Abstract
The invention relates to a stretchable fixed book end, which comprises two side baffle plates and connecting plates which are respectively arranged on the back part of each baffle plate and vertically connected with the baffle plates; a retractable chain is arranged on the back part of each baffle plate, an upper chain hole and a lower chain hole on two ends of the retractable chain are respectively connected with an upper positioning point of the connecting plate and a slide-way below the connecting plate; and a soleplate is arranged on the lower end of each baffle plate, and the soleplate is bent inwards to be vertically connected with the baffle plates. The stretchable fixed book end has the beneficial effects of simplicity in structure, convenience in operation and strong firmness.
Description
(1) technical field
The present invention relates to a study article, particularly the fixing book end of a kind of scalability.
(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, and easily the landing books need frequent putting in order, waste time and energy, and affect work and study.
(3) summary of the invention
The present invention is in order to remedy the deficiency of existing situation, provide a kind of can free-extension, the fixing scalability in optional position is book end fixedly.
The present invention is achieved through the following technical solutions:
Scalability of the present invention 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.
Scalability of the present invention 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, is the blanking hole of flexible chain 2 chain sheets.
Scalability of the present invention 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 in twos midpoint crossing location forms; Upper 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 connected in the slideway 8 by positioning screw rod 7, the chain hole of screw 9 below flexible chain 2 end points, location.
The invention has the beneficial effects as follows, simple structure, economical and practical, easy to operate, steadiness is strong.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present invention, and Fig. 2 is rearview of the present invention.
Among the figure, anchor point on 1,2 flexible chains, 3 connecting plates, 4 baffle plates, 5 spaces, 6 base plates, 7 positioning screw rods, 8 slideways, 9 location screws.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
Scalability of the present invention 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 in twos midpoint crossing connection end point interconnection forms; Upper 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 connected in the slideway 8 by positioning screw rod 7, the chain hole of screw 9 below flexible chain 2 end points, location.
Operation principle of the present invention: when inwardly promoting two baffle plates 4 with hand, rotate at upper anchor point 1 place in chain hole above flexible chain 2 two ends, following chain hole with positioning screw rod 7, location screw 9 along slideway 8 down slidings, flexible chain 2 inwardly shrinks, and the distance between two baffle plates shortens.When pulling out two baffle plates 4, the chain hole below flexible chain 2 end points and positioning screw rod 7, location screw 9, along slideway 8 upward slidings, flexible chain 2 outwards extends, and the distance between two baffle plates is elongated.When the distance between two baffle plates reaches requirement, fastening location screw 9 makes the chain hole below flexible chain 2 end points be fixed on certain position of slideway 8 flexible chain 2 locked not flexibles, then 4 distances of two baffle plates are locked, finished the adjustment process of two baffle spacings.
