Description
Technical field
The utility model relates to automobile link technical field, is specifically related to a kind of multi-functional connecting bolt.
Background technique
Bolt is one of modal fastening piece, and it is made up of head and screw rod.Screw rod is cylindric, on can to arrange in pairs or groups with nut with outside thread and use.Screw bolt and nut uses jointly, can connect and fix two parts with through hole.And traditional bolt function is single, intensity is not good, and the life-span is short, and screw rod resistance to shock is poor, easily loosens, and after long-time use, bolt is easily fixed together with nut because getting rusty, and it is convenient not to dismantle.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of reasonable in design, intensity are good, the life-span is long, the multi-functional connecting bolt of good anti-vibration, convenient disassembly.
For achieving the above object, the utility model provides following technological scheme: a kind of multi-functional connecting bolt, comprise bolt head and bolt cylinder, described bolt cylinder comprises column body and lower prop, described bolt head is arranged at the upper end of described column body, connecting screw rod is provided with between column body and lower prop, the two ends of described connecting screw rod are threaded with described column body and described lower prop respectively, described lower prop lower end is thread section, described thread section is provided with the lubrication groove with lower prop centerline parallel, described bolt head is symmetrically arranged with two threading holes, a locking rope is respectively arranged with in two described threading holes.
By adopting technique scheme, make first column body, lower prop and connecting screw rod to be dismantled when bolt is fixed together with existing nut because getting rusty, now can by bolted existing two parts separately, then in lubrication groove, add lubricant oil, thus the lower prop of bolt and existing nut dismounting are opened; The design of threading hole and locking rope, can by adjacent bolt-locking, improves the resistance to shock of bolt, not easily loosens, reasonable in design, intensity are good, the life-span is long, good anti-vibration.
The utility model is set to further: described bolt head lower end surface is provided with article putting groove, is embedded with magnet in described article putting groove.By this setting, magnet can make bolt head hold irony parts, makes bolt fixing reliable, not easily loosens.
The utility model is also set to further: in described column body, annular is provided with annular slot, is embedded with sealing rubber ring in described upper annular slot; On described lower prop, annular is provided with lower annular slot, is embedded with lower seal rubber ring in described lower annular slot.By this setting, upper sealing rubber ring and lower seal rubber ring make bolt cylinder resistance to shock better.
The utility model is also set to further: be provided with the upper screwed hole mated with described connecting screw rod in the middle part of described column body lower end surface; Be provided with the lower tapped hole mated with described connecting screw rod in the middle part of described lower prop upper-end surface, described connecting screw rod upper end is threaded with upper screwed hole, and described connecting screw rod lower end is threaded with lower tapped hole.By this setting, connecting screw rod and column body and lower prop easy to connect.
The utility model is also set to further: two described threading hole center lines and column body centerline parallel.By this setting, threading hole arranges rationally, and screw retention performance is better.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is reasonable, make first column body, lower prop and connecting screw rod to be dismantled when bolt is fixed together with existing nut because getting rusty, now can by bolted existing two parts separately, then in lubrication groove, add lubricant oil, thus the lower prop of bolt and existing nut dismounting are opened; The design of threading hole and locking rope, can by adjacent bolt-locking, improves the resistance to shock of bolt, not easily loosens, intensity is good, the life-span is long, good anti-vibration.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
