Abstract
The utility model discloses a flange surface bolt fastening device, comprising a bolt (1) and a nut (2) which is fitted with the bolt (1) and provided with a flange surface; wherein the bolt (1) is composed of a bolt cap (1.1) and a screw stem (1.2) which is provided with flange surfaces. The flange surface bolt fastening device is characterized in that the external circumference of the bolt cap (1.1) is provided with at least two radial blind holes (3) distributed along the circumference, and the external circumference of the nut (2) is provided with at least two radial blind holes (4) distributed along the circumference. The flange surface bolt fastening device is not easy to wear, deform or skid, and has good antitheft performance.
Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to a kind of flanged surface bolt clamp device.
Background technique
Present common flanged surface bolt clamp device, such as a word bolt, cross bolt or hexagon flange bolt securing means 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 hexagon flange bolt securing means also is 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, the instrument of cross bolt and hexagon flange bolt securing means is also comparatively extensive, and one almost can open the hexagon flange bolt securing means of all models to adjustable spanner, and the theftproof performance of flanged surface bolt clamp device is relatively poor.
The model utility content
The technical problems to be solved in the utility model is that a kind of flanged surface bolt clamp device that abrasion deformation skids, theftproof performance is good that is difficult for is provided.
The technical solution of the utility model is, a kind of flanged surface bolt clamp device with following structure is provided, 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, 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, thereby can only can screw by wherein two blind holes on locating stud inserting bolt cap on the special spanner or the bolt the utility model flanged surface bolt clamp device is opened or locking.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 flanged surface bolt clamp device uses 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 the exploded perspective view of flanged surface bolt clamp device of the present utility model.
Accompanying drawing 2 is the schematic representation after flanged surface bolt clamp device of the present utility model cooperates;
Accompanying drawing 4 is the structural representation of the utility model flanged surface bolt clamp device special spanner.
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, flanged surface bolt clamp device of the present utility model, 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, 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.
