Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of automobile energy saving, and particularly relates to an oil filter element magnet anti-lost device. BACKGROUND
[0002] When the engine is running, fine iron filings can be generated by the friction of internal metal parts, and the oil circulation can take away these iron filings. However, some iron filings with a diameter less than 0.01 mm are difficult to be completely intercepted by ordinary filter elements. The magnet can use its magnetism to adsorb the iron filings in the oil, reduce the wear of internal parts caused by the iron filings returning to the engine with the oil, and prolong the service life of the engine. At the same time, the wear of the engine is reduced, the engine works more smoothly, which helps to improve the combustion efficiency of the fuel, makes the fuel burn more fully, and thus can achieve the effect of reducing fuel consumption and saving fuel, and indirectly improves the fuel economy of the vehicle.
[0003] However, when the engine is maintained, the mechanic will replace the oil filter element together with the oil, and the magnet group adsorbed on the oil filter element shell is often discarded together. In this case, there is a need for an easy-to-use object anti-toppling device. SUMMARY
[0004] The utility model discloses a kind of oil filter element magnet anti-lost devices, solve the problem that magnet group adsorbed on the oil filter element shell is prevented from being discarded during vehicle maintenance, ensure that magnet group can be continuously used, protect vehicle engine.
[0005] An oil filter element magnet anti-lost device, comprising an oil filter element (1), a magnet group (2), an ear (3), a rope (4) and a screw rod pressing piece (5).
[0006] Preferably, the oil filter element (1) has a magnet group (2) adsorbed thereon, and the magnet group (2) is provided with an ear (3).
[0007] Preferably, the ear (3) is connected with a rope (4), one end of the rope (4) is connected with the ear (3), and the other end is connected with the screw rod pressing piece (5).
[0008] Preferably, the screw rod pressing piece (5) is fixed to the engine through an engine screw rod near the oil filter element (1).
[0009] Compared with the prior art, the oil filter element has a magnet group adsorbed thereon, which is connected to the engine through a rope, effectively preventing the magnet group from being lost when the oil filter element is replaced. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 The utility model discloses an oil filter element magnet anti-lost device.
[0011] Fig. 1. Oil filter 2. Magnet group 3. Ear 4. Rope 5. Screw press. DETAILED DESCRIPTION
[0012] In order to make the technical features of the scheme more clear, the following through the specific implementation, the scheme is described.
[0013] As shown in the drawings, the oil filter is adsorbed with the magnet group, the magnet group is equipped with the ear, the ear is connected with the rope, one end of the rope is connected with the ear, the other end is connected with the screw press, the screw press is fixed on the engine through the engine screw near the oil filter.
[0014] As shown in the drawings, when the engine maintenance is carried out, the oil filter is disassembled, the magnet group is buckled off and disconnected with the oil filter, the magnet group is connected with the ear and the rope, and is fixed on the engine compartment through the screw press, at this time, the magnet group is not easy to lose.
[0015] As shown in the drawings, as described above, when the engine is maintained, the new oil filter is installed on the engine, at this time, the magnet group can be adsorbed on the new oil filter shell again, the oil filter is adsorbed with the magnet group and is not easy to lose, at the same time, through the use of the device, the magnet group can effectively prevent the falling under the condition of large amplitude bumping and vibration in the process of driving the car.
[0016] In the utility model, during the use of the device, only the magnet group needs to be adsorbed on the oil filter shell, then one end of the screw press is fixed on the engine screw near the oil filter, so that the installation is simple and easy.
[0017] The technical features not described in the utility model can be realized by or using the prior art, which will not be repeated here, of course, the above description is not a limitation of the utility model, the utility model is not limited to the above examples, the changes, modifications, additions or replacements made by the ordinary skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
