[0016] (III) Beneficial effects

[0017] The present invention provides a project progress display board for water conservancy project construction management and construction, which has the following beneficial effects:

[0018] (1) When the pressure rod of the present invention is used, it is rotatably connected with the rotating column, so that the pressure rod in the horizontal state is rotated to the vertical state, so that the two pressure rods press the two sides of the paper respectively. When the pressure rod is rotated to the vertical state, the L-shaped support block at the bottom can be firmly pressed against the inner bottom of the display slot through the movable groove, the movable block and the spring 2, so that the pressure rod is more stable when pressing the paper, and will not deviate to affect the viewing. In addition, the two pressure rods in the horizontal state will be supported by each other through the two L-shaped support blocks, so as to horizontally cover the top of the display slot for storage, which is convenient for putting in the paper.

[0019] (2) The present invention sets a pressure rod to rotate to a vertical state to press the paper. The wedge-shaped pressure groove and the wedge-shaped pressure block are set to push the pressure rod to move backward. When the pressure rod rotates to a vertical state, the stop block presses against the rear surface of the stop block, so that the upper part of the pressure rod presses the spring 1 backward, so that the pressure rod fits more closely to the inner rear surface of the display slot and can press the paper more tightly. In a normal state, the spring 1 pushes the pressure rod to move forward and press against the rear surface of the stop block. Therefore, when the wedge-shaped pressure block is not engaged in the wedge-shaped pressure groove, the gap between the pressure rod and the display slot is larger, which is convenient for inserting the paper and then pressing it tightly through the pressure rod.

[0020] (3) When the display board is completely stored in the display frame, the left side of the cover plate fits with the right side of the display frame, the plug-in block is plugged into the plug-in interface, and the locking block is locked in the locking opening, so that the display board is more stable in the display frame and will not fall out easily. When the locking block is squeezed, the wedge-shaped movable block can slide through the T-shaped slide bar and the sliding sleeve, so that the wedge-shaped groove can push the two wedge-shaped movable block compression springs to approach each other, so that the locking block will shrink into the cavity, and the shrinkage is difficult and more complete, which makes it convenient for the plug-in block to be plugged into the plug-in interface and increases the difficulty of pulling out the plug-in block, so that the cover plate is more stable in the display frame, and the anti-slip block prevents the locking block from falling out of the cavity.

When the device is in use, the device is prevented in the corresponding position by the bottom plate 1, and the support rod 2 is adjusted to a suitable height for easy viewing. The paper recording the progress of the project pasted inside the display frame 3 can be viewed through the glass observation window 4. When the paper is put in, the display board 6 is pulled out of the display frame 3 through the sealing plate 8, and then the paper recording the progress of the project is attached to the display groove 9, and the display board 6 is pressed by the pressing rod 12. The display board 6 slides in the slide groove 5 through the anti-slip rod 7, which can prevent the display board 6 from slipping out.

When the pressing rod 12 is rotated to the vertical state to press the paper, the provided wedge-shaped pressing groove 18 and the wedge-shaped pressing block 19 will push the pressing rod 12 to move backward, so that the paper can be pressed more tightly. The spring 13 will push the pressing rod 12 to move forward and press against the rear surface of the stopper 11 in the normal state, so that when the wedge-shaped pressing block 19 is not engaged in the wedge-shaped pressing groove 18, the gap between the pressing rod 12 and the display slot 9 is larger, which is convenient for putting in the paper.When the pressing rod 12 is pressed tightly, the two pressing rods 12 in the horizontal state will be pressed against each other by two L-shaped blocks 17, so as to horizontally cover the top of the display slot 9 for storage, making it convenient to put in the paper.

[0031] Furthermore, universal wheels 20 are fixedly connected to the four corners of the lower surface of the base plate 1, and the universal wheels 20 have brakes to facilitate the movement and fixed-point placement of the entire device.

[0032] Furthermore, the support rod 2 is a retractable hydraulic retractable rod, and the display height of the device can be changed as needed.

