Abstract
The utility model discloses a composite environment testing system which comprises a vibration table and an environment case, a vertical bench of the vibration table is embedded in a groove at the bottom of the environment case, a sealing device is provide between the vertical bench of the vibration table and the groove; the sealing device comprises a framework structure, the inner side of the framework structure is connected to the vertical bench through an insulation material in a sealing mode, and the inner side surface at the bottom of the environment case is connected to the vertical bench through a flexible connection part. The composite environment testing system has good sealing and insulation effects, when the vibration testing table vibrates, the vibration of the upper environment case can be avoided by the flexible connection part, so that the environment case can be better protected, and the smooth performance of the composite environment tests can be ensured.
Description
Technical field
The utility model relates to a kind of environmental test system, particularly a kind of combined environment testing system.
Background technology
Environmental test is in order to guarantee product at the life period of regulation, under all environment of use, transportation or storage of expection, keeps functional reliability and the activity carried out.Be product to be exposed to estimate the performance of product under the environmental baseline of reality use, transportation and storage under nature or the artificial environmental baseline, and the influence degree of research environment factor and the mechanism of action thereof.
Combined environment testing is the important means of checking product quality and reliability, and for single environmental test, it is the actual working environment of analog equipment more truly, so test effect is better, and test efficiency is higher.
Shaking table is positioned at the bottom of environmental cabinet, and vibration environment is provided at the trial; The environmental cabinet on top provides the temperature and humidity environment at the trial.When combined environment testing, shaking table and environmental cabinet are all in running order, and the interface between environmental cabinet and the shaking table needs an appropriate sealing means.
Existing packoff generally directly is installed between shaking table vertical stand table top and the combined environment testing case by screw by a rubber parts, and following deficiency is arranged:
1, when hot test, cause the diffusing consumption of heat easily, heat insulation effect is not good;
2, after use a period of time, under high temperature and double vibrations condition, cause the rubber parts fatigure failure easily, when in the combined environment testing case, being in high humidity, cause the leakage of condensate water easily;
3, the rubber parts effect of heat insulation is not good, and when the hot test of combined environment testing case, its temperature inside the box can pass to the shaking table of bottom by rubber parts, causes the jigging platform moving coil temperature too high, can cause the scaling loss of moving-coil electric component when serious;
4, when shaking table vibrates, cause the vibration of environmental cabinet easily, damage environmental cabinet.
The environmental system packoff will reach following two purposes:
1) needs to connect shaking table and environmental cabinet well, when the shaking table of bottom vibrates, can not interfere with the operate as normal of the environmental cabinet on top, can not cause the damage of environmental cabinet;
When 2) in environmental cabinet, providing the temperature humidity environment, packoff can be realized insulation well, reduce the influence of external environment environmental cabinet closed test environment as far as possible, simultaneously when environmental cabinet is in high wet condition, condensate water in the environmental cabinet is leaked on the shaking table of bottom, causes short circuit or the damage of shaking table.
Summary of the invention
Technical problem to be solved in the utility model is, at the prior art deficiency, provides a kind of combined environment testing system; play sealing and heat insulation effect well, when vibration table vibrates, avoid the vibration of top environmental cabinet; the protection environmental cabinet is guaranteed carrying out smoothly of combined environment testing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of combined environment testing system, involving vibrations platform, environmental cabinet, the vertical stand of described shaking table embeds in the groove of described environmental cabinet bottom, is provided with packoff between the vertical stand of described shaking table and the described groove; Described packoff comprises framed structure, and described framed structure inboard is tightly connected by insulation material and described vertical stand, is connected by flexible attachment components between described environmental cabinet bottom inside surface and the described vertical stand.
It is the epoxy resin thermal insulation board of 8 ~ 20mm that thickness is fixedly arranged on the vertical stand table top of shaking table.
As preferred version, described insulation material is sponge.
Described flexible attachment components external edge is along being pressed on the described environmental cabinet bottom inside surface by press strip one, and described flexible attachment components internal edges is along being pressed on the described vertical stand table top by press strip two.
Compared with prior art; the beneficial effect that the utility model has is: the utility model can play sealing and heat insulation effect well; and during the vibration table vibration; flexible attachment components can be avoided the vibration of top environmental cabinet; protect environmental cabinet well, guaranteed carrying out smoothly of combined environment testing.
Description of drawings
Fig. 1 is the utility model one embodiment cut-open view;
Fig. 2 is the enlarged drawing of A part among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the utility model one embodiment involving vibrations platform 2 and environmental cabinet 1, the vertical stand 11 of described shaking table 2 embeds in the groove of described environmental cabinet 1 bottom, is provided with packoff between the vertical stand 11 of described shaking table 2 and the described groove; Described packoff comprises framed structure 4, and described framed structure 4 inboards are tightly connected by insulation material 5 and described vertical stand 11, is connected by flexible attachment components 4 between described environmental cabinet 1 bottom inside surface and the described vertical stand 11.
Described insulation material 5 is sponge.
It is the epoxy resin thermal insulation board of 8 ~ 20mm that thickness is fixedly arranged on the vertical stand table top.
Described flexible attachment components 4 external edge are along being pressed on the described environmental cabinet bottom inside surface by press strip 1, and described flexible attachment components 4 internal edges are along being pressed on the described vertical stand table top by press strip 2 10.
Press strip one and press strip two are separately fixed on environmental cabinet bottom inside and the shaking table vertical stand by trip bolt 9,8.
During installation, shaking table is adjusted to suitable position, adjust to the vibration vertical stand just in the same plane with the bottom surface of environmental cabinet.Then insulating sponge is bonded to the inside surface of framed structure, framed structure with bonding sponge heat-insulating material is installed on the environmental cabinet bottom surface then, the external edge edge of flexible attachment components is pressed on the environmental cabinet bottom surface by press strip one, fastening with trip bolt, be pressed on the shaking table vertical stand by the internal edges edge of press strip two with flexible attachment components again, fastening by screw, at last framed structure and environmental cabinet are got final product by screw is fastening.
Flexible attachment components one end JA(junction ambient) case bottom surface, an end connect shaking table vertical stand table top, play the effect that prevents that shaking table and environmental cabinet from interfering mutually.
The effect of insulation is played in the bonding framed structure of insulating sponge inboard.
