[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: a voice recorder with a waterproof and dustproof structure, the voice recorder body 1 includes a base 1.1 and a cylindrical voice recorder body 1.2 whose bottom end is fixed to the top surface of the base 1.1, the front wall of the cylindrical voice recorder body 1.2 is provided with a cut surface 1.2.1, and the cut surface 1.2.1 is provided with a display screen, buttons and sound pickup holes; wherein, the audio acquisition module and related control modules of the voice recorder are all integrated in the cylindrical voice recorder body 1.2, the base 1.1 is used to hold the battery, and the battery charging port is also provided on the cut surface, that is, the holes and other structures involved in the voice recorder are all provided on the cut surface 1.2.1. A cylinder 1.3 is fixed in the middle of the top surface of the cylindrical voice recorder body 1.2, and a prism 1.4 is fixedly connected to the top of the cylinder 1.3; an annular groove 1.2.2 is provided at the bottom end of the outer peripheral wall of the cylindrical voice recorder body 1.2.

[0023] The rotating housing 2 is rotatably mounted on the outside of the cylindrical recording body 1.2. The side wall of the rotating housing 2 is provided with a window 2.1 corresponding to the cut surface 1.2.1. A positioning groove 2.3 is provided near the outer edge of the top surface of the rotating housing 2. A sleeve hole 2.2 is provided in the middle of the top surface of the rotating housing 2 to be rotatably mounted on the cylinder 1.3. An annular protrusion 2.4 is provided at the bottom end of the inner peripheral wall of the rotating housing 2 to be rotatably engaged with the annular groove 1.2.2.

[0024] The top cover 3 includes a round cover 3.1, a positioning pin 3.2, an elastic member 3.3 and a plug 3.4. The slot 3.1.1 is arranged at the center of the bottom surface of the round cover 3.1. The top surface of the round cover 3.1 is provided with a column cavity 3.1.2 at the positions corresponding to the front and rear sides of the slot 3.1.1. The bottom center of the column cavity 3.1.2 is provided with a through hole 3.1.3 that matches the bottom of the positioning pin 3.2. The elastic member 3.3 is arranged in the column cavity 3.1.2 and the bottom end is pressed against the top surface of the positioning pin 3.2. The plug 3.4 is sleeved on the top of the column cavity 3.1.2 and the bottom surface is pressed against the top of the elastic member 3.3. Among them, the slot 3.1.1 is fixedly sleeved with the prism 1.4. The positioning pin 3.2 is a T-shaped structure.

[0025] In summary, when the voice recorder needs to be used, the rotating shell 2 is rotated 180°. At this time, the positioning groove 2.3 is rotated to a position corresponding to the front positioning pin 3.2. Under the action of the elastic member 3.3, the bottom end of the positioning pin 3.2 is inserted into the positioning groove 2.3 to facilitate the positioning of the rotating shell 2; at the same time, the window 2.1 is opposite to the section 1.2.1, so that the display screen, buttons, pickup hole and charging hole of the cylindrical recording body 1.2 are exposed for easy operation.

[0026] When the recording pen is idle, the rotating shell 2 is rotated 180° again so that the window 2.1 is directly opposite to the middle of the rear wall of the cylindrical recording body 1.2. At this time, the positioning groove 2.3 is directly opposite to the positioning pin 3.2 at the rear. At this time, the holes involved in the recording pen are sealed in the rotating shell 2, achieving the effect of waterproof and dustproof.

[0027] The positioning groove 2.3 is a conical groove, and the bottom end of the positioning pin 3.2 is a spherical convex structure. This is because when the rotating housing 2 is positioned, only a small stagnation pressure needs to be provided; and this structure facilitates the rotation of the rotating housing 2 when the rotating housing 2 is rotated with force, and the conical inclined surface of the positioning groove 2.3 can compress the elastic member 3.3 upward through the spherical convex structure to move the positioning pin 3.2 upward, so that the rotating housing 2 can be rotated.

[0028] In order to facilitate the disassembly and assembly of the plug 3.4, the top of the column cavity 3.1.2 is provided with an internal thread 3.1.4 that matches the threaded sleeve of the plug 3.4, and a regular hexagonal groove is provided in the center of the top surface of the plug 3.4.
