Description

Technical Field

[0001] The present invention relates to the technical field of raised floors used in clean rooms, and particularly to a raised floor for clean rooms. Background Art

[0002] The raised floor is assembled by combining adjustable supports, beams, panels, etc. Its main function is to prevent static electricity in the field of electronic appliances. In addition to this field, the raised floor also has a relatively wide application in the technical field of clean rooms. The main use of the raised floor in the clean room is to form an air flow indoors, vertically introduce the air processed by the high-efficiency filter at the top of the clean room into the return air duct under the floor, so as to form a vertical air flow pattern in the clean room. In addition, the raised floor in the clean room can also play a moisture-proof effect.

[0003] During the use of the clean room, it is necessary to regularly clean the interior. Vacuum cleaning can be carried out either by using a centralized vacuum pipeline system or by using a portable automatic vacuum cleaner. Wet cleaning is the most widely used method, but dry cleaning is prohibited in the clean room because the particles falling off from the cleaning tool (rag) during cleaning will fly everywhere and be blown by the air flow and become statically charged. However, the existing raised floors are all fixed to the ground through legs, and then the floor is installed on the top of the legs. When cleaning is required, the floor needs to be removed from the legs, and then the area under the floor is cleaned. However, since the legs are fixed to the ground, there will be many sanitary dead corners during cleaning, resulting in greater cleaning difficulty. In addition, if the clean room needs to be temporarily used for other purposes, the entire bottom of the legs needs to be disassembled, which involves a large amount of work and is not convenient for restoring the use of the raised floor. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art that the cleaning of the area under the raised floor in the clean room is difficult and the amount of work is large during restoration, and to provide a raised floor for clean rooms.

Detailed implementation manners

[0027] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0028] See Figures 1 to 10, an embodiment of the present invention discloses an elevated floor for a clean room, mainly including a receiving groove 3 below the ground, in which the support legs 2 are folded and stored, realizing flexible adjustment and convenient cleaning of the elevated floor. The receiving groove 3 is a rectangular groove with an open top and has a certain depth. The receiving groove 3 serves as the storage space for the support legs 2, and its design needs to fully consider the folding and unfolding requirements of the support legs 2. Multiple mounting holes are provided at the bottom of the receiving groove 3 for firmly mounting the receiving groove 3 below the ground. At the same time, a lining block 301 is horizontally arranged inside the receiving groove 3 to enhance the structural strength of the groove body. At the same time, the lining block 301 has a certain height. When the receiving groove 3 is fixed, there will be a protruding part of about two centimeters for the expansion bolt. The top of the lining block 301 is higher than the expansion bolt, and when the support legs 2 are laid down, they will be placed on the lining plate, leaving a space at the bottom to improve the storage effect. An end cover 4 is movably arranged on the side of the receiving groove 3, which is convenient for closing the groove opening when the support legs 2 are unfolded, maintaining the cleanliness of the internal environment of the clean room. And the end cover 4 can be designed in two forms according to needs. One is a movable split design. The end cover 4 is divided into two parts. One part is that after the support legs 2 are erected, the end cover 4 covers the open part of the receiving groove 3 on the right to keep the inside of the receiving groove 3 sealed. And after the end cover 4 is sealed, the left part abuts against the lower part of the support legs 2, assisting in maintaining the stability of the support legs 2 to a certain extent. An end cover 4 is hinged on the left side wall of the receiving groove 3. When the support legs 2 are erected, the left end cover 4 is lifted. When the support legs 2 are put down, the left end cover 4 will cover the exposed space and cover the opening of the receiving groove 3 to realize the complete storage of the support legs 2 and ensure the use effect. The other is that both parts of the end cover 4 are hinged on the side wall of the receiving groove 3, and a sealing strip is provided on the side of the section height to improve the sealing effect.

