Nodal analysis method, bolt sphere is connected with rod member by universal joint, and is fixed the angle of universal joint by bolt card；Described
Bolt sphere uses high hard transparent resin material saturating, high.
Nonadjustable for angle in actual configuration rod member, based on actual bolted spherical node structure, is led to by this utility model
Cross universal joint to be connected with bolt sphere, realize rod member adjustable angle in a model, carry out rod member angle by bolt card simultaneously
Adjust later fixing, the not only convenient demonstration of this structure, also facilitate student resource to explore.On the other hand, use height saturating, high hard
The bolt sphere made of transparent resin can see internal structure situation intuitively, facilitate observation of students, study.
Further, for preferably realizing this utility model, described universal joint includes using gimbal structure to connect
Fixing seat and sleeve, fixing seat is connected with bolt sphere, and sleeve is connected with rod member, the bolt card being arranged in bolt sphere and sleeve
Outer surface contact with the angle of fixing sleeve.
Further, for preferably realizing this utility model, described bolt card is bolt, and the head of bolt is with bolt sphere even
Connect and screw tip is conflicted at the outer surface of sleeve.Described bolt card uses nominal diameter to be 20mm, pitch is 3mm, a length of
The bolt of 100mm.
Further, for preferably realizing this utility model, described all around stems is distributed multiple bolt card uniformly.
Further, for preferably realizing this utility model, the interior raceway of described sleeve by the cage of built-in steel ball with
The outer raceway of fixing seat connects.
Further, for preferably realizing this utility model, described sleeve uses screwed connection with rod member.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) in this utility model, bolt sphere uses high hard transparent resin material saturating, high, can see ball node intuitively
Internal structure；
(2) in this utility model, bolt sphere is connected by universal joint with rod member, the adjustable angle that rod member is installed, both side
Just carry out the demonstration of multiple connection scheme, facilitate again student to do it yourself to carry out new exploration.
(3) this utility model simple in construction, can be effectively improved quality of instruction.

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not
It is limited to this.
Embodiment 1:
A kind of solid proportional bolt sphere 1 nodal analysis method for Elements of Space Grid Truss example of the present embodiment, as it is shown in figure 1, mainly
To be achieved through the following technical solutions: a kind of solid proportional bolt sphere 1 nodal analysis method for Elements of Space Grid Truss example, use high thoroughly,
The bolt sphere 1 that high hard transparent resin material is made is connected with rod member 3 by universal joint 2, and by being arranged in bolt sphere 1
Bolt card 4 fix the angle of its sleeve 22 of universal joint 2.The fixing seat 21 of described universal joint 2 is arranged on bolt sphere 1
In, the sleeve 22 using gimbal structure to be connected with the fixing seat 21 of universal joint 2 stretches out bolt sphere 1 and uses with rod member 3
Screwed connection.One end of described bolt card 4 is by being threadably mounted in bolt sphere 1, and the other end is conflicted at the outer surface of sleeve 22
