Description

Technical Field

[0001] This utility model belongs to the field of liquefied gas cylinder opening and closing technology, specifically an indoor safety opening and closing device for outdoor liquefied gas cylinders. Background Technology

[0002] In modern daily life and industrial production, liquefied petroleum gas (LPG) cylinders have become an indispensable energy supply medium due to their portability and high energy efficiency. Whether for daily cooking in households or providing power for certain industrial processes, LPG cylinders play a vital role. However, it is crucial to recognize that the flammable and explosive gases stored in LPG cylinders can potentially lead to serious safety accidents if mishandled during use, posing a significant threat to life and property.

[0003] According to relevant safety standards and regulations, effectively isolating the operating room from the gas cylinders and ensuring they are kept away from heat and ignition sources is a crucial measure to reduce the risks associated with using liquefied petroleum gas (LPG) cylinders. The proximity of LPG cylinders to heat and ignition sources places them in a high-risk environment. In the event of a gas leak, under high temperatures or open flames, it can easily trigger explosions, fires, and other serious accidents with unimaginable consequences. Therefore, separating the operating room from the gas cylinders and keeping them away from heat and ignition sources will significantly reduce the hazards associated with using LPG cylinders.

[0004] Due to the physical barriers between indoor and outdoor spaces, operators cannot directly open or close liquefied gas cylinders indoors. They must go outside to manually open or close the cylinders, which is inconvenient for users. Each time the cylinder is used or closed, additional operations and time are required, which is time-consuming and laborious. In addition, if the operation is improper, negligent, or in case of an emergency (such as a gas leak), the cylinder may not be able to be closed in time, which may lead to dangers such as fire or explosion. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies, such as the time-consuming and laborious process of opening and closing liquefied gas cylinders and the safety risks caused by untimely opening and closing of liquefied gas cylinders, this utility model provides an indoor safety device for opening and closing outdoor liquefied gas cylinders.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an indoor safety opening and closing device for outdoor liquefied gas cylinders, including a horizontal steel pipe and a vertical steel pipe, the horizontal steel pipe and the vertical steel pipe are connected and fixed by stiffening plates, a horizontal rotating shaft is sleeved inside the horizontal steel pipe, a vertical rotating shaft is sleeved inside the vertical steel pipe, a first bevel gear is installed at the left end of the horizontal rotating shaft, a handle is provided at the right end of the horizontal rotating shaft, a second bevel gear is provided at the upper end of the vertical rotating shaft, and a claw is installed at the lower end of the vertical rotating shaft.

[0007] As a further improvement of this utility model, the stiffening plate is fixedly connected to both the horizontal and vertical steel pipes by welding.

[0008] As a further improvement of this utility model, a first bearing is provided between the first bevel gear and the horizontal steel pipe, and a second bearing is provided between the second bevel gear and the vertical steel pipe.

[0009] As a further improvement of this utility model, the claw has a C-shaped structure, and the inner sides of the two branches at the open end are provided with inwardly inclined locking teeth, which facilitates the secure locking of the liquefied gas cylinder valve.

[0010] As a further improvement of this utility model, the first bevel gear and the second bevel gear mesh with each other, and their modules and pressure angles are equal.

[0011] As a further improvement of this utility model, the surface of the handle is provided with anti-slip texture.

[0012] As a further improvement of this utility model, the horizontal and vertical steel pipes are made of stainless steel, which has good corrosion resistance and extends the service life of the device.

[0013] As a further improvement of this utility model, a torque limiter is provided at the connection between the horizontal rotating shaft and the handle. When the torque applied to the handle exceeds the preset value, the torque limiter is activated to prevent damage to the liquefied gas cylinder valve due to excessive force.

[0014] As can be seen from the above technical solution, the beneficial effects of this utility model are: the device controls the valve of the outdoor liquefied gas cylinder by operating it indoors, avoiding direct contact between the operator and the liquefied gas cylinder outdoors, reducing potential safety risks. The operator can control the claw to operate the valve of the liquefied gas cylinder by turning the handle indoors, without the need for complicated manual operation outdoors. Especially for some liquefied gas cylinders with inconvenient installation locations, the operation is more convenient, improving operating efficiency, saving time and effort, and in case of emergencies, it can shut off the liquefied gas cylinder in time, improving safety.

