Abstract
The utility model discloses a connection device of a metal wire, which is characterized by comprising an outer sleeve and an inner core connecting piece, wherein the inner core connecting piece is sleeved in the outer sleeve, the two ends of the inner wall of the outer sleeve are circular conical surfaces, and the middle is a cylindrical surface; the inner core connecting piece comprises a supporting piece and locking pieces, and the supporting piece is a cylindrical structure with grooves on two end surfaces; the longitudinal section of the supporting piece is in an I shape, and locking grooves are arranged on lug bosses forming the grooves; the locking pieces are inserted in the locking grooves, and the outer sleeve comprises a part A and a part B which are mutually and rotatably connected; and the part A is provided with internal threads, and the part B is provided with external threads. With the locking structure that the outer sleeve is matched with the inner core connecting piece, the connection device is very convenient to use, does not use any equipment, is free of welding and hitch threads, and only needs to screw with the hand.
Description
Technical field
The utility model relates to a kind of metal wire rod connection set.
Background technique
At production fields such as buildings, often run into and to connect metal wire rod, for example in construction, usually can run into interconnective problem between the reinforcing bar, generally adopt welding manner, the end of adjacent two reinforcing bars is weldingly fixed on together, need use welding equipment during welding, the job site is subjected to the job site spatial constraints often in high-lift operation, use the welding equipment difficulty very big, have huge potential safety hazard, welding consumes a large amount of energy, and environment is caused very big pollution; And the jointing of welding is firm inadequately, gets rusty easily, snaps.
In recent years, a kind of welded reinforcement connection set of exempting from occurred, this device is by being threaded, with adjacent two end reinforced hitch screw threads, by long nut two ends are connected, the mode complex process that is threaded needs prior or on-the-spot hitch screw thread, use reinforcing bar hitch screw thread special device, still have potential safety hazard, in addition because reinforcing bar is longer, so the hitch screw thread is wasted time and energy, manufacturing efficiency is low, cost is high, has limited it and has applied.
Summary of the invention
In order to solve the problems referred to above that the prior art field exists, the purpose of this utility model is, a kind of metal wire rod connection set is provided, and is simple in structure, reasonable in design, easy to use, efficient height, energy-conserving and environment-protective.
The metal wire rod connection set that the utility model provides, comprise outer sleeve, inner core link, described inner core link is sleeved in the outer sleeve, described outer sleeve inwall, two ends are conical surface, and the centre is the cylndrical surface, and the tapering of described conical surface is the 20-30 degree, this outer sleeve comprises A, the B two-part that spin mutually, and A partly is provided with internal thread, B and partly is provided with outside nut.The aperture, two ends of described outer sleeve is a bit larger tham the external diameter of the linear metal material that need to connect.
Described inner core link comprises supporting element, locking element, and described supporting element is the cylindrical structure that both ends of the surface are provided with groove, and its longitudinal section is " worker " font, is provided with locking slot on the described boss that surrounds groove, and described locking element is inserted knot in locking slot.
Described supporting element is made by having certain flexible rigid material, as duroplasts.The internal diameter of described supporting element two ends groove is identical with outer sleeve two ends aperture size.
Described locking slot is identical with the quantity of locking element, for 3-5, forms a circle around groove.
Described locking element inboard is provided with some bands or groove.
The metal wire rod connection set that the utility model provides, its beneficial effect are, the locking mechanism that adopts outer sleeve to match with the inner core link, very easy to use, need not exempt from welding, threading-less screw thread, only need manually to close and to finish with hand-screw by any equipment.And be connected firmly, non-loosening, the stretching resistance experiment shows that the tensile strength after being fastenedly connected is considerably beyond welded structure.
Description of drawings
Fig. 1 is an embodiment's of the utility model an overall structure schematic representation;
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
Mark among the figure:
1. outer sleeve; 2. supporting element; 3. locking element; 4. groove; 5. reinforcing bar; 6. conical surface, 7. boss; 8. locking slot.
Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the metal wire rod connection set that the utility model is provided is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the metal wire rod connection set of present embodiment, be the link that is used for the Twisted Steel that construction generally uses, it comprises outer sleeve 1, inner core link, and described inner core link is sleeved in the outer sleeve 1, described outer sleeve inwall, two ends are conical surface, and the centre is the cylndrical surface, and the tapering of described conical surface 6 is 25 degree, this outer sleeve comprises A, the B two-part that spin mutually, and A partly is provided with internal thread, B and partly is provided with outside nut.The aperture, two ends of described outer sleeve is a bit larger tham the end reinforced external diameter that needs connection.
Described inner core link comprises supporting element 2, locking element 3, described supporting element 2 is provided with the cylindrical structure of groove 4 for both ends of the surface, its longitudinal section is " worker " font, is provided with locking slot 8 on the described boss 7 that surrounds groove, and described locking element 3 is inserted knot in this locking slot 8.
Described supporting element 2 is made by having certain elasticity duroplasts.The internal diameter of described supporting element two ends groove 4 is identical with the aperture size at outer sleeve 1 two ends.Described locking slot is identical with the quantity of locking element, is 3, forms a circle around groove.Described locking element 3 inboards are provided with some bands.
During connecting reinforcement, unscrew outer sleeve, the aperture, two ends that the end of two reinforcing bars 5 that needs are connected is inserted this connection set respectively, the end of reinforcing bar 5 is entered in the groove 4 of inner core link, screw outer sleeve then, this moment, the conical surface of outer sleeve inboard compressed locking element 3, and reinforcing bar 5 is fastenedly connected, the band of locking element inboard increases the frictional force between locking element and the Twisted Steel, makes locking more fastening.
