すことが出来る。Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to, for example, a lid of a check tube of a drainage basin. [0002] Drainage basins are arranged at the junction of domestic drainage and sewage mains, and are buried underground.
A check tube is connected from the ground to check and clean the drainage basin. The upper end of the inspection cylinder opens to the ground surface, and a lid is attached to the opening. Conventionally, as shown in FIG. 4, a screwdriver insertion groove (12) is provided on the periphery of the inspection tube lid (11), and when the lid (11) is opened, a driver is inserted into the insertion groove (12). I was open. However, when the drainage basin is used as a trapping basin or a collecting basin for drainage of miscellaneous drainage, the lid must be frequently opened and closed for maintenance such as cleaning, and each time the insertion groove is used. Inserting a screwdriver into (12) and prying it open is very troublesome work, and stress is concentrated at the insertion groove (12) when prying open with a screwdriver, which may cause damage to the driver. According to the present invention, as a means for solving the above-mentioned conventional problems, a pedestal (3) is provided through a recess (4) at the center of the upper surface of a lid (1). Position on the pedestal (3)
A boss (7) is provided, and the boss (7) is positioned on the back of the display panel (6).
Displayed on the pedestal (3) by fitting the fixing holes (8)
Mounting plate (6), the periphery of the display panel in this state (6) is intended to provide a lid inspection tube which is adapted to臨出the recess (4). DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 3. (1) is a lid of an inspection tube of a drainage basin, and the surface of the lid (1) is provided on the surface of the lid (1). Has an embossed pattern (2), a pedestal (3) formed at the center, and a pair of recesses (4, 4) formed at the left and right sides of the pedestal (3). Further the lid (1)
A peripheral groove of the driver is formed with a driver insertion groove (5). [0005] A display plate (6) is mounted on the pedestal (3) of the lid (1) by fixing means such as an adhesive, welding, or screwing. The display plate (6) is, for example, a blue chip which indicates that the drainage cell buried thereon is a trap cell. A positioning boss (7) is provided on the pedestal (3), and a positioning hole (8) on the rear surface of the display plate (6) is fitted into the boss (7) to thereby make the display plate. (6) is the pedestal
(3) It is installed at the correct position on the display board, and in this state, the display panel (6)
Is projected from the pedestal (3) to the recesses (4, 4). A packing (9) is mounted around the lid (1), and in this state, the lid (1) is fitted into the ring (10) at the upper end of the inspection tube. When removing the lid (1), as shown in FIG. 3, the finger (1) is pulled up by using the part of the display (6) of the display panel (6) that is exposed to the recess (4) as a clue. Only when the liquid etc. is clogged around the lid (1) and it becomes difficult to remove it, the insertion groove (5) of the lid (1)
Insert the screwdriver into and pry open. According to the present invention, the display (6) attached to the base (3) of the lid (1) has a clue when removing the lid (1) from the projection (4) of the display panel (6). Therefore, it is not necessary to provide a separate clue, and such a clue hardly causes stress concentration in the structure, and thus can be removed without damaging the lid.
