Abstract
The utility model discloses a kind of cotter pin split-pin device, including sleeve, connecting rod and drag hook, the screw rod being threadedly engaged is equipped in sleeve, the outer end of screw rod is fixedly connected with handle, the inner end of screw rod and one end of connecting rod are rotatablely connected, and the other end of connecting rod stretches out sleeve and is fixedly connected with drag hook；The drag hook can be formed with the pin hole of cotter pin to be cooperated；Cotter pin is held in the pin hole of cotter pin in use, drag hook is protruded into, then rotational handle moves screw rod to outside sleeve, to drive connecting rod to be displaced outwardly, then make drag hook that cotter pin be pulled to be detached from from the component of installation, achieve the purpose that disassembly, it is high-efficient, easy to use；Kato plate is withstood on the component that cotter pin is installed, can prevent sleeve from lead screw being followed to rotate, improves disassembly effect.
Description
Technical field
The utility model relates to electric power overhaul equipment technical field, specifically a kind of cotter pin split-pin device.
Background technique
Cotter pin is a kind of common fixing piece, is had a wide range of application, easy for installation.Currently, the disassembly of cotter pin all makes
The case where with pliers, first mediating portion is opened, then drawn in circle side with pliers, encountering cotter pin corrosion, can not be successfully and remove,
Working efficiency is very low.
Utility model content
The purpose of this utility model is to provide a kind of cotter pin split-pin device, the split-pin device can rapidly to cotter pin into
Row disassembly, it is high-efficient, easy to use.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of cotter pin split-pin device, including sleeve, connecting rod and drag hook, sleeve is interior to be equipped with the screw rod being threadedly engaged, screw rod
Outer end is fixedly connected with handle, and the inner end of screw rod and one end of connecting rod are rotatablely connected, and the other end of connecting rod stretches out sleeve and drag hook
It is fixedly connected；The drag hook can be formed with the pin hole of cotter pin to be cooperated.
Further, one end of the sleeve is equipped with the Kato plate of arc, and Kato plate is located at the drag hook side of sleeve.
The utility model has the beneficial effects that holding cotter pin in the pin hole of cotter pin in use, drag hook is protruded into, then
Rotational handle moves screw rod to outside sleeve, so that connecting rod be driven to be displaced outwardly, drag hook is then made to pull cotter pin from installation
It is detached from component, achievees the purpose that disassembly, it is high-efficient, easy to use；Kato plate is withstood on the component that cotter pin is installed, it can
To prevent sleeve from lead screw being followed to rotate, disassembly effect is improved.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model provides a kind of cotter pin split-pin device, including sleeve 1, connecting rod 2 and drag hook 3, sleeve 1
Interior equipped with the screw rod 4 being threadedly engaged, the outer end of screw rod 4 is fixedly connected with handle 5, and the inner end of screw rod 4 and one end of connecting rod 2 rotate
Connection, the other end of connecting rod 2 stretch out sleeve 1 and are fixedly connected with drag hook 3；The drag hook 3 can be formed with the pin hole 7a of cotter pin 7
Cooperation.
Preferably, one end of sleeve 1 is equipped with the Kato plate 8 of arc, Kato plate 8 is located at the drag hook side of sleeve.
Hold cotter pin in use, drag hook 3 is protruded into the pin hole 7a of cotter pin 7, then rotational handle 5 make screw rod 4 to
It is mobile outside sleeve, so that connecting rod 2 be driven to be displaced outwardly, then makes drag hook 3 that cotter pin 7 be pulled to be detached from from the component 9 of installation, reach
It is high-efficient, easy to use to the purpose of disassembly；When disassembly, Kato plate 8 is withstood on the component 9 that cotter pin is installed, it can be to prevent
Only sleeve follows lead screw to rotate, and improves disassembly effect.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation；Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore, all contents without departing from technical solutions of the utility model, according to the utility model
Technical spirit any simple modification, equivalent replacement, equivalence changes and modification made to the above embodiment are still fallen within practical
In the range of the protection of new technique scheme.
