Abstract
A kind of buckled type frame of blower fan fire-closing valve, comprise two long margin frames (11) and the short frame (12) that form rectangular frame, long margin frame (11) forms and links together with short frame (12), long margin frame (11) forms respectively chamfering (13) with the two ends of short frame (12), the chamfering (13) of long margin frame (11) is close together mutually with short frame (12) chamfering (13), the two ends of described long margin frame (11) form respectively the side plate (111) extending laterally, on side plate (111), form some catching grooves (112), the two ends of short frame (12) form buckle teeth (121), buckle teeth (121) on short frame (12) is withheld on long margin frame (11) through the catching groove (112) of long margin frame (11).It is easy for installation, and manufacturing efficiency is high, has reduced welding personnel and welding equipment, has saved cost of production.
Description
Technical field:
This practical technical field that newly relates to blower fan, more specifically to a kind of buckled type frame of blower fan fire-closing valve.
Background technique:
Fire-closing valve, often opens, and 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 are placed on fire-closing valve frame, and fire-closing valve frame is arranged in fire-wall.Existing fire-closing valve frame is generally welded to form rectangular frame by a plurality of side plates that separate, and fire-closing valve frame welding job lengthening consuming time, working efficiency is not high, and cost of production is higher simultaneously.
Model utility content:
This practical new object is exactly the deficiency for prior art, and a kind of buckled type frame of blower fan fire-closing valve is provided, and it is easy for installation, and manufacturing efficiency is high, has reduced welding personnel and welding equipment, has saved cost of production.
This practical new technology solution is as follows:
A kind of buckled type frame of blower fan fire-closing valve, comprise two long margin frames and the short frame that form rectangular frame, long margin frame and short frame form and link together, the two ends of long margin frame and short frame form respectively chamfering, the chamfering of long margin frame is close together mutually with short frame chamfering, the two ends of described long margin frame form respectively the side plate extending laterally, on side plate, form some catching grooves, the two ends of short frame form buckle teeth, and the buckle teeth on short frame is withheld on long margin frame through the catching groove of long margin frame.
Described long margin frame and short frame are on the steel tank of same Contraband font, on channel-section steel, form 3 V-shaped groove mouths, notch is cut apart steel tank and is shaped to long margin frame and short frame, long margin frame and short frame bending forming are rectangular frame, the two ends of described channel-section steel form respectively corner cut, corner cut is respectively the chamfering of long margin frame and short frame, and the chamfering of short frame and long margin frame forms the V-shaped groove mouth of channel-section steel, and the angle of described short frame and the chamfering of long margin frame is 45 °.
On described long margin frame and short frame, all form flanging, the side plate of long margin frame forms little buckle teeth, and little buckle teeth is withheld on short frame through the flanging of short frame.
This practical new beneficial effect is:
1, its another whole steel tank bending is the rectangular frame of fire-closing valve frame, and is fixed together by withholding, thereby without adopting welding again, has saved personnel's configuration of welding and welded required equipment, has greatly reduced labour force and cost of production.
2, the bending of the fire-closing valve frame of this practical new structure is easy to assembly, has reduced built-up time, has greatly improved manufacturing efficiency.
Accompanying drawing explanation:
Fig. 1 is this practical new structural representation;
Fig. 2 is this practical structural representation that changes angle;
Structural representation when Fig. 3 is this practical frame expansion;
Partial structurtes schematic diagram when Fig. 4 is this practical frame expansion.
In figure: 1, channel-section steel; 11, long margin frame; 12, short frame; 13, chamfering; 14, V-type notch; 111, side plate; 112, catching groove; 113, little buckle teeth; 121, buckle teeth.
Embodiment:
Embodiment: see shown in Fig. 1 to 4, a kind of buckled type frame of blower fan fire-closing valve, comprise two long margin frames 11 and the short frame 12 that form rectangular frame, long margin frame 11 forms and links together with short frame 12, long margin frame 11 forms respectively chamfering 13 with the two ends of short frame 12, the chamfering 13 of long margin frame 11 is close together mutually with short frame 12 chamferings 13, the two ends of described long margin frame 11 form respectively the side plate 111 extending laterally, on side plate 111, form some catching grooves 112, the two ends of short frame 12 form buckle teeth 121, buckle teeth 121 on short frame 12 is withheld on long margin frame 11 through the catching groove 112 of long margin frame 11.
Described long margin frame 11 and short frame 12 are on the steel tank 1 of same Contraband font, on channel-section steel 1, form 3 V-shaped groove mouths 14, notch 14 is cut apart steel tank 1 and is shaped to long margin frame 11 and short frame 12, long margin frame 11 and short frame 12 bending formings are rectangular frame, the two ends of described channel-section steel 1 form respectively corner cut, corner cut is respectively the chamfering 13 of long margin frame 11 and short frame 12, the chamfering 13 of short frame 12 and long margin frame 11 forms the V-shaped groove mouth 14 of channel-section steel 1, and the angle of described short frame 12 and the chamfering 13 of long margin frame 11 is 45 °.
On described long margin frame 11 and short frame 12, all form flanging, the side plate 111 of long margin frame 11 forms little buckle teeth 113, and little buckle teeth 113 is withheld on short frame 12 through the flanging of short frame 12.
Working principle: this practical new long margin frame 11 and short frame 12 are cut out and formed by same channel-section steel bending stamping, only need bend at the V-type notch place of channel-section steel 1 can be by the framework of long margin frame 11 and a rectangle of short frame 12 compositions, and effectively framework is fixed by buckle teeth 121 briquettings, thereby without consume manpower time-consuming again as adopting welding procedure.
