Description

A kind of split pin withdrawing device

[technical field]

The utility model relates to a kind of instrument, especially relates to a kind of split pin withdrawing device.

[background technology]

At present, wedging shape (fingertip) contact: described in conjunction with Fig. 1, it is to overlap Upper gasket (5) on the conductive seat then at the two ends of stud (4) respectively and pinned by split pin (3) by with stud (4) sleeve spring (2) fingertip (1) being fitted in; Along with life cycle increases, the split pin (3) on the stud (4) also exposing to the weather constantly aging down, the split pin that has (3) in less than year with regard to seriously corroded.And when changing, get to come out in perforation because of the split pin rust, can not in time change and the hidden danger that causes the accident.Use instrument such as common pliers to be difficult to it is extracted, get and use fully about 10～25 minutes in order to extract the dead split pin of a rust sometimes, consume the time of maintenance greatly, prolonged electric power feeding time.

[summary of the invention]

In order to overcome the deficiency in the background technology, the purpose of this utility model provides a kind of split pin withdrawing device, and described split pin withdrawing device has utilized the principle of lever, can take out split pin fast.

For achieving the above object, the utility model adopts following technical scheme:

A kind of split pin withdrawing device, comprise handle, rotating seat, extract handle, contact pin, card pipe, described card pipe top one side is fixedly connected on handle one side end, be provided with the stopper slot of two symmetries in card pipe bottom to end, at a side socket rotating seat of handle, the bottom of rotating seat flexibly connects the tip of " 7 " font of extracting handle and contact pin formation.

Described split pin withdrawing device, the bottom of rotating seat are flexibly connected the tip extract " 7 " font that handle and contact pin form by rivet.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

Split pin withdrawing device described in the utility model by the principle of lever, inserts contact pin in the hole of split pin afterbody,, pulls and extracts handle and just split pin can be taken out as impetus by the card pipe; The utility model is reasonable in design, and is easy and simple to handle, safe and reliable, time saving and energy saving, can take out split pin fast.

Fig. 1 is the user mode structural representation of split pin on fingertip;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is that the A of Fig. 2 is to view;

In the drawings: 1, fingertip; 2, spring; 3, split pin; 4, stud; 5, pad; 6, rotating seat; 7, handle; 8, card pipe; 9, rivet; 10, extract handle; 11, contact pin; 12, stopper slot.

[specific embodiment]

In conjunction with the accompanying drawings to the utility model further instruction; The utility model is not limited to the following examples;

2,3 split pin withdrawing devices that provide in conjunction with the accompanying drawings, comprise handle 7, rotating seat 6, extract handle 10, contact pin 11, card pipe 8, described card is managed 8 tops, one side and is fixedly connected on handle 7 one side ends, be provided with the stopper slot 12 of two symmetries in card pipe 8 bottoms to end, at a side socket rotating seat 6 of handle 7, the bottom of rotating seat 6 is flexibly connected the tip of extracting " 7 " font that handle 10 and contact pin 11 form by rivet 9.

Implement split pin withdrawing device described in the utility model, with the split pin 3 on the corresponding stud 4 of two stopper slots, 12 difference of card pipe 8, the hole of the afterbody of the contact pin 11 corresponding split pins 3 on the handle 7 wherein, press down described contact pin 11 behind the utility model and just insert in the hole of afterbody of split pin 3, pull and extract handle 10 and just split pin 3 can be taken out.

The utility model does not describe part in detail and is prior art.

The embodiment that selects for use in this article for open the purpose of this utility model currently thinks to suit, but will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the interior embodiment of this design and the utility model scope.
