The transverse reinforcing ribs are arranged at the edges of the outer surfaces of the upper cover and the lower cover.
The longitudinal reinforcing ribs are arranged in the middle of the outer surfaces of the upper cover and the lower cover.
The internal reinforcing ribs are arranged in the center positions of the outer surfaces of the upper cover and the lower cover.
The fastening bolt consists of a screw rod and a nut, one end of the screw rod, which is not provided with the screw teeth, is provided with a fixing hole vertical to the screw rod, and the fixing block is cylindrical and has the same diameter as the screw rod.
A limiting groove is arranged in each of the first clamping groove and the second clamping groove; the fixed block is clamped in the limit groove.
The shape of the internal reinforcing rib is a nearly rectangular shape with two long sides being circular arcs.
Compared with the prior art, the utility model discloses following beneficial effect has: 1. the utility model ensures the overall strength of the upper and lower cover bodies by arranging the transverse reinforcing ribs, and ensures the strength of the main stress points and the exposed points of the upper and lower cover bodies by arranging the longitudinal reinforcing ribs and the internal reinforcing ribs, thereby overcoming the problem that the fastener is easy to deform and break in the use process, prolonging the service life of the fastener, ensuring the construction safety and simultaneously reducing the replacement and maintenance cost of the fastener; 2. the utility model has the advantages that the fixing block of the fastening bolt can be well clamped in the limiting groove by arranging the limiting groove, so that the phenomenon that the fastening bolt slides and rotates in the clamping groove is avoided, and the use is more convenient; 3. the internal reinforcing ribs of the utility model can also be used as trademark holding areas of manufacturers, and the manufacturers can directly set trademarks of companies as the internal reinforcing ribs on the upper cover body and the lower cover body by changing the moulds, thereby saving the production cost; 4. the utility model discloses still have characteristics such as simple structure, reasonable in design, convenient to use, security height, use the utility model discloses a product not only can improve work efficiency, assurance constructor's that moreover can be better safety.
