Description
Technical field
This utility model relates to a kind of contractility book end, belongs to study article technical field.
Background technology
Student's lessons are heavy, books are more, not only want the books of amplification quantity in table hole, also the book information of amplification quantity is may require that on desktop, this is accomplished by the textbook on book end arranging desktop, because it is frequent that student takes books, if using common book end, after taking out textbook, the books clamped by book end will tilt because of the appearance in space, thus book end is produced bigger lateral pressure, cause book end spacing to expand further even to tumble, although occurring in that now and using spring to adjust the new style book stand of book end spacing between book end, but do not take into account the friction between spring contraction book end to be overcome and desktop, and probably because unbalance stress produces or rollover during book end distance reduces, the type book end is because of the restriction of spring operating distance simultaneously, book end is automatically adjusted and is limited in scope.
Summary of the invention
This utility model is in order to make up the defect of prior art, it is provided that a kind of book end moves middle the resistance more steady and automatic wider array of new style book stand of adjusting range less, mobile.
This utility model is achieved by the following technical solution:
nullA kind of contractility book end，It is characterized by: described book end includes base plate and two gripper shoes，Described base plate interior is provided with cavity，Base plate center of top is prolonged floor length direction and is had groove，Said two gripper shoe is perpendicular to plate top surface，One of them gripper shoe is fixing with one end, floor length direction to be connected，For fixed support plate，Another gripper shoe is slidably connected with base plate，For movable supporting plate，Described movable supporting plate includes supporting surface、Connecting plate and sliding bottom，Sliding bottom is positioned at base plate interior cavity，Described connecting plate connects supporting surface and sliding bottom through groove is fixing，Described sliding bottom and base plate bottom surface、Column bearing it is respectively arranged with between end face，Described column bearing is axially perpendicular to the sliding bottom direction of motion，And column bearing central rotating shaft is fixedly connected on sidewall of the bottom plate，Described floor length direction has groove on two side，It is provided with stopper slot on described sidewall groove，One rod member passes sidewall groove，And sidewall groove length direction can be prolonged move，Can also pass through stopper slot，Connect on described rod member and have spring one end，The described spring other end connects the sliding bottom of movable supporting plate.
Position-limiting action due to two rows column bearing, sliding bottom can only be parallel to plate top surface motion, and sliding bottom is when moving between column bearing, moving resistance is little, because the restriction effect of groove, sliding bottom can only prolong the motion of groove length direction, by adjusting the position of rod member, the sphere of action of spring can be adjusted, and then adjust the clamping range of book end, due to the self-locking action of book end structure, books clamped by book end are 0 to book end integral level direction active force, can effectively prevent book end from toppling over.
In order to increase the stationarity of book end movable supporting plate motion, this book end base plate interior cavity inner spring and column bearing all use even numbers, and prolong the symmetrical distribution of groove width of base plate top.
In order to prevent book end from sliding on the table, anti-slip tank can be set in base plate bottom surface or increase the roughness of base plate bottom surface.
The beneficial effects of the utility model are: in this book end movable supporting plate moving process, resistance is less, mobile more steady, and adjusting range is wider automatically.
Below in conjunction with the accompanying drawings this utility model is further described.

Accompanying drawing 1 is this utility model structural representation.
Accompanying drawing 2 is this utility model sectional side elevation.
Accompanying drawing 3 is movable supporting plate schematic diagram.

Detailed description of the invention
nullSuch as Fig. 1、Fig. 2、Described in the utility model a kind of contractility book end shown in Fig. 3，Including base plate 1、Movable supporting plate 5、Fixed support plate 6，Described base plate 1 is internal cavity 104，The end 1 center of top is prolonged floor length direction and is had groove 103，Gripper shoe 6 is fixing with base plate 1 length direction one end to be connected，Movable supporting plate 5 is slidably connected with base plate 1，Movable supporting plate 5 includes supporting surface 501、Connecting plate 502 and sliding bottom 503，Sliding bottom 503 is positioned at cavity 104，Described connecting plate 502 connects supporting surface 501 and sliding bottom 503 through groove 103 is fixing，Described sliding bottom 503 can prolong groove 103 length direction and move，Sliding bottom 503 and base plate 1 bottom surface 106、Column bearing 4 it is respectively arranged with between end face 105，Described column bearing 4 is axially perpendicular to sliding bottom 503 direction of motion，And column bearing 4 central rotating shaft is fixedly connected on base plate 1 sidewall，Base plate 1 length direction has groove 101 on two side，Stopper slot 102 it is provided with on groove 101，Rod member 2 is through groove 101，And rod member 2 can prolong groove 101 length direction and move，Can also pass through stopper slot 102，Rod member 2 connects spring 3 one end，Spring 3 other end connects sliding bottom 503.
By adjusting rod member 2 in the position of stopper slot 102, the sphere of action of spring 3 can be adjusted, and then adjust the clamping range of movable supporting plate 5, by column bearing 4, the position-limiting action of groove 103, movable supporting plate 5 is made to be only capable of prolonging the motion of groove 103 length direction, run more steady, and due to the effect of column bearing 4 so that the movable supporting plate 5 resistance in moving process significantly reduces.
During use, being placed in suitable stopper slot 102 by rod member 2 according to the gross thickness of existing book information, during picking and placeing books, movable supporting plate 5 is automatic adjusting position under the effect of spring 4, simple to operation.
