Description

Technical Field

[0001] This utility model relates to the field of gas cylinder support devices, and in particular to a gas cylinder base. Background Technology

[0002] In the use and storage of gas cylinders, the cylinder base plays a crucial role. Gas cylinder bases are generally divided into mobile cylinder bases with wheels and fixed cylinder bases. Fixed cylinder bases not only stably support the gas cylinders, ensuring they remain upright in various environments and preventing tipping and accidents, but also protect the bottom of the cylinders from wear and impacts to a certain extent.

[0003] Commercially available fixed gas cylinder bases have the following drawbacks: Traditional gas cylinder bases use a one-piece design, which results in a large size and weight in order to maintain the stability of the gas cylinder using its own weight. This takes up a lot of space during transportation and storage, making them inconvenient to carry and store.

[0004] In view of this, the present invention proposes a gas cylinder base to address the shortcomings of the prior art. Summary of the Invention

[0005] To overcome the shortcomings of the aforementioned technologies, this utility model provides a gas cylinder base with foldable support legs. During the support of the gas cylinder, the support legs can be flipped and extended to improve the support effect. The support legs can also be folded and stored within the receiving cavity, reducing the space occupied by the gas cylinder base. To achieve the above objectives, this utility model adopts the following technical solution: A gas cylinder base includes a base body with a mounting groove on the top that matches the outer diameter of the gas cylinder. The bottom of the base body has a receiving cavity with at least two foldable legs evenly arranged around the circumference of the receiving cavity. Each foldable leg includes a locking plate fixedly installed in the receiving cavity and a support leg hinged to the locking plate. The support leg can be flipped out or retracted into the receiving cavity. The locking plate has a buckle structure for temporarily locking the support leg in the extended or retracted state.

[0006] As a preferred technical solution, the support foot is a continuous structure formed by bending a metal rod. The support foot is hollow in the middle, closed at one end and open at the other end. The support foot includes two extensions extending outward from the receiving cavity. The ends of the two extensions extending out of the receiving cavity are connected by a bending part to form a closed structure. The other end of the extension is provided with a hinge shaft. Both sides of the card plate are provided with hinge holes for connecting with the hinge shaft.

[0007] As a preferred technical solution, the distance between the two extensions and the width between the two sides of the card plate are adapted. The buckle structure includes a first protrusion and a second protrusion disposed on the side of the card plate, and the height of the buckle structure is lower than the hinge hole. The first protrusion is close to the center of the base body and is used to temporarily lock the extension in the storage state; the second protrusion is close to the outer edge of the base body and is used to temporarily lock the extension in the extended state.

[0008] As a preferred technical solution, the surfaces of the first protrusion and the second protrusion are both arc surfaces.

[0009] As a preferred technical solution, the card plate has a buckle structure on both sides, which is used to temporarily lock the corresponding extension.

[0010] As a preferred technical solution, the bottom outer edge of the base body is provided with multiple openings for the extension to pass through.

[0011] As a preferred technical solution, the receiving cavity is provided with a connecting rod, the connecting rod is provided with a threaded hole, the clamping plate is provided with a countersunk hole, and the threaded hole and the countersunk hole are connected by screws.

[0012] As a preferred technical solution, a plurality of first reinforcing ribs are evenly provided on the inner side of the mounting groove, and the first reinforcing ribs are used to fit tightly against the side of the gas cylinder.

[0013] As a preferred technical solution, the mounting groove is provided with an annular step around its inner side. The inner diameter of the annular step is adapted to the annular seat at the bottom of the gas cylinder, and the inner circle of the annular step is used to place the annular seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The base body of this utility model has a receiving cavity at the bottom, and at least two foldable support legs are evenly arranged around the circumference of the receiving cavity. The support legs can be flipped out or stored in the receiving cavity according to actual needs. During the process of supporting the gas cylinder, the support legs can be flipped out to improve the support effect of the gas cylinder base. The support legs can also be folded and stored in the receiving cavity to reduce the space occupied by the gas cylinder base and facilitate the storage and transportation of the gas cylinder base.

[0015] 2. The pallet also features a snap-fit ​​structure that supports the legs in either extended or retracted positions, enhancing structural stability.

[0016] 3. Multiple first reinforcing ribs are evenly distributed on the inner side of the mounting groove to ensure close contact with the side of the gas cylinder and enhance the mechanical strength of the base body. A ring-shaped step is provided around the inner side of the mounting groove, with the inner diameter matching the ring-shaped seat at the bottom of the gas cylinder. This allows for better placement of the ring-shaped seat, enhances the compatibility between the base and the gas cylinder, effectively prevents the gas cylinder from shaking or shifting, and provides more stable and reliable support for the gas cylinder.

Detailed Implementation

[0018] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art: Reference Figures 1-5 This utility model provides an embodiment of a gas cylinder base.

