Description

Technical Field

[0001] This utility model relates to the field of scaffolding installation, and in particular to an anti-slip locking device for irregularly shaped fasteners. Background Technology

[0002] Scaffolding is an important component of building construction, and its main function is to provide a safe working platform for construction workers. Traditional scaffolding systems usually consist of uprights, horizontal bars, and couplers. Couplers play a crucial role in the connection of scaffolding, mainly used to connect uprights and horizontal bars to ensure the stability and safety of the scaffolding structure.

[0003] During the installation of existing scaffolding coupler devices, the operator typically needs to hold the half-hoop with one hand to keep it in the correct position, while the other hand is responsible for installing the bolts. Due to the lack of an effective positioning device in the coupler design, the half-hoop is prone to displacement or movement when not in a restrained state, leading to instability during the assembly process. This installation method not only increases the operator's labor intensity, but is also particularly difficult to operate in high-altitude or confined spaces, greatly reducing construction efficiency. Utility Model Content

[0004] The main purpose of this utility model is to propose an anti-slip locking device for irregularly shaped fasteners, which aims to solve the problems existing in the prior art.

[0005] To solve the above problems, this utility model proposes an anti-slip locking device for irregularly shaped fasteners, including: a connecting pin, a rotating shaft, a first half hoop and a second half hoop, wherein a first limiting device is fixedly provided on the top of one side of the first half hoop, and a second limiting device is fixedly provided on the top of one side of the second half hoop. The first half hoop has a connection port on one side, and the second half hoop has a connecting block fixedly installed on one side. The connecting block cooperates with the connection port, and the connecting pin passes through the connection port to achieve a limiting connection with the connecting block. Multiple anti-slip strips are fixedly installed on one side of the inner wall of both the first half hoop and the second half hoop.

[0006] In one embodiment, the first limiting device includes a first limiting block. A transverse groove is provided through one side of both the first limiting block and the second limiting device. A connecting shaft is fixedly installed in the transverse groove of the first limiting block. A sleeve is sleeved on the connecting shaft. A threaded rod is fixedly installed on one side of the sleeve. A pressure plate is threadedly connected to one side of the threaded rod. A bolt is fixedly installed on one side of the pressure plate.

[0007] In one embodiment, the second limiting device includes a second limiting block. The upper and lower inner walls of the transverse groove of the second limiting block are provided with mounting grooves. Limiting clamps are fixedly installed in both mounting grooves. A connecting groove is opened on the top surface of one side of the two limiting clamps. A spring piece is fixedly installed in the connecting groove. The other side of the spring piece is fixedly connected to the top surface of the mounting groove for elastic clamping and limiting of the threaded rod.

[0008] In one embodiment, a bearing for mounting a rotating component is fixedly provided on one side of the second half-hoop on one side. The bearing has a bearing seat inside, and a rolling bearing is fixedly installed in the bearing seat. One end of the rotating shaft is inserted into the rolling bearing and connected with it, thereby realizing the rotatable connection of the rotating shaft in the bearing. The second half-hoop on the other side also has a bearing with the same structure, which is used to rotatably connect with the other end of the rotating shaft. The two ends of the rotating shaft are respectively embedded in the bearings on the second half-hoops of the two fasteners, thereby realizing the universal rotation adjustment capability between the two fasteners, ensuring that it can automatically adapt and be firmly connected according to the included angle between the horizontal and vertical bars of the scaffold during installation.

[0009] In one embodiment, the first half-hoop and the second half-hoop are connected by a connecting block and a connecting pin. The connecting structure allows the first half-hoop to be adjusted in angle or spacing relative to the second half-hoop to accommodate fixed rods of different sizes. Beneficial effects

[0010] 1. Through the cooperation of the spring piece and the limiting clamp in the second limiting device, when the threaded rod of the first half hoop rotates into the transverse groove, it will be squeezed by the upper and lower limiting clamps. When the threaded rod rotates and enters the transverse groove, the limiting clamp will move backward under the compression, thereby compressing the spring piece. This compression action generates a forward thrust, squeezing the threaded rod and restricting its free movement, ensuring that the threaded rod remains in a fixed position during installation and does not experience unnecessary deviation or loosening. This avoids frequent adjustments and manual support operations, significantly reducing work fatigue during installation. Installers no longer need to support the fastener components by hand, making the operation more efficient and stable, and greatly improving the overall installation efficiency.

[0014] 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.

[0015] To achieve the above-mentioned utility model objectives, such as Figure 1-3As shown, this utility model provides an anti-slip locking device for irregularly shaped fasteners, including: a connecting pin 7, a first half-hoop 1, and a second half-hoop 2. A first limiting device 3 is fixedly installed at the top of one side of the first half-hoop 1, and a second limiting device 4 is fixedly installed at the top of one side of the second half-hoop 2. A connecting port is opened on one side of the first half-hoop 1, and a connecting block 201 is fixedly installed on one side of the second half-hoop 2. The connecting block 201 cooperates with the connecting port, and the connecting pin 7 passes through the connecting port and connects to the connecting block 201 to achieve a limiting connection. Multiple anti-slip strips 101 are fixedly installed on one side of the inner wall of both the first half-hoop 1 and the second half-hoop 2. The first limiting device 3 includes a first limiting block 301, and both the first limiting block 301 and the second limiting device 4 have a connecting pin 7 on one side. The first limiting block 301 has a horizontal groove. A connecting shaft 302 is fixedly installed in the horizontal groove. A sleeve 303 is fitted over the connecting shaft 302. A threaded rod 304 is fixedly installed on one side of the sleeve 303. A pressure plate 305 is threadedly connected to one side of the threaded rod 304. A bolt 306 is fixedly installed on one side of the pressure plate 305. The second limiting device 4 includes a second limiting block 401. The upper and lower inner walls of the horizontal groove of the second limiting block 401 are provided with mounting grooves. Limiting clamps 403 are fixedly installed in both mounting grooves. A connecting groove is opened on the top surface of one side of the two limiting clamps 403. A spring piece 402 is fixedly installed in the connecting groove. The other side of the spring piece 402 is fixedly connected to the top surface of the mounting groove for elastically clamping and limiting the threaded rod 304.

