Abstract
The utility model discloses a fastening device for a toothed bolt on a flange surface, comprising a bolt (1) and a nut (2) on the flange surface matched with the bolt. The bolt (1) comprises a bolt cap (1.1) and a screw rod (1.2) which are provided with the flange surface. The flange surfaces on the nut (2) and the bolt cap (1.1) are both provided with a toothed wavy slot. The fastening device is characterized in that at least two radial blind holes (3) along the circumferential direction are arranged on the periphery of the bolt cap (1.1); and at least two radial blind holes (4) along the circumferential direction are arranged on the periphery of the nut (2). The fastening device for the toothed bolt on a flange surface is not easy to wear and deform and slip, and has good theft proofness.
Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to a kind of flange and wears the tooth bolt clamp device.
Background technique
Common flange is worn the tooth bolt and nut at present, such as a word bolt, cross bolt or hexagonal flange are worn tooth bolt and nut or the like, in use there is following shortcoming: at first, the force position of nuts is few, after repeatedly using, one word groove or the easy abrasion deformation of cross recess skid, and the hexagonal flange to wear the tooth bolt device also be the same, after using for a long time or repeatedly, the also easy abrasion deformation of its nuts skids, cause the unlatching or the locking of bolt all inconvenient, secondly, be used to open a word bolt, it is also comparatively extensive that cross bolt and hexagonal flange are worn the instrument of tooth bolt device, and the hexagonal flange that almost can open all models to adjustable spanner is worn the tooth bolt and nut, and it is relatively poor that flange is worn the theftproof performance of tooth bolt and nut.
The model utility content
The technical problems to be solved in the utility model is, provides a kind of and is difficult for the flange that abrasion deformation skids, theftproof performance is good and wears the tooth bolt clamp device.
The technical solution of the utility model is, provide a kind of flange to wear the tooth bolt clamp device with following structure, comprise bolt and match with it and be provided with the nut of flanged surface, described bolt is made up of nuts that is provided with flanged surface and screw rod, flanged surface and the flanged surface on the nuts on the described nut are equipped with the tooth ripple groove, and the excircle of described nuts is provided with at least two circumferential radial blind holes; The excircle of described nut is provided with at least two circumferential radial blind holes.
After adopting above structure, the utility model compared with prior art has the following advantages: because the excircle of described nuts is provided with at least two circumferential radial blind holes; The excircle of described nut is provided with at least two circumferential radial blind holes, the utility model flange is worn the tooth bolt device is opened or locking thereby can only can screw by wherein two blind holes on locating stud inserting bolt cap on the special spanner or the bolt.Spanner is when unlatching or locking screw screw bolt and nut, its active force is dispersed in the outer peripheral surface of nuts and the outer peripheral surface of nut, locating stud is less to the active force of blind hole radially, radial blind holes is difficult for abrasion deformation, thereby make stronger resistance to deformation of having of screw bolt and nut and the anti-ability of skidding, in addition, the utility model flange is worn the tooth bolt device and is used special spanner to open, theftproof performance is good, is difficult for losing.
As improvement, the radial blind holes quantity of described nuts is at least three, makes things convenient for special spanner to select a plurality of angles to screw.
As further improvement, on the described nuts adjacent every pair radially the arc length between the blind hole equate that two blind holes that make things convenient for special spanner can choose at random are wherein screwed.
As improvement, the radial blind holes quantity of described nut is at least three, makes things convenient for special spanner to select a plurality of angles to screw.
As further improvement, on the described nut adjacent every pair radially the arc length between the blind hole equate.Two blind holes that make things convenient for special spanner can choose at random are wherein screwed.
As improvement, described radial blind holes is the little cone shape hole of outer imperial palace, skids when strip class instrument is inserted, and theftproof performance is better.
Description of drawings
Accompanying drawing 1 is worn the exploded perspective view of tooth bolt clamp device for flange of the present utility model.
Accompanying drawing 2 is that flange of the present utility model is worn the schematic representation after the tooth bolt clamp device cooperates;
Accompanying drawing 4 is worn the structural representation of tooth bolt clamp device special spanner for the utility model flange.
As shown in the figure: 1, bolt, 1.1, nuts, 1.2, screw rod, 2, nut, 3, radial blind holes, 4, radial blind holes, 5, spanner, 5.1, locating stud.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, flange of the present utility model is worn the tooth bolt clamp device, comprise bolt 1 and match with it and be provided with the nut 2 of flanged surface, described bolt 1 is made up of nuts 1.1 that is provided with flanged surface and screw rod 1.2, flanged surface on the described nut 2 and the flanged surface on the nuts 1.1 are equipped with the tooth ripple groove, described screw rod 1.2 can be provided with partial thread or Full Thread FT, and the excircle of described nuts 1.1 is provided with at least two circumferential radial blind holes 3; Radial blind holes 3 quantity of present embodiment are four, and described radial blind holes 3 evenly distributes along nuts 1.1 circumference, on the promptly described nuts 1.1 adjacent every pair radially the arc length between the blind hole 3 equate and be 90 degree.The excircle of described nut 2 is provided with at least two circumferential radial blind holes 4, present embodiment radial blind holes 4 quantity are at least four, described radial blind holes 4 evenly distributes along nut 2 circumference, on the promptly described nut 2 adjacent every pair radially the arc length between the blind hole 4 equate and be 90 degree.
Described radial blind holes 3 and radial blind holes 4 are the little cone shape hole of outer imperial palace.
As shown in Figure 4, thus the radial blind holes 3 of 5.1 inserting bolts 1 of the locating stud on the special spanner 5 or the radial blind holes 4 on the nut 2 can be screwed bolt 1 or nut 2 with its unlatching or locking.
