Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating body mounting structure in an air conditioning air passage.

[0002]

2. Description of the Related Art A conventional rotating body mounting structure in an air conditioning air passage will be described below.

In FIGS. 5 and 6, shaft holes 2 and 3 are provided in opposite walls of a case body 1 which is an air-conditioning air passage, and a valve (rotating body) 5 rotates in the shaft holes. It is provided freely.

That is, a groove 6 is formed on the outer periphery of the valve 5, and a sealing material (not shown) is fitted in the groove 6. Shafts 7 and 8 are formed on both sides of the valve 5, and a protruding rib 9 is formed adjacent to one shaft 7 so as to project from the end of the valve 5. The dimension A from the end surface of the rib 9 to one side edge of the valve 5 is set to be substantially equal to the inner dimension A of the case body 1.

When the valve 5 is attached to the case body 1,
The shafts 7 and 8 of the valve 5 spread the wall of the case body 1 to forcefully press the shafts 7 and 8 into the shaft holes 2 and 3.

As for this type of rotary member mounting structure, there is one disclosed in Japanese Utility Model Laid-Open No. 18249/1992.

[0007]

However, in the above-mentioned conventional structure, it takes time to mount the valve 5 on the case body 1 and a certain amount of force is applied, so that there is a drawback that the workability is poor, and the valve 5 is used. There was a problem that the shafts 7 and 8 were crushed during press fitting and the operating torque of the valve 5 varied.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide an air-conditioning air which has a short working time, has good workability, does not have a shaft collapse, and has no variation in operating torque. It is to provide a rotating body mounting structure in a passage.

[0009]

In order to achieve the above object, a rotating body mounting structure in an air conditioning air passage of the present invention is rotatably supported by shaft holes provided in opposite walls of the air conditioning air passage. A rotating body mounting structure in an air-conditioning air passage, the rotating body mounting structure including a rotating body, and a protruding portion protruding from an end portion of the rotating body adjacent to one shaft of the rotating body. Is provided adjacent to the shaft hole for inserting the projecting portion in an inclined manner, and the insertion hole is located outside the operating angle range of the rotating body.

[0010]

With the above construction, when the rotary body is mounted in the air-conditioning air passage, the projecting portion is obliquely inserted into the insertion hole, so that no force is required and the work is easy and the working time can be shortened. . Further, there is no shaft crushing and there is no variation in operating torque.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The same parts as those shown in the conventional example are designated by the same reference numerals.

Axial holes 2 and 3 are provided in opposing walls of the case body 1 which is an air conditioning air passage, and an inclined notch (insertion hole) 4 is provided adjacent to one axial hole 3. ing. The inclination angle of the notch 4 is set so as to fall outside the range of the operating angle B of the valve 5, and within the range of the operating angle B of the valve, the rib 9 of the valve 5 to be described later is formed in the notch 4. It is provided at a position where it does not enter.

A groove 6 is formed on the outer periphery of the valve 5, which is a rotating body, and a seal member (not shown) is fitted in the groove 6. Shafts 7 and 8 are formed on both sides of the valve 5, and ribs (protruding portions) 9 that project from the end of the valve 5 are formed adjacent to one shaft 7. Then, when the shaft 7 is inserted into the shaft hole 3 of the case body 1 while being inclined, the rib 9 is set to be inserted into the notch 4 of the case body 1 while being inclined.

A process of mounting the valve 5 on the case body 1 constructed as above will be described with reference to FIGS. 2 to 4.

One shaft 7 of the valve 5 is obliquely inserted into the case body 1, and one shaft 7 of the valve 5 and the rib 9 are cut into the shaft hole 3 and the notch 4 of the case body 1. By simultaneously inserting the valve 5 obliquely from above along the notch 4, the valve 5 is unevenly distributed toward the shaft hole 3 side. (FIGS. 1 and 2) Next, after pushing the other shaft 8 of the valve 5 in the direction of the other shaft hole 2 of the case body 1 to make the shaft 8 face the shaft hole 2,
The valve 5 is moved in parallel to the shaft hole 2 side, the shaft 8 is inserted into the shaft hole 2, and the rib 9 is pulled out from the notch 4. (FIG. 3) Finally, the valve 5 is rotated within the range of the operating angle B to move the rib 9
Moves to a position not facing the notch 4.

As described above, one of the shaft holes 2 and 3 provided in the opposite walls of the case body 1 and the notch 4 provided adjacent to the shaft hole 3 is provided with the valve 5. A step of causing the valve 5 to be unevenly distributed to the one shaft hole side by simultaneously inserting the one shaft 7 and the rib 9 formed so as to project adjacent to the one shaft from an oblique direction at the same time outside the working operating angle range of the valve 5. After the other shaft 8 of the valve 5 is opposed to the other shaft hole 2 of the shaft holes 2 and 3 of the walls of the case body 1 facing each other, the valve 5 is parallel to the other shaft hole side. Moving and inserting the other shaft 8 into the other shaft hole 2 and pulling out the rib 9 from the notch 4, and rotating the valve 5 within the operating angle range of the valve 5 so that the rib 9 is notched. 4 and the step of moving to a position not facing When attached to the over scan body 1, the ribs 9 in the notch 4 since being inserted obliquely, forces work can be workability is improved to shorten the easy working time keeps.

Further, by providing the inclined notch 4 adjacent to the shaft hole 3 facing the one shaft 7, the rib 9 is obliquely inserted into the notch 4 when the valve 5 is mounted on the case body 1. As a result, the shafts 7 and 8 do not collapse and the operating torque does not vary.

Furthermore, the above-described method and configuration can be used for mounting a louver for air conditioning.

[0019]

As described above, according to the present invention, the rotating body is rotatably supported by the shaft holes provided in the opposite walls of the air-conditioning air passage, and is adjacent to one shaft of the rotating body. Is a rotating body mounting structure in an air-conditioning air passage in which a protruding portion protruding from an end of the rotating body is formed, and an insertion hole for obliquely inserting the protruding portion adjacent to a shaft hole facing the one shaft. Since the insertion hole is provided outside the working angle range of the rotating body, when the rotating body is installed in the air conditioning air passage, the projecting portion is obliquely inserted into the insertion hole, which facilitates the work. The working time can be shortened and there is no crushing of the shaft, and there is no variation in operating torque.
