fig. 3 is a schematic view of the connection structure of the middle spherical plug and the threaded rod of the present invention.

The reference numbers and corresponding designations in the drawings are: 1. the novel metal tool comprises a sucker body, a disc part 2, a spherical plug 3, an air exhaust hole 4, a convex ring 5, a threaded hole 6, a threaded rod 7 and a hardware fitting connecting seat 8.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1-3, this embodiment provides a vacuum hole-plugging sucker, which includes a sucker body 1, wherein a disc portion 2 is fixedly connected to the sucker body 1, the disc portion 2 is provided with a detachable spherical plug 3 at the center thereof, and the disc portion 2 is provided with a plurality of air-pumping holes 4 communicating with the inner cavity of the sucker body 1.

When the device is used, the spherical plug 3 can be used for blocking an opening on an object to be adsorbed, the disc part 2 is tightly attached to the object to be adsorbed, and gas in the sunken cambered surface structure is pumped out through the air pumping hole 4 to form negative pressure adsorption, so that the product is transplanted.

The above-mentioned process is adsorbed through the stifled hole, consequently need not to keep away the hole positioning, can adsorb at the optimum position, has guaranteed the homogeneity of adsorption affinity and the stability when transplanting. In addition, the size change of the adaptable trompil certain limit of globular end cap 3, the commonality is strong, when the unable big trompil of shutoff of globular end cap 3, can dismantle the globular end cap 3 of more big size of change and carry out the operation. The plurality of air exhaust holes 4 not only accelerate the air exhaust efficiency, but also increase the fault tolerance rate.

Wherein, the disc part 2 is fixed with the sucker body 1 through glue.

Further, the edge of the disk part 2 is provided with a convex ring 5, and the convex ring 5 is positioned on one side of the disk part 2 far away from the cambered surface structure. The protruding ring 5 plays a role in positioning when the disc portion 2 is fixed to the suction cup body 1, and can increase the connection area.

Wherein, the center of the disk part 2 is provided with a threaded hole 6, the spherical plug 3 is connected with a threaded rod 7, and the threaded rod 7 is connected with the threaded hole 6. And the size of the spherical plug 3 can be changed by adopting a threaded connection mode, so that different requirements in actual processing are met.

Specifically, each air exhaust hole 4 is circumferentially and uniformly distributed on the outer side of the spherical plug 3, and an interval exists between each air exhaust hole 4 and the spherical plug 3. The arrangement mode enables the stress of the disc part 2 to be increased uniformly, and the large-size spherical plugs 3 can be prevented from blocking the air exhaust holes 4 at intervals, so that the normal use of the disc part is ensured.

The disc portion 2 and the spherical plug 3 are made of elastic rubber material. In order to ensure that the disc part 2 and the spherical plug 3 meet the requirements of deformation and restoration, the sealing performance in the adsorption process is ensured.

In addition, the one end that the sucking disc body 1 kept away from disc portion 2 is provided with gold utensil connecting seat 8.

The present invention is not limited to the above specific embodiments, and for those skilled in the art, the above conception can be used without any creative work, and all the changes made fall within the protection scope of the present invention.
