Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air leakage-proof air compressor. Background Art

[0002] An air compressor is a device used to compress air to a high pressure and is commonly used in a variety of industrial and commercial applications. They primarily increase the pressure of a gas through mechanical compression, thereby providing compressed air for power, tool operation, pneumatic equipment, etc.

If the connection is loose or not tight, it can lead to gas leaks in the compressed air system. This leakage not only affects system efficiency and performance but can also lead to energy waste and operational safety issues. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figures 1 to 6 The utility model provides a technical solution: an air leakage-proof air compressor, comprising a compressor tank body 1, an exhaust pipe 2 connected to the compressor tank body 1, and an exhaust valve 3 detachably mounted on the top of the exhaust pipe 2. The exhaust pipe 2 is provided with a support groove 203, an internal thread groove 201 and a ventilation groove 202 from top to bottom. The lower end of the exhaust valve 3 has an external thread end 301, and the lower end of the external thread end 301 is threadedly inserted into the internal thread groove 201. The inner diameter of the internal thread groove 201 is smaller than the inner diameter of the support groove 203; a rubber ring 4 is sleeved on the external thread end 301. When the exhaust valve 3 is installed, the rubber ring 4 is arranged in the support groove 203, and the upper end of the rubber ring 4 is pressed and fixed by the exhaust valve 3. The side wall of the exhaust valve 3 is fixedly connected with a positioning ring 5, and the side wall of the exhaust pipe 2 is fixedly connected with a support plate 6. The support plate 6 is fixedly connected with an insertion rod 8. A positioning rod 9 is movably sleeved on the insertion rod 8, and the upper end of the positioning rod 9 is movably inserted into the interior of the positioning ring 5.

During the operation, safety precautions will be broadcast at regular intervals. The above functions can be achieved through existing technologies and will not be elaborated on.

[0026] In this application, the exhaust valve 3 is installed on the exhaust pipe 2, and the sealing between the two can be increased by setting the rubber ring 4, further preventing gas leakage, and by loosening the bolt 10, the positioning rod 9 moves upward under the elastic force of the spring 7, so that the upper end of the positioning rod 9 is inserted into the interior of the positioning ring 5, thereby achieving the purpose of locking the exhaust valve 3, ensuring that the exhaust valve 3 maintains a stable position during operation, preventing the exhaust valve 3 from rotating loose and causing leakage, avoiding energy waste and improving operational safety.

[0027] Specifically, the positioning rod 9 is in the shape of a round rod as a whole, and there is a circular socket inside the positioning ring 5. The positioning rod 9 and the positioning ring 5 are transitionally matched to ensure a certain tightness between the two, which can achieve the purpose of locking the exhaust valve 3; this design ensures that the exhaust valve 3 will not rotate or loosen during operation, thereby effectively preventing gas leakage.

[0028] A rectangular slot is provided at the bottom of the positioning rod 9, and the insertion rod 8 is a rectangular rod, so that the insertion rod 8 can guide the positioning rod 9 in a straight line, so that the positioning rod 9 can only move in the vertical direction.
