Technology Field

[0001] The present invention relates to a foldable stand for a high-pressure gas cylinder, and more specifically, to a foldable stand for a high-pressure gas cylinder that can safely support a high-pressure gas cylinder and allows for easy storage when not in use by folding the upper and lower support arms, and is provided with a fixing band that wraps around the outer periphery of the high-pressure gas cylinder and is provided with a pair of upright poles that are connected to both sides of the fixing band and extended, an upper transfer ring connected to the outer periphery of the upright poles so as to be movable up and down, a lower fixing ring connected to the lower outer periphery of the upright poles, upper and lower support arms connected to the upper transfer ring and lower fixing ring so as to rotate and unfold or fold when the upper transfer ring moves up and down, and a support foot connected to a central hinge end to allow the upper and lower support arms to rotate. Background Technology

[0002] Generally, high-pressure gas containers accommodate household high-pressure gases such as LPG, or laboratory or industrial high-pressure gases such as nitrogen or carbon dioxide, and the said high-pressure gases are filled in a gaseous or liquid state and supplied to consumers.

[0003] Such high-pressure gas containers or cylinders are stored in isolated areas or placed in convenient locations to ensure user safety. However, high-pressure gas cylinders are tall and prone to tipping over, and if they do, components such as gas inlet / outlet valves can be easily damaged; consequently, various technologies are being proposed to prevent this.

[0004] As prior art related to this, Registered Patent Publication No. 10-2118301 (Registration date: May 27, 2020) discloses a "mounting gas cylinder fixing device."

[0005] The above prior art includes, as shown in FIG. 1, a plurality of buttons (30) formed in one direction on the upper surface of a mounting bracket (10) and pressed by the weight of the gas cylinder (T) when mounted thereon, a fixed arm (20) hinge-coupled to one end of a connecting frame (40) that rotates when the button (30) is pressed, and a spring that elastically couples the fixed arm (20) to the connecting frame (40); when the gas cylinder (T) is mounted on the mounting bracket (10), the button (30) is pressed by the weight of the gas cylinder (T) and the connecting frame (40) rotates in a first direction so that the other end of the fixed arm (20) presses the gas cylinder (T); and when the gas cylinder (T) is lowered from the mounting bracket (10), the connecting frame (40) rotates in a second direction opposite to the first direction by the weight of the fixed arm (20) so that the The button (30) moves upward, thereby safely mounting the gas cylinder (T).

[0006] However, the aforementioned conventional technology had a problem in that when the gas cylinder (T) was placed on the upper part of the button, the end of the fixed arm (20) rotated and struck the outer periphery of the gas cylinder (T), so when placing the gas cylinder, the user had to be careful of safety and slowly move the gas cylinder (T) to the upper part of the stand to place it.

[0007] The "safety gas cylinder" disclosed in another type of technology, Public Utility Model Publication No. 95-23608 (August 23, 1995), is characterized by reinforcing stability by bonding an elastic cushioning expansion to the outer periphery of the gas cylinder with double-sided tape, and mitigating shock and preventing noise by attaching an elastic cushioning plate to the bottom of the gas cylinder.

[0008] However, since the aforementioned conventional technology consists of a standard gas cylinder with a support protruding from the bottom surface, there was a problem in that the gas cylinder could easily tip over due to external impact in outdoor workplaces with uneven ground. The problem to be solved

[0009] The present invention was created to solve the problems of the prior art as described above, and the objective of the present invention is to provide a foldable stand for a high-pressure gas cylinder that allows the high-pressure gas cylinder to be safely and conveniently mounted by folding the upper support arm and lower arm connection part to reduce volume for storage when not in use, and unfolding the upper support arm and lower arm connection part to stably support the support foot on the ground. This is achieved by having a fixed band provided at the top that wraps around the outer circumference of the high-pressure gas cylinder and is locked by a locking means, and an upper support arm connected to an upper transfer ring that moves up and down on an upright pole connected to both sides of the fixed band, and a lower support arm connected at a central hinge end, which is rotatably connected to a lower fixed ring on the lower outer circumference of the upright pole. means of solving the problem

[0011] The upper support arm and the lower support arm are characterized by folding or unfolding onto the upright pole during the up and down movement of the upper transfer ring.

