Description

Insulating operating rod of variable rocking handle formula

Technical Field

The utility model belongs to the technical field of the live working instrument and specifically relates to an insulating bar of variable rocking handle formula is related to.

Background

In distribution network live working, a certain safety distance is required between a human body and a live body, and the operation by adopting an insulating operating rod operation method is one of the operation modes in the distribution network live working field in China. During operation, the work of tightening or loosening bolts by using an insulating operating rod is common. The traditional insulating operating rod is a single straight rod shaped like a Chinese character 'yi', and a sleeve is fixed at the top end of the rod body and used for fixing a bolt. When the bolt is screwed down or loosened, the insulating operating rod is axially rotated by the force of the wrist, so that the bolt is driven to rotate. In the rotating process, because the rotating angle of the wrist is limited, the same action needs to be repeated for many times, so the speed is slow in the rotating process, the labor is very great, and the alternate and cyclic rotation of two hands is often needed.

For example, a "join in marriage net multifunctional operation pole" that discloses on chinese patent literature, its publication No. CN208445193U, including insulating horizontal pole, spread groove and telescopic link groove have transversely been seted up respectively to the insulating horizontal pole left and right sides, telescopic link inslot chamber has inserted the telescopic link, the handle is installed on the telescopic link right side, insulating horizontal pole internally mounted has the battery, the backup pad is installed perpendicularly at insulating horizontal pole top, the light is installed in the backup pad left side, the switch is installed on the backup pad right side, the interface that charges has been seted up at insulating horizontal pole top, the connector is installed in insulating horizontal pole bottom left side. The shortcoming is that the utility model still needs to realize the purpose through rotating the wrist when screwing up or not hard up the bolt, and the structure is complicated, wastes time and energy.

SUMMERY OF THE UTILITY MODEL

The utility model relates to an overcome among the distribution network operation of prior art screw up or when becoming flexible the bolt, the problem that wastes time and energy provides the insulating bar of a variable rocking handle formula, labour saving and time saving, simple structure, convenient the accomodating.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an insulating bar of variable rocking handle formula, includes the insulator spindle, insulator spindle one end is equipped with the joint connection spare, the insulator spindle other end is equipped with the rocking handle, the rocking handle includes rocking handle pole and handle, rocking handle pole one end is rotated with the insulator spindle and is connected, rocking handle pole axis and insulator spindle between form and rotate the contained angle, the rocking handle pole rotates along rotating the contained angle, the rocking handle pole other end rotates with the handle and is connected.

The utility model is characterized in that the holding part of the insulated operating rod is provided with a rocking handle with adjustable angle, the arm of force is increased by the rocking handle, and the force for screwing or loosening the bolt is saved by utilizing the lever principle; the mode of change application of force through the setting of rocking handle will utilize wrist strength to rotate the mode of insulating action bars originally and change into and utilize arm strength to rotate the rocking handle to drive insulating action bars pivoted mode, the arm application of force is bigger, the strength is more sufficient for wrist application of force angle, makes and joins in marriage net staff's the more laborsaving operation work that carries out of faster. But the design of angle regulation rocking handle makes insulating bar be the straight-bar of "straight" style when accomodating and need increase length, adjusts the rocking handle when needs rotation operation and makes insulating bar be "Z" font, can change rapidly between different states.

Preferably, the insulating rod is fixed with a sleeve through a joint connecting piece, the sleeve is provided with a nut groove, and the axis of the nut groove is overlapped with the axis of the insulating rod.

The sleeve is used to hold the bolt and help tighten and loosen the bolt. The sleeve is coaxial with the insulating rod, so that the rotating efficiency is higher, and unnecessary waste of force is avoided.

Preferably, the sleeve is fixed to the joint connector by a fastening bolt.

The sleeve is detachably connected with the insulating rod through a fastening bolt. Different operation joints, such as nut sleeves or wire clamp clamps of different specifications, can be replaced according to actual operation conditions, and the application range of the insulating operation rod is expanded.

Preferably, both ends of the rocking handle rod are respectively connected with the insulating rod and the handle through rotating bolts.

The rocking handle can adjust the included angle between the rocking handle and the whole rod body part in the operation process, so that the size of available torque can be adjusted, and the screwing force is ensured. The setting of rotating the bolt not only can adjust the contained angle between rocking handle and the pole body, can wholly dismantle the rocking handle in addition, convenient storage.

Preferably, the connecting end of the rocking handle rod and the insulating rod is in a semi-circular arc shape, and the connecting end of the handle and the rocking handle rod is in a semi-circular arc shape.

The semicircular arc-shaped connecting end reduces the resistance generated when different sections of rod bodies collide with each other when the handle and the rocking handle rod rotate and fold, so that the folding is smoother and smoother; and the semicircular shape naturally forms a limit end, so that the folding angle is not more than 90 degrees.

Preferably, the handle is hollow.

The hollow handle effectively reduces the weight of the handle.

Preferably, the handle is made of an insulating material.

The double insulation arrangement of the insulating rod and the insulating handle further protects the safety of workers.

Preferably, the surface of the handle is provided with anti-skid lines.

The anti-slip lines increase the friction force of the handle and prevent slipping when the handle is rotated.

Therefore, the utility model discloses following beneficial effect has: (1) the rocking handle with the adjustable angle is utilized to ensure that the bolt loosening during the work of the distribution network is tightened more quickly and labor-saving; (2) the rocking handle is detachable, the angle can be adjusted, and the operation and the storage are convenient; (3) the joint can be replaced, and the application range is expanded.
