The utility model content
The technical problems to be solved in the utility model provides a kind of bookrack, but the books that adjustable angle and clamping thickness do not wait help people's books of reading comfily.
Above-mentioned purpose is achieved through the following technical solutions: a kind of bookrack, it is characterized in that, comprise: base plate, two connecting plates, supporting plate, movable supporting plate, keeper and clamp assemblies, two connecting plates are located at the two side ends of base plate respectively, the front end both sides of supporting plate are connected in described connecting plate rotationally, movable supporting plate connects the back side of supporting plate rotationally, and positioning component is arranged at base plate, and clamp assemblies is connected in the front end of supporting plate.
Also comprise two fixed support plates, described two fixed support plates are located on the base plate and between two connecting plates.
The thickness sum of the height of described fixed support plate and described supporting plate equals the height of described connecting plate.
Described clamp assemblies comprises back-up block, guide rod, spring, clamping plate and nut, described back-up block is connected in the front end of described movable supporting plate, described guide rod is arranged at the two ends of back-up block, described spring housing is located at described guide rod, described clamping plate are located at guide rod and are positioned at the spring upper end, and described nut is provided with lower end of the guide rod and is positioned at the below of back-up block.
Described clamp assemblies comprises back-up block, guide rod, spring, clamping plate and nut, described back-up block is connected in the front end of described movable supporting plate, described guide rod is arranged at the two ends of back-up block, described spring housing is located at described guide rod, described plywood sleeve is located at guide rod and is positioned at the spring upper end, and described nut is provided with the guide rod upper end and is positioned at the top of clamping plate.
The utility model bookrack is realized angle adjustable by base plate, two connecting plates, supporting plate, movable supporting plate and keepers, make things convenient for the user freely to adjust according to required, connect base plates and supporting plate by two connecting plates are set, make simple and design clamp assemblies of syndeton reduced by the restriction in space.The utility model makes that by two fixed support plates of design supporting plate can not pushed down movable supporting plate when bookrack closed up, and allows both the stressed minimizing in junction.The utility model is designed to equal the height of connecting plate with the thickness sum of the height of fixed support plate and supporting plate, makes bookrack close up box of time image, and is very attractive in appearance.

Side view when Fig. 2 launches for the utility model;
Front view when Fig. 3 closes up for the utility model;
Vertical view when Fig. 4 closes up for the utility model.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model bookrack comprises: base plate 1, connecting plate 11,12, supporting plate 2, movable supporting plate 3, keeper 5, fixed support plate 13,14, clamp assemblies 4; Wherein, clamp assemblies 4 comprises back-up block 41, spring 42, guide rod 43, nut 44 and clamping plate 45.
The concrete structure of the utility model bookrack is as follows:
For convenience of description, when using bookrack, bookrack looked closely near user's be front end.Connecting plate 11,12 are connected to base plate 1 both sides, base plate 1 both sides also are respectively equipped with fixed support plate 13,14, fixed support plate 13,14 are positioned at connecting plate 11, between 12, supporting plate 2 front end both sides and connecting plate 11,12 front end flexibly connects, the height H 1 of fixed support plate and the thickness H3 sum of supporting plate equal the height H 2 of connecting plate, keeper 5 is for being provided with several rows of locating slot or the positioning convex strip on the base plate 1, movable supporting plate 3 one ends are connected in the back side of supporting plate 2 versatilely, back-up block 41 is connected in supporting plate 2 front ends, back-up block 41 two ends are provided with two guide rods 43, spring 42 is sheathed on guide rod 43, clamping plate 45 are located at guide rod 43 and are positioned at spring 42 upper ends, guide rod 43 lower ends are provided with nut 44, and nut 44 also is positioned at the below of back-up block 41, and guide rod 43 lower ends have screw thread to match with nut 44.
The use of the utility model bookrack is as follows:
When the reading books, bookrack is placed desktop, start supporting plate 2, swing movable supporting plate 3 then, put angle according to required books, the lower end of movable supporting plate 3 is placed the relevant position of keeper 5, books are opened and placed on the supporting plate 2, at this moment, supported 14 of the bottom of books withstood and clamped by clamping plate 45, avoids page to touch, and adjusts the position of nut 44 at guide rod 43 according to the thickness of books, nut 44 relative guide rods 43 move upward, just make clamping plate 45 near supporting plate 2, spring 44 is compacted, and nut 44 relative guide rods 43 move downward, under the reduction of spring 42, clamping plate 45 depart from supporting plate 2; If books are blocked up, clamping plate 45 are not made clamping action, and play the books effect of supporting.When not using the reading bookshelf, movable supporting plate 3 is put backward, and supporting plate 2 is placed in fixed support plate 13,14 tops downwards, and supporting plate 2 can not pushed down movable supporting plate 3, thereby do not increase the weight of connecting portion stressed of movable supporting plate 3 and supporting plate 2, avoid the damage of movable supporting plate and breaking of junction.Because the support of fixed support plate 13,14, supporting plate 2 is consistent with the upper surface of connecting plate 11,12, makes a bookrack picture box, and is very attractive in appearance.
