Embodiment
Describe below in conjunction with the technical scheme of accompanying drawing utility model.
An embodiment of a kind of portable support projection screen of the present utility model is shown in Fig. 1,2,3,4,5, comprise: outer cover 1, spool, curtain 2, support bar 3, tripod 4 and lifting shaft 21, described curtain 2 one ends are fixed on the lifting shaft 21, the other end is wrapped on the spool, described spool is provided with torsion spring, and described spool is installed in the outer cover 1.1 is provided with opening on the outer cover, and the link of curtain and lifting shaft 21 stretches out outside the outer cover 1, and when packing up curtain 2, lifting shaft 21 is blocked in the opening part of outer cover 1, and curtain 2 can not be entered in the outer cover 1 fully, is convenient to pull out curtain 2 and uses.Described tripod 4 is connected with support bar 3, can open during use to be supported on the ground, can merge gathering when not using.
In the present embodiment, also comprise one handle frame 5, described handle frame 5 is sheathed on the described support bar 3 and can slides up and down at support bar 3.Described handle frame 5 comprises handle 51, support 52 and spring 53, and described handle 51 is fixedlyed connected with described support 52.Spring 53 is installed in the handle 51, thereby realizes handle 51 sliding up and down on support bar 3 by compression spring 53.Described outer cover 1 and described handle frame 5 are hinged, and this jointed shaft is perpendicular to described support bar 3.Concrete, described outer cover 1 is provided with cutting ferrule 11, and described cutting ferrule 11 is hinged by rivet and described support 52.Use said structure, on the one hand, realized that outer cover 1 is connected with handle frame 5, outer cover 1 can move up and down at support bar 3 with handle frame 5 and adjust the desired position; On the other hand, outer cover 1 can be around jointed shaft 180 degree rotations.Therefore, when using projection, outer cover 1 rotates to the position vertical with support bar 3, then curtain 2 is drawn out to required height from outer cover 1, and adjusts the position of outer cover 1 by the position of moving handle frame 5 on support bar 3, can carry out projection; When not using projection, outer cover 1 rotates to the position parallel with support bar 3, has reduced spatial volume, is easy to carry.The whole operation process is simply quick, and is very convenient.
In the present embodiment, described support bar 3 inside are provided with expansion link 6, and the end that described expansion link 6 stretches out support bar 3 is provided with crown cap 61, and described top cap 61 has a groove 611, and groove 611 is used for curtain is hung over top cap 61.This expansion link 6 optional position in telescopic process can be blocked by clamping part, can adjust the required height that reaches of curtain according to the length of expansion link.
Further, it is protruding 612 that described top cap 61 is provided with card, and described outer cover 1 one ends are provided with draw-in groove 12, when not using projection, outer cover 1 and support bar 3 parallel placements, described card protruding 612 and described draw-in groove 12 clampings, thereby outer cover 1 and support bar 3 are fixed, be convenient for carrying.
In the present embodiment, described tripod 4 is connected with support bar 3 by a slip cap 7, during use, opens tripod 4 and is supported in ground, when not using, it can be merged and draw in.
Fig. 1 and Fig. 5 have showed the use of portable support projection screen of the present utility model and the structural representation of unused state respectively, and its principle of work is as follows:
When carrying out the projection use, tripod 4 opened stand on ground, outer cover 1 is rotated to the state vertical with support bar 3, pull out and be hung on curtain 2 on the top cap 61 of expansion link 6 from outer cover 1 then, the expansion link 6 that upwards stretches makes curtain 2 reach required height, and fix handle frame 5 adjust the position of outer cover 1 in the position on the support bar 3 by moving handle frame 5 after, can carry out projection;
When not using projection, expansion link 6 is retracted to downwards in the support bar 3, curtain 2 is recycled in the outer cover 1 by the torsion of spool torsion spring, then outer cover 1 is rotated to position with support bar 3 levels, simultaneously with draw-in groove 12 clampings of the card of top cap 61 protruding 612 with outer cover 1, close up tripod 4, integral body is portability.
Above embodiment is only in order to the explanation the technical solution of the utility model but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
