Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable length disc buckle crossbar. Background Technology

[0002] Disc-lock crossbars provide support for scaffold boards, transferring the load from the boards to the uprights and ensuring the safety of workers on the scaffold boards. They are typically made of high-strength steel, with standardized dimensions for easy installation, disassembly, and transportation. In practical applications, disc-lock crossbar devices usually require the following technologies:

[0003] 1. Connecting mechanism: The small crossbar is connected to the connecting plate on the upright through a pin;

[0004] 2. Support mechanism to ensure a secure connection between the joint and the small crossbar;

[0005] 3. The horizontal adjustment mechanism allows for fine-tuning of the horizontal level of the small crossbar;

[0006] The small horizontal bar connects adjacent vertical poles together to form an integrated scaffolding structure. The small horizontal bar is connected to the connecting plate on the vertical pole through a pin, so that the vertical poles can transfer force to each other. Together with the vertical poles, diagonal poles, etc., it forms a stable triangular structure, which improves the overall rigidity and stability of the scaffolding.

[0007] The horizontal bars are usually made of high-strength steel and are mostly one-piece stamped designs, which means that the horizontal bars are fixed length members. However, in use, the distance between the two uprights of the scaffold will change, and it is necessary to take the corresponding length of horizontal bar for installation and fixation, which reduces the scaffold assembly speed. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this utility model provides an adjustable-length disc-lock crossbar, solving the technical problem that most crossbars are one-piece stamped designs, resulting in fixed-length crossbars. However, during use, the distance between the two uprights of the scaffold may change, requiring the use of crossbars of corresponding length for installation and fixation, thus reducing the speed of scaffold assembly.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] An adjustable length disc buckle crossbar includes a first crossbar, a second crossbar slidably mounted on the side end of the first crossbar, at least two positioning holes being provided inside the second crossbar, a pin block slidably mounted on the bottom end of the first crossbar, and spring buttons slidably mounted on both side ends of the pin block.

[0013] Preferably: a rotating rod is rotatably mounted on the bottom end of the pin block, two buffer plates are fixedly mounted on both sides of the pin block, a drive shaft is rotatably mounted on both sides of the pin block, a support sleeve is rotatably mounted on the surface of each drive shaft, a return spring is mounted on the side end of each of the spring buttons, a socket is opened at the bottom end of the first crossbar, and the top end of the pin block is aligned with the socket.

[0014] (III) Beneficial Effects

[0015] 1. By rotating the two drive shafts, the drive shafts rotate at the side end of the pin block, which simultaneously drives the support sleeve to move inward into the pin block, allowing the support sleeve to leave the inside of the positioning hole. By pulling the pin block, the pin block slides at the bottom end of the first horizontal bar, and the pin block leaves the inside of the positioning hole. By pulling the second horizontal bar, the second horizontal bar slides at the side end of the first horizontal bar. The length can be adjusted through the hole of the pin, and the length can be freely adjusted according to the spacing of the scaffold uprights.

[0016] 2. By moving the pin block, insert the pin block into the bottom end of the first crossbar. At the same time, the top end of the pin block inserts into the positioning hole. The bottom end of the first crossbar presses the spring button block. A return spring is installed on the side end of the spring button block. Under the force of the return spring, the spring button block slides into the end of the first crossbar. At the same time, a buffer plate is installed on the side end of the pin block. The buffer plate can increase the friction between the pin block and the positioning hole, which facilitates quick docking and prevents shaking. Attached Figure Description

