Gas storing tank flow adjusting structure used for slowly descending air cylinder

Abstract

The invention discloses a gas storing tank flow adjusting structure used for slowly descending an air cylinder. The structure comprises a base, and a tank body connected with the base. The interior ofthe tank body is hollow, and the bottom of the tank body is opened. A skirt portion is formed on the upper surface of the base. The skirt portion is integrally combined with the base at the peripheryof the base, and vertically extends upwards from the periphery of the base to form an upper opening. A lower opening is formed in the lower surface of the base. An adjusting channel vertically penetrating through the base is arranged in the lower opening in a communicating manner. The lower opening is in screw connection with a lower adjusting end cover for closing the lower opening. The outer side wall of the bottom of the tank body is in screw connection with the inner side of the skirt portion. A gas line is arranged on the side wall of the base in a downward inclining manner. The gas linedeparts from the upper surface of the base and finally leads to the outer side of the base. According to the scheme, the gas line is arranged reasonably, on one hand, the situation that the gas lineis polluted and blocked can be prevented, on the other hand, the gas input amount and the gas output amount of the gas line can be adjusted, thus the different requirements of buffering pressure are met, and the suitability is improved greatly.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a flow regulating structure of an air storage tank used for a slow-down air cylinder. Background technique [0002] In some box-type structures, the cover plate is bulky and heavy. When the cover plate descends and closes, it is easy to pinch the user’s fingers or damage the keys when the cover plate is lowered and closed. This problem is especially for weaker users. prominent, which requires the use of a slow-down air tank for buffering the downward force of the cover plate, and the slow-down air tank often needs to use an air storage tank to provide air pressure for it. The existing air storage tanks have the following problems : First of all, the setting of the gas circuit is unreasonable, which will easily cause the blockage of the gas circuit due to pollution, and eventually lead to the inability to provide sufficient buffer pressure for the slow-down inflator; secondly, the air intak...

[0002] In some box-type structures, the cover plate is bulky and heavy. When the cover plate descends and closes, it is easy to pinch the user’s fingers or damage the keys when the cover plate is lowered and closed. This problem is especially for weaker users. prominent, which requires the use of a slow-down air tank for buffering the downward force of the cover plate, and the slow-down air tank often needs to use an air storage tank to provide air pressure for it. The existing air storage tanks have the following problems : First of all, the setting of the gas circuit is unreasonable, which will easily cause the blockage of the gas circuit due to pollution, and eventually lead to the inability to provide sufficient buffer pressure for the slow-down inflator; secondly, the air intake and outlet of the existing gas storage tank The flow rate cannot be adjusted according to the size of the required buffer force, resulting in poor adaptability of the existing slow-down inflator, which cannot meet the needs of different buffer pressures
