[0002] At present, the commonly used desks mainly include a desk box, a support column and a bottom plate from top to bottom, which can meet the daily use needs of most people. However, after sitting for a long time, users will inevitably become tired. Based on this problem, in order to improve the comfort when using the desk, some manufacturers will set a matching small pedal on the support column at the bottom of the desk as a place to put the feet. The setting of the small pedal can improve the comfort of the user's legs.

[0003] With regard to the above-mentioned related technologies, the pedal position is fixed on the support column. In actual use, when the user's legs are too long or too short, the fixed pedal is difficult to increase the user's comfort, and may even have the opposite effect; and when the distance between the seat and the desk is too large or too small, the pedal is also difficult to increase the user's comfort.

The two lifting rods 52 are arranged in the horizontal direction at intervals from each other. The two sides of the two lifting rods 52 that are away from each other are connected to the inner wall of the installation groove 21. The connecting block 51 is located between the two lifting rods 52. The two sides of the connecting block 51 in the horizontal direction are respectively connected to the corresponding side walls of the lifting rods 52 in the vertical direction. Therefore, the connecting block 51 can move in the vertical direction between the two lifting rods 52.

[0046] Reference Figure 3 and Figure 4 A connecting rod driving assembly 53 is provided between the connecting block 51 and the foot pedal 4.

[0047] Reference 4 and Figure 5 The connecting rod driving assembly 53 includes a rotational clearance hole 516, and a rotational clearance hole 516 is opened in the horizontal direction on the connecting block 51. The axial direction of the rotational clearance hole 516 is perpendicular to the opening direction of the first sliding groove 511, and the rotational clearance hole 516 is connected to the first sliding groove 511 and the second sliding groove 513.

Therefore, during the rotation of the driving shaft 531, the first driving rod 532 can drive the first lifting support block 512 to slide in the first sliding groove 511, and the second driving rod 533 can drive the second lifting support block 514 to slide in the second sliding groove 513, so as to realize the release and opening of the lock between the connecting block 51 and the two lifting rods 52.

[0050] Reference 4 and Figure 5 A first driving yielding groove 517 is formed on the inner wall of the rotation yielding hole 516 on the side facing the first sliding groove 511, and the first driving rod 532 passes through the first driving yielding groove 517, and the inner wall of the first driving yielding groove 517 is slidably connected with or spaced apart from the first driving rod 532; a second driving yielding groove 518 is formed on the inner wall of the rotation yielding hole 516 on the side facing the second sliding groove 513, and the second driving rod 533 passes through the second driving yielding groove 518, and the inner wall of the second driving yielding groove 518 is slidably connected with or spaced apart from the second driving rod 533. By providing the first driving yielding groove 517 and the second driving yielding groove 518, when the first driving rod 532 and the second driving rod 533 are driven by the driving shaft 531, space can be reserved for the rotation of the first driving rod 532 and the second driving rod 533.

[0051] Reference Figure 4 , a plurality of return springs 515 are arranged in the first sliding groove 511 and the second sliding groove 513, and the axial direction of the return spring 515 is arranged along the opposite direction of the two lifting rods 52, and the two ends of the return spring 515 in the first sliding groove 511 are respectively connected to the first lifting support block 512 and the inner wall of the first sliding groove 511, and the two ends of the return spring 515 in the second sliding groove 513 are respectively connected to the second lifting support block 514 and the inner wall of the second sliding groove 513. Therefore, under the action of the return spring 515, during the process of the connection block 51 being raised or lowered, the first lifting support block 512 and the second lifting support block 514 can be automatically driven to contact the corresponding side wall of the lifting rod 52, so that the first lifting support block 512 and the second lifting support block 514 can be inserted into the corresponding lifting positioning groove 521 in time, thereby fixing the connection block 51 in time.

[0052] Reference Figure 4The upper side of the lifting and positioning groove 521 in the vertical direction is an inclined guide surface 522, which is inclined from top to bottom in the direction away from the connecting block 51, and the lower side of the lifting and positioning groove 521 in the vertical direction is a horizontally arranged support surface 523; the side of the support surface 523 away from the connecting block 51 is connected to the lower side of the guide surface 522, and the side of the support surface 523 close to the connecting block 51 is connected to the upper side of the guide surface 522 of another lifting and positioning groove 521 on the lower side in the vertical direction. In addition, the first lifting support block 512 and the second lifting support block 514 cooperate with the guide surface 522 on the side facing the corresponding lifting rod 52. Therefore, the setting of the guide surface 522, on the one hand, facilitates the insertion of the first lifting support block 512 and the second lifting support block 514, and on the other hand, by applying force to the connecting block 51 in the vertical direction, the guide surface 522 can automatically push the first lifting support block 512 into the corresponding first sliding groove 511 and the second lifting support block 514 into the corresponding second sliding groove 513, thereby realizing the lifting and lowering of the connecting block 51 in the vertical direction.

[0053] Reference Figure 2 and 3 The lower side of the connection block 51 is provided with an elastic reset member 54, which is a gas spring, and the lower end of the elastic reset member 54 is connected to the inner wall of the mounting groove 21, and the upper end of the elastic reset member 54 is connected to the connection block 51. Therefore, when the locking between the connection block 51 and the two lifting rods 52 is released, the elastic reset member 54 will automatically lift the connection block 51, thereby facilitating the lifting of the connection block 51.

[0054] Reference Figure 2 and Figure 6 , both ends of the driving shaft 531 are coaxially connected with a linkage shaft 534, the supporting column 2 is provided with a sliding long slot 22 on both opposite sides in the horizontal direction, the sliding long slot 22 is connected with the mounting slot 21 and the length direction of the sliding long slot 22 is arranged in the vertical direction, the linkage shaft 534 is plugged and matched with the corresponding sliding long slot 22 and the linkage shaft 534 is slidably connected with the inner wall of the corresponding sliding long slot 22 in the vertical direction; the end of the linkage shaft 534 away from the connecting block 51 is connected with the foot pedal 4.

Therefore, the support ring 6 can support the foot pedal 4 in the vertical direction. The foot pedal 4 is sleeved on the outer side of the support ring 6, and the inner wall of the foot pedal 4 and the outer wall of the support ring 6 are spaced apart from each other.

The first hole 621 is provided on the pedal 4 along the radial direction of the support ring 6, and the second hole 622 is provided on the support ring 6 along the radial direction of the support ring 6. When the pedal 4 is horizontal, the first hole 621 and the second hole 622 are communicated with each other. At this time, a locking bolt 623 is coaxially inserted into the first hole 621 and the second hole 622. Thus, the setting of the reinforcement assembly 62 fixes the support ring 6 and the pedal 4. At this time, the pedal 4 cannot rotate, and the position of the pedal 4 is fixed.

[0057] The implementation principle of the embodiment of the present application is as follows: when the position of the foot pedal 4 needs to be adjusted, first, the locking bolt 623 is pulled out. Then, the foot pedal 4 is stepped on to release the lock between the connecting block 51 and the lifting rod 52. After that, a force is applied vertically downward to the foot pedal 4, and the foot pedal 4 moves downward; if no force is applied to the foot pedal 4, the foot pedal 4 automatically moves upward under the action of the elastic reset member 54. Finally, when the foot pedal 4 moves to a suitable position, the foot pedal 4 is loosened and the locking bolt 623 is inserted. At this time, the position of the foot pedal 4 is fixed and is in a position that can make the user comfortable.

[0058] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks.
