Description

A kind of quick erecting by overhang

Technical field

The utility model belongs to the mechanical part technical field, is specially a kind of quick erecting by overhang.

Background technique

Common erecting by overhang is that hook is set on hanging object, during use, the hook of hook on hanging object of erecting by overhang is hung in, though it is simple in structure, but need manually-operable, use inconvenience, can not realize hanging up fast and throwing off, and externally the active force lower draw-bar breaks away from easily, has potential safety hazard.Also by the erecting by overhang that adopts other structure to form, the structure more complicated is used inconvenient usually.

The model utility content

At the above-mentioned problems in the prior art, the purpose of this utility model is to design provides a kind of technological scheme that can finish the quick erecting by overhang that suspension ring hang up fast, throw off, and it is simple in structure, and is safe and convenient to use.

Described a kind of quick erecting by overhang, it is characterized in that protecgulum, bonnet, two bearing pin riveted joints cooperated about intermediate passed through, protecgulum, the grab that sways is set on the bearing pin between the intermediate, the inboard connection of grab is provided with round bar, round bar is pressed to touch with the pressure spring elasticity in the right groove that is arranged on intermediate and is cooperated, protecgulum, the clamp that sways is set on the bearing pin between the intermediate, the clamp upper end is pressed to touch with the spring in the left groove that is arranged on intermediate and is cooperated, suspension ring and grab are pressed to touch to rotate and are fastened grab, the grab end face of clamp by being provided with on it, clamp end face clamping locking cooperates.

Described a kind of quick erecting by overhang is characterized in that the riveted joint of protecgulum bottom is provided with bearing pin, and the controlling rod that sways is set on the bearing pin, and the inner end of controlling rod is pressed to touch with the clamp lower end and cooperated.

Described a kind of quick erecting by overhang is characterized in that on the described grab opening being set, and suspension ring are fastened by this opening and grab.

Above-mentioned a kind of quick erecting by overhang, when suspension ring are pressed downwardly onto grab, grab sways, and when the grab end face forwarded the clamp end face to, the clamp end face blocked the grab end face, and at this moment suspension ring are not lockable and can throw off; During disengagement, need the pulling controlling rod, the inner end of controlling rod promotes clamp and overcomes spring force and rotate, and makes clamp face opening grab end face, and the round bar of grab is promoted by spring, grab rotate opening upwards and suspension ring throw off, promptly finished suspension ring and hung up fast and throw off.This erecting by overhang is simple in structure, and is safe in utilization, significantly improved working efficiency, and installs, dismantles, keeps in repair all very convenient.

Embodiment

The utility model is described in further detail below in conjunction with Figure of description:

As shown in the figure, protecgulum 1a, bonnet 1, intermediate 2 is by bearing pin 9, bearing pin 13 riveted joints cooperate, protecgulum 1a, the grab 5 that sways is set on the bearing pin 13 between the intermediate 2,5 inboard connections of grab are provided with round bar 5b, round bar 5b presses to touch with pressure spring 4 elasticity in the right groove 3 that is arranged on intermediate 2 and cooperates, protecgulum 1a, the clamp 10 that sways is set on the bearing pin 9 between the intermediate 2, clamp 10 upper ends are pressed to touch with spring 8 elasticity in the left groove 7 that is arranged on intermediate 2 and are cooperated, suspension ring 6 are pressed to touch to rotate with grab 5 and are fastened grab 5, the grab end face 5a of clamp 10 by being provided with on it, clamp end face 10a clamping locking cooperates.On the described grab 5 opening is set, suspension ring 6 are fastened by this opening and grab 5.The riveted joint of protecgulum 1a bottom is provided with bearing pin 12, and the controlling rod 11 that sways is set on the bearing pin 12, and the inner end of controlling rod 11 is pressed to touch with clamp 10 lower ends and cooperated.

When suspension ring 6 are pressed downwardly onto grab 5, grab 5 rotates around bearing pin 13, and suspension ring 6 snap in the opening of grab 5, grab 5 continues to rotate around bearing pin 13, when grab end face 5a forwarded clamp end face 10a to, clamp end face 10a blocked grab end face 5a, and suspension ring 6 are not lockable and can throw off; During disengagement, need pulling controlling rod 11, the inner end promotion clamp 10 of controlling rod 11 overcomes the elastic force of spring 8 and rotates around bearing pin 9, make clamp end face 10a throw off grab end face 5a, the round bar 5b of grab 5 is compressed spring 4 and promotes to slide in right groove 3, rotate around bearing pin 13 thereby drive grab 5, grab 5 turn to opening when making progress with suspension ring 6 disengagements, promptly finished suspension ring 6 and hung up fast and throw off.This erecting by overhang can be widely used in industry-by-industry, hangs up fast and throws off as the mowing dish that can be used for grass-cutting vehicle, and is safe in utilization, significantly improved working efficiency, and install, dismounting, maintenance be all very convenient.
