[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 4As shown, a convenient and fast gas charging and discharging accessory comprises a main body 1, a regulating valve 2 is arranged in the middle of the main body 1, and the regulating valve 2 is rotatably connected to the main body 1, a pressure gauge mounting hole 3 is provided on one side of the main body 1, each port of the main body 1 is provided with a buckle groove 4, and an additional buckle is arranged outside the buckle groove 4, the main body 1 is arranged in a Y shape, and the angle between each pipeline of the main body 1 is 120°, the three pipelines of the main body 1 are divided into an air outlet end, an air inlet end and a common end, the regulating valve 2 can only connect the two ports in the main body 1 to each other, and the connection between the regulating valve 2 and the common end in the main body 1 is kept open, and the pressure gauge mounting hole 3 is located at the common end of the main body 1. The end is at the bottom, and the inside of the pressure gauge mounting hole 3 is provided with a thread. The width and depth of the buckle groove 4 should be proportional to the air pressure that the main body 1 can withstand. The greater the air pressure, the wider or deeper the buckle groove 4 is. After the size of the buckle groove 4 is changed, the corresponding buckle also needs to change its size. When it is necessary to inflate or deflate, connect it to the air box and install the pressure gauge to facilitate real-time monitoring of air pressure changes. The regulating valve 2 can be rotated to only deflate for deflation, or the regulating valve 2 can be rotated to inlet to fill the container with gas. After adjusting the cabinet pressure, the connecting buckle can be removed at the connection, which can be conveniently and quickly installed and removed. Due to its small size, it is easy and quick to install and is suitable for various occasions.

[0020] Furthermore, the regulating valve 2 and the main body 1 remain open so that the air pressure inside can be monitored during both intake and exhaust.

[0021] Furthermore, the threads in the pressure gauge mounting hole 3 can enhance the sealing between the main body 1 and the pressure gauge, thereby avoiding measurement errors.

[0022] Furthermore, the buckle groove 4 can limit the pipeline and the buckle, and can also prevent the pipeline from deviating or slipping after it is fixed.

[0023] Furthermore, when the pressure gauge installation hole 3 is connected to the pressure gauge and the pressure gauge needs to be used for a long time, a raw tape can be wrapped in the thread to further enhance the sealing performance.

[0024] Furthermore, when the buckle groove 4 is connected to the external pipeline, a sealing ring can be added inside it, and the outer ring of the sealing ring is located in the middle of the buckle groove 4, so that the pipeline can be prevented from deviating and the sealing performance can be enhanced.

[0025] Furthermore, the length of the buckle that matches the buckle slot 4 should be shorter than the buckle slot 4, so as to avoid shearing force on the pipeline at the junction of the buckle slot 4 and the buckle during connection, thereby protecting the pipeline and extending its service life.

[0026] Furthermore, the buckles in the buckle slot 4 should be connected by screws to prevent the buckles from loosening.

[0027] Furthermore, the regulating valve 2 is specifically configured as a three-way valve, and an L-shaped through hole is provided in the sphere inside the regulating valve 2, and the angle of the L-shaped through hole is 120°.

[0028] Furthermore, whether to add a limit device between the regulating valve 2 and the main body 1 can be determined according to the operating specifications. The limit device can ensure that the common end of the main body 1 is always connected to the regulating valve 2, so that it can always be connected when flushing and releasing gas. Without the limit device, the intake pipe and the exhaust pipe can be connected, so that the gas from both places can be discharged through the intake and exhaust pipes at the same time.

[0029] Furthermore, the pressure gauge installation hole 3 can not only be used to install an external pressure gauge, but also can be removed when exhausting to add an outlet, thereby speeding up the exhaust speed.

[0030] Working principle: When using this convenient and fast inflation and deflation accessory, first, dock the connecting pipe with the corresponding port of the main body 1, lock and seal the docking with the buckle at the position of the buckle groove 4, then install the pressure gauge into the pressure gauge installation hole 3, and then observe the pressure gauge. If it is deflated, adjust the regulating valve 2 to deflate, observe the pressure gauge quickly to the required air pressure, and slowly reduce the regulating valve 2 until it is closed; if it is inflated, adjust the regulating valve 2 to inflate, observe the pressure gauge quickly to the required air pressure, and slowly reduce the regulating valve 2 until it is closed; if it is necessary to deflate and inflate at the same time, adjust the regulating valve 2 to deflate, observe the pressure gauge quickly to the standard air pressure, and slowly reduce the regulating valve 2, and then adjust the regulating valve 2 to inflate, observe the pressure gauge quickly to the required air pressure, and slowly reduce the regulating valve 2 until it is closed. This is the working principle of this convenient and fast inflation and deflation accessory.
