Description

[Detailed description of the invention] (Industrial application field) The present invention is based on an orthogonal structure in an air filter mounting assembly frame in which a plurality of rod-like members are assembled in a lattice shape, and an air filter is mounted and fixed on the upper surface of the rod-like members. The present invention relates to a connecting device for rod-shaped members.

(Prior Art) A conventional connecting device of this kind for orthogonal rod-shaped members consists of a connecting member d fixed to a side surface b of one rod-shaped member a with a rivet c, as shown in the first figure, and a second connecting member d. As shown in the figure and the third figure, the end opening e of the other rod-shaped member a is fitted into the connecting member d,
The other rod-shaped member a is attached to the side surface b of the one rod-shaped member a.
The connecting member d and another rod-like member a are fixed with rivets c, and these rod-like members a are brought into contact with each other.
I am trying to concatenate the . Note that g in the figure indicates a notch provided on the upper surface h on the end opening e side of the other rod-shaped member a, and the sealing material i is filled in this notch,
These rod-shaped members a are airtightly connected on the upper surface h side thereof.

(Problems to be Solved by the Invention) The conventional connection device described above does not require changing the connection position of the rod-shaped member a, for example, when replacing an air filter mounted and fixed on the frame with one of a different size. If this occurs, remove one end of the connecting member d fixed to the side b of the rod-shaped member a with the rivet c, and place the rivet c in another position on the side b of the rod-shaped member a. In addition, it is necessary to plug the insertion hole of the rivet c that remains after the connecting member d is removed, and therefore it is inconvenient that it takes time and effort to connect the rod-shaped members.

(Means for Solving the Problems) The object of the present invention is to provide a connecting device for orthogonal rod-shaped members in an air filter mounting assembly frame that eliminates the above-mentioned disadvantages. In a connecting device for orthogonal rod-like members in an air filter mounting assembly frame, in which rod-like members are assembled in a lattice shape and an air filter is placed and fixed on the upper surface of the rod-like members, the longitudinal side of one rod-like member is attached to the side surface of the rod-like member. A connecting member that is slidably fitted into a groove formed along a direction, a bolt or a stud and a nut that removably fixes the connecting member at a desired position within the groove, and the rod. and a connecting plate fixed in the end opening of the rod-shaped member, the end surface of the other rod-shaped member is brought into contact with the side surface of the rod-shaped member, and a bolt or a stud and a nut are screwed into the connecting member. It is characterized in that both rod-like members are connected together with the connecting plate.
