Description
Technical field
The utility model relates to a kind of accessible high sound insulation marine fire door lifting obturator, belongs to ship domain.
Background technology
In marine fire door, the encapsulating method of labeled door is all between doorframe and door leaf, to add ring-shaped rubber weather strip, yet, some labeled door has not allowed threshold, and the inside and outside ground of labeled door has not allowed again the discrepancy in elevation, so, traditional encapsulating method just can only seal up three faces (two sides and an end face) of door, and the gap between door leaf bottom surface and ground just cannot seal by conventional method.Therefore seeking a kind of inside and outside ground of labeled door that can make does not have the discrepancy in elevation, and it is particularly important when closing, to have the accessible high sound insulation marine fire door lifting obturator of obturation effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of inside and outside ground of labeled door that can make there is no the discrepancy in elevation, and can when closing, have the accessible high sound insulation marine fire door lifting obturator of obturation effect.
The purpose of this utility model is achieved in that
A kind of accessible high sound insulation marine fire door lifting obturator, it comprises fixed frame and lifting frame, between described fixed frame and lifting frame, be connected with at least two group lifting linkage devices, in described fixed frame, be provided with sliding tray, described lifting frame is arranged at its below along the length direction of fixed frame, the bottom of described lifting frame is provided with an embedding slot, in described embedding slot, be equipped with weather strip, described lifting linkage device comprises sliding shoe, fixed block, hinge bar and back-moving spring, described sliding shoe is arranged in sliding tray, described fixed block is fixedly connected with lifting frame, described hinge bar is oblique to be articulated with between sliding shoe and fixed block, described back-moving spring is connected between hinge bar and sliding shoe, the outer end of a sliding shoe in outside is connected with a level contacts.
The outer end of described level contacts is set to outer little interior large frustum structure.
The bottom of described sliding shoe is provided with limited block.
Compared with prior art, the beneficial effects of the utility model are:
The accessible high sound insulation marine fire door lifting obturator of the utility model is installed on the door leaf bottom of marine fire door, when door leaf is opened, lifting frame is normally opened in a high position, when door leaf cuts out, lifting frame is in low level, the weather strip of its bottom contacts with ground, can guarantee the clearance seal between door leaf bottom surface and ground.Therefore this accessible high sound insulation marine fire door lifting obturator in use can make the inside and outside ground of labeled door there is no the discrepancy in elevation, and can when closing, have obturation effect, and defening effect obviously increases.

The specific embodiment
Referring to Fig. 1 ~ Fig. 5, a kind of accessible high sound insulation marine fire door lifting obturator that the utility model relates to, it comprises fixed frame 1 and lifting frame 2, is connected with at least two group lifting linkage devices 3 between described fixed frame 1 and lifting frame 2,
Described fixed frame 1 is installed on the bottom of marine fire door along its length, in described fixed frame 1, be provided with a sliding tray 1.1 arranging along its length, sliding tray 1.1 is communicated with the below of fixed frame 1, the cross section of fixed frame shown in figure 1 is " several " font, in the bottom of labeled door, offer a mounting groove, fixed frame 1 is installed in this mounting groove
Described lifting frame 2 is arranged at its below along the length direction of fixed frame 1, and the bottom of described lifting frame 2 is provided with an embedding slot 2.1 along its length, in described embedding slot 2.1, is equipped with weather strip 2.2,
Described lifting linkage device 3 comprises sliding shoe 3.1, fixed block 3.2, hinge bar 3.3 and back-moving spring 3.4, described sliding shoe 3.1 is arranged in sliding tray 1.1, sliding shoe 3.1 can slide along sliding tray 1.1, described fixed block 3.2 is fixedly connected with lifting frame 2, as a kind of preferred, top at lifting frame 2 offers holddown groove, fixed block 3.2 is fixedly installed in this holddown groove, described hinge bar 3.3 is oblique to be articulated with between sliding shoe 3.1 and fixed block 3.2, described back-moving spring 3.4 is connected between hinge bar 3.3 and sliding shoe 3.1, the bottom of described sliding shoe 3.1 is provided with limited block 3.5.
This accessible high sound insulation marine fire door lifting obturator is installed on fireproof door leaf bottom, door leaf and the doorframe of labeled door are hinged, hinged end is inner, opening end is outer end, the outer end of sliding shoe 3.1 that is positioned at one group of lifting linkage device 3 of outer end is connected with a level contacts 4, and the outer end of described level contacts 4 is set to outer little interior large frustum structure.
When labeled door is opened, while being nature, back-moving spring 3.4 is in extended state, back-moving spring 3.4 stretches, lifting frame 2 is upwards promoted, the bottom of limited block 3.5 contacts with the top of fixed block 3.2, level contacts 4 is stretched out labeled door opening end outer (being that sliding tray 1.1 is outer), and lifting frame 2, in a high position, does not contact weather strip 2.2 with ground.Shown in Fig. 1, now lifting frame 2 and weather strip 2.2 all retract (in retraction door leaf) in the fixed frame 1 of " several " font;
When labeled door is closed, level contacts 4 can contact with doorframe, doorframe compresses level contacts 4 and makes level contacts be pressed into (being in sliding tray 1.1) in labeled door, now sliding shoe 3.1 moves and drives hinge bar 3.3, hinge bar 3.3 is supported lifting frame 2 downwards, lifting frame 2 is in low level, weather strip 2.2 is contacted with ground, thereby the gap closing between door leaf bottom surface and ground is lived (when labeled door proceeds to opening by closed condition, lifting frame 2 can rise in a high position due to the restoring force of back-moving spring again, weather strip 2.2 is not contacted) with ground.
