[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides a technical solution, such as Figure 1-Figure 6As shown; a scaffolding connection device with a leveling function, including a square connection frame 1, the square connection frame 1 is sleeved on the upper end of the vertical pipe, and also includes: a connecting sleeve 11, which is arranged at the center of the upper and lower ends of the square connection frame 1; an arc-shaped extrusion seat 12, which is located at the upper and lower ends of the square connection frame 1 and on both sides of the connecting sleeve 11, and an adjusting screw 121 is movably installed at one end of its outer surface, the adjusting screw 121 is threadedly connected to the square connection frame 1 and extends out of the square connection frame 1, and an adjusting handle 122 is installed at one end of the adjusting screw 121.

[0031] In the embodiment of the utility model, by setting the connecting sleeve 1, when the square connecting frame 1 is connected to the upper and lower vertical pipes, the vertical pipe installation is more stable and the shaking thereof is reduced, and the connection strength between the square connecting frame 1 and the vertical pipes can be improved.

[0032] In the embodiment of the utility model, the arc-shaped extrusion seat 12 is pressed against the outer surface of the vertical tube by rotating the adjusting screw 121, so that the vertical tube can be quickly fixed to the square connecting frame 1, thereby reducing the operating difficulty of the device and making the installation of the square connecting frame 1 and the vertical tube faster and more convenient.

[0033] The limit baffles 13 are located on both sides of the center of the inner side surface of the square connecting frame 1, and are symmetrically distributed along the vertical center line of the square connecting frame 1, and are located between the arc extrusion seats 12 on the upper and lower sides; the upper baffle 14 is arranged at the upper part of the square connecting frame 1, and its two ends are respectively located between the two limit baffles 13, and are in sliding contact with the limit baffles 13 and the square connecting frame 1, and a positioning sleeve 141 is installed on its upper surface, and a fixing screw 142 is installed on its lower surface; the lower baffle 15 is arranged at the lower part of the square connecting frame 1 and is fixedly connected to the square connecting frame 1, and a positioning sleeve 141 identical to that on the upper baffle 14 is arranged on its lower surface, and an adjusting sleeve 151 is arranged on its upper surface and connected through a bearing, and the adjusting sleeve 151 is sleeved on the fixing screw 142 and threadedly connected to the fixing screw 142, and an annular handle 152 is installed on the upper end of the outer surface of the adjusting sleeve 151.

[0034] In the embodiment of the utility model, by using the lower baffle 15, the square connection frame 1 can be quickly placed on the upper end of the vertical pipe through the positioning sleeve 141, and the stability of the installation of the square connection frame is ensured.

[0035] In the embodiment of the utility model, the threaded cooperation of the fixing screw 142 and the adjusting sleeve 151 allows the staff to adjust the installation height of the vertical pipe according to the actual situation, so that after the vertical pipe is installed, its upper end is flush with the height, so as to facilitate the subsequent construction of the scaffolding and avoid the problem that the upper end of the vertical pipe is uneven, which causes the operating position of the staff to change and affects the construction efficiency of the scaffolding, thereby ensuring the rapid construction of the scaffolding; at the same time, the fixing screw 142 and the adjusting sleeve 151 are used to support the vertical pipe, which can ensure the stability of the installation of the vertical pipe.

[0036] In the embodiment of the utility model, the upper baffle 14 is limited by the limiting baffle 13 to prevent it from being offset, so as to ensure the accuracy of the vertical pipe connection, avoid the problem of offset between the two vertical pipes, and ensure the stability of the scaffold connection.

[0037] The strip sliding groove 16 is opened at the center of the two side surfaces of the outside of the square connecting frame 1, and strip bolt holes 161 are opened on the two side surfaces; the L-shaped sliding seat 17 is slidably inserted in the strip sliding groove 16, and fixing bolts 171 are installed on the two side surfaces. The fixing bolts 171 are movably inserted in the strip bolt holes 161, and a locking nut 172 is installed on the fixing bolt 171. The locking nut 172 is located outside the square connecting frame 1, and a transverse tube connecting mechanism 173 is set at one end. The transverse tube connecting mechanism 173 is composed of two arc-shaped clamping plates 1731 connected by bolts and nuts. The arc-shaped clamping plates 1731 are connected to one end of the L-shaped sliding seat 17 through a rotating seat.

