The choice of steel pipe connection method and technique of scaffolding also plays a vital role in the stability and safety of the entire scaffolding. Fastener connection is a common connection method of scaffolding. Scaffolding connected by fasteners has the advantages of strong anti-slip ability, strong anti-deformation ability and strong anti-detachment ability. In the prior art, the fastener is mainly composed of two sub-fasteners, which are mainly composed of a base and a gusset plate. One end of the base and the gusset plate are rotatably connected to each other, and the other end of the base and the gusset plate is fixed by bolts. When installing the scaffolding, it is necessary to fix the longitudinal rods, cross rods and vertical rods. The fasteners can fix the two adjacent longitudinal rods, cross rods and vertical rods. It is necessary to separate the base and the gusset plate first, and then put the longitudinal rods, cross rods and vertical rods between the base and the gusset plate, and finally buckle the base and the gusset plate and fix them with bolts and nuts. The fastener connection in the prior art has defects in practical applications, as follows: in actual use, when installing the scaffolding, it is necessary to screw nuts onto the bolts to fix the base and the gusset plate; when dismantling the scaffolding, it is necessary to unscrew the nuts on the bolts to separate the base and the gusset plate; this results in low efficiency for construction workers when installing and dismantling the scaffolding, and the cumbersome operations during high-altitude operations increase the safety risks of construction workers.

The base 2 is rotatably connected to the buckle plate 3, and the base 2 and the buckle plate 3 can be buckled to be fixed on the scaffolding; the base 2, a rotating roller 5 is rotatably installed on the base 2, a connecting rod 4 is installed on the rotating roller 5, the connecting rod 4 is axially provided with a plurality of annular locking grooves 11, the connecting rod 4 is axially provided with an unlocking groove 12, and the unlocking groove 12 communicates with the plurality of locking grooves 11; the buckle plate 3, the buckle plate 3 is provided with a through groove 6, and the connecting rod 4 can pass through the through groove 6; the locking sleeve 7, the locking sleeve 7 can be engaged with the locking groove 11, the locking sleeve 7 can cooperate with the unlocking groove 12, and the outer diameter of the locking sleeve 7 is greater than the groove width of the through groove 6.

[0023] In this embodiment, the fastener mainly consists of two sub-fastener components 1. The two sub-fastener components 1 are connected to each other, and both can be used for fixing the scaffolding. The fastener-type scaffolding mainly consists of vertical poles, longitudinal poles, and crossbars. The two sub-fastener components 1 can fix adjacent vertical poles and longitudinal poles, or adjacent vertical poles and crossbars, or adjacent crossbars and longitudinal poles, so as to realize the installation of the scaffolding. The sub-fastener component 1 consists of a base 2 and a buckle plate 3. One end of the base 2 is hinged to the buckle plate 3. After the base 2 and the buckle plate 3 are buckled, a cylindrical cavity is formed, which can hold the vertical pole, longitudinal pole, or crossbar in the cylindrical cavity. After the base 2 and the buckle plate 3 are opened, the vertical pole, longitudinal pole, or crossbar can be taken out. Please refer to Figure 1 Both ends of the rotating roller 5 are rotatably connected to the base 2. A connecting rod 4 is installed on the rotating roller 5. When the rotating roller 5 rotates, it can drive the connecting rod 4 to rotate. A through groove 6 is opened at the end of the buckle plate 3. When the buckle plate 3 is buckled with the base 2, the connecting rod 4 passes through the through groove 6. The locking sleeve 7 is sleeved on the connecting rod 4 and is clamped with a preset locking groove 11, so as to install the scaffolding. The locking sleeve 7 can be selected to cooperate with the corresponding locking groove 11 according to the size of the scaffolding. For example, when the size of the scaffolding is large, the locking sleeve 7 can cooperate with the locking groove 11 farther away from the base 2; when the size of the scaffolding is small, the locking sleeve 7 can cooperate with the locking groove 11 closer to the base 2; and the position of the connecting rod 4 is adjusted by rotating the rotating roller 5 according to the size of the scaffolding. After the locking sleeve 7 is sleeved on the connecting rod 4, the connecting rod 4 can vertically pass through the through groove 6 in the positive direction, and the locking sleeve 7 can completely press against the surface of the buckle plate 3, avoiding the problem of looseness between the base 2 and the buckle plate 3. When installing the scaffolding, there is no need to screw nuts onto bolts. The construction workers only need to engage the locking sleeve 7 with the corresponding locking groove 11 to fix the base 2 and the buckle plate 3, greatly reducing the working intensity of installing the scaffolding and eliminating many cumbersome operations, reducing the safety risk of construction workers during high-altitude operations. When disassembling the scaffolding, there is no need to unscrew the nuts on the bolts. The construction workers only need to rotate the locking sleeve 7 and rotate the locking sleeve 7 along the annular locking groove 11. When the clamping part of the locking sleeve 7 clamped in the locking groove 11 rotates to the unlocking groove 12, the base 2 and the buckle plate 3 can be separated. This greatly reduces the working intensity of disassembling the scaffolding and eliminates many cumbersome operations, reducing the safety risk of construction workers during high-altitude operations.

