[0002] Railway train latches are an important component of railway freight cars, mainly used to secure and protect cargo. The cutting precision of the latch seat has a significant impact on the assembly quality and safety of the doors.

[0003] Currently, most existing fixing mechanisms utilize a motor to drive a bidirectional threaded rod to move the clamping plate and fix the workpiece. This requires power, increasing costs. Therefore, to better reduce the processing cost of car door latch seats, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from existing car door latch seat cutting and fixing mechanisms. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem of increased processing costs by proposing a fixing mechanism for cutting car door latch seats.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixing mechanism for cutting a door latch seat includes a mounting plate. The top of the mounting plate has a mounting groove, and the inner walls on both sides of the mounting groove have sliding holes. A sliding plate is slidably connected between two sliding holes. The top of the sliding plate has a fixing mechanism, and the sliding plate has a through mounting opening. The inner wall on one side of the mounting opening has a first toothed groove. The bottom inner wall of the mounting groove has a drive shaft rotatably mounted on it via an interlocking bearing. The outer wall of the drive shaft is keyed with a first gear and a second gear. The first gear meshes with the first toothed groove. The top of the mounting plate has multiple first sliding grooves, and an L-shaped sliding plate is slidably connected between two first sliding grooves. The L-shaped sliding plate has a second toothed groove on one side, which meshes with a second gear. One end of the L-shaped sliding plate is fixedly connected to a mounting rod, and both ends of the top of the mounting rod are fixedly connected to clamps.

[0006] Furthermore, a rubber pad is adhered to one side of the clamp.

[0007] Furthermore, the fixing mechanism includes a connecting plate, which is fixed to the top of the mounting plate by bolts. A fastening bolt is threaded to the top of the connecting plate, and a pressing plate is rotatably connected to the bottom end of the fastening bolt. The pressing plate presses the slide plate.

[0008] Furthermore, two protective plates are fixedly connected to the top of the mounting plate, and the two protective plates are located on both sides of the L-shaped sliding plate.

[0009] Furthermore, a support block is fixedly connected to the top of the protective plate, and the same placement plate is fixedly connected to the top of the two support blocks.

[0010] Furthermore, each end of the placement plate is provided with two second sliding grooves, and the clamping plate can slide within the second sliding grooves.

[0011] Furthermore, fixing blocks are fixedly connected to both sides of the mounting plate, and fixing bolts are threadedly connected to the top of the fixing blocks.

[0012] Furthermore, a handle is fixedly connected to one end of the skateboard, and the outer wall of the handle is provided with anti-slip grooves.

[0013] The beneficial effects of this utility model are as follows: 1. By engaging the first toothed groove with the first gear and engaging the second gear with the second toothed groove, the L-shaped slide moves within the first groove, causing multiple clamping plates to converge towards the center and thus clamping the latch seat. This method greatly reduces costs.

[0014] 2. The rubber pad increases the friction between the clamp and the hook and loop seat, thereby preventing the hook and loop seat from slipping and thus avoiding cutting errors.

[0015] 3. By tightening the fastening bolts, the extrusion plate is moved downwards, thereby extruding and fixing the slide plate, thus maintaining the clamping state of the latch seat for cutting the latch seat. Attached Figure Description

A fixing mechanism is provided on the top of the sliding plate 5. A handle 501 is fixed to one end of the sliding plate 5 by bolts. A mounting opening is provided through the sliding plate 5. A first toothed groove 6 is provided on one inner wall of the mounting opening. A drive shaft is rotatably mounted on the bottom inner wall of the mounting groove 4 via an interlocking bearing. A first gear 10 and a second gear 11 are keyed to the outer wall of the drive shaft. The first gear 10 meshes with the first toothed groove 6. The top of the mounting plate 1 has multiple first gears... The slide 12 has an L-shaped slide plate 13 slidably connected between the two first slide grooves 12. The L-shaped slide plate 13 has a second toothed groove 14 on one side, which meshes with the second gear 11. An installation rod 15 is welded to one end of the L-shaped slide plate 13. Both ends of the top of the installation rod 15 are welded with clamps 16. Pulling the handle 501 causes the slide plate 5 to move in the slide hole. Under the action of the first toothed groove 6 meshing with the first gear 10 and the second gear 11 meshing with the second toothed groove 14, the L-shaped slide plate 13 moves in the first slide groove 12, thereby causing the multiple clamps 16 to converge towards the middle and clamp the buckle seat.

[0020] A rubber pad 17 is glued to one side of the clamp 16, which increases the friction between the clamp 16 and the buckle seat, thereby preventing the buckle seat from slipping. The fixing mechanism includes a connecting plate 8, which is fixed to the top of the mounting plate 1 by bolts. The top of the connecting plate 8 is threaded with a fastening bolt 9, and the bottom end of the fastening bolt 9 is rotatably connected to a pressing plate 7. The pressing plate 7 presses the slide plate 5. Tightening the fastening bolt 9 causes the pressing plate 7 to move downward, thereby pressing the slide plate 5 and fixing the slide plate 5, thus maintaining the clamping state of the buckle seat. Two protective plates 18 are bolted to the top of the mounting plate 1. The two protective plates 18 are located on both sides of the L-shaped sliding plate 13 to prevent debris from falling into the mounting groove 4 and thus affecting the movement of the sliding plate 5. The top of the protective plate 18 is welded with a support block 19, and the tops of the two support blocks 19 are fixed with the same placement plate 20 by bolts, which facilitates the placement of the buckle seat. The two ends of the placement plate 20 are provided with two second sliding grooves 21, and the clamping plate 16 can slide in the second sliding grooves 21, thereby facilitating the movement of the clamping plate 16. Fixing blocks 2 are welded to both sides of the mounting plate 1. Fixing bolts 3 are threadedly connected to the top of the fixing blocks 2. The fixing mechanism is fixed and installed by fixing blocks 2 and fixing bolts 3. The outer wall of the handle 501 is provided with anti-slip grooves, which facilitates the operation of the handle 501.

[0021] The working principle of this embodiment is as follows: In use, firstly, the fixing mechanism is fixed and installed by fixing block 2 and fixing bolt 3. Then, the hook and loop seat is placed on the placement plate 20. Then, the handle 501 is pulled to move the slide plate 5 in the sliding hole. Under the action of the first toothed groove 6 meshing with the first gear 10 and the action of the second gear 11 meshing with the second toothed groove 14, the L-shaped slide plate 13 moves in the first sliding groove 12, thereby causing multiple clamping plates 16 to converge towards the middle, thereby clamping the hook and loop seat. Then, the fastening bolt 9 is turned to move the pressing plate 7 downward, thereby pressing the slide plate 5 and fixing the slide plate 5, thus maintaining the clamped state of the hook and loop seat.
