Detailed Description
The embodiments of the invention are described in detail below, but the invention can be implemented in many different ways, which are defined and covered by the claims.
The utility model relates to a spiral disk and worm reducer mechanism system that is used for protective door (airtight) that probably meets with strong shock wave or destruction such as people's air defense protection, antiknock protection, safety protection, national treasury protection, the system includes Archimedes spiral disk and worm. The spiral disk is a rotating disk with spiral grooves based on Archimedes spiral lines, and the worm consists of a cylindrical worm and tooth surfaces based on Archimedes spiral lines. The Archimedes spiral surface is a ruled surface and is generated by taking a straight line as a spiral with the axis of the worm as the central line.
When the worm-shaped connecting rod works, the worm disk rotates, and the connecting rod moves through the matching between the worm groove on the worm disk and the worm. The movement of the worm enables the lock bolt to stretch or rotate, so that the protective door sealing door is locked or released.
One aspect of the present invention provides a transmission locking mechanism, and more particularly, to a worm wheel and worm reducer mechanism system for a protective door (airtight) that may encounter strong shock waves or destruction, such as civil air defense, antiknock, security, national treasury protection, etc.
The drive lock mechanism includes: a spiral disk 1 and one or more worms 2, so that the plurality of worms 2 can be driven to move simultaneously by one spiral disk 1, thereby performing locking in a plurality of directions.
The spiral plate 1 is meshed with the worm 2, the end face of the spiral plate 1 is provided with a spiral groove 3, the spiral groove 3 is generated in an Archimedes spiral mode by taking a straight line perpendicular to the spiral plate 1 as an axis and taking the straight line as an axis to the periphery, the tooth surface of the worm 2 is generated in an Archimedes spiral mode by taking the axis of the worm 2 as a center line, and the tooth surface parameter of the worm is matched with the tooth surface parameter of the spiral groove. Preferably, the tooth surface parameters of the spiral groove 3 of the spiral plate 1 are determined according to parameters such as transmission ratio.
In the technical scheme, the utility model discloses a spiral disk and worm have realized that single-stage drive ratio is big, part figure is few, the less and compact structure's of size transmission reduction gear to make simple, dependable performance and maintenance cost are low, and the auto-lock action of spiral disk and worm, can realize more reliable locking, avoid the problem of unblanking that the external force top back arouses.
Preferably, the worm tooth surface is arranged in a spiral groove of a spiral disc, the worm 2 and the spiral disc 1 have sliding and rolling at the meshing point, and the worm and the spiral disc need to use a lubricant.
The utility model also provides a protector, especially a guard gate, including foretell transmission blocked mechanical system. Since the drive-blocking mechanism is an important component of the protective structure, it determines, on the one hand, the supporting effect of the door leaf during the negative pressure or destruction phase of the shock wave and, on the other hand, the sealing pressure effect between the door leaf and the door frame. The traction performance of the locking mechanism is determined by the retarder. The worm disk and the worm reducer are reliable in operation, stable in operation, self-locking, large in single-stage transmission ratio, small in part number, small in size, compact in structure, simple to manufacture, reliable in performance and low in maintenance cost.
Preferably, the guard device further comprises a door body 4 and a door frame 5, the spiral disk 1 of the transmission locking mechanism is pivotally mounted on the door body 4, and one end of the worm 2 of the transmission locking mechanism is connected with the latch bar 7 through a connecting rod 6. Preferably, the latch 7 adopts a claw structure, a mortise structure or a lug mortise structure.
Preferably, a guide portion 8 is welded to the door body 4, and the connecting rod 6 is movably disposed in a guide hole of the guide portion 8. Preferably, the guide hole is a square hole. The guide 8 functions to move the link in a linear direction.
Preferably, the protection device comprises a plurality of latches 7, and the plurality of latches 7 can be arranged along the circumferential direction of the door body 4 as required.
In one embodiment, the door 4 is a hollow structure, and preferably, the transmission locking mechanism, the connecting rod 6 and the latch 7 are all disposed in a middle interlayer space of the door 4. The worm 2 is moved through the rotation of the spiral disk 1, the connecting rod 6 is enabled to slide in the guide part 8 in an oriented mode through the worm 2, and the guide part 8 is welded and fixed with the door body; the bolt 7 is locked with the lock box in the door frame 5 under the action of the connecting rod 6.
By adopting the technical scheme, the utility model can solve the potential safety hazard that the external force pushes back the latch bolt to cause the door leaf to lose the supporting fulcrum, thereby greatly improving the reliability of the equipment; in addition, through the linkage effect of reduction gear, shutting subassembly and hasp, can realize single action and open and close the shutting, it is rational in infrastructure to have, and the flexible operation solves the problem that the guard gate is complicated, low opening force, does not need the switching-over.
