Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering conduits, specifically to a quick-connect assembly for low-voltage engineering conduits. Background Technology

[0002] Low-voltage electrical conduits are pipes used to protect and lay wires and cables in low-voltage electrical engineering. Common types include PVC pipes, KBG pipes, JDG pipes, and SC pipes. Low-voltage systems are usually used for signal processing. During the construction of low-voltage systems, they are easily affected by factors such as corrosion, friction, and wear, which can lead to problems such as short circuits and leakage. Therefore, conduits are usually used for connection and protection.

[0003] Existing low-voltage electrical wiring conduits are connected using either heat fusion or threaded connections. Heat fusion connections require heating and fusing the conduits with heat fusion equipment, which is a complex process requiring specialized skills and equipment. Furthermore, the conduits need to cool down after fabrication before they can be used, increasing the construction cycle. Heat fusion and threaded connections are also difficult to disassemble or replace when the conduits need to be replaced, requiring cutting or damaging the original connections, which increases maintenance costs and difficulty.

[0004] Therefore, it is necessary to invent a quick-connect assembly for low-voltage electrical conduits to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-connect assembly for low-voltage electrical conduits. This assembly connects a first connector at one end of the main low-voltage conduit to a second connector on the other side of the secondary low-voltage conduit. Once the first connector is inserted into the bottom of the second connector, rotating the first connector causes the connecting pipe to rotate. Then, rotating the handle causes the protruding part below the handle to press against the handle inside the handle, thus achieving a quick connection. This addresses the problem mentioned in the background art where existing low-voltage electrical conduits are connected using either heat fusion or threaded connections. Heat fusion connections require heating and fusing the conduit with heat fusion equipment, a complex process requiring specialized skills and equipment. Furthermore, cooling time is required after fabrication, increasing the construction cycle. Heat fusion and threaded connections are difficult to disassemble or replace, requiring cutting or damaging the original connection, increasing maintenance costs and difficulty.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect assembly for low-voltage electrical conduit, comprising a main low-voltage electrical conduit; The first connector is fixed to one end of the main low-voltage conduit for connecting the main low-voltage conduit. A connecting pipe is fixedly connected to the inner side of the first connector, and a groove is formed on the outer surface of the connecting pipe. A second connector is provided on one side of the first connector. Movable grooves are formed on the upper and lower inner sides of the second connector. A connecting rod is rotatably connected inside the movable groove. A handle is fixedly connected to the outside of the connecting rod. A protrusion is fixedly connected to the front end of the handle. A secondary low-voltage conduit is fixedly connected to the rear side of the second connector.

[0007] Preferably, the outer two sides of the first connector are fixedly connected with buckles, and the buckles are U-shaped.

[0008] Preferably, the outer front end of the connecting tube is provided with sliding grooves on both sides, and the sliding grooves are slidably connected to the protrusions outside the handle.

[0009] Preferably, the second connector has a sealing ring inside, which is embedded in the front end of the secondary low-voltage conduit.

[0010] Preferably, the second connector has two sets of limiting blocks on its external fixed connection, and the buckle on the outside of the first connector is movably engaged with the limiting blocks.

[0011] Preferably, the handle is rotatably connected to the second connector, and the outer side of the handle abuts against the inner groove of the connecting tube.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: By setting up the main low-voltage conduit, the first connector, the connecting rod, the handle, and the protrusion, the first connector at one end of the main low-voltage conduit is connected to the second connector on the other side of the secondary low-voltage conduit. When the first connector is inserted into the bottom of the second connector, the first connector is rotated to drive the connecting pipe to rotate. Then, by rotating the handle, the protruding part below the handle is pressed against the groove on the outside of the connecting pipe, thereby achieving a quick connection. With the arrangement of the first connector, buckle, slide groove, second connector, limiting block and handle, when the first connector and the second connector are connected, the buckle is rotated outside the limiting block outside the second connector by rotating the first connector, thereby strengthening the connection between the first connector and the second connector. At the same time, the slide groove outside the connecting tube also rotates with the first connector, allowing the slide groove to rotate to another direction, so that the handle can better abut against the groove outside the connecting tube.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-5 The present invention is a quick-connect assembly for low-voltage electrical conduit, comprising a main low-voltage electrical conduit 1; The first connector 2 is fixed to one end of the main low-voltage conduit 1 for connecting the main low-voltage conduit 1. A connecting pipe 4 is fixedly connected to the inner side of the first connector 2. A groove 5 is opened on the outer surface of the connecting pipe 4. A second connector 7 is provided on one side of the first connector 2. Movable grooves 10 are opened on the upper and lower inner sides of the second connector 7. A connecting rod 11 is rotatably connected inside the movable groove 10. A handle 12 is fixedly connected to the outside of the connecting rod 11. A protrusion 13 is fixedly connected to the front end of the handle 12. A secondary low-voltage conduit 14 is fixedly connected to the rear side of the second connector 7. By connecting the first connector 2 at one end of the main low-voltage conduit 1 into the second connector 7 on the other side of the secondary low-voltage conduit 14, when the first connector 2 extends into the bottom of the second connector 7, rotating the first connector 2 will drive the connecting pipe 4 to rotate. Then, by rotating the handle 12, the protruding part below the handle 12 will press against the groove 5 on the outside of the connecting pipe 4, thereby realizing a quick connection.