[0024] Furthermore, in the present utility model, an elastic member and a locking member 15 with a wedge-shaped structure are further included; an installation groove 13 is provided on the inner side wall of the locking sleeve 7. One end of the elastic member is connected to the inner side wall of the installation groove 13, and the other end of the elastic member is connected to the locking member 15; in the locked state, the locking member 15 is snapped into a preset locking groove 11, and the base 2 is buckled with the buckle plate 3; in the unlocked state, the locking member 15 moves into the unlocking groove 12, and the base 2 is separated from the buckle plate 3.

[0025] In this embodiment, please refer toFigure 2 The locking sleeve 7 is a column with a through hole in the middle. An installation groove 13 is provided on the inner side wall of the locking sleeve 7. An elastic member is installed in the installation groove 13. The elastic member is connected to the locking member 15. The wedge-shaped structure of the locking member 15 faces outside the installation groove 13. When installing the scaffolding, place the scaffolding between the base 2 and the buckle plate 3, and then rotate the base 2 and the buckle plate 3 towards each other to clamp the scaffolding between them. Rotate the connecting rod 4 to vertically pass through the through groove 6, sleeved the locking sleeve 7 on the connecting rod 4 and move it towards the buckle plate 3. The locking member 15 on the inner side wall of the locking sleeve 7 is abutted by the outer side wall of the connecting rod 4. The locking member 15 is pressed into the installation groove 13 and the elastic member is compressed. When the locking member 15 moves to the locking groove 11, the locking member 15 is pushed into the locking groove 11 by the elastic member. After the locking member 15 is stuck in the locking groove 11, the locking sleeve 7 can continue to move towards the buckle plate 3. During the process of the locking sleeve 7 moving towards the buckle plate 3, the lower side of the locking member 15 (the lower side of the locking member 15 is a wedge-shaped structure) abuts against the locking groove 11, and the locking member 15 is pressed into the installation groove 13, so that the corresponding locking groove 11 can be selected according to the size of the scaffolding. After the locking member 15 is stuck in the locking groove 11, the locking sleeve 7 cannot move in the direction away from the buckle plate 3. The upper side of the locking member 15 (the upper side of the locking member 15 is a non-wedge-shaped structure) abuts against the locking groove 11, and the locking member 15 will not be pressed into the installation groove 13. Therefore, after the scaffolding is fixed, problems such as loosening or falling off of the scaffolding will not occur. When disassembling the scaffolding, rotate the locking sleeve 7 relative to the connecting rod 4. The locking member 15 can rotate in the corresponding locking groove 11 until the locking member 15 rotates to the unlocking groove 12. The locking groove 11 no longer limits the locking member 15. At this time, the locking sleeve 7 can be taken out from the connecting rod 4, and then the base 2 and the buckle plate 3 are separated, so as to disassemble the scaffolding.

[0026] Further, in the present utility model, the elastic member includes a return spring 14. One end of the return spring 14 is connected to the surface wall of the installation groove 13, and the other end of the return spring 14 is connected to the locking member 15.

