Description

Technical Field

[0001] The utility model relates to the technical field of steel cylinder detection, in particular to a fixing device for liquefied gas steel cylinder weight detection equipment. Background Art

[0002] A gas cylinder is a type of movable pressure vessel with a bottle-shaped main structure, generally filled with gas, which can be compressed gas, liquefied gas, dissolved adsorbed gas, etc., and requires weight inspection before leaving the factory.

[0003] A Chinese patent discloses a fixing device for gas cylinder detection, with the publication number CN213647454U, comprising a fixing frame, a gas cylinder body is placed inside the fixing frame, first springs are fixedly installed on both sides of the inner cavity of the fixing frame, a first clamping plate is fixedly installed on one end of the first spring, one side of the first clamping plate is clamped on the surface of the gas cylinder body, a frame is provided on the top of the fixing frame, and adjusting screws are provided through both sides of the top of the frame, and the lower end of the adjusting screw is rotatably installed with the top of the fixing frame. The utility model supports the first clamping plate and the second clamping plate by two springs, so that the positions of the two clamping plates can be adjusted conveniently, and the upper and lower ends of the gas cylinder body can be clamped and fixed respectively, thereby ensuring the firmness after clamping. At the same time, the frame is fixed to the top of the fixing frame by the adjusting screw, and the frame can be adjusted according to the height of the gas cylinder, thereby adjusting the position of the second clamping plate inside.

[0004] However, it still has the following disadvantages: the device uses the elastic force of the first spring to position the bottom of the gas cylinder with the first clamping plate, and uses the elastic force of the second spring to position the top of the gas cylinder with the second clamping plate. However, when installing the gas cylinder, the gas cylinder needs to be lifted up to a level higher than the top surface of the frame before it can be removed, which is quite troublesome. Therefore, we propose a fixing device for the liquefied gas cylinder weight detection equipment to solve this problem. Utility Model Content
