Description
Technical field
The utility model relates to the rotatable screw of a kind of hand, refers in particular to a kind of rotation set, screw and after cap combined, this screw can firmly be incorporated into the rotatable screw of hand in the rotation set surely.
Background technique
Press screw and nut in people's daily life as screwing device, to link both non-article that are wholely set finding is arranged more because the setting by screw and nut, so itself and by the preferable binding strength of tool between closure.
Because screw and nut are mechanically indispensable connecting part, if both get loose, then the performance of whole machinery and precision promptly are greatly affected, and this mechanically is not allow generation in high speed and high precision especially.And on the whole the structure of general screw is divided into bar portion and head, bar portion periphery tool screw thread, make increase when screwing togather with article between combine fastness, head then section is bigger, it is intended to use for the chimeric application of force of instrument.And head is set partly for instrument, some variations are also arranged, except that known yi word pattern or cross, central part tool depression hole slot is still arranged, and this depression hole slot can be triangle, square, hexagon ..., or be the equiangular polygon section, and it is when construction, then be with corresponding bottle opener of a section configuration size or spanner, set, be beneficial to rotate the application of force into this hole slot or this head of socket.
Because the operation that screws togather of conventional screw all needs with instrument, for example bottle opener or spanner if in the occasion of not having these instruments, then can't carry out the combination between article, very are inconvenience.Based on aforementioned disappearance, the dealer is about to traditional screw with the flush type injection molding method at present, its head is coated in the plastics cylinder, and this damaged surface ring is established a plurality of burrs, be beneficial to the gripping and the rotation of hand, and the screw of this pattern is the rotatable screw of hand that is commonly called as.
Though the rotatable screw of this hand has the advantage that the instrument of exempting from can screw togather, only its disappearance is, because of difference by closure short the differing of bar minister of palpus screw, and can't be adaptation with the single mold, so that the rotatable screw of hand of different bar portion size, corresponding flush type injection forming mold promptly need be arranged, real non-one good solution.
Remarkable disappearance based on the rotatable screw of hand of aforementioned flush type ejection formation, relevant dealer promptly develops the rotatable screw of hand as shown in Figure 1, and it is a hollow rotation set A, and diapire A1 central authorities open a bar hole, pass through for the B1 of bar portion of screw, head B2 is then ccontaining and be positioned the bottom of this rotation set A; Wherein, each vertically offers one section profile groove A2 this rotation set A two opposite side walls, and each profile groove A2 top oblique tenon A3 that supports in that extends internally, so that prop up the head B2 of screw, then encircles in this rotation set A top surface in addition and establishes a plurality of burrs A4.The advantage of the rotatable screw of this hand is, but the different jack per line screw of its B1 of connecting rod portion size.Only for the standard of screw, it is the specifications section of standard head B2 only, does not limit the thickness of this head B2, so that if head B2 is too thin, will cause whole screw loosening in rotation set A; Then can't be this tenon A3 institute clip location of balancing or cancel each other if head B2 is too thick, and can't be with both combinations.In addition, the tenon A3 that balances or cancel each other of this rotation set A is moulding by forced stripper mechanism, and consequently intilted angle and length are promptly limited to, and can't prop up the head B2 of screw effectively, and both are separated easily.Even the open top A5 of this rotation set A is open shape, and influences its overall appearance, if during sealed tension, only merely opens with hand-screw, probably has unable to do what one wishesly, and demands urgently improving.
The model utility content
The rotatable screw of a kind of hand of the purpose of this utility model in the hope of reaching in conjunction with firmly, is difficult for getting loose, and tool is covering property well, and the purpose that can utilize instrument to screw or unscrew.
For achieving the above object, the rotatable screw of the hand that the utility model provides comprises:
One hollow rotation set, it axially offers the tube hole of a polygon section, and its diapire central authorities open a bar hole, and this rotation set sidewall is vertically offered one section profile groove relatively;
One screw, its lower head that ties up to a polygon section extend a bar portion with continuous thread, and the bar hole is passed through by this bar portion, and head then ccontaining be positioned a positioning part of bottom, hole;
One cap, its top has a disk cover, this corresponding each profile groove position longitudinal extension one fin in disk cover bottom, and the protruding clasp in bottom, so that be buckled in this in the profile groove, this connects a press fixing piece to the fin root edge, forms so that press the head of screw.
The rotatable screw of described hand, wherein this polygon section is a hexagon.
The rotatable screw of described hand, wherein this spiral cover top ring is established a plurality of burrs.
The rotatable screw of described hand, wherein the tube hole open top of this spiral cover forms rank, and it is in order to the disk cover of ccontaining this cap.
The rotatable screw of described hand, wherein this press fixing piece is an arc.
The rotatable screw of described hand, wherein this disk cover bottom surface is to the abaculus of the downward projection one identical section in tube hole that should the polygon section, with this hole sealing and connect airtight.
The rotatable screw of described hand, wherein this disk cover end face is provided with a depression hole slot.
The rotatable screw of described hand, wherein this hole slot is an in-line or cross, or its combination.
Via enforcement of the present utility model, this cap utilizes the clasp of two fins to be snapped in a pair of profile groove of rotation set, and be closely combination, but the press fixing piece of being stretched by elasticity between this two clasp in addition pushes against the head of screw, makes the head thickness difference of its unlikely coping screw produce loosening situation.In addition, because of cap combine with spiral cover firmly, even if make screw suffer external force, the embarrassed shape that also unlikely generation separates with rotation set.This cap can seal the tube hole opening of spiral cover completely, and increases outside its integrity aesthetic feeling, and its outside can establish a depression hole slot in addition, go to the limit with hand-screw after, still can be screwed or be unscrewed by instrument.
