Embodiment：A kind of spiral cover for automatic polarimeter, as shown in figure 1, including placing storehouse 1, placing storehouse 1 is used to place
Tested liquid, placing storehouse 1 are hinged with lid 2, handle 3 are provided with lid 2, and rotating lid 2 by handle 3 realizes placement
The opening and closing in storehouse 1.
As shown in Figures 2 and 3, handle 3 is provided with becket 311, and becket 311 provides impetus, can facilitated to lid 2
Opening and closing, convenient operation.
Handle 3 is sheathed on rotating shaft 32, and lid 2 welds fluted 36, and rotating shaft 32 is welded on the cell wall of groove 36, rotating shaft 32
Both ends are socketed with torsion spring 321, and the one end of torsion spring 321 is connected with handle 3, and the other end of torsion spring 321 is connected with lid 2, torsion spring 321
In compressive state, torsion spring 321 has the revolving force for driving handle 3 to turn counterclockwise.
The section of groove 36 is semicircle, and the both ends of groove 36 pass through the welded seal of cover plate 37；On the arcwall face of groove 36
Block 361 is welded with, block 361 is located in the rotating path of handle 3；When block 361 contradicts handle 3, body body 3 is revolved in limitation
Turn, handle 3 can be fixed on by the effect of the elastic force of torsion spring 321 by the position of block 361, now becket 311 protrudes the surface of lid 2,
Lid 2 can be opened and closed easily for pull handle ring 311.
Lid 2 offers chute 21, and chute 21 linearly extends, and chute 21 is interconnected with groove 36.
Rectangular block 211 is placed with chute 21, slippage slot 34 is provided with rectangular block 211, slippage slot 34 exports to be connected successively
Logical chute 21 is provided with the lock-in component that barrier handle 3 freely rotates with groove 36, lid 2.Lock-in component includes sliding block 35, sliding
Block 35 is placed on 34 in slippage slot, and slippage slot 34 is welded with spring 341 away from the one end of handle 3, and the welding of spring 341 is connected in sliding block 35
End, sliding block 35 can be slid in the slippage slot 34；
As shown in figure 3, spring 341 is persistently in compressive state, spring 341 promotes sliding block 35 to skid off, and sliding block 35 is smooth
Upper surface can carry out barrier to handle 3, and limitation handle 3 screws out groove 36 counterclockwise, and now handle 3 is parallel with the surface of lid 2, holds
It is hidden in lid 2, is advantageous to attractive in appearance 3.
It is oblique surface 38 that sliding block 35, which inhales surface, and oblique surface 38, which is inclined upwardly, is arranged on lower surface, when drive handle 3 edge of exerting oneself
When being rotated towards the direction of oblique surface 38；
Handle 3 has to sliding block 35 towards the component inside slippage slot 34, this component meeting compression spring 341, makes sliding block 35
Slippage slot 34 is slipped into, sliding block 35 separates with handle 3, and handle 3 is further threaded through the barrier position of sliding block 35, and now, sliding block 35 loses
The barrier of handle 3 is gone, sliding block 35 is skidded off by the elastic force effect of spring 341, and then people stops force, and handle 3 rotates in torsion spring 321
The lower upper surface for contradicting sliding block 35 of effect, realizes the fixation of handle 3.
Sliding block 35 is welded to connect the shifting block 33 of rectangle, and employee promotes shifting block 33 can be with movable slider 35 in slippage slot back and forth
Slid in 34, shifting block 33 protrudes the surface of cover plate 2, and bearing of trend of the cover plate 2 along slippage slot 34 moves, and the upper surface of shifting block 33 is set
There is striped 39, striped 39 is the waveform to rise and fall, and striped 39 can increase and frictional force during human contact, convenient operation.
As shown in figure 4, the bottom of sliding block 35 offers circular port 352, roller 351 is placed with circular port 352, roller 35 is logical
Cross axle rotatable connection to protrude the bottom of sliding block 35 in block 35, roller 351 and contact with the bottom of chamber of slippage slot 34, roller 351 rubs sliding
Wiping is changed into rolling friction, and force of rolling friction is smaller, conveniently stirs shifting block 33, convenient operation.
Operation principle：As shown in Figure 3 and Figure 4, when needing to open lid 2, shifting block 33 is stirred, makes sliding block 35 to slippage slot
34 interior slips, sliding block 35 are separated with handle 3, and torsion spring 321 has the revolving force turned counterclockwise to handle 3, and handle 3 is not contradicted,
Handle 3 rotates to the position of block 361, and block 361 is formed to handle 3 and contradicted, and handle 3 is fixed, and becket 311 protrudes lid 2
Surface, now pull handle ring 311 lid 2 can be opened and closed, it is easy to operate；
When lid 2 need not be opened and closed, becket 311 is pushed, rotates handle 3, handle 3 contacts with oblique surface 38, holds
3 pairs of sliding blocks 35 are had towards the component inside slippage slot 34, this component meeting compression spring 341, sliding block 35 is slipped into slippage slot
34, sliding block 35 separates with handle 3, and handle 3 can skid off slippage slot 34 by the position of sliding block 35, sliding block 35, stop pushing, torsion spring
321 are in compressive state, and torsion spring 321 has the revolving force for driving handle 3 to turn counterclockwise, and sliding block 35 contradicts handle 3, by torsion spring
321 and the effect of sliding block 35, handle 3 fixed, this is simple in construction, easy to operate.
