[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1

[0029] A multi-coupling point mobile scaffold with multi-environment adaptability, such as Figure 1-8 As shown, it includes a scaffolding leg 1, a first support plate 102, a sliding extension leg 2 and a sliding extension mechanism. The scaffolding leg 1 jointly supports the first support plate 102. The sliding extension leg 2 is slidably connected to the inside of the scaffolding leg 1. The sliding extension mechanism is arranged inside the scaffolding leg 1. The sliding extension mechanism is used to adjust the extended length of the sliding extension leg 2, so as to control the height of the scaffolding rise, and at the same time enable the scaffolding to adapt to road surfaces in different states.

[0030] When using the scaffold, place the scaffold at a designated location, and then use the sliding extension mechanism to adjust the extended length of the sliding extension leg 2 to adjust the height of the first support plate 102. When the ground is uneven, the entire scaffold is stabilized on the ground by adjusting the extended length of the sliding extension leg 2. Four sets of identical sliding extension mechanisms adjust the corresponding sliding extension legs 2 respectively, so that the device can always keep the first support plate 102 in a horizontal state in various terrains, thereby improving construction efficiency.

[0031] like Figure 2 As shown, the sliding extension mechanism includes a first connecting rod 101, a connecting frame 201, a first spring 202, a fixing plate 203, a limiting block 204, a second spring 205 and a limiting fixing assembly. The top of the scaffolding leg 1 is fixedly connected to the first connecting rod 101, and the connecting frame 201 is fixed to the top of the sliding extension leg 2. The fixing plate 203 is fixed inside the first connecting rod 101, and the first spring 202 is fixed between the fixing plate 203 and the connecting frame 201. The two ends of the first spring 202 are respectively fixed to the fixing On the plate 203 and the connecting frame 201, a limit block 204 is slidably connected inside the connecting frame 201, a second spring 205 is connected between the limit block 204 and the connecting frame 201, two ends of the second spring 205 are respectively fixed on the limit block 204 and the connecting frame 201, the limit block 204 is slidably connected to the scaffolding leg 1, and the fixed limit assembly is installed on the outside of the sliding extension leg 2. After the sliding extension leg 2 is extended from the scaffolding leg 1, the fixed limit assembly can fix the position of the sliding extension leg 2.

[0032] When it is necessary to adjust the extension length of the sliding extension leg 2, first push the limit block 204 into the connecting frame 201, the limit block 204 will compress the second spring 205, and then pull out the fixed limit assembly, the sliding extension leg 2 will be pushed downward by the first spring 202 until the sliding extension leg 2 contacts the ground, and the sliding extension leg 2 is fixed by the limit fixing assembly, so as to realize the function of controlling the extension length of the sliding extension leg 2. When use is finished, first remove the limit fixing assembly from The scaffolding leg 1 is pulled out, and then the sliding extension leg 2 is pushed back into the scaffolding leg 1. When the limit block 204 returns to the initial position, the second spring 205 will push the limit block 204 out of the connecting frame 201, and the limit block 204 will be stuck in the scaffolding leg 1. At this time, the limit fixing component is inserted into the scaffolding leg 1, and the sliding extension leg 2 will be doubly restricted by the limit block 204 and the fixed limit component to prevent the sliding extension leg 2 from slipping out of the scaffolding leg 1.

[0033] like Figure 2 As shown, the limit fixing assembly includes sand 206, an L-shaped connecting plate 3, a baffle 301, a sliding card plate 302, a first sliding card block 303, a guide rod 304 and a third spring 305. A plurality of limit card slots 1001 are provided on the scaffolding leg 1. The connecting frame 201 is filled with sand 206. The L-shaped connecting plate 3 is slidably connected to the outer side of the sliding extension leg 2. The baffle 301 is slidably connected to the L-shaped connecting plate 3. The baffle 301 can prevent the sand 206 from sliding. 06 leaks out, a sliding card plate 302 is slidably connected to the guide rod 304 on the baffle 301, a third spring 305 is fixed between the sliding card plate 302 and the baffle 301, two ends of the third spring 305 are respectively fixed on the sliding card plate 302 and the baffle 301, the third spring 305 is sleeved on the outside of the guide rod 304, the sliding card plate 302 can be inserted into the sand 206 in the connecting frame 201, and the sliding card plate 302 is slidably connected to the first sliding block 303.

[0034] Before controlling the sliding extension leg 2 to extend, first pull the sliding card plate 302 out of the limiting card slot 1001 at the top of the scaffolding leg 1, and the sliding card plate 302 will slide along the guide rod 304 and stretch the third spring 305. When the sliding card plate 302 is pulled out of the limiting card slot 1001 on the scaffolding leg 1, push the first sliding card block 303 downward, and the first sliding card block 303 will abut against the outer side of the guide rod 304, so as to prevent the sliding card plate 302 from being brought back to the limiting card slot 1001 in advance by the third spring 305. After the sliding card plate 302 is pulled out of the limiting card slot 1001, the sliding extension leg 2 will be ejected from the scaffolding leg 1 by the first spring 202. When the sliding extension leg 2 contacts the ground, adjust the positions of the baffle plate 301 and the sliding card plate 302. When the scaffolding leg 1 is in the locked state, the first stopper 303 is pressed against the stopper 304, and the stopper 303 is pressed against the stopper 304 to thereby stop the scaffolding leg 1 from being locked.

[0035] like Figure 1-2 As shown, a U-shaped limiting rod 207 is also included, and the U-shaped limiting rod 207 is fixed inside the scaffolding leg 1.

