Description

A kind of fan host mounting structure

Technical field

The utility model relates to a kind of ventilation equipment, specifically a kind of fan host mounting structure.

Background technique

It is well known that electric fan has been accepted extensively by people as a kind of reducing temperature of heatstroke prevention apparatus, electric fan is working When its working principle is that convert electrical energy into the kinetic energy of flabellum, and drive by the rotation of flabellum the flowing shape of peripheral gas flow At the wind energy that can cool down, acts directly on human body to reach using such wind energy and take away human body temperature to reach The effect of cooling.

It all includes flabellum, head, pedestal and support rod that electric fan as described above is general in structure, wherein support Bar one end is connected on pedestal, and head is connected to the other end of support rod, and flabellum is connected on the power output shaft of head, Above-mentioned electric fan head when specific works is powered and flabellum rotation is driven to achieve the purpose that generate wind energy.

But its structure of the head design occurred on the market now is all excessively complicated, production assembly cost is all higher, now Its structure of the head occurred on the market includes that drive end bearing bracket, rear end cap, front stator end cap and rear stator end cap, such head exist When specific implementation, it is necessary first in bore of stator made of closing stator setting in front stator end cap and rear stator terminal cover buckle, It then also needs to be integrally provided between drive end bearing bracket and rear end cap, that is to say, that need just fix by four sets of shells Stator, overall structure is excessively complicated, and production assembly cost is higher.

Utility model content

The purpose of this utility model is to overcome prior art there are the shortcomings that, it is simple to provide a kind of structure, installation side Just, the low a kind of fan host mounting structure of production cost.

The utility model aim is realized with the following methods: a kind of fan host mounting structure, it is characterised in that: it is wrapped The rear end cap in bottomed tube is included, drive end bearing bracket, fixed cylinder, after fan motor is mounted in fixed cylinder, fixed cylinder is mounted on rear end In lid, the open end of rear end cap is provided with several columns that are spirally connected, and drive end bearing bracket and fixed cylinder are fixedly mounted on rear end by fixed screw In lid, the outer profile of drive end bearing bracket is embedded in the inner hole of rear end cap fixed.

The drive end bearing bracket is shaped to sheet by metallic plate punching.

The drive end bearing bracket back side, which is bent with, reinforces side, reinforces side and overlaps with drive end bearing bracket.

Bearing hole is provided on the end face of the drive end bearing bracket and fixed cylinder, rotor bearing is mounted on the bearing hole It is interior.

The beneficial effects of the utility model are: 1, structure is simple, production cost is low, improves the market competitiveness；2, drive end bearing bracket is embedded Formula is mounted in the inner hole of rear end cap, the supporting role to rear end cap outer profile is played using the outer profile of drive end bearing bracket, after avoiding Cover internal, which lacks, supports caused deformation, ensure that the bearing capacity of rear end cap.

Specific embodiment

Specific further instruction is made to the utility model with reference to the accompanying drawing.A kind of fan host mounting structure, it is special Sign is: it includes the rear end cap 1 in bottomed tube, drive end bearing bracket 2, fixed cylinder 3, after fan motor 4 is mounted in fixed cylinder 3, Fixed cylinder 3 is mounted in rear end cap 1, and the open end of rear end cap 1 is provided with several columns 5 that are spirally connected, and drive end bearing bracket 2 and fixed cylinder 3 pass through Fixed screw is fixedly mounted in rear end cap 1, and the outer profile of drive end bearing bracket 2 is embedded in the inner hole of rear end cap 1 fixed.

The drive end bearing bracket 2 is shaped to sheet by metallic plate punching.

2 back side of drive end bearing bracket, which is bent with, reinforces side 21, reinforces side 21 and overlaps with drive end bearing bracket 2.

It is provided with bearing hole 5 on the end face of the drive end bearing bracket 2 and fixed cylinder 3, rotor bearing is mounted on the bearing In hole 5.

Working principle: when assembly, first fan motor and fixed cylinder is fixedly mounted, fixed cylinder is then mounted on rear end cap It is interior, it, will be in fixed cylinder integral installation rear end cap after fan host is fixed as one with fixed cylinder.The wherein front end of fixed cylinder 3 Facing peripheral equipment is equipped with connection ring 31, the outside cylinder setting of the prominent fixed cylinder 3 of connection ring 31, connection ring 31 and is located in rear end cap The column that is spirally connected cooperation.Then drive end bearing bracket is installed, wherein the outer profile of drive end bearing bracket and the similar design of the Internal periphery of rear end cap, so that preceding End cap is embedded to be mounted on the inner hole of rear end cap, plays the supporting role to rear end cap using the outer profile of drive end bearing bracket.Then Pass through drive end bearing bracket using fixed screw, the global column 5 that is spirally connected for being located at 1 open end of rear end cap of connection is spirally connected fixation, by each accessory It is fixed as one.Wherein, it in order to increase the enabling capabilities of drive end bearing bracket, is bent in this case at 2 back side of drive end bearing bracket and reinforces side 21, added Strong side 21 is overlapped with drive end bearing bracket 2.Fan host is supported jointly with drive end bearing bracket using side is reinforced, so that simplifying knot in this case Structure while reducing production cost, has stronger bonding strength and support force, therefore can be widely used to promote.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.
