Abstract
The invention discloses a bolt clamp device and a special spanner. The bolt clamp device comprises a bolt (1) and a nut (2), wherein the bolt (1) consists of a bolt cap (1.1) and a screw (1.2); the outer circumference of the bolt cap (1.1) is provided with at least two radial blind holes (3); and the outer circumference of the nut (2) is provided with at least two radial blind holes (3). The bolt clamp device is not easy to wear, deform and skid and has good anti-theft performance. The special spanner comprises a handle (4) and a spanner head (5), wherein the spanner head (5) is shaped like an arch which is matched with the outer circumference of the bolt cap (1.1) or the nut (2), and the inner wall of the spanner head (5) is provided with two locating pins (5.1) matched with the blind holes (3). When the spanner is used for unscrewing or screwing up the bolt and the nut, the acting force of the spanner is dispersed at the outer circumferential surfaces of the bolt cap and the nut and the acting force of the locating pins to the radial blind holes is smaller, so the radial blind holes are not easy to wear and deform.
Description
Technical field
The present invention relates to a kind of fastening piece and special tool, relate in particular to a kind of bolt clamp device and special spanner.
Background technique
Present common bolt and nut, such as a word bolt, cross bolt or hex head bolt 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 hex head bolt nut also is the same, after using for a long time or repeatedly, the also easy abrasion deformation of its nuts skids, even use special spanner also to be difficult to its unlatching or locking, secondly, a common word bolt, the opener of cross bolt and hex head bolt nut is also comparatively extensive, and one almost can open the hex head bolt nut of all models to common adjustable spanner, and the theftproof performance of this bolt and nut is relatively poor.
Summary of the invention
The technical problem to be solved in the present invention is that a kind of bolt clamp device that abrasion deformation skids, theftproof performance is good that is difficult for is provided.
Technological scheme of the present invention is, a kind of bolt clamp device with following structure is provided, and comprises bolt and the nut that matches with it, and described bolt is made up of nuts 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.
Another technical problem that the present invention will solve is, a kind of special spanner that is used for above-mentioned bolt clamp device is provided, comprise handle and driving end, described driving end be shaped as the arc that the excircle with the excircle of screw cap or nut matches, the inwall of described driving end is provided with two locating studs that match with radial blind holes.
After adopting above structure, the present invention compared with prior art has following remarkable advantage and has a mind to effect: 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 bolt and nut of the present invention 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 present invention 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 for invention the exploded perspective view of bolt clamp device.
Accompanying drawing 2 is the schematic representation after bolt clamp device of the present invention cooperates;
Accompanying drawing 4 is the structural representation of the special spanner of bolt clamp device of the present invention.
As shown in the figure: 1, bolt, 1.1, nuts, 1.2, screw rod, 2, nut, 3, radial blind holes, 4, handle; 5, driving end; 5.1, locating stud.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, bolt clamp device of the present invention, the nut 2 that comprises bolt 1 and match with it, described bolt 1 is made up of nuts 1.1 and screw rod 1.2, 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.
According to general knowledge, bolt 1 and nut 2 need be furnished with a special spanner respectively during work, with the radial blind holes 3 on 5.1 inserting bolts 1 of the locating stud on the special spanner and the nut 2, the excircle that the driving end 5 of arc encases the excircle of nuts 1.1 and nut 2 can screw bolt 1 and nut 2 is opened bolt clamp device of the present invention or locking then.
