The overall idea is as follows:
[0026] In view of the problems existing in the prior art, the utility model provides a throat hoop with strong fastening force, which comprises a hoop band 1, the external thread connection of the hoop band 1 is provided with an adjusting screw 2, the external rotation connection of the hoop band 1 is provided with a connecting plate 3, the connecting plate 3 is L-shaped, the external surface of the connecting plate 3 is provided with a mounting hole 4, the external surface of the adjusting screw 2 is provided with a fixing mechanism, the fixing mechanism comprises a limiting shell 5, a threaded rod 6, a rotating block 7, a connecting hole 8, a fixing block 9 and a pulling plate 10, the limiting shell 5 is clamped on the external surface of the adjusting screw 2, the threaded rod 6 is threadedly connected to the external surface of the limiting shell 5, the rotating block 7 is rotationally connected to the external surface of the threaded rod 6, the rotating block 7 is composed of two rectangular blocks of different sizes, the connecting hole 8 is provided on the external surface of the rotating block 7, the fixing block 9 is slidably connected to the internal surface of the connecting hole 8, and the pulling plate 10 passes through the external surface of the rotating block 7 and extends to the connecting hole 8. The end is fixedly installed on the outside of the fixing block 9, the connecting plate 3 is clamped in the inside of the connecting hole 8, and the fixing block 9 is slidably connected to the inside of the mounting hole 4. By setting the connecting plate 3 and cooperating with the limiting shell 5, when the adjusting screw 2 is rotated to tighten the hoop 1, the limiting shell 5 is clamped on the outside of the adjusting screw 2. At this time, the rotating block 7 is rotated upward, and the connecting plate 3 is rotated downward to make the connecting plate 3 enter the inside of the connecting hole 8. At this time, the threaded rod 6 is rotated so that the end of the threaded rod 6 and the limiting shell 5 fix the rotating block 7. At this time, the pulling plate 10 is pushed to drive the fixing block 9 to make the fixing block 9 enter the inside of the mounting hole 4. At this time, the rotating block 7 is connected to the connecting plate 3. At this time, the distance between the limiting shell 5 and the hoop 1 is fixed, and the clamped adjusting screw 2 cannot be rotated, thereby reducing the probability of loosening or displacement of the adjusting screw 2 when the object bound by the throat hoop vibrates, thereby ensuring that the fastening force of the throat hoop is strong.
[0027] An installation shaft 11 is fixedly installed on the outside of the hoop 1, and the connecting plate 3 is rotatably connected to the outside of the installation shaft 11. The installation shaft 11 is a structure for the connection plate 3 to rotate. An opening 12 is opened on the outside of the rotating block 7. The rotating block 7 is rotatably connected to the outside of the threaded rod 6 through the opening 12, which is a movable structure of the rotating block 7.
[0028] The interior of the connecting hole 8 is provided with a built-in groove 13, and the fixing block 9 is slidably connected to the interior of the built-in groove 13, so that when the connecting plate 3 enters the connecting hole 8, the fixing block 9 is stored. The interior of the built-in groove 13 is fixedly connected with two springs 14, and the fixing block 9 is fixedly connected to the outside of the two springs 14 to provide support for the fixing block 9. A connecting rope 15 is arranged on the outside of the pull plate 10, and a fixing ring 16 is fixedly installed on the outside of the pull plate 10. The connecting rope 15 is tied to the outside of the fixing ring 16 for easy pulling of the pull plate 10. By setting the built-in groove 13 and cooperating with the spring 14, when the connecting plate 3 needs to enter the connecting hole 8, the connecting rope 15 is pulled to drive the pull plate 10 to make the fixing block 9 completely enter the interior of the built-in groove 13. At this time, the spring 14 is compressed, and the connecting plate 3 is pressed to make the connecting plate 3 enter the connecting hole 8. At this time, the connecting rope 15 is released, and under the action of the spring 14, the fixing block 9 moves toward the inside of the mounting hole 4. At this time, the installation of the connecting plate 3 is completed, which is convenient for the staff to move the fixing block 9, thereby reducing the difficulty of the staff to fix it.
[0029] Working principle:
[0030] The first step is to set the connecting plate 3 and cooperate with the limiting shell 5. When the adjusting screw 2 is rotated to tighten the hoop 1, the limiting shell 5 is clamped on the outside of the adjusting screw 2. At this time, the rotating block 7 is rotated upward, and the connecting plate 3 is rotated downward to make the connecting plate 3 enter the inside of the connecting hole 8. At this time, the connecting rope 15 is pulled to drive the pulling plate 10 to make the fixing block 9 completely enter the inside of the built-in groove 13. At this time, the spring 14 is compressed. At this time, the connecting plate 3 is pressed to make the connecting plate 3 enter the connecting hole 8. At this time, the connecting rope 15 is loosened. Under the action of the spring 14, the fixing block 9 moves to the inside of the mounting hole 4;
[0031] In the second step, the threaded rod 6 is rotated so that the end of the threaded rod 6 and the limiting shell 5 fix the rotating block 7. At this time, the rotating block 7 is connected to the connecting plate 3. At this time, the distance between the limiting shell 5 and the hoop 1 is fixed, so that the clamped adjusting screw 2 cannot rotate. At this time, the clamped adjusting screw 2 cannot rotate, thereby reducing the probability of the adjusting screw 2 loosening or shifting when the object bound by the throat hoop vibrates, thereby ensuring that the fastening force of the throat hoop is strong.
[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
