Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, and in particular to a flattening sealing device for gas cylinder filling pipelines. Background Technology

[0002] A certain type of gas cylinder needs to be filled with high-pressure gas. After filling, the filling pipeline on the cylinder needs to be sealed to ensure that the gas does not leak and remains in the cylinder. Current sealing processes require flattening the filling pipeline to achieve a seal; however, when the filling pipeline is compressed into a flattened oval shape, the compressed area extends infinitely to both sides, easily damaging the pipeline and causing gas leakage, resulting in an unreliable seal. This poses reliability and safety risks during subsequent handling and storage; these defects are problems that urgently need to be solved by those skilled in the art. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model discloses a flattening and sealing device for gas cylinder filling pipeline.

[0004] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0005] A flattening and sealing device for a gas cylinder filling pipeline includes an upper clamping body, a lower clamping body, and bolts. The upper clamping body has a boss at its bottom, and the lower clamping body has a cavity at its top that corresponds to and fits the boss. The bottom of the boss and the bottom of the cavity are respectively provided with rectangular grooves for compressing the gas cylinder filling pipeline into a rectangular shape. The cavity wall is provided with limiting slots at both ends of the rectangular grooves for limiting the gas cylinder filling pipeline. Bolts are installed on both sides of the upper clamping body corresponding to the boss to clamp the upper and lower clamping bodies together.

[0006] Preferably, the lower clamp has a threaded hole corresponding to the bolt at the same position, and the upper clamp has a light hole corresponding to the bolt at the same position, allowing the bolt to move through.

[0007] Preferably, the boss is provided with relief grooves at both ends of its rectangular groove to prevent damage to the gas cylinder filling pipeline, and the bottom of the relief groove and the limiting groove are inclined.

[0008] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0009] This utility model discloses a flattening and sealing device for a gas cylinder filling pipeline. It has a simple structure, is easy to assemble, and has a low production cost. Rectangular grooves are respectively provided at the bottom of the boss and the bottom of the cavity to compress the gas cylinder filling pipeline into a rectangular shape. During the clamping process, the upper and lower surfaces of the gas cylinder filling pipeline gradually come together due to the force and are gradually flattened. Due to the restriction of the rectangular grooves, the gas cylinder filling pipeline cannot extend infinitely to both sides during the flattening process. When the bottom of the boss contacts the bottom of the cavity, the gas cylinder filling pipeline is compressed into a rectangular shape that corresponds to the rectangular groove, achieving a sealing state and ensuring the sealing effect.

[0010] This utility model further provides relief grooves at both ends of the boss corresponding to its rectangular groove to prevent damage to the gas cylinder filling pipeline. The bottom of the relief groove and the limiting groove are both inclined. That is, during the clamping process of the upper clamp and the lower clamp, the pipe body of the gas cylinder filling pipeline located at the relief groove and the limiting groove will not be squeezed, thereby preventing damage to the non-sealed section of the gas cylinder filling pipeline.

[0016] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation.

[0017] Example 1, in conjunction with Appendix Figures 1-4 A flattening and sealing device for a gas cylinder filling pipeline, comprising an upper clamping body 1, a lower clamping body 2, and bolts 3; as shown in the attached figure. Figure 3 As shown, the bottom of the upper clamping body 1 is provided with a boss 4; as attached Figure 4As shown, the lower clamping body 2 has a cavity 5 at the top that corresponds to and fits the boss 4. Rectangular grooves 6 are respectively provided at the bottom of the boss 4 and the bottom of the cavity 5 to compress the gas cylinder filling pipe into a rectangular shape, as shown in the attached diagram. Figure 2 As shown, when in use, the upper clamp 1 and the lower clamp 2 are clamped together. During the clamping process, the upper and lower surfaces of the gas cylinder filling pipe gradually come together due to the force. After being flattened, the upper and lower surfaces of the gas cylinder filling pipe are completely and tightly fitted together to achieve a seal. Due to the restriction of the rectangular groove 6, the gas cylinder filling pipe cannot extend infinitely to both sides during the flattening process. When the bottom of the protrusion 4 contacts the bottom of the cavity 5, the gas cylinder filling pipe is squeezed into a rectangular shape that corresponds to the rectangular groove 6, achieving a sealed state.

[0018] It should be noted that the boss 4 is provided with relief grooves 8 at both ends of its rectangular groove 6 to prevent damage to the gas cylinder filling pipeline. The bottom of the relief grooves 8 and the limiting grooves 7 are both inclined. That is, during the clamping process of the upper clamping body 1 and the lower clamping body 2, the pipe body of the gas cylinder filling pipeline located at the relief grooves 8 and the limiting grooves 7 will not be squeezed, thereby preventing damage to the non-sealed section of the gas cylinder filling pipeline.

[0019] The cavity wall of the concave cavity 5 is provided with limiting slots 7 at both ends of the rectangular groove 6 for limiting the gas cylinder filling pipeline. That is, before the upper clamping body 1 and the lower clamping body 2 are clamped, the gas cylinder filling pipeline can be placed in the limiting slots 7, so that the gas cylinder filling pipeline can be aligned with the rectangular groove 6.

[0020] Both sides of the upper clamping body 1 corresponding to the boss 4 are equipped with bolts 3 for clamping the upper clamping body 1 and the lower clamping body 2, that is, the upper clamping body 1 and the lower clamping body 2 can be clamped by tightening the two bolts 3; as needed, the lower clamping body 2 is provided with a threaded hole corresponding to the bolt 3 at the position of the bolt 3, and the upper clamping body 1 is provided with a light hole that allows the bolt 3 to move through, that is, the bolt 3 and the threaded hole of the lower clamping body 2 are threadedly connected, and the upper clamping body 1 and the lower clamping body 2 are clamped by tightening the two bolts 3.

[0021] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
