Abstract
The utility model discloses a half thread bolt device which comprises a bolt (1) and a nut (2) matched with the bolt, wherein the bolt (1) consists of a bolt head (1.1), a full thread screw rod (1.2) and a polish rod (1.3), wherein the bolt head (1.1) is provided with two through holes (1.1.1) penetrating along the radial direction. The half thread bolt device is not easy to slip due to wear and deformation.
Description
Technical field
The utility model relates to fastening piece, relates in particular to a kind of partial thread bolt device.
Background technique
Present common bolt device, such as a word bolt, cross bolt or hex head bolt or the like, in use there is following shortcoming: at first, the force position of bolt head is few, and after repeatedly using, a 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, and causes the unlatching of bolt or locking all inconvenient.
The model utility content
The technical problems to be solved in the utility model is that a kind of partial thread bolt device that is difficult for abrasion deformation and skids is provided.
The technical solution of the utility model is, a kind of partial thread bolt device with following structure is provided, and comprises bolt and the nut that matches with it, and described bolt is made up of bolt head, full flight screw and polished rod, and described bolt head is provided with a through hole that radially runs through.
Described bolt head is the hex head bolt head.
Described bolt head is the hexagon socket head cap screw head.
After adopting above structure, the utility model compared with prior art, have the following advantages: because described bolt head is provided with a through hole that radially runs through, bolt head promptly can adopt conventional spanner to open or tighten like this, also can adopt prevailing strip instrument to insert in the through hole, utilize lever principle to come swivel bolt, be difficult for abrasion deformation like this and skid.
