Description

Technical Field

[0001] The utility model relates to the technical field of USB hubs, in particular to a detachable and combinable hub. Background Art

[0002] A hub is a basic device in a data communication system and has a flow monitoring function. Like twisted pair cables and other transmission media, it is a hardware device that does not require any software support or only requires very little management software.

[0003] For example, the patent with announcement number CN213071607U discloses a detachable combined USB hub, including a base and a vertical hub vertically installed on the top of the base, a flat hub is horizontally installed on one side of the vertical hub, the inner sides of the two plug-in tubes are correspondingly inserted into the two ends of the take-up drum shaft, the main data cable is wound on the outside of the inner side of the take-up drum, one end of the main data cable is provided with an external USB plug, and the other end of the main data cable is provided with an internal USB plug.

[0004] Through the above arrangement, the utility model described in the prior art enables the take-up reel to smoothly rotate inside the base through the insertion reel, and the main data line is wound outside the take-up reel to store a certain length of the main data line inside the base, thereby expanding the distance between the base and the host and expanding the placement position of the hub, solving the problem that the data line length of the traditional hub is fixed, which limits the placement position of the hub and affects its use, and achieving the effect of facilitating the placement of the hub and facilitating the use of the hub. However, the detachable combined USB hub of the prior art solution has the following defects during operation:

[0005] After using the above device, the main data cable needs to be wound around the outer wall of the take-up drum, and this process can be achieved by simply using the compressed torsion spring to drive the take-up drum to rotate, so as to collect the data cable. However, the torsion spring will deform after being used for a period of time, resulting in the data cable not being able to be completely wound around the outer wall of the take-up drum. Moreover, when the device is in use, there is no function to limit the take-up drum, resulting in the external USB plug being forcibly pulled off from the interface under the action of the compressed torsion spring, which in turn causes the device to work unstably when in use. Utility Model Content

[0006] The utility model aims to provide a detachable and combined hub, which is mainly used to solve the technical problems of incomplete data line collection and no position limiting work for the wire reel in the prior art.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A detachable hub includes a base and a first hub, the top of the base is fixedly connected to a second hub, the side wall of the second hub is provided with a plurality of second C-slots, the side wall of the first hub is fixedly connected to a connecting plug, and the connecting plug is adapted to the second C-slots, the front end side wall of the first hub is provided with a plurality of first C-slots, the bottom of the inner wall of the base is rotatably connected to a gear, the top of the gear is fixedly connected to a wire reel, the outer wall of the wire reel is wound with a data cable, and the data cable passes through the outer wall of the base, the outer wall of the base is provided with a mounting hole, the inner wall of the mounting hole is rotatably connected to a driving assembly, the bottom of the inner wall of the base is rotatably connected to a lifting assembly, the outer wall of the base at the lower end is provided with a through hole, and the inner wall of the through hole is slidably connected to a limiting assembly.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When the device needs to store the data cable, it only needs to rotate the driving component to drive the take-up drum to rotate, and only through the take-up drum to wind all the data cables around the outer wall of the take-up drum, the driving component drives the lifting component to work during the operation, so that the data cables can be evenly wound around the outer wall of the take-up drum through the lifting component. When the work is completed, the gear is limited by the limiting component to prevent the gear from driving the take-up drum to rotate, causing the data cables to be scattered.

[0011] 2. Beneficial effects:

[0012] The prior art provides a take-up reel so that the reel can rotate smoothly inside the base, and the main data cable is wound up on the outside of the reel to store a certain length of the main data cable inside the base, thereby expanding the distance between the base and the host and expanding the placement position of the hub. However, the prior art has technical problems such as incomplete data cable collection and no limiting operation on the reel. The present solution provides a driving assembly, which can quickly wind the data cable around the outer wall of the reel through the driving assembly, and drives the lifting assembly to work when the driving assembly is working. The lifting assembly allows the data cable to be evenly wound around the outer wall of the reel through the lifting assembly, thereby preventing the data cable from being randomly wound around the outer wall of the reel.

[0016] Preferably: a fixed column is fixedly connected to the bottom of the inner wall of the base, a connecting block is fixedly connected to the side wall of the slider, and the connecting block is slidably connected to the outer wall of the fixed column.
