Specifically, when the first cover 31 rotates clockwise, the first cover 31 will drive the second connecting rod 332 to move to the left through the first connecting rod 331, and then the second connecting rod 332 moving to the left will drive the second connecting rod 332 to move to the left. The cover 32 rotates counterclockwise until the first cover 31 and the second cover 32 are completely closed.

As shown in Figure 5, a damper 34 is provided between the first cover 31 and the inner cylinder 3, and the damper 34 is used to slow down the rotation speed of the first cover 31 and the second cover 32, preventing the first cover from 31 and the second cover 32 rotate too fast and collide with each other to make a sound, and at the same time avoid the problem that the first cover 31 and the second cover 32 run into the user due to too fast rotation. Those skilled in the art can understand that, on the premise that the damper 34 can slow down the rotation speed of the first cover 31 and the second cover 32, the damper 34 can be set to any number and to any position, for example, A damper 34 is provided between the first cover 31 and the inner cylinder 3 , and between the second cover 32 and the inner cylinder 3 . Those skilled in the art can understand that, on the premise that the damper 34 can slow down the rotational speed of the first cover 31 and the second cover 32, the damper 34 can also be any form of damper, for example, a hydraulic damper , rotary damper, viscous damper, etc.

Continuing to refer to FIG. 4 and FIG. 5 , the first cover 31 is pivotally connected to the inner tube 3 via a first rotating shaft 35 , and the damper 34 is disposed on the first rotating shaft 35 . The second cover 32 is pivotally connected to the inner cylinder 3 through a second rotating shaft 36 .

One end of the first torsion spring 37 is connected to the first cover 31 , and the other end of the first torsion spring 37 is connected to the inner tube 3 , so that the first cover 31 can be fully opened automatically when opened. One end of the second torsion spring 38 is connected to the second cover 32 , and the other end of the second torsion spring 38 is connected to the inner tube 3 , so that the second cover 32 can be fully opened automatically when opened. Since there is a linkage mechanism 33 between the first cover body 31 and the second cover body 32, those skilled in the art can only set the second shaft on the first rotating shaft 35 between the first cover body 31 and the inner cylinder 3 according to needs. A torsion spring 37, or only a second torsion spring 38 on the second shaft 36 between the second cover 32 and the inner tube 3, can also realize the automatic opening of the first cover 31 and the second cover 32.

As shown in FIG. 2 , FIG. 3 and FIG. 5 , the first cover 31 is provided with a button 311 , two side hooks 312 and a main hook 313 . Two side locking slots 321 and a main locking slot 322 are disposed on the second cover body 32 , and a small hook 3221 is also disposed in the main locking slot 322 . When the first cover 31 and the second cover 32 are closed as shown in FIG. 4 , the two side hooks 312 snap into the corresponding side slots 321 respectively, and the main hook 313 snaps into the main slot 322 And it is stuck by the small buckle 3221. The locked main hook 313 and the two side hooks 312 can lock the first cover 31 and the second cover 32 to keep the first cover 31 and the second cover 32 closed. When the first cover 31 and the second cover 32 need to be opened, the user only needs to press the button 311, so that the two side hooks 312 and the main hook 313 move downward to disengage from the side hook 321 and the main hook 322 . Furthermore, the second cover 32 rotates in the opening direction under the action of the second torsion spring 38 , and the rotating second cover 32 will drive the first cover 31 to rotate in the opening direction until it is fully opened. Those skilled in the art can understand that after the first cover body 31 and the second cover body 32 have rotated through a certain angle, since the hooks 312, 313 and the slots 321, 322 are out of the mating position, the user can release the Button 311.

When the first cover 31 and the second cover 32 are opened from the locked state shown in FIG. 3 , the user manually presses the button 311 , and the hooks 312 , 313 come out of the slots 321 , 322 respectively. The second cover 32 is rotated toward the opening direction under the action of the second torsion spring 38 , and the rotating second cover 32 acts on the first cover 31 through the linkage mechanism 33 . The first cover 31 rotates in the opening direction under the action of the first torsion spring 37 and the linkage mechanism 33 . When the first cover 31 and the second cover 32 are opened to a position where the hooks 312 , 313 and the slots 321 , 322 are disengaged, the user can release the button 311 . At this time, under the action of the linkage mechanism 33 , the first torsion spring 37 and the second torsion spring 38 , the first cover 31 and the second cover 32 rotate synchronously until they are fully opened. Further, since the damper 34 is provided between the first cover 31 and the inner tube 3 , when the user releases the button 311 , the first cover 31 and the second cover 32 can be opened synchronously and slowly.

When the first cover 31 and the second cover 32 are closed from the open state shown in FIG. 2 , the user manually presses the first cover 31 to rotate the first cover 31 in a closing direction. The rotating first cover body 31 drives the second cover body 32 to rotate synchronously in the direction of closing through the linkage mechanism 33 . When the first cover 31 rotates to a position where it cannot continue to rotate, the user releases the first cover 31 . At this time, the hooks 312, 313 can be respectively locked into the slots 321, 322, and a "click" sound will be made when locked, confirming that the first cover 31 and the second cover 32 are locked. Further, since the damper 34 is arranged between the first cover 31 and the inner tube 3, when the user presses the first cover 31, the rotation speed of the first cover 31 and the second cover 32 is relatively slow, so as not to A violent collision or injury to the user's hand may occur.

It should be noted that, in order to prevent the user from injuring his hand during closing the cover, the linkage mechanism 33 is set so that the inner cylinder cover can be closed normally only after the first cover 31 is pressed first; if the second cover 32 is pressed first, the first cover will 31 also can rotate under the effect of linkage mechanism 33, but can't close the cover because of leaving the gap between the first cover body 31.

Those skilled in the art can understand that, in the preferred technical solution of the present invention, by providing a linkage mechanism 33 between the first cover 31 and the second cover 32, the first cover 31 and the second cover 32 Can be turned on or off synchronously. Specifically, the linkage mechanism 33 includes a first link 331 and a second link 332, one end of the first link 331 is fixedly connected to the first cover 31, and the other end of the first link 331 is connected to the second link 332. One end of the second connecting rod 332 is pivotally connected to the second cover 32, and the first connecting rod 331 and the second connecting rod 332 are pivotally connected to each other, so that the first cover 31 and the second cover The bodies 32 are able to rotate synchronously in opposite directions. Therefore, compared with the electric linkage mechanism in the prior art, the linkage mechanism 33 of the present invention is simpler in structure and lower in cost.

Further, by setting the damper 33 between the first cover 31 and the inner cylinder 3, the rotation speed of the first cover 31 and the second cover 32 can be effectively slowed down, and the first cover 31 and the second cover are avoided. The body 32 makes noise when it collides with each other or the inner cylinder 3 due to too fast rotation, and simultaneously avoids the problem that the first cover body 31 and the second cover body 32 hurt the user due to too fast rotation, thereby effectively improving the safety of the user. Use experience.
