Description
Technical Field
The invention belongs to the technical field of bank safety equipment, and particularly relates to a pressing and sealing mechanism of a vault door.
Background
The prior general bank vault door is not provided with a compression sealing mechanism, the vault door cannot be sealed and waterproof, the high-grade vault door has a sealing and waterproof requirement, after the vault door is closed, the vault door with the waterproof requirement is arranged, and a rubber sealing strip between a door stop and a door plate of the vault door has a compression requirement, so that the reliable compression sealing mechanism is required to meet the high sealing performance requirement and the high waterproof requirement when the bank vault door is closed.
Disclosure of Invention
The technical problems to be solved by the invention are as follows: the problem existing in the prior art is solved, and the pressing sealing mechanism for the vault door is provided, so that the requirements of high sealing performance and high waterproof performance of the vault door after the vault door is closed are effectively met, and the technical performance and the service performance of the vault door are improved.
The technical scheme adopted by the invention is as follows:
the utility model provides a vault door compresses tightly sealing mechanism, the compact heap that has the inside groove is fixed on the stand of vault door frame, big bottom plate is fixed on the vault door plant, install fixed square piece on the big bottom plate, spring extension board and worm gear mechanism, the worm end is connected fixedly with the hand wheel, the major axis rear end is connected with the worm wheel, the major axis front end is connected with the long cover with eccentric column with the flat key, the long cover can slide on the major axis axial, the long cover inserts in the big round hole of square piece, the long cover is Zhou Kaicao outward, the anterior part of groove is the helicla flute, the rear part of groove is the circular arc groove, corresponding to this, the screw section of countersunk pin screws into the screw hole of square piece, the cylinder end of countersunk pin inserts in the groove of long cover periphery; in addition, the pulley passes through the round pin to be installed at fork-shaped seat front end, and fork-shaped seat passes the little round hole of square piece, and fork-shaped seat tail end supports the locking plate and passes through square head screw rod fastening, and the guide pin rear end welds in another round hole of locking plate, and the guide pin front end inserts in the locating hole of square piece, square head screw rod periphery suit spring, and spring front end withstands the locking plate, and the rear end is by spring extension board roof pressure location, and the round hole on the spring extension board is passed to square head screw rod's rear end.
In the technical scheme, two saddle screw holes are formed in the end of the worm, and the end of the worm is fixedly connected with the hand wheel of the vault door through the two saddle screws.
Working principle and advantages:
the hand wheel is rotated, the hand wheel drives the worm to rotate through two seam riding screws at the end head of the worm, the worm drives the worm wheel, the worm wheel drives the long shaft to rotate, and the long shaft drives the long sleeve to rotate through the flat key; when the vault door is closed, the long shaft and the long sleeve rotate anticlockwise, as the countersunk head pin is inserted into the groove at the periphery of the long sleeve, and the front part of the groove is a spiral groove, the long sleeve axially displaces while rotating, the eccentric column at the front end of the long sleeve also forwards advances while rotating and stretches into the inner groove of the compacting block, when the long shaft and the long sleeve continue to rotate, the countersunk head pin enters the circular arc groove without the spiral angle at the periphery of the long sleeve, at the moment, the eccentric column does not forwards any more, but continues to upwards rotate until the top of the inner groove of the compacting block is propped against, the vault door is inwards compacted, and the countersunk head pin reaches the top of the circular arc groove at the periphery of the long sleeve, and the long sleeve cannot anticlockwise rotate, so that the eccentric column is kept at the compacting position. When the vault door is opened, the hand wheel drives the worm wheel and the worm to rotate, the long shaft and the long sleeve rotate clockwise, the eccentric column at the front end of the long sleeve rotates downwards, the compression state is released, when the long sleeve rotates continuously to enable the countersunk head pin to enter the spiral groove part at the periphery of the long sleeve, the long sleeve also moves backwards axially while rotating continuously, the eccentric column at the front end of the long sleeve moves backwards together and leaves the inner groove of the compression block, and the vault door is allowed to be opened. At this time, the notch on the cylindrical step in the middle of the long shaft corresponds to the lug of the locking plate, after the vault door is opened, the pulley loses the blocking of the pressing block, the locking plate is pushed forward under the action of the spring force, and the locking plate lug enters the notch of the cylindrical step in the middle of the long shaft, so that the long shaft cannot rotate, and the long sleeve and the eccentric column cannot move forward after exiting, thereby effectively protecting the eccentric column from being broken when the vault door is closed, and preventing the eccentric column from blocking the closing.
The invention has the advantages of ingenious design, reasonable structure and reliable operation, effectively realizes that the door plate and the rubber strip of the door shield are reliably pressed when the vault door is closed, has good sealing performance and waterproof performance, and prevents the eccentric column from being broken when the eccentric column blocks the next door closing or is closed when the door is opened, thereby greatly improving the technical performance and the service performance of the vault door.
