Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to a kind of hexagonal belt pad partial thread bolt device.
Background technique
At present common bolt device comprises screw bolt and nut, is mainly used in and is fastenedly connected two parts that have through hole, at this moment only needs bolt passed behind the part to cooperate to tighten with nut to get final product.In some specific occasions, as needing certain circumferential running clearance between two parts, at this time nut and bolt need not to tighten fully, only need carry out axial limiting to two parts, and at this time Chang Gui bolts and nuts just can't be realized; Be subjected to situations such as vibrations or shake in addition, the nut that is screwed in like this on the bolt also can become flexible, even comes off, and causes two parts to be fixed, and locking property is poor.
The model utility content
The technical problems to be solved in the utility model is, a kind of can be to the fastened spacing and locking property of two part axials good hexagonal belt pad partial thread bolt device is provided.
The technical solution of the utility model is, a kind of hexagonal belt pad partial thread bolt device with following structure is provided, comprise bolt and the nut that matches with it, described bolt comprises hex head bolt head, the screw rod that is provided with screw thread and the polished rod that is provided with pad I, described nut is the hexagon nut of band pad II, the periphery wall of described screw rod is provided with a groove that extends vertically at least, described nut is provided with and runs through its sidewall and the quantity screw corresponding with groove, be combined with screw in the described screw, the end that described screw passes corresponding screw is entrenched in the corresponding groove.
After adopting above structure, the utility model compared with prior art has the following advantages: since described bolt comprise be provided with pad I hex head bolt head, the screw rod that is provided with screw thread and polished rod, described nut is the hexagon nut of band pad II, adopt hexagonal structure, versatility is better like this.The end that described screw passes corresponding screw is entrenched in the corresponding groove, between two parts, need certain circumferential running clearance like this, at this time nut and bolt need not to tighten fully, only nut need be screwed to certain position, by screw that nut is spacing in the position of needs again, can play fine axial limiting; And nut fixing after, can not be subjected to situations such as vibrations or shake, and become flexible or come off, can guarantee that two fastened parts are fixed, locking property is good.
As improvement, the quantity of described groove is two, and the quantity of corresponding screw and screw also is two, can better guarantee that like this nut is spacing on screw rod.
As further improvement, described two grooves are along screw rod circumference symmetry, and described screw is along the circumference symmetry of nut, like this guarantee nut spacing on screw rod in, also can guarantee the intensity of screw bolt and nut.
As further improvement, an end of described groove connects the end of screw rod, makes things convenient for the actual processing of groove like this.
Description of drawings
Accompanying drawing 1 is the structural representation of hexagonal belt pad partial thread bolt device of the present utility model.
Accompanying drawing 2 is the structural representation of the nut of hexagonal belt pad partial thread bolt device of the present utility model.
Accompanying drawing 3 is the left view of Fig. 1.
As shown in the figure: 1, bolt, 1.1, bolt head, 1.2, screw rod, 1.3, groove, 1.4, polished rod, 1.5, pad I, 2, nut, 2.1, screw, 2.2, pad II, 3, screw.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, hexagonal belt pad partial thread bolt device of the present utility model, the nut 2 that comprises bolt 1 and match with it, described bolt 1 comprises hex head bolt head 1.1, the screw rod 1.2 that is provided with screw thread and the polished rod 1.4 that is provided with pad I 1.5, and its order of connection is hex head bolt head 1.1, be provided with the screw rod 1.2 of screw thread, polished rod 1.4.Described pad I 1.5 is cylindrical, described nut 2 is the hexagon nut of band pad II, the periphery wall of described screw rod 1.2 is provided with a groove 1.3 that extends vertically at least, described nut 2 is provided with and runs through the corresponding screw 2.1 of its sidewall and quantity and groove 1.3, be combined with screw 3 in the described screw 2.1, the end that described screw 3 passes corresponding screw 2.1 is entrenched in the corresponding groove 1.3.
The quantity of described groove 1.3 is two, and the quantity of corresponding screw 2.1 and screw 3 also is two.
Described two grooves 1.3 are along screw rod 1.2 circumference symmetries, and described screw 2.1 is along the circumference symmetry of nut 2.
One end of described groove 1.3 connects the end of screw rod 1.2.The theoretical length of described groove 1.3 can not surpass the length of screw rod 1.2, and its physical length is with processing as required.
When tightening, bolt 1 passes two parts with holes earlier and nut 2 screws, and after grasping certain fastness, makes the screw 2.1 of nut 2 corresponding with groove 1.3 positions on the screw rod 1.2, again screw 3 is screwed in the screw 2.1, is embedded in the groove 1.3 up to the end face of screw 3.
When unclamping, twist earlier and send screw 3, make the end face of screw 3 leave groove 1.3, loose nut again.
