[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 8 A movable and easily disassembled scaffold comprises a plurality of ladders 25 and a plurality of platforms 1 for stepping on are arranged between the ladders 25. The platforms 1 are arranged at various positions between the ladders 25 to solve the problem that the platform 1 in the middle of the ladders 25 is difficult to climb.

[0025] For this purpose, a slidable auxiliary plate 2 is set at the bottom of the platform 1. After the auxiliary plate 2 is protruded from the platform 1, it is convenient for the user to take one more step and quickly reach the platform 1. For this purpose, the auxiliary plate 2 is slidably set in the first track 3 at the bottom of the platform 1, wherein the auxiliary plate 2 includes a first slider 4, and the first slider 4 slides in the first track 3 to achieve its smooth movement.

[0026] At the same time, a slot for the auxiliary plate 2 to pass through is provided on the platform 1 to enhance the strength of the auxiliary plate 2 when it moves to the outside of the platform 1. At the same time, in order to display the automated control auxiliary plate 2, a first spring 5 is provided between the first slider 4 and the platform 1. Furthermore, the slot and the first slider 4 are both connected to the folded edge 14 of the platform 1, and the folded edge 14 is bent downward by 90° on both sides of the platform 1, that is, the auxiliary plate 2 slides horizontally in the folded plate.

[0027] At the same time, a fixed plate 6 is arranged on the folding plate, and the fixed plate 6 is hollow in matching the notch, and the rest of the part is connected to the folding edge 14, so that the auxiliary plate 2 can pass through the fixed plate 6 normally. Furthermore, in order to realize the rapid movement of the auxiliary plate 2, a first electromagnet 7 is arranged on the fixed plate 6. The first electromagnet 7 is preferably arranged at the connection between the fixed plate 6 and the folding edge 14, and the first slider 4 is preferably made of a metal material that can be magnetically adsorbed, that is, when the first electromagnet 7 is started, the first slider 4 moves to one side thereof, so as to realize the rapid outward movement of the auxiliary plate 2, and help the user take one more step to quickly enter the platform 1 from the ladder 25, thereby improving safety.

[0028] Furthermore, when the auxiliary plate 2 is moved outward, it is generally placed in the air. If it is stepped on for a long time, the service life of the auxiliary plate 2 will be short. In this regard, a support rod 11 is provided at the bottom of the auxiliary plate 2, and the support rod 11 is mainly used to strengthen the connection between the auxiliary plate 2 and the platform 1.

[0029] Specifically, the support rod 11 is connected to the auxiliary plate 2 through a rotating shaft 8, wherein a mounting groove 9 is provided at the bottom of the auxiliary plate 2, and the rotating shaft 8 is rotatably connected to the mounting groove 9. At the same time, a torsion spring 10 is provided between the rotating shaft 8 and the mounting groove 9. When the torsion spring 10 is in a stationary state, the support rod 11 is completely located in the mounting groove 9 and does not affect the movement of the auxiliary plate 2.

[0030] At the same time, an arc track 12 is arranged on the fixed plate 6, and the arc track 12 is arranged toward the outside, that is, when the support rod 11 follows the auxiliary plate 2 to move to the outside of the platform 1, the end of the support rod 11 is located at the head of the arc track 12, and at the same time, a second electromagnet 13 is arranged at the end of the arc track 12, so that when the second electromagnet 13 is started, the support rod 11 rotates along the rotating shaft 8 in the arc track 12 and is adsorbed by the second magnetic member. The support rod 11 cooperates with the fixed plate 6 and the auxiliary plate 2 to form a stable triangular structure, so as to achieve stable placement of the auxiliary plate 2.

[0031] Furthermore, it is necessary to enhance the supporting force of the support rod 11, and therefore a box body 15 is installed on the inner side of the fixed plate 6, in which an electric push rod 16 is installed, and the electric push rod 16 includes an output shaft 17, and the electric push rod 16 is obliquely arranged in the box body 15, and the inclination angle is consistent with the angle at which the support rod 11 reaches the second electromagnet 13, that is, the output shaft 17 abuts against the end of the support rod 11. At this time, after the electric push rod 16 is started, the output shaft 17 acts on the support rod 11.

[0032] Furthermore, it takes a certain amount of time for the support rod 11 to slide, because a through hole 18 is provided on the arc track 12, the output shaft 17 is provided in the through hole 18, and a baffle 19 is provided on the arc track 12, the baffle 19 slides on the arc track 12 in a matching manner, and one end of the baffle 19 is connected to the arc track 12 through a second spring 21, and the other end of the baffle 19 is protrudingly provided with a protrusion 20, when the second spring 21 is in a stationary state, the through hole 18 is covered by the baffle 19; when the support rod 11 slides, after the support rod 11 contacts the protrusion 20, it will drive the baffle 19 to overcome the movement of the second spring 21, that is, the baffle 19 no longer blocks the through hole 18, and the output shaft 17 acts on the support rod 11.

[0033] For the controlled moving auxiliary plate 2, a starting switch 22 is provided to synchronously control the first electromagnet 7, the second electromagnet 13 and the electric push rod 16. After the three groups are started synchronously, the first electromagnet 7 drives the first slider 4 to move to a suitable position, and then the second electromagnet 13 drives the support rod 11 to move. After the support rod 11 completes the movement of the baffle 19, the electric push rod 16 acts on the support rod 11 to complete the enhanced support.

[0034] At the same time, the force of the output shaft 17 varies with different weights. Due to the different weights of different users, if the thrust of the electric push rod 16 is too large or too small, it will affect the auxiliary plate 2 and cannot be reasonably handled, resulting in a reduction in the life of the auxiliary plate 2.

[0035] Therefore, the electric push rod 16 also includes an adjusting device, which is arranged in the ladder 25. Further, the adjusting device includes a pressure sensor 23 and a control element 24. The larger the value of the pressure sensor 23, the greater the thrust provided by the electric push rod 16. In this regard, the pressure sensor 23 and the control element 24 are electrically connected to the electric push rod 16.

[0036] Generally, the ladder 25 includes two groups of vertical bars and several horizontal bars. The pressure sensor 23 can be installed on the horizontal bars, and the control element 24 can be installed on the vertical bars. At the same time, the control element 24 can be a PLC controller or a central processing unit in the prior art. Generally speaking, after the maximum value of the pressure sensor 23 is transmitted to the control element 24, the control element 24 controls the pushing force of the electric push rod 16 to maintain a reasonable pushing force to ensure that the user can step stably on the auxiliary board 2.

[0037] Furthermore, the auxiliary board 2 can be set on both sides of the platform 1. Only after the same components are set on the opposite side, the direction of movement of the auxiliary board 2 can be realized by starting the first electromagnet 7 and the second electromagnet 13 on the other side through different starting switches 22, thereby improving the suitability for users with different stepping habits.

[0038] Meanwhile, the start switch 22 can be arranged on the ladder 25. When the user climbs to a suitable position, the start switch 22 can be directly controlled. After the user transfers to the platform 1, the start switch 22 can be turned off to automatically retract the auxiliary board 2.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
