Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses PVC micelle quality testing is with constant temperature and humidity case. Referring to fig. 1, a PVC micelle quality testing is with constant temperature and humidity case includes cabinet body 1, layer board 2 and conflict piece 3. Wherein, the cabinet body 1 can be the cuboid cabinet body 1, and the cabinet body 1 is provided with the holding

tank

11, and 11 openings of holding tank are articulated to have a door body 12, and door body 12 can open and shut for the cabinet body 1, and door body 12 has the visual window. The holding tank 11 is for holding a sample.

The supporting plate 2 can be arranged in the accommodating groove 11 in a sliding mode, and the accommodating groove 11 supports a sample through the supporting plate 2. The supporting plate 2 is provided with a plurality of through holes arranged at intervals so as to be convenient for keeping humidity. In order that the sample cannot be separated from the edge of the supporting plate 2 in the process of placing the sample, the edge of the supporting plate 2 is provided with a flange 21, and the flange 21 can prevent the sample to be detected from falling off. In the present embodiment, the flange 21 is disposed along the circumferential direction of the pallet 2, and the pallet 2 and the flange 21 may be welded or integrally connected.

To facilitate the sliding of the pallet 2 within the receiving groove 11, to extend or retract the receiving groove 11. The bottom of the supporting plate 2 is provided with a groove 22, and the length direction of the groove 22 is consistent with the depth direction of the accommodating groove 11. Correspondingly, the cabinet body 1 is connected with the supporting plate 2 in a sliding manner through the sliding rail 4. The sliding rail 4 is provided with a protrusion 41 corresponding to the groove 22, and the length of the protrusion 41 can be consistent with that of the sliding rail 4, so that the separation of the supporting plate 2 from the sliding rail 4 can be reduced in the sliding process of the supporting plate 2. In the present embodiment, in order to enable the supporting plate 2 to be smoothly installed in the cabinet 1, the number of the grooves 22 is two, and the grooves are arranged in parallel at intervals. Correspondingly, one supporting plate 2 corresponds to two sliding rails 4, and the sliding rails 4 can be fixedly installed or detachably installed in the accommodating grooves 11.

Because the slide rail 4 is likely to be in the sliding process, the protrusion 41 is worn and the like, and needs to be replaced or maintained, in this embodiment, the slide rail 4 and the accommodating groove 11 are detachably connected so as to be convenient to detach. Specifically, the side wall of the slide rail 4 is provided with a clamping block 42, and the clamping block 42 is fixedly connected with the slide rail 4, for example, welded or integrally formed. Correspondingly, the inner wall of the accommodating groove 11 is provided with a clamping groove 111, and the clamping block 42 is clamped with the clamping groove 111 to realize the clamping of the slide rail 4 and the inner wall of the accommodating groove 11. The number of the clamping blocks 42 is two, and the clamping blocks are respectively arranged on the slide rail 4 along the length direction of the slide rail 4 at intervals. In order to facilitate the alignment of the clamping blocks 42 with the corresponding clamping grooves 111 during the installation of the slide rail 4. The end of the clamping block 42 away from the slide rail 4 is provided with a first magnet 43, and correspondingly, the bottom of the clamping groove 111 is provided with a second magnet (not shown in the figure), and the first magnet 43 and the second magnet attract each other magnetically.

Referring back to fig. 1, in order to increase the utilization ratio in the holding tank 11, the quantity of layer board 2 is more than two, because the size of sample is different, so in order to use the space in the holding tank 11 more in a flexible way, the quantity of joint groove 111 is a plurality of, and sets up along the direction of height interval of the cabinet body 1, can carry out the joint through slide rail 4 and different joint groove 111, with the position of adjusting slide rail 4, install on slide rail 4 when layer board 2, can make the position of layer board 2 remove.

In order to prevent the supporting plate 2 from being separated from the cabinet body 1, the cabinet body 1 is provided with the abutting part 3, the abutting part 3 is detachably arranged in the accommodating groove 11, and when the abutting part 3 abuts, the abutting part 3 abuts against one side of the supporting plate 2 close to the opening of the accommodating groove 11 to prevent the supporting plate 2 from being separated from the cabinet body 1. Specifically, the abutting member 3 includes a threaded section (not shown) and an abutting section 31, and the abutting member 3 is in threaded connection with the cabinet 1 through the threaded section. When the abutting member 3 rotates, the threaded section drives the abutting section 31 to rotate, so that the abutting section 31 is located at the first position and the second position. When the abutting section 31 is located at the first position, the abutting section 31 abuts against the supporting plate 2, as shown in fig. 1, the rows 1 and 4 of the abutting pieces 3 are the same. When the collision section 31 is at the second position, the length direction of the collision section 31 is the same as the height direction of the cabinet 1, such as the 2 nd and 3 rd rows of the collision members 3 from top to bottom in fig. 1. The screw thread section can be dismantled with conflict section 31 and be connected, and connected mode is the joint, and conflict section 31 is provided with the groove promptly, and the screw thread section keeps away from one side and the groove joint of the cabinet body 1.

The implementation principle of PVC micelle quality testing constant temperature and humidity case is: when carrying out the sample aging test that awaits measuring, slide layer board 2, make layer board 2 roll-off holding tank 11, place the sample that awaits measuring on layer board 2, because when placing, layer board 2 is located holding tank 11 outer, so need not to stretch into holding tank 11 with the hand placing the in-process, reduce the danger that the staff scalded. After the placement is completed, the supporting plate 2 is slid into the receiving groove 11, and the abutting piece 3 is rotated, so that the abutting section 31 is located at the first position to prevent the supporting plate 2 from being separated from the receiving groove 11. When the space height above the height supporting plate 2 of the sample is not matched, the height of the supporting plate 2 can be determined by clamping the slide rail 4 with different clamping grooves 111 to adjust the position of the slide rail 4.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
