[0002] Clean room (also known as cleanroom) technology is widely used in biology, electronics, medicine, semiconductors, precision manufacturing and other industries to provide a controlled clean environment for production, scientific research and other activities. At the same time, the maintenance wall panels for clean rooms are generally color-coated steel plates with a thickness of 50mm or 100mm. In the relevant technology, during the construction of the clean room, crossbeams and longitudinal beams are required to act as a skeleton to provide sufficient support strength for the color-coated steel plate wall. However, when the existing color-coated steel plates are connected with crossbeams and longitudinal beams, bolts are mostly used. It takes multiple bolts to fix a color-coated steel plate. There are tens of thousands of bolts used to build a clean room. This makes the installation of the color-coated steel plate wall extremely time-consuming and inefficient, and the bolts need to be removed during disassembly, which is very inconvenient.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Existing color steel plates are mostly connected with cross beams and longitudinal beams by bolts, which makes the installation of color steel plate walls extremely time-consuming and inefficient. In addition, the bolts need to be removed during disassembly, which is very inconvenient.

[0023] Example 1: A color steel plate wall for a clean room, please refer to Figure 1-Figure 5 , including a crossbeam 1, a plurality of evenly distributed (two in the figure) longitudinal beams 2 are fixedly connected to the upper side of the crossbeam 1, a color steel plate 3 is arranged between two adjacent longitudinal beams 2, the color steel plate 3 is provided with a plurality of evenly distributed (four in the figure) through holes, the longitudinal beam 2 is provided with a plurality of cavities 201 that are symmetrical and evenly distributed up and down (four in the figure), a sliding plate 4 is slidably connected in the cavity 201, the sliding plate 4 divides the adjacent cavity 201 into two parts, a connecting column 5 is fixedly connected to the front side of the sliding plate 4, the connecting column 5 penetrates the front side of the adjacent longitudinal beam 2, a sliding shell 6 is fixedly connected to the front side of the connecting column 5, and the sliding shell 6 and the color steel plate 3 The adjacent through holes on the color steel plate 3 are slidably matched, and the sliding shell 6 penetrates into the adjacent through holes on the color steel plate 3, so as to position the installation of the color steel plate 3 to improve the installation quality of the color steel plate 3. The sliding shell 6 is slidably connected with a plurality of (three are shown in the figure) circumferentially evenly distributed limit pins 7, and the limit pins 7 are squeezed and matched with the color steel plate 3. When the color steel plate 3 contacts the adjacent longitudinal beam 2, the limit pins 7 clamp the color steel plate 3, thereby completing the preliminary fixation of the color steel plate 3. A tension spring is arranged between the limit pin 7 and the adjacent sliding shell 6. The tension spring is initially in a stretched state and is used to move the adjacent limit pin 7 toward the direction close to the axis of the adjacent sliding shell 6.

[0024] See also Figure 4 and Figure 5 The sliding shell 6 is slidably connected with a transmission rod 8 that passes through its front side, and a sliding cone 9 is fixed to the rear side of the transmission rod 8. The top end of the sliding cone 9 faces backward, and the sliding cone 9 is located in the adjacent sliding shell 6. The three adjacent limit pins 7 are all squeezed and matched with the adjacent sliding cones 9. When the sliding cone 9 moves forward, the three adjacent limit pins 7 lose the squeezing of the adjacent sliding cones 9. The limit pins 7 move toward the direction close to the axis of the adjacent sliding shell 6 under the action of the adjacent tension spring. When the sliding cone 9 moves backward, the sliding cone 9 squeezes the three adjacent limit pins 7. The limiting pin 7 moves the limiting pin 7 away from the axis of the adjacent sliding shell 6 and stretches the adjacent tension spring. A spring is arranged between the sliding cone 9 and the adjacent sliding shell 6. The spring is always in a compressed state and is used to move the sliding cone 9 backward. The elastic force of the spring adjacent to the sliding cone 9 is greater than the sum of the tension forces of the springs adjacent to the limiting pin 7 uniformly distributed circumferentially, so that the sliding cone 9 can move backward under the action of the adjacent springs and squeeze the three adjacent limiting pins 7, so that the three limiting pins 7 overcome the resistance of the adjacent tension springs and move respectively.

