[0052] The present invention will be further described below with reference to the accompanying drawings.

[0053] Scaffolding is a working platform erected to ensure the smooth progress of construction. As the connecting component between the steel pipes of the scaffolding, the reliability of the coupler directly affects the safety of the scaffolding.

[0054] Swivel couplers are a common type of coupler used in scaffolding, enabling the locking of two scaffolding steel pipes that intersect at any angle. In construction, it's necessary to connect and secure diagonally aligned scaffolding pipes to their adjacent (usually within 4-8cm) transverse pipes using swivel couplers. However, existing swivel couplers are of fixed length and cannot be adjusted, making them unsuitable for connecting pipes with distances of 6cm or more. Therefore, they cannot securely fasten scaffolding pipes with varying spacing.

[0055] Example 1

[0056] like Figure 1 , Figure 2 As shown, in order to solve the above-mentioned technical problems, this utility model embodiment provides a rotary fastener structure, including a first fastener part 10, a second fastener part 30, and an adjusting component 20; the first fastener part 10 is configured to fix a first steel pipe of scaffolding; the second fastener part 30 is arranged opposite to the first fastener part 10 in a first direction, and the second fastener part 30 is configured to fix a second steel pipe of scaffolding; one end of the adjusting component 20 is rotatably connected to the first fastener part 10, and the other end is rotatably connected to the second fastener part 30, and the adjusting component 20 is configured to drive the first fastener part 10 to move along the first direction, so as to change the distance between the first fastener part 10 and the second fastener part 30 in the first direction.

[0057] As can be seen from the above, by setting the rotatable first fastener part 10 and second fastener part 30, the first fastener part 10 and the second fastener part 30 can meet the installation angle requirements of the first steel pipe and the second steel pipe of the scaffold. By setting the adjustment component 20 to change the distance between the first fastener part 10 and the second fastener part 30, the distance between the first fastener part 10 and the second fastener part 30 can meet the requirements of the first steel pipe and the second steel pipe of the scaffold, ensuring that the first fastener part 10 and the second fastener part 30 can be securely connected to the first steel pipe and the second steel pipe respectively. This can meet the installation requirements of scaffold steel pipes with different spacing, and is highly flexible and practical. Users can adjust it according to the connection requirements of the scaffold steel pipes.

[0058] It should be noted that the first steel pipe can be a steel pipe on the diagonal of the scaffold, and the second steel pipe can be a horizontal steel pipe on the scaffold adjacent to the first steel pipe.

[0059] It should also be noted that, such as Figure 1 , Figure 2 As shown, the first direction is parallel to the Z direction, the second direction is parallel to the Y direction, and the third direction is parallel to the X direction.

[0060] Example 2

[0061] like Figure 1 , Figure 2 As shown, the swivel coupler structure includes a first coupler part 10, a second coupler part 30, and an adjusting component 20. The first coupler part 10 is configured to fix a first steel pipe of the scaffold. The second coupler part 30 is arranged opposite to the first coupler part 10 in a first direction, and the second coupler part 30 is configured to fix a second steel pipe of the scaffold. One end of the adjusting component 20 is rotatably connected to the first coupler part 10, and the other end is rotatably connected to the second coupler part 30. The adjusting component 20 is configured to drive the first coupler part 10 to move along the first direction, so as to change the distance between the first coupler part 10 and the second coupler part 30 in the first direction.

[0062] As can be seen from the above, by setting the rotatable first fastener part 10 and second fastener part 30, the first fastener part 10 and the second fastener part 30 can meet the installation angle requirements of the first steel pipe and the second steel pipe of the scaffold. By setting the adjustment component 20 to change the distance between the first fastener part 10 and the second fastener part 30, the distance between the first fastener part 10 and the second fastener part 30 can meet the requirements of the first steel pipe and the second steel pipe of the scaffold, ensuring that the first fastener part 10 and the second fastener part 30 can be securely connected to the first steel pipe and the second steel pipe respectively. This can meet the installation requirements of scaffold steel pipes with different spacing, and is highly flexible and practical. Users can adjust it according to the connection requirements of the scaffold steel pipes.

[0063] It should be noted that the first steel pipe can be a steel pipe on the diagonal of the scaffold, and the second steel pipe can be a horizontal steel pipe on the scaffold adjacent to the first steel pipe.

