The utility model provides a its technical problem take following technical scheme to realize:
a steel bar lapping connector comprises a connecting rod and a pair of connecting sleeves; the connecting sleeve is of a tubular structure with one open end and the other end provided with a through hole, the inner wall of the through hole end of the connecting sleeve is of an inclined plane structure inclined towards the through hole, the two ends of the connecting rod are respectively inserted into the connecting sleeves through the through hole, the end part of the connecting rod positioned in the connecting sleeve is provided with an enlarged end head, and the shape of the enlarged end head is matched with the inclined plane structure, so that the two ends of the connecting rod cannot be separated from the connecting sleeve through the through hole;
the outer surface of the connecting rod is provided with threads, and at least two nuts are installed through the threads.
Furthermore, the inner wall of the open end of the connecting sleeve is provided with internal threads which can be connected with the reinforcing steel bars through threads.
Furthermore, the cross section of the outer wall of the connecting sleeve is of a hexagonal structure.
Further, the connecting rod can freely move along the axial direction of the connecting sleeve through the through hole.
The utility model has the advantages that:
compared with the prior art, the steel bar lapping connector of the utility model can ensure the steel bar lapping connection to be firm and ensure the strength requirement, so that the steel bar connection operation is more convenient, the working efficiency is higher, and the steel bar lapping connector can be completed without using any machinery; and if the temporary lap joint is adopted, the connector and the steel bar can be repeatedly used due to the convenient loosening.

Detailed Description
First, it should be noted that the specific structures, features, advantages, etc. of the present invention will be described in detail below by way of example, but all the descriptions are only for illustrative purpose and should not be construed as forming any limitation to the present invention. Furthermore, any single feature described or implicit in any embodiment or any single feature shown or implicit in any drawing may still be combined or subtracted between any of the features (or equivalents thereof) to obtain still further embodiments of the invention that may not be directly mentioned herein. In addition, for the sake of simplicity, the same or similar features may be indicated in only one place in the same drawing.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The present invention will be described in detail with reference to fig. 1 to 4.
Example 1
As shown in fig. 1 to 4, the reinforcing bar overlapping connector provided in this embodiment includes a connecting rod 4 and a pair of connecting sleeves 2; the connecting sleeve 2 is a tubular structure with one open end and the other end provided with a through hole 201, the inner wall of the through hole end provided with the connecting sleeve 2 forms an inclined plane structure 202 inclined towards the through hole, the two ends of the connecting rod 4 are respectively inserted into the connecting sleeves 2 through the through holes, the end part of the connecting rod 4 positioned in the connecting sleeve 2 forms an enlarged end head 401, and the shape of the enlarged end head is matched with the inclined plane structure, so that the two ends of the connecting rod 4 can not be separated from the connecting sleeves 2 through the through holes;
the outer surface of the connecting rod 4 is provided with threads, and at least two nuts are installed through the threads, in this embodiment, as shown in fig. 1, the connecting rod 4 is sleeved with a first nut 301 and a second nut 302.
The inner wall of the open end of the connecting sleeve 2 is provided with internal threads which can be connected with the steel bar 1 through threads.
The cross section of the outer wall of the connecting sleeve 2 is of a hexagonal structure.
The connecting rod 4 can freely move along the axial direction of the connecting sleeve 2 through the through hole.
Specifically, when in actual application, when connecting sleeve 2 and reinforcing bar 1 spiro union, connecting piece one end blocks through enlarging end 401 in connecting sleeve for connecting sleeve 2 and reinforcing bar 1 are fixed, and the nut is as insurance and connecting sleeve 2 locking, prevents that connecting sleeve 2 from being not hard up because of unexpected touching and the spiral shell of reinforcing bar 1 closes, because nut structure size is less, and unexpected touching and not hard up probability is very little, can guarantee connecting sleeve 2's fastening.
By way of example, in this embodiment, when installation is performed: moving the steel bar 1 to enable the steel bar 1 to abut against the open end of the connecting sleeve 2, and then rotating the connecting sleeve 2 to be screwed and locked with the steel bar 1, wherein the process can be assisted by a handheld screwing tool; the nuts 301, 302 are locked to the connecting sleeve 2.
The above embodiments are described in detail, but the above description is only for the preferred embodiments of the present invention, and should not be construed as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
