Description
Technical field
The utility model relates to a kind of bookshelf, specifically refers to a kind of lift compression bookshelf.
Background technology
Existing library is in order to improve book capacity, generally all be configured with large-scale bookshelf, large-scale bookshelf so also brings problem to taking and placing books, particularly be placed on high-rise book to be not only difficult to see title, be difficult to take simultaneously, so people just contemplate the books carrying out taking and placing high level by station ladder, but station ladder uses very inconvenient, nor safety.
By retrieval, China Patent Publication No. is that CN 201734214 U discloses a kind of lifting book shelf facilitating taking and placing, and two bookcases are carried out liftable setting by hanging wheel by this bookshelf, solve the problems referred to above preferably.
But there is following problem in this structure:
When two bookcases put book amount different, the two weight differs greatly, therefore, it is very difficult lighter bookcase to be carried out descending operation, and after books are picked and placeed from lighter bookcase, in a free state, heavier bookcase moves up with lighter bookcase, and in this process, heavier bookcase will directly accelerate to decline with its weight, the heavier bookcase made when landing lands heavyly, causes bookcase to damage.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and provides a kind of reasonable in design, the lift compression bookshelf that two bookcase descending operations are convenient and safe.
For achieving the above object, the technical solution of the utility model includes bookcase framework, this bookcase framework includes a left side, right riser, a left side is set, the top board of a right riser upper end and left side is set, the base plate of right riser lower end, before and after in described bookcase framework, lifting is provided with the first bookcase and the second bookcase side by side, the top board of described bookcase framework is fixedly installed fixed pulley, on this fixed pulley, cross-over connection is provided with hoist cable, link with the upper end of the first bookcase and the second bookcase is fixing respectively in the two ends of this hoist cable, the base plate of described bookcase framework is fixedly installed servo deceleration motor, the output shaft of this servo deceleration motor is linkedly set with coiling wheel, the bottom of the first described bookcase is fixedly linkedly set with drag-line, the other end coiling of this drag-line is arranged on coiling wheel, flexible extension spring is fixedly installed between the bottom of described second bookcase and the base plate of bookcase framework.
By this setting, servo deceleration motor is utilized to carry out descending operation by drag-line to the first bookcase, the descending operation of the first bookcase will drive the second bookcase synchronization lifting to coordinate by hoist cable and fixed pulley, thus reduce bookcase and move difficulty, in addition, two bookcases can be made when weight differs greatly, when preventing descending operation bookcase by arranging elasticity extension spring, heavier bookcase is landed heavyly, improves the security of bookcase.
Further setting be the left riser of described bookcase framework inner face before and after be arranged with the first longitudinal left rail groove and the second left rail groove in parallel, described right riser is provided with and distinguishes the first symmetrical right guide-track groove and the second right guide-track groove mutually with the first left rail groove and the second left rail groove, the bilateral symmetry of the first described bookcase is provided with first leading convex tendon of leading with the first left rail groove and the first right guide-track groove straight skidding respectively and coordinate, the bilateral symmetry of the second described bookcase is provided with second leading convex tendon of leading with the second left rail groove and the second right guide-track groove straight skidding respectively and coordinate.By this setting, make the lifting moving of two bookcases more steadily reliable.
Further setting be described first guiding convex tendon outer face on the first uniform longitudinal register teeth groove of multiple longitudinal separation is set, the riser of described bookcase framework offers the first locking pin block installing hole, in the first described locking pin block installing hole, horizontal cross slippage is provided with the first locking pin block, the inner of the first described locking pin block and the first longitudinal register teeth groove location fit, the outer face of the second described guiding convex tendon arranges the second uniform longitudinal register teeth groove of multiple longitudinal separation, the riser of described bookcase framework offers the second locking pin block installing hole, in the second described locking pin block installing hole, horizontal cross slippage is provided with the second locking pin block, the inner of the second described locking pin block and the second longitudinal register teeth groove location fit.
By this setting, utilize the first locking pin block and the second locking pin block, the adjustable height of two bookcases can be positioned, facilitate the loading or unloading operation of books.
In sum, the utility model reasonable in design, descending operation difficulty is low, and prevents bookcase to land damage.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
