Description

Linkage device for EMC darkroom pneumatic lifting slope

Technical Field

The utility model belongs to the technical field of the EMC darkroom, concretely relates to a aggregate unit that is used for pneumatic lift slope of EMC darkroom.

Background

The threshold of the EMC darkroom shielding gate is higher than the ground, so that a raised floor needs to be paved in the darkroom, the ground in the darkroom is horizontal to the threshold, and the outside of the darkroom is convenient for workers to get in and out, so that a liftable slope is needed. Due to comprehensive consideration on safety and economy, an air cylinder is selected as a power source, the lifting of a pneumatic lifting slope needs to be independently controlled, a shielding gate A is rotatably connected to a door frame B when an EMC dark room opens and closes a door, the shielding gate A is opened to a certain angle, then a control box is operated, the pneumatic slope is lifted for use, potential safety hazards exist in the middle of the pneumatic slope, and if the shielding gate A is not opened at the enough angle, the shielding gate A can be extruded when the slope is lifted, and the shielding gate A is damaged.

SUMMERY OF THE UTILITY MODEL

To the problem that the above-mentioned background art provided, the utility model aims at: aims to provide a linkage device for an EMC darkroom pneumatic lifting slope.

In order to realize the technical purpose, the utility model discloses a technical scheme as follows: the utility model provides a aggregate unit for pneumatic lift slope of EMC darkroom, includes the fixed plate, T type slide rail is installed to the fixed plate downside, install the slider on the T type slide rail, the locating hole has been seted up on the slider, the slider front side is rotated and is installed the pull rod, the hole of stepping down has been seted up on the fixed plate, pneumatic travel switch is installed to the hole upside of stepping down, the cylinder is installed in hole left side of stepping down, the cylinder output passes T type slide rail and pegs graft in the locating hole, the limiting plate is still installed to the fixed plate both sides.

Further inject, slider and T type slide rail tight fit slip, such design can guarantee can prevent that the shield door from rocking at will when the switch door.

Further inject, still install the voice broadcast device on the fixed plate, such design, voice prompt notices safety when the switch door, improves the security when moving.

Further inject, the cylinder still is connected with pneumatic button, and such design, the button is pressed down, and the cylinder withdraws, and the shielding gate is closed safely.

Adopt the utility model discloses a beneficial effect:

the utility model links the lifting of the pneumatic lifting slope and the switch of the shielding gate, the slope automatically rises after the shielding gate is opened to a certain angle, and meanwhile, the shielding gate can be locked by the linkage device, so that the gate is prevented from rotating towards the closing direction, the number of components is small, the assembly is simple, and the scheme is simple and safe to use;

Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

As shown in fig. 2-4, the utility model discloses a aggregate unit for pneumatic lift slope of EMC darkroom, including fixed plate 1, T type slide rail 2 is installed to 1 downside of fixed plate, installs slider 3 on the T type slide rail 2, has seted up locating hole 31 on the

slider

3, and 3 front sides of slider rotate and install pull rod 4, have seted up the hole of stepping down 11 on the fixed plate 1, and pneumatic travel switch 12 is installed to the hole of stepping down 11 upside, and the cylinder 5 is installed in hole 11 left side of stepping down, and the cylinder 5 output passes T type slide rail 2 and pegs graft in locating hole 31, and limiting plate 6 is still installed to 1 both sides of fixed plate.

In this embodiment, when a linkage for an EMC darkroom pneumatic lifting slope is used, as shown in fig. 1, the linkage device is installed on a door frame B through a fixing plate 1, the other end of a pull rod 4 is rotatably installed on a shielded gate a, when the shielded gate a is opened in use, one end of the pull rod 4 moves along with the shielded gate a, the other end drives a sliding block 3 to slide on a T-shaped sliding rail 2, when the shielding gate A is opened to a certain angle, the sliding block 3 can sense the pneumatic travel switch 12, the pneumatic travel switch 12 is closed, the air cylinder 4 in the linkage device and the air cylinder of the pneumatic lifting slope work simultaneously, when the shielding gate A is locked, when the shielding gate A is required to be closed when the slope rises, the pneumatic button is arranged beside the gate handle, the pneumatic button is pressed down, the cylinder in the linkage device and the cylinder of the pneumatic lifting slope retract at the same time, and the shielding gate A is closed safely.

Preferred

slider

3 and 2 tight fit of T type slide rail slide, such design can guarantee can prevent that the shield door from rocking at will when the switch door, also can consider other structures according to actual conditions in fact and prevent that the shield door from rocking.

Still install voice broadcast device on preferred fixed plate 1, such design, voice prompt notices safety when the switch door, improves the security when moving.