[0038] In the embodiment of the utility model, the strip sliding groove 16 is arranged so that the L-shaped sliding seat 17 can be slid up and down and adjusted, and then the L-shaped sliding seat 17 can be adjusted to a suitable position to facilitate the connection between the cross tube connecting mechanism 173 and the cross tube, and ensure the levelness of the cross tube after connection, so as to avoid deformation of the cross tube during connection, which affects the stability of the scaffolding construction.

[0039] As a scaffold connection device with a leveling function of the utility model, the inner diameter of the connection sleeve 11 is the same as the inner diameter of the arc-shaped extrusion seat 12, which ensures the stability of the insertion of the vertical pipe and the square connection frame 1 to avoid shaking.

[0040] As a scaffolding connection device with a leveling function of the utility model, the inner diameter of the positioning sleeve 141 is larger than the inner diameters of the connecting sleeve 11 and the arc-shaped extrusion seat 12, which facilitates the positioning sleeve 141 to be installed on the vertical pipe, so that it can be quickly installed on the vertical pipe or supported on the bottom of the vertical pipe, avoiding the vertical pipe from contacting the outer wall of the positioning sleeve 141, resulting in unstable scaffolding construction.

[0041] As a scaffold connection device with a leveling function of the utility model, the strip sliding groove 16 is located between two adjusting screws 121 on the same side, and the cross tube connection mechanism 173 clamps the cross tube horizontally, ensuring the horizontal connection of the cross tube, making the scaffolding construction more firm and stable.

[0042] When the utility model is used specifically, when the staff finds that there is an obvious height difference between the upper ends of multiple vertical pipes when building a scaffold, the staff takes out the device and puts the square connection frame 1 on the vertical pipe with a lower upper end, so that the vertical pipe is inserted into the connection sleeve 11 at the lower end of the square connection frame 1, and then it is inserted into the positioning sleeve 141 on the lower surface of the lower baffle 15. Then the staff manually twists the two adjustment handles 122 at the bottom to drive the adjustment screw 121 to rotate and make the arc-shaped extrusion seat 12 approach the outer surface of the vertical pipe. Then, by squeezing the vertical pipe, the square connection frame 1 is fixed to the vertical pipe. Then, the staff inserts the vertical pipe to be installed later from the connection sleeve 11 at the upper end of the square connection frame 1 into the square connection frame 1, and inserts the lower end of the vertical pipe into the positioning sleeve 141.

[0043] Subsequently, the staff adjusts the height of the upper baffle 14 by measuring the height difference between the position of the upper baffle 14 and the lower ends of the vertical pipes installed above other vertical pipes, and by rotating the annular handle 152, the staff rotates the adjusting sleeve 151, and uses the threaded connection between the adjusting sleeve 151 and the fixing screw 142. When the upper end of the upper baffle 14 is roughly flush with the lower ends of the vertical pipes installed above other vertical pipes, the annular handle 152 can be stopped from rotating, and the two upper adjusting handles 122 can be manually twisted to make the two upper arc-shaped extrusion seats 12 squeeze and fix the vertical pipes above the square connecting frame 1. At this time, the vertical pipes are installed.

[0044] Finally, the staff manually pushes the L-shaped sliding seat 17 to slide up and down in the strip sliding groove 16 to adjust the position of the cross tube connecting mechanism 173, and observes whether the cross tube is horizontal by inserting the cross tube into the cross tube connecting mechanism 173. When the L-shaped sliding seat 17 is adjusted to the appropriate position, the staff can use a wrench to turn the locking nut 172 to fix the L-shaped sliding seat 17 to the square connecting frame 1, and finally use tools to tighten the bolts and nuts on the cross tube connecting mechanism 173 so that the arc-shaped clamping plate 1731 clamps the cross tube.
