The first rib plate 23 is symmetrically arranged on both sides of the first bracket 22, and the bottom edge of the first rib plate 23 is connected to the upper edge of the guide rail 21, and the side edge of the first rib plate 23 is connected to the side edge of the bracket. The bracket assembly 12 is symmetrically fixed on both sides of the waterproof groove 11, and forms a sliding pair with two sets of parallel guide rails 21. The guide rail 21 is connected to the forklift by the vertically mounted first bracket 22, and the first rib plates 23 on both sides adopt a triangular reinforcement structure, so that the guide rail 21 and the bracket form a rigid whole. When the bracket assembly 12 slides longitudinally along the guide rail 21, the waterproof groove 11 is driven to translate synchronously through mechanical linkage to realize the position adjustment function. At the same time, the symmetrical layout of the guide rail 21 and the support of the first rib plate 23 ensure that the sliding process is stable and without deflection.

[0078] In this embodiment, the specific structure of the bracket assembly 12 can be various structures known to those skilled in the art, provided that the structure drives the waterproof groove 11 to move on the guide rail assembly 2. In one example of the present invention, Figure 5 As shown, the bracket assembly 12 includes a second bracket 121, a mounting shaft 122, a bearing 123 and a vertical plate 124. Among them, the second bracket 121 is arranged on the upper surface of the waterproof groove 11, and the bottom is fixedly connected to the waterproof groove 11. The mounting shaft 122 is symmetrically arranged on the side of the second bracket 121 away from the guide rail 21 along the horizontal direction of the second bracket 121. The bearing 123 is sleeved on the mounting shaft 122, and the bearing 123 rolls along the track of the guide rail 21 to drive the waterproof groove 11 to move horizontally. Furthermore, in order to install the end of the shaft 122 away from the guide rail 21, a shoulder is provided, and the shoulder and the bearing 123 are interference fit, which is used to axially position the bearing 123 to prevent it from moving sideways. The second bracket 121 is fixed to the upper surface of the waterproof groove 11 through the bottom, and the bearing 123 is sleeved on the horizontally symmetrical mounting shaft 122, and the bearing 123 is embedded in the track of the guide rail 21 and rolls. When external force acts, the bearing 123 rolls along the guide rail 21 to drive the second bracket 121 and the waterproof groove 11 to slide as a whole. The vertical plate 124 stands vertically at the bottom of the second bracket 121, forming a clearance fit with the side wall of the guide rail 21, limiting lateral deviation during sliding and ensuring a stable moving trajectory.

[0079] In order to further limit the relative position of the guide rail 21 and the second bracket 121, in this embodiment, a through hole is provided on the top of the vertical plate 124, and a fixing hole corresponding to the through hole is provided on the guide rail 21, and the fixing hole and the through hole are connected by bolts.
