Description

Shell structure of cross-flow fan

Technical Field

The utility model relates to a cross-flow fan shell.

Background

At present, cross-flow fan is widely used for laser instrument, the air conditioner, the air curtain equipment, the desiccator, the hairdryer, on household electrical appliances and the cereal combine, among the prior art cross-flow fan shell generally includes the left socle, the right branch frame, go up deep bead and lower deep bead, wherein the structure of left socle and right branch frame is usually by the mainboard that sets up with preceding deep bead and fixed mainboard of back deep bead and mainboard one side of bending and constitutes, set up the fixed fan position of fixed orifices on the piece of bending, its fixed mode has lead to that it can not adapt to more and more diversified equipment fixing is required, and its structure has also led to the weak yielding scheduling problem of compressive capacity.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a strong compressive capacity's of cross-flow fan shell structure with multiple mounting means.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a tubular fan's shell structure, includes left socle 1, right branch frame 2, goes up the deep bead 3 and takes curved deep bead 4 down, and left socle 1 and right branch frame 2 structure are the same and the symmetry sets up in the both sides of last deep bead 3 and deep bead 4 down, left socle 1 includes that square 5 and 5 four sides of mainboard are equipped with keep away from the face 6 of bending of 4 directions of deep bead, be equipped with motor fixed orifices 7 on mainboard 5, be equipped with the fixed orifices 8 that are used for fixed fan casing on the face 6 of bending, square shock pad 9 has been cup jointed in the activity of 6 outer walls of the face of bending, the face 6 of bending is 90 with 5 contained angles of mainboard, be provided with the screw thread in the fixed orifices 8, 2 are no less than to the quantity of fixed orifices (8).

Compared with the prior art, the beneficial effects of the utility model are that: reasonable in design, simple structure has improved the intensity of shell under the prerequisite that does not improve the cost, uses the fixed orifices and the square antivrbration pad that are equipped with on four faces of bending to make cross-flow fan's mounting means more diversified, can satisfy multiple installation demand.

Drawings

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

wherein, 1-left support, 2-right support, 3-upper wind shield, 4-lower wind shield, 5-main board, 6-bending surface, 7-motor fixing hole, 8-fixing hole, and 9-square shockproof pad.

Detailed Description

The invention will be further explained and illustrated with reference to the following examples, which are not intended to limit the invention in any way.

Example 1

Referring to fig. 1, a casing structure of a cross-flow fan comprises a left bracket 1, a right bracket 2, an upper wind shield 3 and a lower wind shield 4 with an arc shape, wherein the left bracket 1 and the right bracket 2 are identical in structure and are symmetrically arranged at two sides of the upper wind shield 3 and the lower wind shield 4, the left bracket 1 comprises a square main board 5 and bending surfaces 6 which are arranged on four sides of the main board 5 and are far away from the lower wind shield 4, the main board 5 is provided with a motor fixing hole 7, the main board 5 is provided with a through hole, the through hole 5 is respectively used for an output shaft of the motor and a positioning piece to extend into the shell to be connected with the wind wheel, the bending surface 6 is provided with a fixing hole 8 for fixing a fan shell, the fixing hole can be used for fixing the shell of the cross-flow fan in a screw fixing mode, the outer wall of the bending surface 6 is movably sleeved with a square shockproof pad 9, the shockproof pad has a shockproof effect, and the shockproof pad can be used for clamping type installation when screw-free installation is needed. The angle between the bending surface 6 and the main board 5 is 90 degrees.

And the threads are arranged in the fixing holes 8, and the number of the fixing holes 8 is not less than 2, so that the fixing device can be used for various fixing modes.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
