Description

Technical Field

[0001] This utility model relates to the field of expansion dock technology, specifically a suction cup type fixed expansion dock. Background Technology

[0002] A docking station is an external device primarily used to expand the functionality of a laptop. It allows the laptop to easily connect to multiple external devices, such as power adapters, network cables, mice, external keyboards, printers, and external monitors, by replicating or expanding the laptop's ports. Docking stations are small in size and can be placed directly on a desktop, while also being easy to carry when traveling.

[0003] When a docking station placed on a desktop is pulled by the connecting cables, it will move and is therefore prone to falling off the desktop during use, resulting in damage. The internal structure of the docking station is delicate, and the repair cost is high and it is not easy to repair. Therefore, suction cups are usually installed on the bottom of the docking station to fix it to the desktop. However, the existing suction cups directly adhere to the desktop, and the suction force generated is limited, resulting in low stability of the docking station fixed by the suction cup.

[0004] To address this issue, the present invention provides a suction cup-type fixed expansion dock, which uses a piston to extract the air from inside the suction cup after it has been pressed, thereby solving the aforementioned problem. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a suction cup type fixed expansion dock, which solves the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suction cup type fixed expansion dock, comprising an expansion dock body, an adsorption plate at the bottom of the expansion dock body, a rotating disk rotatably connected to the bottom of the adsorption plate, an adsorption assembly at the outer end of the rotating disk, the adsorption assembly including a side rod fixedly connected to the outer end of the rotating disk, a suction cup fixedly connected to the bottom end of the side rod, air holes symmetrically opened inside the suction cup, a communicating cavity opened inside the side rod, a guide hole between the suction cup and the side rod, the guide hole communicating with the air holes, and a piston movably connected inside the communicating cavity.

[0007] Preferably, the cross-sections of the connecting cavity and the piston are both circular with the same radius, the guide hole is Y-shaped, and the adsorption assembly further includes a pressure relief hole opened at the top of the side rod, the pressure relief hole being connected to the connecting cavity.

[0008] Preferably, the adsorption assembly further includes a lead screw rotatably connected to the outer end of the piston, and the lead screw is rotatably connected to the side rod.

[0009] Preferably, the adsorption assembly further includes a cavity fixing plate fixedly connected to the outer end of the side rod, and a knob is rotatably connected inside the cavity fixing plate, the knob being threadedly connected to the lead screw.

[0010] Preferably, the side rods are provided in three sets, and the three sets of side rods are arranged in a triangle. Bolts are provided between the adsorption plate and the rotating disk. The bolts are threadedly connected to the adsorption plate and rotatably connected to the rotating disk.

[0011] Preferably, a patch is fixedly connected to the top of the adsorption plate, and a magnet is fixedly connected to the outer end of the adsorption plate. The magnets are arranged in three sets in a triangular pattern. Beneficial effects

[0012] This invention provides a suction cup type fixed expansion dock. Compared with the prior art, it has the following advantages:

