Therefore, a need exists for a steel bar straight thread coupling sleeve that solves the above problems.
Disclosure of Invention
The utility model aims to solve the technical problem that a straight threaded connection sleeve of reinforcing bar is provided, the device has solved the lower, the great problem of intensity of labour of prior art's steel bar connection sleeve butt joint efficiency, has and can dock fast, has reduced intensity of labour by a wide margin, can make up the characteristics that are applicable to not unidimensional reinforcing bar butt joint in a flexible way.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a steel bar straight thread connecting sleeve comprises a first sleeve and a second sleeve, wherein the first sleeve and the second sleeve are connected through a flange; the outer surface of the second sleeve is provided with a locking device.
Preferably, the first sleeve is a hollow sleeve with openings at two ends, and an internal thread is formed on the inner wall of the first sleeve.
Preferably, a first flange is connected to one end of the first sleeve.
Preferably, the second sleeve is a hollow sleeve with two open ends, and one end of the second sleeve is connected with a second flange to be butted with the first sleeve.
Preferably, a clamping groove is formed in one end, close to the second flange, of the inner wall of the second sleeve; 1-2 thread rolls are preferably selected in the clamping groove and are in clamping fit with threads on the surface of the steel bar.
Preferably, the second sleeve outer surface is provided with an external thread for cooperation with the locking means.
Preferably, the locking device comprises a plurality of elastic steel sheets of arc structures connected to one end of the second sleeve, and the inner wall of each elastic steel sheet is connected with a plurality of circles of annular clamping strips.
Preferably, the locking device comprises a nut which is matched and connected with the external thread on the outer surface of the second sleeve; one end of the nut is connected with a sliding sleeve which is in sleeve joint with the elastic steel sheet.
The utility model provides a pair of straight threaded connection sleeve of reinforcing bar's beneficial effect as follows:
the device can finish quick butt joint by using a simple wrench or pliers, and avoids the defects that the working face is limited when the wrench grasps the reinforcing steel bar and screws, and the construction difficulty is large when the reinforcing steel bar is too long or the working face is small; during the use, through screwing up the nut with the spanner, make the screw thread of elastic steel sheet centre gripping reinforcing bar surface just can fix the reinforcing bar, it is simple convenient to be under construction, raises the efficiency to the cost of labor has been reduced.
