Description

Technical Field

[0001] This utility model belongs to the technical field of disc-lock scaffolding, specifically relating to a disc-lock scaffolding that is easy to disassemble. Background Technology

[0002] Disc-lock scaffolding ladder hooks are a common type of scaffolding safety equipment used to connect ladders to scaffolding and provide stable and reliable support. Compared to traditional bolt hooks, disc-lock scaffolding ladder hooks offer a more convenient and quick connection method, allowing for faster installation and disassembly. Disc-lock scaffolding ladder hooks typically consist of two parts: one that connects to the horizontal bar of the scaffolding and the other that connects to the ladder. Both parts have a special disc-lock structure that allows for quick connection and secure fixation via a locking device.

[0003] Patent application number 202420610966.6 discloses a disc-lock type scaffolding ladder hook, including a first fixing ring. A collar is fixedly connected to one side of the outer wall of the first fixing ring. A sleeve rod is slidably connected to one side of the inner wall of the collar. A second fixing ring is fixedly connected to one side of the sleeve rod. The collar has a ring array of slots inside. A driving block is rotatably connected to one side of the inner wall of the second fixing ring. A positive and negative threaded rod is rotatably connected to one side of the inner wall of the second fixing ring. One side of the positive and negative threaded rod is fixedly connected to one side of the outer wall of the driving block. Moving rings are threaded to both sides of the outer wall of the positive and negative threaded rod.

[0004] The above technical solution uses bolts to fix the ring-shaped buckles to the scaffolding. When dismantling the scaffolding, a wrench is needed to remove the bolts. However, the bolts will rust after being used outdoors for a long time, and the bolts need to be tightened very tightly in order to keep the scaffolding stable, which makes it very difficult to remove the bolts from the buckles. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a disc-lock scaffold that is easy to disassemble. This disc-lock scaffold aims to solve the technical problem that in the existing technology, bolts will rust after long-term outdoor use, and in order to keep the scaffold stable, the bolts need to be tightened very tightly, which makes it very difficult to disassemble the bolts on the clips.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a detachable disc-lock scaffolding. The detachable disc-lock scaffolding includes multiple support rods arranged in a rectangular array and crossbars installed between two adjacent support rods. The support rods are fixed with locking discs at equal intervals. Multiple first grooves are formed in a circular array on the locking discs. Both ends of the crossbars are fixed with locking blocks sleeved on the locking discs. The top of the locking block is provided with a positioning rod that is inserted into the first groove. The bottom end of the positioning rod passes through the locking block and is equipped with a positioning pin mechanism.

[0009] When using this technical solution, by fixing buckles at equal intervals on the support rods, during scaffolding installation, the locking blocks on the crossbars slide onto the buckles, so that the second groove on the locking block corresponds to the first groove on the buckle. The positioning rod is inserted between the first and second grooves, and the connecting pin is inserted into the connecting hole at the bottom of the positioning rod. At the same time, the pin is inserted into the insertion hole on the connecting pin. When disassembling the scaffolding, the pull buckle part drives the arc-shaped elastic part to separate from the side wall of the positioning pin, and the pin slides out of the insertion hole. At the same time, the positioning pin is pulled out from the connecting hole, and the positioning rod is pulled out from between the first and second grooves. This also separates the locking block from the buckle, which facilitates the disassembly and separation of the support rods and crossbars that make up the scaffolding, improving the convenience of scaffolding assembly and disassembly.

[0010] Preferably, each of the support rods has a base fixed to its bottom end, and the support rod has a through hole.

[0011] Furthermore, the side wall of the card block is provided with a duckbill groove, and the card block is fitted onto the buckle plate through the duckbill groove, and the top of the card block is provided with a second groove.

[0012] Furthermore, the positioning rod is slidably inserted into the second groove, and the top end of the positioning rod is provided with a protrusion, wherein the bottom end of the positioning rod is provided with a connecting hole.

[0013] Furthermore, the positioning pin mechanism includes a connecting pin inserted into the positioning hole and a locking pin engaged in the connecting pin, with the top end of the connecting pin abutting against the locking block.

[0014] Furthermore, one end of the connecting pin protrudes, and the other end of the connecting pin has a socket for accommodating the pin.

[0015] Furthermore, one end of the pin is slidably inserted into the socket, and the other end of the pin is provided with an arc-shaped elastic part sleeved on the connecting pin, and a pull buckle is fixed at the bottom end of the arc-shaped elastic part.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features equidistant locking plates fixed to the support rods. During scaffolding installation, the locking blocks on the crossbars slide onto the locking plates, aligning the second groove on the locking blocks with the first groove on the locking plates. A positioning rod is inserted between the first and second grooves, and a connecting pin is inserted into the connecting hole at the bottom of the positioning rod. Simultaneously, a pin is inserted into the insertion hole on the connecting pin. When disassembling the scaffolding, the pull-locking part causes the arc-shaped elastic part to separate from the side wall of the positioning pin, and the pin slides out of the insertion hole. At the same time, the positioning pin is pulled out of the connecting hole, and the positioning rod is pulled out from between the first and second grooves, thus separating the locking blocks from the locking plates. This facilitates the disassembly and separation of the support rods and crossbars that constitute the scaffolding, improving the convenience of scaffolding assembly and disassembly.
