DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment:

[0024] As Figures 1-4 shown, a track panel support device with a fine adjustment structure is provided on both sides of the track panel 100, including a coarse adjustment support mechanism 200 and a fine adjustment support mechanism 300. The fine adjustment support mechanism 300 is provided on the coarse adjustment support mechanism 200, and a track panel 100 is provided between the two fine adjustment support mechanisms 300;

[0025] The coarse adjustment support mechanism 200 includes a coarse adjustment lead screw 1 and a coarse adjustment threaded sleeve 2 sleeved on the coarse adjustment lead screw 1. A support foot 3 is provided at the lower end of the coarse adjustment lead screw 1. The coarse adjustment lead screw 1 is rotatably connected to the support foot 3, and the support foot 3 is fixedly connected to the base layer by bolts. A square handle is provided at the top of the coarse adjustment lead screw 1 to facilitate the rotation of the coarse adjustment lead screw 1. When the coarse adjustment lead screw 1 is rotated, since the coarse adjustment threaded sleeve 2 cannot rotate along with it, the coarse adjustment threaded sleeve 2 realizes lifting and lowering.

[0026] The fine adjustment support mechanism 300 is arranged on the coarse adjustment threaded sleeve 2; the fine adjustment support mechanism 300 includes a fine adjustment lead screw 4 and a fine adjustment threaded sleeve 5 sleeved on the fine adjustment lead screw 4. A square handle is provided at the top of the fine adjustment lead screw 4 to facilitate the rotation of the fine adjustment lead screw 4. The fine adjustment threaded sleeve 5 is slidably connected to the coarse adjustment threaded sleeve 2.

[0027] An upper fixing ring 6 and a lower fixing ring 7 are sleeved outside the coarse adjustment threaded sleeve 2. The upper fixing ring 6 is slidably connected to the coarse adjustment threaded sleeve 2, and the lower fixing ring 7 is fixedly connected to the coarse adjustment threaded sleeve 2. A vertical chute 8 is provided on the outer peripheral side of the coarse adjustment threaded sleeve 2, and a vertical slider 9 is provided on the inner side of the upper fixing ring 6. The slider 9 is arranged in the chute 8, so that the upper fixing ring 6 can only slide up and down along the chute 8 and cannot rotate. A fine adjustment lead screw seat 10 is connected to the lower fixing ring 7. The lower end of the fine adjustment lead screw 4 is arranged in the fine adjustment lead screw seat 10, and the fine adjustment lead screw 4 is rotatably connected to the fine adjustment lead screw seat 10. The upper fixing ring 6 is fixedly connected to the fine adjustment threaded sleeve 5, and the track panel 100 is arranged on the fine adjustment threaded sleeve 5. The pitch of the fine adjustment lead screw 4 is smaller than the pitch of the coarse adjustment lead screw 1 to realize fine adjustment when the fine adjustment lead screw 4 is rotated and coarse adjustment when the coarse adjustment lead screw 1 is rotated.

[0028] During use, first rotate the coarse adjustment lead screw 1 to adjust the coarse adjustment threaded sleeve 2 to the required position, and the track panel 100 and the fine adjustment support mechanism 300 move along with it; then rotate the fine adjustment lead screw 4 to make the track panel 100, the fine adjustment threaded sleeve 5, and the upper fixing ring 6 all lift and lower along the chute 8 on the surface of the coarse adjustment threaded sleeve 2 to realize fine adjustment.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
