Description

Technical Field

[0001] The utility model belongs to the technical field of breathing tubes, and in particular relates to a disassembly and assembly structure of a diving breathing tube. Background Art

[0002] A snorkel is a piece of equipment that allows a snorkeler to breathe while keeping his face in the water. A general snorkel is designed with an open end and a curved tube with a mouthpiece on the other end. The inner diameter of the snorkel is about 2 cm. In terms of material, it can be divided into silicone snorkels and PVC snorkels according to the mouthpiece and accordion tube materials. In terms of design structure, it can be divided into full wet type, semi-wet type, and full dry type. The difference is whether there is a buoyancy air-locking valve or wave-breaking structure on the top of the snorkel.

[0003] The length of the breathing tube is generally fixed, and it can only be used at a corresponding depth. Once it exceeds a certain depth, water will enter the breathing tube. When the diving depth increases, the breathing tube of insufficient length cannot be used, so an extension tube is required. The commonly used extension tube adopts a threaded connection when disassembling and assembling. When disassembling and assembling, it needs to be twisted several times, which is not convenient for quick disassembly and assembly. Utility Model Content

[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. 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.

[0020] like Figure 1 and 2 As shown, a diving breathing tube disassembly and assembly structure includes a main breathing tube 1 and an extension tube 2. A connecting component 3 is provided at the top end of the main breathing tube 1, and a docking component 4 is provided at the bottom end of the extension tube 2. The connecting component 3 and the docking component 4 are snap-connected. The connecting component 3 includes a first enlarged diameter tube 31 fixedly connected to the top end of the main breathing tube 1, and the top end of the first enlarged diameter tube 31 is fixedly connected to a second enlarged diameter tube 32. The interior of the first enlarged diameter tube 31 is fixedly connected to engaging parts 33 equidistantly distributed around the axis of the first enlarged diameter tube 31, and the bottom end of the inner wall of the second enlarged diameter tube 32 is fixedly connected to a rubber pad 34.

[0021] According to the above structure, when in use, one end of the extension tube 2 is inserted into the top end of the main breathing tube 1, and is engaged with the connecting component 3 through the docking component 4, thereby realizing the engaging connection between the main breathing tube 1 and the connecting component 3, which facilitates the disassembly and assembly of the extension tube 2.

[0022] like Figure 2 As shown, the main breathing tube 1, the first expanded diameter tube 31 and the second expanded diameter tube 32 are an integrated structure.

[0023] According to the above structure, the connection strength between the main breathing tube 1 and the connection component 3 is improved, and the service life is increased.

[0024] like Figure 2 and 3 As shown, the engaging member 33 includes an arc-shaped shoe 331 fixedly connected to the inner wall of the first enlarged diameter tube 31 , a slot 332 is provided on one side of the bottom of the arc-shaped shoe 331 , and a wedge-shaped slide groove 333 is provided on one side of the top of the slot 332 .

[0025] According to the above structure, during docking, the engagement piece 33 is engaged with the docking component 4, thereby achieving the connection between the main breathing tube 1 and the extension tube 2.

[0026] like Figure 2-4 As shown, the docking component 4 includes a mounting ring 41 fixedly connected to the side wall of the extension tube 2, and a clamping pad 42 is fixedly connected to the bottom end of the mounting ring 41. The bottom end of the clamping pad 42 is provided with a plurality of concentrically distributed annular protrusions 43, and the plurality of annular protrusions 43 are respectively engaged with a plurality of annular grooves 35. The bottom end of the clamping pad 42 is provided with convex strips 44 equidistantly distributed around the axis of the clamping pad 42. The docking component 4 also includes a bayonet 45 fixedly connected to the bottom of the outer wall of the extension tube 2. There are a plurality of bayonet pins 45, and the plurality of bayonet pins 45 are equidistantly distributed around the axis of the extension tube 2. A wedge-shaped notch 46 matching the wedge-shaped slide groove 333 is provided on one side of the top end of the bayonet pin 45, and a plurality of concentrically distributed annular grooves 35 are provided on the top end of the rubber pad 34.

[0027] According to the above structure, during the specific operation, the bottom end of the extension tube 2 is inserted into the interior of the first expansion tube 31. During the insertion, the bayonet 45 slides downward along the gap between the locking parts 33. When the bottom end of the clamping pad 42 contacts the top end of the rubber pad 34, the annular protrusion 43 is embedded in the corresponding annular groove 35 to improve the sealing between the clamping pad 42 and the rubber pad 34. The extension tube 2 is rotated to drive the bayonet 45 to rotate. The wedge-shaped notch 46 at the top end of the bayonet 45 slides relative to the corresponding wedge-shaped groove 333, thereby squeezing the bayonet 45 downward and driving the extension tube 2 to continue to be inserted, so that the clamping pad 42 and the rubber pad 34 are squeezed against each other, thereby improving the sealing between the two. The setting of the annular protrusion 43 can increase the friction between the top end of the rubber pad 34 and the bottom end of the clamping pad 42, thereby effectively preventing the extension tube 2 from rotating and separating.

[0028] The working principle of the utility model is as follows: when in use, one end of the extension tube 2 is inserted into the top end of the main breathing tube 1, and the docking component 4 is engaged with the connecting component 3, so as to realize the engagement connection between the main breathing tube 1 and the connecting component 3, which is convenient for disassembling and assembling the extension tube 2. During the specific operation, the bottom end of the extension tube 2 is inserted into the inside of the first enlarged diameter tube 31. When inserted, the bayonet pin 45 slides downward along the gap between the engaging parts 33. When the bottom end of the pressing pad 42 contacts the top end of the rubber pad 34, the annular protrusion 43 is embedded in the corresponding annular protrusion 43. The inside of the shaped groove 35 improves the sealing between the clamping pad 42 and the rubber pad 34, and the extension tube 2 is rotated to drive the bayonet 45 to rotate. The wedge-shaped groove 46 at the top of the bayonet 45 slides relative to the corresponding wedge-shaped slide groove 333, thereby squeezing the bayonet 45 downward, driving the extension tube 2 to continue to be inserted, so that the clamping pad 42 and the rubber pad 34 are squeezed against each other, thereby improving the sealing between the two. The setting of the annular protrusion 43 can increase the friction between the top of the rubber pad 34 and the bottom of the clamping pad 42, and effectively prevent the extension tube 2 from reverse rotation and separation.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
