Description

Technical Field

[0001] The utility model relates to the technical field of gas storage cylinders, in particular to an acetylene storage cylinder. Background Technique

[0002] An acetylene cylinder is a container for storing and transporting acetylene. The main part of the acetylene cylinder is a cylindrical welded cylinder body rolled from high-quality carbon steel or low-alloy steel, but the overall is a long strip structure. During daily use and handling, the acetylene cylinder will inevitably fall over. If the valve at the top of the acetylene cylinder is hit, the root of the valve will be stressed and bent, which is prone to leakage. And acetylene is poisonous, and leakage is extremely dangerous.

[0003] Such as Figure 5 As shown, a protective cover is installed at the top of the existing acetylene cylinder, and a notch for extending the valve inlet and outlet is provided on one side of the protective cover. The valve at the top of the acetylene cylinder and the cylinder are fastened by a threaded connection. For better sealing, sealing tape is wound around the threaded surface of the valve, and then the valve is tightened on the top of the cylinder. However, the threaded connection method cannot ensure that the valve is in a specific position during the tightening process. Because of factors such as different numbers of turns of the wound sealing tape and machining errors of the threads, the valve inlet and outlet cannot be aligned with the side notch of the protective cover, which will cause the valve inlet and outlet to be skewed, thus affecting the convenience of the operator to connect with the conveying pipeline. For this reason, we propose an acetylene storage cylinder. Content of the Utility Model

[0004] In view of the deficiency that the existing acetylene cylinder is prone to fall over and the valve at its top is easily bent by external force, the utility model provides an acetylene storage cylinder, which has the advantages of being convenient to align the gas cylinder valve with the protective cover and the gas cylinder valve being protected by the protective cover, and solves the problems raised in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0006] Design an acetylene storage cylinder, including a cylinder, a valve seat is installed at the center of the top of the cylinder, a gas cylinder valve is detachably connected in the valve seat, and an annular seat is also provided at the top of the cylinder. The annular seat is coaxial with the cylinder and is located outside the valve seat;

[0007] It also includes a support cylinder, the top of the support cylinder is provided with an annular handle, and the outer side of the bottom of the support cylinder is provided with a fastening ring;

[0008] Two openings are symmetrically opened on the surface of the support cylinder between the fastening ring and the handle, and the upper and lower ends of the openings are respectively located at the fastening ring and the handle;

[0009] Two adjustment openings are symmetrically arranged on the fastening ring, and connecting seats are arranged on both sides of the adjustment openings. The connecting seats are connected by fasteners;

[0010] Among them, the bottom of the support cylinder is sleeved on the annular seat, and then the fasteners are adjusted to drive the fastening ring to tighten and fix on the annular seat by the connecting seats. At this time, the connection port of the gas cylinder valve is placed in the middle of the opening.

[0011] Preferably, two slots are symmetrically arranged at the top of the support cylinder.

[0012] Preferably, the top of the support cylinder is bent outward to form an arc-shaped structure, and the arc-shaped structure forms a handle.

[0013] Preferably, at least one annular groove is arranged on the side surface of the annular seat, and an annular flange corresponding to the annular groove is arranged on the inner surface of the fastening ring, and the annular flange is placed in the annular groove.

[0014] Preferably, an annular base is arranged at the bottom edge of the gas cylinder, and a reinforcing ring is arranged at the bottom of the annular base.

[0015] Preferably, the fastener is a bolt.

[0016] Compared with the prior art, when in use of the present utility model, after the gas cylinder valve is tightened on the top of the gas cylinder, the bottom of the support cylinder is sleeved on the annular seat, and then the fasteners are adjusted for fastening to fix the support cylinder on the top of the gas cylinder;

[0017] The advantage of this is that the installation process of the support cylinder is carried out after the gas cylinder valve is installed, so that the inlet and outlet of the gas cylinder valve are exactly located at the center of the side opening of the support cylinder, which is convenient for the operator to connect the gas cylinder valve with the conduit.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 4 , the present invention provides a technical solution: an acetylene storage cylinder, including a cylinder 1 and a fastener, and the fastener is a bolt.

[0026] As Figure 1 shown, a valve seat 4 is installed at the center of the top of the cylinder 1, a threaded port is provided at the center of the valve seat 4, and a gas cylinder valve 5 is detachably connected inside the valve seat 4, that is, the bottom of the gas cylinder valve 5 is threadedly connected to the threaded port. After the gas cylinder valve 5 is installed on the top of the cylinder, oxygen can be filled into the cylinder for storage. When the gas cylinder valve 5 is opened, oxygen can be released, or external oxygen can be filled into the gas cylinder valve 5.

