Abstract
The utility model discloses a combined venting pipeline. The combined venting pipeline comprises a first pipeline and a pipeline in the same thickness; the end surface of the first pipeline is provided with a first lug and a first groove; the end surface, corresponding to the first pipeline, of the second pipeline is provided with a second groove and a second lug which are respectively matched with the first lug and the first groove for use. The combined venting pipeline is portable in construction, timesaving, laborsaving, fast to assemble and mount, good in sealing property, simple in construction process, firm in connection and stable in connection and high in venting efficiency.
Description
Technical field
The utility model relates to ventilation equipment, specifically a kind of combined ventilation equipment.
Background technique
No matter be outdoor or indoor, the ventilation equipment equipment that is all absolutely necessary, and ventilation duct is exactly the necessary assemblies of composition ventilation equipment, most ventilation ducts adopt iron duct, and glass wind pipeline is made, most of once-throughs, but because ventilation duct sometimes needs oversize, quality is wayward, installs inconveniently, oversizely too heavily causes carrying inconvenience, not removable, the ventilation duct of the dismounting then having easily leaks out again, and sealing effect is poor, and quality can not be guaranteed.
Model utility content
The purpose of this utility model is the deficiency existing for prior art, and a kind of combined ventilation duct is provided.
For realizing above-mentioned model utility object, the technical solution adopted in the utility model is a kind of combined ventilation duct, comprises the first pipeline and second pipe that thickness is identical, and the end face of described the first pipeline is provided with the first projection and the first groove; The described second pipe end face corresponding with the first pipeline is provided with the second groove and the second projection that use with the first projection and the first groove fit.
The utility model can be realized the dismounting of ventilation duct by the connection of draw-in groove and projection, convenient installation carried.
Wherein, for it is installed firmly, be respectively equipped with the first fixture block and the first draw-in groove on described the first projection and the first groove, described the second groove and the second projection are provided with the second draw-in groove and the second fixture block that are used in conjunction with the first fixture block and the first draw-in groove.
Wherein, more laborsaving when making to install, the end face of described the first pipeline and second pipe is oblique tangent plane.
Wherein, in order to guarantee the sealing after ventilation duct combination, the internal diameter of described the first pipeline is greater than second pipe, the ventilation duct forming afterwards in installation is like this vent hole with step shape, blow to the wind of the first pipeline from second pipe, because being blows to small-bore wind from heavy caliber, so can not produce the situation of leaking out, good seal performance.
Beneficial effect: compared with prior art, the utlity model has following advantage: combined ventilation duct of the present utility model, easy to carry when construction, time saving and energy saving, group and quick for installation, and good seal performance, construction process is simple, be connected firmly, stable, drafting efficiency is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model ssembly drawing.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, the present embodiment is implemented under take technical solutions of the utility model as prerequisite, should understand these embodiments and only be not used in restriction scope of the present utility model for the utility model is described.
As shown in Figure 1, a kind of combined ventilation duct, comprises the first pipeline and second pipe that thickness is identical, and the end face of described the first pipeline is provided with the first projection 1 and the first groove 2; The described second pipe end face corresponding with the first pipeline is provided with the second groove 3 and the second projection 4 that are used in conjunction with the first projection 1 and the first groove 2.
Wherein, on described the first projection 1 and the first groove 2, be respectively equipped with the first fixture block and the first draw-in groove, described the second groove and the second projection are provided with the second draw-in groove and the second fixture block that are used in conjunction with the first fixture block and the first draw-in groove.
Wherein, the end face of described the first pipeline and second pipe is oblique tangent plane.
Wherein, the internal diameter of described the first pipeline is greater than second pipe.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
