According to the taper sleeve locking type steel bar connecting joint, a locking structure that the outer sleeve is matched with the inner core connecting components is adopted, the use is very convenient, the unidirectional clamping or the reducing coupling can be realized, the assisting of any device is unnecessary, the welding is unnecessary, the hutching of threads is unnecessary, the operation can be finished by only manual screwing with hands, and the connection is firm without loosening; and stretching resistance experiments show that the strength of extension of the taper sleeve locking type steel bar connecting joint after being locked and connected far exceeds that of a welding structure.
Description
Technical field
The utility model belongs to the locking device of reinforcing bar, is specifically related to a kind of tapered sleeve locking type steel bar connector.
Background technology
At production fields such as buildings, often run into and to connect metal wire rod, for example in building operations, usually can run into interconnective problem between the reinforcing bar, generally adopt welding manner, the end of adjacent two reinforcing bars is welded and fixed together, need to use welding equipment during welding, the job site is subjected to the job site spatial constraints often in work high above the ground, use the welding equipment difficulty very large, have huge potential safety hazard, welding consumes mass energy, and environment is caused very large pollution; And the interface of welding is firm not, gets rusty easily, snaps.
In recent years, a kind of welded reinforcement linkage of exempting from occurred, this device is threaded connection, 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 equipment, still have potential safety hazard, in addition because reinforcing bar is longer, so the hitch screw thread is wasted time and energy, production efficiency is low, cost is high, has limited it and has applied.
The utility model content
The problems referred to above that exist in order to overcome the prior art field, the purpose of this utility model is, a kind of tapered sleeve locking type steel bar connector is provided, and has solved existing reinforcing steel bar connecting device and has had potential safety hazard, wastes time and energy, and has limited its problem of applying.
The tapered sleeve locking type steel bar connector that the utility model provides, it comprises outer sleeve, inner core connector, and the inner core connector is arranged in the outer sleeve, and described inner core connector is a pair of, the inner core connector comprises supporting seat, some locking members, and the supporting seat of a pair of inner core connector arranges back-to-back; Locking member comprises locking head, base end, and described base end is fastenedly connected on supporting seat, is provided with dashpot between adjacent two locking members.Described outer sleeve is the inner cone outer sleeve, and described inner cone outer sleeve comprises middle inner cone column casing and is symmetricly set on the interior flare nut at inner cone column casing two ends, adopts screw thread to spin between interior flare nut and the inner cone column casing.Described supporting seat is made by elastic engineering plastics, and supporting seat one end is the cone base, and the other end is the cylinder supporting seat, and described locking member is fastening to be arranged on the barrel of cylinder supporting seat.Described locking member is globoidal structure, the locking head of described locking member, and the inboard is provided with many fastening bands or groove.The base end of described locking member is provided with groove, and is fastenedly connected on the supporting seat of elastic plastic material by groove.Described locking member is provided with the 2-7 sheet.The inner cone column casing external surface of described inner cone outer sleeve, two ends external thread structure, mid portion are hexahedron structure or octahedral structure.
The tapered sleeve locking type steel bar connector that the utility model provides, its beneficial effect is, the locking mechanism that adopts outer sleeve to match with the inner core connector, very easy to use, can realize that one-sided clamping connection, two-side synchronous clamp the multiple connected modes such as connection, both sides reducing reinforcing bar connection, need to not exempt from welding, threading-less screw thread by any equipment, only need manually to close and to finish with hand-screw.And be connected firmly, non-loosening, the stretching resistance experiment shows that the tensile strength after being fastenedly connected is considerably beyond welded construction.