[0012] The above-described fixing band is characterized by having a pair of opposing circumferential bands, a band hinge connected between the circumferential bands to allow the circumferential bands to unfold or fold to both sides, and a locking means for locking or unlocking the state in which the circumferential bands wrap around the circumferential of a high-pressure gas container.

[0013] The support foot is provided with an upper coupling member rotatably coupled to the central hinge end and a support plate coupled to the lower end of the upper coupling member, and the support foot is characterized by being rotated so that the lower surface of the support plate faces the ground direction when the upper transfer ring is transferred downward.

[0014] The upper transfer ring is provided in a 'C' shape to facilitate connection to the upright pole, and the pair of arm connecting parts are formed to protrude outwardly at a predetermined angle from the outer surface of the upper transfer ring, and are characterized by having a hinge connecting hole at the outer end to which the upper support arm is connected.

[0015] The lower arm connecting portion is formed to protrude outward from the outer circumference of the lower fixing ring and extends in correspondence with the arm connecting portion, and is characterized by having a lower hinge connecting hole at the outer end of the lower arm connecting portion to which the lower supporting arm is coupled.

Specific details for implementing the invention

[0022] Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0023] The foldable stand for a high-pressure gas cylinder according to the present invention is a foldable stand for a high-pressure gas cylinder (T) that enhances safety and ease of use by wrapping around and mounting the perimeter of the high-pressure gas cylinder (T) used at the work site, as shown in FIGS. 2 to 6.

[0024] The foldable stand of the present invention comprises a fixing band (10) that wraps around the outer circumference of the high-pressure gas container (T), a pair of upright poles (20) that are connected to and extended from both outer circumferences of the fixing band (10), an upper transfer ring (30) that is connected to the outer circumference of the upright poles (20) so as to be movable up and down and has a pair of female connecting parts (31) on its outer circumference, a lower fixing ring (40) that is connected to the lower outer circumference of the upright poles (20) and has a pair of female connecting parts (41) on its outer circumference, an upper support arm (50) that is rotatably connected to the female connecting parts (31), a lower support arm (60) that has one end rotatably connected to the lower female connecting parts (41), a central hinge end (70) to which the upper support arm (50) and the lower support arm (60) are hinge-connected, and a member connected to the central hinge end (70). A support foot (80) that is supported on the ground when the upper support arm (50) and the lower support arm (60) are unfolded is provided. As shown in FIG. 4 or FIG. 6, the upper transfer ring (30) may further be provided with a hand bolt, which is a locking means for fixing the position moved from the upright pole (20) in the center.

[0025] One side of the upper support arm (50) and the lower support arm (60) is hinge-connected to the arm connection part (31) and the lower arm connection part (41), and the other side of the upper support arm (50) and the lower support arm (60) is connected to the central hinge end (70), so that when the upper support arm (50) is moved up and down along the upper transfer ring (30), the central hinge end (70) is unfolded or folded, thereby rotating the lower support arm (60) up and down.

[0026] That is, the upper support arm (50) and the lower support arm (60) are folded or unfolded on the upright pole (20) when the upper transfer ring (30) is moved up and down.

[0027] Meanwhile, the fixed band (10) is provided with a pair of opposing circumferential bands (11), a band hinge (12) connected between the circumferential bands (11) so that the circumferential bands (11) can be spread out or folded to both sides, and a locking means (13) for locking or unlocking the state in which the circumferential bands (11) wrap around the circumferential of a high-pressure gas container (T).

