Description

[Detailed description of the invention] The present invention relates to an air port position regulating device for an air chamber used in air brakes, etc., and in particular, when assembling the air chamber lid member to the air chamber body after replacing the air chamber diaphragm, the position of the air port is always kept constant. The present invention relates to an airport position regulating device that regulates the position of an airport.

Conventionally, as shown in FIG. 1, when an air chamber 1 is disassembled to replace a diaphragm (not shown) and assembled, the air port 3 of the air chamber 1 is aligned with respect to the position of an air pipe 2 fixed to a vehicle (not shown). The position A of is shifted to B or C, and the air pipe 2 cannot be connected to the air port 3, and it is necessary to repeat the assembly many times.
Therefore, assembling by visual inspection was extremely troublesome. Moreover, in order to prevent this, there is a drawback that a special tool is required to regulate the mounting angle of the air port 3.

The present invention was devised to eliminate the drawbacks of the prior art described above, and its purpose is to provide a thin resin plate that is extremely lightweight and has a simple structure and is placed between the air chamber body and the lid member. By doing so, when disassembling and reassembling the air chamber, the lid member can be installed so that the air port is always in the correct position facing the air pipe, and this also allows special The purpose is to eliminate the need for tools and facilitate maintenance of the air chamber.

In short, the present invention provides an air chamber in which a lid member provided with an air port boss is removably disposed on an air chamber main body, and the air port is inserted between the air chamber main body and the lid member, and one end on the side of the lid member is provided with the air port. The boss is provided with a removable hole, and one end of the air chamber body side is provided with a thin resin plate that can be removably attached to the air chamber body using at least two resin fasteners. .

The present invention will be explained below based on embodiments shown in the drawings. The air chamber 11 is an air chamber main body 12
A lid member 14 provided with an airport boss 13 against the lid member 14
is disposed removably between the air chamber main body 12 and the lid member 14, and a hole 15b is provided at one end 15a on the lid member side to be removably attached to the air port boss 13. One end 15c is provided with a thin resin plate 15 that can be detachably attached to the air chamber body 12 with at least two resin fasteners 16.

As shown in FIGS. 3 and 4, the fastener 16 has a round hole 17a at its entrance and a spherical recess 17 inside.
b, the female member 17 having the cylindrical portion 17c press-fitted into the air chamber body 12;
A male member 1 consisting of a rod-shaped part 18a, a spherical part 18b, and a circular head 18c, which are inserted into and held in a round hole 17a and a spherical recess 17b of No. 7.
6 are constructed as a pair, and the thin resin plate 15 is detachably held.

Note that a clamp band 19 is attached to the resin thin plate 15.
A bent portion 15d is formed so as to straddle the portion, and the clamp band 19 is adapted to be tightened with a bolt 20.

The present invention is constructed as described above, and its operation will be explained below. In the assembled state of the air chamber 11, the air chamber 11 is as shown in FIG.

To disassemble the air chamber 11, use bolts 20
Loosen the clamp band 19, remove the male member 18 of the fastener 16 from the female member 17, and remove the lid member 14 from the air chamber body 12.
In this case, the resin thin plate 15 may be removed from the lid member 14.

Further, the lid member 14 can be removed from the air chamber body 12 by simply bending one end 15a of the fastener 16 and removing it from the air port boss 13 while the fastener 16 is fixed.

When reassembling the diaphragm after replacing it, first fit one end 15a of the thin resin plate 15 into the air port boss 13, then rotate the lid member 14 appropriately to adjust the position of the male member 18 of the fastener 16 to the air chamber body 12. Female member 1 press-fitted into
If these are combined according to the position of 7, the position of the air port boss 13 will be the same as that of the air pipe 2 (first
(Figure) is set in the correct position facing the camera.

In addition, if the thin resin plate 15 is disassembled while being fixed to the air chamber body 12, the position of the air port boss 13 is at the hole 1 of one end 15a of the thin resin plate 15.
What is necessary is just to rotate and align the lid member 14 so that it may correspond to 5b.

In either case, the assembly is completed by tightening the clip band 19 with the bolt 20. At this time, the position of the air port boss 13 must be
Since the position coincides with the position of the air pipe 2, it becomes extremely easy to connect the air pipe 2.

Since the present invention is constructed and operates as described above, a thin resin plate that is extremely lightweight and has a simple construction is placed across the air chamber body and the lid member, so that it can be easily disassembled and reassembled. ,
The lid member can be attached so that the air port is always in the correct position facing the air pipe, no special tools are required, and the air chamber can be easily maintained. In addition, since the air chamber body and the lid member are aligned using a thin resin plate, a hinge mechanism is not required because the thin plate is flexible, and the weight is extremely light compared to press parts made of sheet metal. There is. Furthermore, since the thin resin plate is fixed with resin fasteners, the fixation is reliable and the number of man-hours is significantly less than that required for fixing sheet metal by welding.
