Description

Technical Field

[0001] The utility model relates to the technical field of propane gas cylinder connection, in particular to a gas cylinder expander installed at multiple stations. Background Art

[0002] Many scenarios requiring propane cylinders, such as outdoor adventures and industrial production, often face the problem of limited cylinder life. Traditional cylinder expanders typically only connect to a single cylinder, failing to meet the needs of long-term continuous use. When a cylinder runs out of gas, it needs to be interrupted to replace the cylinder, which brings inconvenience to work or activities and reduces efficiency. Therefore, designing an expander that can connect to multiple propane cylinders simultaneously has important practical value.

[0003] Existing gas cylinder expanders typically consist of an inlet, an outlet, and a conduit connecting the two. The gas cylinder and the expander's inlet are connected primarily through a threaded connection. Gas flows from the cylinder through the conduit and is then collected at the outlet, where it is then connected to the device through a connecting pipe. When connecting to the gas cylinder, the threaded parts on the cylinder or expander are usually manually rotated to secure the connection and prevent gas leakage.

[0004] The capacity of a single gas cylinder in an existing gas cylinder expander is limited. Frequent replacement of gas cylinders is not only troublesome, but may also cause gas leakage risks during the replacement process. When the gas outlet pipe is connected to the joint, other tools are needed to fix and tighten it, which increases the installation time of the equipment. Therefore, a multi-station installation gas cylinder expander is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a multi-station installed gas cylinder expander, which aims to improve the problem in the existing technology that the capacity of a single gas cylinder is limited. Frequent replacement of gas cylinders is not only troublesome, but may also cause gas leakage risks during the replacement process.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides an embodiment of a multi-station installed gas cylinder expander, comprising a box body 1, a handle 2 fixedly connected to the upper surface of the box body 1, which is convenient for users to carry the entire expander, and a connecting bracket 3 arranged inside the box body 1, whose main function is to provide an installation support position for multiple propane gas cylinders 6 to realize the function of multi-station installation of gas cylinders, and the side wall of the connecting bracket 3 fits into the inside of the fixing sleeve 4, so that the connecting bracket 3 can maintain a stable position in the box body 1, and a connecting sleeve 5 is arranged inside the connecting bracket 3, and the internal threaded connection of the connecting sleeve 5 is connected to the propane gas cylinder 6. The threaded connection can ensure that the propane gas cylinder 6 is tightly and firmly connected to the connecting bracket 3 to prevent the gas cylinder from loosening or falling off during use. The ball valve 7 arranged on the side wall of the connecting bracket 3 can effectively control the outflow and cutoff of the gas in the propane gas cylinder 6, and the outlet pipe 8 fixedly connected to the side wall of the ball valve 7 is a channel for gas to be transmitted from the gas cylinder to subsequent connecting components. The connection assembly, mounted on the sidewall of the outlet pipe 8, includes a retaining ring 9, which is internally fixedly connected to the sidewall of the outlet pipe 8 and provides positioning and support for the other components of the connection assembly. A push block 10, slidably connected to the sidewall of the outlet pipe 8, works in conjunction with a spring 12 and a sliding ball 13 to quickly connect and secure the connector 15 to the outlet pipe 8. A stop block 11, fixedly attached to the sidewall of the outlet pipe 8 and slidably connected to the inside of the push block 10, limits the sliding range of the push block 10 and prevents it from separating from the outlet pipe 8. The spring 12 is sleeved on the side wall of the air outlet pipe 8, one end of the spring 12 is fixedly connected to the side wall of the fixing ring 9, and the other end is fixedly connected to the side wall of the push block 10. The sliding ball 13 is slidably connected inside the air outlet pipe 8. Under the action of the spring 12 and the push block 10, the air outlet pipe 8 can be sealed and connected. The connecting pipe 14 fixedly connected to the side wall of the connector 15 is a component that transmits the gas output from the gas cylinder expander to the gas-using equipment. The pressure reducing valve 17 set on the side wall of the connecting pipe 14 can adjust the pressure of the output gas to meet the pressure requirements of the gas-using equipment, ensuring the normal operation and safe use of the gas-using equipment. A hole 16 is opened inside the connector 15, and the side wall of the sliding ball 13 is slidably connected inside the hole 16, providing a locking structure for the connection between the connector 15 and the air outlet pipe 8, ensuring the stability and sealing of the connection;

[0035] After the base 20 is installed, the valve cover 19 is removed from the side wall of the outlet pipe 8. When the outlet pipe 8 is not in use, the valve cover 19 effectively protects its port, preventing external impurities such as dust and moisture from entering the outlet pipe 8, ensuring the cleanliness of the gas transmission channel. Then, by toggling the push block 10, it squeezes and contracts the spring 12. The push block 10 serves as an operating component, facilitating the user to manually apply force. Through its linkage with the spring 12, it changes the elastic potential energy state of the spring 12, thereby causing the sliding ball 13 to lose its squeezed state. In the initial state, the sliding ball 13 is squeezed by the spring 12 through the push block 10 to a specific position in the outlet pipe 8, thereby sealing the outlet pipe 8 and preventing gas leakage. Next, insert the connector 15 into the outlet pipe 8 and align the hole 16 with the sliding ball 13. The connector 15 is a component that connects the outlet pipe 8 and the connecting pipe 14, and its structure is adapted to the outlet pipe 8. Then, loosen the push block 10, so that the spring 12 pushes the push block 10 to move, thereby squeezing the sliding ball 13 and pushing the sliding ball 13 into the hole 16. This connection method uses the elastic recovery force of the spring 12 to automatically achieve a quick locking connection between the connector 15 and the outlet pipe 8. It is easy to operate and the connection is stable, effectively reducing the time and energy consumption of fixing and tightening with complex tools in the traditional connection method, thereby completing the connection with the connecting pipe 14. Then, connect the other end of the connecting pipe 14 to the gas equipment. The connecting pipe 14 serves as an intermediate bridge for gas transmission, accurately delivering the gas output from the gas cylinder expander to the gas equipment. The gas equipment can be ignited by starting the pressure reducing valve 17. The pressure reducing valve 17 can accurately adjust the gas pressure, reducing the high-pressure gas output from the gas cylinder expander to the appropriate pressure range required by the gas equipment, ensuring the normal operation of the gas equipment under safe and stable gas pressure conditions, avoiding equipment damage or safety accidents caused by excessive gas pressure, and also ensuring the full combustion and efficient use of the gas.

