Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building scaffolding connection components, and in particular to a right-angle coupler for scaffolding. Background Technology
[0002] As a core connecting component of steel pipe scaffolding, the reliability of scaffold couplers directly affects construction safety. Traditional right-angle couplers use threaded rods and nuts to connect the fixed ends, requiring repeated tightening and loosening of the nuts during construction. This is extremely inconvenient for high-altitude operations: firstly, tightening the nuts is time-consuming and labor-intensive, affecting erection efficiency; secondly, during disassembly, rust can easily cause the nuts to jam, requiring the use of tools for forceful removal, which carries the risk of component damage. Utility Model Content
[0003] The main purpose of this utility model is to propose a right-angle coupler for scaffolding, which aims to improve the convenience of coupler installation and removal.
[0004] To achieve the above objectives, the scaffolding right-angle coupler proposed in this utility model includes two vertically arranged fixed ends. Each fixed end includes a fixed buckle and a movable buckle. One end of the movable buckle is rotatably connected to one end of the fixed buckle. The other end of the movable buckle is provided with a hook, and the other end of the fixed buckle is provided with a locking groove. The hook is detachably hooked into the locking groove.
[0005] In one embodiment, a fixing frame protrudes from one end of the movable buckle toward the fixed buckle, and the hook is movably disposed on the fixing frame. The hook has an extended state and a retracted state. When the fixed end is in the locked state, the hook is in the extended state and hooks into the locking groove. When the movable buckle is opened, the hook changes from the extended state to the retracted state, so that the hook disengages from the locking groove.
[0006] In one embodiment, the hook is slidably disposed on the fixed frame, a spring is provided between the hook and the fixed frame, and the top of the hook is provided with an inclined surface. When the movable buckle is closed, the inclined surface contacts the opening of the locking groove and squeezes the hook back. After the hook is reset, it hooks onto the inner wall of the locking groove.
[0007] In one embodiment, the width of the fixing bracket and the hook is slightly smaller than the width of the movable buckle.
[0008] In one embodiment, the fixing frame has two sliding slots, and the bottom of the hook has two sliding plates protruding. The sliding plates are slidably disposed in the sliding slots to improve the sliding stability of the hook.
[0009] In one embodiment, the fixing frame has an enclosing frame at one end near the movable buckle, the enclosing frame partially enclosing one side of the hook, the enclosing frame being used to assist in guiding the hook.
[0010] In one embodiment, one end of the fixing buckle is provided with a guide frame, the locking groove is opened on one side of the guide frame, the top of the guide frame is provided with an opening, a button switch is slidably provided at the top opening of the guide frame, the bottom of the button switch contacts the hook, the top of the button switch extends to the top opening of the guide frame, pressing the button switch causes the hook to move downward to disengage from the locking groove, thereby opening the movable buckle and unlocking the movable buckle and the fixing buckle.
[0011] In one embodiment, the button switch has a pressing part and a contact part. The pressing part is slidably disposed in the top opening of the guide frame and is hollow. The contact part contacts the top of the hook.
[0012] In one embodiment, the contact part and the hook are made of metal. After the hook is squeezed and reset, it collidees with the contact part and makes a sound, which serves to remind that it has been locked in place.
[0013] In one embodiment, the top of the movable buckle and the guide frame is provided with an operating plate, which can be used by the operator to perform installation by pinching the two operating plates with one hand.
[0014] As can be seen from the above, the scaffolding right-angle coupler provided in this application, through the cooperation structure of the movable coupler and the fixed coupler with the hook and locking groove, combined with the button switch and guide frame design, realizes quick locking and unlocking, solves the problem of inconvenient operation of traditional couplers, and has the advantages of improving construction efficiency, facilitating one-handed operation, and providing a locking position indication.

[0022] Please see Figures 1 to 3 This application proposes a scaffolding right-angle coupler 1000, which includes two vertically arranged fixed ends. The fixed ends include a fixed buckle 1 and a movable buckle 2. One end of the movable buckle 2 is rotatably connected to one end of the fixed buckle 1. The other end of the movable buckle 2 is provided with a hook 21. The other end of the fixed buckle 1 is provided with a locking groove 12. The hook 21 is detachably hooked into the locking groove 12.
