Abstract

The utility model discloses a steel bar connector and is characterized in that the steel bar connector comprises a sleeve, wherein the sleeve is in the shape of a cylinder substantially, the inner diameter and the outer diameter of the sleeve are gradually increased from the middle part to two ends, and the increase amplitude of the inner diameter is greater than that of the outer diameter; threads are arranged on the outer circumference of the sleeve, and the connector is provided with at least two lock nuts which are matched with the threads; through grooves are formed at two ends of the sleeve along the axial direction of a sleeve body; the connector further comprises two round table-shaped hollow wedge blocks which can be inserted from the two ends of the sleeve, the outer diameter of the small end of each wedge block is smaller than the inner diameter at the end part of the sleeve, and the outer diameter of the big end of each wedge block is larger than the inner diameter of the end part of the sleeve; and the wedge blocks are separated along the axial direction for forming two flap-shaped structures.

Description

A kind of reinforcing bar connector

Technical field:

The utility model relates to a kind of reinforcing bar connector.

Background technology:

In building, bridge, road construction process, reinforcing bar is one of the most frequently used material, and different application scenarios needs the reinforcing bar of different length, therefore for the use of reinforcing bar, usually needs to block, connect, present connection for reinforcing bar, the main mode that adopts welding or colligation, the construction cost of welding is higher, and needs outfit equipment and welder, and not allowing to produce the construction occasion of Mars at some, the mode of welding is inadvisable; Though the mode of steel wire lashing is simple, the exposed steel wire head in reinforcing bar junction is hurted sb.'s feelings easily, and topmost problem is, can not be with two reinforcing bar bindings point-blank.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of reinforcing bar connector, need not to adopt the form of welding two reinforcing bars can be linked together, and two reinforcing bars are on the same straight line.

The utility model technical solution problem adopts following technical scheme:

A kind of reinforcing bar connector is characterized in that having:

Internal diameter and the external diameter to two ends is gradual increase from the middle part for one roughly cylindrical circular sleeve, described sleeve, and the amplification of internal diameter is greater than the amplification of external diameter; The excircle of described sleeve is provided with screw thread, and described connector is provided with at least two locking nuts with described threaded engagement; The two ends of described sleeve axially offer one section groove along sleeve body; Described connector comprises that also the hollow of two truncated cone-shaped that can insert from described sleeve two ends carves piece, respectively carves the internal diameter of the external diameter of piece small end less than sleeve ends, carves the internal diameter of the external diameter of the big end of piece greater than sleeve ends; And respectively carve piece and separately form two lobe formula structures vertically.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

Adopt connector of the present utility model, two reinforcing bars securely can be linked together and on same straight line, this connector is easy to operation, with low cost, at the construction field (site) can be with getting with usefulness.

Description of drawings:

Fig. 1 is a structural representation of the present utility model; Sectional view when Fig. 2 uses for the utility model.

Number in the figure: 1 sleeve, 2 locking nuts, 3 grooves, 4 carve piece, 5 reinforcing bars.

Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

The specific embodiment:

Embodiment: in conjunction with Fig. 1, the present embodiment reinforcing bar connector has:

Internal diameter and the external diameter to two ends is gradual increase from the middle part for one roughly cylindrical circular sleeve 1, described sleeve, and the amplification of internal diameter is greater than the amplification of external diameter; The excircle of described sleeve is provided with screw thread, and described connector is provided with at least two locking nuts 2 with described threaded engagement; The two ends of described sleeve axially offer one section groove 3 along sleeve body;

Described connector comprises that also the hollow of two truncated cone-shaped that can insert from described sleeve two ends carves piece 4, respectively carves the internal diameter of the external diameter of piece small end less than sleeve ends, carves the internal diameter of the external diameter of the big end of piece greater than sleeve ends; And respectively carve piece and separately form two lobe formula structures vertically, in the processing, the endoporus of carving piece 4 should be complementary with the thickness of reinforcing bar, and the inclined-plane of carving the periphery of piece should be complementary with the formed inclined-plane of sleeve inner.

In the use, in conjunction with Fig. 2, two locking nuts 2 place the middle part of sleeve 1, two reinforcing bars 5 are inserted from the two ends of sleeve 1, carving piece 4 with two again inserts from the two ends of sleeve, carve between the inwall that piece is in the outer wall of reinforcing bar and sleeve, to the turn of the two ends of sleeve, can lock onto two locking nuts 2 with two reinforcing bars and be connected in the sleeve on the same straight line this moment.

Claims
