1 fixation is also convenient for processing.
As shown in figure 4, being provided with limit in the first end of the first clamping portion 121 and the first end of the second clamping portion 122
The position limiting structure 123 of structure 123, the position limiting structure 123 of the first clamping portion 121 and the second clamping portion 122 is formed by the first mold,
Pockets 111 are formed by the second mold, and the depanning of the second mold and the first mold is contrary.Above-mentioned depanning mode more adduction
Reason, so that the processing of position limiting structure 123 and pockets 111 is more convenient.
As shown in Fig. 2, the thickness of the axis direction along idler wheel 1 of the first clamping portion 121 be less than wheel shaft 2 along idler wheel 1
The length of axis direction, the thickness of the axis direction along idler wheel 1 of the second clamping portion 122 are less than the axis along idler wheel 1 of wheel shaft 2
The length in direction.Above structure makes the outer end (one end of wheel shaft 2 far from wheel body 3) of wheel shaft 2 can be 111 by pockets
Support.
As shown in figure 4, side wall opposite between the first clamping portion 121 and the second clamping portion 122 is parallel to each other.Above structure
Convenient for depanning.
For the ease of the assembly of the wheel shaft 2 of idler wheel 1, as shown in figure 4, in the present embodiment, the corresponding of support portion 11 accommodates
At least one of first end of one end of groove 111, the first end of the first clamping portion 121 and the second clamping portion 122 is upper to be arranged
There is guiding expansion mouth 112.
In order to improve structural strength and facilitate processing, support portion 11 and clamping portion 12 are an integral molding structure.Certainly, two
It sticks together after can also being processed respectively between person or is linked together by fastener.
Present invention also provides a kind of air conditioners, include rolling according to the embodiment (not shown) of the air conditioner of the application
Quick release structure, roller fixing structure are above-mentioned roller fixing structure.Due to above-mentioned roller fixing structure, energy
The unfailing performance for enough improving moving component, improves the quality of product.
