The utility model discloses a reach above-mentioned purpose, the technical scheme of adoption as follows:

the utility model provides a can adsorb screw for car of iron fillings, includes screw head and screw rod, the free tip of screw rod seted up with the coaxial blind hole of screw rod, be equipped with the magnet in the blind hole, the magnet is close to the terminal surface of blind hole opening part with the blind hole inner wall forms the cavity that holds iron fillings.

Preferably, an annular groove is circumferentially formed in the inner wall of the opening of the blind hole, and a limiting part for fixing the magnet is arranged in the groove.

Preferably, the limiting member is a shaft snap ring, and the inner diameter of the limiting member is smaller than the shaft diameter of the magnet.

Preferably, the magnet is riveted to the screw.

Preferably, a metal adhesive is filled between one end of the magnet inserted into the blind hole and the screw.

Preferably, the blind hole is cylindrical.

Preferably, the magnet is a permanent magnet capable of generating a strong magnetic field.

Preferably, the magnet is threadedly engaged with the blind bore.

The beneficial effects of the utility model are embodied in:

ability adsorption iron fillings screw for car, in the blind hole of screw rod was located to the magnet, can easily adsorb iron fillings in the engine to iron fillings are stored in the cavity that magnet and blind hole inner wall formed, swiftly just clear up the iron fillings that the engine during operation produced effectively, have avoided remaining the secondary wear that iron fillings caused to the engine, have improved the lubrication action of machine oil, have prolonged the maintenance cycle of engine, thereby have improved the life of engine effectively.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

Example 1

As shown in fig. 1-2, the present embodiment provides a screw for an automobile capable of adsorbing iron filings, which includes a screw head 1 and a screw rod 2 provided with an external thread. The blind hole 21 has been seted up to the free tip of screw rod 2, and the blind hole 21 is the columnar hole and sets up with screw rod 2 is coaxial to guarantee that the thickness of screw rod 2 is even, make it have higher mechanical strength.

The blind hole 21 is internally riveted with a magnet 3 which is used for adsorbing iron chips and has the shape matched with the size of the blind hole 21. In order to enhance the stability of the connection between the magnet 3 and the screw rod 2, a metal adhesive 4 is filled between one end of the magnet 3 inserted into the blind hole 21 and the screw rod 2. Of course, the connection mode of the magnet 3 and the blind hole 21 is not limited thereto, and an external thread may be disposed on the magnet 3, an internal thread is disposed in the blind hole 21, the magnet 3 and the blind hole 21 are connected by a thread, and the connection mode is only a connection mode capable of effectively fixing the magnet 3 in the blind hole 21. Furthermore, an annular groove 5 is circumferentially arranged on the inner wall of the opening of the blind hole 21, a limiting part 6 for axially clamping the magnet 3 is arranged in the groove 5, and preferably, the limiting part 6 is a shaft snap ring, and the inner diameter of the shaft snap ring is smaller than the shaft diameter of the magnet 3. In order to improve the adsorption efficiency and the adsorption time, the magnet 3 is preferably a permanent magnet having a strong magnetic field.

The magnet 3 is close to the terminal surface of blind hole 21 opening part and forms the cavity 7 that holds iron fillings with the 21 inner walls of blind hole, provides accommodation space for a large amount of iron fillings to make the screw can work for a long time, need not frequently dismantle the screw.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
