Description

Technical Field

[0001] This utility model relates to the field of test chamber technology, and in particular to a walk-in test chamber body. Background Technology

[0002] Currently, in order to ensure good sealing of the large walk-in test chamber, the chamber is usually assembled by welding. That is, the smaller panels that make up the walk-in test chamber are first transported to the required test location, and then the panels are welded together at the test location to form the walk-in test chamber.

[0003] However, the following problems arise from using the above-mentioned welding assembly method to form the walk-in test chamber: 1) It makes it impossible to disassemble and move individual panels of the walk-in test chamber, resulting in the entire walk-in test chamber being unable to be moved and reused, leading to a low reuse rate; 2) Since on-site welding is required at the test location, a welding gas source needs to be prepared, which makes on-site assembly management difficult and poses certain safety hazards and environmental pollution from welding fumes during the welding process; 3) This welding assembly method is not suitable for situations with high requirements for the assembly environment at the test location and limited welding space at the test location, resulting in poor applicability and versatility of the entire walk-in test chamber. Utility Model Content

Each upright plate includes at least two adjacent, sequentially sealed and abutting sub-plates, with the opposite ends of each sub-plate connected to a bottom plate and a top plate along the Z-axis, respectively. A locking protrusion is provided on one of the upright plates and the bottom plate, and a locking groove is provided on the other. A groove communicating with the groove is provided within the groove, and a flexible sealing plate is provided within the groove.

Detailed Implementation

[0044] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] This embodiment provides a walk-in test chamber housing. The walk-in test chamber housing has a simple structure, low requirements for the assembly environment, and high assembly safety. It does not cause smoke pollution during the assembly process, reducing the difficulty of on-site management of the assembly environment. Furthermore, the walk-in test chamber housing can be easily and non-destructively disassembled after assembly and use, thereby ensuring the secondary handling and use of the walk-in test chamber housing and improving the reusability of the entire walk-in test chamber housing.

[0049] It is worth noting that because staff can directly enter the interior of the walk-in test chamber to work, the entire chamber is quite large. Therefore, each panel of the walk-in test chamber needs to be transported to the assembly site before assembly. When the chamber needs to be moved to another assembly site for reassembly after use, each panel must be disassembled without damage. Then, smaller panels can be easily moved to the other assembly site for reassembly. This ensures the walk-in test chamber can be disassembled without damage, moved again, and reused.

[0050] Specifically, such as Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the walk-in test chamber includes a base plate 1, a top plate, four upright plates 3, a flexible sealing plate 4, L-shaped fasteners 5, fasteners 6, and locking components. The four upright plates 3 are arranged in a square, sequentially sealing and abutting each other to ensure a tight seal between adjacent upright plates 3. Each upright plate 3 includes at least two parallel, sealed sub-plates 31 to ensure a tight seal between the sub-plates 31. The sub-plates 31 are connected to the base plate 1 and the top plate at opposite ends along the Z-axis to form the walk-in test chamber. Furthermore, the connection structure between the sub-plate 31 and the top plate is the same as the connection structure between the sub-plate 31 and the base plate 1. At one of the upright plates 3 and the base plate 1... One plate has a protrusion 311 on one side and a groove 11 on the other. The groove 11 has a channel 111 communicating with it. Both the channel 111 and the groove 11 extend along the X-axis. A flexible sealing plate 4 is provided in the channel 111. When the protrusion 311 is engaged in the groove 11, it presses against the flexible sealing plate 4. An L-shaped fastener 5 is provided at the connection position between the base plate 1 and the upright plate 3. One end of the L-shaped fastener 5 is connected to the base plate 1, and the other end abuts against the first side 312 of the partition plate 31. A fastener 6 is provided between the base plate 1 and the partition plate 31. The fastener 6 is used to fasten the base plate 1 and the partition plate 31. A locking member is connected between two adjacent partition plates 31. The locking member is used to lock the two adjacent partition plates 31.

