Description

Technical Field

[0001] The utility model relates to a suction cup, in particular to a suction cup device and a fixing rod thereof. Background Art

[0002] Suction cups have a wide range of applications and uses in everyday life. They primarily utilize atmospheric pressure (negative pressure) to operate. The most common application is as hooks or cutlery racks in the kitchen. These products are typically fixed to smooth tile or glass surfaces using suction cups, making it convenient to hang pots, knives, or other kitchen utensils, saving space and providing easy access. Suction cup hooks can also be used in the bathroom to hang items like towels and bathrobes, preventing wet clothing from being placed directly on the floor, making it slippery. In short, suction cups, due to their simplicity, practicality, and convenience, play an important role in many aspects of life, from providing convenience in the home to assistive tools in professional fields. However, current suction cups also have certain drawbacks. After a period of time, slight gaps remain on the tile or glass surface, making it difficult for the suction cup to fully adhere to the surface. Furthermore, the edges of the suction cup tend to warp over time, making it easier for air to enter the negative pressure cavity created by the suction cup, disrupting the negative pressure and ultimately causing it to fall off. Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a suction cup device and a fixing rod thereof.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a suction cup device, comprising a suction cup and a suction cup fixing seat, one side of one end of the suction cup fixing seat is provided with a recessed suction cup fixing groove, and the other side is provided with a recessed knob groove, the fixing surface portion of the suction cup is sleeved on and fixed on a disc-shaped suction cup fixing plate, a fixing barb is fixed at the center of the outer wall of the suction cup fixing plate, the fixing barb passes through the through-hole in the center of the suction cup fixing groove, and is fixedly connected to the center of the exhaust button in the knob groove, a circular clamping knob is sleeved around the outer periphery of the exhaust button in the knob groove, and the exhaust button is supported on a circular support platform in the center of the clamping knob, the threaded barrel of the clamping knob is screwed into the thread of the side wall of the knob groove, and a pressure ring arranged around the center of the suction cup axis is provided in the suction cup fixing groove, and the pressure ring is opposite to the edge of the suction cup.

[0005] Furthermore, a raised ring protruding from the suction cup body is provided on a surface of the suction cup opposite to the pressure ring, and the raised ring is opposite to the pressure ring.

[0006] Furthermore, a fixing block perpendicular to the suction cup fixing seat is clamped on the other end of the suction cup fixing seat.

[0007] Furthermore, one end of the suction cup fixing seat provided with the fixing block is also provided with a slot structure protruding from the suction cup fixing seat body.

[0009] Furthermore, a pair of spaced apart fixing ears are provided at the outer end of the fixing block.

[0010] The utility model also relates to a fixing rod, comprising a rod body and a suction cup device as described in the claim, wherein both ends of the rod body are respectively provided with a retractable sleeve through a limiting structure, and the outer ends of the sleeves are respectively rotatably connected to the fixing ears of the suction cup device corresponding to each end through a rotating shaft.

[0011] Furthermore, the cross-sections of the rod body and the sleeve are triangular.

[0012] When the suction cup of the suction cup device of the utility model is fixed on a flat surface such as a tile or glass surface, the exhaust button is pressed down to make the suction cup adsorbed on the tile or glass surface, and then the pressing knob is turned to make the exhaust button drive the adsorbed suction cup to move relatively outward, so that under the reaction force, the suction cup fixing seat is pressed toward the suction cup, and the raised ring is opposite to the pressure ring. Therefore, the pressure ring of the suction cup fixing groove can press the raised ring on the edge of the suction cup, so that the edge of the suction cup is always pressed and closely fits on the flat surface, effectively preventing the edge of the suction cup from warping and causing the suction cup to fail under negative pressure and fall off;

[0013] In addition, both ends of the rod body of the fixed rod are provided with extendable sleeves at the same time, forming a telescopic rod structure with retractable ends. Not only can it be telescopically adjusted, but the sleeves at both ends are respectively rotatably connected to the suction cup devices, and the angles of the suction cup devices at each end and the sleeves can be adjusted so that the suction cup devices can be located on the same side and fixed on the same wall. The suction cup devices on both sides can also be fixed on the walls on both sides of the corridor, etc., and can even be fixed on the walls perpendicular to each other at the corner. The fixing method is more flexible and more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
