However, the push plate design of the traditional hoop bending machine has poor mobility in the horizontal direction, making it difficult to meet the hoop bending needs of steel bars of different sizes. In addition, due to the limitations of the traditional push plate design, the hoop bending machine often needs to replace or adjust the entire push plate mechanism when dealing with steel bars of different specifications, which not only increases the manufacturing cost and maintenance difficulty of the equipment, but also limits the flexibility and applicability of the hoop bending machine. Therefore, a telescopic mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0025] Example 1: A telescopic mechanism includes a first fixed seat 1, a load-bearing seat 2, a second fixed seat 8, a push column and a telescopic assembly, wherein the load-bearing seat 2 is located on top of the first fixed seat 1 and the telescopic assembly is provided between the two;

[0026] The telescopic assembly includes a fixed block 3 and a rotating rod 5. The rotating rod 5 is arranged in the internal groove of the first fixed seat 1 and both ends of the rotating rod 5 are rotatably connected to the inner wall of the first fixed seat 1 through bearings. The fixed block 3 consists of a connecting plate 301 and two insertion rods 302. The insertion rods 302 are plugged into the load-bearing seat 2 and the first fixed seat 1.

[0027] In this embodiment, a protrusion is provided at the bottom of the load-bearing seat 2 and is slidingly connected to the internal groove of the first fixed seat through the protrusion. A thread is provided on the outside of the rotating rod 5 and is threadedly connected to the protrusion of the load-bearing seat 2. One end of the rotating rod 5 passes through the first fixed seat 1 and is bolted to the output end of the motor 7.

[0028] It should be noted that the threaded connection between the outer thread of the rotating rod 5 and the threaded connection between the protrusions at the bottom of the bearing seat 2 ensures precise horizontal adjustment of the bearing seat 2. When the motor 7 drives the rotating rod 5 to rotate, the interaction of the threads causes the bearing seat 2 to move along the axis of the rotating rod 5, thereby achieving the telescopic function.

[0029] In this embodiment, two guide columns 6 are inserted into the protrusion of the load-bearing seat 2. Both ends of the guide columns 6 are fixed to the inner wall of the internal groove of the first fixing seat 1 by bolts. Two groups of arranged fixing holes are also opened on the top of the first fixing seat 1.

[0030] It should be noted that the provision of two guide posts 6 not only enhances the stability of the telescopic mechanism but also provides guidance for the load-bearing base 2 during movement. Both ends of the guide posts 6 are bolted to the inner wall of the groove within the first fixed base 1, ensuring that the load-bearing base 2 does not deviate from the predetermined trajectory during movement, ensuring accurate adjustment.

[0031] In this embodiment, a plug-in hole is provided on the top of the load-bearing seat 2, and the insertion rod 302 is plugged into the plug-in hole and the fixing hole in sequence. A screw 4 is bolted between the middle part of the fixing block 3 and the load-bearing seat 2, and hand-held plates 303 are also provided on both sides of the connecting plate 301.

[0032] It should be noted that the insertion rod 302 of the fixing block 3 is sequentially inserted into the insertion hole of the load-bearing seat 2 and the fixing hole of the first fixing seat 1. This design allows the load-bearing seat 2 to be initially fixed after being adjusted to the appropriate position. The fixing block 3 is then bolted to the middle of the load-bearing seat 2 using screws 4, ensuring the stability of the position of the load-bearing seat 2 and preventing it from moving during the hoop bending process.

[0033] In this embodiment, the second fixed seat 8 is arranged on one side of the first fixed seat 1, and a push plate 9 is slidably connected inside the second fixed seat 8. The end of the push plate 9 is fixed to the push column bolt, and a screw 10 is bolted between the push plate 9 and the second fixed seat 8. The fixed end of the telescopic column 11 is bolted to the inside of the load-bearing seat 2, and the telescopic end of the telescopic column 11 is bolted to a baffle 12.

[0034] It should be noted that a sliding groove is provided inside the second fixing seat 8 and is slidably connected to the bottom of the push plate 9 through the sliding groove.

[0035] Embodiment 2: A hoop bending machine, which is used to assist a telescopic mechanism in bending hoops, further comprising a box body 13, a thickened table 14 and a working disk 15, wherein the thickened table 14 is located on the top of the box body 13, and the working disk 15 is located on the top of the thickened table 14;

[0036] The first fixing seat 1 and the second fixing seat 8 are both bolted to the top of the thickened table 14 . A column is provided in the middle of the working disk 15 , and the line between the center of the column and the center of the push column is parallel to the side of the thickened table 14 .

[0037] It should be noted that the thickened table 14 provides a stable operating platform for the hoop bending operation, on which the working disk 15 is located. The line between the center of the column set in the middle and the center of the push column is parallel to the side of the thickened table 14. This design ensures stability and accuracy during the hoop bending process.

[0038] In this embodiment, a power switch 16 , a control panel 17 and a side door 18 are sequentially provided on the front side of the box body 13 from top to bottom and from left to right. A roller 19 is also provided at the bottom of the box body 13 .

[0039] It should be noted that the control panel 17 and power switch 16 allow the operator to conveniently control the operating status of the stirrup bender. Through the control panel 17, the operator can precisely adjust parameters such as the position of the load-bearing base 2 and the extension and contraction of the telescopic column 11 to meet the bending requirements of different steel bars. The power switch 16 is used to control the start and stop of the stirrup bender.

[0040] Working principle:

[0041] After putting in the steel bars to be bent, adjust the push plate 9 to the appropriate position, and then bolt the adjusting push plate 9 to the second fixing seat 8 by the screw 10, turn on the power switch 16 and operate the control panel 17 to adjust the load-bearing seat 2 in the horizontal direction to meet the size requirements of the steel bars to be bent. During adjustment, the motor 7 drives the rotary rod 5 to rotate. Since the rotary rod 5 is threadedly connected to the bottom protrusion of the load-bearing seat 2 and the load-bearing seat 2 drives the telescopic column 11 to move in the horizontal direction under the guiding action of the guide column, after moving to the appropriate position, the insertion rod 302 of the fixing block 3 is sequentially inserted into the plug-in through hole of the load-bearing seat 2 and the fixing hole of the first fixing seat for preliminary fixation, and then the fixing block 3 and the load-bearing seat 2 are fixed by the screw 4, and then the control panel 17 is operated to make the telescopic column 11 drive the push plate 9 to perform the bending work.

[0042] Beneficial effects:

[0043] The telescopic mechanism is connected by sliding connection between the bottom protrusion of the load-bearing seat 2 and the internal groove of the first fixed seat 1. The rotating rod 5 is threadedly connected to the protrusion of the load-bearing seat 2 and is driven to rotate by the motor 7 to achieve precise adjustment of the load-bearing seat 2 in the horizontal direction. The setting of the guide column 6 ensures the stability of the load-bearing seat 2 during the movement. In addition, the connection between the insertion rod 302 of the fixed block 3 and the load-bearing seat 2 and the first fixed seat 1 ensures the stability of the position of the load-bearing seat 2.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
