Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0042] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only relative concepts or refer to the normal use state of the product, and should not be regarded as limiti...

Abstract

The invention relates to the technical field of residence kitchen and bathroom exhaust way systems and provides a residence fireproof exhaust valve which comprises a faceplate with a through hole and a diversion pipe arranged on the inner side of the faceplate and communicated with the through hole. The residence fireproof exhaust valve is characterized by further comprising at least two metal transmission combination mechanism in symmetric arrangement, each transmission combination mechanism comprises a base, a hooking member, a pulling member and a screw, a first hinging point is arranged on each hooking member and hinged to the corresponding base, each base is fixed on the outer wall of the diversion plate or the inner wall of the faceplate, each hooking member is provided with a second hinging point which is hinged to one end of the corresponding pulling member, a threaded hole is formed in the other end of each pulling member, each screw is extended in from the front of the faceplate to be matched with the threaded hole in the corresponding pulling member and rotates to drive the pulling member to move, and each hooking member presses the wall of an exhaust pipeline under action of the corresponding pulling member through the corresponding first hinging point and the corresponding second hinging point. By using the residence fireproof exhaust valve, the problem of defects of being instable, non-fireproof, prone to pipe breaking, time-consuming, material-consuming and power-consuming when several fireproof exhaust valves are fixed on an exhaust pipe in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of residential kitchen and bathroom exhaust duct systems, and more specifically relates to a residential fire-proof exhaust valve. Background technique [0002] The air inlet of the residential kitchen and bathroom exhaust duct system needs to be equipped with a fire-proof exhaust valve. The fire-proof exhaust valve includes a panel 10' with a through hole 11' and a flow diversion valve located inside the panel 10' and communicated with the through hole 11'. Tube 20'. At present, there are mainly the following ways to fix the fire exhaust valve: [0003] 1. Fix with expansion screws or rubber plugs. like figure 1 , figure 2 As shown, there is a mounting hole 12' reserved on the panel 10' of the fire exhaust valve. When fixing, first use a percussion drill to drill a fixing hole in the cement exhaust pipe, and the fixing hole and the mounting hole 12' on the panel 10' Correspondingly, use expansion scre...
