Description
Technical field
The present invention relates to technical field of test equipment more particularly to a kind of large-scale environmental test chamber bearing structures.
Background technique
In environmental simulation experiment, pressure is a very important influence factor, is especially seemed to equipment damage aspect
It becoming apparent, the structure design of equipment does not generally have extensibility, belong to fixed empty formula structure, once internal generation is swollen
It is swollen, it is either regular that irreversible damage will be caused to structure again without rule.Especially in large-scale environment
The structure design aspect of experimental cabin is particularly important.
Summary of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and a kind of large-scale environmental test chamber bearing structure is provided,
Reduce due to when the variation of temperature causes liner internal pressure to increase or reduce to the destructive lesion of liner itself.
The present invention to achieve the above object, using following technical scheme:
A kind of large size environmental test chamber bearing structure, it is characterised in that: including liner and peripheral steelframe, on the liner
Each stress point and the peripheral frame tie point between be equipped with flexible fixed point connection structure, the setting of test hole site is flexible
Through connection structure, the flexible fixed point connection structure includes fixed block, threaded rod and flexible connecting member, and the fixed block is set
It sets in the inside of the liner, one end of the threaded rod passes through the liner and connect with the fixed block, and the flexibility is even
Fitting covers on the threaded rod, and the other end of the threaded rod is connect with the peripheral steelframe；It is described flexible through connection knot
Structure includes the left and right sleeve being arranged in instrument connection and the bellows that connect with the left and right sleeve staking.
Preferably, the flexible connecting member is spring.
Preferably, sealing strip is equipped between the flexible connecting member and the liner.
The beneficial effects of the present invention are: compared with the existing technology, present apparatus force analysis point at the beginning of mechanism designs, each
A stress point and the enterprising row buffering of the tie point of external frame design, and are fabricated to flexible fixed point connection, and test bore portion is fabricated to
Flexibility is buffered with connection type flexible through connection due to harm of the pressure change to liner in cabin.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of flexible fixed point connection in the present invention；
Fig. 2 is the flexible structural schematic diagram through connection in the present invention.
Specific embodiment
With reference to the accompanying drawing and the preferred embodiment specific embodiment that the present invention will be described in detail.As depicted in figs. 1 and 2,
A kind of large size environmental test chamber bearing structure, including liner 1 and peripheral steelframe 2, each stress point and institute on the liner
It states and is equipped with flexible fixed point connection structure between the tie point of peripheral frame, the setting of test hole site is flexible to run through connection structure, institute
Stating flexible fixed point connection structure includes fixed block 3, threaded rod 4 and flexible connecting member 5, and the flexible connecting member is spring.Institute
The inside that the liner is arranged in fixed block is stated, one end of the threaded rod passes through the liner and connect with the fixed block,
The flexible connecting member covers on the threaded rod, and the other end of the threaded rod is connect with the peripheral steelframe, when liner is sent out
When raw deformation outward, by compressing compressed spring, after inner liner pressure disappears, resetted by spring.When assembly, weld
After liner module with fixed block, screw rod is screwed on, flexible connecting member is put on, places flexible sealing strip, it is solid with silent rivet
It is fixed, it is welded at steelframe after screw rod is screwed on nut.Furthermore according to design specific requirement, certain heating tape need to be arranged.
It is described it is flexible through connection structure include the left and right sleeve 6,7 being arranged in instrument connection and with the left and right set
The bellows 8 of cylinder staking connection.Heating tape is first arranged according to design requirement before being attached, passes through reserved instrument connection later,
Flexible sealing strip is placed in box inside, is fixed using silent pulling rivet.
Present apparatus force analysis point at the beginning of mechanism designs, is delayed on each stress point and the tie point of external frame
Punching designs, and is fabricated to flexible fixed point connection, and test bore portion is fabricated to flexibility through connection, is buffered with connection type flexible
Due to harm of the pressure change to liner in cabin.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
