Description

Technical Field

[0001] This utility model relates to the field of computer accessories technology, and in particular to a connection device between a computer and an external device. Background Technology

[0002] With the continuous development of technology, computers are widely used in people's production and life. When using a computer, it is usually necessary to connect external devices to the computer through connectors. Existing connectors do not have the function of evenly winding up data cables. During the winding process, the cables are prone to tangling and knotting, which cannot meet the needs of users and greatly reduces the practicality of the device.

[0003] The prior art CN218386079U discloses a connection device between a computer and an external device. An external controller simultaneously activates a micro drive motor and a micro forward / reverse motor. The micro drive motor drives a first rotating rod to rotate, which in turn drives a take-up drum to rotate. The take-up drum then drives the input wire to be wound up. During the winding process, the micro forward / reverse motor drives a second rotating rod to rotate, which in turn drives a second gear to rotate. The second gear then drives a first gear to rotate, which in turn drives a threaded rod to rotate. The threaded rod causes a threaded sleeve to move to one side, which in turn causes a support rod, support plate, and limiting ring to move to one side. This repeated motion achieves uniform winding.

[0004] However, the aforementioned connection device is prone to detachment due to slight pulling during connection, resulting in data transmission failure and affecting work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a connection device between a computer and an external device, which aims to solve the technical problem that existing connection devices are prone to disconnection due to slight pulling during connection, resulting in data transmission failure and affecting work efficiency.

[0006] To achieve the above objectives, this utility model provides a connection device for a computer and an external device, including a connection box, an inspection cover, a winding component, a connecting wire, a connector, a support ring, a limiting component, and a control component. The inspection cover is detachably connected to the connection box and is located outside the connection box. The winding component is used to wind up the connecting wire, which is located inside the connection box, with both sides of the connecting wire passing through the upper and lower sides of the connection box respectively. The connector is provided on both sides of the connecting wire. There are two support rings, which are respectively provided on the upper and lower sides of the connection box and located outside the connectors. The limiting component is used to restrict the movement of the connecting wire, and the control component is used to control the operation of the winding component and the limiting component.

[0007] The winding component includes a drive motor and a retaining ring. The drive motor is located inside the connecting box, and the connecting wire is sleeved on the outside of the output shaft of the drive motor. The retaining ring is located on the side of the output shaft of the drive motor near the inspection cover.

[0008] The limiting component includes a hydraulic telescopic rod and a limiting ring. The hydraulic telescopic rod is disposed inside the support ring, and the limiting ring is connected to the output end of the hydraulic telescopic rod and is located on the side of the hydraulic telescopic rod near the connecting line.

[0009] The control unit includes a first start / stop button and a second start / stop button. The first start / stop button is electrically connected to the drive motor, and the second start / stop button is electrically connected to the hydraulic telescopic rod. Both the first start / stop button and the second start / stop button are located outside the connection box on the side away from the inspection cover.

[0010] The connection device between the computer and the external device also includes a fixing screw, which is detachably connected to the inspection cover, abuts against the connection box, and penetrates the inspection cover.

[0011] This utility model discloses a connection device for a computer and external devices. By installing or removing the inspection cover outside the connection box, components inside the connection box can be repaired or replaced when they malfunction. The winding component winds up or unwinds the connecting cable. Winding up the connecting cable prevents it from becoming tangled and knotted, thus avoiding inconvenience during normal use. When the connecting cable is unwound, a limiting component restricts and fixes its position. This prevents the connecting cable from easily detaching due to slight pulling during connection, which could lead to data transmission failure and reduced work efficiency. This invention solves the problem of existing connection devices easily detaching due to slight pulling, resulting in data transmission failure and reduced work efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] First Embodiment

[0019] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the computer and external device connection device according to the first embodiment of this utility model. Figure 2 This is a cross-sectional view along the drive motor 107 of the computer-external device connection device according to the first embodiment of this utility model. Figure 3 This is a computer and external device connection device according to the first embodiment of the present invention. Figure 2 Enlarged view of point A.

[0020] This utility model provides a connection device between a computer and an external device, comprising a connection box 101, an inspection cover 102, a winding component, a connecting cable 103, a connector 104, a support ring 105, a limiting component, a control component, and a fixing screw 106. The winding component includes a drive motor 107 and a fixing ring 108. The limiting component includes a hydraulic telescopic rod 109 and a limiting ring 110. The control component includes a first start / stop button 111 and a second start / stop button 112. This solution solves the problem that existing connection devices are prone to detachment due to slight pulling during connection, leading to data transmission failure and affecting work efficiency. It is understood that this solution can be used in scenarios where external devices are connected to a computer.

[0021] In this embodiment, by installing or removing the inspection cover 102 outside the connection box 101, components inside the connection box 101 can be repaired or replaced when they malfunction. The winding component is used to wind or unwind the connecting wire 103. Winding the connecting wire 103 allows it to be stored, preventing it from getting tangled and causing inconvenience during normal use. When the connecting wire 103 is unwound, the limiting component limits and fixes its position. This limits and fixes the position of the connecting wire 103 extending from the connection box 101 when it is in use, thus preventing the connector 104 from easily coming loose due to slight pulling during connection, which could lead to data transmission failure and affect work efficiency. This solves the problem that existing connection devices are prone to connection detachment due to slight pulling, resulting in data transmission failure and affecting work efficiency.

