Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a detachable door for clean rooms. Background Technology

[0002] Currently, cleanroom technology effectively controls pollutants such as particulates, harmful airborne particles, and bacteria according to customer requirements, and is widely used in industries such as semiconductors, optoelectronics, biomedicine, fine chemicals, and food processing. During the use of cleanrooms, doors need to be installed between adjacent cleanrooms to facilitate the passage of personnel or goods.

[0003] In some technical solutions, a square notch is cut into the cleanroom panel, and a door frame is installed at the notch. The door frame is welded and fixed by two horizontal frames and two vertical frames to increase the structural strength of the door. In this technical solution, the lower horizontal frame of the door is generally higher than the ground to facilitate the separation of the floors of adjacent cleanrooms; and there is no need to set a recessed groove in the ground, which reduces the difficulty of door installation.

[0004] However, in the above technical solution, when it is necessary to temporarily pass between adjacent clean rooms to facilitate the transfer of goods, the lower horizontal frame above the ground will actually obstruct the passage of vehicles and easily cause traffic jams.

[0005] Additionally, the lower horizontal frame of the door frame tends to accumulate dust and grime, making it relatively difficult to clean and requiring regular maintenance and cleaning. Utility Model Content

[0006] This invention provides a detachable door for cleanrooms, which can solve at least one of the above-mentioned technical problems.

[0007] To address the aforementioned technical problems, one or more embodiments of this utility model provide a detachable door for cleanrooms, comprising an upper horizontal frame, a lower horizontal frame, and two vertical frames forming a door frame. The left and right ends of the upper horizontal frame and the top of each vertical frame are respectively provided with 45-degree beveled surfaces. The left and right end faces of the upper horizontal frame are respectively connected to and welded to the top ends of the two vertical frames via the beveled surfaces. The lower horizontal frame fills the space between the bottom ends of the two vertical frames, with the bottom ends of the vertical frames and the lower horizontal frame flush. The left and right end faces of the lower horizontal frame abut against the sides of the two vertical frames.

[0008] The lower horizontal frame has square notches at both ends, which vertically penetrate the upper sidewall of the frame. An embedded part is pre-installed below the notch, supporting the upper sidewall of the lower horizontal frame. The embedded part has a first hole that penetrates vertically through itself. The side of the vertical frame near the lower horizontal frame forms a vertical sidewall with a horizontal through groove. A connector is installed within the through groove. The connector includes a flat plate and a stop portion that are fixed to each other. The flat plate extends through the through groove into the vertical frame and fits against the embedded part. The flat plate is embedded in the notch. The stop portion cannot extend through the through groove into the vertical frame. The flat plate has a second hole, and the same threaded component passes through both the first and second holes to fix the embedded part and connector.

[0009] The beneficial effects of one or more of the above technical solutions are as follows:

[0010] In this design, the door frame includes an upper horizontal frame, a lower horizontal frame, and two vertical frames. The upper ends of the two vertical frames are joined to the upper horizontal frame at a 45-degree bevel and welded in place, thereby increasing the overall structural strength of the door. While welding is used to enhance the structural strength of the door, the lower end face of the lower horizontal frame is flush with the lower end face of the vertical frames. The lower horizontal frame is secured using threaded connections via notches at both ends and pre-embedded parts extending into the vertical frames.

[0011] In this method, the lower horizontal frame and the lower end of the vertical frame can be quickly and detachably fixed by tightening the bolts. Furthermore, the flat plate attached to the embedded part can cover the gaps between the two ends of the lower horizontal frame and the sides of the vertical frame. In summary, this solution facilitates the quick assembly and disassembly of the entire lower horizontal frame to avoid obstructing vehicle passage; and it also facilitates the use of connectors to block the vertical gap between the lower horizontal frame and the vertical frame, reducing the probability of dirt accumulation.

Detailed Implementation

[0018] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0019] like Figures 1-5 As shown, one or more embodiments of this utility model provide a detachable door for cleanrooms, including an upper horizontal frame 1, a lower horizontal frame 3, and two vertical frames 2 forming a door frame. The left and right ends of the upper horizontal frame 1 and the top of the vertical frames 2 are respectively provided with 45-degree beveled surfaces. The left and right end faces of the upper horizontal frame 1 are respectively connected to and welded to the upper ends of the two vertical frames 2 through the beveled surfaces. The lower horizontal frame 3 fills the space between the lower ends of the two vertical frames 2, and the lower end faces of the vertical frames 2 and the lower horizontal frame 3 are flush. The left and right end faces of the lower horizontal frame 3 abut against the sides of the two vertical frames 2.

[0020] The lower horizontal frame 3 has square notches 7 at its left and right ends, which vertically penetrate the upper sidewall of the lower horizontal frame 3. An embedded part 6 is pre-embedded and fixed below the notch 7, supporting the upper sidewall of the lower horizontal frame 3. The embedded part 6 has a first hole 601 that penetrates vertically through itself. The side of the vertical frame 2 near the lower horizontal frame 3 is a vertical sidewall with a horizontal through groove 201. A connector 5 is provided within the through groove 201. The connector 5 includes a flat plate portion 502 and a stop portion that are fixed to each other. The flat plate portion 502 extends out of the vertical frame 2 along the through groove 201 and fits against the embedded part 6. The flat plate portion 502 is embedded in the notch 7; the stop portion 501 cannot extend out of the vertical frame 2 along the through groove 201. The flat plate portion 502 has a second hole 503. The same threaded part is threaded through both the first hole 601 and the second hole 503 to fix the embedded part 6 and the connector 5.

