Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides an embodiment: stand wear and tear long-life screw, including screw rod 1, screw rod 1's top fixedly connected with block 5, the main effect of block 5 is the effect that sets up mounting groove 9, the top middle part of block 5 is provided with mounting groove 9, the specific shape of mounting groove 9 is cross shape, usable cross screwdriver aims at mounting groove 9 and rotates, can install screw rod 1 or carry out the effect of dismantling, the top periphery of block 5 is provided with circular spout 8, a role for placing protective cover 6, the lateral wall of circular spout 8 is provided with draw-in groove 10, draw-in groove 10 and circular spout 8 communicate each other, 8 inside radius sizes of circular spout will be bigger than the bottom radius of protective cover 6, guarantee 4 mobilizable spaces of fastener, inner wall sliding connection of circular spout 8 has protective cover 6, avoid external dust or steam and other debris to push up inside mounting groove 9 during protective cover 6's primary action, the rusty condition in less later stage takes place, guarantee the normal dismantlement in later stage, protective cover 6 lateral wall fixedly connected with two calorie of card strip 11 of fixedly connected with of card strip 11, card strip 11 possesses certain elastic effect, card strip 11's outside bottom fixedly connected with protective cover 11 has the card strip and the hexagonal wrench is the effect again when the card 6 and the card post is realized the same material of the card 6 and the hexagonal fastener and the effect of the card when the card is taken place the card 6 and the effect of the card 6 and the hexagonal fastener and the card is realized the card at the same material of the top of the card 6 and the hexagonal bolt.
Fastener 4 blocks mutually with draw-in groove 10, the realization is to the fixed action of protective cover 6, the bottom of fastener 4 is the inclined plane and handles, make things convenient for fastener 4 better to get into the inside of circular spout 8, the bottom fixedly connected with screwhead 2 of screw pole 1, the surface of screw pole 1 is provided with thread groove 3, make the inside of thread groove 3 precession treating fixed object through the rotation of screwhead 2, thereby realize carrying out the effect of installation fixed to the screw, two draw-in grooves 10 are the symmetry setting along the axis of protective cover 6, two card strips 11 are the symmetry setting along the axis department of protective cover 6, can be accurate with the card of fastener 4 accuracy in going into draw-in groove 10, the material of screw pole 1 comprises alloy steel, alloy steel mainly comprises the material except carbon and iron with the alloy element, like copper, manganese, aluminium, titanium, tombarthite and so on material. This kind of steel has very high intensity, and have good anticorrosion, resistant high low temperature, wear-resisting and non-magnetic property, improve screw rod 1's life, protective cover 6 and screw rod 1's the even coating of surface have corrosion resistant coating, specifically scribble the copper oxide coating on its surface, strengthen its corrosion resistance, avoid screw rod 1 to take place rusty condition and take place, mounting groove 9 is cross shape, can arrange cross screwdriver or a word screwdriver and aim at mounting groove 9 and rotate, the effect of dismantling screw rod 1.
The working principle is as follows: when specifically using this device, can directly utilize the cross screwdriver to aim at mounting groove 9 and rotate, can need treating the position of fastening with screw rod 1 precession, this moment, insert protective cover 6 in circular spout 8, because card strip 11 makes for the elastic material, when fastener 4 contacts with circular spout 8, elastic deformation can take place, and finally lead to fastener 4 and draw-in groove 10 to block each other and, so realize protective cover 6's fixed effect, thereby make mounting groove 9 inside avoid the dust to push and rusty condition takes place, guarantee the normal dismantlement in later stage, when the later stage need tear the screw open, through pressing fastener 4 to the inboard, make fastener 4 break away from draw-in groove 10, upwards take out protective cover 6 this moment, utilize the cross screwdriver to aim at mounting groove 9 and accomplish the dismantlement, if mounting groove 9 takes place wearing and tearing, when protective cover 6 reinstallates, utilize spanner or other instruments to block hexagonal card post 7 and rotate, the effect that can dismantle the screw equally, the modern design, therefore, the clothes hanger is strong in practicability, and convenient for people to use.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
