Description

Technical Field

[0001] The utility model relates to the technical field of connection devices, in particular to a simple connection device for a computer and external equipment. Background Art

[0002] Computer, commonly known as computer, is a modern electronic computing machine used for high-speed calculation. It can perform numerical calculations, logical calculations, and has storage memory functions. Generally, computers are equipped with sockets to facilitate people to transmit data, but due to the limited number of data sockets on computers, it cannot meet people's usage needs. At this time, USB extenders appear to realize connection with external devices.

[0003] The existing simple connection device between a computer and an external device refers to patent document CN210040687U, and the device proposed in the patent document can prevent external dust from entering the USB data plug.

If the length of the line is too long, it will drag on the ground, which is easy to be entangled with other lines of the computer. If the length is too short, it will affect the convenience of use. For this reason, we provide a simple connection device between the computer and external devices to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] As described in the background art, in order to solve the problem of fixed length of the connecting wire, this embodiment provides a simple connecting device between a computer and an external device, which can flexibly adjust the length of the wire to facilitate connection with the external device.

[0026] See also Figures 1 to 5 This embodiment proposes a simple connection device for a computer and an external device, including a shell 1, a suction cup 6 is installed on the bottom surface of the shell 1, and the diameter of the suction cup 6 is smaller than the diameter of the shell 1. By setting the suction cup 6, the device can be adsorbed at a suitable position on the desktop for easy use.

[0027] The inner top wall of the housing 1 is rotatably connected to the USB extender body 2. The outer surface of the USB extender body 2 is provided with evenly distributed USB sockets 3. Each USB socket 3 is electrically connected to the USB extender body 2. The USB extender body 2 and the USB sockets 3 are both existing structures, and the internal structures and working principles of the USB extender body 2 and the USB sockets 3 are not described in detail herein.

[0028] A dustproof mechanism 4 is provided on the outside of each USB socket 3. The dustproof mechanism 4 includes a fixing plate 401 and a bottom plate 402 fixedly connected to the outer surface of the shell 1. The fixing plate 401 is located above the bottom plate 402. A connecting rod 403 is provided on the inner wall sliding sleeve of the fixing plate 401. A dustproof plate 406 is fixedly connected to the bottom surface of the connecting rod 403.

[0029] When the connecting rod 403 moves upward, the dustproof plate 406 can be driven to move upward, thereby exposing the corresponding USB port 3 to the outside, making it easier to connect the external device to the USB port 3, and facilitating the connection between the computer and the external device through the device.

[0030] The size of the dustproof plate 406 is greater than the size of the USB socket 3. The dustproof plate 406 can be provided to prevent dust from entering the USB socket 3 when not in use.

[0031] The top end of the connecting rod 403 is fixedly connected with a shift block 404 , the bottom end of the shift block 404 is fixedly connected with a telescopic spring 405 , the bottom end of the telescopic spring 405 is fixedly connected to the upper surface of the fixed plate 401 , and the telescopic spring 405 is sleeved on the outside of the connecting rod 403 .

[0032] When the telescopic spring 405 is deformed, elastic force is generated. When the shift block 404 is pulled upward, the connecting rod 403 drives the dustproof plate 406 to move upward, so that the telescopic spring 405 is in a stretched state, causing the telescopic spring 405 to deform and generate elastic force.

[0033] Then, the wire of the external device is inserted into the USB socket 3, and the pulled block 404 is released at the same time, and the dustproof plate 406 will move downward with the elastic force of the telescopic spring 405, thereby elastically clamping the wire end inserted into the USB socket 3. Figure 3 shown.

[0034] By providing the telescopic spring 405, the dustproof plate 406 can be easily reset, and the external port can also be limited, thereby improving the plugging stability between the external port and the USB socket 3, and facilitating a more convenient connection between the computer and the external device.

[0035] An adjustment mechanism 5 is provided inside the housing 1, and the adjustment mechanism 5 includes a rotating rod 501 rotatably connected to the inner bottom wall of the housing 1, the top of the rotating rod 501 is fixedly connected to the bottom surface of the USB extender body 2, and the outer surface of the rotating rod 501 is fixedly connected to a wire storage disk 502. When the rotating rod 501 rotates, the wire storage disk 502 and the USB extender body 2 will be driven to move together.

[0036] A connecting wire 503 is installed at the bottom of the USB extender body 2. Figure 1 and Figure 5 As shown, one end of the connecting wire 503 away from the USB extender body 2 extends to the outside of the housing 1 through the wire hole on the surface of the housing 1 , and the connecting wire 503 is wound around the outside of the wire storage tray 502 .

[0037] By limiting the relationship between the connecting wire 503 and the wire storage disk 502 , when the wire storage disk 502 rotates, the connecting wire 503 can be driven to move, thereby facilitating the control of the extension and retraction of the connecting wire 503 .

[0038] A USB plug 504 and a Type-C plug 505 are installed at one end of the connecting wire 503. By providing the USB plug 504 and the Type-C plug 505, the flexibility of the external device can be improved and it is more practical.

[0039] A worm gear 506 is fixedly connected to the outer surface of the rotating rod 501, and a worm 507 meshing with the worm gear 506 is installed on the inner bottom wall of the outer shell 1. By arranging the worm gear 506 and the worm gear 507 to cooperate with each other, the rotating rod 501 can have the effect of deceleration and self-locking. If the rotating rod 501 and the wire storage drum 502 are to be rotated, it can only be achieved by rotating the worm gear 507.

[0040] In this way, when the worm 507 is rotated, the wire storage disk 502 can be driven to rotate, thereby controlling the winding and unwinding of the connecting wire 503, so that the staff can extend the connecting wire 503 to a suitable length, facilitating the convenient connection between the computer and external devices.

[0041] Both shaft ends of the worm 507 penetrate the housing 1 and extend to the outside of the housing 1. Both shaft ends of the worm 507 are fixedly connected with handles 508. By providing the handles 508, the contact area of ​​the worm 507 can be increased, making it easier to rotate the worm 507.

[0042] Working principle: When in use, the USB plug 504 or the Type-C plug 505 can be used to connect to the computer body, and then the handle 508 can be turned to control the length of the connecting wire 503. When the handle 508 is turned, the worm 507 can be driven to rotate. When the worm 507 is turned, the rotating rod 501 can be driven to rotate through the meshing worm gear 506. When the rotating rod 501 is turned, the storage tray 502 and the USB extender body 2 can be rotated together. When the storage tray 502 is turned, the connecting wire 503 wound on its surface can be rotated, and then the connecting wire 503 exposed outside the shell 1 can be pulled. In this way, the length of the connecting wire 503 exposed outside can be increased. If it is found that the exposed length of the connecting wire 503 is too long, the handle 508 can be turned in the opposite direction to drive the storage tray 502 to reverse. The connecting wire 503 is retracted, and then the exposed length of the connecting wire 503 is adjusted to an appropriate value. The device is adsorbed on the desktop through the suction cup 6 installed on the bottom surface of the shell 1, and the USB socket 3 at a suitable position is selected, and the port of the external device is plugged into the USB socket 3. In this process, it is necessary to pull upward the corresponding dial block 404 on the outside of the USB socket 3 to move the connecting rod 403 and the dustproof plate 406 upward. When the connecting rod 403 moves upward, the telescopic spring 405 will be stretched to generate elastic force, and then the port of the external device is plugged into the USB socket 3. Finally, the pulled dial block 404 is released. At this time, the dustproof plate 406 will move downward with the help of the elastic force generated by the deformation of the telescopic spring 405, thereby achieving the effect of elastically clamping the port of the external device, making the port of the external device not easy to loosen, which is more practical.
