Abstract
The utility model relates to a prestressing force steel nail which comprises a screw cap and a threaded rod, wherein a single slot is formed on the screw cap, the junction of the threaded rod and the screw cap is provided with a slotted hole, and the lower end of the threaded rod on which at least ten oblique thread slots are formed is tapered. The prestressing force steel nail matched with a steel wire solves the problem of disintegration caused by the traditional steel nail used for fixing a broken object; furthermore, the prestressing force steel nail has the advantages of high firmness, simple operation and easy popularization and application.
Description
The utility model relates to a kind of steel wire nail, especially a kind of reinforcement of wire nail that is used for fixing fracture material.
Traditional steel wire nail is used for fixing fracture material first tie wire on fracture material often, fixes with steel nail then, can not occur fracture material generally speaking and burst apart or tie up the phenomenon that disconnected body does not connect after the stickfast.But, because the unfixing relation that links to each other between steel wire and the screw, thereby fracture place not firm, object also can occur tying up and connect situation about differing.
The purpose of this utility model is to provide a kind of reinforcement of wire nail, and it and steel wire are used, and reach to reinforce fracture material fully and make fracture place of fracture material be combined into holistic effect.
The purpose of this utility model is achieved in that a kind of reinforcement of wire nail, it comprises nut (1), screw rod (2), it is characterized in that nut (1) and screw rod (2) are an integral body, nut (1) is hexagon, its top is provided with one single groove (3), screw rod (2) and nut (1) junction are provided with a Chang Yuan hole (4) along centerline direction, and the lower end of screw rod (2) is pointed for awl, are provided with the oblique thread groove (5) that is no less than 10 roads in the upper end of screw rod (2) with boring between the tip.When using the reinforcement of wire nail, the steel wire nail is screwed in about surplus approximately 2 circles of fracture material earlier.The butt end of fracture material is drawn close, then 2 circles are twined to the Chang Yuan hole passing steel wire and nail on and in a side of fracture material in two of steel wire, the progressive afterwards steel wire nail that screws, thus along with the precession of steel nail, steel wire is that full from coil to coil is wrapped on the fracture material, and the silk head of steel wire also can be imbedded under the nut of steel nail.
Owing to adopt such scheme, offered the Chang Yuan hole of wearing at the root of reinforcement of wire nail around steel wire, and thereby improved the fixedly solid not firm problem of fracture material of traditional steel wire nail, also widened the suitable application area that steel wire is followed closely simultaneously.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is the fundamental diagram that is used for fixing fracture material of the present utility model;
Among the figure: the 1-nut; The 2-screw rod; The single groove of 3-; 4-Chang Yuan hole; The oblique thread groove of 5-; The 6-steel wire; The 7-fracture material.
It comprises by Fig. 1,2 the utility model: nut 1, screw rod 2, it is characterized in that nut 1 and screw rod 2 are an integral body, nut 1 is hexagon, its top is provided with single groove 3 one, screw rod 2 is provided with a Chang Yuan hole 4 with nut 1 junction along centerline direction, the lower end of screw rod 2 is pointed for awl, is provided with the oblique thread groove 5 that is no less than 10 roads in the upper end of screw rod 2 with boring between the tip.Chang Yuan hole 4 on the described screw rod 2 can the steel wire 7 of while two ends of cross-under to passing this hole in its hole.When the affixed fracture material of needs, to prop up such as single groove 3 of screw-driver or precession device aligning nut 1 and with it earlier, vertically rotate into fracture material and slightly surplus two circles oblique cap thread groove 5 then on the right side, this moment with the two ends of steel wire 6 to passing the Chang Yuan hole 4 on the screw rod 2, and general's end wherein is wrapped in an end of the joint of fracture material 7, afterwards screw rod 2 being continued to screw in fracture material twines on the joint of fracture material 7 fully until steel wire, the termination of steel wire 7 can be imbedded under the nut, thereby finishes the work of fixedly connected fracture material.
Claims (2)
1, a kind of reinforcement of wire nail, it comprises nut (1), screw rod (2), it is characterized in that nut (1) and screw rod (2) are an integral body, nut (1) is hexagon, its top is provided with one single groove (3), screw rod (2) and nut (1) junction are provided with a Chang Yuan hole (4) along centerline direction, and the lower end of screw rod (2) is pointed for awl, are provided with the oblique thread groove (5) that is no less than 10 roads in the upper end of screw rod (2) with boring between the tip.
2, reinforcement of wire nail according to claim 1 is characterized in that the Chang Yuan hole (4) on the described screw rod (2), can the steel wire (7) of while two ends of cross-under to passing this hole in its hole.
