Description

Technical Field

[0001] The utility model relates to a joint, in particular to a quick disassembly and assembly scaffolding joint applied in the scaffolding field. Background Art

[0002] Scaffolding refers to various supports set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is mainly for construction workers to work up and down or for external safety net protection and high-altitude installation of components. To put it simply, it is a frame. Scaffolding is a common auxiliary tool in engineering construction. The connection of each steel pipe in the scaffolding is completed by using joints.

[0003] The specification of Chinese patent CN207131066U discloses a quick connector for steel pipe scaffolding, which first pre-assembles the connector with bolts, nuts, and tube washers, butts the steel pipes together, and then tightens the bolts with an electric tool. The disassembly is done in the reverse order. It has the advantages of reasonable structure and convenient and quick disassembly and assembly.

[0004] However, when making connections, the bolts are disassembled and assembled slowly and inefficiently. After being fixed for a long time, the bolts may rust due to long-term contact with moisture in the air. Not only are they inconvenient to disassemble, they are also prone to breakage, which can easily lead to safety accidents over time. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that scaffold joints are usually installed and fixed with bolts, but the bolts are not only slow to disassemble and assemble and have low efficiency, but also rust with moisture in the air, making the scaffold easy to break during use.

[0006] To solve the above problems, the utility model provides a quick disassembly and assembly scaffolding joint, including a positioning tube, the longitudinal section of the positioning tube is I-shaped, the I-shape divides the interior of the positioning tube into an upper inner cavity and a lower inner cavity, the upper and lower side walls of the positioning tube are provided with a plurality of tooth grooves, the upper and lower inner walls of the positioning tube are fixedly connected with fixing columns, the upper and lower inner cavities of the positioning tube are both inserted with scaffolding tubes one, the outer ring of the scaffolding tube one is fixedly connected with a plurality of tooth blocks, the tooth blocks match the tooth grooves, the upper and lower inner cavities of the positioning tube are also respectively inserted with positioning plates, the inner wall of the positioning tube is provided with two accommodating holes, the two accommodating holes respectively correspond to the ends of the two positioning plates located in the positioning tube, the vertical inner wall of the accommodating hole is fixedly connected with a spring, the end of the spring close to the positioning plate is fixedly connected with a protrusion, and the front end of the protrusion passes through the positioning plate.

[0007] In the above-mentioned quick disassembly and assembly scaffolding joint, no bolts are needed for fixing, and disassembly and assembly are convenient and efficient.

[0008] As a further improvement of the present application, the longitudinal section of the positioning plate is inverted L-shaped, and the upper end of the positioning plate is fan-shaped and the lower end is an arc-shaped column. The positioning plate is simultaneously fitted with the scaffolding tube and the positioning tube.

[0009] As a further improvement of the present application, the fixing column is located inside the scaffolding tube one, and the diameter of the fixing column is the same as the inner diameter of the scaffolding tube one.

[0010] As a further improvement of the present application, the tooth grooves and the tooth blocks are both trapezoidal, the distribution range of the multiple tooth grooves in the radial direction of the positioning tube does not exceed 180°, the positioning plate does not overlap with the multiple tooth grooves, and the positioning plate is opposite to the multiple tooth grooves.

[0011] As another improvement of the present application, the projection is hemispherical, and the front end of the projection is in contact with the outer surface of the scaffolding tube 1.

[0012] As another improvement of the present application, a mounting tube is fixedly sleeved at the center of the outer surface of the positioning tube, a plurality of inserting tubes are fixedly connected to the outer surface of the mounting tube, a scaffolding tube 2 is inserted in the inserting tube, a fixing plate is provided at the upper end of the inserting tube, and the lower end of the fixing plate passes through the inserting tube and the scaffolding tube 2 in sequence.

[0014] To sum up, in actual application, the scaffolding tube 1 is inserted into the positioning tube so that the fixing column is located in the scaffolding tube 1 and the tooth block is located in the tooth groove, thereby limiting the scaffolding tube 1, and then the positioning plate is inserted into the positioning tube. The protrusion is squeezed and moves into the accommodating hole until the bottom of the positioning plate and the scaffolding tube 1 are in the same plane. The protrusion is reset and penetrates the positioning plate, thereby fixing the positioning plate, making the positioning plate and scaffolding tube 1 fit each other, thereby performing secondary limiting and fixing of the scaffolding tube 1, and then completing the installation of the scaffolding tube 1. No bolts are required for fixing, which improves the disassembly and assembly efficiency and facilitates the use of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0027] The first implementation method:

[0028] Figure 1 and Figure 2 Shown is a quick disassembly scaffolding joint, comprising a positioning tube 1, wherein the upper inner cavity and the lower inner cavity of the positioning tube 1 are both inserted with a scaffolding tube 4, and the outer ring of the scaffolding tube 4 is fixedly connected with a plurality of tooth blocks 5.

