Abstract

The utility model discloses an adjustable and retractable reading-rack. A tray slope plate (13) is connected with a bottom plate (2) through a hinge (14). A movable bracket (4) which is used to support the tray slope plate (13) is fixed on the bottom plate (2) through a support block (3). The tray slope plate (13) is provided with two slip plates (6), (11) inside which can extend and shrink in transverse direction right and left, and a slip plate (8) which can extend and shrinks in longitudinal direction up and down. The area of the tray slope plate (13) can be changed through the left-right transverse movement and the up-down longitudinal movement of the slip plates when the slip plates are pushed by hand. The inclination angle of the tray slope plate (13) can be changed through the rotation of the movable bracket (4). Therefore, the utility model can keep book pages smooth. The front face of the tray slope plate (13) keeps vertical to sight lines. The utility model can protect vision, and is suitable for reading various books with different specifications.

Description

Adjustable expansion reading-rack

The utility model relates to a kind of telescopic adjustment reading frame.

Existing reading frame, it relies on the swash plate area to fix, and can not change because of the size of book, and is not too convenient during use.

The purpose of this utility model provides a kind of big or small changeable telescopic adjustment reading frame that relies on the swash plate area with book.

The utility model comprises the support swash plate that is provided with hinge seat and several piece angle-regulating block, be provided with the base plate of hinge seat and two pieces and be contained in the travel(l)ing rest that props up on the piece, it is characterized in that relying on swash plate by panel, the dividing plate I, the dividing plate II, two left and right sides transversal stretching slide plates, a longitudinal extension slide plate is formed, the filler rod of two projectioies is housed in the both sides of dividing plate I, left and right sides transversal stretching slide plate is contained between the filler rod of dividing plate I, the filler rod of two projectioies is housed in the both sides of dividing plate II, the longitudinal extension slide plate is contained between the filler rod of dividing plate II, panel and the dividing plate II that the dividing plate I of two left and right sides transversal stretching slide plates is housed and a longitudinal extension slide plate is housed are superposeed successively, stick with glue the agent be adhesively fixed.

Above-described telescopic adjustment reading frame; by pull two left and right sides transversal stretching slide plates and longitudinal extension slide plate do left and right sides transverse movement and up and down lengthwise movement change the area that relies on swash plate; by rotating travel(l)ing rest and different angle-regulating block contacts; change the inclination angle that relies on swash plate; therefore; telescopic adjustment reading frame has length and width and the inclination angle according to the size of book and both view angle adjustment support swash plate; written smooth to guarantee; make and rely on swash plate vertical with sight line; vision protection, and be adapted to read the books of various different sizes.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a back view of the present utility model;

Fig. 2 is a front elevation of the present utility model;

Fig. 3 is the structure chart that the dividing plate I of filler rod is housed of the present utility model;

Fig. 4 is the structure chart that the dividing plate II of filler rod is housed of the present utility model.

The utility model is included in the support swash plate (13) that the back side is provided with hinge seat (5) and several piece angle-regulating block (7), be provided with the base plate (2) of hinge seat (1) and two pieces (3) and be contained in the travel(l)ing rest (4) that props up on the piece (3), rely on an end of swash plate (13) to be connected by hinge (14) with an end of base plate (2), travel(l)ing rest (4) can contact with different angle-regulating blocks (7), rely on swash plate (13) to make relative circular motion with base plate (2), one end of travel(l)ing rest (4) is contained on the piece (3), travel(l)ing rest (4) base plate (2) is relatively done the fillet motion, rotate travel(l)ing rest (4) and different angle-regulating block (7) contacts, just can change the inclination angle that relies on swash plate (13), rely on swash plate (13) by panel (9), dividing plate I (10), dividing plate II (12), two left and right sides transversal stretching slide plates (6), (11), a longitudinal extension slide plate (8) is formed, its structure is: the filler rod (15) that two projectioies are housed in the both sides of dividing plate I (10), left and right sides transversal stretching slide plate (6), (11) be contained between the filler rod (15) of dividing plate I (10), guarantee left and right sides transversal stretching slide plate (6), (11) between the filler rod (15) of dividing plate I (10), do left and right sides transverse movement, the filler rod (16) of two projectioies is housed in the both sides of dividing plate II (12), longitudinal extension slide plate (8) is contained between the filler rod (16) of dividing plate II (12), and assurance longitudinal extension slide plate (8) is done lengthwise movement up and down between the filler rod (16) of dividing plate II (12).Panel (9) and the dividing plate (12) that the dividing plate I (10) of two left and right sides transversal stretching slide plates (6), (11) is housed and a longitudinal extension slide plate (8) is housed are superposeed successively, stick with glue the agent be adhesively fixed.
