Description

A kind of crimping type lampblack absorber air channel

Technical field

The utility model is related to lampblack absorber technical field, especially relevant with a kind of crimping type lampblack absorber air channel.

Background technology

A main part is the air channel of scroll casing shape in lampblack absorber, after oil smoke is sucked from inlet scoop, by motor from wind It is pumped into, is spiraled extractions by air channel in road import, finally from exhaust outlet discharge.

Air channel as shown in figure 1, reported procapsid 10 and back casing 20 substantially at this stage at present, and then procapsid 10 is with after Form overall by the connection of shell side 30 in the middle of housing 20.The air channel of this connection, operation is inconvenient, because procapsid 10 is with after The edge of housing 20 needs infolding, and it is not very square that front and rear housings is connected operation by shell side 30 close to the interior flanging rolled well Just, and connecting portion quality cannot ensure unification.The electric machine support of design in other existing air channel carries the stabilization of motor Degree is not high, essentially consists in being not sufficiently stable for support and steel ring connection member.

In view of above-mentioned many disadvantages, the present patent application that the present inventor proposes, use the improvement existing structure of prior art Thus shortcoming, this case produces.

Utility model content

The purpose of this utility model is to propose a kind of crimping type lampblack absorber air channel, can both simplify the production process in air channel, Product quality can be improved again.It is simultaneously of the present utility model to propose a kind of more structurally sound electric machine support.

To achieve the above object, the technical solution adopted in the utility model is as follows：

A kind of crimping type lampblack absorber air channel, including connected between procapsid, back casing, procapsid and back casing by shell side Connect；Procapsid and back casing are lived in the edge on shell side with procapsid, back casing contact site by the form winding of outward flanging.

Described shell side, it is bent into U-shaped mouth in edge at two, and procapsid and back casing each insert corresponding U-shaped mouth In realize bound edge.

The whole circle of described procapsid and the edge one of back casing is caved inward, and recess is overlapped on after the winding of shell side, and preceding Housing and back casing surface form smooth.

Described back casing is provided with support, the spiral case center that support sinks into procapsid, back casing is formed, support End is fixedly connected with motor seat ring.

Described support, is turned down by a section bar both sides and forms rib, middle punching, and overall curved, the outer end of support is taken It is connected on back casing, the inner flaring out at rib extends to wider than body, and is bent into and horizontal is connected with motor seat ring.

Described support the inner offers fixing threaded hole.

Described support the inner offers at least two screws.

Described motor seat ring is commonly connected to back casing using four supports.

Described motor seat ring is commonly connected to back casing using three supports.

The utility model is used after such scheme, with many beneficial effects：

1st, the utility model initiative proposes to realize assembling for air channel all parts by the way of crimping first, complete The full connected mode substituted in traditional handicraft, connecting portion quality can be can be visually seen so that whole production reliability is improved.

2nd, the utility model uses crimping mode, also improves the aesthetics of product surface, it is to avoid conventional coupling arrangement Each tie point at connection scar exist.

3rd, a kind of structure improved electric machine support is employed in the utility model in addition.The electric machine support will be with motor seat ring The inner increase of connection, which adds the contact area with motor seat ring, has striven for the design area of many screws, virtually Improve the degree of being connected firmly of support and motor seat ring.

4th, on the premise of support connection reliability is improved, the quantity of support according to circumstances can be suitably reduced, at one Design 3 screws in support the inner are calculated, and three supports form stable three-point mount, and there are altogether 9 screws to match somebody with somebody Close and fix.This shares 8 screws than original four electric machine supports and coordinates fixation more cost-effective, while reliability is ensured.

Embodiment

Referring to Fig. 2 to Fig. 8, the utility model preferred embodiment is further elaborated.

A kind of crimping type lampblack absorber air channel, the part procapsid 1 being mainly concerned with, back casing 2, shell side 3.Procapsid 1, after Housing 2 is directly processed making according to original planform, without interior flanging.

Depending on the length of shell side 3 is according to procapsid 1, the periphery edge lengths of back casing 2, width is the width in air channel along with bag The width on side.Main innovation point of the present utility model is two bound edges on shell side 3.As shown in Figure 4 and Figure 5, the two of shell side 3 Individual edge, bends out a U-shaped mouth 31, procapsid 1 or back casing 2 can be just snapped onto in this U-shaped mouth 31, in order to true Attractive in appearance and reliable product quality is protected, is caved inward in the edge of procapsid 1, back casing 2, the outside bound edge of U-shaped mouth 31 is just wrapped Overlay at depressed area so that surface of shell overall leveling.

The innovative point of another in the utility model is the support 4 of motor, and single support 4 is the portion of a curved dress of entirety Part, outer end is overlapped with back casing 2, is bolted.Arc part is inwardly trapped in spiral case inside, multiple supports jointly with Motor seat ring 5 is connected.Support 4 is mainly shape punching press and completely formed, and two edge strips of support 4 turn down to form rib 41, Simultaneously in order to mitigate weight, in middle punching, two ends retain the position of overlap joint, and the entirety of support 4 is curved.The outer end 42 of support 4 It is overlapped on back casing 2 and is bolted to connection.The inner 43 of support 4 extends from flaring out at rib 2, than 4, support Body is wide, and the part stretched out is bent into horizontal, so can overlap fixation with motor seat ring 5.

Support 4 in the present embodiment is due to the improvement at inner position so that the contact area increase with motor seat ring 5, because This can open up in multiple screws 44, the present embodiment above and offer 3, can so be fixed, carried with multiple spot on a support 4 The stability of high motor seat ring 5.Usual air channel support typically fixes a motor seat ring 5 jointly using 4.Due to fixed spiral shell The quantity increase of hole 44, on the premise of firmness ensures, can suitably reduce the quantity of support 4, such as can be using three supports 4, so on the premise of firmness and stability ensure, the quantity of support 4 is reduced, it is cost-effective.

Above is the utility model preferred embodiment, if other utility models people institute under the utility model concept thereof Some simple replacements and change are made, protection category of the present utility model should be all contemplated as falling within.
