Embodiment
The technical problem solved to make the utility model, the technological scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further embodiment of the present utility model.
Referring to figs. 1 to Fig. 4, the utility model provides a kind of anti-loose attachment means, comprise bolt, described bolt has the first thread section 1 near its backstop limit, and the second thread section 2 to be connected with the first thread section 1, bolt all has only rib structure, and this belongs to the common practise of those skilled in the art.Bolt of the present utility model has two thread sections, be followed successively by the first thread section 1, second thread section 2, and described first thread section 1 moves towards contrary with the screw thread of the second thread section 2 from its backstop limit toward its free end direction.Such as the first thread section 1 is the screw thread of trend clockwise, then the second thread section 2 is the screw thread of trend counterclockwise; Or the first thread section 1 is the screw thread of trend counterclockwise, then the second thread section 2 is the screw thread of trend clockwise.In the mode of execution that the utility model one is concrete, the external diameter of described first thread section 1 is greater than the external diameter of the second thread section 2, and the two position connected at it forms a step.
Attachment means of the present utility model, also comprises the mother nut 3 for being locked on the first thread section 1, and is locked at the secondary nut 6 on the second thread section 2, with reference to figure 2, Fig. 3; Be provided with the internal thread coordinated with the first thread section 1 in mother nut 3, in described secondary nut 6, be provided with the internal thread 7 coordinated with the second thread section 2.When in use, first mother nut 3 passed the second thread section 2 and is locked on the first thread section 1, and then being locked on the second thread section 2 with secondary nut 6.
Attachment means of the present utility model, also comprises outer sleeve, and with reference to figure 4, described outer sleeve comprises the first sleeve 10 for meshing together with mother nut 3 outer wall, and is connected with the first sleeve 10 and the second sleeve 12 for engaging with secondary nut 6 outer wall.The outer wall of such as mother nut 3 is traditional outer-hexagonal shape, then the first sleeve 10 is Hexagonal jacket in being mated, and the two is combined together; Same reason, the outer wall of secondary nut 6 is traditional outer-hexagonal shape; And the second sleeve 12 is Hexagonal jacket in being mated.
Attachment means of the present utility model, when in use, first mother nut passed the second thread section and be locked on the first thread section, with secondary nut check on the second thread section, then outer sleeve is enclosed within mother nut, secondary nut, the outer wall of the first sleeve and mother nut is meshed together, and the outer wall of the second sleeve and secondary nut is meshed together.Attachment means of the present utility model, because the screw thread trend of the first thread section, the second thread section is contrary, the direction of rotation that mother nut, secondary nut come off, now adopt outer sleeve and mother nut, secondary nut synchronous together, this just makes a nut in the sense of rotation come off, another nut is then in the sense of rotation of locking, and the two restricts mutually, and attachment means of the present utility model can not be come off.
With reference to figure 1, Fig. 2, Fig. 3, if A position is the height waiting to lock workpiece, B position is for locking mother nut 3, and A+B equals the length of the first thread section 1.The height of mother nut 3 is that H2, C position is for locking secondary nut 6; Desirable locking state is: secondary nut 6 is against on the end face of mother nut 3.When termination lower than the first thread section 1 of the end face of locking state mother nut 3, time namely lower than stepped locations between the first thread section 1 and the second thread section 2, by at mother nut 3 and wait to lock between workpiece and set up pad 5, can be against on the end face of mother nut 3 to make secondary nut 6.
The utility model another preferred embodiment in, penetrating of described secondary nut 6 holds the 3rd sleeve 9 that is provided with for being inserted in the first thread section 1, with reference to figure 3.3rd sleeve 9 is fixed together with the end that penetrates of secondary nut 6.The outer wall of the 3rd sleeve 9 is hexagon, its inwall can be cylindrical, when termination lower than the first thread section 1 of the end face of locking state mother nut 3,3rd sleeve 9 is inserted in successively the second thread section 2, first thread section 1, while tightening secondary nut 6, the 3rd sleeve 9 is withstood on the end face of mother nut.
The utility model one preferred embodiment in, the size L1 of described secondary nut 6, the most width position of the 3rd sleeve 9 is less than or equal to the size L of the narrowest position of mother nut 3, so both ensure that secondary nut and mother nut have sufficient faying surface, did not affect penetrating of outer sleeve again.
If during locking, the end face of mother nut 3 is higher than the termination of the first thread section 1, and namely higher than the stepped locations between the first thread section 1 and the second thread section 2, when not affecting mother nut 3 working strength, major and minor nut all can normally use; Exceed the first thread section 1 termination at mother nut 3 too much, and when affecting its working strength, then illustrate and treat that locking workpiece is too thick, longer screw rod need be changed.
The utility model one preferred embodiment in, described 3rd sleeve 9 is external hexagonal sleeve, described secondary nut 6 cylindrically, the inwall of the outer wall of described secondary nut 6, the second sleeve 12 is provided with intermeshing tooth 8,13, and described tooth 8,13 distributes along the length direction of secondary nut 6, second sleeve 12.Adopt the mode of this engagement, make it possible to penetrate outer sleeve more smoothly, that is, the tooth 8 be more prone on outside the tooth 13 of the second sleeve 12 is easier and secondary nut 6 meshes together.
In view of the end that penetrates of secondary nut 6 is also provided with the 3rd sleeve 9, described outer sleeve also comprises the 4th sleeve 11 penetrated between the first sleeve 10, second sleeve 12 and for the 3rd sleeve 9.4th sleeve 11 inside can be cylindric, and its internal diameter is greater than the overall dimensions of the 3rd sleeve 9 outer wall, and the 3rd sleeve 9 is not contacted with the inwall of the 4th sleeve 11.
In the mode of execution that the utility model one is concrete, in order to outer sleeve being remained on mother nut 3, secondary nut 6, described outer sleeve is provided with shell fragment 14, and described mother nut 3 is or/and the outside of secondary nut 6 is provided with the draw-in groove 4 for snapping in shell fragment 14, with reference to figure 2, Fig. 4.In the mode of execution that the utility model one is concrete, shell fragment 14 is arranged on the bottom of the first sleeve 10, and it can be the shell fragment in similar L shape, and draw-in groove 4 can be arranged on the lower end of mother nut 3.In time penetrating outer sleeve, extrusion elastic 14 deforms, and after penetrating and putting in place, shell fragment 14 is resetted and snaps in the draw-in groove 4 of mother nut 3, thus being fixed on mother nut 3 by outer sleeve.Described shell fragment 14 is preferably provided with multiple, and the circumferencial direction along outer sleeve distributes.Further preferably, the notch 15 of inclination is provided with in the upper end of described mother nut 3; When shell fragment 14 to contact with this notch 15 and continues to decline time, shell fragment 14 more easily can be made to be out of shape, to be conducive to penetrating of outer sleeve.
The utility model is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, concerning the change of each mode of execution with to increase be apparent for one of ordinary skill in the art.Being intended that these changes all and increasing of claimant has all dropped in scope that the utility model claim protects.
