Abstract

The utility model relates to a filter screen for a smoke exhaust ventilator. The filter screen comprises a lock which is provided with a lock barrel and is used for installing the filter screen on the smoke exhaust ventilator. The filter screen is characterized in that the filter screen also comprises two or more upper oil filtering slots and lower oil filtering slots with arc-shaped cross sections; the openings of the upper oil filtering slots and the lower oil filtering slots are opposite and staggeredly matched, so as to form an upper gap between two adjacent upper oil filtering slots and a lower gap between two adjacent lower oil filtering slots, and gaps are reserved between the walls of the upper oil filtering slots and the lower oil filtering slots to form oil smoke filtering passages; the lock barrel is arranged between the upper oil filtering slots and the lower oil filtering slots; and the filter screen also comprises a frame (2) for fixing the upper oil filtering slots and the lower oil filtering slots, and a hole allowing the bolt of the lock barrel to protrude out is arranged on the frame. The filter screen has the advantages of low production cost, full use of plate materials, esthetic appearance, no deformation, and so on; and thin product can be manufactured.

The utility model content

The utility model is to overcome the deficiencies in the prior art and provide a kind of production cost low, can utilize the sheet material material fully, a kind of smoke exhaust ventilator filter screen that good looking appearance, product can not be out of shape.

In order to achieve the above object, the utility model is achieved in that it is a kind of smoke exhaust ventilator filter screen, comprises the lock that filter screen is installed in the core with lock on the smoke exhaust ventilator; It is characterized in that: comprise that also the curved upward filtration oil groove of section more than two reaches oil strain groove down, relative and the cooperation that intermeshes of the opening of upper and lower oil strain groove, thereby thereby making to produce between the adjacent two upward filtration oil grooves to go up produces gap formation filtering oil smoke passage down between gap and adjacent twice the oil strain grooves; Described lock core is located between the upper and lower oil strain groove; The frame that also comprises fixing upper and lower oil strain groove is provided with the hole that the dead bolt of lock core can stretch out on frame.

Be provided with slot at described scuncheon and reach slot down, the two ends of described upward filtration oil groove are located in the slot, and the described two ends of oil strain groove down are located at down in the slot.

Be provided with the upper support bar of reinforcement and supporting role at the middle part of described upward filtration oil groove; Be provided with the lower support bar of reinforcement and supporting role at the described middle part of oil strain groove down.

Described lock also comprises back-moving spring; Described lock core is " H " shape, and the wide part of its two arm constitutes dead bolt, and narrow part constitutes guide post, and two guide posts are located at respectively in the adjacent two upward filtration oil grooves, and its wide, narrow transition portion forms a ladder position; The position corresponding with the ladder position is provided with the default position of matching with it on described upward filtration oil groove, thus the sliding position of restriction lock core, back-moving spring one end is set on the guide post, and the other end is resisted against on the upward filtration oil groove.

Described lock comprises also and also comprises handwheel that it is by being bolted on the lock core.

The utility model advantage compared with prior art is, production cost is low, can utilize the sheet material material fully, and good looking appearance, product can not be out of shape, and product can be done thinlyyer.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

Shown in Fig. 1 to 4, it is a kind of smoke exhaust ventilator filter screen, comprises the lock that filter screen is installed in the core with lock 4 on the smoke exhaust ventilator; Characteristics of the present utility model are: comprise that also the curved upward filtration oil groove 1 of section more than two reaches oil strain groove 5 down, relative and the cooperation that intermeshes of the opening of upper and lower oil strain groove, thereby thereby making to produce between the adjacent two upward filtration oil grooves to go up produces gap 5a formation filtering oil smoke passage down between gap 1a and adjacent twice the oil strain grooves; Lock core 4 is located between the upper and lower oil strain groove; The frame 2 that also comprises fixing upper and lower oil strain groove is provided with the hole 21 that the dead bolt 41 of lock core can stretch out on frame.During work, the oil smoke of being taken out is drawn into from last gap 1a, and behind the gap under the process between oil strain groove 5 and the upper and lower oil strain groove, from gap 5a outflow down, the oil after the filtration drops in the upper and lower oil strain groove again.

In the present embodiment, be provided with slot 22 in frame 2 inboards and reach slot 23 down, the link socket connection of frame; The two ends of upward filtration oil groove 1 are located in the slot, and the upward filtration oil groove side on both sides also is located in the slot; The two ends of following oil strain groove 5 are located at down in the slot, and the following oil strain groove side on both sides also is located at down in the slot; Be provided with the upper support bar 11 of reinforcement and supporting role at the middle part of upward filtration oil groove 1, the upper support bar is concordant with the both sides of upward filtration oil groove, and it can be supported in the slot like this; Be provided with the lower support bar 51 of reinforcement and supporting role at the middle part of following oil strain groove 6, the lower support bar is concordant with the end of following oil strain groove, and it can be supported on down in the slot like this.

Lock also comprises back-moving spring 7 and handwheel 3; Lock core 4 is " H " shape, and the wide part of its two arm constitutes dead bolt 41, and narrow part constitutes guide post 42, two guide posts and is located at respectively in the adjacent two upward filtration oil grooves 1, thereby can make its directed moving, and its wide, narrow transition portion forms a ladder position 421; The position corresponding with the ladder position is provided with the default position 12 of matching with it on the upward filtration oil groove, and when lock core was mobile in the frame 2, when being displaced to default position as ladder, moved toward interior more default position restriction ladder position, thereby limit the sliding position of lock core; Back-moving spring 7 one ends are set on the guide post, and the other end is resisted against on the upward filtration oil groove; Handwheel 3 is fixed on the lock core 4 by bolt 6, and the handled easily lock core is having the breach 52 that holds to go into bolt 6 on the oil strain groove down.During installation, mobile handwheel 3, dead bolt 41 can move in frame 2, can be installed in the utility model on the smoke exhaust ventilator this moment, unclamps handwheel, under the effect of back-moving spring 7, dead bolt moves outward and inserts in the smoke exhaust ventilator, and the utility model and smoke exhaust ventilator are fixed, and installs.When need are pulled down filter screen, also be mobile handwheel, dead bolt moves in frame, can take off filter screen.
