Description

Blind plate with drainage system for test box

Technical Field

The utility model relates to a high low temperature test case technical field, concretely relates to blind plate that has drainage system that proof box was used.

Background

The three-comprehensive test chamber is a test chamber integrating three functions of temperature, humidity and vibration. The device has the functions of rapid temperature change rate and providing comprehensive test environment of temperature, humidity, vibration and the like. The device is suitable for testing various performance indexes of aerospace products, information electronic instruments, materials, electricians, electronic products and various electronic elements in comprehensive severe environments. The three-combination test box consists of the following parts: the device comprises a test box body, a motion connection system, a control system, a refrigeration/dehumidification system, a heating/humidification system, an air duct system and the like.

However, when the three-comprehensive test chamber used in the market is used for testing in the chamber, the turntable at the front part sometimes needs to be installed, and sometimes does not need to be installed. When the rotary table is not needed, the upper blind plate is replaced to become a conventional high-low temperature humidity test box. Because the box body is internally provided with humidity, condensed water can be formed in the box body to accumulate when the high temperature and the low temperature are converted. The conventional method is to use a flat blind plate, accumulate condensed water, and clean the blind plate once after completing the test each time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a blind plate with drainage system that proof box was used to prior art's defect and not enough.

The utility model discloses a blind plate with a drainage system for a test box, which comprises a bottom cover plate and a convex plate, wherein the convex plate is arranged in the middle of the surface of the bottom cover plate to form a flange cover main body; and drainage grooves are formed around the joint of the convex plate and the bottom cover plate.

Further, at least one drain hole is arranged in the drain groove. The shape of the drain holes in this design is preferably circular.

Further, the drain hole is connected with an external drain pipe.

Furthermore, the bottom cover plate and the convex plate are both rectangular.

Furthermore, the water drainage tank is a 'return' type tank.

After the structure is adopted, the utility model discloses beneficial effect does: a blind plate that has drainage system that proof box was used, it adopts the blind plate of taking the drainage groove, neither influences the heat preservation function of blind plate, can do benefit to getting rid of the comdenstion water moreover, reduces the cost of labor of clearance, increases proof box frequency of use.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 6, the blind plate with a drainage system for a test chamber according to the present embodiment includes a bottom cover plate 12 and a convex plate 11, wherein the convex plate 11 is disposed in the middle of the surface of the bottom cover plate 12 to form a flange cover body 1;

and drainage grooves 2 are formed around the joint of the convex plate 11 and the bottom cover plate 12.

Further, at least one drain hole 3 is provided in the drain tank 2. The shape of the drain holes in this design is preferably circular.

Further, the drain hole is connected with an external drain pipe 4. In the design, the connection structure of the drain pipe and the drain hole can be easily realized by technicians in the industry, and belongs to the prior art, so the detailed description is omitted in the design. The external drain pipe can adopt a hose or a hard material pipe body as required, and common hardware such as a clamping belt and a tightening ring for fixing the drain pipe are added.

Furthermore, the bottom cover plate and the convex plate are both rectangular.

Furthermore, the drainage groove is a 'return' shaped groove.

The utility model discloses a theory of operation as follows:

the flange cover comprises a bottom cover plate and a convex plate, wherein the convex plate is arranged in the middle of the surface of the bottom cover plate to form a flange cover main body; and drainage grooves are formed in the periphery of the joint of the convex plate and the bottom cover plate. The drainage groove is provided with at least one drainage hole, the shape of the drainage hole is preferably circular, and the drainage hole is connected with an external drainage pipe.

When this design uses, when three combined test casees are experimental, when high low temperature conversion, can form the comdenstion water in the box and pile up, during accumulational comdenstion water can flow into water drainage tank this moment, rethread wash port to external drain pipe discharge to can not form the comdenstion water on the blind plate and pile up.

The blind plate in the design is called a flange cover, a blind flange or a pipe plug. It is a flange without holes in the middle and is used for plugging the pipeline opening. The problems of the traditional flange cover in the background art in practical use are solved: when the temperature is changed, condensed water accumulation is formed in the box body. Therefore, the design is reformed and improved on the basis of the traditional blind plate, and the blind plate has the advantages of low improvement cost and contribution to cost control. Therefore, the core of the design is to add a circle of drainage grooves at the bottom of the blind plate and connect the drainage grooves with an external drainage pipe 4.

The blind plate with the drainage groove has the advantages that: the blind plate with the drainage groove in the structure does not affect the heat preservation function of the blind plate, can be beneficial to removal of condensed water, reduces the labor cost of cleaning, and increases the use frequency of the test box.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
