Description

Technical Field

[0001] The utility model relates to the field of extenders, and more specifically, to a device - side extender for USB long - distance transmission. Background Technique

[0002] Device - side extenders for USB long - distance transmission are mostly used in devices that require long - distance connection, such as conference room equipment, industrial control systems, medical equipment, surveillance cameras, etc. For example, remote cameras, sensors, or other devices that need to transmit data over a long distance can help overcome the limitation of the ordinary USB connection length and are applicable to various professional and industrial applications that require remote USB connection, capable of overcoming the limitation of the traditional USB connection distance.

[0003] However, most of the current device - side extenders for USB long - distance transmission have the following problems:

[0004] First, for the existing device - side extenders for USB long - distance transmission, when in use, the length of the connecting wire of the USB extender is mostly in a fixed state. If the connecting wire is long and the connection position is close, it is easy for the long connecting wire to get entangled. If the connecting wire is short and the connection position is far, it is easy to affect the connection and usage effect, and the length of the connecting wire cannot be adjusted according to the usage situation.

[0005] Second, for the existing device - side extenders for USB long - distance transmission, when in use, most of the connecting wires of the USB extender are exposed. After long - term use, the surface of the connecting wire is easy to stick with dust and impurities. If not cleaned, it is easy to affect the hygiene and safety of the device, and it is inconvenient to clean the dust and impurities on the surface of the connecting wire conveniently.

[0006] Therefore, we make improvements and propose a device - side extender for USB long - distance transmission. Content of the Utility Model

[0007] The purpose of the present utility model is to address the problems that the length of the connecting wire cannot be adjusted according to the usage situation and it is inconvenient to clean the dust and impurities on the surface of the connecting wire conveniently.

[0009] A device - side extender for USB long - distance transmission to improve the above problems.

[0010] Specifically, this application is as follows:

[0011] It includes an installation housing, on which a connecting rod is rotatably connected. A material roll is fixedly connected to the connecting rod, and a USB connecting wire is wound around the material roll.

[0012] As a preferred technical solution of the present application, the connecting rod is fixedly connected to the central part inside the rotating housing, and the inner surface of the limiting plate is in contact with the inner surface of the connecting rod.

[0013] As a preferred technical solution of the present application, the positioning holes are distributed at equal angles on the installation housing and the material roll, and the clamping rods are symmetrically distributed on the left and right sides of the limiting plate.

[0014] As a preferred technical solution of the present application, the sliders are symmetrically distributed on the left and right sides inside the installation frame, and the sliders and the cleaning cotton blocks correspond to the second springs one by one.

[0019] 1. A material roll is provided; when adjusting the length of the USB connection cable, the connecting frame can be pulled to drive the limiting plate to move. When the limiting plate moves, it can squeeze the first spring. At the same time, the limiting plate can withdraw the clamping rod from the mounting housing and the material roll back into the rotating shell. When the rotating shell is unobstructed, the rotating shell can be rotated to drive the connecting rod to rotate. When the connecting rod rotates, it can drive the material roll to rotate. The material roll can loosen the wound USB connection cable to extend the length of the USB connection cable for use.

[0035] Embodiment 2:

[0036] Next, the solution in Embodiment 1 will be further introduced in combination with the specific working mode, as described in detail below:

[0037] As Figure 3 shown, as a preferred embodiment, on the basis of the above method, further, the connecting rod 2 is fixedly connected to the central part inside the rotating housing 7, and the inner side surface of the limiting plate 9 is in contact with the inner side surface of the connecting rod 2, which can ensure that the limiting plate 9 can move smoothly through the support of the inner side surface of the connecting rod 2.

[0038] As Figure 3 shown, as a preferred embodiment, on the basis of the above method, further, the positioning holes 11 are distributed at equal angles on the installation housing 1 and the material roll 3, and the clamping rods 10 are symmetrically distributed on the left and right sides of the limiting plate 9, which can ensure that the two clamping rods 10 can be stably clamped in the positioning holes 11 for limiting and fixing.

When the USB connecting wire 4 is wound into the mounting shell 1, it can be cleaned through the cleaning cotton block 15 in the mounting frame 13. After the treatment is completed, when it is necessary to replace the cleaning cotton block 15, the pull rod 18 can be pulled to drive the connecting plate 17 to move. When the connecting plate 17 moves, it can squeeze the second spring 16. At the same time, the clamping block 19 on the pull rod 18 can be disengaged from the mounting frame 13 and the slider 14. When the slider 14 is unobstructed, the slider 14 can be taken out of the mounting frame 13 to disassemble and replace the installed cleaning cotton block 15. When fixing and limiting the replaced cleaning cotton block 15, the slider 14 can be reset in the mounting frame 13, and the pull rod 18 is released. Driven by the second spring 16, the connecting plate 17 and the pull rod 18 are reset, and the clamping block 19 on the pull rod 18 can be clamped in the mounting frame 13 and the slider 14 to play a role in fixing and limiting, which is convenient for cleaning use.
