(2) In some small spaces, it is even impossible to observe the instrument readings directly, which affects normal use. Utility Model Content

[0007] The aforementioned instrument plug rotating device has several sets of stopping grooves and sliding protrusions alternately arranged around its central axis on the outer peripheral surface of the plug panel, so that when the plug panel rotates, the spring glass ball performs elastic rolling motion along the movement trajectory on the stopping grooves and sliding protrusions to achieve anti-sliding.

Detailed Implementation

[0017] The present invention will be further described below through specific embodiments, so as to make the technical solution of the present invention easier to understand and master, rather than to limit the present invention.

[0018] Example: See Figures 1 to 3 This embodiment provides an instrument plug rotating device, which includes a rotating mounting mechanism, a plug mechanism 1, and a PCB mechanism; The rotating mounting mechanism includes an integrally formed limiting ring groove and a rotating through groove; The plug mechanism 1 includes a plug panel 11, a plug terminal assembly and a first PCB board 12, both mounted on the plug panel 11 and electrically connected. A limiting annular protrusion 13 is provided around the periphery of the plug panel 11. The limiting annular protrusion 13 is limited in the limiting annular groove. The plug panel 11 is rotatably disposed in the rotating through groove by an abutment assembly. A plurality of conductive rings 14 are arranged in concentric circles on the first PCB board 12. The PCB mechanism includes a second PCB board 21 and spring pins 22 that are electrically connected. Each spring pin 22 is in contact with a set of conductive rings 14 to conduct electricity, so as to realize the electrical connection between the second PCB board 21 and the plug terminal assembly.

[0019] Specifically, the plug mechanism 1 is innovatively mounted rotatably using the rotating mounting mechanism, allowing the plug mechanism 1 to maintain an electrical connection with the PCB mechanism without restriction of rotation. This solves the problem of existing instrument plugs lacking rotation functionality and being unable to read data in space-constrained situations. It also allows for adjustment of the instrument's viewing area position according to the actual reading position for easier reading. The plug panel 11 rotates within the rotating mounting mechanism under the action of the contact component, and the rotation is not limited by the rotation angle. As the plug panel 11 rotates, the spring pin 22 always rotates and slides on the conductive ring 14, ensuring a stable and uninterrupted electrical connection between the plug terminal assembly and the second PCB board 21. This avoids the problem of twisting and disconnection caused by the use of cable electrical connections in existing instrument plugs.

[0020] Preferably, a plurality of spring bead mounting slots are provided in the rotating through slot, and the abutting component is disposed in the spring bead mounting slot; The contact component includes a spring bead 15 disposed in the spring bead mounting groove. The spring bead 15 abuts against the outer peripheral surface of the plug panel 11, so that the spring bead 15 slides along the motion trajectory on its surface as the plug panel 11 rotates. Specifically, when the plug panel 11 is rotated, the spring bead 15 rotates synchronously on the outer peripheral surface of the plug panel 11 to form a motion trajectory.

[0021] Preferably, a plurality of sets of stopping grooves 16 and sliding protrusions 17 are alternately arranged around the central axis on the outer peripheral surface of the plug panel 11, so that when the plug panel 11 rotates, the spring glass ball 15 performs elastic rolling motion along the movement trajectory on the stopping grooves 16 and sliding protrusions 17 to achieve anti-sliding; specifically, the number of stopping grooves 16 and sliding protrusions 17 can be set according to actual use requirements to correspond to different rotation angles, so that the rotation mode of the plug panel 11 is not limited by the rotation angle, such as 90°, 180°, 270° or 360°, etc.

[0022] Specifically, when the plug panel 11 is rotated, the spring glass ball 15 slides along the sliding protrusion 17 and rolls into the stopping groove 16 under the elastic resistance of the spring glass ball 15, so as to realize the elastic rolling motion of the spring glass ball 15 along the motion trajectory and realize the precise adjustment of the viewing area position of the instrument.

[0023] Preferably, the plug panel 11 includes a first PCB receiving cavity, and the first PCB board 12 is mounted in the first PCB receiving cavity by a screw structure; A terminal mounting hole is provided through the plug panel 11 for the plug terminal assembly to pass through, and the terminal mounting hole is connected to the first PCB receiving cavity; specifically, the plug terminal assembly includes, but is not limited to, terminals such as live wire terminal, neutral wire terminal and ground terminal.

[0024] Specifically, the number of spring pins 22 is equal to the number of conductive rings 14, ensuring the electrical connection stability of the first PCB board 12 and the second PCB board 21.

[0025] In a preferred embodiment, the free rotation angle of the plug panel 11 is 0~360°, so that the rotation mode of the plug panel 11 is not limited by the rotation angle, such as 90°, 180°, 270° or 360°.

[0026] Specifically, the diameter of the limiting ring groove is larger than the diameter of the rotating through groove to prevent the plug panel 11 from falling off during rotation, thereby improving the rotational stability and reliability of the plug panel 11.

[0027] This embodiment also discloses an instrument, which includes the aforementioned instrument plug rotation device; specifically, the instrument includes, but is not limited to, a multimeter or other instruments with reading functions.

[0028] When this utility model is in operation, it includes the following steps: (1) The tester inserts the plug terminal assembly into the socket; (2) The tester rotates the instrument according to his position so that the viewing area of ​​the instrument faces the tester; When the instrument is rotated, the spring glass ball 15 slides along the sliding protrusion 17 and rolls into the stopping groove 16 under the elastic resistance of the spring glass ball 15, so that the spring glass ball 15 can perform elastic rolling motion along the movement trajectory. Continue to rotate the instrument until the viewing area of ​​the instrument is adjusted to face the tester, so as to accurately adjust the viewing area position of the instrument.

[0029] This utility model features a reasonable and ingenious design. It innovatively uses a rotating mounting mechanism to rotatably mount the plug mechanism, ensuring that the plug mechanism maintains an electrical connection with the PCB mechanism without restriction during rotation. This solves the problem of existing instrument plugs lacking rotation functionality and being unable to provide readings in space-constrained situations. It allows for adjustment of the instrument's viewing area position based on the actual reading location for easier reading. The plug panel rotates within the rotating mounting mechanism under the contact of the contact component, and the rotation is not limited by the rotation angle. Furthermore, as the plug panel rotates, the spring pin continuously rotates and slides on the conductive ring, ensuring a stable and uninterrupted electrical connection between the plug terminal assembly and the second PCB board. This avoids the problem of twisting and disconnection that occurs with existing instrument plugs using cable electrical connections.