[0033] Furthermore, the right side of the display frame 3 is located in front of and behind the display board 6 and is fixedly connected with a plurality of plug-in blocks 21, and the upper and lower surfaces of the plug-in blocks 21 are provided with snap-fitting openings 22. The left side of the cover plate 8 is located in front of and behind the display board 6 and is provided with plug-in ports 23. The interior of the cover plate 8 is located above and below the plug-in ports 23 and is provided with cavities 24. The inner sides of two adjacent cavities 24 are fixedly connected with T-shaped slide bars 25 on opposite sides, and the outer sides of the T-shaped slide bars 25 are slidably connected with two sliding sleeves 26. The sliding sleeves A wedge-shaped movable block 27 is fixedly connected to the side away from the T-shaped slide 25. A spring 28 is fixedly connected between the opposite sides of the two wedge-shaped movable blocks 27 in the same cavity 24. A snap-fit ​​block 29 is slidably connected inside the cavity 24. A wedge-shaped groove 30 is provided on the side away from the plug-in port 23 of the snap-fit ​​block 29. The wedge-shaped groove 30 is located on the outer sides of the two wedge-shaped movable blocks 27 in the same cavity 24, and the inner side walls are respectively in contact with the opposite sides of the two wedge-shaped movable blocks 27. The snap-fit ​​block 29 is away from the T-shaped slide 25. One end of the slide bar 25 passes through the cavity 24 and extends to the inner side of the plug-in port 23. The outer wall of the snap-in block 29 is fixedly connected with the anti-drop-out block 31. The outer wall of the anti-drop-out block 31 fits with the inner wall of the cavity 24. When the display board 6 is completely stored in the display frame 3, the left side of the sealing plate 8 fits with the right side of the display frame 3, the plug-in block 21 will be plugged into the plug-in port 23, and the snap-in block 29 will be snap-fitted into the snap-fitting port 22, so that the display board 6 is more stable in the display frame 3 and will not fall out easily. When the wedge-shaped movable block 27 is squeezed, the wedge-shaped movable block 27 can slide through the T-shaped slide bar 25 and the sliding sleeve 26, so that the wedge-shaped groove 30 can push the two wedge-shaped movable blocks 27 to compress the spring three 28 to move closer to each other, so that the engaging block 29 will shrink toward the cavity 24, and the shrinkage is difficult and more complete, which facilitates the insertion of the plug-in block 21 into the plug-in interface 23 and increases the difficulty of pulling out the plug-in block 21, so that the sealing plate 8 is more stable in the display frame 3, and the anti-slip block 31 prevents the engaging block 29 from slipping out of the cavity 24.

[0034] Furthermore, a pull handle 32 is fixedly connected to the right side of the cover plate 8 for convenient holding, so as to pull out the display plate 6 inside the display frame 3, thereby facilitating the modification of data on the paper used to record the progress of the project.

[0035] Furthermore, notches 33 are provided on opposite sides of the two blocks 11, and a stop block 34 is fixedly connected above the front surface of the pressure rod 12. The front surface of the stop block 34 fits against the rear surface of the stop block 11, and the width of the stop block 34 is smaller than the width of the notch 33. When the pressure rod 12 is rotated to a vertical state, the stop block 34 presses against the rear surface of the stop block 11, so that the top of the pressure rod 12 presses the spring 13 backwards, so that the pressure rod 12 fits more closely against the inner rear surface of the display slot 9, thereby being able to press the paper more tightly.

[0036] Furthermore, the bottom end of the moving block 15 is fixedly connected to a vertical rod 35, and the bottom end of the vertical rod 35 passes through the lower surface of the movable groove 14 and is fixedly connected to the inner side of the L-shaped stop block 17, so that the moving block 15 drives the L-shaped stop block 17 to move more stably, and the moving block 15 will not fall out of the movable groove 14.

[0037] Furthermore, anti-slip grooves are provided between the opposite sides of the wedge-shaped pressing groove 18 and the wedge-shaped pressing block 19, so that when the wedge-shaped pressing block 19 is engaged inside the wedge-shaped pressing groove 18, it is tighter and less likely to slide, thereby avoiding the problem of being affected by the spring 13 pushing the pressure rod 12 forward, so that when the pressure rod 12 presses the paper, the wedge-shaped pressing block 19 falls out of the wedge-shaped pressing groove 18, affecting the pressure rod 12 pressing the paper.

[0038] Furthermore, a sealing gasket 36 is fixedly connected to the inner wall of the engaging opening 22 to increase the friction between the engaging block 29 and the engaging opening 22 and reduce the gap, so that the engaging is tighter.

[0039] In summary, the working process of the present invention is as follows: when the device is used, the device is prevented in the corresponding position by the bottom plate 1, and the support rod 2 is adjusted to a suitable height for easy viewing. The paper recording the progress of the project pasted inside the display frame 3 can be viewed through the glass observation window 4. When the paper is put in, the display board 6 is pulled out of the display frame 3 through the sealing plate 8, and then the paper recording the progress of the project is attached to the display slot 9, and is pressed by the pressure rod 12. The display board 6 slides in the slide slot 5 through the anti-slip rod 7 to prevent the display board 6 from slipping out. When the pressure rod 12 is used, it is rotatably connected with the rotating column 10, so that the horizontal pressure rod 12 is rotated to a vertical state, so that the two pressure rods 12 respectively press the two sides of the paper. When the pressure rod 12 is rotated to a vertical state, the L-shaped stop block 17 at the bottom passes through the movable slot 1 provided 4. The moving block 15 and the second spring 16 can be firmly pressed against the inner bottom of the display slot 9, so that the pressure rod 12 is more stable when pressing the paper, and will not deviate to affect the viewing. When the pressure rod 12 is rotated to the vertical state to press the paper, the wedge-shaped pressing groove 18 and the wedge-shaped pressing block 19 are set, which will push the pressure rod 12 to move backward, and the paper can be pressed more tightly. The spring 13 will push the pressure rod 12 to move forward and press against the rear surface of the stopper 11 in a normal state, so that when the wedge-shaped pressing block 19 is not engaged in the wedge-shaped pressing groove 18, the gap between the pressure rod 12 and the display slot 9 is larger, which is convenient for putting in the paper, and then pressing it tightly through the pressure rod 12, and the two pressure rods 12 in the horizontal state will be pressed against each other through the two L-shaped pressing blocks 17, so as to horizontally block the top of the display slot 9 for storage, which is convenient for putting in the paper.
