Description

Portable light reflecting and photometric plate lens

The utility model relates to a kind of device of reflective, photometry plate, the photographic accessory of a kind of portable reflective, the photometry that particularly conveniently folds.

Existing reflector needs the position of light filling to obtain uniform reflected light photograph for making the bigger subject of volume, adopts a monoblock type large-area flat-plate that is coated with reflectorized material more.For light meter provides the standard photometry plate of exposure parameter under the on-the-spot illumination, be that reflecting rate is 18% grey photometry plate, the same with reflector also is an independent photographic accessory.

The purpose of this utility model provides that a kind of combination is reflective, two kinds of functions of photometry, can fold and pull, launches to form the tabular device with same normal direction.

The utility model is like this design: what comprise pumping board and turnover panel respectively forward and backwardly decide respectively one of plate, constitute a principal reflection plate, location and pinning behind 180 ° of two principal reflection plate developments, forward and backward turnover panel and pumping board can be decided to extract out in the plate and pinned by self-locking device from corresponding, location and pinning after changeing 180 ° again between turnover panel and the pumping board, promptly constitute collapsible and pull, and launch to form and to have the tabular device of same normal direction, and be provided with handle and connect use for one-handed performance or with tripod; At its tow sides, be coated with reflecting material that reflecting rate is 90%-100% and reflecting rate and be 18% grey photometry material, selective use.

Below by expansion of the present utility model with fold process, in conjunction with the accompanying drawings, wherein:

Principle of work: will decide two blocks of principal reflection plates that plate (1) and predetermination plate (4) form by back shown in Figure 1 earlier and do 180 ° of garden Zhou Yundong expansion around hinge (7), make the superimposed position as shown in Figure 3 of a side of handle (5), (6), stir (11) and (13) each 90 ° of shipping and reselling on another market in handle (5), (6) again, the bead (14) in the handle shown in Figure 5 (6) is entered under the effect of spring (15) in the concave point of ship and resell on another market (11); Equally, the bead (14) in the handle (5) also can enter in the concave point of ship and resell on another market (13), and handle (5) and (6) are pinned mutually, and two blocks of principal reflection plates are fixed as 180 °.Afterwards, catch the elastic hook of the two preceding turnover panels (10) of four hooks of the outside of principal reflection plate shown in Fig. 1 side view-promptly and two end blocking (2) one ends, make the back pumping board (3) and the end blocking (2) that coincide together, from after decide to extract out in the plate (1), same before pumping board (9) and preceding turnover panel (10) also can be from extraction in the predetermination plate (4); They are done rectilinear motion and to the utmost point prescribe a time limit, and as shown in figure 11, spring (21) acts on push rod (20), and push rod (20) withstands place kick (19) again, reaches self-locking.At last, the angle place that finger is pulled end blocking shown in Figure 9 (2) makes end blocking (2) be garden Zhou Yundong around rotating shaft shown in Figure 8 (17), elastic hook on the end blocking (2) can be snapped in the angle of back pumping board shown in Figure 10 (3) pin into 180 °; Preceding turnover panel (10) is principle expansion like this also.At this moment the utility model just all launches, and enters duty.

When it after hours, push elastic hook on the end blocking shown in Figure 10 (2) aside with finger, make end blocking (2) rotate back into the position that overlaps with back pumping board (3), stir shifting block shown in Figure 11 (8) again back pumping board (3) disengaging self-locking state just can be return in the Hou Dingban (1); The process that preceding turnover panel (10) and preceding pumping board (9) are return in the predetermination plate (4) is same as described above.At last, stir (11) and (13) each 90 ° of shipping and reselling on another market, handle (5), (6) are separated, two blocks of principal reflection plates go to around hinge (7) and overlap the position.

An internal thread that matches with the tripod attachment bolt is arranged on the handle (6) shown in Fig. 4 B-B section.

Fig. 6 is Fig. 2 C-C cut-open view, the inner structure that plate (1) and back pumping board (3) are decided in the reflection back." recessed " end that back pumping board (3) is placed in the Hou Dingban (1) is provided with two limited blocks, i.e. the A of O-O cut-open view point among Fig. 6 makes back pumping board (3) during rectilinear motion, not break away from and then decide plate (1) in two grooves in the plate (1) are decided in the back by them.The recessed end of back pumping board (3) can retreat to after decide plate (1) concavo-convex cooperation of protruding platform place, self-locking device shown in Figure 11 is housed below the cover plate (16).The thickness of the recessed end of back pumping board (3) equals the thickness sum that end blocking (2) and its are extracted part out, makes their insert the back and decides behind the plate (1) concordant with its upper surface.

Fig. 7 is the D-D cut-open view of Fig. 2, the inner structure of reflection predetermination plate (4) and preceding pumping board (9).Before the nose that is placed in the predetermination plate (4) of pumping board (9) be provided with two limited blocks, i.e. the A of Q-Q cut-open view point among Fig. 7, and limits in preceding two grooves of pumping board (9) in predetermination plate (4) by them and to do rectilinear motion, and do not break away from predetermination plate (4).The recessed platform place convex-concave that preceding pumping board (9) nose also can fall back on predetermination plate (4) cooperates, and cover plate also has self-locking device shown in Figure 11 below (16).The thickness of preceding pumping board (9) nose equals preceding turnover panel (10) and it self extracts the thickness sum of part out, makes their insertion predetermination plate (4) backs concordant with its upper surface.

Fig. 6, when Fig. 7 two covering devices are assembled together, at preceding pumping board (9), back pumping board (3) when being drawn to the limit, the nose of preceding pumping board (9) is close to the protruding platform of Hou Dingban (1); The recessed end of back pumping board (3) is close to the recessed platform of predetermination plate (4), is pinned by the cover of two under the cover plate (16) self-locking device respectively simultaneously, makes they and principal reflection plate mask that same normal direction be arranged, and guarantees the reflex unanimity.

In pumping board self-locking device shown in Figure 11, when back pumping board (3) from after when deciding to be evacuated to extreme position the plate (1), back pumping board (3) is with " recessed " shape platform location of predetermination plate (4), place kick (19) is under the effect of spring (21), be pressed into by push rod (20) in the garden column type concave point of back pumping board (3), the elastomer block (18) of concave point bottom is compressed, and the centre of sphere that is guaranteed place kick (19) by the relative depth of concave point is in the plane on back pumping board (3) surface, then back pumping board this moment (3) is crossed the centre of sphere to the acting force of place kick (19), makes back pumping board (3) self-locking.When desire is regained back pumping board (3), stir shifting block (8) and make push rod (20) compression spring (21), place kick (19) centre of sphere under the elastic force effect of elastomer block (18) exceeds the upper surface of back pumping board (3), back pumping board (3) to its acting force not after the centre of sphere; Back pumping board (3) is to the acting force of place kick (19), enter place kick (19) in the predetermined cavity of predetermination plate (4) by push rod (20) compression spring (21), then back pumping board (3) can withdraw from self-locking state together with end blocking (2), and returns in the Hou Dingban (1).Before pumping board (9) self-locking and withdraw from the principle of self-locking state, identical with above-mentioned principle.
