Detailed Description
In order that those skilled in the art will better understand the technical solution of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and embodiments.
An adjustable positioning wheel as shown in fig. 1-3 comprises a fixed plate 1, an eccentric mounting shaft 2 arranged on the fixed plate 1, and a positioning pulley 3 arranged on the eccentric mounting shaft 2. Preferably, a rubber anti-slip layer 6 is arranged outside the positioning pulley 3, and the rubber anti-slip layer 6 can play a role in buffering and anti-slip, so that the positioning pulley 3 can move more smoothly. Eccentric installation axle 2 has main shaft 21 and fixes first connecting axle 22 and second connecting axle 23 at main shaft 21 both ends respectively, first connecting axle 22 is connected on fixed plate 1 and can rotate relative fixed plate 1, second connecting axle 23 passes through the bearing and is connected with positioning pulley 3 rotation, just first connecting axle 22 and the setting of second connecting axle 23 disalignment. The fixing plate 1 is provided with a fixing hole 11, and the fixing hole 11 is preferably a circular through hole or an arc-shaped through hole. The fixed plate 1 is used for connecting the movable door, and the design of the circular through hole and the circular arc-shaped through hole enables the connection mode of the fixed plate 1 and the movable door to be more various.
Preferably, the fixing plate 1 is provided with an installation platform 4 protruding upwards, the installation platform 4 is provided with an installation hole 41 penetrating through the fixing plate 1, and the first connecting shaft 22 is inserted into the installation hole 41 and is rotatably connected with the installation hole 41. The mounting table 4 and the fixing plate 1 may be integrally cast, and the mounting table 4 increases the thickness of the fixing plate 1 and increases the depth of the first connecting shaft 22 inserted into the mounting hole 41. After the first connecting shaft 22 is inserted into the mounting hole 41, a certain friction force exists between the first connecting shaft 22 and the inner wall of the mounting hole 41, so that the first connecting shaft 22 is prevented from being separated from the mounting hole 41, and the first connecting shaft 22 can be ensured to rotate.
The top of the second connecting shaft 23 penetrates through the positioning pulley 3, and a clamping groove 33 is formed in the top of the second connecting shaft 23. Preferably, the card slot 33 is a straight card slot or a cross card slot. Since the first connecting shaft 22 and the second connecting shaft 23 are not coaxial, the second connecting shaft 23 and the positioning pulley 3 actually rotate around the first connecting shaft 22 during the rotation of the eccentric mounting shaft 2, and therefore the position of the positioning pulley 3 can be adjusted by rotating the eccentric mounting shaft 2. The side surface of the main shaft 21 is provided with a hole 5. When the eccentric mounting shaft 2 needs to be rotated, the eccentric mounting shaft can be inserted into the clamping groove 33 by a screwdriver for rotation adjustment, or can be inserted into the hole 5 by a rod-shaped prying piece for adjustment, so that the operation is simple and convenient.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
