Description

Technical Field

[0001] The utility model relates to the field of building accessories, in particular to an air nail gun capable of reducing nail jamming failures. Background Art

[0002] A stuck nail in an air nail gun may cause damage to its internal parts, affecting its normal function and service life. During operation, if a nail is stuck in an air nail gun, it may suddenly release energy and cause injury to the operator, especially under irregular operation, such as dry firing, which is more likely to cause injury. A stuck air nail gun may cause instability in the workplace and increase the risk of injury to other workers.

[0003] In the prior art, the top nail guide groove of the air nail gun is in high-speed contact and friction with the air nail during use. When it is used dry for a long time without lubrication, the inner wall of the top nail guide groove will cause friction to produce fine burrs, which will cause the air nail gun to jam. Usually, the top nail guide groove of the air nail gun is oiled and maintained by the user after each use. Manual oiling and maintenance is prone to forgetting or laziness and not performing maintenance according to the rated number of uses, which causes the inner wall of the top nail guide groove to dry grind and jam the nail.

[0006] Furthermore, on the upper right side of the main gun body is a nail pushing platform with a nail pushing guide groove on the upper surface, the depth of the nail pushing guide groove of the nail pushing platform is equal to the thickness of a single air nail, and below the nail pushing platform is a magazine for automatically feeding nails upwards, and the top cover of the nail pushing platform is provided with a groove pressure plate, the inside of the gun body on the left side of the main gun body is a cylinder cavity, and a pneumatic rod block that slides left and right is provided in the cylinder cavity, and a round shaft-shaped oil pushing rod is provided in the center of the right side surface of the cylinder cavity, and an oil filling tank is fixedly provided on the top of the gun body on the left side of the main gun body.

[0007] Furthermore, the main body of the oil filling tank is an oil storage tank body with an L-shaped bracket on the left side. The oil storage tank body is a hollow cavity, and the oil storage tank body is filled with high-fluidity lubricating oil. A removable oil tank plug is provided at the top right side of the oil storage tank body, and an oil filling port that penetrates into the internal cavity is provided at the bottom of the left L-shaped bracket of the oil storage tank body. The bottom surface of the left L-shaped bracket of the oil storage tank body fits with the upper surface of the top nail platform of the main gun body.
