Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a scaffolding coupler that is easy to assemble and disassemble. Background Technology

[0002] Couplers are used during scaffolding construction. The connection between the couplers and the scaffolding is made by bolts and nuts. The couplers are frequently disassembled and assembled, which is time-consuming and labor-intensive. Moreover, the nuts are prone to stripping, which will cause inconvenience for the next disassembly and assembly.

[0003] A search revealed Chinese patent publication number CN221778978U, which discloses a fastener for construction scaffolding. This patent utilizes a fixing assembly to stably fix clamp one and clamp two to the outside of a steel pipe. A first nut and a second nut engage with the threaded connection of a fixing screw. Even if one nut slips on the thread, the other nut remains stably connected to the outside of the fixing screw, ensuring connection stability. Furthermore, the use of an arc-shaped groove, arc-shaped block, protrusion, and fixing screw allows for replacement of the fixing screw if it slips.

[0004] However, although the screw is reinforced by a double layer of first and second nuts when the above device is in use, as can be seen from the attached drawings of the patent, the first nut is small and inconvenient to rotate and install. Moreover, during use, the first and second nuts may still loosen when shaking occurs, which will affect the stability of the overall device. Utility Model Content

[0005] This utility model proposes a scaffolding coupler that is easy to assemble and disassemble, which has the advantages of quick installation and disassembly of scaffolding couplers and improved stability after installation. It solves the problems of scaffolding couplers being unable to be quickly disassembled and installed and having poor stability after installation.

[0006] The technical solution of this utility model is as follows: A scaffolding fastener that is easy to assemble and disassemble includes a left arc-shaped block. A right arc-shaped block is rotatably mounted on the rear side of the left arc-shaped block via a pivot. Magnets are fixedly installed in the inner cavities of both the left and right arc-shaped blocks. Rubber blocks are fixedly installed in the middle of the inner walls of both the left and right arc-shaped blocks. A left strip block is fixedly mounted on the front side of the left arc-shaped block. A first circular hole is opened in the middle of the left side of the left strip block. A limit hole is opened on the rear side of the left side of the left strip block. A gasket is detachably installed on the right side of the inner cavity of the first circular hole. A nut is detachably installed on the left side of the inner cavity of the first circular hole. The rear side of the left side of the nut is fixed. A limit block is installed. A right strip block is fixedly installed on the front side of the right arc block. A second circular hole is opened in the middle of the right side of the right strip block. Through holes are opened on the left side of the inner cavity of the second circular hole and the right side of the inner cavity of the first circular hole. Multiple locking holes are fixedly installed on the right side of the right strip block. A bolt is detachably installed in the inner cavity of the second circular hole. A groove is opened in the middle of the right side of the bolt. A spring is fixedly installed on the left side of the inner cavity of the groove. An extension block is fixedly installed on the other side of the spring. A rotating ring is fixedly installed on the other side of the extension block. Locking rods are fixedly installed on the upper and lower sides of the outer surface of the rotating ring. A sloping groove is opened at the bottom of the inner cavities of the first and second circular holes.

[0007] Preferably, the left and right arc-shaped blocks are matched in position and shape with the left and right strip blocks. The inner cavity cross-section of the combined left and right arc-shaped blocks is circular. Thus, when in use, after the left and right arc-shaped blocks are rotated and fitted together, the scaffolding is fixed by using the fitted left and right strip blocks.

[0008] Preferably, the depth of the inner cavity of the first circular hole matches the length of the combined gasket and nut, and the shape of the outer surface of the limiting block matches the shape of the inner cavity of the limiting hole. Thus, when in use, after the nut is installed into the inner cavity of the first circular hole, the limiting block extends into the inner cavity of the limiting hole to fix the position of the nut and prevent the nut from rotating easily after it is fixed.

[0009] Preferably, the perforation extends through the left side of the right strip block and the inner cavity of the second round hole, as well as the right side of the left strip block and the inner cavity of the first round hole. After the perforation and the second round hole are combined, the shape of the inner cavity matches the shape of the outer surface of the bolt, and the length of the bolt matches the length between the inner cavities of the first round hole and the second round hole after combination. Thus, in use, the bolt extends into the inner cavity of the second round hole and through the perforation into the inner cavity of the first round hole, thereby connecting the left strip block and the right strip block.

