Description

A kind of dual-purpose V-type book car

Technical field

A kind of dual-purpose V-type book car, is a kind of for library's books and periodicals cataloguing, the added dual-purpose books and periodicals transportation means that circulates, and more particularly, is a kind of V-type book car switching back and forth at flat truck and V-type book car of can realizing rapidly.

Background technology

The books that library works comprise into bag, the transport of bundled set, therefore need flat truck; The books and periodicals transport that library works also comprise the processing of books and periodicals cataloguing, circulate added, these needs of work can be seen the side of books and periodicals at any time, therefore need V-type book car.In general, library is all equipped with respectively flat truck and V-type book car.Realize promptly the dual-purpose V-type book car switching back and forth at flat truck and V-type book car by simple structure, can facilitate librarian to use, also can save equipment configuration expense.

Summary of the invention

The present invention seeks to realize promptly by simple structure the dual-purpose V-type book car switching back and forth at flat truck and V-type book car, can facilitate librarian to use, also can save equipment configuration expense.

1. the structure of a dual-purpose V-type book car:

(1) a dual-purpose V-type book car, is made up of handrail, cardan wheel, two-layer V-type bookcase, base plate and car body, it is characterized in that, described two-layer V-type bookcase is collapsible hinge shape, can fix V-type bookcase in 90 ° or amount to and pack up; Book car side plate has knock hole; Base plate is arranged at book car bottom.

(2) described upper strata V-type bookcase is collapsible hinge shape, and V-type bookcase long slab hinge end far away has a round sleeve, and round sleeve is enclosed within on the anchor shaft at angle on book car side plate, can be around anchor shaft free motion; V-type bookcase short slab hinge end far away has a round sleeve, and round sleeve is enclosed within on movable axis, and there is the perforate of corresponding movable axis button centre; The long slab of V-type bookcase is that hinge shape is connected with the junction of short slab, and hinge axis is positioned at V-type bookcase below.

(3) described lower floor's V-type bookcase structure is consistent with upper strata V-type bookcase, and anchor shaft is positioned at position, the same side, and lower floor's V-type bookcase is positioned under the V-type bookcase of upper strata, between two bookcases, has certain distance.

(4) in the middle of described movable axis, have button, by pressing the bracing wire of fixed position, the card cap of being combined with bracing wire that can control movable axis two ends under the effect of two ends spring is flexible.

(5) described book car side plate has knock hole, and in the time that movable axis is stuck in the knock hole on book stay limit that is positioned at anchor shaft far away, V-type bookcase is fixed V-type bookcase in 90 °; In the time that movable axis is stuck in the knock hole being positioned under anchor shaft, V-type bookcase is folded is retracted to " 1 " side word shape.

(6) described book car has tabular base plate, is positioned at the book car bottom.

(7) described both sides, book car top respective side Board position has handrail.

(8) bottom the book car described in, four jiaos have cardan wheel.

2. the using method of a dual-purpose V-type book car:

(1) while use as V-type book car, press the button on movable axis, button is under bracing wire fix shaft coordinates, drive bracing wire to overcome acting force of the spring retraction movable axis two ends card cap, when movable axis is moved to the knock hole on book stay limit of anchor shaft far away, release button, because spring resistance position device has been fixed one end of spring, spring recovers length from the other end, drive card cap to eject, block corresponding knock hole, V-type bookcase short slab and long slab shape V-type bookcase in 90 °, to upper and lower two-layerly all press after this operation, can form a two-layer V-type book car, use as V-type book car.
