Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a test cabinet, the intelligent cabinet temperature adjusting device comprises a cabinet body 1, louvre 2 has been seted up to the both sides of the cabinet body 1, spout 3 has been seted up on the right side of the cabinet body 1, the right side of the cabinet body 1 is provided with hydraulic telescoping rod 4, hydraulic telescoping rod 4's top is provided with dull and stereotyped 5, dull and stereotyped 5's left side is provided with slider 6, slider 6 sets up in the inner chamber of spout 3, the inner chamber frictional force of spout 3 is less, dull and stereotyped 5's top is provided with step motor 7, step motor 7's the back is provided with connecting seat 8, be provided with lead screw 9 between step motor 7 and the connecting seat 8, the outer lane cover of lead screw 9 is equipped with movable block 10, be provided with connecting rod 24 between step motor 7 and the connecting seat 8, movable block 10 suit is at the outer lane of connecting rod 24, the top of movable block 10 is provided with servo motor 11, servo motor 11's left side is provided with pivot 12, pivot 12's left side louvre's left side cover is equipped with fan 13, fan 13 is seen through right side louvre 2 and gets into the cabinet body 1, blow off 2 the heat from the left side with the heat.

Wherein, be provided with the coupling joint between step motor 7's output shaft and the lead screw 9, step motor 7 rotates the rotation that drives lead screw 9, is provided with the coupling joint between servo motor 11's left side and pivot 12, and servo motor 11 rotates and drives pivot 12 and rotate.

In this embodiment, the stepping motor 7 is also started, and the stepping motor 7 drives the screw rod 9 to complete rotation because a coupler is arranged between the stepping motor 7 and the screw rod 9; the servo motor 11 is started, and due to the existence of the coupler, the servo motor 11 drives the rotating shaft 12 and the fan 13 to rotate, wind power is blown in from the heat dissipation hole 2 on the right side, and heat of the cabinet body 1 is blown out from the heat dissipation hole 2 on the left side.

Wherein, the inner cavity teeth of the moving block 10 are meshed with the outer ring teeth of the lead screw 9, and the lead screw 9 can drive the moving block 10 to move when rotating.

In this embodiment, because the outer ring teeth of the lead screw 9 are meshed with the inner ring teeth of the moving block 10, and because of the existence of the connecting rod 24, the moving block 10 cannot rotate along with the rotation of the lead screw 9, so that the rotation of the lead screw 9 can drive the moving block 10 to move in the front-back direction, and then the servo motor 11 and the fan 13 at the top can move in the front-back direction, thereby enlarging the heat dissipation area.

Wherein, the top of the cabinet body 1 is provided with a glass groove 14, an inner cavity of the glass groove 14 is provided with toughened glass 15, the back of the cabinet body 1 is provided with a cover plate 16, and the cover plate 16 is connected with the cabinet body 1 through a hinge.

In this embodiment, need look the inside experimental condition of the cabinet body 1 as the staff, need open apron 16 round the hinge this moment, see through toughened glass 15 and observe, avoid directly opening the potential safety hazard that qianmen 17 probably exists, convenient and fast.

Wherein, the front of the cabinet body 1 is provided with a front door 17, and a hinge connection is arranged between the front door 17 and the cabinet body 1.

In this embodiment, the front door 17 is opened in cooperation with the hinge when it is necessary to use the working components inside the cabinet 1, and the front door 17 is closed in normal operation.

Wherein, the bottom of the cabinet body 1 inner chamber is provided with dehumidification frame 18, and through-hole 19 has been seted up on dehumidification frame 18's the front, is provided with sponge 20 in through-hole 19's the inner chamber, and through-hole 19 and sponge 20 are multiunit matrix array.

In this embodiment, the bottom of the inner cavity of the cabinet body 1 is provided with a dehumidifying rack 18, a sponge 20 is arranged in the through hole 19, the sponge 20 can absorb moisture, and the through holes 19 and the sponge 20 of the multiple groups of matrix arrays can improve the dehumidifying effect inside the cabinet body 1.

Wherein, the left side at dehumidification frame 18 top is provided with supporting seat 21, and the right side of supporting seat 21 sets up fixing base 22, and the top of supporting seat 21 is provided with thermometer 23, and thermometer 23 can show the inside temperature of cabinet 1.

In this embodiment, the related electrical device can be placed on the supporting base 21 and the fixing base 22. The staff can also observe the indication number of the thermometer 23 through the toughened glass 15, and know the temperature of the cabinet body 1 at the moment, so as to determine whether to use the fan 13 for heat dissipation.

The working principle is as follows: when the working components in the cabinet 1 need to be used, the front door 17 is opened by the hinge, the relevant electrical equipment can be placed on the supporting seat 21 and the fixed seat 22, and the front door 17 is closed during normal operation. At experimental in-process, because electrical equipment's work can produce a large amount of heats, servo motor 11 can start this moment, because the existence of shaft coupling, servo motor 11 can drive the rotation of pivot 12 and fan 13, blows in wind-force from the louvre 2 on right side, blows out the heat of the cabinet body 1 from the louvre 2 on left side. When the fan 13 normally works, the stepping motor 7 is also started at the moment, and the stepping motor 7 drives the screw rod 9 to complete rotation due to the fact that the coupler is arranged between the stepping motor 7 and the screw rod 9. Because the outer ring teeth of the lead screw 9 are meshed with the inner ring teeth of the moving block 10, and because of the existence of the connecting rod 24, the moving block 10 cannot rotate along with the rotation of the lead screw 9, the rotation of the lead screw 9 can drive the moving block 10 to move in the front-back direction, and then the servo motor 11 and the fan 13 at the top can move in the front-back direction, so that the heat dissipation area is enlarged. After the heat dissipation at the same height is completed, the hydraulic telescopic rod 4 drives the flat plate 5 to move up and down through telescopic operation. The up-and-down movement of the flat plate 5 can drive the up-and-down movement of the stepping motor 7 and the moving block 10, and further drive the up-and-down movement of the servo motor 11 and the fan 13, so that the areas with different heights of the cabinet body 1 can realize the heat dissipation effect, and the efficiency of heat outward discharge is improved. The left side of the flat plate 5 is provided with a slide block 6, and the slide block 6 can move in the inner cavity of the sliding chute 3, so that the up-and-down moving direction of the flat plate 5 can be limited, and the flat plate 5 can move more stably. When the staff need watch the test condition of cabinet 1 inside, need open apron 16 round the hinge this moment, see through toughened glass 15 and observe, avoid directly opening the potential safety hazard that qianmen 17 probably exists, convenient and fast. The indication number of the thermometer 23 can be observed through the toughened glass 15, so that the temperature of the cabinet body 1 at the moment can be known, and whether the fan 13 is used for heat dissipation or not is determined. When not needing to observe, cover 16 round the top of hinge lid at toughened glass 15 to the realization is to the sheltering from of toughened glass 15, avoids outside sunshine to penetrate cabinet body 1 inside directly. The bottom of the inner cavity of the cabinet body 1 is provided with a dehumidifying rack 18, a sponge 20 is arranged in the through hole 19, the sponge 20 can absorb moisture, and the through holes 19 and the sponge 20 of the multiple groups of matrix arrays can improve the dehumidifying effect inside the cabinet body 1.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
