Embodiment 1

[0043] see figure 1 with figure 2 , a range hood, comprising a range hood body and an anti-off hook assembly, the anti-off hook assembly includes a hanging plate 1 and a lock 2, and the range hood body includes a fan frame 3. The fan frame 3 includes a rear plate 31, and the position near the top of the rear plate 31 is hooked on the anti-drop hook assembly, thereby completing the installation of the range hood.

[0044] A hanging hole 311 is opened on the rear plate 31 of the fan frame 3 , and the lock catch 2 can pass through the hanging hole 311 to stably hang the range hood. see image 3 The projection of the upper end of the hanging hole 311 on the horizontal plane is located behind the projection of the lower end of the hanging hole 311 on the horizontal plane. The vertical height between the upper and lower ends of the hanging hole 311 is A, and the horizontal distance between the upper and lower ends of the hanging hole 311 and the projection on the horizontal plan...

Embodiment 2

[0053] see Figure 14 with Figure 15 , in this embodiment, the difference from the first embodiment above is that the locking pin 24 is cancelled, and the fourth through hole 216 corresponding to the anti-dropping pin 29 is opened on the side of the housing 21 away from the hanging plate 1, and the initial state , the anti-dropping pin 29 partially passes through the fourth through hole 216 and is exposed outside the housing 21, and the third return spring 28 is in a natural state. The height of the second through hole 253 of the lock tongue 25 is greater than the height of the push plate pin 23 . Preferably, in the initial state, the distance between the upper end of the second through hole 253 and the upper end of the push plate pin 23 is not greater than the distance between the lower end of the tongue 252 and the lower end of the housing 21, so as to avoid when the locking tongue 25 moves toward the When the upper end of the second through hole 253 abuts against the upp...

Abstract

The invention discloses an anti-off hook assembly. The anti-off hook assembly comprises a hanging plate, and is characterized by further comprising a lock catch on the hanging plate, the lock catch comprises a shell fixedly connected with the hanging plate, a push plate extending upwards out of the shell from the inside of the shell, a push plate pin connected with the push plate to synchronouslymove, and a spring bolt, and the push plate and the push plate pin can move towards or away from the hanging plate. When the anti-off hook assembly is in an initial state, the push plate and the pushplate pin are away from the hanging plate, the push plate pin penetrates through the spring bolt, and the spring bolt is limited into the shell; the anti-off hook assembly is in a locking state, the push plate and the push plate pin are close to the hanging plate, the push plate pin is separated from the spring bolt, so that the spring bolt moves downwards and partially stretches out of the shell,and the anti-off hook assembly further comprises an anti-off pin used for making the spring bolt and the shell relatively fixed in the locking state. The invention further discloses an extractor hoodusing the anti-off hook.

Description

technical field [0001] The invention relates to a mechanical connector, in particular to a detachment-preventing hook assembly and a range hood using the detachment-prevention hook assembly. Background technique [0002] The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Up-suction range hoods are usually installed directly above the cooker. At present, most range hoods on the market adopt the traditional way of hook-up structure, that is, hook...
