Description

Technical Field

[0001] This utility model relates to the field of scaffolding connection, and in particular to a connection device for quick assembly of scaffolding. Background Technology

[0002] Scaffolding is a temporary structure widely used in construction, equipment installation, stage construction and other projects. It consists of uprights, horizontal bars, diagonal bars and other pipes connected by various devices. Its main function is to provide a working platform for construction workers to facilitate their work at heights. It is an indispensable and important auxiliary facility in modern engineering construction. The installation speed of the connecting devices often directly determines the speed of scaffolding erection.

[0003] Existing scaffolding connection devices have significant shortcomings in practical applications. The installation process may require the use of multiple tools, and the structural design of traditional connection devices is relatively complex, with cumbersome operation steps, which greatly affects construction efficiency. In addition, existing connection devices cannot adjust the angle of the horizontal bars, which is very limiting when facing complex construction environments and diverse construction needs. The inability to flexibly adjust the angle of the horizontal bars restricts the adaptability of scaffolding and cannot meet the special needs of different engineering scenarios.

[0004] Therefore, in view of the problems of slow installation speed and insufficient adaptability of existing scaffolding connection devices, which cannot adjust the angle of the crossbars, a quick-assembly connection device for scaffolding can be designed to simplify the cumbersome operation steps, improve the installation speed, and improve the adaptability of scaffolding by adjusting the angle of the crossbars when facing complex construction environments and diverse construction needs. Utility Model Content

[0005] To overcome the problems of slow installation speed and insufficient adaptability of existing scaffolding connection devices, which cannot adjust the angle of the crossbars.

[0006] The technical solution of this utility model is as follows: a connecting device for quick assembly of scaffolding, including a base, connecting rods installed on the upper and lower sides of the base, a rotating block rotatably connected to the outer side of the connecting rod, a top block installed at the right end of the rotating block, limit plates installed at both the upper and lower ends of the connecting rod, fixing holes opened on the surface of the limit plates, a connecting box fixedly connected to the upper end of the limit plate, a support rod slidably connected to the inner side of the connecting box, a first limit block installed inside the fixing hole, a first fixing block provided on the side of the first limit block, a sleeve fixedly connected to the right end of the first fixing block, and a second fixing block installed at the upper end of the sleeve.

[0007] Preferably, a rotating rod is fixedly connected to the left end of the rotating block, the fixing holes are distributed in a ring array, and the fixing holes are designed in a gourd shape.

[0008] Preferably, the lower end of the fixed block is equipped with sliding limit blocks on both the front and rear sides of the limiting block. The sliding limit blocks are I-shaped, and both the limiting block and the sliding limit blocks are slidably connected to the fixing hole.

[0009] Preferably, the lower end of the fixed block is provided with a sliding groove, and the sliding groove and the sliding limit block are slidably connected.

[0010] Preferably, the lower end of the fixing block 2 is fixedly connected to the insertion rod 1, and the upper end face of the sleeve is provided with the insertion hole 1, and the insertion hole 1 and the insertion rod 1 are slidably connected.

[0011] Preferably, there are two connection boxes. The connection box has a second socket, which is formed by passing through the connection box from front to back. A second plug rod is slidably connected to the inner side of the second socket, and a third fixing block is fixedly connected to the rear end of the second plug rod.

[0012] Preferably, a fixing box is installed at the rear end of the connecting box outside the fixing block three. The fixing box and the fixing block three are sleeved together. A locking groove is opened on the upper end face of the fixing box, and a locking insert is slidably connected to the inner side of the locking groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. The quick-assembly connection device for this scaffolding allows for adjustment of the fixed block 1 according to the required angle during construction. After determining the angle, the lower limit block 1 and the sliding limit block are inserted into the large hole of the lower fixing hole. The fixed block 1 is pulled outward to allow the limit block 1 and the sliding limit block to slide into the small hole of the fixing hole and engage with each other. By rotating the rotating rod, the top block is rotated to the side of the limit block 1 and the sliding limit block to fix them and prevent them from falling off. This facilitates the adjustment of the horizontal bar angle and improves the adaptability of the scaffolding surface to complex construction environments.

[0015] 2. The connecting device for quick scaffolding assembly first inserts the support rod vertically into the connecting box, then inserts the second insertion rod into the second insertion hole to fix the support rod, and finally inserts the locking plate to fix the fixing block three at the rear end of the second insertion rod to prevent the second insertion rod from falling off. While ensuring the structural stability, it simplifies the cumbersome operation steps and realizes quick scaffolding assembly. Attached Figure Description

After determining the angle, insert the limiting block 10 and sliding limiting block 101 at the lower end of the fixing block 6 into the fixing hole 21 below. Pull the fixing block 6 outward. By rotating the rotating rod 31, rotate the top block 32 to the side of the limiting block 10 and sliding limiting block 101 to fix them and prevent them from falling off. First, insert the support rod 9 into the connecting box 4 in the vertical direction. Then, insert the second insertion rod 5 into the insertion hole 41 to fix the support rod 9. Finally, insert the locking plate 112 to fix the fixing block 3 51 at the rear end of the second insertion rod 5 to prevent the second insertion rod 5 from falling off. This simplifies the complicated operation steps and improves the installation speed while ensuring the structural firmness.

