[0002] As an important power source for devices, high-pressure gas is widely used in various application scenarios. Gas cylinders are used as storage devices for high-pressure gas, which store and release high-pressure gas to provide power for the device. In order to take the high-pressure gas out of the gas cylinder, it is necessary to connect the gas cylinder to the gas-using device. The existing connection methods all use gas valves to achieve the best connection effect and safety performance. However, the existing connection methods are complicated when connecting gas cylinders. It takes a long time to complete the connection of the gas cylinders. In addition, the safety performance of the connection cannot be effectively guaranteed, and monitoring and pressure relief cannot be implemented. Utility Model Content
[0003] In order to solve the above problems, the utility model provides a novel quick plug-in and pull-out gas source device, which realizes quick plug-in and pull-out of gas cylinders by arranging fasteners that can be quickly connected, and realizes quick locking through a locking device.

The gas cylinder can be installed in the frame through the opening. The pressure relief device is installed on the frame. A deflation valve is installed on the top of the gas cylinder. The connection between the gas cylinder and the gas-using device is achieved by connecting the deflation valve and the pressure relief device. The pressure relief device consists of a pressure relief valve and a connecting valve. The pressure relief valve is connected to the connecting valve to provide pressure relief when the pressure is too high. The connecting valve matches the deflation valve.

In order to prevent the gas cylinder from rotating during use, causing the connection part to loosen and leak, a locking device is provided on the side of the bottom of the gas cylinder, and a locking hole is provided on the side of the frame opening. The locking device corresponds to the locking hole and can be stuck in the locking hole to prevent the gas cylinder and the frame from rotating relative to each other.
[0006] Furthermore, the locking device is composed of a bolt, a spring and a bolt sleeve. The bolt can be movably inserted into the bolt sleeve, and the end of the bolt can be inserted into the locking hole. Position locking is achieved by inserting the bolt into the locking hole.

DETAILED DESCRIPTION
[0017] To further illustrate the concept of the present invention, the following will further illustrate the specific implementation of the present invention in conjunction with the accompanying drawings:
[0018] A novel quick-plug gas source device comprises a gas cylinder 1, a frame 2 and a pressure relief device, such as Figure 1 , Figure 2 As shown. Take a sealed high-pressure bottle as the gas cylinder 1, install a safety valve 19, an air inlet valve 20 and a pressure gauge 21 at the bottom of the gas cylinder 1, and install a deflation valve 3 at the top of the gas cylinder 1. Then take a steel ring with the same diameter as the gas cylinder 1, bend the two ends of a steel bar and weld them to the steel ring to form a handle 8, and weld the steel ring to the bottom of the gas cylinder 1. Take a cylinder as the latch sleeve 13, weld a steel ring inside one end of the latch sleeve 13 as a clamping plate 17, then take a metal rod with the same inner diameter as the steel ring as the latch 11, weld a steel ring as a clamping ring 15 at one end of the latch 11 near the end, then put the spring 12 on the latch 11 from the other end, insert the latch 11 from the end of the latch sleeve 13 without the clamping plate 17, so that the spring 12 is located between the clamping ring 15 and the clamping plate 17, after the latch 11 passes through the clamping plate 17, use bolts to fix a metal block as a stop block 14 on the side of the end of the latch 11 passing through the clamping plate 17, and then open a stop groove 16 on the latch sleeve 13 to accommodate the stop block 14, so as to make a locking device 9, such as Figure 4 , Figure 5 As shown, the locking device 9 is welded to the outer side of the steel ring of the handle 8.
[0019] Take a cylinder with the same inner diameter as the outer diameter of the gas cylinder 1 as the frame 2, and seal one end of the cylinder. Install a connecting valve 5 in the middle of the sealed end of the cylinder, and the connecting valve 5 and the air release valve 3 of the gas cylinder 1 can be connected to each other. Weld a cylinder as a fastener 6 on the outside of the connecting valve 5, and open a thread on the inner side wall of the fastener 6 to form a threaded sleeve 7, as shown in FIG. Figure 3 As shown, an external thread is then opened on the outside of the air release valve 3 so that the threaded sleeve 7 can be threadedly connected to the external thread. Then a pressure relief valve 4 and a temperature and pressure sensor 18 are connected to the connecting valve 5 to form a pressure relief device. Finally, a metal ring is welded on the outside of the open end of the frame 2 as a locking hole 10. It is necessary to ensure that when the latch sleeve 13 and the locking hole 10 are opposite, the end of the latch 11 can be inserted into the locking hole 10.
[0020] When installing the gas cylinder 1, insert the gas cylinder 1 into the frame 2 from the open end of the frame 2, so that the air release valve 3 of the gas cylinder 1 is opposite to the connecting valve 5, and continue to push the gas cylinder 1 to make the air release valve 3 and the connecting valve 5 contact. After the air release valve 3 and the connecting valve 5 are in contact, rotate the gas cylinder 1 through the handle 8 to allow the fastener 6 and the air release valve 3 to be threadedly connected through the threaded sleeve 7 and the external thread. During this process, the air release valve 3 and the connecting valve 5 are close to each other, so that the valve cores of the two valve bodies are in contact with each other, thereby connecting the gas path. When the air release valve 3 and the connecting valve 5 are fully connected, adjust the angle of the gas cylinder 1 through the handle 8 so that the locking device 9 is opposite to the locking hole 10, insert the pin 11 into the locking hole 10, and make the stop block 14 fit into the stop groove 16, thereby fixing the position of the gas cylinder 1. During use, the pin 11 is inserted into the locking hole 10, so that the angle of the gas cylinder 1 is completely fixed and cannot rotate, thereby preventing the threaded connection between the air release valve 3 and the connecting valve 5 from loosening and preventing gas leakage. At the same time, the internal gas environment can be monitored by the pressure gauge 21 at the bottom of the gas cylinder 1 and the temperature and pressure sensor 18 on the connecting valve 5. When the internal pressure is too high, the gas can also be released through the safety valve 19 at the bottom of the gas cylinder 1 and the pressure relief valve 4 on the connecting valve 5 to ensure the internal pressure safety. When the internal gas is insufficient, gas can be replenished through the air inlet valve 20 at the bottom of the gas cylinder 1.
[0021] When it is necessary to disassemble the gas cylinder 1, the stop block 14 is pulled outward from the stop groove 16, and then the latch 11 is rotated to make the stop block 14 lean against the end of the latch sleeve 13. At this time, the latch 11 is disengaged from the locking hole 10, and the gas cylinder 1 can be rotated by rotating the handle 8. The threaded connection part of the air release valve 3 and the connecting valve 5 is separated by the rotation of the gas cylinder 1. During the separation process, the valve cores of the air release valve 3 and the connecting valve 5 gradually return to their original positions to disconnect the gas path. When the air release valve 3 and the connecting valve 5 are completely separated, the gas cylinder 1 can be directly taken out from the open end of the frame 2.

For those skilled in the art, various changes and variations are possible. Any modifications, equivalent substitutions, improvements, etc. made using the present invention should be included in the protection scope of the present invention.
