Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical parts technology, specifically a tubular right-angle fastener. Background Technology
[0002] Couplers are commonly used connecting parts in construction engineering, used to fix components such as steel pipe scaffolding. They are mainly divided into right-angle couplers, swivel couplers, and butt couplers, and can be classified by material as cast iron or pressed steel plate couplers. They possess properties such as resistance to breakage, slippage, deformation, detachment, and rust, ensuring structural stability and safety. In construction and scaffolding erection, couplers play a crucial role, making component connections more secure and reliable. Tubular right-angle couplers are a type of connector used in the construction field, primarily for connecting two perpendicularly intersecting steel pipes. Existing tubular right-angle couplers typically require the installation of multiple steel pipes. When assembling and installing steel pipes using tubular right-angle couplers, nuts and bolts are used to press the pipe clamps together. However, because steel pipes vary in size, pressing the pipe clamps with nuts and bolts may not ensure a complete fit between the pipe clamp and the coupler base. This creates an angle between the nut and the pipe clamp, easily leading to detachment and affecting worker safety. Utility Model Content

Multiple first inlay grooves are opened on the front and rear surfaces of the fastener base, and multiple second inlay grooves are opened on the corresponding surfaces of the two pipe clamps. A first rubber tube is inlaid and connected inside the multiple first inlay grooves.
[0008] Preferably, the limiting structure further includes a rubber pad, which is fixedly sleeved on the upper outer surface of the limiting rod, and the rubber pad is in contact with the inner wall of the convex circular groove.

[0020] 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.
[0021] Please see Figure 1-4 This utility model provides a new technical solution: a tubular right-angle fastener, including a fastener base 1 and two pipe clamps 4, the two pipe clamps 4 being respectively hinged to the front and rear surfaces of the fastener base 1;
[0022] The limiting structure is set in the pipe clamp 4. The limiting structure includes a limiting rod 5 and a pull ring 6. A convex circular groove 7 is opened at the right end of the upper surface of the pipe clamp 4. The lower end of the convex circular groove 7 extends to the lower end of the interior of the pipe clamp 4. The limiting rod 5 is slidably installed inside the convex circular groove 7. The pull ring 6 is rotatably installed at the upper end of the limiting rod 5. Multiple first inlay grooves 8 are opened on the front and rear surfaces of the fastener base 1. Multiple second inlay grooves 9 are opened on the corresponding surfaces of the two pipe clamps 4. A first rubber tube 11 is inlaid and connected inside the multiple first inlay grooves 8.
[0023] Furthermore, the limiting structure also includes a rubber pad 10, which is fixedly sleeved on the upper outer surface of the limiting rod 5, and the rubber pad 10 is in contact with the inner wall of the convex circular groove 7.
[0024] Furthermore, the limiting rod 5 and pull ring 6 in the convex circular groove 7, together with the rubber pad 10, effectively limit the movement range of the two bolts 3, prevent the two 3 from shifting during use, increase the stability when fixing the steel pipe, and increase the friction between the fastener and the steel pipe by multiple 8 and multiple 9 as well as multiple 11 and multiple 12, further increasing the stability between the fastener and the steel pipe, thereby improving the safety of the workers.
[0025] Furthermore, there are two limiting structures in total, which are respectively located at the upper end of the front pipe clamp 4 and the right end of the rear pipe clamp 4.
[0026] Furthermore, each of the multiple second inlay grooves 9 has a second rubber tube 12 inlaid and connected inside.
[0027] Furthermore, mounting grooves 13 are provided on both the front and rear surfaces of the fastener base 1. The upper surface of the front mounting groove 13 is open, and the right end of the rear mounting groove 13 is open. Bolts 3 are rotatably installed inside both mounting grooves 13.
[0028] Furthermore, the right end of the front bolt 3 is threaded with a nut 2, and the rear end of the rear bolt 3 is threaded with the same nut 2.
[0029] Furthermore, when using this right-angle fastener, it can be placed on the outer surface of the steel pipe to be fixed. Then, first fasten one 4 to fix one steel pipe to the right-angle fastener. Rotate the corresponding 2, and 2 will rotate on the corresponding 3 and move closer to the corresponding 4, so that 2 and 3 fix the corresponding 4 and 1. The friction between the fastener and the steel pipe is increased by multiple 8 and multiple 9, as well as multiple 11 and multiple 12, which increases the stability between the fastener and the steel pipe. Then, place another steel pipe between another 4 and 1 and repeat the above operation to fix the other steel pipe. After fixing, the two 5 can be picked up by two 6, aligned with the corresponding 7, and pushed in, so that the two 5 further limit the corresponding 7, preventing the two 3 from shifting during use and affecting the safety of the staff. The two 10 can fix the two 5 to a certain extent, so that the 5 can stay inside the 7. When the two 3 squeeze the two 5, the 5 squeezes the inner wall of the 7, so that the two 5 are not easy to fall off. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