[0025] See also Figure 4 and Figure 5The upper side of the sliding shell 6 is slidably connected to the limit rod 10, and a spring is arranged between the limit rod 10 and the adjacent sliding shell 6. The spring is initially in a stored force state, and is used to move the adjacent limit rod 10 downward. The transmission rod 8 is provided with a limit groove that cooperates with the adjacent limit rod 10. When the limit rod 10 is inserted into the limit groove of the adjacent transmission rod 8, the transmission rod 8 cannot move. The distance between the upper limit groove of the transmission rod 8 and the adjacent limit rod 10 is greater than the height of the sliding cone 9, so that when the adjacent three limit pins 7 squeeze the adjacent sliding cone 9 to drive the adjacent transmission rod 8 to move forward, the limit rod 10 will not limit the adjacent transmission rod 8. When the transmission rod 8 is pulled forward to move until its upper limit groove is aligned with the adjacent limit rod 10, the limit rod 10 limits the adjacent transmission rod 8 again.

[0026] See also Figure 2 , Figure 6 and Figure 7 A connecting pipe 11 is provided on the rear side of the longitudinal beam 2, and a ball valve 12 is installed in the connecting pipe 11. The ball valve 12 is used to control the opening and closing of the adjacent connecting pipes 11. The front sides of the four cavities 201 on the adjacent longitudinal beams 2 are connected with the adjacent connecting pipes 11 through pipelines, so that the liquid can enter the four adjacent cavities 201 through the connecting pipes 11, and the liquid in the cavity 201 can be discharged through the adjacent connecting pipes 11. The connecting pipe 11 is connected to the injection device, and the injection device is an existing device (such as a water pump, etc.), which will not be described in detail here.

[0027] When using the device, first install the crossbeam 1, lay several crossbeams 1 around the outline of the workshop to be built, then connect two adjacent crossbeams 1, and then connect several evenly distributed longitudinal beams 2 to the adjacent crossbeams 1 respectively. After the longitudinal beams 2 are installed, start to install the color steel plate 3, so that the four evenly distributed through holes on the color steel plate 3 are aligned with the adjacent sliding shells 6 on the two adjacent longitudinal beams 2 respectively, and then move the color steel plate 3 backward to make the sliding shell 6 penetrate the adjacent through holes on the color steel plate 3. In the process of the color steel plate 3 moving backward, the color steel plate 3 squeezes several adjacent limit pins 7. The limit pin 7 is squeezed and moves toward the direction close to the axis of the adjacent sliding shell 6 and restores the adjacent tension spring. The three evenly distributed limit pins 7 jointly squeeze the adjacent sliding cone 9, so that the sliding cone 9 drives the adjacent transmission rod 8 to move forward and compress the adjacent spring. When the color steel plate 3 contacts the two adjacent longitudinal beams 2 and stops moving, the color steel plate 3 no longer squeezes the limit pin 7. The sliding cone 9 moves backward under the action of the adjacent spring. The sliding cone 9 squeezes the three adjacent limit pins 7, so that the limit pin 7 is reset and the adjacent tension spring is stretched. At this time, the preliminary installation of a color steel plate 3 is completed.

[0028] After several limit pins 7 have fixed the color steel plate 3, the injection device is connected to the connecting pipe 11, and liquid (such as water or other liquids) is started to be injected into the connecting pipe 11. The liquid enters the adjacent connecting pipe 11 from the injection device, and then enters the four adjacent cavities 201 through the pipeline. The liquid in the cavity 201 increases, pushing the adjacent sliding plate 4 to move backward, and the sliding plate 4 drives the adjacent connecting column 5 to move. The connecting column 5 drives the three limit pins 7 to move backward through the adjacent sliding shell 6, thereby increasing the pressure of the limit pin 7 on the color steel plate 3 to prevent the color steel plate 3 from shaking. When the pressure of the limit pin 7 on the color steel plate 3 reaches the specified value, the ball valve 12 is turned 90° to close and the injection is stopped.

[0029] When disassembling the device, first turn the ball valve 12 90° to open it, release the liquid in the four adjacent cavities 201, and then pull the transmission rod 8 forward. The transmission rod 8 drives the adjacent sliding cone 9 to move forward and compress the adjacent spring. When the sliding cone 9 moves forward, the adjacent limit pin 7 moves in the direction close to the axis of the adjacent sliding shell 6 under the action of the adjacent tension spring, so that the limit pin 7 releases the obstruction of the color steel plate 3. When the sliding cone 9 is separated from the adjacent limit pin 7, the limit groove on the transmission rod 8 has not yet been aligned with the adjacent limit rod 10. At this time, continue to pull the transmission rod 8 forward. When the limit groove on the transmission rod 8 is aligned with the adjacent limit rod 10, the limit rod 10 moves downward under the action of the adjacent spring and is inserted into the limit groove of the adjacent transmission rod 8, and locks the transmission rod 8. After operating the four transmission rods 8 adjacent to the color steel plate 3 in this way, the color steel plate 3 can be moved forward to be removed, and then the longitudinal beam 2 is removed from the adjacent cross beam 1, and finally the cross beam 1 is removed to complete the disassembly.

