Drawings
FIG. 1 is a half-sectional view of the present invention;
fig. 2 is a schematic structural view of part C of fig. 1.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
A detachable connection fitting, as illustrated in figures 1 to 2, comprises a first body 1, a second body 2, a sealing assembly 4, a thrust pressure ring 12 and an anti-pull ring 14. The diameter of the first body 1 is larger than that of the second body 2, and one end of the second body 2 is inserted into the first body 1. The connection end portion of the first body 1 is provided with at least two continuous inclined surfaces A, B, and the inclined surface A, B means an upward inclination with respect to the horizontal direction. Two the sealed chamber 3 is constituteed with the outer wall of second body 2 to the inclined plane, seal assembly 4 sets up in the sealed chamber. The first body 1 is connected with a fastening screw 5, the second body 2 is connected with a fastening nut 6, and the fastening screw 5 is connected with the fastening nut 6 in a matched mode. The fastening nut 6 forms a fastening cavity 13 with the outer wall of the second body 2. The pushing pressing ring 12 is sleeved with the second body 2 and arranged in the fastening cavity. One end face of the pushing pressing ring 12 is connected with the sealing component in a jacking mode, and the other end face of the pushing pressing ring is connected with the end face of the fastening cavity in a jacking mode. The outer wall of the second body 2 is provided with a clamping groove, the anti-pulling ring 14 is clamped in the clamping groove, and the anti-pulling ring 14 is a rigid ring. The fastening nut 6 is provided with a limiting groove 15 for limiting the movement of the anti-pulling ring 14, the limiting groove 15 is formed by matching an inclined surface with the outer wall of the second body 2, the limiting groove 15 is wedge-shaped, and one end of the limiting groove is communicated with the fastening cavity 13. When the anti-pulling ring is arranged at the large end of the limiting groove 15, the anti-pulling ring is not contacted with the groove wall of the limiting groove 15, and when the anti-pulling ring 14 moves to the small end of the limiting groove 15, the anti-pulling ring is abutted against the groove wall. When the pressure of medium is too big in the pipe fitting, the second body can drive anti-pulling ring 14 and remove to the tip by the main aspects of spacing groove 15, makes anti-pulling ring 14 and 15 butts of spacing groove to prevent that second body and first body from breaking away from each other.
