Description
Technical Field
The utility model relates to a gas spring, in particular to a gas spring capable of being inflated and deflated.
Background
The gas spring is through aerifing to the tail stifled to fill into high-pressure gas in to the cylinder, the gas inlet structure that aerifys of conventional gas spring is very complicated, including components and parts such as spring, so, under the condition that aerifys inlet structure and damage, it is very difficult to change components and parts.
In conclusion, how to realize simple inflation and deflation of the gas spring is a problem which needs to be solved urgently by researchers in the field.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: how to realize simple inflation and deflation of the gas spring;
in order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model relates to a gas spring capable of being inflated and deflated, which comprises: a cylinder barrel; the tail plug is fixed at the bottom in the cylinder barrel; the tail plug is provided with an air inlet cavity and an air inlet channel communicated with the cylinder barrel and the air inlet cavity; the tail plug comprises an inclined wall and a vertical wall, and the inclined wall and the vertical wall form a groove body sleeved with the sealing ring; the end part of the air inlet channel is arranged on the groove body and is sealed by a sealing ring;
in the scheme, gas is filled into the cylinder barrel through the gas inlet cavity and the gas inlet channel of the tail plug, the sealing ring is sleeved on a groove body formed by the inclined wall and provided with the gas inlet channel sealed by the inner sealing ring, and the end part of the tail plug is provided with a vertical wall;
when the cylinder barrel is inflated, the sealing ring deforms under the impact of air flow, a gap is formed between the sealing ring and the groove body, and the air flow enters the cylinder barrel from the gap, so that the air pressure of the cylinder barrel is increased;
when no longer filling gas into the cylinder, the sealing washer can be compressed to the high pressure in the cylinder, makes it laminate on the cell body, stops up the tip of inlet channel, prevents that gas from flowing.
When the gas needs to be discharged, a gap is formed between the sealing ring and the groove body through external force (for example, the sealing ring is pulled in the cylinder body or punctured along the gas inlet channel), so that the gas can sequentially pass through the gas inlet channel and the gas inlet cavity to be discharged.
In order to explain how the tail plug is fixed at the bottom in the cylinder barrel, the tail plug is provided with an annular groove for placing a second sealing ring; the second sealing ring seals the inner wall of the cylinder barrel and the tail plug; the cylinder barrel is inwards provided with a limiting ring for deforming the second sealing ring;
the second sealing ring realizes the sealing connection between the tail plug and the inner wall of the cylinder barrel, and the limiting ring is inwards concave, so that the second sealing ring is deformed, and the cylinder barrel and the tail plug are in sealing connection.
The utility model has the beneficial effects that: the utility model relates to an air spring capable of inflating and deflating, which is characterized in that gas is inflated into a cylinder barrel through a gas inlet cavity and a gas inlet channel of a tail plug, a sealing ring is sleeved on a groove body formed by a vertical wall and an inclined wall at the end part of the tail plug, and the groove body is provided with the gas inlet channel sealed by an inner sealing ring, so that the simple inflation and deflation of the air spring are realized.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a cross-sectional view of the structure of the present invention;
FIG. 2 is a cross-sectional view from another perspective of the present invention;
in the figure: 1-cylinder barrel, 2-tail plug, 3-air inlet cavity, 4-air inlet channel, 5-inclined wall, 6-vertical wall, 7-sealing ring, 8-groove body, 9-second sealing ring and 10-spacing ring.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1-2, the present invention is an inflatable and deflatable gas spring comprising: a cylinder barrel 1; the tail plug 2 is fixed at the bottom in the cylinder barrel 1; the tail plug 2 is provided with an air inlet cavity 3 and an air inlet channel 4 which is communicated with the cylinder barrel 1 and the air inlet cavity 3; the tail plug 2 comprises an inclined wall 5 and a vertical wall 6, and the inclined wall 5 and the vertical wall 6 form a groove body 8 sleeved with a sealing ring 7; the end part of the air inlet channel is arranged on the groove body and is sealed by a sealing ring;
in the scheme, gas is filled into the cylinder barrel through the gas inlet cavity and the gas inlet channel of the tail plug, the sealing ring is sleeved on a groove body formed by the inclined wall and provided with the gas inlet channel sealed by the inner sealing ring, and the end part of the tail plug is provided with a vertical wall;
when the cylinder barrel is inflated, the sealing ring deforms under the impact of air flow, a gap is formed between the sealing ring and the groove body, and the air flow enters the cylinder barrel from the gap, so that the air pressure of the cylinder barrel is increased;
when no longer filling gas into the cylinder, the sealing washer can be compressed to the high pressure in the cylinder, makes it laminate on the cell body, stops up the tip of inlet channel, prevents that gas from flowing.
When the gas needs to be discharged, a gap is formed between the sealing ring and the groove body through external force (for example, the sealing ring is pulled in the cylinder body or punctured along the gas inlet channel), so that the gas can sequentially pass through the gas inlet channel and the gas inlet cavity to be discharged.
As shown in fig. 1-2, in order to illustrate how the tail plug is fixed on the inner bottom of the cylinder barrel, the utility model adopts the tail plug 2 with an annular groove for placing a second sealing ring 9; the second sealing ring 9 seals the inner wall of the cylinder barrel 1 and the tail plug 2; the cylinder barrel 1 is inwards concavely provided with a limiting ring 10 for deforming the second sealing ring 9;
the second sealing ring realizes the sealing connection between the tail plug and the inner wall of the cylinder barrel, and the limiting ring is inwards concave, so that the second sealing ring is deformed, and the cylinder barrel and the tail plug are in sealing connection.
The utility model relates to an air spring capable of inflating and deflating, which is characterized in that gas is inflated into a cylinder barrel through a gas inlet cavity and a gas inlet channel of a tail plug, a sealing ring is sleeved on a groove body formed by a vertical wall and an inclined wall at the end part of the tail plug, and the groove body is provided with the gas inlet channel sealed by an inner sealing ring, so that the simple inflation and deflation of the air spring are realized.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model.
