Description

Technical Field

[0001] This utility model relates to the field of steel pipe connection technology, and in particular to a quick connection structure for steel pipes. Background Technology

[0002] In engineering applications, it is often necessary to connect two steel pipes together. Most existing common connection methods involve welding or connecting steel pipe sleeves with bolts.

[0003] However, welding makes the steel pipe impossible to disassemble. While connecting the steel pipe with a sleeve and bolts allows for disassembly, the sleeve has multiple bolts on its surface, requiring a large number of bolts to be tightened during connection and disassembly, resulting in significant workload and time consumption. To address these shortcomings, we propose a quick-connect structure for steel pipes. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a quick connection structure for steel pipes.

[0005] To address the problems existing in the prior art, this utility model adopts the following technical solution: a quick-connect structure for steel pipes, comprising:

[0006] A docking structure, the docking structure including a sleeve, a lateral connecting cylinder, and a lateral connecting assembly disposed on the surface of the sleeve for integral assembly with the lateral connecting cylinder;

[0007] The locking structure consists of clamping components respectively disposed inside the sleeve and the lateral connecting cylinder, and pushing components respectively disposed on the surfaces of the sleeve and the lateral connecting cylinder;

[0008] The clamping assembly includes a through hole formed on the surface of the sleeve and the side connecting cylinder, a guide rod slidably mounted on the inner wall of the through hole, and a clamping plate fixedly mounted on one end of the guide rod;

[0009] The actuating assembly includes nuts threaded onto the surfaces of the sleeve and the lateral connecting cylinder, a guide groove formed on the inner wall of the nut, a roller seat fixedly mounted on one end of the guide rod, and a guide ball rollingly fitted on the inner wall of the roller seat.

[0010] Preferably, the lateral connection assembly includes an assembly cylinder fixedly mounted on the surface of the sleeve, and an externally threaded cylinder fixedly mounted on one end of the lateral connection cylinder, wherein the inner wall of the assembly cylinder is provided with an internally threaded hole that is compatible with the externally threaded cylinder.

[0011] Preferably, the interior of the assembly cylinder is in communication with the interior of the sleeve.

[0012] Preferably, there are multiple through holes arranged in a circumferential array on the surfaces of the sleeve and the lateral connecting cylinder.

[0013] Preferably, the guide groove is cone-shaped.

[0014] Preferably, retaining rings are fixedly installed on the surfaces of both the sleeve and the lateral connecting cylinder.

[0015] Preferably, a rubber anti-slip pad is provided on the side of the clamp away from the guide rod.

[0016] Preferably, the guide ball is located inside the guide groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By setting a locking structure, the two steel pipes to be connected are inserted into the sleeve respectively, and then the nuts are tightened. This drives the guide groove to contact the guide ball. After the guide ball is subjected to force, it drives multiple clamping plates to move closer to the steel pipes to be connected, thereby clamping and fixing the steel pipes. Compared with the existing technology, this device does not require welding and breaks the traditional requirement of tightening multiple bolts to fix the steel pipes in the steel pipe connecting sleeve. This improves the connection efficiency of steel pipes and reduces the workload.

[0019] 2. By setting up a lateral connection component, when it is necessary to connect a steel pipe to the surface of the sleeve, the external threaded cylinder can be screwed into the internal threaded hole on the inner wall of the assembly cylinder, thereby fixing the connecting cylinder to the surface of the sleeve. The locking structure on the surface of the assembly cylinder can then be used to fix the steel pipe inside the connecting cylinder. This allows for quick fixing of the steel pipe to the surface of the sleeve according to construction needs, thus improving the practicality of the device. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a quick connection structure for steel pipes, including: a butt joint structure and a locking structure.

[0029] The docking structure includes a sleeve 10, a lateral connecting cylinder 11, and a lateral connecting assembly disposed on the surface of the sleeve 10 for assembly with the lateral connecting cylinder 11. The lateral connecting assembly includes an assembly cylinder 40 fixedly mounted on the surface of the sleeve 10, and an externally threaded cylinder 41 fixedly mounted on one end of the lateral connecting cylinder 11.

[0030] The locking structure consists of clamping components respectively disposed inside the sleeve 10 and the lateral connecting cylinder 11, and pushing components respectively disposed on the surfaces of the sleeve 10 and the lateral connecting cylinder 11.

[0031] The clamping assembly includes through holes formed on the surfaces of the sleeve 10 and the lateral connecting cylinder 11, a guide rod 20 slidably mounted on the inner wall of the through holes, and a clamping plate 21 fixedly mounted on one end of the guide rod 20. There are multiple through holes arranged in a circumferential array on the surfaces of the sleeve 10 and the lateral connecting cylinder 11. A rubber anti-slip pad is provided on the side of the clamping plate 21 away from the guide rod 20.

[0032] The driving assembly includes a nut 30 threadedly connected to the surfaces of the sleeve 10 and the side connecting cylinder 11, a guide groove 31 formed on the inner wall of the nut 30, the guide groove 31 being conical in shape, a roller seat 32 fixedly installed at one end of the guide rod 20, and a guide ball 33 rollingly engaged with the inner wall of the roller seat 32. The guide ball 33 is located inside the guide groove 31. Tightening the nut 30 can drive the nut 30 to approach the guide ball 33. At this time, the guide groove 31 will contact the guide ball 33. As the smallest inner annular surface of the guide groove 31 gradually approaches the guide ball 33, the guide ball 33 is subjected to force, which can drive multiple guide rods 20 and clamping plates 21 to approach each other.

[0033] Both the sleeve 10 and the side connecting sleeve 11 are fixedly installed with retaining rings 50. When the nut 30 is tightened, the inner wall of the nut 30 will contact the retaining ring 50, thereby preventing the nut 30 from moving excessively.

[0034] Insert the two steel pipes to be connected into the sleeve 10 respectively, and then tighten the nut 30. This will cause the guide groove 31 to contact the guide ball 33. After the guide ball 33 is subjected to force, it will cause multiple clamping plates 21 to move closer to the steel pipes to be connected. This will clamp and fix the steel pipes in the sleeve 10. When the nut 30 is loosened, the guide groove 31 will move away from the guide ball 33, so that the steel pipes can be quickly pulled out of the sleeve 10.

[0035] Compared with existing technologies, this device requires no welding and breaks away from the traditional method of using multiple bolts to fix steel pipes in place, thereby improving the efficiency of steel pipe connection and reducing workload.

[0036] The interior of the assembly cylinder 40 is interconnected with the interior of the sleeve 10, and the inner wall of the assembly cylinder 40 is provided with an internal thread hole that matches the external thread cylinder 41. After the external thread cylinder 41 is screwed into the internal thread hole in the assembly cylinder 40, the lateral connecting cylinder 11 can be fixed on the surface of the sleeve 10. When it is necessary to connect a steel pipe to the surface of the sleeve 10, the external thread cylinder 41 can be screwed into the internal thread hole in the inner wall of the assembly cylinder 40, thereby fixing the connecting cylinder 11 to the surface of the sleeve 10. The locking structure on the surface of the connecting cylinder 11 can be used to fix the steel pipe inside the connecting cylinder 11, thereby allowing the steel pipe to be quickly fixed on the surface of the sleeve 10 according to construction needs, which improves the practicality of the device.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
