Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The library bookshelf as shown in fig. 1 and 2 comprises a plurality of transverse partition plates 1 and book ends 2 arranged on the partition plates 1, wherein sliding grooves 3 are formed in the partition plates 1, and sliding blocks 4 corresponding to the sliding grooves 3 are arranged at the bottoms of the book ends 2.

The two groups of the sliding blocks 4 are arranged in bilateral symmetry, each group of the sliding blocks 4 comprises two U-shaped sliding blocks 401, the side faces of the two U-shaped sliding blocks 401 are connected to the bottom of the book stand 2, the two U-shaped sliding blocks 401 are arranged in a back-to-back mode, openings of the two U-shaped sliding blocks 401 face to two sides respectively, and a gap is reserved between the two U-shaped sliding blocks 401; the sliding chute 3 is of an I-shaped structure, and the side walls of the U-shaped sliding block 401 are correspondingly buckled into the upper part and the lower part of the sliding chute 3 respectively; and a locking device 5 is arranged at the gap between the U-shaped sliding blocks 401.

The locking device 5 comprises inclined teeth 501; a slideway 502 is arranged on the side surface of the book stand 1, and the slideway 502 corresponds to a gap between the two U-shaped sliding blocks 401; the slide ways 502 corresponding to the two groups of slide blocks 4 are internally provided with inverted U-shaped connecting arms 503, and the two inclined teeth 501 are respectively connected to two ends of the connecting arms 503; the helical teeth 501 incline towards one side provided with the slide ways 502, the central part of the bottom in the chute 3 is provided with a helical rack 504, the helical rack 504 corresponds to the helical teeth 501, and the inclination direction is opposite to the inclination direction of the helical teeth 501.

Reinforcing ribs 505 obliquely connected to the U-shaped sliding block 401 are arranged on two sides of the sliding way 502.

The height of the helical teeth 501 is one third of the height of the sliding chute 3, and the height of the helical rack 504 is one third of the height of the sliding chute 3.

The inclined angles of the helical teeth 501 and the helical rack 504 are both 30 degrees.

As shown in FIG. 3, the upper surface and the side surface of the inner wall of the U-shaped slider 401 are respectively provided with spherical protrusions 6 which are uniformly distributed.

Set up the slider to corresponding U type slider structure, be for the convenience of locking device's installation on the one hand, on the other hand, U type slider lies in the spout complex in, and the rack diagonal of spout bottom carries on spacingly respectively to two U type sliders from the middle part, makes the slider stronger with the cooperation stability of spout.

The connecting arm, the helical teeth and the helical rack are structurally characterized in that the helical teeth and the helical rack are separated by lifting the connecting arm, the connecting arm is put down, and the helical teeth and the helical rack are matched to realize locking, which is similar to the working principle of a ratchet; the helical teeth and the helical racks are respectively set to be one third of the sliding grooves, the locking compactness is ensured, and unstable factors caused by over loose structure are avoided. Meanwhile, the inclination angles of the helical teeth and the helical racks are set to be thirty degrees, if the inclination angle is too large, a large force needs to be consumed in the sliding process to slide, and if the inclination angle is too small, the locking of the helical teeth and the helical racks is not firm enough.

The spherical bulge arranged in the U-shaped sliding block changes the matching of the U-shaped sliding block and the sliding chute from surface-to-surface sliding to point-to-surface sliding, and the sliding flexibility can be increased to a certain extent.

In the using process, a book is placed at the front part of the book stand, the book stand is pushed to move forwards from the rear side, due to the left and right of the helical teeth and the helical rack, the book stand can be pushed to a proper position easily without pulling the connecting arm, the process is one-way, and if the connecting arm is not lifted upwards, the book stand is locked in the backward direction. When the book stand needs to be opened, the connecting arm is lifted by one hand, the inclined teeth and the inclined rack are locked and opened, the book stand can slide backwards, and the using effect is good.