[0027] In order to protect the gas cylinder valve 5 at the top of the cylinder 1 from being impacted, a detachable protection device is provided at the top of the cylinder 1. That is, the protection device includes a ring seat 2, the ring seat 2 is arranged at the top of the cylinder 1, the ring seat 2 is coaxial with the cylinder 1, and the ring seat 2 is located outside the valve seat 4;

[0028] The protection device also includes a support cylinder 7, a ring-shaped grip 8 is provided at the top of the support cylinder 7, and a fastening ring 6 is provided on the outer side of the bottom of the support cylinder 7;

[0029] Two openings 10 are symmetrically opened on the surface of the support cylinder 7 between the fastening ring 6 and the grip 8. The upper and lower ends of the opening 10 are respectively located at the fastening ring 6 and the grip 8, that is, the opening 10 penetrates the entire side surface of the support cylinder 7;

[0030] Two adjusting openings 12 are symmetrically opened on the fastening ring 6. Connecting seats 13 are provided on both sides of the adjusting opening 12, and the connecting seats 13 are connected by fasteners. As Figure 1 shown, the adjusting opening 12 passes through the diameter of the support cylinder 7, and the adjusting opening 12 is placed in the middle of the opening 10. The set adjusting opening 12 just divides the fastening ring 6 into two halves;

[0031] Specifically, after the gas cylinder valve 5 is tightened on the top of the cylinder 1, the position of the gas cylinder valve 5 is fixed at this time. Then, the bottom of the support cylinder 7 is sleeved on the annular seat 2, and then the fastener (bolt) is adjusted to drive the fastening ring 6 by the connecting seat 13 to tighten and fix on the annular seat 2. Before tightening, the connection port of the gas cylinder valve 5 should be placed in the middle of the opening 10. Because during long-term use, the gas cylinder valve 5 will not be disassembled for no other reason, this can keep the air outlet of the gas cylinder valve 5 always in the middle position of the opening 10, facilitating manual docking and avoiding the air outlet of the gas cylinder valve 5 being placed eccentrically in the opening 10;

[0032] Meanwhile, if the gas cylinder valve 5 is disassembled and reinstalled, only the connecting seat 13 needs to be loosened, and the positions of the opening 10 and the gas cylinder valve 5 can be adjusted again.

[0033] As Figure 3 shown, the connection port can extend from the opening 10 to the outside of the support cylinder 7, but it is still located below the grip 8.

[0034] As Figure 3 shown, the orthographic projection of the edge of the grip 8 is located inside the cylinder 1, as shown by the dotted line in Figure 3 , that is, the length of the edge of the grip 8 extending outwards does not exceed the outside of the side of the cylinder 1. In this way, when the cylinder is tilted, the ground will directly collide with the grip 8 instead of contacting the gas cylinder valve 5, thus protecting the gas cylinder valve 5 from being bent by external force;

[0035] The grip 8 is annular, so the top of the support cylinder 7 is connected to the outside, enabling the top knob of the gas cylinder valve 5 to be placed inside the support cylinder 7, but it can be tightened or opened manually.

[0036] Furthermore, two slots 9 are symmetrically opened at the top of the support cylinder 7. The opened slots 9 facilitate the operator to hold the grip 8 by hand, that is, the palm can pass through the slots 9 and then hold the grip. Here, the grip can be an annular ring, an annular tube or an annular rod, etc. In addition, the top of the support cylinder 7 is bent outwards to form an arc structure, and the arc structure forms the grip 8, so that the grip 8 is directly folded from the top of the support cylinder 7, making the grip 8 and the support cylinder 7 an integral structure, which is more firm as a whole.

[0037] Furthermore, at least one annular groove 3 is opened on the side surface of the annular seat 2, and an annular flange 11 corresponding to the annular groove 3 is provided on the inner surface of the fastening ring 6. After the annular flange 11 is placed in the annular groove 3, the connection between the support cylinder 7 and the annular seat 2 is made closer and will not become loose.

[0038] Furthermore, the acetylene in the cylinder 1 will eventually be used up. Therefore, the empty cylinders need to be replaced at any time, and the empty cylinders can be reused. During these processes, the cylinders need to be carried and then put down, which will accompany the entire life cycle of the cylinders. Therefore, to protect the bottom of the cylinder, a circular base 14 can be provided at the bottom edge of the cylinder 1, and a reinforcing ring 15 is provided at the bottom of the circular base 14. The diameter of the reinforcing ring 15 can be greater than the width of the circular base 14. In this way, when the cylinder is placed on the ground, the reinforcing ring directly contacts the ground surface, avoiding the direct contact between the cylinder and the ground surface.

[0039] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention; the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Moreover, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.
