Abstract

The utility model relates to a connecting piece. Holes are disposed on the end surfaces of the connecting piece; and a circle of perforation grooves are arranged outside the holes on at least one end surface. The connecting piece has the advantages that the appearance is artistic, the installation is quick, a part can be reliably connected with a pipe simultaneously in different directions through the holes and the grooves, the kinds of the pipe connecting piece are reduced, meanwhile, the extended function of the additional connection of the connecting piece is realized, and all the problems are solved.

Description

Link

Technical field

The utility model relates to a kind of link that tube and tube is connected.

Background technique

At present, ways of connecting is common following several between the known tube and tube:

I, by at the flange hole of pipe end face, couple together with the pipe of bolt two or more;

II, be " one " with some profiles, " L ", " T ", " ten ", " Y " shape sheet link couples together pipe;

To manage in twos directly butt joint with transition piece between III, the pipe or multidirectional transition piece couples together pipe;

Directly welding between IV, pipe;

The I kind takes up room greatlyyer in above-mentioned four kinds of pipe Placements, is difficult to realize at crossover location the connection of many pipes; II kind Placement can take the useful space between pipe equally, needs multiple different link to realize that the multitube of crossover location connects, and loses simultaneously in attractive in appearance; III kind Placement transition piece kind is too much, to pipe shape requirement height, diminishes outward appearance simultaneously; IV kind Placement is applicable to metal tube, but product appearance, packing, transportation, installation are all made troubles.

The model utility content

In order to solve the problem that above-mentioned several connection is difficult to overcome, the utility model provides a kind of link.This link is beautiful shape not only, quick for installation, and can realize that a plurality of directions of part all can be connected with the reliable of pipe simultaneously, have reduced the kind of tubular union, be also that simultaneously this link can realize the additional extension function that connects, solved above-mentioned all problems.

In order to address the above problem, the utility model is taked following technological scheme:

A kind of link, porose in the end face processing of link, there is a circle through slot in the outside, hole of at least one end face.

Preferably, described link is cylinder or cone.

Preferably, an end face opening of described cylinder or cone link.

Preferably, it is unlimited fully that described link has an end face.

Preferably, be provided with projection in the groove of described link end face.

Preferably, groove be provided with up and down the symmetry four projectioies.

Preferably, on the external frame seamed edge of described end face groove bull nose is arranged, inwall forms filleted corner.

Preferably, the hole of link end face is square, and is circular or oval.

The beneficial effects of the utility model are: this link is beautiful shape not only, quick for installation, and can utilize hole and groove to realize that a plurality of directions of part all can be connected with the reliable of pipe simultaneously, reduced the kind of tubular union, be also that simultaneously this link can realize the additional extension function that connects, solved above-mentioned all problems.

Embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

A kind of link, its effect mainly is the connection that is used between the tube and tube, can be in furniture, building, displaying exhibition and indoor and outdoor decorations field.

See figures.1.and.2, the link of present embodiment is a cube structure, link above it in the middle of the porose 1-4 of processing, bottom surface opening (perhaps as no end of the Fig. 2), mainly be to make other extension function to use, outer surface (side) is gone up processing groove 1-2 and hole 1-1 around all the other.Each face is all can be as the existing groove in side porose again or porosely do not have groove or have only groove not have the hole as top, and different structure is suitable for different pipe fittings.Hole 1-1 is in the centre, and groove 1-2 is positioned at the outside of hole 1-1, and along the periphery setting of sidewall, groove 1-2 is a groove, and four protruding 1-3 are arranged in the groove, and also for the ease of processing, four protruding 1-3 are symmetrical arranged up and down, generally are located at the neutral position on every limit for attractive in appearance.Certainly, also can establish a projection or do not establish projection.Above-mentionedly except the hole of centre, also can add a plurality of aperture 1-4 at the face that does not have groove.

As Fig. 1, Fig. 2, on groove 1-2 external frame seamed edge, outward appearance fillet 1-6 is arranged, inwall has fillet 1-7.

As Fig. 3, rectangular tube (pipe to be connected) has breach 2-1 on the four sides, bolt 2-3 is connected with iron plate 2-2, iron plate 2-2 is connected with rectangular tube, all be connected firmly, mouth of pipe center position is fixed with bolt 2-3, and bolt 2-3 can be screwed into by the hole 1-5 above this link, be screwed on the bolt 2-3 of pipe from the link bottom opening nut 3-3 that can pack into, swivel nut is tightened can be real compact solid with link and duct ligation.The mouth of pipe to be connected can snap among the groove 1-2 of link, and the breach of pipe cooperates with protruding 1-3 in the link groove, plays position-limiting action.

Among Fig. 4: link 3-2 with the assembling of pipe 3-1 is: the bolt (2-3 among Fig. 3) that at first will manage 3-1 inserts in the hole (1-1 among Fig. 1) of link 3-2, the mouth of pipe of 3-1 is inserted in the groove (1-2 among Fig. 1) of 3-2, breach (2-1 among Fig. 2) cooperates with projection (1-3 among Fig. 1), plays position-limiting action; Be installed on the bolt (2-3 among Fig. 2) of pipe 3-1 with nut 3-3 then, firmly screw solid fastening.If also be attached thereto just like the pipe shown in the 3-1 around the link 3-2, then pressing as above, the order repetitive operation gets final product.The advantage of this connection is that single face or four sides connect mutual noninterference, all can independently install, and increases the flexibility that connects, simultaneously firm and reliable connection; All be hidden in the bottom surface inner chamber of link 3-2 owing to nut 3-3 goes up bolt (2-3 among Fig. 2) with pipe 3-1 elsewhere, make profile succinctly attractive in appearance.

Among Fig. 5: be the extension application example of the utility model link, can form one side, two, three, the difference connection of combination in any on four sides, and can framework infinitely be extended by link.If be increased in the auxiliary extension of link bottom surface 4-1 direction and top 4-2 direction again, then can form the frame structure in space.

The hole of link end face can be square, and is circular or oval, can connect difform pipe fitting.

The foregoing description is the example explanation with the square body, and described link can also be other shapes, as rules and irregularly shaped such as cones, for the ease of producing the preference rule shape in enormous quantities.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
