Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "one side", "the other side", "both sides", "between", "middle part", "upper end", "lower end", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, 2 and 3, the belt pulley device with adjustable spacing of the present invention has a belt pulley 1, an open slot 2 is formed on the peripheral side wall of the belt pulley 1, a plurality of waist-shaped holes 3 are vertically formed on the bottom end surface of the open slot 2 along the circumferential direction, and a spacing strip 4 is fixed in each waist-shaped hole 3; a belt groove 5 is formed between the limiting strip 4 and the side wall of the open groove 2 or the limiting strip 4, and a belt is embedded in the belt groove 5.
Wherein, the section of the open slot 2 is in an inverted trapezoidal structure with a big upper end opening and a small lower end opening. Spacing 4 is the arc structure, and 4 cross-sections of spacing are trapezium structure. The lower end of the limiting strip 4 is vertically provided with a fixing rod 6, and the fixing rod 6 penetrates through the waist-shaped hole 3 and then is fixed through a fastening bolt 7. The fixed cover 8 that sets up in 1 middle part of belt pulley, fixed cover 8 outside is through connecting rod 9 connection belt pulley 1.
