Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide supply, and in particular to a carbon dioxide supply connection device with replaceable connectors. Background Technology

[0002] A carbon dioxide supply device is a device used to store, transport, and control the supply of carbon dioxide gas. It is widely used in many fields such as industry, medicine, and food and beverage. It consists of a storage container, a pressure reducing device, a flow control device, connecting pipes, and safety devices. In welding processes, carbon dioxide is used as a protective gas to prevent oxidation of the weld and improve welding quality. In metal processing, it is used for the treatment and protection of metal surfaces. In chemical production, it participates in chemical reactions as a raw material or reaction medium.

[0003] The carbon dioxide gas inside the cylinder is in a gaseous or liquid state under high pressure. When the cylinder valve is opened, the gas enters the pressure reducing device through the connecting pipeline. The pressure reducing device lowers the gas pressure to a set value. Then, it passes through the flow control device, which precisely adjusts the gas flow rate according to the user's needs. Finally, it is delivered to the equipment or location using the gas through the connecting pipeline. Throughout the entire process, safety devices monitor parameters such as pressure in real time to ensure the safe operation of the device.

[0004] In carbon dioxide supply systems, the gas cylinders need to be replaced promptly after the gas is depleted. The inconvenience of disassembling the connectors makes cylinder replacement cumbersome, increases the workload of operators, and may lead to prolonged gas supply interruptions. Furthermore, significant time is spent disassembling the connectors during maintenance of the carbon dioxide supply system, impacting work efficiency. Utility Model Content

[0005] This is to overcome the technical problem that the inconvenience of disassembling the connector makes the process of changing gas cylinders cumbersome and increases the workload of operators.

[0006] The technical solution of this utility model is as follows: a carbon dioxide gas supply connection device with replaceable connector, including a gas storage tank, a limiting block and a locking component. A connecting pipe is fixedly connected to the top of the gas storage tank. A locking component is provided on one side of the connecting pipe. Four sets of square grooves are evenly opened inside the connecting pipe. A limiting block is slidably connected inside the square groove. A sliding rod is fixedly connected to one side of the limiting block. The other side of the sliding rod passes through the connecting pipe and slides inside the square groove. A fixing plate is provided on the other side of the sliding rod. A spring is fixedly connected to one side of the limiting block. The other side of the spring is fixedly connected to one end of the square groove.

[0007] Preferably, a transport pipe is installed above the connecting pipe.

[0008] Preferably, an annular locking block is fixedly connected to the outside of the transport pipe.

[0009] Preferably, an arc-shaped locking block is slidably connected to the outside of the transport pipe, and the arc-shaped locking block is positioned above the annular locking block.

[0010] Preferably, the inclined surface of the annular block has the same inclination angle as the inclined surface of the limiting block.

[0011] Preferably, an installation plate is fixedly connected inside the connecting pipe, a second spring is fixedly connected above the installation plate, and a sealing ring is fixedly connected above the second spring.

[0012] Preferably, a second sealing ring is installed above the connecting pipe.

[0013] The beneficial effects of this utility model are as follows: Through ingenious structural design, this utility model aligns the annular locking block of the transport pipe with the connecting pipe, pushes the transport pipe, and the annular locking block compresses the limiting block, causing the limiting block to push the sliding rod to slide inside the square groove, compressing the spring. When the annular locking block reaches the appropriate position, the spring pushes the limiting block to reset, fixing the annular locking block and achieving locking. By pushing the transport pipe downward, the arc-shaped locking block slides downward. When it slides to the position where it abuts the annular locking block, it compresses the limiting block, thereby allowing the transport pipe to be removed from the connecting pipe for easy replacement. When the annular locking block reaches the locked position, the limiting block with the same tilt angle can fit tightly with the annular locking block. Through the action of the spring, the limiting block tightly abuts the annular locking block, preventing the transport pipe from moving or separating from the connecting pipe.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6 This utility model provides an embodiment of a carbon dioxide supply connection device with replaceable connectors, including a gas storage tank 101, a limiting block 104, and a locking component. A connecting pipe 102 is fixedly connected to the top of the gas storage tank 101. A locking component is provided on one side of the connecting pipe 102. Four sets of square grooves 103 are evenly distributed inside the connecting pipe 102. The limiting block 104 is slidably connected inside the square grooves 103. A sliding rod 105 is fixedly connected to one side of the limiting block 104. The other side of the sliding rod 105 passes through the connecting pipe 102 and slides inside the square grooves 103. A fixing plate 106 is provided on the other side of the sliding rod 105. A spring 107 is fixedly connected to one side of the limiting block 104. The other side of the spring 107 is fixedly connected to one end of the square groove 103. A transport pipe 108 is provided above the connecting pipe 102. An annular locking block 10 is fixedly connected to the outside of the transport pipe 108. 9. An arc-shaped locking block 110 is slidably connected to the outside of the transport pipe 108, and the arc-shaped locking block 110 is positioned above the annular locking block 109. By aligning the annular locking block 109 of the transport pipe 108 with the connecting pipe 102, the transport pipe 108 is pushed, and the annular locking block 109 compresses the limiting block 104, causing the limiting block 104 to push the sliding rod 105 to slide inside the square groove 103, compressing the spring 107. When the annular locking block 109 reaches the appropriate position, the spring 107 pushes the limiting block 104 to reset, fixing the annular locking block 109 and achieving locking. The arc-shaped locking block 110 will slide to the appropriate position to further tighten the connection and enhance the seal. By pushing the transport pipe 108 downward again, the arc-shaped locking block 110 slides downward. When it slides to the position where it abuts against the annular locking block 109, it compresses the limiting block 104, thereby allowing the transport pipe 108 to be removed from the connecting pipe 102 for easy replacement.