[0023] This application provides an adjustable-length disc-lock crossbar, effectively solving the problem that most crossbars are one-piece stamped designs, resulting in fixed-length crossbars. However, during use, the distance between the two uprights of the scaffold changes, requiring the use of crossbars of corresponding length for installation and fixing, thus reducing the scaffold assembly speed. By rotating two drive shafts, the drive shafts rotate at the side end of the pin block, simultaneously driving the support sleeve to move inward from the pin block, allowing the support sleeve to leave the positioning hole. By pulling the pin block, the pin block slides at the bottom end of the first crossbar, leaving the pin block inside the positioning hole. By pulling the second crossbar, the second crossbar slides at the side end of the first crossbar. The length can be adjusted freely according to the distance between the uprights of the scaffold by using the holes in the pins.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that the horizontal bars are mostly one-piece stamped designs, resulting in fixed-length bars. However, during use, the distance between the two uprights of the scaffolding will change, requiring the use of horizontal bars of corresponding length for installation and fixation, which reduces the assembly speed of the scaffolding. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides an adjustable length disc buckle crossbar, including a first crossbar 11, a second crossbar 12 slidably mounted on the side end of the first crossbar 11, at least two positioning holes 13 inside the second crossbar 12, a pin block 14 slidably mounted on the bottom end of the first crossbar 11, and spring buttons 16 slidably mounted on both side ends of the pin block 14. The bottom end of the first crossbar 11 presses against the spring buttons 16, and a return spring is installed on the side end of the spring buttons 16. Under the force of the return spring, the spring buttons 16 slide into the end of the first crossbar 11.

[0027] A rotating rod 15 is rotatably mounted on the bottom end of the pin block 14. Two buffer plates 17 are fixedly mounted on both sides of the pin block 14. A drive shaft 18 is rotatably mounted on both sides of the pin block 14. A support sleeve 19 is rotatably mounted on the surface of each drive shaft 18. By rotating the two drive shafts 18, the drive shafts 18 rotate on the sides of the pin block 14, and at the same time drive the support sleeve 19 to move into the interior of the pin block 14, so that the support sleeve 19 leaves the interior of the positioning hole 13. By pulling the pin block 14, the pin block 14 slides at the bottom end of the first crossbar 11 and leaves the interior of the positioning hole 13. By pulling the second crossbar 12, the second crossbar 12 slides at the side end of the first crossbar 11. The length is adjusted through the hole of the pin. A return spring is installed on the side end of each spring block 16. The bottom end of the first crossbar 11 has a socket, and the top end of the pin block 14 is aligned with the socket.

[0028] Working principle:

[0029] First, pins are movably installed on the side ends of both the first crossbar 11 and the second crossbar 12. These pins connect to the connecting plate on the upright. The pins are inserted into the holes of the connecting plate, firmly connecting the crossbars to the upright. The length of the first crossbar 11 is 900mm, and the main body length of the second crossbar 12 is 880mm. By rotating the rotating rod 15, which is equipped with a bevel gear, the top of the rotating rod 15 is rotatably connected to the tops of the two drive shafts 18. By rotating the two drive shafts 18, the drive shafts 18 are positioned on the side of the pin block 14. The end rotates, simultaneously moving the support sleeve 19 into the pin block 14, causing the support sleeve 19 to leave the positioning hole 13. By pulling the pin block 14, the pin block 14 slides at the bottom end of the first horizontal bar 11, leaving the positioning hole 13. By pulling the second horizontal bar 12, the second horizontal bar 12 slides at the side end of the first horizontal bar 11. The length can be adjusted through the pin hole to three lengths: 900, 1200, and 1500 mm. The length can be freely adjusted according to the spacing between the uprights of the scaffold.

[0030] In the second step, a slot is provided at the bottom end of the first horizontal bar 11, which is aligned with the positioning hole 13. By moving the pin block 14, the pin block 14 is inserted into the bottom end of the first horizontal bar 11, and at the same time, the top end of the pin block 14 is inserted into the interior of the positioning hole 13. The bottom end of the first horizontal bar 11 presses against the spring button 16. A return spring is installed on the side end of the spring button 16. Under the action of the return spring, the spring button 16 slides into the end of the first horizontal bar 11. At the same time, a buffer is installed on the side end of the pin block 14. The buffer plate 17 can increase the friction between the pin block 14 and the positioning hole 13 to prevent shaking. At the same time, by rotating the rotating rod 15 in the opposite direction, the rotating rod 15 rotates in the opposite direction inside the pin block 14, driving the two drive shafts 18 to rotate at the side end of the pin block 14. Meanwhile, the surface of the drive shaft 18 fits with the support sleeve 19. The rotating drive shaft 18 generates a thrust on the support sleeve 19, causing the support sleeve 19 to rotate into the side end of the positioning hole 13, thus fixing the position of the second crossbar 12.

[0031] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
