Description

Technical Field

[0001] This application belongs to the field of gas pipelines, and particularly relates to a rotating joint for connecting gas pipelines. Background Art

[0002] A pipe joint is a connecting tool between pipes and is a detachable connection point between components and pipes, playing an indispensable and important role in pipe fittings. Among them, a pipe joint is an essential connecting piece in the process of gas use, and a gas pipe joint is mostly required to connect and seal between the connecting hose for gas inlet and the gas inlet of a gas stove.

[0003] The existing publication number CN219367081 U discloses a gas pipe joint with good airtightness, including a device body and a corrugated pipe. An inner joint is provided inside the device body, and a conical head is arranged inside the inner joint. The inner joint is sleeved at one end of the corrugated pipe, and a first thread is provided on the outside. An outer joint is arranged at the front end of the inner joint. A second thread is provided on the outer joint, and the second thread is screwed with the first thread. A plurality of elastic pieces are arranged inside the outer joint, and a limiting head is arranged inside the elastic pieces. The elastic pieces are located inside the conical head. A pressure sensor is installed at the upper end of the inner joint, and a buzzer alarm is installed on one side of the pressure sensor.

[0004] Although the above gas pipe joint can achieve quick disassembly and assembly of the inner joint, outer joint and corrugated pipe and has good airtightness, this joint cannot adjust the joint for gas pipes at different angular positions, and it is relatively inconvenient to install the gas pipe on the joint. Utility Model Content

[0005] The purpose of this application is to address the above-mentioned existing technical problems and provide a rotating joint for connecting gas pipelines, which can adjust the joint according to the position of the gas pipe, so that the two installation heads of the joint can be installed corresponding to the position angles of the two gas pipes, making the installation and connection of the gas pipe on the joint more convenient and efficient.

[0006] This application provides a rotating joint for connecting gas pipelines, including installation joints, and further including:

[0007] A connecting pipe. There are two installation joints, and the connecting pipe is installed between the two installation joints;

[0008] A first protective outer pipe, which is installed on the installation joint;

[0009] A second protective outer pipe, which is installed on the installation joint;

[0010] An adjusting component, which is installed on the second protective outer pipe and the second protective outer pipe;

[0011] Among them, the adjustment component includes a fixed plate, a rotating shaft, a rotating plate, and an adjustment component. The fixed plate is installed on the first protective outer tube, the rotating shaft is installed on the fixed plate, the rotating plate is installed on the rotating shaft, the rotating plate is connected and installed with the second protective outer tube, and the adjustment component is installed on the rotating plate.

[0012] When it is necessary to adjust the angle of the joint according to the position of the gas pipe, the adjustment component is used to rotate the rotating shaft on the fixed plate so that the rotating plate rotates around the axis of the rotating shaft. When the rotating plate rotates, it drives the second protective outer tube connected and installed with the rotating plate to rotate, and the included angle between the first protective outer tube and the second protective outer tube can be adjusted to adjust the angular position of the two installation joints connected to the connecting pipe in the two protective tubes. The adjustment component can adjust the joint according to the position of the gas pipe, so that the two installation heads of the joint can be installed corresponding to the position angles of the two gas pipes, making the installation and connection of the gas pipe to the joint more convenient and efficient.

[0013] Furthermore, the connecting pipe includes:

[0014] A first hose, which is installed on the installation joint;

[0015] A second hose, which is installed on the installation joint;

[0016] A corrugated pipe, one end of which is connected and installed with the first hose, and the other end is connected and installed with the second hose;

[0017] A limiting plate, which is installed in the first protective outer tube and the second protective outer tube to limit the first hose and the second hose.

[0018] When adjusting the angular position of the two installation joints connected to the connecting pipe in the two protective tubes by adjusting the included angle between the first protective outer tube and the second protective outer tube, the connecting pipe will be stretched and contracted. The connecting pipe is easily broken and gas leakage is likely to occur when it is stretched and contracted. Installing a corrugated pipe in the middle of the first hose and the second hose in a sealed manner makes the connecting pipe less likely to break when it is stretched and contracted, making the state of the connecting pipe more stable and safe when the joint is adjusted in angular position. The limiting plate provides a limit for the first hose and the second hose in the first protective outer tube and the second protective outer tube, making the position state of the first hose and the second hose more stable.

[0019] Furthermore, the adjustment component includes:

[0020] A fixed disk, which is installed on the rotating plate, and a through hole is provided on the fixed disk;

[0021] A rotating rod, which passes through the through hole on the fixed disk and is installed on the rotating shaft;

[0022] Rotating disk, the rotating disk is mounted on the rotating rod.

[0023] When adjusting the angle between the first protective outer tube and the second protective outer tube by driving the rotation of the rotating shaft through the component to be adjusted, the user holds the rotating disk and rotates it. The rotation of the rotating disk drives the rotating rod to rotate, and the rotation of the rotating rod drives the rotating shaft to rotate. Since the rotating shaft is fixedly connected to the rotating plate, when the rotating shaft rotates, the rotating plate will rotate around the axis of the rotating shaft. At this time, the angle between the first protective outer tube and the second protective outer tube can be adjusted according to the rotation angle of the rotating disk.