[0019] A type of gas cylinder base, such as Figure 1 As shown, the system includes a base body 1. The top of the base body 1 has a mounting groove 11 that matches the outer diameter of the gas cylinder 4, and the bottom of the base body 1 has a receiving cavity 12. The receiving cavity 12 is evenly provided with four foldable legs around its circumference. Each foldable leg includes a locking plate 2 fixedly installed in the receiving cavity 12 and a support leg 3 hinged to the locking plate 2. The support leg 3 can be flipped out or retracted into the receiving cavity 12. The locking plate 2 has a buckle structure for temporarily locking the support leg 3 to maintain its extended or retracted state.

[0020] like Figure 3 As shown, the support leg 3 is a continuous structure formed by bending a metal rod, possessing high mechanical strength and a simple structure. The support leg 3 has a hollow center, one end closed, and the other end open. The support leg 3 includes two extensions 31 extending outward from the receiving cavity 12. The ends of the two extensions 31 extending out of the receiving cavity 12 are connected by a bending part 32 to form a closed structure. The other end of the extension 31 is provided with a hinge shaft 33. Both sides of the clamping plate 2 are provided with hinge holes 21 for connecting with the hinge shaft 33, allowing the support leg 3 to rotate relative to the clamping plate 2 around the hinge shaft 33.

[0021] The distance between the two extensions 31 and the width between the two sides of the card plate 2 are adapted so that the two extensions 31 are respectively on the two outer sides of the card plate 2. The latching structure includes a first protrusion 22 and a second protrusion 23 provided on the side of the card plate 2, and the height of the latching structure is lower than the hinge hole 21. The first protrusion 22 is close to the center of the base body 1, and the second protrusion 23 is close to the outer edge of the base body 1.

[0022] In this embodiment, the card plate 2 is made entirely of plastic, and its hardness is less than that of the support foot 3. When the support foot 3 rotates outward around the hinge shaft 33 into the receiving cavity 12, the extension 31 contacts the second protrusion 23. Since the surface of the second protrusion 23 is an arc surface, the extension 31 can smoothly slide above the second protrusion 23. The second protrusion 23 is located below the extension 31, preventing the extension 31 from falling down, and the support foot 3 can remain extended.

[0023] When the support leg 3 rotates around the hinge shaft 33 into the receiving cavity 12, during this process, the extension 31 slides along the surface of the second protrusion 23 to below the second protrusion 23, and the extension 31 disengages from the second protrusion 23. Then the support leg 3 rotates again, and the extension 31 contacts the first protrusion 22. The surface of the first protrusion 22 is an arc surface, which allows the extension 31 to slide smoothly above the first protrusion 22. The first protrusion 22 is located below the extension 31, preventing the extension 31 from falling down, and the support leg 3 can remain in a folded and stored state.

[0024] The card plate 2 has a buckle structure on both sides, which is used to temporarily lock the corresponding extension part 31. This ensures that the two extension parts 31 are locked and supported, further enhancing the stability and reliability of the structure and ensuring that the support foot 3 remains stable in both states.

[0025] The base body 1 has multiple openings 13 on its bottom outer edge for the extension 31 to pass through, so that the support leg 3 can pass smoothly when it is flipped out and retracted. At the same time, the openings 13 are slightly larger than the diameter of the extension 31, which can limit the extension 31.

[0026] The receiving cavity is provided with a connecting rod 14, the connecting rod 14 is provided with a threaded hole 141, the clamping plate 2 is provided with a countersunk hole 24, and the threaded hole 141 and the countersunk hole 24 are connected by a screw 25, so that the clamping plate 2 is fixedly connected to the base body 1.

[0027] Multiple first reinforcing ribs 15 are evenly provided on the inner side of the mounting groove 11, which not only enhance the mechanical strength of the base body 1, but also allow the first reinforcing ribs 15 to fit tightly against the side of the gas cylinder 4, making the connection between the gas cylinder 4 and the gas cylinder base tight.

[0028] The mounting groove 11 has an annular step 16 around its inner side. The inner diameter of the annular step 16 is adapted to the annular base 41 at the bottom of the gas cylinder 4, which can better place the annular base 41, enhance the compatibility between the base and the gas cylinder 4, effectively prevent the gas cylinder 4 from shaking and shifting, and provide more stable and reliable support for the gas cylinder 4. The inner wall of the annular step 16 is provided with a second reinforcing rib 161 for tightly fitting the annular base 41.

[0029] The top of the base body 1 is also provided with a slot 17 for placing the igniter.

[0030] In this embodiment, slot 17 is ignored, and the gas cylinder base has a centrally symmetrical three-dimensional geometric structure, which ensures that the multiple foldable legs are evenly distributed circumferentially. In other embodiments, the number of foldable legs is no less than two to ensure stable support.

[0031] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
