Description

Technical Field

[0001] This invention relates to the field of pipe connection technology, and in particular to a suspended pipe connection device. Background Technology

[0002] Pipelines are indispensable in modern life and production, commonly used for transporting liquids and gases. They are primarily used in various installations in fields such as water supply and drainage, heating and gas supply, agricultural irrigation, and water conservancy projects. Due to structural limitations of some applications, pipelines are sometimes installed in a suspended manner. Since suspended pipelines are generally segmented, multiple pipes of different diameters need to be connected together using connectors when transporting liquids or gases over long distances. Current pipeline connectors cannot adjust their length according to the distance between two pipes, nor can they handle pipe misalignment, and their installation methods are relatively complex.

[0003] Therefore, there is an urgent need to invent a suspended pipe connection device that can adjust its length according to the pipe spacing, adjust its angle to deal with pipe misalignment, and has a relatively simple installation method. Summary of the Invention

[0004] To address the above problems, this invention proposes a suspended pipe connection device, the technical solution of which is as follows:

[0005] A suspended pipe connection device includes a pipe locking mechanism, an angle adjustment mechanism, and an installation distance adjustment mechanism. The pipe locking mechanism comprises two sets, each set corresponding to one pipe, and is used to lock and fix pipes of different diameters. The angle adjustment mechanism comprises two symmetrical sets, each set corresponding to one set of pipe locking mechanisms. Each pipe locking mechanism is installed inside its corresponding angle adjustment mechanism and can adjust its own orientation angle within the angle adjustment mechanism, which then fixes the adjusted pipe locking mechanism. The installation distance adjustment mechanism is installed between the two sets of angle adjustment mechanisms to adjust the distance between the two sets, thereby accommodating the distance between the two pipes.

[0006] Furthermore, the pipe locking mechanism includes a ball-head connecting pipe, a moving device, a moving locking block, a sliding rod, two return springs, one sealing ring, and one gear and rack; the tail end of the ball-head connecting pipe is an opening that gradually narrows from the outside to the inside, and the front end is shaped like a frustum; the tail end of the ball-head connecting pipe is connected to the corresponding pipe; the sealing ring is coaxially disposed inside the tail end of the ball-head connecting pipe; several moving locking blocks are provided and are evenly distributed in a circle around the axis of the ball-head connecting pipe at the tail end of the ball-head connecting pipe;

[0007] Each movable locking block has a ramp corresponding to the tail end of the ball-head connecting pipe. A rack is slidably mounted on the ramp surface, and a gear is rotatably mounted on it. A rack is parallel to rack one at the tail end of the gear on the ball-head connecting pipe. The gear meshes with rack one and rack two simultaneously. The bottom of the ramp is used to push the sealing ring one. The bottom of each movable locking block has an arc-shaped surface. The arc-shaped surfaces of all movable locking blocks work together to clamp the corresponding pipe. A connecting block is fixedly mounted at the top of the ramp of each movable locking block. Each movable locking block corresponds to a sliding rod.

[0008] The sliding rod is fixedly connected to a slider at its tail end. The slider is slidably mounted on the connecting block of the corresponding movable locking block along the radial direction of the corresponding pipe, and is connected to the corresponding connecting block through a return spring. The sliding rod is parallel to the pipe and slidably mounted on the ball joint connecting pipe. The moving device is used to drive the sliding rod to slide on the ball joint connecting pipe.

[0009] Furthermore, the moving device includes a worm gear, a worm, and a return spring; the worm gear is coaxially and rotatably mounted on the outer wall of the ball joint connecting pipe, and the worm is rotatably mounted on the ball joint connecting pipe and meshes with the worm gear; the front end of the sliding rod is connected to the ball joint connecting pipe through the return spring; several limiting plates are fixedly mounted on the worm gear, each sliding rod corresponds to one limiting plate, and a protrusion is fixedly mounted on the sliding rod, with the limiting plate contacting the protrusion; when the worm gear rotates and drives the limiting plate to move, the limiting plate drives the protrusion to move, thereby driving the sliding rod to slide.

[0010] Furthermore, a knob is coaxially fixedly mounted on one end of the worm gear.

