Specific embodiment
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As depicted in figs. 1 and 2, the invention provides a kind of guard 1, including guard main body 10 and set
The reinforcement structure 20 being placed in guard main body 10；Reinforcement structure 20 includes being arranged at guard main body 10
On one or more reinforcing rings 21 and from one or more reinforcing rings 21 to guard main body 10
Edge extend multiple support arms 22, reinforcing ring 21 and support arm 22 are made by grapheme material.
By setting reinforcement structure 20 in guard main body 10, when guard 1 is impacted, strengthen knot
The reinforcing ring 21 and support arm 22 of structure 20 are prevented from guard main body 10 and are deformed upon due to stress,
So as to improve the structural strength of guard 1, the related electric safety requirements of guard 1 is met.
As depicted in figs. 1 and 2, guard 1 can be double injection guards, or metal net mask.
Guard 1 includes guard main body 10 and reinforcement structure 20, and guard main body 10 includes the multiple being parallel to each other
Grid rib 11.The direction of arrow shown in Fig. 1 is that the direction of impact test is carried out to guard 1, when
When being impacted to guard 1 in the direction of arrows, guard main body 10 can deform along the direction of arrow, and two
Spacing between adjacent grid rib 11 can increase, i.e., as shown in Fig. 2 two adjacent grid ribs
Bar 11 can be stretched along X-direction, and reinforcement structure 20 can then prevent two adjacent grid ribs
The distance between 11 increases, prevent guard main body 10 from deforming, to strengthen the structural strength of guard 1,
Meet the associated appliance safety requirements of guard 1.
Specifically, as shown in Figure 3 and Figure 4, reinforcement structure 20 includes being arranged in guard main body 10
One or more reinforcing rings 21 and from one or more reinforcing rings 21 to guard main body 10
Multiple support arms 22 that edge extends.Reinforcing ring 21 can be polygon, or circular；Plus
The shape of strong ring 21 can be identical with the structure at the edge of guard main body 10, it is also possible to differs.In order to
So that reinforcement structure 20 prevents the spacing increase between two adjacent grid ribs 11, in multiple grids
When rib 11 is extended in a first direction, reinforcing ring 21 has multiple angle αs with multiple grid ribs 11,
Wherein, 0 °≤α≤90 °, and at least one 0 ° of 90 ° of ＜ α ＜ of satisfaction in angle α should be met.Because such as
Fruit reinforcing ring 21 is 0 ° or 90 ° with the angle α of multiple grid ribs 11, then when guard main body 10
When deforming along the direction of arrow, between reinforcing ring 21 cannot be prevented between two adjacent grid ribs 11
Away from increase.
As shown in figure 5, being provided with multiple grid ribs 11 and one or more reinforcing rings 21 and many
The mounting groove 11a that individual support arm 22 coordinates, with by mounting groove 11a by reinforcing ring 21 and support arm
22 are arranged in guard main body 10.Mounting groove 11a of the invention is arranged at the inwall of grid rib 11.
As shown in Figure 6 and Figure 7, the first end of multiple support arms 22 and one or more reinforcing rings 21
It is fixedly connected, the second end of multiple support arms 22 is fastened on mounting groove 11a.Preferably, it is multiple
The cross section at the second end of support arm 22 is trapezoidal, and the end at the second end of support arm 22 is most wide, with
Enable that multiple support arms 22 are more securely fastened in mounting groove 11a, will not be from mounting groove 11a
Interior abjection.It is highly preferred that the width of the grid rib 11 being engaged with the second end of multiple support arms 22
Degree is more than the width of other grid ribs 11, to enable the second end of support arm 22 more firm
Be fastened in mounting groove 11a, it is ensured that support arm 22 will not be with grid rib 11 in impact process
Depart from.At the same time it can also pass through to increase the contact area of support arm 22 and grid rib 11, such as increase
The height and width of holding section 22a high, further to consolidate support arm 22 with grid rib 11
Connection.
Multiple support arms 22 also include the holding section 22a being arranged between first end and the second end, engaging
There is slot, slot mounting groove 11a clampings corresponding with guard main body 10 are matched somebody with somebody on portion 22a
Close.Specifically, slot is arranged at the two side of holding section 22a, the side wall of mounting groove 11a with set
The slot for being placed in two side coordinates, so as to realize the cooperation of holding section 22a and mounting groove 11a.
As shown in Figure 8, it is preferable that setting locating dowel 22b on the second end and/or holding section 22a, it is many
It is correspondingly arranged on the bottom surface of the mounting groove 11a of individual grid rib 11 and determining that locating dowel 22b coordinates
Position hole.On the one hand, positioned when support arm 22 can be conveniently installed by locating dowel 22b；The opposing party
Face, is prevented from the impact test of guard 1 by locating dowel 22b, because impulsive force is excessive,
And cause support arm 22 to be come off from mounting groove 11a.
In embodiments of the invention one, reinforcing ring 21 be in quadrangle, each reinforcing ring 21 it is upper right
Two support arms 22 should be set, and two support arms 22 are in the angle β of multiple grid ribs 11
90°.Specifically, can by two support arms 22 be arranged on two of reinforcing ring 21 it is diagonal on, and two
Individual support arm 22 is in 90 ° with the angle β of multiple grid ribs 11.I.e. when guard main body 10 is rushed
When hitting power, two adjacent spacing of grid rib 11 then have and increase along the direction of support arm 22
Trend, and the active force of two support arms 22 in the direction along support arm 22 be it is maximum, because
This two support arms 22 can preferably prevent guard main body 10 from deforming upon.
In embodiments of the invention two, reinforcing ring 21 is rounded, the upper correspondence of each reinforcing ring 21
At least two support arms 22 are set, and at least two support arms 22 and multiple grid ribs 11 angle
β is in 90 °.I.e. when guard main body 10 is subject to impulsive force, between two adjacent grid ribs 11
Away from the trend that the direction then having along support arm 22 increases, and support arm 22 is along support arm 22
The active force in direction be maximum, therefore support arm 22 can preferably prevent guard main body 10 from sending out
Raw deformation.
Present invention also offers a kind of electric fan, electric fan includes above-mentioned guard 1, with by improving
The structural strength of guard 1 so that electric fan meets related electric safety requirements.
As can be seen from the above description, the above embodiments of the present invention realize following technology effect
Really：
Guard of the invention and electric fan, by setting reinforcement structure 20 in guard main body 10,
When guard 1 is impacted, the reinforcing ring 21 and support arm 22 of reinforcement structure 20 are prevented from
Guard main body 10 is deformed upon due to stress, so as to improve the structural strength of guard 1, meets net
The related electric safety requirements of cover 1.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for
For those skilled in the art, the present invention can have various modifications and variations.It is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included in the present invention
Protection domain within.
