Abstract
The utility model relates to a spring adjusting tool used in the power system. The spring adjusting tool comprises a fixed plate and a leading screw arranged on the fixed plate, wherein an upper clamping plate and a lower clamping plate are arranged in the upper end portion of the leading screw, a nut is arranged between the upper clamping plate and the lower clamping plate, and the upper and lower clamping plates are fixed and connected via a connecting rod. The spring adjusting tool can stretch out or draw back a spring very easily, thereby saving time and labor, and being safe and convenient in use.
Description
Technical field
The utility model relates to a kind of power equipment, is specifically related to a kind of electric power system spring adjustment means.
Background technology
The use of grid power medi-spring is very extensive, all to use spring such as primary cut-out, divide-shut brake etc., and because these equipment often damage, need often maintenance or replacing, at first spring to be pulled down, be in extended state and spring has, what have is in compressive state, has certain potential energy, does not have special-purpose instrument, install, dismantle quite difficulty of energy-stored spring, and easily hurt sb.'s feelings.
Summary of the invention
The utility model provides a kind of spring adjustment means at the problem that above-mentioned prior art spring loading and unloading are difficult for, and it makes spring easy to loading and unloading, and is time saving and energy saving, as safe as a house.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of spring adjustment means, it comprises fixed head, is arranged on the leading screw on the fixed head, and the leading screw upper end is provided with clamp and following clamp, is provided with nut between last clamp and the following clamp, and is fixedly connected by connecting rod between last clamp and the following clamp.
Described nut side is provided with rotating handles.
The utility model is equipped with leading screw at fixed head, and the leading screw upper end is provided with clamp and following clamp, is provided with nut between last clamp and the following clamp, can be by the rotation nut, the spring of adjusting between fixed head and following clamp, safe ready is time saving and energy saving.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, a kind of spring adjustment means, it comprises fixed head 1, is arranged on the leading screw 2 on the fixed head 1, leading screw 2 upper ends are provided with clamp 3 and following clamp 4, be provided with nut 5 between last clamp 3 and the following clamp 4, nut 5 sides are provided with rotating handles 6, and are fixedly connected by connecting rod 7 between last clamp 3 and the following clamp 4.
When the utility model uses, earlier leading screw 2 is passed from spring 8 inboards, clamp 4, nut 5 and last clamp 3 down are installed then, and last clamp 3 is fixedlyed connected by connecting rod 7 with following clamp 4, and spring 8 two ends are separately fixed on fixed head 1 and the following clamp 4, as required, rotation nut 5 if will compress spring 8, is rotated down nut 5, depress clamp 4 downwards, make it to the lower compression spring; If want extension spring 8, nut 5 is rotated up, upwards push to clamp 3, clamp 4 moves up under driving, thus extension spring.The utility model can be easy to the spring compression or stretch, and is time saving and energy saving, safe and convenient to use.
