Description

Technical Field

[0001] This utility model relates to the field of test chamber accessories, and in particular to an adjustable height anti-tipping grate. Background Technology

[0002] A test chamber is a widely used device in fields such as biology, medicine, and agriculture. It is used to provide suitable environmental conditions to promote the growth and reproduction of biological samples such as microorganisms, plants, and animal cells. Traditional test chambers usually consist of a closed chamber with temperature control, humidity control, and ventilation devices to simulate different growth environments.

[0003] However, traditional test chambers have some technical problems during use. On the one hand, as experimental needs change, it is necessary to stratify or adjust the height of the items inside the test chamber. However, the internal structure of traditional test chambers is relatively fixed and it is difficult to meet such flexible adjustment needs. On the other hand, when taking out or placing items inside the test chamber, due to the lack of effective positioning and limiting devices, items are prone to tilting or even tipping over, leading to experimental failure or sample damage. Utility Model Content

[0004] To address the problem that traditional installation methods in existing technologies are often inconvenient and unstable, affecting the efficiency and accuracy of experiments, this utility model provides an adjustable height anti-tipping grate.

[0005] The adjustable height anti-tipping grate provided by this utility model adopts the following technical solution:

[0006] An adjustable height anti-tipping grate, characterized in that it includes four anti-tipping supports, which are vertically arranged at the four corners of the inner liner of a test chamber. The outer side wall of each anti-tipping support has several mounting holes. An anti-tipping shelf is movably installed between the mounting holes on the same horizontal line of two anti-tipping supports on the same side. A grate plate is placed on the top of the anti-tipping shelf. A limiting plate is welded to the outer side wall of the anti-tipping shelf to ensure that the grate plate can always be pulled out horizontally.

[0007] Furthermore, the number of mounting holes on the outer side wall of each anti-overturning support is the same and they correspond one-to-one, and the spacing between the mounting holes on the same anti-overturning support is equal.

[0008] Furthermore, the anti-tipping shelf has an L-shaped structure, and one side wall of the anti-tipping shelf is formed by stamping hooks for hanging the anti-tipping shelf in the mounting hole; the other side wall of the anti-tipping shelf is used to place the grate plate.

[0009] Furthermore, the limiting plate has an L-shaped structure; one side wall of the limiting plate is welded to the side wall of the anti-tipping shelf with a hook; the other side wall of the limiting plate is parallel to the side wall of the anti-tipping shelf where the grate is placed, and a channel is formed between them that allows the grate to be pulled horizontally, the width of which is equal to the thickness of the grate.

[0010] Furthermore, the mounting hole includes an embedding hole and a limiting hole; both the embedding hole and the limiting hole are rectangular holes and are interconnected; the limiting hole is located at the lower apex corner of the embedding hole.

[0011] Furthermore, the size of the embedding hole allows the hook to be inserted directly horizontally;

[0012] Furthermore, the size of the limiting hole allows the hook to tilt and slide in after being inserted into the embedding hole and hooked downwards.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] This invention features four vertical anti-tipping supports with mounting holes on their outer walls, allowing for adjustable grate height in conjunction with the anti-tipping rack. A grate plate is placed on top of the anti-tipping rack to support and separate items within the test chamber. A limiting plate is welded to the outer wall of the anti-tipping rack, ensuring the grate plate can always be pulled horizontally, effectively preventing tipping after partial removal from the chamber. Furthermore, the L-shaped structure of the anti-tipping rack, with its hooks engaging the mounting holes, makes installation simple and quick. The design of the embedding holes and limiting holes enhances the stability of the anti-tipping rack installation, effectively preventing it from detaching from the mounting holes during use and improving overall stability.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail below:

[0021] This utility model discloses an adjustable height anti-tipping grate, such as... Figure 1 As shown, an adjustable height anti-tipping grate is characterized by comprising four anti-tipping supports 2, which are vertically arranged at the four corners of the inner liner 1 of the test chamber. The outer side walls of the anti-tipping supports 2 have several mounting holes 21. An anti-tipping shelf 3 is movably installed between the mounting holes 21 on the same horizontal line of two anti-tipping supports 2 on the same side. A grate plate 4 is placed on top of the anti-tipping shelf 3. A limiting plate 32 is welded to the outer side wall of the anti-tipping shelf 3 to ensure that the grate plate 4 is always horizontally pulled out. In this embodiment, the four anti-tipping supports 2 are vertically arranged... The four corners of the inner chamber 1 of the test chamber serve as the supporting foundation for the entire grate structure. Several mounting holes 21 on the outer wall of the anti-tipping support column 2 are used to install the anti-tipping shelf 3. The anti-tipping shelf 3 is installed between two mounting holes 21 on the same horizontal line to provide a platform for placing the grate plate 4. The limiting plate 32 is welded to the outer wall of the anti-tipping shelf 3 to limit the pulling direction of the grate plate 4 and ensure that it is always pulled horizontally. This prevents the grate plate 4 from tilting or tipping over during the pulling process, improving the safety and convenience of use.

