The pipeline connecting piece provided by the utility model realizes multi-angle adjustment, meets wider application requirements, can effectively prevent smoke from flowing back, and has a good smoke discharging effect.
Description
Technical Field
The utility model relates to the technical field of ventilation pipelines, in particular to a ventilation pipeline connecting piece with an angle adjusting function.
Background
The connection between the ventilation pipelines sometimes needs to use pipeline connectors, and particularly when the direction of the ventilation pipelines is changed, the two ventilation pipelines can be adjusted through the connectors, so that the pipeline connectors are required to have an angle adjusting function, the angles of the traditional pipeline connectors are fixedly designed and cannot be adjusted, and the wider application cannot be satisfied; in the exhaust process of the conventional ventilation pipe, gas in the pipeline is easy to flow backward, so that the smell returning phenomenon is caused, and the exhaust of the pipeline is not smooth.
Disclosure of Invention
The utility model aims to provide a ventilating duct connecting piece with an angle adjusting function, so as to solve the problems in the background art.
In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a ventilation duct connecting piece with angle regulation function, includes preceding fixed pipe, back fixed pipe and sets up the connecting pipe between preceding fixed pipe, back fixed pipe, the connecting pipe is flexible pipe that has flexible elasticity, be fixed with the locating piece on preceding fixed pipe and the back fixed pipe respectively, be connected with the gag lever post between the locating piece, be provided with the back flow prevention pipe in the back fixed pipe, the air inlet and outlet end of back flow prevention pipe is loudspeaker formula, and the air current passageway in the middle is the arc structure.
The air flow channel is of an S-shaped structure.
The stop lever may be an elastic stop lever.
The backflow prevention pipe is installed in the rear fixing pipe through magnet adsorption.
Compared with the prior art, the utility model has the following beneficial effects: the connecting pipe in the ventilating pipe connecting piece is the telescopic pipe with telescopic elasticity, the telescopic pipe can enable the pipe connecting piece to realize multi-angle adjustment, the wider application requirements are met, the backflow prevention pipe is arranged in the rear fixing pipe, the air inlet end and the air outlet end of the backflow prevention pipe are of a horn shape, air inlet can realize wind gathering and flow guiding, air outlet can realize flow velocity reduction, vibration caused by too high flow velocity is avoided, the middle air flow channel is of an arc-shaped structure, and after air passes through the arc-shaped air flow channel, air is difficult to flow back due to the radian of the air flow channel, so that the backflow of smoke can be effectively prevented, and the smoke discharging effect is good.

fig. 1 is a schematic structural view of embodiment 1 of the present utility model;
fig. 2 is a schematic structural view of embodiment 2 of the present utility model;
in the figure: 1, fixing a pipe; 2, connecting pipes; 3, fixing the tube; 4, positioning blocks; 5, a limit rod; 6, backflow preventing pipe; 7 air flow channels.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1, the present utility model provides the following technical solutions: the utility model provides a ventilation duct connecting piece with angle regulation function, includes preceding fixed pipe 1, back fixed pipe 3 and sets up connecting pipe 2 between preceding fixed pipe 1, back fixed pipe 3, connecting pipe 2 is for having flexible pipe, be fixed with locating piece 4 on preceding fixed pipe 1 and the back fixed pipe 3 respectively, be connected with gag lever post 5 between the locating piece 4, be provided with anti-return pipe 6 in the back fixed pipe 3, the business turn over gas end of anti-return pipe 6 is loudspeaker, and the air current passageway 7 in the middle is the arc structure.
The air flow channel 7 is of an S-shaped structure.
The limiting rod 5 can be an elastic limiting rod, can be matched with the connecting pipe 2, and when the connecting pipe 2 is bent, the limiting rod 5 can also be bent, so that the installation limiting is utilized.
The backflow prevention pipe 6 is installed in the rear fixing pipe 3 through magnet adsorption, and is convenient to detach, maintain and install.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
