[0002] The plug-in type disc-lock scaffolding consists of uprights, horizontal bars, diagonal bars, adjustable bases, and adjustable supports, among other accessories. It uses high-strength steel pipes and connectors, and achieves rapid assembly and disassembly through the plug-in type disc-lock connection method. The horizontal bars of the plug-in type disc-lock scaffolding are its core components, mainly used to connect the uprights and form a stable support structure.
[0003] The horizontal bars are welded to both ends with snap-fit joints, which are then fixed with wedge-shaped pins by inserting them into the connecting plates on the vertical bars, forming a robust joint. These joints not only have strong torsional resistance but also possess high strength, rigidity, and stability, ensuring the safety of the scaffolding under various construction conditions.
[0004] In the existing technology, the fixed-length horizontal bars limit the adaptability of scaffolding under different working conditions and cannot be adjusted according to the specific needs of the construction site. In order to adapt to different construction environments, it is necessary to purchase horizontal bars of various specifications, which increases the cost of procurement and management. Fixed-length horizontal bars require more space for storage and are not easy to stack, occupying warehouse resources. Therefore, a telescopic horizontal bar for scaffolding that is easy to install is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an easy-to-install telescopic horizontal bar for scaffolding, aiming to improve the problem that fixed-length horizontal bars in the prior art limit the adaptability of scaffolding and increase procurement and management costs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A retractable horizontal bar for easy installation of scaffolding includes a crossbar, an extension bar slidably connected to the inner wall of the crossbar, a fixing ring fixedly connected to the outer side of the crossbar, a rotating block rotatably connected to the inner wall of the fixing ring, a locking block rotatably connected to the inner wall of the fixing ring, the other end of the rotating block contacting the outer side of the locking block, a locking groove is formed on the outer side of the extension bar, the outer side of the locking block contacts the outer side of the locking groove, and a connecting component is fixedly connected to the outer side of the crossbar to allow the horizontal bar to be connected to other structures.
[0008] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:
[0013] The inner wall of the fixed box is fixedly connected with multiple springs, and the other end of each spring is fixedly connected to the outside of the sliding block.
[0014] As a further description of the above technical solution:
[0015] The inner walls of the two sliding blocks are slidably connected by pins, and the inner walls of the pins are provided with four sliding grooves.
[0016] As a further description of the above technical solution:
[0017] The inner wall of the sliding groove is fixedly connected to multiple springs, and the other end of each spring is fixedly connected to a sliding column.
[0018] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the movement of the other end of the rotating block can push the locking block closer to the outside of the locking groove of the extension rod, so that the locking block and the locking groove are in close contact, thereby determining the positional relationship between the horizontal bar and the extension rod, and thus determining the length of the entire horizontal bar. The variable length design significantly improves the adaptability and flexibility of the scaffolding, enabling it to easily meet the construction needs of different heights and widths, without the need to frequently replace or carry horizontal bars of various specifications, simplifying the installation process.
[0024] 2. In this utility model, after the external force is removed, the reset of multiple springs one pulls the sliding block to move in the direction of tightening the pin, and the reset of multiple springs two causes the sliding column to slide through the sliding groove, thereby engaging with the inner wall of the moving opening.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a retractable horizontal scaffolding member that is easy to install. It includes a horizontal bar 1, with an extension rod 2 slidably connected to the inner wall of the horizontal bar 1. The extension rod 2 and the horizontal bar 1 work together to extend the length of the horizontal bar. A limiting ring 7 is fixedly connected to the outside of the extension rod 2, and the limiting ring 7 is slidably connected to the inside of the horizontal bar 1. The limiting ring 7 is used to prevent the extension rod 2 from detaching from the inside of the horizontal bar 1 during movement. A fixing ring 3 is fixedly connected to the outside of the horizontal bar 1, and the fixing ring 3 protects the internal locking structure.