[0021] Specifically, the lower horizontal frame 3 is embedded between the lower ends of the two vertical frames 2. At this time, the left and right end faces of the lower horizontal frame 3 abut against the side of the vertical frame 2 near the center of the door, thus easily forming a vertical gap between the end face of the lower horizontal frame 3 and the side of the vertical frame 2. After long-term use, dirt and dust can easily accumulate inside the gap under the action of gravity, thereby affecting the cleanliness of the entire cleanroom. In this embodiment, a flat plate with a connector extends from the through groove of the vertical side wall of the vertical frame. The flat plate 502 can cover the above-mentioned vertical gap while fixing the embedded part 6, reducing the probability of dirt accumulating in the gap under gravity. Since the through groove 201 is opened in the horizontal direction and the flat plate extends in the horizontal direction, the probability of dust accumulating in the gap between the through groove 201 and the flat plate 502 under the action of gravity is small, and dirt is not easily accumulated.

[0022] Specifically, the upper and lower horizontal frames are installed in different positions on the door, and their structures are not the same.

[0023] In this embodiment, the upper horizontal frame 1, the lower horizontal frame 3 and the vertical frame 2 each have a mounting surface facing the center of the door. One end of the mounting surface along the thickness direction of the door is provided with a protrusion 8, which protrudes from the mounting surface to the center of the door.

[0024] Specifically, the upper horizontal frame 1, the lower horizontal frame 3, and the vertical frame 2 enclose a passageway space 4, which is used for pedestrian passage. Vehicles can also pass through after the lower horizontal frame 3 is removed.

[0025] In this embodiment, the outer contour of the door frame has a mounting groove 101 surrounding the center of the door, and the cross-section of the mounting groove 101 is square.

[0026] Specifically, the outer edges of the upper horizontal frame 1, the lower horizontal frame 3, and the vertical frame 2 each have a portion of the structure of the mounting groove 101. The various parts of the mounting groove 101 are interconnected and combined to form a circumferentially arranged groove structure. Furthermore, the structural design of the mounting groove 101 facilitates the insertion of the notch in the cleanroom panel into the interior of the mounting groove 101, thereby facilitating the fixing of the door and the cleanroom panel.

[0027] In this embodiment, the upper horizontal frame 1, the lower horizontal frame 3, and the vertical frame 2 are all integral profile structures formed by bending multiple plate segments.

[0028] Specifically, the door body here is made entirely of steel. In other embodiments, the horizontal and vertical frames can also be made of alloy or other metal materials.

[0029] In this embodiment, the pre-embedded part 6 has a first hole 601 and a third hole 602 at both ends along the length direction, and the third hole 602 is used to connect the lower horizontal frame 3.

[0030] Specifically, the embedded part 6 has two first holes 601 and two third holes 602 at both ends along its own length direction (that is, along the left and right direction of the lower horizontal frame).

[0031] In this embodiment, the embedded part 6 is a pre-embedded square plate.

[0032] Specifically, the embedded part 6 here is a metal plate, which can be fixed to the cleanroom floor by welding or bolting. When using bolting, the embedded part 6 is fixed to the pre-installed mounting column or mounting plate on the ground through the third hole 602 and the bolt. After the embedded part is installed in place, the lower horizontal frame between the two vertical frames is lowered from above, so that the bottom surface of the upper side wall of the lower horizontal frame overlaps the embedded part.

[0033] In this embodiment, the stop member is an L-shaped plate, and both the flat plate portion 502 and the stop portion 501 are square plates, and the two are perpendicular to each other.

[0034] Specifically, the shape and size of the flat plate 502 are the same as the shape and size of the aforementioned notch.

[0035] In this embodiment, the through groove 201 is a horizontally arranged square groove. The thickness of the through groove is the same as the thickness of the flat plate, and the width of the through groove is also the same as the width of the flat plate.

[0036] It should be noted that in this embodiment, the door panel can be installed in the passageway 4 of the door frame via hinges, or the door panel can be left uninstalled in the passageway 4, which can be determined by those skilled in the art.

[0037] Working principle: When using this device, firstly, an installation opening for the door body is opened in the cleanroom. Then, corresponding embedded parts 6 are pre-embedded and fixed in the ground below the installation opening.

[0038] Install the upper horizontal frame 1 and the two vertical frames 2 into place, and insert the aluminum profiles for connecting the cleanroom panel into the mounting grooves of the upper horizontal frame 1 and the vertical frames 2. Then, fix the upper horizontal frame 1 and the vertical frames 2 by welding.

[0039] Then, insert the lower horizontal frame between the two vertical frames 2 along the direction of travel, and press it down until the upper side wall of the lower horizontal frame overlaps the embedded part 6. At this time, the flat plate part 502 of the connector 5 in the vertical frame 2 is embedded in the notches 7 at both ends of the lower horizontal frame. The second hole of the flat plate part 502 and the first hole of the embedded part 6 are aligned, and then the connector 5 and the embedded part 6 are locked together with bolts.

[0040] When it is necessary to remove the lower horizontal frame, remove the bolts between the connector 5 and the embedded part 6, and pull the lower horizontal frame upward until it moves and rises above the embedded part 6 and the connector 5. Remove the lower horizontal frame from between the two vertical frames 2 along the passage direction of the door.

[0041] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0042] Any aspects of this utility model not described in detail are known to those skilled in the art.