[0024] Please refer to 1. Figure 2 , Figure 4 and Figure 5In this embodiment, a rotating rod 31 is fixedly connected to the left end of the rotating block 3. The fixing holes 21 are arranged in a circular array and have a gourd-shaped structure. Sliding limiting blocks 101 are installed on both the front and rear sides of the limiting block 10 at the lower end of the fixing block 6. The sliding limiting blocks 101 have an I-shaped structure. Both the limiting block 10 and the sliding limiting blocks 101 are slidably connected to the fixing holes 21. A sliding groove 62 is provided at the lower end of the fixing block 6, and the sliding groove 62 is slidably connected to the sliding limiting block 101. The angle is adjusted according to the construction requirements. After adjusting the fixed block 6 and determining the angle, insert the lower limit block 10 and sliding limit block 101 of the fixed block 6 into the large hole of the lower fixed hole 21. Pull the fixed block 6 outward so that the limit block 10 and sliding limit block 101 slide into the small hole of the fixed hole 21 and engage with each other. By rotating the rotating rod 31, rotate the top block 32 to the side of the limit block 10 and sliding limit block 101 to fix them and prevent them from falling off. This is beneficial for adjusting the angle of the crossbar and improves the adaptability of the scaffold surface to complex construction environments.

[0025] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a first insertion rod 81 is fixedly connected to the lower end of the second fixing block 8, and a first insertion hole 63 is opened on the upper end face of the sleeve 61. The first insertion hole 63 and the first insertion rod 81 are slidably connected. Two connecting boxes 4 are provided, and a second insertion hole 41 is opened on the connecting box 4. The second insertion hole 41 is formed by passing through the connecting box 4 from front to back. A second insertion rod 5 is slidably connected to the inner side of the second insertion hole 41. A third fixing block 51 is fixedly connected to the rear end of the second insertion rod 5. A fixing box 11 is installed on the rear end of the connecting box 4 outside the third fixing block 51. The fixed box 11 and the fixing block 3 51 are sleeved together. The upper end face of the fixed box 11 has a locking groove 111. The locking plate 112 is slidably connected to the inner side of the locking groove 111. First, the support rod 9 is inserted vertically into the connecting box 4. Then, the second rod 5 is inserted into the second hole 41 to fix the support rod 9. Finally, the locking plate 112 is inserted to fix the fixing block 3 51 at the rear end of the second rod 5, preventing the second rod 5 from falling off. While ensuring the structural firmness, the complicated operation steps are simplified, and the installation speed is effectively improved.

[0026] During operation, the fixing block 6 is adjusted according to the required angle. After determining the angle, the limiting block 10 and sliding limiting block 101 at the lower end of the fixing block 6 are inserted into the large hole of the fixing hole 21 below. The fixing block 6 is pulled outward to make the limiting block 10 and sliding limiting block 101 slide into the small hole of the fixing hole 21 and engage with each other. By rotating the rotating rod 31, the top block 32 is rotated to the side of the limiting block 10 and sliding limiting block 101 to fix them and prevent them from falling off. This facilitates the adjustment of the crossbar angle and improves efficiency. To enhance the adaptability of the scaffolding to complex construction environments, the horizontal bar is inserted into the sleeve 61, and then the first insert rod 81 is inserted into the first insertion hole 63 to fix the horizontal bar and the sleeve 61. First, the vertical direction is fixed by inserting the support rod 9 into the connecting box 4, and then the second insert rod 5 is inserted into the second insertion hole 41 to fix the support rod 9. Finally, the locking plate 112 is inserted to fix the fixing block 3 51 at the rear end of the second insert rod 5 to prevent the second insert rod 5 from falling off. While ensuring the structural stability, the complicated operation steps are simplified, and the scaffolding can be quickly assembled.

[0027] Through the above steps, during construction, the fixing block 6 can be adjusted according to the required angle. After determining the angle, the limiting block 10 and the sliding limiting block 101 are inserted into the large hole of the fixing hole 21, and then pulled outward to slide into the small hole and engage. The rotating rod 31 is rotated to make the top block 32 rotate to the side and fix it to prevent it from falling off. This can adjust the angle of the horizontal bar and improve the adaptability of the scaffolding to complex construction environments, so as to solve the problem that the existing scaffolding connection device has a slow installation speed and insufficient adaptability to adjust the angle of the horizontal bar.
