[0035] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0036] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention. Example 1

[0037] See also Figure 1 - Figure 3 The mobile scaffold of the present invention comprises: four supporting columns a with universal wheels 1 installed at the bottom, a left frame 2 and a right frame 3 are formed respectively between the two supporting columns a on the left and between the two supporting columns a on the right through fixing rods b;

[0038] The left side frame 2 and the right side frame 3 are connected by a folding cross bar 7, and the left side frame 2 and the right side frame 3 can be folded by folding the folding cross bar 7;

[0039] A reinforcement frame 5 is installed between the left side frame 2 and the right side frame 3 to assist the left side frame 2 and the right side frame 3 in unfolding.

[0040] The reinforcement frame 5 includes two support rods 51 arranged in an X shape, and the centers of the two support rods 51 are rotatably connected through a rotating shaft 4. The two ends of the support rods 51 are slidably connected to the left frame 2 and the right frame 3 through hinged sliders 52 respectively.

[0041] It also includes a locking mechanism 6 for locking the angle of the support rod 51;

[0042] The locking mechanism 6 can be a locking hole provided on the slider 52 and the left frame 2 and the right frame 3 , through which a bolt or a pin rod passes through the slider 52 and is inserted and locked.

[0043] In this example:

[0044] By folding or unfolding the folding crossbar 7, the left side frame 2 and the right side frame 3 can be switched between the storage state and the use state. The setting of the reinforcement frame 5 can effectively lock the state of the left side frame 2 and the right side frame 3 after being unfolded, thereby effectively ensuring the stability of the structure. At the same time, because the reinforcement frame 5 includes two rotatably connected support rods 51 and sliders 52 installed on the support rods 51, during the switching process, the two support rods 51 in the reinforcement frame 5 will rotate with the rotating shaft 4 as the rotation point, and make the sliders 52 hinged at the ends of the support rods 51 slide on the left side frame 2 and the right side frame 3, which will not affect the switching of the left side frame 2 and the right side frame 3 between the storage state and the use state.

[0045] When the left side frame 2 and the right side frame 3 are in the unfolded state, the slider 52 can be fixed by bolts or pins, thereby fixing the distance between the left side frame 2 and the right side frame 3, effectively ensuring the stability of the structure. Example 2

[0046] See also Figure 4 - Figure 6 As a variation of the first embodiment, the difference from the first embodiment is that the locking mechanism 6 is installed on the left frame 2 or the right frame 3, and the locking mechanism 6 includes a rack 61 fixedly connected to the two sliders 52 on the same side, a gear 62 is engaged between the two racks 61, and the gear 62 is installed on the fixed rod b through the central shaft 63, and the central shaft 63 is threaded through the fixed rod b.

[0047] In this example:

[0048] By rotating the gear 62 to drive the rack 61 to move, the distance between the two sliders 52 located on the left frame 2 can be changed, so that the two support rods 51 in the reinforcement frame 5 can be rotated. The rotation of the two support rods 51 will change the distance between the left frame 2 and the right frame 3, and the central axis 63 is threaded through the fixed rod b, that is, after the central axis 63 carries the gear 62 to rotate and adjust the reinforcement frame 5, it will be locked on the fixed rod b through the self-locking property of the thread, that is, the locking mechanism 6 in this embodiment not only has the function of locking the reinforcement frame 5, but also can make the left frame 2 and the right frame 3 unfold during the locking process.

[0049] Furthermore, a limit frame 64 is fixedly installed on the fixed rod b of the central axis 63, and a limit hole for the two racks 61 to pass through is opened on the limit frame 64, and a rotating hole for installing the gear 62 is opened in the center of the limit frame 64; it can effectively limit the movable path of the rack 61 and effectively protect its rack 61 and gear 62. Example 3

[0050] See also Figure 7As a specific definition of the folding crossbar 7 in the first and second embodiments, the folding crossbar 7 includes a fixed section 71 and a folding section 72. One end of the fixed section 71 is fixedly connected to the left side frame 2, and the other end of the fixed section 71 is hinged to the folding section 72 via a hinge. The other end of the folding section 72 movably passes through the through hole provided in the right side frame 3, and a stopper 73 larger than the through hole is provided at the end of the folding section 72 away from the fixed section 71:

[0051] The folding crossbar 7 further includes a locking member 74, which is used to limit the folding of the folding crossbar 7. The locking member 74 is a threaded sleeve 741, and both the fixed section 71 and the folding section 72 are provided with threads for the threaded sleeve 741 to move.

[0052] The diameter of the through hole is larger than that of the threaded sleeve 741 , and a fitting ring adapted to the through hole is fixedly sleeved on the surface of the folding section 72 close to the limiting member 73 .

[0053] When the folding crossbar 7 is used in the above-mentioned first and second embodiments:

[0054] By rotating the folding section 72 of the folding crossbar 7 through the hinge, the folding crossbar 7 can be unfolded to a horizontal state, so that the right side frame 3 can slide on the folding crossbar 7 to unfold. After the folding crossbar 7 is unfolded to a horizontal state, the threaded sleeve 741 can be rotated between the folding section 72 and the fixed section 71 to lock the horizontal folding crossbar 7, thereby ensuring the stability of the folding crossbar 7 when the right side frame 3 moves on the folding crossbar 7.

[0055] In the first embodiment, after the folding cross bar 7 is adjusted to be locked horizontally, two people can pull the left side frame 2 and the right side frame 3 to the sides to unfold them.

[0056] In the second embodiment, after the folding crossbar 7 is adjusted to the horizontal locking position, the central shaft 63 can be rotated to cause the gear 62 to drive the rack 61 to push the slider 52 on the left side frame 2 to move, thereby causing the support rod 51 to push the right side frame 3 to move relative to the left side frame 2 and unfold. That is, using the folding crossbar 7 in the second embodiment, one person can complete the unfolding and locking of the right side frame 3 by rotating the central shaft 63, making it more convenient to use.

[0057] In this embodiment, a platform for manual standing is not described. However, in this embodiment, a platform can be formed by overlapping sheet materials on the folding cross bars 7 to form a complete scaffold; or a plurality of folding cross bars 7 can be used to form a platform. Example 4

[0058] See also Figure 8As a further variation of the third embodiment: there are multiple folding cross bars 7, wherein multiple folding cross bars 7 form a bearing platform in parallel at the upper ends of the left frame 2 and the right frame 3, and the limiting members 73 of the folding cross bars 7 in the bearing platform are fixedly connected together.

[0059] The locking member 74 in the carrying platform is a sliding sleeve 742 and a docking ring 743. Several sliding sleeves 742 in the carrying platform are connected together, and the docking ring 743 is correspondingly arranged on the folding section 72. The sliding sleeve 742 is slidably inserted into the docking ring 743 to lock the folding cross bar 7.

[0060] In this embodiment, different from the third embodiment, a platform is formed by a plurality of folding cross bars 7, and a horizontal locking of the plurality of folding cross bars 7 is formed by synchronously sliding and docking corresponding docking rings 743 through the connected sliding sleeves 742, so that the operation of the first and second embodiments is not affected, and the platform can be provided with a load-bearing platform for manual standing.

[0061] The above is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements based on the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
