Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas transportation technology, specifically to a gas cylinder with a valve protection structure. Background Technology
[0002] Gas cylinders are bottle-shaped and are generally filled with compressed gases, liquefied gases, dissolved gases, etc. They are a type of portable pressure vessel with a wide range of applications, almost indispensable in both production and daily life. As a pressure-bearing device, the medium it carries is generally flammable, explosive, toxic, or highly corrosive. The operating environment is more complex and harsher than other pressure vessels due to its mobility, repeated filling, non-fixed personnel, and changing conditions. Therefore, meticulous protection is required during transportation. An explosion or leak in a gas cylinder often leads to fires, poisoning, or even catastrophic accidents, causing severe property damage, casualties, and environmental pollution. Currently, gas cylinder transportation typically involves densely arranging cylinders in flatbed trucks, using compression to keep them upright, or further restraining them with straps. However, the smooth surface of the cylinders results in uneven stress, making them difficult to grip and prone to tipping over during transport. Furthermore, the valves on existing gas cylinders are generally unprotected, posing a significant safety hazard. Utility Model Content
[0003] The technical problem to be solved by this utility model is that existing gas cylinders generally do not have complete protective measures during transportation, which makes the gas cylinder valves prone to collision when tilted, posing a great safety hazard. At the same time, existing gas cylinders have few gripping points during handling, which also poses certain safety hazards.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a gas cylinder with a valve protection structure, comprising a gas cylinder body and a valve protection device.

Detailed Implementation
[0016] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0017] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to facilitate the description of the embodiments and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0018] Please see Figure 1 This embodiment discloses a gas cylinder with a valve protection structure, including a gas cylinder body 1 and a valve protection device 2, which will be described in detail below with reference to the accompanying drawings.
[0019] Please see Figures 1 to 3In this embodiment, the neck of the gas cylinder body 1 is provided with an assembly part for connecting to the valve protection device 2. The valve protection device 2 includes a protective frame 21, a quick-release locking mechanism 22, and a valve protection mechanism 23. The quick-release locking mechanism 22 includes a quick-release connecting part 221, a quick-release buckle part 222, and a quick-release locking part 223. The quick-release buckle part 222 is installed at one end of the quick-release connecting part 221, and the quick-release locking part 223 is installed at the other end of the quick-release connecting part 221. The quick-release connecting part 221 is detachably wrapped around the neck of the gas cylinder body 1. The inner side of the quick-release connecting part 221 is provided with a connecting part for connecting to the assembly part. After the quick-release buckle part 222 and the quick-release locking part 223 are locked together, the connecting part is connected to the assembly part. The protective frame 21 is connected to the outer surface of the quick-release connecting part 221. The valve protection mechanism 23 is arranged inside the protective frame 21 and wraps around the corresponding valve on the gas cylinder body 1.
[0020] In this embodiment, the quick-release locking mechanism 22 enables the detachable installation of the protective frame 21, which is convenient and quick to operate. The protective frame 21 can greatly reduce the probability of the valve of the gas cylinder body 1 being hit by a collision and can provide sufficient gripping position for the handling personnel. Furthermore, the valve protection mechanism 23 completely encloses the valve of the gas cylinder body 1, achieving comprehensive protection for the valve of the gas cylinder body 1.
[0021] As a further improvement of this embodiment, the neck of the gas cylinder body 1 is provided with an assembly groove 11 for connecting with the valve protection device 2. In actual operation, the assembly groove 11 is the groove of the neck of the existing standard gas cylinder body 1. Therefore, this embodiment can be applied to various existing gas cylinder bodies 1 with grooves without special production, which greatly improves the application range of this embodiment and facilitates promotion. The assembly groove 11 is arranged around the circumference of the gas cylinder body 1. The cross-sectional shape of the quick-release connection part 221 is set as a notched annular shape. A connecting protrusion 2211 matching the assembly groove 11 is provided at the middle position of the inner side of the quick-release connection part 221. The connecting protrusion 2211 is inserted into the assembly groove 11 when the quick-release locking mechanism 22 is locked.
