The stable supporting mechanism further comprises a limiting pile 2, N (4 in the embodiment) groups of limiting assemblies 3 and N (4 in the embodiment) groups of supporting frames 4, wherein the limiting pile 2 can be used for being connected with an object to be supported (such as a table foot of a table), the limiting pile 2 is in axial transmission connection with the base 11, namely, the limiting pile 2 can move axially relative to the base 11, and the central axis of the limiting pile 2 coincides with the central axis of the base 11, so that the center of gravity offset between the limiting pile 2 and the base 11 is avoided, the stability of the stable supporting mechanism in use is ensured, and the supporting stability of the stable supporting mechanism on the object is ensured. Taking a single-leg desk as an example, a desk leg is fixed at the center of the bottom of the desktop, the bottom of the desk leg is fixedly connected with the limiting pile 2, namely, the limiting pile 2 is fixedly connected with the stabilizing and supporting mechanism, and the automatic adjustment under different ground environments is met by utilizing each support frame 4 connected with the pile foundation 1 and the movable connection relationship of the support frame 4, so that the stable support of the desk is ensured, and the stability, balance and no shaking of the desk are ensured.

When the table is moved, the limiting pile 2 drives the limiting component 3 to be moved along with the lifting of the table, and the pile foundation 1 and the N groups of support frames 4 also move along with the lifting of the table under the locking of the hook 30; when the desk falls down, spacing stake 2 is pushed down, utilizes the transmission effect between spacing subassembly 3 and lateral wall 101 and the strut 4, and each strut 4 is balanced in coordination, supports spacing to spacing stake 2, and then guarantees the stability of the desk of being connected with spacing stake 2.

The bracket 4 is rotatably connected with the support 12, and the end of the bracket 4 is in transmission connection with the limiting assembly 3, which can also be understood as that the end of the bracket 4 is in transmission connection with the side wall 101 of the base 11 through the transmission action of the limiting assembly 3. Namely, the N groups of brackets 4 are respectively rotatably connected with the N supports 12 in a one-to-one correspondence manner, and the end of each group of brackets 4 is respectively in transmission connection with the side wall 101 on the corresponding side of the base 11 through one group of limiting assemblies 3. According to the actual stress situation, by the rotatable connection with the support 12 and the transmission connection with the side wall 101, each group of brackets 4 can automatically adjust the stable position thereof, and then the N groups of brackets 4 are mutually matched to ensure the stability of the supported table.

In this embodiment, the spacing assembly 3 comprises a connecting piece 31, a roller 32, a roller pin 33 and a spring 34.

Fig. 5 shows a schematic structural diagram of the connecting piece 31, and as shown in fig. 4 and 5, a rectangular hole 311 is formed in the middle of the connecting piece 31, pin holes 312 are formed at two ends of the rectangular hole 311, a mounting groove 313 is formed above the rectangular hole 311, the roller 32 is located in the rectangular hole 311, the roller 33 passes through the roller 32, two ends of the roller 33 are located in the pin holes 312, and the spring 34 is located in the mounting groove 313. The top end of the spring 34 is in contact with the top end of the mounting groove 313, and the bottom end of the spring 34 is in contact with the roller 32. Wherein, the length of the rectangular hole 311 is greater than the length of the roller 32, and the height of the rectangular hole 311 is greater than the outer diameter of the roller 32, so that the roller 32 can smoothly move up and down in the rectangular hole; the height of the mounting groove 313 is smaller than the length of the spring 34, so that the bottom end of the spring 34 is always in contact with the roller 32, and the elastic force of the spring can act on the roller 32. The inner diameter of the roller 32 is larger than the diameter of the roller pin 33, and the difference between the height of the rectangular hole 311 and the outer diameter of the roller 32 is larger than the difference between the inner diameter of the roller 32 and the diameter of the roller pin 33 to ensure that the roller 32 can elastically move up and down. Illustratively, the inner diameter of the roller 32 is greater than 1.5 times of the diameter of the roller pin 33, and the spring 34, in combination with the cooperation of the gap between the roller 32 and the roller pin 33, can ensure that the connecting piece 31 can smoothly bring the roller 32 away from or close to the space between the bracket 4 and the side wall 101, and at the same time, can ensure that the roller 32 has a certain movable gap, which facilitates the adaptive coordination between different brackets 4, and further ensures the support stability of the stable support mechanism.

Specifically, the end of the supporting frame 4 is in transmission connection with the side wall 101 of the base 11 through the roller 32 and the spring 34. When the table is put down, the tail end of the supporting frame 4 lands, the table top enables the limiting pile 2 to drive the connecting sheet 31 to be pressed downwards, and the spring 34 is compressed; under the action of the elastic restoring force of the spring 34, the roller 32 is pressed down between the bracket 4 and the side wall 101 of the base 11 and is continuously pressed down, so that the end of the bracket 4 moves downwards relative to the base 11, that is, the bracket 4 rotates around the support 12 until the roller 32 is clamped by the end of the bracket 4 and the side wall 101 of the base 11, and the position of the bracket 4 is locked. In the process that the table is put down, under the action of gravity of the table, the N groups of brackets 4 and the pile foundation 1 are in cooperative transmission and are locked according to the process, so that balance is achieved, and stable and balanced support of the table is realized. On the contrary, when moving the desk, the desk is lifted, drive connection piece 3 through spacing stake 2 and upwards move, reduce the pressure to spring 34 gradually, until the bottom of rectangular hole 311 and roller 32 contact, connection piece 3 continues to move up under the effect of conveying the lifting force to spacing stake 2 through the desk, drive roller 32 and move up, take roller 32 from between bracket 4 and pile foundation 1, until couple 30 and base 11 contact, drive pile foundation 1 and the N group of bracket 4 of being connected with pile foundation 1 and move along with the removal of spacing stake 2 simultaneously, move along with moving of desk promptly. In the process, after the roller 32 is taken away from the position between the bracket 4 and the pile foundation 1 by the connecting piece 3, the bracket 4 loses the clamping force, and rotates relative to the support 12 under the action of gravity along with the process that the pile foundation 1 is lifted until the top surface of the end part of the bracket 4 is contacted with the support 12 and is stable. In order to ensure that the rollers 32 cannot be separated from the rectangular holes 311 in the lifting process of the connecting sheet 3, the bottom surfaces of the rectangular holes 311 are of arc-shaped surface structures with the diameters equal to the outer diameters of the rollers 32. Meanwhile, when the table is moved, the connecting sheet 31 takes the roller sleeve 32 away from the position between the support frame 4 and the pile foundation 1, so that the problem that the support frame 4 is locked in advance when the table is put down and cannot be adjusted adaptively according to the ground flatness can be effectively avoided.

