Description

Carriage and chassis connection structure Technical Field The utility model relates to the technical field of vans, in particular to a carriage and chassis connecting structure. Background At present, the existing multi-purpose truck cargo compartment is connected with the chassis through bolts, nuts are usually embedded in the cargo compartment reinforcing ribs, the accuracy requirement of the embedded positions of the nuts in the cargo compartment is high, and the welding requirement of the nuts is high. Because the goods railway carriage or compartment is often exposed in environment such as rainwater, salt fog, chemicals, if pre-buried nut is sealed inadequately, easy rust-forming leads to reduce intensity (like ordinary carbon steel nut can shorten more than 50% in humid environment life-span), if the nut appears not hard up, then need dismantle goods railway carriage or compartment inside lining or covering and just can overhaul the nut, increase cost of labor and time. Disclosure of utility model In view of the above-mentioned drawbacks of the prior art, the present utility model aims to provide a carriage and chassis connection structure, which is used for solving the problems of high labor and time cost caused by the need of disassembling a carriage lining or covering when the nuts are easy to rust and loosen and overhauling in the prior art that the nuts and chassis bolt connection mode is embedded in the carriage reinforcing ribs of the conventional van. To achieve the above and other related objects, the present utility model provides a cabin and chassis connection structure, comprising: The chassis is provided with a plurality of supports, and the supports are provided with first through holes; The base plate framework is correspondingly provided with a connecting seat, a second through hole is formed in the connecting seat corresponding to the first through hole, and the first through hole and the second through hole are used for penetrating through a locking component to connect the connecting seat and the support; And the carriage is connected with the bottom plate framework. Optionally, the bottom plate skeleton includes perpendicular crisscross longeron and the crossbeam of connecting, longeron is unanimous with the length direction of chassis. Optionally, the connection seats are all arranged on the longitudinal beam. Optionally, the cross sections of the longitudinal beam and the cross beam are of C-shaped structures, and the longitudinal beam and the cross beam are welded and fixed. Optionally, the cross section of the connecting seat is of an L-shaped structure. Optionally, the connecting seat comprises a first connecting portion and a second connecting portion, the second through hole is formed in the first connecting portion, and the second connecting portion is welded and fixed with the longitudinal beam. Optionally, a reinforcing structure is disposed between the first connecting portion and the second connecting portion. Optionally, the reinforcement structure includes triangular reinforcement plates symmetrically disposed between the first connection portion and the second connection portion along a length direction of the longitudinal beam. Optionally, the locking component comprises a bolt and a self-locking nut, the bolt passes through the second through hole and the first through hole to be in threaded connection with the self-locking nut, the head of the bolt is in abutting fit with the first connecting part, and the self-locking nut is in abutting fit with the support. Optionally, a shock pad is arranged between the first connecting part and the support, a first flat pad is arranged between the head of the bolt and the first connecting part, and a second flat pad is arranged between the self-locking nut and the support. The utility model has the advantages that the carriage is connected with the chassis through the bottom plate framework, the connecting seat is arranged on the bottom plate framework corresponding to the support on the chassis, the connection is realized through the locking component penetrating through the connecting seat and the through hole on the support, the nut embedded in the carriage is avoided, if the locking component is loose or rusted, the locking component can be overhauled without disassembling the carriage lining or the covering piece because the carriage is connected with the chassis through the bottom plate framework, and therefore, the labor and time cost required by overhauling can be effectively reduced.
