The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] The first embodiment of the present application is:

[0022] See also Figure 1 to Figure 4 ,in Figure 1 It is a structural schematic diagram of the first embodiment of the utility model. Figure 2 It is a three-dimensional diagram of the first embodiment of the utility model. Figure 3 It is a partial structural schematic diagram of the first embodiment of the utility model. Figure 4 It is a partial structural schematic diagram of the first embodiment of the utility model.

[0023] The utility model provides a clamping mechanism for a rotating shaft of a notebook computer, comprising a mounting plate 101 and a clamping unit, wherein the clamping unit comprises a fixing plate 103, a circular shaft 104, two limiting rings 105, a sleeve 106, a connecting plate 107, a disc 109, a spring 111, a fixing disc 112, a holding assembly, an adjusting assembly and a guiding assembly, wherein the holding assembly comprises a holding disc 113 and a plurality of arc blocks 114, the adjusting assembly comprises a gasket 115 and a nut 116, and the guiding assembly comprises two guiding blocks 117 and a sliding rod 118. The above-mentioned scheme solves the problem in the prior art that the clamping structure is not convenient for adjusting the pressure on the rotating shaft, which easily causes the rotating shaft to be too loose or too tight, thereby affecting the rotation between the main body of the notebook computer and the display screen.

[0024] According to the present specific embodiment, the fixing plate 103 is fixedly connected to the mounting plate 101 and is located on the upper surface of the mounting plate 101. The circular shaft 104 penetrates the fixing plate 103 and is rotatably connected to the fixing plate 103. The two limiting rings 105 are both sleeved on the outside of the circular shaft 104 and are respectively located on both sides of the fixing plate 103. The sleeve 106 is sleeved on the outside of the circular shaft 104 and is rotatably connected to the circular shaft 104. The connecting plate 107 is fixedly connected to the sleeve 106 and is located on the outside of the sleeve 106. The abutting assembly is arranged at one end of the sleeve 106. The circular disc 109 and the fixing disc 112 are both sleeved on the outside of the circular shaft 104. The spring 111 is arranged between the circular disc 109 and the fixing disc 112. One end of the spring 111 is fixedly connected to the circular disc 109, and the other end of the spring 111 is fixedly connected to the fixing disc 112. The guide component guides the disc 109 and the fixed disc 112, and the adjustment component is arranged on one side of the fixed disc 112. When in use, the mounting plate 101 is connected to the computer body, and the connecting plate 107 is connected to the display screen. When the display screen is rotated, the connecting plate 107 drives the sleeve 106 to rotate, and the sleeve 106 drives the supporting component to rotate. The supporting component supports the movement of the disc 109, and the disc 109 supports the spring 111 to contract. At the same time, under the elastic potential energy of the spring 111, the disc 109 will resist the supporting component, so that when no external force is used to rotate the display screen, the connecting plate 107 will not drive the sleeve 106 to rotate, thereby fixing the angle between the display screen and the computer body, and the elasticity of the spring 111 can be adjusted by the adjustment component, thereby adjusting the friction between the disc 109 and the supporting component.

[0025] Among them, the supporting plate 113 is fixedly connected to the sleeve 106 and is located at one end of the sleeve 106. The disc 109 has a plurality of grooves 110 adapted to the arc block 114. One ends of the plurality of arc blocks 114 are respectively fixedly connected to the supporting plate 113, and the other ends of the plurality of arc blocks 114 are respectively inserted into the corresponding grooves 110. When in specific use, when the sleeve 106 drives the supporting plate 113 to rotate, the supporting plate 113 drives the arc block 114 to rotate, so that the arc block 114 leaves the groove 110 and resists the disc 109. The disc 109 resists the spring 111 to contract. When the arc block 114 moves to the next groove 110, the spring 111 rebounds, so that the disc 109 resists the arc block 114.

[0026] Secondly, the gasket 115 is sleeved on the outer side of the round shaft 104 and fits with the fixed plate 112. The nut 116 is sleeved on the outer side of the round shaft 104 and is threadedly connected with the round shaft 104. When in use, the nut 116 is screwed, and the nut 116 pushes the gasket 115 to move on the round shaft 104. The gasket 115 drives the fixed plate 112 to move, and the fixed plate 112 pushes the spring 111 to move.

[0027] At the same time, the two guide blocks 117 are fixedly connected to the disc 109 and the fixed disc 112 respectively, one end of the slide rod 118 is fixedly connected to the fixed plate 103, and the other end of the slide rod 118 passes through the two guide blocks 117 respectively and is slidably connected to the two guide blocks 117 respectively. When in specific use, the fixed disc 112 and the disc 109 will drive the two guide blocks 117 to slide on the slide rod 118 when moving, thereby guiding the fixed disc 112 and the disc 109.

[0028] In addition, the mounting plate 101 has a plurality of first mounting holes 102, and the connecting plate 107 has two second mounting holes 108. When in actual use, the first mounting holes 102 are provided to facilitate connection of the mounting plate 101 to the computer body, and the second mounting holes 108 are provided to facilitate connection of the connecting plate 107 to the display screen.

[0029] When using the clamping mechanism of the laptop computer shaft of the present embodiment, the mounting plate 101 is connected to the computer body, and the connecting plate 107 is connected to the display screen. When the display screen is rotated, the connecting plate 107 drives the sleeve 106 to rotate, and the sleeve 106 drives the abutting plate 113 to rotate, and the abutting plate 113 drives the arc block 114 to rotate, so that the arc block 114 moves away from the groove 110 and abuts the disc 109 to move, and the disc 109 abuts the spring 111 to contract. When the arc block 114 rotates to the next groove 110, the disc 109 will press against the spring 111 under the elastic potential energy of the spring 111. The arc block 114 is held in the groove 110, so that when the display screen is rotated without external force, the connecting plate 107 will not drive the sleeve 106 to rotate, thereby fixing the angle between the display screen and the computer body. The elasticity of the spring 111 can be adjusted by screwing the nut 116, thereby adjusting the friction between the disk 109 and the arc block 114, thereby adjusting the tightness between the display screen and the computer body. This method can effectively solve the problem in the prior art that the clamping structure is not convenient for adjusting the pressure on the shaft, which easily causes the shaft to be too loose or too tight, thereby affecting the rotation between the laptop body and the display screen.

[0032] The utility model provides a clamping mechanism for a rotating shaft of a notebook computer, which also includes two groups of limiting components. Each group of the limiting components includes two vertical plates 201 and a limiting plate 202 .

[0033] According to this specific embodiment, the two groups of the limiting components are symmetrically arranged on the upper surface of the mounting plate 101, one end of the two vertical plates 201 are respectively fixedly connected to the mounting plate 101, and the other ends of the two vertical plates 201 are respectively fixedly connected to the limiting plates 202. When in specific use, the two vertical plates 201 are used to fix the limiting plates 202, and the rotation angle of the connecting plate 107 is limited by the limiting plates 202.

[0034] When using the clamping mechanism of the laptop computer shaft according to this embodiment, the two vertical plates 201 are used to fix the limiting plate 202, and the rotation angle of the connecting plate 107 is limited by the limiting plate 202, so that the rotation angle of the connecting plate 107 is between 0 and 180 degrees.
