Description

  The present invention relates to a structure of a connecting portion of a cabinet that houses various devices and can be connected by screwing adjacent main bodies.

  5 to 6 show a conventional cabinet connection structure. The cabinets 31 for storing communication devices and electrical devices may be connected and used depending on the amount of devices to be stored and restrictions on installation locations. At this time, the connection hole 33 was provided in the side surface of the main body 32 of the cabinet 31 for connection. The side face of the main body 32 is abutted, and a screw 34 is inserted through the connecting hole 33 on one side, and a nut 35 is provided in the other connecting hole 33, and the main body 32 is connected and fixed by tightening the screw 34. When the nut 35 is welded to the inside of the main body 32, it is not necessary to support the nut 35, and the nut 35 can be connected by inserting a screw 34 and tightening from one side.

  However, the cabinet 31 is not necessarily connected and used, or the cabinet installed at the end does not require the connection hole 33 and has a blind plate 36 attached to prevent the entry of foreign matter. .

  In the conventional cabinet 31, the front opening is covered with the door body, and the operation of tightening the screw while pressing the nut 35 reaches the inside of the main body 32 on both sides when the door body is opened. The work efficiency was poor because multiple workers were required. Also, due to recent computerization, devices are often densely mounted inside the main body 32, and when the main bodies 32 with such dense devices attached are connected, they are attached near the connection hole 33. The screw 34 and the nut 35 may not be attached unless the device is removed.

  When the nut 35 is welded and fixed to the main body 32, the diameter of the connecting hole 33 on the side where the screw 34 is inserted has a margin with respect to the diameter of the screw 34. Since the diameter 34 is securely tightened, when the blindfold plate 36 is attached to the connection hole 33 without being connected, the blindfold plate 36a that matches the diameter of the connection hole 33 and the blindfold plate 36b that matches the diameter of the nut 35 are provided. Had to be used. That is, it is necessary to produce the blindfold plate 36 that matches each diameter.

  Accordingly, the present invention has an object to provide a structure of a connecting portion that can be easily connected with a simple structure, and the structures face each other when the main body is placed in a connected state on both left and right sides of the cabinet. A connecting hole having the same diameter is formed at a position, and a fixing piece provided with a tap hole is attached to a position spaced from one of the connecting holes to the inside of the main body.

In the present invention, on the left and right sides of the cabinet, connecting holes having the same diameter are formed at positions facing each other when the main body is placed in a connected state, and tapped holes are formed at positions spaced from one of the connecting holes to the inside of the main body. Because the fixed piece provided is attached, it is not necessary to remove the door body that covers the front opening of the main body, because it is possible to insert and tighten the screw through the connecting hole on one side to connect adjacent main bodies. The efficiency of the connecting work can be greatly improved.

  In addition, when the main body is used as a single unit without being connected, or a connecting hole provided in the main body of the cabinet disposed at the end, a blindfold plate can be attached to prevent entry of foreign matter. Since the main body is provided with a connecting hole of the same diameter, a single type of blindfold plate can be shared, and both the conventional one that closes the connecting hole and the one that closes the connecting hole with the nut are blindfolded. It is possible to provide a blindfold at a low cost without producing a plate or taking time to stock parts.

It is explanatory drawing which shows the state which the cabinet connected. It is a principal part enlarged view in FIG. It is explanatory drawing which shows the state which the cabinet connected. It is a principal part expanded sectional view of a connection part. It is explanatory drawing which shows the state which the conventional cabinet connected. It is a principal part expanded sectional view of a connection part.

  The structure of the connecting part of the cabinet according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The main body 2 of the cabinet 1 has an opening 3 on the front surface. As shown in FIG. 1, the main body 2 is provided with an angle 4, and a drawer 5 containing equipment is attached to the angle 4. The door body that can be opened and closed by a pivoting operation is hinged and the opening 3 is covered. The main body 2 can also be used by connecting a plurality of bodies. The present invention relates to a structure for connecting and using a main body 2.

  Connection holes 6 for connection are provided on the left and right side surfaces of the main body 2. Connection holes 6 are provided at positions facing each other in a state where the main body 2 of the cabinet 1 is connected to the connection position. The number of connecting holes 6 can be increased or decreased as appropriate depending on the size of the cabinet 1.

  Further, a fixing piece 7 with a tap cut is attached to the inside of the main body 2 in the vicinity of one of the left and right connecting holes 6. In FIG. 4, the fixing piece 7 is formed in a hat shape, and a tap portion 7 a and a main body attaching portion 7 b are bent, and a tap hole 8 is provided in a substantially central portion of the tap portion 7 a. The tap hole 8 is located away from the side surface of the main body 2 of the cabinet 1.

  When connecting the main body 2, the fixing screw 9 is inserted into the connecting hole 6 provided on the side surface of the adjacent main body 2 from the side where the fixing piece 7 is not attached, and the fixing screw 9 is inserted into the tap hole 8 of the fixing piece 7. The body 2 is connected and fixed.

  When the main body 2 is used alone without being connected, or the connecting hole 6 on the surface that is not connected is covered with a blindfold plate 10 in order to prevent intrusion of foreign matter. The blindfold plate 10 includes a cap portion 10a and an insertion portion 10b. The insertion portion 10b is inserted into the connection hole 6 from the outside of the main body 2 and the connection hole 6 is closed with the cap portion 10a. If it is made of resin, it can be engaged with the connecting hole 6 by bending, and the operation is also simple.

  In the structure of the connecting portion configured as described above, the fixing piece 7 that receives the fixing screw 8 is attached to the main body 2. Therefore, when connecting, the trouble of pressing the nut that receives the fixing screw 8 is saved. The work can be done simply by turning the fixing screw 8 with a screwdriver. Even if the cabinet has a door that can be opened and closed by rotating the front opening of the main unit, even if the door is open, it can work alone, so it is possible to provide a cabinet with good workability. it can. Further, even when the main body is not connected, the blindfold plate 10 is used to cover the connecting hole 6 portion, and a plurality of types of conventional ones according to the diameter of the connecting hole 6 and those according to the diameter of the nut are used. Without having to prepare a blindfold, one type that fits the connecting hole is shared, greatly reducing the cost of molds and inventory management.
