Description

Technical Field

[0001] This utility model relates to a fixing buckle, specifically a quick fixing buckle for building scaffolding, belonging to the field of building construction scaffolding technology. Background Technology

[0002] As a core temporary support facility in building construction, the reliability of the node connections of scaffolding directly determines the safety of the scaffolding. As a key component of node connections, the performance defects of the fixing clips have become one of the main causes of safety accidents.

[0003] Existing scaffolding fixing clips lack sufficient self-locking reliability in practical use. Most clips rely on a single locking structure, making them prone to loosening under vibration and load changes. The risk of detachment increases significantly, especially after prolonged use or slight deformation of the steel pipes. Furthermore, the anti-detachment design is inadequate, making the steel pipes susceptible to slippage under lateral forces, thus affecting the overall stability of the scaffolding. Therefore, this paper proposes a quick-locking clip for building scaffolding. Utility Model Content

[0004] This utility model proposes a quick-fixing buckle for building scaffolding to solve the problems of insufficient self-locking reliability and imperfect anti-derailment design in the prior art.

[0005] This utility model is achieved through the following technical solution: a quick-fixing buckle for building scaffolding, including a fixing base, wherein the fixing base is provided with a self-locking mechanism; The self-locking mechanism includes two fitting grooves, each of which is opened inside the fixed base. A transmission rod is rotatably connected inside the fixed base. A fixed block is fixedly connected to the outer surface of the transmission rod. An arc-shaped plate is fixedly connected to the inner bottom wall of the fixed base. Two positioning rods are slidably connected inside the fixed block. A connecting column is fixedly connected to the end of each of the two positioning rods that is close to each other. A return spring is fixedly connected to the end of each of the two connecting columns that is close to each other. The ends of the two return springs that are far apart from each other are fixedly connected to the inner side wall of the fixed base. An anti-detachment component is provided above the fixing base.

[0006] Each of the fitting grooves has a first protective pad fixedly connected to its inner wall, and each of the first protective pads has a plurality of first anti-slip protrusions arranged at equal intervals fixedly connected to its inner wall.

[0007] An auxiliary bearing is fitted onto the outer surface of the transmission rod, and the auxiliary bearing is embedded inside the fixed base.

[0008] The inner wall of the arc-shaped plate is fixedly connected to a second protective pad, and the inner wall of the second protective pad is fixedly connected to a plurality of second anti-slip protrusions arranged at equal intervals.

[0009] Each of the connecting posts has a push handle fixedly connected to its outer surface, and each push handle is slidably connected to the inside of the fixed block.

[0010] The anti-detachment component includes an anti-detachment block, which is fixedly connected to the outer surface of the fixing block. Two anti-detachment cylinders are slidably connected inside the fixing base. Each anti-detachment cylinder extends into the interior of the fixing base. An anti-detachment spring is fixedly connected to one end of each anti-detachment cylinder that is far apart from the other. The ends of each anti-detachment spring that are far apart from the other are fixedly connected to the inner wall of the fixing base.

[0011] This utility model provides a quick-fixing clip for building scaffolding, which has the following beneficial effects: This quick-locking buckle for the building scaffolding solves the problem of easy loosening of existing buckle single locking structures through a multi-coordinated self-locking mechanism. The positioning rod and the return spring form an elastic locking force, which, together with the clamping effect of the fixing block and the arc plate, can maintain a stable locking state even if the scaffolding is used for a long time or the steel pipe is slightly deformed, greatly reducing the risk of falling off. The anti-falling component builds a secondary protective barrier. The combination design of the anti-falling block, anti-falling cylinder and anti-falling spring can effectively resist the lateral force on the steel pipe, prevent slippage, ensure the overall stability of the scaffolding, and make up for the defects of the existing buckle anti-falling design.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0015] Please see Figures 1-4 This utility model embodiment provides a quick-fixing buckle for building scaffolding, including a fixing base 1, and a self-locking mechanism 2 is provided inside the fixing base 1; The self-locking mechanism 2 includes two fitting grooves 201, each of which is located inside the fixed base 1. A first protective pad 4 is fixedly connected to the inner wall of each fitting groove 201. A plurality of first anti-slip protrusions 5 are fixedly connected to the inner wall of each first protective pad 4. The first protective pad 4 is fixed to the inner wall of the fitting groove 201 and is made of elastic material. It can form a buffer layer when the steel pipe contacts the fitting groove 201 to avoid surface damage caused by rigid collision between the two. At the same time, it can accommodate slight dimensional deviations of the steel pipe and improve the fit. The plurality of first anti-slip protrusions 5 arranged at equal distances increase the contact friction with the surface of the steel pipe and further restrict the displacement of the steel pipe in the locked state. In particular, it can resist slight loosening caused by vibration. Together with the self-locking mechanism 2, it enhances the overall locking reliability.

[0016] A transmission rod 202 is rotatably connected inside the fixed base 1. A fixed block 203 is fixedly connected to the outer surface of the transmission rod 202. An auxiliary bearing 6 is sleeved on the outer surface of the transmission rod 202 and embedded inside the fixed base 1. The core function of the auxiliary bearing 6 is to reduce the frictional resistance when the transmission rod 202 rotates, so that the opening and closing operation of the fixed block 203 is more effortless and smooth, and the installation and disassembly efficiency is improved.