[0016] Specifically, this device consists of two fasteners, one for horizontal installation and one for vertical installation. These fasteners reliably clamp and adjust the angle at the junction of horizontal and vertical members in the scaffolding structure. The two fasteners are connected by a bearing 6 and a rotating shaft 5 located on one side of the two second half-hoops 2, forming a universally adjustable structure. The included angle between the two fasteners can be adjusted according to actual usage needs, facilitating the adaptation of horizontal members connected at different angles. In operation, the first half-hoop 1 is first pried open by applying force, causing it to rotate around the connecting block 201 and connecting pin 7, thus opening it up. This facilitates the insertion of the target member into the device for initial positioning. Subsequently, the operator pushes the threaded rod 304 located in the first limiting device 3. The threaded rod 304 rotates with the connecting shaft 302 through the externally sleeved sleeve 303, gradually inserting into the horizontal groove located in the second limiting device 4. After the threaded rod 304 enters the transverse groove, the two limiting clamps 403 set on the upper and lower inner walls of the transverse groove move backward due to compression, thereby compressing the spring piece 402 installed in the connecting groove. The spring piece 402 generates a continuous forward thrust during the compression process, thereby forming a reverse limiting and clamping on the threaded rod 304 to prevent it from shaking or loosening during clamping. Then, the tool is used to rotate the bolt 306, which drives the pressure plate 305 located at one end of the threaded rod 304 to move along the thread direction and finally adhere to and press against the outer wall surface of the second limiting block 401. Through the multi-point limiting and clamping of the above structure, the first half-hoop 1 and the second half-hoop 2 are firmly locked, thereby effectively fixing the crossbar. In addition, the anti-slip strip 101 set on one side of the inner wall of the first half-hoop 1 and the second half-hoop 2 can enhance the friction during clamping, further improving the overall fixing stability and anti-slip ability of the fastener.

[0017] To achieve the above-mentioned utility model objectives, such as Figure 1-4 As shown, this utility model provides an anti-slip locking device for irregularly shaped fasteners. One side of the second half-hoop 2 is fixedly provided with a bearing 6 for installing rotating components. The bearing 6 has a bearing seat inside, and a rolling bearing is fixedly installed in the bearing seat. One end of the rotating shaft 5 is inserted into the rolling bearing and connected with it, thereby realizing the rotatable connection of the rotating shaft 5 in the bearing 6. The other side of the second half-hoop 2 also has a bearing 6 with the same structure, which is used to rotatably connect with the other end of the rotating shaft 5. The two ends of the rotating shaft 5 are respectively embedded in the bearing 6 on the second half-hoops 2 of the two fasteners, thereby realizing the universal rotation adjustment capability between the two fasteners. This ensures that during the installation process, it can automatically adapt and be stably connected according to the included angle between the horizontal and vertical bars of the scaffold. The first half-hoop 1 and the second half-hoop 2 are connected by a connecting block 201 and a connecting pin 7. The mating structure allows the first half-hoop 1 to be adjusted in angle or spacing relative to the second half-hoop 2 to adapt to fixed rods of different sizes.

[0018] Specifically, when disassembling this device, the operator first uses the adapter tool to rotate the bolt 306, causing it to drive the pressure plate 305 to move in the opposite direction along the threaded rod 304, thereby gradually moving away from the second limiting block 401 on the second limiting device 4 and releasing the clamping state. Then, the operator manually moves the threaded rod 304 to disengage it from the transverse groove in the second limiting device 4. Because the limiting clamp 403 has an arc-shaped structure and is located on the upper and lower inner walls of the transverse groove, it has good elastic fit performance. During the process of the threaded rod 304 disengaging from the transverse groove, the limiting clamp 403 can spring back smoothly without damaging the spring plate 402 structure, allowing the threaded rod 304 to disengage smoothly, thereby completing the unlocking process between the first half-clamp 1 and the second half-clamp 2, improving the convenience and smoothness of the overall operation. To ensure the device maintains good structural reliability during long-term use in outdoor construction environments, the main components, such as the first half-hoop 1, the second half-hoop 2, the bearing 6, the rotating shaft 5, the connecting pin 7, the first limiting device 3, and the second limiting device 4, are preferably made of stainless steel, hot-dip galvanized steel, or composite anti-rust alloy materials. These materials not only have excellent mechanical strength but also good oxidation and corrosion resistance, making them particularly suitable for use in rainy, humid, high-temperature, or dusty environments. This effectively extends the device's lifespan and reduces maintenance frequency. The spring 402 and the limiting chuck 403 are preferably made of elastic alloy steel. This structural material maintains good elastic recovery performance and has certain wear resistance, ensuring stable limiting and clamping functions even during frequent disassembly and assembly.

[0019] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
