Description
Technical field
A kind of bolt is the utility model is related to, more specifically it is related to a kind of anticorrosive readily removable bolt.
Background technology
Bolt is one of most common fastener, and it is made up of head and screw rod.During existing bolt application chemical field,
It is by corrosion impact than more serious.The machine operated in the workshop of production chemical substance, chemical substance easily drop in machine
Parts and its fastener on, the extended stationary periods of chemical substance easily corrode both.Part after being corroded needs to change,
But the bolt of fastenings can be bonded in one piece with the part being corroded after being corroded, and the head of bolt can lose it is original
It shape, can be skidded using during spanner, cause bolt to be not easy to back-out, part can not be changed.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide readily removable spiral shell after a kind of be corroded
Bolt, it has the function that quick detachable after being corroded.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of anticorrosive readily removable bolt, including bolt head and screw rod, are provided with and the spiral shell between the bolt head and screw rod
The coaxial insulated column of bar, one end circumference on the insulated column close to screw rod are provided with the cage ring coaxial with the insulated column,
The cage ring is provided with the circular hole through its upper and lower end face, and the bolt head is circumferentially with symmetrical side plane.
By using above-mentioned technical proposal, the insulated column between screw rod and bolt head can be by the corruption between screw rod and bolt head
Material isolation is lost, circumferentially symmetrical two side planes of bolt head are convenient to be turned on bolt with spanner, and the setting of cage ring can be by spiral shell
Corrosive deposit and insulated column between bar and part are isolated.
Further, the bolt head is hemispherical.
By using above-mentioned technical proposal, bolt head is hemispherical, and its arc top can make chemical liquid along its surface from side
Edge slides.
Further, the insulated column side is provided with the through hole set along its cross-sectional diameter.
By using above-mentioned technical proposal, the setting of through hole, inner hexagon spanner can be made to be dismantled through through hole to bolt.
Further, the through-bore axis is parallel with the side plane.
By using above-mentioned technical proposal, the both ends of through hole are located at the lower section at arc top both ends, through hole both ends is obtained arc top
Block at both ends.
Further, the circular hole circumferential array is in the cage ring.
By using above-mentioned technical proposal, the circular hole of circumferential array, the corrosive deposit between cage ring and part has one
Determine gap, facilitate screw rod when rotating, the loosening of corrosive deposit.
In summary, the utility model has the advantages that：Insulated column between screw rod and bolt head can be by screw rod
Corrosive deposit between bolt head is isolated, and circumferentially symmetrical two side planes of bolt head are conveniently turned on bolt with spanner,
The setting of cage ring can isolate the corrosive deposit between screw rod and part and insulated column, on insulated column the setting of through hole make interior hexagonal
Spanner may pass through through hole and bolt dismantled, so that bolt of the present utility model is still easily disassembled after being corroded.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of anticorrosive readily removable bolt, as shown in figure 1, including bolt head 1, bolt head 1 is hemispherical, and its both sides is symmetrically set
There is side plane 2.The lower section of bolt head 1 is connected with insulated column 3, and a through hole is provided between the top of insulated column 3 and the bottom surface of bolt head 1
4, through hole 4 is overlapped with the cross-sectional diameter of insulated column 3, and the axis of through hole 4 is parallel with side plane, and the lower section of insulated column 3 is circumferentially with
The cage ring 5 being coaxial therewith, cage ring 5 have screw rod 7.Cage ring 5 has several circles through its upper and lower end face circumference permutation
Hole 6.
Specific work process：Two side planes 2 of bolt head 1 are blocked with spanner, bolt is screwed into part, makes cage ring 5
Bottom surface props up piece surface, completes bolt fastening.
Under chemical substance long term, bolt and part can all corrode.The meeting of cage ring 5 and piece surface after corrosion
It is bonded together to form new adhesive surface, bolt is not readily separated with part.Circular hole 6 on the bottom surface of cage ring 5 can make adhesive surface
Gap is produced, makes its structural instability, can more easily be back-outed when twisting bolt.And bolt head 1 through insulated column 3 away from parts list
Face, and the generally hemispherical of bolt head 1, both sides are cut flat with, being not easy to save bit by bit chemical substance makes it corrode and deform.Can be by pulling
Two side planes 2 that hand blocks bolt head 1 turn bolt.The top of cage ring 5 is provided with through hole 4 simultaneously, and through hole 4 is horizontal, and
First 1 outer covering is bolted, chemical substance is not entered through hole 4 make its corrosion.When removing, inner hexagon spanner can be used
Through through hole 4, and rotating inner hex wrench back-outs bolt.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, it is all in this practicality
Within new design concept, any modification, equivalent substitution and improvements made etc., protection of the present utility model should be included in
Within the scope of.
