Technical Field

[0001] The utility model relates to the technical field of gas pipe connection, in particular to a gas pipeline connection device. Background Art

[0002] Gas is a general term for gaseous fuels, which can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. When gas is transported, it needs to be transported using gas pipes;

[0003] The gas pipe is a special pipeline for transporting combustible gas. It is a metal gas pipe hose that replaces the traditional clip-on rubber hose. It can solve the defects of rubber hoses that are easy to fall off, easy to age, easy to be bitten by insects, and have a short service life. When connecting and installing the gas pipe, it is usually necessary to use a special connection device to connect it to avoid gas leakage.

[0004] When the existing gas pipe connecting device is used, the gas pipes on both sides often do not fit each other after the gas pipe is inserted into the connecting device, which causes gas to leak easily from the gap between the two gas pipes; therefore, it does not meet the existing needs. In this regard, we propose a gas pipeline connecting device. Utility Model Content

[0005] The utility model aims to provide a gas pipeline connecting device to solve the problem that the gas pipe connecting device proposed in the above-mentioned background technology often fails to fit each other after the gas pipe is inserted into the connecting device, which causes gas to leak easily from the gap between the two gas pipes.

[0007] Preferably, the top surfaces at both ends of the sliding groove are provided with lifting grooves, the top of the connector is provided with a connector top groove, the connector top groove and the lifting groove are through-connected, and a sliding buckle is fixedly installed on the top of the upper semicircular clamping plate, the sliding buckle slides into the interior of the connector top groove, and the upper semicircular clamping plate slides into the interior of the lifting groove.

[0008] Preferably, tension springs are movably mounted at both ends of the upper semicircular clamping plate and the lower semicircular clamping plate, and both ends of the tension springs are fixedly connected to the surfaces of the upper semicircular clamping plate and the lower semicircular clamping plate, respectively.

[0009] Preferably, T-shaped limit plates are fixedly installed on the surfaces of the upper semicircular clamping plate and the lower semicircular clamping plate, limit plate slide grooves are provided above and below the interior of the sliding groove, the T-shaped limit plate slides into the interior of the limit plate slide groove, and a limit plate lifting groove is provided at the top of the lifting groove, and the T-shaped limit plate located on the surface of the upper semicircular clamping plate slides into the interior of the limit plate lifting groove.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model uses the cooperation of the upper semicircular clamping plate and the lower semicircular clamping plate to clamp the gas pipe, and then drives the compression spring to move toward the center of the connector through the elastic potential energy, so that the two gas pipes fit closely and avoid the situation where a gap is generated between the gas pipes;

[0012] 2. The utility model cooperates with the lifting slot and the limiting plate lifting slot so that the upper semicircular clamping plate can be pulled upward to expand the gap between the upper semicircular clamping plate and the lower semicircular clamping plate after moving to the two end positions of the sliding slot, so that the gas pipe can be better placed in the position between the upper semicircular clamping plate and the lower semicircular clamping plate to avoid the gas pipe being stuck. The connection between the upper semicircular clamping plate and the lower semicircular clamping plate can be reinforced by the tension spring. After the gas pipe is inserted between the upper semicircular clamping plate and the lower semicircular clamping plate, the upper semicircular clamping plate and the lower semicircular clamping plate can be tightened by the tension spring, so that the gas pipe is clamped by the upper semicircular clamping plate and the lower semicircular clamping plate, avoiding the situation where the gas pipe does not move when the upper semicircular clamping plate is pushed by the compression spring.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 4 The utility model provides an embodiment: a gas pipeline connection device, including a gas pipe 1, a connector 2 movably installed between two gas pipes 1, a sliding groove 4 is provided inside the connector 2, two upper semicircular clamping plates 7 are slidably installed near the upper position inside the sliding groove 4, and two lower semicircular clamping plates 13 are slidably installed near the lower position inside the sliding groove 4, and the gas pipe 1 is movably clamped into the upper semicircular clamping plates 7 and the lower semicircular clamping plates 13, and compression springs 6 are movably installed between the upper semicircular clamping plates 7 and the lower semicircular clamping plates 13 and the two ends inside the sliding groove 4. Through the cooperation of the upper semicircular clamping plates 7 and the lower semicircular clamping plates 13, the upper semicircular clamping plates 7 and the lower semicircular clamping plates 13 can clamp the gas pipe 1, and then the elastic potential energy of the compression spring 6 drives the movement toward the center position of the connector 2, so that the two gas pipes 1 are closely fitted to avoid the situation where a gap is generated between the gas pipes 1.

