Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description will be given with reference to the accompanying drawings and preferred embodiments in order to provide the best mode, structure, features and effects according to the present invention.
Referring to fig. 1 and 2, the air pressure sealing type pipe of the first embodiment of the present invention includes a housing 1 and an air bag 2, the housing 1 is provided with a mounting hole 11, the air bag 2 is provided with an inflating nozzle 21 corresponding to the mounting hole 11, an inflating cavity 22 is formed in the air bag 2, and the inflating cavity 22 is inflated by the inflating nozzle 21 so as to expand the air bag 2. The housing 1 is made of metal or plastic.
The shell 1 is tubular, two ends of the shell 1 are provided with limiting rings 12, and the air bag 2 is positioned between the pair of limiting rings 12. The air bag 2 is provided with the through hole 3, the size of the through hole 3 is changed by inflating the air bag 2, and the pipe hoop is suitable for connecting pipelines with different calibers because the aperture of the through hole 3 is changed along with the change of the air pressure of the inflation cavity 22. The inner diameter of the limiting ring 12 is equal to or larger than the diameter of the through hole 3, and the inner diameter of the limiting ring 12 limits the upper limit of the caliber of the pipeline.
The airbag 2 is made of rubber. When the air bag 2 is installed, the air bag 2 is made of rubber, so that the air bag can be folded to pass through the limiting ring 12, and then the inflating nozzle 21 is fixed in the installation hole 11 to complete installation.
In the use process, firstly, the pipeline is inserted into the two ends of the pipe hoop, the end part of the pipeline is contacted with the baffle ring 23, then the air bag 2 is inflated through the inflating nozzle 21, the through hole 3 becomes small after the air bag 2 is inflated, so that the air bag is tightly attached to the outer surface of the pipeline, meanwhile, the pipeline is fixed by high air pressure in the inflating cavity 22, and after the air bag is stopped, the inflating nozzle 21 is automatically closed, so that the inflating cavity 22 keeps air pressure. The fixed air bag 2 plays a role in sealing and fixing. The pipe clamp is used for temporary connection of pipelines or connection of pipelines with lower pressure requirements.
Referring to fig. 3, in a second embodiment of the present invention, the housing 1 is further provided with a protective cap 4 for sealing the mounting hole 11, and the protective cap 4 is in threaded connection with the mounting hole 11. When the pipe is connected, the air pressure of the air inflation cavity 22 is slowly reduced along with the time, and the protective cap 4 plays a role of slowing down the reduction of the air pressure, so that the service time is prolonged.
Referring to fig. 4, in a third embodiment of the present invention, a stop ring 23 is disposed in the middle of the inner surface of the airbag 2, and the stop ring 23 can ensure that the end of the pipeline is located in the middle of the pipe clamp. The inner surface of the air bag 2 is provided with a pattern for increasing friction. When fixed, the decorative pattern plays the effect of preventing pulling out and increasing frictional force.
Referring to fig. 5 and 6, in a fourth embodiment of the present invention, the housing 1 is a 90 ° elbow, the air bags 2 are respectively disposed at two ends of the housing 1, and the housing 1 is provided with a pair of mounting holes 11 corresponding to the inflating nozzles 21 of the air bags 2. The inner surface of the balloon 2 has a plurality of folds 24 which are inclined outwardly.
When connecting, 2 inflation extrusion pipelines of gasbag make fold 24 and the contact of pipeline surface, because fold 24 leans out, consequently fold 24 non-deformable has better anti-pulling effect, even because too big or pipeline displacement make gasbag 2 take place to warp owing to pressure, also be gasbag 2 is whole to be out of shape, and not make a plurality of folds 24 warp to keep better leakproofness.
The housing 1 may also be of the three-way type or the four-way type, thereby facilitating more complex pipe connections.
The utility model discloses in, gasbag 2 is equipped with through-hole 3, through aerifing the size that changes through-hole 3 for gasbag 2, and when connecting tube, 2 extrudees of gasbag is located the pipeline of through-hole 3 to realize fixing, have simple structure, aperture adjustable beneficial effect.
The utility model discloses in, for aerifing chamber 22 in the gasbag 2, aerify for aerifing chamber 22 through charging connector 21 and make gasbag 2 inflation to fixed and sealed pipeline, this ferrule has simple structure, convenient to use, sealed effectual beneficial effect consequently.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with the preferred embodiment, it is not limited to the present invention, and any skilled person can make modifications or changes equivalent to the above embodiments without departing from the scope of the present invention, but all the modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are within the scope of the present invention.
