The general name of used one kind machine components when part entirety.Its feature is that description is various, and performance purposes is different, Er Qiebiao
It is standardization, seriation, unitized strong.Fastener is most widely used mechanical basic part, is in great demand.And it is current
Many screw heads are equipped with the cross open agreed with for the head of Phillips screwdriver, but most cross open at present
All be open type, and unclosed, thus be easy to cause foreign matter and enter and influence the disassembly process in its later stage, dismounting it is inconvenient and
Artificial intensity is big.
Invention content：
The technical problem to be solved by the present invention is to：Offer one kind is simple in structure, installation is easy to make and can effectively cover in ten
The dust protected screw with covering members of word opening.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of dust protected screw with covering members, including head of screw and screw rod, the head of screw upper surface are equipped with cross
Groove, forwardly and backwardly symmetrical two first grooves of cross groove and symmetrical two the second grooves,
The inside cell wall of first groove is equipped with the first trepanning, and the inside cell wall of the second groove is equipped with the second trepanning, and described first
Trepanning, the second trepanning aperture towards the centrally disposed of cruciform groove and vertical with the central axes of screw rod, described first opens
The first expansion plate and the second expansion plate, the first expansion plate and the second flexible plate stretching are respectively equipped in hole and the second trepanning
When to extreme position, the free end edge abutting contact of two the first expansion plates, two the second expansion plates are born against first
Expansion plate both sides of the edge.
Preferably, first expansion plate and the second expansion plate are disposed as elastic telescopic plate.
Preferably, being equipped with the first compressed spring, institute between the end and the bottom hole of the first trepanning of first expansion plate
It states and is equipped with the second compressed spring between the end of the second expansion plate and the bottom hole of the second trepanning.
Preferably, the aperture of first trepanning, the second trepanning is equipped with annular rib, first expansion plate,
The tail end of two expansion plates is equipped with annular barrier rib.
Preferably, the free end top edge of first expansion plate, the second expansion plate is disposed as inclined side.
Preferably, the length of first groove is less than the length of the second groove.
Compared with prior art, usefulness of the present invention is：The dust protected bolt structure with covering members is simple,
It installs easy to make and simple and quick, and can effectively cover the cross open of screw head, and do not influence installing and dismounting,
It effectively prevent foreign matter to enter in opening, thus practicability is high, is suitble to promote and apply.
Description of the drawings：
The following further describes the present invention with reference to the drawings：
Fig. 1 is the partial top schematic cross-sectional view of the present invention.
Specific implementation mode：
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
All other embodiment that personnel are obtained without making creative work, shall fall within the protection scope of the present invention：
A kind of dust protected screw with covering members as shown in Figure 1, including head of screw 1 and screw rod, the head of screw upper end
Face is equipped with cross groove, forwardly and backwardly symmetrical two the first grooves 3 of the cross groove and symmetrical
Two the second grooves 4, the inside cell wall of first groove are equipped with the first trepanning 5, and the inside cell wall of the second groove is equipped with the
Two trepannings 6, first trepanning, the second trepanning aperture towards the centrally disposed of cruciform groove and with the central axes of screw rod
Vertically, the first expansion plate 7 and the second expansion plate 8, the first expansion plate are respectively equipped in first trepanning and the second trepanning
And second expansion plate when being stretched to extreme position, the free end edge abutting contact of two the first expansion plates, two second are stretched
Contracting plate is born against in the first expansion plate both sides of the edge.
In the present embodiment, for convenience of the first expansion plate, the free stretching motion of the second expansion plate, first expansion plate with
And second expansion plate be disposed as elastic telescopic plate, preferably, the end of first expansion plate is opened with first
It is equipped with the first compressed spring 9 between the bottom hole in hole, the is equipped between the end and the bottom hole of the second trepanning of second expansion plate
Two compressed springs 10, thus, when the first expansion plate, the second expansion plate, which are in, does not stress state, the first expansion plate, second stretch
Plate stretches out the first trepanning and the second trepanning under the action of the first compressed spring, the second compressed spring respectively, to cover in
Cross open avoids foreign matter from entering, and when needing to turn screw, it is only necessary to the head of Phillips screwdriver is squeezed first and is stretched
Plate, the second expansion plate can enter cross open, will not influence to actually use.
In the present embodiment, first trepanning, the second trepanning aperture be equipped with annular rib, described first is flexible
Plate, the second expansion plate tail end be equipped with annular barrier rib, thus effectively the first expansion plate, the second expansion plate is avoided to skid off first and opened
Hole and the second trepanning.
Squeezed into cross open for convenience of the head of screwdriver, first expansion plate, the second expansion plate free end on
Edge is disposed as inclined side 11.
In the present embodiment, the length of first groove is less than the length of the second groove.
The above-mentioned dust protected bolt structure with covering members is simple, and installation is easy to make and simple and quick, and can have
Effect covers the cross open of screw head, and does not influence installing and dismounting, and foreign matter is effectively prevent to enter in opening, and practicability is high.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not the present invention made in any form
Limitation, it is every according to the technical essence of the invention to any simple modification, equivalent change and modification made by above example,
In the range of still falling within technical solution of the present invention.
