New description: [New technical field] This creation department is about the construction of a quick joint, especially the first retaining wall is bent outward by the front end of the body, and the front end of the inner edge of the collar is bent inward. There is a second retaining wall, and the inner ring of the collar is provided with a blocking portion, so as to block the intrusion of impurities such as dust and grease on the outside, and hinder the movement of the collar and the ball. [Prior Art] According to the quick connector structure generally used, as shown in the fourth figure, the body is provided with a body (A), and the front end of the body (A) is provided with a card slot (A1), the card slot ( A1) The inner card has a buckle (A2), and a plurality of through holes (A3) are arranged at the rear end of the card slot (A1) of the body (A), and the ball (A3) is provided with a ball ( A4), an elastic member (A5) is sleeved on the outer edge of the body (A), and a ring (A6) is placed on the outer edge of the body (A), thereby pressing the collar (A6) to press the elastic member. (A5), for the male hoe (B) can be inserted into the body (A), and by the elastic restoring force of the elastic member (A5), the collar (A6) can be pushed back to the fixed position 10, and then pressed The ball (A4) in the through hole (A3) is inserted into the card slot (B1) of the male connector (B) for connection and assembly positioning. However, due to the configuration, the body (A) There is a gap between the collar and the collar (A6), and the buckle (A2) and the ball (A4) are exposed, causing impurities such as dust and grease, which are easily separated by the gap between the body (A) and the collar (A6). Intrusion, resulting in the formation of use Obstruction, even hindering the movement of the collar (A6) and the ball (A4), and it uses the buckle (A2) to prevent the body (A) from coming off the collar (A6), because the buckle (A2) is assembled It is more difficult, so it is not ideal for use. [New content] M325425 - In view of the structure of the conventional quick joints, it is easy to be invaded by impurities such as ash and grease, which hinders the movement of the collar and the ball, and the assembly of the buckle is difficult. The utility model relates to a structure for providing a quick joint, which is provided with a body, the front end of which is bent outwardly and has a first supporting wall extending vertically, and the main body is provided with a through hole at the end ring of the first retaining wall, and the through hole is provided therein. There is a beaded beak and a bead is arranged at the middle of the outer edge of the outer edge of the body, and an elastic element is disposed on the front end of the tenon and a connecting portion is screwed to the rear end of the body; the collar is lubricated At the outer edge of the body, the front end of the inner edge of the collar is bent inwardly with a second retaining wall extending vertically, and the collar is provided with a groove at the rear end of the second retaining wall, and the rear ring of the groove The blocking portion is disposed such that the elastic element of the body is located between the tenon and the blocking portion; the air guiding seat is disposed in the body, and the air guiding seat has no air passage. The body system is provided with an air guide seat, and an air passage is formed in the air guide seat. This creation has the following advantages: · 1 1. This creation system can block the movement of the second retaining wall of the collar by the first retaining wall of the body to prevent the collar from coming off the body, thereby replacing the conventional buckle. It is easy to assemble and easy to assemble and easy to disassemble and replace. 2. This creation is based on the fact that the first retaining wall of the main body and the second retaining wall of the collar reciprocate each other and block the barrier, so that impurities such as dust and grease can not pass between the body and the collar. The gap is invaded to avoid the effect of impurities preventing the movement of the collar and the ball. [Embodiment] First, as shown in the first figure, this creation mainly includes the body • M325425 • (1), collar (2) and air bearing seat (3), where ·· body (1), The utility model is hollow, and the front end is outwardly bent with a first retaining wall (11) extending at a width of ninety degrees, and the main body (丨) is provided with a plurality of through holes at the end ring after the first retaining wall (11). 12), the through holes (12) are provided with a ball (13), and a middle portion of the outer edge of the body (丨) is provided with a tenon (14), and the end of the tenon (14) is sleeved. An elastic member (15) is disposed, and a connecting portion (16) is screwed to the rear end of the body (1). _ collar (2), which is sleeved on the outer edge of the body (1), and the front end of the inner edge of the collar (2) is bent inwardly with a second retaining wall (21) extending vertically at ninety degrees. The second retaining wall (21) is blocked by the first retaining wall (11) of the body (1) to prevent the collar (2) from coming off the body (1), which can replace the function of the conventional buckle. The collar (2) is provided with a recess (22) at the rear connecting ring of the first broadcast wall (21), and a retaining portion (23) is disposed at the rear connecting ring of the recess (22). The elastic member (15) is located between the tenon (14) and the blocking portion (23). The air guiding seat (3) is disposed in the body (1), and the air guiding seat (3) is pierced with an air passage (31). When used, as shown in the second and third figures, the creation system can be used with the male connector (C). The outer edge of the male connector (C) is provided with the engine (C1), and the Gansu first body (1) The outer edge of the collar (2) is pushed back, and the (23) of the collar (2) compresses the elastic member (15), and when the male connector (c) is inserted into the body, the body can be pressed (1) The ball (13) in the through hole (12) is outwardly and retracted into the groove (22) of the collar (2). When the release collar (2) no longer compresses the elastic member (15), The elastic element (15) pushes the retaining portion (23) of the collar (2) by its elastic restoring force to return the collar (2) to the positioning, and utilizes the resistance of the collar (2) M325425 (23) The ball (13) in the through hole (12) can be pushed to be in the card slot (C1) of the male connector (c), and the body and the male connector (c) are connected and assembled, and The other end of the male connector (c) can be connected to the gas cylinder to guide the gas through the body (1), and then through the air passage (31) of the air conduction seat (3), into the device to be inflated; From the first wall of the body (丨) and the collar (2) The second retaining walls (21) overlap each other, and the blocking effect of the blocking portion (2 3 ) can prevent foreign matter such as dust and grease from being invaded, thereby preventing impurities from obstructing the movement of the collar and the ball. At the same time, when the body (1) is separated from the male connector (C), the first retaining wall (11) of the body (1) and the second wall (2丨) of the collar (2) can still be overlapped. 'and the blocking function of the blocking portion (23), so that impurities such as dust and grease on the outside cannot enter through the gap between the body (1) and the collar (2), so as to prevent the impurities from hindering the movement of the collar and the ball.