[0030] When fixing the existing color steel plates, screws are used to fix the color steel plates. However, when the staff applies torque to the screws, they cannot accurately control the torque of the screws, which will cause different torques of the screws fixing different positions of the color steel plates, affecting the fixing effect of the color steel plates.

[0031] Example 2: Based on Example 1, please refer to Figure 6 and Figure 7, and further includes a plurality of (two shown in the figure) evenly distributed fixed shells 13, the two fixed shells 13 are respectively fixed to the rear sides of the adjacent longitudinal beams 2, a sliding rod 14 is slidably connected to the left side of the fixed shell 13, the sliding rod 14 is hinged with a telescopic rod 15 fixed to the adjacent ball valve 12, the translation of the sliding rod 14 is converted into the rotation of the adjacent ball valve 12 through the adjacent telescopic rod 15, the angle between the telescopic rod 15 and the adjacent sliding rod 14 is 135°, the maximum movement distance of the sliding rod 14 is twice the vertical distance between the rotation axis of the ball valve 12 and the axis of the adjacent sliding rod 14, so that the sliding rod 14 just drives the adjacent ball valve 12 to rotate 90° from the start to the end of the movement, so as to ensure that the ball valve 12 is completely closed, and the fixed shell 13 is connected to the rear side of the adjacent connecting pipe 11 through a pipeline.

[0032] See also Figure 7 and Figure 8 The fixed shell 13 is slidably connected with an adjustment plate 16 and a limit column 17. A spring is arranged between the limit column 17 and the adjacent adjustment plate 16. The spring is always in a compressed state, so that the adjacent limit column 17 provides resistance for the adjacent sliding rod 14. The sliding rod 14 is provided with a groove that cooperates with the adjacent limit column 17. When the limit column 17 is inserted into the groove of the adjacent sliding rod 14, the sliding rod 14 needs to overcome the resistance of the adjacent limit column 17 before it can move.

[0033] See also Figure 8 The fixed shell 13 is threadedly connected with a threaded rod 18, and the threaded rod 18 is rotatably connected to the adjacent adjusting plate 16. The position of the adjacent adjusting plate 16 is adjusted by rotating the threaded rod 18, thereby changing the initial compression amount of the spring adjacent to the adjusting plate 16 to change the resistance that the sliding rod 14 needs to overcome when moving.

[0034] When injecting liquid into the connecting tube 11, first rotate the threaded rod 18, and the threaded rod 18 drives the adjacent adjusting plate 16 to move, thereby adjusting the initial compression amount of the spring adjacent to the adjusting plate 16, and then adjusting the resistance of the adjacent limiting column 17 to the adjacent sliding rod 14, so as to change the pressure at the end of the injection, and the liquid enters the adjacent fixed shell 13 through the pipeline. When the liquid pressure in the four cavities 201 reaches the specified value, the limiting column 17 can no longer limit the adjacent sliding rod 14, and the sliding rod 14 squeezes the adjacent limiting column 17, so that the limiting column 17 moves upward and compresses the adjacent spring. After the column 17 is separated from the groove on the adjacent sliding rod 14, the limit column 17 is reset under the action of the adjacent spring, the resistance of the sliding rod 14 is instantly reduced, and it moves quickly to the left, the sliding rod 14 drives the adjacent telescopic rod 15 to rotate, and the telescopic rod 15 drives the adjacent ball valve 12 to rotate. When the sliding rod 14 moves to the maximum distance, the ball valve 12 rotates 90°, thereby closing the ball valve 12 and stopping the connecting pipe 11 from injecting liquid into the four cavities 201. At this time, the injection device is closed, thereby achieving accurate control of the pressure in the four cavities 201, thereby achieving accurate control of the fixing pressure of the color steel plate 3 by the limit pin 7.

[0035] When the device is disassembled, the sliding rod 14 is moved to the right, and the sliding rod 14 drives the adjacent ball valve 12 to rotate 90° and open through the adjacent telescopic rod 15, so as to discharge the liquid in the cavity 201. When the sliding rod 14 moves to contact the adjacent limit column 17, the sliding rod 14 squeezes the adjacent limit column 17 to move upward, and the limit column 17 compresses the adjacent spring. When the groove on the sliding rod 14 is aligned with the adjacent limit column 17, the limit column 17 moves downward under the action of the adjacent spring and is reinserted into the groove on the adjacent sliding rod 14, and the movement of the sliding rod 14 is stopped at this time.

[0036] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
