Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figures 1 to 14As shown, an adsorption assembly for a child seat includes a suction cup 1, an adsorption base 2, a locking link 3, a locking slider 4, and a handle 5. The adsorption base 2 has an adsorption cavity 21. The top of the suction cup 1 is connected to one end of the locking link 3, and the other end of the locking link 3 has a locking slider 34. Both the suction cup 1 and the locking link 3 are movably inserted into the adsorption cavity 21 of the adsorption base 2. The adsorption cavity 21 is conical. The top of the adsorption base 2 is slidably connected to the locking slider 4. The locking slider 4 has a sliding groove 43 and an adsorption drive part 41. The top of the locking link 3 is movably inserted into the sliding groove 43, and the locking slider 34 is movably pressed against the adsorption drive part 41. The adsorption drive part 41 is used to push the locking slider 34 upward to make the suction cup 1 adsorb onto the contact surface, thereby achieving a firm adsorption of the suction cup 1. The handle 5 is provided with a threaded post 51, which is connected to the child seat by threads. The threaded post 51 is also rotatably connected to the locking slider 4. When the handle 5 is rotated, the handle 5 drives the locking slider 4 to move through the threaded post 51, so as to realize the adsorption and release of the suction cup 1.

[0017] The suction component is easy to use and can be used with child seats to quickly fix and remove the child seats in various places. It is convenient to use and can effectively ensure the suction force when fixing, so that the suction cup 1 is firmly attached, improving safety and stability during use.

[0018] The bottom of the locking link 3 is provided with a connecting plate 31, and the top of the suction cup 1 is provided with a connecting groove 14. The connecting plate 31 is inserted into the connecting groove 14 to realize the connection between the locking link 3 and the suction cup 1.

[0019] The adsorption drive unit 41 includes a free section 411, a locking inclined section 412, and a locking retaining section 413 connected in sequence. When the free section 411 is arranged opposite to the locking slide bar 34, the locking slide bar 34 is in a free state. At this time, the suction cup 1 is not under force and can be pressed against the contact surface. The locking retaining section 413 is used to keep the suction cup 1 in an adsorption state. The height of the locking retaining section 413 is greater than the height of the free section 411. The locking inclined section 412 is inclined to connect the locking retaining section 413 and the free section 411, so that the locking slide bar 34 can move smoothly from the free section 411 to the locking retaining section 413.

[0020] To facilitate the separation of the suction cup 1 from the contact surface, the circumferential surface of the suction cup 1 is provided with several pull-out discs 12. Three pull-out discs 12 are arranged in a circular array. When the child seat needs to be moved, with the locking lever 3 in the released state, pinch the pull-out disc 12 with your fingers and pull the suction cup 1 upwards, causing the suction cup 1 to separate from the contact surface from its edge, easily separating the suction cup 1 from the contact surface. Furthermore, to increase anti-slip performance and make it easier for fingers to apply force without slipping on the pull-out disc 12, the pull-out disc 12 is provided with pull-out protrusions 13. The pull-out protrusions 13 can be symmetrically arranged on both sides of the pull-out disc 12, increasing friction for both fingers. The pull-out protrusions 13 can be circular, matching the pull-out disc 12 for an aesthetically pleasing appearance.

[0021] The top of the adsorption base 2 is provided with a sliding guide rail 25, which is symmetrically arranged on both sides of the top of the adsorption base 2. The bottom of the locking slider 4 is provided with a sliding groove 43, which is movably inserted into the sliding guide rail 25 to guide the movement direction of the locking slider 4. To facilitate the installation of the sliding guide rail 25, the top of the adsorption base 2 is provided with a rectangular sliding seat 22, with the sliding guide rail 25 symmetrically located on both sides of the top of the sliding seat 22. The sliding seat 22 is provided with a lifting hole 24, which communicates with the adsorption cavity 21, and the locking connecting rod 3 is movably inserted into the lifting hole 24.

[0022] To prevent the locking slide bar 34 from rotating and from sliding out of the adsorption drive unit 41, a guide block 33 is provided on the locking connecting rod 3, and a guide groove 26 is provided on the adsorption seat 2. The guide block 33 is movably inserted into the guide groove 26. The guide block 33 is vertically arranged and symmetrically located on both sides of the locking connecting rod 3. The guide groove 26 is located on both sides of the lifting hole 24. The guide groove 26 matches the guide block 33. The guide groove 26 is movably inserted into the guide block 33, so that the locking connecting rod 3 cannot rotate and can only move up and down in the vertical direction.

[0023] One end of the threaded post 51 of the handle 5 is provided with a rotating shaft 53 and a rotating disk 52 connected to the rotating shaft 53; one end of the locking slider 4 is provided with a limiting groove 45 and a rotating groove 46 communicating with the limiting groove 45. The rotating shaft 53 is movably disposed in the limiting groove 45, and the rotating disk 52 is movably disposed in the rotating groove 46. The rotating shaft 53 and the rotating disk 52 realize the rotational connection between the handle 5 and the locking slider 4, so that the locking slider 4 can move forward or backward with the rotation of the handle 5.

[0024] To further improve the reliability of adsorption, a clamping ring 27 is provided on the adsorption seat 2, which is positioned opposite to the suction cup 1. The clamping ring 27 reduces the contact area with the suction cup 1, thereby increasing the local clamping force and improving the sealing between the suction cup 1 and the contact surface. Simultaneously, when the locking rod 3 rises, the adsorption seat 2 is forced downwards to press the suction cup 1 firmly against the contact surface. Multiple clamping rings 27 can be arranged in a coaxial array.

[0025] To facilitate the connection between the suction seat 2 and the child seat, the bottom of the suction seat 2 has three connecting screw holes 23 in a circular array, which are fixed to the child seat by screws.
