[0002] During the construction of pressure pipelines, the area is measured and the pipeline network is designed in advance to facilitate the rational installation of pipelines. The connection between each section of pipeline is carried out in different ways depending on factors such as material. Rigid pipelines are connected by welding, flanges, threads, etc., while deformable hoses are connected by heat fusion or by adding pipe joints.

[0003] Chinese patent CN215763831U discloses an angle-adjustable pipe connection structure with a fixed structure, including a connecting flange, a flexible corrugated pipe and an angle adjustment sleeve. The connecting flange is detachably connected to both ends of the flexible corrugated pipe, and the angle adjustment sleeve has two sets of symmetrically arranged rotating lugs on both sides.

[0004] Regarding this disclosed technology, when laying out pipes, it is necessary to bypass objects, resulting in non-standard angles required for construction. Deformable flexible hoses can freely adjust their angles without the need for auxiliary adjustment of pipe rotation. Furthermore, the structure has a large number of gaps on its surface, making it unsuitable for rigid pipes and limiting its applicability. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a pipe connection device to solve the issue of the difficulty in quickly adjusting the bend angle of rigid pipes.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: a pipe docking device, including a steering mechanism and an extension mechanism. The steering mechanism includes a flange, a steering sleeve, a steering ball tube, and a clamping component. The steering sleeve is fixedly installed at the front end of the flange, and the steering ball tube is slidably installed on the front side of the steering sleeve. The cross-section of the steering ball tube is spherical, and its two inlet and outlet ends are located inside and outside the steering sleeve, respectively. A clamping component is installed on the internal thread of the flange. The moving end of the clamping component fits against the connection between the steering ball tube and the steering sleeve.

[0008] A baffle is fixedly installed on the front side of the steering sleeve. The baffle is in contact with the ball surface of the steering ball tube. There are two sets of baffles. The baffle located at the rear is in contact with the seal at the clamping part.

[0009] The clamping component includes a push ring, a sliding plate, a positioning ring, and a first sealing ring. The push ring is threadedly installed inside the flange. An annular groove is provided on the front side of the push ring, and a sliding plate is slidably installed inside the annular groove. A positioning ring is fixedly installed at the front end of the sliding plate. The positioning ring is in contact with the spherical surface of the steering ball tube. A first sealing ring is fixedly connected to the front side of the positioning ring. The first sealing ring is tightly attached to the connection between the steering ball tube and the steering sleeve.

[0010] The inner sleeve includes a first cylinder, a groove, a second sealing ring, a compression ring, and a third sealing ring.

A seal is provided at the connection between the rotating end of the inner sleeve 5 and the outer sleeve 6.

[0026] Specifically, flange 1 is fixed to the flange of the pipe to be connected, the rotation range of the directional ball tube 3 is limited by the directional sleeve 2, the angle of pipe connection is adjusted by the rotation of the directional ball tube 3 inside the directional sleeve 2, the clamping member 4 moves inside the flange 1 and the directional sleeve 2 to squeeze and limit the directional ball tube 3, the inner sleeve 5 is connected to the front end of the directional ball tube 3, and the overall length of the inner sleeve 5 and the outer sleeve 6 is adjusted according to the relative position of the pipe to be connected by the sliding connection between the outer sleeve 6 and the inner sleeve 5.

[0027] A baffle is fixedly installed on the front side of the steering sleeve 2. The baffle is in contact with the ball surface of the steering ball tube 3. There are two sets of baffles. The baffle at the rear position is in contact with the seal at the clamping part 4.

[0028] Specifically, the steering ball tube 3 is restricted from rotation by the baffle of the steering sleeve 2, so that it slides stably on the front side of the steering sleeve 2.

[0029] The clamping component 4 includes a push ring 401, a slide plate 402, a positioning ring 403, and a first sealing ring 404. The push ring 401 is threadedly installed inside the flange 1.

[0030] Specifically, by pushing the push ring 401 to rotate inside the flange 1, the slide plate 402 slides inside the annular groove of the push ring 401. The push ring 401 pushes the slide plate 402 and the positioning ring 403 forward until the positioning ring 403 contacts the surface of the steering ball tube 3, thereby restricting the rotation of the steering ball tube 3. The positioning ring 403 pushes the first sealing ring 404 to press tightly against the connection between the baffle of the steering sleeve 2 and the steering ball tube 3, thereby sealing it.

