Description

A kind of portable extension type folds reading-rack
Technical field
The utility model relates to technical field of stationery, is specifically related to a kind of reading-rack.
Background technology
Present existing reading-rack design is on the market complicated and practicality is strong, and jointly form mainly with flat board and support, integral coherence is poor, and it is large to take up room, and causes waste spatially and not Portable belt and use.
Utility model content
The purpose of this utility model is to provide a kind of portable extension type and folds reading-rack, can stretch and fold, and takes up room seldom, save space greatly, be easy to carry when having folded.
For achieving the above object, the technical solution adopted in the utility model is: a kind of portable extension type folds reading-rack, comprises two frame legs and two hack lever telescopic arms; Article two, connected by jointed shaft between frame leg; Article two, pass through gemel connection between hack lever telescopic arm; Hack lever telescopic arm is vertically fixed on frame leg by jointed shaft.
Described hack lever telescopic arm is made up of three sections of telescopic tubes.
Described frame leg is made up of two sections of telescopic tubes.
The far-end of frame leg is provided with clamp, and described clamp is connected by jointed shaft with frame leg.
Portable extension type of the present utility model folds reading-rack, whole device simple structure but practicality is extremely strong, can, according to books size free-extension, facilitate reading public to place books, in addition also can as the placing rack of panel computer and smart mobile phone, simultaneously easy to carry, save space.

Fig. 1 is the structural representation that portable extension type of the present utility model folds reading-rack;
Fig. 2 is the schematic diagram of the clamp on frame leg;
Fig. 3 is that portable extension type of the present utility model folds reading-rack folded state schematic diagram;
Fig. 4 is that portable extension type of the present utility model folds reading-rack using state schematic diagram.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of portable extension type folds reading-rack, comprises two frame legs and two hack lever telescopic arms; Article two, connected by jointed shaft between frame leg; Article two, connected by hinge 5 between hack lever telescopic arm; Hack lever telescopic arm is vertically fixed on frame leg by jointed shaft 4.Hack lever telescopic arm is made up of three sections of telescopic tubes, and hack lever telescopic arm is nested in for the 3rd section 1 in hack lever telescopic arm second segment 2, and hack lever telescopic arm second segment 2 is nested in hack lever telescopic arm first paragraph 3; Frame leg is made up of two sections of telescopic tubes, and frame leg second segment 8 is nested in frame leg first paragraph 7.At the far-end of frame leg second segment 8, be provided with clamp 6, clamp 6 is hinged by jointed shaft with frame leg second segment, clamp entirety is embedded in the groove of frame leg second segment far-end, during use, is rotated up by clamp, the bottom of books can be blocked, play fixing effect.
Hack lever telescopic arm first segment length 10 centimetres, the second segment length 10 centimetres, the 3rd segment length 8 centimetres, in order to ensure the 3rd section, second segment telescopic arm shrink successively come time can embed within first paragraph; Hack lever entirety is divided into left and right two parts, fixes, freely can fold from 0 degree to 180 degree two hack lever telescopic arm first paragraph peripheries with small-sized hinge; Frame leg is made up of two sections of telescopic tubes, the first segment length 10 centimetres, the second segment length 5 centimetres, and two frame legs are fixed on bottom two hack lever telescopic arms respectively by jointed shaft.
Whole device is made up of aluminium alloy, adapts to intensity large, can place the books of different size when opening.Not used time at ordinary times, hack lever telescopic arm and frame leg telescopic arm are amounted to into respectively most short status, close by hack lever telescopic arm, hack lever telescopic arm the 3rd section, second segment press within hack lever telescopic arm first paragraph successively, close the clamp on closed shelves leg second segment, are pressed in by frame leg second segment within frame leg first paragraph, frame leg first paragraph is rotated to the position that overlaps with hack lever telescopic arm first paragraph, as shown in Figure 3, fold up by it, not only easy to carry but also save space.As shown in Figure 4, during use, frame leg first paragraph and hack lever telescopic arm first paragraph are rotated and is split into about 90 degree, according to books size, pull out hack lever telescopic arm second segment or the 3rd section from hack lever telescopic arm respectively.Fixed by hinge between two hack lever telescopic arms simultaneously, angle can change according to the large freedom in minor affairs of books by 0 degree to 180 degree, frame leg also can according to books size unrestricted choice pull-out second segment or closed second segment, the superincumbent books page number of placement can block by the clamp of pull-out frame leg second segment, the page address portions of residence reading nationality can not be blocked again simultaneously, clamp is not pressed in the groove of frame leg second segment by the used time, and clamp can just in time embed wherein.
