Description
Technical field
The utility model relates to a kind of bolt device, relates to a kind of ten jiaos of plum blossom band pad partial thread bolt devices that are mainly used on the lax mobile machine or rather.
Background technique
Bolt device is a kind of common fastening piece, and it mainly utilizes, and screw thread on the screw rod and screw head are realized unidirectionally tightening, and tight etc. being fastenedly connected.Bolt device comprises bolt and nut; nut screws on screw rod during use; but we run into because extraneous factors such as vibration cause the problem of the screw rod and the nut matching loose of bolt device through regular meeting in daily life; screw rod and nut in case loosening just can't fastening object, this will bring puzzlement to people's life.
The model utility content
The technical problems to be solved in the utility model is that a kind of ten jiaos of plum blossom band pad partial thread bolt devices with locking effect are provided.
Technical solution of the present utility model is, a kind of ten jiaos of plum blossoms band pad partial thread bolt devices with following structure are provided, and it comprises bolt and nut, and described bolt has integrated screw rod and screw head, and it also comprises positioning screwn; Described screw rod excircle is provided with the locating slot that at least one extends vertically, described nut is provided with the radial screw bore that quantity equates with the quantity of described locating slot, described nut screws on described screw rod, described positioning screwn can screw in radial screw bore, and the end face of described positioning screwn can support to described locating slot; Described screw head is ten jiaos of plum blossom shape bodies and has ring pad integrated with it; Described nut is ten jiaos of plum blossom shape bodies and has ring pad integrated with it; Described screw rod is provided with the outside thread that extends along screw axial from the screw rod free end, and described externally threaded axial length equals 2/3rds of described spiro rod length at the most.
After adopting above structure, ten jiaos of plum blossom bands of the utility model pad partial thread bolt device compared with prior art has the following advantages:
Because described screw rod excircle is provided with the locating slot that at least one extends vertically, described nut is provided with the radial screw bore that quantity equates with the quantity of described locating slot, during use, described nut screws on described screw rod, described positioning screwn screws in radial screw bore and the end face of positioning screwn supports to described locating slot, can be by positioning screwn with the nut axially locating, make the locking effect that the utlity model has.
As a kind of improvement of the present utility model, described locating slot axially connects the free end of described screw rod and the axial length of described locating slot and equals described externally threaded axial length.Because it is described locating slot axially connects the free end of described screw rod, more convenient when making the processing locating slot.
As another kind of improvement the of the present utility model, described locating slot is two, described two locating slots are located on the excircle of described screw rod symmetrically, with its accordingly, described radial screw bore is that two and these two radial screw bore are located on the described nut symmetrically, and described positioning screwn is two.A locating slot is set on described screw rod, and in the process of using, nut is understood unbalance stress and is tilted, thereby influences the using effect of bolt device; And the intensity that more locating slot can reduce screw rod is set on described screw rod, thus also can influence the using effect of bolt device, therefore, it is optimum implementation that two locating slots are set on described screw rod.
Also have a kind of improvement as of the present utility model, described positioning screwn is a ladder-type, and the big end of described positioning screwn is provided with screw thread, and described big end can screw in radial screw bore, and the end face of the small end of positioning screwn can support to described locating slot.The width of described locating slot matches with the diameter of described positioning screwn small end.The axial length of described positioning screwn small end is greater than the degree of depth of described locating slot.Because positioning screwn is a ladder-type, big end can screw in radial screw bore, small end can be positioned at described locating slot, so just the width of the locating slot on the screw rod can be in the fastening strength that does not influence between positioning screwn and the nut, can reduced, thereby the intensity of screw rod can be guaranteed more.
