Detailed Implementation

[0013] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example 1 like Figures 1 to 2As shown, a stainless steel ball core cut-off gate anti-misrotation device includes a card seat 1, a stop plate 2 and a bolt 3. The card seat 1 is attached to the handle at the top of the stainless steel ball core cut-off gate. The stop plate 2 is located on the rear side of the card seat 1 and is installed on the card seat by the bolt 3. The front side of the stop plate 2 abuts against the stainless steel ball core cut-off gate.

[0015] The card holder 1 is attached to the handle at the top of the stainless steel ball core cut-off gate. The stop plate 2 abuts against the stainless steel ball core cut-off gate from the rear side of the card holder 1. The card holder 1 and the stop plate 2 are then fixed by bolts 3. The stainless steel ball core cut-off gate is in planar contact with the stop plate 2. The handle of the stainless steel ball core cut-off gate is limited by the card holder 1 and the stop plate 2 to prevent the stainless steel ball core cut-off gate from turning accidentally. An anti-loosening shim 4 is set between the card holder 1 and the stop plate 2. During normal railway transportation, vibrations occur, and the anti-loosening shim 4 can provide better cushioning.

[0016] The rear end of the card holder 1 is provided with a groove 5, and a circular through groove 6 adapted to the stainless steel core cut-off plug door handle is provided in the groove 5. The top of the card holder 1 is provided with a straight groove 7 adapted to the handle, and the straight groove 7 is connected to the circular through groove 6.

[0017] The groove 5 at the rear end of the card holder 1 can be aligned with the stainless steel ball core cut-off gate. The card holder 1 can be snapped into place from below the handle of the stainless steel ball core cut-off gate. The handle is located in the straight groove 7 at the top of the card holder 1. The circular through groove 6 of the card holder 1 fits the round rod of the handle. The card holder 1 fits the stainless steel ball core cut-off gate more closely, and the anti-misoperation effect is better. The overall structure is simple, easy to install, and convenient to use.

[0018] Example 2 like Figures 3 to 5 As shown, it also includes a mounting cap 8, a threaded rod 9, and an L-shaped plate 10. The mounting cap 8 is set on the top of the stainless steel ball core cut-off plug door handle. The rotation of the threaded rod 9 is mounted on the top of the mounting cap 8. The straight section of the L-shaped plate 10 is threadedly connected to the threaded rod 9. The vertical section of the L-shaped plate 10 extends to the rear side of the stop plate 2. The contact surface between the L-shaped plate 10 and the stop plate 2 is an inclined surface.

[0019] The mounting cap 8 is installed on the top of the stainless steel ball core cut-off plug handle. The card seat 1 is located below the mounting cap 8. The handle of the stainless steel ball core cut-off plug is sleeved in the straight groove 7 on the card seat 1. Rotating the threaded rod 9 can drive the L-shaped plate 10 to move in the height direction. After the card seat 1 and the stop plate 2 are installed, the stop plate 2 is installed on the card seat 1 by the bolt 3. There is a distance between the stop plate 2 and the bolt 3 for the stop plate 2 to slide back and forth. The vertical section of the L-shaped plate 10 is located behind the stop plate 2. When the threaded rod 9 is rotated to drive the L-shaped plate 10 to move downward, the contact surface between the vertical section of the L-shaped plate 10 and the stop plate 2 is inclined. The L-shaped plate 10 and the stop plate 2 are pressed together by the inclined surface, which presses the stop plate 2 against the card seat 1 to prevent the stainless steel ball core cut-off plug from turning accidentally.

[0020] It also includes a U-shaped rod 11, which is fixedly connected to the L-shaped plate 10. The U-shaped rod 11 is located on the front side of the L-shaped plate 10. The top of the card holder 1 has two sliding grooves 12 that are symmetrically arranged on the left and right. The vertical sections on both sides of the U-shaped rod 11 extend downward into the two sliding grooves 12 on the top of the card holder 1. The U-shaped rod 11 and the card holder 1 slide together in the height direction.

[0021] When the rotating threaded rod 9 drives the L-shaped plate 10 to move, the U-shaped rod 11 has a limiting effect on the L-shaped plate 10, preventing the L-shaped plate 10 from rotating, and the L-shaped plate 10 can move up and down more stably.

[0022] A limiting block 13 is provided at the bottom of the vertical section of the U-shaped rod 11, and a limiting groove 14 is opened on the side of the slide 12 facing the limiting block 13. The limiting block 13 is slidably disposed in the limiting groove 14 in the height direction.

[0023] During daily railway transportation operations, the cap 8 is installed on the top of the stainless steel ball core cut-off plug handle. The stainless steel ball core cut-off plug handle is sleeved in the straight groove 7 of the card seat 1. Rotating the threaded rod 9 drives the L-shaped plate 10 to move downward, pressing the stop plate 2 and the card seat 1 together. The stop plate 2 contacts the stainless steel ball core cut-off plug plane, fixing the handle of the stainless steel ball core cut-off plug and preventing the stainless steel ball core cut-off plug from turning accidentally.

[0024] When the stainless steel ball core cut-off gate needs to be rotated, the threaded rod 9 is rotated in the opposite direction to drive the L-shaped plate 10 to move upward. The U-shaped rod 11 moves upward with the L-shaped plate 10, and the limiting block 13 moves upward in the limiting groove 14 and contacts the inner top surface of the limiting groove 14. At this time, the vertical section of the L-shaped plate 10 separates from the stop plate 2, and the stop plate 2 and the card seat 1 are in a relaxed state. The threaded rod 9 is rotated to drive the L-shaped plate 10 to rise, and the limiting block 13 continues to rise, driving the card seat 1 to rise. The stop plate 2 rises with the card seat 1 and separates from the stainless steel ball core cut-off gate. At this time, the stainless steel ball core cut-off gate is in a rotatable open state. The handle of the stainless steel ball core cut-off gate is still sleeved in the card seat 1. It is not necessary to remove the entire device to rotate the stainless steel ball core cut-off gate, which makes it easier for the staff to operate.

[0025] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
