Abstract
A kind of blade linking mechanism of blower fan fire-closing valve, comprise the frame (1) that fire-closing valve is installed, frame (1) upper sleeve has some square steel (2), square steel (2) is fixedly connected on blade (7) through frame (1), one end sleeve of short connecting rod (3) is upper at the square steel (2) in frame (1) outside, the other end is fixedly connected with pillar (4), pillar (4) is plugged on long connecting rod (5), long connecting rod (5) is upper by limited location cover (6), and stop collar (6) is fixed on the pillar (4) of short connecting rod (3).This linking mechanism is placed in frame outside by it, is directly subject to the impact of wind-force less, without adopting high-intensity connecting rod, thereby indirectly reduced cost of production, also reduced overall weight simultaneously.
Description
Technical field:
This practical technical field that newly relates to blower fan, more specifically to a kind of blade linking mechanism of blower fan fire-closing valve.
Background technique:
Fire-closing valve, Chang Kai, 70 degree or 280 degree are closed, and are generally located at airduct passing fire wall place, play fire shutoff effect.And fire-closing valve is realized closure and has been opened fireproofing function by the blade being connected with fire-closing valve.The existing blade being connected with fire-closing valve is generally provided with multi-disc, thereby the rotation that realizes multiple blades need to be installed linking mechanism on blade, existing vaned linking mechanism as shown in Figure 1, blade 7 is hinged on by square steel 2 on the frame 1 that fire-closing valve is installed, and on each blade 7, be all fixed with hinged seat 3 ', hinged seat 3 ' be hinged with support 4 ', support 4 ' be fixed on connecting rod 5 ' on, adopt the connecting rod 5 of this linking mechanism ' can deform for a long time under wind-force effect, thereby for the opening and closing that does not affect blade needs connecting rod 5 ' by stronger intensity, thereby connecting rod 5 ' cost higher.And adopt this linking mechanism that comparatively inconvenience is installed also.
Practical fresh content:
This practical new object is exactly the deficiency for prior art, and a kind of blade linking mechanism of blower fan fire-closing valve is provided, and it is subject to windage little, and connecting rod only needs regular tenacity, has indirectly reduced cost of production.
This practical new technology solution is as follows:
A kind of blade linking mechanism of blower fan fire-closing valve, comprise the frame that fire-closing valve is installed, frame upper sleeve has some square steel, square steel is fixedly connected on blade through frame, one end sleeve of short connecting rod on the square steel in frame outside, the other end is fixedly connected with pillar, pillar is plugged on long connecting rod, and on long connecting rod, by limited location cover, stop collar is fixed on the pillar of short connecting rod.
On described frame, form the concave station caving inward, the lower end surface of short connecting rod leans against on the upper-end surface of concave station, and described short connecting rod and the shape of long connecting rod all in the form of sheets, form flanging on long connecting rod.
Described long connecting rod is only provided with one, and square steel and short connecting rod are equipped with multiple, and the quantity of square steel, short connecting rod and blade is identical, and square steel is on same straight line.
This practical new beneficial effect is:
1, this linking mechanism is placed in frame outside by it, is directly subject to the impact of wind-force less, without adopting high-intensity connecting rod, thereby indirectly reduced cost of production, also reduced overall weight simultaneously.
2, it adopts this linking mechanism more more convenient than original linking mechanism installation, has saved manpower.
Brief description of the drawings:
Fig. 1 be former fireproof valve blade linking mechanism structural representation;
Fig. 2 is this practical structural representation that changes angle;
Fig. 3 is this practical angle structural representation that changes.
In figure: 1, frame; 2, square steel; 3, short connecting rod; 4, pillar; 5, long connecting rod; 6, stop collar; 7, blade; 3 ', hinged seat; 4 ', support; 5 ', connecting rod; 11, concave station; 51, flanging.
Embodiment:
Embodiment: see shown in Fig. 2 to 3, a kind of blade linking mechanism of blower fan fire-closing valve, comprise the frame 1 that fire-closing valve is installed, frame 1 upper sleeve has some square steel 2, square steel 2 is fixedly connected on blade 7 through frame 1, one end sleeve of short connecting rod 3 on the square steel 2 in frame 1 outside, the other end is fixedly connected with pillar 4, pillar 4 is plugged on long connecting rod 5, on long connecting rod 5, by limited location cover 6, stop collar 6 is fixed on the pillar 4 of short connecting rod 3.
On described frame 1, form the concave station 11 caving inward, the lower end surface of short connecting rod 3 leans against on the upper-end surface of concave station 11, and described short connecting rod 3 and the shape of long connecting rod 5 all in the form of sheets, form flanging 51 on long connecting rod 5.
Described long connecting rod 5 is only provided with one, and square steel 2 and short connecting rod 3 are equipped with multiple, and square steel 2, short connecting rod 3 are identical with the quantity of blade 7, and square steel 2 is on same straight line.
Working principle: this practical new linking mechanism rotates by a square steel 2, drives all short connecting rods 3 to rotate together, thereby realize the opening and closing of blade by long connecting rod 5.And this linking mechanism is arranged on frame 1 outside, not on ventilating path, thereby be directly subject to the impact of wind-force less.Only need the long connecting rod of sheet 5 and thereon moulding flanging 51 just can meet its requirement of strength, and reduced weight and cost; This linking mechanism is installed more convenient than original linking mechanism simultaneously.
