Abstract

The utility model discloses a magnetic bolt which can attract scrap iron existing in engine oil or gear oil in an engine oil box or a gear oil box. In the magnetic bolt, a small magnet (1) is additionally arranged at the top end of an existing oil-discharging-hole bolt (2) of the oil box, or the top end of the existing oil-discharging-hole bolt (2) is rubbed on the magnet in a same direction, so that the existing oil-discharging-hole bolt (2) is provided with magnetism. As long as the magnetic bolt is screwed on an oil-discharging hole (4) of the oil box which is in the middle of the bottom of the oil box shell, the magnetic bolt can attract the scrap iron in the engine oil and the gear oil so as to better purify the engine oil and the gear oil.

Description

Magnetic bolt

Technical field

The top that the utility model relates to drain oil bolt, the especially bolt of a kind of engine oil tank and gear tank has had magnetic.

Background technique

Public sump, gear tank is to be made of the oil hole bolt on fuel tank shell and top, the drain oil bolt and the inner filter screen of bottom at present, the effect of drain oil bolt here only is an enclosing housing, can not remove foreign material such as iron filings in the machine oil, gear oil, iron foam.Filter screen can filter bigger iron filings, but can not prevent passing through of iron foam, makes it to enter machine oil recirculation, and the time is of a specified duration excessively, and foreign material such as the iron filings of accumulation can stop up mesh, has also influenced the recirculation of machine oil so need it is carried out the cleaning of not timing, and is cumbersome.

Summary of the invention

For overcoming the deficiency that existing drain oil bolt can not adsorb the iron filings iron foam in machine oil and the gear oil, the utility model provides a kind of Magnetic bolt, and this bolt can not only the closed fuel tank housing, can also dispose iron filings, iron foam in machine oil, the gear oil easily.

The technological scheme that its technical problem that solves the utility model adopts is:

Add on the top of original drain oil bolt and to put a fritter magnet or, to make it also to have had magnetic top unidirectional friction on magnetite of former drain oil bolt.The drain oil bolt just can adsorb the iron filings iron foam in machine oil, the gear oil fall, thereby has further purified machine oil and gear oil in the closed fuel tank housing like this.This method is also convenient and easy simultaneously.

The beneficial effects of the utility model are:

In the closed fuel tank housing, further removed the iron filings iron foam that brings because of motor or gear wear that is present in the machine oil, gear oil again, effectively purified machine oil, gear oil, be beneficial to the recirculation of machine oil, gear oil.The bolt top only adds has put a fritter magnet, simple in structure, easy to clean, when changing waste oil it is wiped examination and gets final product.

Fig. 2 is a plan view of the present utility model;

Fig. 3 is a fuel tank shell structural representation of the present utility model.

Embodiment

In Fig. 3, the drain oil 4 that is positioned at 3 centres, fuel tank shell bottom is put on the top of Magnetic bolt 5, upwards screwed then, make it the closed tank housing, then being positioned at adding of drain oil bolt 2 tops puts magnet 1, will adsorb iron filings, iron foam in machine oil and the gear oil.

Claims

1. a Magnetic bolt is made of magnet and bolt two-part, it is characterized in that, adds on the top of original drain oil bolt to have put a fritter magnet and maybe top unidirectional friction on magnetite of this bolt is made it to have had magnetic.

2. Magnetic bolt according to claim 1 is characterized in that, this bolt is the drain oil bolt of fuel tank.

3. Magnetic bolt according to claim 1 is characterized in that, adds on the top of drain oil bolt to have put a fritter magnet, or through unidirectional friction on magnetite, makes it to have had magnetic.

4. Magnetic bolt according to claim 1 is characterized in that, is used for adsorbing the iron filings iron foam in sump and gear tank machine oil and the gear oil.