[0011] Furthermore, the angle adjustment mechanism includes a spherical sleeve, a rotating device, a rotating limiting ring, and a fixing block; the frustum-shaped front end of the ball-head connecting tube is movably installed inside the spherical sleeve; the rotating limiting ring is coaxially rotatably installed on the spherical sleeve; several fixing blocks are provided, and are evenly distributed in a circle around the axis of the rotating limiting ring on the spherical sleeve, with each fixing block sliding radially on the spherical sleeve; the inner surfaces of all fixing blocks work together to fix the front end of the ball-head connecting tube; each fixing block has a limiting slide rod at both its left and right ends, and the rotating limiting ring has a limiting slide groove that gradually approaches the axis corresponding to the limiting slide rod, with the limiting slide rod slidingly installed in the limiting slide groove; the rotating device drives the rotating limiting ring to rotate, causing the limiting slide rod to slide in the limiting slide groove, thereby driving the fixing block to slide radially.

[0012] Furthermore, the rotating device includes a second worm gear and a second worm; the second worm gear is coaxially and fixedly connected to the rotation limiting ring and rotatably mounted on the spherical sleeve, and the second worm is rotatably mounted on the spherical sleeve and meshes with the second worm gear.

[0013] Furthermore, a knob is coaxially fixedly mounted on one end of the worm gear two.

[0014] Furthermore, the installation distance adjustment mechanism includes a movable sleeve, an inner cylinder, and a second sealing ring; the inner cylinder is slidably installed inside the movable sleeve, and the inner wall of the movable sleeve and the outer wall of the inner cylinder form a closed annular space, and the second sealing ring is movably installed in this annular space; the movable sleeve and the inner cylinder are respectively fixedly installed on two spherical sleeves and communicate with the corresponding spherical sleeves.

[0015] Because the present invention adopts the above-described technical solution, the present invention has the following advantages:

[0016] 1. The pipe locking mechanism of the present invention can lock and fix pipes of different diameters, the angle adjustment mechanism can adjust the orientation angle of the pipe locking mechanism, and the installation distance adjustment mechanism can adjust the distance between the two angle adjustment mechanisms. There is no need to adjust the pipe position; simply adjusting the angle adjustment mechanism and the installation distance adjustment mechanism can accommodate two misaligned pipes.

[0017] 2. The present invention has a simple structure, is easy to maintain, and is easy to install, making it easy to learn and with a low learning cost. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of the present invention; however, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention. Example:

[0040] This embodiment is used to connect two suspended pipes of different diameters;

[0041] like Figure 1 As shown, a suspended pipe connection device includes a pipe locking mechanism 1, an angle adjustment mechanism 2, and an installation distance adjustment mechanism 3; the pipe locking mechanism 1 is provided in two sets, one set of pipe locking mechanism 1 fixes and locks a pipe 4, and each set of pipe locking mechanism 1 corresponds to a set of angle adjustment mechanism 2; the pipe locking mechanism 1 is installed inside the corresponding angle adjustment mechanism 2, and the installation distance adjustment mechanism 3 is installed between the two sets of angle adjustment mechanisms 2;

[0042] like Figure 2-7 As shown, the pipe locking mechanism 1 includes a ball-head connecting pipe 101, a worm gear 102, a worm 103, a movable locking block 104, a return spring 105, a sliding rod 106, a second return spring 107, a sealing ring 108, a gear 109, and a rack 110. The tail end of the ball-head connecting pipe 101 is a frustum-shaped opening that gradually narrows from the outside to the inside, and the front end is shaped like a frustum. The tail end of the ball-head connecting pipe 101 is connected to the corresponding pipe 4. There are 8 movable locking blocks 104, which are evenly distributed and slidably arranged in a circle around the axis of the ball-head connecting pipe 101 at the tail end of the ball-head connecting pipe 101.

