Abstract

The utility model provides a kind of anti-corrosion readily removable fastener.The utility model includes the bolt body with turret head and the nut coordinated with the bolt body, it is characterized in that:Three facades on described turret head symmetrically set a semicircular arc-shaped groove respectively, and sealing ring is provided with below described turret head, passes through one stretching, extension set with end socket of intermediate sleeve connection below described nut.The utility model is easy to assembly, reliable, does not allow or slows down dirt erosive velocity and can clear up screw thread automatically, obstruction is scraped from chip area, does not influence fastener strength and faying face frictional force, usable common tool is assembled and disassembled.

Description

A kind of readily removable fastener of anti-corrosion
Technical field:
A kind of readily removable fastener of anti-corrosion is the utility model is related to, belongs to mechanical equipment technical field.
Background technology:
Once install will be long-term use of for many equipment in industrial enterprise.Because production environment is hot and humid, also have The serious raw materials for production of corrosivity, damage and corrode to apparatus body and exposed to outer fastener, can not make into again not Become rusty steel part, all very difficult in maintenance process.
Conticaster corrodes in closing space operation, and by cooling water, high temperature slab and raw materials for production, makes the bolt of fastener Put forth effort position softening or size reduction with nut dismounting, cause common tool(Fork spanner, adjustable wrench)Torn open in bolt and nut Unload and put forth effort position skidding, then change the sleeve of small No.1 but put not enter.It can only finally be cut off with the mode of gas cutting, this process is not only Waste time and energy, the consumption energy also increases labor intensity, also with certain potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of anti-corrosion readily removable fastener for above-mentioned problem, assembling side Just, reliably, do not allow or slow down dirt erosive velocity and screw thread can be cleared up automatically, obstruction is scraped from chip area, not influenceed Fastener strength and faying face frictional force, usable common tool are assembled and disassembled.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of readily removable fastener of anti-corrosion, including the bolt body with turret head and the spiral shell with bolt body cooperation Mother, three facades on described turret head symmetrically set a semicircular arc-shaped groove, set below described turret head respectively Sealing ring is equipped with, passes through one stretching, extension set with end socket of intermediate sleeve connection below described nut.
The readily removable fastener of described anti-corrosion, the top periphery of described stretching, extension set has the edge to stretch out, described Intermediate sleeve bottom there is the edge that extends internally, described stretching, extension set and described intermediate sleeve by the edge that stretches out with The edge to extend internally is closely fastened, and is set between the described edge to stretch out and the edge that extends internally There is sealing gasket.
The readily removable fastener of described anti-corrosion, the free end of bolt body are provided with chip area.
Beneficial effect:
Plane of symmetry open semicircle arc groove of the utility model in cleaning bolt turret head.First, in order to meet processing in batching It is required that selecting appropriate drill bit holes drilled through according to bolt specification, then through hole, which is divided into two, can be made the bolt of semi-finished product Blank.Second, semicircular arc-shaped groove will not hinder common tool to use, can not conversely be torn open in bolt hexagonal focusing surface corrosion and ageing When unloading, round end chisel alignment half slot can be used to impact, or with pulling off sleeves loose unloading.
The utility model processes symmetrical two triangle chip areas in the free end of bolt body, form it into cutting edge and Space, the impurity of nut or apparatus body screwed hole is scraped during rotation, reduce rotational resistance.
The utility model under the nut side by intermediate sleeve connect one have end socket stretching, extension set can be more preferably longer prevent Protect the exposed thread of screw thread.
The utility model makes simply, and convenient disassembly, cost is low, efficiency high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the stereogram of bolt of the present utility model.
Each part is in figure:
1st, turret head, 2, bolt body, 3, nut, 4, semicircular arc-shaped groove, 5, sealing ring, 6, intermediate sleeve, 7, stretching, extension set, 8th, sealing gasket, 9, chip area, 10, connector, 11, connected piece.
Embodiment
With reference to embodiment, the utility model is furtherd elucidate, it should be understood that following embodiments are only used In explanation the utility model rather than limitation the scope of the utility model.
A kind of readily removable fastener of anti-corrosion described in the present embodiment, including the bolt body 2 with turret head 1 and with institute The nut 3 of bolt body cooperation is stated, three facades on described turret head symmetrically set a semicircular arc-shaped groove 4 respectively, Sealing ring 5 is provided with below described turret head, connecting one by intermediate sleeve 6 below described nut has stretching for end socket Exhibition set 7.
The readily removable fastener of anti-corrosion described in the present embodiment, the top periphery of described stretching, extension set have what is stretched out Edge, described intermediate sleeve bottom have the edge that extends internally, and described stretching, extension set and described intermediate sleeve are by extension The edge stretched closely is fastened with the edge to extend internally, and the described edge to stretch out and the side that extends internally Sealing gasket 8 is provided between edge.
The readily removable fastener of anti-corrosion described in the present embodiment, the free end of bolt body is provided with chip area 9.
Technological means disclosed in this patent scheme is not limited only to the technological means disclosed in above-mentioned embodiment, in addition to Formed technical scheme is combined by above technical characteristic.It should be pointed out that to those of ordinary skill in the art, On the premise of the utility model method is not departed from, some improvements and modifications can also be made, these improvements and modifications are also considered as The protection domain of this patent.