[0018] like Figure 1 , Figure 2 and Figure 5 As shown, buckles 3 are fixedly connected to the outer sides of the first connector 2. The buckles 3 are U-shaped. The buckles 3 on the outer side of the first connector 2 can be fitted onto the upper limit block 9 outside the second connector 7.

[0019] like Figure 2 , Figure 3 and Figure 4 As shown, the outer front end of the connecting tube 4 has grooves 6 on both sides. The grooves 6 are slidably connected to the protrusions 13 on the outside of the handle 12. When the connecting tube 4 is inserted into the inside of the second connecting member 7, the handle 12 is in a vertical state. At this time, the grooves 6 on the outside of the connecting tube 4 are aligned with the protrusions 13 on the outside of the handle 12 and slide into the inside of the second connecting member 7. When the front end of the connecting tube 4 abuts against the inside of the second connecting member 7, and then the connecting tube 4 is rotated, the connecting tube 4 can be limited to the inside of the second connecting member 7.

[0020] like Figure 2 and Figure 3 As shown, the second connector 7 has a sealing ring 8 inside. The sealing ring 8 is embedded in the front end of the secondary low-voltage conduit 14. The sealing ring 8 enhances the sealing between the first connector 2 and the second connector 7, preventing water and dust from seeping into the main low-voltage conduit 1 and the secondary low-voltage conduit 14 and causing a low-voltage short circuit.

[0021] like Figure 5 As shown, the second connector 7 is externally fixedly connected with two sets of limiting blocks 9. The buckle 3 on the outside of the first connector 2 is movably engaged with the limiting block 9. When the first connector 2 and the connecting tube 4 are inserted into the second connector 7 to the bottom, rotating the first connector 2 causes the external buckle 3 to move on the limiting block 9 outside the second connector 7, so that the limiting block 9 can limit the buckle 3 and the first connector 2, thereby strengthening the connection between the first connector 2 and the second connector 7.

[0022] like Figure 3 and Figure 4 As shown, the handle 12 is rotatably connected to the second connector 7. The outer side of the handle 12 abuts against the groove 5 inside the connecting tube 4. When the connecting tube 4 and the inner part of the second connector 7 rotate together, the handle 12 is pressed and flipped so that the protruding part below the handle 12 abuts against the groove 5 outside the connecting tube 4, so that the handle 12 is pressed outside the connecting tube 4, thereby strengthening the firmness of the connecting tube 4 inside the second connector 7.

[0023] The working principle of this utility model is as follows: When it is necessary to quickly connect the main low-voltage conduit 1 and the auxiliary low-voltage conduit 14, the first connector 2 at one end of the main low-voltage conduit 1 is inserted into the second connector 7 on the other side of the auxiliary low-voltage conduit 14. The sliding groove 6 on the outside of the connecting tube 4 is aligned with the protrusion 13 on the outside of the handle 12 and slides into the interior of the second connector 7. When the front end of the connecting tube 4 abuts against the inside of the second connector 7, rotating the connecting tube 4 causes the external sliding groove 6 to rotate and move away from the position of the protrusion 13 below the handle 12. At the same time, rotating the first connector 2 drives... The external buckle 3 moves in the direction of the limiting block 9 outside the second connector 7, so that the limiting block 9 can limit the buckle 3 and the first connector 2, thereby strengthening the firmness between the first connector 2 and the second connector 7. Next, press the handle 12 inside the movable groove 10 on the upper and lower sides of the second connector 7 to flip it over, so that the protruding part below the handle 12 presses against the groove 5 outside the connecting tube 4, so that the handle 12 is pressed outside the connecting tube 4, strengthening the firmness of the connecting tube 4 inside the second connector 7. In this way, the use process of the quick-connect assembly of the low-voltage engineering conduit is completed.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
