Description
Technical field
The utility model relates to a kind of pipe connecting structure, relates in particular to a kind of end inside of a pipe that is positioned so that a kind of structure of this pipe and another object strong fix.
Background technique
For rack miscellaneous, the structure of being formed with hollow straight tube not only has enough support strengths, saves on the material, and all can effectively save occupation space after dismounting or before the assembling, conveniently to store and to carry.Therefore, present employed rack is assembled with iron pipe, Stainless Steel Tube or Al-alloy pipe.
As shown in Figure 5, be a kind of pipe connecting structure A commonly used, wherein, serving as one a group of straight tube B and transverse tube C that is T type configuration in order to connect rack, mainly is earlier behind the disk A1 with punch ram one bowl-type, and a nut A2 is welded on the disk A1, again disk A1 is welded on the end inside of transverse tube C in the spot welding mode, after passing straight tube B, be screwed together on the nut A2, to reach the purpose that connects the location at a screw A3.
But in the position fixing process of aforementioned tube linkage structure A, must weld, therefore, not only have artificial error easily, cause quality to be difficult to control, and can increase manufacture cost, and reduce competitive ability with manual type.
The model utility content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art a kind of processing and assembly program and cost-effective pipe connecting structure simplified is provided.
For solving above technical problem, the utility model adopts following technological scheme: a kind of pipe connecting structure, and it is used to connect a pipe and an object, and it comprises,
One sleeve pipe, it is used to be positioned in the pipe, and the periphery of described sleeve pipe offers a vertical breach, and this sleeve pipe has the inner conical tube wall;
One extrusion, it is arranged at the inside of sleeve pipe coaxially, and described extrusion has the taper outer tube wall that the inner conical tube wall with described sleeve pipe is complementary, and axially offers screw along described extrusion; And
The screw that one screw rod, one end are used to pass behind the object with described extrusion is screwed, and when the rotating screw bolt the other end, described sleeve pipe expands outwardly at the mobile lower stress of extrusion, thereby offsets with an end inboard of pipe.
Further, the another side of described sleeve pipe is provided with block piece, by block piece is set, can avoid extrusion and trustship to break away from, thereby can be effectively with the extrusion location, to quicken built-up time.
Because the enforcement of above technological scheme, the utility model compared with prior art has following advantage: the utility model pipe connecting structure, in use, by mobile extrusion, make sleeve pipe expand outwardly, thereby sleeve pipe pushes against the inner end at pipe, guaranteed the strong fix of pipe and object, assembling is simple, and is easy to process, save cost, have bigger practicability.

Embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment is elaborated:
Pipe connecting structure as shown in Figure 1, it comprises a sleeve pipe 2, an extrusion 3 and a screw rod 4.
Wherein, sleeve pipe 2 is short pipe shape, and the periphery of this sleeve pipe 2 is provided with a vertical breach 21, thereby makes that the cross section of sleeve pipe 2 is c-shaped.Sleeve pipe 2 comprises that a leading flank 22 and is in reverse to the trailing flank 23 of this leading flank 22, the leading flank 22 of this sleeve pipe 2 is provided with a plurality of axial grooves 24, and in the present embodiment, groove 24 is a rectangular, certainly, described groove 24 can be circular or other geometrical shape.The leading flank 22 of this sleeve pipe 2 is formed with a roundlet 25 coaxial with this sleeve pipe 2, the trailing flank 23 of sleeve pipe 2 is formed with a great circle 26 coaxial with this sleeve pipe 2, extend great circle 26, inner conical tube wall 27. whiles of roundlet 25 to form this sleeve pipe 2, the trailing flank 23 of this sleeve pipe 2 is provided with two projections that extend towards the axle center backward and respectively, these two projections are symmetrical in the axle center of sleeve pipe 2, and two projections are as block piece 28.
Described extrusion 3 is one to have the cylinder of taper outer tube wall 31, and this extrusion 3 is placed among the above-mentioned sleeve pipe 2, and the inner conical tube wall 27 of the taper outer tube wall 31 of this extrusion 3 and sleeve pipe 2 is complementary.In addition, this extrusion 3 is provided with an axial screw 32, in the specific implementation, described extrusion 3 also can comprise a conical pipe 33 and a nut 34, and this nut be positioned coaxially in the conical pipe 33 as shown in Figure 2, can form an axial screw 32 equally, screw togather for an end of screw rod 4.
As shown in Figure 3, this extrusion 3 is pressed into sleeve pipe 2 inside forward by the trailing flank 23 of sleeve pipe 2, and stopping with location extrusion 3 by block piece 28.When the user with two ends of a needle-nose pliers respectively in two grooves 24 of the leading flank 22 of threading 2 time, but the application of force is dwindled the external diameter of sleeve pipe 2 and is inserted in the end inside of pipe 5 to make things convenient for sleeve pipe 2.After an end of screw rod 4 passes an object 6, can enter by the front end of extrusion 3, screw togather with screw 32 with extrusion 3.During enforcement, this object 6 is a pipe fitting, also can be a flat board.As shown in Figure 4, when the user uses the other end of instrument rotating screw bolt 4, by the relativity of screw rod 4 with the screw 32 of extrusion 3, extrusion 3 is moved forward, the inner conical tube wall 27 of the outer tube wall of taper simultaneously 31 pushing sleeve pipes 2, thus make the expansion of sleeve pipe 2 radially outwards, and after the external diameter of sleeve pipe 2 enlarges, outer tube wall compresses the inner tubal wall of pipe 5, thereby makes this object 6 firmly be connected an end of pipe 5.
The utility model pipe connecting structure has following advantage:
1, the utility model not only can make a pipe and an object strong fix, and can effectively reduce and simplify processing and assembly program, to save cost;
2, the utility model can be positioned extrusion the inside of sleeve pipe, therefore, can effectively avoid extrusion and sleeve pipe to break away from when dismounting, to quicken built-up time.
In sum, the utility model pipe connecting structure can not only guarantee to make a pipe and an object strong fix, and can effectively save processing cost, has bigger practicability.
The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to spirit of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model.
