Detailed Description

The technical solutions of the present utility model will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", "vertical", "horizontal", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements to be referred to must have a specific direction, construct and operate in the specific direction, and thus are not to be construed as limiting the present utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Fig. 1-6 are schematic structural diagrams of a plate-type pulley with a wide application range according to a preferred embodiment of the present utility model, in this embodiment, since the pulley does not have an adjustable function between two transverse wheels, so that the adaptability is not high, and therefore, the plate-type pulley with a wide application range includes a steel rail 1, a plurality of connecting shafts 5 are fixedly connected to left and right sides of the pulley 2 respectively by arranging the pulley 2 in the steel rail 1, a shaft sleeve 3 is sleeved on the connecting shafts 5, a function of extending and shortening is realized by matching the connecting shafts 5 with the shaft sleeve 3, a fixed block 8 is fixedly connected to one end of the shaft sleeve 3, a bearing 14 is sleeved on the fixed block 8, and a pulley 4 is sleeved on the bearing 14 so as to realize that the pulley can slide in the steel rail 1.

In this embodiment, the movable opening 9 is formed on the connecting shaft 5, the fixed plate 13 is fixedly installed in the connecting shaft 5 to play a role of supporting a spring, the first positioning block 12 is fixedly connected to the fixed plate 13 to play a role of fixing the spring to prevent the spring from deviating when being extruded, one end of the spring 11 is sleeved on the first positioning block 12, the locking block 6 is fixedly connected to the top of the spring 11 to realize the retracting and extending functions of the locking block 6, and the locking block 6 moves at the movable opening 9.
