Embodiments of the present invention are described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, an embodiment of the present invention provides a reinforcing structure 100, where the reinforcing structure 100 includes two parallel supporting members 10, two parallel supporting members 12, and a connecting member 20. Two parallel support elements 10 and two parallel support elements 12 are connected to each other as shown in fig. 1 around a closed loop area 11. The connection member 20 connects the adjacent support member 10 and support member 12, and the connection member 20 has an elastic portion 21, and the elastic portion 21 is used to provide elastic force toward the inside of the closed loop area 11.
In the prior art, the support 10 is typically welded using a welding technique, and during use, the support 10 is typically subjected to forces directed into the closed loop region 11, and the support 10 is subjected to forces that, over time, arc-shaped deformations until fracture. Compared with the prior art, the embodiment of the invention uses the connecting piece 20 to connect the adjacent supporting pieces 10, the elastic portion 21 of the connecting piece 20 can provide the elastic force towards the inside of the closed loop region 11, and the supporting pieces 10 connected with the connecting piece 20 can displace along with the deformation of the elastic portion 21, so that each supporting piece 10 can displace relatively without breaking, therefore, the reinforcing structure 100 provided by the embodiment of the invention is not easy to break and has long service life.
It should be appreciated that while the present invention is not limited to four supports 10, the reinforcing structure 100 may also include three supports 10 and more than four supports 10 without departing from the scope of the present invention, and those skilled in the art may be configured as desired. In this embodiment, the adjacent supporting members 10 and 12 are connected by the connecting member 20, and in other embodiments, one end of the supporting member 10 may be connected to one supporting member 12 by the connecting member, and the other end of the supporting member 10 may be directly welded to the other supporting member 12.
Further, as shown in fig. 1 and 2, the connector 20 has a first connection portion 22 and a second connection portion 23, and the first connection portion 22 and the second connection portion 23 are respectively used to connect the adjacent support 10 and the support 12. The elastic portion 21 connects the first connection portion 22 and the second connection portion 23. Those skilled in the art can make the settings according to actual needs.
Preferably, as shown in fig. 1 and 2, the elastic portion 21 is a plate body, and the elastic portion 21 is perpendicular to a plane where axes of the adjacent supporting members 10 and 12 lie. With this arrangement, when the supporting member 12 is subjected to a force, the elastic portion 21 connected to the supporting member 10 will deform more, and the elastic portion 21 can bear more force on the supporting member 12, so that the supporting member 12 will not break after a larger relative displacement, and the service life of the reinforcing structure 100 will be longer. The elastic portion 21 may be configured to be elastically deformable, such as a spring, and may be provided as desired by those skilled in the art without departing from the scope of the present invention.
Further, the thickness of the elastic portion 21 ranges between 1mm and 3 mm. The thickness of the elastic portion 21 is the thickness of the plate body of the plate-shaped elastic portion 21, that is, the thickness of the elastic portion 21 in the bending direction when it is bent. Those skilled in the art can make the settings according to actual needs.
Preferably, as shown in fig. 1 and 2, the first connecting portion 22 is inserted around the support member 10 adjacent thereto, and the second connecting portion 23 is partially inserted into one end of the support member 12 adjacent thereto. While welding the adjacent support members 10 and 12 is required in the prior art, the present invention simply requires a ferrule and a socket to connect the support members 10 and 12 to each other, which simplifies the processing of the reinforcing structure 100, and can be set by those skilled in the art according to actual needs.
Further, as shown in fig. 1 and 2, the first connecting portion 22 has a fold 221 thereon, and the fold 221 abuts against the support member 10 of the ferrule of the first connecting portion 22. The folds 221 allow for a greater friction between them and the sleeved support 10, and the first connection portion 22 can be more easily clipped onto the support 10, which can be set by a person skilled in the art according to the actual needs.
As shown in fig. 1 and 2, the second connecting portion 23 is inserted into the support 12 at one end thereof and has a serration structure 231, and the tooth tip of the serration structure 231 abuts against the inner periphery of the support 12. Such provision of the second connecting portion 23 enables easier insertion of the support 12, which can be provided according to actual needs by a person skilled in the art.
In addition, as shown in fig. 1 and 2, the reinforcing structure 100 includes two parallel supporting members 10 and two parallel supporting members 12, wherein adjacent supporting members 10 are perpendicular to the supporting members 12, two end sides of one pair of parallel supporting members 10 are connected with the other pair of parallel supporting members 12 through connecting members 20, a second connecting portion 23 is at least partially inserted into end sides of the one pair of parallel supporting members 12, and a first connecting portion 22 is sleeved on the periphery of the other pair of parallel supporting members 10. In the field of double-layer plastic uptake coaming boxes, a pair of parallel support pieces 10 are propped between side stoppers of a cover plate, and a closed loop area 11 formed by surrounding two parallel support pieces 10 and two parallel support pieces 12 covers the central position of the cover plate, and the support pieces 10 and 12 are fixed in four directions, so that distortion in the use process can be prevented. In addition, during use, the cover plate is contracted towards the center direction, the supporting members 12 are subjected to the force towards the inside of the closed loop area 11, the connecting members 20 are used for connecting the adjacent supporting members 12, the elastic parts 21 of the connecting members 20 can provide the elastic force towards the inside of the closed loop area 11, and the supporting members 12 connected with the connecting members 20 can displace along with the deformation of the elastic parts 21, so that the supporting members 10 and 12 can displace relatively without breaking, and the reinforcing structure 100 provided by the embodiment of the invention is not easy to break and has long service life. The connector 20 can neutralize a portion of the shrinkage offset due to its elasticity and structure, so as to avoid the support 10 from breaking the cover plate.
As shown in fig. 3,4 and 7, another embodiment of the present invention further provides a cover plate, which includes a first cover 40, a second cover 50 and a reinforcing structure 100. The second cover 50 is in covering connection with the first cover 40. The reinforcing structure 100 is sandwiched between the first cover 40 and the second cover 50.

Further, the service life of the cover plate using the reinforcing structure 100 is also longer.
Preferably, as shown in fig. 4, the first cover 40 and the second cover 50 are hermetically connected to form the cavity 30, and the reinforcing structure 100 is disposed in the cavity 30. The cavity 30 is arranged, so that the weight of the cover plate can be reduced, and the cover plate can be light in weight and high in compression resistance.