[0017] An arc-shaped plate 204 is fixedly connected to the inner bottom wall of the fixed base 1. Two positioning rods 205 are slidably connected inside the fixed block 203. A second protective pad 7 is fixedly connected to the inner wall of the arc-shaped plate 204. Multiple second anti-slip protrusions 8 arranged at equal intervals are fixedly connected to the inner wall of the second protective pad 7. The second protective pad 7 is fixed to the inner wall of the arc-shaped plate 204, forming a symmetrical protective structure with the first protective pad 4. It protects the steel pipe from the other side, preventing the steel pipe from being indented or damaged due to excessive pressure during clamping. At the same time, it enhances the tightness of the fit. The second anti-slip protrusions 8 and the first anti-slip protrusions 5 cooperate with each other to form a double anti-slip effect from the two contact surfaces of the fitting groove 201 and the arc-shaped plate 204, further increasing the friction force and effectively preventing the steel pipe from slipping under the action of lateral force, thus improving the stability of the scaffold node connection.

[0018] Two positioning rods 205 are fixedly connected to a connecting post 206 at their close ends, and a return spring 207 is fixedly connected to the close ends of the two connecting posts 206. The two return springs 207 are fixedly connected to the inner side wall of the fixed base 1 at their far ends. A push handle 9 is fixedly connected to the outer surface of each connecting post 206. Each push handle 9 is slidably connected to the inside of the fixed block 203. The push handle 9 is fixed to the outer surface of the connecting post 206 and slidably connected to the inside of the fixed block 203, providing a convenient operating component for adjusting the positioning rods 205. Construction personnel can directly control the extension and retraction of the positioning rods 205 by manually pushing the handle 9. An anti-detachment component 3 is provided above the fixed base 1. The anti-detachment component 3 includes an anti-detachment block 301, which is fixedly connected to the outer surface of the fixed block 203. Two anti-detachment cylinders 302 are slidably connected inside the fixed base 1. Each anti-detachment cylinder 302 extends into the interior of the fixed base 1. An anti-detachment spring 303 is fixedly connected to the ends of the two anti-detachment cylinders 302 that are far apart from each other. The ends of the two anti-detachment springs 303 that are far apart from each other are fixedly connected to the inner wall of the fixed base 1. The anti-detachment block 301 is fixed to the outer surface of the fixed block 203 and rotates synchronously with the fixed block 203. When the fixed block 203 rotates... When 03 is in the locked position, the anti-detachment block 301 will engage with the anti-detachment cylinder 302, forming a secondary anti-detachment barrier. The anti-detachment cylinder 302 will always remain extended under the elastic action of the anti-detachment spring 303, and can automatically engage with the corresponding position of the anti-detachment block 301, restricting the reverse rotation of the fixing block 203 and preventing the fixing block 203 from loosening due to vibration, load changes, or other factors. When disassembly is required, external force is applied to push the anti-detachment cylinder 302 to compress the anti-detachment spring 303, which will release the engagement without affecting normal operation and effectively solve the problem of imperfection in the existing buckle anti-detachment design.

[0019] In use, the following steps are taken: Initially, the return spring 207 is in a naturally extended state, causing the connecting column 206 and positioning rod 205 to remain extended. The anti-detachment spring 303 is also in a naturally extended state, pushing the anti-detachment cylinder 302 to extend to a preset position inside the fixed seat 1. The fixed block 203 is in an open state under the support of the transmission rod 202, forming a space between the fitting groove 201 and the arc plate 204 for inserting the steel pipe. Construction workers align the scaffolding steel pipe to be connected with the space between the fitting groove 201 and the arc plate 204 inside the fixed seat 1, and slowly insert the steel pipe until it is completely fitted with the first protective pad 4 and the second protective pad 7. At this point, the first anti-slip protrusion 5 and the second anti-slip protrusion 8 have contacted the surface of the steel pipe, initially increasing friction and preventing the steel pipe from slipping. By shaking it freely and manually rotating the transmission rod 202, under the action of the auxiliary bearing 6, the transmission rod 202 rotates smoothly and drives the fixed block 203 to flip towards the steel pipe. As the fixed block 203 flips, its inner wall gradually approaches the surface of the steel pipe, while pushing the positioning rod 205 to press towards the steel pipe. After the positioning rod 205 is subjected to the reaction force of the steel pipe, it compresses the return spring 207 through the connecting column 206. The return spring 207 generates a reverse elastic force, pushing the positioning rod 205 to press tightly against the surface of the steel pipe. When the fixed block 203 rotates to the fully locked position, the positioning rod 205 remains pressed under the action of the elastic force of the return spring 207, forming a three-point clamping structure together with the fixed block 203 and the arc plate 204 to achieve a self-locking function, ensuring that the steel pipe is firmly fixed and not easy to loosen. When the fixing block 203 rotates to the locked position, the anti-detachment block 301 on its outer surface rotates synchronously to the corresponding position of the anti-detachment cylinder 302. Under the elastic thrust of the anti-detachment spring 303, the anti-detachment cylinder 302 automatically engages in the slot of the anti-detachment block 301, restricting the reverse rotation of the anti-detachment block 301 and the fixing block 203. Even if the scaffolding is affected by vibration, lateral force, or load changes during use, the engagement relationship between the anti-detachment cylinder 302 and the anti-detachment block 301 can effectively prevent the fixing block 203 from loosening, forming secondary protection and further ensuring the reliability of locking. To prevent the steel pipe from slipping or the buckle from falling off, during disassembly, the construction personnel first press the anti-detachment cylinder 302 on both sides to compress the anti-detachment spring 303, causing the anti-detachment cylinder 302 to disengage from the slot of the anti-detachment block 301 and release the anti-detachment lock. Then, by pushing the handle 9 inward to push the connecting column 206, the positioning rod 205 is driven to retract and compress the reset spring 207, releasing the clamping force of the positioning rod 205 on the steel pipe. Finally, the transmission rod 202 is rotated in the opposite direction, and under the action of the auxiliary bearing 6, the fixing block 203 is opened, and the steel pipe can be taken out from the fixing seat 1 to complete the disassembly.
