Description

A kind of air hose converting interface

Technical field

The utility model relates to a kind of air hose converting interfaces.

Background technique

Under currently available technology, the smoke evacuation of kitchen ventilator is then discharged out by directly connecting with check-valves after air hose, is passed The method of system is to be fixed after being inserted in check-valves by air hose and then being fastened by hose clamp by the winding of aluminium foil glass fiber fabric, This method it is very troublesome with it is time-consuming, and leakproofness will be depending on the leakproofness of hose clamp and aluminium foil glass fiber fabric.

In addition, when the air hose or independent cut-off wind pipe of two sections of different-diameters need to be connected on the different air port of bore, it is past It is past to need air hose conversion to realize, and traditional mode is: the different air hose of bore, is that small-bore air hose is filled in heavy caliber wind Pipe, or a cut-off wind pipe is connected on air port with by way of tying up, the leakproofness of both modes is all bad, and installs Difficulty is big, also unsightly.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of air hose converting interface.

The air hose converting interface of the utility model, including central tube, the outer wall of the central tube is equipped with small-bore intubation, small The bottom end of gauge cannula is equipped with the heavy caliber intubation being located at outside central tube, and the interior groove bottom of heavy caliber intubation is equipped with a circle circumference Partition wall, heavy caliber intubation outer wall on by positon of near bottom be equipped with several equally distributed L v notch vs.

The inside that heavy caliber is intubated is divided into two annular grooves by the air hose converting interface of the utility model, the circumference partition wall, circle The bottom face of all partition walls is higher than the bottom face of heavy caliber intubation.

Compared with prior art the utility model has the following beneficial effects: the air hose converting interface structure novel of the utility model, The different intubation of the two-port outer wall mulberry design diameter of central tube, heavy caliber intubation outer wall on design have L v notch v, installation side Just, good airproof performance.

Detailed description of the invention

Fig. 1 is a kind of one of structural schematic diagram of air hose converting interface described in the utility model embodiment；

Fig. 2 is a kind of second structural representation of air hose converting interface described in the utility model embodiment.

In figure:

1, central tube；2, small-bore intubation；3, heavy caliber is intubated；4, circumference partition wall；5, L v notch v.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.

As shown in Figs. 1-2, a kind of air hose converting interface, including central tube 1, the outer wall of the central tube 1 are equipped with small-bore Intubation 2, the bottom end of small-bore intubation 2 are equipped with the heavy caliber intubation 3 being located at outside central tube 1, the interior groove bottom of heavy caliber intubation 3 Equipped with a circle circumference partition wall 4, several equally distributed L v notch vs 5 are equipped with by positon of near bottom on the outer wall of heavy caliber intubation 3.

The inside of heavy caliber intubation 3 is divided into two annular grooves by the air hose converting interface of the utility model, the circumference partition wall 4, The bottom face of circumference partition wall 4 is higher than the bottom face of heavy caliber intubation 3.

The air hose adapter of the utility model, when specifically used, the inner wall of small-bore intubation 2 is inserted into air hose, because existing There is air hose all to post PVC patch, therefore air hose can be good at being bonded with small-bore intubation 2, and provide the power of anti-dropout, it is another End heavy caliber be intubated on 3 outer walls the L v notch v that designs and check-valves can fast and convenient completion connect (check valve design card It is convex, after in check-valves insertion heavy caliber intubation 3, in card convex insertion L v notch v and rotates, realize the lock of card convex and L v notch v Tightly).And other cumbersome external fastenings are not needed.

The air hose converting interface structure novel of the utility model, the two-port outer wall mulberry design diameter of central tube is different to insert Pipe, design has a L v notch v on the outer wall of heavy caliber intubation, L v notch v can be clasped, and then realize the wind of different bores Pipe connection, easy for installation, good airproof performance.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into modification.
