Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and specifically to a quick pipe connection device. Background Technology

[0002] In building construction, welding is commonly used to connect two pipe sections. However, welding has several drawbacks: First, welding requires skilled operators who are familiar with the welding characteristics and parameters of different pipe materials. Improper operation can easily lead to defects such as incomplete welds and weld beads, directly affecting the connection quality. Second, welded pipes are non-removable. If pipe rerouting or replacement is necessary, the welded connection is difficult to disassemble and must be cut and re-welded, which can result in longer construction periods and increased costs.

[0003] While devices exist for connecting pipes to improve the convenience and detachability of pipe connections, these devices are often of fixed dimensions. A single device can only connect pipes of one diameter, cannot connect pipes of different diameters, and is difficult to use for connecting pipes of other diameters, thus limiting its application. Therefore, a pipe connection device that can adapt to connecting pipes of different diameters and is easy to install is needed. Utility Model Content

The connecting buckles are respectively connected to both ends of the main pipe body. A rotating sleeve and two movable sleeves are sleeved on the outer side of the main pipe body. The rotating sleeve is rotatably connected to the main pipe body, and the movable sleeves are slidably connected to the main pipe body. The inner walls of both ends of the rotating sleeve are respectively provided with internal threads, and the two internal threads have opposite directions of rotation. The outer walls of one end of each of the two movable sleeves are respectively provided with external threads that match the two internal threads. The two ends of the rotating sleeve are threadedly connected to the two movable sleeves through the cooperation of the internal threads and external threads. The main body has multiple through-holes at both ends, and the multiple through-holes are evenly arranged around the circumference of the main body. A baffle is slidably connected in the through-hole. The baffle is elastically connected to the main body by a spring. The side of the baffle near the movable sleeve has an inclined surface. The side of the inclined surface near the baffle is higher than the side near the movable sleeve. The sliding direction of the baffle and the extension and retraction direction of the spring are consistent with the radial direction of the main body. Preferably, the connecting buckle includes two clamps, each clamp having mounting holes at both ends. A connecting plate is symmetrically fixed on both sides of the end of the main body. Threaded rods are fixed on the upper and lower sides of the connecting plate, respectively. The threaded rods on the upper and lower sides of the connecting plate pass through the mounting holes of the two clamps. Locking nuts are threaded onto the threaded rods, and the locking nuts are located on the side of the clamp away from the connecting plate.

[0005] Preferably, a support ring plate is sleeved on the outer side of the end of the main body, the support ring plate is fixedly connected to the main body, there is a gap between the support ring plate and the main body, a limiting hole is opened on the support ring plate at the position corresponding to the baffle, the top of the baffle slides through the limiting hole and extends to the outside of the support ring plate, and a limiting plate is fixed on the top of the baffle. The spring is sleeved on the outside of the baffle, and the spring is located between the limiting plate and the support ring plate. One end of the spring is fixedly connected to the limiting plate, and the other end of the spring is fixedly connected to the support ring plate.

[0006] Preferably, the support ring plate is fixedly connected to the main body through multiple support plates, and the multiple support plates correspond to the positions and numbers of multiple baffles; The support plate is located on the side of the baffle away from the movable sleeve. The side of the support plate near the baffle is provided with a sliding groove. A slider is fixed on the side of the baffle near the support plate. The slider is slidably disposed in the sliding groove. The sliding groove is arranged radially along the main body.

[0007] Preferably, there are four baffles at each end of the main body.

[0017] Combined with appendix Figure 1 -Appendix Figure 3A quick pipe connection device includes a main pipe body 1 and two connecting buckles for connecting to the pipe body. The connecting buckles are respectively connected to both ends of the main pipe body 1. A rotating sleeve 2 and two movable sleeves 3 are sleeved on the outside of the main pipe body 1. The rotating sleeve 2 is rotatably connected to the main pipe body 1, and the movable sleeves 3 are slidably connected to the main pipe body 1. The inner walls of both ends of the rotating sleeve 2 are respectively provided with internal threads, and the two internal threads are rotated in opposite directions. The outer walls of one end of each of the two movable sleeves 3 are respectively provided with external threads that match the two internal threads. The two ends of the rotating sleeve 2 are threadedly connected to the two movable sleeves 3 through the cooperation of the internal threads and external threads. The main body 1 has multiple moving holes 13 at both ends, which are evenly arranged around the circumference of the main body 1. A baffle 4 is slidably connected inside the moving hole 13. The baffle 4 is elastically connected to the main body 1 by a spring. The baffle 4 has an inclined surface on the side near the moving sleeve 3. The side of the inclined surface near the baffle 4 is higher than the side near the moving sleeve 3. The sliding direction of the baffle 4 and the extension and retraction direction of the spring are consistent with the radial direction of the main body 1. The two ends of the main pipe body 1 are used to insert the pipes to be connected. After the pipes are inserted into the main pipe body 1, the baffle 4 can limit the pipes. A sealing ring is placed between the pipes and the baffle 4, and the sealing ring is clamped and fixed by the pipes and the baffle 4. The sealing ring can improve the airtightness of the pipe connection. When pipes of different diameters need to be connected, the rotating sleeve 2 is rotated. At this time, the moving sleeve 3 moves axially along the main pipe body 1 under the action of the internal and external threads. The two moving sleeves 3 move in opposite directions. When the moving sleeve 3 moves closer to the baffle 4, the moving sleeve 3 can press the baffle 4 downward by the inclined surface of the baffle 4. When the moving sleeve 3 moves away from the baffle 4, the baffle 4 can move upward under the action of the spring force. It can be realized that the length of the baffle 4 extending into the main pipe body 1 can be adjusted by adjusting the moving sleeve 3, thereby limiting the pipes of different diameters. When connecting pipes of different diameters, a sealing ring can be placed between the pipes and the baffle 4 to improve the airtightness. The outer diameter of the sealing ring is consistent with the inner diameter of the main pipe 1, and the inner diameter of the sealing ring is consistent with the inner diameter of the pipe to be connected.

