Abstract

The utility model provides a reading frame which is convenient to use and not easy to damage. A spring 5 compresses a supporting leg 2 and a supporting leg seat 3, and the sizes of tooth faces of teeth of the tooth-shaped structures 6 of the compression contacting faces of the supporting leg and the supporting leg seat are different. After mounting is correct, the supporting leg 2 can be opened easily, a fastening device 4 is pressed and the supporting leg 2 can be folded. When large outer force presses a book supporting plate 1 downwards, the supporting leg 2 can be automatically folded to avoid being damaged.

Description

The reading frame

Technical field:

The utility model relates to a kind of reading frame.

Technical background:

The reading frame is used more and more now, but owing to also exist its supporting leg or insecure, or can not make book supporting board reach problems such as desired angle, be unfavorable for popularizing rapidly.

Summary of the invention:

The purpose of this utility model provide a kind of its supporting leg reasonable in design, easy to use, can make book supporting board and desktop form desired angle and non-damageable reading frame.

For achieving the above object, the supporting leg of the utility model reading frame is by rotating shaft, and fastener links to each other with supporting leg seat on being fixed in book supporting board, between fastener and supporting leg or between supporting leg seat and the fastener spring is being housed.

As modified, the pressurized contact-making surface of supporting leg and supporting leg seat is made dentalation, this dentalation can be the radiation centered by shaft axis, the two sides size of each tooth (or being teeth) is inequality, the shape of each tooth on same supporting leg or supporting leg seat is the same, do not consider outside circle and root circle, then the shape of cross section apart from the axis same distance of each tooth is identical on same supporting leg or the supporting leg seat, all is that limit of a length of side is short.The shape of the tooth between corresponding supporting leg and supporting leg seat is also corresponding.

After adopting such structure, easy and convenient when opening according to the supporting leg that required teeth direction is installed, supporting leg can draw in folding automatically and exempt from damage when running into big external force and press down book supporting board.

Description of drawings:

Fig. 1 is the side view of supporting leg two kinds of situations of position on book supporting board of the utility model reading frame.

Fig. 2 is the schematic diagram of first kind of specific embodiment of the utility model reading frame.

Fig. 3 is the schematic diagram of second kind of specific embodiment of the utility model reading frame.

The above two kinds of specific embodiment modified schematic diagrames of Fig. 4.

1 is book supporting board, the 2nd among the figure, supporting leg, the 3rd, and supporting leg seat, the 4th, fastener, the 5th, spring, the 6th, dentalation, the 7th, rotating shaft, the 8th, the book supporting board lower edge, filled arrows represents that supporting leg opens direction, hollow arrow is represented the folding direction of closing up of supporting leg.

The specific embodiment:

As Fig. 2, fastener 4 ends have outer silk, have adorned the hole (not having internal thread) of passing supporting leg 2 roots behind the spring 5 again thereon, screw in then in the silk hole on the supporting leg seat 3 that is fixed on the book supporting board, and fastener 4 herein also plays the effect of rotating shaft.

Fig. 3, rotating shaft 7 is connected on the supporting leg 2, passes in the hole (no internal thread) its supporting leg seat 3 on being fixed in book supporting board 1, loads onto spring 5 backs and screws in fastener 4.

As modified, after installing by Fig. 4, the pressurized contact-making surface between supporting leg 2 and the supporting leg seat 3 is dentalation 6, and the teeth shape of this dentalation is that the big one side of one side is little, and each teeth radiation centered by the axle center is arranged.Teeth shape on same supporting leg or the supporting leg seat is identical, and corresponding supporting leg is also corresponding with the shape of the teeth of supporting leg seat.When rotating with supporting leg more easily the direction opened as supporting leg of direction (teeth cross section by the direction of tooth top to long limit one side) supporting leg and supporting leg seat are installed.

During use, as Fig. 3, Fig. 4, press among fastener 4 or Fig. 2 and be pulled outwardly supporting leg 2 along axis, swing leg 2 can easily fold supporting leg 2 and draw in then, and is certain, also the available way that unscrews fastener 4.

Claims

One kind the reading frame, formed by book supporting board and supporting leg, it is characterized in that: supporting leg (2) links to each other with supporting leg seat (3) on being fixed in book supporting board (1) by rotating shaft (7) and fastener (4), between supporting leg (2) and fastener (4) or supporting leg seat (3) and fastener (4) spring (5) is arranged
2. reading frame according to claim 1, it is characterized by: the pressurized contact-making surface between supporting leg (2) and supporting leg seat (3) is dentalation (6), the both sides of the cross section of the teeth of this dentalation (6) are different big, as the direction that supporting leg (2) rotates when opening supporting leg (2) are installed to the direction of long limit one side with tooth top.