[0018] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0019] like Figure 1 As shown, this utility model discloses an indoor safety device for opening and closing outdoor liquefied gas cylinders, including a horizontal steel pipe 1 and a vertical steel pipe 2. The horizontal steel pipe 1 and the vertical steel pipe 2 are connected and fixed by a stiffening plate 3. A horizontal rotating shaft 4 is sleeved inside the horizontal steel pipe 1, and a vertical rotating shaft 5 is sleeved inside the vertical steel pipe 2. A first bevel gear 6 is installed at the left end of the horizontal rotating shaft 4, a handle 7 is provided at the right end of the horizontal rotating shaft 4, a second bevel gear 8 is provided at the upper end of the vertical rotating shaft 5, and a claw 9 is installed at the lower end of the vertical rotating shaft 5.

[0020] A first bearing 10 is provided between the first bevel gear 6 and the horizontal steel pipe 1, and a second bearing 11 is provided between the second bevel gear 8 and the vertical steel pipe 2. The first bevel gear 6 and the second bevel gear 8 mesh with each other, and their modules and pressure angles are equal.

[0021] When the operator turns handle 7, the handle drives the horizontal shaft 4 to rotate within the horizontal steel pipe 1. The horizontal shaft 4 is rotatable within the horizontal steel pipe 1, and the first bevel gear 6 mounted on its left end rotates synchronously with the horizontal shaft 4. The first bevel gear 6 is connected to the horizontal steel pipe 1 via a first bearing 10, which reduces frictional resistance during rotation, allowing the first bevel gear 6 to rotate more smoothly. Similarly, the vertical shaft 5 is rotatable within the vertical steel pipe 2, and the second bevel gear 8 rotates synchronously with the vertical shaft 5. The second bevel gear 8 is connected to the vertical steel pipe 2 via a second bearing 11, which reduces friction. The first bevel gear 6 and the second bevel gear 8 mesh with each other. According to the gear transmission principle, when two meshing bevel gears have equal modules and pressure angles, stable and efficient power transmission can be achieved. When the handle 7 at the right end of the horizontal shaft 4 is rotated, the horizontal shaft 4 drives the first bevel gear 6 to rotate. Due to the meshing relationship of the two bevel gears, the rotation of the first bevel gear 6 drives the second bevel gear 8, which meshes with it, to rotate through the interaction of the tooth surfaces. Since the second bevel gear 8 is fixedly connected to the vertical shaft 5, the vertical shaft 5 will also rotate along with the second bevel gear 8, thereby causing the vertical shaft 5 to rotate.

[0022] The use of the first bearing 10 and the second bearing 11 not only reduces the frictional resistance between transmission components but also reduces the wear of the components, thereby extending the service life of the entire device. The improved stability of the transmission system reduces the number of equipment repairs and maintenance costs caused by transmission failures. At the same time, the device has a simple structure and clearly defined connections between components, facilitating disassembly and installation. When maintenance or component replacement is required, operators can quickly complete the relevant work, reducing maintenance difficulty and time costs.

[0023] The first bearing 10 and the second bearing 11 not only reduce frictional resistance but also provide support and positioning for the rotating shaft. Taking the first bearing 10 as an example, it is installed between the first bevel gear 6 and the horizontal steel pipe 1. On the one hand, the balls or rollers inside it convert sliding friction into rolling friction when rotating, greatly reducing friction and making the first bevel gear 6 rotate more easily. On the other hand, the bearing can limit the radial and axial displacement of the horizontal rotating shaft 4, ensuring that the horizontal rotating shaft 4 always remains in the correct position during rotation, guaranteeing the meshing accuracy between the first bevel gear 6 and the second bevel gear 8, and avoiding problems such as transmission instability or accelerated gear wear caused by shaft displacement. The second bearing 11 also provides the same support and positioning for the vertical rotating shaft 5, ensuring the stability and reliability of the entire transmission system.

