CONCRETE IMPLEMENTATION
[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0021] The utility model provides a kind of telescopic book stand as shown in Figures 1-4 It is provided with telescopic support 2 between two bases 1, the top end of base 1 is fixedly connected with support rod 3, by pulling two bases 1, telescopic support 2 can be telescoped automatically, so that different number of books can be placed.
[0022] The top end of base 1 is provided with adjusting mechanism 4.
[0023] Further, adjusting mechanism 4 includes rotating plate 41, support plate 42, limiting rod 43 and elastic positioning assembly 44, rotating plate 41 is rotatably connected to the top end of base 1 by rotating shaft, the top end of base 1 is provided with groove, support plate 42 is slidably connected with the inner cavity of groove, limiting rod 43 is fixedly connected to the bottom end of rotating plate 41, the top end of support plate 42 is provided with limiting slot, limiting rod 43 is slidably connected with the inner cavity of limiting slot, the top end of support rod 3 is provided with elastic slot, elastic positioning assembly 44 is located in the inside of elastic slot, elastic positioning assembly 44 cooperates with rotating plate 41, by releasing the positioning of rotating plate 41 by elastic positioning assembly 44, rotating plate 41 can be rotated, and limiting rod 43 is slid from arc slot to straight slot, at this time, support plate 42 can be pushed, so that support plate 42 slides out and exposes groove, at this time, support plate 42 plays a stabilizing role, the inner cavity of groove can place books, so that after two rotating plates 41 are spliced together, the whole book stand can become book reading stand, two-in-one, and does not occupy large area of desktop, so as to facilitate selective use.
[0024] Further, the elastic positioning assembly 44 comprises a fixed plate 441, a fixed rod 442, a connecting rod 443, a pressing plate 444 and a compression spring 445. The pressing plate 444 is located in the elastic groove. One end of the connecting rod 443 is fixedly connected with the fixed plate 441, and the other end of the connecting rod 443 is fixedly connected with the pressing plate 444. The compression spring 445 is sleeved on the outside of the connecting rod 443. The fixed rod 442 is fixedly connected with the bottom end of the fixed plate 441. The top end of the rotating plate 41 is provided with a fixed hole. The fixed rod 442 is slidably inserted into the inner cavity of the fixed hole. One end of the compression spring 445 is fixedly connected with the pressing plate 444, and the other end of the compression spring 445 is fixedly connected with the top end of the inner wall of the elastic groove. The cross section of the pressing plate 444 is square. The compression spring 445 is always in a compressed state, so that the pressing plate 444 can provide an elastic force for the connecting rod 443, so that the fixed plate 441 fixedly connected with the top end of the connecting rod 443 can tightly abut against the top end of the supporting rod 3, and the fixed rod 442 can be stably inserted into the fixed hole of the rotating plate 41, so that the rotating plate 41 can be positioned.
[0025] Further, the limiting groove is composed of an arc-shaped groove and a straight groove. The cross section of the supporting plate 42 is L-shaped, and the cross section of the limiting rod 43 is T-shaped. When the rotating plate 41 is released from the fixing and is rotated through the rotating shaft, the limiting rod 43 can first slide in the arc-shaped groove, and then slide in the straight groove when the rotating plate 41 is rotated by 90°. At this time, the limiting rod 43 no longer limits the supporting plate 42, so that the supporting plate 42 can slide horizontally through the straight groove, thereby increasing the contact area of the base 1, and facilitating the splicing of the two rotating plates 41 to form a book stand.
[0026] Further, one of the rotating plates 41 is fixedly connected with a connecting plate 5, and the other rotating plate 41 is provided with a connecting groove. The connecting plate 5 is matched with the connecting groove. When the two rotating plates 41 are rotated by 90°, the connecting plate 5 and the connecting groove are inserted into each other, so that the two rotating plates 41 are spliced into a whole plate, thereby facilitating the placement of books in the grooves and on the two rotating plates 41.
[0027] Further, the base 1 and the bottom end of the supporting plate 42 are fixedly connected with rubber pads 6. The outer wall of the rubber pad 6 is provided with anti-skid textures. The setting of the rubber pad 6 increases the friction between the base 1, the supporting plate 42 and the table top, so that the base 1 and the supporting plate 42 can be stably placed on the table top when used as a book stand or a book reading stand.
[0028] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