[0043] Each movable locking block 104 has a ramp corresponding to the tail end of the ball-head connecting pipe 101. A rack 110 is slidably installed on the ramp surface, and a gear 109 is rotatably installed. A rack 2 is provided on the ball-head connecting pipe 101 at the tail end of the gear 109, parallel to the rack 110. The gear 109 meshes with both the rack 110 and the rack 2. The bottom end of the movable locking block 104 has an arc-shaped surface. The arc-shaped surfaces of all movable locking blocks 104 work together to clamp the corresponding pipe 4. A connecting block is fixed at the top of the ramp of the movable locking block 104. Each connecting block has two radial grooves parallel to the radius of the pipe 4. Each movable locking block 104 corresponds to a sliding rod 106.

[0044] The sliding rod 106 has two support rods, which are parallel to each other and fixedly connected by a connecting rod. The two support rods of the sliding rod 106 are parallel to the pipe 4 and slidably installed on the ball head connecting pipe 101. A slider 1061 is fixedly connected to the tail end of each support leg. The slider 1061 is slidably installed on the radial groove of the connecting block of the corresponding moving locking block 104, and is connected to the corresponding connecting block through the second return spring 107, which is a compression spring.

[0045] The sealing ring 108 is coaxially set inside the tail end of the ball head connecting pipe 101. Before installing the pipe 4, the position of the sealing ring 108 is manually adjusted. Moving the bottom of the slope of the locking block 104 can push the sealing ring 108.

[0046] Worm gear 102 is coaxially mounted on the outer wall of ball joint connecting tube 101. Worm 103 is rotatably mounted on ball joint connecting tube 101 and meshes with worm gear 102. A knob 1031 is coaxially fixedly mounted on one end of worm 103. The front end of sliding rod 106 is connected to ball joint connecting tube 101 through return spring 105, which is a compression spring. Each sliding rod 106 corresponds to a limiting plate 1021. A protrusion is fixedly mounted on the sliding rod 106. The limiting plate 1021 is a right-angled triangular plate. One right-angled side of the limiting plate 1021 is fixedly mounted on worm gear 102 and the hypotenuse contacts the protrusion.

[0047] The operator first adjusts the position of the sealing ring 108, inserts the pipe 4 between the movable locking blocks 104, and connects it to the ball joint connecting pipe 101. The sealing ring 108 is then fitted onto the pipe 4. The operator rotates the knob 1031, causing the worm gear 103 to rotate. The rotation of the worm gear 103 causes the worm wheel 102 to rotate, which in turn causes the limiting plate 1021 to move. The inclined side of the limiting plate 1021 abuts against the protrusion. During the movement of the limiting plate 1021, the movement of the inclined side causes the protrusion to move towards the front end of the ball joint connecting pipe 101, thereby causing the sliding rod 106 to slide towards the front end of the ball joint connecting pipe 101, and the return spring 105 is compressed. Simultaneously... At this time, the slider 1061 at the tail end of the sliding rod 106 moves inward with the sliding rod 106, and drives the movable locking block 104 to move along the tail end of the ball joint connecting pipe 101 into the ball joint connecting pipe 101. At this time, the second reset spring 107 is compressed, and the gear 109 moves with the movable locking block 104. Since the gear 109 meshes with the second rack, the second rack drives the gear 109 to rotate. The rotation of the gear 109 drives the first rack 110 to move inward on the slope surface of the movable locking block 104, and pushes the first sealing ring 108 to move inward. Until the pipe 4 is locked and fixed by the movable locking block 104, the first sealing ring 108 ensures good sealing between the pipe 4 and the ball joint connecting pipe 101.

[0048] When pipe 4 needs to be disassembled for secondary use of pipe locking mechanism 1, the operator rotates knob 1031 in the reverse direction. Worm gear 103 drives worm wheel 102 to rotate in the reverse direction. Worm wheel 102 drives limit plate 1021 to move in the reverse direction. Under the reset action of reset spring 105, the protrusion moves towards the tail end of ball joint connecting pipe 101, driving sliding rod 106 to move towards the tail end of ball joint connecting pipe 101. The slider 1061 at the tail end of sliding rod 106 drives moving locking block 104 to move outside ball joint connecting pipe 101. Reset spring 107 resets. Gear 109 rotates in the reverse direction, driving rack 110 to return to its original position. The operator pulls out pipe 4. During the pulling process, sealing ring 108 will rotate and may be damaged. To ensure sealing during secondary use, the operator removes the used sealing ring 108 and replaces it with a new sealing ring 108. Then, the pipe 4 that needs to be fixed is inserted between moving locking blocks 104.

