[0002] A rebar sleeve, also known as a rebar connector, is a connecting component used to connect rebars and has an internal thread corresponding to the threaded rebar. The simple construction process involves rolling the ends of the rebars into straight threads and then connecting the two rebars together using a suitable connecting sleeve. In railway construction, whether it's for connecting threaded rebars in pile foundation cages, pier caps, or continuous beams, a large number of sleeves are required.

[0028] Example 1

[0029] See Figures 1 to 5 This utility model provides a rebar sleeve installation tool, including an electric drill 1, a detachable connecting sleeve 2 on the electric drill 1, a clamping sleeve 3 slidably disposed inside the connecting sleeve 2, an operating rod 4 rotatably disposed at one end of the connecting sleeve 2 near the electric drill 1, and a release rod 5 rotatably disposed on the connecting sleeve 2 located on one side of the operating rod 4.

[0030] An angle 6 is provided at the end of the connecting sleeve 2 away from the electric drill 1, and the angle 6 is located at one end of the inner wall of the connecting sleeve 2;

[0031] A beveled boss 7 is provided at the end of the clamping sleeve 3 away from the internal thread. The beveled boss 7 corresponds to the bevel angle 6 of the connecting sleeve 2. The end of the beveled boss 7 away from the internal thread is away from the axis of the clamping sleeve 3.

[0032] Several gap grooves 8 are provided at the end of the clamping sleeve 3 away from the internal thread, and the gap grooves 8 are evenly distributed in a circumferential manner.

[0033] The connecting sleeve 2 is detachably installed onto the drill chuck of the electric drill 1 to complete the connection between the installation tool and the power source. Then, the steel bar to be connected is inserted into the clamping sleeve 3 so that the steel bar is located in the space enclosed by several gap grooves 8.

[0034] Next, rotate the operating lever 4. The operating lever 4 drives the clamping sleeve 3 to move towards the side of the electric drill 1. During the movement, the inclined boss 7 of the clamping sleeve 3 gradually contacts the inclined angle 6 of the inner wall of the connecting sleeve 2. Due to the guiding effect of the inclined surface, the side wall of the gap groove 8 contracts inward, thereby clamping the steel bar tightly.

[0035] When it is necessary to disassemble the rebar sleeve, rotate the operating lever 4 in the opposite direction, and then rotate the release lever 5. The release lever 5 pushes the clamping sleeve 3 to slide in the opposite direction, so that the inclined boss 7 is separated from the inclined angle 6 of the connecting sleeve 2, the gap groove 8 loses the squeezing constraint and opens, and the rebar can be taken out smoothly.

[0036] By combining the electric drill 1 as the power source with the manual control of the operating lever 4 and the release lever 5, the system achieves a combination of power drive and precise manual adjustment. Compared with traditional purely manual installation tools, this significantly improves the efficiency of installing and disassembling rebar sleeves and reduces the labor intensity of workers.

[0037] The end of the clamping sleeve 3 away from the through groove 10 is provided with an internal thread, and the drive sleeve 9 is connected to the internal thread.

[0038] The drive cylinder 9 is cylindrical, and one end of the drive cylinder 9 is provided with an external thread. The external thread of the drive cylinder 9 is threadedly connected to the internal thread of the clamping sleeve 3.

[0039] A through groove 10 is provided in the middle of the clamping sleeve 3, and an elongated groove 11 is provided in the middle of the side wall of the through groove 10.

[0040] The operating lever 4 includes a cam 12 that is rotatably connected to the connecting sleeve 2. The cam 12 is located in the through groove 10 and the rotation axis of the cam 12 slides in the elongated groove 11.

[0041] A handle 13 is fixedly installed on the side wall of the cam 12, and the handle 13 extends to the outside of the connecting sleeve 2;

[0042] The release rod 5 is L-shaped, with the shorter end of the release rod 5 located inside the connecting sleeve 2 and the longer end located outside the connecting sleeve 2.

[0043] When installing reinforcing bars, grasp the handle 13 of the operating lever 4 and rotate it. The handle 13 drives the cam 12 to rotate within the through groove 10 of the connecting sleeve 2. Since the rotation axis of the cam 12 slides within the elongated groove 11, the rotation of the cam 12 pushes the clamping sleeve 3 towards the electric drill 1, thereby clamping the reinforcing bar. When it is necessary to remove the reinforcing bar, rotate the handle 13 in the opposite direction to slightly loosen the clamping sleeve 3, and then rotate the release lever 5. The shorter end of the release lever 5 pushes the clamping sleeve 3 to slide in the opposite direction within the connecting sleeve 2, causing the inclined boss 7 of the clamping sleeve 3 to disengage from the inclined angle 6 of the connecting sleeve 2, thus completing the removal of the reinforcing bar.

[0044] A ball head is fixedly installed at one end of the release lever 5 and the operating lever 4 located on the outside of the connecting sleeve 2.

[0045] A sealing plate 14 is fixedly installed at one end of the connecting sleeve 2, and an insertion rod 15 is fixedly installed in the middle of the sealing plate 14. The insertion rod 15 is detachably connected to the drill chuck of the electric drill 1.

[0046] The construction workers first connect the connecting sleeve 2 to the drill chuck of the electric drill 1 through the insert rod 15 in the middle of the sealing plate 14. During operation, the drill chuck of the electric drill 1 is opened, the insert rod 15 is inserted into the center hole of the drill chuck, and then the drill chuck is tightened to firmly fix the insert rod 15 in the drill chuck, thereby completing the detachable connection between the connecting sleeve 2 and the electric drill 1, providing a power foundation for the subsequent installation of steel bars.

[0047] When it is necessary to replace the connecting sleeve 2 with a different specification, simply open the drill chuck again and pull the insert rod 15 out of the drill chuck to quickly disassemble the connecting sleeve 2. The operation is simple and convenient.

[0048] When using this utility model, the connecting sleeve 2 is installed into the drill chuck of the electric drill 1 through the insertion rod 15, and the steel bar is inserted into the clamping sleeve 3; the operating rod 4 is rotated to push the clamping sleeve 3 to slide, and the inclined boss 7 cooperates with the inclined angle 6 of the connecting sleeve 2 to tighten the gap groove 8 and clamp the steel bar.

[0049] During disassembly, rotate the operating lever 4 in the opposite direction, then rotate the release lever 5 to push the clamping sleeve 3 to slide in the opposite direction, the inclined surface disengages, the gap groove 8 resets, and the reinforcing bar can be removed.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
