Description

Tee connector and vacuum packaging bag Technical Field The utility model relates to the field of tee connectors, in particular to a tee connector and a vacuum packaging bag. Background The three-way connector is a pipe fitting for connecting a plurality of pipes in a pipe system, and in the prior art, an assembled frame usually uses the three-way connector to connect a plurality of support rods to form a support frame. Currently, chinese patent with bulletin number CN 222950631U and bulletin day 2025, month and 06 proposes a three-way connector, which includes a body having three connection pipes, at least one of which is provided with a clamping portion, the clamping portion includes a bayonet circumferentially opened on the connection pipe, the elastic clamping member can slide in the bayonet along the circumferential direction of the connection pipe, and the elastic clamping member can slide in the bayonet along the circumferential direction of the connection pipe. When the three-way connecting piece is used, the elastic clamping pieces of the connecting rod are in circumferential angle deviation, and the connecting rod can be rotated at the moment, so that the elastic clamping pieces slide in corresponding bayonets, two elastic clamping pieces can be respectively clamped with bayonets corresponding to the three-way connecting pieces at two ends, and the three-way connecting piece and the connecting rod are assembled. To above-mentioned correlation technique, when the connecting rod is connected with the connecting pipe of tee bend connecting piece, the connecting rod can insert tightly inside the connecting pipe for the outer peripheral face of connecting rod is sealed the setting with the inner peripheral face of connecting pipe, makes the inside independent sealed space that forms of connecting rod and connecting pipe, nevertheless when supporting the braced frame that becomes with this kind of tee bend connecting piece equipment in vacuum packaging bag or vacuum environment inside, the inside air of tee bend connecting piece is difficult for discharging with the connecting rod inside, leads to the packing in vacuum low, the inside easy pollution that produces of packing. Disclosure of utility model In order to enable the three-way connecting piece to be used as a part of the supporting frame to support in an environment needing vacuumizing, air in the three-way connecting piece and the supporting frame can be better discharged, and the three-way connecting piece and the vacuum packaging bag are provided. In a first aspect, the utility model provides a three-way connecting piece, which adopts the following technical scheme: A three-way connecting piece comprises three connecting pipes, wherein one ends of the three connecting pipes are fixedly connected to a junction, the three connecting pipes are communicated with each other, and an air port is formed in the inner side of the junction. By adopting the technical scheme, the three-way connecting piece and the connecting rod are used for splicing to form the supporting frame, then the sealing bag is sleeved on the supporting frame formed by splicing, then the product is placed inside the supporting frame, finally the sealing bag is vacuumized, the product is vacuum-packed inside the supporting frame, when the sealing bag is vacuumized, air inside the connecting rod is discharged from the air port at the junction, and meanwhile the packaging bag is gradually folded towards the central position of the supporting frame, so that the product is fixed at the middle position of the supporting frame. Therefore, the air port is formed in the middle of the three-way connecting piece, and when vacuumizing is performed, air in the three-way connecting piece and the supporting frame can be discharged from the air port, so that the air remained in the sealing bag is reduced, and the vacuum degree of the sealing bag can be improved. Optionally, a chamfer is arranged at the inner edge of the connecting pipe. After the sealing bag is sleeved on the supporting frame formed by combining the three-way connecting piece and the connecting rod, when the connecting rod is plugged into the connecting pipe on the three-way connecting piece again, the sealing bag can move towards the inside of the connecting pipe along with the movement of the connecting rod, so that the sealing bag is clamped in a gap between the connecting rod and the connecting pipe, and the sealing bag is easy to damage. Through adopting above-mentioned technical scheme, the chamfer that the connecting pipe inward flange department set up makes the outer peripheral face of connecting rod and the outer peripheral face of connecting pipe have certain difference in height, and when the sealing bag moved to connecting rod and connecting pipe grafting position department along with the connecting rod, because the existence of difference in height, make the sealing bag be difficult for grafting in the connecting p
