Description

Technical Field

[0001] This utility model relates to the field of special gas supply cabinet technology, specifically to a gas cylinder limiting structure for a gas supply cabinet. Background Technology

[0002] Special gas supply cabinets are mainly used to supply special gases, such as flammable, explosive, and highly toxic gases. They are primarily used in emerging industries such as semiconductors and LEDs. Based on their functional design, they can be divided into single-cylinder, double-cylinder, and triple-cylinder designs. Single-cylinder designs are typically used in research institutions or laboratories, while double-cylinder and triple-cylinder designs are commonly used in mass production plants where process downtime is not permitted. When one cylinder is used up, the other spare cylinder will automatically switch to supply gas. To improve the stability of the gas cylinder during use, a cylinder limiting structure is used to fix it in place.

[0003] Currently, the following problems still exist in the use of special gas cabinets: the gas cylinder limiting structure is generally fixed by using iron chains to prevent the gas cylinder from tipping over. However, the iron chain is of fixed length and it is difficult to achieve a good fixing effect on gas cylinders of different diameters. In addition, after the special gas supply is used up, the existing gas cylinders need to be removed from the special gas cabinet and transferred to the filling point for refilling, which is inconvenient.

[0004] In summary, a gas cylinder limiting structure for gas supply cabinets is currently needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a gas cylinder limiting structure for a gas supply cabinet, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gas cylinder limiting structure for a gas supply cabinet includes a limiting bracket. A support plate is fixedly installed on the front side of the limiting bracket. A first through hole is opened on the support plate. A first screw is inserted through the first through hole. The inner end of the first screw is threaded through a second through hole and a fixing hole. The second through hole is opened on the fixing bracket. The fixing hole is opened on the side of the support plate.

[0008] Furthermore, the baffle is located on the upper end of the support frame, and a movable wheel is provided below the support frame. An opening slot is provided on the rear side of the baffle.

[0009] Furthermore, the upper end of the support frame is provided with a placement groove, which is located on the front side of the baffle, and a fixing plate is fixedly installed on the upper end of the support frame near the rear side.

[0010] Furthermore, a second screw is threaded through both the fixed plate frame and the fixed frame, and the inner end of the second screw is rotatably connected to the limiting stop.

[0011] Furthermore, a guide rod is fixedly installed on the outer side of the limiting bracket. The guide rod is located below the second screw, and the outer end of the guide rod passes through the fixing plate and the fixing frame respectively.

[0012] Furthermore, the support frame is provided with three, with the first through holes on the left and right support frames corresponding to the first through holes on the middle support frame.
