[0023] As Figures 1-4 The utility model discloses sliding groove buckle type angle spacing rotating shaft structure, including sliding groove structure piece 1, endless rotating shaft 2 and connecting plate 3.

[0024] The center of sliding groove structure piece 1 is fixed with square shaft 11, and the arc-shaped guide groove 12 around the center of square shaft 11 is arranged on the sliding groove structure piece 1, and the both ends of arc-shaped guide groove 12 are respectively provided with C-shaped plastic buckle 13, and the opening end of plastic buckle 13 faces the inside of arc-shaped guide groove 12. Among them, sliding groove structure piece 1, plastic buckle 13, arc-shaped guide groove 12 and square shaft 11 can be directly made on the rear cover 6 structure piece of display, also can be made into independent combination parts and lock fixed on the rear cover 6 of display. The position and direction of arc-shaped guide groove 12 and plastic buckle 13 can be adjusted to realize left, right rotation and the angle of rotation. The opening (size) of plastic buckle can be adjusted to realize the adjustment of the feeling strength.

[0025] The center of the endless rotating shaft 2 is connected with a rotating member 4, the center hole of the rotating member 4 is matched and sleeved on the square shaft 11, and the endless rotating shaft 2 can rotate around the square shaft 11.

[0026] The endless rotating shaft 2 is fixed on the connecting plate 3 by screw locking.

[0027] The connecting plate 3 is provided with a positioning column 31 corresponding to the arc-shaped guide groove 12, the positioning column 31 is in sliding connection with the arc-shaped guide groove 12 after penetrating through the hole position 21 on the side of the endless rotating shaft 2, and the diameter of the positioning column 31 is slightly larger than the opening size of the plastic buckle 13.

[0028] The utility model discloses still including the rotating shaft outer cover 5, the rotating shaft outer cover 5 surrounds the rotating shaft structure inside, and the rotating shaft outer cover 5 can adjust size and appearance according to specific product and make product more beautiful. As a kind of implementation, the sliding slot structure piece 1 is arranged on the rear cover 6 of display, and the connecting plate 3 and the rotating shaft outer cover 5 are fixed on the wall hanging piece 7 by screw locking.

[0029] The sliding slot structure piece 1 is provided with a gasket groove around the square shaft 11, the gasket groove is provided with a plastic gasket 8 sleeved on the square shaft 11, the plastic gasket 8 is distributed with lubricating hole, the lubricating hole is coated with lubricating paste, can make the endless rotating shaft 2 more smooth in the process of rotation.

[0030] The free end of the positioning column 31 is a spherical portion, which is in sliding connection with the arc-shaped guide groove 12.

[0031] The sliding slot structure piece 1 is provided with two symmetrically arranged arc-shaped guide grooves 12, and the connecting plate 3 is also provided with two corresponding positioning columns 31.

[0032] In the embodiment, the arc-shaped guide groove 12 can drive the endless rotating shaft 2 to rotate back and forth within a range of 90°, and the plastic buckles 13 at the two ends of the arc-shaped guide groove 12 are used for positioning the display in horizontal screen and vertical screen respectively.

[0033] The utility model utilizes the characteristics of elastic plastic deformation of the plastic buckle 13, realizes accurate positioning of the rotation angle and the feeling of over-point force through the interference fit design of the positioning column 31 and the plastic buckle 13. For example, when the display is rotated from horizontal screen to vertical screen to 90°, the positioning column 31 on the endless rotating shaft 2 is rotated to the opening position of the plastic buckle 13 at one end. Since the opening size of the plastic buckle 13 is smaller than the diameter of the positioning column 31, the positioning column 31 needs to overcome the deformation force of the plastic buckle 13 to enter the plastic buckle 13. The deformation force of the plastic buckle 13 is pulled and held by the positioning column 31, so that the accurate positioning of the rotation angle is ensured, and the feeling of over-point force is smooth.

[0034] Because the rotating shaft device is designed as a symmetrical structure, the double positioning columns 31 and the double sliding groove structure, the spherical part of the positioning column 31 contacts the bottom of the sliding groove, greatly improving the stability of the display screen during rotation, so that the display screen does not sway forward and backward during rotation. Similarly, when the display screen is rotated to horizontal screen use again, the positioning column 31 will support the plastic buckle 13 to slide into the arc-shaped guide groove 12 again, and the same rotation feeling is achieved. The point force is transmitted, and the display screen is stable at the 90° or 180° position, that is, the horizontal and vertical screen conversion can be realized.

[0035] The specific embodiments of the present application are described above, but those skilled in the art should understand that this is only an example, and those skilled in the art can make various changes or modifications to this embodiment without departing from the principles and essence of the present application. However, these changes and modifications all fall within the protection scope of the present application.
