[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Please refer to Figures 1-9, the present invention provides a technical solution: a notebook housing that can prevent the connection line from falling off, including a notebook housing base 1 and a notebook housing upper cover 5. The connection between the notebook housing base 1 and the notebook housing upper cover 5 is rotatably connected through a damping rotating shaft. A power interface reserved hole 6 is provided on the inner wall of the notebook housing base 1. Anti-dropping mechanisms 2 are provided on both sides of the notebook housing base 1. Reinforcement mechanisms 3 are provided on both sides of the notebook housing base 1. Cable bundling mechanisms 4 are provided on both sides of the notebook housing base 1; the anti-dropping mechanism 2 includes protective shells 201. The number of protective shells 201 is four. The side of the protective shell 201 close to the notebook housing base 1 is fixedly connected to the notebook housing base 1. The anti-dropping mechanism 2 is used to prevent the USB connection line from falling off; the reinforcement mechanism 3 includes support plates 302. The number of support plates 302 is four. The side of the support plate 302 close to the notebook housing base 1 is fixedly connected to the notebook housing base 1. The reinforcement mechanism 3 is used to further fix the USB connection line; the cable bundling mechanism 4 includes first cable bundling shells 401. The number of first cable bundling shells 401 is two. The two first cable bundling shells 401 are respectively arranged on both sides of the notebook housing base 1. The cable bundling mechanism 4 is used to bundle the USB connection line.

[0022] As a further limitation of the anti-dropping mechanism 2 of the present invention, installation grooves 7 are provided between the opposite sides of the protective shell 201. A connecting pipe 207 is fixedly connected between the inner walls of the two installation grooves 7. A friction ring 206 is fixedly connected to the inner wall of the connecting pipe 207. A push rod 202 is slidably connected to the inner wall of the friction ring 206. One end of the push rod 202 is fixedly connected to an extrusion plate 208. The other end of the push rod 202 is fixedly connected to a push-pull plate 203; through the cooperation of the installation groove 7, the connecting pipe 207, the friction ring 206, the push rod 202, the extrusion plate 208, the push rod 202 and the push-pull plate 203, the USB interface can be fixed, thereby increasing the stability and firmness of the USB interface during use.

[0023] Rotating blocks 204 are rotatably connected to the inner walls of the protective shells 201. First friction pads 205 are fixedly connected to the opposite sides of the two rotating blocks 204. The first friction pads 205 are made of rubber material. The rotating blocks 204 are used in cooperation with the extrusion plate 208; through the cooperation of the rotating blocks 204 and the first friction pads 205, the stability and firmness of the USB interface during fixation can be further increased. By setting the first friction pads 205 to be made of rubber material, the friction force between the first friction pads 205 and the USB interface after contact can be increased, thereby increasing the stability and firmness of the USB interface after connection.

[0024] The top and bottom of the rotating block 204 are fixedly connected with first rotating rods 10. The opposite ends of the two first rotating rods 10 penetrate through the inner wall of the protective shell 201 and are rotatably connected with the inner wall of the protective shell 201. Through the first rotating rods 10, the rotating block 204 can rotate, and at the same time, the stability of the rotating block 204 during rotation can be ensured, avoiding the deviation of the rotating block 204 during rotation, thereby avoiding affecting the normal rotation of the rotating block 204 and enabling the rotating block 204 to work.

[0025] By providing the anti-detachment mechanism 2, under the action of the anti-detachment mechanism 2, it is convenient for the user not to separate the USB interface from the externally connected peripheral device when using the assembled notebook computer. When the USB interface of the peripheral device is affected by an external force, the connectivity between the USB interface of the peripheral device and the notebook computer can be increased, making the connection more secure, avoiding detachment, and thus avoiding affecting the normal use of the peripheral device by the user.

