Abstract
The utility model relates to a middle-link radiating piece for a cross-flow fan provided with a stress dispersion block, which comprises a circular median plate and fan blades, wherein the median plate and the fan blades are integrally formed, one end surface of the median plate is fixedly connected with the fan blades, and a fan blade embedding groove of the other middle-link radiating piece is formed on the other end surface of the median plate; and the middle-link radiating piece for the cross-flow fan provided with the stress dispersion block is characterized in that at least two radial bulges uniformly distributed in the radial direction are arranged on a central hole of the median plate; or at least two axial bulges uniformly distributed in the axial direction are arranged on the median plate between the fan blades and the central hole, and the axial bulges are arranged on one or two axial end surfaces of the median plate. By adopting the structure, the radial or axial bulges play the role of strengthening the injection point; and meanwhile, when the drop test is carried out, the effect of dispersing stress is achieved, so that the median plate can be prevented from being fractured after falling down.
Description
Technical field
The utility model relates to a kind of axial-flow fan, especially the middle joint loose mail of axial-flow fan leaf.
Background technique
Prior art as shown in Figure 3, saves the middle plate 1 that loose mail comprises ring in a kind of improved axial-flow fan leaf at present, flabellum 2, middle plate 1 and flabellum 2 one-body molded making, middle plate 1 one end faces and flabellum 2 are fixedly connected, and the embedded groove 3 of the flabellum of joint loose mail in another is arranged on other end.Existing problems are: when carrying out drop test, concentrate by advancing glue point place stress, middle plate is from advancing the fracture of glue point.
Summary of the invention
The purpose of this utility model is: provide a kind of and disperse the middle joint loose mail of the axial-flow fan of piece with stress, the stress at the enterprising glue point of plate place during it can disperse effectively improves the intensity of entering glue point place, when preventing to fall in plate from from advancing the fracture of glue point.
The utility model is achieved in that a kind of middle joint loose mail that disperses the axial-flow fan of piece with stress, the middle plate and the flabellum that comprise ring, in plate and flabellum is one-body molded makes, middle plate one end face is fixedlyed connected with flabellum, the embedded groove of the flabellum of joint loose mail in another is arranged on other end, and its special way is: at least two radially, equally distributed radial protrusions are arranged on the center hole of middle plate;
Or on the middle plate between flabellum and the center hole, there are at least two vertically, equally distributed axial projection, axial projection to be arranged on middle one or two axial ends of plate.
Describedly a kind ofly disperse the middle joint loose mail of the axial-flow fan of piece with stress, its special way is: on the axial end of the middle plate of the radially inner side of flabellum the belt stress dispersion slot is arranged, during ring stress dispersion slot is arranged on one of plate or two axial ends.
Describedly a kind ofly disperse the middle joint loose mail of the axial-flow fan of piece with stress, its special way is: on the axial end of plate, on the middle plate between adjacent two axial projection arc stress dispersion slot is arranged during axial projection is arranged on; On another axial end of middle plate the belt stress groove is arranged.
Describedly a kind ofly disperse the middle joint loose mail of the axial-flow fan of piece with stress, its special way is: on two axial ends of plate, on the middle plate between adjacent two axial projection arc stress dispersion slot is arranged during axial projection is arranged on.
Describedly a kind ofly disperse the middle joint loose mail of the axial-flow fan of piece with stress, its special way is: described radial protrusion is curved, square or trapezoidal.
Describedly a kind ofly disperse the middle joint loose mail of the axial-flow fan of piece with stress, its special way is: described axial projection is prismatic, cylindrical or hemisphere.
The utility model is a kind of to disperse the middle joint loose mail of the axial-flow fan of piece with stress, and at least two radially, equally distributed radial protrusions are arranged on the center hole of middle plate; Or on the middle plate between flabellum and the center hole, there are at least two vertically, equally distributed axial projection, axial projection to be arranged on middle one or two axial ends of plate.Because adopt such structure, radial protrusion or axial projection play reinforcement effect to entering glue point place; Simultaneously, when falling, can also play the effect of the component of stress, so can prevent when falling middle plate fracture effectively.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of middle joint loose mail that disperses the axial-flow fan of piece with stress, the middle plate 1 and the flabellum 2 that comprise ring, middle plate 1 and flabellum 2 one-body molded making, middle plate 2 one end faces are fixedlyed connected with flabellum 2, the embedded groove 3 of the flabellum of joint loose mail in another is arranged on other end, three radially, equally distributed radial protrusions 4 are arranged on the center hole 11 of middle plate 1;
Described radial protrusion 4 is curved, square or trapezoidal.
As further improvement of this embodiment: on the axial end of the middle plate 1 of the radially inner side of flabellum 2, belt stress dispersion slot 5 is arranged.During belt stress dispersion slot 5 can be arranged on one of plate 1 or two axial ends.
As shown in Figure 2, three vertically, equally distributed axial projection 6 are arranged on the middle plate 1 between flabellum 2 and the center hole 11.
As further improvement of this embodiment, on the middle plate 1 between adjacent two axial projection 6, arc stress dispersion slot 7 is arranged.
Described axial projection 6 can be prismatic, cylindrical or hemisphere.
Above-described only is preferential mode of execution of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
