DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0021] As shown in Figures 1-5As shown in the figure, a self-leveling support device includes an adjustment housing 13. On both sides of the adjustment housing 13, there are respectively screwed a support rod fixing mechanism, which is used for temporarily fixing a support rod (not shown in the figure) extending into it. The adjustment housing 13 is provided with a through hole for the support rod to pass through. Inside the adjustment housing 13, there is a height limiting mechanism, which is used to adjust the support height of the support rod and keep the support rods on both sides synchronized, so as to realize the self-leveling of both sides of the support device.

[0022] The support rod fixing mechanism includes a bottom connection shell 10, an active block 12, a quick-release component, and a pressing block 16. The bottom connection shell 10 is screwed onto the adjustment housing 13 through thread fitting. The lower side of the bottom connection shell 10 is provided with an external thread that mates with the adjustment housing 13. The inside of the bottom connection shell 10 is hollow and is provided with a through hole that penetrates the upper and lower ends of the bottom connection shell 10. On the inner annular bottom wall of the bottom connection shell 10, there is also fixedly arranged a pressing block 16 that is concentric with the bottom connection shell 10. The pressing block 16 is composed of multiple arc-shaped pieces evenly arranged with the center of the through hole of the bottom connection shell 10 as the center of the circle, forming a whole circle. And on the outer side of the upper end of the arc-shaped piece, there is an inclined surface that is narrow at the top and wide at the bottom. The lower end of the quick-release component is slidably arranged on the upper end of the bottom connection shell 10. The quick-release component is in an overall annular shape and is provided with an internal thread inside. The quick-release component is threadedly connected to the active block 12. The active block 12 is composed of a connecting part and a screwing part. On the outer side of the connecting part, there is an external thread that mates with the internal thread of the quick-release component. The lower end of the connecting part is provided with an inclined surface that mates with the upper end of the arc-shaped piece of the pressing block 16 (with the same inclination angle). The screwing part is fixedly arranged above the connecting part, and the outer side is provided with anti-slip lines. There is a through hole in the middle of the active block 12, which is concentric with the pressing block 16 and the through hole of the bottom connection shell 10. A support rod (not shown in the figure) in the shape of a frustum with a wide top and a narrow bottom is placed in the through hole.

[0023] The arc-shaped piece is composed of upper and lower parts. The arc-shaped piece is made of an elastic material, and the gap between the arc-shaped pieces is set according to requirements.

[0024] When it is necessary to temporarily fix the support rod, first, adjust the extendable length of the support rod through the height limiting mechanism. Then, put the support rod into the through hole of the active block 12. The support rod passes through the active block 12, the quick-release component, the pressing block 16, and the bottom connection shell 10 in sequence. When the support rod is restricted by the height limiting mechanism and cannot move further, screw the screwing part of the active block 12. Then, the active block 12 moves downward under the action of the thread of the connecting part, so that the inclined surface at the lower end of the connecting part presses each arc-shaped piece of the pressing block 16 to squeeze the support rod inward, realizing the temporary fixation of the support rod and fixing the object placed on the support rod to the specified height.

[0025] The quick-release component includes a quick-release outer shell 11, a buckle 14, a buckle mounting seat 15, a quick-release guide rod 17 and a return spring 18; the quick-release outer shell 11 is composed of left and right parts, and is in an overall circular ring shape. The diameters of the upper and lower ends of the quick-release outer shell 11 are different. The diameter of the upper end of the quick-release outer shell 11 is smaller than the upper end of the bottom connection shell 10, and an internal thread is provided inside; the diameter of the lower end of the quick-release outer shell 11 matches the upper end of the bottom connection shell 10; a buckle mounting seat 15 is provided on the outside of the connection of the left and right parts of the quick-release outer shell 11, and a buckle 14 for connecting the left and right parts of the quick-release outer shell 11 together is provided on the buckle mounting seat 15; when the quick-release outer shell 11 is closed, it will buckle the bottom connection shell 10 to connect the two together. A quick-release guide rod 17 is fixedly provided on the cross-section of the connection of the quick-release outer shell 11 on one side, and a return spring 18 is provided outside the quick-release guide rod 17. One end of the return spring 18 is fixed on the cross-section of the connection of the quick-release outer shell 11. When the left and right parts of the quick-release outer shell 11 are connected, the other end of the quick-release guide rod 17 and the return spring 18 extend into the slot provided in the quick-release outer shell 11 on the opposite side.