[0049] like Figure 8-10 As shown, the angle adjustment mechanism 2 includes a spherical sleeve 201, a second worm gear 202, a second worm 203, a rotation limit ring 204, and fixed blocks 205. The front end of the frustum of the ball joint connecting pipe 101 is movably installed inside the spherical sleeve 201. The rotation limit ring 204 is coaxially rotatably installed on the spherical sleeve 201. There are 15 fixed blocks 205, which are evenly distributed in a circle on the spherical sleeve 201 with the axis of the rotation limit ring 204 as the center. Each fixed block 205 is radially slidably installed on the spherical sleeve 201. Each fixed block 205 has a limiting slide rod 2051 at both ends. The rotating limiting ring 204 has a limiting groove 2041 corresponding to the limiting slide rod 2051. The limiting slide rod 2051 is slidably installed in the limiting groove 2041. The second worm gear 202 is coaxially fixedly connected to the rotating limiting ring 204 and rotatably installed on the spherical sleeve 201. The second worm 203 is rotatably installed on the spherical sleeve 201 and meshes with the second worm gear 202. A knob 2031 is coaxially fixedly installed at one end of the second worm 203.

[0050] The operator rotates the front end of the ball joint connecting pipe 101 to adjust the orientation angle of the ball joint connecting pipe 101, rotates the knob 2031, drives the worm gear 203 to rotate, the worm gear 203 drives the worm wheel 202 to rotate, the worm wheel 202 drives the rotation limit ring 204 to rotate, the limit groove 2041 on the rotation limit ring 204 moves, so that the limit rod 2051 moves from the end away from the axis of the rotation limit ring 204 to the end close to the axis of the rotation limit ring 204 within the limit groove 2041, driving the fixing block 205 to slide radially toward the axis of the rotation limit ring 204. All the fixing blocks 205 work together to fix the front end of the ball joint connecting pipe 101.

[0051] The operator rotates knob 2031 in the opposite direction, causing worm gear 203 to rotate in the opposite direction. This, in turn, causes worm wheel 202 to rotate the limiting ring 204 in the opposite direction. As a result, the limiting slide rod 2051 moves from the end closest to the axis of the limiting ring 204 to the end furthest from the axis of the limiting ring 204 within the limiting slide groove 2041. The fixing block 205 loosens the ball head connecting pipe 101, allowing the operator to adjust the orientation angle of the ball head connecting pipe 101 at the front end of the ball table again.

[0052] like Figure 10-12 As shown, the installation distance adjustment mechanism 3 includes a movable sleeve 301, an inner cylinder 302, and a second sealing ring 303; the inner cylinder 302 is slidably installed inside the movable sleeve 301, and the inner wall of the movable sleeve 301 and the outer wall of the inner cylinder 302 form a closed annular space, and the second sealing ring 303 is movably installed in the annular space; the movable sleeve 301 and the inner cylinder 302 are respectively fixedly installed on two symmetrically arranged spherical sleeves 201 and communicate with the corresponding spherical sleeves 201;

[0053] When adjusting the distance between the two spherical sleeves 201, the operator pulls the movable sleeve 301 and the inner cylinder 302, and the movable sleeve 301 and the inner cylinder 302 slide relative to each other, and move closer or further away from each other; during this process, the sealing ring 2 303 can always ensure the sealing between the movable sleeve 301 and the inner cylinder 302.

[0054] The operator adjusts the orientation of the pipe locking mechanism 1 on both sides using the angle adjustment mechanism 2 on both sides to adapt to the different orientation angles of the two pipes 4. The distance adjustment mechanism 3 is installed to adjust the distance between the two angle adjustment mechanisms 2 to adapt to the distance between the two pipes 4. The two pipe locking mechanisms 1 clamp the two pipes 4 with different diameters, thereby connecting the two pipes 4.
