Description

Technical Field

[0001] The utility model relates to the technical field of air compressor pipeline protection equipment, in particular to a line pipeline protection device for an air compressor. Background Art

[0002] Air compressor is the abbreviation of air compressor, which is usually used in combination with air pipe fittings and compressed gas tanks. The air compressor is used to compress air and store it in the gas tank for standby use. The inventors found that the air pipe connecting the air compressor and the gas tank generally adopts PU high-pressure pipe. Even if it has good anti-bending performance, when the distance between the air compressor and the gas tank is small or the air pipe is excessively bent due to winding, the air pipe will be closed at the bending position due to the bending amplitude exceeding the threshold, and creases will appear at the bending position, which also causes the strength of the crease position of the air pipe to be damaged, and there is a risk of pipe body cracking under high pressure. Therefore, those skilled in the art hereby propose a line pipeline protection device for air compressors. Utility Model Content

[0023] Embodiment, a better technical solution for a line pipeline protection device for an air compressor.

[0024] Refer to the instruction manual Figure 1 As shown; including an air compressor 1 and a compressed gas tank 3, an air pipe 25 is connected between the output end of the air compressor 1 and the input end of the compressed gas tank 3, and the outer ring surface of the air pipe 25 is wrapped with a pipeline protection sleeve 2; refer to the attached manual Figure 4 As shown; the pipeline protection sleeve 2 includes a PVC sleeve 21 wrapped around the outer surface of the air pipe 25, four stainless steel bars 23 embedded and fixed on the wall of the PVC sleeve 21 around the axis of the PVC sleeve 21, and 60-80 metal rings 24 fixed on the outer surface of the stainless steel bar 23 in a linear array along the axis of the PVC sleeve 21.

[0025] Refer to the instruction manual Figure 4 As shown; four grooves 22 are equidistantly formed on the wall of the PVC sleeve 21, and the outer surface of the stainless steel strip 23 is fixedly connected to the inner side wall of the groove 22 by an adhesive, the inner surface of the metal ring 24 is fixedly connected to the outer surface of the stainless steel strip 23 outside the groove 22, the length of the PVC sleeve 21 and the stainless steel strip 23 is equal to the length of the air pipe 25, and the metal rings 24 are equidistantly distributed on the outer surface of the PVC sleeve 21.

[0026] Refer to the instruction manual Figure 4As shown; the side walls around the inner cavity of the PVC sleeve 21 are fixedly connected to the outer ring surface of the air pipe 25 by adhesive, and the wall thickness of the PVC sleeve 21 is twice the wall thickness of the air pipe 25. The spacing between the metal rings 24 is 0.7cm-1.0cm, which is used for the metal rings 24 to contact each other to prevent the bending from continuing when the bending amplitude of the PVC sleeve 21 and the air pipe 25 is too large. An air input connector 5 is provided on the front side surface of the compressed gas tank 3, and three supporting legs 6 are fixed in a circular array on the bottom surface of the compressed gas tank 3.

[0027] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0028] When the air compressor 1 delivers compressed air to the compressed gas tank 3 through the air pipe 25, to prevent the air compressor 1 and the compressed gas tank 3 from being too close and causing the air pipe 25 to be bent too much, the PVC sleeve 21 uses its own toughness to support the air pipe 25, and the four stainless steel bars 23 on the wall of the PVC sleeve 21 limit the bending range of the PVC sleeve 21 and the air pipe 25 due to their own rigidity. After the bending exceeds the limit of the stainless steel bars 23, one side of the metal ring 24 at the bending position gathers together along the bending direction, and the mutual contact between the metal rings 24 is used to prevent the bending from continuing. It prevents the air pipe 25 from being bent too much and causing partial inward contraction and closing the pipeline, and prevents the air pipe 25 from having creases at the bending position that affect the overall strength, and there is a risk of cracking at the crease position.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
