[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the embodiments, by Figure 1 A clamping device for bathroom steel pipe production is provided, comprising a mounting plate 1, a clamping arm 2 fixedly connected to the left end of the mounting plate 1, L-shaped protrusions 3 fixedly connected to both the front and rear ends of the clamping arm 2, the outer sides of the two L-shaped protrusions 3 being slidably connected to a sliding mechanism 4, a pressing mechanism 5 provided at the top of the sliding mechanism 4, a bend 6 provided at the bottom end of the clamping arm 2, a bottom clamping wheel 7 detachably connected to the inner side of the bend 6 by screws, and a top clamping wheel 8 detachably connected to the inner side of the sliding mechanism 4 by screws.

[0020] With the above setup, the bathroom steel pipe to be processed is first placed horizontally on two bottom clamping wheels 7. The bottom clamping wheels 7 form a stable supporting surface through the support of the bend 6. The pressing mechanism 5 at the top of the sliding mechanism 4 is operated, driving the sliding mechanism 4 to slide vertically downward along the L-shaped protrusions 3 at both ends of the clamping arm 2. The inner top clamping wheel 8 of the sliding mechanism 4 moves down accordingly, forming an upper and lower alignment with the bottom clamping wheel 7. The steel pipe is clamped by the synchronous contact of the two wheels. The clamping wheels fixed by screws can adapt to different pipe diameters, ensuring a uniform distribution of clamping force. After processing, the pressing mechanism 5 is operated in reverse, and the top clamping wheel 8 moves up to release the steel pipe, completing the clamping process. The sliding cooperation between the L-shaped protrusion 3 and the sliding mechanism 4 provides precise vertical guidance, avoiding lateral deviation and ensuring... The steel pipe clamping stability is enhanced, and the lateral protrusion of the L-shaped protrusion 3 can act as a limit to prevent the sliding mechanism 4 from disengaging from the L-shaped protrusion 3. The pressing mechanism 5 can finely adjust the height of the top clamping wheel 8 to adapt to steel pipes of different diameters without replacing the overall structure, thus improving versatility. Both the bottom clamping wheel 7 and the top clamping wheel 8 adopt a screw-removable design, which can be directly replaced after wear, reducing downtime and maintenance costs. The rigid connection between the bend 6 and the mounting plate 1 enhances the structural strength, avoids device deformation caused by pressure during clamping, and extends service life. It should be noted that the bottom clamping wheel 7 and the top clamping wheel 8 can be made of rubber to avoid forming notches on the outer surface of the steel pipe during clamping. Notches can also be provided on the outer side of the bottom clamping wheel 7 and the top clamping wheel 8 to adapt to the steel pipe.

[0021] Reference Figure 1 The sliding mechanism 4 includes an L-shaped slide plate 41. The front end of the front L-shaped protrusion 3 and the rear end of the rear L-shaped protrusion 3 are slidably connected to the L-shaped slide plate 41. A slider 42 is provided between the two L-shaped slide plates 41. The two L-shaped slide plates 41 and the slider 42 are detachably connected by bolts. The top clamping wheel 8 is detachably connected to the inner side of the slider 42 by screws.

[0022] Through the above structural design, the L-shaped sliding plate 41 and the L-shaped protrusions 3 on the front and rear sides of the clamping arm 2 slide together on both sides to form a bidirectional limiting guide, which prevents the sliding mechanism 4 from horizontally shifting or shaking when moving vertically, ensuring that the top clamping wheel 8 and the bottom clamping wheel 7 are accurately aligned, thus improving clamping accuracy. The slider 42 is detachably connected to the L-shaped sliding plates 41 on both sides by bolts, which supports the quick disassembly or reassembly of the entire sliding mechanism 4, facilitating local maintenance without disassembling the entire device, significantly reducing maintenance time. As a connecting part, the slider 42 evenly distributes the driving force of the pressing mechanism 5 to the L-shaped sliding plates 41 on both sides, avoiding local deformation caused by unilateral force, while enhancing the overall rigidity of the sliding mechanism 4 and extending its service life. The top clamping wheel 8 is fixed to the inside of the slider 42 by screws, which supports the quick replacement of different specifications of top clamping wheels 8 according to the diameter of the steel pipe (such as adjusting the groove depth / width), adapting to the processing needs of multiple specifications of steel pipes and improving the versatility of the equipment.

[0023] Reference Figure 1 The pressing mechanism 5 includes a screw 51, the inner side of the slider 42 is rotatably limited by the screw 51, the screw 51 is threadedly connected to the inner side of the clamping arm 2, and the top end of the screw 51 is fixedly connected to a crank 52.

[0024] With the above structural design, the threaded connection between the screw 51 and the clamping arm 2 has self-locking properties, which can automatically lock the position after the operation stops, preventing the top clamping wheel 8 from accidentally moving upward due to vibration or external force during the processing, ensuring a stable and reliable clamping state. The crank handle 52 extends the lever arm, reducing the manual operating force required to rotate the screw 51 and reducing the labor intensity of workers. At the same time, the rotation limit design of the screw 51 and the slider 42 reduces non-axial friction and extends the service life of the threaded pair.

[0025] Reference Figure 1 The mounting plate 1 has mounting holes 9.

[0026] With the above structural design, the opening of mounting hole 9 allows the mounting plate 1 to be fixed to workbenches, brackets or assembly line bases of different specifications by bolts or pins, adapting to the needs of multiple scenarios such as workshops and mobile processing equipment, and improving the deployment flexibility of the device.

[0027] Reference Figure 1 Two triangular plates 10 are fixedly connected to the left end of the mounting plate 1, and the two triangular plates 10 are fixedly connected to the front and rear ends of the clamping arm 2 respectively.

[0028] With the above structural design, the triangular plate 10 connects the front and rear ends of the mounting plate 1 and the clamping arm 2 in a stable triangular configuration, which significantly improves the bending and torsional resistance of the connection area, avoids deformation of the joint between the mounting plate 1 and the clamping arm 2 due to lateral force when clamping the steel pipe, ensures the rigidity of the overall device, and during the clamping process, the downward pressure borne by the clamping arm 2 is evenly transmitted to the mounting plate 1 through the inclined structure of the triangular plate 10, avoiding stress concentration at a single welding point or bolt connection, reducing the risk of metal fatigue fracture after long-term use, and extending the life of the device.