[0022] The inspection cover 102 is detachably connected to the connecting box 101 and is located outside the connecting box 101. The winding component is used to wind up the connecting line 103, which is located inside the connecting box 101. Both sides of the connecting line 103 pass through the upper and lower sides of the connecting box 101, respectively. Connecting heads 104 are respectively provided on both sides of the connecting line 103. Two support rings 105 are provided on the upper and lower sides of the connecting box 101, located outside the connecting heads 104. The limiting component is used to restrict the movement of the connecting line 103. The control component is used to control the movement of the connecting line 103. The operation of the take-up component and the limiting component, since the inspection cover 102 is detachably connected to the connection box 101, allows the inspection cover 102 to be installed or removed outside the connection box 101. This allows for the repair or replacement of components when they malfunction inside the connection box 101. The two sides of the connecting line 103 extend from the upper and lower sides of the connection box 101, respectively, allowing for adjustment of the length of the connecting line 103 extending outside the connection box 101. This, in turn, allows for adjustment of the position of the connector 104, enabling the connector 104 to connect external devices at different locations to the computer.

[0023] Secondly, the drive motor 107 is disposed inside the connecting box 101, and the connecting wire 103 is sleeved on the outside of the output shaft of the drive motor 107. The fixing ring 108 is disposed on the side of the output shaft of the drive motor 107 near the inspection cover 102. After the drive motor 107 is started, the power output by the output shaft of the drive motor 107 drives the connecting wire 103 outside the output shaft of the drive motor 107 to be wound or unwound. The fixing ring 108 can restrict the winding position of the connecting wire 103 outside the output shaft of the drive motor 107 to prevent the connecting wire 103 from slipping out of the output shaft of the drive motor 107 during winding.

[0024] Furthermore, the hydraulic telescopic rod 109 is disposed within the support ring 105, and the limiting ring 110 is connected to the output end of the hydraulic telescopic rod 109 and is located on the side of the hydraulic telescopic rod 109 near the connecting line 103. The output end of the hydraulic telescopic rod 109 is connected to the limiting ring 110 and drives the limiting ring 110 to move laterally outside the connecting line 103.

[0025] In addition, the first start / stop button 111 is electrically connected to the drive motor 107, and the second start / stop button 112 is electrically connected to the hydraulic telescopic rod 109. Both the first start / stop button 111 and the second start / stop button 112 are located on the side of the connecting box 101 away from the inspection cover 102. Since the first start / stop button 111 is electrically connected to the drive motor 107, pressing the start or stop button of the first start / stop button 111 can control the drive motor 107 to start or stop. Since the second start / stop button 112 is electrically connected to the hydraulic telescopic rod 109, pressing the start or stop button of the second start / stop button 112 can control the hydraulic telescopic rod 109 to start or stop.

[0026] Finally, the fixing screw 106 is detached from the inspection cover 102 and abuts against the connecting box 101, and penetrates the inspection cover 102, so that the inspection cover 102 can be fixed outside the connecting box 101 by the fixing screw 106.

[0027] When using this utility model, when it is necessary to connect an external device to a computer using the connector 104, press the start button of the first start / stop button 111 so that the first start / stop button 111 can control the drive motor 107 to start. After the drive motor 107 starts, the power output from the output shaft of the drive motor 107 drives the connecting wire 103 outside the output shaft of the drive motor 107 to wind or unwind. At this time, the fixing ring 108 can restrict the winding position of the connecting wire 103 outside the output shaft of the drive motor 107 to prevent the connecting wire 103 from sliding out of the output shaft of the drive motor 107 during winding, allowing the connecting wire 103 to unwind. When the connecting wire 103 is unwound to a suitable length, press the stop button of the first start / stop button 111 so that the first start / stop button 111 can control the drive motor 107 to stop running, thereby preventing the connecting wire 103 from continuing to unwind.

[0028] Then, press the start button of the second start / stop button 112, so that the second start / stop button 112 can control the hydraulic telescopic rod 109 to start. After the hydraulic telescopic rod 109 is started, the power output from the output end of the hydraulic telescopic rod 109 drives the limiting ring 110 to move laterally outside the connecting line 103. This allows the limiting ring 110 to limit and fix the position of the connecting line 103 extending from the connecting box 101, thereby avoiding the situation where the connector 104 is easily disconnected due to slight pulling during connection, which would ultimately lead to data transmission failure and affect work efficiency. This solves the problem that existing connection devices are prone to disconnection due to slight pulling during connection, resulting in data transmission failure and affecting work efficiency. By adjusting the length of the connecting line 103 extending outside the connecting box 101, the position of the connector 104 can be adjusted so that the connector 104 can connect external devices at different locations to the computer.

[0029] When a component inside the connecting box 101 malfunctions, the fixing screws 106 are removed sequentially from the inspection cover 102 and the through hole of the connecting box 101, thereby allowing the inspection cover 102 to be removed from the outside of the connecting box 101. This facilitates the repair or replacement of the component when it malfunctions. After the component inside the connecting box 101 has been repaired or replaced, the fixing screws 106 are gradually screwed into the inspection cover 102 and the connecting box 101, thereby allowing the inspection cover 102 to be installed outside the connecting box 101. This seals the internal space of the connecting box 101, preventing dust and other impurities from entering the connecting box 101.

[0030] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
