Although formula can solve inconvenience brought by welding manner, but it there are problems that being not connected firmly to bar reinforcement.Therefore, such as
What solves above-mentioned technical problem, it has also become technical problem urgently to be resolved.
Utility model content
The utility model provides a kind of connector of connection screw thread reinforcing bar, with easy for construction, the advantages of being connected firmly,
Solves the above-mentioned connection unstable technical problem of reinforcing bar in the prior art.
In order to solve the above technical problems, a kind of technical solution provided by the utility model is: providing a kind of connection screw thread
The connector of reinforcing bar is connected to first screw set and the second screw set at the hollow shaft both ends including hollow shaft, rotation；It is described
Hollow shaft is by elastomeric layer and is wrapped in the metal layer of the elastomeric layer outer ring and forms.
The utility model is by adopting the above-described technical solution, when in the first screw set and the second screw set precession hollow shaft
When, tighten hollow shaft, after the elastomeric layer of hollow shaft inner ring is under pressure, two spirals will being arranged in hollow shaft
Tightening, it is easy for construction.
Further, the inner wall of the hollow shaft is provided with anti-skidding pawl；Anti-skidding pawl increases inner wall of hollow shaft and spiral shell
The friction of line reinforcing bar outer surface improves fastness.
Further, the surface of the hollow shaft along axial direction be evenly equipped with cross rib hole and it is axially spaced longitudinal rib hole is distributed with,
The cross rib of the cross rib hole and screw-thread steel matches, and the longitudinal rib of the longitudinal rib hole and screw-thread steel matches.By cross rib hole and indulge
Rib holes is mutually engaged with the cross rib of screw-thread steel and longitudinal rib respectively, so that the inner sidewall of hollow shaft and being bonded for screw-thread steel are closer, is mentioned
High bonding strength.
Further, the elastomeric layer is made of rubber ring；Rubber ring is elastic and certain due to itself having
Pliability, be bonded closely with the surface of screw-thread steel, improve frictional force, when enhancing two screw-thread steels and being arranged in hollow shaft
Bonding strength.
Further, the metal layer is made of elastic sheet metal；Wherein, when the first screw set and the second screw set spiral shell
When line connection tightening hollow shaft, elastic sheet metal is under pressure, towards generating deformation on the inside of its axle center, to being arranged in hollow shaft
Two spirals apply pressure, to firmly connect two spirals, have reached easy for construction, the effect being connected firmly
Fruit.
Wherein, the inner wall of first screw set and the second screw set is provided with internal screw thread, and the outer ring of the hollow shaft is set
It is equipped with external screw thread, first screw set and the second screw set are threadedly coupled with the hollow shaft.
Beneficial effect acquired by the utility model is: the connector of this connection screw thread reinforcing bar, facilitates construction, connection jail
Gu；It can securely be connected, be had a wide range of application for the reinforcing bar of different structure, it is easy to operate, it uses manpower and material resources sparingly.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention without any creative labor, may be used also for those of ordinary skill in the art
To obtain other drawings based on these drawings.
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is the structural section structural schematic diagram of Fig. 1 hollow mandrel.
In figure, hollow shaft 1, the first screw set 2, the second screw set 3, longitudinal rib hole 4, cross rib hole 5, elastomeric layer 6, metal
Layer 7, anti-skidding pawl 8.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
Embodiment
Shown in referring to Figures 1 and 2, a kind of connector of connection screw thread reinforcing bar, including hollow shaft 1, rotation be connected to it is described
First screw set 2 and the second screw set 3 at 1 both ends of hollow shaft；The hollow shaft 1 is by elastomeric layer 6 and is wrapped in the bullet
Property 6 outer ring of material layer metal layer 7 form.
For the friction for improving hollow shaft 1 inner wall and screw thread steel surface, the inner wall of the hollow shaft 1 is provided with anti-skidding pawl
8。
Further, the surface of the hollow shaft 1 is evenly equipped with cross rib hole 5 along axial direction and axially spaced longitudinal rib hole is distributed with
4, the cross rib hole 5 and the cross rib of screw-thread steel match, and the longitudinal rib hole 4 and the longitudinal rib of screw-thread steel match；It should be understood that cross rib
The cross rib and longitudinal rib on spiral surface are entangled in hole 5 and longitudinal rib hole 4, improve the fastness that hollow shaft 1 is connect with spiral.
In the present embodiment, the elastomeric layer 6 is made of rubber ring；The metal layer 7 is made of elastic sheet metal.
Wherein, the inner wall of first screw set 2 and the second screw set 3 is provided with internal screw thread, the outer ring of the hollow shaft 1
