Specific embodiment
Below in conjunction with Figure of description, the invention will be described in further detail, and provides specific embodiment.
As shown in Figs. 1-2, a kind of quick coupling of the present invention, including connector, sleeve, spring, circlip, steel ball, sleeve set
Setting is connect on connector outer wall and the two is elastically engaged, connector includes the cylindric connector with spliced eye, the spliced eye
For being arranged with external piece grafting, it is symmetrical arranged on the side wall of connector there are two the circular mounting hole for installing steel ball, is pacified
Dress hole is connected to spliced eye, and the access approaches that mounting hole selects circle to allow for matched steel ball are relatively broad, cost
It is cheap, select circular hole more to have cost advantage than other polygonal holes, also convenience more faster than other holes, replacement are outer for the assembly of circular hole
Steel ball and sleeve are point contacts during fitting, and frictional force is small, noise is small, and precision is high, and long service life is not easily to fall off.
As shown in Figure 3-4, the lower end of connector is provided with spring step, is used to support spring, the work for preventing spring from falling off
First terrace, convex ribs, second step face are disposed with from top to bottom with, sleeve lining, the inner walls of convex ribs and connector
Outer wall matches, and spring installation cavity is formed between convex ribs and spring step, and spring socket is set in spring installation cavity
On the outer wall of connector, spring step necessarily is greater than second step face, if being equal to or less than second step face, second step face
Angle can generate collision with spring and spring step and cause to wear.First terrace forms first to the distance between sleeve top
Adjustment hole, the distance between convex ribs to First terrace formed the second adjustment hole, second step face to sleeve bottom end apart from shape
At limit hole.
Further, the diameter of mounting hole is necessarily less than the diameter of steel ball, otherwise, once sphere more than half stick into mounting hole
It is interior, lead to not pop up, excessive mounting hole results even in steel ball and falls into spliced eye, causes external piece that can not install.Often
When state, the plane extending into where the prominent mounting hole of its arc-shaped outer surface of the steel ball in mounting hole, the arc of the other side of steel ball
The inner wall of face and the second adjustment hole contradicts；The setting of position of mounting hole, the distance and second step of mounting hole to connector top
The lower surface in face is equidistant to circlip upper surface, if mounting hole is too small with a distance from connector upper surface, is replaced external
Sphere is easy to fall off when part.Distance is too big, and external piece is easy to loosen, and influences using effect.The lower end of connector is additionally provided with card
Spring slot, the interior clamping of jump-ring slot are provided with circlip, and the setting of jump-ring slot limits extreme position when replacement external piece, prevents steel ball
It falls off.
Further, when the first adjustment hole slips down to steel ball position, one end of steel ball and the first adjustment hole inner wall point contact,
The other end of steel ball is located in mounting hole but does not protrude spliced eye inner wall.The diameter of first adjustment hole is too small, in replacement external piece
When, the outside extreme position of limitation steel ball can not reserve sufficient space to external piece if steel ball cannot pop up, and will affect outer
The replacement of fitting.The diameter of first adjustment hole is too big, does not constrain steel ball extreme position, when will lead to replacement external piece, steel
Ball falls off.The effect of second adjustment hole be when the quick coupling is in the normal state work to steel ball apply certain power make it is external
Part and connector are fitted close.So also there are certain requirements to size, size is too small, and steel ball can not be installed, and size is too big, steel ball
It is easy to fall off.Convex ribs support steel ball under normality working condition, limit the extreme position of connector；Second step face limits circlip pole
Extreme position；The effect of limit hole facilitates circlip to be fitted into the jump-ring slot in connector.
When quick coupling of the present invention is installed, connection head-tail is first put on into spring, is reloaded into sleeve, then spring is pressed onto
Mounting hole on connector is completely exposed for least limit position, is packed into steel ball, then recovery spring to relaxation state, finally
Circlip is fitted into the jump-ring slot in connector, the installation of quick coupling is completed, it is convenient and efficient.
When external piece is replaced in quick coupling, sleeve drop-down, connector upper end is exposed, compression shape of the steel ball from the first adjustment hole
State enters the second adjusting hole site, and steel ball is displaced outwardly, and empties the inner space of spliced eye, and external piece enters the interior of spliced eye
Portion.Releasing sleeve, under the action of the spring, sleeve are returned to normality operating position.At this point, external force of the steel ball in the second adjustment hole
Radial force is applied to external connection body under effect, steel ball is fitted closely with the groove location on external connection body, to realize consolidating for external piece
It is fixed.
