Description

Technical Field

[0001] The present application relates to the technical field of lighting engineering, and in particular to a quick-connect pipe sleeve for lighting engineering pipelines. Background Art

[0002] In lighting projects, protecting wires from mechanical damage through a rational pipeline layout can significantly extend their service life. Common pipeline connection methods during construction include threaded connections, fusion, bonding, welding, ferrules, and clamps. While these connection methods technically ensure pipeline stability and safety, they often require the use of multiple tools, resulting in a cumbersome installation process and relatively low efficiency. Furthermore, the choice of connection method requires careful consideration of the pipeline's alignment and direction, increasing the complexity of installation and maintenance. Utility Model Content

[0003] In order to solve the problem that common pipeline connection methods include threaded connection, fusion, bonding, welding, ferrule type and clamp type, etc., which usually require the use of multiple tools to operate during actual installation, resulting in cumbersome installation process and relatively low work efficiency, the present application provides a quick-connect pipe sleeve for pipelines in lighting projects.

[0004] The present application provides a quick-connect pipe sleeve for lighting engineering pipelines using the following technical solutions:

[0005] A quick-connect pipe sleeve for pipelines used in lighting projects includes a sleeve, which includes a flexible tube. Positioning components are provided at both ends of the flexible tube. The positioning components include several wedge blocks distributed circumferentially along the flexible tube. Pressing tubes are also provided at both ends of the flexible tube. The pressing tubes include extrusion rings that are compatible with the wedge blocks, and the extrusion rings are detachably connected to the flexible tube.

[0006] Preferably, double-cone joints are provided on the inner sides of both ends of the flexible tube.

[0007] Preferably, a plurality of connecting ropes are provided between two adjacent wedge-shaped blocks.

[0008] Preferably, the extrusion ring is movable along the axial direction of the flexible pipe, and is used to squeeze the wedge block to fix the pipeline.

[0009] In summary, this application has the following beneficial technical effects:

[0010] By using the casing, the pressing tube and the positioning assembly in combination, the wedge block is squeezed by the extrusion ring, and the position of the extrusion ring relative to the wedge block is adjusted to adapt to pipelines of different sizes. At the same time, the variable diameter double-conical joint can be connected to the ports of pipelines of different sizes. It is also possible to choose whether to bend the flexible tube according to the direction of the pipeline, and the application range is wide. Compared with the existing technology, it has the effects of simple operation and wide application range. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following is combined with Figure 1-3 This application is described in further detail.

[0016] The embodiment of the present application discloses a quick-connect pipe sleeve for lighting engineering pipelines. Figure 1-3 A quick-connect sleeve for lighting pipelines includes a sleeve 1, which includes a bendable flexible tube 101. Flexible tube 101 can be made of either a corrugated tube or a soft tube, depending on the application. Each end of flexible tube 101 is fitted with a compression ring 2, which includes a removable extrusion ring 202 that is attached to the end of flexible tube 101. The threaded ring 201 can be connected to flexible tube 101 using either bolts or threads, depending on the application. For example, threaded ends 102 are fixedly mounted on each end of flexible tube 101, and extrusion ring 202 is fitted with a threaded ring 201 that matches threaded ends 102.

[0017] Reference Figure 3 A double-cone joint 103 is fixedly installed inside the flexible tube 101. A flexible pad is installed on the side away from each other of the two double-cone joints 103. When the pipeline port and the double-cone joint 103 are docked, the gap between the double-cone joint 103 and the pipeline port can be filled to ensure the sealing of the connection.

[0018] Reference Figure 2The positioning assembly 3 is mounted inside the extrusion ring 202. This assembly comprises several wedges 301 distributed circumferentially around the bi-conical connector 103. Connecting ropes 302, made of elastic material, are installed between adjacent wedges 301. Flexible pads are installed inside the wedges 301 to increase friction between them and the pipeline port. Positioning assembly 3 is placed over the outside of the pipeline port. Tightening the threaded ring 201 brings the extrusion ring 202 closer to the bi-conical connector 103, squeezing the wedges 301 and securing pipelines of varying sizes.

[0019] The implementation principle of a quick-connect pipe sleeve for lighting engineering pipelines in the embodiment of the present application is as follows:

[0020] The bending angle and direction of the flexible tube 101 can be adjusted as needed. Due to the bendable nature of the flexible tube 101 , it can flexibly adapt to different installation positions and spaces.

[0021] First, put the pressure tube 2 and the positioning assembly 3 on the outside of the pipeline port in sequence, and ensure that the wedge block 301 fits tightly against the pipeline surface. Then, the pipeline port is abutted against the double-tapered joint 103, and the threaded ends 102 at both ends of the flexible tube are docked with the threaded ring 201 on the pressure tube 2. By tightening the threaded ring 201, the extrusion ring 202 is close to the double-tapered joint 103, and pressure is applied to the wedge block 301 to prevent the pipeline port from sliding. Then, the pipeline port is firmly abutted against the double-tapered joint 103. In order to prevent the pipeline port and the double-tapered joint 103 from loosening during the previous tightening. Finally, tighten the threaded ring 201 to ensure that the wedge block can firmly fix the pipeline.
