Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-7 , a locking device for a bridge cover plate, including a bridge frame 1 and a cover plate 2. An assembly groove 3 is opened in the side structure at the top of the cover plate 2. An inner threaded sleeve plate 4 aligned with the assembly groove 3 is installed on the surface of the side of the bridge frame 1. A threaded rod 5 is threadedly connected inside the inner threaded sleeve plate 4, and one end of the threaded rod 5 penetrates and is clamped inside the assembly groove 3;

[0027] For the convenience of subsequent replacement and maintenance, both the front and rear ends of the inner threaded sleeve plate 4 are in the form of extended plates, and the extended plate structures are installed with screws between the corresponding side structures of the bridge frame 1;

[0028] One end of the threaded rod 5 is fixedly connected with a locking curved block 6 that can be movably sleeved in the assembly groove 3. Buffer components 7 are sleeved inside both ends of the locking curved block 6. The bottom of both ends of the locking curved block 6 is in fit connection with the top surface of the cover plate 2, and the bottom of the buffer component 7 is in buffer connection with the top surface of the cover plate 2;

[0029] The locking curved block 6 has a key slot 10 and a receiving slot 11 at both ends thereof, and the key slot 10 and the receiving slot 11 are spatially connected and form a space for receiving the set buffer component 7. The buffer component 7 includes an inverted L-shaped rod 71, a transition rod 72, a damping block 73 and a buffer spring 74. The inverted L-shaped rod 71 is clamped in the key slot 10 and can be offset with the top of the key slot 10. The two ends of the transition rod 72 are respectively connected between the bottom of the inverted L-shaped rod 71 and the top of the damping block 73. The two ends of the buffer spring 74 are respectively connected between the bottom of the inverted L-shaped rod 71 and the top of the damping block 73. The ends are respectively connected between the bottom of the inverted L-shaped rod 71 and the top of the damping block 73. The assembly formed by the transition rod 72, the damping block 73 and the buffer spring 74 can be completely fitted inside the storage groove 11. The buffer spring 74 can move the damping block 73 and the transition rod 72 to the outside of the bottom of the storage groove 11 in a non-compressed state. The buffer component 7 is linked to the locking operation of the locking curved block 6, and the vibration suffered by the locking curved block 6 during use is buffered and protected, thereby improving the stable locking effect of the overall device.

[0030] The bottom end of the threaded rod 5 is connected to a linkage rod 8, and a decompression component 9 aligned with the linkage rod 8 is installed at the bottom of the internal threaded sleeve 4. The linkage rod 8 includes a linkage sleeve 81 and a T-shaped pressure rod 82.

The decompression component 9 is mainly composed of a supporting sleeve and a pressure sensor installed in the middle part of the supporting sleeve. The pressure sensing surface of the pressure sensor is movably connected to the bottom end of the T-shaped pressure rod 82. The linkage rod 8 and the decompression component 9 work in combination. In the subsequent process of locking the bridge frame 1 and the cover plate 2 by the locking curved block 6, the threaded rods 5, and 41, the operating status of the threaded rod 5 is real-time pressure detection, and then timely detection is made when the locking curved block 6 or the threaded rod 5 moves, thereby eliminating safety hazards.

[0031] Working principle: Embodiment 1:

[0032] The bridge 1 and the cover plate 2 are locked normally. The cover plate 2 is first covered on the top of the bridge 1. During the assembly of the cover plate 2 and the bridge 1, the assembly groove 3 and the top structures of the locking curved block 6 and the threaded rod 5 are synchronously assembled and made way. After the assembly of the cover plate 2 and the bridge 1 is completed, the tops of the locking curved block 6 and the threaded rod 5 have also moved to the top of the cover plate 2.

[0033] Next, the locking block 6 is twisted to make the threaded rod 5 and the internal threaded sleeve plate 4 threadedly engaged, until the locking block 6 is in an inclined but fully contacted manner with the top surface of the cover plate 2, and a locking pressure is applied between the bridge 1 and the cover plate 2 to ensure the stability of the bridge 1 and the cover plate 2 during the combined use;

[0034] During the use of the overall device, the damping block 73 and the buffer spring 74 at the temporal part of the buffer component 7 jointly buffer and protect the use vibration suffered by the locking curved block 6 at its position. Embodiment 2:

[0035] For the limited-position insurance locking of the bridge frame 1 and the cover plate 2, first cover the cover plate 2 on the top of the bridge frame 1. During the sleeving process of the cover plate 2 and the bridge frame 1, the assembly groove 3 is synchronously sleeved and displaced with the top structures of the locking curved block 6 and the threaded rod 5. After the cover plate 2 and the bridge frame 1 are combined, the tops of the locking curved block 6 and the threaded rod 5 have also moved to the top of the cover plate 2;

[0036] Then, rotate the locking curved block 6 to make the threaded rod 5 engage with the internal thread sleeve plate 4 in a threaded manner until the locking curved block 6 applies a locking pressure between the bridge frame 1 and the cover plate 2 in a way that the buffer component 7 at one end of itself moves to the side surface of the cover plate 2 to limit the fall. Thus, using one buffer component 7 as the insurance for the rotational limit of the locking curved block 6 fully ensures the stability during the combined use of the bridge frame 1 and the cover plate 2;

[0037] During the use of the overall device, the damping block 73 and the buffer spring 74 at the temporal part of the buffer component 7 jointly buffer and protect the use vibration suffered by the locking curved block 6 at its position. Embodiment 3:

[0038] For the normal locking of the bridge frame 1 and the cover plate 2 and the pressure detection, first cover the cover plate 2 on the top of the bridge frame 1. During the sleeving process of the cover plate 2 and the bridge frame 1, the assembly groove 3 is synchronously sleeved and displaced with the top structures of the locking curved block 6 and the threaded rod 5. After the cover plate 2 and the bridge frame 1 are combined, the tops of the locking curved block 6 and the threaded rod 5 have also moved to the top of the cover plate 2;

[0039] Then, rotate the locking curved block 6 to make the threaded rod 5 engage with the internal thread sleeve plate 4 in a threaded manner until the locking curved block 6 applies a locking pressure between the bridge frame 1 and the cover plate 2 in a way that it is inclined but fully contacts the top surface of the cover plate 2, ensuring the stability during the combined use of the bridge frame 1 and the cover plate 2;

[0040] During the use of the overall device, the damping block 73 and the buffer spring 74 at the temporal part of the buffer component 7 jointly buffer and protect the use vibration suffered by the locking curved block 6 at its position;

[0041] During the locking process of the threaded rod 5 and the internally threaded sleeve plate 4, the linkage rod 8 synchronizes the movement of the threaded rod 5 and presses against the pressure sensor inside the pressure reduction component 9 after the locking of the threaded rod 5 is completed, causing the pressure sensor to generate pressure data and transmit it to the background device. When there is a significant change in the pressure data during the subsequent use of the overall device, it indicates that the locking state between the locking block 6 and the threaded rod 5 has changed, and timely maintenance is required.
