Abstract

The utility model discloses a hinge device has solved current hinge device and connecting piece welding time welding seam big and concentrated, and welding deformation is big, produces the problem of the defect of wearing easily. The technical scheme includes that the hinge comprises an upper hinge, a lower hinge and a pin shaft, the upper hinge is an arc-shaped groove with an upward opening, the lower hinge comprises a pipe section of an upper section and a connecting section of a lower section, and the pin shaft is inserted in a pin shaft hole formed after the pipe section and the arc-shaped groove are correspondingly installed. The utility model discloses simple structure, welding seam are little, welding deformation is little, effectively avoid welding and wear, the reliability is high.

Description

Hinge means

Technical field

The utility model relates to a kind of hinge means.

Background technology

The existing gusset boxboard of cargo vehicle and being connected of base plate connect by hinge usually.Hinge is comprised of upper hinge, lower hinge and bearing pin, upper hinge is welded on the gusset boxboard usually, lower hinge generally is connected on base plate by rivet or bolt, the upper hinge of gusset boxboard is connected cooperation by bearing pin with the lower hinge of base plate, the gusset boxboard can rotate around bearing pin, thereby realizes the function that lorry gusset boxboard opens and closes.Be welded on the upper hinge on the gusset boxboard, its welding portion is generally sheet, expect that thick is 3mm～5mm, and being generally sheet rolling, the gusset boxboard forms, expect that thick is 1mm～2mm, both expect thickly to differ larger, in welding, because weld seam is concentrated greatly, welding deformation amount is large, easily produce the defective of burn-through, and the frequency that opens and closes due to lorry gusset boxboard is very high, and in the switching process, the part of the force all concentrates on the welding portion of upper hinge and gusset boxboard, so after long-time the use, this welding portion also easily tears and rust is worn.

Summary of the invention

The purpose of this utility model is in order to solve the problems of the technologies described above, provide a kind of simple in structure, weld seam is little, welding deformation amount is little, effectively avoid burn-through, hinge means that reliability is high.

Technical scheme comprises upper hinge, lower hinge and bearing pin, and described upper hinge is opening up deep-slotted chip breaker, and described lower hinge comprises the pipeline section of epimere and the linkage section of hypomere, and corresponding the installation in the rear pin shaft hole that forms of described pipeline section and deep-slotted chip breaker is plugged with bearing pin.

Have the mounting groove of installing for deep-slotted chip breaker in the middle part of the pipeline section of described lower hinge.

The one outwardly-bent camber of end of described deep-slotted chip breaker.

The linkage section of described lower hinge has installing hole, is used for fixedly mounting with connector (as platform floor).

Due to the deep-slotted chip breaker opening upwards, possessed the two ends that are positioned at opening part, thereby increased stressed, make the solder joint of itself and connector (as cargo vehicle compartment gusset boxboard) no longer concentrated, optimize position while welding, and, the one outwardly-bent camber of end of deep-slotted chip breaker distributes solder joint better.

By the ringent design to the upper hinge upper end, can optimize position while welding, improve weld strength, increase the stress point in connector switching process, efficiently solve sheet upper hinge weld seam and concentrate the negative issue that brings, and have not yielding, good rigidly, sturdy and durable, make advantage easy for installation, can be widely used in cargo vehicle compartment gusset boxboard and base plate be connected or other need to use hinged parts.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further explained explanation:

With reference to Fig. 1-Fig. 5, technical scheme comprises upper hinge 1, lower hinge 2 and bearing pin 3, and described upper hinge 1 is opening up deep-slotted chip breaker 1.3, the outwardly-bent camber of right-hand member 1.2 of described deep-slotted chip breaker 1.3.Described lower hinge 2 comprises the pipeline section 2.1 of epimere and the linkage section 2.2 of hypomere, and corresponding the installation in the rear pin shaft hole 4 that forms of described pipeline section 2.1 and deep-slotted chip breaker 1.3 is plugged with bearing pin 3.Pipeline section 2.1 middle parts of described lower hinge 2 have the mounting groove 2.3 of installing for deep-slotted chip breaker 1.3.The linkage section 2.2 of described lower hinge 2 has installing hole 2.4.The steel plate punched bending that described upper hinge 1 and lower hinge 2 are 3mm～5mm for thickness forms.

So that cargo vehicle compartment gusset boxboard and base plate carry out the hinged example that is, left end 1.1 and the right side 1.2 of upper hinge 1 are welded with cargo vehicle gusset boxboard respectively, lower hinge is connected with truck bed through installing hole by bolt.Finally realize the chain connection of compartment gusset boxboard and base plate.

Claims (4)
