Description
Technical field
The utility model relates to mechanical zero device arts, specifically a kind of antirust easy replacing rim bolt.
Background technique
Rim bolt is a kind of high-strength bolt that wheel connects with ransaxle.In the maintenance, Renewal process of wheel rim, bolt is repeatedly tightened and is unscrewed.Thus make screw bolt abrasion more serious, after the bolt head of some bolt repeatedly clamps, its corner angle can become round, even if want the bolt more renewed, this time has been difficult to turn whole bolt at tool holding bolt heads such as use spanners, simultaneously, rim bolt uses for a long time, particularly use for a long time under the larger occasion of humidity or outdoor environment, the process that bolt gets rusty is very fast, cause the dismounting of bolt difficulty and cannot reuse, and long-time use or Reusability cause thread abrasion, bolt inserts in positioning hole and can shake, fastening effect is caused to decline, there is potential safety hazard.
Model utility content
The purpose of this utility model is to provide a kind of antirust easy replacing rim bolt, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of antirust easy replacing rim bolt, comprise the first screw rod, bolt head, protective housing, screw-threaded counterbore, oil storage hole and projection, described first screw rod and bolt head are integrated, the middle part of the first screw rod is provided with screw thread, first screw rod is drilled with oil storage hole, the second screw rod is provided with outside first screw rod, step is provided with between second screw rod and the first screw rod, the both sides of step are equipped with projection, described bolt head upper surface is provided with the screw-threaded counterbore with the first screw coaxial, enters in bolt head upper cover the protective housing that plastics make.
As further program of the utility model: described oil storage hole is positioned at the crevice place of screw thread, described oil storage hole center line and the vertical and intersectant centerline of the first screw rod.
As further program of the utility model: described first screw rod is provided with spherical boss.
As further program of the utility model: the hand of spiral of described screw-threaded counterbore is contrary with the first screw flight direction.
Compared with prior art, the beneficial effects of the utility model are: the antirust easy replacing rim bolt of described one, bolt head arranges screw-threaded counterbore and protective housing, when bolt head be worn cannot by fall unscrew time, be convenient to the rim bolt more renewed, avoid rainwater to enter into screw-threaded counterbore to go simultaneously, prevent screw-threaded counterbore to get rusty damage, ledge surface is provided with projection, resistance during rollback is produced after can improving rim bolt locking, thus can useful energy prevention rim bolt produce loosen phenomenon, the full rust preventive oil of storage in oil storage hole when installing, ensure that rim bolt long antirust ability in the presence of a harsh environment, there is good loosing-proof rust-proof performance, ensure that the reliability of connection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-step, 2-first screw rod, 3-bolt head, 4-protective housing, 5-screw-threaded counterbore, the spherical boss of 6-, 7-screw thread, 8-oil storage hole, 9-are protruding, 10-second screw rod.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of antirust easy replacing rim bolt, comprise the first screw rod 2, bolt head 3, protective housing 4, screw-threaded counterbore 5, oil storage hole 8 and protruding 9, described first screw rod 2 and bolt head 3 are integrated, the middle part of the first screw rod 2 is provided with screw thread 7, first screw rod 2 is drilled with oil storage hole 8, described oil storage hole 8 is positioned at the crevice place of screw thread 7, the vertical and intersectant centerline of described oil storage hole 8 center line and the first screw rod 2, before using, first the first screw rod 2 is immersed among rust preventive oil, guarantee to fill rust preventive oil in oil storage hole 8, first screw rod 2 is provided with spherical boss 6, the second screw rod 10 is provided with outside first screw rod 2, step 1 is provided with between second screw rod 10 and the first screw rod 2, the both sides of step 1 are equipped with protruding 9, add the second screw rod 10 and need the frictional force between fastenings, add fastening effect, described bolt head 3 upper surface is provided with the screw-threaded counterbore 5 coaxial with the first screw rod 2, the hand of spiral of described screw-threaded counterbore 5 is contrary with the hand of spiral of the first screw rod 2, the protective housing 4 that plastics make is entered in bolt head 2 upper cover, after rim bolt repeatedly uses, each corner angle of bolt head 3 can be worn gradually, when rim bolt is unscrewed by needs, the holder bolt heads 3 such as spanner are used just to be difficult to unscrew rim bolt, a screw can be used this time to be screwed in screw-threaded counterbore 5 go, because the thread rotary orientation of screw-threaded counterbore 5 is contrary with the thread rotary orientation of the first screw rod 2, in the continuous rundown process of screw, then rim bolt can be unscrewed, be convenient to the replacing of rim bolt, the protective housing 4 of a plastic support is entered in bolt head 3 upper cover, bolt head 3 not only can be protected not to be subject to rainwater effect, and rainwater can be avoided to enter into screw-threaded counterbore 5 go, screw-threaded counterbore 5 is got rusty damage.
Working principle of the present utility model is: the antirust easy replacing rim bolt of described one, bolt head 3 arranges screw-threaded counterbore 5 and protective housing 4, when bolt head 3 be worn cannot by fall unscrew time, be convenient to the rim bolt more renewed, avoid rainwater to enter into screw-threaded counterbore 5 to go simultaneously, prevent screw-threaded counterbore 5 to get rusty damage, step 1 is provided with protruding 9 on the surface, resistance during rollback is produced after can improving rim bolt locking, thus can useful energy prevention rim bolt produce loosen phenomenon, the full rust preventive oil of storage in oil storage hole 8 when installing, ensure that rim bolt long antirust ability in the presence of a harsh environment, there is good loosing-proof rust-proof performance, ensure that the reliability of connection.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
