 120 are connected and fixed, so that the distance between the matching part 130 and the driving device 300 can be changed to facilitate the matching of the transmission screw 320 and the threaded matching hole 132 of the matching part 130.

[0050] In some specific embodiments of the present invention, Figure 5 As shown, the fitting 130 includes a main body portion 131 and an anti-friction portion 134 .

[0051] The main body 131 is constructed with a threaded fitting hole 132. The main body 131 is arranged at the upper end of the fixed leg tube 120. The anti-friction part 134 is connected to one side of the thickness direction of the main body 131. The anti-friction part 134 is sleeved on the fixed leg tube 120 and clamped between the fixed leg tube 120 and the lifting leg 200.

[0052] For example, the lifting leg 200 is sleeved on the outside of the fixed leg 100 , the fitting 130 can be connected to the upper end of the fixed leg tube 120 , and the anti-friction portion 134 is sandwiched between the fixed leg tube 120 and the lifting leg 200 .

[0053] Thus, when the lifting leg 200 is raised or lowered relative to the fixed leg tube 120, the anti-friction portion 134 reduces the friction force during the lifting leg 200's movement by reducing the contact area between the fixed leg tube 120 and the lifting leg 200, making the lifting of the lifting leg 200 easier and more labor-saving. Furthermore, the anti-friction portion 134 fills the gap between the fixed leg 100 and the lifting leg 200, ensuring that the lifting leg 200 remains stable when raised or lowered relative to the fixed leg 100, thus preventing the study table leg 1 from shaking or tilting.

[0054] In addition, the main body 131 is disposed at the upper end of the fixed leg tube 120, allowing the drive screw 320 to be relatively close to the main body 131, facilitating the connection and mating of the drive screw 320 with the threaded mating hole 132, and facilitating assembly of the drive screw 320 with the mating member 130. Furthermore, the threaded mating hole 132 constructed in the main body 131 allows the drive screw 320 to be raised or lowered relative to the mating member 130 by mating with the threaded mating hole 132. Furthermore, the threaded mating hole 132 can limit the radial position of the drive screw 320 along the threaded mating hole 132, preventing positional interference between the drive screw 320 and the fixed leg tube 120.

[0055] In some specific embodiments of the present invention, Figure 2 and Figure 5 As shown, the main body 131 is further configured with at least one first connection hole 133 , and the upper end of the fixed leg tube 120 is provided with at least one second connection hole 121 , and the first connection hole 133 and the second connection hole 121 are threadedly connected by fasteners.

[0056] There may be a plurality of first connection holes 133 and a plurality of second connection holes 121 . The plurality of first connection holes 133 and the plurality of second connection holes 121 may be connected in a one-to-one correspondence via fasteners.

[0057] For example, two first connecting holes 133 can be set, and the two first connecting holes 133 can be distributed on both radial sides of the threaded fitting hole 132 and are spaced apart from the threaded fitting holes 132 respectively. At the same time, two second connecting holes 121 are constructed at the upper end of the fixed leg tube 120, and the two second connecting holes 121 are respectively connected to the two first connecting holes 133 in a one-to-one correspondence through fasteners. This can improve the connection strength between the fitting 130 and the fixed leg tube 120, and can prevent the fitting 130 from rotating relative to the fixed leg tube 120, so that the connection between the fitting 130 and the fixed leg tube 120 is more stable.

[0058] In addition, it should be noted that the fitting 130 and the fixed leg tube 120 can also be connected by providing a snap-fit ​​structure.

[0059] In some specific embodiments of the present invention, Figure 2 and Figure 4 As shown, the driving device 300 further includes a stopper 330 , which is connected to an end of the transmission screw 320 away from the driving assembly, and the stopper 330 stops at a side of the fitting 130 facing away from the driving assembly.

[0060] For example, the stopper 330 may be a limit screw, and the stopper 330 may be threadedly connected to an end of the transmission screw 320 away from the driving assembly.

[0061] By setting the stopper 330, when the lifting leg 200 rises to the maximum height relative to the fixed leg 100, the stopper 330 can stop against the matching piece 130, so that the stopper 330 can be used to limit the maximum height to which the lifting leg 200 rises, that is, the maximum height to which the transmission screw 320 rises can be limited, thereby preventing the transmission screw 320 from separating from the matching piece 130 when the lifting leg 200 rises relative to the fixed leg 100, so that the transmission screw 320 and the matching piece 130 can be more stably matched, and the lifting and lowering of the study table leg 1 can be more stable.

[0062] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the lifting leg 200 includes a lifting leg tube 210 and a connecting plate 220 .

[0063] The lifting leg tube 210 is sleeve-connected to the fixed leg 100 , the connecting plate 220 is arranged at the upper end of the lifting leg tube 210 , and the connecting plate 220 is provided with an avoidance hole 221 , the driving assembly is arranged on the side of the connecting plate 220 facing away from the lifting leg tube 210 and the screw rod is passed through the avoidance hole 221 .