[0028] Here, it is preferable that the circumferential band (11) be provided in an arc shape that adheres closely to the outer circumference of the high-pressure gas container, and it is preferable that the band hinge (12) be provided as a conventional hinge with a wing portion formed to fit the outer circumference of the circumferential band (11) and secured by screws or welding. Additionally, the locking means (13) is configured to securely fix the high-pressure gas container by fixing the circumferential band (11) in a closed state centered around the band hinge (12), and can be provided as various types of locking devices such as a conventional buckle type or a swivel hook.

[0029] Meanwhile, the support foot (80) is provided with an upper coupling member (81) rotatably coupled to the central hinge end (70) and a support plate (82) coupled to the lower end of the upper coupling member (81), and the support foot (80) is rotated so that the lower surface of the support plate (82) is supported on the ground when the upper transfer ring (30) is transferred downward.

[0030] Additionally, the upper transfer ring (30) is provided in a 'C' shape to facilitate connection to the upright pole (20). The 'C'-shaped upper transfer ring (30) allows for relatively easy up-and-down movement along the outer periphery of the upright pole (20).

[0031] The above pair of arm connecting parts (31) are formed to protrude outwardly at a predetermined angle from the outer surface of the upper transfer ring (30), and a hinge connecting hole (31a) is provided at the outer end to which the upper support arm (50) is connected. A connecting hole corresponding to the hinge connecting hole (31a) is also provided at one end of the upper support arm (50).

[0032] Additionally, the lower arm connecting part (41) is formed to protrude outward from the outer circumference of the lower fixing ring (40) and extends in correspondence with the arm connecting part (31), and a lower hinge connecting hole (41a) is provided at the outer end of the lower arm connecting part (41) to which the lower supporting arm (60) is coupled.

[0033] The upper support arm (50) and lower support arm (60) are preferably made of a plate-shaped alloy material to facilitate folding, but are not necessarily limited thereto.

[0035] The operation of the foldable stand for a high-pressure gas container according to the present invention, configured as described above, is as follows.

[0036] As shown in FIGS. 2 to 6, the foldable stand for a high-pressure gas cylinder of the present invention supports the high-pressure gas cylinder (T) safely at a work site or storage area by moving the upper transfer ring (30), which is connected to the upper support arm (50), downwards, thereby supporting the support foot (80) coupled to the central hinge end (70) on the ground. Afterward, the high-pressure gas cylinder (T) is moved inside the fixing band (10), and then the locking means (13), which are coupled to both ends of the circumference band (11), are locked to fix and mount the high-pressure gas cylinder (T). The upper transfer ring (30) is provided on each of the two upright poles (20).

[0037] One end of the above fixing band (10) can be locked or unlocked through a locking means (13) to wrap around and secure the upper central circumference of the high-pressure gas container (T).

[0038] Meanwhile, the upper support arm (50), which has one end connected to the upper transfer ring (30), is connected to one end of the lower support arm (60) at the central hinge end (70).

[0039] When the upper transfer ring (30) is transferred downward along the upright pole (20), the upper support arm (50) and the lower support arm (60) are further spread outward, and the diameter of the central hinge section (70) becomes larger. Afterwards, the support foot (80) of the central hinge section (70) is supported on the ground and used.

[0040] And, when the upper transfer ring (30) is transferred upward along the upright pole (20), the upper support arm (50) is moved upward and the end of the lower support arm (60) is also moved upward, and when the upper transfer ring (30) is positioned at the top, the upper support arm (50) and the lower support arm (60) are extended in the longitudinal direction along the upright pole (20) in a state where they are spread out 180 degrees at the central hinge end (70).

[0041] In this way, the foldable stand for a high-pressure gas container of the present invention allows the upper support arm (50) and the lower support arm (60) to unfold or fold at the central hinge end (70) when the upper transfer ring (30) is moved up and down, making storage and use easy, and the fixing band (10) equipped with a pair of circumferential bands (11) prevents the high-pressure gas container (T) from tipping over, thereby enabling safe use.

[0042] The present invention is not limited to the specific preferred embodiments described above, and anyone with ordinary knowledge in the art to which the invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims, and such modifications will be within the scope of the claims.
