[0004] In the high and low temperature damp and heat test chamber, no special base structure is provided at the bottom of the high and low temperature damp and heat test chamber body. It is found in use that during low temperature tests, especially in an environment with high humidity, since the outer surface temperature of the high and low temperature damp and heat test chamber body is lower than the ambient temperature, small water droplets will condense on its surface, and these condensed small water droplets will directly drip onto the ground, causing pollution to the ground. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a high and low temperature alternating damp and heat test chamber, which is used in an environment with high humidity and can collect the water droplets condensed on the outer surface of the high and low temperature alternating damp and heat test chamber body to avoid directly dripping onto the ground and causing pollution.

[0006] To achieve the above purpose, the utility model provides a high and low temperature alternating damp and heat test chamber, which includes a high and low temperature alternating damp and heat test chamber body and a base for supporting the high and low temperature alternating damp and heat test chamber body; a limiting groove is provided on the upper surface of the base, a diversion inclined surface is provided at the top end of the limiting groove, and a diversion groove is provided on the side wall of the limiting groove; a rectangular hole extending in the left - right direction is provided in the middle of the bottom surface of the limiting groove, and a liquid collecting box is inserted and installed on the left or right side of the base; the liquid collecting groove of the liquid collecting box is communicated with the rectangular hole, and a plurality of supporting protrusions are provided on both sides of the bottom surface of the limiting groove located at the two sides of the rectangular hole.

[0007] Preferably, sliding grooves are provided on both sides of the rectangular hole; on both sides of the upper end of the liquid collection box, there are side wing plates that are slidably inserted into the sliding grooves.

[0008] Preferably, a hand-gripping groove is provided at the outer end of the liquid collection box, and a gripping plate is provided at the top of the hand-gripping groove.

[0009] Preferably, the support protrusions include support blocks provided at the four corner positions of the limit groove.

[0010] Preferably, the support protrusions further include a plurality of support cylinders provided on both sides of the rectangular hole.

[0011] Preferably, a support foot is provided at each of the four corner positions of the bottom surface of the base.

[0012] Preferably, the bottom surface of the limit groove is a slope surface, and the slope surface is arranged such that the height gradually decreases from the end far away from the rectangular hole to the end close to the rectangular hole.

[0013] According to the above technical solution, the present utility model provides a high and low temperature alternating damp heat test chamber, which includes a high and low temperature alternating damp heat test chamber body and a base for supporting the high and low temperature alternating damp heat test chamber body; a limit groove is provided on the upper surface of the base, a diversion slope is provided at the top of the limit groove, and a diversion groove is provided on the side wall of the limit groove; a rectangular hole extending in the left and right directions is provided in the middle of the bottom surface of the limit groove, and a liquid collection box is inserted on the left or right side of the base; the liquid collection groove of the liquid collection box is communicated with the rectangular hole, and a plurality of support protrusions are provided on both sides of the bottom surface of the limit groove where the rectangular hole is located.

[0014] When using this high and low temperature alternating damp heat test chamber, when the high and low temperature alternating damp heat test chamber body is at a low test temperature, its surface temperature will be lower than the ambient temperature. Especially in an environment with high humidity, small water droplets will condense on the outer surface of the high and low temperature alternating damp heat test chamber body. As the small water droplets continue to condense, they will flow downward along the outer wall of the high and low temperature alternating damp heat test chamber body. The flowing water droplets first enter the diversion slope, then flow along the diversion groove from the diversion slope to the rectangular hole, and finally enter the liquid collection box to be centrally collected. When assembling this high and low temperature alternating damp heat test chamber, the bottom of the high and low temperature alternating damp heat test chamber body is inserted into the limit groove, and the high and low temperature alternating damp heat test chamber body is stably supported by a plurality of support protrusions. Due to the action of the plurality of support protrusions, the bottom surface of the high and low temperature alternating damp heat test chamber body will not directly contact the liquid flowing on the bottom surface of the limit groove, forming a good isolation. When the liquid in the liquid collection box accumulates to a certain amount, it can be drawn out from the side and poured out.

Especially in an environment with high humidity, small water droplets will condense on the outer surface of the high and low temperature alternating humidity and heat test chamber body 1. As the small water droplets continue to condense, they will flow downward along the outer wall of the high and low temperature alternating humidity and heat test chamber body 1. The flowing water droplets first enter the diversion inclined surface 7, then flow along the diversion groove 12 from the diversion inclined surface 7 to the rectangular hole 11, and finally enter the liquid collecting box 4 to be centrally collected. When assembling this high and low temperature alternating humidity and heat test chamber, the bottom of the high and low temperature alternating humidity and heat test chamber body 1 is inserted into the limiting groove 15, and the high and low temperature alternating humidity and heat test chamber body 1 is stably supported by a plurality of support protrusions. Due to the action of the plurality of support protrusions, the bottom surface of the high and low temperature alternating humidity and heat test chamber body 1 will not directly contact the liquid flowing on the bottom surface of the limiting groove 15, forming a good isolation. When the liquid in the liquid collecting box 4 accumulates to a certain amount, it can be drawn out from the side and poured out. When the high and low temperature alternating humidity and heat test chamber body 1 operates at a low temperature, the water droplets condensed on the outer surface will be centrally collected in the liquid collecting box 4 for centralized treatment, avoiding water droplets dripping onto the ground and causing pollution.

Through the sliding cooperation between the wing plates 6 and the sliding grooves, the liquid collecting box 4 can be inserted or drawn out from the side. One end of the rectangular hole 11 is set to be open, which is convenient for the liquid collecting box 4 to be inserted. When the liquid collecting box 4 is inserted in place, the peripheries of the liquid collecting groove 13 and the rectangular hole 11 are aligned.

[0029] In this embodiment, a hand - grasping groove 5 is provided at the outer end of the liquid collecting box 4, and a grasping plate 14 is provided at the top of the hand - grasping groove 5. Through such a setting, it is convenient for fingers to reach into the hand - grasping groove 5 to hold the grasping plate 14 when extracting the liquid collecting box 4.

[0030] In this embodiment, in order to further provide a support protrusion structure, the support protrusion includes support blocks 10 provided at four corner positions of the limiting groove 15.

[0031] In this embodiment, in order to further provide a support protrusion structure, the support protrusion further includes a plurality of support cylinders 9 provided on both sides of the rectangular hole 11.
