Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an outdoor cubicle pedestal, and more particularly to an improvement of an outdoor cubicle pedestal door installed in a high dust atmosphere such as in a tunnel for automobiles or in a steel mill.

[0002]

[Prior art]

 Conventionally, in an outdoor cubicle stand installed in a high-dust atmosphere such as in a tunnel for automobiles or in a steel mill, in order to protect the analyzers, electronic components, fans, etc. stored inside, from dust, the door is dust-proof. The packing for was attached. For example, as shown in FIG. 6, the packing 1 is formed in a ring shape having a flat cross-sectional shape, and is attached to the inner surface of the peripheral portion of the rectangular door 2, and when the door is closed, the flange of the gantry body 3 is closed. It was configured so as to be in close contact with the opening peripheral portion 4 formed in the shape of a dip and to keep the inside of the gantry body 3 airtight.

[0003]

[Problems to be solved by the device]

 However, in the outdoor cubicle pedestal 5 as described above, when a large vehicle passes by it or is hit by a strong wind such as a typhoon, the vibration and wind pressure cause the door 2 to move inward and outward as shown by the phantom line. There was a case where a vibration was generated so as to bend and a gap was created between the gantry body 3 and the door 2, and dust, raindrops, or the like entered from the outside. This is because when the door 2 bends inward, the packing 1 is compressed to maintain tight dustproofness and airtightness, but when the door 2 flexes outward due to the reaction, the elastic force of the packing 1 This is because there is a gap between the packing 1 and the opening peripheral edge portion 4 of the gantry body 3 because the door 2 is repelled outwards. If such vibrations are repeated, a kind of breathing action is generated, and external dust, raindrops, etc. are sucked into the inside of the gantry main body 3, so that the performance of the analyzer is deteriorated and the parts are damaged. It deteriorates or shortens its life.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide an outdoor cabicle stand that is particularly dustproof and airtight.

[0005]

[Means for Solving the Problems]

 The present invention has means for solving the above-mentioned problems as follows. That is, in a door that is openably and closably provided on the front surface of a cubicle frame placed in a high dust atmosphere, one end side of the door is pivotally attached to one side wall edge of the frame body by a hinge, and the door is An outer packing is provided between the inner surface of the peripheral edge of the door and the peripheral edge of the opening of the gantry body when closed, and is formed inside the peripheral edge of the opening when the door is closed. It is characterized in that an inner packing which is in close contact with the surface in the door opening / closing direction is attached to the inner surface of the door rather than the inner surface of the peripheral portion thereof.

[0006]

[Action]

 Even if dust or raindrops may enter the inside of the door when it is exposed to vibration or wind pressure, the inside of the door may be closer to the surface formed in the opening / closing direction of the door. The inner packing that keeps dust and airtightness prevents dust and raindrops from entering the pedestal body. In other words, even if the door vibrates so as to bend inward and outward, the inner packing maintains a close contact state only by closely sliding on the surface in the opening / closing direction of the door.

[0007]

【Example】

 Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 3 is a cross-sectional view of a tunnel 8 for an automobile in which an outdoor cubicle mount 5 is arranged. The outdoor cubicle mount 5 is a recess formed by excavating a part of a side wall 10 facing a road 9. The door 2 installed on the front side of the gantry body 3 (see the figure) faces the roadway 9, and the sample gas sampling port 11 is separately provided below the door 2 toward the roadway 9. The atmosphere in the tunnel 8 can be introduced into an analyzer (not shown) in the gantry body 3 to measure various components. A plurality of outdoor cubicle mounts 5 are arranged in the tunnel 8 at appropriate intervals, and detection signals from each of the outdoor cubicle mounts 5 are sent to a computer (not shown) to measure various components. It can be obtained as a numerical value.

As shown in FIGS. 1 and 2, the outdoor cubicle mount 5 has a front surface of a mount body 3 covered by an openable / closable door 2 pivotally supported at one end by a hinge 6, and an operation of a handle 7. The door 2 is locked to the gantry body 3 to keep dustproof and airtight, and the analyzer, various parts, fans, etc. installed inside can be protected.

