Description

Bolt

Technical field

Standard component field is the utility model is related to, more particularly to a kind of bolt.

Background technology

Bolt is a kind of common standard component, it is used cooperatively during use with nut, it mainly includes head And screw rod, such as the Chinese patent that notification number is CN10689914A discloses a kind of sealing fastening type bolt, including screw head, Screw rod, the screw head are the hexagonal screw head that cross section is regular hexagon, and the screw rod is fixed in screw head bottom connection, The screw head, the vertical central axis of screw rod are on bar straight line, and the screw rod is cylindrical structure, and the screw rod is close The end of screw head, which is set, is enclosed with layer sealing fastened layer, wherein, the sealing fastened layer is mass of expanded graphite.Pass through above-mentioned side Formula, bolt are provided with section sealing fastened layer on the screw rod close to screw head end, can effectively ensure that the fastening patch between bolt and hole Conjunction property and leakproofness, avoid bolt when screwing there is a situation where good with nut coaxial rotating, stability, fixation is nonvoluntary Rotate and sealing effect is good, it is highly practical.

But common bolt is all the head of regular hexagon, and need to use T-bolt in some special occasions, and The head of T-bolt is square, so needs to find or manufactures new T-bolt so that the bad adaptability of bolt.

Utility model content

The purpose of this utility model is to provide a kind of bolt, has good applicability.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of bolt, including head and screw rod, the head include middle part square and the piecemeal of both sides, the piecemeal It is detachably connected with square.

The head of bolt is provided with 3 parts to form, square and the screw rod at middle part are fixed, therefore in bolt normal use The piecemeal of both sides can be loaded onto, bolt disclosure satisfy that normal use requirement, and need to use T-bolt running into specific occasion When, can be by under the blocked breaking of both sides so that bolt can be used when T-bolt again, more applicability, disclosure satisfy that not With the needs of occasion.

The utility model is further set：Mounting hole is offered on the square, is convexly equipped with the piecemeal and mounting hole The pillar of cooperation, the pillar are threadedly coupled with mounting hole.

Piecemeal is threadedly coupled realization with mounting hole by pillar and is detachably connected, and the mode fastness being threadedly coupled is good, Piecemeal will not be deviate from from mounting hole, and whens installation or removal need to only rotate piecemeal, simple and convenient quick.

The utility model is further set：The straight slot through side wall is offered on the square, is convexly equipped with the piecemeal The inserted block coordinated with straight slot, the end of the inserted block are embedded with magnet piece and mutually abut.

Piecemeal is plugged in straight slot by inserted block, is then fixed by the magnetic force of magnet piece, and dismounting when only needs Firmly extract, such mode make it that the dismounting of piecemeal is very convenient.

The utility model is further set：The straight slot is in polygonized structure.

Straight slot is set into the structure in polygon, the structure of polygon enables to the piecemeal after installation not rotate, this Sample can increase the stability of piecemeal installation.

The utility model is further set：The shrinkage pool of regular hexagon is offered on the square.

The shrinkage pool of regular hexagon potentially acts as reserved handle hole and uses, when needing rotating bolt, allen wrench energy Enough it is inserted into shrinkage pool and is operated.

The utility model is further set：Limiting plate is threaded with the screw rod, the limiting plate is abutted and is bonded In piecemeal surface.

The setting of limiting plate can increase the mounting stability of piecemeal, then limiting plate is turned to the table for being connected to piecemeal Face, at this time limiting plate can limit the rotation of piecemeal so that the normal use that bolt can be stablized, and limiting plate potentially acts as Gasket uses, and can preferably protect the end face of bolt head, is only needed to change when position-limited edge surface abrasion is severe after long-time service Limiting plate.

The utility model is further set：The square is combined into regular hexagon structure with piecemeal.

So so that the head of bolt is still regular hexagon, therefore spiral shell can be sleeved on by outer hexagonal spanner in some occasions Operated at the head of bolt.

Embodiment

The utility model is described in further detail below in conjunction with attached drawing.

This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but As long as all protected in the right of the utility model be subject to Patent Law.

Embodiment 1：A kind of bolt, as depicted in figs. 1 and 2, including head 1 and screw rod 2, wherein head 1 include middle part The square 11 and the piecemeal 12 of both sides fixed with screw rod 2, side is convexly equipped with pillar 3 on piecemeal 12, and in square 11 On offer mounting hole 4 with 3 thread fitting of pillar so that piecemeal 12 can be real by the thread fitting of pillar 3 and mounting hole 4 Now it is detachably connected, therefore the piecemeal 12 of both sides can be loaded onto in bolt normal use, bolt disclosure satisfy that normal use will Ask, and when running into specific occasion and needing to use T-bolt, the piecemeal 12 of both sides can be pulled down so that bolt can work as T again Type bolt is used, more applicability, disclosure satisfy that the needs of different occasions, and the mode fastness being threadedly coupled is good, point Block 12 will not be deviate from from mounting hole 4, and whens installation or removal need to only rotate piecemeal 12, simple and convenient quick.

In order to further improve the connectivity robustness of piecemeal 12 and square 11, limiting plate 9 is threaded with screw rod 2, The limiting plate 9 abuts and fits in 12 surface of piecemeal, and the setting of limiting plate 9 can increase the mounting stability of piecemeal 12, then Limiting plate 9 is turned to the surface for being connected to piecemeal 12, limiting plate 9 can limit the rotation of piecemeal 12 at this time so that bolt energy Enough stable normal uses.

The shrinkage pool 8 of regular hexagon is offered at the middle part on head 1, shrinkage pool 8 potentially acts as reserved handle hole and uses, and is needing When wanting rotating bolt, allen wrench can be inserted into shrinkage pool 8 and be operated.

And piecemeal 12 and the splicing of square 11 are in the head 1 of regular hexagonal prism shape, therefore can be pulled in some occasions by outer-hexagonal Gloves are operated at the head 1 of bolt.

Embodiment 2：A kind of bolt, as shown in figure 3, its with embodiment 1 difference lies in piecemeal 12 removably not Together, the present embodiment is convexly equipped with inserted block 5 on piecemeal 12, which is square, and offers on square 11 and coordinate with inserted block 5 Straight slot 6, while be embedded with magnet piece 7 in the end of square 11, being plugged into 6 inner end of straight slot in inserted block 5 mutually abuts, point Block 12 is plugged in straight slot 6 by inserted block 5, is then fixed by the magnetic force of magnet piece 7, only need to firmly be pulled out when dismounting Go out, such mode make it that the dismounting of piecemeal 12 is very convenient.