[0026] After the fixing mechanism completes its work, if quick separation is required, the locked buckle 14 can be opened to disconnect the left and right parts of the quick-release outer shell 11, and under the guiding action of the quick-release guide rod 17, it is pushed by the return spring 18 to quickly complete the separation of the left and right parts, so that the active block 12 loses the thread restriction of the quick-release component, and then the active block 12 can be directly pulled out, so that each arc-shaped piece of the extrusion block 16 loses the pressure of inward extrusion, and the temporary fixing of the support rod can be quickly cancelled.

[0027] The buckle mounting seat 15 includes a main body part and a buckle seat part, which are respectively installed on both sides of the outer side connection of the left and right parts of the quick-release outer shell 11. The two parts are not connected to each other, and the main body part is provided with a buckle 14.

[0028] The height limiting mechanism includes an adjusting screw 19, a connecting rod 20, a push plate 21, a driven baffle 22, a driving baffle 23, a gear 24 and a push plate guide block 25; on both sides of the through hole inside the adjusting housing 13 for the support rod to pass through, a driven baffle 22 and a driving baffle 23 are respectively arranged, and the through hole of the support rod fixing mechanism is opposite between the driven baffle 22 and the driving baffle 23; a chute 26 is arranged at the top wall inside the adjusting housing 13, and the driven baffle 22 and the driving baffle 23 are slidably connected in the chute 26 through sliders; the push plate guide blocks 25 are symmetrically arranged on both sides of the center of the top wall inside the adjusting housing 13, and a push plate 21 is slidably arranged between the push plate guide blocks 25. The push plate 21 is integrally in an "L" shape, including a vertical section parallel to the side wall of the adjusting housing 13 and a horizontal section parallel to the top wall inside the adjusting housing 13; the adjusting screw 19 passes through the side wall of the adjusting housing 13 and is rotationally connected to the vertical section of the push plate 21, and the adjusting screw 19 is threadedly connected to the adjusting housing 13; on the left and right sides of the horizontal section of the push plate 21, connecting rods 20 are symmetrically and rotationally arranged, and the other end of the connecting rod 20 is rotationally connected to the middle position at the bottom of the driving baffle 23; both the driven baffle 22 and the driving baffle 23 adopt a "U" - shaped structure, and the distance between the two sides of the driving baffle 23 is greater than the distance between the two sides of the driven baffle 22; on the inner sides of the two sides of the driving baffle 23 and the outer sides of the two sides of the driven baffle 22, parallel racks are correspondingly arranged, and a gear 24 is meshed between the rack of the driving baffle 23 and the rack of the driven baffle 22.

[0029] When it is necessary to adjust the height of the support rod, the adjusting screw 19 is screwed by a tool, so that the push plate 21 slides under the guiding action of the push plate guide block 25, thereby pushing the connecting rod 20 to straighten or tilt, and further enabling the driving baffle 23 to move horizontally under the guiding action of the chute 26. The movement of the driving baffle 23 will synchronously drive the driven baffle 22 to move towards each other under the guiding action of the chute 26 through the cooperation of the rack and the gear, controlling the distance between the driving baffle 23 and the driven baffle 22, and further realizing the control of the minimum size of the support rod's fall; at the same time, during the adjustment process, the synchronous adjustment of the driving baffle 23 and the driven baffle 22 on both sides will be realized, and further the purpose of synchronously and automatically adjusting the heights on both sides will be achieved.

[0030] In an embodiment, the parts of the driving baffle 23 and the driven baffle 22 in contact with the support rod adopt an arc - shaped structure.
