Description

[0001]
[Industrial applications]
The present invention relates to a connecting tool for connecting a plurality of racks each of which has a column at four corners, and a column formed between adjacent ends of the column to form a frame.
[0002]
[Prior art]
FIG. 5 shows a conventional connection tool for connecting a plurality of racks each having a frame formed by erected pillars at four corners and continuously connecting end portions of adjacent pillars with pillars. was there. That is, through holes 32 are provided near the corners of the upper surface and the bottom surface of the rack 31, respectively, and the through holes 32 are aligned with each other so that bolts 33 are inserted from the inside of the frame of one rack 31 to the inside of the frame of the other rack 31. Was inserted and tightened and fixed with a nut 34. Further, a screw hole is provided on a side surface of the rack 31 and screwed and fixed with a screw 36 via a connection fitting 35.
[0003]
[Problems to be solved by the invention]
However, according to the above-described conventional rack coupling tool, since a bolt, a nut, a screw, and the like are tightened and fixed using a tool, there is almost no space for a tool to enter when a communication device or the like is mounted inside the rack 31, In addition, there is a disadvantage in that connection / construction in a narrow place is extremely troublesome. Further, in the case where the connection fitting 35 is screwed and fixed from the side face with the screw 36, there is a disadvantage that the connection fitting 35 projects and hinders, and the connection fitting is exposed and the appearance is poor.

A tool body is provided, a guide body for inserting a shaft body which can be protruded by sliding the connector body and sliding a knob of the shaft body to fix the shaft body in a protruding state is provided in the connecting body, The body is provided with a locking piece in the vicinity of the distal end, and a knob for sliding the shaft body between the substantially middle portion and the end portion, and is urged in a projecting direction by a spring body. In the vicinity of the corner, a through hole through which the shaft body can be inserted is provided. A locking piece insertion portion through which the locking piece can be inserted is continuously provided, the shaft body of the coupling tool is protruded from a through hole of one rack, and is inserted into a through hole of the other rack. By locking the knob of the body along the guide groove, the locking piece rotates from the locking piece insertion portion of the through hole and locks with the frame of the rack, and the racks are connected to each other. It is.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The locking piece is made to protrude from the through-hole of one rack, inserted through the through-hole of the other rack, and slide and fixed the knob of the shaft along the guide groove to secure the locking piece. The rack rotates from the locking piece insertion portion and locks with the frame of the rack, and the racks are connected to each other.
[0006]
【Example】
One embodiment of the rack connecting tool according to the present invention is shown in FIGS. Hereinafter, the present invention will be described with reference to these drawings.
[0007]
The rack 1 is provided with columns 2 standing at four corners, and a frame 4 formed by connecting columns 2 adjacent to each other with pillars 3. A connecting tool 5 for connecting a plurality of racks 1 is provided with a connecting tool body 6 near a corner inside the frame 4 of the rack 1, and the connecting tool main body 6 can be protruded by sliding. A guide groove 9 for inserting the body 7 and sliding the knob 8 of the shaft body 7 to fix the shaft body 7 in a protruding state is provided. A knob 8 for sliding the shaft 7 is provided between the substantially middle portion and the end portion, and the knob 8 is urged in a protruding direction by a spring body 11, and a shaft is provided near the outer corner of the frame 4 of the rack 1. A through-hole 12 through which the body 7 can be inserted is provided, and the through-hole 12 is provided with locking piece insertion portions 13, 13 through which the locking pieces 10, 10 can be inserted.
[0008]
The shaft 7 of the connecting tool 5 is projected from the through hole 12 of one rack 1, inserted into the through hole of the other rack 1, and the knob 8 of the shaft 7 is slid along the guide groove 9 and fixed. Then, the locking pieces 10, 10 rotate from the locking piece insertion portions 13, 13 of the through hole 12 to lock with the frame 4 of the rack 1, and the racks 1, 1 are connected.
[0009]
As shown in FIG. 4, the locking piece 20 of the shaft 17 of the connecting tool 15 and the locking piece insertion portion (not shown) of the through hole (not shown) may be provided at one place. It can be changed appropriately without departing from the scope.
[0010]
In the present invention, the racks are stacked vertically and connected to each other.However, the present invention is not limited to this, and the connecting tool may be used to connect racks arranged side by side in the horizontal direction. No problem.
[0011]
【The invention's effect】
As described above, the rack connecting device according to the present invention includes a plurality of racks formed by erected pillars at least at four corners and continuously connecting end portions of adjacent pillars with pillars to form a frame. A connecting tool for connecting, wherein a connecting tool main body is provided near a corner inside the frame of the rack, and a shaft that can be protruded by sliding is inserted into the connecting tool main body. A guide groove for sliding the knob of the body to fix the shaft body in a protruding state is provided, and a locking piece is provided near the tip of the shaft body, and the shaft body is slid between the substantially middle portion and the end portion. The rack is urged in a protruding direction by a spring body, and a through hole through which the shaft body can be inserted is provided near an outer corner of the frame of the rack, and the locking piece is provided in the through hole. Are continuously provided with a locking piece insertion portion through which a shaft can be inserted. From the through hole of the other rack, slide the knob of the shaft along the guide groove and fix it, so that the locking piece rotates from the locking piece insertion portion of the through hole. By locking with the frame of the rack and connecting the racks to each other, there is an effect that the racks can be connected easily and reliably without using a tool. This is particularly effective in connection and construction in a narrow place where it is difficult to carry the rack. Further, since the connecting tool is not exposed to the outside of the rack, there is an effect that the appearance is good.
