[0011] In one embodiment, the guide block is provided with a guide groove, and the second push rod is slidably connected to the guide groove of an adjacent guide block.

[0012] In one embodiment, a movable groove is formed on a side of the second push rod adjacent to the arc frame, and the arc frame is movably connected to the movable groove of the adjacent second push rod.

[0013] In one of the embodiments, a sponge pad is further included. The sponge pad is sleeved on the outer wall of the locking frame, and a rubber pad is fixedly connected to the bottom of the support frame.

[0014] Compared with the prior art, the present invention has the following advantages: The invention realizes the function of self-adapting to the ground and ensures that the scaffold can remain stable on any terrain by the coordinated work of the locking frame, the supporting frame and the pressing block so that the supporting frame can automatically adjust its position according to the ground height and contact the ground.

[0015] The present invention squeezes the pressing block by the locking frame to swing toward the compression spring, so that the sliding teeth are locked into the fixed teeth, which not only fixes the position of the support frame, but also applies force to lock the locking frame itself to prevent it from moving easily, thereby ensuring the stability of the entire system.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0033] Embodiment 1: A scaffolding position stabilizing clamping device for construction, such as Figure 1-Figure 6 As shown, it includes a connecting pipe 101, the outer part of the connecting pipe 101 is slidably connected to a support frame 102 in the up-down direction, the upper part of the connecting pipe 101 is threadedly connected to a fastening bolt 103, and the connecting pipe 101 can be fixedly installed on any leg of the scaffold 1011 through the fastening bolt 103, the outer wall of the connecting pipe 101 is fixedly connected to a circular array of fixed teeth 104, the upper part of the support frame 102 is slidably connected to a circular array of sliding teeth 105, and the sliding teeth 105 correspond to the fixed teeth 104 one by one, and the upper part of the support frame 102 is rotatably connected to a pressing block 201, and the pressing block 201 and the sliding teeth 105 correspond one to one, the pressing block 201 is movably connected with the corresponding sliding tooth 105, a protrusion is arranged on the upper part of the pressing block 201, and a locking frame 202 is slidably connected to the outer part of the support frame 102 along the up and down directions, and the locking frame 202 contacts the protrusion of the pressing block 201 when sliding downward relative to the support frame 102, and when the support frame 102 touches the ground, the locking frame 202 squeezes the pressing block 201 to swing, and a spring 203 is fixed between the pressing block 201 and the support frame 102, and a first push rod 204 in a circumferential array is fixed to the bottom of the locking frame 202, and the first push rod 204 is slidably connected to the support frame 102.

[0034] The connecting pipe 101 is installed on each leg of the scaffold 1011 through the fastening bolt 103. On the side with low terrain, the locking frame 202 is pushed downward, and the locking frame 202 moves downward until it contacts the protrusion of the pressing block 201. The locking frame 202 pushes the pressing block 201 to move downward synchronously, thereby driving the support frame 102 to move downward synchronously along the connecting pipe 101, so that the support frame 102 contacts the ground, and then the locking frame 202 is pushed downward continuously. Since the support frame 102 cannot move downward continuously after touching the ground, the pressing block 201 cannot move downward continuously either. Therefore, when the locking frame 202 is pushed downward continuously, the locking frame 202 is locked. The frame 202 moves downward relative to the supporting frame 102 and the pressing block 201, so that the locking frame 202 squeezes the pressing block 201 to swing toward one side of the compression spring 203, so that the pressing block 201 pushes the sliding latch 105 to be engaged with the fixed latch 104, thereby fixing the supporting frame 102. At the same time, the pressing block 201 can also apply force to lock the locking frame 202 to prevent the locking frame 202 from moving easily. In this way, the scaffolding 1011 can be placed stably on an uneven ground to avoid the scaffolding 1011 being unstable due to uneven terrain, thereby improving the support stability of the scaffolding 1011 and thus improving the safety of the operation.

[0035] After use, the locking frame 202 is pulled upwards, and the locking frame 202 moves upwards until it is disengaged from the protrusion of the pressing block 201. The spring 203 resets and drives the pressing block 201 to swing back and forth. The pressing block 201 pulls the sliding tooth 105 to disengage from the fixed tooth 104, thereby releasing the fixation of the support frame 102. The support frame 102 is then pushed upwards to reset, and finally the fastening bolt 103 is unscrewed to remove the device from the scaffold 1011 for easy disassembly and carrying.

