Abstract
The utility model discloses a multifunctional locking bolt used as a connecting piece on a vibrating locomotive, which is characterized in that: a repair section with hard threads is arranged at the incoming end of the screw of the bolt, and a scrap guide groove is arranged on the repair section; an interference belt for filling non-metal is arranged inside the repair section, an oil injection hole is arranged on a nut, and is communicated with an oil inlet arranged at the middle lower part of the bolt via an oil way inside the bolt. The utility model has the advantages that: the bolt does not loosen and can guard against coming off during the operation of the locomotive, and reduce the workload of maintenance staff; by means of the repair section, the distorted threads of the nut can be restored, the mounting and dismounting of the bolt is pretty easy, and the maintenance work is greatly lessened; the scrap guide groove serves the purpose of cleaning, renders the mounting and dismounting of the bolt easier; impurities can be eliminated if remounting is required, thus providing more convenience.
Description
Technical field the utility model relates to a kind of bolt, is the multi-functional anti-looseness bolt of the connection usefulness of the first-class vibration motorcycle of a kind of train bottom specifically.
The bolt that the present locomotive engine of background technique is used, worm tooth is consistent, and easily slow button is loosening in the vibration of train running, installs down because of nut, easily comes off, and the attendant needs running check.The measure of taking now is with bolt penetration hole, and on the cover cover that a plurality of bolts is through together and the top is compiled with wire, but dismounting is very inconvenient, if unloading one also will cut off cover, again compile again after loading onto, the screw thread of the nut that has simultaneously is because of vibration deformation, and dismounting is difficult.A kind of expansion anti-looseness bolt is arranged in addition, and it is similar to setscrew, and is anti-slow effective, but unloads to get off, disposable, the cost height.
The summary of the invention the purpose of this utility model is to provide a kind of multi-functional anti-looseness bolt, and it is anti-slow effective, is convenient to dismounting, and cost is lower.
The technical solution of the utility model is as follows:
This bolt has the reparation band of hard screw thread on the inlet end of screw rod, this is with out dregs guiding groove, doses nonmetallic interference band in reparation band inboard, opens an oil hole on nut, and the oil duct in this aperture bolt is communicated with the oil inlet hole of bolt middle and lower part.
Above-mentioned dregs guiding groove angle be 45 the degree.
Above-mentioned interference band it dosed nonmetal be nylon
Advantage of the present utility model is: 1, because of the interference band is arranged, nonmetal dose flexible, can be loosening in the vibration of train operation, Drop-proof reduces the work of maintenance personnel amount, 2, oil-filling mechanism, lubricate convenient disassembly arranged.3, an end of screw rod has the band of reparation, and this band is to make its worm tooth hard through high frequency hardening, and shear action is arranged, and the screw thread reparation the nut of distortion makes bolt more easy to assemble, reduces maintenance work.4, dregs guiding groove is arranged, can be with nonmetal bits and reparation that interference band in the process of twisting produces the metal fillings that produces to derive, derive greasy dirt simultaneously, play the cleaning effect, make the dismounting of bolt easier, it be more convenient to refill free from admixture.5, cost is low, is easy to promote.
Description of drawings Fig. 1 is the utility model cross-sectional view;
Fig. 2 is the utility model interference belt body generalized section
The utility model is described in further detail below in conjunction with accompanying drawing for embodiment
Can see by Fig. 1, Fig. 2, this bolt has the reparation band (7) of hard screw thread on the inlet end of screw rod (4), this is with out dregs guiding groove (8), its angle is 45 °, dose nonmetallic interference band (6) in reparation band inboard, dosed nonmetal be nylon (9), dosing on the interior screw rod of layer of interference band has three to dose groove (10), preventing to dose part turns and rotates with bolt, open an oil hole (1) on nut (2), the oil duct (3) in this aperture bolt is communicated with two oil inlet holes (5) of bolt middle and lower part.(11) for the worm tooth of interference band.
