[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a novel transmission line protection device for broadcasting and television, including a protection block 2, the protection block 2 is set to provide protection for the transmission line, the inner wall of the protection block 2 is fixedly connected with a wire harness channel 7, the setting of the wire harness channel 7 can make the transmission line pass more smoothly, and provide support for the transmission line, the rear end outer wall of the wire harness channel 7 is fixedly connected with a hinge 8, the hinge 8 is used to connect the wire harness channel 7 and the arc plate 9, the inner wall of the protection block 2 is elastically connected with the arc plate 9 through a spring 10, the spring 10 is supported by the arc plate 9, when there is no transmission line on the inner wall of the arc plate 9, the spring 10 is fixedly connected with the inner wall of the arc plate 9, the spring 10 is fixedly connected with the inner wall of the arc plate 9, and the spring 10 is fixedly connected with the inner wall of the arc plate 9. Under the action of elastic force, the right side of the arc plate 9 shrinks toward the center. When there is a transmission line on the inner wall of the arc plate 9, the transmission line pushes the right side of the arc plate 9 outward, and the spring 10 squeezes the arc plate 9 so that the arc plate 9 clamps the transmission line. The arc plate 9 is arranged in a circle with four pieces. The left outer wall of the arc plate 9 is fixedly connected to the right outer wall of the hinge 8. The left arc length of the arc plate 9 is greater than the right arc length. One end of the spring 10 is fixedly connected to the inner wall of the protective block 2, and the other end of the spring 10 is fixedly connected to the outer wall of the arc plate 9. The spring 10 provides elastic force for the arc plate 9, and a buffer component is fixedly connected to the upper outer wall of the protective block 2.

[0031] Reference Figure 1The buffer assembly includes a connecting block 5, which provides support for the protection block 2. The connecting block 5 is T-shaped, and the side wall of the connecting block 5 is slidably connected to the upper inner wall of the outer frame 1. The bottom outer wall of the connecting block 5 is fixedly connected to the upper outer wall of the protection block 2. The lower outer wall of the connecting block 5 is elastically connected to the outer frame 1 through a spring 26. The outer frame 1 is set to protect the line. One end of the spring 26 is fixedly connected to the lower outer wall of the connecting block 5, and the other end of the spring 26 is fixedly connected to the upper inner wall of the outer frame 1. When the protective device vibrates, when the protection block 2 moves downward, the connecting block 5 moves downward to squeeze the spring 26. When it is stationary, the elastic force of the spring 26 is connected to the outer frame 1 through the connecting block 5. Block 1 5 causes the protection block 2 to move upward, and a connecting block 2 3 is fixedly connected to the outer wall at the bottom end of the protection block 2, and the connecting block 23 provides support for the protection block 2, and the connecting block 23 is arranged in a T shape, and the side wall of the connecting block 23 is slidably connected to the inner wall at the bottom end of the outer frame 1, and a spring 3 4 is fixedly connected to the outer wall at the bottom end of the connecting block 23, and the spring 3 4 is used to connect the connecting block 23 and the outer frame 1. When the protective device vibrates, when the protection block 2 moves downward, the connecting block 23 moves downward to squeeze the spring 3 4. When it is stationary, the elastic force of the spring 3 4 moves the protection block 2 upward through the connecting block 2 3, and one end of the spring 3 4 is fixedly connected to the outer wall at the bottom end of the connecting block 23, and the other end of the spring 3 4 is fixedly connected to the inner wall at the bottom end of the outer frame 1.

[0032] Working principle: by moving the transmission line from left to right, the transmission line moves to the right through the harness channel 7. When the transmission line continues to move to the right, the outer wall of the transmission line squeezes the right inner wall of the arc plate 9. The arc plate 9 rotates through the hinge 8, so that the right side of the arc plate 9 expands outward to squeeze the spring 10. When the output line stops moving, the spring 10 releases the elastic force to squeeze the right side of the arc plate 9 inward, so that the right side of the arc plate 9 clamps the transmission line. When the protective device is vibrated, the protection block 2 moves downward to drive the connecting block 1 5 and the connecting block 2 3 to move downward, the connecting block 1 5 squeezes the spring 2 6 downward, and the connecting block 2 3 moves downward to squeeze the spring 3 4. When the protection block 2 stops moving downward, the spring 2 6 drives the protection block 2 to move upward through the connecting block 1 5, and the spring 3 4 lifts the protection block 2 upward through the connecting block 2 3. Under the joint action of the spring 2 6 and the spring 3 4, the protection block 2 returns to its original position.
