During the maintenance of mechanical equipment, the maintenance of the frame or the body itself is often involved. At this time, it is often necessary to lift and level the body itself. Such equipment in the workshop is called a shim, which is a very common mechanism in the workshop. The most common shim is composed of multiple iron plates. However, since mechanical equipment is usually heavy, when lifting it, the height often needs to be adjusted. Ordinary shims are difficult to achieve real-time online adjustment. Therefore, for some machine repair work that requires height adjustment, ordinary shims are difficult to handle. Content of the Utility Model

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. In the description of the present utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is usually placed during use. It is only for the convenience of describing the present utility model or simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0017] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and limited, the terms "arrangement", "installation", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0018] See Figures 1 to 4 , the present utility model is a novel adjustable shim mechanism, having a bottom plate 5. Two fixed shims 6 arranged side by side front and back are provided on the bottom plate. The upper end surfaces of the two fixed shims are set as wedge-shaped inclined surfaces. A movable shim 7 is provided on the two fixed shims. The upper end surface of the movable shim is horizontal. Two wedge-shaped track grooves are provided at the bottom of the movable shim. The two wedge-shaped track grooves slide along the wedge-shaped inclined surfaces on the corresponding fixed shims; further, in the present utility model, the movable shim is formed by assembling and welding an upper panel 11, side plates 13, and front and rear leg plates 10. Wedge-shaped track grooves are respectively provided at the bottoms of the front and rear leg plates; further, a U-shaped notch 8 is provided on the upper panel in the present utility model; a fixed plate 2 is further provided on the bottom plate on one side of the movable shim. A vertically arranged U-shaped notch groove 12 is provided at the middle position of the fixed plate. A power connecting rod 4 is clamped in the U-shaped notch groove. An external thread section is provided on the power connecting rod. The external thread section is threadedly connected to the side part of the movable shim. Two spaced annular clamping plates 3 are provided near the tail of the power connecting rod. The two annular clamping plates are respectively clamped on the two side walls of the fixed plate and can realize the up and down movement of the power connecting rod in the U-shaped notch groove; a rotating head 1 is further provided at the tail end of the power connecting rod. Further, in the present utility model, the wedge-shaped track groove is an inverted U-shaped track groove structure 9, and the whole inverted U-shaped track groove structure is obliquely arranged and slidably matched with the wedge-shaped inclined surface on the corresponding fixed shim.
[0019] Further, in this embodiment, the rotating head is a hexagonal nut head or a flat head. Further, in the present utility model, the bottom plate is made of a rectangular steel plate, and the fixed shim and the movable shim are both made of steel plates.
[0020] In the present utility model, two annular clamping plates are arranged at intervals at the tail of the power connecting rod, and the power connecting rod is just clamped in the U-shaped notch groove by the two annular clamping plates, but the up-and-down movement of the power connecting rod is not affected; in practical applications, when a shim is needed, first place the whole mechanism at the bottom of the relevant machinery, place the mechanical maintenance part on the movable shim, and then adjust the height of the movable shim. At this time, use a tool such as a wrench to twist the rotating head, so that the external thread on the power connecting rod rotates accordingly, which will drive the movable shim to slide along the wedge-shaped inclined plane on the fixed shim, realizing the adjustment of the height of the movable shim; as the height of the movable shim rises and falls, the power connecting rod will also move up and down in the U-shaped notch groove. At the same time, since the two annular clamping plates are clamped on the left and right sides of the U-shaped notch groove for limiting, the power connecting rod can only move up and down normally.
[0021] In the present utility model, since the power connecting rod drives the lifting of the movable shim by means of an external thread, even if the machinery on the movable shim is very heavy, it can bear the weight and perform fine adjustment in height.
[0022] The present utility model is an improved design of a common shim mechanism, enabling the mechanism of the present utility model to achieve real-time height adjustment during actual use. The adjustment operation is quick, convenient, time-saving and labor-saving. Compared with common shims, the use efficiency is higher, and it has good practical use and popularization value.
