Description
Technical Field
The utility model relates to a library management technology field specifically is a synchronous telescopic machanism of books machine of checing.
Background
At present, due to the development of informatization, book collecting devices are arranged in most public places, and various information in the places is collected through the book collecting devices. The book collection device can adopt a traditional camera usually, and under a general condition, the demand of people for book collection can be met.
However, when books or storage condition information management needs to be performed on a large library or a large warehouse, books on a bookshelf or articles on a shelf need to be continuously collected, and obviously, the conventional book checking machine cannot perform the book or storage condition information management. In addition, the machines for book management and inventory have the problems of unstable center of gravity and easy falling when moving due to the arrangement of a relatively high camera rod for installing a plurality of cameras corresponding to the book shelf layers.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to enable the book checking machine to carry out signal acquisition on a large library or a large warehouse.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pair of book check machine's synchronous telescopic machanism, be in including base and setting frame on the base, surface mounting has first guide holder under the frame top, the second guide holder is installed on the base top, first guide holder with the second guide holder passes through the guide bar and connects, guide bar sliding connection antenna installation pole, the bottom surface of first guide holder with screw-nut is all installed on the top of second guide holder, be provided with on the screw-nut rather than complex lead screw, two the lead screw passes through the transmission shaft and connects, install power device on the transmission shaft.
When the screw rod moves back and forth, the guide seat and the guide rod are driven to move back and forth through the screw rod nut, so that the distance between the guide seat and the book shelf to be scanned can be adjusted conveniently.
Further, two optical axis supports are installed on the bottom surface of the first guide seat and the top end of the second guide seat, the optical axis supports are connected through an elastic optical axis, and the screw rod nut is sleeved on the elastic optical axis. When the screw rod nut is jacked to the optical axis support, the telescopic distance is kept unchanged, and when the telescopic distance needs to be adjusted, the elastic optical axis can be manually adjusted.
Further, the power device is a stepping motor. The stepping motor transmits power to the transmission shaft through a gear, and the transmission shaft is connected with the screw rod through the gear.
Furthermore, a supporting seat is arranged at one end, close to the transmission shaft, of the screw rod, the supporting seat is connected to the rack through a bottom plate, a through hole is formed in the bottom plate, and the transmission shaft penetrates through the through hole.
The utility model has the advantages that: when the telescopic mechanism extends outwards, the antenna mounting rod connected with the telescopic mechanism extends out to be close to a bookshelf to be scanned, and the antenna on the antenna mounting rod can be aligned with books on each layer for scanning; when the scanning work is finished, the telescopic mechanism retracts inwards, so that the space is saved, and the telescopic mechanism is convenient to move and place.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is an enlarged schematic view at A in FIG. 1;
in the figure: 1-base, 2-power device, 3-frame, 4-screw nut, 5-first guide seat, 6-guide rod, 7-screw, 8-second guide seat, 9-transmission shaft, 10-antenna installation rod, 11-elastic optical axis, 12-optical axis support, 13-support seat, 14-bottom plate and 15-through hole.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model provides a pair of synchronous telescopic machanism of book check machine, be in including base 1 and setting frame 3 on the base 1, surface mounting has first guide holder 5 under the 3 tops of frame, second guide holder 8 is installed on 1 top of base, first guide holder 5 with second guide holder 8 passes through guide bar 6 and connects, 6 sliding connection antenna installation poles 10 of guide bar, the bottom surface of first guide holder 5 with screw-nut 4 is all installed on the top of second guide holder 8, be provided with on screw-nut 4 rather than complex lead screw 7, two lead screw 7 passes through transmission shaft 9 and connects, install power device 2 on the transmission shaft 9.
When the screw rod 7 moves back and forth, the screw rod nut 4 drives the guide seat and the guide rod 6 to move back and forth, so that the distance between the guide seat and the book shelf to be scanned can be conveniently adjusted.
As shown in fig. 1 and 2, two optical axis brackets 12 are installed on the bottom surface of the first guide seat 5 and the top end of the second guide seat 8, the optical axis brackets 12 are connected through an elastic optical axis 11, and the elastic optical axis 11 is sleeved with the lead screw nut 4. When the feed screw nut 4 is pushed against the optical axis bracket 12, the telescopic distance is kept unchanged, and when the telescopic distance needs to be adjusted, the elastic optical axis 11 can be manually adjusted.
