Description
Technical field
The utility model is related to support technology field more particularly to a kind of foldable A-frames.
Background technology
At present, there are many tripod in the market for camera, video camera, and the main function of tripod is fixed camera
Material and adjusting shooting angle, it is either all very important for amateur user or its effect of professional user.General tripod
Body is directly connected with foot axle sleeve, by the swing of body connecting portion, directly adjusts putting for tripod.It can not roll over
Folded to use, occupied space is big, and inconvenience is brought to user's trip.
Utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of foldable A-frame.
The utility model to achieve the above object, using following technical scheme：
A kind of foldable A-frame, it is characterised in that：Including ball seat, three supporting legs, lock sleeve, locking jaw and connection
Bar, the ring week of the ball seat are uniformly opened there are three groove, and the top of three supporting legs is hinged respectively by hinge shaft and inside grooves, and three
The top of a supporting leg is respectively semicircle, and V-shaped groove is had on the top of three supporting legs, and the locking jaw is uniformly fixed respectively
On the lock sleeve, the connecting rod is fixed on the bottom of the ball seat, and the lock sleeve is sleeved in the connecting rod, described
The side wall of groove is equipped with locking jaw via, and the locking jaw is passed through from locking jaw via, the horizontal stroke on the top of the locking jaw
Rectangular triangle in the street.
Preferably, the plane on the top of the groove is parallel with the axis of ball seat vertical direction, the plane and ball seat of lower part
The axis of vertical direction is in obtuse angle.
The beneficial effects of the utility model are:Compared with the prior art, the present apparatus is simple in structure, three supporting legs can more than it is curved
It folds in groove, is hidden into ball seat, be so readily transported carrying, can be flipped out when in use from groove, form three
Due to special locking mechanism, self-locking is formed when bending downward when locking jaw is entered in V-shaped groove for angle support construction, can
Prevent three supporting legs oneself from rotating.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment of the present utility model is described in detail in preferred embodiment.Such as Fig. 1-Fig. 8 institutes
Show, a kind of foldable A-frame, including 1, three supporting leg 2 of ball seat, lock sleeve 3, locking jaw 4 and connecting rod 5, the ball seat
Uniformly open there are three groove 6 in ring week, the top of three supporting legs is hinged respectively by hinge shaft 7 with inside grooves, three supporting legs
Top is respectively semicircle, and semicircle can realize and be rotatably assorted with ball seat, in order to carry out /V to supporting leg, in three supporting legs
Top has V-shaped groove 8, and the locking jaw is uniformly fixed on the lock sleeve respectively, and the connecting rod is fixed on described
Certain gap is left in the bottom of ball seat between connecting rod and axle bed, the lock sleeve is sleeved in the connecting rod, and lock sleeve can
To be slided up and down in connecting rod, the side wall of the groove is equipped with locking jaw via 9, and locking jaw via is corresponding with locking jaw,
All it is three, when lock sleeve upward sliding, the locking jaw is passed through from locking jaw via, is exposed from locking jaw via,
Locking jaw can be entered in V-shaped groove if the V-shaped groove just rotating knife on the supporting leg top position at this time, so as to be carried out to supporting leg
Locking.The rectangular triangle in rank street face on the top of the locking jaw, top is parallel surface, is contacted with locking jaw via on groove
Position be an inclined-plane, downwards retract lock sleeve when locking jaw can be retracted from locking jaw via, consequently facilitating withdraw three
A supporting leg.
The plane on the top of the groove is parallel with the axis of ball seat vertical direction, plane and the ball seat vertical direction of lower part
Axis in obtuse angle.The structure can ensure the stability of three supporting legs.
During expansion, locking jaw is stuck in V-shaped groove, and locking jaw withstands V-shaped groove always under the action of the spring, ensures three branch
It is indeformable that leg forms gusseted.
During withdrawal, three supporting legs are moved upwards, and supporting leg overcomes the elastic force of spring to be recovered to upwards in groove.
The present apparatus is simple in structure, three supporting legs can more than be folded into groove, be hidden into ball seat, be so readily transported and take
Band can be flipped out from groove when in use, formed triangular support configurations, due to special locking mechanism, bent downward
When form self-locking when locking jaw is entered in V-shaped groove, can prevent three supporting legs oneself from rotating.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
