Description

Technical Field

[0001] The utility model relates to the technical field of gas protection devices, in particular to a protection device for standard gas. Background Art

[0002] Gas protection devices are a set of systems and equipment specially designed to ensure the high quality and safe transmission of gases. In the industrial field, these devices play a vital role. They cover the entire process from gas generation, purification, transportation to final use, ensuring that industrial gases can effectively play their core functions in various production and scientific research activities. For example, acetylene, hydrogen and other flammable and explosive gases that are indispensable for industrial production are safely stored in cylinders before use. During the transportation and use of cylinders, protection devices are particularly important. They fix the cylinders to ensure their stability during movement or operation and prevent any possible tipping or vibration, thereby maintaining the safety of the gas and the integrity of the cylinders.

[0003] After searching, a welding gas protection device disclosed in the utility model patent with Chinese patent publication number CN214134571U includes a first plate body, a shell is welded on the upper surface of the first plate body, a slide groove is opened at the center of the inner bottom wall of the shell, the inner wall of the slide groove is symmetrically slidably connected with two second plate bodies, two pull rings are symmetrically welded on the adjacent sides of the two second plate bodies, the inner wall of the slide groove is provided with a tension spring, the two ends of the tension spring are fixedly connected to the inside of the two pull rings, and the top of the second plate body is fixedly connected with a first clamping plate; when using the device, the second plate body is pulled by the tension spring at the bottom of the shell to fix the tank body entering the shell to prevent the tank body from tipping over, causing damage to the tank body and failing to work, the sponge plate and the second spring inside the shell cooperate to further improve the stability of the tank body, and universal wheels and handles are arranged on the outside of the shell. When welding, a single person can complete the welding task without the need for multiple people.

[0004] Although the above utility model patent realizes the protection of tanks of different specifications, there is still room for improvement. The tank for storing gas needs to be inserted into the shell from the top, which means that when fixing the tank, the staff needs to lift it significantly. In view of the considerable weight of the tank after filling with gas, this undoubtedly increases the workload of the operator. In addition, the universal wheel, as the core component of the mobile device, although it provides flexibility, is not designed with a corresponding limiting structure, which leads to insufficient stability during movement and poses a safety hazard. Therefore, a protection device for standard gas is proposed to solve the above problems. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] 1. The protection device for standard gas realizes convenient transportation and firm fixation of the gas storage cylinder by means of the provided protection structure. Specifically, the operator first moves the gas storage cylinder from the left side of the stable base to the top of the stable base, and ensures that the bottom of the gas storage cylinder is smoothly docked with the limiting base.

Specifically, by threading the fixed threaded rod inside the limit plate with the threaded sleeve on the side of the connecting plate close to the supporting base plate, the universal wheel can be effectively limited and fixed, so that the operator can easily push the entire protective device to move in the workplace, thereby improving the flexibility of the device; when it is necessary to improve the stability of the protective device, it is only necessary to remove the fixed threaded rod to disconnect it from the threaded sleeve. At this time, the universal wheel loses its restriction and can be lifted up and off the ground, while making the supporting base plate contact with the ground, thereby increasing the friction between the entire protective device and the ground, thereby significantly improving the stability of the gas protective device during use, and can provide sufficient stability without hindering the flexibility of movement, so that the staff can complete the work more safely and effectively during welding or mobile operations, thereby improving work efficiency and safety.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 In this embodiment, a protection device for standard gas includes a stable base 1, a supporting base plate 2 is fixedly installed at the bottom of the stable base 1, a moving structure 3 is arranged on the top of the stable base 1, a protection structure 4 is arranged on the top of the stable base 1, and a gas storage cylinder 5 is arranged inside the protection structure 4;

[0027] The mobile structure 3 includes a connecting rod 301, a rotating rod 302, a sleeve rod 303, a connecting plate 304, a universal wheel 305, a threaded sleeve 306, a limit plate 307 and a fixed threaded rod 308. Two connecting rods 301 are fixedly installed on the left and right sides of the stable base 1, a rotating rod 302 is fixedly installed between every two connecting rods 301, the outer parts of the two rotating rods 302 are sleeved with sleeve rods 303, two connecting plates 304 are fixedly installed on the bottoms of the two sleeve rods 303, universal wheels 305 are movably installed on the bottoms of the four connecting plates 304, threaded sleeves 306 are fixedly installed on one side of the four connecting plates 304 close to the supporting base plate 2, two limit plates 307 are fixedly installed on the bottom of the stable base 1, and two fixed threaded rods 308 are threadedly connected to the insides of the two limit plates 307;