[0024] Furthermore, the rotating rod includes:

[0025] Bottom cylinder, the bottom cylinder is mounted on the rotating shaft, and the bottom cylinder is open at the top;

[0026] Tensile spring, the tensile spring is mounted inside the bottom cylinder;

[0027] Insertion cylinder, the insertion cylinder is inserted into the bottom cylinder, and at the same time the lower end of the insertion cylinder is connected to the tensile spring;

[0028] Limit block, the limit block is mounted on the rotating disk, and several limit blocks are provided;

[0029] Limit groove, the limit groove is provided on the fixed disk, and several limit grooves are provided.

[0030] When the user needs to drive the rotating disk to rotate the rotating rod, the user lifts the rotating disk. At this time, the insertion cylinder is pulled and moves upward in the bottom cylinder. At this time, the tensile spring is stretched. At this time, the limit block on the rotating disk disengages from the limit groove on the fixed disk. At this time, the limit of the rotating rod is released and it can be driven by the rotating disk to rotate to adjust the angle between the first protective outer tube and the second protective outer tube. When the adjustment is completed, the user stops applying an upward pulling force to the rotating disk. At this time, the tensile spring resets and contracts, driving the insertion cylinder to move downward in the bottom cylinder, and at the same time driving the limit block on the rotating disk to insert into the limit groove to lock the position of the rotating rod. At this time, it is impossible to drive the rotating rod to rotate the rotating shaft to complete the angular position locking of the first protective outer tube and the second protective outer tube, so that the installation head angle of the adjusted joint is not easy to loosen and change its position after facing backward.

[0031] Furthermore, the locking rotating rod further includes:

[0032] Insertion holes, several insertion holes are provided, and the insertion holes are evenly arranged around the axis of the bottom cylinder on the bottom cylinder;

[0033] Insertion strips, several insertion strips are provided, and the insertion strips are evenly arranged around the axis of the insertion cylinder on the insertion cylinder, and the insertion strips can be inserted into the corresponding insertion holes.

[0034] A number of the jacks are provided through the bottom cylinder, and the jacks are uniformly arranged on the bottom cylinder around the axis of the bottom cylinder. A number of the insertion strips are provided, and the insertion strips are uniformly arranged on the insertion cylinder around the axis of the insertion cylinder. The insertion strips can be inserted into the corresponding jacks. When the number of the insertion strips are inserted into the corresponding jacks, the insertion cylinder can successfully drive the bottom cylinder to rotate when rotating, avoiding the situation that the insertion cylinder rotates in the bottom cylinder but fails to drive the bottom cylinder to rotate.

[0035] Furthermore, a holding disc is arranged on the rotating disc, and friction lines are arranged on the holding disc. A holding disc is arranged on the rotating disc, and friction lines are arranged on the holding disc.

[0036] Since the cross-sectional diameter of the holding disc is larger than that of the rotating disc, it is more labor-saving and efficient for the user to drive the rotating disc to rotate by rotating the holding disc. At the same time, the friction lines on the holding disc can increase the friction force between the user's hand and the holding disc, making it less likely for the user to slip off when rotating the holding disc.

[0037] The beneficial effects of this application are as follows:

[0038] 1. The adjusting component can adjust the connector according to the position of the gas pipe, so that the two mounting heads of the connector can be installed corresponding to the position angles of the two gas pipes, making the installation and connection of the gas pipe to the connector more convenient and efficient;

[0039] 2. Installing a corrugated pipe in the middle of the first hose and the second hose in a sealed connection makes the connecting pipe less likely to break when stretching and contracting, and makes the state of the connecting pipe more stable and safe when the connector makes an angular position adjustment;

[0040] 3. When the rotating shaft rotates, the rotating plate will rotate around the axis of the rotating shaft. At this time, the included angle between the first protective outer pipe and the second protective outer pipe can be adjusted according to the rotation angle of the rotating disc.

[0048] Next, the embodiments of the present application will be described in detail in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0049] Embodiment 1:

[0050] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, the embodiment of the present application provides a rotating joint for connecting a gas pipeline, including an installation joint 100, and further including:

[0051] A connecting pipe 200, two installation joints 100 are provided, and the connecting pipe 200 is installed between the two installation joints 100;

[0052] A first protective outer pipe 300, the first protective outer pipe 300 is installed on the installation joint 100;

[0053] The second protective outer pipe 400, and the second protective outer pipe 400 is installed on the installation joint 100;

[0054] The adjusting assembly 500, and the adjusting assembly 500 is installed on the second protective outer pipe 400 and the second protective outer pipe 400;

[0055] Wherein, the adjusting assembly 500 includes a fixing plate 510, a rotating shaft 520, a rotating plate 530, and an adjusting assembly 540. The fixing plate 510 is installed on the first protective outer pipe 300, the rotating shaft 520 is installed on the fixing plate 510, the rotating plate 530 is installed on the rotating shaft 520, the rotating plate 530 is connected and installed with the second protective outer pipe 400, and the adjusting assembly 540 is installed on the rotating plate 530.