[0031] The inner sleeve 5 includes a first cylinder 501, a groove 502, a second sealing ring 503, a compression ring 504, and a third sealing ring 505. The first cylinder 501 is threadedly installed inside the front end of the steering ball tube 3. The groove 502 is provided on the surface of the first cylinder 501.

The groove 502 allows the outer sleeve 6 to slide stably on the surface of the inner sleeve 5. By twisting the compression ring 504 to squeeze the third sealing ring 505, the third sealing ring 505 seals the connection between the first cylinder 501 and the outer sleeve 6.

[0033] The number of grooves 502 is multiple and arranged in a circular array on the surface of the first cylinder 501. The grooves 502 are provided with positioning holes, and the number of positioning holes is multiple and arranged at equal intervals inside the grooves 502.

[0034] Specifically, the outer sleeve 6 is fixed to various parts of the surface of the inner sleeve 5 by means of multiple sets of positioning holes in the groove 502.

[0035] The outer sleeve 6 includes a second cylinder 601, a slider 602, and a limiting bolt 603. The second cylinder 601 is slidably sleeved on the surface of the first cylinder 501.

[0036] Specifically, by tightening the limiting bolt 603, the limiting bolt 603 passes through the interior of the second cylinder 601 and the slider 602, thereby fixing the slider 602 to the inner wall of the second cylinder 601. By continuing to tighten the limiting bolt 603, it is inserted into the positioning hole of the groove 502, thereby connecting and fixing the outer sleeve 6 and the inner sleeve 5.

[0037] In summary: When using this utility model, if the bending angle of two sets of pressure pipelines is not a standard angle, the two sets of inner sleeves 5 can be installed inside the same set of outer sleeves 6. The steering ball tube 3 is rotated at one end of the steering sleeve 2 until a suitable angle is reached, then the steering ball tube 3 is fixed. The two sets of flanges 1 are then fixed to the ends of the two sets of pipelines to achieve a non-standard angle bend at the pipeline connection. When adjusting the angle, according to the required bending angle of the pipeline to be connected, the steering ball tube 3 is pushed to slide at the front end of the steering sleeve 2 until a suitable position is reached. Then, the push ring 401 is rotated, causing the sliding plate 402 to push... The push ring 401 slides inside the annular groove on the front side, pushing the slide plate 402 and positioning ring 403 to move. The positioning ring 403 contacts the surface of the steering ball tube 3, applying pressure to the surface of the steering ball tube 3 and fixing it to the front side of the steering sleeve 2. At the same time, the positioning ring 403 pushes the first sealing ring 404 to make it tightly adhere to the connection between the baffle of the steering sleeve 2 and the steering ball tube 3, sealing the gap. According to the position of the pipe to be connected, the lengths of the inner sleeve 5 and the outer sleeve 6 are adjusted, pushing the two sets of inner sleeves 5 to slide inside the two ends of the outer sleeve 6, adjusting the total length of the inner sleeve 5 and the outer sleeve 6. Extend or shorten the sleeve by tightening the limiting bolt 603 to insert it into the positioning hole of the groove 502, connecting and fixing the inner sleeve 5 and the outer sleeve 6. Tighten the compression ring 504 to compress the third sealing ring 505, making it tightly adhere to the connection between the first cylinder 501 and the second cylinder 601 to seal the gap. Then connect the two sets of inner sleeves 5 to the two sets of steering ball tubes 3 respectively. Rotate the outer sleeve 6 to make the inner sleeve 5 rotate, connecting the first cylinder 501 to one end of the steering ball tube 3, and making the first cylinder 501 compress the second sealing ring 503, making it tightly adhere to the connection between the steering ball tube 3 and the first cylinder 601. At the connection of body 501, the gap is sealed. When the docking mechanism needs to be disassembled, the push ring 401 is turned in the opposite direction to disengage it from the flange 1. The clamping part 4 can then be removed from the inside of the flange 1 and the steering sleeve 2. The first sealing ring 404 can be replaced. The limit bolt 603 is turned to separate it from the second cylinder 601 and the slider 602. The slider 602 can then be separated from the second cylinder 601, completing the separation of the inner sleeve 5 and the outer sleeve 6. The third sealing ring 505 can then be replaced. The second sealing ring 503 can be replaced by separating the inner sleeve 5 and the steering ball tube 3.
