Abstract

PURPOSE:To maintain a perfect airtightness with a simple operation, by applying a clamping mechanism. CONSTITUTION:A flap 13 is pressed to return to a proper position against a spring force. A rotational movement of the flop 13 is stopped at this position by a stopper 133. A gasket 22 of an air-filter element 2 of an article to be attached is inserted into a channel 11 from the open side-end 111 of the channel 11 while inserting a guide 21 along a notched groove 110 of the channel 11. Then the flap 13 is released by releasing the stopper 133. An acting end 132 of the flap 13 presses the gasket 22 to the inner wall of the channel 11 by the spring force of an elastic material 12. The gasket 22 is attached to an attaching device 1 in such a manner. The gasket 22 is separated from the attaching device 1 by drawing out the gasket 22 from the open side-end 111 of the channel 11.

Description

[Detailed description of the invention] The present invention relates to a mounting device using a clamp mechanism.

Conventional Mounting Device 1 For example, an air filter mounting device disclosed in Japanese Patent Application Laid-open No. 51-138960 includes a rod-shaped air pick 1 formed of a hollow tube and covered with a packing material to be mounted. It is designed to fit a letter frame. The mounting device has this structure.

Not only is the airtightness not perfect, but the seals tend to disappear quickly, resulting in high costs.

SUMMARY OF THE INVENTION An object of the present invention is to provide an economical mounting device that is simple in structure and easy to operate, and can maintain complete airtightness.

The present invention will be described in detail below based on embodiments and with reference to the drawings.

As shown in FIG. 1, there are two mounting devices 1 according to the present invention.

It has a clamping mechanism, and has a channel 11 with an open side surface 111, an elastic member 12 such as a spring mounted inside the Teyanne/L/11, and a slump 13. The slump 13 has one end 131 fixed to the pivot and the other end 132 responsive to the spring force of the elastic member 12. This slump 13
The pivot movement can be stopped at any position by a stopper, for example, a commonly used stopper 133, which has a structure in which one screw is screwed into the other, if a double screw structure is provided at the pivot center 130.

The gasket 22 attached to the object 1 to be attached, for example, as shown in FIG. It can be taken like that. First, slump 1
Push 3 back to the appropriate position against the spring force. The pivot movement of the slap 13 is stopped by a stopper 133 at this position.

Next, in step A, the gasket 22 of the air filter element 2 to be installed is inserted from the entrance side end 111 of the channel 11 into Teyanne/L'll while aligning the guide 21 with the channel notch ##tio. The stopper 133 is released to release the slump 13. Slump 13 is elastic material 1
Due to the spring force of 2, its responsive end 132 presses the gasket 22 against the inner wall of Tejanne/L/11. Gasket 22
In this way, the mounting device IK can be removed. Push the slump 13 back again against the spring force, fix the slap 13 at that position by operating the stopper 133,
By pulling out the gasket 22 from the channel opening side 111, the gasket 22 can be removed from the mounting device.

An example of the application of the device 1 of the present invention is shown in FIG. 3 (a3. (t) and (a3). The engaging members 4 are attached in a staggered manner to each of the pair of mounting devices 1.1 through a sealing material 41.41 in a removable manner and airtightly engage the pair of mounting devices 1.1. 1.1 is engaged with each engaging portion 4 so that the side surface thereof forms a V-shape.

As a result, when the air filter elements 2 are sequentially attached to each mounting device 1, the air filter elements 2, 2.
... are attached in a zigzag manner within the housing 3. The p-permeable surface 20 of the air filter element 2 faces in the direction of the airflow flowing from the front surface 30 to the rear surface 33 of the housing 3. The pre-filter element is attached to the []rJ side of the filter elements 2, 2, .

These filter elements 2, 2, . . . and 5.

5... is inserted into the housing 3 on the housing side surface 34
is provided with a door 35. When this door 35 is closed, the filter elements that are in Igh contact with each other and the filter elements and the inner surface of the housing are exposed to air by the gasket 23 installed in the valley filter element 2. Fit. As a result, each air filter element 2 is connected to each other in an air-tight manner by the mounting device IK of the present invention at the intersection thereof, and on the side thereof, the air filter elements 2 are in air-tight pressure contact with adjacent elements 2 in parallel and with the inner surface of the housing. However, it is possible to obtain an air filter unit that maintains complete airtightness as a whole and has no near leaks.

Since the device of the present invention has such a configuration and function, it can produce excellent effects corresponding to the above-mentioned objects.
