Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art.
Embodiment two, with reference to Fig. 4 and Fig. 5, a kind of vacuum cup, including integrated casing 1, main body rack 2, suction piece 3 with
And the centring ring 4 for being used for connected with outer casing and suction piece is placed between shell and main body rack, the shell 1 is the cylinder of bottom opening
Shape, top center is provided with resigning hole 11, and the top inner wall of the shell 1 is provided with multiple moving teeth 12, and multiple moving teeth 12 are equal
It is even to be distributed in the surrounding of resigning hole 11；The main body rack 2 include base plate 21, the fixed column 24 positioned at the center of base plate 21 and with it is solid
Outer ring 22 and inner ring 23 that fixed column 24 is arranged concentrically, are additionally provided with multiple hole clippings 25 between the fixed column 24 and inner ring 23；Institute
State suction piece 3 and mention 32 including suction disc 31 and the multiple positioned at the center of suction disc 31, described to mention 32 relative with the position of hole clipping 25
Should, 32 inner sides of mentioning are provided with internal tooth 321, and 32 outsides of mentioning are provided with external tooth 322；The centring ring 4 includes setting
Put the multiple pulling holes 41 on centring ring 4 and the multiple positioned at the inwall of centring ring 4 dials platform 42, described group of platform 42 and external tooth 322
Position is corresponding；Corresponding described group of platform 42 and/or the contact surface of external tooth 322 is inclined-plane.
Moving tooth 12 is arc, and the moving tooth 12 is four, and the pulling hole 41 is arcuate socket.It is described that to mention 32 be arc,
The hole clipping 25 is arc, it is described mention 32 and hole clipping 25 be respectively three.The inwall of the centring ring 4 is provided with limit rib 43,
The position of the limit rib 43 is corresponding with the topmost position of external tooth 322.Described group of platform 42 is additionally provided with retaining rib 44 above.Institute
State the bottom inside of shell 1 and be provided with multiple anti-avulsion teeth 13, the outer wall of the outer ring 22 is provided with de- tooth slot to make way 26, the outer ring 22
Bottom outside is additionally provided with ring gear groove 28, and the de- bottom of tooth slot to make way 26 connects with ring gear groove 28, the anti-avulsion tooth 13 with it is de-
The position of tooth slot to make way 26 is corresponding.The de- bottom of tooth slot to make way 26 is outwards provided with hyoid tooth 27 of stumbling, the bottom of hyoid tooth 27 of stumbling
Groove is formed between portion and base plate 21, and closure cell body is formed with ring gear groove 28.The de- tooth slot to make way 26 and anti-avulsion tooth 13 are distinguished
It it is four, multiple de- tooth slots to make way 26 are uniformly arranged.
The outer wall of shell 1 is evenly arranged with multigroup outward appearance muscle 14, plays decoration and increases frictional force when product works.
Assembling of the invention：Arrow in accompanying drawing 4 refers to the process of sucker suction；As shown in figure 4, being arrived from above during assembling
Under be successively shell 1, centring ring 4, main body rack 2, suction piece 3；Make to mention 32 through the hole clipping on main body rack 2 on suction piece 3
25, the holding of internal tooth 321 for mentioning 32 forms clamping in the top edge of hole clipping 25, and then centring ring 4 is enclosed within the inner ring of main body rack 2
On 23, then shell 1 is fastened on outer ring 22, the anti-avulsion tooth 13 on shell 1 is by the de- tooth slot to make way 26 on outer ring 22 to tooth
Annular groove 28 is slided and gone, and anti-avulsion tooth 13 continues to overcome the resistance of hyoid tooth 27 of stumbling downwards, puts the interface arrangment that ring gear groove 28 forms stabilization under,
Avoid releasing；Moving tooth 12 is aligned on centring ring 4 pulling hole 41 while fastening is simultaneously inserted；After fastening is finished, in main body rack 2
The fixed column 24 of the heart overlaps with the resigning hole 11 on shell 1.Complete to install.
The course of work of the invention, makes to dial platform 42 and external tooth 322 vertical with reference to the detailed structure of Fig. 6 and Fig. 7, during installation
Direction does not overlap, and holds shell 1 and the suction disc 31 of suction piece 3 is pressed against on smooth metope, screws shell 1, stirs moving tooth 12
Centring ring 4 is rotated with, and is so dialled platform 42 and external tooth 322 and is come in contact by the inclined plane for setting；Now external tooth 322 is subject to power
To radial lift, and its reaction force is applied on main body rack 2 by centring ring 4, and the base plate 21 of main body rack 2 is pressed downward putting
Suction disc 31, at the same time the centre of suction disc 31 lifted by mentioning 32, such suction disc forms vacuum between 31 and metope, complete base
This absorption.
Shell 1 continues to rotate, and external tooth 322 is crossed retaining rib 44, reaches between limit rib 43 and retaining rib 44, now complete
Into absorption.Suction disc 31 sets flange collar with the contact position of base plate 21, increases pressure result, and flange collar is located at the extension of suction disc 31.
The knob direction of shell 1 is to determine that such as accompanying drawing 6,7 sets according to the relative tilt direction for dialling platform 42 and external tooth 322
Put, exactly screwed according to the direction in Fig. 4.
The part that the inner side mentioned in this programme, outside refer to sucker is all circular, is inner side towards center of circle side, separately
Side is outside.
Embodiment one, is that moving tooth 12 is three, outside centring ring 4 with the difference part of embodiment two as illustrated in the accompanying drawings from 1 to 3
Wall is provided with three shell fragments 45, and each end of shell fragment 45 outside sets a screens projection 46, and the inwall of outer ring 22 sets three
Individual fin 29 raised with the screens on shell fragment 45 46 is corresponding, and internal tooth 321 is arranged on the both sides for mentioning 32, mentions 32 tops
Holding is in the top both sides of hole clipping 25 after the installation of internal tooth 321.And limit rib 43 is integrally formed with platform 42 is dialled, compact conformation is reliable steady
It is fixed, it is completed rear shell fragment 45 and is contradicted with screens raised 46.
Remaining mechanism and to be installed on embodiment two identical, when in use, shell fragment 45 can be raised in screens when screwing shell 1
Slided on 46, click sound had when the screens projection 46 on shell fragment 45 slips over fin 29, so imply that the front end of external tooth 322 with
Limit rib 43 is contradicted, and external tooth 322 has been slid over retaining rib 44, thus is avoided that rotating through position overexerts the damage being directed at.
Internal tooth 321 in the technical program, no matter in inner side or both sides, is all to play prevent suction when sucker does not stress
Piece 3 is released, and internal tooth 321 is mentioning 32 both sides in embodiment one, is now set in the side of 25 top edge fixed column of hole clipping 24 and kept off
Block 251, mentioned when using 32 with the clamping of hole clipping 25 after the completion of, it is corresponding with block 251 to mention sections inner side on 32, can avoid extension
The top stress deformation of tooth 32 offsets to the side of fixed column 24, but the setting of block 251 can make to mention 32 remains fortune vertically
It is dynamic, it is to avoid external tooth 322 is threaded off.
Multigroup vertical outward appearance muscle 14 is set in the lateral wall of shell 1 in embodiment one, two, one is attractive in appearance, and one is
It is anti-skidding.
General principle of the invention and principal character has been shown and described above.It should be understood by those skilled in the art that,
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification,
Without departing from the spirit and scope, various changes and modifications of the present invention are possible, and these changes and improvements all fall
Enter in scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent thereof.
