Detailed Description

As shown in fig. 1 to 4, a suction cup includes a chassis 100 and a suction cup 200, the chassis 100 has a cavity 110 for the suction cup 200 to form a negative pressure cavity, a circular truncated cone 120 for pressing the suction cup 200 to be attached to an absorption surface is disposed on an outer edge of the chassis 100, an annular protrusion 130 is disposed on a waist portion of the chassis 100 located on the cavity 110, a lower end surface of the annular protrusion 130 does not exceed a horizontal surface of the circular truncated cone 120 or is located on the same horizontal surface as the circular truncated cone 120, when a conventional suction cup 200 absorbs the absorption surface, because the annular protrusion 130 does not limit the movement of the suction cup 200, a contact area between the suction cup 200 and the absorption surface is small, a sealing effect is poor, and the absorption is not stable enough, in this embodiment, the annular protrusion 130 is added on the waist portion of the chassis 100, when the suction cup 200 absorbs the absorption surface, the annular protrusion 130 contacts the suction cup 200, so that a contact area between an extension of the suction cup 200 and the absorption surface is large, thereby improving the adsorption effect and the adsorption stability, wherein the adsorption surface refers to a plane with a smooth surface, such as glass, a smooth table surface, a vehicle body plane and the like; the annular protrusion 130 is disposed at the waist of the chassis 100 in the cavity, which means that the annular protrusion 130 is disposed at the middle of the cavity 110 of the chassis 100.

The back of the base plate 100 corresponding to the cavity 110 is arc-shaped, and the arc-shaped arch is favorable for production and processing, and meanwhile, the appearance is improved.

The lower surface of the circular truncated cone 120 is provided with at least one annular convex rib 121; the annular rib 121 is used for pressing the contact surface of the suction cup 200 and the adsorption surface, and improves the adsorption sealing performance.

The lower surface of the circular truncated cone 120 is provided with three annular convex ribs 121, and thus the chassis 100 and the sucker 200 are further improved to be matched with each other to better adsorb and attach on the adsorption surface by the aid of the three annular convex ribs 121, and further adsorption tightness and adsorption effect are improved.

Still including being used for drawing sucking disc 200 and chassis 100 cooperation and forming the handle 300 that pulls in negative pressure chamber, sucking disc 200 has traction portion 210, chassis 100 has the hollow protruding post 140 that supplies traction portion 210 insert motion, hollow protruding post 140 both sides are equipped with the through-hole that runs through, traction portion 210 inserts in the hollow protruding post 140 and through round pin axle 400 with pull handle 300 cooperation assembly, thereby it forms the negative pressure chamber to make sucking disc 200 and absorption surface adsorb through traction portion 210 that pulls handle 300 drive sucking disc 200, pulls handle 300 and sucking disc 200's traction portion 210 through round pin axle 400 through connection assembly.

The utility model provides a sucker, which is characterized in that an annular bulge is additionally arranged in the sucker, the annular bulge is matched with the sucker to ensure that the contact area between the sucker and an adsorption surface is larger, the sealing effect is stronger, and the stability and the adsorption effect when the sucker and the adsorption surface are adsorbed are ensured; and the product has simple structure, low manufacturing cost, good use effect and high practicability.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to explain the principles of the utility model, and that various modifications and alterations can be made by those skilled in the art without departing from the spirit and scope of the utility model.
