Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
Example 1
As shown in fig. 1, a gap adjusting and fixing device for a fixing frame includes an adjusting bolt 1 and an adjusting nut 2. Wherein, as shown in fig. 2, the adjusting bolt 1 is a hollow cylinder, and the outer part of the adjusting bolt is provided with an external thread 11; as shown in fig. 3, the adjusting nut 2 is a hollow cylinder, and the inner side of the adjusting nut is provided with an internal thread 21 matching with the external thread 11, and the outer side of the adjusting nut is provided with 4 grooves 23 on the same horizontal plane, so that the adjusting nut 2 can be rotated to adjust the relative positions of the adjusting bolt 1 and the adjusting nut 2.
The bottom of the adjusting bolt 1 and the top of the adjusting nut 2 are respectively provided with a bolt hole 12 and a bolt hole 22, and the diameters of the bolt hole 12 and the bolt hole 22 are not less than the outer diameter of the bolt 4, so that the bolt 4 can pass through the bolt hole 12 and the bolt hole 22 when being assembled.
