Primary and foremost purpose of the present utility model is to be to design a kind of linkage structure parts that rise by big clamp ring and reach locking effect that advanced by screw rod.Another purpose of the present utility model is the employing that is to design a kind of described joint, can't influence the linkage structure parts that other assembly passes through.

The utility model is realized by following design: form the locking screw of linkage structure parts, the one end can be fixed in itself on the part of required connection, and its other end then is threaded taper.Another clamp ring of forming the linkage structure parts then is placed on the threaded taper, and both are inserted in the hole on another part of required connection in the lump.When turning locking screw, the drive oing boldly of threaded taper risen by cover clamp ring thereon to combine with the hole that is inserted greatly and tightly and realized purpose of connecting.Establish a leading-in end of forming by curved surface or inclined-plane at the top of locking screw, so that being inserted in of described clamp ring, and place restrictions on coming off of its.In clamp ring, offer a groove, more help clamp ring and be inserted in locking screw, also help the harmomegathus of clamp ring self and effectively realize the design's effect.When locking screw being made hollow, then can therefrom assign other assembly.

Effect of the present utility model is tangible, the part of some elongateds, as the umbrella bar that covers sunshade in seabeach or street corner, and the column bar or the like of desk lamp on the spot, all be one long, all very inconvenient and uneconomic defective of the processing of integrated product, packing, transportation, storage.But when it adopted screw type lock-on connection described in the utility model, the link that it can be changed into by a plurality of short types was formed by connecting, and combines closely between connecting body, and can not rock or come off because of there not being the gap therebetween, can guarantee fully to use.Again because the utility model when using, its loading and unloading all is a thing extremely easily, does not need any special instrument and technology, but the user fully being made by manufacturers or users use.And during production and selling, then owing to adopt the link of short type, then its processing, packing, transportation, storage are all extremely convenient, will bring huge economic benefit and convenient material benefit.Through hole in the middle of the described lock-on connection then can be used for interting other assembly, and as the column bar of desk lamp on the spot, the through hole in the middle of it can be used for interting electric wire, and the utility model can be avoided the common deficiency that causes electric wire to reverse because of turning fully.The design can be used for the connection between the pipe fitting, also can be used for the connection that pipe fitting stands on the plane, also can expand to be used for being connected between plane and plane member.In a word, behind employing the utility model, can realize the described expected effect of this specification.

Below in conjunction with accompanying drawing embodiment of the present utility model is described, thereby make CONSTRUCTED SPECIFICATION of the present utility model, characteristics, purpose and advantage clearer and more definite.

Fig. 1 is the utility model embodiment's a structural drawing.

Fig. 2 is the application schematic representation of present embodiment.

Among the figure: 1-locking screw, 2-clamp ring, 3-leading-in end, 4-flange, 5-groove 6-locking section 7-screw thread 8-fixed end 9-link 10-link 11-central through bore 12-interspersed assembly 13-approaching face 14-surplus glue groove.

The utility model embodiment's structure now is described in conjunction with the accompanying drawings:

Shown in accompanying

drawing

1,2, the described a kind of screw type lock-on connection of present embodiment comprises that locking screw, clamp ring form.Described locking screw 1 is made of fixed end 8,

locking section

6,3 three sections institutes of leading-in end by its effect.Wherein fixed end 8, can with link 9 on one be connected hole and be complementary and fix, means of fixation commonly used can be compression fit, or gummed.6 of locking sections are the conical screw of a band single head or multiple thread 7, and multiple-threaded employing can be shortened helical pitch, thereby can reduce the angle that turns locking screw 1 in use.The top of leading-in end 3 has one by the approaching face 13 that curved surface or inclined-plane constituted, so that described clamp ring 2 is inserted on the locking screw 1.The bottom of leading-in end 3 then joins with locking section 6, and forming a circle flange 4, clamp ring 2 slippages that can be used for preventing to be inserted in are in locking screw 1, particularly when dismounting, very easily slippage under the effect that clamp ring 2 is obstructed in its outer ring, and fall among the connection hole of another link 10.Described clamp ring 2 is to be made by nonrigid material, has harmomegathus under external force, its profile then with another link 10 on the hole that is connected match.When it is placed on the locking section 6, and when locking screw 1 is screwed into, clamp ring 2 inner ring pressurizeds under the effect of taper and by spreading, its outer surface then more is close to the hole wall that connects hole on the associated link 10, thereby make two

links

9,10 by joint that present embodiment provided, closely link into an integrated entity, reach the design's predetermined purpose; When becoming flexible locking screw 1, then same because the effect of taper, the pressure of the suffered locking screw 1 of clamp ring 2 inner rings disappears, clamp ring 2 is shunk and is restored, this moment clamp ring 2 outer rings with link 10 on the pressure that is connected between the hole wall weaken simultaneously, until disappearance, the effect of described lock-on connection forfeiture, two links are separable again.Present embodiment is the connection between two pipe fittings as shown in drawings.The utility model still can be used for pipe fitting and stands on interplanar connection, is about to described lock-on connection and is positioned on the structural member of plane by its fixed end 8, again the cylinder structure spare of required connection is inserted in lock-on connection and gets final product.By identical principle, the utility model also can be expanded and be used for being connected between plane and plane member.

For guaranteeing that present embodiment can realize the effect of expecting better, a groove 5 can be set in described clamp ring 2.At this moment, the strip off clamp ring 2 a little, can easily it be inserted in locking screw 1.When tightening locking screw 1, then groove 5 can allow clamp ring 2 be easy to spreading and the effect that realizes locking.

In order between two links, to intert other assembly in case of necessity, as the column bar of desk lamp on the spot, just may need interspersed electric wire in the middle of it, can on described locking screw 1, central through bore 11 be set, allow required interspersed assembly 12, for example described electric wire passes through.Electric wire by the present embodiment central through bore and so on object, the angle of reversing because of link is required is very little, therefore can avoid fully turning common defective such as cause that electric wire reverses because of link.

In order to ensure the reliability that is connected between locking screw 1 and link, many surplus glue grooves 14 are set on the surface of fixed end 8, for between described locking screw 1 and link when glueing joint, unnecessary glue can flow in the surplus glue groove 14, the glue that had both guaranteed q.s is guaranteed bonding quality, can avoid the outflow of surplus glue again and influence its appearance quality.Described surplus glue groove 14 can also can be made straight shape groove along generatrix direction, or tilt to form thread-shaped with bus by making annular shown in the accompanying
