The utility model is related to testing equipment technical field, more particularly to a kind of large-scale environmental test chamber bearing structure, including inner bag and peripheral steelframe, each stress point on the inner bag and flexible fixed point attachment structure is provided between the tie point of the peripheral frame, test hole site sets flexible through attachment structure, flexibility fixed point attachment structure includes fixed block, threaded rod and flexible connecting member, fixed block is arranged on the inner side of the inner bag, one end of threaded rod is connected through the inner bag and with the fixed block, flexible connecting member is enclosed within the threaded rod, the other end of threaded rod is connected with the peripheral steelframe；Flexibility includes the left and right sleeve being arranged in instrument connection and the bellows being connected with the left and right sleeve staking through attachment structure.Present apparatus force analysis point at the beginning of mechanism designs, in the enterprising row buffering design of the tie point of each stress point and external frame, is buffered due to harm of the pressure change to inner bag in cabin with flexible connected mode.
Description
Technical field
The utility model is related to testing equipment technical field, more particularly to a kind of large-scale environmental test chamber bearing structure.
Background technology
In environmental simulation experiment, pressure is a very important influence factor, and particularly equipment damage aspect is seemed
Become apparent, the structure design of equipment does not typically possess extensibility, belong to fixed empty formula structure, once internal generation is swollen
It is swollen, it is either regular that irreversible infringement will be caused to structure again without rule.Particularly in large-scale environment
The structure design aspect of experimental cabin is particularly important.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of large-scale environmental test chamber pressure-bearing knot
Structure, reduces due to the destructive lesion when change of temperature causes inner bag internal pressure to increase or reduce to inner bag in itself.
The utility model to achieve the above object, using following technical scheme：
A kind of large-scale environmental test chamber bearing structure, it is characterised in that:Including inner bag and peripheral steelframe, on the inner bag
Each stress point and the tie point of the peripheral frame between be provided with flexible fixed point attachment structure, test hole site sets flexible
Through attachment structure, the flexible fixed point attachment structure includes fixed block, threaded rod and flexible connecting member, and the fixed block sets
Put in the inner side of the inner bag, one end of the threaded rod is connected through the inner bag and with the fixed block, the flexibility is even
Fitting is enclosed within the threaded rod, and the other end of the threaded rod is connected 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 being connected with the left and right sleeve staking.
Preferably, the flexible connecting member is spring.
Preferably, it is provided with sealing strip between the flexible connecting member and the inner bag.
The beneficial effects of the utility model are:Relative to prior art, present apparatus force analysis point at the beginning of mechanism designs,
In the enterprising row buffering design of the tie point of each stress point and external frame, flexible fixed point connection is fabricated to, tests bore portion system
Flexibility is made through connection, is buffered due to harm of the pressure change to inner bag in cabin with flexible connected mode.
Brief description of the drawings
Fig. 1 is the structural representation of flexible fixed point connection in the utility model；
Fig. 2 is the flexible structural representation through connection in the utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.Such as Fig. 1 and Fig. 2 institutes
Show, a kind of large-scale environmental test chamber bearing structure, including inner bag 1 and peripheral steelframe 2, each stress point on the inner bag with
Flexible fixed point attachment structure is provided between the tie point of the peripheral frame, test hole site sets flexibility and runs through attachment structure,
The flexible fixed point attachment structure includes fixed block 3, threaded rod 4 and flexible connecting member 5, and the flexible connecting member is spring.
The fixed block is arranged on the inner side of the inner bag, and one end of the threaded rod connects through the inner bag and with the fixed block
Connect, the flexible connecting member is enclosed within the threaded rod, the other end of the threaded rod is connected with the peripheral steelframe, works as inner bag
When there is outwards deformation, by compressing compression spring, after inner liner pressure disappears, resetted by spring.During assembling, welding
After the complete inner bag module with fixed block, screw rod of screwing on puts flexible connecting member, places flexible sealing strip, with rivet of remaining silent
It is fixed, screw rod is screwed on and be welded at steelframe after nut.Further according to design specific requirement, certain heating tape need to be arranged.
It is described it is flexible through attachment 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, afterwards through reserved instrument connection,
Flexible sealing strip is placed in box inside, pulling rivet is fixed using remaining silent.
Present apparatus force analysis point at the beginning of mechanism designs, is delayed on tie point of each stress point with external frame
Punching is designed, and is fabricated to flexible fixed point connection, and test bore portion is fabricated to flexibility through connection, is buffered with flexible connected mode
Due to harm of the pressure change to inner bag in cabin.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
