Abstract
The utility model discloses a self-tightened type connecting piece with right-hand threads and left-hand threads. The self-tightened type connecting piece comprises clamping sleeve nuts and a connecting screw barrel, a straight thread section and a taper hole section are arranged on each clamping sleeve nut, the connecting screw barrel is a hollow shaft piece with tapered chucks arranged at the two ends, a plurality of telescopic grooves are formed in the axial direction of the tapered chucks, and the telescopic grooves are distributed in the circumferences of the tapered chucks. One clamping sleeve nut is provided with the right-hand threads, the other clamping sleeve nut is provided with the left-hand threads, the connecting screw barrel is arranged between the two clamping sleeve nuts, external threads at the two ends of the connecting screw barrel are meshed with the internal threads of the clamping sleeve nuts respectively, and the tapered chucks at the two ends of the connecting screw barrel are in contact with the taper hole sections of the clamping sleeve nuts. The self-tightened type connecting piece has the advantages of being simple in structure, fast and convenient to connect and high in locking force and bearing capacity.
Description
Technical field
The utility model relates to connector technical field, especially docks a kind of from tightening up formula positive/negative thread connector of screw-thread steel pull bar.
Background technology
In construction engineering, especially at the cushion cap of speedway and high-speed railway, in the template installation of pier shaft, the employing reinforcing pull rod fixedly formwork way of steel form is conventional mode, the reinforcing pull rod of prior art adopts steel strand and round steel pull bar more, increase along with building volume, the supporting capacity of reinforcing pull rod and connection speed are all had higher requirement, due to finish rolling deformed bar, to have intensity high, skin friction resistance is large, be convenient to the advantage connecting, adopt finish rolling deformed bar to substitute traditional steel strand and round steel pull bar and become trend, for this reason, design that to be suitable for the connector of finish rolling deformed bar extremely urgent, prior art compression joint type, the connector of anti-tooth conic screw type, all there is the defect of bonding strength deficiency, trace it to its cause and be mainly that the coupling mechanism force between connector and indented bars is inadequate, restricted the development of Large Steel template formwork support process.
Utility model content
The purpose of this utility model is provide for the deficiencies in the prior art a kind of from tightening up formula positive/negative thread connector, the utlity model has simple in structure, connect quick and convenient, coupling mechanism force and the high advantage of supporting capacity.
The concrete technical scheme that realizes the utility model object is:
A kind of from tightening up formula positive/negative thread connector, its feature comprises cutting ferrule nut and connects barrel, the endoporus of described cutting ferrule nut is provided with straight thread section and taper hole section, its straight thread section is provided with the internal thread of dextrorotation or derotation, connecting barrel is the hollow shaft part that two ends are provided with conical chuck, outside being provided with in the middle part of on its outer wall, six sides, outer six side both sides are provided with the external screw thread of dextrorotation and derotation, the inner circle of its conical chuck is provided with thread groove, along several telescopic chute that is axially arranged with of conical chuck, telescopic chute is distributed on the circumference of conical chuck; Described cutting ferrule nut is each, dextrorotation and derotation screw thread, connect that barrel is located between two cutting ferrule nuts, the external screw thread at its two ends respectively with the internal thread engagement of cutting ferrule nut, and connect the conical chuck at barrel two ends and the taper hole section of cutting ferrule nut is touched.
The utlity model has simple in structure, connect quick and convenient, coupling mechanism force and the high advantage of supporting capacity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the lateral view that the utility model connects barrel;
Fig. 3 is use view of the present utility model.
The specific embodiment
Consult Fig. 1, Fig. 2, the utility model comprises cutting ferrule nut 1 and connects barrel 2, the endoporus of described cutting ferrule nut 1 is provided with straight thread section 11 and taper hole section 12, its straight thread section 11 is provided with the internal thread of dextrorotation or derotation, connect barrel 2 and be provided with the hollow shaft part of conical chuck 22 for two ends, outside being provided with in the middle part of on its outer wall, six sides 21, outer six side 21 both sides are provided with the external screw thread of dextrorotation and derotation, the inner circle of its conical chuck 22 is provided with thread groove 23, along several telescopic chute 24 that is axially arranged with of conical chuck 22, telescopic chute 24 is distributed on the circumference of conical chuck 22; Described cutting ferrule nut 1 is each, dextrorotation and derotation screw thread, connection barrel 2 is located between two cutting ferrule nuts 1, the external screw thread at its two ends meshes with the internal thread of cutting ferrule nut 1 respectively, and the conical chuck 22 at connection barrel 2 two ends touches with the taper hole section 12 of cutting ferrule nut 1.
The utility model is to use like this:
Consult Fig. 3, the termination of two screw-thread steels 4 that wish is connected is oppositely arranged, choosing is provided with each, the cutting ferrule nut 1 of dextrorotation and derotation internal thread, and one end that two cutting ferrule nuts 1 are provided with to taper hole section 12 is set on two screw-thread steels 4, by connecting barrel 2, be placed between the termination of two screw-thread steels 4, mobile cutting ferrule nut 1, make the internal thread and the external screw thread difference pre-engagement that is connected barrel 2 two ends of cutting ferrule nut 1, fix two cutting ferrule nuts 1, with spanner, be stuck on outer six sides 21 that connect barrel 2, turn and connect barrel 2, along with connecting barrel 2, further mesh with the cutting ferrule nut 1 that is provided with dextrorotation and derotation internal thread, now, the conical chuck 22 that connects barrel 2 two ends touches and is extruded with the taper hole section 12 of cutting ferrule nut 1, telescopic chute 24 extrusions of conical chuck 22, make conical chuck 22 towards the trend distortion of radially drawing in, thereby make thread groove 23 by screw-thread steel 4 lockings, finally realizing the utility model is connected with the quick and convenient of two screw-thread steels 4, have advantages of that coupling mechanism force and supporting capacity are high.
