Description

A kind of fast assembling-disassembling connector

Technical field

The utility model relates to connector, particularly a kind of fast assembling-disassembling connector.

Background technology

When people will be with pet (as dog) when trotting out, need be fixed on the necklace with a pull rope, thus the scope of activities of restriction pet, to avoid the unnecessary trouble of pet and other people or deposits yields.And when go back home or enter safety or sealing local time, pet owners often needs pull rope and necklace are separated because they do not wish pet is tied down separately, do not wish yet pet in tow rope scoot about.Thus, pet owners can often be made the action of demolition, installation pull rope.Hook commonly used is to promote pin with spring, will be hung object and be limited in the annulus of a sealing.Such device makes people all will pull open switch with hand when dismounting, aims at hook simultaneously.This is for active, a moving pet of not stopping transport, and is once success not too easily, and is inconvenient more as the people of finger disappearance or blind person to some physical disabilities more even.

The utility model content

Technical problem to be solved in the utility model provides a kind of fast assembling-disassembling connector, and it can connect or take apart two parts laborsaving, rapidly.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of fast assembling-disassembling connector, constitute by matrix and insert two parts, described matrix has housing, the housing internal clearance is equipped with a ball seat, and the part of ball seat is exposed to outside the housing, has cylindrical hole in the ball seat, described cylindrical hole lower end is connected with a magnet, and the cylindrical hole surface also is provided with a circle trapezoidal groove; Insert has sheathed successively jackshaft, overcoat and short sliding sleeve, short sliding sleeve is positioned at the top of overcoat, the jackshaft bottom has a circumferential arc groove, the overcoat wall that described arc groove is relative is provided with several through holes, the space content that described through hole and arc groove form is equipped with and the isodiametric steel ball of through hole, through hole outermost diameter is slightly smaller than the diameter of steel ball, middle part at described jackshaft and overcoat is equipped with pin-and-hole, be equipped with a pin in the pin-and-hole, and the pin-and-hole that is positioned on the jackshaft is a Long Circle, at jackshaft, the top of overcoat and short sliding sleeve is equipped with pin-and-hole, be equipped with a pin in the pin-and-hole, and being positioned at the outer pin-and-hole that puts is Long Circle, on described jackshaft, also be arranged with a spring, spring between two pins, jackshaft be shorter in length than overcoat, and the distance of jackshaft lower surface and overcoat lower surface is greater than the width of arc groove on the jackshaft, and the stroke of two pins is not less than the distance of jackshaft lower surface and overcoat lower surface.

The utility model can also have following structural design: described matrix lower end is provided with capping; Described outer set upper side is connected with a pull head.

The beneficial effect that the present invention can produce is: this utility model is used to connect Pet neck ring in pull rope, and better intensity will be provided, and can make owner face active moving pet to fasten quickly and easily or unclamp them.Be very helpful for eye and the handicapped personage of hand especially,, also do not need with the hands to carry out difficult aligning because it does not need to stir some switch with very big strength.

Cutaway view when Fig. 3 is the connection of the utility model embodiment connector.

Embodiment

This embodiment is used in the fast assembling-disassembling between Pet neck ring and the lead.

Consult Fig. 1, Fig. 2, the utility model embodiment quick detach connector, comprise matrix and insert, matrix is made up of housing 1, capping 2, capel 3, ball seat 4 and magnet 5, be equipped with ball seat 4 in the housing 1, ball seat 4 is stuck in the housing 1 by a capel 3 and can freely rotates in housing 1, offers a cylindrical hole in the ball seat 4, the affixed magnet 5 in through hole lower end, capping 2 is closed in ball seat 4 in the matrix from the matrix lower end.Go back in the through hole along circumferentially offering trapezoidal groove 15.

Insert comprises jackshaft 6, overcoat 7, short sliding sleeve 8 and pull head 16, jackshaft 6 outer sheathed successively overcoat 7 and short sliding sleeves 8, and short sliding sleeve 8 is positioned at the top of overcoat 7.Jackshaft 6 bottoms have a circumferential arc groove, the overcoat wall that arc groove is relative is provided with 4 through holes, the space content that described through hole and arc groove form is equipped with and the isodiametric steel ball 10 of through hole, the through hole outermost makes its diameter be slightly smaller than the diameter of steel ball 10 by embossing or other means, in order to avoid steel ball 10 landings are outside through hole.Middle part at described jackshaft 6 and overcoat 7 is equipped with pin-and-hole, is equipped with a hair(-)pin 12 in the pin-and-hole, and the pin-and-hole 11 that is positioned on the jackshaft 6 is Long Circle, and the radius of 11 liang of round ends of this oval pin-and-hole is identical with the radius of hair(-)pin 12, so that motion stabilization.Top at jackshaft 6, overcoat 7 and short sliding sleeve 8 is equipped with pin-and-hole, is equipped with a thick pin 13 in the pin-and-hole, and is positioned at the outer pin-and-hole that puts 14 and is Long Circle, and the radius of 14 liang of round ends of this oval pin-and-hole is identical with the radius of slightly selling 13.Two oval pin-and-holes 11 and 14 long back gauge equate.Also be arranged with a spring 17 on described jackshaft 6, spring is between thick pin 13 and hair(-)pin 12.Jackshaft 6 be shorter in length than overcoat, and the distance of jackshaft 6 lower surfaces and overcoat lower surface is greater than the width of arc groove on the jackshaft, and the long back gauge of two oval pin-and-holes equates with the distance of jackshaft lower surface with the overcoat lower surface, so that the connector folding is more steady.Connect pull heads 16 on the top of overcoat 7 by an extension pull head 9 that is spirally connected on it, pull head 16 can be used to connect pull rope.

Consult Fig. 3, during use, matrix is connected the necklace of pet, when owner connects pull rope and necklace, insert need only be inserted in the cylindrical hole 15 of ball seat 4.At this moment, under the attraction of powerful magnet 5, jackshaft 6, slightly sell 12 and short sliding sleeve 8 pressuring springs 17 move downward, the through hole dislocation position of jackshaft 6 bottom arc grooves and overcoat 7, thereby steel ball 10 is radially outwards ejected, and overhead kick is in the trapezoidal groove of ball seat 4 inner via holes, and maintenance.This moment, matrix and insert blocked, and can not separate.Because the radial thrust of steel ball 10 promotes the groove that steel ball 10 blocks ball seat 4, thus can not be opened axially bearing very big pulling force, fool proof.When owner opens two parts, need only gently carry sliding sleeve 7, drive thick pin 13 and jackshaft 6 and move upward, make the bottom arc groove of jackshaft 6 aim at the lead to the hole site of overcoat 7 once more, steel ball 10 can inwardly shrink in radial direction, just can extract smoothly between insertion, gets back to initial state.

This utility model is used to connect Pet neck ring in pull rope, and better intensity will be provided, and can make owner face active moving pet to fasten quickly and easily or unclamp them.Be very helpful for eye and the handicapped personage of hand especially,, also do not need with the hands to carry out difficult aligning because it does not need to stir some switch with very big strength.
