Description

Technical Field

[0001] This utility model belongs to the field of cleanroom technology, and in particular relates to a prefabricated cleanroom. Background Technology

[0002] Prefabricated clean booths are simple cleanroom devices with modular design. They form localized high-cleanliness environments by assembling prefabricated components on-site. They can be built and dismantled to adapt to different production needs. They are usually composed of a frame, lighting fixtures, enclosure and purification components, and are suitable for scenarios in industries such as electronics, pharmaceuticals and food where there are specific requirements for air cleanliness.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing prefabricated cleanrooms:

[0004] 1. The leveling structure at the bottom of the frame is easily rotated by non-staff members, which can cause the frame to be tilted under stress. It is not convenient to make the leveling structure a structure that can only be rotated with special tools to prevent it from being easily rotated.

[0005] 2. The frame uprights and crossbars need to be fixed with multiple bolts, which affects the efficiency of disassembly and assembly. It is inconvenient to set up an assembly structure on the frame to allow for quick disassembly and assembly of the frame uprights and crossbars. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a prefabricated cleanroom to solve the issues of existing frame bottom leveling structures being easily rotated by non-staff members, leading to frame skew and making it inconvenient to design the leveling structure as requiring special tools to rotate, thus preventing easy rotation; and the need for multiple bolts to fix the frame uprights and crossbars, affecting assembly and disassembly efficiency, making it inconvenient to set up assembly structures on the frame to allow for quick assembly and disassembly of the frame uprights and crossbars.

[0007] The purpose and effectiveness of this prefabricated cleanroom are achieved through the following specific technical means:

[0008] A prefabricated cleanroom includes a cleanroom wall; prefabricated uprights are provided on both the left and right sides of the cleanroom wall in a vertical direction; the bottom outer circumference of the prefabricated uprights is threaded; four downward-through dovetail grooves are arranged in a ring array on the bottom outer circumference of the prefabricated uprights; a leveling screw hole is provided at the center of the bottom end face of the prefabricated uprights; four upward-through strip grooves are arranged in a ring array on the outer circumference of the prefabricated uprights; a fixing screw hole is provided at the center of the top end face of the prefabricated uprights; four insertion blind holes are arranged in a ring array around the fixing screw hole of the prefabricated uprights; a vertically oriented leveling support column is installed inside the leveling screw hole of the prefabricated uprights; a ground-contact circular plate is provided at the bottom of the leveling support column; a regular triangular prism is provided on the top end face of the ground-contact circular plate of the leveling support column; and a threaded rod is provided on the top end face of the regular triangular prism of the leveling support column.

[0009] Furthermore, a locking pin is installed inside the fixing screw hole of the assembled upright, a threaded rod is provided at the lower part of the locking pin, a limit ring plate is provided on the outer circumference of the top of the threaded rod of the locking pin, and a regular hexagonal prism is provided on the top end face of the threaded rod of the locking pin.

[0010] Furthermore, a closed stabilizing rod is inserted into the blind hole between the assembled uprights. The bottom end face of the closed stabilizing rod is provided with an insertion post at both ends. The left and right end faces of the closed stabilizing rod are provided with trapezoidal heads. The top end face of the trapezoidal head of the closed stabilizing rod is provided with an arc-shaped fitting groove.

[0011] Furthermore, the assembly locking cylinder is threadedly installed on the outer circumference of the bottom of the assembled upright, the inner circumference of the assembly locking cylinder is threaded, and the outer circumference of the assembly locking cylinder is provided with a regular hexagonal structure.

[0012] Furthermore, prefabricated crossbars are inserted into the dovetail grooves between the prefabricated uprights, and dovetail blocks in the vertical direction are provided on both the left and right ends of the prefabricated crossbars.

[0013] Furthermore, a transparent protective plate is inserted into the strip groove between the assembled uprights, and the bottom end face of the transparent protective plate is provided with a through-groove groove on both the left and right sides.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The leveling support column is installed at the bottom of the prefabricated upright via threads for leveling operations. The regular triangular prism of the leveling support column prevents it from being rotated by unauthorized personnel. This solves the problem that the leveling structure at the bottom of the frame is easily rotated by unauthorized personnel, which can lead to the frame being misaligned under stress. It is also not convenient to make the leveling structure a structure that can only be rotated with special tools to prevent it from being easily rotated.

[0016] The prefabricated uprights and crossbars are assembled using a dovetail structure, and the assembled crossbars are easily locked in place by a locking sleeve to prevent them from coming loose. This solves the problem that the frame uprights and crossbars used to be fixed with multiple bolts, which affected the efficiency of disassembly and assembly, and that it was inconvenient to set up an assembly structure on the frame to allow for quick assembly and disassembly of the frame uprights and crossbars.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a prefabricated cleanroom, including a cleanroom wall 1; prefabricated uprights 2 are provided on both the left and right sides of the cleanroom wall 1 in a vertical direction to facilitate the support of various components. The bottom outer circumference of the prefabricated uprights 2 is threaded to facilitate the installation of locking cylinders 6 via threads. Four downward-through dovetail grooves are arranged in a ring array on the bottom outer circumference of the prefabricated uprights 2 to facilitate the insertion and assembly of prefabricated crossbars 5. A leveling screw hole is provided at the center of the bottom end face of the prefabricated uprights 2 to facilitate the installation of leveling support columns 3 via threads. Four upward-through strip grooves are arranged in a ring array on the outer circumference of the prefabricated uprights 2 to facilitate the placement and positioning of transparent enclosure panels 4. A fixing screw hole is provided at the center of the top end face of the prefabricated uprights 2 to facilitate the installation of locking columns 8 via threads. The fixed screw holes of the upright pole 2 are arranged in a ring with four blind insertion holes to facilitate the insertion and limiting of the stabilizing rod 7. The leveling screw holes of the assembled upright pole 2 are equipped with leveling support columns 3 in the vertical direction to facilitate the leveling operation of the cleanroom wall 1. The bottom of the leveling support column 3 is equipped with a ground contact circular plate to facilitate ground contact and support. The top end face of the ground contact circular plate of the leveling support column 3 is equipped with a regular triangular prism to facilitate rotation by a special tool matching the regular triangular prism. The top end face of the regular triangular prism of the leveling support column 3 is equipped with a threaded rod to facilitate threaded installation. The strip grooves between the assembled upright poles 2 are inserted with transparent enclosure plates 4 to facilitate the formation of a barrier. The bottom end face of the transparent enclosure plate 4 has through-holes on both the left and right sides to facilitate the fitting with the groove-free part of the assembled upright pole 2.

