To achieve these goals, the technical solution used in the present invention is: the snap joint of a kind of underground coal mine controllable current break-make, comprise and introducing and the Explosion proof joint female realizing being connected with controlled power cutoff mechanism and Explosion proof joint male for cable, the water preventing space outerpace is installed in described Explosion proof joint female, dust and fuel gas enter the O RunddichtringO I of joint inside, the water preventing space outerpace is installed in described Explosion proof joint male, dust and fuel gas enter the O RunddichtringO II of joint inside, described Explosion proof joint female is connected with U-shaped pin I, described U-shaped pin I is connected with interior adapter sleeve, described Explosion proof joint male is connected with U-shaped pin II, and described U-shaped pin II is connected with outer adapter sleeve, in described interior adapter sleeve, O RunddichtringO III is installed, and interior adapter sleeve is connected with described outer adapter sleeve plug-in type.
Further, described outer adapter sleeve side is provided with the limit fastener limiting described Explosion proof joint female circular-rotation.
Further, the outer adapter sleeve installing described limit fastener the same side is installed the spacing ring that the described limit fastener of restriction moves axially.
Further, the outer adapter sleeve installing described limit fastener the same side is installed the spring being used for limit fastener and stretching.
Further, described interior adapter sleeve is embedded with the explosion-proof braid of Kevlar.
The invention has the beneficial effects as follows: this device adopts non-bolt two-stage explosion separation structure, use rotary buckle, the break-make of electric current can be realized, meet coal mine explosion-proof standard, help without the need to fastened tools, the manual rapid abutting joint operation at electrical apparatus for explosive atmospheres can be realized; Using multiple joint to carry out cascade, realize the break-make of electric current by wherein some joints, and the joint after this joint when not having deenergization, can realize wiring; This device inner chamber is lined with Kevlar flame retardant woven layer, reduces inner chamber flame proof gas volume, and can significantly improve flame proof ability.

Embodiment
Below in conjunction with accompanying drawing, invention is described further.
As shown in Figure 1: the snap joint of a kind of underground coal mine controllable current break-make, comprise and introducing and the Explosion proof joint female 1 realizing being connected with controlled power cutoff mechanism and Explosion proof joint male 13 for cable, in described Explosion proof joint female 1) in install and prevent the water of space outerpace, dust and fuel gas enter the O RunddichtringO I 3 of joint inside, the water preventing space outerpace is installed in described Explosion proof joint male 13, dust and fuel gas enter the O RunddichtringO II 10 of joint inside, described Explosion proof joint female 1 is connected with U-shaped pin I 4, described U-shaped pin I 4 is connected with interior adapter sleeve 5, described Explosion proof joint male 13 is connected with U-shaped pin II 12, and described U-shaped pin II 12 is connected with outer adapter sleeve 11, described interior adapter sleeve 5 inserts wherein on the right of outer adapter sleeve 11, and in utilizing, the boss of adapter sleeve 5 limits its distance moved right, interior adapter sleeve 5 is provided with O RunddichtringO III 9 to be connected with outer adapter sleeve 11, prevents outside water, dust and imflammable gas from entering joint inside.Spring of telling 8 is installed to outer adapter sleeve 11 from the left side, stretching for limit fastener 7.Described limit fastener 7 is installed to outer adapter sleeve 11 from the left side, the Explosion proof joint female 1 be connected on interior adapter sleeve 5 is carried out to the position-limiting action of circular-rotation.Described spacing ring 6 is installed to outer adapter sleeve 11 from the left side, moving axially of restriction limit fastener 7.Explosion proof joint female 1 is connected to interior adapter sleeve 5 from the left side, U-shaped pin I 4 is utilized to be fixed it, prevent the movement between Explosion proof joint female 1 and interior adapter sleeve 5, interior adapter sleeve 5 is equipped with O RunddichtringO III 9, prevent outside water, dust and imflammable gas from entering joint.Described interior adapter sleeve 5 is embedded with the explosion-proof braid 2 of Kevlar, reduces the amount of the inner fuel gas of joint, improve explosion-proof capabilities.
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 with Fig. 8: associating the faying face I place of a kind of underground coal mine of patent A1 formula quick Explosion proof joint female 1 with interior adapter sleeve 5, using quick plug to be connected with the quick plug in interior adapter sleeve 5 by the cable in Explosion proof joint female 1.At the faying face place of association patent a kind of underground coal mine A1 formula quick Explosion proof joint male 13 with outer adapter sleeve 11, employing reed-type contacts, when the groove in Explosion proof joint female 1 insert a enter limit fastener 7 time, as shown in Figure 5 and Figure 6, now joint inside cable is for off-position for the reed relative position in two face; Limit fastener 7 Compress Spring 9 is pulled to move right, the groove making the protruding c of limit fastener 7 exit Explosion proof joint female 1 inserts a, rotate female 45 °, the groove b of Explosion proof joint female 1 is made to aim at the projection of limit fastener 7, then limit fastener 7 is unclamped, limit fastener is moved to the left under the effect of spring 8 contractility, enter in the groove b of Explosion proof joint female 1, the rotation of restriction Explosion proof joint female 1, now joint inside is "on" position, and reed 8 relative position in two face as shown in Figure 7 and Figure 8.There is projection (the d place as in B-B cutaway view in Fig. 3) limit fastener 7 inside, is connected outside on adapter sleeve 11, prevents limit fastener 7 from rotating around adapter sleeve.
Because underground coal mine electric wire of powering is three-phase four-wire system, in order to prevent occurring the situation of wrong at the faying face of quick-fried joint female 1 and interior adapter sleeve 5 and Explosion proof joint male 13 with the faying face of outer adapter sleeve 11 in the process be connected, should connect in order when mounted, and inner quick plug and external lug should be combined closely, and there is certain relativity pretension force, prevent the situation owing to loosening between quick plug with joint and cause causing the quick plug when being energized to rotate the connection occurring contacting between bad or different cable in the rotation of reed place.
This joint, in the situation of being used alone, needs deenergization to connect; Deenergization is not needed namely by the break-make of the rotary control device electric current of this joint after connecting.If when cascade (as shown in Figure 9), when disconnecting one of them snap joint, can dismantle another one snap joint, cable connection is carried out at underground coal mine, now power supply does not disconnect, and can alleviate the labour intensity of workman, increase work efficiency.
