Abstract
The utility model provides a constant temperature and humidity chamber with an air volume adjustment device. The constant temperature and humidity chamber comprises a constant temperature and humidity chamber body and an air volume adjustment box, wherein the air volume adjustment box is arranged in the constant temperature and humidity chamber body; the air volume adjustment box comprises an adjustment outer box body, an inner box body, adjustment devices and air adjustment holes; the outer box body and the inner box body are in cup joint in a manner of relatively moving; openings are formed in the same sides of the outer box body and the inner box body; the inner wall side of the outer box body and the outer wall side of the inner box body can be in complete fit; adjustment devices are arranged on sides (opposite to the openings) of the inner box body and the outer box body and used for realizing relative movement of the inner box body and the outer box body; the air adjustment holes are formed in the walls of the inner box body and the outer box body; the air volume adjustment device is additionally arranged in the constant temperature and humidity chamber, so that the air volume can be further adjusted; the uniformity and stability of the air volume and the air speed can be guaranteed; the limitation that the air volume of the original constant temperature and humidity chamber only reaches the set value of the fan can be broken through; the device is simple and compact in structure, convenient to manufacture and low in cost.
Description
Technical field
The utility model belongs to climatic chamber field, especially relates to a kind of climatic chamber that regulates inner air quantity structure that has.
Background technology
Constant temperature humidity chamber is for detection of the equipment of material performance under various environment and test heat-resisting, cold-resistant, resistance to dry, the moisture resistance properties of various materials.
Constant temperature humidity chamber is made up of temperature adjustment (heat, freeze) and humidification two parts.By being arranged on the rotary fan of casing inner top, air is entered to casing and realize temperature, the humidity in gas circulation, balance box, the data that gathered by the built-in temperature of casing, humidity sensor, reach temperature, humidity controller (miniature message handler) carries out editing and processing, assign conditioning instruction, by heating evaporation list in air-heating unit, condenser pipe and tank without jointly complete.Rotary fan in casing can make to produce in case the air quantity of certain flow rate, but in the time that needs complete experiment under micro-air quantity, more difficult, also cannot obtain more even, fine and smooth wind speed.
Summary of the invention
Problem to be solved in the utility model is to design the climatic chamber of air quantity in a kind of regulating box more equably for climatic chamber.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of climatic chamber with volume adjusting apparatus, comprises constant temperature and humidity casing and the air quantity regulating box body of the portion that sets within it.
Air quantity regulating box body comprises adjusting outer case, internal box, adjusting device and wind adjusting hole, relatively-movable socket and be the same side opening between outer case and internal box, outer case internal face and internal box outside wall surface can all be fitted, the side that internal box is relative with opening with outer case is provided with and makes its adjusting device relatively moving, and internal box and outer case can relatively move but be equipped with wind adjusting hole on unseparated wall.
In such scheme, internal box becomes matrix to arrange with the wind adjusting hole arranging in outer case.
In such scheme, adjusting device is screw structure, and leading screw one end is fixed in outer case through the adjusting screwed hole of internal box, and the other end extends to beyond internal box opening one side and connects and regulates handle.
In such scheme, internal box and outer case are cuboid, square or cylinder.
In such scheme, internal box opening one side is provided with transparent window, and form offers test specimen and picks and places mouth.
Advantage and the good effect that the utlity model has are: in climatic chamber, set up volume adjusting apparatus, can further regulate air quantity, ensure the even, stable of air quantity and wind speed, the air quantity that has solved original climatic chamber can only meet the limitation of fan setting value effect; Apparatus structure is simply compact, easy to make with low cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, 2, the utility model is a kind of climatic chamber with volume adjusting apparatus, comprise outer case 2, internal box 1, adjusting device and wind adjusting hole 6 and 7, relatively-movable socket and be the same side opening between outer case 2 and internal box 1, outer case 2 internal faces and internal box outside wall surface can all be fitted, the relative side of opening of internal box 1 and outer case 2 is provided with and makes its adjusting device relatively moving, and internal box and outer case can relatively move but be equipped with wind adjusting hole on unseparated wall.Internal box becomes matrix to arrange with the wind adjusting hole arranging in outer case.Adjusting device is screw structure, and leading screw 3 one end are fixed on internal box 1 through the adjusting screwed hole 5 of outer case 2, and the other end connects adjusting handle 4.Internal box opening one side is provided with transparent window, and form offers test specimen and picks and places mouth 8.
In internal box and outer case, be equipped with wind adjusting hole, adjusting screw, produces relative displacement between internal box and outer case, causes the wind adjusting hole of corresponding setting on inside and outside casing also to produce relative displacement.When adjusting screw is fitted inside and outside casing completely, all inside and outside wind adjusting holes that are oppositely arranged overlap completely, make to enter in casing maximum quantity of wind; Adjusting screw, makes inside and outside casing produce relative displacement, and the wind adjusting hole being oppositely arranged is gradually interleaved, and air vent diminishes gradually, and the air quantity entering in casing is diminished; In the time that adjusting screw staggers relative air vent completely, wind adjusting hole is completely covered, calm entering in casing.Casing can adopt the forms such as cuboid, square or column, all can obtain the uniform lab space of air quantity.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
