The bolt device can limit the nut axially and has fine locking effect.
Description
Technical field
The utility model relates to technical field of fastening, particularly a kind of 12 jiaos of plum blossoms band pad screw bolt device.
Background technique
Bolt device is used widely as fastening piece, especially is applied to being connected and fixed of machinery.In order to allow equipment well connect, when fixing bolt, need consider to prevent that its generation is loosening.The common method that prevents bolt looseness generally is that the mode that adopts fasteners such as elastic washer, toothed washer or shell fragment to compress realizes, but in some special mechanical occasions, the bolt device that uses on the cantilever arrangement as crane, its vibration frequency is higher, vibration amplitude is big and bear certain lateral load, if can not prevent effectively that nut and screw rod from producing relative rotation, cantilever equipment can be because of the nut loosening of bolt device, come off and cause damage, has certain potential safety hazard.
The model utility content
Technical problem to be solved in the utility model is: providing a kind of can carry out 12 jiaos of good plum blossoms band pad screw bolt devices of axial limiting, anti-loosing effect to nut.
The technical scheme in the invention for solving the above technical problem is: a kind of 12 jiaos of plum blossoms band pad screw bolt device, comprise the bolt and the nut of screw-thread fit with it, and described bolt is provided with integrated bolt head and screw rod; It also comprises at least one jam nut, described bolt head and nut are the prism that cross section is 12 jiaos of plum blossom shapes, and the inner of described bolt head and nut is equipped with the clout body of integrated ring with it, and the axial length of the screw thread of described bolt equals the length of screw rod; The outer peripheral surface of described screw rod is provided with the locating slot that extends vertically, be used for the jam nut location, the size of described locating slot and the size of described jam nut match, the sidewall of described nut be provided with radially run through and with the positioning spiro pit of described jam nut screw-thread fit.
Compared with prior art, advantage of the present utility model is: the outer peripheral surface of the bolt shank of these 12 jiaos of plum blossom band pad screw bolt devices is provided with the locating slot that extends vertically, be used for the screw location, radially be provided with the tapped hole that cooperates with screw thread on the outer peripheral surface of nut, during use, nut is screwed on screw rod, determined the mounting point, then backing-up screw is screwed in the positioning spiro pit on nut, and jam nut is butted in the locating slot, is positioned by locating slot.Like this, though nut the vibration and lateral load under, jam nut also can carry out axial limiting to nut, thereby realizes the purpose of locking anticreep, its anti-loosing effect is better.
The quantity of described jam nut, locating slot and positioning spiro pit is two; The quantity of described jam nut, locating slot and positioning spiro pit is two; Described two locating slots are symmetricly set on the outer peripheral surface of screw rod vertically; Described two positioning spiro pits are symmetricly set on the sidewall of nut along axis.Like this, can be good at realizing axial limiting to nut, and stressed evenly, big influence can not arranged to the intensity of bolt.
Described locating slot is an opening slot, and described opening end is located at the end of screw rod away from bolt head.Like this, the processing of locating slot is convenient.
