Above-mentioned prevent pipeline quick-operation joint that vibration pine takes off, locking subassembly still is equipped with the adjusting shim, and the adjusting shim suit is in female end, and the adjusting shim is located between lock nut and the snap ring.

Above-mentioned prevent pipeline quick-operation joint that vibration pine takes off, locking subassembly still is equipped with the second snap ring, still is equipped with the second draw-in groove on the female end, and the second draw-in groove is located the inboard of locknut end, and the second snap ring inlays the dress in the draw-in groove, and the second snap ring is spacing to locknut's inboard axial.

The periphery of the locknut is provided with a rotating plane.

The utility model discloses to solving the lock sleeve and receiving the not hard up problem of vibration, having carried out structural improvement to the quick-witted meet of pipe fitting, add locking subassembly, utilize locking subassembly restriction lock sleeve to take place the displacement to even guaranteed that the lock sleeve also can not become flexible in the operational environment of strong vibration. The utility model discloses when keeping the swift dismouting characteristics of pipeline quick-operation joint, effectively avoid the not hard up transposition of lock sleeve, connect the reliability and improve greatly, be fit for being used for having the pipeline of vibration.

FIG. 2 is a left side view of FIG. 1;

FIG. 3 is a schematic structural view of the lock sleeve;

FIG. 4 is a schematic structural view of the female end;

fig. 5 is a schematic structural view of the locknut.

The reference numbers in the figures are: 1. the locking device comprises a male end, 2, a locking sleeve, 2-1, a locking section, 3, a sealing ring, 4, a female end, 4-1, a clamping groove, 4-2, a second clamping groove, 5, a locknut, 5-1, a rotating plane, 6, an adjusting gasket, 7, a first clamping ring, 8 and a second clamping ring.

Detailed Description

Referring to fig. 1 and 2, the present invention includes a male end 1, a female end 4 and a lock sleeve 2. The male end is provided with a boss, the female end is provided with a concave surface which is matched with the convex-concave surface, a sealing ring 3 is arranged between the male end and the female end, after the boss of the male end is inserted into the concave surface of the female end, a lock sleeve spanner is rotated, and the male end and the female end are locked by an inclined surface arranged on the lock sleeve. For the quick-operation joint who avoids being arranged in the pipeline of vibration takes place the problem that the transposition pine takes off in the use of lock sleeve, the utility model designs a locking subassembly, locking subassembly includes locknut 5, adjusting shim 6 and first snap ring 7, second snap ring 8.

Referring to fig. 1 and 3-5, the lock sleeve is provided with a locking section 2-1 which extends and lengthens towards the direction of the female end, and the locking section is provided with external threads. The locknut is sleeved outside the female end and is screwed with the external thread on the locking section. The female end is provided with a first clamping groove 4-1 and a second clamping groove 4-2, the first clamping groove is positioned on the outer side (the right side of the figure) of the end head of the locknut, a first clamping ring is embedded in the first clamping groove, and the first clamping ring is used for axially limiting the right side of the locknut. The adjusting gasket is sleeved on the female end and located between the locknut and the first clamping ring, and the thickness of the adjusting gasket is matched with the distance from the first clamping ring to the end face of the locknut. Set up the effect that adjusting shim played the clearance between compensation lock nut and the snap ring on the one hand, on the other hand can also improve the support intensity of first snap ring. The second clamping groove 4-2 is located on the inner side (left side) of the end of the locknut, the second clamping ring 8 is embedded in the second clamping groove, and the second clamping ring axially limits the left side of the locknut. The first snap ring and the second snap ring are both split rings. The outline of the locknut is approximately square, and the periphery of the locknut is provided with a rotating plane 5-1 which is convenient to disassemble and assemble.

When the utility model is used, the female end, the male end, the lock sleeve and the sealing ring are firstly connected, after the lock sleeve is locked, the second snap ring is installed, the locknut is sleeved, the locknut and the lock sleeve are screwed, after the locknut is locked to be tightly attached to the second snap ring, the locknut is screwed continuously to pull the lock sleeve to be further connected and fastened with the male end, and the sealing ring is further compressed, so that the sealing property is well ensured; after the locknut is installed, the adjusting gasket with the proper thickness is selected, and the adjusting gasket and the first clamping ring are sequentially installed, so that the axial displacement on the right side of the locknut is limited by the adjusting gasket and the first clamping ring, the lock sleeve cannot generate transposition and displacement, and the locking function of the lock sleeve is guaranteed. When the quick connector is disassembled, the first clamping ring, the adjusting gasket, the locknut and the second clamping ring are sequentially disassembled, the lock sleeve is unscrewed, and the quick connector can be disassembled. Above-mentioned structure, easy dismounting is swift simple, has good locking and sealed effect.