[0018] When the movable sleeve 3 is not in contact with the inclined surface of the baffle 4, the spring is in its natural state. When the movable sleeve 3 presses against the baffle 4 through the inclined surface, the spring is compressed.

[0019] Specifically, the connecting buckle includes two clamps 8, each clamp having a mounting hole at both ends. A connecting plate 7 is symmetrically fixed on both sides of the end of the main body 1. Threaded rods 9 are fixed on the upper and lower sides of the connecting plate 7, respectively. The threaded rods 9 on the upper and lower sides of the connecting plate 7 pass through the mounting holes of the two clamps 8. A locking nut 10 is threaded onto the threaded rod 9, and the locking nut 10 is located on the side of the clamp 8 away from the connecting plate 7.

[0020] Two clamps 8 located at the same end are symmetrically distributed vertically. The clamps 8 can move up and down along the threaded rod 9 to adjust their position according to the pipe to be connected. By tightening the locking nut 10, the two clamps 8 clamp the pipe, thus fixing the pipe to the main pipe body 1. More specifically, the inner wall of the clamp 8 is a non-semi-circular arc segment, such as a semi-elliptical inner wall, so that it can clamp pipes of different diameters.

[0021] Specifically, a support ring plate 5 is sleeved on the outer side of the end of the main body 1. The support ring plate 5 is fixedly connected to the main body 1. There is a gap between the support ring plate 5 and the main body 1. A limiting hole is opened on the support ring plate 5 at a position corresponding to the baffle 4. The top end of the baffle 4 slides through the limiting hole and extends to the outside of the support ring plate 5. A limiting plate 41 is fixed on the top end of the baffle 4. The spring is sleeved on the outside of the baffle 4, and is located between the limiting plate 41 and the support ring plate 5. One end of the spring is fixedly connected to the limiting plate 41, and the other end of the spring is fixedly connected to the support ring plate 5. The support ring plate 5 provides a bearing portion for the baffle 4 to connect with the main body 1.

[0022] Specifically, the support ring plate 5 is fixedly connected to the main body 1 through multiple support plates 6, and the multiple support plates 6 correspond in position and number to the multiple baffles 4; The support plate 6 is located on the side of the baffle 4 away from the movable sleeve 3. A groove is provided on the side of the support plate 6 closest to the baffle 4. A slider 42 is fixed to the side of the baffle 4 closest to the support plate 6. The slider 42 is slidably disposed in the groove, which is radially arranged along the main tube 1. The cooperation between the groove and the slider 42 improves the stability of the baffle 4's movement.

[0023] More specifically, there are four baffles 4 at each end of the main body 1.

[0024] Specifically, the inner diameters at both ends of the main pipe 1 are larger than the inner diameter of the middle part of the main pipe 1. A baffle 11 is formed at the junction of the large and small inner diameters of the main pipe 1. The surface of the baffle 11 is flush with the side of the baffle 4 away from the movable sleeve 3. When connecting the pipe, the sealing ring is first placed inside the main pipe 1 so that one side of the sealing ring contacts and fits against the side of the baffle 4 and the surface of the baffle 11.

[0025] Specifically, a slide rail 12 is fixed to the outer wall of the main tube 1, and a sliding groove matching the slide rail 12 is provided on the inner wall of the movable sleeve 3. The movable sleeve 3 and the main tube 1 are slidably connected through the cooperation of the slide rail 12 and the sliding groove. More specifically, there are two slide rails 12 on the outer wall of each end of the main tube 1. The two slide rails 12 are symmetrically distributed, and the number and position of the sliding groove on each movable sleeve 3 correspond to the number and position of the slide rails 12 on the main tube 1 at the same end.