[0036] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, it also includes a circumferentially distributed fixed block 301, the fixed block 301 is fixedly connected to one side of the support frame 102 near the bottom, the bottom end of the first push rod 204 is rotatably connected to the connecting rod 302, and the fixed block 301 is rotatably connected to the rotating frame 303, the connecting rod 302 corresponds to the rotating frame 303 one by one, and the connecting rod 302 is rotatably connected to the corresponding rotating frame 303. After the support frame 102 touches the ground, the first push rod 204 pushes the rotating frame 303 to rotate downward ninety degrees around the fixed block 301 through the connecting rod 302 until it contacts the ground.

[0037] When the locking frame 202 and the supporting frame 102 move downward synchronously, the first push rod 204, the fixed block 301, the connecting rod 302 and the rotating frame 303 move downward synchronously as a whole. When the supporting frame 102 touches the ground, the fixed block 301 drops to the lowest position. When the locking frame 202 moves downward relative to the supporting frame 102, the locking frame 202 drives the first push rod 204 to continue to move downward. The first push rod 204 pushes the rotating frame 303 to rotate downward ninety degrees around the fixed block 301 through the connecting rod 302 until it contacts the ground, thereby increasing the supporting area and further improving the supporting stability of the scaffolding 1011.

[0038] When the locking frame 202 is pulled upward, the locking frame 202 first drives the first pushing rod 204 to move upward relative to the supporting frame 102, and the first pushing rod 204 pulls the rotating frame 303 to rotate upward ninety degrees around the fixed block 301 until it is vertically retracted through the connecting rod 302, and then continues to push the locking frame 202 upward, and the locking frame 202 moves upward by pulling the connecting rod 302 with the first pushing rod 204, thereby pulling the rotating frame 303 to move upward, and the rotating frame 303 pulls the supporting frame 102 upward and resets through the fixed block 301. In this way, there is no need to push the supporting frame 102 upward to reset, and the locking frame 202 can be reset by directly pulling it upward to the bottom.

[0039] like Figure 8 and Fig. 9 As shown, it also includes a guide block 401 corresponding to the fixed block 301, the guide block 401 is fixedly connected to the corresponding fixed block 301, the guide block 401 is provided with a guide groove, the rotating frame 303 is slidably connected to the second push rod 402, the second push rod 402 is slidably connected to the guide groove of the adjacent guide block 401, when the rotating frame 303 rotates downward around the fixed block 301, the guide groove of the guide block 401 pushes the second push rod 402 to slide, the rotating frame 303 is rotatably connected to an opening and closing frame 404 symmetrically distributed along the rotating frame 303, the opening and closing frame 404 is fixedly connected to the arc frame 403, the second push rod 402 is provided with a movable groove on one side close to the adjacent arc frame 403, the arc frame 403 is movably connected to the movable groove of the adjacent second push rod 402, and when the second push rod 402 slides, it pushes the opening and closing frame 404 to swing open through the movable groove.

[0040] During the process of the rotating frame 303 rotating downward by ninety degrees around the fixed block 301 until it contacts the ground, the rotating frame 303 drives the second push rod 402, the arc frame 403 and the opening and closing frame 404 to rotate downward by ninety degrees as a whole, so that the opening and closing frame 404 also contacts the ground. At the same time, under the action of the guide groove of the guide block 401, the second push rod 402 slides relative to the rotating frame 303 toward the side close to the opening and closing frame 404, and the second push rod 402 pushes the opening and closing frame 404 to swing open through the movable groove, thereby increasing the force-bearing area, thereby improving the stability of the support leg of the scaffolding 1011 located on the low-lying side of the terrain, and preventing the scaffolding 1011 from tipping over.

[0041] During the process of the rotating frame 303 rotating upward by ninety degrees around the fixed block 301 until it is vertically folded, the rotating frame 303 drives the second push rod 402, the arc frame 403 and the opening and closing frame 404 to rotate upward by ninety degrees as a whole. At the same time, under the action of the guide groove of the guide block 401, the second push rod 402 slides relative to the rotating frame 303 to the side away from the closing frame 404, and the second push rod 402 pulls the opening and closing frame 404 to swing in the opposite direction through the movable groove to close.

[0042] Embodiment 3: Based on embodiment 2, Fig.10 As shown, a sponge pad 501 is also included. The sponge pad 501 is sleeved on the outer wall of the locking frame 202. The sponge pad 501 can protect the hands when pushing and pulling the locking frame 202. A rubber pad 502 is fixed to the bottom of the support frame 102. The rubber pad 502 can be adaptively deformed to adapt to the uneven surface of the ground to improve stability. It can also increase the friction with the ground to prevent the support frame 102 from slipping or being unstable due to direct contact with the ground.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
