Along with the rotation of apron 3 and display 2, accomodate display 2 in the casing, apron 3 lid is located casing 1 upper side back, and the one side homoenergetic that sponge piece 8 was close to each other all can the butt in display 2. In addition, when in use, the sponge block 8 can be detached to wipe the display 2, and the replacement of the sponge block 8 can be facilitated.
The implementation principle of the embodiment is as follows: when the ball plunger type driving shaft is used, the driving shaft 6 slides through the knob 65, so that the spline sleeve 61 at one end of the driving shaft 6 is mutually inserted with the spline shaft 52, at the moment, the ball head part of the ball plunger 7 can also be inserted into the first annular groove 63, the driving shaft 6 is positioned at the moment, and then the knob 65 is rotated, so that the rotating shaft 5 fixedly connected with the spline shaft 52 can be driven to rotate; firstly, rotating a rotating shaft 5 can drive two worms 51 of a cover rotating shaft 5 to synchronously rotate, and further can drive two corresponding worm wheel rings 41 to synchronously rotate, and can drive a display 2 and an inner ratchet ring 42 at one end of a cover plate 3 to synchronously rotate, because the tooth directions of the inner ratchet ring 42 at the same end of the display 2 and the cover plate 3 are opposite, when the inner ratchet ring 42 at one end of the cover plate 3 is matched with a pawl 43 to drive the cover plate 3 to rotate corresponding to a supporting shaft 4, the pawl 43 of the supporting shaft 4 of the display 2 at the same end of a shell 1 is not matched with the corresponding inner ratchet ring 42, therefore, the inner ratchet ring 42 at one end of the display 2 idles and does not drive the corresponding supporting shaft 4 to rotate, and the directions of the ratchets of the inner ratchet rings 42 on the supporting shafts 4 at two ends of the cover plate 3 are also opposite, so that the supporting shaft 4 at the other end of the cover plate, the cover plate 3 can rotate through the rotation of the supporting shaft 4 at one end, so as to realize the opening of the upper side of the shell 1, then the rotating shaft 5 is reversed, the cover plate 3 stops rotating, the pawl 43 of the supporting shaft 4 of the cover plate 3 in the adapting process is disengaged from the corresponding inner ratchet ring 42, the inner ratchet ring 42 of the cover plate 3 at the same end of the rotating shaft 5 idles, and a pawl 43 of a support shaft 4 of the monitor 2 located at the same end of the rotation shaft 5 is fitted with the corresponding inner ratchet ring 42 to drive the support shaft 4 to rotate, and as such, since the inner ratchet rings 42 at both ends of the monitor 2 are opposite in tooth direction, the support shaft 4 at the other end of the monitor 2 is not fitted to the corresponding inner ratchet ring 42, and further, can drive display 2 through the back shaft 4 of 2 one ends of display and rotate to make display 2 rotate to vertical state, convenient to use.
When the display needs to be retracted into the housing 1, the driving shaft 6 is slid by the knob 65, the spline housing 61 at the end of the driving shaft 6 is separated from the spline shaft 52, and the bevel gear four 62 at the middle of the driving shaft 6 is engaged with the bevel gear three 542, at this time, the ball head of the ball plunger 7 can also be inserted into the second annular groove 64, so as to complete the positioning of the driving shaft 6, then the knob 65 is rotated to drive the driven shaft 54 to rotate by the driving shaft 6, so as to drive the rotating shaft 5 fixedly connected with the bevel gear one 53 to rotate by engaging the bevel gear two 541 with the bevel gear one 53, then the two worms 51 are driven to rotate by the rotating shaft 5, and at the same time, the two inner worm rings 41 are driven to rotate, and further the two inner ratchet rings 42 are driven to rotate, and the supporting shaft 4 of the display 2 can be driven to rotate by the pawls 43 of, in the same way, the back shaft 4 of the other end of the display 2 is not matched with the corresponding inner ratchet ring 42, the back shaft 4 of the cover plate 3 at the same end of the shell 1 is also not matched with the corresponding inner ratchet ring 42, only the display 2 rotates, the display 2 is recovered into the shell 1, then the rotating shaft 5 is reversed, the cover plate 3 is driven to rotate in the same way, the cover and the upper side of the shell 1 are covered, and the storage of the display 2 can be completed.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