[0036] Reference Figure 3 and Figure 5The fixing component includes a base 20, the side walls of the base 20 are attached to the lower surface of the box body 1, and its main function is to provide a stable placement foundation for the entire gas cylinder expander, so that the expander can be placed stably on various planes to avoid tipping or shaking due to unstable placement. The fixing block 21 fixedly connected to the upper surface of the base 20 is made of rubber material. On the one hand, it has a certain elasticity and can play a buffering role when the propane cylinder 6 is placed inside the installation groove 22, reducing damage to the cylinder caused by vibration or collision; on the other hand, the friction of the rubber material is large, which can increase the friction on the propane cylinder 6, preventing the cylinder from sliding or displacing at will in the installation groove 22, and further ensuring the stable installation of the cylinder. The mounting groove 22 defined within the fixing block 21 is shaped to match the sidewall of the propane cylinder 6, allowing the propane cylinder 6 to be accurately inserted therein, precisely positioning and securing the cylinder. The magnetic block 1 23 fixedly attached to the base 20 attracts the magnetic block 2 24 fixedly attached to the housing 1. This magnetic structure enhances the tightness and stability of the connection between the base 20 and the housing 1, preventing accidental separation or misalignment between the base 20 and the housing 1 during movement or use, thereby ensuring the structural integrity and reliability of the entire cylinder expander. The fixing ring 18 fixedly attached to the sidewall of the outlet pipe 8 provides a secure connection point for the valve cover 19, which slides internally onto the sidewall of the outlet pipe 8. The valve cover 19 protects the outlet pipe 8 port, preventing dust, impurities, and other foreign matter from entering the outlet pipe 8 and potentially affecting normal gas transmission or causing blockage. Furthermore, when the outlet pipe 8 is not in use, the valve cover 19 seals the outlet pipe 8 port, further enhancing the safety and sealing of the entire cylinder expander.

[0037] To use the device, first connect the propane cylinder 6 to it via the connecting sleeve 5. The threaded structure inside the connecting sleeve 5 matches the threads on the mouth of the propane cylinder 6. A twisting operation secures the two together, forming a stable and reliable connection. This connection not only prevents leakage during gas transmission but also withstands a certain pressure, ensuring smooth gas flow from the cylinder to the expander, thus completing the installation of the propane cylinder 6. Next, the fixing block 21 is slid into the interior of the housing 1. Because the fixing block 21 is made of rubber and has a certain degree of elasticity, the rubber's elasticity allows it to adapt to the spatial shape and size differences within the housing 1 as it slides into the housing 1, smoothly entering the designated position and tightly fitting inside the housing 1. This tight fit not only reduces the gap between the fixing block 21 and the housing 1, preventing friction noise caused by shaking during use, but also enhances the stability of the overall structure to a certain extent, preventing the loosening of the fixing block 21 from affecting the secure installation of the propane cylinder 6. Then, through the mutual attraction between magnetic block 1 23 and magnetic block 2 24, the attraction generated by this magnetic effect can accurately position the base 20 at the appropriate position below the box body 1, so that the side wall of the propane cylinder 6 can be stably fitted inside the mounting groove 22. The shape and size of the mounting groove 22 are highly adapted to the side wall of the propane cylinder 6, which can effectively limit the horizontal displacement of the propane cylinder 6. In addition, the magnetic fixation further prevents the cylinder from jumping or detaching in the vertical direction. At this point, the installation of the base 20 is completed. The entire installation process, through the coordinated action of various components, realizes the safe, stable and convenient installation of the propane cylinder 6 in the cylinder expander, laying a solid foundation for the normal operation and gas supply of subsequent equipment.

[0038] Working principle: When using the device for work, first connect the propane cylinder 6 to it through the connecting sleeve 5 to complete the installation of the propane cylinder 6, then slide the fixing block 21 into the interior of the box 1. Since the fixing block 21 is made of rubber material and has a certain elasticity, it fits the interior of the box 1. Then, the magnetic block 1 23 and the magnetic block 2 24 attract each other, so that the side wall of the propane cylinder 6 fits inside the installation groove 22. At this time, the installation of the base 20 is completed. Then, remove the valve cover 19 from the side wall of the outlet pipe 8, and then By moving the push block 10, the spring 12 is squeezed and contracted, thereby releasing the squeezed state of the sliding ball 13. Then, the connector 15 is inserted into the outlet pipe 8, and the hole 16 is aligned with the position of the sliding ball 13. Then, the push block 10 is released, and the spring 12 pushes the push block 10 to move, thereby squeezing the sliding ball 13 and pushing the sliding ball 13 into the hole 16, thereby completing the connection with the connecting pipe 14. Then, the other end of the connecting pipe 14 is connected to the gas equipment, and the gas equipment can be ignited by starting the pressure reducing valve 17.