[0022] like Figure 2 As shown, the number of mounting holes 21 on the outer wall of each anti-tipping support 2 is the same and they correspond one-to-one. At the same time, the spacing between the mounting holes 21 on the same anti-tipping support 2 is equal. In this embodiment, when installing the anti-tipping shelf 3, since the mounting holes 21 correspond and the spacing is equal, the anti-tipping shelf 3 only needs to be accurately aligned with two mounting holes 21 on the same horizontal line to complete the installation. No additional adjustment is required to ensure the levelness of the anti-tipping shelf 3. This ensures that the anti-tipping shelf 3 can remain level when installed at different heights, thereby ensuring the horizontal placement of the grate plate 4, which is beneficial for the stable placement and operation of items in the test chamber.

[0023] like Figure 3 As shown, the anti-tipping shelf 3 has an L-shaped structure. One side wall of the anti-tipping shelf 3 is formed by stamping hooks 31, which are used to hang the anti-tipping shelf 3 in the mounting hole 21. The other side wall of the anti-tipping shelf 3 is used to place the grate plate 4. In this embodiment, the anti-tipping shelf 3 adopts an L-shaped structure. One side wall is formed by stamping hooks 31, which are used to hang the anti-tipping shelf 3 in the mounting hole 21, realizing the connection between the anti-tipping shelf 3 and the anti-tipping support 2. The other side wall is used to place the grate plate 4, providing a flat placement platform. The L-shaped structure design allows the anti-tipping shelf 3 to be easily connected to the anti-tipping support 2 and to provide a stable placement platform for the grate plate 4. The design of the hooks 31 is simple and practical. The stamping process can ensure the strength and stability of the hooks 31, so that the anti-tipping shelf 3 can be firmly hung in the mounting hole 21 and is not easy to fall off.

[0024] like Figure 2 As shown, the limiting plate 32 has an L-shaped structure; one side wall of the limiting plate 32 is welded to the side wall of the anti-tipping shelf 3 where the hook 31 is provided; the other side wall of the limiting plate 32 is parallel to the side wall of the anti-tipping shelf 3 where the grate plate 4 is placed, and a channel is formed between them to allow the grate plate 4 to be pulled horizontally. The width of the channel is equal to the thickness of the grate plate 4. In this embodiment, this design allows the grate plate 4 to be pulled horizontally only within the channel, restricting its movement in other directions, thereby ensuring the horizontal pulling of the grate plate 4. The setting of the limiting plate 32 effectively prevents the grate plate 4 from tilting or overturning during the pulling process. When a part of the grate plate 4 is pulled out, due to the restriction of the channel, the grate plate 4 can only move in the horizontal direction and will not overturn due to the shift of the center of gravity, thus improving the safety and stability of use.

[0025] like Figure 4 As shown, the mounting hole 21 includes an insertion hole 211 and a limiting hole 212; both the insertion hole 211 and the limiting hole 212 are rectangular holes and are interconnected; the limiting hole 212 is located at the lower apex corner of the insertion hole 211; the size of the insertion hole 211 allows the hook 31 to be inserted horizontally directly; the size of the limiting hole 212 allows the hook 31 to slide in at an angle after being inserted into the insertion hole 211 and hooked downwards. In this embodiment, the hook 31 is first horizontally inserted into the embedding hole 211, and then the anti-tipping shelf 3 is hung downwards, so that the hook 31 slides into the limiting hole 212 at an angle, thus completing the installation of the anti-tipping shelf 3. The size of the embedding hole 211 allows the hook 31 to be directly inserted horizontally, which facilitates the initial installation of the anti-tipping shelf 3. The setting of the limiting hole 212 allows the hook 31 to slide into the embedding hole 211 at an angle after it is inserted and hung downwards, further fixing the anti-tipping shelf 3 and preventing the anti-tipping shelf 3 from coming out of the mounting hole 21 during use, thereby improving the stability of the installation of the anti-tipping shelf 3.

[0026] During installation, first align the hook 31 with the insertion hole 211, and push the anti-tipping shelf 3 horizontally so that the hook 31 is inserted into the insertion hole 211. After the hook 31 is inserted into the insertion hole 211, hang the anti-tipping shelf 3 downward so that the hook 31 tilts and slides into the limiting hole 212.
