[0002] In recent years, with the improvement of people's living standards and the strengthening of the public's awareness of physical fitness, the demand for diving snorkels for swimming, diving and other sports in coastal areas has increased. For diving sports, the snorkel is an essential equipment for scuba diving and snorkeling. It is necessary to use a snorkel to ensure safety during recreational diving. It allows you to breathe more easily on the water surface without lifting your head out of the water, and saves air sources on the water surface.

[0003] The diving breathing tube structure design in the prior art is poor. The single-loop structure at the bend is easily bent inward when hit, which hinders breathing and threatens the life safety of divers. In addition, the diving breathing tube is long and most of the tube body is an integrated structure, resulting in a large overall volume and occupied space, which is not conducive to the storage and transportation of the diving breathing tube. Utility Model Content

[0004] The utility model aims to provide a diving breathing tube bend and assembly structure. By improving the structure of the diving breathing tube bend, the bend is prevented from being bent inward due to collision, the bending moment is larger, the toughness is better, and the diving breathing tube can be disassembled and assembled together, shortening the length of the breathing tube, reducing the overall occupied area, and being more convenient for transportation and storage.

[0005] The technical solution adopted by the utility model is as follows:

[0007] A drainage bin is fixedly connected to the bottom of the mouthpiece, and the drainage bin is fixedly connected to the fixing plate.

[0008] The inner wall of the connecting column is rotatably threadedly connected with a first air pipe, and one end of the first air pipe is rotatably threadedly connected with a second air pipe.

[0009] The filling caps are movably plugged into the inner walls of the first and second trachea when the structure is folded.

[0010] One end of the clamping hand is fixedly connected with an insert head.

[0011] One end of the inserting head is elastically connected with a spring ball, and the inner wall of the clamping hand is elastically connected with a pressing block.

[0012] The pressing block and one end of the spring ball are both provided with a wedge-shaped inclined surface, and the two wedge-shaped inclined surfaces are arranged to fit each other inside the clamp.

[0013] The clamping hands are respectively movably connected with the first trachea and the second trachea when the structure is folded.

[0014] A bent pipe of a diving breathing tube comprises a bent pipe, wherein an outer wall of the bent pipe is provided with H-shaped grooves in an array, a connecting column is fixedly connected to the bent pipe, and a fixing plate is fixedly connected to the bent pipe.

It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0022] like Figure 1-3As shown, a curved pipe and assembly structure of a diving breathing tube, including a curved pipe 104, the outer wall of the curved pipe 104 is provided with an array of H-shaped grooves 114 for connecting with the curved pipe 104, including a connecting column 105 and a fixing plate 102, a drainage chamber 101 is fixedly connected to the bottom of the mouthpiece 1, the drainage chamber 101 is fixedly connected to the fixing plate 102, the fixing plate 102 is fixedly connected to the curved pipe 104, a screw 109 is symmetrically fixedly connected to one side of the outer wall of the fixing plate 102, a stuffing cap 103 is rotatably screwed on the outer wall of the screw 109, an air pipe 106 is rotatably screwed on the inner wall of the connecting column 105, an air pipe 106 is rotatably screwed on one end of the air pipe 106, and the stuffing cap 103 is movably plugged into the inner walls of the air pipe 106 and the air pipe 2 107 when the structure is folded.

[0023] See attached Figure 2-3 The outer wall of the connecting column 105 is symmetrically and staggeredly provided with embedding grooves 111, and the connecting column 105 is movably connected with a clamping hand 108 through the embedding grooves 111. The connecting column 105 is fixedly connected to the bent pipe 104, and the outer wall of the connecting column 105 is symmetrically provided with a clamping groove 110 for the clamping hand 108 to be embedded and engaged. One end of the clamping hand 108 is fixedly connected with an embedding head 115, and one end of the embedding head 115 is elastically connected with a spring ball 112. The inner wall of the clamping hand 108 is elastically connected with a pressing block 113, and one end of the pressing block 113 and the spring ball 112 are both provided with wedge-shaped inclined surfaces, and the two wedge-shaped inclined surfaces are arranged in a fit inside the clamping hand 108. When the structure is folded, the clamping hand 108 is movably engaged with the trachea 1 106 and the trachea 2 107 respectively.

[0024] According to the above structure, the air pipe 107 and the air pipe 106 are rotated to separate them from the connecting column 105, the bent pipe 104 is laid flat and the clamping hand 108 is pulled out, the inserting head 115 is inserted into the embedding groove 111, the spring ball 112 is engaged with the inside of the embedding groove 111, and the removed air pipe 106 and the air pipe 107 are inserted into the plugging cap 103, and the plugging cap 103 is rotated to slide along the outer wall of the screw 109 until one end of the air pipe 106 and the air pipe 107 is engaged with the clamping hand 108.

One end of 107 is inserted into the clamp 108. Compared with the existing single-loop structure, the H-shaped structure of the H-shaped groove 114 can prevent the bent pipe 104 from folding inward.
