Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technological scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Fig. 1 is the generalized section of anti-theft nut component under assembled state of the embodiment of the invention.As shown in Figure 1, anti-theft nut component comprises nut sleeve 1, special-shaped nut 2 (being non-standard nut) and bolt 3.Nut sleeve 1 comprises cylinder 11, and the upper end of cylinder 11 comprises reducing 12, and nut sleeve 1 can be rotatably set in outside the special-shaped nut 2.The upper end of special-shaped nut 2 is located in the nut sleeve 2 by the reducing 12 of nut sleeve 1 with block, and the lower end of special-shaped nut 2 has polyhedron 21, and special-shaped nut 2 vertically is provided with tapped hole 22.Bolt 3 is threadedly connected in the tapped hole 22 of special-shaped nut 2, and the head of bolt 3 has a recess 31 (cooperation Fig. 2-shown in Figure 4).
Fig. 5 and Fig. 6 are that the master of special spanner of the anti-theft nut component of the embodiment of the invention looks partial cutaway schematic representation and schematic side view.Like Fig. 5, shown in 6, special spanner comprises bar 4, and the two ends of bar 4 are respectively sleeve 5 and convex body 6; Convex body 6 matches with the recess 31 of bolt 3; Match with the polyhedron 21 of special-shaped nut 2 in the inside of sleeve 5, outside being arranged on rotationally in the cylinder 11 of nut sleeve 1 that is to say that sleeve 5 can not drive nut sleeve 1 and rotate together when rotating.
In the anti-theft nut component of the embodiment of the invention; Because nut sleeve 2 rotatably is coated on special-shaped nut 2 in it, and the lower end of special-shaped nut 2 has polyhedron 21, so has only the sleeve 5 when one of them special spanner to stretch in the nut sleeve 2; The lower end of the sheathed special-shaped nut 2 in the inside of sleeve 5; After the convex body 6 of another special spanner blocks the recess of bolt 3, special-shaped nut 2 is rotated relatively with bolt 3, for example make the special spanner location of blocking bolt 3 of top motionless; The special spanner of the sheathed special-shaped nut 2 of below is rotated: when the two screws action; Can parts such as solar panels be arranged between special-shaped nut 2 and the nut bolt 3, to avoid solar panels etc. stolen, theftproof performance is good; When the two unscrews action, can parts such as solar panels be carried out demolition and maintenance.
In the embodiment of the invention, the reducing 12 of nut sleeve 1 is cone, and the upper end of special-shaped nut 2 is a cone 23, and reducing 12 matches with cone 23, so that special-shaped nut 2 is limited in the cylinder 11 of nut sleeve 1, avoids its upper end from nut sleeve 1 to deviate from.Wherein, cone can be cone, and cylinder 11 can be cylinder-like body, and cone 23 can be coniform body, so be convenient to processing, and more convenient nut sleeve 1 is rotated outside special-shaped nut 2; In addition, the cross section of cone, cylinder 11 and cone 23 is except circle, and also can be to influence the polygonal of nut sleeve 1 in special-shaped nut 2 inner rotary.
In the embodiment of the invention; The height of the cylinder 11 of nut sleeve 1 can be greater than the height of special-shaped nut 2; Special-shaped nut 2 entirely is located in the nut sleeve 1; Except special spanner, use other instrument can't or to be not easy, and then help improving theftproof performance special-shaped nut 2 location or rotation.
And the height of the cone of nut sleeve 1 upper end can be slightly less than the height of the cone 23 of special-shaped nut 2 upper ends; So be in when being locked state when special-shaped nut 2; Nut sleeve 1 and the state of bolt 3 have been avoided with the clamping of parts such as solar panels; But special-shaped nut 2 and bolt 3 be clampings such as solar panels, thereby make nut sleeve 1 still can freely rotate, and further improves theftproof performance.
In the embodiment of the invention; The polyhedron 21 of special-shaped nut 2 lower ends can be irregular polyhedrons; Wherein the cross section of irregular polyhedrons can be made up of straight flange and circular arc limit; So make special spanner be not easy, must make that special spanner could be with polyhedron 21 location or the rotation of special-shaped nut 2 by imitated.
The lower head of bolt 3 is provided with packing ring, and for example bullet pad 32 and plain cushion 33 so make things convenient for bolt 3 and special-shaped nut 2 that parts such as solar panels are clamped.Wherein, bolt 3 can be head for special-shaped T40, also can be other suitable bolt.
In the embodiment of the invention, the sleeve 5 of special spanner and the axis of convex body 6 are all perpendicular with the axis of bar 4.So make in the limited installing space of the upper and lower of solar panels, also can the sleeve 5 of special spanner be stretched in the cylinder 11 of nut sleeve 1, and can easily convex body 6 be established in the recess of bolt 3, can accomplish fastening and dismounting action easily.
The above is merely several embodiments of the present invention, and those skilled in the art can carry out various changes or modification to the embodiment of the invention and do not break away from the spirit and scope of the present invention according to application documents are disclosed.
