Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is profile of the present invention;
Fig. 2 is the connection diagram of load fixture and lower chord.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See Fig. 1 and Fig. 2, the adjustable truss 100 of load provided by the invention, it is arranged on the downside of greenhouse roof, and is connected with the insulated column in greenhouse, and it comprises upper chord 110 and lower chord 120.
Lower chord 120 is opening section section bar 121, the opening section place needed user connects a load fixture 200, and load fixture 200 can carry out left and right displacement on opening section 121, during such suspender member, just do not need to disassemble, only need carry out left and right displacement by load fixture 200 on opening section 121.
Load fixture 200, it is CO type wire tensioner, and it comprises joint pin 210, upper hanging piece 220 and lower hanging piece 230 in hollow shape.
The interior surface of joint pin 210 is provided with connecting thread, and it is for installing hanging piece 220 and lower hanging piece 230, and upper hanging piece 220 and lower hanging piece 230 all can carry out displacement in joint pin 210.
Upper hanging piece 220, on it, end section is circular, it coordinates with any one connecting hole 121 on lower chord 120 and is fixedly connected with, its lower end is threaded column 221, threaded column 221 is connected with the connecting thread in joint pin 210, like this because upper hanging piece 220 upper end is fixed in connecting hole 121, joint pin 210 just can carry out upper and lower displacement along the threaded column 221 on upper hanging piece 220.
Lower hanging piece 230, it is for hanging items, and its upper end is threaded column 231, threaded column 231 is connected with the threaded engagement in joint pin 210, descend hanging piece 230 just can carry out upper and lower displacement in threaded column 221 by threaded column 231 like this, its lower end is suspension hook 232, and article can hang on suspension hook 232.
By above-mentioned enforcement, load fixture 200 can carry out left and right displacement by opening section cooperation on lower chord 120, and, joint pin 210 and lower hanging piece 230 all can carry out upper and lower displacement, so just do not dismantle load fixture 200 with regard to suspended article, need article only load fixture 200 need be moved down.
Because load fixture 200 adopts upper hanging piece 220 and joint pin 210 and joint pin 210 times hanging pieces 230 threaded engagement each other, the hanging intensity of load fixture 200 can not be affected so again.
Between lower chord 120 and upper chord 110, even distance is provided with the support unit 300 that several are isosceles trapezoid shape.
Support unit 300 is the bulk strengths for improving truss 100, and it is made up of two symmetrical support bars 310.
Support bar 310 is specially Z-shaped shape, and it is made up of upper horizon bar 311, lower horizon bar 312 and brace 313, upper horizon bar 311 and upper chord 210 flat contact, lower horizon bar 312 and lower chord 120 flat contact.
Brace 313 is supported between upper chord 110 and lower chord 120, and brace 313 is all 45 ° with the angle of upper chord 110 and lower chord 120, those skilled in the art are learnt by a large amount of experiments, by support bar 310 two ends and upper chord 110 and lower chord 120 flat contact, brace 313 and the angle of upper chord 110 and lower chord 120 are all set to 45 °, like this can the intensity of maximum raising truss 100.
In addition, two support bars 310 of each support unit 300 do not contact, distance between upper horizon bar 311 on two support bar 310 is 2 ~ 6cm, and often adjacent two support units 300 also do not contact each other, and the distance between often bottom adjacent two support units 300 is also 2 ~ 6cm.
Equally, by above-mentioned adjacent between support unit 300 be set to not contact, and distance is 2 ~ 6cm, and the support bar of two in support unit 300 310 is also set to not contact, and distance is also 2 ~ 6cm, this is also that those skilled in the art are learnt by a large amount of experiments, like this can the intensity of further maximized raising truss 100.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
