Description

Technical Field

[0001] The utility model relates to the technical field of glass cover plates, and more specifically to a glass fiber reinforced plastic pultruded cover plate which is easy to splice. Background Art

[0002] FRP cover is a cover made of fiberglass. Although it is not as strong as some metal covers, its anti-corrosion performance is far beyond the reach of metal covers. Its load-bearing capacity is far superior to wooden and plastic covers, and its designability and safety performance are far superior to the above-mentioned covers. FRP cover is generally used in sewage channels, and the covers are generally put one by one directly on the top of the channel.

[0003] The current fiberglass pultruded cover plate that is easy to splice, such as the "A fiberglass pultruded cover plate that is easy to splice" proposed in patent No. 202321891237.4, includes a cover plate body, a first side support, a first limit plate and a second limit plate. The front side of the outside of the cover plate body is provided with a first side support, and the center position of the outside of the first side support is provided with a first groove. The rear side of the outside of the cover plate body is provided with a first limit plate, and the center position of the outside of the first limit plate is provided with a first protrusion, and the left side of the outside of the cover plate body is provided. The utility model connects multiple top covers to each other, and then the first protrusions and the first grooves of the two top covers are connected to each other, or the second protrusions and the second grooves are connected to each other, so that the structure is simple and easy to splice, thereby avoiding the problem of easy movement of a single top cover, preventing the cover plate from moving out of the channel, thereby causing garbage to fall into the channel.

[0004] The existing glass fiber reinforced plastic pultruded cover plate that is easy to splice is connected by a T-shaped protrusion and a corresponding groove. Although it can achieve the purpose of splicing multiple glass cover plates, in actual use, after the T-shaped protrusion in the device is fixed in the corresponding groove in another glass cover plate, the cover plates are not easy to separate and not easy to move horizontally, but the cover plates are easy to move vertically as a whole, resulting in misalignment of the splicing between the cover plates, and it is difficult to limit the installed cover plate, which is inconvenient to use. Therefore, there is an urgent need to improve the technology of the glass fiber reinforced plastic pultruded cover plate structure that is easy to splice to improve this equipment. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a glass fiber reinforced plastic pultruded cover plate that is easy to splice. When the glass fiber reinforced plastic pultruded cover plate that is easy to splice is used, the card block of the glass cover plate can be moved into the open groove of another glass cover plate, and then the glass cover plate is moved downward, so that the glass cover plate drives the card block to move to the inside of the card groove, so that the glass cover plates are not easily separated from each other. After the multiple glass cover plates are spliced, the rotating rod can be rotated, and the first transmission rod and the second transmission rod can be rotated at the same time through the transmission mechanism, so that the rectangular block moves from the rectangular groove into the open groove to abut against the card block, and the card block is limited, so that the spliced ​​glass cover plates are locked horizontally and vertically, so as to avoid relative movement between the glass cover plates and affect the splicing effect, and it is convenient to use.