[0036] When the sliding extension leg 2 slides out of the scaffolding leg 1, the U-shaped limiting rod 207 can limit the sliding extension leg 2 to prevent the sliding extension leg 2 from escaping from the bottom of the scaffolding leg 1, thereby achieving the function of limiting the maximum extension distance of the sliding extension leg 2.

[0037] Example 2

[0038] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a retractable movable mechanism, which includes a fixed rod 4, a sliding frame 401, a fourth spring 402, a sliding rod 403 and a roller 404. The fixed rod 4 is slidably connected in the sliding groove of the two sliding extension legs 2 on the same side, and the sliding frame 401 is slidably connected on the fixed rod 4. The fourth spring 402 is connected between the sliding frame 401 and the fixed rod 4, and both ends of the fourth spring 402 are respectively fixed on the fixed rod 4 and the sliding frame 401. The sliding rod 403 is slidably connected between the two L-shaped connecting plates 3 on the same side, and the two ends of the sliding rod 403 are rotatably connected to the rollers 404.

[0039] When the four sliding extension legs 2 are extended to the same length or are all in the initial position, the operator can push the sliding frame 401 in the direction of the fixed rod 4. At this time, the sliding rod 403 will slide downward along the slideway on the L-shaped connecting plate 3. When the sliding rod 403 slides to the lowest point, the sliding frame 401 is released, and the sliding frame 401 is reset under the action of the fourth spring 402. The sliding rod 403 will be stuck in the groove on the sliding frame 401. At this time, the four rollers 404 are all in contact with the ground, and the operator can push the scaffold to move. After moving to the corresponding position, the bottom of the sliding frame 401 is pushed to slide in the direction of the fixed rod 4, and the sliding rod 403 is lifted upward. When the sliding rod 403 moves to the top of the sliding frame 401, the sliding frame 401 is released, and the fourth spring 402 will bounce the sliding frame 401 back to its original position. At this time, the sliding rod 403 is released again, and the sliding rod 403 will fall to the top of the sliding frame 401, which can realize the function of facilitating the movement of the scaffold as a whole.

[0040] like Figure 6-8 As shown, it also includes a top lifting mechanism, which includes a folding bracket 5, a second connecting rod 501, a sliding block 502, a second support plate 6, a hook 601, a support rod 602, a second sliding block 603, a fixing frame 604, a fifth spring 605 and a locking mechanism. The top of the first connecting rod 101 is hinged with a folding bracket 5, and a plurality of sliding blocks 502 are slidably connected to the first support plate 102. A second connecting rod 501 is hinged between the sliding blocks 502 and the corresponding folding brackets 5. The two folding brackets 5 on the same side slide between each other. A support rod 602 is dynamically connected, and through holes are provided at both ends of the support rod 602. Fixing frames 604 are fixed in the through holes at both ends of the support frames. Both ends of each fixing frame 604 are slidably connected to a second sliding block 603 through a fifth spring 605. The support rod 602 is clamped on the two folding brackets 5 on the same side through the second sliding block 603. The second support plate 6 is clamped on the two support rods 602 through the hooks 601 on both sides thereof. The locking mechanism is installed on the first support plate 102, and the locking mechanism is used to lock and limit the position of the folding bracket 5.

[0041] When the height of the scaffolding is not enough, the folding bracket 5 can be raised, and the folding bracket 5 drives the sliding block 502 to slide through the second connecting rod 501, and then the sliding block 502 is clamped by the locking mechanism to keep the folding bracket 5 in a vertical state. Three through holes are provided on the folding bracket 5, and the support rod 602 can be placed in the corresponding through holes as needed. When placing the support rod 602, first push the second sliding block 603 at one end of the support rod 602 back into the groove, and then insert one end of the support rod 602 into the folding bracket 5. When the second sliding block 603 completely passes through the folding bracket 5, the second sliding block 603 will slide outwards under the elastic force of the fifth spring 605, and the support rod 602 is clamped in the two folding brackets 5 through the two groups of second sliding blocks 603 at both ends of the support rod 602. After both support rods 602 are all stuck on the folding bracket 5, the hook 601 on the second support plate 6 is aligned with the support rod 602, so that the two ends of the second support plate 6 are clamped on the support rod 602, so as to fix the second support plate 6 and raise the height of the working surface. After use, the second support plate 6 is first removed from the support rod 602, and then the support rod 602 is taken out by first pushing the second sliding block 603 back to the support rod 602, and then the locking mechanism is opened, so that the sliding block 502 drives the second connecting rod 501 to move, and the folding bracket 5 is rotated around the hinge point through the second connecting rod 501. When the sliding block 502 moves to the outermost edge of the first support plate 102, the folding bracket 5 just rotates 90 degrees and becomes horizontal, thereby realizing the function of raising the working plane as a whole.

[0042] like Figure 7 As shown, the locking mechanism includes a fixed frame 503, a sliding limit block 504 and a limit column 505. Multiple fixed frames 503 are fixed on the top of the first support plate 102. A sliding limit block 504 is slidably connected in each fixed frame 503. The sliding limit block 504 is slidably connected in the limit column 505. The limit column 505 is clamped on the top of the first support plate 102.

[0043] When the folding bracket 5 needs to be lowered, the limiting column 505 is first pulled out from the top of the first support plate 102, and then the sliding limit block 504 and the limiting column 505 are taken out from the fixed frame 503 to achieve the function of locking the position of the folding bracket 5.

[0044] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