[0034] A rotating block 6 is rotatably connected to the inner wall of the fixed ring 3, and a locking block 5 is rotatably connected to the inner wall of the fixed ring 3. The other end of the rotating block 6 is in contact with the outside of the locking block 5 (as shown in the attached figure). Figure 4 The rotating block 6 is turned, and the other end of the rotating block 6 can press the locking block 5, so that the other end of the locking block 5 can change position. The extension rod 2 has a locking groove 4 on its outside. The outside of the locking block 5 is in contact with the outside of the locking groove 4. When the locking block 5 moves, it can be close to the outside of the locking groove 4, thereby fixing the position of the crossbar 1 and the extension rod 2.
[0035] Reference Figure 3 and Figure 5 The horizontal bar 1 is externally fixedly connected to a connecting assembly that allows the horizontal bar to connect with other structures. This connecting assembly includes two fixing blocks 8, each externally fixedly connected to two fixing boxes 9. The fixing blocks 8 provide support and fixation for the two fixing boxes 9. A sliding block 12 is slidably connected to the inner wall of each fixing box 9, and a push block 10 is externally fixedly connected to the sliding block 12. Changing the position of the push block 10 allows the sliding block 12 to move accordingly. The external fixing blocks 8 are fixedly connected to the outside of the horizontal bar 1, and the other fixing block 8 is externally fixedly connected to the outside of the extension bar 2, ensuring that both ends of the horizontal bar can be connected to the outside.
[0036] Multiple springs 11 are fixedly connected to the inner wall of the fixing box 9, and the inner wall of the fixing box 9 fixes one end of the multiple springs 11. The other end of the multiple springs 11 is fixedly connected to the outside of the sliding block 12. The position change of the sliding block 12 causes the multiple springs 11 to deform. The return of the multiple springs 11 causes the position of the sliding block 12 to move, thereby locking the fixing structure. The inner walls of two sliding blocks 12 are slidably connected with pins 13. The pins 13 move along the inner walls of the sliding blocks 12, thereby enabling the connection and fastening with other structures.
[0037] The inner wall of the pin 13 has four sliding grooves 16, and multiple springs 14 are fixedly connected to the inner wall of the sliding grooves 16. The sliding grooves 16 fix one end of each spring 14. The other end of each spring 14 is fixedly connected to a sliding post 15 (as shown in the attached figure). Figure 5The movement of the sliding post 15 causes multiple springs 14 to deform, and the reset of the multiple springs 14 can push the sliding post 15 to reset. The fixed box 9 has two moving ports 17 inside. The outside of the sliding post 15 is slidably connected to the inner wall of the moving port 17. When the sliding post 15 slides to the inner wall of the moving port 17, it can be engaged.
[0038] Working principle: First, pull the extension rod 2 to change its sliding position on the inner wall of the crossbar 1. Then, move the rotating block 6. The other end of the rotating block 6 moves and pushes the locking block 5 closer to the outside of the locking groove 4 of the extension rod 2, so that the locking block 5 is in close contact with the locking groove 4. This determines the positional relationship between the crossbar 1 and the extension rod 2, thereby determining the length of the entire horizontal bar. The variable length design significantly improves the adaptability and flexibility of the scaffolding, making it easy to meet the construction needs of different heights and widths. It eliminates the need for frequent replacement or carrying of horizontal bars of various specifications, simplifies the installation process, and facilitates storage and transportation because the same number of adjustable horizontal bars occupy less space and are easy to stack and transport.
[0039] Pressing and holding the actuating block 10 moves the sliding block 12, causing it to move. This movement of the sliding block 12 causes multiple springs 11 to deform. Pressing and holding the sliding posts 15 causes them to move closer to the pin 13, deforming multiple springs 14. Sliding the pin 13 allows its outer surface to pass through the fixing box 9 and engage with the inner wall of the sliding block 12. After the external force is removed, the springs 11 return to their original position, pulling the sliding block 12 towards the direction of tightening the pin 13. The return of the springs 14 causes the sliding posts 15 to slide through the sliding groove 16, thus engaging with the inner wall of the moving opening 17. Adding a locking structure to the connection between the horizontal bar and other bars significantly improves the stability and safety of the scaffold. By ensuring a tight connection between the bars, the locking structure effectively prevents the risk of scaffold collapse due to loosening or displacement, providing a safer working environment for construction workers.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
