Abstract
The invention discloses a safe sealed door which comprises a door frame, a door plate, a screw rod shaft, a gland nut component, a sliding block, a handwheel, levers, a support, a spherical press head, a T-shaped guide rod and a guide disk, wherein the T-shaped guide rod is arranged between the gland nut component and the sliding block; the guide disk is arranged between the T-shaped guide rod and the screw rod shaft; a cam slot is formed on the gland nut component; and a T-shaped slot is formed on the guide disk. As the structure of the safe sealed door is linearly telescopic, the safe sealed door does not drive the sliding block to rotate during operation; more levers can be arranged along a circumference, so pressing force is more uniform; as the T-shaped guide rod can only do normal motion along the T-shaped slot of the guide disk under the push of the cam slot of the gland nut component, error operation can be avoided even a friction force on the mechanism is larger; and a dustproof protection device can be arranged on the gland nut component, so that interference caused by rotation of the levers can be prevented.
Description
Technical field
The present invention relates to a kind of security closed protective door.
Background technology
Existing safe sealed door, as shown in Figure 1, when need are opened, counter-clockwise direction is rotated handwheel 2, screw axis 7 drives clamp nut 5 along the axis moving linearly, clamp nut 5 rotates with screw axis 7 after running into spacer pin 3 end faces, the slide block 6 that is fixed on the clamp nut drives lever 7 rotatablely moving at bearing 8 interior dos contractions and certain angle, it is spacing after the cannelure on the rear clamp nut 5 of turning an angle contacts with spacer pin 3 side bus, lever is retracted to minimum, as shown in Figure 2, retaining mechanism is in open mode; When the need locking door, clockwise direction rotates handwheel 2, screw axis 7 drives clamp nut 5 by lead angle frictional force and rotates together, the slide block 6 that is fixed on the clamp nut drives lever shaft 7 rotatablely moving at bearing 8 interior do elongations and certain angle, it is spacing after the cannelure on the rear clamp nut 5 of turning an angle contacts with spacer pin 3 side bus, lever is stretched to maximum, as shown in Figure 3, when being rotated further handwheel, clamp nut 5 band movable sliders 6 are along lever shaft axis moving linearly, lever 7 rotates take bearing 8 as fulcrum, realizes compressing weather strip between doorframe and the door-plate thereby be applied to pressure on the doorframe by spherical indenter 9, reaches airtight purpose.
Adopt said structure to have following shortcoming:
1, when needing the multiple spot pressing airtight, owing to affected after shrinking by slide block, lever, this structure can not realize the multiple spot pressing when the external frame girth of door is larger;
2, in door body locking process, meet frictional force when large (greater than lead angle frictional force) such as mechanism, lever is not when being elongated to the greatest requirements position, and clamp nut will be with movable slider to produce misoperation along lever shaft axis moving linearly;
3, when opening, because slide block and lever be all with the clamp nut rotation, it is larger to take up room, inconvenience pressing nut component is increased prevent dust, protector.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art, thereby a kind of safe sealed door is provided.
A kind of safe sealed door comprises doorframe, door-plate, screw axis, pressing nut component, slide block, handwheel, lever, bearing and spherical indenter, and it also includes T-shaped guide rod and positioning disk, is provided with T-shaped guide rod between pressing nut component and slide block; Between T-shaped guide rod and screw axis, be provided with positioning disk; Described pressing nut component is provided with cam path, and described positioning disk is provided with T-shaped groove.
Be provided with weather strip between described doorframe and the door-plate.
Adopt the beneficial effect of technique scheme to be:
1, the present invention is because its structure is linear telescopic, and course of action is not with movable slider to rotate, and along circumference more lever can be set, and makes pressure force more even;
2, the present invention even frictional force is met when larger by mechanism, can not produce misoperation because T-shaped guide rod under the pressing nut component cam path promotes, can only move as normal direction along the T-shaped groove of positioning disk yet;
3, the present invention can arrange dustproof, protector to pressing nut component, not rotated by lever and interferes.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail:
Such as Fig. 4, shown in 5, when the need locking door, after pulling door-plate 11 and doorframe 10 closures, clockwise direction rotates handwheel 17, screw axis 14 drives pressing nut component 15 and rotates together, T-shaped guide rod 12 is connected as a single entity with slide block 16, the left end head limit its can only be under the promotion of the cam path 22 of pressing nut component 15 along the T-shaped groove moving linearly of positioning disk 13, thereby promote slide block 16 drive levers 18 and make stretching motion along bearing 19 centers, make spherical indenter 20 stride into doorframe 10 locking faces, screw axis 14 is after turning to the α angle, T-shaped guide rod 12 slides into extreme position 2, at this moment positioning disk 13 hole dimensions are greater than T-shaped guide rod 12 left end diameters, and T-shaped guide rod 12 left ends lose restriction, when being rotated further handwheel 17, screw axis 14 will drive pressing nut component 15 along its center line moving linearly, lever 18 will rotate along balance pivot in the bearing 19 21, reach to drive spherical indenter 20 and progressively compress weather strip between doorframe 10 and the door-plate 11, finally reach the airtight purpose of door-plate 11 and doorframe 10.
When need are opened, counter-clockwise direction is rotated handwheel 17, screw axis 14 drives pressing nut component 15 moving linearlies, same T-shaped guide rod 12 is moving linearly separately along positioning disk 13 holes, after pressing nut component 15 is run into screw axis 14 end faces, will be with screw axis 14 rotations, T-shaped guide rod 12 left end T connectors enter the T-shaped groove of positioning disk 13, the T-shaped guide rod 12 of pressing nut component 15 cam paths, 22 reverse promotions falls back on extreme lower position along the T-shaped groove of positioning disk 13, slide block 16 drives lever 18 and is contracted to position 1 along bearing 19 centers simultaneously, and hand wheel rotating stops.
The operating principle of retaining mechanism is: after door and doorframe closure, rotation hand wheel, utilize mechanism to stretch out first lever, and then realize compressing weather strip between doorframe and the door-plate by locking nut along the screw axis moving linearly, finally reach the airtight purpose of door and doorframe.
The present invention is widely used in the manufacturing of colliery, non-coal mine sealed door, safety door.
