Description

Technical Field

[0001] This utility model relates to the field of gas cylinder base technology, specifically to a gas cylinder base. Background Technology

[0002] Portable liquefied petroleum gas (LPG) cylinders are widely used in conjunction with portable tools such as flamethrowers and outdoor stoves due to their portability and high energy density. They are commonly used in outdoor work, camping, cooking, and DIY activities. To ensure the stability and safety of these cylinders during use or temporary storage, they should typically be placed upright on a dedicated cylinder base to prevent tipping, gas leaks, connector damage, or other safety accidents.

[0003] Currently, portable gas cylinders on the market, even those with the same nominal diameter, have different designs for the flange structure at the bottom. They are mainly divided into two types: the first type has a flange outer diameter larger than the outer diameter of the cylinder body, forming a protruding support edge; the second type has a flange outer diameter smaller than the outer diameter of the cylinder body, forming a concave transition section between the cylinder body and the flange.

[0004] For bases specifically designed for the first type of large-flange gas cylinder: the inner diameter of its mounting hole must be large enough to accommodate the large flange and potentially secure it with a snap-fit ​​mechanism. If a second type of small-flange gas cylinder is placed in such a base, the large gap between the cylinder body and the mounting hole prevents the base from effectively holding the cylinder, causing it to wobble within the base. This not only affects the stability of the connection with tools such as flamethrowers but also poses a risk of tipping over due to slight impacts. For bases specifically designed for the second type of small-flange gas cylinder: the inner diameter of its mounting hole usually closely matches the outer diameter of the cylinder body. However, because the outer diameter of the flange of the first type of gas cylinder is larger than this mounting hole, it cannot be inserted at all, rendering it unusable. Therefore, current gas cylinder bases have poor versatility. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gas cylinder base to solve the technical problem of poor versatility of gas cylinder bases in the existing technology.

[0006] To solve the above-mentioned technical problems, this utility model provides a gas cylinder base, comprising: The base body has a mounting hole on its upper surface. The mounting hole includes a first bottle hole and a second bottle hole arranged coaxially. The second bottle hole is located above the first bottle hole. The inner diameter of the second bottle hole is larger than the inner diameter of the first bottle hole and forms a first step surface between the second bottle hole and the first bottle hole. Several first elastic pieces that can deform radially are provided on the side wall of the mounting hole along the circumferential direction. A plurality of first limiting protrusions and a plurality of second limiting protrusions are provided on the inner end face of the first spring piece. Each first spring piece is provided with at least one first limiting protrusion and / or at least one second limiting protrusion. The inner end of each first limiting protrusion is located in the first bottle hole, and the inner end of each second limiting protrusion is located in the second bottle hole. The inner end of the second limiting protrusion is closer to the outer side of the base body than the inner end of the first limiting protrusion.

[0007] With the above structure, the gas cylinder base of this utility model has the following advantages: Both the first and second cylinder holes are designed for gas cylinders of the same diameter. The inner diameter of the first cylinder hole matches the outer diameter of the cylinder body, and the inner diameter of the second cylinder hole matches the outer diameter of the flange of the first type of large-flange gas cylinder. When a second type of small-flange gas cylinder is placed, the cylinder body passes through the second cylinder hole and enters the first cylinder hole. The outer wall of the cylinder body presses against the first limiting protrusion located in the first cylinder hole, forcing the first elastic piece to elastically deform outward. Its rebound force then grips the lower part of the cylinder body. The locking mechanism is located in the concave transition section between the cylinder body and the flange, achieving a stable fixation. When the first type of large flanged gas cylinder is placed, the cylinder body is inserted into the second cylinder hole. The large flange presses against the second limiting protrusion located in the second cylinder hole, forcing the first spring to elastically deform outward. The large flange falls into the second cylinder hole and is supported and limited by the first stepped surface. At this time, the second limiting protrusion is limited above the large flange, thereby fixing the gas cylinder. This allows the same gas cylinder base to adapt to and stably fix two types of gas cylinders of the same diameter with different bottom flange structures, improving the versatility of the gas cylinder base.

