[0001] This invention relates to the field of conduit assembly, specifically to an assembled conduit connection device and its usage method. Background Technology

[0002] Electrical conduits are typically pre-installed at the joints of building components and accessories, and connecting devices are needed to connect the electrical conduits.

[0003] Most existing conduit connection devices use clamps to connect and fix the conduit. They typically insert the connecting pipe into the conduit connection device and then use bolts or other structures to hold the connecting pipe in place, ensuring the stability of the connection between the connecting pipe and the conduit connection device. However, the bolts of this device are exposed to the air and are easily exposed to water, which can cause corrosion and affect the user's subsequent maintenance of the device. Summary of the Invention

[0004] The purpose of this invention is to provide an assembled conduit connection device and its usage method, to solve the problem mentioned in the background art that the bolts of the device are exposed to the air and easily come into contact with water, resulting in corrosion and affecting the user's subsequent maintenance of the device. To achieve the above objective, this invention provides the following technical solution: an assembled conduit connection device, including a fixed pipe, wherein two fastening mechanisms are fixedly connected to the side of the fixed pipe, one of which has a locking mechanism threadedly connected to its side, and one end of the locking mechanism abuts against the side of the fixed pipe;

[0005] The side of the fixed tube is provided with a through groove, the inner wall of the through groove is slidably connected to the side of the fastening mechanism, and both ends of the side of the fixed tube are fixedly connected with round tubes, and the side of the round tubes is hinged to the side of the fastening mechanism. Limit rods are fixedly connected to the opposite sides of the two round tubes.

[0006] Connecting pipes are slidably connected to both sides of the inner wall of the fixed pipe. A sliding groove is provided on the side of the connecting pipe, and the inner wall of the sliding groove is slidably connected to the inner wall of the limiting rod. A threaded groove is provided on the side of the connecting pipe, and a groove is provided on the side of the inner wall of the threaded groove. A connecting mechanism is threadedly connected to the inner wall of the threaded groove.

[0007] Preferably, the fastening mechanism includes a hinge plate, the side of which is hinged to the side of the circular tube. There are two hinge plates, and each of the two hinge plates has a rectangular groove on its side. A slide rod is slidably connected to the inner wall of each of the two rectangular grooves. An H-shaped rod is fixedly connected to the side of each of the two slide rods. A first spring telescopic rod is fixedly connected to the side of each H-shaped rod. The end of the first spring telescopic rod away from the H-shaped rod is fixedly connected to the side of the fixed tube.

[0008] A pressure plate is hinged to one end of each of the two hinged plates facing away from each other. The side of the pressure plate is slidably connected to the inner wall of the through groove, and one side of the pressure plate abuts against the side of the connecting pipe.

[0009] Preferably, the locking mechanism includes an abutting bolt, the side of which is threaded to the middle of the side of the H-shaped rod, one end of which abuts against the side of the fixing tube, and a handle is fixedly connected to the side of the abutting bolt.

[0010] Preferably, the connecting mechanism includes an internally threaded tube, the side of which is threaded to the inner wall of the threaded groove, a threaded rod is threaded to the inner wall of the internally threaded tube, a splined rod is movably inserted into the inner wall of the threaded rod, and a rotating rod is fixedly connected to the end of the splined rod away from the threaded rod. The rotating rod matches the groove and can be inserted into the groove.

[0011] The end of the threaded rod away from the spline rod abuts against an arc-shaped retaining plate. An arc-shaped pad matching the arc curvature of the arc-shaped retaining plate is bonded to the inner side of the arc-shaped retaining plate. A second spring telescopic rod is fixedly connected to the outer side of the arc-shaped retaining plate. The end of the second spring telescopic rod away from the arc-shaped retaining plate is fixedly connected to the inner wall of the round tube.

[0012] Preferably, the number of grooves is eight.

[0013] Preferably, the H-shaped rod has internal reinforcing ribs.

[0014] Preferably, the side of the rotating rod is covered with a rubber sleeve, and the side of the rubber sleeve abuts against the inner wall of the groove.

[0015] Preferably, the method of using the assembled conduit connection device includes the following steps:

[0016] S1: Insert the pipe fitting to be connected into the inside of the connecting pipe, between the two arc-shaped pads, then pull the rotating rod out of the groove and rotate the spline rod, causing the spline rod to rotate and drive the threaded rod to rotate. Under the limitation of the threaded rod by the internal threaded pipe, one end of the threaded rod moves to abut against the arc-shaped clamping plate. At this time, the arc-shaped clamping plate drives the arc-shaped pads inside it to clamp and fix the side of the pipe fitting. Then, insert the rotating rod into the inside of the groove to complete the connection between the connecting pipe and the pipe fitting.

[0017] S2: Then, by rotating the abutting bolt, the user causes one end of the abutting bolt to separate from the side of the fixed tube, ensuring that the user can compress the first spring telescopic rod. Then, by pressing the two H-shaped rods, the user drives the first spring telescopic rod to compress, causing the H-shaped rods to drive the two sliding rods to slide on the inner wall of the rectangular groove, causing the hinge plate to deflect. At this time, the pressure plate moves out from the inner wall of the through groove and separates from the side of the connecting tube. Then, the user pushes one end of the connecting tube towards the middle of the inner wall of the fixed tube, causing the spline rod and other structures to enter the interior of the fixed tube. The fixed tube reduces the possibility of the spline rod and other structures rusting due to contact with moisture.

[0018] S3: Then release the force applied to the H-shaped rod. Under the action of the first spring telescopic rod's restoring force, the pressure plate is reset and comes into contact with the side of the connecting tube. Then rotate the contact bolt, causing one end of the contact bolt to come into contact with the side of the fixed tube, and causing the H-shaped rod and the hinge plate to deflect. Under the action of the hinge plate's lever force, the contact force between the pressure plate and the side of the connecting tube is further strengthened, reducing the possibility of the connecting tube moving out of the fixed tube, thereby strengthening the device's protective effect on the spline rod and other structures.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In this invention, the pipe to be connected is inserted between two arc-shaped pads. By rotating the spline rod, under the limitation of the internal threaded pipe on the threaded rod, rotating the spline rod causes one end of the threaded rod to move and abut against the arc-shaped clamping plate. At this time, the arc-shaped clamping plate causes the arc-shaped pad inside it to clamp and fix the side of the pipe, thus completing the connection between the connecting pipe and the pipe fitting. The operation is simple and convenient.

[0021] In this invention, pressing the two H-shaped rods causes the hinge plate to deflect. At this time, the pressure plate moves out from the inner wall of the through groove and separates from the side of the connecting pipe. Then, the user pushes one end of the connecting pipe toward the middle of the inner wall of the fixed pipe, causing the spline rod and other structures to enter the interior of the fixed pipe. The fixed pipe reduces the possibility of corrosion of the spline rod and other structures due to contact with moisture.

[0022] In this invention, under the action of the first spring telescopic rod's restoring force, the pressure plate is reset and comes into contact with the side of the connecting tube. Then, the contact bolt is rotated, causing one end of the contact bolt to come into contact with the side of the fixed tube, and driving the H-shaped rod and the hinge plate to deflect. Under the action of the hinge plate's lever force, the contact force between the pressure plate and the side of the connecting tube is further strengthened, reducing the possibility of the connecting tube moving out of the fixed tube, thereby strengthening the device's protective effect on structures such as spline rods.
