It is used in combination for big primary screw.Screw industrially bears vital task, as long as there is industry on the earth, then the function of screw is eternal
It is important.Screw is joint invention over the past thousands of years in people's production and living, from the point of view of application field, and it is the first big of the mankind
Invention.Main purpose often occur to make industrial product composition be fixed as one, in use between tooth and tooth can not adherence, excessively use
Then screw terminal dialysis or the bad not tight of tooth line etc. fail to reach use condition for power locking, are all the precision problem of quality.At present
When in use, cap nut is easily exposed to outside to many screws after installing, and can many times influence attractive in appearance, and
And can encounter when sometimes child is at play on cap nut, it is very dangerous, therefore devise a kind of combined screw.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of combined screw, including cap nut and spiral shell
Screw mandrel, is removable connection between the cap nut and lead screw, and screw groove, the screw are provided with the outside of the lead screw
Cap lower end, which is provided with boss, the boss, is provided with yi word pattern double wedge, and the lead screw upper end is provided with and yi word pattern double wedge
The yi word pattern groove of matching, the cap nut upper end is provided with antitheft groove, the antitheft groove and is provided with centralized positioning post.
As a kind of preferred technical scheme of the utility model, antiskid glue cushion is provided between the boss and lead screw,
The antiskid glue cushion is made of EVA material.
As a kind of preferred technical scheme of the utility model, the lead screw lower end is provided with tip, the tip
It is provided with tapping.
As a kind of preferred technical scheme of the utility model, six rib type projections are provided with the outside of the centralized positioning post.
Compared with prior art, the beneficial effects of the utility model are：Pass through dismountable cap nut and the knot of lead screw
Structure is designed so that screw when in use, can be good at installing and dismantle, cap nut is disassembled after installing, it is to avoid
Cap nut influence is attractive in appearance, and can prevent the nut of screw from protruding after dismounting, it is to avoid child falls down to collide and hit on screw
Wound, guarding against theft type design, improves the security of screw, is worthy to be popularized.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model cap nut top view.
In figure：1- cap nuts, 2- lead screw, 3- screw grooves, 4- boss, 5- yi word pattern double wedges, 6- yi word pattern grooves, 7-
Antitheft groove, 8- centralized positioning posts, 9- antiskid glue cushions, 10- tips, 11- tappings, the rib type projections of 12- six.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of combined screw, including the He of cap nut 1
Lead screw 2, is removable connection between cap nut 1 and lead screw 2, and the outside of lead screw 2 is provided with screw groove 3, cap nut 1
End, which is provided with boss 4, boss 4, is provided with yi word pattern double wedge 5, and the upper end of lead screw 2 is provided with one matched with yi word pattern double wedge 5
Font groove 6, the upper end of cap nut 1 is provided with antitheft groove 7, antitheft groove 7 and is provided with centralized positioning post 8, boss 4 and screw
Antiskid glue cushion 9 is provided between bar 2, antiskid glue cushion 9 is made of EVA material, the lower end of lead screw 2 is provided with tip 10, tip
Tapping 11 is provided with 10, the outside of centralized positioning post 8 is provided with six rib type projections 12.
The utility model when in use, is inserted in groove by special instrument, the centralized positioning post that inside is set
Six rib type projections are coordinated to increase bonding strength, rotary screw cap so that lead screw is entered by the tapping of screw groove and lower end
Enter in workpiece, the design of boss allows lead screw to be absorbed in certain depth inside workpiece, antiskid glue cushion prevent cap nut with
Lead screw loosens, and yi word pattern double wedge coordinates yi word pattern groove to enter lead screw spiral shell in workpiece, then extracts cap nut out, can be by close
