Abstract

The utility model provides a plastic pipe universally- used decorative cap, belonging to the technical field of mechanism. The utility model solves the problem of unstable fixation of the decorative cap in the prior art. The plastic pipe universally- used decorative cap which is used at the joint of the plastic pipes includes a decorative cap head and a cap shed which is connected with the decorative cap head, wherein, one end of the decorative cap head is connected fixedly with the cap shed along the circumference; the decorative cap is trumpet- shaped, with the bigger end connected with the cap shed; the inner wall of the decorative cap and the cap shed is connected fixedly with a plurality of blades, which are arranged axially along the annular decorative cap head and the cap shed. While a plastic pipe is connected with a plastic pipe fitting or plastic valve, the blades which are connected fixedly on the inner wall of the decorative cap are extruded and deformed under the effect of the external force, and then combined close with the connecting part of the plastic pipe fitting or the plastic valve, in order to make the decorative cap be fixed firmly at the connecting part. Due to different bore diameters of the decorative cap heads and cap sheds, the plastic pipe can be used for the connection between plastic pipe fittings and plastic valves of different specifications, so the applicability is wide.

Description

The general trim of plastic tube

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of trim, the general trim of particularly a kind of plastic tube.

Background technique

The joint of the plastic tube that the device by having electric heating structure such as electric heating wire links together to needs carries out heating and melting to be realized connecting, be that plastic tube is fixedly connected on a kind of usual way on plastic pipe or the Plastic valve, with the cooling at welding position, what plastic tube was just firm has linked together with plastic pipe or Plastic valve after welding.

Though above-mentioned Placement is simple to operate, being connected after the welding between plastic tube and plastic pipe or the Plastic valve is also comparatively tight, but the process of welding but can can't return to original state after the cooling with the joint fusing of plastic tube and plastic pipe or Plastic valve, causes joint not attractive in appearance.For this reason, people have designed a kind of trim of plastic tube, are enclosed within the joint between plastic tube and plastic pipe or the Plastic valve, and inaesthetic joint is covered.

But as can be seen, above-mentioned trim is enclosed within the joint again after the plastic tube connection is finished, there is not effective means of fixation between trim and the plastic tube, only rely on the plastic tube surface to realize fixing with tight contact the between the trim inner ring, time one, trim of a specified duration broke away from the joint, made outside joint is exposed to.

Summary of the invention

The purpose of this utility model is the existing the problems referred to above of trim at existing plastic tube joint, and has proposed a kind of in the joint fixation and can be applicable to the general trim of plastic tube that the plastic tube of different size connects.

The purpose of this utility model can realize by following technical proposal: the general trim of plastic tube, the joint that is used for plastic pipe, this trim comprises trim headkerchief and the lid skirt that links to each other with the trim headkerchief, one end of described trim headkerchief is fixed together along circumference with the lid skirt, it is characterized in that, described trim headkerchief is horn-like, its big end is connected with the lid skirt, be fixed with several blades on the inwall of trim headkerchief or lid skirt, described blade axially is provided with along annular trim headkerchief and lid skirt.

The trim headkerchief is enclosed within on the plastic tube after being connected with the lid skirt, and plastic tube contacts heat fused afterwards with the joint of plastic pipe or Plastic valve, just fixed firmly after the cooling.At this moment, promoting trim makes trim slide on the joint of plastic tube along plastic tube, cooled joint is covered in, and the blade extrusion-deformation under the effect of external force on trim headkerchief or the lid skirt inwall makes fixation between trim and plastic pipe or the Plastic valve.

In the general trim of above-mentioned plastic tube, described lid skirt is cylindric.Lid skirt cylindraceous can hide the joint preferably.

Another kind of situation, in the general trim of above-mentioned plastic tube, described lid skirt is horn-like, and its small end is connected along circumference with the trim headkerchief.The shape of lid skirt also can be horn-like, forms the tubaeform of an integral body with the trim headkerchief.

In the general trim of above-mentioned plastic tube, described blade is connected with trim headkerchief and lid skirt simultaneously.Blade is connected in the joint of trim headkerchief and lid skirt, and two ends are connected with trim headkerchief and lid skirt respectively simultaneously.

In the general trim of above-mentioned plastic tube, the quantity of described blade is six to ten, evenly is arranged on the inwall of trim headkerchief or lid skirt.The quantity of blade be six to ten be facts have proved more rational.

In the general trim of above-mentioned plastic tube, described blade is made by plastic materials.The blade that plastic materials is made forms easily deformation under the effect of external force, be convenient to trim is fixed on the joint of plastic pipe or Plastic valve, can restore to the original state again after taking off trim.

Compared with prior art, the general trim of this plastic tube is fixed with several blades on the inwall of trim, plastic tube is with when plastic pipe or Plastic valve are connected, blade extrusion-deformation under the effect of external force, combine closely with the joint of plastic pipe or Plastic valve, make the fixation of trim in the joint.The trim headkerchief is different with the aperture of lid skirt, plastic tube can be used for the plastic pipe of different size or Plastic valve between be connected, applicability is wide.In addition, the general trim of the plastic tube of different colours is socketed in and can be convenient to offer an explanation the hot and cold water pipeline on the different plastic tubes.

Embodiment

Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.

As shown in Figure 1, the general trim of this plastic tube is used for the joint of plastic pipe 6, comprises trim headkerchief 1 and the lid skirt 2 that links to each other with trim headkerchief 1, and lid skirt 2 is cylindric, and trim headkerchief 1 is horn-like, its big end with cover skirt 2 and be connected together along circumference.

As Fig. 2 and Fig. 3 and shown in Figure 4, axially be provided with on the inwall of trim headkerchief 1 and lid skirt 2 on the inwall that 3, eight blades 3 of eight plastic blades are evenly distributed on trim headkerchief 1 and lid skirt 2.

Trim headkerchief 1 is enclosed within on the plastic tube 5 after being connected with lid skirt 2, and plastic tube 5 contacts heat fused afterwards with the joint 4 of pipe fitting 6, just fixed firmly after the cooling.At this moment, promoting trim makes trim slide on the joint 4 of plastic tube 5 along plastic tube 5, cooled joint 4 is covered in, and blade 3 extrusion-deformation under the effect of external force on trim headkerchief 1 or lid skirt 2 inwalls makes fixation between trim and plastic pipe or the Plastic valve.

Another kind of situation, lid skirt 2 is horn-like, and its small end and trim headkerchief 1 are connected along circumference, make whole trim be the tubaeform of one.
