Description
Technical field
The present invention relates to unmanned vehicle field, more particularly to a kind of manual rotation locking has folded frame.
Background technology
In recent years, the advantage prominent since at low cost, maneuvering characteristics are good, survival ability is strong etc., unmanned vehicle technology have
Quick development all has boundless application prospect in military and civilian field, has important value.
The undercarriage generally use stationary structure of traditional unmanned vehicle, undercarriage are installed under each flight support arm
Side.Since unmanned vehicle support arm general structure rigidity is smaller, when landing, is easily damaged flight support arm.It is in the prior art
Some unmanned vehicle landing gear structure improvement projects are fixed on using detachable undercarriage or by undercarriage below rack.It tears open
The aircraft of formula undercarriage scheme undercarriage and fuselage when carrying is unloaded separately to store, it appears it is more scattered, it cannot achieve and rise and fall
The rapid deployment of frame.Undercarriage is installed below rack but so that multi-rotor aerocraft occupies empty with larger longitudinal height
Between it is big, storage transport can be given to make troubles.
Invention content
The purpose of this utility model is to overcome the above problem, provide a kind of simple structure, simple operation manual rotation
Twist lock folds undercarriage surely.
In order to achieve the above objectives, the method for the utility model use is：A kind of manual rotation locking folding undercarriage, including
Supporting rod, rack, locking mechanism, it is characterised in that：The remote ground terminal of the supporting rod is hinged with rack, can independently surround support
The junction of bar and rack carries out unitary rotation, completes expansion and folding movement；Every supporting rod and the hinged one end of rack are also
It is provided with locking mechanism, is used to support bar in the limit of working condition and the unlock of off working state；The locking mechanism packet
Include fixed limited block and rotary stopper block；The U-shaped ring of fixation limited block ground terminal remote with supporting rod is fixedly connected；The rotation
Turn limited block to be fixedly connected with rack, and can be rotated around its own axis.
Preferably, the supporting rod is provided with four to one kind as the utility model, and four supporting rods are distributed in two-by-two
Rack both sides.
Preferably, the near end of every supporting rod is fixedly connected one kind as the utility model with beam.
Preferably, for the undercarriage in working condition, supporting rod is rotated down expansion to one kind as the utility model,
In vertical direction with inclination, rotary stopper block is set to be contacted with fixed limited block by manual rotation rotary stopper block, to supporting rod
It is limited；Undercarriage makes rotary stopper block and fixed limited block in off working state, by manual rotation rotary stopper block
Separation, supporting rod, which rotates up, is retracted to vertical position.
Preferably, the fixation limited block and beam are rubber or high molecular material bullet to one kind as the utility model
Property element, for undercarriage work when damping.
Advantageous effect：
The utility model compares traditional scheme, and undercarriage is designed using folding, and it is vertical to reduce aircraft after folding
To height, it is readily transported.Meanwhile will rise and fall and being placed below rack, influence of the landing load for flight support arm is eliminated, this
Folding mode simple possible used by outer the technical program, simple operation, gear support bar can quick manual fold with
It is fixed, there is good reliability.

Fig. 1 is that manual rotation locking folds the structural schematic diagram after undercarriage expansion
Fig. 2 is the schematic diagram that manual rotation locking folds locking mechanism after undercarriage expansion
Fig. 3 is the schematic diagram that manual rotation locking folds locking mechanism after gear up
Each component is in figure：1, supporting rod, 2, cushion blocking, 3, rack, 4, locking mechanism, 1a, U-shaped ring, 4a, fixed limit
Block, 4b, rotary stopper block.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, the present embodiment is with the utility model
Implemented under premised on technical solution, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality
With novel range.
Embodiment 1：
As shown in Fig. 1, it is locked the utility model discloses a kind of manual rotation and folds undercarriage, including supporting rod 1, subtracted
Shake pad 2, rack 3, locking mechanism 4.
The supporting rod 1 is provided with four, and four supporting rods 1 are distributed in 3 both sides of rack two-by-two, every supporting rod 1
Near end is fixedly connected with beam 2, and remote ground terminal and rack 3 are hinged, can independently surround the junction of supporting rod 1 and rack 3 into
Row unitary rotation completes expansion and folding movement.Every supporting rod 1 is additionally provided with locking mechanism 4 with the hinged one end of rack 3,
Bar 1 is used to support in the limit of working condition and the unlock of off working state.The locking mechanism 4 includes fixed limited block 4a
With rotary stopper block 4b；As shown in Fig. 2, the fixation limited block 4a is fixedly connected with the U-shaped ring 1a of 1 remote ground terminal of supporting rod；Institute
The rotary stopper 4b blocks stated are fixedly connected with rack 3, and can be rotated around its own axis.
As shown in Fig. 2, the undercarriage, in working condition, supporting rod 1 is rotated down expansion, in vertical direction with one
Fixed angle of inclination makes rotary stopper block 4b be contacted with fixed limited block 4a, to support by manual rotation rotary stopper block 4b
Bar 1 is limited.As shown in figure 3, undercarriage makes rotary stopper in off working state, by manual rotation rotary stopper block 4b
Block 4b is detached with fixed limited block 4a, and supporting rod 1, which rotates up, is retracted to vertical position.
The fixation limited block 4a and beam 2 is rubber or high molecular material elastic element, is worked for undercarriage
When damping.
Technological means disclosed in the utility model is not limited to the technical means disclosed in the above technical means, also
Include by the above technical characteristic arbitrarily the formed technical solution of combination.It should be pointed out that for the ordinary skill of the art