It should be noted that, in the state that the hook 30 is in contact with the base 11, the distance between the bottom end of the position-limiting pile 2 and the bottom of the base 11 is greater than or equal to the difference between the height of the rectangular hole 311 and the outer diameter of the roller 32, so as to avoid the situation that the bottom end of the position-limiting pile 2 is in contact with the base 11 before the support 4 is clamped and reaches a stable state, which causes the position-limiting pile 2 to press down the base 11 under the gravity of the table, and makes it difficult for the support 4 to reach a balance state. During actual production and test, after the stable supporting mechanism supports stably, a gap not smaller than 1mm is reserved between the bottom end of the limiting pile 2 and the bottom of the inner cavity of the base 11.

Meanwhile, the outer diameter of the roller 32 needs to be larger than the minimum distance between the end of the support frame 4 and the side wall 101 of the base 11, so that the roller 32 can be clamped between the support frame 4 and the side wall 101 to limit the support frame 4 and ensure the support stability of the support frame 4.

In order to ensure the structural stability of the pile foundation 1, rib plates 14 are arranged between the adjacent supports 12, and each rib plate 14 fixes and supports the two adjacent supports 12.

In order to ensure the connection stability between the support 12 and the support 4, a U-shaped groove 121 is arranged at the bottom of the support 12, and the end part of the support 4 is positioned in the U-shaped groove and is rotatably connected with two walls of the U-shaped groove. The side wall 101 of the base 11 is provided with an inclined part 110, and the inclined part 110 is in transmission connection with the limiting component 3. The thickness of the side wall 101 corresponding to the inclined part 110 is gradually increased from top to bottom, and the arrangement of the inclined part 110 is beneficial to the stability of the roller 32 clamped between the bracket 4 and the side wall 101 and is convenient for the connecting piece 31 to take the roller 32 away from the position between the bracket 4 and the side wall 101.

Illustratively, the inclination angle of the inclined portion 110 is 3 ° to 10 °, for example, it can be selected to be 4 ° or 5 ° or 6 ° according to the outer diameter of the roller 32 and the actual requirement, so long as it is ensured that the roller 32 can be stably clamped between the inclined portion 110 and the end portion of the supporting frame 4 and is easily separated by the connecting piece 31 during the process of moving the table.

The first end surface 401 of the stay bar 41 is set to be of a cambered surface structure, so that the roller sleeve 32 is clamped conveniently, the roller sleeve 32 is separated conveniently in the moving process, and the use flexibility and smoothness of the stable supporting mechanism are improved while the supporting stability of the stay bar 41 is ensured.

In addition, a clamping tenon 42 is arranged at the top of the support rod 41, the clamping tenon 42 is arranged higher than or flush with the top of the support 12 and used for limiting the support rod 41, so that the bottom of the second end of the support rod 41 is always lower than the bottom of the first end of the support rod 41, and the support rod 41 is prevented from rotating excessively around the support 12 and cannot play a stable supporting role.

In order to avoid excessive abrasion to the end part of the stay bar 41 in the using process, avoid noise, increase of vibration reduction and the like, the rubber pad 43 is arranged at the top of the first end of the stay bar 41, so that direct impact abrasion and noise between the top of the first end of the stay bar 41 and the support 12 in the moving process are effectively avoided; suitably, a foot pad 44 is disposed at the bottom of the second end of the supporting rod 41, so as to protect the second end of the supporting rod 41.

In the present embodiment, each set of elastic connections 6 comprises a pin 61 and two torsion springs 62. In order to ensure stable and balanced connection between the support 4 and the support 12, a U-shaped groove 121 is formed in the bottom of the support 12, the end of the support 4 is located in the U-shaped groove 121, torsion springs 62 are respectively arranged on two sides of the support 4 and between the support 4 and two walls of the U-shaped groove 121, and the pin 61 simultaneously penetrates through the support 12, the support 4 and the torsion springs 62 on two sides of the support 4. The torsion spring 62 is sleeved on the pin shaft 61, a first end of the torsion spring 62 is fixedly connected with the support 4, and a second end of the torsion spring 62 is fixedly connected with the support 12.

After the first group of supporting frames 4 fall to the ground n (n is more than or equal to 0) unit length, the second group of supporting frames 4 fall to the ground … … until the fourth group of supporting frames 4 fall to the ground. In the process of continuously descending the table, the table drives the connecting sheet 31 to move downwards by pressing the limiting pile 2 downwards, and further presses the roller sleeve 32 to move downwards; until the roller 32 is pressed between the first end surface 401 of the stay 41 and the inclined portion 110 of the side wall 101 of the base 11.