[0051] Compared with the prior art, the walk-in test chamber in this embodiment changes the specific layout and connection method between the various structures. It arranges four upright plates 3 in a square, sequentially sealed and abutting configuration. Each upright plate 3 includes at least two adjacent, sealed and abutting sub-plates 31, with the opposite ends of the sub-plates 31 connected to the bottom plate 1 and the top plate along the Z-axis, respectively. Furthermore, a locking protrusion 311 is provided on one of the upright plates 3 and the bottom plate 1, and a locking groove 11 is provided on the other. A groove 111 communicating with the groove 11 is provided within the groove 111, and a flexible sealing plate 4 is provided within the groove 111. When the locking protrusion 311 is engaged within the groove 11, the locking protrusion 311... It can press against the flexible sealing plate 4 to achieve a sealed connection between the partition plate 31 and the base plate 1; and one end of the L-shaped fastener 5 is connected to the base plate 1, while the other end of the L-shaped fastener 5 abuts against the first side 312 surface of the partition plate 31. The L-shaped fastener 5 provides stable support for the connection between the base plate 1 and the upright plate 3, thereby ensuring the stability of the connection between the base plate 1 and the upright plate 3; then, the base plate 1 and the partition plate 31 are fastened together by the fastener 6 to ensure the tightness of the connection between the base plate 1 and the partition plate 31; and the two adjacent partition plates 31 are locked by the locking member to ensure the stability and sealing of the connection between the two partition plates 31; that is, the upper The aforementioned method employs a series of mutually cooperating components, including a latch 311, a slot 11, a flexible sealing plate 4, an L-shaped fastener 5, fasteners 6, and locking elements, to stably connect the four upright plates 3 to the base plate 1. Furthermore, since the connection structures between the upright plates 31 and the top plate are identical, and between the upright plates 31 and the base plate 1, the four upright plates 3 can be stably connected to the top plate via these connection structures, thereby assembling a walk-in test chamber body with good structural stability and sealing effect. The entire walk-in test chamber body is assembled using various mechanical connection structures, which has the following advantages compared to the welding assembly method used in existing technologies: 1) It can facilitate the assembly of the walk-in test chamber body... The individual panels (bottom panel 1, top panel, and sub-panel 31) of the walk-in test chamber can be dismantled and moved, allowing the entire chamber to be moved and reused, thus improving its reusability. 2) Since on-site welding is no longer required at the test location, there is no need to prepare a welding gas source, reducing the difficulty of managing the assembly site and eliminating safety hazards and environmental pollution from welding fumes. 3) The mechanical connection structure assembly method is suitable for situations with high assembly environment requirements at the test location and limited welding space, thereby improving the applicability and versatility of the entire walk-in test chamber.

[0052] And, as Figure 1 and Figure 4As shown, by including at least two sequentially arranged, sealed, and abutting sub-plates 31 in each upright plate 3, the entire upright plate 3 is divided into sub-plates 31 with smaller occupancy areas. This facilitates smooth transportation of the sub-plates 31 and avoids transportation difficulties caused by the large volume of the entire upright plate 3. Furthermore, to better ensure smooth transportation, the maximum size of each sub-plate 31 should be less than or equal to one meter. In this embodiment, each upright plate 3 includes two sub-plates 31. The specific number of sub-plates 31 included in the upright plate 3 needs to be determined based on the actual transportation conditions and assembly situation, and is not specifically limited here.

[0053] Furthermore, such as Figures 1 to 5 As shown, a locking protrusion 311 is provided at the bottom end of the partition plate 31, and the locking protrusion 311 penetrates the partition plate 31 along the X-axis; a locking groove 11 is provided at the top end of the base plate 1, and the locking groove 111 penetrates the base plate 1 along the X-axis, and a groove 111 penetrates the locking groove 11 along the X-axis. Along the Y-axis, there are two symmetrical grooves 111 in the locking groove 11, and a flexible sealing plate 4 is provided in each groove 111, so that the sealing effect between the partition plate 31 and the base plate 1 can be better guaranteed by simultaneously pressing the two flexible sealing plates 4.

