Abstract
Description
Technical Field
[0001] This utility model relates to the field of cover plate technology, and in particular to a modular lightweight high-strength cover plate. Background Technology
[0002] Currently, Chinese Patent Publication No. CN115162918B discloses an openable lifting port cover and its working method, including a support frame, a cover plate, and telescopic frames rotatably disposed on the support frame on both sides of the cover plate in the vertical direction. The telescopic frames include a first connecting rod and a telescopic frame. This discloses a cover plate with a conventional structure. However, the conventional cover plate is connected to the support frame by a gas spring. The cover plate stands vertically behind the support frame by the gas spring, which is easily affected by external forces and can easily tip over and rotate. Furthermore, the gas spring needs to be regularly maintained and its airtightness checked. Utility Model Content
[0003] Therefore, in view of the above problems, this utility model proposes a modular lightweight high-strength cover plate, which solves the above problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a modular lightweight high-strength cover plate, comprising a frame, a recessed portion disposed on the inner side of the frame, a stepped recessed portion disposed between the frame and the recessed portion, a cover plate disposed on both sides of the recessed portion of the frame for sealing the frame, a rotatable skeleton disposed on the front and rear sides of the stepped recessed portion of the frame, a side plate disposed on the top surface of the skeleton, and an angle adjustment mechanism disposed between the skeleton and the stepped recessed portion. The angle adjustment mechanism includes a lower adjustment block connected to the stepped recessed portion of the frame, an upper adjustment block cooperating with the lower adjustment block and connected to the skeleton and the side plate, and an adjustment bolt disposed on the top of the lower adjustment block. The lower adjustment block is provided with locking rods spaced below the adjustment bolts. The upper adjustment block is provided with a rectangular groove in the middle that slides with the adjustment bolts. When the top of the rectangular groove of the upper adjustment block contacts the locking rod, the bottom of the upper adjustment block is provided with a slot that cooperates with the locking rod.
[0005] Furthermore, the cover plate is provided with a folding plate on the side away from the frame, and the front and rear sides of the folding plate are provided with rotating wheels that fit into the recessed part, and the front and rear sides of the cover plate fit into the recessed part.
[0006] Furthermore, the middle surface of the cover plate and the folding plate is provided with a galvanized perforated plate.
[0007] Furthermore, the side plate surface is provided with multiple annular holes.
[0008] Furthermore, the surfaces of the cover plate and the folding plate are coated with anti-corrosion paint.
[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:
[0010] This modular, lightweight, high-strength cover plate features an angle adjustment mechanism. Under the weight of the side plate, the groove at the bottom of the upper adjusting block engages with the locking rod of the lower adjusting block. To open the side plate, rotate it upwards, then pull it upwards. This causes the upper adjusting block to move upwards until the bottom of its rectangular groove contacts the adjusting bolt. Moving the side plate vertically downwards, the groove at the bottom of the upper adjusting block engages with the locking rod, and the top of the rectangular groove contacts the adjusting bolt. The side plate is then vertically fixed to the lower adjusting block via the upper adjusting block. When closing the side panel, first push the cover plate down to close it in the recessed part of the frame, then pull the side panel upward. The bottom of the rectangular groove on the side panel fits with the adjusting bolt. Since the slot at the bottom of the side panel disengages from the locking rod, the side panel can rotate automatically at this time. Then rotate the side panel further, and the side panel can close on the cover plate. Compared with the original gas spring fixing method, it is more stable, the side panel is not easy to flip down and rotate, and the cost is lower than that of the gas spring. It is also simple to maintain. It solves the problem that the cover plate is easily flipped down and rotated by external force after being vertically erected by the gas spring behind the support frame, and the gas spring requires regular maintenance and airtightness testing.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0021] refer to Figures 1 to 9 This embodiment provides a modular lightweight high-strength cover plate, including a frame 1, a recess 2 located inside the frame 1, a stepped recess 3 located between the frame 1 and the recess 2, cover plates 4 located on both sides of the recess 2 of the frame 1 for sealing the frame 1, a frame 5 rotatably located on the front and rear sides of the stepped recess 3 of the frame 1, a side plate 6 located on the top surface of the frame 5, and an angle adjustment mechanism 7 located between the frame 5 and the stepped recess 3. The angle adjustment mechanism 7 includes a lower adjustment block 70 connected to the stepped recess 3 on the frame 1. 1. An upper adjusting block 702 that cooperates with the lower adjusting block 701 and is connected to the frame 5 and the side plate 6, and an adjusting bolt 703 located on the top of the lower adjusting block 701. The lower adjusting block 701 is provided with a locking rod 704 at intervals below the adjusting bolt 703. The upper adjusting block 702 is provided with a rectangular groove 705 in the middle that slides with the adjusting bolt 703. When the top of the rectangular groove 705 of the upper adjusting block 702 contacts the locking rod 704, the bottom of the upper adjusting block 702 is provided with a slot 706 that cooperates with the locking rod 704.
[0022] Under the force of gravity, the slot 706 at the bottom of the upper adjusting block 702 is fixed to the locking rod 704 of the lower adjusting block 701. When the side plate needs to be opened, rotate the side plate upward 90 degrees, and then pull the side plate upward. The side plate moves the upper adjusting block upward, and the bottom of the rectangular slot of the upper adjusting block contacts the adjusting bolt. Then move the side plate vertically downward. After the side plate moves downward, the slot at the bottom of the upper adjusting block contacts the locking rod, and the top of the rectangular slot of the side plate contacts the adjusting bolt. The side plate can be vertically fixed to the lower adjusting block by the upper adjusting block. When the side plate needs to be closed, first push the cover plate down to close it in the recessed part of the frame, and then pull the side plate upward. The bottom of the rectangular slot on the side plate is in contact with the adjusting bolt. Since the slot at the bottom of the side plate is disengaged from the locking rod, the side plate can rotate automatically. Then rotate the side plate 90 degrees, and the side plate can close on the cover plate. Compared with the original gas spring fixing method, it is more stable, the side plate is not easy to flip down and rotate, and the cost is lower than that of the gas spring and the maintenance is simple.
[0023] The cover plate 4 is provided with a folding plate 4a on the side away from the frame 1. The front and rear sides of the folding plate 4a are provided with rotating wheels 8 that fit into the recessed part 2. The front and rear sides of the cover plate 4 fit into the recessed part 2.
[0024] When used on long frames, when the cover is folded down, the folding plate on one side of the cover will also rotate and unfold until the cover is attached to the frame. The cover and the folding plate will then lie flat on the frame. When the cover is pulled up, the folding plate moves on the frame via pulleys on both sides. After the cover is rotated 90 degrees, the folding plate will be attached to one side of the cover, which is beneficial for the use of long frames.
[0025] The middle surface of the cover plate 4 and the folding plate 4a is provided with a galvanized perforated plate 4b. The galvanized perforated plate is located in the middle of the top surface of the cover plate and the folding plate. The side plate covers the front and rear sides, which can support the top surface of the cover plate and the folding plate and facilitate the user to walk back and forth between the cover plate and the folding plate.
[0026] The side plate 6 has multiple annular holes 9 on its surface. The annular holes have a certain anti-slip effect and can drain water when it is necessary to clean up the water.
[0027] The surfaces of the cover plate 4 and the folding plate 4a are coated with anti-corrosion paint, which helps to improve the corrosion resistance of the cover plate and the folding plate and extend their service life.