[0064] In this way, the drive assembly can be fixed by the connecting plate 220 to prevent the drive assembly from moving in the height direction of the lifting leg 200. In addition, the avoidance hole 221 can avoid the transmission screw 320, preventing the transmission screw 320 from interfering with the connecting plate 220 and the lifting leg 200, so that the drive assembly can drive the transmission screw 320 to rotate, and the structural arrangement is more reasonable.

[0065] In some specific embodiments of the present invention, Figure 2 and Figure 4 As shown, the driving device 300 further includes a box body 310 , the driving assembly is relatively fixed to the box body 310 , and a limiting portion 311 is provided on one side of the box body 310 , which extends into the avoidance hole 221 and cooperates with the side wall of the avoidance hole 221 .

[0066] It should be noted that there are multiple ways to fix the drive assembly to the box 310, which are described below with examples:

[0067] 1. When the driving component is a motor, and one motor drives one study table leg 1 to move up and down, the motor can be set in the box 310, and no gear is required. The motor can be directly connected to the transmission screw 320;

[0068] Second, when the driving component is a motor, and one motor drives the two study table legs 1 to move up and down, the motor can be arranged outside the box 310, and a gear is provided inside the box 310, and the output shaft of the motor is connected to the gear in the box 310;

[0069] 3. When the driving component is a manual rocker, the manual rocker can be inserted into the box body 310 from the outside and connected to the gear transmission inside the box body 310, and then the transmission screw 320 can be rotated by rotating the manual rocker.

[0070] The avoidance hole 221 is configured as a non-circular hole, and the cross-sectional shape of the limiting portion 311 is configured as a non-circular shape adapted to the avoidance hole 221 to prevent the box body 310 from rotating relative to the connecting plate 220 .

[0071] For example, the avoidance hole 221 may be a square hole, an elliptical hole or other irregular non-circular hole, and the cross-sectional shape of the limiting portion 311 may be constructed as a square hole, an elliptical hole or other irregular non-circular hole that matches the avoidance hole 221 .

[0072] The housing 310 can be used to secure the drive assembly, facilitating installation and protecting the drive assembly. Furthermore, the stopper 311 cooperates with the avoidance hole 221 to prevent the housing 310 from rotating relative to the connecting plate 220, thereby ensuring a more stable and reliable relative position between the drive device 300 and the lifting leg 200.

[0073] In some specific embodiments of the present invention, Figure 2 As shown, the study table leg 1 also includes an anti-friction part 400, which is connected to the lifting leg 200 and is arranged at the lower end of the lifting leg 200. The anti-friction part 400 is clamped between the fixed leg 100 and the lifting leg 200 to prevent the lifting leg 200 from shaking relative to the fixed leg 100.

[0074] For example, the lifting leg 200 can be mounted on the outside of the fixed leg 100, in which case the anti-friction member 400 can be connected to the inner circumference of the lifting leg 200 and be arranged at the lower end of the lifting leg 200; or, the fixed leg 100 can be mounted on the outside of the lifting leg 200, in which case the anti-friction member 400 can be connected to the outer circumference of the lifting leg 200 and be arranged at the lower end of the lifting leg 200.

[0075] In this way, when the lifting leg 200 is raised or lowered relative to the fixed leg 100, the anti-friction part 400 can move together with the lifting leg 200. No matter to which height the lifting leg 200 rises within the adjustable range, the anti-friction part 400 can be maintained between the fixed leg 100 and the lifting leg 200, thereby ensuring that the anti-friction part 400 can always fill the gap between the lifting leg 200 and the fixed leg 100, so that the lifting leg 200 remains stable relative to the fixed leg 100, thereby preventing the study table leg 1 from shaking or tilting.

[0076] In addition, the anti-friction member 400 is clamped between the fixed leg 100 and the lifting leg 200, which can reduce the contact area between the fixed leg 100 and the lifting leg 200. Therefore, when the lifting leg 200 is raised or lowered relative to the fixed leg 100, the anti-friction member 400 can reduce the friction between the fixed leg 100 and the lifting leg 200, so that the lifting movement of the lifting leg 200 is easier and more labor-saving.

[0077] The following describes a study table according to an embodiment of the present invention with reference to the accompanying drawings.

[0078] The study table includes a table top and a plurality of study table legs 1 according to the above embodiment of the present invention, and the lifting legs 200 of the plurality of study table legs 1 are connected to the lower side of the table top.

[0079] Among them, multiple study table legs 1 can be arranged at intervals along the length direction or width direction of the table top, so that multiple study table legs 1 can jointly support the table top, which is beneficial to improving the support stability of the table top.

[0080] The study table according to the embodiment of the present invention can simplify the relative lifting structure of the lifting leg 200 and the fixed leg 100 by utilizing the study table leg 1 according to the above embodiment of the present invention, and has the advantages of simple structure and easy assembly.

[0081] The study table legs 1 and other structures and operations of the study table according to the embodiment of the present invention are well known to ordinary technicians in this field and will not be described in detail here.