[0023] Specifically, the fixed end is connected through the cooperation of a fixed buckle 1 and a movable buckle 2, wherein the movable buckle 2 and the fixed buckle 1 are connected by a rotatable connection, allowing the movable buckle 2 to rotate relative to the fixed buckle 1. A hook 21 at the end of the movable buckle 2 and a locking groove 12 at the end of the fixed buckle 1 form a detachable locking structure. In a preferred embodiment, the hook 21 can be made of metal, possessing sufficient strength and wear resistance. The shape of the locking groove 12 matches the hook 21, ensuring that the hook 21 can be securely held within the locking groove 12. The rotatable connection can be achieved using a hinge structure or a pin connection, allowing the movable buckle 2 to open and close smoothly. The cooperation structure between the hook 21 and the locking groove 12 can be designed in various forms; for example, the hook 21 can be L-shaped or J-shaped, and the locking groove 12 can be correspondingly designed to accommodate and lock the hook 21.
[0024] This technical solution achieves rapid installation and disassembly through the rotatable connection between the movable buckle 2 and the fixed buckle 1, and the engagement of the hook 21 and the locking groove 12. Compared with the existing technology that requires multiple rotations of the nut for fixing, this solution only requires rotating the movable buckle 2 into place and engaging it with the hook 21 and the locking groove 12 to complete the fixing, greatly simplifying the operation. Especially in high-altitude working environments, this quick-connection method significantly improves construction efficiency and reduces operational difficulty.
[0025] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that a fixed frame 22 protrudes from one end of the movable buckle 2 toward the fixed buckle 1, and a hook 21 is movably disposed on the fixed frame 22. The hook 21 has an extended state and a retracted state. When the fixed end is in the locked state, the hook 21 is in the extended state and hooks into the locking groove 12. When the movable buckle 2 is opened, the hook 21 changes from the extended state to the retracted state, so that the hook 21 is disengaged from the locking groove 12.
[0026] The fixed frame 22, as an extension of the movable buckle 2, can be connected to the movable buckle 2 by welding or integral molding. The extension and retraction of the hook 21 can be achieved in the following ways: the hook 21 adopts an L-shaped metal sheet structure, with its horizontal section hinged to the fixed frame 22 via a pivot, and the end of its vertical section forming a hook-shaped structure; or it adopts a slider structure, with the hook 21 moving linearly on the fixed frame 22 via a slide rail. The spring 23 can be a compression spring or a torsion spring, installed between the hook 21 and the fixed frame 22 to provide a restoring force.
[0027] This technical solution achieves quick locking and unlocking of the fastener through the cooperation of the fixed bracket 22 and the movable hook 21. When the movable buckle 2 is closed, the hook 21 is automatically ejected by the spring 23 and engages with the locking groove 12 to complete the locking; when unlocking is required, the hook 21 is pressed back and disengaged from the locking groove 12, and the movable buckle 2 can be opened.
[0028] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the hook 21 is slidably disposed on the fixed frame 22, and a spring 23 is provided between the hook 21 and the fixed frame 22. The top of the hook 21 is provided with an inclined surface. When the movable buckle 2 is closed, the inclined surface contacts the opening of the locking groove 12 and squeezes the hook 21 to retract. After the hook 21 is reset, it hooks onto the inner wall of the locking groove 12.
[0029] The hook 21 is slidably mounted on the fixed frame 22. Specifically, a slide rail or groove can be provided on the fixed frame 22, and a corresponding slider or rod can be provided on the hook 21 to achieve up and down sliding. The spring 23 can be a compression spring or a torsion spring, and is provided between the bottom of the hook 21 and the fixed frame 22 to provide a return spring force.
[0030] Specifically, this technical solution achieves automatic locking when the movable buckle 2 is closed by setting up a sliding hook 21 and a spring 23 reset mechanism, combined with a sloped design. When the movable buckle 2 closes to the fixed buckle 1, the sloped surface of the hook 21 contacts the opening of the locking groove 12. Under the guidance of the sloped surface, the hook 21 is pressed downward and slides, compressing the spring 23. After the hook 21 passes the opening of the locking groove 12, it resets upward under the action of the spring 23 and automatically hooks onto the inner wall of the locking groove 12.
[0031] Please see Figure 2 and Figure 3 Furthermore, this application proposes that the width of the fixing bracket 22 and the hook 21 be slightly smaller than the width of the movable buckle 2. Designing a wider fixing bracket 22 and hook 21 improves hook stability.
