Abstract
The utility model discloses a pipe joint connected by utilizing ultrasonic welding, which comprises a pipe body and a pipe joint. A straight-ridge convex ring is arranged at the front part of the pipe body, an inner step ridge adapted to the shape of the straight-ridge convex ring is arranged on the inner wall of the pipe joint, and the front end surface of the straight-ridge convex ring is in welded connection with the abutting end surface of the inner step ridge. A lengthened pipe orifice is arranged at the front end of the straight-ridge convex ring, an annular insertion slot is arranged at the bottom of the pipe joint, and the lengthened pipe orifice is inserted into the annular insertion slot. The pipe joint disclosed by the utility model is designed by adopting the straight-ridge convex ring and the inner step ridge that are in close contact, achieving the technical effects of simple structure and convenience for welding operation. Meanwhile, the pipe joint adopts the design of combination of the lengthened pipe orifice and the built-in annular slot, thereby enhancing the sealing performance and the firmness of the entire pipe joint, achieving the purpose of bearing high pressure.
Description
Technical field
The utility model relates to a kind of tubing, designs the plastic pipe connecting head in a kind of water-treating equipment especially.
Background technique
At present, plastic tube has been widely used in the industrial and agricultural production life, and the most frequently used Placement is the hot melt butt joint between the tubing.Especially the strongest with ultrasonic heat fusion welding applicability, simple to operate and cost economy.But pipe coupling is being carried out in the ultrasonic welding operation process, if the linkage structure design is unreasonable, the tubing discontinuity still can not prison welding be consolidated, and the permeable phenomenon of seepage very easily occurs under the excessive situation of pipe internal pressure.
The model utility content
The utility model is at above problem, provide a kind of simple in structure, welding operation convenient, the plastic pipe linkage structure that can bear big pressure.
A kind of pipe coupling that utilizes ultrasonic welding to connect, comprise body and pipe joint, described body front portion is provided with straight stupefied bulge loop, described pipe joint inwall is provided with the interior ladder bank that adapts with described straight stupefied bulge loop shape, when body insertion tube joint was inner, pipe coupling was welded to connect with the end face that docks of described interior ladder bank by the front-end face of described straight stupefied bulge loop.
Further, described straight stupefied bulge loop front end is provided with the lengthening mouth of pipe, and described pipe joint bottom is provided with annular slot, and when body insertion tube joint was inner, the described lengthening mouth of pipe inserted in the described annular slot.This lengthening mouth of pipe and annular slot combination help strengthening sealing effect, and make the pipe internal pressure not be applied directly to the weld of interior ladder bank and straight stupefied bulge loop, guarantee the soundness that pipeline connects.
Further, the port cross section of the described lengthening mouth of pipe is an arc, and the bottom land of described annular slot also is an arc, and being combined with of this arc shaped surface is beneficial to the increase surface of contact, strengthens sealing effect.
The utility model adopts the straight stupefied bulge loop of contact closely and the design of interior ladder bank to be welded to connect the pipeline joint, reaches simple in structure, welding operation technique effect easily; Simultaneously, adopt the design of the lengthening mouth of pipe and built-in annular groove combination, can strengthen the sealability and the firm degree of whole pipe joint, reach the purpose that to bear big pressure.Whole pipe joint project organization advantages of simple, difficulty of processing is simple and easy and can bear great pressure, and cost economy helps business enterprise expand production.
Description of drawings
Fig. 1 is the utility model apparatus structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing structure of the present utility model and characteristics are described further.
As shown in Figure 1, a kind of pipe coupling that utilizes ultrasonic welding to connect, comprise body 1 and pipe joint 2, body 1 front portion is provided with straight stupefied bulge loop 3, pipe joint 2 inwalls are provided with the interior ladder bank 4 that adapts with straight stupefied bulge loop 3 shapes, when body 1 insertion tube joint 2 inside, pipe coupling is welded to connect with the end face 6 that docks of interior ladder bank 4 by the front-end face 5 of straight stupefied bulge loop 3.
Simultaneously, straight stupefied bulge loop 3 front ends are provided with the lengthening mouth of pipe 7, and pipe joint 2 bottoms are provided with annular slot 8, and when body 1 insertion tube joint 2 inside, the lengthening mouth of pipe 7 inserts in the annular slot 8.These lengthening mouth of pipe 7 and annular slot 8 combinations help strengthening the sealing effect of pipe coupling, and make the pipe internal pressure not be applied directly to the weld of interior ladder bank 4 and straight stupefied bulge loop 3, guarantee the soundness that pipeline connects.
Simultaneously, the port cross section of the lengthening mouth of pipe 7 is an arc, and the groove bottom of annular slot 8 also is an arc, and being combined with of this arc shaped surface is beneficial to the increase area of contact, strengthens sealing effect.
The utility model is not limited to the shaped design of straight stupefied bulge loop and interior ladder bank; the shaped design of the mouth of pipe and annular slot also is not limited to extend; all interfaces by straight stupefied bulge loop and interior ladder bank are welded to connect, and the pipe coupling of using the lengthening mouth of pipe and annular slot to strengthen sealing and soundness all falls within the scope that the utility model is asked for protection.