[0026] The specific implementation of this embodiment is as follows: In order to increase the stability and firmness of the connection between the USB interface of the peripheral device and the notebook computer, the user first inserts the USB interface of the peripheral device into the protective shell 201 and connects it to the assembled notebook computer. Then, the user pushes the push-pull plate 203 to drive the push rod 202 to move in the connecting pipe 207. The moving push rod 202 drives the pressing plate 208 to move until the pressing plate 208 contacts the rotating block 204. When the pressing plate 208 contacts the rotating block 204, the rotating block 204 rotates, driving the first rotating rod 10 to rotate. When the rotating block 204 rotates, the position of the first friction pad 205 changes. After the position of the first friction pad 205 changes, it contacts the USB socket of the peripheral device. Under the continuous movement of the pressing plate 208, the first friction pad 205 closely fits with the USB socket, thereby increasing the connection effect between the USB socket and the assembled notebook computer. At the same time, under the action of the friction ring 206, the friction between the push rod 202 and the connecting pipe 207 is increased, avoiding the situation where the push rod 202 moves under the influence of an external force.

[0027] Embodiment 2: Please refer to Figures 1-9 , the present invention provides a technical solution: a notebook shell that can avoid the detachment of the connecting line. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0028] As a further limitation of the reinforcement mechanism 3 of the present invention, two mounting plates 305 are fixedly connected to both sides of the base 1 of the notebook housing. A knob 301 is rotatably connected to the inner wall of the mounting plate 305 through a bearing. One end of the knob 301 is fixedly connected to a transmission gear 303. A semi-circular gear 306 is meshed with the surface of the transmission gear 303. A second friction pad 304 is fixedly connected to one side of the semi-circular gear 306. The second friction pad 304 is made of rubber material. Second rotating rods 8 are fixedly connected to both the top and bottom of the semi-circular gear 306. Opposite ends of the two second rotating rods 8 penetrate through the inner wall of the protective shell 201 and are rotatably connected to the inner wall of the protective shell 201; A connection frame 307 is fixedly connected to the top of the support plate 302. A clamping sleeve 311 is movably connected to the inner wall of the connection frame 307. One end of the clamping sleeve 311 is fixedly connected to a sliding rod 309. One end of the sliding rod 309 penetrates through the outside of the connection frame 307 and is fixedly connected to a limiting tooth plate 308. The surface of the limiting tooth plate 308 is meshed with the surface of the transmission gear 303. A first spring 310 is fixedly connected to the inner wall of the clamping sleeve 311. The other end of the first spring 310 is fixedly connected to the inner wall of the connection frame 307; By setting the connection frame 307, the clamping sleeve 311, the sliding rod 309, the limiting tooth plate 308 and the first spring 310 to cooperate, the transmission gear 303 can be limited, so that the transmission gear 303 will not rotate due to external forces.

[0029] A push-pull rod 9 is fixedly connected to the top of the clamping sleeve 311. Guide blocks 16 are fixedly connected to both sides of the clamping sleeve 311. The surface of the guide block 16 is slidably connected to the inner wall of the connection frame 307; By setting the cooperation of the push-pull rod 9 and the guide block 16, it is convenient for the user to move the clamping sleeve 311, so as to conveniently limit the transmission gear 303 for the user.

[0030] By setting the reinforcement mechanism 3, under the action of the reinforcement mechanism 3, the stability and firmness of the USB interface of the peripheral device after being inserted into the notebook computer are further increased, so that both sides of the USB interface are subjected to pressure, so that the connection between the USB interface and the notebook computer is more stable and firm, achieving the purpose of further increasing the stability and firmness of the USB interface when inserted into the notebook computer.

[0031] The specific implementation of this embodiment is as follows: In order to further increase the stability and firmness when the USB interface of the peripheral device is connected to the assembled laptop, the user first moves the push rod 9 to drive the clamping sleeve 311 to move. The moving clamping sleeve 311 drives the guiding block 16 to slide in the connecting frame 307. While moving, the clamping sleeve 311 squeezes the first spring 310, causing the first spring 310 to deform under force. While moving, the clamping sleeve 311 drives the sliding rod 309 to move, thereby driving the separation of the contact between the limiting tooth plate 308 and the transmission gear 303. At this time, the user rotates the knob 301 to drive the transmission gear 303 to move. The rotating transmission gear 303 drives the semi-circular gear 306 to rotate. The rotating semi-circular gear 306 drives the second friction pad 304 to rotate, causing the angle of the rotated second friction pad 304 to change. When the second friction pad 304 rotates to contact the USB interface of the peripheral device, through the extrusion of the second friction pad 304, the USB interface of the peripheral device is tightly fixed in the protective shell 201. At this time, the user releases the push rod 9. Under the push of the first spring 310 against gravity, the sliding rod 309 drives the limiting tooth plate 308 to mesh with the transmission gear 303 again, making the transmission gear 303 unable to rotate, thereby further increasing the stability and firmness of the USB interface of the peripheral device in the protective shell 201.

