[0002] A cylinder positioning handwheel is a manual operating component installed on a gas cylinder to control the opening, closing, and adjustment of the cylinder valve. It allows operators to manually apply force to control gas flow and ensures safe gas supply during use in industrial production, laboratories, and other scenarios, preventing potential hazards.

[0003] For example, Chinese Patent Application No. 201720910641.X discloses a steel cylinder, including a cylinder body and a handle fixed to the cylinder body. An exhaust valve is provided on the cylinder body, and an adjustment knob is provided on the exhaust valve. The handle includes two opposing handle units, each with a gripping opening in the middle. A force-bearing portion extends from the upper edge of each handle unit towards the opposing handle unit, and the connection between the force-bearing portion and the upper edge of the handle unit is arc-shaped. The exhaust valve has an external connector for connecting to an external flexible hose. Reinforcing grooves are provided on both sides of the gripping opening on each handle unit along the vertical direction. This utility model has the advantages of wear resistance and convenient handling.

[0004] In practical applications of cylinder positioning handwheels, the handwheel is typically gripped and rotated to control its rotation, thereby operating the connected valve. However, the connection port on the valve surface is usually used to connect to other components and protrudes from the valve surface. During daily use or handling, the connection port and handwheel are prone to collisions, causing them to fail to connect properly or allowing foreign objects to enter.

[0005] Therefore, it is necessary to redesign and modify the cylinder positioning handwheel with protective functions to effectively prevent damage to the handwheel and connection port or the entry of foreign objects. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cylinder positioning handwheel with protective function, which has the advantages of being easy to use and solves the problem that the handwheel and connection port are easily damaged or foreign objects can enter.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel cylinder positioning handwheel with protective function, comprising a steel cylinder, a switch valve mounted on the upper side of the steel cylinder, a protective mechanism provided on the upper side of the steel cylinder, the protective mechanism comprising a fixed cylinder fixedly connected to the upper side of the switch valve, a fixed plate movably connected to the surface of the fixed cylinder via a bearing, an upper protective cylinder fixedly connected to the surface of the fixed plate, a sliding ring fixedly connected to the surface of the upper protective cylinder, and a lower protective cylinder slidably connected to the surface of the sliding ring, the upper and lower protective cylinders being used to protect the switch valve, and a switch mechanism provided on the upper side of the steel cylinder.

[0008] As a preferred embodiment of this utility model, the switching mechanism includes a lifting rod slidably connected to the inner wall of the fixed cylinder, transmission bars are fixedly connected to the left and right sides of the lifting rod, the surface of the transmission bars is slidably connected to the inner wall of the fixed cylinder, and a handwheel is fixedly connected to the upper end of the lifting rod, the handwheel being able to move downward and enter the interior of the upper protective cylinder.

[0009] As a preferred embodiment of this invention, a pull plate is fixedly connected to the upper side of the handwheel, and the pull plate is used to facilitate the gripping and moving of the handwheel by the fingers.

[0010] As a preferred embodiment of this invention, a magnetic ring is fixedly connected to the lower side of the handwheel, and the bottom of the magnetic ring is attracted to the top of the fixed plate.

[0011] As a preferred embodiment of this invention, a toggle ring is fixedly connected to the surface of the lower protective cylinder, and the toggle ring is used to facilitate the upward movement of the lower protective cylinder by the finger.

[0012] In a preferred embodiment of this invention, a support plate is fixedly connected to the surface of the switching valve, and a magnetic ring is fixedly connected to the top of the support plate. The top of the magnetic ring is attracted to the bottom of the lower protective cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

The upper protective cylinder 5 and the lower protective cylinder 7 are used to protect the switch valve 2, and a switch mechanism is provided on the upper side of the cylinder 1.

[0027] refer to Figure 4 The switching mechanism includes a lifting rod 8 that is slidably connected to the inner wall of the fixed cylinder 3. The left and right sides of the lifting rod 8 are fixedly connected to transmission bars 9. The surface of the transmission bars 9 is slidably connected to the inner wall of the fixed cylinder 3. The upper end of the lifting rod 8 is fixedly connected to a handwheel 10. The handwheel 10 can move downward and enter the interior of the upper protective cylinder 5.

