Abstract
The utility model relates to a fastening screw bolt, which belongs to a threaded connecting element and comprises a screw bolt head and a threaded rod, wherein the screw bolt head and the threaded rod are connected into a whole, the threaded end of the threaded rod is provided with an opening groove, a threaded hole communicated with the opening groove is arranged on the threaded rod arranged at the upper side of the opening groove, and a screw capable of expending the opening groove is connected into the threaded hole. The fastening screw bolt has the advantage that when the fastening screw bolt is matched with an ordinary screw nut for locking parts, the loosening generated between the fastening screw bolt and the screw nut can be effectively prevented.
Description
Technical field:
The utility model relates to a kind of threaded connector, specifically is a kind of clamping bolt.
Background technique:
Bolt is used the effect that is connected fastening component of playing with nut usually; when using common screw bolt and nut to lock component; in order to prevent becoming flexible between the bolts and nuts; generally between nut and the component that are locked, fill up the upper spring packing ring; rely on the elastic force of spring washer to increase frictional force between the screw thread that bolts and nuts match; and then prevent loosening between the bolts and nuts; though this method can play effect locking between the bolts and nuts; but in actual application; it is not very desirable carrying out locking effect by pad upper spring packing ring, the phenomenon that often also can become flexible between the bolts and nuts.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of when being used with common nut, can effectively prevent and nut between loosening clamping bolt takes place.
Technical solution of the present utility model is, provide a kind of clamping bolt: comprise bolt head and threaded stem with following structure, bolt head and threaded stem connect into an integral body, wherein, the threaded end of threaded stem is provided with an opening slot, the threaded stem of opening slot upside is provided with a tapped hole that communicates with opening slot, is connected with a screw that opening slot can be strutted in the tapped hole.
Clamping bolt described in the utility model, wherein, opening slot can be by the axis of threaded stem, and tapped hole is perpendicular to opening slot.
Clamping bolt described in the utility model, wherein, screw can be headless screw, and its length is slightly less than half of screw thread path on the threaded stem.
After adopting above structure, compared with prior art, the utility model clamping bolt has the following advantages: different with common bolt, because the threaded end of the threaded stem of the utility model clamping bolt is provided with an opening slot, the threaded stem of opening slot upside is provided with a tapped hole that communicates with opening slot, be connected with a screw that opening slot can be strutted in the tapped hole, therefore, in use, after nut is tightened on the utility model clamping bolt, screw the screw of opening slot upside again, at this moment opening slot can be strutted by screw, the threaded stem of opening slot both sides is pressed on the nut, thereby can effectively prevents to take place between the utility model clamping bolt and the nut loosening.
Opening slot is by the axis of threaded stem, and tapped hole can make the intensity unanimity of the threaded stem of opening slot both sides perpendicular to opening slot, the threaded stem of opening slot both sides is opened simultaneously, thereby better be pressed on the nut.
Screw is a headless screw, and half the effect that its length is slightly less than screw thread path on the threaded stem is to go forward nut being spun on the utility model clamping bolt, need not just spin off directly precession to the screw of opening slot upside earlier, is convenient for people to use.
Description of drawings:
Fig. 1 is the three-dimensional decomposition texture schematic representation of the utility model clamping bolt;
Fig. 2 is the utility model clamping bolt and the nut structural representation when locking two component.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model clamping bolt is described further:
As depicted in figs. 1 and 2, in this embodiment, the utility model clamping bolt comprises bolt head 1 and threaded stem 2, bolt head 1 and threaded stem 2 connect into an integral body, the threaded end of threaded stem 2 is provided with an opening slot 3 by the axis of threaded stem 2, the threaded stem 2 of opening slot 3 upsides be provided with one with the opening slot 3 vertical tapped holes that communicate 4, be connected with a screw 5 that opening slot can be strutted in the tapped hole 4, screw 5 is a headless screw, and its length is slightly less than half of screw thread path on the threaded stem 2.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
