The four sectors a, d, e and g of the chain wheel disc 31 positioned at the upper part are respectively provided with a push rod assembly 4, the four sectors b, d, f and g of the chain wheel disc 31 positioned at the middle part are respectively provided with a push rod assembly 4, and the four sectors c, e, f and g of the chain wheel disc 31 positioned at the lower part are respectively provided with a push rod assembly 4.

Push rod assembly 4 includes ejector pin 41 that activity alternates on sprocket 31 quotation, and the one side end that ejector pin 41 is located sprocket 31 and faces support 2 is fixed with backing plate 43, and is connected with spring 44 between backing plate 43 and the quotation of sprocket 31, and spacing bulge loop 42 is fixed to the one side that ejector pin 41 is located sprocket 31 and faces book placing groove 7.

Two baffle 8 are located 1 inside sides of support body and are fixed with limit baffle 6, and limit baffle 6 carries out spacing avoiding putting book groove 7 and pushes away 1 too depths of support body to putting book groove 7, and is same position department that corresponds with baffle 8 on the 1 bottom plate of support body also is fixed with limit baffle 6, and spout 81 has all been seted up to the upper surface of two baffle 8 and the bottom plate upper surface of support body 1, and the bottom surface sliding connection who puts book groove 7 is in spout 81, and the side limit of the bottom plate front end of putting book groove 7 is fixed with bounding wall 71, and bounding wall 71 prevents books extroversion the one hand, plays the guard action, is used for on the one hand resetting putting book groove 7, and is simple structure, and convenient operation.

The working principle of the invention is as follows: a wireless WIFI module 12 on a control mainboard 13 inside the control box is connected with an indoor local area network through an indoor wireless router, a wireless module on the mobile phone is also connected with the indoor local area network through the wireless router, the mobile phone is operated through APP software installed on the mobile phone, and the mobile phone controls the starting and stopping of a motor 11 and the power on and off of an air cylinder 15 through the control mainboard 13;

when needing a certain or several book slots 7 to be put and pushing out, control panel 13 control motor 11 circular telegram, drive three sprocket dish 31 synchronous rotation through the transmission of chain 9 for the symmetry line of the sector that corresponds coincides with the vertical axis of sprocket dish 31, and start cylinder 15, piston rod promote support 2 and push pedal 5 synchronous motion exert the effect to push rod assembly 4, push out corresponding book slot 7, for example: when any one of the upper, middle and lower book placing grooves 7 needs to be pushed out, the starting motor 11 drives the chain wheel disc 31 to rotate so that the symmetry line of the sector area a or b or c of the chain wheel disc 31 coincides with the vertical central axis of the chain wheel disc 31, the motor 11 stops, the air cylinder 15 is started, the piston rod of the air cylinder 15 pushes the push plate 5 on the support 2 to push the push rod assembly 4 on the sector area a or b or c, and the motion process of the push rod assembly 4 is as follows:

when the push plate 5 contacts the backing plate 43, a force pointing to the book placing groove 7 is applied to the backing plate 43, so that the backing plate 43 drives the ejector rod 41 to approach the back plate of the book placing groove 7, the spring 44 is compressed, when the ejector rod 41 contacts the back plate of the book placing groove 7, a thrust force is applied to the book placing groove 7, and along with the continuous movement of the push plate 5, the ejector rod 41 extends the book placing groove 7 outwards from the frame body 1 along the sliding groove 81 until the push plate 5 moves to an extreme limit position, the air cylinder 15 is powered off and reset, the backing plate 43 is not stressed, no force is applied to the spring 44, the spring 44 is reset and extends, and a reverse force is applied to the backing plate;

when a book is taken down from the book placing groove 7 or placed in the book placing groove 7, the enclosing plate 71 is pushed to move the book placing groove 7 into the frame body 1 along the sliding groove 81;

when any two book placing grooves 7 of the upper, middle and lower three book placing grooves 7 are required to be pushed out simultaneously, the control panel 13 controls the motor 11 to be electrified, and the chain 9 drives the three chain wheel discs 31 to synchronously rotate, so that the symmetry line of the sector d, e or f coincides with the vertical central axis of the chain wheel discs 31, for example: the upper book placing groove 7 and the middle book placing groove 7 need to be pushed out simultaneously, only the symmetric line of the d-sector area of the chain wheel disc 31 needs to be overlapped with the vertical central axis of the chain wheel disc 31, the air cylinder 15 is started to push the support 2 and the push plate 5 to apply thrust to the push rod assemblies 4 of the d-sector area on the upper chain wheel disc 31 and the lower chain wheel disc 31, the upper book placing groove 7 and the middle book placing groove 7 can be pushed out simultaneously, the push plate 5 cannot push the lower book placing groove 7 out due to the fact that the d-sector area of the lower chain wheel disc 31 does not have a push rod assembly, the same symmetric line of the e-sector area is overlapped with the vertical central axis of the chain wheel disc 31, the upper book placing groove 7 and the lower book placing groove 7 can be pushed out simultaneously, and the symmetric line of the f;

when the upper, middle and lower three book slots 7 need to be pushed out simultaneously, the control panel 13 controls the motor 11 to be electrified, and the three chain wheel discs 31 are driven to rotate synchronously through the transmission of the chain 9, so that the symmetry line of the g sector area coincides with the vertical central axis of the chain wheel discs 31.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