[0027] In this embodiment, the installation groove 13 is connected to the locking member 15 through the return spring 14. The two sides of the locking member 15 are slidably matched with the surface wall of the installation groove 13. The return spring 14 can press the locking member 15 into the locking groove 11, so as to fix the scaffolding. The side wall of the connecting rod 4 can abut against the locking member 15, press the locking member 15 into the installation groove 13 to compress the return spring 14, so that the locking sleeve 7 can move into the corresponding locking groove 11. Moreover, the elastic ability of the return spring 14 is excellent and the service life is long.

[0028] Further, in the present utility model, blocking members 9 are installed on both sides of the edge of the through groove 6. The blocking members 9 are used for limiting the locking sleeve 7.

[0029] In this embodiment, when installing the scaffolding, place the scaffolding between the base 2 and the buckle plate 3, and snap the base 2 and the buckle plate 3 together. The connecting rod 4 of the base 2 passes through the through groove 6 of the buckle plate 3, and finally, the locking sleeve 7 is sleeved on the preset position of the connecting rod 4, thereby realizing the fixation of the scaffolding. The blocking member 9 is installed on the edge of the through groove 6, and the blocking member 9 can limit the locking sleeve 7 to prevent the locking sleeve 7 from sliding out of the end of the through groove 6 and affecting the stability of the scaffolding.

[0030] Furthermore, in the present utility model, a rotating member 8 is installed on the outer side wall of the locking sleeve 7, and the rotating member 8 is used to drive the locking sleeve 7 to rotate.

[0031] In this embodiment, when disassembling the scaffolding, it is necessary to rotate the locking sleeve 7 and rotate the locking sleeve 7 along the annular locking groove 11. When the locking member 15 of the locking sleeve 7 engaged with the locking groove 11 rotates to the unlocking groove 12, the base 2 and the buckle plate 3 can be separated. This greatly reduces the working intensity of disassembling the scaffolding. The installation of the rotating member 8 on the outer side wall of the locking sleeve 7 makes it more convenient to rotate the locking sleeve 7.

[0032] Furthermore, in the present utility model, a rotating shaft 10 is further included, and the rotating shaft 10 is rotatably installed between the two bases 2.

[0033] In this embodiment, the base 2 is provided with a rotating groove that cooperates with the rotating shaft 10, and both ends of the rotating shaft 10 are respectively snapped into the rotating grooves of the base 2, so that the two split buckle assemblies 1 can rotate relative to each other. After the two split buckle assemblies 1 can adjust the angle, the scaffolding can be installed at any angle, and the application range is wide.

[0034] In summary, the embodiments of the present utility model provide a connecting device for a construction scaffolding. The locking sleeve 7 can be selected to cooperate with the corresponding locking groove 11 according to the size of the scaffolding. For example, when the size of the scaffolding is larger, the locking sleeve 7 can cooperate with the locking groove 11 farther away from the base 2; when the size of the scaffolding is smaller, the locking sleeve 7 can cooperate with the locking groove 11 closer to the base 2. Moreover, the position of the connecting rod 4 is adjusted by rotating the rotating roller 5 according to the size of the scaffolding. Thus, after the locking sleeve 7 is sleeved on the connecting rod 4, the connecting rod 4 can vertically pass through the through groove 6 in the positive direction, and the locking sleeve 7 can completely press against the surface of the buckle plate 3, avoiding the problem of looseness between the base 2 and the buckle plate 3. When installing the scaffolding, there is no need to screw nuts onto bolts. The construction workers only need to snap the locking sleeve 7 with the corresponding locking groove 11 to fix the base 2 and the buckle plate 3, greatly reducing the working intensity of installing the scaffolding and eliminating many cumbersome operations, reducing the safety risks of construction workers during high-altitude operations. When disassembling the scaffolding, there is no need to unscrew the nuts on the bolts. The construction workers only need to rotate the locking sleeve 7 and rotate the locking sleeve 7 along the annular locking groove 11. When the engaging portion of the locking sleeve 7 engaged with the locking groove 11 rotates to the unlocking groove 12, the base 2 and the buckle plate 3 can be separated. This greatly reduces the working intensity of disassembling the scaffolding and eliminates many cumbersome operations, reducing the safety risks of construction workers during high-altitude operations.
