Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, specifically to a test rack and a test chamber. Background Technology

[0002] The test chamber is used to simulate climatic environmental conditions, under which test samples can be subjected to relevant tests. The test rack, an integral part of the test chamber, is located inside the chamber and is used to support the test samples during testing. The test chamber has a door; when the door is open, the test samples are placed on the test rack; when the door is closed, a relatively enclosed space is formed inside the chamber for conducting relevant tests. The test rack typically includes a bracket and a grid. The bracket is fixed to the inner wall of the chamber and supports the grid, which is placed on the test bracket. Test samples can then be placed on the grid for relevant tests.

[0003] Existing testing racks typically involve operators manually assembling the grid trays and placing test samples onto the rack. This isn't an issue for lighter samples, but as test samples become larger and testing chambers increase in height and multi-layer design to reduce laboratory space requirements, the process often involves placing the test sample on the grid tray first, then using a forklift to move both the tray and sample onto the support. However, with current racks, placing the grid tray onto the support using a forklift instead of manual labor, and due to the considerable height, often restricts the operator's view, requiring multiple attempts to align the tray correctly, thus impacting operational efficiency.

[0004] Therefore, there is an urgent need to provide a test rack and test chamber to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This embodiment provides a test chamber for simulating climatic environmental conditions, under which test samples can undergo relevant tests. Specifically, such as... Figure 1 As shown, the test chamber includes a chamber body 20, a door, and a test rack 10. The test rack 10 is fixed inside the chamber body 20 and is used to hold the test samples during testing. The door is rotatably located on one side of the chamber body 20. When the door is open, the test samples are placed on the test rack 10. When the door is closed, a relatively enclosed space is formed inside the test chamber, allowing for the implementation of relevant tests. For example... Figure 2 As shown, the test rack 10 includes a bracket 1 and a grid plate 2. The bracket 1 is fixed to the inner wall of the box 20 and is used to support the grid plate 2, while the grid plate 2 is placed on the bracket 1. Test samples can be placed on the grid plate 2 for relevant tests.

[0036] The existing test rack 10 typically involves operators assembling the grid 2 and placing the test sample onto the rack 10 by hand. This is not a problem for lighter samples. However, with the increasing size of test samples and the need to reduce laboratory space requirements, test chambers are becoming more multi-layered and taller. In this case, the test sample is often placed on the grid 2 first, and then a forklift is used to lift the grid 2 and test sample together onto the bracket 1. Currently, when placing the grid 2 onto the bracket 1, because it is done by forklift instead of by hand, and because the placement height is relatively high, the operator's line of sight is often limited, requiring multiple attempts to align the grid 2 correctly onto the bracket 1, thus affecting work efficiency.

[0037] To address the aforementioned problems, in this embodiment, in combination with Figure 2 and Figure 3 The bracket 1 includes a crossbeam 11 and a guide part 12. The crossbeam 11 can be connected to the left and right sides inside the housing 20 and is used to support the edge of the grid plate 2. The guide part 12 is fixedly connected to the crossbeam 11. The guide part 12 is provided with a guide slope 123. The guide slope 123 gradually slopes from top to bottom towards the grid plate 2. When the grid plate 2 is assembled, it can fall into the preset position of the crossbeam 11 along the guide slope 123.

[0038] In use, the test sample is first placed on the grid plate 2, and then a forklift is used to place the grid plate 2 onto the crossbeam 11. During the placement of the grid plate 2 by the forklift, the grid plate 2 can quickly and smoothly fall into the preset position on the crossbeam 11 along the guide slope 123 of the guide part 12, so that the crossbeam 11 supports the edge of the grid plate 2. Therefore, through the guiding action of the guide part 12, the forklift can easily and quickly place the grid plate 2 in the correct position on the crossbeam 11, improving work efficiency.

[0039] Optionally, the bracket 1 inside the test chamber can be set as one layer, or as two, three or more layers, so that the test chamber can be developed towards multiple layers and increased height. The specific number of layers can be flexibly set according to actual needs, and no specific limitation is made here.

[0040] Specifically, combined Figure 2 and Figure 3 In this embodiment, the crossbeam 11 is divided into a left crossbeam 101 and a right crossbeam 102, which are located on the left and right sides of the box 20, respectively. Each crossbeam 11 is L-shaped and includes a horizontal side 111 and a vertical side 112 that are vertically connected. The vertical side 112 is fixed to the inner wall of the box 20, and the horizontal side 111 is used to support the edge of the grid plate 2. The guide part 12 includes two guide plates 121, each of which is provided with a guide slope 123. The two guide plates 121 are located on the left crossbeam 101 and the right crossbeam 102, respectively. The guide plates 121 extend in the front-back direction, and two of their sides are respectively attached to and fixed to the inner surfaces of the horizontal side 111 and the vertical side 112. The guide slope 123 of the guide plate 121 faces the grid plate 2 so as to guide the grid plate 2 in the left-right direction when it is placed and dropped. Optionally, the cross-section of the guide block 122 is a right triangle or a right trapezoid, and the two right-angled sides of the guide plate 121 are respectively attached to the inner surfaces of the horizontal side 111 and the vertical side 112.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, the guide section 12 also includes guide blocks 122, each with a guide ramp 123. Two guide blocks 122 are provided on each crossbeam 11, with the two guide blocks 122 on each crossbeam 11 located on the front and rear sides of the guide plate 121, respectively. The guide ramp 123 of each guide block 122 faces the grid plate 2. The cross-section of the guide block 122 can be a right triangle or a right trapezoid, with the guide ramp 123 facing the grid plate 2 to guide the grid plate 2 in the front-back direction during its placement and descent.

