[0002] With the rapid development of information technology, network communication equipment plays an increasingly important role in people's lives and work. Hubs, as a common network communication device, are used to connect multiple devices together to achieve data transmission and sharing.

[0003] However, traditional hubs have some problems during use. For example, when the hub is used on a desktop, it is usually placed directly on the desktop. When people accidentally pull the cable connected to the hub, it is very easy to pull the hub to move, thereby reducing the stability of the hub when used on the desktop, and even pulling the hub to the ground and damaging it. In addition, when the internal circuit board of a traditional hub is damaged and disassembled for repair, since the baffle on the hub shell is fixed with screws, tools such as screwdrivers are required when removing the baffle, which reduces the convenience of disassembling and repairing the internal circuit board of the hub. Utility Model Content

[0004] The disclosed embodiment relates to a hub with high stability. The arrangement of four suction cups improves the stability of the hub when used on a desktop, thereby preventing the hub from being pulled to the ground and damaged. Through the cooperation of the auxiliary driving component and the locking component, when the internal circuit board of the hub is damaged and needs to be disassembled and repaired, the first pinch plate and the second pinch plate can be manually pinched in opposite directions at the same time, and then the baffle can be rotated open, and then the circuit board can be directly slid backward for removal and maintenance. The disassembly process does not require the use of tools such as screwdrivers, thereby greatly improving the convenience of disassembling and repairing the internal circuit board of the hub.

[0030] Example 1: Please refer to Figures 1 to 6 :

[0031] The utility model proposes a hub with high stability, comprising: a hub shell 1, the front end surface of the hub shell 1 is uniformly provided with a rectangular through-hole, and a circuit board 108 is installed inside the hub shell 1, and the front side of the upper end of the circuit board 108 is uniformly provided with a socket 109; a suction cup 101 is fixedly connected to the four corners of the bottom end surface of the hub shell 1, and the four suction cups 101 are connected through three connecting pipes 102, and a ventilation pipe 103 is connected to the right side of the connecting pipe 102, and the upper end of the ventilation pipe 103 is connected to a threaded sealing cap 104 through a thread. The arrangement of the through tube 102, the vent tube 103 and the threaded sealing cap 104 enables the four suction cups 101 to lose the negative pressure effect by loosening and removing the threaded sealing cap 104 from the upper end of the vent tube 103 when the suction cup 101 is separated from the desktop, thereby improving the convenience of separating the four suction cups 101 from the desktop; two groups of locking assemblies 2 are symmetrically arranged on the rear side of the upper end face of the hub shell 1, and an auxiliary driving assembly 3 is arranged between the front sides of the two groups of locking assemblies 2, which is used to move the four buckles 203 in the two groups of locking assemblies 2 at the same time.

[0032] A baffle 105 is rotatably connected to the rear opening of the hub shell 1 via a rotating shaft. A slide rail 106 is fixedly connected to the left and right sides of the bottom end surface inside the hub shell 1, and a T-shaped slide groove 107 is provided on the opposite sides of the two slide rails 106 for sliding connection with the T-shaped slide bar 1010.

[0033] In at least some embodiments, a T-shaped slide bar 1010 is provided on both the left and right end faces of the circuit board 108, and a rubber strip 1011 is provided on both the front and rear side faces of the circuit board 108, improving the stability of the T-shaped slide bar 1010 when used inside the hub housing 1.

[0034] When the circuit board 108 is installed inside the hub housing 1, the two T-shaped slide bars 1010 are respectively slidably connected to the two T-shaped chutes 107.

[0035] The locking component 2 includes a support block 201, a rectangular sliding opening 202, a buckle 203, and a U-shaped clamping block 204. The support block 201 is fixedly connected to the rear side of the upper end face of the hub housing 1, and two rectangular sliding openings 202 are provided on the rear end face of the support block 201. A buckle 203 is slidably connected inside each rectangular sliding opening 202, and a spring is installed inside each rectangular sliding opening 202; the U-shaped clamping block 204 is fixedly connected to the upper side of the baffle 105; through the setting of the locking component 2, the closed baffle 105 can be limited.

[0036] When the baffle 105 is in the closed state, the buckle 203 is clamped with the inner side of the U-shaped clamping block 204, and at this time, the front end face of the baffle 105 is in close contact with the rear side face of the rear rubber strip 1011, and the front side face of the front rubber strip 1011 is in close contact with the front inner side face of the hub housing 1.

[0037] Embodiment two, on the basis of Embodiment one, as Figure 2 、 Figure 4 and Figure 6 shown, the auxiliary driving component 3 includes a first driving rod 301, a second driving rod 302, a first pinching plate 303, a second pinching plate 304, and a limiting plate 305. The first driving rod 301 is fixedly connected to the rear ends of the left two buckles 203 in the two groups of locking components 2, the second driving rod 302 is fixedly connected to the rear ends of the upper side faces of the right two buckles 203 in the two groups of locking components 2, the first pinching plate 303 is fixedly connected to the front end face of the first driving rod 301, and the second pinching plate 304 is fixedly connected to the front end face of the second driving rod 302; the limiting plate 305 is fixedly connected to the middle of the rear side of the upper end face of the hub housing 1, and the limiting plate 305 is located between the first pinching plate 303 and the second pinching plate 304; through the setting of the auxiliary driving component 3, only by pinching the first pinching plate 303 and the second pinching plate 304 with one hand, the four buckles 203 can be separated from the inner sides of the two U-shaped clamping blocks 204 respectively. Therefore, no two-handed operation is required, further improving the convenience of disassembling the circuit board 108.

[0038] The working principle of this embodiment is as follows: When the hub is used on a desktop, first place the hub on the desktop, then press the hub housing 1 downward so that the four suction cups 101 are fixed to the desktop. This prevents the hub from being pulled away even if the cable connected to the hub is accidentally pulled. Then connect the cable through the socket 109 and use it.

[0039] When the internal circuit board 108 of the hub is damaged and needs to be disassembled for repair, it is only necessary to manually pinch the first pinching plate 303 and the second pinching plate 304 in opposite directions at the same time, so that the opposite ends of the first drive rod 301 and the second drive rod 302 can be moved in opposite directions at the same time, thereby moving the buckles 203 in the two groups of locking assemblies 2 inward at the same time, so that the four buckles 203 are separated from the inner sides of the two U-shaped blocks 204 respectively. At this time, the baffle 105 loses its fixing function, and then the baffle 105 is rotated open. When the baffle 105 is rotated open, the circuit board 108 loses its fixing function, and the circuit board 108 can be directly slid backward to be removed for repair.
