Description
Technical field
The utility model relates to a kind of screw assembly, is specifically related to one and exempts from tool operation screw assembly.
Background technique
Parts in motorcycle helmet are connected and are generally connected by screw, usually need during connection to use supporting instrument to operate, but carrying implement is also inconvenient under many circumstances, use during tool operation and also need certain operating space, the screw of therefore exempting from tool operation has more wide market prospects.General at present to exempt from tool operation screw assembly structure more complicated, convenient and practical not, and study a kind of structure simple, convenient and practical tool operation screw assembly of exempting from is the current market demand.
Model utility content
It is simple that the purpose of this utility model is to provide a kind of structure, and convenient and practical exempts from tool operation screw assembly.
The technological scheme that the utility model adopts is mainly: one exempts from tool operation screw assembly, comprise stubborn hand handle, nut, plate body and screw rod, described plate body center has through hole, plate body surface is provided with stubborn hand suitable plate body groove, be formed with a cylinder bottom nut stretch out body and extend in through hole, pushed down spacing after stubborn hand handle inserts plate body groove by nut, cylinder stretches out body and has tapped hole, screw rod comprises the lower screw section that screw section and diameter are greater than screw section, upper screw section is connected with tapped hole, and lower screw section is connected to the bottom of plate body; Twisting hand drives plate body to rotate by plate body groove, and plate body drives nut to link by pit that plate body and nut are arranged respectively and salient point.
Further, be provided with bottom described nut corresponding with plate body groove location, with described stubborn hand suitable nut groove.
Further, described plate body is provided with overlap joint platform, twists hand and foldable is being overlapped on platform.
Further, described overlap joint platform edges is provided with subsidence area.
Further, described stubborn hand is the hand draw ring structure be bent into for a kind of cylinder.
Further, described stubborn hand is 0 ° to 90 ° rotational angle range in plate body groove.
The beneficial effects of the utility model are:
One of the present utility model exempts from tool operation screw assembly, can when not by external tool, with hand turn stubborn hand time, twisting hand drives plate body to rotate by plate body groove, plate body drives nut interlock by salient point and pit, screw rod is and then rotated, thus completes the disassemble and assemble work of screw.The utility model structure is simple, convenient and practical, and cost compare is low, and applicable occasion of being inconvenient to carry screw dismounting tool uses.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 4, Fig. 5 and Fig. 6, one of the present utility model exempts from tool operation screw assembly, comprise stubborn hand 1, nut 2, plate body 3 and screw rod 4, described plate body 3 center has through hole 31, plate body 3 surface is provided with stubborn hand 1 suitable plate body groove 32, be formed with a cylinder bottom described nut 2 stretch out body 21 and extend in through hole 31, twisting after hand inserts plate body groove 32 1 pushes down spacing by nut 2, described cylinder stretches out body 21 and has tapped hole 22, screw rod 4 comprises the lower screw section 42 that screw section 41 and diameter are greater than screw section 41, described upper screw section 41 is connected with tapped hole 22, lower screw section 42 is connected to the bottom of plate body 3, twisting hand drives plate body 3 to rotate 1 by plate body groove 32, and plate body 3 drives nut 2 to link by pit 33 that plate body 3 and nut 2 are arranged respectively and salient point 23, makes screw rod 4 and then rotation, thus completes the disassembling operations of screw.
With reference to Fig. 1 and Fig. 4, be also provided with bottom described nut 2 corresponding with plate body groove 32 position, and stubborn hand 1 suitable nut groove 24.When being pushed down by the nut groove 24 bottom nut 2 after stubborn hand inserts plate body groove 32 1, spacing more firm.Twist when hand rotates 1 directly to drive nut 2 to rotate by nut groove 24 simultaneously, thus makes screw rod 4 screw or screw out.
With reference to Fig. 2 and Fig. 5, described plate body 3 is also provided with overlap joint platform 34, twists hand 1 after the dismounting completing screw, with hand, stubborn hand can be superimposed on 1 pressing on overlap joint platform 34, reduce the space of twisting hand and taking 1.
With reference to Fig. 2 and Fig. 5, described overlap joint platform 34 edge is also provided with subsidence area 35, preferably, subsidence area 35 is arranged on platform 34 edge perpendicular with plate body groove 32 direction, when stubborn hand is superimposed on overlap joint platform 34 1,1, and then stubborn hand carries out screw disassembling operations 1 can be turned with hand stubborn hand from subsidence area 35 easily plate.
With reference to Fig. 1, Fig. 2 and Fig. 3, described stubborn hand is preferably 1 the hand draw ring structure that a kind of cylinder is bent into, simple and practical.
With reference to Fig. 1 and Fig. 2, twist hand can do 0 ° to 90 ° in plate body groove 32 rotation 1.When carrying out the disassembling operations of screw, hand will be twisted and rotate to proper angle 1, easy-to-operat; When completing the dismounting of screw, then hand will be twisted 1 rotation to 0 °, by twisting hand superimposed for 1 pressing to overlapping platform 34.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, as long as the technological scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
