Abstract
The utility model belongs to the technical field of building element, specifically a lock female screw rod. The problem of traditional screw rod and nut cooperation during operation, the nut can be drawn suddenly and detain the screw rod that drops is solved, a lock female screw rod, includes the screw rod, and the screw rod both ends are equipped with the screw, and it has the nut to overlap on the screw, and the tip at screw rod both ends is equipped with along the radial toper round hole that sets up of screw rod, and it has the radial dilatation joint that sets up in a plurality of edges to incline in toper round hole week to open, is equipped with the toper screw in the toper round hole, and toper screw afterbody is opened there is the spill diaphragm orifice. The utility model discloses the screw rod passes the fixture during use, bring tighten nut into after, toper screw screw rod one end or both ends in is screwed up to the hexagon spanner in the reuse, makes screw rod one end or both ends screw head inflation blow, ensures that the nut is bearing hugely dragging power suddenly when exceeding the screw thread and bearing pressure, and the nut can not appear and draw the knot screw rod emergence major accident that drops suddenly.
Description
Technical field
The invention belongs to structural element technical field, specifically a kind of locknut screw rod.
Background technique
Screw is applied widely in actual life, when nut internal fixtion bearing material pressure exceedes thread line strength, just there will be a stroke button nut and fall phenomenon, and this phenomenon is also various accident root places, in order to avoid this accident to occur better, general people take to weld together to guarantee safety with electric weld handle nut and screw rod, cut open with oxygen welding when dismantling again, expensive effort inefficiency, and safety is not completely guaranteed yet.The present invention can effectively overcome above defect, screw rod is through fixture in use, after bringing nut screwing clamping into, screw rod one or both ends inner conical screw is tightened again with allen wrench, screw rod one or both ends screw head is expanded blow, guarantee nut to bear suddenly huge drag exceed screw thread bear pressure time, nut draw suddenly button landing time stop by thicker screw head large drag forces, and the drag that this screw rod can bear be screw thread bear the several times of drag, not there will be nut and draw suddenly the phenomenon of detaining the screw rod that comes off, the major accident occurred because nut draws button can be avoided completely.
Summary of the invention
When the utility model works to solve classic screw and nut screw connection, nut can be drawn suddenly button and to come off the problem of screw rod, provides a kind of locknut screw rod.
The utility model takes following technological scheme: a kind of locknut screw rod, comprise screw rod, screw rod two ends are provided with screw thread, on screw thread, cover has nut, the end at screw rod two ends is provided with the taper circular hole arranged along screw rod radial direction, taper circular hole week, side had some dilatation joints be disposed radially, and be provided with conical screw in taper circular hole, conical screw afterbody has spill plate hole.
Described spill plate hole is four prismatics or six prismatics.
During use, screw rod is through fixture, after bringing nut screwing clamping into, screw rod one or both ends inner conical screw is tightened again with allen wrench, screw rod one or both ends screw head is expanded blow, guarantee nut to bear suddenly huge drag exceed screw thread bear pressure time, and there will not be nut to draw suddenly button to come off screw rod generation major accident.
Compared with prior art, when the utility model uses, screw rod is through fixture, after bringing nut screwing clamping into, screw rod one or both ends inner conical screw is tightened again with allen wrench, screw rod one or both ends screw head is expanded blow, guarantee nut to bear suddenly huge drag exceed screw thread bear pressure time, and there will not be nut to draw suddenly button to come off screw rod generation major accident.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 partial enlarged drawing;
Fig. 3 is spill plate hole schematic diagram I;
Fig. 4 is spill plate hole schematic diagram II;
1-conical screw in figure, 2-taper circular hole, 3-dilatation joint, 4-nut, 5-screw rod, 6-spill plate hole.
Embodiment
As shown in Figure 1, 2, a kind of locknut screw rod, comprise screw rod 5, screw rod 5 two ends are provided with screw thread, on screw thread, cover has nut 4, and the end at screw rod 5 two ends is provided with the taper circular hole 2 arranged along screw rod radial direction, and taper circular hole 2 weeks sides have some dilatation joints 3 be disposed radially, be provided with conical screw 1 in taper circular hole 2, conical screw 1 afterbody has spill plate hole 6.
As shown in Figure 3,4, spill plate hole 6 is four prismatics or six prismatics.
During use, screw rod is through fixture, after bringing nut screwing clamping into, screw rod one or both ends inner conical screw is tightened again with allen wrench, screw rod one or both ends screw head is expanded blow, guarantee nut to bear suddenly huge drag exceed screw thread bear pressure time, and there will not be nut to draw suddenly button to come off screw rod generation major accident.
