Example one

As shown in figures 1 and 2, the staggered and overlapped connection and adjustment structure for the guide rail of the embodiment of the invention comprises two guide rails 1 which are staggered and overlapped, two grooves 1-1 are arranged at two sides of the upper end of each guide rail 1, pulley grooves 1-3 are arranged at the lower end surface of each guide rail 1, pulleys 3 are arranged on the pulley grooves 1-3, a slightly wide connecting plate 2 is arranged at the end of each staggered and overlapped guide rail 1, the connecting plate 2 is movably buckled in the grooves 1-1 at two sides of each guide rail 1 to connect the staggered and overlapped guide rails 1 together, the upper end surface of each guide rail 1 is a plane 1-2, the connecting end of each connecting plate 2 is also a plane 2-2, specifically, a convex rib 2-1 which is bent towards the direction of each groove 1-1 and corresponds to the width of each guide rail 1 is arranged on each connecting plate 2, the number of the convex ribs 2-1 corresponds to the number of, the convex rib 2-1 is inserted into the groove 1-1 to connect two or more staggered overlapped guide rails 1. The convex ribs 2-1 on the connecting plate are in clearance connection with the grooves 1-1, so that the two guide rails 1 can slide relative to the connecting plate 2, and the purpose of adjusting the overlapping length between the guide rails 1 is achieved.

When the structure of the utility model is installed, firstly, the convex rib 2-1 of the connecting plate 2 is inserted into the groove 1-1 from the end part of the guide rail 1 at the overlapping end, and then the end part of the guide rail is plugged by the end cover, thus the installation is convenient and rapid.

Example two

Compared with the previous embodiment, under the condition that other structures are not changed, the matched connection of the convex rib 2-1 and the groove 1-1 can also adopt a mode that one is in clearance fit and the other is in tight fit, so that the guide rails 1 which are staggered and overlapped can be fixed and can not slide, and the other can slide, thereby achieving the purpose of adjusting the overlapping length between the guide rails 1.

As another embodiment, in the first or second embodiment, the connecting plate may be two or more; the number of guide rails may also be three or four. As shown in fig. 3, when there are three guide rails, the guide rail 1 and the connecting plate 2 in the middle are movably connected in a sliding manner, and the guide rails 1 and the connecting plate 2 on both sides may be movably connected in a sliding manner or in a tight fit connection.

Therefore, the number of the grooves 1-1 on the side part of the guide rail is not limited to one, two or three grooves can be adopted, and two or three corresponding convex ribs 2-1 of the connecting plate are also adopted.

The above detailed description explains the essence of the present invention in detail, but the scope of the present invention should not be limited thereto. Obviously, many modifications and adaptations can be made by one of ordinary skill in the art in light of the present disclosure, and it is intended to cover such modifications and adaptations as fall within the scope of the present invention.
