Description
Technical field
Technical field of fastening is the utility model is related to, more particularly to a kind of bolt assembly.
Background technology
Bolt is widely used as a kind of common fastener in mechanical field.When more severe at some
Under environmental condition, such as moist environment, when even outdoor, connection member bolt is easy to rust.Therefore, on the one hand
The damage of connected key, the dismounting being also unfavorable in addition between part can be caused.
At present, for the relatively good solution of this defect also neither one.Generally use is tolled breakdown or let matters drift not
Give the mode comprehended.
Utility model content
The purpose of this utility model provides a kind of bolt assembly, and the bolt for making to get rusty easily disassembles under workpiece.
To solve the problems, such as that prior art is present, the utility model provides a kind of bolt assembly, and the bolt assembly includes：Spiral shell
Bolt main body and structural reinforcement member, the structural reinforcement member are detachably connected with the bolt body；The bolt body bag
Nut and screw rod are included, the structural reinforcement member is out of the insertion of nut top screw rod；The end of the screw rod is provided with centre bore, institute
Bottom of the centre bore along screw rod is stated to top to extend；It is symmetrical recessed that at least two are provided with along the centre bore to surrounding
Groove, the groove are radiated to the top of external thread of screw, the length of direction extension of the groove along screw rod from centre bore
It is adapted with the depth of centre bore.
The technical program sets centre bore in the end of screw rod, can be from this so when bolt corrosion needs dismounting
Lubricant is injected at heart hole；And fluted in the surrounding setting of centre bore, groove is radially extended to the top of external thread of screw
End, length and the depth of centre bore vertically are adapted.Lubricant is set to be exuded to via the groove up to screw flight
Place, facilitates the dismounting of bolt；In addition, when demounting bolt, when screw rod receives the extruding of power, screw rod bottom it is recessed
Groove can be gathered to central hole, so that screw rod bottom takes the lead in loosening, drive the loosening of whole screw rod, make the bolt of corrosion easy
In disassembling.
In addition, the structural reinforcement member is provided with external screw thread；The bolt body is provided with internal thread, the structural strengthening
Part connects with bolt thread.Facilitate the dismounting of structural reinforcement member.
In addition, the internal thread is the internal thread of the screwed hole extended from nut top center to inside screw, the spiral shell
Pit is connected with centre bore.When structural reinforcement member is removed, lubricant can be injected at the internal thread hole,
And screwed hole is connected with centre bore, therefore, lubricant can flow into centre bore from screwed hole, and then from the groove of centre bore
Place is oozed out, and lubricates whole screw rod.
In addition, symmetrical cross recess centered on the groove.Groove is designed as to the structure of cross recess, stud base by
During extruding, cross recess is gathered to center, and screw rod bottom loosens first, so as to be advantageous to the dismounting of corrosion bolt.
In addition, spiral oil guide groove is provided with the external screw thread of the screw rod, one end of the oil guide groove and groove
Connection, other end spiral up to bottom.Because oil guide groove and groove are attached, therefore the lubrication oozed out from groove
Agent can enter oil guide groove, and the flowing of lubricant is facilitated by oil guide groove.
In addition, the depth of the oil guide groove is less than externally threaded thread depth.The depth of oil guide groove is not deep, therefore is realizing
While Oil Guide, the intensity of screw rod ensure that.
Bolt assembly of the present utility model makes lubricant flow into screw flight by setting centre bore and groove in bottom
Place；In addition, by setting structure reinforcer, the intensity of bolt is on the one hand strengthened, on the other hand, by can be in structural strengthening
When part disassembles, lubricant is injected at nut, therefore the position of injection lubricant can be adjusted with the station of bolt, with profit
In the flowing of lubricant.So that the bolt of corrosion is easily dismantled.

Fig. 2 is a kind of a kind of schematic diagram of embodiment of the bolt of bolt assembly of the utility model；
Fig. 3 is Fig. 2 A-A sectional views；
Fig. 4 is Fig. 2 axle side schematic diagram.
In figure, bolt body 1, structural reinforcement member 2, screw rod 12, centre bore 121, groove 122；Nut 11, screwed hole 111.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1-2, the bolt assembly includes bolt body 1 and structural reinforcement member 2, structural reinforcement member 2 and bolt master
Body 1 is detachably connected, and structural reinforcement member 2 is out of, the nut top stud bolt main body 1 of bolt body 1 screw rod.
Bolt body 1 includes nut 11 and screw rod 12, and the end of screw rod 12 is provided with centre bore 121, and centre bore 121 is along spiral shell
The bottom of bar extends to top；At least two symmetrical grooves 122 are provided with along centre bore to surrounding, groove 122 is therefrom
Heart hole 121, which is set out, is radiated to the top of external thread of screw, the length and the depth phase of centre bore of direction extension of the groove along screw rod
Adapt to.Described depth is adapted, refer to groove in axial direction on depth can be with the depth substantially phase of centre bore
Together, so it is easy to oozing out for lubricant.In addition, the quantity of groove can be according to the new setting of actual conditions, and implement to exemplify
The embodiment of cross recess.
Nut 11, top can be threaded hole 111, and screwed hole 111 extends from nut top center to inside screw, with
Centre bore is connected.
Screw rod 12, outside can be to be provided with spiral oil guide groove, one end of the oil guide groove and groove at external screw thread
Connection, other end spiral up to bottom.The depth of oil guide groove is less than externally threaded thread depth., should during specific implementation
Oil guide groove can be that helix can also be the straight line extended along groove to nut direction.
Mechanism reinforcer 2, it can use and be threadedly coupled with bolt assembly 1.Can be the structure or spiral shell of screw-type
The structure of hydrant.When structural reinforcement member 2 is entered in the screw rod of bolt body 1 from the nut top of bolt body 1, to hollow spiral shell
Bolt serves good booster action.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
