It is poor with effect, cause the utilization rate in the case of equipped with lid still not high.
The content of the invention
To solve the above problems, the invention discloses a kind of screw group not easily to fall off.
A kind of screw group not easily to fall off, including screw and block, the screw are that one end is tip self tapping end, the other end
For planar ends, the block is arranged on screw, and block left end is annular absorption circle, and elastic layer, block are set on the outside of absorption circle
Right end sets cover plate, and side, which is set, in the cover plate puies forward string holes, and the absorption circle thickness is no more than the 2 of planar ends thickness
Times, it is connected, is an integral structure, outside is erosion resistant coating, and block right end diameter is more than left end with absorption circle on the inside of the cover plate
Diameter.
The present invention on the basis of the function of basic screw is ensured, sets block in screw in planar ends, pacify in screw
After the completion of dress, block is covered, so as to fill screw hole, protects screw, and because block is not easy to remove, and guarantee block is use up with screw hole
Measure equal, so safer, matching effect is good.
Absorption circle is set in the block of the present invention, can be adsorbed in planar ends, installation is simple, not easily to fall off, covers at the same time
On cover board set put forward string holes, need dismantle block when can also simple operations, there is very high flexibility, it is highly practical.
As a modification of the present invention, cast iron layer is set in the planar ends, flat recess or ten is set in cast iron layer
Word groove.
The shape of common screwdriver can be set in the cast iron layer of the present invention, and cast iron layer has preferable magnetic conductivity,
Block can be preferably sucked, ensures that block is not easily to fall off, usage time is longer, and protection screw is from corrosion.
As a modification of the present invention, the absorption circle is magnet circle.
The absorption circle of the present invention uses the relatively conventional magnet circle being easy to get, and reduces overall cost, and material is simple and easy to get, and inhales
Attached power is strong, and corrosion-vulnerable etc., does not last a long time.
As a modification of the present invention, the string holes section that carries is T-shaped through hole.
Carrying for the present invention can reserve wire etc. in string holes, can carry out dragging dismounting, while T-shaped hole can use spiral shell
The common instruments such as silk knife stir dismounting block, product utilization is had stronger flexibility.
As a modification of the present invention, the block left end maximum gauge is no more than 1.5 times of planar ends, cover plate
Diameter is no more than 2 times of planar ends.
The block matching screw of the present invention, according to common perforate mode, ensures that block can be embedded in screw hole, preferably
Cover screw, protection screw suffer erosion, and parallel with screw hole surface, and not easily to fall off, service life is longer.
The beneficial effects of the invention are as follows：
A kind of screw group not easily to fall off of the present invention, the present invention is in screw on the basis for the function of ensureing basic screw
On, block is set in planar ends, after installation is complete in screw, covers block, so as to fill screw hole, protects screw, and because lid
Cap is not easy to remove, and ensures that block is as far as possible equal with screw hole, so safer, matching effect is good, and absorption circle is set in block,
It can be adsorbed in planar ends, installation is simple, not easily to fall off, while is set in cover plate and put forward string holes, when needing to dismantle block
Can also simple operations, there is very high flexibility, it is highly practical.
