Abstract
The utility model relates to a stretchable fixed book stand. The stretchable fixed book stand comprises baffles on two sides of the book stand and connecting plates which are arranged on back portions of the baffles and perpendicularly connected with the baffles. A stretchable chain is arranged on the back portions of the baffles, an upper chain hole and a lower chain hole on two ends of the stretchable chain are respectively connected with an upper positioning point and a slide below the upper positioning point on each connecting plate, base plates are arranged on the lower ends of the baffles, and the base plates are folded inward and perpendicularly connected with the baffles. The stretchable fixed book stand has the advantages of being simple in structure, convenient to operate and strong in stability.
Description
(1) technical field
The utility model relates to a study article, and particularly a kind of scalability is book end fixedly.
(2) background technology
Traditional book end is mostly pushed down the baffle plate of both sides for the gravity that relies on book, steadiness is poor, is prone to the landing books, needs frequent putting in order, wastes time and energy, and influences work and study.
(3) utility model content
The utility model is in order to remedy the deficiency of existing situation, and providing a kind of can freely stretch, and the scalability that the optional position is fixed is book end fixedly.
The utility model is realized through following technical scheme:
The scalability of the utility model is book end fixedly, and its special character is: comprise the baffle plate 4 that is located at both sides, flexible chain 2, connecting plate 3 are positioned at the back of baffle plate 4, are connected between two baffle plates 4, and base plate 6 is positioned at inboard, baffle plate 4 lower ends and 4 vertical connections of baffle plate.
The scalability of the utility model is book end fixedly, and more economical for more compact structure, connecting plate 3 is positioned at inboard, baffle plate 4 backs and 4 vertical connections of baffle plate; Space 5 is positioned on the baffle plate 4.
The scalability of the utility model is book end fixedly, and for flexible better with fixed performance, flexible chain 2 is by some in flakes identical, and the end points interconnection of the location of midpoint crossing in twos forms; Last anchor point 1 is positioned at the upper end of connecting plate 3, and with the location, company hole above flexible chain 2 end points, slideway 8 is positioned at the below of anchor point 1, is positioned the chain hole below flexible chain 2 end points in the slideway 8 by slide bar 7 and positioner 9.
The beneficial effect of the utility model is, simple structure, and economical and practical, easy to operate, steadiness is strong.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model, and Fig. 2 is the rearview of the utility model.
Among the figure, anchor point on 1,2 flexible chains, 3 connecting plates, 4 baffle plates, 5 spaces, 6 base plates, 7 slide bars, 8 slideways, 9 positioners.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.
The scalability of the utility model is book end fixedly, comprises the baffle plate 4 that is located at both sides, and flexible chain 2, connecting plate 3 connect between two baffle plates 4 at the back of baffle plate 4, and base plate 6 is positioned at inboard, baffle plate 4 lower ends and 4 vertical connections of baffle plate.Connecting plate 3 is positioned at inboard, baffle plate 4 backs and 4 vertical connections of baffle plate; Space 5 is positioned on the baffle plate 4, is the blanking hole of flexible chain 2.Flexible chain 2 is by some in flakes identical, and midpoint crossing connection end point interconnection in twos forms; Last anchor point 1 is positioned at the upper end of connecting plate 3, and with the location, company hole above flexible chain 2 end points, slideway 8 is positioned at the below of anchor point 1, is a microscler cylindrical void, is positioned the chain hole below flexible chain 2 end points in the slideway 8 by slide bar 7 and positioner 9.
The operation principle of the utility model: when inwardly promoting two baffle plates 4 with hand; Chain hole above flexible chain 2 two ends, the rotation at last anchor point 1 place, following chain hole with slide bar 7, positioner 9 along slideway 8 to lower slider; Flexible chain 2 inwardly shrinks, and the distance between two baffle plates shortens.When outside pulling two baffle plates 4, upwards slide along slideway 8 in chain hole and slide bar 7, positioner 9 below flexible chain 2 end points, and the chain 2 that stretches outwards extends, and the distance between two baffle plates is elongated.When the distance between two baffle plates reaches requirement; Fastening positioning device 9 is fixed on certain position of slideway 8 the chain hole below flexible chain 2 end points, and flexible chain 2 is locked not flexible; Then 4 distances of two baffle plates are locked, and have accomplished the adjustment process of two baffle spacings.
Claims (3)