[0010] Preferably, the locking holes are evenly distributed around the second circular hole, and the shape of the inner cavity of the locking hole matches the shape of the outer surface of the locking rod. Thus, when in use, after the locking rod is inserted into the inner cavity of the locking hole, the bolt is fixed in this way, preventing the bolt from rotating and loosening.

[0011] Preferably, the extension block and the swivel are connected to the right side of the bolt via a spring. The length of the extension block in the inner cavity of the groove is greater than the stretchable length of the spring, and the stretchable length of the spring is less than the depth of the inner cavity of the groove. Thus, during use, the right side of the extension block will not move out of the inner cavity of the groove due to the stretchable length of the spring and the length of the extension block.

[0012] Preferably, the depth of the inner cavity of the card hole is less than the stretchable length of the spring, so that when in use, pulling the swivel ring to the right can move the card rod out of the card hole without the extension block moving out of the inner cavity of the groove. At this time, the swivel ring can drive the bolt to rotate through the extension block.

[0013] Preferably, the upper and lower sides of the outer surface of the rubber block are frosted surfaces, and the middle part of the outer surface of the rubber block is a smooth surface. The rubber block is constructed of synthetic rubber material. In use, the rubber block increases the friction between the left and right arc-shaped blocks and the outer surface of the scaffold, thereby improving the stability of the scaffold when it is fixed.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] This easy-to-assemble and disassemble scaffolding coupler uses a combination of a swivel structure and a locking rod structure. During operation, the swivel rotates the bolt, thereby controlling the rapid assembly or disassembly of the bolt and nut. After assembly, the swivel is released, and under the elastic force of the spring, the locking rod extends into the locking hole to fix the swivel and thus the bolt, preventing the bolt from rotating during use. With the help of the limit block and limit hole, the nut is fixed. When disassembly is required, simply pull the swivel to the right to rotate the bolt, facilitating the separation of the bolt and nut. This achieves the effect of rapid installation and disassembly of scaffolding couplers and improves the stability after installation. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-5As shown, a scaffolding coupler that is easy to assemble and disassemble includes a left arc-shaped block 1. A right arc-shaped block 101 is rotatably mounted on the rear side of the left arc-shaped block 1 via a pivot. Magnets 2 are fixedly installed in the inner cavities of both the left and right arc-shaped blocks 1 and 101. Rubber blocks 3 are fixedly installed in the middle of the inner walls of both the left and right arc-shaped blocks 1 and 101. The upper and lower sides of the outer surface of the rubber blocks 3 are frosted, while the middle of the outer surface is smooth. The rubber blocks 3 are made of synthetic rubber. During use, the rubber blocks 3 increase the friction between the left and right arc-shaped blocks 1 and 101 and the outer surface of the scaffolding, thereby improving the stability of the scaffolding during fixing. A left strip block 4 is fixedly mounted on the front side of the left arc-shaped block 1. The left arc-shaped block 1 and the right arc-shaped block 101 are connected to the left strip block 4. The position and shape of the left and right arc blocks 1 and 101 are matched. The cross-section of the inner cavity after the left and right arc blocks 1 and 101 are combined is circular. Therefore, when in use, the left and right arc blocks 1 and 101 are rotated and fitted together, and the scaffolding is fixed by the left and right strip blocks 4 and 401 that are fitted together. A first circular hole 5 is opened in the middle of the left side of the left strip block 4, and a limiting hole 6 is opened on the rear side of the left side of the left strip block 4. A gasket 7 is detachably installed on the right side of the inner cavity of the first circular hole 5, and a nut 8 is detachably installed on the left side of the inner cavity of the first circular hole 5. A limiting block 9 is fixedly installed on the rear side of the left side of the nut 8. The depth of the inner cavity of the first circular hole 5 matches the length of the combined gasket 7 and nut 8, and the shape of the outer surface of the limiting block 9 matches the shape of the inner cavity of the limiting hole 6. Therefore, in use, after the nut 8 is installed into the inner cavity of the first round hole 5, the limiting block 9 extends into the inner cavity of the limiting hole 6 to fix the position of the nut 8 and prevent the nut 8 from easily rotating after being fixed. A right strip block 401 is fixedly installed on the front side of the right arc block 101. A second round hole 10 is opened in the middle of the right side of the right strip block 401. Through holes 11 are opened on the left side of the inner cavity of the second round hole 10 and the right side of the inner cavity of the first round hole 5. The through holes 11 penetrate the left side of the right strip block 401, the inner cavity of the second round hole 10, the right side of the left strip block 401, and the inner cavity of the first round hole 5. After the through holes 11 and the second round hole 10 are combined, the shape of the inner cavity matches the shape of the outer surface of the bolt 13. The length of the bolt 13 matches the length between the inner cavities of the first round hole 5 and the second round hole 10 after combination. In use, bolt 13 extends into the inner cavity of the second circular hole 10 and passes through the through hole 11 into the inner cavity of the first circular hole 5, thereby connecting the left strip block 4 and the right strip block 401. Multiple locking holes 12 are fixedly installed on the right side of the right strip block 401, evenly distributed around the second circular hole 10. The inner shape of the locking hole 12 matches the outer surface shape of the locking rod 18. Thus, in use, after the locking rod 18 extends into the inner cavity of the locking hole 12, bolt 13 is fixedly secured, preventing bolt 13 from rotating and loosening. Bolt 13 is detachably installed in the inner cavity of the second circular hole 10. A groove 14 is formed in the middle of the right side of bolt 13. A spring 15 is fixedly installed on the left side of the inner cavity of the groove 14. An extension block 16 is fixedly installed on the other side of the spring 15, and a swivel ring 17 is fixedly installed on the other side of the extension block 16.The extension block 16 and the swivel ring 17 are connected to the right side of the bolt 13 via the spring 15. The length of the extension block 16 within the cavity of the groove 14 is greater than the stretchable length of the spring 15, while the stretchable length of the spring 15 is less than the depth of the cavity of the groove 14. Therefore, during use, the right side of the extension block 16 will not move out of the cavity of the groove 14 due to the stretchable length of the spring 15 and the length of the extension block 16. Locking rods 18 are fixedly installed on both the upper and lower sides of the outer surface of the swivel ring 17. The depth of the cavity of the locking hole 12 is less than the stretchable length of the spring 15. Therefore, during use, pulling the swivel ring 17 to the right will move the locking rods 18 out of the locking hole 12 without the extension block 16 moving out of the cavity of the groove 14. At this time, the swivel ring 17 can drive the bolt 13 to rotate via the extension block 16. Inclined grooves 19 are provided at the bottom of the cavities of the first circular hole 5 and the second circular hole 10.