[0064] It should also be noted that, such as Figure 1 , Figure 2 As shown, the first direction is parallel to the Z direction, the second direction is parallel to the Y direction, and the third direction is parallel to the X direction.

[0065] like Figure 1 , Figure 2 As shown, in some embodiments, the adjustment component 20 includes a telescopic part 210 and a drive part 220; the two ends of the telescopic part 210 are rotatably connected to the first fastener part 10 and the second fastener part 30, respectively, and the telescopic part 210 is configured to extend and retract in a first direction; the drive part 220 is disposed at one end of the telescopic part 210 near the second fastener part 30, and the drive part 220 is configured to drive the telescopic part 210 to extend and retract, so that the first fastener part 10 moves along the first direction.

[0066] The telescopic part 210 is driven to extend and retract in the first direction by the drive part 220. The first fastener part 10 moves in the first direction with the telescopic part 210, thereby changing the distance between the first fastener part 10 and the second fastener part 30, so that it can meet the installation requirements of scaffolding steel pipes with different spacing.

[0067] like Figure 1 , Figure 2 As shown, in some embodiments, the telescopic part 210 includes a first telescopic support plate 2101, a second telescopic support plate 2102, and two scissor lifters 2103; the first telescopic support plate 2101 is rotatably connected to the first fastener part 10; the second telescopic support plate 2102 is spaced apart from the first telescopic support plate 2101 in a first direction, and the second telescopic support plate 2102 is rotatably connected to the second fastener part 30; the two scissor lifters 2103 are spaced apart in a second direction, and each scissor lifter 2103 includes a first scissor lift 2104 and a second scissor lift 2105 hinged together at their centers; wherein, the driving part 220 is disposed on the second telescopic support plate 2102, one end of the first scissor lift 2104 is hinged to the first telescopic support plate 2101 and the other end is hinged to the driving part 220, and one end of the second scissor lift 2105 is movably connected to the first telescopic support plate 2101 and the other end is hinged to the second telescopic support plate 2102.

[0068] The scissor lift 2103, which is formed by the first scissor lift 2104 and the second scissor lift 2105 hinged to each other at two centers, is opened and closed by the drive unit 220. This causes the included angle between the first scissor lift 2104 and the second scissor lift 2105 to change, which causes the telescopic part 210 to extend and retract in the first direction. This changes the distance between the first telescopic support plate 2101 and the second telescopic support plate 2102, and the movement is smooth.

[0069] It should be noted that, as Figure 1 , Figure 2 As shown, the telescopic part 210 also includes a wheel axle 2108 disposed between the two scissor arms 2103. The two ends of the wheel axle 2108 are hinged to the center of the first scissor arm 2104 and the second scissor arm 2105, thereby ensuring the stability and strength of the entire structure.

[0070] like Figure 1 , Figure 2 As shown, in some embodiments, the telescopic part 210 further includes two slide rails 2106 and two sliders 2107; the two slide rails 2106 are disposed on the first telescopic support plate 2101, and the two slide rails 2106 are arranged at intervals along the second direction; the two sliders 2107 correspond one-to-one with the two slide rails 2106 respectively, and the sliders 2107 are movably disposed on the corresponding slide rails 2106; wherein, the two scissor arms 2103 correspond one-to-one with the two sliders 2107 respectively, and one end of the second scissor arm 2105 is hinged to the corresponding slider 2107.

[0071] like Figure 1 , Figure 2 As shown, in some embodiments, the drive unit 220 includes two guide rails, a lead screw 2201, and a drive block 2202; the two guide rails are disposed on the second telescopic support plate 2102 and are spaced apart along the second direction; the lead screw 2201 is rotatably disposed on the second telescopic support plate 2102 and is located between the two guide rails; the drive block 2202 is threadedly connected to the lead screw 2201, and both ends of the drive block 2202 are movably disposed on the two guide rails; wherein, one end of the first scissor bar 2104 is hinged to the drive block 2202.

