Description

Look around the movie screen framework

The utility model relates to a kind of movie screen framework of looking around, and it is adapted to multiple places such as gymnasium, assembly hall, court, large-scale cinema.

In background technology, look around the projection of film, be to carry out on the wall around by special projection hall the screen of showing a film being fixed on, cause it to exist the projection place to be restricted, the mobile film projection inconvenience, and the utilization factor of its film, is developed looking around the movie screen framework for overcoming these defectives because of the high defectives such as restriction that are subjected to a certain degree of its projection place investment.

The purpose of this utility model provides and a kind ofly shows that the place scope is wide, mobile film projection is convenient, the film utilization factor is high looks around the movie screen framework.

The purpose of this utility model is achieved in that

It comprises odd number by top one joint band rib first and lay trapezoid platform with a right ang first, the bottom one joint band rib first of motion picture projection machine bench and trapezoid platform with a right ang second, top and the bottom of foot rest between the trapezoid platform with a right ang third of 0-4 joint band rib first, by the bolt first bracing frame that assembling constitutes that combines as a whole

Be connected in the screw of adjacent supports frame upper end, several bracing frames are connected into the odd number that its medial surface is used for the screen of hanging ring radio movies the support that the screen hanger bracket inserts band rib second, rib third are locked with bolt second by the 6-12 joint, the crossing frame that adjacent stent is combined as a whole and constitutes by bolt third

Lean on its end shape groove with rib third embedding of bottom intersection in the adjacent stent, the supporting base of adjacent stent picking-up,

Be connected in the bolt fourth on the outboard end face intersection of adjacent stent, adjacent stent is tiltedly drawn fixing brace.

Fig. 9 is the annexation figure of Fig. 1 transom frame 2 and supporting base 3.

Below in conjunction with accompanying drawing, the utility model is done to describe further:

At first determine the position of 9 bracing frames 1 according to the place situation, on appointed positions, will by made such as angle steel, top one joint band rib first 12 and lay the trapezoid platform with a right ang the third 5 of 0-4 joint band rib first 12 between trapezoid platform with a right ang second 23, top and the bottom of trapezoid platform with a right ang first 22, bottom one joint band rib first 12 and foot rest 6 of motion picture projection machine bench 10, constitute bracing frame 1 by bolt first 11 assembling that combines as a whole.Again 9 support 7 usefulness bolt second 17 by crossing frame 2 outermost end of made such as shaped steel, aluminium alloy, plastic tube are connected in the adjacent supports frame 1 in the screw 16 of upper end, then with 9 by the third 9 connections of the joint of the 4-10 in the middle of the crossing frame 2 of made such as shaped steel, aluminium alloy, plastic tube support 7 usefulness bolts, and the rib of bottom intersection in the adjacent stent 7 the third 20 embedded in the shape groove 15 of supporting base 3, regulate its height by its degree of depth of inserting sleeve 14 of clamping screw first 13 controls; Also outside end face 19 intersections of adjacent stent 7 are tiltedly drawn and be fixed on the brace 4 with bolt fourth 18.The locking in the support 7 of at last screen hanger bracket 21 being packed into, hang on the bottom medial surface of screen hanger bracket 21 and support 7 looking around movie screen, 9 projectors place on the platen 10 of bracing frame 1, just can be in the gymnasium, multiple place projections such as assembly hall, court, large-scale cinema look around film.

When needs are changed place mobile film projection, take off 9 projectors and screen earlier, unclamp lock-screw second 24, remove screen hanger bracket 21, unload bolt the third 9, bolt fourth 18, extract the rib the third 20 that embeds adjacent stent 7 bottom intersections in the supporting base 3 end shape grooves 15, thereby unload brace 4, middle the 4-10 in supporting base 3, the crossing frame 2 saves support 7.Unload bolt second 17 again, thereby unload two end supports 7 in the crossing frame second.Unload bolt first 11 then, thereby unload trapezoid platform with a right ang first 22, trapezoid platform with a right ang second 23, right-angled trapezium the third 5.At last, all parts of breaking are packed into transport in the tote box, when reaching required projection place, by above-mentioned assembling process it is assembled again.

The utility model is compared the good effect that produces with background technology:

1. projection place scope is wide, thereby has improved the utilization rate in the multiple places such as gymnasium.

2. mobile film projection is convenient.

3. film utilization rate height.
