Description

Fan convenient to change blade

Technical Field

The utility model relates to a fan technical field specifically is a fan convenient to change blade.

Background

The fan is a driven fluid machine which increases the gas pressure and discharges the gas by means of the input mechanical energy, is a short form of habit for gas compression and gas conveying machinery in China, and generally comprises a ventilator, a blower and a wind driven generator.

The blade replacement process inside the fan is troublesome and cannot be quickly disassembled and assembled. In view of the above-mentioned drawbacks of the prior art, there is a need for further improvement to make it more practical to meet the actual use situation.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fan convenient to change blade to it is more troublesome, unable quick assembly disassembly's problem to provide the inside blade replacement process of fan in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a fan convenient to change blade, includes fan body and reference column, the internally mounted of fan body has the pivot, and is provided with the fixed column around the surface of fan body, the fixed surface all around of pivot installs hollow dead lever, and the rear of hollow dead lever is provided with the reference column, the inside arrangement of reference column has the blade.

Preferably, the hollow fixing rod is of a hollow structure, and the hollow structure inside the hollow fixing rod is wide at two ends and narrow in the middle.

Preferably, a detachable structure is arranged between the hollow fixed rod and the fixed column.

Preferably, the connection mode of the blade and the positioning column is a threaded connection.

Compared with the prior art, the beneficial effects of the utility model are that: the structure that the middle of the hollow fixed rod of the fan convenient for blade replacement is narrow and the two ends are wide can conveniently plug the fixed column from the wide end and then slide to the narrow end, so that the fixed column is convenient to fix;

the blade can conveniently be dismantled and install through the helicitic texture in the reference column to improve work efficiency.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the blade structure of the present invention.

In the figure: 1. the fan comprises a fan body, 2, a rotating shaft, 3, a fixing column, 4, a hollow fixing rod, 5, a positioning column, 6 and blades.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a fan convenient for blade replacement comprises a fan body 1, a rotating shaft 2, fixed columns 3, hollow fixed rods 4, positioning columns 5 and blades 6, wherein the rotating shaft 2 is installed inside the fan body 1, the fixed columns 3 are arranged on the periphery of the surface of the fan body 1, the hollow fixed rods 4 are fixedly installed on the periphery of the rotating shaft 2, the positioning columns 5 are arranged behind the hollow fixed rods 4, the hollow fixed rods 4 are of a hollow structure, the hollow structure inside the hollow fixed rods 4 is wide at two ends and narrow in the middle, a detachable structure is arranged between the hollow fixed rods 4 and the fixed columns 3, the hollow fixed rods 4 are narrow in the middle, the structure with two wide ends can conveniently plug in the fixed columns 3 from the wide ends and then slide to the narrow ends, so that the fixing is convenient, the blades 6 are arranged inside the positioning columns 5, the blades 6 are connected with the positioning columns 5 in a threaded manner, and the blades 6 can be conveniently detached and installed through the threaded, thereby improving the working efficiency.

The working principle is as follows: when using this fan convenient to change blade, at first the centre of hollow dead lever 4 is narrow, and the wide structure in both ends can conveniently be filled in fixed column 3 from wide end, then slides to the narrow end again to convenient fixed, blade 6 can conveniently be dismantled and install through the helicitic texture in reference column 5, thereby improves work efficiency, and this is exactly the device's whole working process.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
