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 safe seal protection 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 nuts 5 along the axis moving linearly, run into spacer pin 3 end faces after clamp nut 5 rotate with screw axis 7, be fixed in slide block 6 on the clamp nut and drive levers 7 and bearing 8 in, do rotatablely moving of contraction and certain angle; Cannelure after turning an angle on the clamp nut 5 contacts the back with spacer pin 3 side bus spacing; Lever is retracted to minimum, and is as shown in Figure 2, and retaining mechanism is in open mode; When need locking door, clockwise direction rotates handwheel 2, and screw axis 7 drives clamp nut 5 through lead angle frictional force and rotates together; The slide block 6 drive lever shafts 7 that are fixed on the clamp nut are done rotatablely moving of elongation and certain angle in bearing 8, the cannelure on the back clamp nut 5 that turns an angle contacts the back with spacer pin 3 side bus spacing, and lever is stretched to maximum; As shown in Figure 3; When being rotated further handwheel, clamp nut 5 drives slide block 6 along lever shaft axis moving linearly, and lever 7 is that fulcrum rotates with bearing 8; Thereby the pressure through spherical indenter 9 is applied on the doorframe is realized compressing the weather strip between doorframe and the door-plate, reaches airtight purpose.
Adopt said structure to have disadvantage:
1, when needing the multiple spot pressing airtight, owing to influenced after shrinking by slide block, lever, this structure can not realize the multiple spot pressing when the external frame girth of door is bigger;
2, in door body locking process, meet frictional force when big (greater than lead angle frictional force) like mechanism, lever is not when being elongated to the greatest requirements position, and clamp nut will drive slide block and 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 bigger 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 type guide rod and positioning disk, between pressing nut component and slide block, is provided with T type guide rod; Between T type guide rod and screw axis, be provided with positioning disk; Said pressing nut component is provided with cam path, and said positioning disk is provided with T type groove.
Be provided with weather strip between said doorframe and the door-plate.
Adopt the beneficial effect of technique scheme to be:
1, the present invention is because its structure is a linear telescopic, and course of action does not drive slide block and rotates, and along circumference more lever can be set, and makes pressure force more even;
2, the present invention even frictional force is met greatly the time by mechanism, can not produce misoperation because T type guide rod promotes can only to move as normal direction along positioning disk T type groove down at the pressing nut component cam path yet;
3, the present invention can be provided with 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 done further explain:
Like Fig. 4, shown in 5, when need locking door, after pulling door-plate 11 and doorframe 10 closures; Clockwise direction rotates handwheel 17, and screw axis 14 drives pressing nut component 15 and rotates together, and T type guide rod 12 is connected as a single entity with slide block 16; The left end head limits it can only be at the T type groove moving linearly of the promotion lower edge positioning disk 13 of the cam path 22 of pressing nut component 15, drives levers 18 and makes stretching motion along bearing 19 centers thereby promote slide block 16, makes spherical indenter 20 stride into doorframe 10 locking faces; Screw axis 14 is after turning to the α angle, and T type guide rod 12 slides into extreme position 2, and at this moment positioning disk 13 hole dimensions are greater than T type guide rod 12 left end diameters; T type 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, and lever 18 will rotate along balance pivot in the bearing 19 21; Reach and drive spherical indenter 20 and progressively compress the 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, and screw axis 14 drives pressing nut component 15 moving linearlies, and same T type 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 type guide rod 12 left end T connectors get into the T type groove of positioning disk 13, and pressing nut component 15 cam paths 22 reverse promotion T type guide rods 12 fall back on extreme lower position along the T type groove of positioning disk 13; Slide block 16 drives lever 18 and is contracted to position 1 along bearing 19 centers simultaneously, and handwheel rotates and stops.
The operating principle of retaining mechanism is: after door and doorframe closure; Rotation hand wheel; Utilize mechanism to stretch out lever earlier, and then realize compressing the weather strip between doorframe and the door-plate along the screw axis moving linearly, finally reach door and the airtight purpose of doorframe through locking nut.
The present invention is widely used in the manufacturing of colliery, non-coal mine sealed door, safety door.