[0056] When the angle of the joint needs to be adjusted according to the position of the gas pipe, the adjusting assembly 540 is used to rotate the rotating shaft 520 on the fixing plate 510 so that the rotating plate 530 rotates around the axis of the rotating shaft. When the rotating plate 530 rotates, it drives the second protective outer pipe 400 connected and installed with the rotating plate 530 to rotate, and the included angle between the first protective outer pipe 300 and the second protective outer pipe 400 can be adjusted to adjust the angular position of the two installation joints 100 connected to the connecting pipe 200 in the two protective pipes. The adjusting assembly 500 can adjust the joint according to the position of the gas pipe, so that the two installation heads of the joint can be installed corresponding to the position angles of the two gas pipes, making the installation and connection of the gas pipe to the joint more convenient and efficient.

[0057] Embodiment 2:

[0058] As Figure 3 shown, the embodiment of the present application provides a rotating joint for connecting a gas pipeline. In addition to including the above technical features, the connecting pipe 200 includes:

[0059] The first hose 210, and the first hose 210 is installed on the installation joint 100;

[0060] The second hose 220, and the second hose 220 is installed on the installation joint 100;

[0061] The corrugated pipe 230, one end of the corrugated pipe 230 is connected and installed with the first hose 210, and the other end is connected and installed with the second hose 220;

[0062] The limiting plate 240, and the limiting plate 240 is installed in the first protective outer pipe 300 and the second protective outer pipe 400 to limit the first hose 210 and the second hose 220.

[0063] When adjusting the angle between the first protective outer tube 300 and the second protective outer tube 400 to adjust the angular positions of the two mounting joints 100 connected to the connecting tube 200 in the two protective tubes, the connecting tube 200 will be stretched and contracted. The connecting tube 200 is easily broken and gas leakage is likely to occur when it is stretched and contracted. A corrugated tube 230 is hermetically connected between the first hose 210 and the second hose 220, so that the connecting tube 200 is less likely to break when it is stretched and contracted, and the state of the connecting tube 200 is more stable and safe when the joint is adjusted in angular position. The limiting plate 240 provides a limit for the first hose 210 and the second hose 220 in the first protective outer tube 300 and the second protective outer tube 400, so that the position states of the first hose 210 and the second hose 220 are more stable.

[0064] Embodiment 3:

[0065] As Figure 2 、 Figure 4 shown, the embodiment of the present application provides a rotating joint for connecting a gas pipeline. In addition to including the above technical features, the adjusting assembly 540 includes:

[0066] A fixed disk 541, the fixed disk 541 is installed on the rotating plate 530, and through holes are provided on the fixed disk 541;

[0067] A rotating rod 542, the rotating rod 542 passes through the through hole on the fixed disk 541 and is installed on the rotating shaft 520;

[0068] A rotating disk 543, the rotating disk 543 is installed on the rotating rod 542.

[0069] When it is necessary to drive the rotating shaft 520 to rotate through the adjusting assembly 540 to adjust the angle between the first protective outer tube 300 and the second protective outer tube 400, the user holds the rotating disk 543 and rotates it. The rotating disk 543 rotates to drive the rotating rod 542 to rotate, and the rotating rod 542 rotates to drive the rotating shaft 520 to rotate. Since the rotating shaft 520 is fixedly connected to the rotating plate 530, when the rotating shaft 520 rotates, the rotating plate 530 will rotate around the axis of the rotating shaft 520. At this time, the angle between the first protective outer tube 300 and the second protective outer tube 400 can be adjusted according to the rotation angle of the rotating disk 543.

[0070] Embodiment 4:

[0071] As Figure 4 shown, the embodiment of the present application provides a rotating joint for connecting a gas pipeline. In addition to including the above technical features, the rotating rod 542 includes:

[0072] A bottom cylinder 551, the bottom cylinder 551 is installed on the rotating shaft 520, and the upper part of the bottom cylinder 551 is open;

[0077] When the user needs to drive the rotating disc 543 to rotate the rotating rod 542, the user lifts the rotating disc 543. At this time, the plug-in cylinder 553 is pulled to move upward inside the bottom cylinder 551. At this time, the tension spring 552 is stretched. At this time, the limit block 554 on the rotating disc 543 disengages from the limit slot 555 on the fixed disc 541. At this time, the limit of the rotating rod 542 is released and it can be driven by the rotating disc 543 to rotate to adjust the angle between the first protective outer tube 300 and the second protective outer tube 400. When the adjustment is completed, the user stops applying an upward pulling force to the rotating disc 543. At this time, the tension spring 552 resets and contracts, driving the plug-in cylinder 553 to move downward inside the bottom cylinder 551, and at the same time driving the limit block 554 on the rotating disc 543 to be inserted into the limit slot 555 to lock the position of the rotating rod 542. At this time, it is impossible to drive the rotating rod 542 to rotate the rotating shaft 520 to complete the angular position locking of the first protective outer tube 300 and the second protective outer tube 400, so that the installation head angle of the adjusted joint is not easy to loosen and change its position after facing backward.