[0027] Among them, prefabricated crossbars 5 are inserted into the dovetail grooves between the prefabricated uprights 2, facilitating quick assembly and disassembly of the prefabricated crossbars 5. The left and right ends of the prefabricated crossbars 5 are provided with dovetail blocks in the vertical direction for easy assembly with the prefabricated uprights 2. An assembly locking cylinder 6 is threaded onto the outer circumference of the bottom of the prefabricated uprights 2, facilitating the locking and securing of the assembled prefabricated crossbars 5. The inner circumference of the assembly locking cylinder 6 is threaded for easy threaded installation. The outer circumference of the assembly locking cylinder 6 has a regular hexagonal structure for easy rotation and disassembly using tools. A sealing stabilizing rod 7 is inserted into the blind hole between the prefabricated uprights 2, facilitating the closure of the transparent enclosure panel 4. The bottom end face of the sealing stabilizing rod 7... Insertion posts are provided at both ends to facilitate insertion of the prefabricated upright 2 for positioning. Trapezoidal heads are provided on both ends of the closed stabilizing rod 7 to prevent obstruction of the closed locking post 8. An arc-shaped fitting groove is provided on the top end face of the trapezoidal head of the closed stabilizing rod 7 to facilitate the positioning ring plate of the closed locking post 8 to be inside. The closed locking post 8 is installed inside the fixing screw hole of the prefabricated upright 2 to facilitate the pressing and fixing of the closed stabilizing rod 7. A threaded rod is provided at the bottom of the closed locking post 8 for easy installation by thread. A positioning ring plate is provided on the outer circumference of the top of the threaded rod of the closed locking post 8 to facilitate pressing and preventing the closed stabilizing rod 7 from falling off. A regular hexagonal prism is provided on the top end face of the threaded rod of the closed locking post 8 to facilitate the rotation and disassembly of the closed locking post 8 by tools.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In this invention, when the leveling support column 3 is leveled, a special triangular prism tool is used to rotate the leveling support column 3 and engage it with the prefabricated upright 2. This allows the leveling support column 3 to rise and fall within the leveling screw hole at the bottom of the prefabricated upright 2 through thread engagement. Simultaneously, it is observed whether the cleanroom wall 1 is parallel to the external X-ray level, thus determining whether the cleanroom wall 1 is level. The triangular prism of the leveling support column 3 prevents unauthorized rotation, ensuring the frame's horizontal stability and solving the problem of the bottom leveling structure being easily rotated by unauthorized personnel, leading to frame skew. When assembling the various components of the cleanroom wall 1, the dovetail block of the prefabricated crossbar 5 is inserted along the dovetail groove of the prefabricated upright 2. The assembly locking cylinder 6 is then rotated using a tool to engage with the outer circumferential thread at the bottom of the prefabricated upright 2, causing the assembly locking cylinder 6 to rise and press against the bottom end face of the prefabricated crossbar 5. This ensures the assembly... The locking cylinder 6 locks the assembled crossbar 5, solving the problem that multiple bolts are needed to fix the frame uprights and crossbars, affecting the efficiency of disassembly and assembly. The leveling support column 3 is installed in the leveling screw hole of the assembled upright 2 through threads. The transparent enclosure plate 4 is inserted into the slot of the assembled upright 2 from above, so that the matching groove at the bottom of the transparent enclosure plate 4 locks the slotless part of the assembled upright 2. The insertion post of the closing stabilizing rod 7 is inserted into the insertion blind hole of the assembled upright 2. The closing locking post 8 is installed in the fixing screw hole of the assembled upright 2 through threads, so that the closing locking post 8 descends through thread engagement, and the limiting ring plate of the closing locking post 8 is pressed into the arc-shaped matching groove of the closing stabilizing rod 7, thereby forming an upper constraint on the transparent enclosure plate 4. At this time, all components of the cleanroom wall 1 are assembled. Note that multiple cleanroom wall 1s can be combined to form a complete assembled cleanroom, and the combination method is the same as described above.

[0030] Example 2: Unlike Example 1, the regular hexagonal prism of the locking pin 8 can also be set as a regular heptagonal prism, so that the locking pin 8 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the locking pin 8.

[0031] Example 3: The difference from Example 1 is that the regular hexagonal structure of the assembly locking cylinder 6 can also be set as a regular heptagonal structure. This makes it necessary to use a special tool that cooperates with the regular heptagonal structure to rotate the assembly locking cylinder 6, thus preventing non-workers from rotating and disassembling the assembly locking cylinder 6.