A structure for obtaining the dustproofness and airtightness is shown in FIG. 1, and an outer packing 13 formed into a ring shape with a flat cross section is attached to an inner surface of a peripheral edge portion of the door 2, When the door is closed, the outer packing 13 is in close contact with the flange-shaped opening peripheral portion 4 of the gantry body 3, and the surface of the door opening / closing (front-rear) direction formed continuously inside the opening peripheral portion 4 is formed. The tip of the ring-shaped inner packing 14 attached to the inner surface of the door inside the outer packing 13 is in close contact with the outer packing 15. With such a structure, when the door 2 vibrates inward and outward due to vibration or wind pressure, even if dust or raindrops penetrate the outer packing 13 and enter the inside, Since the inner packing 14 provided at the upper part of FIG. 1 sufficiently keeps dustproofness and airtightness, the dust and raindrops are prevented from entering the inside of the gantry body 3. That is, when the door 2 bends inward and outward, the inner packing 14 only moves in parallel with respect to the surface 15 of the gantry body 3 formed in the same direction, so that the close contact is maintained. This is because the dustproof and airtightness is sufficiently maintained even by vibration.

More specifically, the outer packing 13 described above may be attached to the inner surface of the peripheral portion of the door 2 with an adhesive or the like, or may be attached to the opening peripheral portion 4 of the gantry body 3. . On the other hand, the inner packing 14 is formed with a contact portion 14a having an outer peripheral portion having a tongue-shaped cross section, a mounting groove 14b is formed in the inner peripheral portion, and the mounting groove 14b is welded to the door 2. The mounting member 16 is detachably fitted to the flange portion of the mounting member 16, and the contact portion 14a thereof is brought into close contact with the surface 15 in the door opening / closing direction when the door is closed.

The lock mechanism of the door 2 is configured such that a lot rod 7a that vertically expands and contracts in conjunction with a handle 7 (see FIG. 2) is removably engaged with upper and lower engaging portions of the gantry body 3. By the way, when locked, the upper and lower parts of the door 2 are firmly locked to the gantry body 3. In the locked state, as shown in FIG. Tight dustproof and airtightness is ensured by being compressed in the opening peripheral edge portion 4 of the inner peripheral surface of the inner peripheral surface of the inner peripheral surface of the inner peripheral surface of the inner peripheral surface. Keeps dustproof and airtight.

On the other hand, in the lower part of the door 2, a ventilation port 20 that is a combination of a filter, packing, and a louver plate is opened, and the gantry body 3 is provided with a dustproof and ventilation function. A stay (not shown) that is slidably linked to the upper edge of the gantry body 3 is pivotally attached to the upper pivot side of the door 2 so that the door 2 can be smoothly opened and closed between the open limits. ing.

FIG. 4 shows a different embodiment, in which the contact portion 14a of the inner packing 14 is formed in a round shape, and it is possible to achieve the same effect as the previous embodiment.

FIG. 5 shows another embodiment, in which the inner packing 14 is formed in a tube shape and is attached to a mounting frame 18 made of synthetic resin.

[0015]

[Effect of device]

 As described above, according to the present invention, when the door is closed, the outer packing closely provided between the inner surface of the peripheral edge of the door and the peripheral edge of the opening of the gantry body is provided, and the door is closed. At the same time, the inner packing, which is formed on the inner side of the opening peripheral edge and is in close contact with the surface in the door opening / closing direction, is attached to the inner surface inside the peripheral edge of the door, ensuring double dustproofness and airtightness. Even if the door vibrates so as to bend inward or outward due to vibration or wind pressure, the inner packing moves closely to the surface in the door opening / closing direction formed inside the opening peripheral edge of the gantry body. Only with this, sufficient dustproofness and airtightness can be maintained, and it is possible to prevent dust and raindrops from entering the inside.
