As in figure 2 it is shown, the both sides of installing plate 1 are respectively arranged with an angle 3, angle 3 to be shaped as class straight
The trapezoidal i.e. Spoondrift type in angle, angle 3 has a uncovered rotation mouth 4.The centre of installing plate 2 has
A plurality of installation counterbores and installation through hole, for connecting with permutator 11 screw.
Fig. 3 is the partial enlarged drawing of the angle of the embodiment of the present invention one.
As it is shown on figure 3, the angle of the line of same two open-mouths rotating mouth 4 in the center of circle rotating mouth 4 is spacious
Angle of release α, α are 82 °.The side rotating mouth 4 has one to limit with the arc rotating the concyclic heart of mouth 4
Position groove 5.Angle β formed by the circle center line connecting of the two ends of stopper slot 5 and rotation mouth 4 is 110 °.
Stopper slot 5 upper end is provided with an anti-skidding boss 6.
Fig. 4 is the structural representation of the protective cover of the embodiment of the present invention one.
As shown in Figure 4, there are a concave station 7, concave station 7 and the angle 3 of installing plate 1 in the end of protective cover 2
Corresponding, for angle 3 tabling.Angle 3 and the chimeric of concave station 7 are prevented from protection
Rocking of cover 2, plays the effect of firm protective cover 2.A rotation boss 8 is had, rotation on concave station 7
Turn boss 8 corresponding with the rotation mouth 4 of installing plate 1, it is possible to be interlocked with rotating mouth 4.On concave station 7
Also having a positive stop lug boss 9, positive stop lug boss 9 is corresponding with stopper slot 5, it is possible to be fastened on stopper slot
In 5.In the process that protective cover 2 opens or closes
In, positive stop lug boss 9 slides with stopper slot 5 for movement locus in stopper slot 5.When protective cover 2 closes
During conjunction, positive stop lug boss 9 is positioned at one end of stopper slot 5, after protective cover 2 fully opens, and limit convex
Platform 9 is positioned at the other end of stopper slot 5.Rotate boss 8, positive stop lug boss 9 and protective cover 2 and be integrated shape
Become.
As it is shown in figure 1, when installing plate 1 fastens with protective cover 2, the angle 3 on installing plate 1 embeds anti-
In the concave station 7 of guard shield 2, the boss 8 that rotates on protective cover 2 is snapped in the rotation mouth 4 of installing plate 1
, positive stop lug boss 9 is snapped in the stopper slot 5 of installing plate 1.
Fig. 5 is the protective cover of the embodiment of the present invention one schematic diagram when fully opening.
As it is shown in figure 1, when protective cover 2 closes, positive stop lug boss 9 is positioned at one end of stopper slot 5.Along with
Opening of protective cover 2, positive stop lug boss 9 slides to the other end with stopper slot 5 for movement locus.Such as figure
Shown in 5, when protective cover 2 fully opens, positive stop lug boss 9 slides to the other end of stopper slot 5, anti-
Angle formed by guard shield 2 and installing plate 1 is 90 °.Now, positive stop lug boss 9 is at anti-skidding boss 6
Resting in stopper slot 5 under drag effect, therefore protective cover 2 is not fall off Guan Bi.
The effect of embodiment and effect
In the present embodiment, rotary fastening preventer is provided with anti-skidding boss in one end of stopper slot,
When the positive stop lug boss with stopper slot as movement locus slides to this end, protective cover is in and fully opens
State.Now, owing to positive stop lug boss is rested in this end by the effect of anti-skidding boss resistance,
Therefore, it is possible to prevent the automatic landing of protective cover from closing.
Embodiment two
Fig. 6 is the schematic diagram during protective cover closedown of the embodiment of the present invention two.
Fig. 7 is the protective cover of the embodiment of the present invention two schematic diagram when fully opening.
As shown in Figure 6,7, in the present embodiment, rotation mouth 12 is for remaining silent, and the side rotating mouth 12 has
One stopper slot 13.Having a plurality of equidistant anti-skidding boss 14 on stopper slot 13, the present embodiment is
3.Other structures of rotary fastening preventer 15 are with embodiment one.
Fig. 8 is the partial enlarged drawing of the stopper slot of the embodiment of the present invention two.
As shown in Figure 8, when protective cover 19 fully opens, positive stop lug boss 16 slides into the A of stopper slot 13
Point, stops in this place under the effect of anti-skidding boss 14 resistance, thus prevents protective cover 19
Automatically landing Guan Bi, now, angle formed by protective cover 19 and installing plate 20 is 90 °.
During protective cover 19 is closed, when positive stop lug boss 16 slides into the B point of stopper slot 13,
Stop in this place under the effect of anti-skidding boss 17 resistance, thus prevent the automatic sliding of protective cover 19
Fall Guan Bi, and now, angle formed by protective cover 19 and installing plate 20 is 60 °.
During protective cover 19 is closed, when positive stop lug boss 16 slides into the C point of stopper slot 13,
Stop in this place under the effect of anti-skidding boss 18 resistance, thus prevent the automatic sliding of protective cover 19
Fall Guan Bi, and now, angle formed by protective cover 19 and installing plate 20 is 30 °.
When positive stop lug boss 16 slides into the D point of stopper slot 13, protective cover 19 is in closure state.
The effect of embodiment and effect
Owing to the present embodiment is provided with three equidistant anti-skidding boss on stopper slot, make the steady of protective cover
Determining open angle is 30 °, 60 ° and 90 °, therefore, it is possible to meet rotary fastening preventer
Different operating requirement.
Embodiment three
