Abstract
The utility model provides an anti-looseness bolt device. The bolt device comprises a bolt and a nut matched with the bolt, wherein the bolt comprises a bolt cap and a bolt rod; tooth-shaped corrugated grooves are formed on the working faces of the bolt cap and the nut; at least a pair of radial blind holes distributed in the axis direction are formed on the outer circumference of the bolt cap; and at least a pair of radial blind holes distributed in the axial direction of the threaded hole of the nut are formed on the outer circumference of the nut. The utility model has higher deformation resistance and slipping resistance, and can not be opened without a special wrench, thereby achieving good anti-theft performance and low missing possibility.
Description
Technical field:
The utility model relates to a kind of fastening piece, relates in particular to a kind of chek bolt device.
Background technique:
Present common chek bolt device, such as a word bolt, cross bolt or hex head bolt nut or the like, be provided with the tooth ripple groove at the working surface of the working surface of bolt or nut and can effectively prevent bolt or nut loosening, but 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, cause the unlatching or the locking of bolt all inconvenient, secondly, be used to open a word bolt, the instrument of cross bolt and hex head bolt nut is also comparatively extensive, an adjustable spanner almost can be opened the hex head bolt nut of all models, and the theftproof performance of bolt device is relatively poor.
The model utility content:
The technical problems to be solved in the utility model is that a kind of chek bolt device that abrasion deformation skids, theftproof performance is good that is difficult for is provided.
For solving above-mentioned technical problem, the utility model chek bolt device comprises bolt and the nut that matches with it, described bolt is made up of nuts and screw rod, the working surface of described nuts and nut is equipped with the tooth ripple groove, and the excircle of described nuts is provided with at least one pair of radial blind holes that distributes along axial direction; The excircle of described nut is provided with at least one pair of axial direction distribution radial blind holes along the tapped hole of nut.
As improvement, the radial blind holes on the described nuts is four pairs.
As further improvement, each on the described nuts evenly distributes to the excircle along nuts of blind hole radially.
As improvement, the radial blind holes on the described nut is four pairs.
As further improvement, each on the described nut evenly distributes to the excircle along nut of blind hole radially.
As improvement, described radial blind holes is the little cone shape hole of outer imperial palace.
After adopting said structure, the utlity model has following advantage:
Thereby wherein a pair of blind hole on locating stud inserting bolt cap on the special spanner or the bolt can be screwed the utility model chek bolt device is opened or locking, and the paired setting of radial blind holes and distribute along the axis of the axis of screw rod and tapped hole respectively and can make the spanner accurate positioning and be difficult for skidding, and on the nuts each evenly distributes to the excircle along nuts of blind hole radially, on the nut each evenly distributes along the nut excircle to blind hole radially, be convenient to like this open or the locking screw screw bolt and nut, spanner is when unlatching or locking screw screw bolt and nut, its active force is dispersed in the excircle of nuts and the excircle 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 chek bolt device uses special spanner to open, theftproof performance is good, is difficult for losing.

Embodiment:
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, the nut 2 that the utility model chek bolt device comprises bolt 1 and matches with it, described bolt 1 is made up of nuts 1.1 and screw rod 1.2, and the working surface of described nuts 1.2 and nut 2 is equipped with the tooth ripple groove, and described screw rod 1.2 is provided with partial thread.The excircle of described nuts 1.1 is provided with four pairs of radial blind holes 3 that distribute along screw rod 1.2 axial directions, described four pairs radially blind hole 3 along the excircle of nuts 1.1 evenly distribute be adjacent two couple radially the angle between the blind hole 3 be 90 degree.The excircle of described nut 2 also is provided with four pairs of radially blind holes 3, described every pair radially blind hole 3 distribute along the axial direction of tapped hole 2.1, described four pairs radially blind hole 3 evenly to distribute along the excircle of nut 2 be that angle between adjacent two pairs of blind holes 3 is 90 degree.Be to strengthen the theftproof performance of the utility model chek bolt device, the identical little cone shape hole of outer imperial palace that is of structure of the radial blind holes 3 on described nuts 1.1 and the nut 2.
According to general knowledge, bolt 1 and nut 2 need be furnished with a special spanner respectively during work, the locating stud inserting bolt 1 on the special spanner 4 (as shown in Figure 4) and the radial blind holes 3 on the nut 2 can be screwed bolt 1 and nut 2 is opened bolt device or locking then.
Screw thread in the utility model on the screw rod 1.2 also can be a Full Thread FT, and this variation is also in the protection domain of the utility model independent claims.
