Referring to FIG. 7, when the parallelism of the rails 9 is not good and the distance between them is different, one of the rails 9 will first push the second rollers 533 on the left side, due to the first elastic members 541 The spring constant is greater than the spring constant of the second elastic members 542, the second elastic members 542 on the left side will be compressed first, and the sliding will be pushed when the second elastic members 542 are compressed to its limit Seat 52, so that the sliding seat 52 moves to the left to shorten the distance D and compress the first elastic members 541, thereby generating more The displacement is large. Therefore, in the case of poor parallelism of the rails 9, the rail sliding mechanisms 300 can still move smoothly following the rails 9.

Based on the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. By compressing the amount of deformation generated by the elastic group 54 to enable the sliding The seat 52 is displaced left and right relative to one of the rails 9 and moves forward and backward following one of the rails 9, thereby avoiding the problems of jamming and inability to slide smoothly due to poor parallelism of the rails 9.

2. First, through the amount of deformation of the second elastic members 542 of each elastic group 54 so that each track sliding mechanism 300 can move in accordance with the tracks 9, when the parallelism of the tracks 9 is different, then In accordance with the deformation amount of the first elastic members 541, a larger displacement margin can be generated, and the rail sliding mechanisms 300 can still move smoothly following the rails 9.

Referring to FIG. 8, it is a second embodiment of the ceiling type protective cover of the present invention. The second embodiment is similar to the first embodiment. The main difference is that the elastic group 54' omits the four pairs of second Elastic member 542 (see Figure 7).

With the amount of deformation generated by the first elastic members 541, the second embodiment can still overcome the problem of jamming due to the poor parallelism of the rails 9. Refer to FIG. 9, which is a third embodiment of the ceiling type protective cover of the present invention. The third embodiment is similar to the first embodiment. The main difference is that the side wall 513 of the coupling seat 51 abuts against the One of the ear walls 524 of the sliding seat 52.

The elastic group 54" omits the first elastic members 541 (see FIG. 7). With the amount of deformation generated by the second elastic members 542, the third embodiment can still overcome the parallelism of the rails 9 Bad and stuck problem.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to Within the scope covered by the patent of the present invention.
