[0029] See also Figure 6The locking structure 5 includes a C-shaped seat 501 movably embedded in the upper end of the support column 2, and the C-shaped seat 501 can move up and down inside the support column 2. A pin rod 2 502 is fixedly embedded at the center of the lower end of the C-shaped seat 501. A spring 2 503 is movably sleeved on the outer side of the pin rod 2, and the two ends of the spring 2 503 are movably abutted against the support column 2 and the C-shaped seat 501 respectively. The spring 2 503 can drive the C-shaped seat 501 to move upward. A plurality of triangular tooth grooves 504 distributed at equal distances are opened on the right side of the C-shaped seat 501. Two symmetrically distributed positioning rods 505 are fixedly embedded on the right side of the C-shaped seat 501. The positioning rod 505 can prevent the C-shaped seat 501 from rotating, and the positioning rod 505 is close to the lower end of the C-shaped seat 501.

[0030] See also Figure 4 , Figure 6 The positioning rod 505 is in sliding contact with the support column 2 through a limiting straight groove. The buffer structure 6 includes a piston 601 fixedly mounted on the lower end of the pin rod 502. The piston 601 is made of wear-resistant rubber. The outer side of the piston 601 is movably sleeved with a semi-enclosed sleeve 602, and the semi-enclosed sleeve 602 is fixedly embedded in the interior of the support column 2. Two symmetrically distributed one-way valves 603 are fixedly mounted on the outer side of the semi-enclosed sleeve 602 near its lower end. Two symmetrically distributed exhaust holes 604 are also provided on the outer side of the semi-enclosed sleeve 602 near its lower end. The exhaust holes 604 can discharge the gas in the semi-enclosed sleeve 602. The deceleration assembly 7 includes a cam 701 installed inside the support column 2, and the cam 701 is rotatably connected to the support column 2 through a positioning shaft 702.

[0031] See also Figure 4 A flexible pad 703 is fixedly sleeved on the outer side of the cam 701, and the flexible pad 703 is movably abutted against the C-shaped seat 501 through the triangular tooth groove 504. The flexible pad 703 is made of silicone material. Two symmetrically distributed coil springs 704 are fixedly sleeved on the outer side of the positioning shaft 702. The outer end of the coil spring 704 is fixedly connected to the support column 2. A limited rotation groove 705 is provided inside the support column 2 at the corresponding installation location of the cam 701. The limited rotation groove 705 can limit the rotation angle of the cam 701. The lower end of the C-shaped seat 501 is movably abutted against two symmetrically distributed support blocks 8, and the connection between the support block 8 and the support column 2 is a fixed connection, and the support block 8 can support the C-shaped seat 501.

[0032] Working principle: When the cable drum shaft rolls into the C-shaped seat 501 through the diagonal support rod 3, the C-shaped seat 501 will move downward under the action of the gravity of the cable drum. When the pin rod 2 502 moves downward with the C-shaped seat 501, the piston 601 can be driven to move downward inside the semi-enclosed sleeve 602. Since the semi-enclosed sleeve 602 takes in air through the one-way valve 603 and exhausts air through the exhaust hole 604, when the piston 601 moves downward to squeeze the gas inside the semi-enclosed sleeve 602 and discharge it from the exhaust hole 604, the exhaust speed of the semi-enclosed sleeve 602 is slow, which can slow down the downward movement speed of the C-shaped seat 501.

[0033] At the same time, since the cam 701 is blocked by the limit groove 705 and cannot rotate counterclockwise, during the downward movement of the C-shaped seat 501, the flexible pad 703 on the outside of the cam 701 contacts and rubs with the C-shaped seat 501 through the triangular tooth groove 504, which can further increase the downward movement resistance of the C-shaped seat 501, thereby further slowing down the downward movement of the C-shaped seat 501, preventing the C-shaped seat 501 from moving downward and hitting the support block 8 under the gravity of the optical cable drum, and preventing the pay-off device from generating large vibrations when installing the optical cable drum, which can effectively extend the service life of the pay-off device;

[0034] After the optical cable reel is laid out, the operator lifts the optical cable reel shaft upward, and at this time, spring 2 503 will drive the C-type seat 501 to move up and reset. During the reset process, the semi-enclosed sleeve 602 takes in air faster through the one-way valve 603, and the cam 701 can rotate clockwise through the limit rotation groove 705, so that the cam 701 will not affect the upward movement of the C-type seat 501, thereby facilitating the rapid upward movement and reset of the C-type seat 501.

[0035] Example 2: Please refer to Figure 3 This embodiment further illustrates the first embodiment. The diagonal brace rod 3 is used to assist the rotating shaft of the optical cable drum to enter the locking structure 5. Two symmetrically distributed diagonal brace rods 3 are fixedly installed on the left sides of the two support columns 2.

[0036] In the present embodiment: during the process of installing the optical cable drum shaft into the C-shaped seat 501, personnel place the optical cable drum shaft on the upper end of the diagonal support rod 3, and then roll the optical cable drum shaft upward along the inclined surface of the diagonal support rod 3 until the optical cable drum shaft rolls into the C-shaped seat 501, and the diagonal support rod 3 assists the optical cable drum to roll into the locking structure 5, thereby avoiding the need to manually lift the optical cable drum during the installation of the optical cable drum, effectively reducing the physical exertion of personnel.

[0037] Example 3: Please refer to Figure 3This embodiment further explains the second embodiment. The anti-drop assembly 4 includes a stopper 401 which is movably embedded in the upper end of the diagonal support rod 3 and can move up and down. An inclined surface is provided at the upper left end of the stopper 401. The stopper 401 can prevent the optical cable drum shaft from rolling to the left. A pin rod 402 is fixedly embedded at the center of the lower end of the stopper 401. A spring 403 is movably sleeved on the outer side of the pin rod 402.

[0038] See also Figure 5 The two ends of the spring 403 are respectively movably abutted against the diagonal support rod 3 and the stopper 401. The diagonal support rod 3 facilitates the auxiliary optical cable reel to enter the locking structure 5. The lower end of the pin rod 402 is fixedly connected with an anti-slip block 404, and the anti-slip block 404 is located on the lower side of the diagonal support rod 3.

[0039] In the present embodiment, when the rotating shaft of the optical cable drum rolls upward on the inclined surface of the diagonal support rod 3, the rotating shaft of the optical cable drum will squeeze the stopper 401 through the inclined surface of the stopper 401, and the stopper 401 will be pressed into the interior of the diagonal support rod 3. When the rotating shaft of the optical cable drum rotates to disengage from the stopper 401, the stopper 401 will move upward and reset under the drive of the spring 403. At this time, the stopper 401 will block the rotating shaft of the optical cable drum, which can effectively prevent the rotating shaft of the optical cable drum from rolling downward through the inclined surface of the diagonal support rod 3 during the installation of the optical cable drum, making it easier to install the optical cable drum.
