Abstract
The utility model discloses a connecting piece for thick and fine tubes. A connecting piece main body is divided into a thick end and a fine end, wherein clamping posts at the two ends of the main body are used for connecting the main body with tube pieces; the connecting piece main body is gradually thinned from the thick end to the fine end; the tube wall thickness of the connecting piece body gradually increases from the thick end to the fine end. The connecting piece for the thick and fine tubes has the beneficial effects that the integral structure is simple; the tube wall thickness of the connecting piece main body gradually increases from the thick end to the fine end, so that the bearing capacity of the fine end is improved; meanwhile, a wear-resistant layer is arranged on the inner wall of the connecting piece, so that the firmness and stability of the whole pipeline are improved, and the service life of a device is prolonged.
Description
Technical field
The utility model relates to concrete conveyance tubing technical field, relates in particular to a kind of thickness tubular union.
Background technique
Concrete delivery pipe is the necessary equipment that the technical fields such as building are used for carrying out concreting; because requirement of engineering; often use the conversion between the thickness pipeline; this will use the thickness tubular union; existing thickness tubular union such as is at the body of wall thickness; such link is owing to the suffered pressure of taper end is larger, and wearing and tearing wait so that link damages easily, causes whole pipeline to be stopped work.
The model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of durable thickness tubular union.
The technological scheme that the utility model adopts is: a kind of thickness tubular union, described connector main body is divided into butt end and taper end, two ends are provided with card column and are used for and being connected of pipe fitting, and connector main body is gradually thin to taper end by butt end, and the pipe thickness of described connector main body is gradually thick to taper end by butt end.
As preferably, the tube wall inboard of described connector main body is provided with wearing layer.
As preferably, described wearing layer is the inboard that equal thickness is arranged on the connector main body tube wall.
As preferably, described card column is provided with the installation groove.
As preferably, described installation groove is dovetail groove.
Compared with prior art, the beneficial effects of the utility model are: overall structure is simple, the pipe thickness of connector main body is gradually thick to taper end by butt end, increased the ability to bear of taper end, inwall is provided with wearing layer simultaneously, improve the soundness and stability of whole pipeline, prolonged the working life of equipment.
Description of drawings
In order to be illustrated more clearly in the technical solution of the utility model, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural drawing of the present utility model.
Among the figure: 1 link body, 2 card columns, 3 wearing layers, 4 install groove.
Embodiment
In order more clearly to understand the technical solution of the utility model, below in conjunction with accompanying drawing the utility model is further specified.
A kind of thickness tubular union as shown in Figure 1, described connector main body 1 is divided into butt end and taper end, two ends are provided with card column 2 and are used for and being connected of pipe fitting, connector main body 1 is gradually thin to taper end by butt end, the pipe thickness of described connector main body 1 is gradually thick to taper end by butt end, increased the ability to bear of connector main body taper end, the tube wall inboard of described connector main body 1 is provided with the wearing layer 3 of equal thickness, the soundness and stability of whole pipeline have been improved, prolonged the working life of equipment, card column 2 is provided with installs groove 4, is preferably dovetail groove, is convenient to the connection between the pipe fitting.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