[0029] A sliding groove 302 is provided on the inner wall of the receiving groove 3. The sliding groove 302 is arranged along the moving direction of the support legs 2 to provide guidance for the folding and unfolding of the support legs 2. The sliding groove 302 is vertically arranged, and the top of the sliding groove 302 is circular to facilitate the smooth transition of the support legs 2 during folding and unfolding. A sliding shaft 303 is provided at the lower part of the support legs 2. The end of the sliding shaft 303 is slidably arranged inside the sliding groove 302 to ensure the stability of the support legs 2 during movement. The sliding shaft 303 is fixedly arranged with the support legs 2, and its end is designed as a square to match the shape of the sliding groove 302. When in use, when the state of the support legs 2 needs to be changed, the support legs 2 are moved upward as a whole so that the sliding shaft 303 moves to the top of the sliding groove 302, rotated 90 degrees, and then the support legs 2 are slid down. The sliding shaft 303 will still be inside the sliding groove 302, ensuring the state stability of the support legs 2 and not affecting the change of the state of the support legs 2, and ensuring the use effect.

[0030] When the support leg 2 needs to be deployed, first pull it upward from inside the receiving groove 3, then rotate the head 90 degrees, and then the support leg 2 moves downward. To ensure the stability of the support leg 2 in the deployed state, a locking device for stabilizing the support leg 2 is provided inside the receiving groove 3. In this embodiment, the cross-section of the support leg 2 is a cube. The locking device includes a positioning groove 304 provided at the bottom of the receiving groove 3. The bottom of the support leg 2 can be snapped into the inside of the positioning groove 304. On the inner side of the upper edge of the positioning groove 304, there is a locking block 305. At the bottom of the locking block 305, there is a rotating shaft. The rotating shaft is arranged inside the positioning groove 304, so that the locking block 305 can rotate on the top of the positioning groove 304. A torsion spring is arranged on the rotating shaft to provide a pre-tightening force for the locking block 305. The cross-section of the locking block 305 is triangular. When the support leg 2 is retracted, under the action of the torsion spring, the inclined surface of the locking block 305 faces upward, so that one side of the locking block 305 is inside the positioning groove 304. During use, the support leg 2 moves vertically downward. The bottom of the support leg 2 first contacts the inclined surface of the locking block 305. Under the action of the pressure, the locking block 305 deflects inward, so that the locking block 305 gradually clamps between the positioning groove 304 and the support leg 2, filling the gap therebetween. Since the height of the positioning groove 304 is only about 2 cm, due to the low height, the stability is poor. Compared with directly using the positioning groove 304 for locking, the stability of the support leg 2 is greatly improved. A threaded hole 306 is provided at the bottom of the positioning groove 304 for connecting the stabilizing rod 502 to further fix the position of the support leg 2 and provide a downward pressure for the support leg 2. The stabilizing rod 502 is vertically arranged at the middle position of the support leg 2. The stabilizing rod 502 is screwed to the middle position of the support leg 2, and the thread pitch at the threaded connection between the stabilizing rod 502 and the support leg 2 is greater than the thread pitch inside the threaded hole 306, so that when the stabilizing rod 502 rotates, the support leg 2 can move downward and enter the inside of the positioning groove 304. After the support leg 2 reaches the bottom of the positioning groove 304, the stabilizing rod 502 cannot rotate, so that the support rod remains vertically stable. Combined with the locking of the locking block 305 on the side, the support stability of the support leg 2 is ensured, so that the floor body 1 can work stably. After the support leg 2 is vertically stable, cover the upper end cover 4 on the right side to close the opening surface of the receiving groove 3, ensure the cleanliness inside, reduce the cleaning dead angle, and greatly reduce the cleaning difficulty compared with the existing method of exposing the fixed bolts on the bottom surface.

[0031] A support base 5 for installing the floor body 1 is provided at the top of the support leg 2. Positioning holes 501 penetrate through the four corners of the support base 5. Long strip holes are provided directly below the positioning holes 501 to facilitate the insertion of the connecting columns 101 on the floor body 1. The support base 5 is such that an adjusting rod 6 is connected to the support leg 2 at the bottom of the support base 5. The bottom of the adjusting rod 6 is provided with threads to connect with the adjusting hole at the middle position of the support leg 2. A through hole is provided at the middle position of the adjusting rod 6 for the stabilizing rod 502 to pass through. Threads are provided in the inner part of the adjusting hole to connect with the stabilizing rod 502. The through hole is set in a stepped shape with a larger diameter at the upper part to facilitate the lifting adjustment of the adjusting rod 6. A locking bolt is provided at the top of the adjusting rod 6 on the support leg 2 to fix the height of the adjusting rod 6, facilitating the height adjustment between multiple support legs 2 and adjusting the support height of each floor body 1 to the same horizontal plane, coarsely adjusting the height, and ensuring the levelness of the floor body 1 on the premise of ensuring stability, thereby improving the use effect.

