The mounting grooves 11 are uniformly formed in the carriage bottom plate 1, the mounting lugs 12 are uniformly arranged at the lower ends of the carriage front plate 81, the carriage left side plate 21 and the carriage right side plate 31, the mounting grooves 11 are matched with the mounting lugs 12, nuts a13 are welded inside the mounting lugs 12, mutually overlapped slotted holes are formed in the mounting grooves 11 and the mounting lugs 12, the slotted holes are opposite to the nuts a13, bolts a14 are further installed in the slotted holes, the bolts a14 penetrate through the slotted holes to be matched and fixed with the nuts a13, the mounting lugs 12 are further provided with buckle plates 15, and the buckle plates 15 are buckled on the side face of the carriage bottom plate 1.

Through the above-mentioned installation lug 12 and the cooperation of installation recess 11 on the carriage bottom plate 1 lock joint, rethread bolt a14 passes the slotted hole of coincide each other and is connected fixedly with the cooperation of the inside welded nut a13 of installation lug 12 for carriage front bezel 81, carriage left side board 21 and carriage right side board 31 can be installed on carriage bottom plate 1 fast, and the cooperation distance between carriage front bezel 81, carriage left side board 21 and the carriage right side board 31 is injectd, be favorable to carriage left side board subassembly 2, each inside sub-group spare of carriage right side board subassembly 3 and carriage front bezel subassembly 8 and the cooperation installation between them.

The fixing mechanism 53 is further provided with a fixing buckle plate 54, two sets of nut mechanisms a55 are welded on the inner side walls of the convex buckling plate 51 and the concave buckling plate 52 respectively, the fixing buckle plate 54 is buckled on the outer side walls of the convex buckling plate 51 and the concave buckling plate 52, and two sets of bolt mechanisms a56 are arranged to penetrate through the fixing buckle plate 54 and the convex buckling plate 51 or the concave buckling plate 52 to be connected with the nut mechanisms a55 in a matching mode.

Through the matching of the nut mechanism a55 and the bolt mechanism a56 on the convex buckling plate 51 and the concave buckling plate 52, the fixed buckle plate 54 is respectively fixed on the convex buckling plate 51 and the concave buckling plate 52, so that the convex buckling plate 51 and the concave buckling plate 52 are further tensioned and fixed by the fixed buckle plate 54 after concave-convex matching, and the joint is more beautiful.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
