DETAILED DESCRIPTION

[0019] 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.

[0020] Embodiment 1:

[0021] Please refer to Figure 1-Figure 4 The utility model provides a technical solution: a notebook computer shaft comprises a display screen connection sleeve 1 and two host connection sleeves 2. The display screen connection sleeve 1 is arranged between the two host connection sleeves 2. Positioning cylinders 3 are movably arranged on the inner surfaces of the left and right sides of the display screen connection strip. Through grooves 4 are provided on the outer surfaces of the two positioning cylinders 3 near the host connection sleeve 2. Positioning rods 6 are fixedly connected inside the through grooves 4. The inner surfaces of the two host connection sleeves 2 near the display screen connection sleeve 1 are fixedly connected with first springs 5. The other end of the first spring 5 is movably fitted with the inner wall of the through groove 4. Threaded holes are provided on the outer surfaces of the positioning cylinder 3 and the host connection sleeve 2. Flat-head cross screws 7 are threadedly connected to the corresponding threaded holes of the positioning cylinder 3 and the host connection sleeve 2. In this embodiment, when the display screen and the host need to be disassembled, the flat-head cross screws 7 on both sides are first unscrewed to release the limit of the positioning cylinder 3, so that the positioning cylinder 3 is driven to move under the reset force of the first spring 5, and then the positioning cylinder 3 is moved so that the positioning cylinder 3 is separated from the host connection sleeve 2.

[0022] The inner surface of the display screen connecting sleeve 1 is rotatably connected to two rotating disks 8, and the outer surfaces of the two rotating disks 8 facing away from each other are fixedly connected to a second spring 9. The other end of the second spring 9 is fixedly connected to the outer surface of the positioning cylinder 3, and the outer surfaces of the two positioning cylinders 3 are fixedly connected to a lever 12. In this embodiment, the lever 12 is pushed to compress the second spring 9 until the positioning cylinder 3 is detached from the inside of the host connecting sleeve 2.

[0023] A plurality of heat dissipation holes 10 are provided on the outer surface of the host connection sleeve 2, and a dustproof net 11 is provided on the outer side of the heat dissipation holes 10. In this embodiment, the heat dissipation holes 10 are provided to facilitate heat discharge, and the dustproof net 11 is provided to reduce dust from entering the display screen connection sleeve 1 through the heat dissipation holes 10.

[0024] Two slide grooves 13 are provided on the rear outer surface of the display screen connecting sleeve 1, and the two levers 12 are respectively slidably connected to the inside of the two slide grooves 13. In this embodiment, when the lever 12 moves, it slides inside the slide groove 13, and the slide groove 13 provides the required channel for the movement of the lever 12.

[0025] One end of the two positioning cylinders 3 located inside the display screen connecting sleeve 1 is fixedly connected to the limiting rod, and the two limiting rods are movable through the rotating disk 8. The two second springs 9 are respectively mounted on the outer surfaces of the two limiting rods. In this embodiment, the second springs 9 are limited by the limiting rod. When the positioning cylinder 3 moves, the limiting rod slides inside the rotating disk 8 and prevents the second springs 9 from tilting and deforming.

[0026] The length of the slide groove 13 is greater than the distance between the positioning rod 6 and the side of the host connecting sleeve 2 away from the flat head cross screw 7. In this embodiment, the above technical solution is adopted to prevent the positioning rod 6 and the positioning tube 3 from being separated from the inside of the host connecting sleeve 2 when the lever 12 slides in the slide groove 13.

[0027] Working principle: When the utility model is in use, the display screen is fixed on the display screen connecting sleeve 1, and the host connecting sleeve 2 is fixed on the host. When the display screen and the host need to be disassembled, first unscrew the flat head cross screws 7 on both sides to release the limit of the positioning cylinder 3, thereby driving the positioning cylinder 3 to move under the reset force of the first spring 5. After the positioning cylinder 3 moves to a certain position, the maintenance personnel pushes the lever 12 in the direction of approaching each other, and the lever 12 drives the positioning cylinder 3 to move, so that the second spring 9 is compressed until the positioning cylinder 3 is detached from the inside of the host connecting sleeve 2, and then the positioning cylinder 3 on the other side is detached from the host connecting sleeve 2 on the other side, thereby disassembling and separating the display screen and the host.

[0028] When the laptop is in use, the hinge of the laptop is usually located at the heat dissipation port at the rear of the laptop. The obstruction of the hinge affects the heat dissipation function of the laptop. The heat dissipation hole 10 is provided to facilitate heat discharge, and the dustproof net 11 is provided to reduce dust from entering the display connection sleeve 1 through the heat dissipation hole 10.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