[0028] As a technical optimization of this utility model, the switching mechanism is designed with a lifting rod 8 and a transmission bar 9 in conjunction with a handwheel 10. The handwheel 10 can move downwards into the upper protective cylinder 5, which can further reduce the space occupied by the handwheel 10 in the non-operating state, and at the same time avoid the problem of the handwheel 10 protruding and being easily bumped. During operation, the switch valve 2 can be easily controlled by the handwheel 10. The structure is ingenious and practical.

[0029] refer to Figure 3 A pull plate 11 is fixedly connected to the upper side of the handwheel 10. The pull plate 11 is used to facilitate the gripping and moving of the handwheel 10 with fingers.

[0030] As a technical optimization of this utility model, by setting the pull plate 11, a convenient gripping point is provided for the fingers, enabling the operator to move the handwheel 10 more easily and steadily. Especially when it is necessary to overcome the attraction force between the magnetic ring 12 and the fixed plate 4 to lift the handwheel 10, the pull plate 11 can significantly improve the convenience and comfort of operation.

[0031] refer to Figure 4 A magnetic ring 12 is fixedly connected to the lower side of the handwheel 10, and the bottom of the magnetic ring 12 is attracted to the top of the fixed plate 4.

[0032] As a technical optimization of this utility model, by setting a magnetic ring 12, the magnetic ring 12 and the fixed plate 4 are attracted to each other, so that the handwheel 10 can be stably fixed when it is not in operation, preventing the handwheel 10 from shaking or shifting at will, avoiding unnecessary interference or damage to the switch valve 2 caused by the shaking of the handwheel 10, and also reducing noise generation.

[0033] refer to Figure 1A toggle ring 13 is fixedly connected to the surface of the lower protective cylinder 7. The toggle ring 13 is used to facilitate the upward movement of the lower protective cylinder 7 by the finger.

[0034] As a technical optimization of this utility model, by setting a toggle ring 13, it is convenient for the operator to move the lower protective cylinder 7 upward with their fingers, making the operation more labor-saving and quick. Especially when the switch valve 2 needs to be operated frequently, the toggle ring 13 can greatly improve work efficiency and reduce the difficulty of operation.

[0035] refer to Figure 2 A support plate 14 is fixedly connected to the surface of the switch valve 2, and a magnetic ring 15 is fixedly connected to the top of the support plate 14. The top of the magnetic ring 15 is attracted to the bottom of the lower protective cylinder 7.

[0036] As a technical optimization of this utility model, by setting a support plate 14 and a magnetic ring 15, the magnetic ring 15 can be attracted to the bottom of the lower protective cylinder 7, which can firmly fix the lower protective cylinder 7 when it slides back to its original position, ensuring that the protective mechanism is always in a stable state when not in operation, effectively protecting the switch valve 2 and preventing the lower protective cylinder 7 from accidentally sliding down or loosening.

[0037] The working principle and usage process of this utility model are as follows: In the initial state, the upper protective cylinder 5 and the lower protective cylinder 7 remain relatively stable due to the attraction between the magnetic ring 15 and the bottom of the lower protective cylinder 7, and between the magnetic ring 12 and the top of the fixed plate 4, thus protecting the switch valve 2 and the handwheel 10. When it is necessary to operate the switch valve 2, the handwheel 10 is lifted upward by the pull plate 11, causing the magnetic ring 12 to separate from the fixed plate 4. At the same time, the handwheel 10 drives the lifting rod 8 and the transmission bar 9 to move upward inside the fixed cylinder 3. At this time, the handwheel 10 is disengaged from the interior of the upper protective cylinder 5, and the opening and closing of the switch valve 2 can be controlled by the handwheel 10. By flicking the actuating ring 13 with your finger, the attraction between the magnetic ring 15 and the lower protective cylinder 7 is overcome, causing the lower protective cylinder 7 to slide upwards along the sliding ring 6, exposing the connection port of the switch valve 2. Normal connection can then be made. After operation, slide the lower protective cylinder 7 back to its original position, allowing its bottom to engage with the magnetic ring 15. Then, press down the handwheel 10 to engage the magnetic ring 12 with the fixed plate 4, restoring the protection of the switch valve 2. This design prevents foreign objects from easily entering the handwheel 10 of the gas cylinder 1 and the connection port of the switch valve 2, thus providing ease of use.

[0038] In summary, when this utility model is in use, the protective mechanism and the switching mechanism can shield and protect the handwheel 10 and the switching valve 2, preventing foreign objects from easily entering the connection port of the handwheel 10 of the gas cylinder 1 and the switching valve 2 and preventing collision damage, thus giving it the advantage of being easy to use.
