Abstract
The utility model discloses a disassembling device of a propeller. The disassembling device of the propeller comprises a transmission main board, a connecting bolt, a locating nut and a driving bolt, wherein the transmission main board is provided with a through hole and a threaded hole, the connecting bolt penetrates through the through hole in the transmission main board and is fixed through the locating nut, and the driving bolt is screwed into the threaded hole in the transmission main board. The disassembling device of the propeller is fixedly connected with the propeller through the connecting bolt, the driving bolt is screwed into the threaded hole in the transmission main board, one end of the driving bolt is enabled to abut against a main shaft of the propeller and the driving bolt is screwed continuously, and the propeller can break away from a ship under the thrust of the driving bolt, so that the purposes of improving the disassembling efficiency, protecting the propeller and not damaging the main shaft are achieved.
Description
Technical field
The utility model relates to a kind of screw provision for disengagement.
Background technology
At present, there is not special-purpose screw extracting tool at spitkit.Therefore, boats and ships manufacturer or repair shop use hammer to knock screw usually and dismantle this traditional mode, still, so very easily can damage screw or main shaft, and the efficient of dismounting are low.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of screw provision for disengagement simple in structure, to realize improving removal efficiency, the purpose that protection screw and main shaft are not destroyed.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of screw provision for disengagement, comprise transmission mainboard, connecting bolt, setscrew nut and drive bolt, described transmission mainboard is provided with through hole and screwed hole, described connecting bolt passes the through hole on the described transmission mainboard, and fix by described setscrew nut, described driving bolt is screwed in the screwed hole of tightly going on the described transmission mainboard.
Preferably, the through hole on the described transmission mainboard is shaped as ellipse.
Preferably, be provided with pad between described setscrew nut and the described transmission mainboard, described pad is set on the described connecting bolt.
Pass through technique scheme, the screw provision for disengagement that the utility model provides, by connecting bolt this device is fixedlyed connected with screw, screw in the screwed hole that enters on the transmission mainboard driving bolt, make an end of driving bolt withstand the main shaft of screw and continue to screw screw disengaging boats and ships under the thrust that drives bolt; This device cost of manufacture is lower, and is convenient and reliable during use, just need not to beat and screw can be removed, and not only protected screw and main shaft, and improved removal efficiency.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
Fig. 1 is the structural representation of the disclosed a kind of screw provision for disengagement of the utility model embodiment;
Fig. 2 is the structural representation of the disclosed transmission mainboard of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of screw provision for disengagement (referring to Fig. 1 and 2), comprise transmission mainboard 11, connecting bolt 12, setscrew nut 13 and drive bolt 14, transmission mainboard 11 is provided with through hole 15 and screwed hole 16, connecting bolt 12 passes the through hole 15 on the transmission mainboard 11, and fixing by setscrew nut 13, drive bolt 14 and screw in the screwed hole 16 of tightly going on the transmission mainboard 11.Through hole 15 on the transmission mainboard 11 be shaped as ellipse, be convenient to adjust the position of connecting bolt 12, to adapt to the screw of plurality of specifications.Be provided with pad 17 between setscrew nut 13 and the transmission mainboard 11, pad 17 is set on the connecting bolt 12, has prevented that the sliding gomphiasis of setscrew nut 13 from taking off.
By connecting bolt 12 this device is fixedlyed connected with screw, screw in the screwed hole 16 that enters on the transmission mainboard 11 driving bolt 14, make an end of driving bolt 14 withstand the main shaft of screw and continue to screw screw disengaging boats and ships under the thrust that drives bolt 14; This device cost of manufacture is lower, and is convenient and reliable during use, just need not to beat and screw can be removed, and not only protected screw and main shaft, and improved removal efficiency.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