[0054] Specifically, such as Figure 8 As shown, the groove depth of the groove 111 is H1, the thickness of the flexible sealing plate 4 is H2, and H2-H1=2±0.5mm, so that the locking protrusion 311 presses against the part of the flexible sealing plate 4 that protrudes outside the groove 111; for example, if the depth of the groove 111 is H1=3mm and the thickness of the flexible sealing plate 4 is H2=5mm, then H2-H1=2mm, so that after the flexible sealing plate 4 is installed into the groove 111, it will protrude 2mm outside the groove 111, so that the locking protrusion 311 can press against the protruding 2mm part to achieve a 2mm compression seal, thereby better ensuring the sealing effect between the partition plate 31 and the base plate 1.

[0055] Specifically, the flexible sealing plate 4 is made of a flexible material, such as silicone or foam, so that the flexible sealing plate 4 can deform flexibly during the pressing process, thereby allowing the flexible sealing plate 4 to fit tightly with the protrusion 311, thus ensuring the sealing effect of the flexible sealing plate 4 between the base plate 1 and the sub-plate 31.

[0056] Specifically, the flexible sealing plate 4 is glued into the groove 111, that is, the flexible sealing plate 4 is fixed in the groove 111 by applying glue, which makes the installation of the flexible sealing plate 4 simple and convenient, and the installation cost is low. At the same time, it can ensure the fixed installation effect of the flexible sealing plate 4 in the groove 111. Furthermore, it can facilitate the quick removal of the flexible sealing plate 4 from the groove 111 when it is necessary to replace the damaged flexible sealing plate 4, making the maintenance and replacement of the flexible sealing plate 4 simple and quick.

[0057] Furthermore, such as Figure 1 , Figure 2 and Figure 7 As shown, the L-shaped fastener 5 includes a horizontal plate 51 and a vertical plate 52. The horizontal plate 51 is placed horizontally on the top surface of the base plate 1. A fixing nut 12 is pre-embedded inside the base plate 1. A fixing bolt 511 passes downward along the Z-axis through the horizontal plate 51 and is threadedly tightened with the fixing nut 12, so that the horizontal plate 51 can be fixed to the top surface of the base plate 1 through the cooperation of the fixing nut 12 and the fixing bolt 511. The vertical plate 52 is vertically connected to the horizontal plate 51 to form the L-shaped fastener 5, and the vertical plate 52 abuts against the first side 312 of the partition plate 31. Specifically, the vertical plate 52 and the horizontal plate 51 can be an integral structure.

[0058] By setting up horizontal plates 51 and vertical plates 52 that cooperate with each other, the L-shaped fastener 5 can provide stable support for the connection between the base plate 1 and the vertical plate 3, thereby ensuring the connection stability between the vertical plate 3 and the base plate 1. Furthermore, multiple fixing bolts 511 / fixing nuts 12 are spaced apart along the X-axis, which further ensures the connection stability between the horizontal plate 51 and the base plate 1, thereby further improving the connection stability between the vertical plate 3 and the base plate 1. In this embodiment, a total of seven fixing bolts 511 and seven fixing nuts 12 are provided.

[0059] Specifically, the entire L-shaped fastener 5 is made of stainless steel, which ensures good structural strength, good wear resistance, excellent mechanical properties, and high-temperature resistance.

