Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a degradable PLA polylactic acid product plastic cup comprises a support box 1 and a cup body 4 mounted on the outer top wall of the support box 1, a cup handle 3 is arranged on the outer side wall of the cup body 4, the cup handle 3 and the cup body 4 are both made of PLA polylactic acid plastic, suckers 7 are fixed on four corners of the outer bottom wall of the support box 1, rectangular movable holes 8 are formed on both sides of the top wall of the support box 1, a vertical rectangular first clamp plate 2 and a vertical rectangular second clamp plate 5 are movably sleeved inside the two movable holes 8 respectively, the mutually close side walls of the first clamp plate 2 and the second clamp plate 5 are respectively contacted with the outer side walls of both sides of the cup body 4, the first clamp plate 2 and the second clamp plate 5 are both slidably connected to the inner bottom wall of the support box 1, a vertical rectangular fixing column 9 is fixed at the middle position of the inner bottom wall of the support box 1, a horizontal lifting plate 10 is in clearance fit with the outer ring of the fixing column, all articulated on the lateral wall that is located the inside first splint 2 of supporting box 1 and is close to each other with second splint 5 have the transfer line 11 that is the slope setting, the one end that two transfer lines 11 are close to each other articulates respectively at the both sides side of lifter plate 10, the roof of lifter plate 10 and the interior roof of supporting box 1 are connected with spring 14, spacing groove 12 has been seted up on the outer diapire of cup 4, be fixed with stopper 13 on the outer roof of supporting box 1, stopper 13 clearance fit is in the inside of spacing groove 12.

The second clamping plate 5 positioned above the supporting box 1 is fixedly connected with a handle 6 on the side wall far away from the cup body 4, so that the second clamping plate 5 can be conveniently pulled.

First anti-skidding groove and second anti-skidding groove have been seted up respectively on the mutual lateral wall that is close to of first splint 2 and second splint 5, multiplicable first splint 2 and second splint 5 and the static friction force between the cup 4.

The spout has all been seted up along length direction in the both sides of the interior diapire of supporting box 1, and it is provided with the slider to slide in the spout, and first splint 2 and second splint 5 are fixed respectively on the top of two sliders, can ensure that first splint 2 and second splint 5 can steadily horizontal migration.

The end of the two transmission rods 11 away from each other is higher than the end of the two transmission rods 11 close to each other, and since the height of the end of the two transmission rods 11 close to each other is fixed, when the end of the two transmission rods 11 close to each other rises, the ends of the two transmission rods 11 away from each other are caused to move away from each other.

The top end of the fixed column 9 is contacted with the inner top wall of the supporting box 1, and the spring 14 is sleeved on the outer ring of the fixed column 9, so that the spring 14 can be prevented from generating excessive deformation due to long-term expansion.

The working principle is as follows: before the plastic cup is placed on a desktop, firstly, the supporting box 1 is pressed to enable the sucker 7 to be effectively adsorbed on the desktop, the supporting box 1 can be effectively fixed on the desktop, then, the handle 6 is pulled leftwards to drive the second clamping plate 5 to horizontally move leftwards, the left end of the left transmission rod 11 can be moved leftwards, the right end of the left transmission rod 11 can be enabled to drive the lifting plate 10 to lift, the end, close to each other, of the two transmission rods 11 can be enabled to lift, the end, far away from each other, of the two transmission rods 11 can be enabled to be far away from each other, the first clamping plate 2 and the second clamping plate 5 can be enabled to be far away from each other until the distance between the first clamping plate 2 and the second clamping plate 5 is larger than the distance between the outer side walls of the two sides of the cup body 4, at the moment, the spring 14 is in a compressed state, then, the cup body, the handle 6 is released again, elastic potential energy effect through spring 14, can make the bottom of spring 14 promote lifter plate 10 and descend, can make the one end that two transfer lines 11 are close to each other descend, can make the one end that two transfer lines 11 kept away from each other close to each other, can drive first splint 2 and second splint 5 and be close to each other, press from both sides tight cup 4 until first splint 2 and second splint 5, can effectually fix cup 4 on the outer roof of supporting box 1, thereby with the effectual fixing on the desktop of plastic cup, can prevent that the plastic cup from toppling over because of accidental collision, cup 4 and cup 3 are made by PLA polylactic acid plastics, PLA polylactic acid has good biodegradability, can be degraded by the microorganism in nature completely after the use, finally generate carbon dioxide and water, can avoid causing white pollution.
