The strengthening ribs 35 in this embodiment are disposed at the symmetrical center line of the L-shaped drawstring support.
The two drawstrings respectively penetrate through the corresponding mounting through holes 34 through the fastening bolts on the two drawstrings to be screwed and fixed with the fastening nuts, at the moment, the tensioning force of the two drawstrings to the gas cylinder is respectively overlapped with the supporting force of the arc-shaped supporting part correspondingly supporting the gas cylinder body, the phenomenon that shearing torque is generated due to the fact that the tensioning force of the two drawstrings to the gas cylinder is respectively offset from the supporting force of the arc-shaped supporting part correspondingly supporting the gas cylinder body is avoided, and the drawstrings are fixed more safely and reliably.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, but any modifications or equivalent variations made in accordance with the technical spirit of the present invention are within the scope of the present invention as claimed.
The invention has the advantages that: firstly, two auxiliary beams are removed on the basis of ensuring the connection strength of the vehicle-mounted bottle frame and the automobile frame, so that the overall structure of the vehicle-mounted bottle frame is more compact, the overall quality is reduced, and the cost is effectively reduced; the arrangement of the L-shaped reinforcing plate 4 further improves the strength of the vehicle-mounted bottle frame; due to the arrangement of the structures of the stamping holes 5 and the corresponding stamping blanking plates 51, when the vehicle-mounted bottle frame passes through the through holes on the connecting plates on the vehicle frame through a plurality of bolts, corresponds to the first connecting holes 111, and screws with the corresponding nuts 6 with gaskets after corresponding to the stamping holes 5, if the upper and lower positions of the corresponding nuts 6 with gaskets have certain deviation, the nuts 6 with gaskets correspondingly positioned at the deviation positions can be conveniently adjusted in the upper and lower positions, so that the bolts can be accurately and conveniently screwed and fixed with the corresponding nuts 6 with gaskets; and fourthly, each drawstring support 3 is arranged on the side plate 14 corresponding to the saddle 1 and the side folded edge 74 of the reinforcing support 7, when the two drawstrings respectively pass through the corresponding mounting through holes through the fastening bolts on the two drawstrings to be fastened with the fastening nuts in a rotating manner, the tensioning force of the two drawstrings on the gas cylinder is respectively overlapped with the supporting force of the corresponding arc-shaped support part for supporting the gas cylinder body, the phenomenon that the shearing torque is generated because the tensioning force of the two drawstrings on the gas cylinder is respectively offset from the supporting force of the corresponding arc-shaped support part for supporting the gas cylinder body is avoided, and the drawstrings are fixed more safely and reliably.
