Description of the drawings:
fig. 1 is a schematic view of the armrest turning-over limiting mechanism of the present invention.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
The handrail overturning limiting mechanism comprises a handrail assembly 1, a damping mounting plate 2, a handrail left side plate 3, a handrail rotating moving shaft 4, a handrail rotating fixed shaft 5, a handrail right side plate 6, a fixing screw 7 and a handrail outer side support cover 8, wherein a first fan-shaped waist hole 20 and a first through hole 21 positioned on one side of the first fan-shaped waist hole 20 are formed on the damping mounting plate 2, a plurality of clamping blocks 22 are convexly formed on the left side surface of the damping mounting plate 2, the handrail left side plate 3 is mounted on the left side of the damping mounting plate 2, a second fan-shaped waist hole 30 aligned with the first fan-shaped waist hole 20 in the left-right direction and a second through hole 31 positioned on one side of the second fan-shaped waist hole 30 and aligned with the first through hole 21 are formed on the handrail left side plate 3, and a clamping groove 32 which is mounted with the clamping blocks 22 together is formed on the handrail left side plate 3.
The right armrest side plate 6 is formed with a third fan-shaped waist hole 60 and a third through hole 61 located at one side of the third fan-shaped waist hole 60, and the armrest outer support cover 8 is mounted on the outer side of the right armrest side plate 6 and is formed with a notch portion 80 that is communicated with the third fan-shaped waist hole 60 and the third through hole 61.
The left side of the handrail rotating fixed shaft 5 is arranged in the first through hole 21 and the second through hole 31 in a penetrating manner, the right side of the handrail rotating fixed shaft 5 extends into the third through hole 61, a plastic part (not shown) is arranged on the right side of the handrail rotating fixed shaft 5, and the handrail rotating fixed shaft 5 and the plastic part are fixedly arranged together through a fixing screw 7.
The left side of the armrest rotating shaft 4 is inserted into the first fan-shaped waist hole 20 and the second fan-shaped waist hole 30, and the right side of the armrest rotating shaft 4 is inserted into the third fan-shaped waist hole 60 and the notch portion 80.
The armrest assembly 1 comprises an armrest framework, and an armrest rotating shaft 4 and an armrest rotating fixed shaft 5 are welded together with the armrest framework.
In the handrail overturning limiting mechanism, the handrail left side plate 3 and the handrail right side plate 6 are both made of SAPH440 materials. The diameter of the armrest rotating shaft 4 is 7mm, the minimum limiting clearance of the waist-shaped hole at the closed state is 5.2mm, and the minimum limiting clearance of the waist-shaped hole at the open state is 5mm, which are both smaller than the diameter of the armrest rotating shaft 4, so that the armrest rotating shaft 4 is prevented from rotating.
In order to prevent the handrail rotating shaft 4 from wearing the damping mounting plate 2 in the rotating process, the damping mounting plate 2 is made of a friction-resistant PA66 material.
The working principle of the handrail overturning limiting mechanism is as follows:
when the opening or closing of the armrest assembly is required to be realized, the armrest assembly is rotated, at this time, the armrest rotating fixed shaft 5 is taken as a rotating center, the armrest rotating fixed shaft 5 rotates along the first through hole 21, the second through hole 31 and the third through hole 61, and the armrest rotating shaft 4 slides along the first fan-shaped waist hole 20, the second fan-shaped waist hole 30 and the third fan-shaped waist hole 60, so that the opening or closing of the armrest assembly is realized.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
