This operation box activates the fire extinguishing system by opening the door and pressing the internal start switch, but at this time, opening the door of the operation box will issue an alarm in the fire extinguishing section,
Further, when the start switch is pressed, the fire extinguishing equipment is started. [0003] In recent years, accidents in which manual starting devices of these gas fire extinguishing systems are erroneously operated due to human error and fire extinguishing agents are unintentionally discharged tend to increase. is there. When the door is opened, an evacuation alarm is issued in the fire extinguishing compartment.However, at the position of the operating box, there is no announcement as to how the fire extinguishing compartment will be in particular. It is highly likely that an erroneous operation of the manual starting device has been induced. The present invention has been made in view of the above-mentioned problems of the operation box of the conventional gas fire extinguishing system, and has a large locking member for the door to improve the holding force of the closed state of the door and to open the door by deformation of the door. Provided is an operation box for gas fire extinguishing equipment that can prevent a malfunction of a detection switch and further provide a time interval for opening a door even if the user is upset, thereby reducing the possibility of accidentally opening the door. The purpose is to: [0005] In order to achieve the above object, an operation box for a gas fire extinguishing system according to the present invention comprises a door for a gas fire extinguishing system incorporating a manual starting device for a fire extinguishing system. Is hinged to the operation box main body so as to be openable and closable, and a locking member for holding the door in a closed state is disposed substantially at the center of the opening and closing side of the door, and a door opening for detecting the opening of the door is provided. The detection switch is disposed close to the locking member, and the door opening puller is formed so as to be deviated above or below the locking member. In the operation box of this gas fire extinguishing system, a locking member for holding the door in a closed state is disposed substantially at the center of the open / close side of the door, so that the locking member is enlarged to close the door. By improving the holding force of the door and by arranging a door open detection switch that detects the opening of the door close to the locking member,
Prevents the door opening detection switch from malfunctioning due to the deformation of the door.Furthermore, by forming a door opening handle above or below the locking member, the handle is displaced from the center of the open / close side of the door. With such a configuration, even if the user is upset, the door can be opened in a timely manner, and the possibility of opening the door by mistake can be reduced. Furthermore, by forming the handle part deviated from the center of the open / close side of the door, the outer shape of the operation box can be made compact both in vertical and horizontal thickness, and a large space can be secured in depth and width. In addition, since the door is prying open, the opening operation force can be reduced while the door closing holding force against normal vibrations etc. is increased, and the tamper-proof seal is attached to the operation box body and the door. Since a sufficient space can be secured in the center of the opening / closing side portion of the door, the visibility of the seal can be improved and the appearance of the operation box at the time of final installation can be improved. An embodiment of an operation box for a gas fire extinguishing system according to the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show an embodiment of an operation box of a gas fire extinguishing system according to the present invention. For example, as shown in FIG. 2, the operation box of this gas fire extinguishing system
Used for The carbon dioxide fire extinguishing system 1 includes a plurality of fire extinguisher storage containers 11 for storing carbon dioxide, a plurality of jet heads 13 arranged in the fire extinguishing section A from the fire extinguisher storage containers 11 via the flow paths 12, A selection valve 14 provided in the middle of the passage 12, a starting gas container 15 for operating the selection valve 14, and a container valve solenoid 15 of the starting gas container 15;
a that operates the control panel a. Control panel 16
Is electrically connected to a fire detector 2 serving as a detector of the automatic starter and an operation box 3 having a starter switch serving as a manual starter. On the other hand, the operation box 3 activates the fire extinguishing equipment by opening the door 31 and pressing an internal start switch 32. When the door 31 of the operation box 3 is opened, the speaker 17 which issues an alarm is extinguished. It is arranged in the section A. As shown in FIG. 1, the operation box 3 hinges the side 31a of the door 31 to the operation box main body 33 so as to be openable and closable.
A magnet catch 34 for holding the door 31 in a closed state is provided substantially at the center of the opening / closing side portion 31b.
A micro switch 35 for detecting the opening of the door is arranged close to the magnet catch 34, and a puller groove 36 for opening the door is formed so as to be deviated below the magnet catch 34. The magnet catch 34 has a magnet main body 34a fixed to the operation box main body 33, and a suction iron plate (not shown) fixed to the door 31. Also,
The micro switch 35 is fixed to the operation box main body 33, and the actuator 35a urged to protrude toward the door 31 is retracted by abutting on the closed door 31 via the pressing plate 35b. It has become. When the door 31 is opened, the actuator 35a is released from contact with the door 31, moves in the biasing direction and closes the contact,
This is a switch that sounds an alarm from the speaker 17 in the fire extinguishing section A. The puller groove 36 is provided on the opening / closing side 3 of the door 31.
It is also possible to form on top of 1b. Thus, the operation box of the gas fire extinguishing system according to the present embodiment has the magnet catch 34 provided at the substantially center of the open / close side portion 31b of the door 31 for holding the door 31 in the closed state. The size of the micro switch 35 for detecting the opening of the door 31 is increased by increasing the size of the
, The movement of the actuator 35a due to the deformation of the door 31 can be suppressed, and the malfunction of the microswitch 35 can be prevented. Then, by forming the handle groove 36 for opening the door so as to be deviated above or below the magnet catch 34, the drawer groove 36 was prevented from being positioned at a central easy-to-see place, so that the user was upset. Even in this case, the possibility of opening the door 31 by mistake can be reduced by providing a time interval for opening the door 31. Further, as described above, the puller groove 36 is connected to the door 3.
By arranging the opening / closing side portion 31b so as to be shifted from the center, the following merits arise. There is no wasted space, the outer shape of the operation box 3 in both vertical and horizontal thicknesses can be made compact, and a large space can be secured in depth and width. Since the door 31 is opened in a prying manner, the opening operation force can be reduced while the door closing holding force against vibrations and the like in a normal state is increased. To prevent mischief, a seal "strictly prohibited except for fire" must be provided so as to straddle between the operation box main body 33 and the door 31, but sufficient space is secured in the center of the open / close side 31b of the door 31. Therefore, the visibility of the seal can be improved and the appearance of the operation box 3 at the time of final installation can be improved. According to the operation box of the gas fire extinguishing system of the present invention, the locking member for holding the door in a closed state is provided at substantially the center of the opening / closing side of the door, whereby the door is closed. Enlarging the stop member to improve the holding force of the door closed state, and arranging a door open detection switch that detects the opening of the door close to the locking member allows the door open detection switch to be By preventing malfunction, and furthermore, by forming a pulling portion for opening the door above or below the locking member, the pulling portion is formed so as to be deviated from the center of the opening and closing side portion of the door. Even in the case of getting upset, it is possible to reduce the possibility of opening the door by giving a pause to the way of opening the door. Furthermore, by forming the handle part deviated from the center of the open / close side of the door, the outer shape of the operation box can be made compact both in vertical and horizontal thickness, and a large space can be secured in depth and width. In addition, since the door is prying open, the opening operation force can be reduced while the door closing holding force against normal vibrations etc. is increased, and the tamper-proof seal is attached to the operation box body and the door. Since a sufficient space can be secured in the center of the opening / closing side portion of the door, the visibility of the seal can be improved and the appearance of the operation box at the time of final installation can be improved.
