The fixed structure of range hood cold plate
Technical field
The utility model relates to a kind of range hood, specifically is a kind of fixed structure of range hood cold plate.
Background technology
Near-suction type oil smoke suction machine is one of three major types main flow range hood in the market; Compare with other two types of range hoods (Chinese style range hood and European range hood); Have unique advantages such as do not meet and discuss, save space, suction are strong, the market share enlarges markedly in recent years.The near-suction type oil smoke suction machine that contains the cold plate folding behind the unlatching cold plate, can be dismantled oily net and impeller easily, the convenient cleaning and maintenance; After closing cold plate, can prevent that oil smoke from pouring in down a chimney the taint of odour phenomenon that causes to the kitchen from public flue, institute takes up space little, more brief, the fashion in kitchen, thereby enjoy favor.As shown in Figure 3, Chinese patent document number CN201748513U discloses a kind of range hood on 02 16th, 2011 and has comprised exhaust fume collecting hood, oil cleaner screen and connecting portion.Exhaust fume collecting hood has into mouth.Oil cleaner screen is connected in exhaust fume collecting hood, and over against advancing mouth.Connecting portion is connected between exhaust fume collecting hood and the oil cleaner screen, and comprises grab and the buckle corresponding with grab.Grab is grab and buckle card jail when in exhaust fume collecting hood, pushing away oil cleaner screen with the fit system that is connected of buckle, and grab and buckle are thrown off when in exhaust fume collecting hood, pushing away oil cleaner screen again.This design can partly be improved the installation of cold plate, but there is following weak point in above-mentioned structure in using: the described buckle of this technical scheme, the hidden danger that exists inner jump ring to lose efficacy; In the process of dismounting cold plate, may draw bad jump ring, after jump ring lost efficacy; Buckle can't be closed again, causes grab can't be connected with buckle, and promptly cold plate can't be connected with exhaust fume collecting hood; Cause lampblack absorber normally to use, bring shortcomings such as using inconvenience.
The utility model content
The purpose of the utility model aims to provide a kind of fixed structure of range hood cold plate of rational in infrastructure, esy to use, safe and reliable, long service life, to overcome weak point of the prior art.
Press the fixed structure of a kind of range hood cold plate of this purpose design; Comprise the cold plate that is arranged on the casing; Both are fixedly connected through bindiny mechanism, and said bindiny mechanism comprises buckle and grab with matching, and buckle is made up of with the elasticity press section that is connected above that fixed part; Its architectural feature is that grab is made up of with the active fastening block that is connected above that clamping hook seat; Active fastening block is rotationally connected through pin and clamping hook seat, also be connected with back-moving spring between the two, but elasticity press section elasticity is fastened in active fastening block.
The fixed part of said buckle is fixed on casing or the cold plate, and the clamping hook seat of grab is fixed on cold plate or the casing.
Said bindiny mechanism be positioned at casing and cold plate above or below.
The quantity of said bindiny mechanism is more than 1.
The beneficial effect of the utility model is: active fastening block and clamping hook seat junction are provided with back-moving spring, and active fastening block can rotate, and the elastic force of active fastening block and clamping hook seat is less than the self-lock force of buckle; Even it is so firmly excessive in taking off the process of cold plate; Active fastening block also can cushion excessive power through rotating, and separates with dop, guarantees that buckle and grab can not damage; It has advantages such as easy to use and reliable simultaneously, helps to promote the good looking appearance degree of range hood.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1, Fig. 4-Fig. 8, the fixed structure of this range hood cold plate comprises the cold plate 2 that is arranged on the casing 1; Both are fixedly connected through bindiny mechanism; Said bindiny mechanism comprises buckle 4 and grab 5 with matching, and buckle 4 is made up of with the elasticity press section 42 that is connected above that fixed part 41, and its grab 5 is made up of with the active fastening block 52 that is connected above that clamping hook seat 51; Active fastening block 52 54 is rotationally connected with clamping hook seat 51 through pinning; Also be connected with back-moving spring 53 between the two, but elasticity press section 42 elasticity be fastened in active fastening block 52, like Fig. 5, shown in Figure 6.
Elasticity press section 42 1 ends are rotationally connected through jump ring (not marking among the figure) and fixed part 41, and an other end extends outward dop 43, and dop 43 is fastened with active fastening block 52 elasticity and is connected.
The fixed part 41 of buckle 4 is fixed on the casing 1 through screw, and the clamping hook seat 51 of grab 5 is fixed on the cold plate 2 through screw.The bindiny mechanism of present embodiment is positioned at the below of casing 1 and cold plate 2, also can be arranged on both tops according to design demand.The quantity of bindiny mechanism is 2.
When cold plate 2 is installed; In casing 1, push away cold plate 2, elasticity press section 42 is stressed will to be contained in the host cavity (not marking among the figure) of fixed part 41, simultaneously; Elasticity press section 42 can drive dop 43 and snap in the active card fast 52; As shown in Figure 4, card is firm each other with buckle 4 to make grab 5, thereby cold plate 2 is mounted on the casing 1.
During dismounting cold plate 2, in casing 1, push away cold plate 2 once more, but because elasticity press section 42 has resilience; Eject from the host cavity of fixed part 41 42 stressed backs, elasticity press section; Simultaneously, elasticity press section 42 drives dop 43 separates from active card fast 52, as shown in Figure 7; Make the grab 5 in mutual card jail disconnected from each other, thereby cold plate 2 is disassembled from casing 1 with buckle 4.When interior cold plate 2 dynamics that push away when not enough, not resilience of elasticity press section 42, dop 43 fails never to separate from active card fast 52 routinely; At this moment, the cold plate 2 if user continues to pull outward is because spring 53 dynamics of grab 5 are less than the dynamics of the jump ring between elasticity press section 42 and the fixed part 41; The active fastening block 52 of grab 5 begins to rotate around pin 54; Effectively the pulling force of interruptible customer is thrown off until active fastening block 52 and dop 43, and cold plate 2 is disassembled from casing 1 smoothly; Avoid damaging buckle 4 or grab 5, improved the reliability of cold plate 2 mounting structures.
When once more cold plate 2 being installed, repeating abovementioned steps and get final product, easy to operate.
Second embodiment
Referring to Fig. 2, the fixed structure of this range hood cold plate is that with the first embodiment main distinction fixed part 41 of buckle 4 is fixed on the cold plate 2 through screw, and the clamping hook seat 51 of grab 5 is fixed on the casing 1 through screw.
Other do not state part, with first embodiment, repeat no more.