[0022] During operation, simply release the quick-release locking mechanism 22, making the inner end dimension of the connecting protrusion 2211 larger than the diameter of the top of the assembly groove 11. Then, place the valve protection device 2 around the neck of the gas cylinder body 1. Next, through the cooperation of the quick-release locking part 223 and the quick-release buckle part 222, drive the quick-release connecting part 221 to close. At this time, the connecting protrusion 2211 is inserted into the assembly groove 11, realizing the connection between the valve protection device 2 and the gas cylinder body 1. Preferably, the bottom shape of the quick-release connecting part 221 is set to a flared shape that matches the neck shape of the gas cylinder body 1. When the quick-release locking mechanism 222 is locked, the bottom of the inner side of the quick-release connecting part 221 is flush with the outer surface of the gas cylinder body 1. The close contact, through friction, makes the valve protection device 2 less likely to be rotated during use, improving the gripping experience and ensuring the handling efficiency of the gas cylinder body 1. During operation, the quick-release connection part 221 can be made of metal material, which can improve the connection strength and service life of the quick-release locking mechanism 22. As a further improvement of this embodiment, the bottom of the inner side of the quick-release connection part 221 is provided with an elastic layer. When the quick-release locking mechanism 222 is locked, the bottom of the inner side of the quick-release connection part 221 is press-fitted with the outer surface of the gas cylinder body 1, which can avoid excessive wear on the gas cylinder body 1 caused by the metal quick-release connection part 221 during use, thus ensuring the service life of the gas cylinder body 1.
[0023] Preferably, at least two sets of cooperating quick-release buckle parts 222 and quick-release locking parts 223 can be provided. The two sets of quick-release buckle parts 222 and quick-release locking parts 223 are arranged sequentially along the axial direction of the gas cylinder body 1. The quick-release locking part 223 includes a rotating base 2231, a locking handle 2232, a connecting shaft 2233, a U-shaped connecting hook 2234, and an adjusting nut 2235. One end of the locking handle 2232 is rotatably mounted on the rotating base 2231, and the connecting shaft 2233 is rotatably arranged in the middle position of the locking handle 2232. The axial direction of the connecting shaft 2233 is parallel to the rotation direction of the locking handle 2232. The two ends of the connecting shaft 2233 extend outward from both sides of the locking handle 2232 and are respectively provided with openings for the two ends of the U-shaped connecting hook 2234 to pass through. Both ends of the U-shaped connecting hook 2234 are provided with threads for threaded connection with the adjusting nut 2235. The length of the U-shaped connecting hook 2234 is set to be adjustable when the adjusting nut 2235 rotates. The locking force can be adjusted as needed during adjustment, which is convenient to be applied to gas cylinder bodies 1 of different sizes, has a certain degree of versatility, and saves mold costs.
[0024] In specific implementation, the protective frame 21 includes a ring-shaped handle portion 211 and several support portions 212. The several support portions 212 are arranged around the handle portion 211 in the axial direction. The top of the several support portions 212 is connected to the bottom of the handle portion 211, and the bottom of the several support portions 212 is connected to the outer surface of the quick-release connecting portion 221. During operation, in order to reduce the driving force of the quick-release locking mechanism 22 when locking, the support portions 212 near the quick-release buckle portion 222 and the quick-release locking portion 223 can be installed by a movable connection, so that the corresponding adjacent support portions 212 are kept at a distance to leave an operating window for the operator to lock or release the quick-release locking mechanism 22.
[0025] Preferably, the valve protection mechanism 23 includes a valve protection cover 231 and a leakage detection device. The valve protection cover 231 is arranged inside the protection frame 21 and covers the corresponding valve periphery on the gas cylinder body 1. The leakage detection device is arranged inside the valve protection cover 231 and outputs an alarm signal when a leak occurs in the valve of the gas cylinder body 1. In specific implementation, the outer surface of the valve protection cover 231 is detachably connected to the protection frame 21 through corresponding connecting components. For example, the valve protection cover 231 can be fixed to the protection frame 21 by bolt connection. A connecting frame can be set at the top middle position of the protection frame 21. The middle of the connecting frame has an opening for the valve protection cover 231 to cover the periphery of the valve of the gas cylinder body 1, and a through hole for threaded connection with the valve protection cover 231. When full protection of the valve of the gas cylinder body 1 is required, the valve protection cover 231 is installed in place. In daily use, the valve protection cover 231 can be removed to facilitate the installation of corresponding pipelines by operators.
[0026] The beneficial technical effects of this embodiment include: the present invention achieves detachable installation of the protective frame through a quick-release locking mechanism, which is convenient and quick to operate. The protective frame wrapped around the gas cylinder valve can greatly reduce the probability of it being hit by a collision and provide sufficient gripping position for handling personnel. Furthermore, the valve protection mechanism completely wraps around the gas cylinder valve, achieving comprehensive protection of the gas cylinder valve.