[0028] The protective structure 4 includes a limiting base 401, a first fixed column 402, a second fixed column 403, a first arc-shaped clamping plate 404, a second arc-shaped clamping plate 405, a slider 406, a limiting top plate 407, a fixing seat 408 and a fixing screw 409. The limiting base 401 is fixedly installed on the top of the stable base 1, the first fixed column 402 is fixedly installed on the top of the stable base 1, the second fixed column 403 is hinged on the top of the stable base 1, two first arc-shaped clamping plates 404 are fixedly installed on the outside of the second fixed column 403, two second arc-shaped clamping plates 405 are fixedly installed on the outside of the first fixed column 402, the slider 406 is slidably connected to the outside of the first fixed column 402, the limiting top plate 407 is fixedly installed on the outside of the slider 406, the limiting top plate 407 is fixedly installed on the outside of the limiting top plate 407, the fixing seat 408 is fixedly installed on the outside of the second fixed column 403, and the fixing screw 409 is threadedly connected to the inside of the second fixed column 403.

[0029] Specifically, the inner walls of the limiting base 401, the first arc-shaped clamping plate 404, the second arc-shaped clamping plate 405 and the limiting top plate 407 are all fixedly installed with rubber buffer pads to provide additional buffering and protection to reduce the impact and vibration caused to the gas storage cylinder 5 during transportation or use. This can prevent the cylinder from being damaged due to collision or friction, ensuring the safe storage and transportation of standard gas. The rubber buffer pad has anti-slip and shock-absorbing properties, and can effectively absorb and disperse external forces, thereby reducing the potential risk of damage to the cylinder.

[0030] Specifically, the bottom of the gas storage cylinder 5 is smoothly docked with the limiting base 401, which is for preliminary fixation of the bottom of the gas storage cylinder 5; the first arc-shaped clamping plate 404 is tightly fitted with the second arc-shaped clamping plate 405, and is firmly fixed by the cooperation of the connecting screw and the connecting piece, which is for further fixation in the horizontal direction of the gas storage cylinder 5; and the lower sliding slider 406 allows the top of the gas storage cylinder 5 to pass through the hole inside the limiting top plate 407 and extend out, and the threaded connection of the fixing screw 409 of the limiting top plate 407 and the fixing seat 408 is completed by fixing, which is for further fixation in the vertical direction of the gas storage cylinder 5. Under the triple limiting fixation, the stability of the gas storage cylinder 5 is greatly improved, and the entire protective device has a better protection effect on the gas storage cylinder 5.

[0031] To sum up, the protection device for standard gas realizes convenient transportation and firm fixation of the gas storage cylinder 5 through the set protection structure 4. Specifically, the operator first moves the gas storage cylinder 5 from the left side of the stable base 1 to the top of the stable base 1, and ensures that the bottom of the gas storage cylinder 5 is smoothly docked with the limiting base 401. Then, the operator lifts the first fixing column 402, so that the first arc-shaped clamping plate 404 and the second arc-shaped clamping plate 405 fit tightly, and are firmly fixed by the cooperation of the connecting screw and the connecting piece. Finally, the operator slides the slider 406 downward to make the top of the gas storage cylinder 5 pass through the hole inside the limiting top plate 407 and extend out, and uses the threaded connection between the fixing screw 409 and the fixing seat 408 to complete the fixation of the limiting top plate 407, thereby reliably fixing the gas storage cylinder 5. This process significantly reduces the height that the operator needs to lift when installing a heavy tank filled with gas, effectively reducing his workload.

[0032] In addition, the protective device for standard gas achieves the dual functions of easy movement and stable fixation through the provision of a movable structure 3. Specifically, by threading the fixed threaded rod 308 inside the limiting plate 307 with the threaded sleeve 306 on the side of the connecting plate 304 close to the supporting base plate 2, the universal wheel 305 can be effectively limited and fixed, so that the operator can easily push the entire protective device to move in the workplace, thereby improving the flexibility of the device; when it is necessary to improve the stability of the protective device, it is only necessary to remove the fixed threaded rod 308 to disconnect it from the threaded sleeve 306. At this time, the universal wheel 305 loses its restriction and can be lifted up and off the ground, while making the supporting base plate 2 contact with the ground, thereby increasing The friction between the entire protective device and the ground significantly improves the stability of the gas protective device during use, and can provide sufficient stability without hindering the flexibility of movement, so that workers can complete their work more safely and effectively during welding or mobile operations, improving work efficiency and safety, and solving the problem that the gas storage tank needs to be inserted into the shell from the top, which means that when fixing the tank, the staff needs to lift it significantly. In view of the considerable weight of the tank after filling with gas, this undoubtedly increases the workload of the operator. In addition, the universal wheel, as the core mobile component, although it provides flexibility, is not designed with a corresponding limiting structure, which leads to insufficient stability during movement and the existence of safety hazards.
