Description

A kind of easy-to-dismount bolt
Technical field
The utility model relates to a kind of fastening piece, and more particularly, it relates to a kind of easy-to-dismount bolt.
Background technique
Bolt, by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, its structure is simple, for connecting two parts with through hole.Divide by nose shape: have hexagonal, round end, countersunk head etc.This bolt usually need extra size suitable pull or other instruments are tightened.In some occasion, the instruments such as the spanner such as carried or screw-driver and Bolt sizes inconsistent time, be just difficult to bolt tightening or unclamp, this be problems demand solve.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of bolt of easy to use, convenient disassembly.
For achieving the above object, the utility model provides following technological scheme:
A kind of easy-to-dismount bolt, screw rod under comprising regular hexagon bolt head and being fixed on bolt head, described bolt is provided with cavity, and described cavity cross section is regular hexagon, described bolt is also provided with the middleware matched with cavity, is provided with elastic component between described middleware and cavity.
Preferably, described middleware is provided with limiting stopper, and described cavity sidewalls is provided with the restraining groove matched with limiting stopper.
Preferably, described limiting stopper is the twice of bolt head thickness to the distance at middleware top.
Preferably, described middleware end face is provided with cross recess.
Compared with prior art, the beneficial effects of the utility model are: the screw rod under described bolt comprises regular hexagon bolt head and is fixed on bolt head, can turn with inner hexagon spanner, described bolt is provided with cavity, described cavity cross section is regular hexagon, described bolt is also provided with the middleware matched with cavity, so middleware is six prisms, elastic component is provided with between described middleware and cavity, middleware is ejected, described middleware is higher than bolt head top, both middleware was equivalent to the bolt head of another size, can turn with another size inner hexagon spanner, and can middleware be headed in cavity, form a hexagonal countersunk screw, can turn with hexagon wrench, the instrument of the adaptive 3 kinds of models of bolt energy of the utility model design, greatly reduce instrument and the inconsistent situation of Bolt sizes.

Embodiment
With reference to accompanying drawing, a kind of easy-to-dismount screw embodiment of the utility model is described in further details.
Referring to figs. 1 to Fig. 6, described bolt 1 comprises regular hexagon bolt head 11 and the screw rod 12 under being fixed on bolt head 11, regular hexagon bolt head 11 can be turned with inner hexagon spanner, also cavity is provided with in described bolt 1, described cavity cross section is regular hexagon, described bolt 1 is also provided with the middleware 2 matched with cavity, so described middleware 2 is six prisms, middleware 2 coordinates with cavities seals, elastic component 3 is provided with between described middleware 2 and cavity, and middleware 2 is ejected, described middleware 2 is higher than bolt head 11 top, both middleware 2 was equivalent to the bolt head 11 of another size, middleware 2 can be turned with another size inner hexagon spanner, and drive bolt 1, and can middleware 2 be headed in cavity, form a hexagonal countersunk screw 1, can turn with hexagon wrench, described middleware 2 end face is provided with cross recess 6, make Phillips screwdriver and straight screwdriver can turn middleware 2 to drive bolt 1, the instrument of the adaptive 5 kinds of models of bolt 1 energy of the utility model design, greatly reduce instrument and the inconsistent situation of bolt 1 size.
With reference to figure 3 and Fig. 6; described middleware 2 is provided with limiting stopper 4; described cavity inner wall is provided with restraining groove 5; not only strengthen middleware 2 and coordinating and limiting the position that middleware 2 slides between cavity; middleware 2 can not be deviate from and protect elastic component 3; and described limiting stopper 4 is the twice of bolt head 11 thickness to the distance at middleware 2 top, ensure that the part that middleware 2 protrudes is equal with bolt head 11 thickness, makes the instrument that the adaptive degree of depth of bolt 1 is consistent.
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.