[0032] Embodiment 3: Please refer to Figures 1-9 , the present invention provides a technical solution: a laptop shell that can prevent the connection line from falling off. The present invention makes corresponding improvements to the technical problems mentioned in the background art.

[0033] As a further limitation of the wire bundling mechanism 4 of the present invention, second wire bundling shells 403 are provided on both sides of the first wire bundling shell 401. Connecting columns 405 are fixedly connected to the same side of the first wire bundling shell 401 and the second wire bundling shells 403. The sides of the connecting columns 405 close to the base 1 of the notebook housing are fixedly connected to the base 1 of the notebook housing. An arc-shaped baffle 402 is rotatably connected between the inner walls of the first wire bundling shell 401 and the second wire bundling shells 403. A semi-circular ring 404 is fixedly connected to the surface of the arc-shaped baffle 402. The number of semi-circular rings 404 is two. A fixed block 13 is fixedly connected to the top of the second wire bundling shell 403. Push-pull blocks 12 are fixedly connected to the tops of the two semi-circular rings 404. A connecting rod 11 is fixedly connected between the opposite sides of the two push-pull blocks 12. A clamping rod 15 is fixedly connected to one side of the push-pull block 12. One end of the clamping rod 15 extends into the inner wall of the fixed block 13 and is in close contact with the inner wall of the fixed block 13. A clamping plate 14 is fixedly connected to one side of the fixed block 13. The number of clamping plates 14 is two. The opposite sides of the two clamping plates 14 are in close contact with the surface of the clamping rod 15; a second spring 407 is fixedly connected to one side of the semi-circular ring 404. One end of the second spring 407 is fixedly connected to one side of the base 1 of the notebook housing. A protective sleeve 406 is movably sleeved on the surface of the second spring 407. The protective sleeve 406 is made of silica gel material; by setting the combined use of the second spring 407 and the protective sleeve 406, it is convenient for the user to reset when moving the semi-circular ring 404, so as to facilitate the user to put the USB connection cord into the first wire bundling shell 401 and the second wire bundling shells 403 for bundling. By setting the protective sleeve 406 to be made of silica gel material, the protective sleeve 406 can be made plastic, so that it can change following the change of the second spring 407 after being stressed.

[0034] By providing the wire bundling mechanism 4, under the action of the wire bundling mechanism 4, it is convenient for the user to bundle the connection wires of the peripheral devices when using the peripheral devices, and avoid the situation that the connection wires of the peripheral devices are messy during use. When such a messy situation occurs, the user is likely to involve the connection wires when using the notebook computer, resulting in the separation of the USB connection wire interface from the notebook computer, achieving the purpose of bundling the connection wires of the peripheral devices.

[0035] The specific implementation of this embodiment is as follows: To facilitate the user in binding and tidying up the connecting wires of peripheral devices, the user first moves the connecting rod 11 to drive the push-pull block 12 to move. The movement drives the semi-circular ring 404 to drive the arc-shaped baffle 402 to rotate. The arc-shaped baffle 402 is rotated to 180 degrees. While the semi-circular ring 404 is moving, it drives the second spring 407 to move, causing the second spring 407 to deform under the extrusion of the semi-circular ring 404. At this time, the user puts the connecting wire of the peripheral device into the first wire bundling shell 401. Subsequently, the user releases the connecting rod 11. At this time, the arc-shaped baffle 402 returns to its original position under the action of the counter-gravity of the second spring 407, and the power cord of the peripheral device can be bound between the arc-shaped baffle 402 and the first wire bundling shell 401.
