ック装置に関する。BACKGROUND OF THE INVENTION The present invention relates to a hinged frame and an iron cover at one end of a manhole.
For sewage pipes, when the iron lid is closed, the lid fits inside the keyhole to prevent rainwater from flowing into the manhole and lock the weight key to the L-shaped hook on the receiving frame to lock the key. to hold the stop Me state. To open the iron cover with a burl, insert the engagement projection of the burl into the keyhole and press the cover with the burl to open the keyhole. The weight key is removed from the L-shaped hook of the receiving frame, and the abutment portion of the weight and the deburring are stopped by the engaging projection protruding from the tip of the burl.
Because accepted 10b, joined to 10b 'stop return governor weight
Converting mechanism to open a pull over and Technology of iron <br/> lid as it is at hand bar in the partition wall of iron lid case for rainwater pipe, and be taken out Succoth than governor weight the lid body, the lid present accept parts 15 and 15 at the engaging projection Removing the body from the governor weight at the same bar '
Is pressed down to prevent the weight from deburring. 12a, 12a '
To engaged with, the manhole iron lid was to be able to open the iron lid in the configuration to bar so that the governor weight is unexpected preempted by yourself and be multiplied out of Succoth the key to stop the return of the governor weight Related to a lock device.

Description of the Related Art Conventionally, in a lock device for a manhole iron cover, when a manhole is constructed under a road, rainwater and dust enter the manhole from a keyhole of the iron cover. In order to prevent this drawback, a seat plate (lid) via rubber packing on the weight
There are things that Ri attached was purified by preparative. This structure requires a step as the members attach to Ri taken through the screw packing governor weight, the rubber must be periodically replaced easily aging, has the disadvantage that the cost. Also, when the keyhole is not closed by the lid depending on the purpose of use, that is, when rainwater flows from the keyhole into the manhole, it is necessary to remove the rubber packing and the seat plate from the weight and replace it with another member. Had the disadvantage of requiring complicated operations.

できる。As described above, according to the present invention, when the lid main body is applied to an iron lid, when the iron lid is closed, the upper surface of the lid has a height substantially coincident with the upper surface of the iron lid. The keyhole in the lid is closed so that rainwater does not enter the receiving frame. Further, by using Remove and collected from Tetsufuta the lid body, keyhole of Tetsufuta is from communicating the manhole inside and outside, can be introduced rainwater poured down the road to the receiving frame in from keyhole. If strained facilities to Matafuta body Tetsufuta, the abutment of the governor weight at back stopper plate accept a lid body to be operated at bar engaging convex portion to depress and rotate the governor weight Because the lid is locked on the upper surface of the L-shaped hook of the receiving frame, the key can be released from the L-shaped hook of the receiving frame and unlocked, and the weight is screwed by holding the right and left pieces together. The shaft protruding from both sides of the lid main body can be easily fitted into the shaft hole of the weight so that the lid main body can be pivotally mounted on the weight so as to be rotatable. Also, when the lid body is removed from the weight,
To engage the engagement protrusion of the bar from the bar accepted part of the governor weight on the way back and stopper auxiliary section of the governor weight stopping the rotation in the clockwise direction of the governor weight to the bar until disengage from Tetsufuta, governor weight the key to prevent the hanging only stop the hook portion of the receiving frame, can be applied to easily quickly receiving frame the Tetsufuta. Rotation and stopper structures in the clockwise direction of governor weight by providing the only way back and stopper receiving joined to abutment of the governor weight around the axis of the Matafuta body does not require a complicated member other the structure is simple, it is possible to perform opening operation of the iron lid can make rotation stopper plate of the governor weight at the lid body rapidly reliably.
