[0017] Figure 1 It is a three-dimensional diagram of a movable sample rack of a VOC chamber according to an embodiment of the utility model. DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0019] First, combine Figure 1 The movable sample rack for a VOC chamber according to an embodiment of the utility model is described, which is used to carry objects to be tested and has a wide range of application scenarios.

[0020] like Figure 1 As shown, the VOC chamber movable sample rack of the embodiment of the utility model comprises: a fixed bracket 1, a pair of guide rails 2, a movable bracket 3 and a displacement assembly;

[0021] Specifically, Figure 1 As shown, a fixed bracket 1 is arranged at the bottom of the VOC cabin; a pair of guide rails 2 are arranged in parallel on the top of the fixed bracket 1 for guiding the mobile bracket 3; the mobile bracket 3 is slidably arranged on the top of the pair of guide rails 2 for carrying external VOC test samples (not shown in the figure), and the mobile bracket 3 can extend out of the VOC cabin door, which is convenient for users to place VOC test samples, reduces the difficulty of carrying VOC test samples, reduces the labor cost of the experiment, improves the safety factor, solves the defect of the prior art that the VOC test samples need to be placed in the VOC cabin, avoids contamination of the internal environment of the VOC cabin, and reduces experimental errors; the displacement component is clamped at the bottom of the mobile bracket 3, and the displacement component is located at one end of the mobile bracket 3 for supporting the mobile bracket 3.

[0022] Further, if Figure 1As shown, the displacement assembly includes: a pair of load-bearing columns 41 and a pair of universal wheels 42; the pair of load-bearing columns 41 are symmetrically clamped on the bottom of the mobile bracket 3, and the pair of load-bearing columns 41 are located at one end of the mobile bracket 3. When the mobile bracket 3 is completely located in the VOC cabin, the user needs to remove the pair of load-bearing columns 41 and the pair of universal wheels 42 to avoid polluting the internal environment of the VOC cabin and reduce experimental errors; the pair of universal wheels 42 are respectively arranged at the bottom of the pair of load-bearing columns 41, which enhances the load-bearing capacity of this embodiment and improves the safety factor of this embodiment.

[0023] Further, if Figure 1 As shown, the VOC chamber movable sample rack also includes: a plurality of pairs of rollers 5, which are rotatably arranged on the top of a pair of guide rails 2, and the tops of the plurality of pairs of rollers 5 abut against the bottom of the movable bracket 3, thereby reducing the friction between the movable bracket 3 and the guide rail 2.

[0024] Further, if Figure 1 As shown, several pairs of rollers 5 are graphene bearings, which do not require lubrication with lubricating oil, thereby avoiding contamination of the internal environment of the VOC cabin and reducing experimental errors.

[0025] Further, if Figure 1 As shown, the VOC cabin movable sample rack also includes: a pair of limit members 6, the pair of limit members 6 are symmetrically arranged on the side walls on both sides of the movable bracket 3, and the pair of limit members 6 are respectively matched with the positions of the frame on both sides of the door of the VOC cabin, which are used to limit the travel of the movable bracket 3 and prevent the movable bracket 3 from escaping from the pair of guide rails 2, thereby improving the safety factor of this embodiment.

[0026] Further, if Figure 1 As shown, the VOC chamber movable sample holder further comprises: a plurality of through holes 7, and the plurality of through holes 7 are evenly distributed on the top of the movable bracket 3, so that the VOC test sample is fully exposed to the environment in the VOC chamber, thereby improving the accuracy of the experiment.

[0027] When the user applies the present embodiment to carry the VOC test sample, first, the user pulls the mobile bracket 3 out of the VOC cabin for a distance and installs a pair of load-bearing columns 41 at the bottom of the mobile bracket 3 and then pulls the mobile bracket 3 out completely. During the movement of the mobile bracket 3, the roller 5 in contact with the mobile bracket 3 rolls to reduce the resistance encountered by the mobile bracket 3 during the movement. When the mobile bracket 3 is pulled out for a certain distance, the pair of limit members 6 interfere with the hatch of the VOC cabin to prevent the mobile bracket 3 from escaping from the guide rail 2. After the mobile bracket 3 is fully pulled out, the user places the VOC test sample on the top of the mobile bracket 3. After placing the VOC test sample, the user pushes the mobile bracket 3 back for a distance. Finally, the user removes the pair of support columns and then pushes the mobile bracket 3 back to its initial position completely.

[0028] Above, refer to Figure 1 The present invention discloses a movable sample rack for a VOC chamber according to an embodiment of the present invention, which solves the defect in the prior art that the user needs to enter the VOC chamber to place the VOC test sample. The rack has the characteristics of being easy to use, having a strong carrying capacity and a high safety factor, and reduces the labor cost of the experiment.
