Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
A kind of self-fastening roll wheel assembly as shown in Figure 1, including positioning pin 1, rolling sleeve 2 and attachment base 3.It is right below
The structure of all parts is described:
One end of positioning pin 1 has the second caulking part 11 with the first caulking part 10, the other end, wherein the first caulking part 10
For connecting attachment base 3, the second caulking part 11 is used for connection plate 5.The outer diameter of first caulking part 10 of positioning pin 1 is less than it
The outer diameter of second caulking part 11.
Rolling sleeve 2 has cylinder circle 20, set on the annular protrusion 21 of 20 inner wall of cylinder circle.
One end of attachment base 3 offers the first riveted holes 30, the other end has limiting section 31, wherein the first riveted holes 30 are used
In connection positioning pin 1, limiting section 31 rolls sleeve 2 for limiting.
When self-fastening roll wheel assembly is assembled, sleeve 2 will be rolled and be set in outside positioning pin 1, then by positioning pin 1
First caulking part 10 is inserted into the first riveted holes 30 of attachment base 3, using riveting tool by the first caulking part 10 of positioning pin 1 with
First riveted holes 30 of attachment base 3 complete riveting, and sleeve is rolled after connection and is limited between positioning pin and attachment base and can be around
Positioning pin rotation, single component complete assembling.
After connection externally: the cylinder circle 20 for rolling sleeve 2 is located at the second caulking part 11 and attachment base 3 of positioning pin 1