[0008] As an improvement, each first spring is provided with a first limiting protrusion and a second limiting protrusion. With this structure, each first spring has a dual limiting function, the structure is regular, the force is evenly distributed, and the structure is simplified. No matter what kind of gas cylinder it is adapted to, all the first springs can work together to participate in clamping and limiting, effectively preventing the gas cylinder from swaying or shaking in the base, and further enhancing the load-bearing stability and reliability of the base.

[0009] As an improvement, the mounting hole also includes a third bottle hole located above the second bottle hole and with an inner diameter larger than the second bottle hole. The third bottle hole is coaxially arranged with the second bottle hole, forming a second stepped surface between the third bottle hole and the second bottle hole. Several second elastic pieces that can deform radially are provided along the circumferential direction on the side wall of the third bottle hole. A third limiting protrusion is provided on the inner end face of the second elastic piece, and the inner end of the third limiting protrusion is located inside the third bottle hole. With this structure, the third bottle hole is used to install large-diameter large-flanged gas cylinders. The installation and limiting principle is the same as that of the first type of large-flanged gas cylinder, expanding the compatibility range of the gas cylinder base from two to three types, greatly improving the product's versatility and market adaptability. One set of bases can meet the needs of more complex and diverse usage scenarios.

[0010] As an improvement, the inner ends of the first, second, and third limiting protrusions are all arc-shaped, matching the outer diameter of the gas cylinder. With this structure, the arc-shaped inner end face increases the contact area between the limiting protrusion and the cylindrical gas cylinder body, making the clamping force distribution more uniform.

[0011] As an improvement, the sidewalls of the first and second bottle holes are provided with a number of first through grooves along the circumference, and each first through groove is provided with a first spring piece, the upper end of the first spring piece being located at the upper end of the first through groove. The sidewalls of the third bottle hole are provided with a number of second through grooves along the circumference, and each second through groove is provided with a second spring piece, the upper end of the second spring piece being located at the upper end of the second through groove.

[0012] As an improvement, several first spring clips and several second spring clips are equidistantly distributed along the circumference of the mounting hole; this structure improves the stability of the spring clips in limiting the gas cylinder.

[0013] As an improvement, the upper surfaces of the first, second, and third limiting protrusions are all inclined surfaces that slope downwards from the outside in. With this structure, the inclined surfaces act as guides, allowing the bottle body or flange to slide smoothly down the inclined surfaces and push the spring piece outwards, greatly reducing insertion resistance. This makes the installation of the gas cylinder very effortless and smooth, improving the user experience.

[0014] As an improvement, the lower end faces of the first limiting protrusion, the second limiting protrusion, and the third limiting protrusion are all inclined surfaces that slope from the outside inward and upward. With this structure, the inclined surfaces also play a guiding role when disassembling the bottle body, which can smoothly push the spring piece outward during the process of the gas cylinder rising, making disassembly easier and improving the user experience.

[0015] As an improvement, the base body has several support components evenly spaced along the circumference at its bottom. Each support component includes a support member, one end of which is rotatably connected to the bottom of the base body. By rotating the support member, the support member can be folded into or unfolded outside the base body. With this structure, the retractable support member significantly increases the contact area between the base and the placement surface, forming a stable support surface and greatly improving the stability of the base on the horizontal plane, thus enhancing its anti-tipping ability. When not in use, the support member can be folded up to reduce the overall volume, making it convenient for packaging, transportation, and storage, thus balancing stability and portability.

[0016] As an improvement, each support component also includes a limiting member connected to the bottom of the base body. One end of the support component is located above the limiting member. The support component is U-shaped, with first protrusions on both sides of the inner end of the limiting member and second protrusions on both sides of the outer end. The maximum distance between the two first protrusions and the maximum distance between the two second protrusions are both greater than the distance between the two opposite inner walls of the support component, and the distance between the two opposite inner walls of the support component is greater than the width of the limiting member. With this structure, the cooperation design between the limiting member and the U-shaped support component, through the first and second protrusions, achieves precise positioning and self-locking function of the support component in both unfolding and retracting positions. This structure ensures that the support component can be stably supported when unfolded and will not accidentally fold back during use, and can also be stably fixed when retracted and will not unfold arbitrarily. The structure is simple and reliable, and the operation feel is clear, further improving the practicality of the product. Attached Figure Description

[0020] The following is a detailed description of a gas cylinder base according to the present invention, with reference to the accompanying drawings.

