Abstract
The invention relates to a pipeline connecting piece, and in particular relates to a pipe fitting connector for a thin-wall hole. The pipe fitting connector comprises a connecting rod and a compression nut which is in threaded connection with the connecting rod. The pipe fitting connector is characterized in that one end of the connecting rod is fixedly connected with a tapered expansion body, and the other end of the connecting rod is provided with external screw threads; an elastic body is sleeved on the connecting rod between the tapered expansion body and the compression nut; and the elastic body is of a circular tube type. By utilizing the connecting body, a pipe fitting can be convenient to connect from the front surface on the thin wall, the strucuture is simple, and the pipe fitting connector is convenient to use; and the operation is only carried out at the outer side of the thin wall as required, and the difficulty brought about from the operation of two sides can be avoided; and after installation, the tightness property of the thin wall and the pipe fitting is good, and the pipe fitting connector is especially suitable for the situations which require seal, such as water tanks and the like.
Description
Technical field
The present invention relates to a kind of pipe joint, especially a kind of pipe fitting connecting body that is used on the thin-walled hole.
Background technique
Pipe laying link on thin-walled pressure vessels such as solar water heater water tank can adopt and on thin-walled, punch earlier, and the method with bolt is fixed on link on the thin-walled hole then.But this installation method must be in the operation of the two sides of hole wall, and link is positioned at the outside in thin-walled hole, and nut is installed in the inboard in thin-walled hole.But for containers such as the solar water heater water tank that has been shaped, bottle, buckets, owing to can't hand be put in the internal tank operation, also just can't be at the installed inside nut in thin-walled hole.For this container, the outside welding that is employed in the thin-walled hole usually adds the method for high nut, and the nut in the utilization welding is connector member again, and this method not only wastes time and energy, and is also inapplicable for working of plastics and the ultra-thin thin-walled pressure vessel that can't weld.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to use, quick installation and be used for the pipe fitting connecting body on the thin-walled hole.
The technological scheme that the present invention is adopted for the technical solution problem is:
The pipe fitting connecting body that is used on the thin-walled hole of the present invention comprises connecting rod, through being threaded in the gland nut on the connecting rod; It is characterized in that: an end of said connecting rod is fixedly connected the taper expander; The other end of connecting rod has outside thread; On the connecting rod between taper expander and the gland nut, be set with elastomer, said elastomer is the pipe shape.
Have annular boss at gland nut towards an elastomeric side, the internal diameter of said annular boss, external diameter and elastomer internal diameter, the external diameter under the non-stress state is suitable.
On connecting rod, be set with stiffening ring, the internal diameter of said stiffening ring is greater than the external diameter of elastomer under the non-stress state, and the external diameter of stiffening ring is less than the external diameter of gland nut.
Above-mentioned connecting rod is the tubulose of hollow.
Adopt after the technique scheme, utilize this connecting body connection pipe fitting on thin-walled easily, simple in structure, easy to use; And only need be in the operation of the outside of thin-walled, the difficulty of avoiding the two sides operation to bring; The good seal performance of back thin-walled and pipe fitting is installed, is particularly useful for the occasion of needs sealings such as water tank.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the schematic representation of Fig. 1 embodiment user mode.
Embodiment
As shown in Figure 1, the pipe fitting connecting body that is used on the thin-walled hole of the present invention comprises connecting rod 3, through being threaded in the gland nut 2 on the connecting rod 3.Wherein, according to design demand, connecting rod 3 can be the tubulose of hollow, also can be solid shaft-like, and present embodiment is because need be communicated with the interior outside in thin-walled hole, so what adopt is the structure of the tubulose of hollow.One end of connecting rod 3 is fixedly connected the taper expander, and the helical thread portion on the upper end of this taper expander and the connecting rod 3 seamlessly transits, and expand gradually the lower end of taper expander.The other end of connecting rod 3 has outside thread, on the connecting rod 3 between taper expander and the gland nut 2, is set with elastomer 4, and said elastomer 4 is the pipe shape.Elastomer 4 can adopt the stronger material manufacture of elasticity such as rubber, plastics.Certainly, also can adopt copper, aluminium or elasticity, alloy material that ductility is good.
Have annular boss at gland nut 2 towards a side of elastomer 4; The internal diameter of said annular boss, external diameter and elastomer 4 internal diameter, the external diameter under the non-stress state is suitable; Promptly the diameter of this annular boss and wall thickness all equate with elastomer 4, perhaps in the scope that tolerance fit allows.The effect of this annular boss is better to compress elastomer 4, and can not receive the interference of object on every side.
In addition, on connecting rod 3, be set with stiffening ring 5, the internal diameter of said stiffening ring 5 is greater than the external diameter of elastomer 4 under the non-stress state, and the external diameter of stiffening ring 5 is less than the external diameter of gland nut 2.The effect of stiffening ring 5 is the steps on protecting on the thin-walled hole; Because be used for the hole on the working of plasticss such as water tank; Usually in processing, can around the hole, increase the step of a convexity; Be used for strengthening the intensity of hole wall, stiffening ring 5 is enclosed within the outside of this step, can protect step can not be out of shape because of the extruding of gland nut 2.
As shown in Figure 2; In the time of actual the use, the maximum outside diameter outline of the taper expander on the connecting rod 3 makes it can just put the thin-walled hole into and gets final product less than the diameter in the thin-walled hole on the workpiece 1; But the difference of the maximum outside diameter of the diameter in thin-walled hole and taper expander can not be greater than the wall thickness of elastomer 4.Internal diameter and the external diameter of connecting rod 3 of elastomer 4 under the non-stress state is complementary, and the external diameter of elastomer 4 under the non-stress state is not more than the maximum outside diameter of taper expander at least, preferably equals the maximum outside diameter of taper expander.Stiffening ring 5 is enclosed within on the step in thin-walled hole, the connecting rod 3 that will have elastomer 4 is put in the thin-walled hole, after elastomer 4 gets in the thin-walled hole fully; Rotatably compress nut 2, promote elastomer 4 to lower slider, because of elastomer 4 has certain elasticity through annular boss; Under the squeezing action of gland nut 2; Elastomer 4 can slide on the taper expander, this moment the taper expander maximum outside diameter add elastomer 4 wall thickness greater than the diameter in thin-walled hole, it can not be come off from the thin-walled hole.Continuing to rotatably compress nut 2 can be fixing with connecting rod 3.
After connecting rod 3 was fixed, the unnecessary helical thread portion in gland nut 2 upper ends can be used for connecting external pipeline.
