[0004] To achieve the above technical purpose, the utility model adopts a kind of gas hose structure with flush inner tube and joint, including gas inner tube and gas hose joint, the gas inner tube is sleeved in the inner hole of gas hose joint, the outer wall of the gas inner tube and the inner wall of the inner hole of gas hose joint are fixedly connected by heat melting mode, the front end surface of the gas inner tube and the front end surface of gas hose joint flush structure.

[0005] Further, the outer wall of the front part of the gas inner tube is provided with a positioning baffle, and the front end of the inner hole of the gas hose joint is provided with a positioning slot structure that can be completely inserted into the positioning baffle when the front end surface of the gas inner tube and the front end surface of the gas hose joint are flush.

[0006] As a preferred embodiment of the utility model, the number of the positioning baffle is two or three, when the number of the positioning baffle is two, they are arranged at a position of 180° from each other, and when the number of the positioning baffle is three, they are arranged at a position of 120° from each other.

[0007] Further, the inner wall of the gas inner tube is uniformly coated with a layer of nanometer polymer coating.

[0008] After the above technical improvement, the utility model has the following advantages:

[0009] 1. The utility model adopts the structure that the front end surface of the gas inner tube and the front end surface of the gas hose joint are flush, which can effectively prevent gas leakage caused by the existence of unclosed parts when the joint is connected with the gas stove.

[0010] 2. The utility model discloses a positioning baffle is set to the outer wall of the front part of gas inner tube, and the positioning slot structure that can insert the positioning baffle is set to the front end of gas hose joint inner hole, make when installing, the front end surface of gas inner tube and the front end surface of gas hose joint flush more convenient.

[0011] 3. The utility model discloses a layer of nanometer polymer coating on the inner wall of gas inner tube, can make gas inner tube more ageing -resistant, prolong the life. DRAWINGS

[0012] Figure 1 The utility model discloses a structure cross -section view as the utility model discloses.

[0013] Figure 2 The utility model discloses positioning baffle and positioning slot structure structure schematic diagram in the utility model discloses.

[0014] Among them, 1, gas inner tube;2, gas hose joint;3, positioning baffle;4, positioning slot structure;5, nanometer polymer coating. CONCRETE IMPLEMENTING METHOD

[0015] The utility model will be further explained below combining with the drawings and concrete implementing mode.

[0016] Combining Figure 1 Know, a kind of gas hose structure of inner tube and joint flush, including gas inner tube 1 and gas hose joint 2, gas inner tube 2 is sleeved in the inner hole of gas hose joint 1, and the outer wall of gas inner tube 1 and the inner wall of the inner hole of gas hose joint 2 are formed fixed connection by heat melting mode, and the front end surface of gas inner tube 1 and the front end surface of gas hose joint 2 are flush structure.

[0017] The above structure of the utility model adopts the flush structure of the front end surface of gas inner tube 1 and the front end surface of gas hose joint 2, can be good at preventing gas hose joint 2 and gas stove connection when there is not closed part and lead to gas leakage.

[0018] By Figure 2 Know, positioning baffle 3 is equipped in the outer wall of the front part of gas inner tube 1, and when the front end surface of gas inner tube 1 and the front end surface of gas hose joint 2 are flush structure, positioning slot structure 4 of positioning baffle 3 can be inserted completely.

[0019] In the utility model, the number of the positioning baffle 3 is two or three, when the number of the positioning baffle 3 is two, the positioning baffle 3 is arranged at 180° position, when the number of the positioning baffle 3 is three, the positioning baffle 3 is arranged at 120° position. Of course, correspondingly, when the number of the positioning baffle 3 is two, the number of the positioning slot structure 4 is also two, when the number of the positioning baffle 3 is three, the number of the positioning slot structure 4 is also three.

[0020] The above structure of the utility model sets the positioning baffle 3 on the outer wall of the front part of the gas inner pipe 1, and sets the positioning slot structure 4 capable of inserting the positioning baffle 3 on the front end of the inner hole of the gas hose joint 2, so that when installing, it is more convenient that the front end face of the gas inner pipe 1 and the front end face of the gas hose joint 2 are flush.

[0021] Continue to see Figure 2 On the inner wall of the gas inner pipe 1, a layer of nano polymer coating 5 is evenly coated. The nano polymer coating 5 coated on the inner wall of the gas inner pipe 1 can make the gas inner pipe 1 more resistant to aging and prolong the service life.

[0022] The above only is the preferred implementation of the utility model, it should be pointed out, for the ordinary skilled person in the art, without departing from the technical principle of the utility model, still can make several improvements and variations, these improvements and variations also should be regarded as the protection range of the utility model.
