Description
Technical field
This utility model relates to a kind of connection securing member, particularly relates to a kind of reinforced fixing antirust bolt.
Background technology
Bolt is a kind of by a head and screw rod class securing member dimerous, needs and nut screw connection, is used for
It is fastenedly connected two parts with through hole.During retaining element, general bolt strained point all exists
On the screw rod of bolt, therefore it sometimes appear that the tension meeting twisted when installing is along the surface on side, hole on bad part,
Crossing pine the most again can not be firm, and the bolt having is installed on outdoor, exposes to the sun and rain and the change of air humidity
Will cause getting rusty on the screw rod of bolt, shorten the service life of whole bolt.
Utility model content
This utility model embodiment technical problem to be solved is, for during retaining element,
General bolt strained point is all on the screw rod of bolt, therefore it sometimes appear that the tension twisted when installing can be along bad
The surface on side, hole on part, crossing pine the most again can not be firm, and the bolt having is installed on outdoor, Exposure to Sunlight rain
Drench and the change of air humidity all can cause getting rusty on the screw rod of bolt, shorten the use longevity of whole bolt
The problem of life, it is proposed that a kind of reinforced fixing antirust bolt.
In order to solve above-mentioned technical problem, this utility model embodiment provides a kind of reinforced fixing antirust spiral shell
Bolt, this reinforced fixing antirust bolt includes: bolt head, its center offers groove, in groove
The heart is provided with the first rotation process portion, and the edge of groove offers oiling groove, and bolt head offers four
About the symmetrically arranged screw of groove；Threaded rod, is connected away from one end of groove is fixing with bolt head, screw thread
Being provided with external screw thread on the outer surface of bar, oiling groove is close to the outer surface of threaded rod towards one end of threaded rod.
Wherein, the cross section of bolt head is square.
Wherein, bolt head thickness 1cm.
Wherein, oiling groove has two, and two oiling grooves are symmetrical arranged about the first rotation process portion.
Wherein, threaded rod is away from being provided with the second rotation process portion on one end of bolt head.
Implement this utility model embodiment, have the advantages that of the present utility model reinforced fixing anti-
Rust bolt by increasing screw on bolt head, and then by increase screw connect increase part and part,
Stress point between part and bolt, makes whole bolt more firm during fixing, and sets up note
Oil groove, is avoided that bolt is damaged because getting rusty and brief service life.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, comes for those of ordinary skill in the art
Say, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the reinforced fixing antirust bolt that this utility model provides；
Fig. 2 is the plan structure schematic diagram of bolt head in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
This utility model provides a kind of reinforced fixing antirust bolt, and referring to Fig. 1 and Fig. 2, Fig. 1 is
The structural representation of the reinforced fixing antirust bolt that this utility model provides；Fig. 2 is bolt head in Fig. 1
Plan structure schematic diagram.This reinforced fixing antirust bolt includes that bolt head 10, groove 11, first rotate behaviour
Make portion 12, oiling groove 13, screw 14, threaded rod 20, external screw thread 21 and the second rotation process portion 22.
The center of bolt head 10 offers groove 11, groove 11 be provided centrally with the first rotation process
Portion 12.The edge of groove 11 offers two about the first symmetrically arranged oiling in rotation process portion 12 groove
13.Four are offered about the symmetrically arranged screw of groove 11 14 on bolt head 10.Bolt head 10 transversal
Face is square, the thick 1cm of bolt head 10.
Threaded rod 20 and bolt head 10 are connected away from one end of groove 11 is fixing, the outer surface of threaded rod 20
On be provided with external screw thread 21.Oiling groove 13 is close to the outer surface of threaded rod 20 towards one end of threaded rod 20.
Threaded rod 20 is provided with the second rotation process portion 22 on the one end away from bolt head 10.
When using this reinforced fixing antirust bolt to fix two parts, threaded rod 20 is penetrated two parts
Hole in, rotated thus screwing bolts in the first rotation process portion 12 by instrument, then at four screws
Put in 14 slightly shorter than the screw of threaded rod 20 and tighten.Threaded rod 20 passes through away from one end of bolt head 10
Nut is fixed.After screw in having dismantled screw 14, owing to the limiting factors such as space size are inconvenient from spiral shell
When dismantling on mother, directly can be rotated in the second rotation process portion 22 by instrument, can conveniently dismantle.
After bolt uses a period of time, can directly from oiling groove 13 oiling prevent it from getting rusty.
Implement this utility model embodiment, have the advantages that of the present utility model reinforced fixing anti-
Rust bolt by increasing screw on bolt head, and then by increase screw connect increase part and part,
Stress point between part and bolt, makes whole bolt more firm during fixing, and sets up note
Oil groove, is avoided that bolt is damaged because getting rusty and brief service life.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