[0013] 1. This suction cup-type fixed expansion dock allows the gas inside the suction cup to be expelled by pressing it, thus allowing the suction cup to adhere to the table. At this time, moving the piston outwards on the side rod increases the suction force generated by the piston inside the connecting cavity, enhancing the suction force of the suction cup on the table. This improves the stability of the expansion dock body on the table and prevents the expansion dock body from being pulled off the table and damaged during use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figure 1-4 A suction cup type fixed expansion dock includes an expansion dock body 1. The bottom end of the expansion dock body 1 is provided with an adsorption plate 2. The bottom end of the adsorption plate 2 is rotatably connected to a rotating disk 3. The outer end of the rotating disk 3 is provided with an adsorption component 4. The adsorption component 4 includes a side rod 401 fixedly connected to the outer end of the rotating disk 3. The bottom end of the side rod 401 is fixedly connected to a suction cup 402. The suction cup 402 has symmetrically opened air holes 403 inside. The side rod 401 has a connecting cavity 404 inside. A guide hole 405 is provided between the suction cup 402 and the side rod 401. The guide hole 405 is connected to the air hole 403. A piston 406 is movably connected inside the connecting cavity 404. The purpose of this setup is that, during use, the suction plate 2 is first fixed to the bottom of the dock body 1, then the rotating disk 3 is snapped onto the outer end of the suction plate 2, and the suction cup 402 at the bottom of the side rod 401 is pressed, causing the suction cup 402 to snap onto the table. During the pressing process, the gas inside the suction cup 402 is expelled, and the suction cup 402 generates a certain suction force with the table. However, some air remains inside the suction cup 402, which limits the suction force of the suction cup 402 on the table. When the dock body 1 is subjected to a large pulling force, the suction cup 402 can still separate from the table, causing the dock body 1 to fall off the table. After snapping the suction cup 402 onto the table, the piston 406 is moved, allowing the remaining gas inside the suction cup 402 to enter the interior of the connecting cavity 404 through the air hole 403 and the guide hole 405. The resulting suction force increases the adhesion of the suction cup 402 to the table, improving the stability of the dock body 1 placed on the table.

[0021] Preferably, the cross-sections of the connecting cavity 404 and the piston 406 are both circular with the same radius, and the guide hole 405 is Y-shaped. The adsorption assembly 4 also includes a pressure relief hole 407 opened at the top of the side rod 401, which is connected to the connecting cavity 404. The purpose of this arrangement is to prevent gaps between the connecting cavity 404 and the piston 406 since the cross-sectional radii of the connecting cavity 404 and the piston 406 are the same, thus avoiding gas leakage. The Y-shaped guide hole 405 enhances the efficiency of gas extraction from the suction cup 402. When the suction cup 402 needs to be removed, the piston 406 continues to move until the piston 406 moves to the left side of the pressure relief hole 407. At this time, the pressure relief hole 407, the connecting cavity 404, and the guide hole 405 are connected, allowing outside air to quickly enter the interior of the suction cup 402. At this time, the suction cup 402 separates from the table, making it convenient to remove the expansion dock body 1 from the table.

[0022] Preferably, the adsorption assembly 4 further includes a lead screw 408 rotatably connected to the outer end of the piston 406, the lead screw 408 being rotatably connected to the side rod 401. The adsorption assembly 4 also includes a cavity fixing plate 409 fixedly connected to the outer end of the side rod 401, and a knob 4010 rotatably connected inside the cavity fixing plate 409, the knob 4010 being threadedly connected to the lead screw 408. The purpose of this arrangement is that, during adjustment, rotating the knob 4010 inside the cavity fixing plate 409 causes the piston 406 connected to the lead screw 408 to move inside the communicating cavity 404, thereby generating suction or allowing air to enter the communicating cavity 404, completing the adsorption and release of the suction cup 402. Example

[0023] Please see Figure 1-4 This embodiment provides a suction cup-type fixed expansion dock technical solution based on Embodiment 1: Three sets of side rods 401 are provided, arranged in a triangular pattern. Bolts 5 are provided between the suction plate 2 and the rotating disk 3, with the bolts 5 threadedly connected to the suction plate 2 and rotatably connected to the rotating disk 3. The purpose of this arrangement is to use bolts 5 to connect the suction plate 2 and the rotating disk 3 together. Because the rotating disk 3 is rotatably connected to the bolts 5, the expansion dock body 1 can rotate during use.

[0024] Preferably, a patch 6 is fixedly connected to the top of the adsorption plate 2, and a magnet 7 is fixedly connected to the outer end of the adsorption plate 2. The magnets 7 are arranged in three sets in a triangular pattern. The purpose of this arrangement is that the patch 6 facilitates fixing the adsorption plate 2 to the bottom of the docking station body 1, and the magnets 7 generate attraction from the three corners of the adsorption plate 2 simultaneously, enhancing the stability of the adsorption plate 2 fixed to the bottom of the docking station body 1 and preventing the adsorption plate 2 from easily loosening from the docking station body 1.
