Detailed Description
As shown in figures 1 to 6, a glass fiber reinforced plastic explosion-proof centrifugal fan combined fastening device adopts a brand-new structural design, the overall structure is simpler, the components combined in an inclined mode can be matched for reinforcement and combination when being assembled, the connection strength during matching can be improved, accurate combination and convenient assembly can be provided for assembly positions during installation, the combination efficiency during assembly is higher, the combination strength of the connection positions is effectively reinforced, the overall safety during later use is better guaranteed, and the overall durability during use is more reliable. It includes rectangle main part installation cooperation connecting plate 1, the stable spliced pole 2 of the inverted cone shape installation location combination that distributes about main part installation cooperation connecting plate 1's lower extreme is equipped with, and the combination convenience when can ensure this device and mate is better, and joint strength is also more reliable. The front of main part installation cooperation connecting plate 1 is equipped with about the distribution and for the fastening cooperation calibration spread groove 3 of symmetry, can carry out accurate inseparable combination with the part of slope mating combination together, can play the effect of cooperation calibration, has also improved the structural strength who cooperates hookup location simultaneously. Fastening cooperation calibration spread groove 3 will the terminal surface runs through completely about 1 main part installation cooperation connecting plate, the direction of fastening cooperation calibration spread groove 3 is the slope downwards, cylindrical main part locking fixed connection hole 4 that distributes about 1 upper end of main part installation cooperation connecting plate is equipped with, controls two the length direction's of fastening cooperation calibration spread groove 3 contained angle is 74 degrees, can carry out accurate built-up connection with the cooperation structure of composite position.
Preferably, the projection of the mounting, positioning, combining and stabilizing connecting column 2 in the front-back direction is located at the middle position of the projection areas of the left fastening, matching and calibrating connecting groove 3 in the front-back direction, so that the matching strength during the combining and mounting can be further improved, and the safety and stability of the combining and connecting can be firmer.
