Description

Anti-theft sealing easily opens and closes the flap device

The utility model belongs to a kind of flap device.

Well head in the city is all located to take off greatly and is covered no-console condition, the many bolt ups of the flap of some tuns and storage tank.Therefore, often cause a lot of troubles because of flap.As: the Sewage well cover on the road is lost damage and is easily caused traffic accident; Facility well lids such as telecommunications, optical cable, coal gas, fire-fighting, heat supply lose that to decrease the future trouble bring also bigger; Some tuns and the long-term corrosion of storage tank flap are difficult for again opening

For overcoming the above-mentioned defective of prior art, the utility model aims to provide a kind of anti-theft sealing and easily opens and closes the flap device, and it can be used on various well heads, tun and the storage tank flap, and not only anti-theft sealing, and opening and closing is convenient.

For achieving the above object, the utility model mainly is made of mouth circle, movable flap and start-stop system.Upper end one side of mouthful circle has fixedly flap of a small half of month shape.In on the mouth circle along and fixedly flap be arranged with sealing member in the groove on edge in straight, but movable flap buckle closure on the mouth circle in along and fixedly flap seal on the edge and by sealing member and its realization in directly.Cover at fixing port and to be provided with a through hole.The upper end of screw mandrel with lock is installed in the through hole of fixing flap among the start-stop system, and universal cross nut is equipped with in the screw mandrel portion in stage casing, and the lower end is installed on the locating support on mouthful circle lower inner wall.The two ends of main shaft are installed on mouthful axle bed that the circle inwall is established, center fixed one main force's arm of main shaft, and the breach of the other end of main force's arm links with universal cross nut.Center fixed at main shaft has passive arm, and the other end of passive arm connects with actuating lever by little axle.One end of actuating lever is provided with adjustable bolt, and the other end of actuating lever connects with the supporting seat axle that movable port covers, and its termination load is on the support rim that mouth circle inwall is established.Also fix two passive arms on the symmetric position of main shaft, the other end of passive arm connects by the supporting seat axle that yoke plate and movable port cover.Fixedly also be provided with dust cap in the through hole of flap and be held in screw mandrel with lock upper end.

Unlatching activity flap takes off dust cap earlier, and the spanner of being with key is inserted screw mandrel with lock upper end, the back rotary screw rod left by lock, and universal cross nut is moved downward, and main force's arm just drives main shaft and rotates, force passive arm and actuating lever the movable port caping to be risen, to reach purpose of opening by supporting seat.Turn adjustable bolt, can adjust the opening angle of movable port lid.Desire to close movable flap, with screw mandrel backward rotation with lock, universal cross nut upward movement, main force's arm drive the main shaft counter-rotating, and the supporting seat that forces passive arm and actuating lever to draw movable port to cover moves downward, till closing sealing tight.Screw mandrel with lock is locked, pull up key and spanner, cover dust cap again and get final product.

Owing to take above-mentioned technical solution, the utlity model has simple in structure, open and close laborsaving, anti-theft sealing, advantage such as safe and reliable.