[0072] By rotating the lead screw 2201, the drive block 2202 is moved upwards in the third direction. Since one end of the first scissor bar 2104 is hinged to the drive block 2202, and the first scissor bar 2104 is hinged to the second scissor bar 2105, the first scissor bar 2104 is moved, pushing the scissor bar 2103 to open and close, causing the angle between the first scissor bar 2104 and the second scissor bar 2105 to change, and the telescopic part 210 extends and retracts. When the lead screw 2201 drives the drive block 2202 to move to the left, the slider 2107 moves accordingly. When the scissor lift 2103 moves to the left, the scissor lift 2103 closes, the angle between the first scissor lift 2104 and the second scissor lift 2105 decreases, the telescopic part 210 extends, and the distance between the first fastener part 10 and the second fastener part 30 increases. When the lead screw 2201 drives the drive block 2202 to move to the right, the slider 2107 moves to the right accordingly, the scissor lift 2103 opens, the angle between the first scissor lift 2104 and the second scissor lift 2105 increases, the telescopic part 210 shortens, and the distance between the first fastener part 10 and the second fastener part 30 decreases.

[0073] It should be noted that the slide rail 2106, guide rail, and lead screw 2201 are all parallel to the third direction.

[0074] It should also be noted that the lead screw 2201 is rotatably mounted on the second telescopic support plate 2102 via rolling bearings; in addition, a handwheel is provided on the lead screw 2201, the handwheel is located at the end of the support base 2303 away from the transmission plate 2306, and there is a gap between the handwheel and the locking part 230; by rotating the handwheel, the lead screw 2201 can be driven to rotate.

[0075] like Figures 3-5As shown, in some embodiments, the adjusting assembly 20 further includes a locking part 230, which includes a fixed seat 2301, a support ring 2302, a support seat 2303, a plurality of locking elements 2305, and a transmission disc 2306; the fixed seat 2301 is disposed on the second telescopic support plate; the support ring 2302 is disposed at one end of the fixed seat 2301 near the lead screw 2201; the support seat 2303 is disposed on the inner wall of the support ring 2302, and the support seat 2303 is provided with a plurality of through slots 2304, one end of the plurality of through slots 2304 being connected and arranged at equal intervals around the support seat 2303 in the circumferential direction, and the through slots 2304 being in the axial direction of the support seat 2303. The upper through support base 2303; multiple locking elements 2305 correspond one-to-one with multiple through slots 2304, and the locking elements 2305 are movably disposed in the corresponding through slots 2304; the transmission disk 2306 is rotatably disposed on one end of the fixed base 2301 near the lead screw 2201, the transmission disk 2306 is located in the support ring 2302 and connected to the locking elements 2305; wherein, the lead screw 2201 is coaxially disposed with the support base 2303 and passes through the support base 2303, and the transmission disk 2306 is configured to drive the multiple locking elements 2305 to move along the radial direction of the support base 2303, so that the multiple locking elements 2305 clamp or release the lead screw 2201.

[0076] like Figure 4 , Figure 5 As shown, in some embodiments, the transmission disk 2306 is provided with a plurality of transmission grooves 2307, which are arranged at equal intervals around the circumference of the transmission disk 2306, and each of the plurality of transmission grooves 2307 corresponds to a plurality of locking members 2305; wherein, the transmission grooves 2307 are arc-shaped, and the locking members 2305 are slidably connected to the corresponding transmission grooves 2307.

[0077] The support base 2303 and the support ring 2302 provide a structural foundation for the installation of the support base 2303 and the transmission disc 2306. Since the locking member 2305 is slidably connected to the transmission groove 2307 on the transmission disc 2306, and the locking member 2305 is movably disposed within the corresponding through groove 2304, rotating the transmission disc 2306 causes the locking member 2305 to move along the through groove 2304, thereby moving the locking member 2305 radially. This allows the locking member 2305 to move closer to or further away from the lead screw 2201, thus clamping or releasing the lead screw 2201.

[0078] It should be noted that the number of through slots 2304, locking elements 2305, and transmission slots 2307 are equal, and the specific number can be set according to specific needs; for example, such as Figure 4 , Figure 5 As shown, there are four through slots 2304, four locking parts 2305, and four transmission slots 2307.

[0079] It should also be noted that the support ring 2302, support base 2303, and transmission disc 2306 are all coaxially arranged with the lead screw 2201; multiple through slots 2304 are connected, and the connection point is located at the center of the support base 2303, thus providing a channel for the lead screw 2201 to pass through.

