Description

Technical Field

[0001] This utility model relates to the field of railway freight car technology, and in particular to a freight car locking mechanism that prevents the locking rod from slipping out. Background Technology

[0002] The door latch used to lock the lower side door of a freight open wagon operates on the principle of gravity locking. When the door latch and the lower side door hinge wear out and the gap becomes too large, the locking rod will rotate and open under vehicle vibration, causing the door latch to fail to lock. At the same time, since open wagons need to be unloaded by tippers during use, the vehicle will tilt, and the locking rod will also rotate and fail during the tilting process, causing the lower side door to open unexpectedly. Therefore, preventing the locking rod from popping out is particularly important.

[0003] Currently, existing truck locking mechanisms cannot limit and fix the locking rod during use. Most existing ones use wire to bind the lower door locking rod, which is not only time-consuming and labor-intensive, but also has poor stability. Therefore, in order to improve the stability of truck locking mechanisms and to promote technological progress in the industry and enhance core technological competitiveness, this application proposes a new implementation scheme that is different from the existing truck locking mechanisms and application methods. Summary of the Invention

[0004] The purpose of this utility model is to solve the problem that existing truck locking mechanisms cannot limit and fix the locking rod, and to propose a truck locking mechanism that prevents the locking rod from slipping out.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A truck locking mechanism to prevent the locking rod from slipping out includes a truck body and a side door. Two rotating seats are fixedly connected to one side of the truck body. A connecting plate is rotatably connected between the inner walls of the two sides of the rotating seats via a rotating shaft. The side door is fixed to the inner side of the connecting plate with bolts. Two latch seats are fixedly connected to one side of the truck body. Two support seats are fixedly connected to one side of the latch seats. The other end of the connecting plate is inserted between the two support seats. A locking rod is rotatably connected between the inner walls of the two sides of one of the support seats via a rotating shaft. A limit stop is fixedly connected to the top of the locking rod. The other support seat has a slot. The locking rod engages with the slot and contacts the connecting plate. A sliding rod is slidably inserted into the bottom inner wall of the slot. A pressure plate is fixedly connected to the top of the sliding rod. The locking rod contacts the pressure plate. A lifting spring is sleeved on the outer wall of the sliding rod. Two mounting seats are fixedly connected to one side of the connecting plate. A handle is rotatably connected between the two mounting seats. Both ends of the handle are sleeved with torsion springs. The handle presses on the locking rod and is located inside the limit stop.

[0006] Furthermore, a lever is fixedly connected to one end of the locking rod, and one end of the lever has an arc-shaped structure.

[0007] Furthermore, the top end of the lifting spring is fixedly connected to the pressure plate, and the bottom end of the lifting spring is fixedly connected to the bottom inner wall of the slot.

[0008] Furthermore, a reinforcing rib is fixedly connected to one side of the buckle seat, and one side of the reinforcing rib is fixedly connected to one side of the support seat.

[0009] Furthermore, the outer wall of the handle is fitted with a rubber sleeve.

[0010] Furthermore, the locking rod has a rectangular structure.

[0011] Furthermore, the handle has a C-shaped structure.

[0012] The beneficial effects of this utility model are as follows: 1. By pressing the handle downwards under the action of the torsion spring, and at the same time, by pressing the lifting spring, the pressure plate lifts the locking rod upwards. Thus, the locking rod and the handle are mutually restrained by the up-and-down pressing of the locking rod, so that the locking rod is firmly locked in the slot, thereby securely locking the side door.

