Description
Technical Field
The utility model relates to a bolt technical field especially relates to an anti-oxidation bolt.
Background
Adapted for use withNutCylindrical threadedFastening is carried outAn element consisting of a head andscrew rodFastening piece (cylinder with external screw thread) composed of two parts, which is matched with nut and used for fastening and connecting two parts with through holeDetails ofIn this connection formCall bolted connection, if the nut is from the bolt unscrewing, can make these two parts separately again, so bolted connection belongs to and dismantles the connection, the extensive application of bolt is in the mechanical engineering field, some bolts are direct to be exposed in the air for a long time, along with the increase of time, the bolt easily sends out the phenomenon of rusting, the later stage bolt of not being convenient for demolish, some bolts are higher by the frequency of dismantlement and installation simultaneously, the local easy wearing and tearing with the spanner contact in the bolt, along with the aggravation of wearing and tearing, take place the slip between spanner and the bolt, be not convenient for dismantle.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the bolt corrosion and the bolt and the spanner contact department wearing and tearing that exist among the prior art make the slip between spanner and the bolt, the shortcoming of being not convenient for to dismantle, and the anti-oxidation bolt that provides.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the anti-oxidation bolt comprises a connecting column, wherein an external thread is arranged on the outer side of the connecting column, a round table is fixedly connected to the top end of the connecting column, a rectangular block is fixedly connected to the top end of the round table, the rectangular block, the round table and the connecting column are of an integrated structure, an anti-corrosion layer is coated on the surfaces of the round table and the rectangular block, an anti-oxidation layer is coated on the outer sides of the rectangular block, the round table and the connecting column, and the anti-corrosion layer on the surfaces of the round table and the.
Preferably, the rectangular sleeve is sleeved on the outer side of the rectangular block, and the rectangular sleeve and the rectangular block are in interference fit.
Preferably, a disassembly groove is formed in the top end of the circular truncated cone relative to the bottom end of the rectangular sleeve, and the cross section of the disassembly groove is triangular.
Preferably, an anti-oxidation cap is sleeved on the outer side of the rectangular sleeve, a rectangular groove is formed in the bottom end of the anti-oxidation cap, and the rectangular groove is matched with the rectangular sleeve.
Preferably, the ratio of the thickness of the anticorrosive layer to the thickness of the oxidation resistant layer is 1: 1.
the utility model provides an anti-oxidation bolt, beneficial effect lies in:
1. the utility model can avoid the rectangular sleeve from being directly exposed in the air by arranging the anti-oxidation cap;
2. by arranging the rectangular sleeve, the rectangular sleeve is taken down from the disassembling groove by using a tool after the rectangular sleeve is worn, so that the service life of the connecting column can be prolonged;
3. the utility model discloses a set up the round platform, keep apart the external screw thread part on the spliced pole with the external world, avoid air and steam to get into between spliced pole and the connecting piece from the external screw thread department.
