[0024] The position of the mounting frame 101 can be quickly adjusted by reeling in and out the connecting steel rope 205, thereby adjusting the height of the lamp 102 to facilitate inspection and maintenance by the staff.

[0025] See also Figure 1-5A rotating block 201 is arranged inside the installation cavity, and winding rollers 202 are arranged at both ends of the rotating block 201. The ends of the two connecting steel ropes 205 away from the slider 104 are wound on the surfaces of the adjacent winding rollers 202; the other end of one of the winding rollers 202 is rotatably connected to the inner wall of the installation cavity, and the end of the other winding roller 202 away from the rotating block 201 passes through the pillar 1 and is fixedly connected to the turntable 203. A limiting hole 204 distributed in a ring shape with the winding roller 202 as the center is opened on one side of the pillar 1; a hand wheel 206 is arranged on the surface of the turntable 203, and the hand wheel The inner wall of 206 is slidably connected with a sliding plate 212, and the surface of the sliding plate 212 is fixedly connected with a connecting rod 210, and the other end of the connecting rod 210 passes through the hand wheel 206 and the rotating disk 203 in sequence and is fixedly connected with a limiting block 207, and the other end of the limiting block 207 extends to the inside of the adjacent limiting hole 204; the surface of the sliding plate 212 is fixedly connected with a spring 211, and the other end of the spring 211 is fixedly connected with the inner wall of the hand wheel 206; a storage cavity is opened on the side of the rotating disk 203 close to the pillar 1, and the limiting block 207 matches the storage cavity;

[0026] By pulling the hand wheel 206, the hand wheel 206 is moved away from the rotating disk 203 and the spring 211 is compressed. Then, under the action of the spring 211, the sliding plate 212 is pushed to drive the connecting rod 210 and the limit block 207 to move synchronously. In this process, the limit block 207 is driven to retract into the interior of the storage cavity, so that the limit block 207 is separated from the limit hole 204, and the limit on the winding roller 202 can be released. At this time, the rotating disk 203 can be driven to rotate by the hand wheel 206 to achieve the effect of unwinding the connecting steel rope 205. Under the action of gravity, the mounting frame 101 can drive the lamp 102 to slowly move down along the surface of the guide rod 103 for the convenience of maintenance by the staff. After the maintenance is completed, the winding roller 202 is rotated in the opposite direction to rewind the connecting steel rope 205 to achieve the reset of the position of the lamp 102;

[0027] When the position of the lamp 102 needs to be limited, the hand wheel 206 is pushed close to the turntable 203 to release the squeeze on the spring 211. The spring 211 can quickly drive the limit block 207 to reset, and the initial insertion into the limit hole 204 is achieved to achieve the initial limit, so as to avoid the self-rotation of the winding roller 202 during the reset process, so as to facilitate the subsequent pushing of the hand wheel 206 and the turntable 203 to fit together to ensure that the limit block 207 is connected to the limit hole 204 in place, and the operation is simple.

[0028] See also Figure 1-5 A knob 209 is provided on the surface of the turntable 203, one end of the knob 209 is fixedly connected to the limit screw 208, and the other end of the limit screw 208 passes through the turntable 203 and the connecting rod 210 in sequence and is threadedly connected to the inner wall of the turntable 203;

[0029] When it is necessary to unwind the connecting steel rope 205 on the winding roller 202, it is necessary to first rotate the knob 209 to drive the limit screw 208 to separate from the connecting rod 210, thereby releasing the limiting effect on the connecting rod 210, and then the limit block 207 can be driven to separate from the limit hole 204 through the connecting rod 210. This part of the operation can avoid the height of the lamp 102 from falling due to misoperation, and after the lamp 102 is lifted to the required position, it can be determined whether the limit block 207 and the limit hole 204 are connected in place by installing the limit screw 208.

[0030] Working principle: by pulling the hand wheel 206, the hand wheel 206 is moved away from the turntable 203 and the spring 211 is compressed, and then the sliding plate 212 is pushed under the action of the spring 211 to drive the connecting rod 210 and the limit block 207 to move synchronously. In this process, the limit block 207 is driven to shrink to the inside of the storage cavity, so that the limit block 207 is separated from the limit hole 204, and the limit on the winding roller 202 can be released. At this time, the turntable 203 can be driven to rotate by the hand wheel 206 to achieve the effect of unwinding the connecting steel rope 205. Under the action of gravity, the mounting frame 101 can drive the lamp 102 to slowly move down along the surface of the guide rod 103 for the convenience of maintenance by the staff. After the maintenance is completed After completion, the position of the lamp 102 can be reset by rotating the winding roller 202 in the opposite direction to rewind the connecting steel rope 205. The operation is simple. At the same time, when unwinding the connecting steel rope 205 on the winding roller 202, it is necessary to first rotate the knob 209 to drive the limit screw 208 to separate from the connecting rod 210, so as to release the limiting effect of the connecting rod 210. The limit block 207 can be driven to separate from the limit hole 204 through the connecting rod 210. This part of the operation can avoid the height of the lamp 102 from falling due to misoperation, and after the lamp 102 is lifted to the desired position, it can be determined whether the limit block 207 and the limit hole 204 are connected in place by installing the limit screw 208.
