Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that specific embodiment described herein is used only for explaining the present invention, and It is not used in the restriction present invention.
As shown in Figure 1, 2, it is cut the present invention relates to a kind of dixie cup cup body and places activity box, including the first motion bar 1, driving Device, horizontal extension arm, horizontal clamping strip 4, vertical clamping strip 3, elastic inserted sheet 12 and fixed link 7;The driving device includes Driving box 2 and the telescopic rod 21 being arranged on driving box, the telescopic rod is elongated, is arranged on 21 side wall of telescopic rod Sliding slot 8, the sliding slot 8 is interior to be arranged articulated section 9, and the convex block that setting matches with sliding slot on articulated section, articulated section can be along cunning Slot is mobile, wherein in one end insertion sliding slot 8 of articulated section 9, other end rotation the first motion bar 1 of connection of the articulated section;Institute One end rotation of one end and driving box 2 for stating horizontal extension arm connects, and the horizontal extension arm includes the second motion bar 5 and third Motion bar 6;Second motion bar 5 and third motion bar 6 plug together connection, can by adjusting the second motion bar and third motion bar To change the length of horizontal extension arm, the elongated tip position for being vertically fixed on third motion bar 6 of fixed link 7;Institute It states setting in driving box 2 and pushes shaft, vertical clamping strip 3 is set on the promotion shaft, on the inner wall of first motion bar 1 Horizontal clamping strip 4 is set;Elastic inserted sheet 12 is set on vertical clamping strip 3 and horizontal extension arm, the elasticity inserted sheet 12 Height is 12cm, as shown in figure 4, the elasticity inserted sheet top side has arcwall face 16;As shown in figure 5, second activity Setting button paper groove 11 on 6 inner wall of bar 5 and third motion bar, the interior smooth arc-shaped surface with indent of button paper groove, cambered surface top Indent width is greater than the indent width of arc bottom end, first motion bar 1, driving device, horizontal extension arm and fixed link 7 Resilient balls 17 are arranged in bottom surface.
In order to increase the intensity of the first motion bar, on 7 surface of first motion bar 1, horizontal extension arm and fixed link It is respectively provided with enhancement layer 15, wherein enhancement layer 15 is arranged in carbon fashioned iron outer surface of matrix.Specifically, anti-in the setting of 15 surface of enhancement layer Become rusty plated film 18,2~3mm of thickness, laminated film-covered is arranged in 18 outer wall of antirust plated film, laminated film-covered here is polyester film.
The enhancement layer 15 is titanium alloy thin slice.
Antiskid plate 14 is set on the horizontal extension arm inner wall, and wherein 14 surface of antiskid plate has the texture of L shape.
It is in the absorbing membrane 13 of matrix arrangements on the antiskid plate 14, the height of the absorbing membrane 13 is lower than the table of antiskid plate 14 Face.
The position in width direction of vertical clamping strip can be driven by changing push shaft, while the can also be rotated One movable shaft, as shown in figure 3, can also slide the first shaft simultaneously, these design can change activity box fixed clamp The size of dixie cup is put into the first motion bar for what fixed size cup paper was overlapped, horizontal extension arm is fixed when using Neutral gear region between bar and driving device, it is ensured that horizontal clamping strip and vertical clamping strip are contacted with the side wall of cup paper, wherein pressing from both sides The antiskid plate for holding face setting can increase the effect of friction, while the absorbing membrane on antiskid plate can adsorb water and play dry work With as shown in fig. 6, the height that similarly can be applicable to glass paper is greater than when the height of cup paper is less than activity box thickness Activity box thickness avoids as shown in fig. 7, in this case, elastic inserted sheet plays further restriction effect because by paper height Wrong phenomenon caused by height is spent, simultaneously because the top of elastic inserted sheet has arcwall face, the cup paper of overlapping can be easy It is put into neutral gear region.When to dixie cup cut complete after can worker can by buckle paper groove take out be overlapped cup paper, due to First motion bar, fixed link and horizontal extension arm bottom surface are respectively provided with resilient balls, the hand-held interior recess from button paper groove upper end of people Entrance is set, can easily be slipped to the interior recessed position of the lower end of button paper groove always, worker is easily by overlapping at this time Cup paper takes out, compared with prior art, due to there is no button paper groove, causing when extracting overlapping dixie cup in the prior art It is more troublesome, increase work difficulty.
