In addition, preferably, as shown in Figure 1 to Figure 3, the cross-sectional plane of described limiting stopper 4 can be U-shaped, so that form slot 5 and opening.More preferably, as shown in the figure, described limiting stopper 4 can have the first side wall and second sidewall of two supporting legs that form described U-shaped, and the extended height of close described sizer 20 of wherein said the first side wall and described the first side wall is less than the extended height of described second sidewall.By this layout, the lower end that can help strut bar 1 relies on deadweight to fall into slot 5 with the pivot of sizer 20, and this will be hereinafter describes in detail in the explanation to the operation of fender guard of the present invention.
In addition, as shown in Figure 1 to Figure 3, can be provided with the stop part 8 that is used to prevent strut bar 1 outside beat on the described compartment back prop 2, thus the collision of avoiding strut bar 1 outwards to swing and cause thus.Because during sizer 20 liftings, got out of the way the segment space of below, the beat that allows strut bar 1 to take place to a certain degree, therefore preferably, this stop part 8 can be positioned at the below of described limiting stopper 4, be under the state of initial rest position shown in Figure 1 (when for example driving a vehicle) thereby be mainly used in, prevent the collision that lengthening part 7 outwards pivots and causes thus with respect to main part 6 in strut bar 1 elongation and sizer 20.Stop part 8 can be that various suitable materials are made, and is preferably flexible material (for example rubber) and makes, thereby can provide buffer protection to strut bar 1 when strut bar 1 beat.
The operation of a kind of embodiment of fender guard of the present invention is described below with reference to the embodiment of Fig. 1 to Fig. 3.Wherein, Figure 1 shows that sizer 20 is in initial equilibrium conditions, promptly do not have lifting (for example driving) state.Figure 2 shows that sizer 20 gives rise to the state of approach locking position by lifting mechanism, wherein, strut bar 1 is in elongation state.Figure 3 shows that sizer 20 gives rise to the state of latched position, wherein, strut bar 1 is in retracted mode.
As shown in Figure 1, sizer 20 is not by lifting, and sizer pillar 3 and compartment back prop 2 are substantially parallel, and strut bar 1 is in elongation state, and lengthening part 7 and main part 6 are parallel and as the prolongation of main part 6.Wherein, strut bar 1 leans in the outside of limiting stopper 4, and lengthening part 7 prevents outside beat by stop part 8.
When sizer 20 passed through the lifting mechanism lifting, as shown in Figure 2, still as the prolongation of main part 6, promptly the length of strut bar 1 was in maxim to lengthening part 7.Because the articulated position (being the upper end of main part 6) on the top of strut bar 1 arrives the maxim of the distance of limiting stopper less than the length of strut bar 1, thereby the lower end of strut bar 1 (this moment be the lower end of lengthening part 7) can't insert slot 5, thereby can not interfere the normal lifting of sizer 20.
When the locking protection need be provided the lift location of sizer 20; before sizer 20 gives rise to latched position; at first manually with lengthening part 7 pivot turnbacks; and, make the contraction in length of strut bar 1 to minimum value (being the length of main part 6) by passing attaching parts stationary body portion 6 and the lengthening part 7 of the first connecting bore 6a and the second connecting bore 7a.Then, along with the position that sizer 20 continues to give rise to a little higher than latched position, the lower end of strut bar 1 (being the lower end of main part 6 this moment) will slowly fall in the slot 5 of limiting stopper 4 under the effect of deadweight.At this moment, can make sizer 20 drop to latched position, then the lower end of strut bar 1 is supported in the slot 5, thereby an overfill protection of locking can be provided by 1 pair of sizer 20 of strut bar, as shown in Figure 3.Under state shown in Figure 3, even lifting mechanism lost efficacy, sizer 20 still can remain on latched position by strut bar 1, thereby has guaranteed in the safety of persons of descending side space to operate.In addition; pass through under the attaching parts bonded assembly state at main part 6 and lengthening part 7; sizer 20 still can give rise to higher position (for example end position) by lifting mechanism; but; in case lifting mechanism lost efficacy, the whereabouts of sizer 20 will drive strut bar 1, when the lower end of strut bar 1 drops to insertion slot 5; with stoping the continuation of sizer 20 to be fallen, play the locking protective effect.
When needs unlock protection,, make sizer 20 give rise to the position that is higher than latched position by lifting mechanism lifting sizer 20; manual teardown attaching parts then; and, make the length of strut bar 1 be elongated to maxim with lengthening part 7 pivot turnbacks, fall in the slot 5 to avoid the lower end.Then, optionally lifting or fall sizer 20.
As mentioned above, M/C only relates to lengthening part 7, i.e. the bottom of strut bar 1.By with the upper articulation of strut bar 1 in sizer pillar 3, in the time of near sizer 20 is pivoted to latched position, lengthening part 7 just can move to the position of being convenient to operate.In addition, can guarantee that sizer 20 has bigger pivoting angle when latched position, guarantee the space that the below is enough.
Wherein, strut bar 1 can be arranged on the outside of sizer pillar 3, and correspondingly, limiting stopper 4 can be arranged on the outside of compartment back prop 2.Preferably, described fender guard can and be symmetricly set on the both sides in the compartment 10 of described rear-loading compression type garbage truck for two, to support reposefully in sizer 20 corresponding both sides.
