AI Technical Summary
The existing threaded sleeves are troublesome to operate when installing steel bars, requiring multiple workers to cooperate, and are inefficient.
A steel bar sleeve is designed, and its cylinder body consists of a left arc plate and a right arc plate with threads provided on the inner wall. A sleeve that cooperates with the steel bar threads is formed by extrusion through equipment. The threads of the inner wall of the cylinder do not restrict the end of the steel bar threads during installation, allowing two steel bars to be inserted directly. After installation, the inner wall thread and the steel bar thread are formed to be intercepted by extrusion.
The two steel bars are quickly and conveniently connected, reducing operating steps and manpower requirements, and improving installation efficiency.

[0002] The rebar sleeve, also known as the rebar joint, is used to connect rebars. The current rebar sleeves are divided into cold-extruded sleeves and threaded sleeves. The threaded sleeves are connected to the rebar thread for fixation. When in use, the end of the rebar is processed into a straight thread by a rolling process, and the corresponding threaded sleeves are used to connect the two rebars to each other for fixation.
[0003] At present, when a threaded sleeve is used to install and fix two steel bars, the operation steps are as follows: first, the threaded sleeve needs to be screwed into the threaded end of one of the steel bars, and then another steel bar is prepared, its threaded end is aligned with the threaded sleeve, and then the steel bar is rotated to make the threaded end of the steel bar screwed into the threaded sleeve to achieve the connection of the two steel bars; however, due to the long length of the steel bar, it is more troublesome for workers to drive the steel bar to rotate, and in the docking installation process, not only must the threaded sleeve be prevented from rotating, but the two steel bars must also be in the same straight line to ensure that the threaded end of the steel bar is aligned with the threaded sleeve before the threaded end can be screwed in. This usually requires more than three workers to cooperate to complete the operation, which makes the installation efficiency low and the operation more troublesome. Utility Model Content

[0018] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the utility model.
[0019] like Figure 1-4 As shown, the present embodiment discloses a steel bar sleeve, comprising a cylinder 1, wherein the cylinder 1 comprises a left arc-shaped plate 11 and a right arc-shaped plate 12 with threads on the inner walls, wherein one side of the left arc-shaped plate 11 and the right arc-shaped plate 12 are fixedly connected and integrally formed, and the other side is connected by a connecting structure 2; and an opening is formed between the one side plates connected by the connecting structure 2, so that one side of the cylinder 1 is in an open state, and thus the threads on the inner wall of the cylinder 1 cannot restrict the threaded ends of the steel bars, so that the two steel bars can be directly inserted into the cylinder 1 when connected, and the positions of the two steel bars in the cylinder 1 can be adjusted conveniently; at the same time, when installing the steel bars, workers do not need to rotate the steel bars, which is more suitable for the connection between two longer steel bars.
[0020] Then, after completing the position adjustment between the two steel bars and the cylinder 1, a worker can hold the ends of the two steel bars to ensure the stability of the position between the steel bars and the sleeve, and then another worker can operate the extrusion equipment to extrude the left and right arc plates, so that one side of the left and right arc plates that are integrally formed becomes bent, so that the cylinder 1 changes from an open state to a closed state, forming a sleeve that cooperates with the steel bar thread, so that the thread in the cylinder 1 engages with the steel bar thread end, and realizes the threaded connection between the cylinder 1 and the steel bar; the sleeve formed by the above is more convenient during installation, and after the installation is completed, the staff can also complete the disassembly and separation of the two steel bars by rotating the sleeve.
[0021] The inner wall of the cylinder 1 is provided with a V-shaped deformation groove 3 along its length direction, and the deformation groove 3 is located at the connection where the left arc plate 11 and the right arc plate 12 are fixedly connected. When the staff extrude the cylinder 1 through the extrusion equipment, the left arc plate 11 and the right arc plate 12 can bend and deform along the V-shaped deformation groove 3, so that the other sides of the left and right arc plates are close to each other until the opening is closed; the setting of the deformation groove 3 allows the cylinder 1 to control the bending position when it is deformed and bent, so that the shape of the cylinder 1 after forming is more controllable, ensuring that the other sides of the left and right side plates correspond to each other during the bending process, avoiding the connection structure 2 on the other side from being unable to be connected.
[0022] like Figure 1-2As shown, the connecting structure 2 includes a clamping member 21 arranged on one side of the left arc-shaped plate 11 and a clamping groove 22 arranged on one side of the right arc-shaped plate 12. The clamping member 21 includes a connecting plate 23 arranged on one side of the left arc-shaped plate 11 and extending toward the right arc-shaped plate 12. The connecting plate 23 is inclined to be away from the side of the left arc-shaped plate 11 and is provided with an elastically deformable limiting head 24. A bending portion 25 is provided between the limiting head 24 and the connecting plate 23. When the left and right side plates are squeezed, the clamping member 21 on the left side plate and the clamping groove 22 on the right side plate will approach each other. During the approaching process, the limiting head 24 will first abut against the opening of the clamping groove 22 to form a shape. The U-shaped bent portion 25 can provide elastic deformation between the limit head 24 and the connecting plate 23, so that the limit head 24 can be deformed and reset under the action of elastic force after being inserted into the connecting groove 22, so that one side of the left arc plate 11 and the right arc plate 12 can be mutually locked and locked with the connecting piece 21 and the connecting groove 22, thereby improving the connection strength between the left arc plate 11 and the right arc plate 12, and avoiding the deformation of the left and right arc plates after being subjected to force, which causes the steel bar and the cylinder 1 to loosen.
[0023] And as Figure 3-4 As shown, a locking member 4 is further provided between the connecting plate 23 and the limiting head 24, and the locking member 4 is inserted into the gap formed between the connecting plate 23 and the limiting groove. By filling the gap with the locking member 4, the limiting head 24 can be prevented from being deformed by external force, thereby limiting and locking the connection between the clamping member 21 and the clamping groove 22, thereby further strengthening the connection strength between the left and right arc-shaped plates.
[0024] A threaded hole 5 is provided at the gap between the connecting plate 23 and the limiting head 24. The locking member 4 may be a bolt, which can be screwed into the threaded hole 5 to lock the position of the limiting head 24. The bolt and the threaded hole 5 make the operation of the staff more convenient and quick. A conical guide surface 6 is provided at one end inserted into the threaded hole 5. If the gap between the limiting head 24 and the connecting plate 23 is deformed during the process of inserting the clamping member 21 into the clamping groove 22, the limiting head 24 can be squeezed by the guide surface 6 during the process of inserting the threaded hole 5, so that the locking member 4 can be smoothly inserted into the bolt.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
