Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refering to Fig. 1 to Fig. 4, the undercarriage for the aircraft that the utility model embodiment provides includes connecting bracket 11, contacted to earth
Bar 12 and extension rod 13, the bar 12 that contacts to earth is horizontally disposed and is removably attachable to the lower end of at least two connecting brackets 11, contact to earth
At least one end of bar 12 is provided with limited post 121, and extension rod 13, which has, is available for the cavity 131 that bar 12 inserts that contacts to earth, the side of cavity 131
Limit card slot 132 is offered on wall, the bar 12 that contacts to earth removably is inserted in cavity 131, and the bar 12 that contacts to earth is in insertion cavity 131
During, direction of the limited post 121 along the longitudinal axis different from extension rod 13 is caught in limiting card from the opening of limit card slot 132
The bottom of groove 132.
The quantity at least two of connecting bracket 11, more than two connecting brackets 11 are spaced and are parallel to each other and set
Put, ensureing the fuselage of aircraft smoothly can be arranged on undercarriage.Connecting bracket 11 is preferably portal-framed structure.Contact to earth bar 12
It is horizontally disposed with and can be contacted with ground, ensures that undercarriage can be stood on ground.The bar 12 that contacts to earth is two, two bars 12 that contact to earth
It is parallel to each other, is connected to the lower end of left and right two of each connecting bracket 11.Contact to earth bar 12 both ends can set it is spacing
Post 121, so, the every bar 12 that contacts to earth can connect two extension rods 13, so as to farthest increase accounting for for undercarriage
Ground area, to ensure the stability of aircraft.
Specifically, as shown in Figures 2 to 4, contact to earth bar 12 end insertion cavity 131 when, limited post 121 also enter it is spacing
The opening of neck 132, with contacting to earth, bar 12 inserts the bottom of cavity 131, and limited post 121 is also caught in the bottom of limit card slot 132,
Under the cooperation of limited post 121 and limit card slot 132, the bar 12 that can prevent from contacting to earth is pullled down by external force to be taken off out of cavity 131
Go out.
Limit card slot 132 could be arranged to the profiled shapes such as L-shaped, arc, and so, limited post 121 is relative to limit card slot
132 motion track is not straight line, so as to which direction of the limited post 121 along the longitudinal axis different from extension rod 13 is from limiting card
The opening of groove 132 is caught in the bottom of limit card slot 132.Specifically, as shown in Figures 2 and 3, contacting to earth on the inside of limited post 121
Elastomeric element 122 is arranged with bar 12, elastomeric element 122 is used to, when the bar 12 that contacts to earth inserts cavity 131, to extension rod 13 apply
Outside elastic force, 132 curved setting of limit card slot.Elastomeric element 122 is, for example, spring.The bar 12 that contacts to earth is connecting with extension rod 13
Need to relatively rotate when connecing, in rotation process, direction of the limited post 121 along the longitudinal axis different from extension rod 13 is from limiting card
The opening of groove 132 is caught in the bottom of limit card slot 132.
Further, in order to prevent limited post 121 from producing movement after being caught in the bottom of limit card slot 132, such as Fig. 3 and Fig. 4
Shown, in the present embodiment, the bottom of limit card slot 132 is provided with the holding tank 133 towards the extension of the opening direction of cavity 131, so that
Limited post 121 is obtained to be contained in holding tank 133.Because limited post 121 is contained in holding tank 133, and in elastomeric element 122
Under effect, limited post 121 can not produce movement on the direction of the longitudinal axis of extension rod 13, and then ensure undercarriage
Fastness.
Referring to Fig. 2, in the present embodiment, undercarriage also includes adapter sleeve 14, and one end of adapter sleeve 14 is provided with the
One jack 141, adapter sleeve 14 are provided with the second jack 142, the first jack 141 and second relative to the other end of the first jack 141
The opening direction of jack 142 is mutually perpendicular to, and the bar 12 that contacts to earth is inserted in the first jack 141, the lower end insertion second of connecting bracket 11
In jack 142.In order to ensure that the lower end of connecting bracket 11 can be smoothly inserted in the second jack 142, the hole wall of the second jack 142
Provided with least two gaps 143 that can be closed.Gap 143 can be set along the opening direction of the second jack 142.Gap 143
The area of the second jack 142 is expanded, can smoothly be inserted in the second jack 142 so as to the lower end of connecting bracket 11.Connection branch
The lower end of frame 11 is inserted after the second jack 142, it is necessary to the lower end of connecting bracket 11 is fixed in the second jack 142, in this reality
Apply in example, undercarriage also includes being used for the fixing nut 15 being fixed on connecting bracket 11 in second jack 142.Fixing nut 15
Preferably butterfly nut, so, connecting bracket 11 can be fixed without instrument.
As shown in figure 5, the utility model additionally provides a kind of aircraft.Aircraft can be that rotor craft or fixed-wing fly
Row device etc., aircraft may be used as unmanned plane perform take photo by plane, ground mapping, Investigating and rescue, aerial monitoring, transmission line of electricity
The tasks such as inspection.The aircraft includes fuselage 20 and the undercarriage 10 of previous embodiment, undercarriage 10 are detachably connected to
Specifically, the belly of fuselage 20 is provided with stud (not indicated in figure) to the belly of fuselage 20, and the upper end of connecting bracket 11 is provided with and stud
The fixing hole (not indicated in figure) to match, stud passes through fixing hole, and is fixed on connecting bracket 11 by butterfly nut 21
The belly of fuselage 20.
