Preferably, the middle part of the sealing plate is provided with a groove. The middle part of closing plate is provided with the recess, makes things convenient for the staff installation to dismantle.

Preferably, the bottom of the adjusting bolt is provided with a protective pad. Adjusting bolt's bottom is provided with the protection and fills up, and the setting of protection pad can prevent that adjusting bolt's screw rod from causing the damage to inflation gasbag, improves life.

Preferably, the number of the threaded holes is 2. The quantity of screw hole is 2, thereby is convenient for extrude inflation gasbag and adjust the sealed laminating power of filling up with pre-buried leak protection joint bell and spigot inner wall, and the installation is very firm.

Preferably, the sealing plate is provided with a preformed groove. Be provided with the preformed groove on the closing plate, the setting up of preformed groove makes the staff can punch it easily and take out the protection apron after pouring the completion.

Preferably, the gasket is made of a rubber material. The sealing gasket is made of rubber materials, so that the cost is low, the elasticity is good, and the processing is convenient.

Preferably, the protective pad is made of a rubber material. The protection pad is made of rubber materials, has good elasticity and cannot damage the inflatable air bag.

Therefore, the utility model discloses a pre-buried leak protection connects and uses visor plate structure possesses following advantage: the utility model discloses simple structure, the installation is dismantled all very conveniently, and stability during the use is high, can prevent that the concrete thick liquid from flowing in and causing the jam.