[0032] A clamping device for connecting the floor body 1 is provided on the side of the adjusting rod 6 to facilitate the installation and disassembly of the floor body 1. The clamping device is provided at the upper part of the stabilizing rod 502 and includes a lifting tube 7, a sleeve 701, and a clamping column 702. The lifting tube 7 is sleeved on the upper part of the stabilizing rod 502. A spring is provided at the bottom of the through hole of the adjusting rod 6 to push the lifting tube 7 upward. A screw head 503 is provided at the upper part of the lifting tube 7, and the screw head 503 is screwed with the inner wall of the adjusting rod 6. The up and down adjustment of the lifting tube 7 is achieved by rotating the screw head 503 downward. Four long strip holes are provided on the side wall of the adjusting rod 6 in the vertical direction. Four clamping columns 702 are provided on the side wall of the lifting tube 7. The ends of the clamping columns 702 extend out of the long strip holes to connect with the floor body 1. A sleeve 701 is provided on the side wall of the lifting tube 7. A top spring is provided inside the sleeve 701. The clamping column 702 is movably arranged inside the sleeve 701, enabling the clamping column 702 to move up and down driven by the lifting tube 7.

[0033] The floor body 1, as the top component of the raised floor, needs to be designed by fully considering factors such as anti-static, moisture-proof, and installation convenience. A connecting column 101 that cooperates with the clamping column 702 is provided at the lower part of the floor body 1 to facilitate connection with the support base 5. At the same time, the material and surface treatment of the floor body 1 need to meet the usage requirements of the cleanroom to ensure that it will not pollute the internal environment of the cleanroom. To ensure that the installation of the floor body 1 has sufficient structural strength, a slot is also provided between the two positioning holes 501 for connecting the reinforcing bar. The reinforcing bar is clamped inside the slot, and the side of the floor body 1 is pressed on the reinforcing bar to ensure safety in use. Connecting columns 101 are screwed at the corners of the floor body 1, and a wedge-shaped notch 102 is provided on the side wall of the connecting column 101. When the floor body 1 needs to be installed, first insert the connecting column 101 at the bottom of it into the positioning hole 501 at the upper part of the support base 5. Then, rotate the screw head 503 at the upper part of the lifting tube 7 to drive the clamping column 702 to move downward until the end of the clamping column 702 is connected to the wedge-shaped notch 102 on the floor body 1. At this time, the floor body 1 is firmly installed on the support base 5 under the downward pressure of the clamping column 702, ensuring the stability of the connection and improving the usage effect.

[0034] When the floor body 1 needs to be disassembled, first remove the screw head 503, and the clamping column 702 moves upward, so that the end of the clamping column 702 moves upward from the wedge-shaped notch 102. Then, turn the connecting column 101 by 180 degrees so that the back side of the wedge-shaped notch 102 faces the clamping column 702. Then, the connecting column 101 can be pulled out upward to separate the floor body 1 from the support base 5. Then, turn the stabilizing rod 502 upward so that the stabilizing rod 502 disengages from the positioning groove 304. Then, pull out the support leg 2 from the positioning groove 304. If it is stuck too tightly, a hammer needs to be used to tap upward. After the support leg 2 is removed, the locking block 305 resets with the inclined surface facing upward for easy locking next time. The support leg 2 moves upward, opening the cover plate. The sliding shaft 303 rotates 90 degrees on the top of the sliding groove 302 and then lies flat on the lining block 301 inside the receiving groove 3. There is no contact between the support leg 2 and the locking block 305. Then, cover the end cap 4. In this way, the step of disassembling the bottom of the support leg 2 is omitted, and the ground is still kept flat. When cleaning, the retracted support leg 2 maintains a flat surface, and wet cleaning can be used for a large range of cleaning, greatly improving the cleaning efficiency. At the same time, when converting applications in the workshop, except for the pipelines at the bottom, the disassembly of the support leg 2 is omitted, improving the construction efficiency. There is no need to disassemble the entire raised floor system, greatly reducing the project quantity and the difficulty of restoration.