[0042] Optionally, the crossbeam 11 can be fixedly connected to the guide plate 121 and the guide block 122 by means of bonding, welding or other fixed connection methods, without specific limitations.

[0043] Optionally, such as Figure 2 As shown, the bracket 1 also includes multiple uprights 13, each upright 13 being fixedly connected to the inner wall of the housing 20, and each crossbeam 11 being vertically connected to the corresponding upright 13. In this embodiment, the bracket 1 includes four uprights 13, which are arranged in a square array and connected to the four corners of the crossbeam 11. The crossbeam 11 can be transitionally connected to the inner wall of the housing 20 through the uprights 13, which can increase the load-bearing capacity of the test rack 10.

[0044] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the column 13 is a tube, and multiple mounting holes 131 are provided on the column 13, which are spaced vertically and communicate with the tube cavity. The crossbeam 11 is provided with a hanging head 14, which can be hung in the mounting hole 131 at the corresponding height. The distance between two adjacent mounting holes 131 on a single column 13 is short, and the number of mounting holes 131 is large, so the crossbeam 11 can be installed at different heights to meet the needs of placing the grid plate 2 at different heights in the test chamber.

[0045] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the mounting hole 131 includes a large hole 1311 and a small hole 1312 located below the large hole 1311 and connected to it. The hanger 14 includes a cap 141 and a rod 142. One end of the rod 142 is connected to the vertical edge 112 of the crossbeam 11, and the other end of the rod 142 is coaxially connected to the cap 141. The diameter of the cap 141 is larger than the diameter of the rod 142 but smaller than the diameter of the small hole 1312, so it cannot pass through the small hole 1312. The cap 141 can pass through the large hole 1311, and the rod 142 can fall into the small hole 1312. When installing the grid plate 2, the cap 141 is first passed through the large hole 1311, and then the grid plate 2 is lowered as a whole, so that the rod 142 falls into the small hole 1312, thereby facilitating the installation and removal of the crossbeam 11.

[0046] Optionally, such as Figure 2 As shown, the grid 2 includes a grid body 21 for carrying the test sample. The grid body 21 has a hollow structure so that the airflow above and below the grid 2 can convect, thereby ensuring the uniformity of temperature inside the test chamber.

[0047] Optionally, the grid body 21 is made of FR4 epoxy fiberglass board. FR4 epoxy fiberglass board still has high mechanical strength at 150℃ and has good insulation properties, making it suitable for testing electronic products.

[0048] Furthermore, such as Figure 2 As shown, the grid disk 2 also includes a frame 22 for supporting the grid disk body 21, with the grid disk body 21 fixedly connected to the upper side of the frame 22. The frame 22 supports the grid disk body 21, thereby increasing the overall load-bearing capacity of the grid disk 2. In this embodiment, the frame 22 is welded from square tubing. Square tubing is readily available and inexpensive, and welding square tubing into the frame 22 is also easy to manufacture.

[0049] Optionally, such as Figure 4As shown, a limiting rod 3 is provided at the bottom of the grid 2 on the side away from the test chamber door, extending in the left-right direction. The side away from the test chamber door refers to the rear side in the figure. It is understandable that, due to the forklift forks inserting too deeply, sometimes exceeding the boundary of the grid 2, the forklift forks may impact the interior of the housing 20 when placing the grid 2, causing damage to the inner wall of the housing 20 and affecting the quality of operation. Therefore, by providing the limiting rod 3 on the grid 2, the insertion depth of the forklift forks can be prevented from exceeding the width of the grid 2, thereby avoiding damage to the housing 20 by the forklift forks.

[0050] In an optional embodiment, such as Figure 4 As shown, a buffer pad 4 is provided on the side of the grid 2 away from the chamber door. When the forklift places the grid 2, the buffer pad 4 can buffer the force of the grid 2 directly colliding with the inner wall of the chamber 20. In this embodiment, the buffer pad 4 is made of silicone foam board. In other optional embodiments, the buffer pad 4 can also be made of other materials, as long as the above purpose can be achieved.

[0051] Optionally, the bottom of the grid 2 is provided with multiple spaced supports 5, which can support the ground. The supports 5 can support the grid 2 to a certain height when it is placed on the ground, thus providing space for the forks to insert into the bottom of the grid 2 when it needs to be lifted by a forklift. In this embodiment, the supports 5 are bolts, which are readily available. One end of the bolt shank is directly welded to the frame 22, and the other end of the bolt head is used to contact the ground, providing a large support surface.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