[0029] Figure 3 It is shown that the longitudinal section of the positioning tube 1 is in an I-shaped shape, which divides the interior of the positioning tube 1 into an upper inner cavity and a lower inner cavity. The upper and lower side walls of the positioning tube 1 are both provided with a plurality of tooth grooves 2. The upper and lower inner walls of the positioning tube 1 are both fixedly connected with fixing columns 3, which are located in the scaffolding tube 1 4, and the diameter of the fixing columns 3 is the same as the inner diameter of the scaffolding tube 1 4. The upper and lower inner cavities of the positioning tube 1 are also respectively inserted with positioning plates 6, and the positioning plates 6 are improved by the mutual fit and extrusion between the positioning plates 6 and the scaffolding tube 1 4. The friction between the scaffolding tube 4 and the positioning tube 1 makes it difficult for the scaffolding tube 4 to slide out. The inner wall of the positioning tube 1 is provided with two accommodating holes 7, which respectively correspond to the ends of the two positioning plates 6 located in the positioning tube 1. A spring 8 is fixedly connected to the vertical inner wall of the accommodating hole 7, and the spring 8 facilitates the forward and backward movement of the protrusion 9. The end of the spring 8 close to the positioning plate 6 is fixedly connected to the protrusion 9, and the positioning plate 6 can be fixed by the protrusion 9. The front end of the protrusion 9 passes through the positioning plate 6.

[0030] Figure 4 and Figure 5 It is shown that the tooth groove 2 and the tooth block 5 are both trapezoidal, and the tooth block 5 matches the tooth groove 2. Through the coordinated use of the tooth block 5 and the tooth groove 2, the scaffolding tube 4 can be prevented from rotating after installation, thereby improving the stability of the scaffolding tube 4. The radial distribution range of the multiple tooth grooves 2 in the positioning tube 1 does not exceed 180°, the positioning plate 6 does not overlap with the multiple tooth grooves 2, and the positioning plate 6 is opposite to the multiple tooth grooves 2.

[0031] Figure 6 It is shown that the longitudinal section of the positioning plate 6 is inverted L-shaped, which makes it easy for the staff to disassemble and assemble the positioning plate 6, and the upper end of the positioning plate 6 is fan-shaped and the lower end is an arc-shaped column. The positioning plate 6 is in contact with the scaffolding pipe 4 and the positioning pipe 1 at the same time.

[0032] Figure 7 It is shown that the protrusion 9 is hemispherical, and the hemispherical shape facilitates the protrusion 9 to move into the accommodating hole 7 under force, and the front end of the protrusion 9 contacts the outer surface of the scaffolding tube 4.

[0033] Insert the scaffolding tube 4 into the positioning tube 1 so that the fixing column 3 is located in the scaffolding tube 4 and the tooth block 5 is located in the tooth groove 2, thereby limiting the scaffolding tube 4, and then insert the positioning plate 6 into the positioning tube 1, and the protrusion 9 is squeezed and moves into the accommodating hole 7 until the bottom of the positioning plate 6 and the scaffolding tube 4 are in the same plane, the protrusion 9 is reset and penetrates the positioning plate 6, thereby fixing the positioning plate 6, making the positioning plate 6 and the scaffolding tube 4 fit each other, thereby performing secondary limiting and fixing on the scaffolding tube 4, and then completing the installation of the scaffolding tube 4. When disassembling, it is only necessary to take out the positioning plate 6 and the scaffolding tube 4 respectively.

[0034] The second implementation method:

[0035] On the basis of the first embodiment, this embodiment adds a mounting pipe 10, an inserting pipe 11, a second scaffolding pipe 12 and a fixing plate 13, and the rest of the parts remain the same as the first embodiment.

[0036] Figure 8 and Fig. 9 It is shown that: a mounting tube 10 is fixedly sleeved at the center of the outer surface of the positioning tube 1, a plurality of inserting tubes 11 are fixedly connected to the outer surface of the mounting tube 10, a scaffolding tube 12 is inserted in the inserting tube 11, a fixing plate 13 is provided at the upper end of the inserting tube 11, the scaffolding tube 12 and the inserting tube 11 can be fixed by the fixing plate 13, and the lower end of the fixing plate 13 passes through the inserting tube 11 and the scaffolding tube 12 in sequence, the inner diameter of the inserting tube 11 is the same as the diameter of the scaffolding tube 12, the fixing plate 13 is T-shaped, and the upper and lower connecting parts of the fixing plate 13 are arc-shaped, and the upper and lower connecting surfaces of the fixing plate 13 are in contact with the outer surface of the inserting tube 11.

[0037] When installing the horizontal scaffolding pipe 12, it is only necessary to insert the scaffolding pipe 12 into the inserting pipe 11, and then fix the scaffolding pipe 12 and the inserting pipe 11 by inserting the fixing plate 13. The operation is simple and convenient, and the work efficiency is improved.

[0038] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
