Description

[Detailed explanation of the idea] 〔Technical field〕 This invention relates to a fixture for parts.

[Prior art]

A simple structure that allows a roller whose end surface is supported pivotably on a mounting plate to be freely attached and detached for purposes such as replacing the belt attached to the roller is provided, for example, by providing a flange at the end of the shaft-like protrusion that supports the roller. It is known that the flange and the mounting plate are removably connected by bayonet connection or the like. In this conventional structure, the mounting tool consisting of the shaft-like protrusion and the flange is separated from the mounting plate and the roller, so the mounting tool may be lost when attaching or removing the roller, or it may be attached while the roller is rotating. There was a risk that the ingredients would become loose and fall off.

[Purpose of invention]

This invention provides a novel fitting to overcome the above-mentioned conventional drawbacks.

〔Example〕

In the figure, 1 is a roller on which a belt 2 is hung, 3 is a pair of mounting plates (only one is shown), and 4 is a mounting tool for rotatably mounting the roller 1 on the mounting plate 3.

The fixture 4 includes a base 41 and a shaft-shaped protrusion 4 that protrudes from one end of the base 41 in the axial direction of the roller 1.
2, a plurality (a pair) of elastic arms 43 protruding outward from the other end of the base 41 intersecting the axial direction; It is integrally formed of a synthetic resin material and has a pair of knob portions 44 protruding from the top.

The mounting plate 3 has a U-shape with both side edges bent toward the opposite side of the roller 1, and has a hole 31 in the center surface facing the recessed hole 1a provided in the end surface of the roller 1, and bent portions on both sides from the center surface. Each has a pair of latching holes 32 spanning the two sides.

The protrusion 42 of the mounting fixture 4 is inserted into the hole 31 of the mounting plate 3, and the arm 43 is inserted into the hook hole 32.
When the base 41 is pressed against the outer edge of the fastening hole 32 by its elasticity, the base 41 is pressed against the mounting plate 3 by the reaction force.
The projection 42 is pressed against the roller 1 and biased in a direction in which the projection 42 projects towards the roller 1. The roller 1 is attached rotatably with its recess 1a fitted onto the outer periphery of the projection 42.

As shown in FIG. 2, by holding the knob 44 and pulling the fixture 4 against the elasticity of the arm 43,
The roller 1 can be removed by retracting the protrusion 42 in the axial direction within the hole 31 and disengaging it from the recessed hole 1a of the roller 1. At this time, the arm portion 43 moves in the direction in which it comes out of the locking hole 32 while sliding on the outer edge, but if the arm portion 43 is sufficiently long or the arm portion 43
The arm 43 does not fall off from the mounting plate 3 because the raised portion 45 provided at the tip thereof contacts the outer edge of the locking hole 32 .

To install the roller 1, place the recessed hole 1a of the roller 1 and the hole 31 opposite to each other, release your hand from the knob 44, and adjust the elasticity of the arm 43 to the shaft 42.
What is necessary is to fit it into the recessed hole 1a of the roller 1.

It goes without saying that not only rotating parts such as rollers but also non-rotating parts can be removably mounted using the fixture 4.

Figure 3 shows the above mounting device used to install the filter belt of a cooling fan.
is a box that forms the exterior of the cooling fan, and has an air outlet 51 on the front.
A rear lid 54 having an air intake port 53 covered by an air filtration filter 52 is attached to the rear surface.

55 is a blower device, a cross-flow type fan 5
5a, and a fan guide 55b whose discharge side is once opened to the blow-off port 51. Reference numerals 56 and 57 are vertical direction changing louvers and left/right wind direction changing louvers that guide the air blowing direction.

In this embodiment, the belt 2 shown in FIG. is inserted into the water in the tank 58. roller 1,
1 is mounted horizontally between a pair of left and right mounting plates 3 (only one of which is shown) protruding from the inner surface of the rear lid 54, and is mounted using the mounting tool 4 as described above.

When the upper roller 1 is rotated by a small motor to drive the belt 2, the air sucked into the air blower 55 passes through the water contained in the belt 2, causing a temperature drop due to the heat of vaporization of the water. Accordingly, the air outlet 5
Cold air can be sent out from 1.

Due to long-term use, the belt 2 becomes dusty and needs to be cleaned or replaced. Remove the rear cover 54 to expose the belt 2, and attach the mounting tool 4 as described above.
By operating the roller 1 and removing it, the belt 2 can be taken out.

[Effect of idea]

As described above, this invention involves inserting the protrusion into the hole in the mounting plate, hooking the tip of the arm extending radially outward on the mounting plate, and using the elasticity of the arm to extend the protrusion. Since the device is moved in the direction of the component to be mated to and removed from the component to be attached, it is extremely easy to attach and remove the component to be attached, and since the mounting tool is always held on the mounting plate, it is possible to remove powder. There is no risk of loss, and even if the attached part rotates like a roller, it will not come loose, providing excellent practical effects.

Claims (1)

[Claims for Utility Model Registration] In the fixture 4 for attaching the component 1 to the mounting plate 3, the fixture 4 includes a base 41, a protrusion 42 protruding from the base 41, and a protrusion of the protrusion 42. A plurality of elastic arms 43 extending outward from the base 41 in a direction intersecting the direction are integrally formed of a synthetic resin material. A hole 31 is inserted into the hole 31 so as to be movable in the projecting direction, and each arm portion 43 is inserted into the hole 31 so as to be slidable against the elasticity of the hole 31.
The elastic force of the arm portion 43 causes the protrusion 42 to
a plurality of latching holes 32 for latching the tips of the respective arm portions 43 so as to be biased outward through the holes 31 of the mounting plate 3; The mounted part 1 is removably fitted onto the tip of the protrusion 42 protruding through the hole 31 of the mounting plate 3 by force, and the protrusion 42 is attached to the mounting plate against the elasticity of each arm 43. 3. A component mounting tool that allows a mounted component 1 to be removed by retracting the component 1 in a direction in which it is removed from the hole 31 of No. 3.