[0023] Please see Figures 3-6In this embodiment, the inclined surface of the annular locking block 109 and the inclined surface of the limiting block 104 have the same inclination angle. The same inclination angle ensures that the annular locking block 109 and the limiting block 104 can interact accurately and smoothly during contact and relative movement. When the annular locking block 109 reaches the locking position, the limiting block 104 with the same inclination angle can fit tightly with the annular locking block 109 and lock together to form a stable self-locking structure. Through the elastic force of the spring 107, the limiting block 104 tightly abuts against the annular locking block 109 to prevent the transport pipe 108 from moving or separating from the connecting pipe 102.

[0024] Please see Figures 5-6 In this embodiment, an installation plate 111 is fixedly connected inside the connecting pipe 102. A spring 112 is fixedly connected above the installation plate 111. A sealing ring 201 is fixedly connected above the spring 112. The sealing ring 202 is provided above the connecting pipe 102. When the transport pipe 108 is pushed into the connecting pipe 102, the sealing ring 201 is squeezed. After the transport pipe 108 is installed in a suitable position, the sealing ring 201 will abut against the transport pipe 108 by the action of the spring 112, maintaining good sealing performance. After the transport pipe 108 is connected to the connecting pipe 102, the sealing ring 202 is installed at the junction of the connecting pipe 102 and the transport pipe 108, and fits tightly with the transport pipe 108 and the connecting pipe 102 to enhance the sealing performance.

[0025] During operation, by aligning the annular locking block 109 of the transport pipe 108 with the connecting pipe 102, the transport pipe 108 is pushed, causing the annular locking block 109 to compress the limiting block 104. This causes the limiting block 104 to push the sliding rod 105 to slide inside the square groove 103, compressing the spring 107. When the annular locking block 109 reaches the appropriate position, the spring 107 pushes the limiting block 104 to reset, fixing the annular locking block 109 and achieving locking. The arc-shaped locking block 110 will slide to the appropriate position, further tightening the connection and enhancing the seal. By pushing the transport pipe 108 downward, the arc-shaped locking block 110 slides downward. When it slides to the position where it abuts against the annular locking block 109, it compresses the limiting block 104, thereby allowing the transport pipe 108 to be removed from the connecting pipe 102 for easy replacement. The same tilt angle ensures that the annular locking block 109 and the limiting block 104 are in contact and in relative motion. During the process, they can interact accurately and smoothly. When the ring-shaped locking block 109 reaches the locking position, the limiting block 104 with the same tilt angle can fit tightly with the ring-shaped locking block 109, locking each other to form a stable self-locking structure. Under the elastic force of the spring 107, the limiting block 104 tightly abuts against the ring-shaped locking block 109 to prevent the transport pipe 108 from moving or separating from the connecting pipe 102. When the transport pipe 108 is pushed into the connecting pipe 102, the sealing ring 201 is squeezed. After the transport pipe 108 is installed in the appropriate position, the sealing ring 201 will abut against the transport pipe 108 by the action of the spring 112, maintaining good sealing. After the transport pipe 108 is connected to the connecting pipe 102, the sealing ring 202 is installed at the junction of the connecting pipe 102 and the transport pipe 108, fitting tightly with the transport pipe 108 and the connecting pipe 102 to enhance the sealing.

[0026] Through the above steps, by aligning the annular locking block 109 of the transport pipe 108 with the connecting pipe 102, the transport pipe 108 is pushed, and the annular locking block 109 compresses the limiting block 104, causing the limiting block 104 to push the sliding rod 105 to slide inside the square groove 103, compressing the spring 107. When the annular locking block 109 reaches the appropriate position, the spring 107 pushes the limiting block 104 to reset, fixing the annular locking block 109 and achieving locking. The arc-shaped locking block 110 will slide to the appropriate position to further tighten the connection and enhance the seal. By pushing the transport pipe 108 downward, the arc-shaped locking block 110 slides downward. When it slides to the position where it abuts against the annular locking block 109, it compresses the limiting block 104, thereby allowing the transport pipe 108 to be removed from the connecting pipe 102 for easy replacement.