[0021] The top surfaces of both ends of the sliding groove 4 are provided with lifting grooves 5, and the top of the connector 2 is provided with a connector top groove 3. The connector top groove 3 and the lifting groove 5 are through-connected. A sliding buckle 8 is fixedly installed on the top of the upper semicircular clamping plate 7. The sliding buckle 8 slides into the interior of the connector top groove 3, and the upper semicircular clamping plate 7 slides into the interior of the lifting groove 5.

[0022] Tension springs 10 are movably mounted at both ends of the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 , and both ends of the tension spring 10 are fixedly connected to the surfaces of the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 , respectively. By cooperating with the lifting groove 5 and the limiting plate lifting groove 11, the upper semicircular clamping plate 7 can be pulled upward to expand the gap between the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 after moving to the two end positions of the sliding groove 4, so that the gas pipe 1 can be better placed in the position between the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 to avoid the gas pipe 1 being stuck, and the connection between the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 can be reinforced by the tension spring 10, so that after the gas pipe 1 is inserted between the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13, the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 can be tightened by the tension spring 10, so that the gas pipe 1 is clamped by the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13, avoiding the situation that the gas pipe 1 does not move when the upper semicircular clamping plate 7 is pushed by the compression spring 6.

[0023] The surfaces of the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 are fixedly mounted with T-shaped limit plates 9, and limit plate slide grooves 12 are arranged above and below the interior of the sliding groove 4. The T-shaped limit plate 9 slides and snaps into the interior of the limit plate slide groove 12, and a limit plate lifting groove 11 is arranged at the top of the lifting groove 5. The T-shaped limit plate 9 located on the surface of the upper semicircular clamping plate 7 slides and snaps into the interior of the limit plate lifting groove 11. The upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 are limited by the T-shaped limit plate 9 to prevent the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 from rotating inside the sliding groove 4, and the setting of the limit plate lifting groove 11 allows the T-shaped limit plate 9 installed on the surface of the upper semicircular clamping plate 7 to be lifted and lowered inside the limit plate rope groove 11 when the upper semicircular clamping plate 7 is pulled upward by the sliding buckle 8, so as to prevent the upper semicircular clamping plate 7 from being stuck.

[0024] When the gas pipeline connection device is in use, the first gas pipe 1 is first inserted into one end of the connector 2, and the sliding buckle 8 close to the first gas pipe 1 is pulled to move it to one end position of the connector top groove 3. At this time, the sliding buckle 8 is pulled upward, so that the sliding buckle 8 drives the upper semicircular clamping plate 7 to move upward, so that the upper semicircular clamping plate 7 rises a part of the inside of the lifting groove 5, so that the gap between the upper semicircular clamping plate 7 and the lower semicircular clamping plate 13 is expanded. At this time, the state of the connector 2 is the same as that of the lower semicircular clamping plate 13. Figure 3The upper and lower semicircular clamping plates 7 and 13 are aligned, and the gas pipe 1 is then moved inwardly to be inserted into the internal position between the upper and lower semicircular clamping plates 7 and 13, and the sliding buckle 8 is released. At this time, the upper and lower semicircular clamping plates 7 are pressed down by the elastic potential energy of the tension spring 10 to clamp the gas pipe 1, and then the upper and lower semicircular clamping plates 7 are moved toward the center position of the connector top groove 3 by the elastic potential energy of the compression spring 6, so that the upper and lower semicircular clamping plates 7 and 13 bring the gas pipe 1 into the internal position of the connector 2. At this time, the state of the connector 2 is the same as that of the lower and upper semicircular clamping plates 13. Figure 2 Consistency;

[0025] Then, the second gas pipe 1 is inserted into the interior of the connector 2 in the same way, so that the two upper semicircular clamping plates 7 and the two lower semicircular clamping plates 13 are clamped by the upper semicircular clamping plates 7 and the lower semicircular clamping plates 13, and are moved toward the center position of the connector 2 by the elastic potential energy of the compression spring 6. When the surfaces of the two gas pipes 1 are in contact, the elastic potential energy of the compression springs 6 on both sides is consistent, so that the upper semicircular clamping plates 7 and the lower semicircular clamping plates 13 on both sides stop moving, thereby connecting and sealing the two gas pipes 1 to each other, avoiding the situation where a gap is generated between the two gas pipes 1 during installation, thereby causing gas leakage.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
