Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses antibiotic type PVC feedwater tubular product, combine figure 1 and figure 2 to show, including PVC pipe body 1, one end outer wall an organic whole at PVC pipe body 1 is provided with an annular portion 2, annular portion 2 is a ring, annular portion 2 and the coaxial setting of PVC pipe body 1, and an axial side of annular portion 2 deviates from PVC pipe body 1 one side and extends, annular portion 2 has partly to surpass the tip of PVC pipe body 1 on the axial direction promptly, annular portion 2 exceeds the inner wall of this part of PVC pipe body 1 tip in the axial is the loudspeaker form, this part's inner wall one end internal diameter is big promptly, the other end internal diameter is little, the one end that annular portion 2 deviates from PVC pipe body 1 is the great one end of internal diameter, when connecting two PVC pipes, need insert the one end of PVC pipe in annular portion 2 so that two PVC pipes dock, this setting makes PVC pipe insert more convenient.

An annular groove 15 arranged along the circumferential direction of the PVC pipe body 1 is arranged on the end wall of one end of the PVC pipe body 1, which is wrapped by the annular part 2, a sealing ring 14 is embedded in the annular groove 15, the sealing ring 14 is a rubber ring, is partially embedded in the annular groove 15, and is partially positioned outside the annular groove 15, and in addition, the sealing ring 14 is also bonded and fixed in the annular groove 15 through glue; when two PVC pipes are connected, the end parts of the PVC pipes are inserted into the annular part 2, so that the two PVC pipes are butted, and the sealing ring 14 is used for sealing the two PVC pipes.

In order to keep the two PVC pipes butted and tightly abutted after being butted, other structures are arranged on the annular part 2 to prevent the two butted PVC pipes from being separated from each other; the structure comprises elastic clamping strips 3 integrally arranged on one side of an annular part 2, which is far away from the axial direction of a PVC pipe body 1, wherein the elastic clamping strips 3 are provided with a plurality of elastic clamping strips which are arranged at intervals along the circumferential direction of the annular part 2, and a tightening mechanism 4 is connected on each elastic clamping strip 3 so as to enable each elastic clamping strip 3 to be folded towards the center, namely, each elastic clamping strip 3 can be controlled to be drawn towards the extension line of the axis of the annular part 2 through the tightening mechanism 4; when two PVC pipes are connected, after the end part of one PVC pipe is inserted into the annular part 2 and is in butt joint with the other PVC pipe, the elastic clamping strips 3 are controlled to be folded through the tightening mechanism 4, so that the elastic clamping strips 3 are forced to be pressed and attached to the outer wall of the PVC pipe, and the two PVC pipes are prevented from being separated from the mutual butt joint through the friction force between the elastic clamping strips 3 and the PVC pipes.

In this embodiment, tightening mechanism 4 includes strap 5 that passes each elasticity and presss from both sides tight strip 3 in proper order, strap 5 is the plastic band and encloses into an open-ended annular, and be provided with connector 6 at strap 5's both ends an organic whole, connector 6 is also the plastics material, there is the interval between two connectors 6, and all be provided with the perforation that supplies the bolt to pass on two connectors 6, connecting bolt 7 of connecting two connectors 6 passes and threaded connection has fixation nut 8 from the perforation, fixation nut 8 can be ordinary hexagon nut, also can be butterfly nut, through screwing fixation nut 8 in order to reduce the distance between two connectors 6, make the annular that strap 5 encloses littleer, thereby spacing each elasticity presss from both sides tight strip 3 and draws in into littleer circle, thereby play the effect that each elasticity of control presss from both sides tight strip 3 and draws in. In fact, the tightening mechanism 4 may also be a component that can be tightened directly, such as a buckle belt, or even a rope that is tightened directly.

When the elastic clamping strip 3 is limited to be folded, the fixing bolt needs to be rotated, so that the fixing nut 8 is screwed deeper on the connecting bolt 7 to reduce the distance between the two connecting heads 6, in order to prevent the connecting bolt 7 from rotating along with the fixing nut 8 when the fixing nut 8 is rotated to obstruct the screwing of the fixing nut 8, a polygonal embedding hole 9 matched with a nut of the connecting bolt 7 is specially arranged on one of the connecting heads 6, the nut of the connecting bolt 7 is hexagonal, the shape of the polygonal embedding hole 9 is also set to be hexagonal according with the size, when the connecting bolt is connected, the hexagonal nut of the connecting bolt 7 can be embedded in the polygonal embedding hole 9 to limit the rotation of the connecting bolt 7, and therefore the fixing nut 8 can be screwed on the connecting bolt 7 more easily.

In order to improve the friction force between the elastic clamping strips 3 and the PVC pipe, a square friction pad 10 is further arranged and fixed on one surface of each elastic clamping strip 3 facing to the axis extension line of the annular part 2, the friction pad 10 is generally a rubber pad, a square caulking groove 11 is further arranged on each elastic clamping strip 3, the friction pad 10 is partially embedded in the caulking groove 11 and partially protrudes out of the surface of each elastic clamping strip 3, and the strap 5 synchronously penetrates through the caulking groove 11 and the friction pad 10 when penetrating through the elastic clamping strips 3, so that the strap 5 can fix the friction pad 10 and prevent the friction pad 10 from falling off.

Still be provided with draw-in groove 13 on the elasticity presss from both sides tight strip 3, the outer wall an organic whole that PVC pipe body 1 deviates from 2 one ends of annular part is provided with annular protrusion 12, when connecting two the same PVC pipes, annular protrusion 12 on another PVC pipe can be blocked to draw-in groove 13 on the elasticity presss from both sides tight strip 3 to make the connection between two PVC pipes more firm. The arrangement is only for the situation that the annular bulge 12 is arranged on the PVC pipe to be connected, and if the annular bulge 12 is not arranged on the PVC pipe to be connected, the PVC pipe to be connected is firmly connected only by the friction force provided by the elastic clamping strip 3 and the friction pad 10.

Two PVC pipe butt joint installation processes: the one end that does not set up annular portion 2 of PVC pipe earlier passes the annular that the strap 5 encloses and inserts in the annular portion 2 on another PVC pipe, and make two PVC pipe butt joints support tightly, the sealing washer 14 of PVC pipe tip seals up with the gap when butting two PVC pipes this moment, then rotate fixation nut 8, can rotate fixation nut 8 with the spanner, it is simple little, can use one hand to use power to press together two connectors 6 and reuse the other hand to rotate fixation nut 8, make the interval between two connectors 6 compelled to shorten, make strap 5 shrink into littleer ring, make each elasticity press from both sides tight strip 3 and draw in, then friction pad 10 on the elasticity clamp strip 3 is compressed tightly on the PVC pipe, until fixation nut 8 can't continue to screw on connecting bolt 7, can loosen two PVC pipes this moment, two PVC pipes keep sealed butt joints. When the PVC pipe to be connected is correspondingly provided with the annular bulge 12, the annular bulge 12 is required to be clamped in the clamping groove 13 on the elastic clamping strip 3.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
