Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 to 5, the vacuum sucker connection structure includes a bowl-shaped sucker 1 placed in an inverted manner, a connection portion 2 penetrating through the sucker 1 is arranged on the back of the sucker 1, and the connection portion 2 is arranged in an area in the middle of the sucker 1. In this embodiment, the vacuum chuck connection structure further includes a receiving base 3 engaged with the connecting portion 2, wherein the connecting portion 2 includes a rectangular protrusion 21, and the rectangular protrusion 21 extends to both sides to form a clamping edge 22. The bearing seat 3 is used for being connected with a hanging piece (not shown in the attached drawing), and the hanging piece can be any one of a hook, a hanging ring, a mop bucket or a storage rack. The bearing seat 3 can also be integrally formed with the hanging piece, so that the connection strength between the bearing seat 3 and the hanging piece is further improved. In this embodiment, the receiving seat 3 is provided with a receiving groove 31 and a first engaging groove 32 and a second engaging groove 33 respectively engaged with the two engaging edges 22; like this when connecting portion 2 inserts holding tank 31, first draw-in groove 32 outer wall and second draw-in groove 33 outer wall just take place to face the elastic deformation of first draw-in groove 32 inner wall and second draw-in groove 33 inner wall under 22 squeezing actions at two joints, thereby make two joints hold in first draw-in groove 32 and second draw-in groove 33 along 22, first draw-in groove 32 outer wall and second draw-in groove 33 outer wall resume elastic deformation afterwards, make two joints along 22 joint just in first draw-in groove 32 and second draw-in groove 33, realize connecting portion 2 and the connection of bearing seat 3. The receiving groove 31 is dimensioned to fit the connecting portion 2 and is provided with a first stopper surface 34 and a second stopper surface 35 within the receiving groove 31. The first limiting surface 34 and the second limiting surface 35 can limit the other two opposite surfaces of the rectangular protrusion 21, so that the connecting part 2 is prevented from being pulled out from the bearing seat 3 from top to bottom or from bottom to top, and the reliability of connection between the connecting part 2 and the bearing seat 3 is further improved.

In a preferred embodiment, a first opening 36 is disposed on the first limiting surface 34, and a second opening 37 is disposed on the second limiting surface 35, wherein the first opening 36 is substantially located at a midpoint of the first limiting surface 34, and the second opening 37 is substantially located at a midpoint of the second limiting surface 35, so that the outer wall of the first clamping groove 32 and the outer wall of the second clamping groove 33 can generate a slight elastic deformation far away from the two clamping edges 22 when the two clamping edges 22 are extruded, and thus the two clamping edges 22 can be clamped in the first clamping groove 32 and the second clamping groove 33 more easily and rapidly, and the connection part 2 and the bearing base 3 can be connected quickly.

In a preferred embodiment, a primary guiding slope 23 is provided on the top of the other two opposite sides of the rectangular protrusion 21, a secondary guiding slope 24 is provided on the top of the catching edge 22, and the catching edge 22 is provided below the primary guiding slope 23. A direction slope 23 can make protruding 21 of rectangle accomplish the location with holding tank 31 more fast accurate, two joint follow later on 22 more smooth and easy and quick joints are in first draw-in groove 32 and second draw-in groove 33 under the guide effect on secondary direction slope 24, make connecting portion 2 and accept seat 3 to connect more portably, swift. And bearing clamping grooves 38 can be arranged at two sides of the bearing seat 3, and the bearing clamping grooves 38 can be detachably clamped with the mop bucket or the storage rack. The bearing seat 3 can be further provided with a through hole 39, and the rectangular protrusion 21 can be inserted into the through hole 39 when passing through the accommodating groove 31, so that the material cost is further saved.

In a preferred embodiment, the vacuum sucker connecting structure further comprises a bowl-shaped dish cover 4 and a bowl-shaped framework (not shown in the attached drawing), wherein an opening is formed in the center of the dish cover 4, the dish cover 4 is sleeved on the connecting portion 2 through the opening and covers the back of the dish body 1, the dish body 1 covers the framework (not shown in the attached drawing), the framework can play a role in supporting and shaping the dish body 1 on the framework, can conduct stress to discharge air in the dish body 1, and meanwhile, the dish body 1 is extruded and attached to a base surface. Connecting portion 2 and skeleton integrated into one piece have a plurality of archs 5 with the annular array on the skeleton to arch 5 wears out the disk body 1 back. Like this when external force presses connecting portion 2 or dish cover 4, dish cover 4 oppresses disk body 1 and skeleton and annular array's arch 5, and protruding 5 gives a circumference oppression power for the disk body, makes the air of 1 inward flange of disk body further discharge, the clean formation vacuum cavity of arranging, makes disk body 1 and base plane laminating inseparabler, is difficult for droing from the base plane.

Among the above-mentioned technical scheme, holding tank 31 side that will accept seat 3 is towards connecting portion 2, it is accurate more fast and accomplish the location with holding tank 31 that a direction slope 23 makes the rectangle arch 21, press and accept seat 3 afterwards, first draw-in groove 32 outer wall and second draw-in groove 33 outer wall just take place to face the elastic deformation of first draw-in groove 32 inner wall and second draw-in groove 33 inner wall under 22 extrusion effect at two joints, two joints simultaneously along 22 under the guide effect of secondary direction slope 24 with first opening 36, smooth and easy and quick joint is in first draw-in groove 32 and second draw-in groove 33 under the combined action of second opening 37, realize connecting portion 2 and the quick connection of accepting seat 3. The first limiting surface 34 and the second limiting surface 35 prevent the connecting part 2 from being pulled out from the bearing seat 3 from top to bottom or from bottom to top, the connecting reliability of the connecting part 2 and the bearing seat 3 is high, and the connecting device is particularly suitable for hanging articles such as hooks, mop buckets, garbage cans and storage racks which are prevented from rotating.

The embodiment is only for the illustration of the concept and implementation of the present invention, and is not limited thereto, and the technical solution without substantial transformation is still within the protection scope under the concept of the present invention.