[0021] like Figures 1 to 2 As shown, a gas cylinder base includes a base body 1, a plurality of first limiting protrusions 6 and a plurality of second limiting protrusions 7. The upper end face of the base body 1 is provided with a mounting hole, which includes a first bottle hole 2 and a second bottle hole 3 coaxially arranged. The second bottle hole 3 is located above the first bottle hole 2. The inner diameter of the second bottle hole 3 is larger than the inner diameter of the first bottle hole 2 and forms a first step surface 4 between the second bottle hole 3 and the first bottle hole 2. A plurality of first elastic pieces 5 that can be deformed radially are provided on the side wall of the mounting hole along the circumferential direction. Radial deformation means that when the first elastic piece 5 is deformed, its position in the radial direction changes.

[0022] A plurality of first limiting protrusions 6 and a plurality of second limiting protrusions 7 are all disposed on the inner end face of the first spring piece 5. Each first spring piece 5 is provided with at least one first limiting protrusion 6 and / or at least one second limiting protrusion 7. Specifically, the first spring piece 5 may only be provided with the first limiting protrusion 6 or only with the second limiting protrusion 7, or it may simultaneously be provided with the first limiting protrusion 6 and the second limiting protrusion 7. In this embodiment, for example... Figure 1 As shown, each first spring piece 5 is provided with a first limiting protrusion 6 and a second limiting protrusion 7, and the sidewalls of the first bottle hole 2 and the second bottle hole 3 are provided with a plurality of first through grooves 12 along the circumferential direction. Each first through groove 12 is provided with a first spring piece 5. The upper end of the first spring piece 5 is located at the upper end of the first through groove 12. The first spring piece 5 rotates with its upper end as the axis to achieve radial deformation.

[0023] The inner end of each first limiting protrusion 6 is located inside the first bottle hole 2, and the inner end of each second limiting protrusion 7 is located inside the second bottle hole 3. The inner end of the first limiting protrusion 6 being located inside the first bottle hole 2 means that the inner end of the first limiting protrusion 6 is located inside the first bottle hole 2 in the axial direction, and is closer to the inner side relative to the inner wall of the first bottle hole 2 in the radial direction. The inner side refers to the center of the mounting hole. The same applies to the second limiting protrusion 7, and the inner end of the second limiting protrusion 7 is closer to the outer side of the base body 1 than the inner end of the first limiting protrusion 6. The first bottle hole 2 and the second bottle hole 3 are both for gas cylinders of the same diameter. The inner diameter of the first bottle hole 2 matches the outer diameter of the cylinder body, and the inner diameter of the second bottle hole 3 matches the outer diameter of the flange of the first type of large flanged gas cylinder. The inner ends of the first limiting protrusion 6 and the second limiting protrusion 7 are both arc-shaped and match the outer diameter of the gas cylinder. The inner end of the second limiting protrusion 7 and the inner wall of the first bottle hole 2 are in contact with the cylinder body. Therefore, the inner diameter of the second limiting protrusion 7 and the inner diameter of the first bottle hole 2 are preferably the same.

[0024] When the second type of small flanged gas cylinder is placed, the cylinder body passes through the second cylinder hole 3 and enters the first cylinder hole 2. The outer wall of the cylinder body presses against the first limiting protrusion 6 located in the first cylinder hole 2, forcing the first elastic piece 5 to elastically deform outward. Its rebound force then grips the lower part of the cylinder body, achieving a stable fixation. Specifically, the first limiting protrusion 6 engages with the concave transition section between the cylinder body and the flange. Furthermore, since the inner diameter of the second limiting protrusion 7 is the same as the inner diameter of the first cylinder hole 2, the second limiting protrusion 7 also abuts against the outer wall of the cylinder body at this time. To further improve stability, when the first type of large-flange gas cylinder is placed, the cylinder body is inserted into the second cylinder hole 3. The large flange presses against the second limiting protrusion 7 located in the second cylinder hole 3, forcing the first spring piece 5 to elastically deform outward. The large flange falls into the second cylinder hole 3 and is supported and limited by the first step surface 4. At this time, the second limiting protrusion 7 is limited above the large flange, thereby fixing the gas cylinder. This achieves the same gas cylinder base to adapt to and firmly fix two types of gas cylinders of the same diameter with different bottom flange structures, improving the versatility of the gas cylinder base.

