押圧する。 Alternatively, as shown in FIG.
A pin 6 is fixed horizontally, a bolt 8 is screwed into a block 7 loosely fitted to the pin 6, and the iron lid 2 is pressed against the frame 1.

しかし、第８図に示した方法は、ブロツク７が
損傷した場合には、ピン６を枠１から取外して新
たなものと交換する必要があるが、ピン６の取外
しに手間がかかる。 However, in the method shown in FIG. 8, if the block 7 is damaged, it is necessary to remove the pin 6 from the frame 1 and replace it with a new one, but removing the pin 6 is time-consuming.

[Purpose of invention]

この考案は、鉄蓋を枠に押圧するための部材の

Recess 1 formed in frame 1 into which iron lid 2 is fitted
It is removably installed horizontally and in parallel inside A. The pin 9 consists of a threaded rod 10 and a cap nut 11 that is screwed into the threaded rod 10. One end of the pin 9 (the left end in FIG. 2) is connected to a pin hole 1D formed in one side wall 1B of the recessed portion 1A formed in the frame 1.
inserted within. One end (the right end in FIG. 2) of the cap nut 11 is inserted into a pin hole 1E formed in the other side wall 1C of the recessed portion 1A formed in the frame 1. The middle of the threaded rod 10 is formed to have a rectangular cross section. To attach the pin 9 to the concave portion 1A of the frame 1, first shorten the length of the pin 9 as shown in FIG. 4, then shorten both ends of the pin 9 as shown in FIG. Push the pin 9 until it is inserted into the pin holes 1D and 1E, and finally turn the square cross section of the threaded rod 10 with a spanner or the like to fix it between the side walls 1B and 1C of the recessed portion 1A. do.