[0013] 2. The addition of reinforcing ribs strengthens the connection between the latch seat and the support seat, thereby further improving the stability of the side door locking. Attached Figure Description

[0017] Reference Figures 1-3A truck locking mechanism to prevent the locking rod from slipping out includes a cargo box 1 and a side door 2. Two rotating seats 3 are welded to one side of the cargo box 1. A connecting plate 4 is rotatably connected between the inner walls of the two sides of the rotating seats 3 via a rotating shaft. The side door 2 is fixed to the inner side of the connecting plate 4 by bolts. Two latch seats 5 are fixed to one side of the cargo box 1 by bolts. Two support seats 6 are welded to one side of the latch seats 5. The other end of the connecting plate 4 is inserted between the two support seats 6. A locking rod 8 is rotatably connected between the inner walls of the two sides of one support seat 6 via a rotating shaft. A limit stop 13 is welded to the top of the locking rod 8. A slot 7 is provided on the other support seat 6. The locking rod 8 engages with the slot 7 and contacts the connecting plate 4. Rotating the connecting plate 4 downwards causes the side door 2 to close on the cargo box 1. At the same time, one end of the connecting plate 4 is inserted between the two support seats 6. Then, the locking rod 8 is engaged in the slot 7, thereby pressing the locking rod 8 against one end of the connecting plate 4 and locking the side door 2. A sliding rod 10 is slidably inserted into the bottom inner wall of the slot 7. A pressure plate 11 is welded to the top of the sliding rod 10. The locking rod 8 contacts the pressure plate 11. A lifting spring 12 is sleeved on the outer wall of the sliding rod 10. The stiffness of the lifting spring 12 is 100-200 N / mm. Two mounting seats 14 are welded to one side of the connecting plate 4. A handle 15 is rotatably connected between the two mounting seats 14. Both ends of the handle 15 are sleeved with torsion springs 16. The torque value of the torsion springs 16 is 5-10 N·m to ensure the effect of use. The handle 15 is pressed on the locking rod 8. The handle 15 is located inside the limiting block 13. The handle 15 is moved to make it contact the locking rod 8 and the limiting block 13. Under the action of the torsion spring 16, the handle 15 presses the locking rod 8 downward. At the same time, under the action of the lifting spring 12, the sliding rod 10 and the pressure plate 11 move upward, thereby lifting the locking rod 8 upward. Then, by pressing the locking rod 8 up and down, the locking rod 8 and the handle 15 form a mutual restraint, thereby firmly locking the side door 2.

[0018] One end of the locking lever 8 is integrally formed with a lever 9, and one end of the lever 9 has an arc-shaped structure, which facilitates the operation of the locking lever 8; The top end of the lifting spring 12 is fixedly connected to the pressure plate 11, and the bottom end of the lifting spring 12 is fixedly connected to the bottom inner wall of the slot 7. A reinforcing rib plate 17 is welded to one side of the hook and loop seat 5. One side of the reinforcing rib plate 17 is fixedly connected to one side of the support seat 6, thereby strengthening the connection between the hook and loop seat 5 and the support seat 6. A rubber sleeve 18 is fitted onto the outer wall of the handle 15 to facilitate the operation of the handle 15; The locking bar 8 has a rectangular structure, and the handle 15 has a C-shaped structure.

[0019] The working principle of this embodiment is as follows: When in use, the connecting plate 4 is rotated downward to close the side door 2 on the panel 1. At the same time, one end of the connecting plate 4 is inserted between the two support seats 6. Then, the locking rod 8 is locked in the slot 7, so that the locking rod 8 is pressed against one end of the connecting plate 4. Then, the handle 15 is turned to make it contact the locking rod 8 and the limiting block 13. Under the action of the torsion spring 16, the handle 15 is pressed downward to squeeze the locking rod 8. At the same time, under the action of the lifting spring 12, the sliding rod 10 and the pressure plate 11 are moved upward to lift the locking rod 8 upward. Then, by pressing the locking rod 8 up and down, the locking rod 8 and the handle 15 are mutually restrained, so that the locking rod 8 is firmly locked in the slot 7, thereby keeping the side door 2 locked. When it is necessary to open the side door 2, press down on the lever 9 to make the locking rod 8 rotate downward, thereby separating the locking rod 8 from the handle 15. Then, pull the handle 15 outward, and then pull up the lever 9 to make the locking rod 8 separate from the slot 7. Next, pull the connecting plate 4 outward to open the side door 2.