[0025] Working principle: During operation, the left arc-shaped block 1, right arc-shaped block 101, left strip block 4, and right strip block 401 are wrapped around the outer surface of the scaffold. Then, the washer 7 and nut 8 are inserted into the inner cavity of the first round hole 5 in sequence. The limiting hole 6 and limiting block 9 are used to prevent the nut 8 from rotating. Then, the bolt 13 is inserted from the second round hole 10 through the through hole 11 into the middle of the nut 8 in the inner cavity of the first round hole 5. At this time, rotating the swivel ring 17 causes the left side of the bolt 13 to rotate and connect with the nut 8. As the bolt 13 continues to rotate, the left side of the bolt 13 gradually connects with the nut 8. When the bolt 13 and nut 8 are rotated to the point where they can no longer be rotated, the swivel ring 17 is pulled to the right, causing the locking rod 18 to move and extend into the inner cavity of the locking hole 12. Then the swivel ring 17 is released. The locking rod 18 and the locking hole 12 are used to fix the swivel ring 17 to prevent it from rotating on its own, that is, to prevent the swivel ring 17 and the bolt 13 from rotating during use. At the same time, the rubber block 3 and the magnet 2 are used to increase the friction between the left arc block 1 and the right arc block 101 and the scaffold. Multiple structures are combined to improve the stability of the scaffold coupler during use.

[0026] When disassembly is required, simply pull the rotating ring 17 to the right to move the locking rod 18 out of the inner cavity of the locking hole 12. At this time, the rotating ring 17 can rotate to drive the bolt 13 to rotate until the bolt 13 separates from the nut 8. At this time, the left strip block 4 and the right strip block 401 can be separated, and the whole device can be quickly disassembled.

[0027] In summary, this easy-to-install scaffolding coupler has the advantages of quick installation and disassembly and improved stability after installation compared to similar devices.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
