Problems solved by technology

[0008] For the conventional quick joint combination, the sealing structure design of the ball and the leak-proof device cannot achieve a complete leak-proof effect, and the wear and tear between the ball and the leak-proof device due to mutual movement will gradually lose the leak-proof effect. The gap caused by wear cannot be filled, resulting in the loss of effectiveness of the leak-proof device and the problem of reduced service life. The main purpose of the present invention is to provide a quick connector for the air inlet of an air tool, which has the ability to fill the wear gap, and the leak-proof device and The tightness of the ball is good, so that the male joint can be completely sealed and leak-proof at any angle or position.

Embodiment Construction

[0031] As shown in Figure 1 and Figure 2, the quick connector of the air inlet of the pneumatic tool provided by the present invention mainly includes:

[0032] A pneumatic tool 40, the bottom of the pneumatic tool 40 is provided with a spring hole 41, and an elastic component 50 is placed in it, and one end of the elastic component 50 abuts against a leak-proof piston 60, and the bottom port of the pneumatic tool 40 is provided with an inner screw hole 42 .

[0033] A leak-proof piston 60, which is made of soft material, is covered with an O-ring 61 to seal the leak-proof piston 60 and the spring hole 41, and one end of the leak-proof piston 60 is set to gradually expand from the outside to the inside. The tapered hole 62 is increased (smaller on the outside and larger on the inside), and a circular socket 63 is provided at the other port. The arc curvature of the circular socket 63 is the same as that of the sphere 71 of the male joint 70 .

[0034] A ball 71 at one end of ...

Abstract

The invention comprises a pneumatic tool, a leakproof piston, a male joint and a bolt. At the bottom port of the pneumatic tool is disposed an internal screw hole. At the bottom of the pneumatic tool is disposed a spring-holding hole, in which is held an elastic element. One end of the leakproof piston contacts with an elastic element and the other end is connected with the male joint. One spherical end of the male joint contacts with the leakproof piston and the other end passes through the bolt. The bolt is fixed in the internal screw hole at the bottom port of the pneumatic tool.

Description

technical field [0001] The invention relates to an air inlet of a pneumatic tool, in particular to a combination of an air inlet of a pneumatic tool and a male joint of a quick connector so that it can be directly and quickly fitted with a female connector of the quick connector, and has 360-degree rotation and a suitable Angular deflection function. Background technique [0002] Commonly used pneumatic tools are shown in Figures 4 to 7, including an air dust blowing gun 11 (as shown in Figure 4), a pneumatic grinder 12 (as shown in Figure 5) or a paint spray gun 13 (as shown in Figure 6). ) ... etc., the air inlet 14 at the end must be screwed with a male connector 15 of a quick connector, and the male connector 15 can be quickly fitted or quickly disengaged with the female connector 17 screwed on the air pipeline 16 (as shown in Figure 7 shown). Generally, any kind of pneumatic tool often needs to be rotated when it is used, and it often happens that the air pipeline 16 ...
