Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
Referring to figs. 1 to Fig. 5, the utility model relates to a kind of earthed switch spring handling apparatus, comprise the location-plate bracing frame being formed by fixed head 1 and side plate 2, on described location-plate bracing frame, be installed with a nut 3, on described nut, be bolted with a screw mandrel 4, the front end of described screw mandrel is connected with one in order to be arranged on the sleeve 5 on earthed switch spring, on the rear end of described screw mandrel, be connected with one handle 6, two sides of described location-plate bracing frame are respectively equipped with one in order to catch on the movable hook 7 in earthed switch respective aperture.
Above-mentioned sleeve-shaped is a cylindrical cylindrical, and sleeve inner is stepped column structure, and this stepped column structure is corresponding with the shape of earthed switch spring pedestal.
The position that above-mentioned screw mandrel is connected with sleeve has groove, and sleeve adopts hexagon-headed bolt 13 to connect while connection with screw mandrel, and hexagon-headed bolt is just stuck in screw mandrel head recess, but not locking, while ensureing that screw mandrel rotates, the fixed effect of sleeve.
Between above-mentioned movable hook and location-plate bracing frame, be connected by bolt 8 and hex nut 9, on described movable hook, be also provided with the interior hexagonal flower shape pan head screw 10 in order to movable hook is carried out to locking positioning.
Above-mentioned location-plate bracing frame is provided with to pin the hexagon socket cap head screw 11 of nut.
The bottom of above-mentioned movable hook is provided with hexagon socket cap head screw 12.
Specific implementation process of the present utility model: comprise sleeve 5, screw mandrel 4, location-plate bracing frame 1,2, nut (making especially) 3, rocker lever 6.It is characterized in that: between the shape that special nut 3 combines with circle for rectangle and location-plate bracing frame 1,2, there is positioning action, special nut is by being converted to rectilinear motion with coordinating of screw mandrel rotatablely moving, the position that screw mandrel is connected with sleeve has groove, it is with bolts when sleeve 5 is connected with screw mandrel 4, bolt is just stuck in screw mandrel head recess, but not locking, while ensureing that screw mandrel 4 rotates, the fixed effect of sleeve 5.Sleeve 5 is the devices that directly act on spring for entangling spring, and gripper shoe 1,2 is indirectly born the elastic force effect of spring force.Other one of screw mandrel 4 has perforate, is used for inserting handle 6, like this workman's rotary screw rod 4 more easily.
