Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of bulge loop engagement formula quick negative joint, can improve the working efficiency of test bench, save test fuel oil, reduce labor strength, improve working environment, improve measuring stability, improve the turbidity test of fuel pump.
The technological scheme providing according to the utility model, the quick negative joint of bulge loop engagement formula comprises valve body, it is characterized in that: valve body madial wall is provided with interior limited step, valve outer surface is provided with outer support step, on outer support step, support the second spring, the sliding sleeve that is slidably mounted on valve outer surface is supported in the second spring upper end, and sliding sleeve inner side is provided with steel ball guiding reset sidewall; Valve body is provided with steel ball internal taper hole, in steel ball internal taper hole, is provided with steel ball; Valve body lower end connects swivel nut by internal thread, connects in swivel nut and is provided with inner support step; On inner support step, support the first spring, the spool being slidably connected in valve body is supported in the first spring upper end.
Further, between valve body and sliding sleeve, be provided with Steel Cable Baffle Ring.
Further, valve interior surface top is provided with multiple the first seal rings.
Further, the first seal ring is three.
Further, valve interior surface is provided with the second seal ring with being connected between swivel nut.
Further, spool is provided with sealing gasket.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, and plug is quick and easy, and utilization efficiency is high, and labor intensity is low, has improved the working efficiency of test bench; Joint inside, with self-styled spool, can close the test oil in low pressure fuel pipe, reduces the waste to test oil, saves test fuel oil; Reduce air and enter pump and test oil circuit inside, the stability that reduction is tested pump and the impact of accuracy, improve working environment, improves measuring stability, improves the turbidity test of fuel pump.

Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises valve body 1, and valve body 1 outer surface is provided with outer support step 10, supports the second spring 4 on outer support step 10, the sliding sleeve 6 that is slidably mounted on valve body 1 outer surface is supported in the second spring 4 upper ends, and sliding sleeve 6 inner sides are provided with steel ball guiding reset sidewall 16.Valve body 1 is provided with steel ball internal taper hole 13, is provided with steel ball 12 in steel ball internal taper hole 13.In the time connecting another quick male connector, sliding sleeve 6 moves reset under the second spring 4 thrusts, steel ball 12 moves inward under the thrust of the steel ball guiding reset sidewall 16 of sliding sleeve 6, thereby protrude from the inner of steel ball internal taper hole 13, block the engagement boss of another quick male connector, valve body 1 madial wall is provided with interior limited step 15, interior limited step 15 and the common engagement boss that clamps another quick male connector of steel ball 12, thus two rapid pipe joints are self-locking in together.Between described valve body 1 and sliding sleeve 6, be provided with Steel Cable Baffle Ring 7 spacing.
Valve body 1 lower end connects swivel nut 3 by internal thread, connects in swivel nut 3 and is provided with inner support step 11.On inner support step 11, support the first spring 2, the first spring 2 upper ends supports and be slidably connected at the spool 9 that plays self-tightening in valve body 1.
Described valve body 1 internal surface top is provided with multiple the first seal rings 5 for another rapid pipe joint of being tightly connected, and in embodiment as shown in Figure 1, the first seal ring 5 is three.
Described valve body 1 internal surface be connected between swivel nut 3, be provided with the second seal ring 14, the second seal rings 14 for sealed valve body 1 be connected between swivel nut 3.
Described spool 9 is provided with the sealing gasket 8 for sealed valve body 1 inner chamber.
Working principle of the present utility model is: in the time of work, between valve body 1 and another rapid pipe joint, realized and being tightly connected by multiple the first seal rings 5.After pulling sliding sleeve 6 to be connected with another rapid pipe joint, unclamp sliding sleeve 6 downwards, sliding sleeve 6 can reset under the effect of the second spring 4.In the process resetting, promote steel ball 12, steel ball 12 can be under the effect of sliding sleeve 6, to the medial movement of valve body 1, sliding sleeve 6 compresses steel ball 12 again, steel ball 12 is nested and protrude from the inner hole surface of valve body 1, and be connected with the annular boss formation engagement of another rapid pipe joint, two rapid pipe joints are self-locking in together.In the time extracting, only need pulled down sliding sleeve 6 again, keep sliding sleeve 6 constant in lower position, the whole valve body 1 of pulled down again, at this moment the steel ball 12 being compressed by sliding sleeve 6 exits the endoporus of valve body 1 under the effect of the radial force of the fillet of the annular boss of another rapid pipe joint, abdicate enough positions to another rapid pipe joint, this pair of joint can freely be separated.When separation, spool 9 can, under the effect of the first spring 2, automatically reset, and realizes self-isolation.
