Technical field

This utility model is related to a kind of side-suction type range hood, more particularly to a kind of filter screen quickly can be positioned and fixed Side-suction type range hood filtering net fixed device.

Background technology

The fixed form of existing side extraction cooking fume extractor filter screen is generally divided into screw, and directly fixed or pressing plate is fixed, using spiral shell Nail fixed form, when dismounting filter screen must release screw completely, cumbersome, inconvenient operation, and pressing plate fixed form is adopted, Pressing plate does not have spacing, 360 ° of rotations of meeting, operates inaccurate and easily error.

Utility model content

This utility model mainly solves existing side-suction type range hood filter screen fixed form operation inconvenience and the skill for easily malfunctioning Art problem；Quickly can position there is provided a kind of filter screen and fixed side-suction type range hood filtering net fixed device.

In order to solve above-mentioned technical problem, this utility model mainly adopts following technical proposals：

A kind of side-suction type range hood filtering net fixed device of the present utility model, on the choke circle panel of blower fan, is used for Fixed filter screen, the fixing device includes screw rod, is sleeved on screw rod and set and buckle are trapped on mutual corresponding buckle, described Screw rod is fixedly arranged on edge on the choke circle panel, and on the buckle, set and buckle are embedded with spring between trapping, the spring Drift the distance between is trapped more than set on buckle and buckle, and spring upper end bears against the lower surface of set, under spring End bears against the upper surface trapped, and the struck side covered on buckle compresses the edge of the filter screen, by covering on rotary buckle, makes Struck side is covered on buckle and compresses filter screen, the fixation of filter screen becomes accurate and convenient, meanwhile, inside set the rotation that spring makes to cover on buckle Damping is larger, set struck side on buckle is not deflected easily, it is ensured that the reliability and firmness of filter screen clamping.

Preferably, lower surface is covered on the buckle is provided with shrinkage pool, the buckle central authorities that trap are provided with projection, the shrinkage pool Projection is matched and is accommodated with the projection, and projection central authorities are provided with inner chamber, and the intracavity bottom and shrinkage pool bottom are equipped with screw rod Installing hole, cavity heights are less than the spring free length, and spring is embedded in inner chamber, and spring upper end bears against the recessed of set Bottom hole face, lower spring end bear against the inner chamber bottom surface trapped, and spring-compressed is simultaneously embedded in buckle is trapped, compact conformation and U.S. See, meanwhile, under elastic force effect, jack-up upwards is covered on buckle and against screw head, cover on buckle and in use will not Deflection is produced, the fixation more safety and reliability of filter screen is made.

Preferably, the struck side bottom surface covered on the buckle takes the form of inclined plane, its bottom surface proximally to distal end gradually updip, When on buckle, the rotation of set struck side compresses filter screen, inclined struck side bottom surface can gradually compress filter screen, and operation is accurate, compress jail Gu, also will not filter screen be caused to damage.

Preferably, the fixing device also includes cover on the buckle the spacing of struck side rotational angle for limiting Post, the limited post are two, the both sides of the screw rod that is placed in and are fixedly arranged on the choke circle panel, are set in screw or so Limited post is put, is limited the angle of stirring covered on buckle, operation is accurate.

The beneficial effects of the utility model are：By covering on rotary buckle, set struck side on buckle is made to compress filter screen, filter screen Fixation become accurate and convenient, meanwhile, inside setting spring makes the damping due to rotation covered on buckle larger, makes to cover struck side not on buckle Can deflect easily, coordinate the limited post of screw rod both sides, it is ensured that reliability and firmness that filter screen is installed.

Specific embodiment

Below by embodiment, and accompanying drawing is combined, the technical solution of the utility model is described in further detail.

Embodiment：The side-suction type range hood filtering net fixed device of the present embodiment, as shown in Figures 2 and 3, installed in blower fan On 1 panel of choke circle, for fixing filter screen 2, as shown in figure 1, fixing device 3 includes screw rod 31, is sleeved on screw rod and be mutual On corresponding buckle, set 32 and buckle trap 33, and screw rod is fixed on the upper edge of choke circle panel, the lower surface design covered on buckle There is shrinkage pool, the central design that buckle is trapped has projection, and shrinkage pool is matched with projection and accommodates projection, in projection central design has Chamber, intracavity bottom and shrinkage pool bottom are machined with screw rod installing hole, and screw rod can be by corresponding screw rod installing hole and choke circle face Plate is affixed, is embedded with spring 34 in the lumen, and the drift of spring is more than cavity heights, and spring is sleeved on screw rod, thereon End bears against the bottom surface of set shrinkage pool, and lower end bears against the bottom surface of inner chamber of trapping, and fixing device is also included for limiting card The limited post 35 of set struck side rotational angle is buckled, limited post is two, the both sides of the screw rod that is symmetrically placed in and is fixed on choke On circle panel.

During assembling, spring is inlaid in the inner chamber that buckle is trapped, then buckle is trapped imbeds in the shrinkage pool covered on buckle, Finally screw rod is pierced in the screw rod installing hole that set and buckle are trapped on buckle and edge on choke circle panel is fixed on, completes to fix The assembling of device.

During use, struck side will be covered on buckle and will rotate the limited post that reclines, and filter screen lower end will be inserted on choke circle panel After in two slots of air port back-up ring, whole filter screen reclines choke circle panel, finally will stir reverse rotation by set on buckle, and make card Buckle set struck side to be pressed on filter screen, complete the installation of filter screen.

Disassembly, cleaning filter screen is such as needed, struck side rotation only need to will be covered on buckle and is reclined to limited post, filter screen departs from panel, most Extract out in air port back-up ring slot by filter screen from choke circle panel afterwards.