[0024] A C-shaped gripper 9 is installed at the lower end of the vertical rotating shaft 5. The two branches at the open end of the gripper 9 have inwardly inclined locking teeth to securely hold the liquefied gas cylinder valve. When the vertical rotating shaft 5 rotates, the gripper 9 rotates accordingly. By rotating the handle 7, the position of the gripper 9 can be controlled, enabling the opening and closing of the liquefied gas cylinder valve. When the vertical rotating shaft 5 rotates, the rotation trajectory of the gripper 9 is a circular motion centered on the axis of the vertical rotating shaft 5. By precisely controlling the rotation angle of the handle 7, the rotation angle and position of the gripper 9 can be precisely controlled, thereby achieving precise opening and closing of the liquefied gas cylinder valve.

[0025] The anti-slip texture on the handle 7 surface increases the friction between the hand and the handle, making the operator more stable and less prone to slipping when turning the handle. From a microscopic perspective, this increased friction is achieved by increasing the roughness of the contact surface. These textures may take various forms, such as horizontal lines, vertical lines, diamond patterns, or granular raised areas, with the aim of disrupting the smooth contact that might otherwise exist between the hand and the handle, increasing the coefficient of kinetic friction μ. When the operator grips the handle and applies a turning force, these textures effectively embed into the texture of the hand's skin, creating a mechanical interlocking effect that further enhances friction. In practical operating scenarios, whether in a humid kitchen environment or when the operator's hands are sweaty or oily from prolonged work, the anti-slip texture plays a crucial role in ensuring a stable grip on the handle, effectively preventing loss of control due to hand slippage, and making the turning of the handle more precise and smooth, thus providing a strong guarantee for the stable operation of the entire device.

[0026] The horizontal steel pipe 1 and the vertical steel pipe 2 are made of stainless steel, which has good corrosion resistance to extend the service life of the equipment.

[0027] The stiffening plate 3 is fixedly connected to both the horizontal steel pipe 1 and the vertical steel pipe 2 by welding, ensuring the stability of the device structure. Welding is a process that fuses metal components at high temperatures, resulting in welds with high strength and tight bonding. This connection method effectively prevents relative displacement or angular changes between the horizontal steel pipe 1 and the vertical steel pipe 2, providing a solid foundation for the entire transmission system. During device operation, even under significant external forces or vibrations from frequent operation, the stability of the welding ensures that all components work together effectively, and transmission efficiency and operational accuracy are not affected by structural loosening.

[0028] This device allows for indoor operation to control the valve of an outdoor liquefied petroleum gas (LPG) cylinder, avoiding direct contact between operators and the cylinder, thus reducing potential safety risks. Operators can control the gripper 9 to operate the cylinder valve by turning handle 7 indoors, eliminating the need for complex manual operations outdoors. This is especially convenient for LPG cylinders in inconvenient installation locations, improving operational efficiency, saving time and effort, and enabling timely shutdown of the cylinder in case of emergencies, thus enhancing safety.

[0029] Meshing bevel gears with equal module and pressure angle enable precise power transmission, allowing for more accurate control of the rotation angle and position of the gripper 9. This facilitates precise locking and operation of the LPG cylinder valve, preventing incomplete valve opening or closing due to operational errors. The C-shaped structure of the gripper 9, with its inwardly inclined locking teeth, better conforms to the LPG cylinder valve, firmly locking it and preventing slippage between the gripper and the valve during operation, thus ensuring operational reliability.

[0030] A torque limiter is provided at the connection between the horizontal rotating shaft 4 and the handle 7. When the torque applied to the handle exceeds the preset value, the torque limiter is activated to prevent damage to the liquefied gas cylinder valve due to excessive force.

[0031] This device moves the operation of liquefied petroleum gas (LPG) cylinder valves from outdoors to indoors, significantly reducing the various safety hazards that operators might face when handling LPG cylinders outdoors. For example, in severe weather conditions such as heavy rain and strong winds, outdoor operation of LPG cylinders may lead to operational errors due to environmental factors, resulting in dangerous situations such as gas leaks. Using this device can avoid these risks. Furthermore, some older LPG cylinders may have potential safety issues such as leaky valve seals or cylinder corrosion. Operating indoors reduces the chance of direct contact with these hazardous parts, improving operational safety. In emergencies such as sudden fires, operators can quickly close the LPG cylinder valves indoors, cutting off the gas supply and effectively preventing the spread of fire, buying valuable time for evacuation and firefighting rescue efforts.