[0060] Specifically, such as Figure 5 and Figure 7As shown, the fastener 6 includes a fastening bolt 61 and a fastening nut 62. The fastening bolt 61 is pre-embedded inside the partition plate 31 near its second side 313. The first side 312 and the second side 313 of the partition plate 31 are arranged opposite each other along the Y-axis. The fastening nut 62 is rotatably connected to the base plate 1 and corresponds to the fastening bolt 61. The fastening nut 62 is threaded onto the fastening bolt 61, so that a stable connection between the partition plate 31 and the base plate 1 can be achieved through the locking of the fastening nut 62 on the fastening bolt 61, further ensuring the stability of the connection between the partition plate 31 and the base plate 1. Each partition plate 31 is locked to the base plate 1 by a fastening bolt 61 and a fastening nut 62.

[0061] Furthermore, such as Figure 9 As shown, the locking element includes a latch 71. A first part of the latch 71 is connected to the outer side of one of two adjacent partition plates 31, and a second part of the latch 71 is connected to the outer side of the other adjacent partition plate 31. The first part can rotate and latch onto the second part, thus connecting the two adjacent partition plates 31 together via the latch 71. This prevents the adjacent partition plates 31 from separating and ensures a sealing effect between them. Furthermore, multiple latches 71 can be spaced apart along the Z-axis between adjacent partition plates 31, with each latch 71 positioned in the middle of the partition plate 31 to better ensure the stability of the connection between adjacent partition plates 31. The latches 71 can employ a common latch structure found in existing technologies.

[0062] In addition, such as Figure 10 As shown, the locking component may further include a locking bolt 721 and a locking nut 722; wherein, the locking bolt 721 is pre-embedded in the interior of one of the two adjacent sub-plates 31; the locking nut 722 is rotatably connected to the other of the two adjacent sub-plates 31 and is correspondingly provided with the locking bolt 721, and the locking nut 722 is used to be threaded onto the locking bolt 721 so that a stable connection and sealing between the two adjacent sub-plates 31 can be achieved by locking the locking nut 722 onto the locking bolt 721; and, along the Z-axis, multiple locking bolts 721 / locking nuts 722 can be spaced apart between the two adjacent sub-plates 31, and each locking bolt 721 / locking nut 722 is provided in the middle part of the sub-plate 31 so as to better ensure the connection stability between the two adjacent sub-plates 31.

[0063] Furthermore, such as Figure 3 , Figure 6 , Figure 9 and Figure 10As shown, one of the two adjacent sub-plates 31 is provided with a positioning protrusion 314, and the other is provided with a positioning groove 315. The positioning groove 315 extends along the Z-axis, and the positioning protrusion 314 / positioning groove 315 penetrates the sub-plate 31 along the Z-axis. The positioning protrusion 314 can be positioned and engaged in the positioning groove 315, so as to quickly position and install the two adjacent sub-plates 31, thereby ensuring the speed and accuracy of installation between the two adjacent sub-plates 31.

[0064] Specifically, such as Figure 3 , Figure 6 , Figure 9 and Figure 10 As shown, two sealing strips 8 are provided between two adjacent partition plates 31. The sealing strips 8 extend along the Z-axis and are flush with the positioning protrusion 314 / positioning groove 315 along the Z-axis. The two sealing strips 8 are positioned opposite each other on both sides of the locking protrusion 311 along the Y-axis. That is, when the two sealing strips 8 are placed on either partition plate 31 and the positioning protrusion 314 is locked into the positioning groove 315, the two sealing strips 8 are sealed between the two adjacent partition plates 31. This can block the airflow between the inside and outside of the entire vertical plate 3 through the two sealing strips 8, thereby ensuring the airtightness of the entire walk-in test chamber.

[0065] Furthermore, such as Figure 7 , Figure 9 and Figure 10 As shown, the walk-in test chamber also includes a first eccentric hook 9 and a second eccentric hook 10. The first eccentric hook 9 is pre-embedded inside either of two adjacent partition plates 31, serving to secure the adjacent partition plates 31 and thus better ensure the connection stability and overall stability between them. The second eccentric hook 10 is pre-embedded inside the partition plate 31, serving to secure the partition plate 31 to the base plate 1, further ensuring the connection stability and overall stability between the partition plate 31 and the base plate 1. Both the first eccentric hook 9 and the second eccentric hook 10 can employ common eccentric hook structures found in existing technologies.

