In order to achieve the above purpose, the knob designed by the utility model comprises a knob body, a ferromagnetic base matched with the knob body for use is arranged below the knob body, a thread groove is arranged on the ferromagnetic base, the knob body comprises a first section part, a second section part and a third section part which are integrally formed, the first section part, the second section part and the third section part are all cylinders, the diameter of the first section part is larger than that of the second section part, the diameter of the second section part is larger than that of the third section part, the second section part is rotatably sleeved with a first sleeve, an external thread of the third section part is connected with a second sleeve, two symmetrically arranged powerful magnetic blocks are embedded in the first sleeve, two symmetrically arranged iron blocks are embedded on the second sleeve, each iron block is opposite to one powerful magnetic block, the iron blocks run through the upper end face and the lower end face of the second sleeve, the lower end of the powerful magnetic block is in contact with the iron block, the upper end of the powerful magnetic block is away from the upper end face of the first sleeve, a mounting groove is formed in the middle of the knob body, a first positioning strip is arranged on the first sleeve, a second positioning strip opposite to the first positioning strip is arranged on the second sleeve, when the first sleeve is rotated to enable the first positioning strip to be opposite to the second positioning strip, the powerful magnetic block is opposite to the iron block, and the powerful magnetic block and the iron block are attracted under the action of magnetic force.

The powerful magnetic block and the iron block are both cylindrical in structure.

The side surface of the first section part of the knob body is provided with anti-skid stripes.

And a switch indication strip is arranged on the upper surface of the knob body.

The utility model discloses the knob that obtains, its technical effect is through setting up powerful magnetic path and iron plate on the knob body, when not using, rotate powerful magnetic path and iron plate cooperation, make the iron plate have magnetism, the iron plate again with the cooperation of ferromagnetic base, because ferromagnetic base is fixed, can adsorb the knob body and lock to ferromagnetic base under the effect of magnetic force on, because children's strength is limited, under the magnetic force of powerful magnetic path, children do not move the knob body, the security that the knob used has been improved.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1:

as shown in fig. 1-10, the knob provided in this embodiment includes a knob body 1, a ferromagnetic base 2 disposed below the knob body 1 and used in cooperation with the knob body 1, a thread groove 15 disposed on the ferromagnetic base 2, the knob body 1 includes a first section 3, a second section 4 and a third section 5 which are integrally formed, the first section 3, the second section 4 and the third section 5 are all cylindrical, the first section 3 has a diameter larger than that of the second section 4, the second section 4 has a diameter larger than that of the third section 5, a first sleeve 6 is rotatably sleeved outside the second section 4, a second sleeve 7 is connected to an external thread of the third section 5, two symmetrically disposed powerful magnetic blocks 8 are embedded in the first sleeve 6, two symmetrically disposed iron blocks 9 are embedded in the second sleeve 7, each iron block 9 is opposite to a strong magnetic block 8, the iron blocks 9 penetrate through the upper end face and the lower end face of the second sleeve pipe 7, the lower ends of the strong magnetic blocks 8 are in contact with the iron blocks 9, the upper ends of the strong magnetic blocks 8 are spaced from the upper end face of the first sleeve pipe 6, an installation groove 10 is formed in the middle of the knob body 1, a first positioning strip 11 is arranged on the first sleeve pipe 6, and a second positioning strip 12 opposite to the first positioning strip 11 is arranged on the second sleeve pipe 7.

The powerful magnetic block 8 and the iron block 9 are both cylindrical.

The side surface of the first section 3 of the knob body 1 is provided with an anti-slip stripe 13.

A switch indication strip 14 is arranged on the upper surface of the knob body 1.

When the knob is used specifically, the ferromagnetic base 2 is fixed on a gas stove through the threaded groove 15, then the knob is fixed above the ferromagnetic base 2 through the matching of the mounting groove 10 and a rotating rod of the gas stove, the lower end face of the second sleeve 7 is contacted with the upper end face of the ferromagnetic base 2, the powerful magnetic block 8 is contacted with the iron block 9 in an unused state, the iron block 9 generates magnetic force with the ferromagnetic base 2 after being magnetized, so that the second sleeve 7 is attracted with the ferromagnetic base 2, the second sleeve 7 is spirally fixed on the knob body 1, and the knob body 1 is not easy to rotate under the action of the magnetic force, particularly, small children have limited strength and cannot rotate; when needs are igniteed, rotate first sleeve 6, make powerful magnetic path 8 and iron plate 9 take place the dislocation, iron plate 9 does not have after the magnetism just can not produce magnetic force effect with between the ferromagnetic base 2, and knob body 1 can rotate and use with normally striking sparks.

This embodiment is through setting up powerful magnetic path 8 and iron plate 9 on knob body 1, when not using, make first locating bar 11 aim at second locating bar 12 through rotating first sleeve 6, make powerful magnetic path 8 also aim at iron plate 9, powerful magnetic path 8 and iron plate 9 cooperation, make iron plate 9 have magnetism, iron plate 9 cooperates with ferromagnetic base 2 again, because ferromagnetic base 2 is fixed, can adsorb locking to ferromagnetic base 2 with knob body 1 under the effect of magnetic force on, because children's strength is limited, under powerful magnetic path 8's magnetic force, children do not move knob body 1, the security that the knob used has been improved.
