Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of hexagon head plug screw without the need to just realizing installing or removing by spanner.
For achieving the above object, the utility model provides following technological scheme: a kind of hexagon head plug screw, comprise plug screw head and screw rod, the end face of described plug screw head is provided with putting hole, the tool rod be mated is provided with in described putting hole, the sidewall of described plug screw head is provided with the jack coordinated with tool rod, and described jack is uniformly distributed in plug screw head sidewall.
Further, described tool rod comprises and cutting graftage part and crawl section, and the diameter of described crawl section is greater than the diameter of cutting graftage part, and described plug screw end surface is provided with the groove coordinated with crawl section.
Further, be provided with elastic component bottom described putting hole, described recess sidewall is provided with the block stopping that crawl section is deviate from from groove, and edge, described crawl section is provided with the breach coordinated with block.
Further, described crawl section end face is provided with the raised line radially arranged.
Further, the surface that described plug screw head is connected with screw rod is provided with annular groove, is provided with O RunddichtringO in described annular groove, and the cross section of described annular groove is swallow-tail form, and O RunddichtringO part is positioned at annular groove outside.
Compared with prior art, the utility model has the advantage of: in some accidents or do not carry the situation of the instruments such as spanner time, the tool rod be placed in putting hole is taken out, then tool shaft end portion one end is plugged in the jack of plug screw head sidewall, and then the pulling tool bar the other end, the installation that can realize plug screw fast can be dismantled, without the need to the wrench operated by outside in whole process, the tool rod carried by it just can be realized, have more applicability, can be put back in putting hole in less than tool rod at ordinary times, do not affect overall appearance, jack is uniformly distributed in plug screw head sidewall, more laborsaving when operating, after turning an angle, continuation operation in another jack can be placed in by puller bar, even if the place very little in space still can be good at complete operation.

Reference character: 1, plug screw head; 2, screw rod; 3, tool rod; 31, crawl section; 32, cutting graftage part; 4, jack; 5, groove; 6, rubber pad; 7, block; 8, breach; 9, raised line; 10, annular groove; 11, O RunddichtringO.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model hexagon head plug screw embodiment is described further.
A kind of hexagon head plug screw, comprise plug screw head 1 and screw rod 2, the end face of plug screw head 1 is provided with putting hole, the tool rod 3 be mated is provided with in putting hole, the sidewall of plug screw head 1 is provided with the jack 4 coordinated with tool rod 3, jack 4 is uniformly distributed in plug screw head 1 sidewall, and wherein plug screw head 1 is regular prism, and the number of jack 4 is preferably 6 and is separately positioned on six sidewalls of plug screw head 1.
In some accidents or when not carrying the situation of the instruments such as spanner, the tool rod 3 be placed in putting hole is taken out, then one end, tool rod 3 end is plugged in the jack 4 of plug screw head 1 sidewall, and then pulling tool bar 3 the other end, the installation that can realize plug screw fast can be dismantled, without the need to the wrench operated by outside in whole process, the tool rod 3 carried by it just can be realized, have more applicability, can be put back in putting hole in less than tool rod 3 at ordinary times, do not affect overall appearance, jack 4 is uniformly distributed in plug screw head 1 sidewall, more laborsaving when operating, after turning an angle, continuation operation in another jack 4 can be placed in by puller bar 3, even if the place very little in space still can be good at complete operation.
Wherein tool rod 3 comprises and cutting graftage part 32 and crawl section 31, and the diameter of crawl section 31 is greater than the diameter of cutting graftage part 32, and plug screw head 1 end face is provided with the groove 5 coordinated with crawl section 31.
Wherein be provided with elastic component bottom putting hole, groove 5 sidewall is provided with the block 7 stopping that crawl section 31 is deviate from from groove 5, and edge, crawl section 31 is provided with the breach 8 coordinated with block 7.
Wherein crawl section 31 end face is provided with the raised line 9 radially arranged.
By above-mentioned such setting, when not using tool rod 3, crawl section 31 sinks in groove 5, make plug screw integrity and aesthetic property more, now breach 8 and block 7 are staggered positions for they, block 7 blocks crawl section 31 and avoids its situation about ejecting from groove 5 under the effect of elastic component to occur, when needing to use tool rod 3, crawl section 31 is rotated by catching the raised line 9 be arranged on the end face of crawl section 31, rotating operation is easily laborsaving, rotate the position that crawl section 31 to breach 8 is corresponding with block 7, and then crawl section 31 can be ejected from groove 5 part under the effect of elastic component, thus crawl section 31 can be caught easily to be extracted out in putting hole by tool rod 3, then be inserted on jack 4 and carry out installation or removal operation, wherein elastic component can be spring or rubber pad 6 etc., the present embodiment preferred elastomeric part is rubber pad 6, rubber pad 6 stability is more remarkable.
The surface that wherein plug screw head 1 is connected with screw rod 2 is provided with annular groove 10, is provided with O RunddichtringO 11 in annular groove 10, and the cross section of annular groove 10 is swallow-tail form, and it is outside that O RunddichtringO 11 part is positioned at annular groove 10.
Traditional plug screw is all just threaded connection and realizes sealing, occur damaging the situation that just there will be leakage once threaded connection place sealing, double seal can be realized with being threaded by arranging O RunddichtringO 11 on plug screw head 1, better sealing can be realized, the annular groove 10 of swallow-tail form makes the installation of O RunddichtringO 11 more stable, not easily deviate from from annular groove 10, can load in annular groove 10 by the elasticity of O RunddichtringO 11 self during installation, and the sealing surface of O RunddichtringO 11 is linear sealing, active force can be produced to O RunddichtringO 11 when there being liquid to flow out, O RunddichtringO 11 has axis, radial direction all can auto-compensation, overcome the not enough problem of sealing force, sealing is reliable.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
