By said structure, be appreciated that a kind of Quick Connect Kit the utility model proposes, by inner sleeve and overcoat, match, the lower end of inner sleeve can connect mutually by screw thread and the first link, and the upper end of inner sleeve is by ball and the second link clamping.Ball can radially move interior putting, the second link can be designed to axle sleeve form, the groove adapting at its outer wall setting and ball, when overcoat Compress Spring moves to inner sleeve lower end, the ball that the ball inside putting can be retracted in overcoat is given up the throne in groove, now the link with groove can be inserted in inner sleeve, when spring reset, described ball is to the shaft core direction skew of inner sleeve, and the ball of protrusion can be connected in the groove on the second link, realizes fast and connecting.During dismounting, also only need to pull overcoat, Compress Spring again, the second link can easily be extracted from inner sleeve, realizes fast two connection and fractionations between link.
For stressed evenly and be convenient to rotation, described inner sleeve and overcoat are cylindrical shape.
Overcoat is put to ejection from interior when preventing spring reset, on the outer wall of interior set upper side, be provided with back-up ring.
In order better to realize the cooperation between inner sleeve and overcoat, be convenient to the installation of spring simultaneously, boss on described outer wall of inside race is arranged to circular, inwall at described overcoat is also provided with circular flange collar, while putting in overcoat is socketed in, the boss on outer wall of inside race and the flange collar on outer casing inner wall surround the installation chamber of described spring.
For the ease of gripping, the outer surface of described overcoat is set to have the non slip surface of concavo-convex profile, stressed like this convenience, and installation and removal are also very easy to.
Remarkable result of the present utility model is: simple in structure, easy to assembly, utilize this linkage structure, and can realize quick connection and the dismounting of two links, very easy to use, improved working efficiency.
Accompanying drawing explanation
Fig. 1 is the assembled relation figure of each component of the utility model;
Fig. 2 is structural representation of the present utility model under spring reset state;
Fig. 3 is structural representation of the present utility model under spring-compressed state;
Fig. 4 is use phase diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1-Figure 3, a kind of Quick Connect Kit, comprise inner sleeve 1, spring 2, overcoat 3 and ball 4, inner sleeve 1 and overcoat 3 are cylindrical shape, the lower end of inner sleeve 1 is provided with internal thread, on the sleeve of inner sleeve 1 upper end, according to annular, be embedded with many balls 4, the quantity of ball 4 can arrange 5-10 according to the size of inner sleeve 1, overcoat 3 is socketed in inner sleeve 1, these overcoat 3 one end connect by spring 2 and the boss of inner sleeve 1 outer wall, the inwall of overcoat 3 the other ends offers the ball groove of giving up the throne, when overcoat 3 Compress Springs 2 move to inner sleeve 1 lower end, the ball that ball 4 in inner sleeve 1 can be retracted in overcoat 3 is given up the throne in groove, when spring 2 resets, described ball 4 is to the shaft core direction skew of inner sleeve 1.
As seen in Figure 3, overcoat 3 is ejected when preventing that spring 2 from resetting, on the outer wall of described inner sleeve 1 upper end, be provided with back-up ring 5.
Referring to Fig. 2, Fig. 3, can find out, in specific implementation process, boss on described inner sleeve 1 outer wall is arranged to circular, inwall at described overcoat 3 is also provided with circular flange collar, when overcoat 3 is socketed in inner sleeve 1, flange collar on boss on inner sleeve 1 outer wall and overcoat 3 inwalls surrounds the installation chamber of described spring 2, during assembling, first spring 2 is socketed on the outer wall of inner sleeve 1, overcoat 3 is enclosed within inner sleeve 1, spring 2 is inserted in the installation chamber that boss on inner sleeve 1 outer wall and the flange collar on overcoat 3 inwalls surround automatically again.
For the ease of the gripping of overcoat 3 and stressed, the outer surface of described overcoat 3 is set to have the non slip surface of concavo-convex profile.
