[0023] This utility model embodiment provides a portable support frame that can be used for high-altitude operations.
[0024] Please see Figure 1 and Figure 2 The system includes a support platform 1, with a unidirectional motor 2 fixedly connected to one side of the support platform 1. The output shaft of the unidirectional motor 2 is fixedly connected to a bidirectional lead screw 3. The unidirectional motor 2 can effectively provide sufficient power support for the stable rotation of the bidirectional lead screw 3. The unidirectional motor 2 is existing technology.
[0025] Please see Figure 2 The outer circumferential surface of the bidirectional lead screw 3 is rotatably connected to the inner wall of the support frame platform 1. The support frame platform 1 can effectively support the bidirectional lead screw 3 and apply a control effect to ensure that the bidirectional lead screw 3 can rotate in place. The threads at both ends of the bidirectional lead screw 3 are opposite. The design of the threads at both ends of the bidirectional lead screw 3 can effectively drive the two strip toothed plates 4 to move relative to each other.
[0026] Please see Figure 2 , Figure 3 and Figure 4 The outer circumferential surface of the bidirectional lead screw 3 is threadedly connected to the inner wall of the toothed plate 4. The tight fit between the bidirectional lead screw 3 and the toothed plate 4 allows the toothed plate 4 to move effectively when it rotates. A control bar 16 is fixedly connected to one side of the toothed plate 4. The control bar 16 is slidably connected to the inner wall of the support frame platform 1. The purpose of setting the control bar 16 is to effectively ensure the stability of the toothed plate 4, so that the toothed plate 4 can move horizontally within the support frame platform 1.
[0027] Please see Figure 2 and Figure 4 The teeth on the top of the strip toothed plate 4 mesh with the teeth on the outer circumference of the planar gear 5. The cooperation between the strip toothed plate 4 and the planar gear 5 can effectively achieve the effect of force transmission. That is, the strip toothed plate 4 moves and drives the planar gear 5 to rotate. The inner wall of the planar gear 5 is fixedly connected to the outer circumference of the linkage rod 6, and the planar gear 5 and the linkage rod 6 maintain the linkage effect.
[0028] Please see Figure 2 and Figure 4 A linkage support block 7 is fixedly connected to the outer circumference of the linkage rod 6. The linkage rod 6 can effectively drive the linkage support block 7 to rotate at a fixed point. At the same time, the linkage support block 7 can effectively support the subsequent components. A one-way motor 8 is fixedly connected to the inner wall of the linkage support block 7. A one-way lead screw 9 is fixedly connected to the output shaft of the one-way motor 8. The one-way motor 8 can effectively provide sufficient power support for the rotation of the one-way lead screw 9. The one-way motor 8 is existing technology.
[0029] Please see Figure 4 The outer circumferential surface of the one-way screw 9 is threadedly connected to the inner wall of the linkage ring 10. The tight fit between the one-way screw 9 and the linkage ring 10 allows the linkage ring 10 to move vertically up and down when the linkage ring 10 is restricted by subsequent components. The linkage ring 10 is rotatably connected to the linkage support rod 11, which is rotatably connected to the force-bearing block 12. The force-bearing block 12 is fixedly connected to the support rod 13. The tight fit between the linkage support rod 11 and the force-bearing block 12 causes the tilt angle of the support rod 13 to change as the linkage ring 10 moves.
[0030] Please see Figure 4 There are three support rods 13 in total. The other end of each of the three support rods 13 is rotatably connected to the force-bearing ring 15. The arrangement of the three support rods 13 allows for better contact with the ground, thereby supporting the support frame platform 1 and ensuring the stability of the support frame platform 1. The force-bearing ring 15 is fixedly connected to the bottom of the linkage support block 7. One end of each of the three support rods 13 is fixedly connected to a force-bearing base 14. The arrangement of the force-bearing base 14 prevents the support rods 13 from hitting the ground.
[0031] Working principle: When the support frame needs to be moved, the unidirectional motor 8 is started first, driving the unidirectional screw 9 to rotate. At this time, because the linkage support rod 11, which is connected to the linkage ring 10, is restricted by the force-bearing block 12 and the support rod 13 in sequence through the force-bearing block 12 and the support rod 13, the rotation of the unidirectional screw 9 will drive the linkage ring 10 to rise. The linkage ring 10 pulls the force-bearing block 12 through the linkage support rod 11, so that the three support rods 13 together with the force-bearing base 14 are closed. Then, the unidirectional motor 2 is started, causing the bidirectional screw 3 to rotate within the support frame platform 1. At this time, because the control strip 16, which is connected to the toothed plate 4, is restricted by the support frame platform 1, the toothed plate 4 can only move within the support frame platform 1. The horizontal movement, coupled with the control of the linkage rod 6 connected to the planar gear 5 and the support platform 1, causes the bidirectional lead screw 3 to drive the strip toothed plate 4 to move. The strip toothed plate 4 then drives the linkage rod 6 to rotate within the support platform 1 via the planar gear 5, causing the linkage support block 7 to rotate synchronously. At this time, the linkage support block 7 will drive multiple different components to move synchronously, thereby causing the linkage support block 7 and multiple components to retract into the groove on the lower surface of the support platform 1, completing the folding operation of the support frame, thus achieving the effect of easy transportation and movement, and achieving the purpose of portable movement of the support frame. Similarly, by sequentially starting the one-way motor 2 and the one-way motor 8, the unfolding operation of the support frame can be completed, thus enabling high-altitude operations.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
