The following detailed description of the invention will be further described in conjunction with the above-identified drawings.
Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Several embodiments of the invention are given in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, the embodiment of the utility model provides a carry plastic tubing connection structure, including two sections bodys 1 and the butt joint section of thick bamboo 2 of setting between two bodys 1, butt joint section of thick bamboo 2 and the 1 inner wall of body grafting adaptation, butt joint section of thick bamboo 2 external diameter equals or slightly is greater than the 1 internal diameter of body. The coaxial rigid coupling of butt joint section of thick bamboo 2 length direction's middle part outer wall has butt joint ring 3, 3 axial both sides of butt joint ring all set up with caulking groove 4 of 1 tip gomphosis adaptation of body, and butt joint ring 3 is provided with sealing washer 8 in caulking groove 4, is provided with on the butt joint ring 3 to be used for ordering about the locking mechanism of body 1 support tightly on 4 diapalls of caulking groove.
As shown in fig. 1, the locking mechanism includes a thread cylinder 5 screwed on the docking ring 3, the thread cylinder 5 can be selected to be screwed on the wall of the slot 4, and the thread cylinder 5 is screwed on the wall of the docking ring 3. The inner wall of the threaded cylinder 5 is provided with a bulge 6 for abutting against the pipe body 1, and one side of the bulge 6, which is far away from the threaded cylinder 5, is provided with a rough part.
Thereby when two pipe fittings of butt joint, insert two pipe fittings respectively earlier with the both ends of a butt joint section of thick bamboo 2 to make the pipe fitting tip imbed the caulking groove 4 as far as possible, two screw thread section of thick bamboos 5 on the rotatory butt joint ring 3 of rethread can make two screw thread section of thick bamboos 5 be close to each other, and at this in-process, arch 6 on the screw thread section of thick bamboo 5 supports tightly on the pipe fitting outer wall and drives the pipe fitting tip and imbed the caulking groove 4 gradually, has realized the stable sealing connection of two pipe fittings. And when needs are adjusted pipeline, can two reverse rotation screw thread section of thick bamboo 5 to with the pipe fitting from docking a section of thick bamboo 2 top spin, can realize two free dismantlements of the pipe fitting after the butt joint, thereby it is more nimble convenient when adjusting pipeline.
In some embodiments, the plurality of protrusions 6 are arranged and distributed in a circumferential array at equal intervals along the axial direction of the threaded cylinder 5, and the shape of the protrusions 6 may be a rectangular shape, a triangular pyramid shape, or a drop shape, but any shape can be used to achieve an effective fastening effect on the outer wall of the tube body 1. The rough part is frosted on the outer surface of the bulge 6 to increase the static friction coefficient between the bulge 6 and the pipe body 1, so that the threaded cylinder 5 can effectively drive the pipe body 1 to move towards the caulking groove 4 when rotating on the butt joint ring 3.
In other embodiments, the protrusion 6 is a unitary ring, and the rough portion is a tooth protrusion integrally formed on the protrusion 6, so that the protrusion 6 can drive the tube body 1 to move toward the caulking groove 4 when rotating along with the threaded barrel 5.
In order to improve the tightness of the pipe body 1 when being connected with the docking barrel 2, as shown in fig. 1, the outer wall of the docking barrel 2 is provided with a plurality of anti-slip grooves 7, and the distance between two adjacent anti-slip grooves 7 gradually decreases from the end part to the middle part of the docking barrel 2. Therefore, when the threaded cylinder 5 rotates, the anti-slip groove 7 can play a role in increasing friction force, so that the end part of the pipe body 1 can be kept stably connected with the butt joint cylinder 2 after being tightly abutted to the caulking groove 4.
In other embodiments, can also continue to set up a butt joint section of thick bamboo 2 as its external diameter and be the trend of crescent by its tip to its middle part, wear to establish when body 1 tip with a butt joint section of thick bamboo 2, can carry out certain degree heating to the pipe fitting of plastics material for body 1 tip appears the cover after slightly softening and establishes on butt joint section of thick bamboo 2 again, so that can stably attach on the butt joint pipe after making body 1 cool off, sealed effect is better.
Meanwhile, in order to facilitate the rotation of the threaded cylinder 5 when the pipe body 1 is butted, the outer wall of the threaded cylinder 5 is provided with an auxiliary structure, and in one embodiment, the auxiliary structure is an anti-skid thread (not shown in the figure) arranged on the outer wall of the threaded cylinder 5.
In other embodiments, the auxiliary structure is a lug integrally formed on the outer wall of the threaded cylinder 5.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
