Abstract
The utility model discloses an oil filtering bolt. The oil filtering bolt comprises a head part and a screw rod as well as a tool withdrawal groove arranged at the connecting part between the head part and the screw rod, wherein the cross section of the tool withdrawal groove is cone-shaped or V-shaped. As a combined gasket can be automatically centered by the cone-shaped or V-shaped tool withdrawal groove of the oil filtering bolt to cover a threaded hole all the time so as to prevent oil leakage, therefore, the tightness is improved.
Description
Technical field
The utility model relates to the link field, particularly a kind of whelk bolt of crossing.
Background technique
Cross oil (water, gas) bolt and be used for sealing the tapped through hole on diesel oil on the diesel engine, machine oil, water, the feed channel.At present, the known head of whelk bolt excessively and the tool withdrawal groove of screw rod joint are the rectangle annular groove, usually are used the tapped through hole of compound gasket deformable seal pipeline under the compressing of crossing the whelk bolt head with compound gasket.
But because the existence of rectangle tool withdrawal groove screwed in the whelk bolt process, compound gasket can not automatic centering; May be partial to one side of rectangle tool withdrawal groove after the installation; Cause compound gasket on one side near the rectangle tool withdrawal groove, and another side away from, make the compound gasket gland not live tapped hole; Cause leaking, influence is to the sealing of pipeline.
The model utility content
The technical problem that the utility model solves provides a kind of whelk bolt excessively that can make the compound gasket automatic centering and then improve sealing.
For achieving the above object, according to the utility model a kind of whelk bolt of crossing is provided, comprising: head and screw rod, and the tool withdrawal groove that is opened in head and screw rod joint, the cross section of tool withdrawal groove is taper or V-arrangement.
Further, screw rod also offers oil duct.
Further, when crossing the assembling of whelk bolt and pipe joint, oil duct is communicated with pipe joint.
According to the technological scheme of the utility model, because this taper or V-arrangement tool withdrawal groove structure of crossing the whelk bolt can make the compound gasket automatic centering, cover tapped hole all the time, anti-heads, and then improve sealing.
Description of drawings
Fig. 1 is the assembly structure schematic representation of crossing the whelk bolt according to the utility model.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of embodiment.
Referring to Fig. 1, this is crossed whelk bolt 1 and comprises: head 11 and screw rod 12, and the tool withdrawal groove 13 that is opened in head 11 and screw rod 12 joints, the cross section of this tool withdrawal groove 13 is taper or V-arrangement.Screw rod 12 also offers oil duct 14.
During assembling, this is crossed whelk bolt 1 and penetrates pipe joint 4, and oil duct 14 is communicated with pipe joint 4.Be provided with compound gasket 2 between head 11 and the pipe joint 4, this compound gasket 2 is located on the screw rod 12, and inner ring is adjacent to the tool withdrawal groove 13 on the screw rod 12.Because the cross section of tool withdrawal groove 13 is taper or V-arrangement, in the process of screwing, taper or V-arrangement face can compress compound gasket 2 gradually; The position of adjustment compound gasket 2 inner rings and tool withdrawal groove 13; Make compound gasket 2 automatic centerings to make compound gasket 2 cover tapped hole all the time anti-heads.
The utility model is that this crosses the taper of oil (water, gas) bolt, V-arrangement tool withdrawal groove structure can make compound gasket 2 automatic centerings, makes compound gasket 2 cover tapped hole all the time, anti-heads.
More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
Claims (3)
1. cross the whelk bolt for one kind, comprising: head and screw rod, and the tool withdrawal groove that is opened in said head and screw rod joint is characterized in that the cross section of said tool withdrawal groove is taper or V-arrangement.
2. the whelk bolt of crossing according to claim 1 is characterized in that said screw rod also offers oil duct.
3. whelk bolt excessively according to claim 2 is characterized in that, when said whelk bolt excessively and pipe joint assembling, said oil duct is communicated with said pipe joint.
