Abstract

The utility model discloses a stage frame, which mainly comprises two support frames and a plurality of support bars. The utility model is characterized in that the support frame which is provided with an appropriate morphological frame body structure is composed of a rod body, a connecting strip, etc. One end of each support bar is rigidly arranged in an assembling hole of the bar body of the support frame, and the other end is rigidly arranged in the assembling hole of the bar body of the other support frame. Thus, compared with a conventional technology, the support frame and the other support frame can have better support performance after integrally assembled, because a plurality of support bars are rigidly arranged between the support frame and the other support frame.

Description

The stage frame

Technical field

The utility model relates to a kind of stage frame, especially a kind of stage frame that has preferable supportive, can be used for large-scale stage.

Background technology

Known to previous, the stage shelf structure is main as notification number 379773 at present, application number 87218298, January 11 89 year day for announcing, patent name " stage structural improvement ", the main structural principle of this patent is to have the base carrier and the structural supporter of predetermined number, base carrier and structural supporter are and utilize the body of rod with the connection strap of predetermined number each bar to be connected and one links to each other, base carrier and structural supporter are also organized and are established several contiguous blocks, organize again in contiguous block and to establish brace, utilize brace that base carrier and structural supporter are interconnected and spiral shell solid, also can utilize brace to interconnect between structural supporter and the structural supporter and spiral shell solid, so can constitute a complete stage structure, the main structure of lifting wheel seat is also identical with structural supporter also to have contiguous block and a brace, difference and have wheel and mainly can utilize wheel to provide lifting to move line by line.

The main advantage of above-mentioned patent is to make the stage structure to utilize base carrier and structural supporter can finish the most basic framework of a stage, but this patent still has following shortcoming:

When base carrier and structural supporter or structural supporter and another structural supporter set firmly mutually, mainly utilize screw on the brace to align solid shown in Figure 7 as this case of back spiral shell mutually, this structure sets firmly mode in the bar institute part of downward strength by predetermined number, but then all need when imposing on mutually the place of setting firmly be supported by the solid bolt of screw spiral shell on the brace for lateral force, set firmly mutually when locating if there is a bigger lateral force to impose on, shearing between bolt bears promptly quite big, bear the i.e. major defect of patent stage structure for this reason of lateral force and depend merely on bolt, therefore generally speaking the stage structure of above-mentioned patent case only can be used in scale than woodwing.

In view of the above-mentioned stage frame of commonly using in structural scarce fraud, the inventor is research and development constantly also, have the product of a practicality to come out finally, strengthen the competitiveness on the product.

Summary of the invention

The purpose of this utility model provides a kind of stage frame, and it mainly comprises two bracing frames and forms with the number support bar, it is characterized in that:

Bracing frame is the frame structure by suitable forms that member constituted such as the body of rod and connection straps;

The number support bar is in an end is fixedly arranged on the assembly hole of the bracing frame body of rod, and the other end is fixedly arranged in the assembly hole of another bracing frame body of rod; By this, can be between bracing frame and another bracing frame because of inside is installed with several support bars, comparable located by prior art has more preferable supportive after the overall package.

The utility model provides a kind of stage shelf structure improvement, mainly comprising two bracing frames forms with the number support bar: bracing frame can be made of members such as combination block, the body of rod and connection straps, combination block becomes a demihull shape, has suitable thickness, be provided with several assembly holes and pilot hole in the combination block appropriate position, combination block integral body is one of the forming, the number assembly hole can be in conjunction with the number body of rod, utilize connection strap to strengthen braced structures between each body of rod between each body of rod again, combination block, the number body of rod and connection strap can constitute a complete bracing frame comprehensive architecture; Number support bar one end is fixedly arranged in the assembly hole of the bracing frame body of rod, and the other end is fixedly arranged in the assembly hole of another bracing frame body of rod, can be between bracing frame and another bracing frame because of inside is installed with several support bars, and comparable located by prior art has better supportive after the overall package.

In order further to understand the purpose of this utility model, feature and effect, now reach embodiment in conjunction with the accompanying drawings and do following explanation.

The specific embodiment

As shown in Figure 1, the utility model provides a kind of stage frame, and it mainly comprises two bracing frames and forms with number support bar 20;

Bracing frame can be made of members such as combination block 10, the body of rod 40 and

connection straps

50,10 one-tenth one demihull shapes of combination block, has suitable thickness, be provided with several assembly holes 11 and pilot hole 12 in combination block 10 appropriate positions, number assembly hole 11 can set firmly several bodies of

rod

40,40 of each bodies of rod utilize connection strap 50 to set firmly mutually again, and to strengthen the braced structures of integrated support frame, combination block 10, the number body of rod 40 and connection strap 50 can constitute a complete bracing frame framework;

Number support bar 20 at one end is fixedly arranged in the assembly hole 11 of the bracing frame body of rod 40, and the other end is fixedly arranged in the assembly hole 41 of another bracing frame body of rod 40, promptly as shown in Figure 2, is best enforcement state of the present utility model after overall package.

The utility model biggest advantage: case utilizes mainly when lateral force is born at the place of setting firmly mutually that the solid bolt of screw spiral shell supports on the brace before the above-mentioned patent, and the utility model structure aligns the solid bolt support of back spiral shell with the pilot hole 12 that another bracing frame makes up piece 10 mutually except that the pilot hole 12 that bracing frame makes up piece 10, at one end be fixedly arranged on because of support bar 20 in the assembly hole 11 of the bracing frame body of rod 40, the other end is fixedly arranged in the assembly hole 41 of another bracing frame body of rod 40, therefore lateral support structure of the present utility model is born jointly by support bar 20 and bolt, goes up structure of the present utility model relatively and promptly has better supportive in the place of setting firmly mutually than case before the above-mentioned patent.

As shown in Figure 3, another embodiment of the utility model support bar 20 forms a projection 21 in support bar 20 appropriate positions.

As shown in Figure 4, the utility model support bar 20 second embodiments form a quadrangle block in number support bar 20 appropriate positions, make several support bars 20 set firmly framework in aggregates mutually.

As Fig. 5, Figure 6 and Figure 7, number support bars 20 also can be fixedly arranged on several difform bracing frames, and bracing frame shown in Figure 6 is leg-of-mutton support frame structure, bracing frame shown in Figure 8 be application number 87218298 patent cases shown in Figure 3 commonly use bracing frame.

As shown in Figure 8, support bar 20 can be a hollow rod body, and so the register hole 22 of support bar 20 can be sheathed on outside the body of rod 40 of bracing frame, and this moment, bracing frame did not promptly have the structure of combination block 10.

In sum, the utility model has novelty and practical effect concurrently, and can improve the shortcoming of commonly using.