[0080] It should also be noted that first limiting grooves are respectively provided on both sides of the through groove 2304, and limiting blocks are respectively provided on both sides of the locking member 2305. The limiting blocks are matched with the shape of the first limiting grooves, so that the locking member 2305 is movably set in the through groove 2304. The locking member 2305 is also provided with a locking rod 2308, which extends into the corresponding transmission groove 2307. The locking rod 2308 is provided with an annular block, and second limiting grooves are respectively provided on both sides of the transmission groove 2307. The annular block is matched with the second limiting grooves, so that the locking rod 2308 is movably set in the transmission groove 2307, realizing the sliding connection between the locking block and the transmission groove 2307. Thus, when the transmission disc 2306 rotates, it drives the locking rod 2308 to slide along the transmission groove 2307, causing the locking block to move along the through groove 2304.

[0081] It should also be noted that, such as Figure 4 , Figure 5 As shown, the locking part 230 also includes a rotating rod 2310 and a locking screw. One end of the rotating rod 2310 is connected to the transmission disk 2306 and the other end is provided with a first threaded hole. The fixed base 2301 is provided with a second threaded hole 2311 and a third threaded hole 2312. The second threaded hole 2311 and the third threaded hole 2312 are arranged circumferentially around the transmission disk 2306. Rotating the rotating rod 2310 drives the transmission disc 2306 to rotate. When the locking part 230 clamps the lead screw 2201, the transmission disc 2306 rotates until the first threaded hole and the second threaded hole 2311 are coaxial. The locking screw is threaded into the first threaded hole and the second threaded hole 2311, fixing the transmission disc 2306 onto the fixed base 2301. This prevents the transmission disc 2306 from rotating erroneously and ensures that the lead screw 2201 is in a fixed state and no longer rotates, so that the distance between the first fastener part 10 and the second fastener part 30 remains unchanged. When the locking part 230 releases the lead screw 2201, the transmission disc 2306 rotates until the first threaded hole and the third threaded hole 2312 are coaxial. The locking screw is threaded into the first threaded hole and the third threaded hole 2312, fixing the transmission disc 2306 onto the fixed base 2301, thus preventing the transmission disc 2306 from rotating erroneously.

[0082] It should also be noted that two locking parts 230 can be provided, which are located at both ends of the lead screw 2201, thereby improving the clamping effect on the lead screw 2201 and effectively preventing the lead screw 2201 from rotating.

[0083] In some embodiments, the locking member 2305 is provided with a locking notch 2309 at one end near the lead screw 2201. The locking notch 2309 is arc-shaped and matches the shape of the lead screw 2201.

[0084] By setting an arc-shaped locking notch 2309 that can match the shape of the lead screw 2201, the clamping effect of the locking component 2305 is further guaranteed.

[0085] It should be noted that, as Figure 4 As shown, when the transmission disc 2306 drives the four locking parts 2305 to clamp the lead screw 2201, the locking notches 2309 of the four locking parts 2305 are spliced ​​into a circle.

[0086] like Figure 1 As shown, in some embodiments, both the first fastener part 10 and the second fastener part 30 include a rotating base 1101 and a pressure cover 1102; the rotating base 1101 is rotatably connected to the adjusting assembly 20; one end of the pressure cover 1102 is hinged to the rotating base 1101, and the other end is provided with a fastener 1105 to connect the rotating base 1101 and the pressure cover 1102; wherein, the top of the rotating base 1101 is provided with a first fastening groove 1103, and the bottom of the pressure cover 1102 is provided with a second fastening groove 1104 that cooperates with the first fastening groove 1103 to form a fixing groove for fixing the scaffold.

[0087] It should be noted that the rotating base 1101 of the first fastener part 10 is rotatably connected to the first telescopic support plate 2101 via a rolling bearing, and the rotating base 1101 of the second fastener part 30 is rotatably connected to the second telescopic support plate 2102 via a tumbling bearing.

[0088] It should also be noted that the pressure cap 1102 is provided with a fourth threaded hole, and the rotating base 1101 is provided with a fifth threaded hole; the fastener 1105 is a screw, and the fastener 1105 is threadedly connected to the fourth threaded hole and the fifth threaded hole respectively, thereby fixing the rotating base 1101 to the pressure cap 1102.
