[0031] Example 1:

[0032] like Figures 1 to 4As shown, this embodiment provides a portable underwater acoustic communication node device, including: a device body 1; and a portable component 2, including a connecting plate 21, a fixing ring 23, a rope 24, a fixing sleeve 25, and a rotating shaft 26. The connecting plate 21 is fixedly connected to the device body 1 by bolts. A connecting post is welded to the middle of the bottom of the connecting plate 21. The fixing ring 23 is welded to the bottom of the connecting post and its inner side contacts the wrist. The rope 24 is disposed on the outer side of the fixing ring 23 and is slidably connected to the fixing ring 23. The fixing sleeve 25 is fixedly connected to the bottom of the fixing ring 23. The two ends of the rope 24 penetrate the side wall of the fixing sleeve 25. The rotating shaft 26 is rotatably connected to the inside of the fixing sleeve 25 and is divided into upper and lower layers. The upper and lower layers of the rotating shaft 26 are respectively fixedly connected to the two ends of the rope 24.

[0033] The rope 24 can be made of nylon.

[0034] In addition, sealing rings are provided at the connection points of the rope 24, the rotating shaft 26 and the fixed sleeve 25.

[0035] Understandable Figure 1 The diagram only schematically illustrates some of the components included in the underwater acoustic communication node device. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, underwater acoustic communication node equipment can also include, compared to... Figure 1 More or fewer parts.

[0036] In this embodiment, the device body 1 and the portable component 2 constitute a portable underwater acoustic communication node device according to this application.

[0037] Example 2:

[0038] Specifically, the material of the retaining ring 23 is PE.

[0039] Specifically, the portable component 2 also includes a connecting plate 21, with both ends of the connecting plate 21 being fixedly connected to the connecting plate 21 and the fixing ring 23, respectively.

[0040] Specifically, the portable component 2 also includes a rotating handle 27, which is fixedly connected to the rotating shaft 26 and rotatably connected to the outside of the fixed sleeve 25, and has anti-slip texture on its side wall.

[0041] Specifically, multiple limiting plates are fixedly connected to the side wall of the fixing ring 23, and the rope 24 passes through the limiting plates and is slidably connected to the limiting plates.

[0042] In this embodiment, the connecting plate 21 increases the connection point between the connecting plate 21 and the fixing ring 23, restricts the position of the rope 24, enhances the structural stability of the portable component 2, prevents the fixing ring 23 from shaking, and the rotating handle 27 can drive the rotating shaft 26 to rotate. The anti-slip texture increases the friction of the hand, and the rope 24 slides along the inside of the limiting plate. The limiting plate restricts the position of the rope 24, prevents the rope 24 from deviating outside the fixing ring 23, and ensures the stability of the rope 24 when it is retracted or extended.

[0043] Example 3:

[0044] Specifically, a locking component 3 is provided on the side wall of the fixed sleeve 25.

[0045] Specifically, the locking assembly 3 includes: a control lever 31, rotatably connected to the mounting base, the mounting base being welded to the bottom of the inner wall of the fixed sleeve 25, with the other end extending out of the bottom of the fixed sleeve 25; a pawl 32, disposed inside the fixed sleeve 25 and fixedly connected to the control lever 31; a ratchet 33, fixedly connected to the bottom of the rotating shaft 26; and a torsion spring 34, with both ends fixedly connected to the side walls of the mounting base and the pawl 32, respectively.

[0046] In addition, a sealing ring is provided at the connection between the control lever 31 and the fixed sleeve 25.

[0047] In this embodiment, the torsion spring 34 pushes the pawl 32 to engage with the ratchet 33, restricting the rotation of the rotating shaft 26; the rotation control lever 31 can drive the pawl 32 to disengage from the ratchet 33, unlocking it, thereby locking and unlocking the rotating shaft 26 and ensuring the fixed state of the rope 24 after length adjustment.

[0048] In actual use, the user first puts their wrist through the retaining ring 23, and then rotates the handle 27. Rotating the handle 27 drives the rotating shaft 26 to rotate, which in turn drives the rope 24 to move and wrap around the rotating shaft 26. At this time, the rope 24 tightens, which in turn tightens the retaining ring 23, making the retaining ring 23 securely locked on the wrist. When unlocking is required, the control lever 31 is moved to disengage the pawl 32 from the ratchet 33. The retaining ring 23 returns to its original position under the action of elasticity, and the device can be removed. Then, the control lever 31 is released, and the control lever 31 rotates under the action of the torsion spring 34, causing the pawl 32 to re-engage on the ratchet 33 under the action of the torsion spring 34.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