[0025] In addition, the mounting hole also includes a third bottle hole 8 located above the second bottle hole 3 and with an inner diameter larger than the second bottle hole 3. The third bottle hole 8 is coaxially arranged with the second bottle hole 3, and a second step surface 9 is formed between the third bottle hole 8 and the second bottle hole 3. Several second spring pieces 10 that can be deformed radially are provided on the side wall of the third bottle hole 8 along the circumferential direction. A third limiting protrusion 11 is provided on the inner end face of the second spring piece 10, and the inner end of the third limiting protrusion 11 is located inside the third bottle hole 8.

[0026] The third bottle hole 8 is used to install large-diameter, large-flange gas cylinders. The installation and limiting principle is the same as that of the first type of large-flange gas cylinder, which expands the compatibility range of the gas cylinder base from two to three types, greatly improving the product's versatility and market adaptability. One set of bases can meet the needs of more complex and diverse usage scenarios. Similarly, the inner end of the third limiting protrusion 11 is an arc shape that matches the outer diameter of the gas cylinder. The side wall of the third bottle hole 8 is provided with several second through grooves 13 along the circumference. Each second through groove 13 is provided with a second spring piece 10. The upper end of the second spring piece 10 is located at the upper end of the second through groove 13.

[0027] like Figure 1 As shown, a number of first spring pieces 5 and a number of second spring pieces 10 are equidistantly distributed along the circumference of the mounting hole. In this embodiment, there are three first spring pieces 5 and three second spring pieces 10.

[0028] The upper surfaces of the first limiting protrusion 6, the second limiting protrusion 7, and the third limiting protrusion 11 are all inclined surfaces that slope downwards from the outside in, and the lower surfaces of the first limiting protrusion 6, the second limiting protrusion 7, and the third limiting protrusion 11 are all inclined surfaces that slope upwards from the outside in. The inclined surfaces act as guides, allowing the cylinder body or flange to slide smoothly down the inclined surfaces during cylinder installation and to push the spring clip outwards. During cylinder removal, the spring clip can be pushed outwards as the cylinder body rises, significantly reducing insertion and removal resistance. This makes cylinder installation and removal operations very effortless and smooth, improving the user experience.

[0029] In addition, such as Figure 2As shown, a plurality of support components 14 are equidistantly arranged along the circumferential direction at the bottom end of the base body 1. Each support component 14 includes a support member 141, one end of which is rotatably connected to the bottom end of the base body 1. By rotating the support member 141, the support member 141 can be folded into the base body 1 or unfolded outside the base body 1. Furthermore, each support component 14 also includes a limiting member 142, which is connected to the bottom end of the base body 1. One end of the support member 141 is located above the limiting member 142. The support member 141 is U-shaped. The bottom end of the base body 1 is also provided with a clearance groove for the support member 141 to enter when it is unfolded. The inner ends of the limiting member 142 are provided with first protrusions 15 on both sides, and the outer ends of the limiting member 142 are provided with second protrusions 15 on both sides. In this embodiment, both the first protrusion 15 and the second protrusion 16 are hemispherical. The maximum distance between the two first protrusions 15 and the maximum distance between the two second protrusions 16 are both greater than the distance between the two opposing inner walls of the support member 141. The distance between the two opposing inner walls of the support member 141 is greater than the width of the limiting member 142. When the support member 141 rotates to the unfolded state, the support member 141 undergoes a slight deformation and passes over the two second protrusions 16 to be located above the limiting member 142, and the two second protrusions 16 prevent the support member 141 from retracting. When the support member 141 rotates to the retracted state, the support member 141 undergoes a slight deformation and passes over the two first protrusions 15 to be located above the limiting member 142, and the two first protrusions 15 prevent the support member 141 from unfolding.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiment. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