[0032] Please see Figure 2 and Figure 3 Furthermore, this application proposes that the fixing frame 22 has two sliding slots, and the bottom of the hook 21 is provided with two sliding plates 24, which are slidably disposed in the sliding slots to improve the sliding stability of the hook 21. Thus, through the cooperative structure of the double sliding slots and the double sliding plates 24, the deflection and swaying of the hook 21 during movement are effectively limited.
[0033] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the fixed frame 22 is provided with an enclosing frame 25 at one end near the movable buckle 2, the enclosing frame 25 partially enclosing one side of the hook 21, and the enclosing frame 25 is used to assist in guiding the hook 21.
[0034] The enclosure frame 25 can be manufactured using metal stamping or injection molding processes, and its semi-enclosed structure can be designed as a U-shaped groove or an L-shaped baffle structure. In a preferred embodiment, the enclosure frame 25 is fixedly connected to the fixing frame 22 by welding or bolting, with the opening of the U-shaped groove facing the movement path of the hook 21. This technical solution, by adding a semi-enclosed enclosure frame 25, effectively solves the technical problem of the hook 21 easily becoming misaligned during sliding.
[0035] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that one end of the fixed buckle 1 is provided with a guide frame 11, a slot 12 is opened on one side of the guide frame 11, the top of the guide frame 11 is provided with an opening, a button switch 13 is slidably provided at the top opening of the guide frame 11, the bottom of the button switch 13 contacts the hook 21, the top of the button switch 13 extends to the top opening of the guide frame 11, pressing the button switch 13 causes the hook 21 to move downward to disengage from the slot 12, thereby opening the movable buckle 2 and completing the unlocking of the movable buckle 2 and the fixed buckle 1.
[0036] This technical solution achieves one-handed unlocking by incorporating a button switch 13 mechanism. Specifically, when it is necessary to disassemble the fastener, simply press the button switch 13 on the top of the guide frame 11 to drive the hook 21 down and disengage it from the locking slot 12. Compared to the traditional method of loosening nuts, this reduces the number of steps and eliminates the need for tools. This design significantly simplifies disassembly operations during high-altitude work and improves construction efficiency.
[0037] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the push-button switch 13 is provided with a pressing part 131 and a contact part 132. The pressing part 131 is slidably disposed in the top opening of the guide frame 11 and is hollow. The contact part 132 contacts the top of the hook 21. The contact part 132 and the hook 21 are made of metal. After the hook 21 is pressed and reset, it collidees with the contact part 132 to make a sound, which serves to indicate that it has been locked in place.
[0038] Specifically, the contact part 132 and the hook 21 are made of metal, such as stainless steel or carbon steel, to ensure sufficient sound upon impact. After being pressed and reset, the hook 21 moves upward quickly due to the elastic force of the spring 23 and collides with the contact part 132. The metal contact part 132 and the hook 21 produce a crisp metallic sound upon impact, thus reminding the worker that the hook 21 is properly engaged. In environments with limited visibility, such as high-altitude operations, auditory feedback is particularly important, helping workers quickly confirm whether the fastener is installed correctly and avoiding tedious repeated checks.
[0039] Please see Figure 1Furthermore, this application also proposes that the top of the movable buckle 2 and the guide frame 11 is provided with an operating plate 3, which can be used by the staff to perform installation by pinching the two operating plates 3 with one hand.
[0040] The specific implementation of the control panel 3 may include: the control panel 3 being integrally formed with the movable buckle 2 and the guide frame 11, and fixed by welding or bolts; the surface of the control panel 3 being provided with anti-slip textures or rubber pads to enhance grip friction; the control panel 3 being arc-shaped or flat to accommodate different hand shapes; the control panel 3 being made of lightweight metal or engineering plastic to balance strength and weight. As a preferred embodiment, the control panel 3 is positioned symmetrically on the movable buckle 2 and the guide frame 11, facilitating single-handed application of force.
[0041] Specifically, this technical solution adds an operating plate 3 to the top of the movable buckle 2 and the guide frame 11, allowing workers to simultaneously grasp both operating plates 3 with one hand to complete the fastener closure action. Compared with the existing technology that requires two hands to operate the fixed buckle 1 and the movable buckle 2 respectively, this design significantly simplifies the installation process. Especially when working at heights, single-handed operation improves efficiency and reduces safety risks.
[0042] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and 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.
