The straight rod of root, front end setting coupler body, needs upward pulling firmly when well lid is opened, relatively elaborate, using simultaneously inconvenient.
Utility model content
The purpose of this utility model be solve current well lid hooking structure of uncapping it is simple, there are it is inconvenient to use the defects of,
A kind of well lid is provided and opens crowbar, utilizes the open manhole cover of lever principle convenient power-saving.
The utility model is achieved by the following technical solution:
I.e. a kind of well lid unlatching crowbar, it is characterised in that nunchakus body is made of inclined handle and horizontal all-or-nothing piece,
At hand portion and the rear end of all-or-nothing piece link together, and the front side bottom of all-or-nothing piece is equipped with opening hook, and the upper end of opening hook, which is equipped with, erects
Straight upward coupler body connecting rod, all-or-nothing piece are equipped with tie rod holes, and coupler body connecting rod passes through tie rod holes, and upper end connects with coupler body swing handle
It connects.
Preferred embodiment as the utility model:Tie rod holes are strip hole.Coupler body connecting rod drives opening hook can be along connecting rod
Hole moves left and right, and is conveniently adjusted position.
Preferred embodiment as the utility model:Opening hook is corner block.Well lid is equipped with and the matched unlatching of opening hook
Opening hook is directed at angle by hole, and after being inserted by open hole, arbitrary rotation angle, opening hook just cannot be extracted from open hole.
Preferred embodiment as the utility model:The downward protrusion in the rear end bottom of all-or-nothing piece.The utility model utilizes thick stick
Rod principle, the rear end protrusion of all-or-nothing piece is fulcrum,
Preferred embodiment as the utility model:Coupler body swing handle is hinged on the upper end of coupler body connecting rod by axis pin.Hook
Body swing handle when not in use, can bend the upside for being fitted in all-or-nothing piece.
Preferred embodiment as the utility model:The top of handle is equipped with the bending part less than handle angle of inclination.Hand is set
Put bending part, during use more smoothly.
The handle of the utility model can be an integral structure with all-or-nothing piece or split structure, divides when using
During body formula structure, the bottom wall of grip hole is equipped with the extension that fitting handle upwardly extends.Extension plays the role of reinforcing, prevents
The bottom wall stress excessive damage of grip hole when only using.
The hollow tube of high intensity may be used in the handle of the utility model.Mitigate weight, reduce cost.
The utility model has rational in infrastructure, flexible and convenient to use, the advantages of working efficiency is high.Using the utility model,
Well lid can be opened with convenient power-saving using lever principle, greatly reduce labour burden, improve work efficiency.
