The outside of outer tube 311 is arranged in the motor switch 40 of driving motor, and motor switch 40 is common triggering manually Switch, including switch and reversal switch are rotated forward, it is concatenated by drive circuit board and power supply, the driving motor at the reading stand back side Circuit loop.Motor switch 40 controls switching on and off for the power supply of motor, controls the starting of driving motor, shuts down and turn Dynamic direction, when rotating forward, are raised above, when reversion, falls downward；And then the lifting for controlling elevating lever makes adjusting rod 30 be in difference Height, to meet different needs.

As improvement project, anti-rotation groove 315 is provided on the inside of outer tube 311, the lower end outside of elevating lever 312 is provided with Anti-rotation gag lever post 316, the anti-rotation gag lever post 316 are located in the anti-rotation groove 315 of outer tube 311, prevent elevating lever 312 on work When lower mobile, rotated together with threaded 313.

The lifting adjustable cantilever reading stand of the present embodiment have base pinch, entire bracket can be fixed on it is any can It clamps on object, is not limited to desktop, the upper clip that base pinch uses clamps jointly with movable intermediate plate and lower clamping piece, wherein activity folder Piece can rotate between upper clip and lower clamping piece using bolt as fulcrum, reach fitting parallel with upper clip and realize that increase clamping is steady Qualitative effect, and pole bracket has adjusting rod, can carry out going up and down any adjusting height by driving motor, make reading face At a distance from plate is kept between user, is promoted and be applicable in comfort level.

As shown in figure 4, reading stand 20 includes reading panel 21, the middle part for reading panel 21 is equipped with longitudinal groove 22, indulges It is equipped with through slot 23 to the bottom of groove 22, that slides in through slot 23 is equipped with slide plate 24, reads top, the longitudinal groove 22 of panel 21 Two sides be respectively equipped with horizontal concrete chute 25, slidably connect slidable panels respectively in horizontal concrete chute 25 and reading 21 two sides of panel 26, the left and right ends of each slidable panels 26 are respectively equipped with clamper.

Each clamper include a pair of of fixed plate 271 for being arranged on slidable panels 26 and setting two fixed plates 271 it Between pin shaft 272, each pin shaft 272 is each passed through the middle part of an arch-shaped pressing plate 273, on each arch-shaped pressing plate 273 and separate It reads and is respectively equipped with leaf spring between one end bottom of panel 21 and the upper surface of slidable panels 26.

As shown in Figure 5 and Figure 6, Damping rotation shaft 50 includes the shaft 52 that shaft covers 51, is arranged in shaft set 51, shaft 52 Including the damper portion 521 being fixed together and interconnecting piece 522；The shape of damper portion 521 is cylinder, and is threaded through and turns In the inner hole of axle sleeve 51, the surface of damper portion 521 is provided with a plurality of first protrusions 523, and the first protrusion 523 is in damper portion 521 Axial direction be uniformly distributed, in an imaginary circles, which is greater than shaft set 51 for the top of each first protrusion 523 Diameter of bore, the material of the first protrusion 523 is elastic material.

Axle sleeve and interconnecting piece are fixedly connected with the other end at the back side of reading stand and the second horizon bar respectively.Rotation is read The rotation in shaft covers of panel shaft, after reaching suitable position, the first protrusion covers resilient clamp by shaft, so as to so as to read Panel is kept in the position.

It is connected at the top of bracket 2 and interconnecting piece 522, bracket 2 drives shaft 52 to rotate by interconnecting piece 522, wherein damping effect Fruit is generated by the own resilient of the first protrusion 523, and in the present embodiment, the first protrusion 523 uses ABS plastic, but is not limited to This, can also be using other elastic materials such as polyurethane, rubber.First protrusion 523 and damper portion 521 can using just as material Matter is integrally formed production, can also be made and is integrally formed by way of injection molding or others of different materials, damper portion 521 Production can also be integrally formed using identical material with interconnecting piece 522, can also be made respectively of different materials, then It is fixed together for example, by bonding or other achievable modes that are fixedly connected.

It is needed during the inner hole that damper portion 521 is installed to shaft set 51 in advance to the first raised 523 applications effect Power makes it generate elastic deformation, and the vertical range on the vertex and 521 axis of damper portion that make the first protrusion 523 is less than shaft set 51 Inner hole radius, just can guarantee, by damper portion 521 be successfully installed to shaft set 51 inner hole in.It is used in the present embodiment Be provided with the cylinder shape groove coaxial with damper portion 521 on the end face of damper portion 521, the first protrusion 523 be internally provided with The deformation space of the connection of cylinder shape groove.Damper portion 521 and the first protrusion 523 in this way becomes hollow structure, makes the first protrusion Active force required for 523 flexible deformation becomes very low, is conducive to the installation of damper portion 521.

Go up and down adjustable cantilever reading stand use process is as follows:

Upper clip and lower clamping piece are pressed with hand, base pinch is clamped in supporting object, hand is unclamped and just realizes clamping；Then it opens Motor switch, switching on and off for the power supply of motor switch control motor, controls the starting of driving motor, shuts down and rotate Direction, when driving motor drives screw turns, screw rod will be driven on elevating lever by the internal screw thread of elevating lever lower end and be moved down It is dynamic, to realize that adjusting bracket automatic lifting makes adjusting bracket be in different height.

The spine of books is placed in longitudinal groove, pushes slidable panels that the clamper on slidable panels is made to reach books Books are fixed on clamper and are read on panel by edge, and books bottom contacts slide plate, stablize books.

User adjusts the tilt angle for reading panel, and Damping rotation shaft rotates and stops at suitable position, so that it may start Reading.Both hands have been liberated, and have been conducive to alleviate shoulder neck fatigue.

The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention Protection scope.