[0066] The specific assembly process of the walk-in test chamber in this embodiment is as follows. Taking the installation of one upright plate 3 (two sub-plates 31) onto the base plate 1 as an example, the process of installing the upright plate 3 onto the top plate can be referred to the following process:

[0067] First, the positioning protrusion 314 is positioned and snapped into the positioning groove 315 to quickly position and install two adjacent sub-plates 31; at this time, the two sealing strips 8 are sealed between the two adjacent sub-plates 31; then the first eccentric hook 9 is fixed and hooked into the two adjacent sub-plates 31; and the outer sides of the two adjacent sub-plates 31 are locked by the locking member; so as to connect and install the two adjacent sub-plates 31 to form a vertical plate 3.

[0068] Then, the protrusions 311 on the two plates 31 are respectively positioned and snapped into the slots 11 of the base plate 1 along the X-axis. At this time, the protrusions 311 press against the 2mm portion of the flexible sealing plate 4 that protrudes out of the groove 111 to seal the two plates 31 and the base plate 1.

[0069] Then, the second eccentric hook 10 is used to fix the sub-plate 31 and the base plate 1. The fastening nut 62 inside the base plate 1 is then tightened to the fastening bolt 61 embedded inside the sub-plate 31 to lock and fix the sub-plate 31 and the base plate 1. This process is repeated to lock and fix the other sub-plate 31 and the base plate 1.

[0070] At the same time, the fixing bolt 511 is passed down along the Z-axis through the horizontal plate 51 and screwed into the fixing nut 12 embedded in the base plate 1 to fix the horizontal plate 51 to the top surface of the base plate 1; and the vertical plate 52 is made to abut against the first side 312 of the sub-plate 31; so as to complete the fixed connection of one vertical plate 3 (two sub-plates 31) to the base plate 1.

[0071] Finally, repeat the above process to fix the remaining three upright plates 3 to the base plate 1, and fix the four upright plates 3 sub-plates 31 to the top plate to assemble and form the walk-in test chamber body.

[0072] When the assembled walk-in test chamber is used and needs to be moved to another required test location, the locking mechanism and the first eccentric hook 9 are released according to the above installation process. The positioning protrusion 314 is then slid out of the positioning groove 315 to disassemble and form two independent partition plates 31. The L-shaped fixing part 5 is then removed, and the connection between the second eccentric hook 10, the fastening nut 62, and the fastening bolt 61 is released. The locking protrusion 311 is then slid out of the locking groove 11 to separate the bottom plate 1 and the partition plates 31, thereby forming eight independent partition plates 31, the bottom plate 1, and the top plate. After all eight partition plates 31, the bottom plate 1, and the top plate are transported to other required test locations, the above installation process is repeated to reassemble the eight partition plates 31, the bottom plate 1, and the top plate to form the walk-in test chamber for use.

[0073] In this embodiment, the walk-in test chamber uses structural assembly and connection assembly instead of the welding method in the prior art. This makes the entire walk-in test chamber easier to install and portable, avoiding the safety hazards and difficulties in on-site safety management caused by welding machines, gases, and hot flashes. Furthermore, the entire installation and assembly process is simple and convenient.

[0074] The installation requires less skill and no professional welding personnel are needed. Furthermore, the walk-in test chamber, assembled using the aforementioned mechanical connection structure, can be easily disassembled and transported without damage after installation, increasing the overall reusability of the chamber. Moreover, the base plate 1, sub-plate 31, top plate, flexible sealing plate 4, sealing strip 8, locking components, fasteners 6, L-shaped fixing components 5, first eccentric hook 9, and second eccentric hook 10 are all designed as independent modular structures, which improves the overall production efficiency of the walk-in test chamber and reduces production costs.

[0075] 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.
