Abstract
The utility model discloses a magnetic driving anti-returning lock bolt which is provided with a chamber in the center of the bottom, a through hole communicated with the chamber in the center of the bolt upper part, a symmetrical round hole outside the chamber and an external magnet inside the round hole covered with a spacer sleeve. The chamber is provided with a spacer sleeve-covered internal magnet with the same pole as the close external magnet, and a connecting rod connected with the internal magnet passes through the through hole to the bolt top to connect with the nut. The device has reliable anti-returning and locking functions. When the connecting rod is adjusted, if only the internal magnet and the external magnet are in the same line, a strong repulsion force is generated for pushing the outer part of the external magnet out of the external orifice of the round hole to act on the nut wall of the bolt with anti-returning and locking functions. When the screw is adjusted, the magnetic force disappears and the external magnet retreats into the round hole completely, and this is convenient for disassembling and assembling.
Description
Technical field the utility model relates to a kind of bolt, is that a kind of magneto drive that is used for the bridge of engine, aircraft, steel structure prevents returning loose bolt specifically.
The bolt of the present engine of background technique, aircraft, boats and ships, steel structure bolt under the situation of vibration easily returns pine, and the attendant needs running check; The measure of Wei Huing now is that bolt penetration hole is compiled on the cover cover with wire, can only prevent that like this bolt from losing, but can not solve the problem of returning pine; What have anti-ly returns loose bolt with expanding, the setscrew of its similar usefulness on the wall, and anti-to return pine effective, but unload difficulty especially, in addition with the method for gas cutting, disposable use, cost is high especially; What have injects a ring-like interference fit band with nylon, engineering plastics etc. in the screw section of bolt, this bolt is anti-, and to return loose effect fine, but loading, unloading all are difficult to, and it is narrow to adapt to cold and hot excursion, and oil resistance is poor.
The summary of the invention the purpose of this utility model is to provide a kind of magneto drive to prevent returning loose bolt, and it is convenient to dismounting, and the adaptive temperature excursion is wide, long service life.
The technical solution of the utility model is as follows:
The bottom centre of this bolt opens a cavity, and the central upper portion that communicates with cavity at bolt has through hole, and the circular hole of position symmetry is arranged in the above-mentioned cavity outside, and the outer magnet of bag separation sleeve is arranged in the circular hole; The inner magnet that the outsourcing separation sleeve is arranged in the cavity, this magnet is identical with close outer magnet magnetic pole, and the connecting rod that inner magnet connected passes above-mentioned through hole to bolt top and connects nut.
The connecting rod of above-mentioned magnet has packing ring under nut.
The outer circular hole of above-mentioned cavity is to be separated by 2 that 180 degree distribute, and in each circular hole outer magnet is arranged.
Above-mentioned inner magnet, outer magnet are that neodymium iron boron is made.
Above-mentioned inner magnet, outer magnet are made for the rare earth SmCo.
Above-mentioned inner magnet is fixedlyed connected with " fourth " font with connecting rod.
Advantage of the present utility model is: it is reliable 1, to prevent returning pine, adjusts connecting rod, as long as point-blank its mutual expelling force is big for inner magnet and outer magnet, the circular hole collar extension is exposed in the outside of outer magnet, outer magnet blocks the circular hole wall, acts on the nut wall of this bolt, makes it not return pine.2, be convenient to dismounting, adjust screw rod, moving up and down as long as inner magnet and outer magnet not point-blank its mutual expelling force weaken, rotate its mutual expelling forces disappearance of 180 degree, outer magnet is got back in the circular hole fully, easy disassembling is raised the efficiency, and reusable.3, the magnet of this device is that neodymium iron boron or rare earth SmCo are fit to high hot, high and cold, anaerobic environment, and operating temperature can be at-40 ℃--200 ℃ of .4, wrap separation sleeves and make magnetic force indiffusion, good stability.
Description of drawings Fig. 1 is the utility model overall structure generalized section.
The utility model is described in further detail below in conjunction with accompanying drawing for embodiment.
Can see structure of the present utility model by Fig. 1, the bottom centre of this bolt opens a cavity 9, and the central upper portion that communicates with cavity at bolt has through hole 4, and 180 degree of being separated by in the above-mentioned cavity outside have two circular holes 11, and the outer magnet 8 of bag separation sleeve 12 is arranged in the circular hole; The inner magnet 10 that outsourcing separation sleeve 7 is arranged in the cavity, this magnet is identical with close outer magnet magnetic pole, and magnet is that neodymium iron boron is made, and inner magnet is fixedlyed connected with " fourth " font with connecting rod, this connecting rod 6 passes above-mentioned through hole and connects nut 1 to the bolt top, and the connecting rod of magnet has packing ring 2 under nut; 3 is screw rod, and 5 is screw thread.
